Description

TECHNICAL FIELD

[0002] This disclosure relates generally to methods and devices for making formed materials. More particularly, this disclosure relates to a block forming apparatus for making concrete blocks.

BACKGROUND

[0003] Blocks, such as retaining wall blocks, are frequently used in landscaping. Some typical blocks include tongue and groove configurations that easily stack to provide a sturdy wall. The blocks are manufactured in a variety of sizes to accommodate various landscaping applications and designs. The blocks may be manufactured from a variety of materials.

[0004] One such material includes ready mix concrete. Often excess ready mix concrete is returned from commercial or residential construction projects and dumped on the ground for disposal purposes. One solution in addressing this waste problem is to use the excess material in the manufacture of retaining blocks.

[0005] A formed block, apparatus and method of making the block using returned ready mixed concrete is disclosed in U.S. application Ser. No. 09/788,836, which is herein incorporated by reference. The method of manufacturing discloses an advantageous use for returned concrete. The returned concrete is poured into a block forming device to form large blocks for use in landscaping applications. The forming device includes four hinged doors secured to a bottom platform. Concrete is poured into the cavity formed by the doors and bottom platform. After the concrete cures for about 10-14 hours, the doors are pivoted outward and the hardened block is lifted from the device. In this arrangement, only one block can be produced within the curing time period of 10-14 hours.

[0006] Improvement has been sought with respect to such forming devices and methods of manufacturing of these large retaining blocks, generally to better accommodate production quantity and efficiency, and reduce the equipment cost associated with increasing production quantity.

SUMMARY

[0007] The present invention relates to a concrete block forming apparatus having a base support, a liner received within the base support and first and second jackets. The liner and first and second jackets define a molding cavity into which a moldable concrete is poured.

[0008] One aspect of the present invention relates to the detachable mounting structure of the first and second jackets. Another aspect relates to a transport device that attaches to a jacket at a first attachment location and is adapted to laterally slide the jacket from a partially cured block. The transport device may then be attached to the jacket at a second attachment location to transport the jacket to a second base pallet. Yet another aspect of the invention relates to a method of manufacturing concrete blocks using the detachable first and second jackets interchangeably with different base pallets.

DETAILED DESCRIPTION

[0039] With reference now to the various figures in which identical elements are numbered identically throughout, a description of various exemplary aspects of the present invention will now be provided.

[0040] In general, this disclosure describes improvements over the apparatus and methods of manufacturing retaining blocks of the U.S. application Ser. No. 09/788,836. While the apparatus and methods described in U.S. application Ser. No. 09/788,836 are improvements over the old methods and constructions of the prior art, there can still be further improvements. This disclosure concerns many such improvements.

[0041] For example, the apparatus disclosed in U.S. applicant Ser. No. 09/788,836 produces one block in the time period required for the block to cure. Block manufacturers desire to produce quantities sufficient to accommodate larger jobs. Because of the time involved in producing a single block, a number of block forming devices is required to produce larger quantities of blocks. The cost to purchase equipment to produce larger quantities of blocks can be considerable.

[0042] One improvement herein disclosed relates to an apparatus that increases production rate by permitting the enclosure portions of the block forming apparatus to be removed from the block and base while the block is only partially cured (i.e. 4 hours). Typically, the blocks cannot be removed from the form until the block is fully cured (i.e. 10-14 hours). By providing removable enclosure portions, the partially cured block can remain stationary in the base to continue curing, while the enclosure portions may be transported for use with another base to produce the next block. This permits a manufacturer to produce, for example, 3 blocks per day with one set of enclosure portions and 3 bases.

Blocks

[0043] Retaining wall blocks are typically stacked in layers, one on top of the other, to form a retaining wall. The vast types of landscaping applications and locations require different size and shape retaining walls. One example of a retaining block that may be manufactured in accordance with the principles disclosed is illustrated in FIGS. 1 and 2.

[0044] The retaining block of FIGS. 1 and 2 is a full block 10 having a tongue 12 protruding from a top surface 14 of the block. The full block 10 also includes a groove 16 in a bottom surface 18 of the block. The tongue of one block generally corresponds to the groove of another block to provide a stable wall structure.

[0045] A retaining wall may include one or more different types of retaining wall blocks. The full block 10 of FIGS. 1 and 2 is illustrated for explanatory purposes only. Other types of blocks, including half blocks, corner blocks and top blocks may be manufactured in accordance with the principles disclosed.

Block Forming Apparatus

[0046] FIGS. 3-6 illustrate one embodiment of a block forming apparatus 20 according to the principles disclosed. The block forming apparatus embodiments herein described are not intended to be limited to forming the blocks described above. Further, one possible use of the disclosed apparatus is for utilizing moldable returned concrete such as wetcast concrete. The use of returned concrete is one exemplary use of the block forming apparatus herein disclosed. The block forming apparatus embodiments described are not limited to being used with returned concrete.

[0047] The block forming apparatus or block form 20 shown in FIGS. 3-6 generally includes a base support or base pallet 22, first and second enclosure components or jackets 24, 26, and a jacket transport 28. The first and second jackets 24 and 26 detachably mount to the base pallet 22 to form an enclosure into which moldable concrete can be poured.

[0048] Referring first to FIGS. 13-15, the base pallet 22 of the block form 20 includes a supporting structure 30 that supports the first and second jackets 24, 26. As shown in FIG. 13, the supporting structure 30 of the base pallet 22 includes two parallel beams 32 and 34 supported by offset members 36. The offset members 36 are welded, or secured by other fastening means, to a flat platform 40. End plates 42 and 44 are fastened to the beams 34, 36. The end plates 42, 44 including support fins 46 to provide structural stability to the supporting structure 30 of the base pallet 22. The end plates 42, 44 and beams 32, 34 define a liner receiving area 48 into which a liner 50 (shown in FIG. 16) may be placed or positioned.

[0049] The base pallet 22 further includes retaining structures or flanges 52. In the illustrated embodiment, the base pallet includes four flanges 52 located at each of the corners of the base pallet 22. Each of the flanges 52 extends generally perpendicular from the platform 40. The flanges 52 include slots 54 used for securing the jackets 24, 26 to the base pallet 22.

[0050] Referring now to FIGS. 9-12, each jacket 24 and 26 of the block forming apparatus includes an end member and a side member. As shown in FIG. 9, the first jacket 24 has a first end member 56 joined to a first side member 58. The second jacket 26 has a second end member 60 joined to a second side member 62. The end members 56, 60 are generally shorter than the side members 58 and 62. In the illustrated embodiment, the end and side members of each jacket are generally perpendicular to one another and have an L-shaped configuration.

[0051] Each of the jackets 24 and 26 detachably mounts to the base pallet 22. As shown in FIG. 9, the first jacket 24 couples to the base pallet 22 in a position opposite from the second jacket 26. When assembled, the base pallet 22 and the jackets 24 and 26 define an interior molding cavity or enclosure 64 (best shown in FIG. 6) into which moldable concrete is poured. In a preferred embodiment of the block form, the jackets 24, 26 include interior molding surfaces 66, 68. The interior molding surfaces 66 and 68 contact the moldable concrete directly.

[0052] In the illustrated embodiment, the molding surfaces are strengthened by two or more gussets 70 (shown in FIG. 10) that extend in a generally vertical orientation. More or fewer gussets than shown in the embodiment may be utilized depending on the weight that the jacket must withstand, which depends upon the amount of moldable concrete used. Furthermore different size and shaped gussets may also be used.

[0053] The molding surface of a block form may be shaped in such a way as to create tongue and groove sets on the block being formed. For example, to arrive at the full block 19 illustrated in FIGS. 1, 2 and 8 of this application, the first jacket 24 includes a recession 72 (shown in FIGS. 4, 5 and 10) on the wall of its interior molding surface 66 to result in formation of the tongue 12 in the top surface 14 of the block 10. The second and opposite jacket 26 on the block form 20 includes a protrusion 74 (shown in FIGS. 4 and 11) in the shape of the groove 16 formed on the bottom surface 18 of the block. The recession 72 and the protrusion 74 in the molding surfaces 66, 68 of the jackets 24, 26 can be any shape desired. The block form 20 of this invention is not limited to the formation of the retaining wall blocks described above.

[0054] As shown in FIG. 11, each of the jackets 24, 26 includes upper coupling brackets 76 positioned toward an upper region 78 of the jacket 24, 26. The upper brackets 76 are located at a distance D apart from one another and offset from a center of the side of each jacket (see FIG. 12). The upper brackets 76 include holes 80 for coupling with the jacket transport 28 (see FIG. 4), which is described in greater detail hereinafter.

[0055] Still referring to FIG. 11, each of the first and second jackets 24, 26 also includes lower brackets 82 positioned at a lower region 84 of the jacket 24, 26. Each of the lower brackets 82 includes a through hole 86 sized to correspond to a securing rod 88 (FIG. 9). In the illustrated embodiment, four lower brackets 82 (FIG. 10) are securely mounted to the side of each jacket. Each securing rod 88 slides through the holes 86 of the lower brackets 82 and couples each of the jackets 24, 26 to the base pallet 22, shown in FIGS. 3-6. In particular, securing rods ends 90 engage the slots 54 of the flanges 52 on each of the corner of the base pallet 22 so that the jacket cannot ride up when the block form is filled with concrete. This connection configuration securely holds the jackets in place while at the same time does not require a user to bolt, fasten or hinge the jackets to the base pallet, thus making placement and removal of the jacket quick and easy. In addition, as will be described herein, the rods 88 are used in cooperation with the jacket transport to remove the jacket from the base pallet and transport the jacket to a different location.

[0056] In the preferred embodiment, the liner receiving area 48 of the base pallet is sized to receive a form face or liner, such as the liner 50 shown in FIG. 16. A liner is a shaped member for forming the aesthetically pleasing front surface of a block. The liner 50 may have any shape or design that creates the desired front surface of the block being formed. The liner may be utilized to form blocks with one front surface or additional liners may be used to form blocks with multiple front surfaces such as corner blocks. The liner 50 is placed at least partially within the liner receiving area 48 of the base pallet 22.

[0057] The liner in accordance with the principles disclosed includes a bottom surface 160 textured to the desired ornamentation. The liner may be made of any material that is capable of being formed into the desired shape and that prevents the moldable concrete from flowing through the base pallet 22 of the block form 20. In one embodiment the liner 50 is made of urethane, which is easily formed to the desired shape.

[0058] It is desired to be able to easily remove the liner from the block form for cleaning, repair, or replacement of the liner. As shown in the embodiment of FIG. 16, the liner may include rail or flanges 162 designed for sliding engagement with the base pallet 22. In an alternative embodiment, the liner may include a bolt down structure for example. Of course, the slidable liner makes the method and structure even more attractive and efficient.

[0059] Referring now to FIGS. 17-19, another embodiment of the block form 220 is shown with jackets 24 and 26 assembled to the base pallet 22. This second embodiment differs slightly from the first full block embodiment by modifying the interior molding surfaces 66′ and 68′ of the jackets to form corner blocks (not shown). The base pallet 22 is also slightly modified to include a base panel or spacer 170 adjacent the end plate 42 to make a second finished surface of the corner block.

[0060] With respect to alternative embodiments disclosed herein, locking mechanisms 92 are provided to securely hold the first and second jackets in their molding position while the moldable concrete is being poured into the block form 20 as well as during the initial curing stage. A locking mechanism is any mechanism that retains the jackets in their positions during these steps.

[0061] In the embodiment shown in FIG. 17, the locking mechanisms utilized are upper and lower over-center clamps 94 and 96. In particular, the upper and lower over-center clamps 94 and 96 illustrated are ten-inch Concrete Form Clamps made by Best Metal Clamps. In an alternative embodiment, the locking mechanisms may comprise upper over-center clamp that retain the upper regions 78 of the jackets and wedge pieces 98 (shown in FIG. 15) that retain the lower regions 84 of the jackets.

[0062] As shown in FIGS. 13, 15 and 17, the wedge pieces 98 are constructed to slidably fit within wedge brackets 100. The wedge pieces 98 wedge the securing rod 88 in position within the slots 54 of the retaining members 52 to retain the lower regions 84 of the jackets when only an upper over-center clamp 94 is used (see FIG. 4).

[0063] In use, a bond sometimes forms between the concrete block and the jackets during the curing process. It is desired to have a pry point at which a crowbar or other similar tool may be inserted into the block form to break the bond and pry open the first and second jackets after the moldable concrete has at least partially cured. As shown in FIGS. 11 and 17, channels 102 are located on each of the sides of the block forms between each of the first and second jackets 24, 26. In particular, a first channel 102 is defined between an edge 106 of the end member 60 of the second jacket 26 and an edge 108 of the side member 58 of the first jacket 24. A second channel (not shown) is defined between an edge of the end member 56 of the first jacket 24 and an edge of the side member 62 of the second jacket 26. In the illustrated embodiment, each of the edges of the end members 56 and 60 includes a lip 164 (shown on edge 106 of the second jacket member 76) that projects outward from the outer surface of the end members.

[0064] The channels 102 extend generally along the length of the jackets. In an alternative embodiment, the channel may extend only a portion of the length of the jackets, or be located adjacent only the upper region or the lower region or both regions of the jackets. The jackets of the block form 20 may further include pry locations having reinforcement structures against which a pry tool may be used to separate the jackets and the block.

[0065] Referring now to FIGS. 20-23, the jacket transport 28 is used to remove and transport the jackets from the block forming apparatus 20. It is to be understood that this jacket transport 28 can be used in accord with the principles disclosed to remove and transport the jackets from each of the disclosed block forming apparatus embodiments. The jacket transport 28 generally includes a frame 114 having a front side 124, a back side 126, a top region 130, a bottom region 132, and a middle region 134. Wheels 116 are attached to the back side 126 of the frame 114 at the bottom region. The jacket transport also includes upper and lower jacket attachments 118 and 120.

[0066] The frame 114 includes a first handle portion 122. The first handle portion 122 is located at the top region 130 of the frame and extends at an angle from main transport frame members 136. The jacket transport 28 further includes a nose plate 140 extending forwardly from the front side of the frame 114 and wheel mount brackets 142 extending backwardly from the backside of the frame 114. The wheels are mounted to a wheel axle 144 that extends through each of the wheel mount brackets. In addition to structurally providing a wheel mounting location, the wheel mount brackets structurally support the frame 114 in carrying the weight of the jackets.

[0067] The lower jacket attachments 120 include lower brackets 148 that extend outwardly from the front side 124 of the frame 114. The lower brackets 148 may be welded to the main frame members 136 and include slots 150 defining a hook portion 152 that mounts onto the rod 88 of the jacket. As will be described in greater detail, the nose plate 140 and the slot 150 are configured so that when the slot is hooked onto the rod 88 of a jacket, a trim piece 154 (FIG. 21) contacts the base pallet 22 of the block form 20. This trim piece 154 provides a fulcrum point at which the transport is pivoted away from the block form 20 to laterally move the jacket away from the base pallet 22 and block 10.

[0068] The upper jacket attachments 118 include upper brackets 146 that extend outwardly from the front side 124 of the frame 114. The upper brackets 146 are attached to the main frame members 136 at a distance d1 from the nose plate. The distance d1 corresponds to the location of the brackets 76 (shown in FIG. 17) of the jackets 24, 26. Pins 158 attached to the transport are used to couple the upper brackets 146 to the jacket brackets 76 when the slots 150 of the lower brackets 148 of the transport 28 are engaged with the rod 88 of the jacket.

[0069] The frame 114 and the wheels 116 are similar to standard dollies known in the industry. It is contemplated that other frame and wheel dolly configuration may be used in accordance with the principles disclosed. In particular, it is contemplated that other frame and wheel configurations may be adapted with upper and lower jacket attachments as disclosed.

[0070] It is also contemplated that structural features of the transport may be permanently or detachably mounted to the jackets so that the jacket and its transport mechanism are integral. For example, the jackets may include wheels and a pivoting member that operates in similar fashion as the stand alone transport in laterally removing and moving each jacket.

[0071] In use, it is desirable that one person be able to move the jackets from one base pallet to another base pallet without assistance from another person. Such task must also be performed in a safe manner. A method by which one person manufactures a block and moves the two jackets 24, 26 of the block form 20 from a first base pallet to a second base pallet will now be described.

[0072] The liner 50 (FIG. 16) is placed within the liner receiving area 48 of the base pallet 22 (FIG. 13). The bottom surface 160 of the liner creates a natural stone texture to the face of the block. The first jacket 24 (FIGS. 6 and 9) is placed upon the base pallet 22 by slidably positioning the ends 90 of the securing rod 88 of the first jacket within the slots 54 of two corner retaining members 52 of the base pallet 22. The second jacket 26 is placed upon the base pallet, opposite the first jacket 24, by slidably positioning the ends of the securing rod 88 of the second jacket within the slots 54 of the opposite two corner retaining members 52.

[0073] The upper over-center clamp 94 is engaged to secure the upper regions 78 of the jackets 24, 26. The lower over-center clamp 96 is engaged, or in the alternative wedge pieces 98 are inserted into the wedge brackets 100, to secure the lower regions 84 of the jackets. The liner 50 and the first and second jackets 24 and 26 define the interior molding cavity 64 of the block form 20 into which moldable concrete is then poured to form a concrete block.

[0074] The moldable concrete is permitted to set up or cure for approximately four hours. It is contemplated that additives and/or heat can be added to the concrete used to produce the block, thus accelerating the cure time. With such additives it would be possible to increase production of blocks per day.

[0075] Once the concrete has partially cured (approximately four hours) the jackets 24,26 may be removed. This is accomplished by use of the jacket transport 28. Each jacket weighs approximately 180 pounds, thus the transport 28 has been adapted to permit a user to safely and easily transport the jacket from base pallet to base pallet.

[0076] In removing the jackets 24, 26 from the base pallet 22, a seal or bond which exists after the concrete has initially set up or cured within the block form must first be broken. The jackets are configured so that there are three methods of breaking the bond between the block and the jackets.

[0077] First, the over-center latches 96 that are used to lock or clamp the two jackets 24 and 26 together can also serve to pry the jackets apart. These latches are off the-shelf ordinary latches used on many concrete forms. Second, the transport 28 may be coupled to the securing rod 88 and the handle of the rod 88 pulled backward and away from the block form 20 to provide lateral force to break the bond. Third, if all else fails, a pry tool (not shown) can be inserted with the pry channels 102 located along each end of the jackets to pry the jackets apart and break the bond. The block form 20 configuration permits the operator to attempt to break the bond from several different directions thereby increasing the likelihood that the bond will be broken without damage to the block form 20 or the block 10.

[0078] Once the bond is broken, the jackets can be removed. In removing the jackets from the base pallet, the transport is lifted and coupled to the first jacket 24, for example, by engaging the slots 150 of the lower brackets 148 with the securing rod 88. In this arrangement, the transport is attached to the first jacket only at the bottom of the jacket. The operator then pulls back on the handle 122 of the transport 28 to pivot the transport 28 away from the block form 22.

[0079] When the transport is coupled to the jacket at only the securing rod and pulled backward, the nose plate 140 functions as a fulcrum point. That is, the transport pivots downward until the wheels 116 contact the ground surface. As the transport 28 is pivoting, the hook portions 152 retain the rod 88 of the jacket to laterally pull or slide the jacket straight back without tilting or rotating of the jacket. This is advantageous in that the jacket pulls straight back and avoids tipping or slipping off the block form 20 or block 10 to damage the tongue or groove sections of the concrete block 10. This also does not bind the jacket against the tongue and grooves of the concrete block. Once the jacket is laterally slid backward about three inches and the tongue and groove sections of the block have been cleared, the transport 28 can be tilted forward toward the jacket and attached to the jacket at the upper brackets 146. As shown in FIG. 22, the pins 158 couple with the brackets 76 of the jacket 24, 26. With the transport 28 attached to both the upper and lower regions 78, 84 of the jacket, the operator can tip the transport backwards and the top portion of the jacket will rotate back with the transport and not bind against the tongue or groove section of the block (see FIGS. 5, 7 and 8). The operator may now move the jacket on the wheels of the transport to another base pallet.

[0080] As shown in FIG. 8, the partially cured block may remain standing within the base pallet and the liner until it is fully cured. In the meantime, the jackets can be moved to a second empty base pallet, mounted, and a second block can be poured. Three to four hours later the jackets can be removed from the second base pallet and placed on a third base pallet. When the blocks are fully cured, they may be lifted from the base pallets and liners and stored. By this method, three blocks can be made in nine to twelve hours, requiring only three base pallets and a pair of block form jackets, for example.

[0081] Referring now to FIGS. 24-27, first and second jackets 324 and 326 of a half block form 320 is illustrated. The half block form 320 is similar to the full block form 20 except that the sides are half the width of the full block form. A base support 322 of the half block form (shown in FIGS. 28-30) is accordingly sized and configured. The half block form 320 illustrates an alternative embodiment according to the principles disclosed. Likewise top block pieces and other corner block pieces can be made using jacket and block form embodiments with different configurations in accordance with the principles disclosed.
