1. Field of the Invention
The present disclosure relates to masonry, and more particularly to insulating building blocks used in the masonry field.
2. Background of the Invention
The present invention is aimed at improving upon the insulated building block disclosed in U.S. Pat. No. 4,856,249 to Nickerson (“'249”). '249 discloses a two web concrete block having an insulation insert placed within the core of the block to provide thermal insulation over the face of the block except where the cross-ties or webs are located. The insulation insert disclosed in '249 comprises two parts held together by plugs on one part and corresponding holes on the other part. Such a design allows the plug-bearing part to be pushed down against the hole-bearing part thereby causing the plugs to shear off and allowing the former plug-bearing part to slide down to ship lap an insulating insert located in a block located directly below.
The insulated building block disclosed in '249 has several design flaws. For example, the plug and hole design of the insulation insert prevents reuse of the insulation insert once the plugs are shorn off. That is, once the plugs are shorn off, the insulation insert is effectively a two-piece structure which is difficult to work with if there becomes a need to reinstall the insulation insert in a block while a wall is being constructed.
Additionally, the design of the block in '249 has the length of the block extended to protect the vertical edges of the insulation insert that were extended to interlock with the adjacent insulation insert. During packaging of the masonry units in large cubes of blocks, the extended pieces of the block are easily damaged, thereby causing the blocks to be rejected. Additionally, the insulation insert extends above the block at a top side thereof which causes the insulation insert to become crushed or broken.
Also, when water is forced against the face of a masonry wall built from masonry units disclosed in '249, the water can migrate through the outside face shell of the block. Once the water reaches the insulation insert, there is no direct path for the water to run out of the face shell, and the water, therefore, continues to build up in the block's face shell. This water build-up causes damage and negatively affects the physical appearance of the wall.
The physical design of the insulation insert disclosed in '249, in addition to the thickness of the face shell of the block, makes the masonry unit difficult to handle. Typically, a mason picks up a block by grabbing the web or face shell of the block. However, the location of the insulation insert relative to the block, as disclosed in '249, prevents the mason from extending his grip wide enough to safely handle the block.
Also, steel reinforced block walls oftentimes have vertical reinforcing rods or rebars placed in the core of the blocks. These rebars become part of the wall when concrete grout is poured around the rebars to bond them to the wall in a specific location. However, the height of the web of the block makes it difficult to control the flow of the grout. Currently, there is to no method of preventing the grout from flowing over the top of the web into a core that is not to be grouted.
The above mentioned disadvantages and draw-backs of the prior art are alleviated or greatly overcome by a masonry unit comprising a block and an insulation insert. The block comprises a web transversely formed and centrally connected to an anterior face shell and a posterior face shell. The anterior face shell comprises a top side which slopes downwardly towards and is contiguously formed with an exterior directed side of the anterior face shell such that the exterior directed side has a lower height compared to an oppositely situated interior directed side of the anterior face shell. The web has formed on each of oppositely situated abutment side walls thereof a vertically extending groove.
The insulation insert comprises a first insulation member and a second insulation member. The first insulation member comprises a forward wall oppositely situated to a rearward wall, a proximal lateral wall oppositely situated to a distal lateral wall, and a top side oppositely situated to a bottom side. The top side comprises a substantially planar portion contiguously formed with the rearward wall, and a sloped portion that slopes downwardly towards and is contiguously formed with the forward wall. The substantially planar portion of the top side comprises a recessed portion centrally formed therein. An opening, which is aligned with the recessed portion of the top side, is centrally formed through the forward wall and the rearward wall and extends from the bottom side towards the top side where it terminates at an abutment wall. A pair of thumb grips is formed on the forward wall, while a pair of engagement members, such as, e.g., plugs, wherein the pair of engagement members is formed on the rearward wall. Each of the thumb grips has a weep hole formed therein. A respective channel extends from the weep holes formed in the thumb grips to a terminal end of the forward wall of the first insulation member.
The second insulation member comprises a rearward wall oppositely situated to a forward wall, a top wall oppositely situated to a bottom wall, and a proximal lateral wall oppositely situated to a distal lateral wall. An opening is centrally formed through the forward wall and the rearward wall and extends from the bottom wall towards the top wall where it terminates at an underside of an abutment portion. The rearward wall comprises a pair of engagement members, such as, e.g., substantially vertically extending grooves formed therein, wherein engagement members are separated from one another by the opening of the second insulation member. In an exemplary embodiment, the pair of engagement members comprises a pair of grooves, wherein each of the grooves is formed in the rearward wall, extends to the bottom wall, and is further formed therein.
The second insulation member may further comprise a pair of flanges. Each of the flanges, which are oppositely situated from one another, may extend from the forward wall and towards and into the opening. The second insulation member may further comprise a pair of plates, wherein each plate may be positioned on opposite sides of the opening of the second insulation member and which may perpendicularly extend from the top wall and from the rearward wall of the second insulation member.
The masonry unit may be composed by engaging the engaging members on the rearward wall of the first insulation member with the engaging members on the rearward wall of the second insulation member such that the openings of the two members are aligned, and such that the top wall of the second insulation member is directed towards the top side of the first insulation member.
The resulting insulation insert may then be positioned on the block so that the flanges of the second insulation member are engaged with the grooves formed on the web of the block, the respective undersides of the abutment wall and the abutment portion of the insulation insert abut a top wall of the web, and the lateral sides of the insulation insert extend past the lateral side of the anterior face shell of the block. When used, the plates of the second insulation member flank the top side of the web.

Insulation insert 10 may be positioned within an exemplary block 201 as shown in
Each of face shells 204 and 206 comprises a respective top side 208 and 210 oppositely situated to a respective bottom side 212 and 214, a respective interior-directed side 216 and 218 oppositely directed to a respective exterior-directed side 220 and 222, and a respective lateral side 224 and 226 oppositely directed to a respective lateral side 228 and 230. Top side 208 tapers downwardly towards and is contiguous with exterior-directed side 220 of anterior face shell 204 such that a vertical height of anterior face shell 204 is lower at exterior-directed side 220 by about ⅛ of an inch compared to a vertical height of interior-directed side 216. Such a difference in height protects insulation insert 10 from being compressed by the weight of a masonry unit(s) that lie(s) above masonry unit 200 during cubing, prevents water from flowing into the mortar joint as the water flows down anterior face shell 204, and allows compaction of mortar at interior-directed side 216 when a mortar joint is tooled as less space is created at interior-directed side 216.
Web 202 comprises a top side 232 directed towards top sides 208 and 210 and oppositely situated to a bottom side 233. Top side 232 comprises a horizontal length that extends from interior-directed sides 216 and 218 of respective face shells 204 and 206. Top side 232 further comprises a recessed portion 234 that extends along the horizontal length of top side 232. Recessed portion 234 is flanked on a side thereof by a sloped lateral wall 236 which slopes away from recessed portion 234 downwardly towards an abutment side wall 238, and is flanked on an opposite thereof by a sloped lateral wall 240 which slopes away from recessed portion 234 downwardly towards an abutment side wall 242. Abutment side walls 238 and 242 are contiguously formed with bottom side 233. Furthermore, each of abutment side walls 238 and 242 comprises a respective groove (not shown) formed therein, wherein the groove is transversely formed relative to bottom side 233.
When insulation insert 10 is assembled on block 201, flange 116 engages with the groove formed in abutment side wall 238 and flange 118 engages with the groove formed in abutment side wall 242 to thereby secure insulation insert 10 in a vertical position and to thereby prevent insulation insert 10 from slipping out of position. Underside 25 of abutment wall 28 and underside 102 of abutment portion 104 abut top side 232 of web 202 and are guided thereon by sloped lateral walls 236 and 240. Top side 208 extends above top side 22 and top wall 76, and sloped portion 40 of top side 22 of first insulation member 12 abuts interior-directed side 216 of anterior face shell 204. Additionally, lateral walls 20 and 82 of insulation insert 10 extend past lateral side 228 of anterior face shell 204, and lateral side 224 of anterior face shell 204 extends past lateral walls 18 and 80 of insulation insert 10.

As would be obvious from a reading of the above-disclosure in light of the figures and claims included herein, the masonry unit described above has several advantages over the prior art. For example, the newly designed plug and groove feature provided on the respective first and second insulation members allows the insulation insert to be removed easily from a broken block, and further allows the first and second insulation members to be engaged with one another for use in another block.
The slope added to the top side of the first insulation member, along with the weep hole provided at the bottom of the thumb grips, provide a drainage path for water to drain out of the weeps located at the bottom side of the first insulation insert member. Additionally, the slope provided at the bottom side of the first insulation member provides a path for water to flow away from the masonry unit.
The thumb grips provided in the forward wall of the first insulation member allow the mason to grip the face shells of the block more readily.
Additionally, placement of the insulation insert onto the block and the hold of the insulation insert once positioned on the block have been enhanced. The depression formed on the top side of the web of the block assists in guiding the insulation insert into a vertical position. Additionally, by providing the second insulation member with a first and second flange, and by providing the web with a first and second groove respectively formed on opposite abutment side walls of the web, wherein the first flange is received within the first groove and the second flange is received within the second groove, the insulation insert is vertically held in place on the block.
Furthermore, the use of plates on the second insulation member which flank the abutment side walls of the web of the block prevents liquid grout from flowing into adjacent block cores.
A slope has been formed at the top side of the anterior face shell of the block so that a vertical height of the exterior-directed side of the anterior face shell is lower than a vertical height of the interior-directed side of the anterior face shell. Such slope protects the insulation insert from being compressed by the weight of the masonry units located above the insulation insert during cubing. The slope also prevents water from working its way into the mortar joint as the water runs down the anterior face wall. The slope also prevents compaction of mortar at the interior-directed side of the anterior face wall compared to the exterior-directed side of the anterior face wall when the mortar joint is tooled.
A method of cubing the masonry blocks is further provided, wherein such method is used in lieu of extending the length of the block, thereby, protecting the insulation inserts from breakage.
The foregoing description of the preferred embodiment of the invention is to be considered as illustrative and not as limiting. Various other changes and modifications will occur to those skilled in the art for performing substantially the same function, in substantially the same way, to achieve substantially the same result without departing from the true scope of the invention as defined in the appended claims.
