Referring now to the drawings,
A modular form 100 according to some embodiments of the present invention includes base plate 102, one or more connection units 104, a plurality of rebar supports 106.
The base plate 102 has a plurality of sides and at least one knock-out 108. Each knock-out 108 is configured to be removed to generate a respective perforation 110 on the base plate 102, the perforation 110 is configured to be traversed by a pile 112. At least one of the sides of the base plate 102 is straight.
The connection units 104 are aligned with respective knock-outs 108 and are joined to the base plate 102 and held above the base plate 102. Each connection unit is configured to receive a pile 112 to create a connection between the pile 112 and the form 100.
The rebar supports 106 are configured to support rebars 114 above the base plate 102. At least some of the rebar supports 114 are configured to be joined to a portion of a connector 116. The remaining portion of the connector may be connected to a rebar support of a second modular from 200 similar to the modular form 100, or to a wall 300. Joining connector 106 to rebar supports of two contiguous modular forms 100 and 200 joins the modular forms together. When the remainder of the connector 116 is joined to a wall 300, joining the connector 116 to a rebar support 106 of the modular form joins the modular form to the form wall 300, such that the form wall contacts the base plate and rises from the base plate. In
The rebar supports 106 are therefore configured to support rebars 114 and some of the rebar supports are configured to connect a modular form to other modular forms and/or two wall. In this manner, a foundation is created.
As shown in
In some embodiments of the present invention, at least some of the rebar supports 106 are lined in one or more rows. Each row located above and along a respective straight side of the base plate 102. In this manner, a rebar is supported by a pair of rebar supports. In the non-limiting example of
In the example of
It should be noted that the each of the curved sides 154 and 164 can be replaced by a plurality of straight sides at angles with each other, such that a loop is created the forms 140 and 160 are joined to each other.
In some embodiments of the present invention, the rebar supports 106 are lined up, such that a first row of rebar supports is located above a second row of rebar supports. In this manner on each side, one row is used to support and hold rebars while the other row is used for being connected to a connector to join the form to another form or to a wall. For example. On sides A and B, the rebars 114 are held by the rebar supports on the bottom row, leaving the rebar supports on the upper row free to be joined to connectors 116, while on sides C and D the rebars 114 are held by the rebar supports on the upper row, leaving the rebar supports on the lower row free to be joined to connectors 116. In the example of
In some embodiments of the present invention, successive rebar supports of the upper row are joined by horizontal rigid rods 118. The rebar supports of the lower row on the same side are joined to the respective rebar supports on the upper row by vertical rigid rods 119. Spacers 120 are joined to at least two rebar supports on the lower row and to the base plate 102, to keep the rebar supports 106 above the base plate 102.
As seen in
Referring back to
In the example of
In some embodiments of the present invention, each connection unit 104 comprises an open or closed loop configured to be traversed by a pile 112. The pile 112 may be held by the connection unit 104, for example, by being screwed to the connection unit 104.
In some embodiments of the present invention, the form further includes an end cap 400 configured to receive the pile within the cap 400 and be secured to the pile 112. The cap 400 has an upper section 402 and a lower section 404. The upper section 402 is larger than the loop forming the connection unit 104 and the lower section having 404 an outer surface configured to traverse the loop. Thus, when the pile is secured to the cap 400, the top section 402 of the cap is located above the loop section, preventing form moving upward with respect to the pile 112.
In some embodiments of the present invention, the lower section 404 of the cap 400 has an outer threading 406 on the outer surface of the lower section of the cap.
In some embodiments of the present invention, the cap 404 has an inner threading 408 configured to cooperate with a threading of the pile, such that the cap 400 is configured to be secured to the pile via cooperation between the cap's inner threading 408 and the threading of the pile 112.

In some embodiments of the present invention, the base plate 102 has a recessed trough 600 under at least one of the one or more connection unit 104. The recessed trough 600 enables the form to hold more cement near the perforation traversed by the pile, thus securing the pile to the form more strongly once the cement has dried around the pile.
In some embodiments of the present invention, the modular form has a single connection unit 104. The recessed section is located under the single connection unit. In a variant, the recessed section is shaped as at least two troughs 600 and 602 crossing each other under the single connection unit.
The support brackets 700 are joined to an upper surface of the base plate 102 and to at least one of the connection units 104 to support the connection unit above the base plate 102.
In a variant, the bracket support brackets 700 are an angling bracket configured to change an angle the connection unit 104 with respect to the base plate. For example, each support bracket 700 may include a slit 702. The slit 702 is traversed by one or more fastener 704 joined to the connection unit 104, such that the bracket 700 is located between a head of the fastener (which is larger than the slit) and the connection unit 104. The fasteners may be loosened from the connection unit 104, enabling motion of the connection unit 104 with respect to the bracket(s) 700. Once the connection unit 104 has reached a desired height along a bracket, the fastener is tightened, thereby securing the connection unit to the fastener at the desired height. The connection unit 104 may thus secured to the brackets at different heights. In this manner, the angle of the connection unit 104 with respect to the base plate 102 can be changed. This is advantageous, as the piles may have different orientations, and the orientation of the connection units 104 can be changed to ensure that the base plate remains at a desired angle with the respect to the horizontal.
The fasteners may be, for example, screws or bolts that can be screwed into an out of the connection unit 104.
In some embodiments of the present invention, the connection unit includes a plurality of parallel loops joined together. The loops may be coplanar. This configuration enables a plurality of piles to be joined to a single form. Moreover, this configuration enables a user to select the loop(s) into for connecting to the form, thus giving the user a higher degree of freedom when planning the construction.
