An accessory kit for reusable footing forms (1001, 1002) used in conjunction with insulated concrete forms or steel panel wall forms. The kit includes an inside corner mold (500) and an inside corner form (600) that attach to the footing forms (1001, 1002). The inside corner molds are secured by slotted fasteners (410, 440) that are adjustably positioned and fastened by wedge bolts (400). The kit also includes outside corner molds (100, 200) that is adjustable to accommodate a variety of final wall configurations. An adjustment lever (600) is provided to assist in positioning two abutting footing forms (1001).

The present invention is a trench kicker for use in a concrete form system. A trench kicker is configured to provide lateral support to concrete form panels on horizontal surfaces as well as along embankments or trench walls. Features of the embodiments of trench kickers disclosed herein include horizontal and/or vertical adjustment of the form panel height and/or angle of the form panel relative to vertical. Another feature is selective tension adjustment along a horizontal support member. The trench kickers are configured to receive one or more stakes for secure placement into ground.

A magnetic concrete construction keyway system for strengthening adjacent concrete slabs through the use of a reusable and flexible keyway forming apparatus. The magnetic concrete construction keyway system includes a steel form to create a mold for a concrete slab, a keyway member including a connecting side, wherein the connecting side is removably attachable to an inside of the steel form and wherein the keyway member forms a groove in the concrete slab. The keyway member is magnetically attached to the steel form through the use of a plurality of magnets embedded within the keyway member.

The invention is an integral form panel for use in concrete form systems. Embodiments of an integral form panel may include a flat panel portion including a plurality of grade slots configured for receiving a grade clip and a plurality of tie slots configured for receiving a tie therein. The integral form panel may further include a top lip adjacent to an upper edge of the flat panel portion, the top lip including a plurality of holes configured for receiving a stake therein. Embodiments of a concrete form system including the integral form panel and methods of using same to form concrete footings are also disclosed.
摘要:
A brace for concrete forms employing first and second form elements includes at least one attachment member adapted and constructed to secure the brace to at least one of the form elements. A span member is connected to the at least one attachment member, and has a length sufficient to hold the first and second form elements apart. At least one article securing mechanism is movable between a first position in which the securing mechanism receives an article associated with the concrete form, and a second position in which the securing mechanism secures the article associated with the concrete form to the brace.
摘要:
Improvements to systems for building structures of reinforced concrete or other materials using high precision modular, integral coffering of the type of systems that use standardized panels preparing integral cofferings in which the reinforcements and various installations are placed, building the coffering on a foundation slab with the help of a layout template, in which the foundation slab is built using a mould based on modular pieces whose faces form a straight dihedral and squares for the corners the pieces of which are fixed with centering clips with angular reinforcements to fix stabilizers and anchorings, these pieces to having lugs for centering the layout template. Wall templates are also used to lay out the partitions and walls, with all their installations, and new means and panels for specific building solutions.
摘要:
A pre-cast panel forming system. The system includes one or more bulkheads to constrain the flow of uncured panel-forming material. The bulkhead is made up of an upstanding form and a base clip to secure the upstanding form to a panel-forming surface. The base clip is configured to promote ease of attachment to the panel-forming surface, even though the thickness dimension of the upstanding form is reduced relative to conventional forms. In accordance with 37 CFR 1.72(b), the purpose of this abstract is to enable the United States Patent and Trademark Office and the public generally to determine quickly from a cursory inspection the nature and gist of the technical disclosure. The abstract will not be used for interpreting the scope of the claims.
摘要:
A chamfer for securing precast concrete wall panel forms that are used in tilt-up construction. The chamfer includes an elongate base portion and at least one chamfer portion coextensive with the lengthwise direction of the elongate base portion. The base portion defines a substantially horizontal base plane. The chamfer portion includes a first leg disposed upstanding relative to the base portion, and a second leg portion angularly disposed relative the first leg. The second leg further includes at least one flexible edge that projects beyond at least the base plane or the plane defined by the lengthwise direction extension of the first leg. Depending on which part of the second leg the edge is cantilevered from, it forms a sealed relationship between the chamfer and a casting surface, the chamfer and a plank used as part of the wall form, or both. The application of weight, usually due to the addition of a plank, causes the base portion of the chamfer to flex, which in turn causes the flexible edges disposed on the chamfer outside the elastic curve defined by the flexed base portion to splay, and edges disposed on the chamfer inside the elastic curve to pinch, thereby effecting a seal to minimize or eliminate leakage associated with the poured concrete.
摘要:
Method for securing a foundation form disposed on a moisture barrier membrane. The method can include penetrating the moisture barrier membrane with one end of a stake, sealing a breach in the moisture barrier membrane around a periphery of the stake caused by the penetrating step; and removing a portion of the stake extending above the moisture barrier membrane. A sealing member can be disposed on the stake at a location along an axial length of the stake.
摘要:
A form assembly for forming a concrete structure during drying of the concrete. The form assembly is formed of an elongated plastic form having a front wall for engaging the concrete and a rear wall. The front wall is spaced apart from the back wall to define a pocket for receiving at least one connecting member. The connecting member is secured in the pocket to project a distance beyond an end of the form. A slidable stake holder may also be provided to slide in a C-shaped pocket in the form. The stake holder has right and left flanges that abuttingly engage the rear wall and at least one preformed nail hole is provided in each of the right and left flanges.
