Abstract
A footing liner is provided to preserve and maintain the design of a footing dug in ground in accordance with the engineering and architectural specifications. The liner for footing is disposable inside the trench for receiving concrete slurry, when set forming a concrete footing forms inside the liner. The liner comprises a channel and a pair of upwardly extending walls connected to the channel for holding the slurry therein. One of the walls includes a sloping portion, which extends inwardly of the perimeter to form a perimeter liner while an interior liner includes two sloping walls. Another embodiment of the perimeter liner is for brick veneer, steel and prefabricated buildings.
Claims19
A liner to preserve a predetermined shape and design of a concrete footing to be formed in a trench dug in a ground, said liner being disposable inside a trench for receiving slurry when set forming a concrete footing in said liner, said liner comprising a channel and a pair walls connected to said channel for holding a slurry therein.
A footing liner to preserve a predetermined shape and structure of a concrete footing to be formed inside said liner in a trench dug in a ground, said liner being disposable inside a trench for receiving concrete slurry therein, said liner forming a mold for slurry and permitting setting into a concrete footing.
A method for constructing a concrete slab for a building comprising the steps of:
- A. digging a trench for a footing in a ground around a perimeter of a building;
- B. installing a supporting frame about the trench;
- C. disposing a liner inside the trench to hold a concrete slurry;
- D. disposing reinforcing bars inside the supporting framework;
- and
- E. pouring concrete slurry inside the supporting frame including the liner and permitting the slurry to set into and form a concrete perimeter footing and a concrete slab.
In a process for constructing concrete slab of a building including digging a perimeter footing in a ground;
- installing a supporting framework about the perimeter pouring a concrete slurry inside the framework;
- a method for preserving shape and design of the concrete footing comprising the steps of:
- A. disposing a pre-formed liner conforming in shape substantially to a cross-section of the footing located inside the footing before the step of pouring in the concrete slurry, and
- B. allowing the poured concrete slurry to cure to form the concrete footing and slab.
