ABSTRACT:
FIELD OF INVENTION
This invention relates to apparatus for supporting the pipes of a plumbing system during the construction of a cement building structure. More specifically, this invention relates to apparatus which is attachable at one end to a form board and at another end to a pipe in order that the position of the pipe be maintained during a concrete pouring operation.
BACKGROUND OF THE INVENTION
Methods of building construction are well known in the art in which the foundation of a building is constructed by first building a framework of form boards and then pouring concrete within the framework. Form boards are employed, in this regard, in order that the desired shape of concrete slab may be achieved. Typically when constructing such a concrete building structure it is desirable that plumbing be embedded in the concrete for various conventional reasons such as to achieve plumbing stability and space efficiency.
For this reason, various apparatus and methods have been conventionally employed in the construction art in order to provide mechanical support to a desired configuration of pipes until the concrete (e.g. for a foundation) is poured and has had sufficient time to set or harden (and thus secures the pipes in a permanent configuration). Current methods typically employed for this purpose involve driving lengths of rebar into the ground and then taping sections of pipe to the rebar in order to provide structural support to the pipe configuration. Because the rebar and tape are typically removed prior to the pouring of concrete so that footers may be dug, the pipe or pipes will often sag, and unless repositioned will result in a plumbing configuration which is permanently crooked (e.g. because it later becomes fixed in cement). Often this sagging can contribute to future pipe leaks or low water pressure (on the water side) or backfall and slow draining or stoppage (on the drain line side) and is thus highly undesirable.
One apparatus which is known in the art which is designed to support pipes before concrete is poured utilizing the stability of the form boards is disclosed in U.S. Pat. No. 5,125,619. This device is a simple single-piece bracket which can be attached at one end to the form board and at its other end to a pipe which is in need of support. The device described in this patent, however, is not capable of providing sufficient structural support in some circumstances and further, because it is not adjustable, is only capable of supporting a pipe structure if the pipe structure is located within a very small and specific range of distances from the form board which is to provide the bracket support.
In view of the above, it is apparent that there exists a need in the art for pipe support apparatus which overcomes, mitigates, or solves the above problems in the art. It is a purpose of this invention to fulfill this and other needs in the art which will become more apparent to the skilled artisan once given the following disclosure.
SUMMARY OF THE INVENTION
Generally speaking, this invention fulfills the above-described needs in the art by providing: a pipe support apparatus for supporting a pipe during the construction of a building comprising:
first means for attaching to a form board;
second means for attaching to a pipe; and
a support member extending at an angle from the first means and provided to selectively connect to the second means when the second means is attached to a pipe thereby to support a pipe in a substantially fixed position.
In a further embodiment, there is provided: a pipe support apparatus for supporting a pipe during the construction of a building comprising:
first means for attaching to a form board;
second means for attaching to a pipe;
a first support member which is connectable to the first means and pivotally connectable to the second means; and a second support member which is connectable to the first means and pivotally connectable to the second means; whereby the first support member and the second support member, when connected to the first means and to the second means, are capable of supporting a pipe in a substantially fixed position.
This invention will now be described with respect to certain embodiments thereof as illustrated in the following drawings wherein:
