Description

Pipe Fixing Device for Building Construction

The present invention relates to a building pipe fixture, and more particularly, to a building pipe fixture for fixing the pipe for installing a railing or upper support pipe for the safety of the worker during construction of the building.

In general, when building a building, floors are sequentially stacked while performing formwork, reinforcement, electrical wiring, water pipe laying, and concrete pouring. As such, in order to construct the upper part in the process of building the building, a plurality of support pipes are fixed to the floor, and the upper floor is constructed with a wood plywood or the like thereon.

In addition, in order to secure the safety of the workers during construction of the building by connecting pipes along the circumference of the building to install a safety railing.

In the related art, a metal pipe fixture is fixed to the bottom surface on which concrete is cured using a support bolt or an anchor bolt for the construction of a supporting pipe or a safety railing, and is supported by inserting and fixing a pipe through a pipe insertion hole of the pipe fixture. Dragon pipes or railings were installed.

However, the pipe fixture for installing a conventional support pipe or railing is made of a metal material, and since the diameter of the pipe insertion hole into which the pipe is inserted is made according to the diameter of the standard pipe, another pipe having a smaller diameter than the standard can be used. In this case, a gap occurs between the pipe and the pipe fixture, so that the flow of the pipe occurs and the pipe breaks out.

In this case, in the related art, a separate auxiliary fixing means is fastened to the pipe fixture to suppress the flow of the pipe, but the fastening of the fixing means is cumbersome, and it is not a complete solution for preventing the pipe flow.

In addition, since the conventional pipe fixture is made of metal, when the pipe fixture is to be dismantled, it is necessary to loosen the anchor bolts to separate the pipe fixture, or when the pipe fixture is embedded in concrete, break the concrete floor with a tool and remove the pipe fixture. It had to be dismantled, in which case it took a lot of time and effort to dismantle.

The present invention is to solve the conventional problems as described above, the object of the present invention is that the pipe is firmly fixed even if the diameter of the pipe to be hypothesized and flow does not occur, the construction pipe easy to manufacture In providing a fixture.

Another object of the present invention is to provide a construction pipe fixture that is easy to construct and easy to dismantle.

The present invention for achieving the above object, the fixing portion is fixed to the bottom surface of the building during construction of the building, the hollow cylindrical insertion hole is formed to extend upward and the pipe is inserted and fixed; It provides a building pipe fixture made of a synthetic resin material formed of a plurality of pressing pieces formed to protrude toward the inner circumferential surface of the insertion hole portion to elastically contact the outer circumferential surface of the pipe inserted into the insertion hole portion.

According to one aspect of the present invention, a plurality of crushing grooves are formed in a spiral shape on the inner circumferential surface or outer circumferential surface of the insertion hole to allow crushing to proceed during dismantling operation.

According to the present invention, since the pipe fixture is made of a synthetic resin material can be easily injection-molded pipe fixture of the inner diameter suitable for the pipe of various diameters, even if a difference occurs between the outer diameter of the pipe and the inner diameter of the insertion hole of the pipe fixture Is elastically pressed and fixed inside the insertion hole by the pressing piece, so that there is little phenomenon that the pipe flows with respect to the pipe fixture.

In addition, when the operator dismantles the pipe fixture, when the operator grabs the upper end of the insertion hole with a dedicated tool and applies a force upward, the insertion hole is easily crushed in a spiral while the fracture proceeds in the crushing groove, which is relatively thinner than other parts. . Therefore, the dismantling work of the pipe fixture is made very easy.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the building pipe fixture according to the present invention.

1 to 4 show an embodiment of a building pipe fixture according to the present invention, the pipe fixture 100 of the present invention is a fixing part 110 is fixed to the bottom surface (B) of the building during construction of the building and The hollow cylindrical insertion hole part 120 is formed to extend upwardly on the fixing part 110 and is inserted into and fixed to the pipe P, and the insertion hole part 120 is formed to protrude toward the inner circumferential surface of the insertion hole part 120. It is composed of a plurality of pressing pieces 130 to elastically contact the outer peripheral surface of the pipe (P) to be inserted into.

In addition, the pipe fixture 100 of the present invention is integrally injection molded using a synthetic resin such as PVC material. Therefore, the insertion hole parts 120 having various internal diameters corresponding to the external diameters of the various pipes can be easily formed.

The pipe fixture 100 is fixed to the fixing part 110 before the concrete is placed on the floor of the building bolts, nails, screws, etc., the whole or part is embedded in the concrete.

A plurality of fastening holes 111 are formed in each corner portion of the fixing part 110 to fix the fixing part 110 to the floor of the building.

On the other hand, on the outer circumferential surface of the insertion hole 120, a plurality of crushing grooves 141 are formed in a spiral to facilitate crushing during dismantling operation. In this embodiment, the two crushing grooves 141 are formed with a phase difference of 180 degrees. In addition, protrusions 142 are formed at an upper end of the insertion hole 120 to be easily gripped by a crushing tool at a position corresponding to the pair of crushing grooves 141. As in this embodiment, the reason why the plurality of protrusions 142 and the crushing grooves 141 are formed is that any one of the protrusions 142 is formed in a wall or other structure when the pipe fixture 100 is embedded in the concrete of the bottom surface. In order to be able to crush the pipe fixture 100 by holding the other protrusions 142 with a tool even if a situation occurs that is blocked or interfered by the tool.

The pressing piece 130 is made of a structure that is cut into the approximately 'U' shape in the insertion hole portion 120 to protrude into the inner circumferential surface of the insertion hole portion 120, but may be made in various forms. In addition, in this embodiment, four pressing pieces 130 are arranged at intervals of 90 degrees on the upper and lower portions of the insertion hole 120, and a total of eight pieces are provided, but the arrangement and number of the pressing pieces 130 are necessary. It may be changed in various ways.

Pipe fixture 100 of the present invention configured as described above acts as follows.

In the building construction process, the pipe fixture 100 is seated on the bottom surface of the concrete before casting, and the fixing part 110 of the pipe fixture 100 is fixed with bolts, nails, screws, or the like. Subsequently, when the concrete C is poured into the building bottom surface to cure, the pipe fixture 100 is embedded in the concrete C and firmly fixed as shown in FIG. 3. At this time, since the pipe fixture 100 is made of a synthetic resin material such as PVC, the outer surface of the concrete (C) and the pipe fixture 100 is not completely bonded.

When the pipe fixture 100 is embedded and fixed in the concrete (C) as described above, the worker inserts the pipe through the top opening of the insertion hole 120 of the pipe fixture 100. At this time, the pressing piece 130 formed in the insertion hole 120 is elastically in close contact with the outer circumferential surface of the pipe (P) so that the pipe (P) is firmly fixed without flowing in the hollow portion of the insertion hole (120). .

Of course, in this embodiment, the pipe (P) is fixed only by the plurality of pressing pieces 130 in a state of being inserted into the insertion hole 120, unlike the pipe (P) by forming a separate clamp device or fastening device It may be to be more firmly fixed to the pipe fixture (100).

On the other hand, during the construction by inserting the pipe (P) to the pipe fixture 100 as described above to install the railings, if you want to disassemble the railings for reasons such as completion of construction, the worker grasps the pipe (P) in the axial direction When the force is applied upward, the pipe P is simply removed from the insertion hole 120 of the pipe fixture 100 and separated.

Subsequently, as shown in FIG. 4, the worker grasps any one of the protrusions 142 of the upper end of the insertion hole 120 by using a tool such as a pliers, and pulls upwards to break along the crushing groove 141. As the insertion hole 120 is crushed in a spiral. Therefore, the dismantling work of the pipe fixture 100 can be made very easily and quickly.
