DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pipe end fixing member, and more particularly to a pipe end fixing member used for indoor wiring work of a building and the like. In a wiring structure that allows wires such as electric wires to pass through this pipe, it is a member for fixing the end of the pipe to the mold when casting concrete, and after the concrete is cast, The present invention relates to a piping terminal fixing member capable of drawing out a wiring passed through from a terminal.

[0002]

2. Description of the Related Art Conventionally, when embedding an electric conduit in a concrete structure, the end of the electric conduit is fixed to a concrete casting form. Therefore, the end of the conduit is connected and fixed to a pipe joint of a fixing member made of metal or the like, and the fixing member is fixed to the formwork with bolts or nails. After the concrete is cast, the electric wire passed through the conduit is drawn out from the opening of the fixing member exposed on the surface of the concrete structure, and wiring is performed indoors.

FIGS. 7 (a) and 7 (b) show an example of the structure of a conventional pipe end fixing member for a conduit, and a pipe joint portion 1 for connecting and fixing the conduit, and an electric wire passed through the conduit. And a notch that is not shown but is opened at the bottom surface of the housing portion 2, and a nail for fixing a fixing member to a mold or the like is provided on an outer peripheral edge of the housing portion 2. A fixing portion 4 provided with a through hole through which a bolt and a bolt pass is provided. Fig. 7 (a)
As shown in FIG. 7 (b), there is a case where only one pipe joint portion 1 is provided, and a case where two pipe joint portions 1 are provided symmetrically as shown in FIG. When attaching the fixing member to the formwork,
It is necessary that the opening 3 of the fixing member be brought into contact with the surface of the formwork so that concrete does not enter the housing 2 from the opening 3. Therefore, the fixing portion 4 is usually provided on both side surfaces of the fixing member or on an end surface on which the pipe joint portion 1 is not provided.
The fixing member is provided at a plurality of locations so as to surround the entire circumference.

[0004]

However, in the structure of the conventional pipe end fixing member of the conduit described above,
There is a problem that handling in transportation and storage is troublesome. It is very troublesome to transport and store the number of fixing members required for the construction in a disjointed state, and there is a possibility that the fixing members may collide with each other and be damaged or deformed during transportation and storage.

As another problem, there is also a problem that the concrete easily enters through a gap between the formwork and the opening 3 when the concrete is poured. This is because, simply by pressing the opening 3 against the form and fixing it with the fixing parts 4 at a plurality of places, when a concrete placing pressure or the like is applied, the form 3 is interposed between the fixing parts 4 and the like. There is a gap between the openings 3 and it is impossible to prevent concrete from entering. Usually, the formwork is made of plywood or the like, and it is impossible to keep the opening 3 in close contact with the formwork, and the formwork or the fixing member is deformed when the concrete placing pressure or the like is applied. Therefore, a gap is generated.

Further, if a fixing portion is provided on the side surface of the fixing member to fix the fixing member to the mold, the fixing portion protruding from the side surface of the fixing member when a plurality of fixing members are to be arranged side by side. There is also a problem in that the space between the fixing members is widened and the construction space is required. Since a nail is driven into the fixing portion or a bolt is screwed into the fixing portion, the distance between the fixing members must be considerably large in order to insert a tool for the operation and perform the operation. If the fixing members on the side surfaces are eliminated in order to install the fixing members without gaps, the intrusion of the concrete described above becomes excessively severe.

[0007] The above-mentioned problems occur not only in the construction of power wiring but also in the construction of communication lines, optical fibers and other wiring. In view of the above, an object of the present invention is to provide a pipe terminal fixing member as described above, which can be easily transported and stored, can reliably prevent intrusion of concrete at the time of placing concrete, and furthermore, a plurality of fixing members. It is an object of the present invention to provide a wiring terminal fixing member that can be installed efficiently by closely contacting.

The number of main bodies are separated from each other, and the accommodating portions can be juxtaposed or closely juxtaposed to each other. The individual caps are integrally connected via a separable connecting portion.

The basic structure of the main body of the pipe end fixing member may be the same as that of a normal fixing member. The material of the main body is made of a metal such as steel or aluminum or a synthetic resin, and is composed of a metal casting, a forged product, a pressed product, or a synthetic resin molded product. The pipe joint section may be provided with a normal pipe joint structure in accordance with the material, structure or use of the pipe.

[0010] The housing portion may have a rectangular parallelepiped shape, a semi-cylindrical shape, a kamaboko shape or any other shape as long as the housing portion has a cavity in which the wiring is easily handled. The accommodation section needs to have a width wider than the width of the pipe and the pipe joint section. This is because, when a plurality of main bodies are arranged side by side with the accommodating portions closely contacting each other, the piping or the pipe joint portions do not collide with each other. A fixing portion for fixing the main body to the formwork can be provided in a portion of the outer periphery of the housing portion except for both side surfaces. The fixing portion is provided with a through hole for inserting a nail or a bolt, and a structure for attaching another fixing metal.
It is preferable that both sides of the housing portion have flat and substantially vertical side walls in order to arrange the main bodies close to each other.
However, the housing portions may not be in close contact with each other, but may be in a state of being close to each other with a slight gap. An opening serving as a wiring outlet is provided on the bottom surface of the housing. The shape of the opening may be rectangular, circular, elliptical, or any other shape.

The concrete intrusion prevention cap is preferably made of a material having a certain degree of flexibility, for example, rubber or synthetic resin. The cap alone has an outer shape that is substantially the same as or slightly larger than the inner peripheral shape of the opening of the main body. Then, the opening is completely closed and the cap alone is temporarily fixed to the opening in a state where the cap alone is fitted into the inner periphery of the opening. The cap alone may be provided with an engagement means capable of engaging within the opening of the main body. Specifically, irregularities and the like which can be engaged with each other can be provided inside the housing portion of the main body and on the upper surface of the cap alone.

The connecting portion connects a plurality of caps alone and connects them integrally. The shape of the connecting part is a narrow tongue, etc., so that the caps can be integrated so that they do not fall apart, and if necessary, the connecting part can be cut or folded to separate the caps. Keep them separate. For this purpose, the thickness of the connecting portion can be made smaller than that of the cap alone, or a V-shaped groove or constriction for separation can be provided. If the entire cap, that is, the plurality of caps alone and the connecting portion are integrally formed, manufacturing is easy. When the cap unit connected by the connecting unit is fitted into the opening of the main body, if the recess or notch corresponding to the connecting unit is formed in the opening of the main unit, the connecting unit does not interfere and the cap unit Can be completely inserted into the opening of the main body.

The piping terminal fixing member according to the present invention can be freely applied to ordinary piping work as long as it is a construction structure in which a pipe is embedded in a concrete structure such as an indoor wiring of a building and the wiring is passed through the inside. . Specifically, the present invention can be applied not only to power wiring, but also to wiring for communication wires and optical fibers.

[0014]

When a concrete cap for preventing concrete intrusion is fitted into the opening of the housing portion of the fixing member main body having the pipe joint portion and the housing portion, when the concrete is poured, the concrete can be inserted through the opening. There is no fear of intrusion.
If the opening can be closed with such a cap alone, it is possible to reliably prevent concrete from entering without having to provide a large number of fixing parts for nailing or bolt insertion all around the accommodating part. it can. If it is not necessary to provide a fixing portion on the side surface of the housing portion, the housing portions of the main body can be arranged in a state where they are closely or very close to each other. It becomes possible to install well.

[0015] If a plurality of caps are integrally connected at the connecting portion to form a cap for preventing concrete intrusion, the cap and the cap are fitted and fitted with the opening of the main body in each cap alone. A plurality of main bodies can be handled collectively in an integrated state. Therefore, when transporting and storing the fixing members, a large number of fixing members can be handled simply and efficiently collectively.

The required number of caps and the fixing member main body can be separated by cutting or folding the connecting portion, so that the fixing member can be easily sold or divided and used. Furthermore, after placing concrete,
