Description

[0001] Cable pipe fixtures for concreting [

The present invention relates to a mechanism for fixing a pipe for a wire embedded in concrete, and more particularly, to a structure for preventing the flow of a wire from a concrete pipe to a floor of a building, The present invention relates to an electric wire pipe fixing mechanism.

When constructing a building in general, it is necessary to arrange the reinforcing bars according to the design criteria of the structure after the formwork is installed, and to expose one or more of the wire pipes (the corrugated hose) to the design position using the connectors or couplings among the arranged reinforcing bars After the concrete is laid, foundation work is completed. When the foundation work is completed, the wiring is completed by inserting the wire into the inlet of the wire pipe and connecting the electric wire exposed to the outlet to a switch or an electric box for connecting various electric devices.

Here, when arranging the wire pipes, it is necessary to fix them to the arranged reinforcing bars in order to prevent breakage or breakage. In the past, the wire pipe was bundled with a simple wire to the arranged reinforcing bars or fixed with a bent clip in a predetermined shape. However, when the concrete is poured, there is a problem that strong jetting force is applied to the wire pipe to flow. Therefore, it has been difficult to expose the wire to the correct design position due to the flow of the wire pipe, and cracks have been formed around the exposed part after curing. Above all, we had to manually tie the wire pipes, which wasted overall airships. In this way, it was necessary to plan for more stable and efficient landfill of electric wire pipes that are essential for building construction.

To solve this problem, Korean Patent Laid-Open No. 10-2008-0050824 entitled "Wiring pipe support frame" is disclosed. The disclosed document can be selectively installed in a large installation hole of a large support frame formed on the upper plate or a small installation hole of a small support frame depending on the thickness of the wiring pipe installed in the electric box, and the wiring box support frame is installed inside the mold By retaining it in the reinforcing bars, even if the concrete is injected strongly, it is possible to keep the fixed position without detaching, so that the wiring pipe can always be installed in the correct position.

However, since a plurality of supporting frames for fixing the wiring pipes are formed, waste of unnecessary materials increases the cost of the overall construction. Particularly, since the reinforcing bar hole for guiding the fitting to the reinforcing bar is formed as a simple mounting type, there is a problem that the reinforcing bar is moved or detached from the reinforcing bar during the casting process.

Korean Patent Publication No. 10-2008-0050824 "Wiring pipe support frame"

Accordingly, the present invention is intended to fundamentally solve the above-mentioned conventional problems, and it is possible to prevent the flow during installation by fitting the reinforcing bars used for fixing the wire pipe to a desired position, The present invention is intended to provide a wire pipe fixing mechanism for concrete pouring that can be implemented in a compact size while being compatible with wire pipes of various specifications, thereby reducing the cost of the overall construction.

In order to achieve the above object, the present invention provides a guide mechanism for converting a wire pipe embedded with a reinforced steel wire arranged at the bottom in a stable state into a predetermined position when exposed to concrete, comprising: at least a pair of A support plate having a support plate having an area capable of interconnecting reinforcing bars; a support having a through-hole formed on the support plate, the through-holes having a number and a size to be passed through at least one wire pipe; A plurality of mounting pieces protruding from the lower surface of the support plate at an interval that allows the reinforcing bars to be held in a state of interference with reinforcing bars, and a mounting groove formed corresponding to a diameter of the reinforcing bars accommodated between the mounting pieces; And a switching unit having a guide block having a thickness for covering the electric wire pipe on the upper surface of the support plate and a guide hole having an arbitrary number and size for allowing the electric wire pipe to pass through the guide block. do.

In this case, the fixing part according to the present invention further includes a circular mounting protrusion formed on the lower surface of the supporting plate to receive the end of the reinforcing bar by interference fit.

In addition, the fixing mechanism according to the present invention is characterized in that the fixing portion formed of a soft resin material is injection-molded integrally with the supporting portion and the fixing portion by a hard resin material, and then a switching portion formed of a soft resin material is adhered to the upper surface of the supporting portion by any one of adhesive, insert injection molding, Are mutually bonded to each other.

In addition, the fixing mechanism according to the present invention has a structure in which a plurality of mounting bosses for guiding the joining of the switching portion are integrally formed by injection molding on the upper surface of the supporting portion, And the protruding portion is protruded at a height corresponding to the height.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention relates to a guide mechanism for maintaining a stable state of a wire pipe P buried together with a reinforcing bar S arranged at the bottom when the concrete is poured, A fixing part 20, and a switching part 30 as a main component. The present invention aims at minimizing the burden on the contractor while improving the quality and workability by minimizing the cost even if some processes are added in manufacturing the fixed mechanism.

The supporting part 10 according to the present invention serves as a framework for forming the fixing part 20 and the switching part 30 and comprises a supporting plate 11 and a through hole 15 as shown in FIG. The support plate 11 is formed to have a thickness capable of stably fixing the wire P and an area capable of interconnecting a pair of reinforcing bars S arranged on the bottom. As shown in FIG. 2, the support plate 11 is formed at the center with a size and a number of through holes 15 through which at least one wire pipe P can pass. It is preferable that the through holes 15 are formed to have a size capable of passing all the at least one electric wire P having various diameters, but it is preferable that the through holes 15 are formed in plural so as to improve the durability of the support plate 11 as shown in FIG.

The fixing part 20 according to the present invention guides the mounting of the supporting plate 11 on the reinforcing bar S by one touch and comprises a plurality of mounting pieces 21 and mounting grooves 25 as shown in Fig. Loses. The mounting piece 21 is protruded at an interval at which the reinforcing bars S can be received by interference with the bottom surface of the supporting plate 11 corresponding to the reinforcing bars S. A semicircular mounting groove 25 corresponding to the diameter of the received reinforcing bars S is formed between the mounting pieces 21. That is, when the reinforcing bars S are accommodated between the mounting pieces 21, the reinforcing bars S are opened to both sides, and when the reinforcing bars S are positioned in the mounting grooves 25, the reinforcing bars S are restored as they are. Here, one end of the mounting piece 21 is formed with an inclined surface 21a that widens downward to smoothly receive the reinforcing bars S for the first time, and ribs 21b are formed on both sides of the reinforcing ribs 21 for improving returnability and durability.

At this time, the fixing part 20 according to the present invention further has a circular mounting protrusion 26 for receiving the end of the reinforcing bar S by interference fit. That is, the above-described mounting piece 21 guides the mounting to the reinforcing bars S arranged in the longitudinal and transverse directions, and the mounting projections 26 guides the mounting to the reinforcing bars S arranged in the longitudinal direction. The fitting protrusion 26 is formed with a fitting groove 26a having a diameter smaller than the diameter of the reinforcing bar S at the center. Here, the fitting groove 26a is formed such that one side thereof is opened so that the diameter becomes larger when the reinforcing bar S is received, such as the mounting piece 21. [ Accordingly, the mounting piece 21 and the mounting protrusion 26 provide compatibility with various structures.

The switching unit 30 according to the present invention switches the wire pipe P in a desired direction and comprises a guide block 31 and a guide hole 35 as shown in FIG. The guide block 31 sufficiently covers the outer surface of the electric wire P on the upper surface of the support plate 11 and has a thickness that enables stable bending in a desired direction. That is, since the reinforcing bars S arranged on the bottom are generally stacked in two stages as shown in FIG. 3, it is preferable that they have a thickness corresponding to the spacing between the first stage and the second stage. This reason will be supplemented by a description of the construction process described below.

And the guide hole 35 has the number and the size of the wire pipe P through which it can pass. Here, the guide hole 35 is shown only in a direction perpendicular to the drawing, but it can also be formed in an oblique direction according to design and field conditions. The guide holes 35 may be formed in accordance with the standard of the wire P at the time of manufacture, but it is preferable that the guide holes 35 are drilled in the field in consideration of convenience and diversity of work.

On the other hand, the fixing mechanism according to the present invention is made of a double material for minimizing the convenience of operation and manufacturing cost. That is, the support portion 10 and the fixing portion 20, which support and fix the wire pipe P to the reinforcing bar S, are formed of a hard resin material having excellent durability, The switching portion 30 is formed of a relatively inexpensive soft resin material. Therefore, it is possible to reduce manufacturing cost while improving the quality due to stable fixing of the wire pipe P, and it is possible to easily form the guide hole 35 in the field and shorten the manpower and time consumed in the work.

Since the fixing mechanism is formed of a double material, it is inevitable that some processes are added in the manufacturing process. That is, the supporting portion 10 and the fixing portion 20 are integrally injection-molded from a hard material, and at the same time, the switching portion 30 is injection molded by a soft material. After the molding is completed, they are integrally joined. Depending on the characteristics of the material and the manufacturing conditions, any one of adhesive, insert injection molding, or interference fit can be selected and joined.

The adhesive is formed by integrally bonding the guide block 31 to the upper surface of the support plate 11, which has been formed, with a bond such as silicon or epoxy. This adhesive bonding process is highly likely to cause a defect, but the cost can be reduced by simplifying the process. The insert injection molding is performed by injecting the molten soft resin material onto the upper surface of the support plate 11 after the molding of the support plate 11 is completed so that the guide block 31 is integrally joined. The injection injection molding process of inserts is limited in material application but can provide excellent quality and productivity.

Finally, the interference fit is achieved by integrally joining the guide block 31 on the upper surface of the support plate 11 by inserting. Here, it is possible that the plurality of mounting bars 40 for guiding the joining of the guide block 31 to the upper surface of the support plate 11 are further formed. That is, the mounting table 40 is protruded to a position corresponding to the position and thickness at which the guide block 31 can be sufficiently accommodated on the upper surface of the support plate 11 as shown in FIG. Such an interference fit process can reduce cost by simplifying the process, and can provide excellent quality without being restricted by the material.

Hereinafter, a construction process (embodiment) using the fixture according to the present invention will be described. First, in the construction of a building, the bottom structure is arranged in longitudinal and transverse directions at a height adjacent to the floor as shown in FIG. 3, and frame construction is carried out with first and second reinforcing bars (S) It is common to arrange the wire pipes (P) as designed between the reinforcing bars (S) after the frame construction or during the implementation. That is, a fixing mechanism may be mounted on the linearly arranged reinforcing bars S in the process of arranging the wire pipes P.

Here, as shown in FIG. 4, a guide hole 35 having a diameter through which the wire pipe P can pass is formed in order to mount the fixing mechanism. As shown in FIG. 5, the wire P passes through the through hole 15 and passes through the guide hole 35, and the reinforcing bars S corresponding to the positions to be exposed are inserted between the mounting pieces 21 and fixed by one touch. When the frame construction is completed, the floor is cured by pouring concrete as shown in FIG.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as defined by the appended claims. Accordingly, such variations or modifications should fall within the scope of the utility model registration claims of the present invention.
