Description

[Detailed Description of the Invention] This invention relates to a piping fixture for fixing the position of piping buried in concrete during concrete pouring.

For example, in a building, as shown in Figure 1, a pipe C for passing electric wires is buried in a wall A or a beam B, and as a means of burying it, a flange is formed in advance at the end of the pipe C. means for fixing the flange to the temporary frame by nailing it to the temporary frame.
17797) and Utility Model Application Publication No. 117898/1983, methods using an auxiliary device have been proposed.

However, the former method cannot be used for pipes without flanges at the pipe ends, and requires time and effort to process the pipe ends once during pipe burying work. Moreover, according to the latter method, there is a dissatisfaction that it can only be used for piping C where the nipple can be screwed onto the pipe end, and if the pipe diameter of piping C is different, other auxiliary tools must be prepared. There are problems such as the structure of the tool itself being complicated and the manufacturing cost increasing. The present invention was made for the purpose of providing a piping fixture that can solve the above-mentioned problems, and its features include an inserting body that is inserted into the end of the piping, and a plurality of fittings that are driven into a temporary frame. This is a piping fixing device comprising a main protruding nail, and the inserting body has a structure in which cylindrical bodies of different diameters are integrally formed in multiple stages according to the order of their diameter lengths and with their axes aligned. The plurality of protruding nails are configured such that their bases are embedded in the insert and are protruded from the smooth surface of the cylindrical body with the longest diameter parallel to the axis of the cylindrical body. be. DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to FIG. 2 and subsequent drawings showing embodiments of the present invention.

Fig. 2 is a perspective view showing one embodiment of the present invention;
The figure shows a longitudinal sectional view of the same.

In the figure, 1 is an insertion body that is inserted into the end of the pipe C,
2 shows a plurality of protruding nails to be driven into the temporary frame D.

Specifically, the insertion body 1 is formed by integral molding from a resin material, and includes cylindrical bodies 3a of different diameters,
3b, 3c, and 3d are arranged in the order of their respective diameter lengths and with their respective axes coincident, and the side of the cylindrical body 3d of the smallest diameter of the insertion body 1 is the insertion side into the tube end. Therefore, the side of the cylindrical body 3a with the largest diameter becomes the side fixed to the temporary frame D.

Further, the protruding nail 2 has its base embedded in the insertion body 1, its protruding position is set on the smooth surface 4 of the cylindrical body 3a with the largest diameter, and its protruding direction is set parallel to the axis of the cylindrical bodies 3a to 3d. The plurality of protruding nails 2 are embedded when the insert 1 is molded. In addition, 5 is a lip portion formed integrally with the inserting body 1 and formed to protrude in the same direction as the protruding direction of the protruding nail 2 so as to extend the circumferential surface of the cylindrical body 3a to the edge of the smooth surface 4. , the lip portion 5 plays the role of preventing slag from entering the concrete E when the piping fixture is used.

The piping fixture of the present invention as exemplified above is the fourth
Use as shown in Figure A or Figure 4 B.

FIG. 4A shows an example of use when only the pipe C is buried, and the protruding nails 2 are nailed into a certain position of the temporary frame D so that the insertion body 1 is attached to the specified position of the temporary frame D. Next, the pipe end of the pipe C to be buried is fitted onto the inserting body 1 to fix the pipe C in position. In addition, when attaching the connecting cap F to the pipe end and burying it as shown in Figure 4B, screw the connecting cap F onto the pipe end and use it in the same way as shown by the imaginary line in the figure. do. Once the pipe C is fixed in a certain position in this way, concrete E is placed inside the temporary frame D.
is cast, and after the concrete E has hardened, the temporary frame D is removed. At this time, the piping fixings of the present invention, which have been driven into the temporary frame D, are removed as one unit with the temporary frame D, and then the temporary frame D is removed. In the case of Fig. 4 A, only the pipe C is connected, and in the case of Fig. 4 B, the pipe C screwed together with the connection cap F.
will remain buried in the designated location, and the desired construction will be accomplished.

In the illustrated drawing, the number of protruding nails 2 is three, and the cylindrical bodies 3a, 3b, 3c, and 3d are formed in four stages, but these numbers can be changed as appropriate. Instead of forming the seal 5, a packing 6 may be attached to the smooth surface 4, as illustrated in FIG. Of course, the lip portion 5 or the packing 6 is not necessarily necessary, and can be omitted as appropriate depending on the type of concrete E used or the situation at the construction site.

As explained above, the present invention has a simple structure consisting of an insertion body and a protruding nail, and can be easily manufactured by integral molding using a resin material. Since the fitting body is constructed in multiple stages with cylindrical bodies with different diameters,
It can be used to fit and fix various pipes with different diameters without any pre-processing, and can also be used for pipes with screwed connection caps, as the protruding nails are accurately driven into the temporary frame. The piping is then fixed in a precise position by the insert, which is a useful device that solves all of the problems mentioned above.
