2. Description of the Related Art Recently, prefabricated construction work is progressing more and more. For example, in the case of an apartment house, first, a frame that can accommodate multiple dwelling units will be built, and each dwelling unit will be constructed inside this frame with a partition structure. It suffices to simply assemble the various processed materials on site according to a predetermined procedure and arrangement.

[0003] Such prefabrication has a problem of increasing the skill of dwelling unit construction workers. That is, the construction work of the dwelling unit includes various works such as installation of partition panels, installation of unit equipment, piping for water supply / drainage, air supply / exhaust, etc., and any of these various works. It is desirable for one worker to do as much as possible in terms of streamlining work. However, such multi-skilling tends to be accompanied by a relative decrease in work proficiency. Therefore, in order to effectively promote the multi-skills associated with prefabricated work, it is necessary to further standardize and simplify the work content, and to design a system and materials that enable easy and reliable construction without skilled skills. It will be.

With respect to the method that can contribute to the promotion of multi-skills in the background of such circumstances, the applicant of the present invention first applied a construction method for piping and wiring in the ceiling.
No. 64, and an indoor unit cable and its construction method were proposed as Japanese Patent Application No. 3-101783.

In the former technique, a plurality of rail members are provided on the ceiling slab so as to be parallel to each other and oblique to each side of the ceiling slab, and a supporting member is attached to the rail member. Due to the diagonal arrangement of the rail members, the pipes and wirings arranged in parallel to each side of the ceiling slab will always intersect the rail member at some position, and the support member is positioned and supported at this intersection. It is designed to be able to do.

The latter technique is disclosed in, for example, Japanese Patent Publication No. 59-154.
It is a further improvement of the prefabricated technology for indoor wiring as shown in No. 49, which enables cables to be connected to electrical equipment such as load connection ends and switches located in various places in the dwelling unit or various detectors via joint boxes. For branching / connecting, the multiple cables from the joint box are bundled together in a specific direction and led out, and the branch cables from this cable bundle to each electrical device are always branched at right angles to the cable bundle. At the same time, an instruction unit for instructing the right-angled branch point is added in advance at the factory to facilitate the wiring work.

It is an object of the present invention to provide a tip end fixing jig capable of accurately and efficiently performing the above process.

[0008]

In the tip end fixing jig according to the present invention, a plurality of fitting grooves for fixing the tip end portion of the cable into a fixed state by fitting are formed at appropriate intervals. This tip end fixing jig is used, for example, by being attached to the end of a slender working table. That is, the required number of cables is supplied from the other end of the workbench, and the cables are provided, for example, in the guide pin of the array regulation jig formed by vertically arranging a plurality of guide pins at intervals allowing the cables to pass. By inserting it between them, it is regulated to a predetermined arrangement state, that is, an arrangement state that matches the designed wiring state in advance, and the tip of each cable whose arrangement is regulated is fitted into the fitting groove of the tip fixing jig. Let it be fixed. Then, under the state of being fixed by the tip end fixing jig, the work for uncovering the cable tip end portion for adjustment for connection and other work for unitization are efficiently performed.
