Description

[Detailed Description of the Invention] The present invention is a straddle type monorail & 4M road girder in which a concave groove is formed along the intersection corner of the top surface and side surface of the four girders, and an adhesive is applied to the inner surface of the groove. Then, a non-magnetic structure supporting piping in the direction of the intersection of both surfaces is inserted into the groove at the intersection corner of the top surface and the side surface y, and the structure is placed inside the groove with the supporting force of the adhesive. piping construction for an automatic train control device, characterized in that the above-mentioned upper surface and side surfaces of the structure are aligned with the upper surface and side surfaces of the above-mentioned channel girder, and the adhesive is cured at A. It is about law.

An automatic train control device (AT) is installed on the steel road girder of the straddle type monorail.
When fixing the ATC piping, use the ATC hard Jp. PVC pipes were arranged, the pipe body holding members were welded to steel girders, and G fat monorethane was poured into the remaining space of the groove, but this method had the following drawbacks.

That is, as a result of arranging the tubular body in a part of the corner, it was necessary to use a formwork to improve finishing accuracy when casting the resin monolith. In addition, due to the use of formwork, it is not possible to check the degree of filling of the monometal, resulting in unevenness of the finished product, and the inability to follow the deflection of the ship channel due to differences in the weight and coefficient of thermal expansion of the monorail, resulting in cracking forces in the monometal. There were gaps between the shaft and the girder.

Furthermore, once the concrete is poured, it is completely adhesively fixed to the girder, which has the disadvantage of causing accidents such as damage and having to take out the bore and replace it to avoid repairs.

The present invention solves these problems by manufacturing a structure containing pipe materials for automatic train control equipment in a factory and inserting them on site so that it can follow the expansion, contraction, and deflection of the Q-way girder. The purpose is to

In order to solve this technical section JV problem, in the present invention, stud dowels are installed in the grooves in some corners of the channel girder to facilitate the insertion of structures including pipes for automatic train control equipment and to structure the girder. This prevents the acupuncture needles from peeling off the structure by keeping the body in the dark.

Also, the structure itself is manufactured by the factory) J! / '(i'
1146, which has the advantage of less variation in quality, higher finishing accuracy, and lower cost.

To explain the embodiment of the present invention shown on the third side, the upper surface 2 and both side surfaces 3
．． A concave groove 4 is formed along the intersection line of both surfaces 2.3 at the intersection corner with 3, as shown by the solid line in FIG. on the other hand,
At the factory, a non-magnetic structure 5 is manufactured using resin mortar or the like. In this structure 5, the hard vinyl chloride pipe 8 for ATC is buried at the corner of the intersection between the upper surface 6 and one side 7 in the direction of the intersection between the same two surfaces 6.7. This structure 5
Reinforcement bars 9 shown in FIG. 2 may be buried inside the
The four parts 11 for the stud dowel 10 may be formed and placed, and the material for the one-way structure 5 may be any material that has sufficient strength to serve as a running path for the mole rail. In the present invention, the girder 1 is protected from corrosion in the groove 4, and is treated with a primer that has good adhesion to the structure 5, and furthermore, the girder 1 and the structure are coated along the inner surface of the groove 4. A putty-like adhesive 12 is applied to fill the gap with 5 (see FIG. 1). In this state, the structure 5 is inserted into the groove 4, and the structure 5 is held in the groove i by the supporting force of the putty adhesive 12. ]-shaped installation aid 13 or the like, and push the structure 5 so that its upper surface 6 and side surface 7 are aligned with the upper UiJ2 and side surface 3 of the track girder 1. At that time, the adhesive 12 is plastically deformed and maintained in an aligned state, and due to changes over time, the adhesive 12 remains in that state.
It does not mean that they are on the same plane; they may be arranged in an orderly manner. In this fixed state, the elastic sealing 14 is applied and the work is completed.

Since the present invention is based on the construction method described above, it is possible to quickly install the automatic train rail 1j control device ladle arrangement R/8 at the intersection corner between the upper surface 2 of the plow 4ilE road girder 1 and both sides...13.3 of the straddle type mole rail. It can be constructed in a ceremonial manner, is suitable for childbirth, and not only can the construction efficiency be improved, but also can eliminate the above-mentioned defects and exhibit the above-mentioned advantages.
