Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for constructing a shelter on an existing railway line or motorway, which can be constructed in a short period of time and safely.

[Conventional technology]

Figure 6 shows the conventional construction method for constructing a shelter on an existing railway line or highway. (a) is a side view of the shelter, (b) is a cross-sectional view of the shelter showing how the steel members are erected, and after the steel work is completed, the exterior of the roof, wall materials, etc. is shown in the side view of the shelter (C). A common method is to attach wood. According to this conventional construction method, a large number of members are lifted and installed on the route or road, and therefore, there is a drawback that the work time on the route or road is increased. As a result, railway or road operations may be disrupted or otherwise
If construction hours are regulated per day, there are problems such as the construction period becoming longer.For example, when construction is carried out on an existing Shinkansen line, the construction time is regulated to about 3 hours in the middle of the night. Ru.

In addition, in terms of construction safety, conventional construction methods have a high probability of accidents and disasters due to the long working hours on the route or road and the large number of parts.

[Problem that the invention seeks to solve]

When constructing a shelter on an existing railway line or highway, conventional construction methods have the problem of prolonging the construction process because the construction hours are regulated each day without interfering with railway or road operations. Ta.

In addition, with conventional construction methods, many parts are worked on the route or road, and the probability of accidents and disasters occurring is high.

The present invention was proposed to solve these problems, and provides a method for safely constructing a shelter in a short time.

[Means for solving problems]

The present invention solves the above-mentioned problems and takes the following technical measures. That is, l) The shelter is assembled in advance in the vicinity of the railway line or motorway for each lifting unit of a self-supporting member having a frame (hereinafter referred to as A unit) and a connecting member (hereinafter referred to as B unit).

? ) A plurality of A units are fixed to the foundation at regular intervals across a railway line or motorway.

3) Install B unit between each A unit.

4) In addition, a member that covers the empty space necessary for the connection work of the connecting part of A unit and B unit (hereinafter referred to as C unit)
The shelter should be integrated as much as possible, and once this is installed, the construction of the shelter will be completed.

[Effect]

The shelter will be assembled in the vicinity of the construction site where there will be no hindrance to train operation or vehicle traffic, and the shelter will be assembled in the vicinity of the construction site where there will be no hindrance to train operation or vehicle traffic, for each lifting unit: A unit that has a frame and can stand on its own, and B unit that connects this self-supporting member. In order to construct a shelter, A units are erected on the foundation at regular intervals, and these intervals are connected by B units. Therefore, a large number of A units can be erected in a short time, and the shelter can become self-sustaining. Since the A units and 1 units are connected by the B unit, the number of parts required for installation is significantly reduced, and the construction work time is significantly reduced, which shortens construction time and improves safety. The A unit is a standard type, and the B unit is designed to accommodate dimensional differences in the longitudinal direction in the case of a curved track. Installation and manufacturing errors of the A unit can also be absorbed here.

〔Example〕

Examples of the method of the present invention are shown in FIGS. 1 to 5.

Figure 1 C: x, = 1. B1 Nitsu) 2. C.L.
A perspective view of the shelter consisting of unit 3, Figure 2 is B
A perspective view of unit 2, FIG. 3 is a perspective view of C unit 3,
FIG. 4 is an assembly process diagram of the shelter, in which (a) shows the assembly status of the A unit, (b) shows the assembly status of the B unit, and (C) shows the assembly status of the C unit.

FIG. 5 shows a side view of the temporary splint for the roof panel of the B unit 2.

As is clear from the figure, the A unit 1 is composed of a frame consisting of a two-wooden main frame 5, a plurality of support beams 6 that support exterior materials, and exterior materials attached to this framework.

The B unit 2 does not have a main frame 5 and is composed of a support beam 6 that supports the exterior material, a wall panel 7 made of the exterior material, and a roof panel 8. What should be noted here is A unit 1.
The exterior material of B unit 2 is not completely attached to both ends of the support beam 6, but in order to facilitate the lifting of A unit 1 and B unit 2 and the joining work between A unit 1 and B unit 2. Part of the exterior material at both ends of the beam 6 is omitted.

C unit 3 is A unit 1. B unit) 217) This is a folded plate-shaped cover 9 to supplement the part where the exterior material is omitted, and is for finally making the exterior of the shelter continuous.

The construction procedure for the shelter is shown in the assembly process diagram in Figure 4.A units, which have been assembled and finished in advance near the construction site)1. B
Unit 2, Unit C) 3(7) First, as shown in (a), unit A is lifted onto the railway line and installed on the concrete foundation 4. After completing the installation of an appropriate number of A units 1 at equal intervals, the B unit 2 is installed between the A units 1 as shown in (b). That is, after the wall panels 7 are attached to both sides, the roof panel 8 is attached. Depending on the process, the wall panel 7 may be added later.

When lifting the roof panel 8 of the B unit 2, a temporary splint shown in FIG. 5 is used to support the weight of the B unit 2 and prevent deformation. After the installation of A unit 1 and B unit 2 is completed, C unit 3 is installed as shown in (c), completing one stage of construction.

In the embodiment, the B unit 2 is shown constructed separately into a wall panel 7 and a roof panel 8, but these may be integrated in advance and constructed at once.

〔Effect of the invention〕

For example, if the construction time per day is regulated to 3 hours using the conventional construction method, the progress of shelter construction per day will be as follows with the implementation of the method of the present invention compared to the actual value of the girder line length of 2 m (average value). h The work speed on borrowed scenery was demonstrated. In addition, work safety is increased because the frequency of work at height is reduced, and
Because the units are assembled in advance, product quality control can be ensured.
