Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a joining structure of a shelter using a deck plate, and more particularly to a joining structure of a shelter using a deck plate that can be easily joined.

[Prior Art] For example, in order to ensure the safety of a road in a snowy area or an avalanche area, a shelter installed on the road has a large static vertical The load P or a large unbalanced load P due to snow pressure acts on the shelter 1 as shown in FIG.

Conventionally, as a shelter having high strength, one shown in FIG. 6 has been proposed. The shelter 1 comprises deck plates 1A bent in the corrugation direction (A) and joined to each other in a semi-cylindrical shape.

In the shelter 1, the deck plates 1A are joined to each other by bolting the joining plate 2 closely attached to the deck plate 1A as shown in FIG.

[Problems to be Solved by the Invention] However, the conventional joining structure of the shelter using the deck plate described above has the following problems. That is, the joining plate 2 causes the deck plate 1A
Put the hands inside the shelter 1 so that the bolts 3 do not come out of the deck plate 1A when joining the
It was necessary to hold the bolt 3 by hand and tighten the bolt 3.

Therefore, an object of the present invention is to provide a shelter joining structure using a deck plate, which facilitates joining work.

[Means for solving the problem]

This invention relates to a joining structure of a shelter using a deck plate for constructing a semi-cylindrical shelter by connecting the circumferential ends of the deck plates bent in the corrugation direction to each other. The end plate is fixed at a right angle to the circumferential end of the deck plate, and the end plates are fixed to each other by bolts.

Next, a joint structure of a shelter using a deck plate of one embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a front view showing a joint structure of a shelter using a deck plate according to an embodiment of the present invention, FIG. 2 is a sectional view taken along the line AA of FIG. 1, and FIG. It is the A direction view of a figure.

As shown in FIG. 1 to FIG. 3, the joining structure of the shelter using the deck plate of the present invention has a structure in which the circumferential end portion of the deck plate 1A bent in the corrugation direction is
The end plate 4 is fixed at a right angle, and the end plate 4
Are fixed to each other by bolts 5.

In this way, by joining the deck plates 1A bent in the corrugating direction to each other through the end plates 4 fixed to the circumferential end portions, the joining operation of the shelter 1 can be easily performed. That is, since the bolt 5 is horizontally inserted into the end plate 4 when the deck plate 1A is joined, there is no risk that the bolt 5 will fall out of the deck plate 1A. Therefore, as in the conventional case, put the hand inside the shelter so that the bolt 3 does not come out of the deck plate 1A, and while holding the bolt 3 by hand, the bolt 3
No need to tighten. Moreover, the error in the manufacturing and construction in the circumferential direction of the shelter is between the two end plates.
This can be easily performed by sandwiching an auxiliary plate described later. Further, the joint strength between the deck plates can be improved by the plate thickness of the end plates and the bolt position. Further, in the structure constructed by the arc-shaped deck plate, since the rigidity in the girder direction is smaller than the rigidity in the arc direction, it is necessary to disperse the concentrated load in the girder direction as much as possible. Since the end plate acts as a connecting beam for this purpose, the strength of the entire shelter is increased.

As shown in FIG. 3, in order to prevent water from entering the shelter 1 from the joint portion of the deck plate 1A, the ridge board 6 may be fixed together with the bolt 5 on the upper portion of the joint portion. Good.

Further, as shown in FIG. 4, if the auxiliary plates 7 are sandwiched between the end plates 4, one of the adjacent deck plates can be temporarily fixed, so that the assembling of the shelter becomes easier.

Furthermore, when installing lighting and ventilation equipment in the shelter, the end plate can be used.

[Effect of device]

As described above, according to the present invention, the joining work of the shelter is facilitated by joining the deck plates bent in the corrugating direction to each other via the end plates fixed to the circumferential end portions. It has an extremely useful effect of being able to do.
