Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an arch type shelter constructed mainly for roads, railways and the like in preparation for avalanches and landslides.

[0002]

2. Description of the Related Art Generally, a shelter may be constructed on roads, railways, etc. running in mountainous areas in preparation for avalanches and landslides, but most of them are constructed by cast-in-place concrete.

[0003]

However, since a shelter made of cast-in-place concrete requires a large amount of manpower and materials, temporary mountain scaffolding is likely to be unstable in safe construction in mountainous areas where traffic is inconvenient. Not only is there a problem in terms of aspects, but it is difficult to transport materials, and the construction period is unavoidable, and the construction cost is likely to increase.

The present invention has been made to solve the above-mentioned conventional problems, and provides an arch-type shelter which can be easily constructed in preparation for an avalanche or a landslide on a road or railway. With the goal.

[0005]

In the arch-type shelter according to the present invention, a plurality of floor plates having recesses at both left and right ends are laid so that the recesses are continuous in the continuous direction of the arch-type shelter, and the peripheral edge is provided. Having a reinforcing rib, a plurality of curved plate-shaped segments are placed on the floor plate, one of the reinforcing ribs is erected in the recess, and the other of the reinforcing ribs is abutted and installed in an arch shape, The reinforcing ribs are fixed to the recesses by a plurality of anchor bolts, and the other reinforcing ribs are used as a notch joint, and the reinforcing ribs are joined by a plurality of joining bolts. ing.

[0006]

1 to 3 show an embodiment of an arch-type shelter according to the present invention. In the drawings, reference numeral 1 is a segment for constructing the arch-type shelter, and 2 is a segment for mounting the segment 1. It is a floorboard of.

The segment 1 is formed in a rectangular curved plate shape having a predetermined curvature according to the scale of the arch-type shelter to be constructed, and a reinforcing rib 1a is continuously formed in the circumferential direction on the peripheral portion thereof. ing. In addition, connecting bolts 3 for connecting the opposing segments 1 to the reinforcing ribs 1a on each side.
Also, bolt holes 1b through which anchor bolts 4 for fixing the segment 1 to the floor plate 2 are formed are formed at predetermined intervals.

The floor plate 2 is formed in a rectangular plate shape having a predetermined size according to the scale of the arch-type shelter constructed similarly to the segment 1, and the left and right ends of the floor plate 2 in the circumferential direction of the shelter. Recesses 2a, 2a for forming one reinforcing rib 1a of the opposing right and left segments 1 are formed.

The floor plate 2 is laid so that the left and right recesses 2a, 2a are abutted in the continuous direction of the shelter so as to be continuous in the continuous direction of the shelter, and a plurality of segments 1 are arched on the floor plate 2. It is installed in a shape. At that time, the reinforcing ribs 1a on the lower end side of the segments 1, 1 facing each other in the circumferential direction of the shelter are erected in the recess 2a and are anchored by the anchor bolts 4 penetrating the bolt holes 1b into the recess 2a. Reinforced rib 1a firmly fixed and on the upper end side
Are butted at the center of the arch and joined by a plurality of joining bolts 3 penetrating the bolt hole 1b.

Further, the reinforcing ribs 1a, 1a of the segments 1, 1 facing in the continuous direction of the shelter are joined by a plurality of joining bolts 3 penetrating the bolt holes 1b.

The segment 1 and the floor plate 2 are precast concrete plates that can be mass-produced by reinforced concrete, but it goes without saying that they may be steel segments.

Further, a sealing material (not shown) is filled in the joint between the opposing reinforcing ribs 1a, 1a to prevent rainwater from entering.

FIGS. 4 (a) and 4 (b) show another embodiment of the arch-type shelter according to the present invention. In the embodiment of FIG. 4 (a), the shelter is opposed to the circumferential direction. Segments 1 and 1 are installed staggered in the continuous direction of the shelter,
In the embodiment shown in FIG. 4 (b), the segments 1 and 1 which are also circumferentially opposed to each other are joined by a so-called phased joint, both of which are intended to increase the joint strength between the segments. Is. The other structure is exactly the same as that of the above embodiment.

[0014]

The arch-type shelter according to the present invention is constructed as described above, and a plurality of floor plates having recesses at the left and right ends are laid so that the recesses are continuous in the continuous direction of the arch-type shelter. A plurality of curved plate-shaped segments, each having a reinforcing rib on its peripheral edge, are placed on the floor plate, one of the reinforcing ribs is set up in the recess, and the other of the reinforcing ribs is abutted to be installed in an arch shape. Then, one of the reinforcing ribs is fixed to the recess by a plurality of anchor bolts, and the other of the reinforcing ribs is an intermittent joint, and the reinforcing ribs are joined by a plurality of joining bolts. Therefore, the segments can be securely fixed in place, the segments can be securely joined together, and the road surface can be constructed simply by laying a floor plate. The roads and arched shelter constructed railway is readily constructed can effectively.
