Abstract

PURPOSE:To improve workability by setting up a plural number of segments, having reinforcement ribs on its circumferential portion and formed in a curved plate shape, in an arch shape as abutting them in the circumferential and orthogonal directions and also joining the reinforcement ribs of the segments facing each other. CONSTITUTION:Segments 1 are formed in a short curve plate of a specified curvature conforming to the scale of the shelter to be constructed and they are provided with continuous reinforcement rib 2a on the circumferential edge thereof in the circumferential direction. Bolt holes 1b, which are for running joining bolts 3 through to connect segments 1 facing reinforcement ribs 1a of the respective edges together and for running anchor bolts 4 through to secure segments 1 to a floor plate 2, are formed by leaving a specified space between them. The floor plate 2 is then laid as abutting it to the continuous direction of the shelter so as right and left recessed portions 2a, 2a may continue in a groove shape in the continuous direction of the shelter. Further, a plural number of segments 1 are built on the floor plate 2 in an arch shape. At this time, reinforcement ribs 1a on the lower end of the segments 1, 1 facing the circumferential direction of the shelter are erected into the recessed portion 2a and secured by means of anchor bolts 4 penetrating through bolts holes 1b. The reinforcement ribs 1a on the upper end are made to abut on each other in the center of the arch and joined together by means of the joining bolts 3.

Description

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]

An arch-type shelter according to the present invention has a plurality of segments, each having a reinforcing rib on its peripheral edge and formed in a curved plate shape, butted in a circumferential direction and a direction orthogonal thereto. While installing in an arch shape, and
It is constructed by joining reinforcing ribs of opposite segments.

[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 shelter to be constructed, and a reinforcing rib 1a is continuously formed in the circumferential direction on the peripheral portion thereof. . The reinforcing ribs 1a on each side are provided with bolt holes 1b through which joining bolts 3 for joining the opposing segments 1 and anchor bolts 4 for fixing the segments 1 to the floor plate 2 are inserted at predetermined intervals. There is.

The floor plate 2 is formed in a rectangular plate shape of a predetermined size according to the scale of the arch-shaped 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 opposed to each other in the circumferential direction of the shelter are joined by so-called notch joining, and the purpose of each is to increase the joining strength between the segments. It is a thing. The other structure is exactly the same as that of the above embodiment.

[0014]

According to the arch-type shelter according to the present invention, which is constructed as described above, a plurality of segments formed in a curved plate shape having a reinforcing rib at the peripheral edge thereof are formed. It is installed in an arch shape while facing each other and the direction orthogonal to it, and it is constructed by joining reinforcing ribs of opposite segments, so it is easy to install a shelter to avoid avalanches and cliffs on roads and railways in mountainous areas. There is an effect that can be built.
