Description

  The present invention relates to an eruption disaster prevention shelter using an arch-like structure configured using a corrugated steel material having a large section modulus such as a large deck plate, a keystone plate, or a deck plate.

  On September 27, 2014, the greatest human damage after the war occurred due to a volcanic eruption that occurred at Mt. Ontake in Gifu and Nagano prefectures. In Japan, where many volcanoes exist, it is urgent to protect mountain climbers from disasters caused by such volcanic eruptions.

  It is currently impossible to predict the occurrence of volcanic eruptions. To protect mountain climbers from eruptions, it is effective to install multiple disaster prevention shelters near mountain trails and mountain peaks. An eruption disaster prevention shelter is required to have sufficient strength to withstand volcanic ash and cinder, and a disaster prevention shelter that is compatible with the natural landscape of the mountain is required to protect the mountain landscape.

An arch-like building structure whose shelter is an openable / closable columnar arch dome using a plank seat in Patent Document 2 and reinforced with a reinforcing member in Patent Document 3 is an arch whose frontage dimension can be expanded in Patent Document 4. In Japanese Patent Application Laid-Open No. H10-260260, variable-sized buildings using large deck plates are disclosed by the present applicant.

  Such an arched building structure can reduce the manufacturing cost and greatly shorten the manufacturing period. Moreover, such a structure has sufficient strength, and can easily realize a columnar structure that can withstand stress from above and from the side as well as being a wall material and can secure a wide internal space. The arched building structure disclosed here is a relatively large-scale structure mainly used in various warehouses, factories, processing plants, etc., and a small-scale eruption disaster prevention shelter is not assumed.

  Further, Patent Literature 6 and Patent Literature 7 exist as prior documents of concrete and residential disaster prevention shelters, but concrete shelters have a high construction cost and a long construction period, and residential disaster prevention shelters have strength against cinders and the like. Cannot be secured sufficiently. Therefore, there is a demand for an eruption disaster prevention shelter that has sufficient strength, can be easily constructed in a short period of time, and can be constructed at low cost.

  First, prior to explaining a configuration example of the disaster prevention shelter, an outline of the manufacturing and installation process of the disaster prevention shelter will be briefly described. The arch-like structure assembled using corrugated steel material bent at the factory is transported to the heliport by a large vehicle, etc., and the almost completed arch-like structure is transported from the heliport to the installation place near the mountain trail and the summit. Can be lifted and transported. At the installation site, the anchor will be driven into the ground and the outside will be piled up with natural stones. Therefore, the construction cost can be reduced, and the construction period can be greatly shortened. This disaster prevention shelter is a relatively small and lightweight structure with a height of about 2m50cm to 3m40cm, a length (depth) of about 4m to 5m, and a width (frontage) of about 3m to 6m. It can be installed in the vicinity of the mountaintop.

  Embodiments of an eruption disaster prevention shelter according to the present invention (hereinafter referred to as “the present disaster prevention shelter”) will be described below with reference to FIGS. This disaster prevention shelter has two corrugated wall members obtained by bending the corrugated steel material 2 in a direction orthogonal to the corrugation direction, that is, a longitudinal direction with a predetermined curvature, and a plurality of wall members are coupled to each other. The arch-like structure 1 formed into an arch shape by connecting two wall portions 3 to each other in the longitudinal direction at the zenith portion by a connecting member 4 is used.

  As shown in FIG. 4, the disaster prevention shelter has a corrugated steel material 2 called a large deck plate having a corrugated cross section (formed with a continuous U-shaped groove) as a main structural material. The corrugated steel material is bent so as to have a predetermined curvature at least partially or entirely along a direction (longitudinal direction, groove direction) orthogonal to the corrugating direction to produce a wall member. A plurality of these wall members are connected in the wavy direction to form a wall portion 3, and the two wall portions connected to the wall members are connected to each other by welding, bolting, or other means in the vicinity of the zenith portion via the connecting member 4. To form.

  Here, the connection and connection of the wall member and the wall part are the connection between adjacent corrugated steel materials by inserting bolts into the bolt holes drilled on both side ends along the corrugated steel materials, or joining by welding. You can also The arch-like structure used in the disaster prevention shelter is a pillarless structure, and the corrugated steel material itself becomes the main structural material, so that a wide space is secured with sufficient strength.

  Natural stones, rocks, sandbags (bags filled with soil and stones) that exist on mountains, rivers, coasts, etc. in order to adapt the entire arched structure outside the disaster prevention shelter to the landscape without damaging the mountain landscape. Cover with a covering object 5 such as vegetation. The covering object can be any one of natural stones, rocks, sandbags, vegetation, and a combination thereof.

  L-shaped stoppers 6 are attached at predetermined intervals to a predetermined portion outside the wall 3 as shown in FIGS. Yes. In FIG. 2, the L-shaped stopper 6 is long and attached over the entire length of the structure, but the L-shaped stopper may be short and attached at a predetermined interval in the length direction. In FIG. 1, five are attached to one wall and four are attached to the other, but the number of L-shaped stoppers is arbitrary. The L-shaped stopper is used to prevent a covered object such as natural stone from being slid down when being stacked on the outside of the wall. It should be noted that a durable metal or plastic net (net) may be covered to prevent the covering object from sliding off, or the covering object may be stacked on the outer wall without an L-shaped stopper.

  As shown in FIGS. 1, 3 and 6, a predetermined number of anchor plates 8 having holes for inserting anchors into predetermined portions of both end portions 7 of the wall portion which is the base portion of the arch-shaped structure are welded or the like. It is joined. The arch-like structure is fixed to the ground by driving the anchor 9 into the ground GR through the anchor plate. In FIG. 3, the anchor plate 8 is attached in the vicinity of the four corners at both ends of the wall. However, the anchor plate 8 may be attached over the entire length of the structure according to the topography of the disaster prevention shelter installation site, the ground properties, etc. A plurality may be attached at predetermined intervals in the length direction. In addition, the both ends 7 of the wall part 3 make the base part of an arch-like structure.

  In the present invention, the height (length) size of any one of the wall portions 3 can be freely changed and adjusted according to the inclination angle of the ground on which the arch-like structure is installed. As shown in Fig. 1, when installing on a ground with a slope that rises to the right, the height (length) of the high side wall (right side wall in the figure) is shortened and the arch is balanced as a whole. A structured structure is constructed and installed. In this way, by changing and adjusting the height (length) size of one wall portion, the present arch-like structure can be constructed and installed even on an inclined land or a ground with a step.

  In the present invention, the base portion of the arch-like structure can be constructed by welding the anchor plate to both ends of the wall portion or by bolting with a flange fixed thereto, as shown in FIGS. H steel 11 is interposed between the both ends 7 of the steel plate and the anchor plate 8, and the end of the wall is fixed to the upper surface of the H steel by welding, bolting or other means, and the anchor is attached to the lower surface of the H steel. The plate 8 is attached by welding, bolting or other means. The H steel supports and reinforces the foundation of the arch-like structure on the ground, and the bent steel plate 12 is provided near the H-steel fixing part at the ends of both wall parts constituting the arch-like structure foundation. It can be attached to further reinforce the arched structure foundation.

  In the present invention, the length (depth) of the disaster prevention shelter can be easily accommodated by increasing or decreasing the number of connected wall members in the direction along the corrugated steel material, that is, in the width direction. If it is necessary to change the width (frontage), it is possible to easily obtain a structure having a different frontage by employing connecting members having different lengths as desired (Patent Documents 4 and 5 proposed by the present applicant). be able to. In addition, although it is set as the structure which opened the front and back part of this disaster prevention shelter in FIG.1, 7, the end wall of desired height and the door of a required dimension can be arrange | positioned as needed.

  Since the eruption disaster prevention shelter according to the present invention is constructed using corrugated steel, sufficient strength is ensured and it can be constructed at a low cost and in a short period of time. Moreover, since the outside of the arch-like structure is covered with natural stones, etc., it leads to landscape protection without damaging the mountain landscape. Furthermore, the length of one side of the wall can be adjusted freely according to the inclination angle of the ground where the arch-shaped structure is installed, so it can be installed on a sloped ground and easily corresponds to the topography of the installation location. can do.
