1 to 5 show an embodiment of a sidewalk installation type disaster prevention shelter.
In the embodiment, as shown in FIG. 3, an earthquake occurs in a situation where there is a sidewalk 1 along the side of a building A having a certain height, such as a building, and the building A is broken from the side. This is about a sidewalk-installed shelter as a protective measure in the case where glass, peeled and broken tiles, bricks, etc. fall and attack a pedestrian on the sidewalk 1.

  From multiple points (5 points) that are close to the roadway 2 of the sidewalk 1, the pillars 3 made of square (or round) pipe made of steel, aluminum alloy, stainless steel, etc. have a height exceeding 2 m with the base part embedded. It is erected and fixed so that These pillars 3 are also erected and fixed in the same number in the same row at a position near the building A on the sidewalk 1. The column 3 on the building A side is slightly higher than that on the roadway 2 side by a few centimeters. Conversely, the roadway side is lower and rainwater can easily flow into the roadside frame 5. A roadway side frame 5 made of angle steel with a lip is mounted and fixed to the upper ends of the pillars 3 on the side of the roadway 2 with the grooves facing the building A side.

Side frames 6 and 6 are fixed from both ends of the roadside frame 5 so as to extend horizontally in the direction of the building A. The connection tool between the roadway side frame 5 and the side frame 6 is not shown.
The side frames 6 and 6 are also made of angle steel with lips, and the grooves are provided so as to face the longitudinal direction of the sidewalk 1.
On the building side of the pair of side frames 6 and 6, a building side frame 7 made of an angle groove with a lip is mounted and fixed so that the groove faces the roadway 2 side. The building side frame 7 is detachably attached to the side frame 6 by a coupling tool and a fastening tool (not shown).

  The building side frame 7 is mounted and fixed so as to pass through the upper ends of the pillars 3 for the building side frame 7 extending to the same height as the roadway side frame 5. Here, the support post 3 on the roadway 2 side and the building A side may be only one of them. The frame made up of the building side frame 7, the side frame 6 and the roadway side frame 5 is connected to the groove of the roadside frame 5 so that the lower grooves communicate with each other and the rainwater that has entered flows naturally to the roadway side frame 5 side. The route to reach is inclined low.

  Between the both side frames 6, 6, one or a plurality of receiving frames 8 are passed in a shape parallel to the longitudinal direction of the sidewalk 1. Reference numeral 10 denotes a light-transmitting, rain-proof, flat rectangular plate-shaped polycarbonate protective roof, and the roof 10 is placed in a square frame formed by the roadway side frame 5, the building side frame 7 and the pair of side frames 6. It has a suitable size, and is elastically supported by a fastening device 14 via a short bullet support rubber 12 provided on the roadway side frame 5 and a long bullet support rubber 13 provided on the building side frame 7 side. . Between the width of the protective roof 10 is elastically supported by an intermediate elastic rubber 15 and a fastening tool 14 provided on the receiving frame 8. The elastic support rubbers 12, 13, and 15 can be formed into a cylindrical body that is easily deformed as shown in a cross section in FIG.

Since the protective roof 10 is supported by the short bullet support rubber 12 so as to be low on the roadway side and slightly high on the building side by the long bullet support rubber 13, the rainwater falling on the roof is in the right direction in FIG. It is led into the roadway side frame 5. The rainwater is removed through a drain pipe 16 that communicates therewith.
The protective roof 10 is translucent, but may be non-translucent. The protective roof 10 may use other materials such as a resin other than polycarbonate, a lightweight metal such as an aluminum alloy, and a thin rubber sheet. Fiber reinforced plastics such as carbon fiber are also included here. These can be applied to the following embodiments. Further, as shown in FIG. 5, a water shielding means 17 such as caulking is provided between the outer peripheral edge of the protective roof 10 and the building side frame 7 and the side frame 6 side so that rainwater does not spill downward. You may give it.

  On the outer peripheries of the frames 5, 6 and 7, an angle-shaped bullet support portion (bullet support means) 20 having a width shortened to about 10 cm to 15 cm so that the upper piece is inward and an inverted L-shape is fastened. 21 is attached. The elastic support portion 20 is formed by attaching a weather-resistant synthetic rubber plate as a thin integrated angle member to a separate attachment type. A cushioning material 22 having an integral rhombus weave is attached through the elastic support portions 20..., And a pressing piece 23 and a fastening tool 24 are used for the attachment. The falling material Y acts on the cushioning material 22 as shown in FIGS. 3 and 5, but the energy is not only received by the cushioning material 22 by its own deformation but also by the bending of the elastic support portion 20 that is elastically deformed at that time. It can be received while softly cushioning. The elastic support portion 20 may be a metal such as an aluminum alloy or a thin stainless plate, or a resin-integrated molded product (including polycarbonate) in addition to rubber. 22a is a net body, 22b is an outer edge part, and 22c is an extension part to the building A side.

The cushioning material 22 includes a wide range of porous materials, such as stainless steel, copper, aluminum, galvanized iron wire or other metal wire knitted (including an expanded type), or a resin-integrated net or the like. Also, special weaves such as crimp weave and tie rod weave can be used. The cushioning material 22 may be formed into a rhombus knitted mesh as shown in the upper left side of FIG. 1 or a monolithic or knitted turtle-shaped net as shown on the right side. Fiber reinforced plastics such as carbon fiber are also included here. In these cases, the mesh side length or inscribed circle diameter of one mesh (eyes) is set to 30 to 50 mm so as to surely absorb and catch most of fallen objects. The above can be applied to the following embodiments.
In addition, as shown in FIG. 2, it connects with the rain gutter 26 between the adjacent disaster prevention shelters so that it may not rain.
Further, as shown in FIG. 1, the cushioning material 22 may be configured to be divided into a total of three sheets, for example, a longitudinal center one sheet “a” and front and rear one sheet “b”. Of course, the number of divisions may be two, four or five. When divided, even if each cushioning material a, b... Is damaged by a fallen object, it is only necessary to replace or maintain the damaged one, and it becomes easy to individually perform elastic deformation due to the fallen object. The divided adjacent portions are abutted or overlapped and connected to each other with a band-length connecting material.
As shown in FIG. 3, the front auxiliary cushioning material 27... Is detachably attached to the upper surface of the cushioning material 22 so as to have a partial arc shape, a semicircular shape, and a round cylindrical shape. It can be attached to to increase the buffer effect. The installation direction may be orthogonal to the direction of FIG. This can be applied to the following embodiments.
As shown in the upper side of the right column in FIG. 4, the cushioning material 22 may be a net-like one integrally formed with a circular or square expansion ring c at the intersection of the net unit main body 22a, or as shown on the lower side of the right column. Further, each side portion of the net portion main body 22a is provided with a round or square expansion ring d, and the buffer material 22 itself expands and contracts with respect to the fallen object Y, thereby effectively exerting a buffering action. You may do it. This can also be applied to the embodiments described later. Even if the cushioning material 22 is attached to each of the frames 5, 6, and 7 without the elastic support portion 20, a sufficiently large cushioning effect can be exhibited. As shown in the lower right side of the right column in FIG. 4, the net body can be formed by arranging a large number of expansion rings e. Since the cushioning material shown in the right column of FIG. 4 itself has a large elastic deformation, it may be fixed to the frame with a hook or the like without attaching a bullet support portion.

  FIG. 6 is a cross-sectional view showing a sidewalk installation type disaster prevention shelter according to another embodiment. This disaster shelter has a support roof 10, elastic rubbers 12, 13, 15 and a receiving frame in addition to the structure of the support 3, the roadway side frame 5, the side frame 6, and the building side frame 7 as shown in FIG. 8. The same applies to the fasteners 14 and the like, so the same reference numerals as in FIG.

  The elastic support portion (elastic support means) 30 is formed as a mounting plate piece by being bent with stainless steel, steel, aluminum, resin, rubber material, or the like, which can be elastically deformed as a whole. The lower side portion 30a, upper side portion 30b, elastic The lower side portion 30a is mounted on the side frame 6 in parallel and attached by the fastening tool 31, while the elastic deformation portion 30c is from the roadway side to the building side (or vice versa). The upper piece 30b becomes horizontal at a height of about 5 to 10 cm above the lower side 30a, and the fastening member 31 is interposed on the bottom surface of the cushioning material mounting frame 32 having a rectangular frame. Attached. The elastic support portion 30 may be formed of a net-like molded plate, a perforated plate, an expanded material, or the like.

For example, three of these elastic support portions 30 are arranged on one side frame 6 and three on the other side frame 6, and all of them are arranged toward only one side like the building side or the roadway side. Since it is not provided on the other frames 5 and 7, when the fallen object Y from above falls on the cushioning material 33, the cushioning material 33 first receives it with a cushioning action, and then, as indicated by the arrow. The elastic deformation part 30c of the elastic support part 30 is elastically deformed via the shock-absorbing material mounting frame 32, so that the falling energy can be received gently with a buffering action. Reference numeral 34 denotes an auxiliary cushioning material, which is attached to the building-side frame 7 of the disaster prevention shelter and protrudes toward the building A side so as to receive a thing falling near the building A and walk below. Try to protect people. If the bullet support 30 is provided not on the side frame 6 but on the frames 5 and 7 so as to stand up diagonally to the opposite side in FIG. The shock absorbing material 33 acts as a shock absorber while falling to the opposite side or the near side in FIG. In this case, as shown in FIG. 6, the elastic support 30 that rises obliquely in the width direction of the disaster prevention shelter is not provided because it inhibits the elastic deformation of the elastic support 30 that faces the longitudinal direction of the disaster prevention shelter.
As shown in FIG. 7, the auxiliary cushioning material 34 may be integrally projected from the cushioning material 33 provided on the bottom surface of the cushioning material mounting frame 32. Further, reference numeral 35 in FIG. 7 denotes a stopper that restricts upward deformation of the bullet support 30.

The rhombus in FIG. 30 is a square rotated by 45 degrees (strictly speaking, the valley of the mountain shape is 85 degrees), but may be a vertically long form b or a horizontally long form c as shown in the left column of FIG. is there. When the outer frame 103 is omitted, the elastic support portion 100A can be hooked on the end portion of the cushioning material 102 as shown in FIG. 30, or can be hooked on the crossing portion like 100B shown in the right column. This crossing part is in a relationship where the character parts are separated from each other, and the tip of the bullet support part (bullet support means) 100B enters and gets caught between them, so that the rhombus part extends and deforms by the force of the falling object In this case, the intersecting portion functions to be elastically deformed in the direction of the arrow X to increase the buffering action. As shown in FIG. 30, the outer frame 103 is not an end of the cushioning material 102, but an outer frame 103A arranged away from the outer periphery of the frame so that the outer end of the elastic support portion 100A is hooked on the cushioning material 102 side. It may be. The elastic deformation of the buffer material 102 can be obtained more greatly.

  32 and 33 show another embodiment. The cushioning material 106 extends to the side of the building A so as to prevent it from passing through the shelter and the building A and falling into the shelter. The other end of the support member 107 is stretched on the frame side of the U-shaped overhanging frame 108 that extends and is fixed to the building A side of the frame 7. The cushioning material 106 is pulled in the left-right direction in FIG. 32 and brought into a relaxed state in which the intersection is expanded and separated as shown in the right column of FIG. Thus, the elastic deformation of the cushioning material 106 itself due to the falling object is effectively made. At the same time, the elastic support 107 is elastically deformed and exhibits a buffering action. The side edge of the cushioning material 106 is not hung on the overhanging frame 108, and the buffer material 106 is elastically deformed more freely without the resistance of the side due to the force Y of the fallen object. May be. If the tip of the elastic support portion is hung in the intersection as shown by 107A in FIG. 32, not only can the intersection be kept in an expanded state, but also the buffering action in the direction of shrinking the intersection in the opposite direction can be ensured. It will be obtained. The elastic support 107 may be a coil spring type as shown in the left column of FIG.

34 and 35 show another embodiment. In this embodiment, the crossed portion of the angled wave-shaped cushioning material 111 is greatly expanded so as to exhibit a high cushioning action. The buffer material 111 has a mesh width w and a radius of the round crossing portion r, where r≈w / 3, and the crossing width c is about 0.6r. In FIG. 36, when r≈w / 3 and c≈r, as a larger intersection, a high buffering action is obtained by elastic deformation due to the deviation of the intersection. Reference numeral 112 denotes an outer frame.
The cushioning material 113 in FIG. 37 has a sinusoidal line in a braid and is hung on the outer frame 114, and the buffer 115 in FIG. 38 has a sinusoidal streak in a semicircle as a braid. It is hung on the outer frame 116. The cushioning material 117 in FIG. 39 has a U-shaped serpentine wave shape and is hung on the outer frame 118, and the cushioning material 119 in FIG. 40 has a V-shaped serpentine wave shape and is hung on the outer frame 120. It has been. The outer frames 112 to 120 in FIGS. 34 to 40 may be omitted, and the shock absorbing material 107 as shown in FIG.

  41 to 43 show another embodiment. The main part of the disaster prevention shelter is provided with the four-side frame-like frames 5, 6, and 7 on the plurality of pillars 3 as described above, and the protective roof 10 is stretched. In this embodiment, A receiving plate 123 is raised on the frames 5 and 7 of the main body so as to face each other, and a plurality of through rods 124 are mounted in parallel between the receiving plates 123, and a net is formed around each through rod 124. It is equipped with a cushioning material 125. Since the adjacent through-rods 124 and 124 are arranged in a slightly stepped manner in the vertical direction, the cushioning materials 125 and 125 are installed above the protective roof 10 in a lightly contacting manner with alternating height. The cushioning material 125 is made of an integral resin, metal, or the like, but an aluminum alloy, stainless steel, or the like that has a little weight in rotation absorbs the energy of the falling object Y and exhibits a buffering action. It is assumed that the cushioning materials 125 are set so that adjacent ones are lightly in contact with each other in a state where they are naturally suspended from the through-rods 124, or a small circumferential gap is provided to some extent. The through-rod 124 may be a simple method in which the through-rod 124 is separately attached to the frame 7 as an L-shaped bending rod.
