Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for mounting a panel such as a tunnel interior plate installed on an inner wall of a tunnel such as a road or a railway. 2. Description of the Related Art Generally, in a tunnel such as a road or a railway, there is an increasing demand for covering a wall surface in the tunnel with an interior plate in order to ensure safe passage of vehicles.
In addition, a construction method is known in which a wall surface after a surface water conduction treatment for a tunnel in which water leakage occurs is covered with an interior plate.
In addition, in the construction of this tunnel interior board, a plurality of tunnel interior boards are combined and constructed. [0003] However, in the above-mentioned panel mounting structure for the interior panel of the tunnel, it is difficult to absorb irregularities in the inner wall surface of the tunnel, and even if there is a slight unevenness, the panel can be mounted on the panel. There is a problem that the surface becomes uneven. Accordingly, the present inventor has conducted intensive studies in view of the conventional drawbacks, and as a result, has provided an unevenness adjusting panel mounting structure that can easily absorb irregularities on the ground surface. A non-adjustable panel mounting structure according to the present invention comprises a panel provided with a plurality of reversely threaded female screws on each of two opposing side edges, and a plurality of forwardly threaded screws on a base surface. Female screw is provided, one side surface of the base surface is bent at a substantially right angle to form a vertical surface, and the other side surface of the vertical surface is bent at a right angle to form a mounting surface, and a bolt hole is formed in the mounting surface. With a mounting bracket that was drilled,
It consists of a double screw bolt having a forward screw threaded from one end to the center and a reverse screw provided substantially from the other end to the center. The mounting bracket attached to the wall surface and the panel are screwed with the double screw bolt. The level of the panel can be easily adjusted by rotating both screw bolts after installing the panel. Hereinafter, the present invention will be described with reference to the drawings. Reference numeral 1 denotes a panel, which is made of an inorganic plate such as a calcium silicate plate as a substrate, a panel made by painting the surface, a panel made by painting or enamelling a steel plate or an aluminum plate, or a stainless steel plate. Panel is used. Plural reverse female screws 11 are provided at appropriate positions on two side edges of the panel 1. The female screw 11 of the reverse thread is formed by embedding an embedded nut at an appropriate position of the panel. Reference numeral 2 denotes a waterproof sheet, which is a synthetic resin sheet made of polyethylene, polyvinyl chloride, EVA, or the like.
And is attached to the inner wall of the tunnel with an anchor bolt 5 via a square washer 4 with a seal. The mounting bracket 3 is manufactured by bending a metal plate such as a steel plate. On one surface of the mounting bracket 3, a plurality of female screws 31 having forward threads are provided to form a base surface 32.
The side surface is bent at a substantially right angle to form an upright surface 33, and the other side surface of the upright surface 33 is bent at a substantially right angle to form a mounting surface 34, and a bolt hole 35 is formed in the mounting surface 34. .
The base surface 32 on which the female screw 31 is provided and the mounting surface 34 on which the bolt hole 35 is formed are substantially parallel surfaces, and a height difference is appropriately provided. The square washer 4 has a bolt hole formed in the center of a metal plate such as a steel plate of an appropriate size, and an elastic sheet 41 such as a rubber sheet or a sponge sheet is adhered to one surface. When the mounting bracket 3 is screwed into the anchor bolt 5 embedded in the inner wall of the tunnel, the elastic sheet sticking surface of the square washer 4 is brought into contact with the mounting bracket 3 to prevent water from entering the waterproof sheet 2. In. Reference numeral 6 denotes a double screw bolt. A forward screw 61 is screwed from one end to substantially the center, a reverse screw 62 is screwed from the other end to substantially the center, and a cross hole is formed in the end face. It is provided and is easy to turn with a driver. The forward screw and the reverse screw have the same diameter and pitch. As an example of the embodiment of the uneven panel mounting structure of the present invention, a method for installing a tunnel interior plate will be described. First, the forward screw 61 of the two screw bolts 6 is screwed into the female screw 31 of the mounting bracket 3, and the reverse screw 62 of the double screw bolt 6 of the mounting bracket 3 is inserted into the female screw 11 provided on both side edges of the panel 1.
Is screwed in and fixed. Next, the waterproof sheet 2 is temporarily fixed over the front surface of the inner wall of the tunnel, and the panel 1 having the mounting brackets 3 attached to both edges thereof is brought into contact with the waterproof sheet 2 so as to be aligned with the bolt holes 35 of the mounting bracket 3. Drill the anchor bolt holes. The anchor bolt 5 is inserted and fixed in the anchor bolt hole, and a mounting bracket is fitted to the bolt portion 51 exposed from the wall surface of the anchor bolt 5,
The mounting bracket is fixed with a nut via the square washer. Next, the forward screw 61 of the two screw bolts 6 is screwed into the female screw 31 of the mounting bracket 3, and the female screw 11 provided on one side edge of the female screw 11 provided on the two side edges of the panel 1. Reverse screws 62 of both screw bolts 6 of the mounting bracket 3 are screwed into the screws 11. The female screw 11 on the side of the panel 1 to which the mounting bracket is not attached is brought into contact with the female screw 31 of the mounting bracket 3 fixed to the wall surface, and the panel 1 and the mounting bracket 3 are fixed with the two screw bolts 6. This operation is sequentially repeated, and panels are installed at desired portions of the inner wall surface of the tunnel. When the mounting level of the panel becomes uneven after the panel is installed, the two screw bolts 6 screwed into the two side edges of the panel 1 are rotated to adjust the distance between the panel 1 and the mounting bracket 3. The mounting level of the panel 1 is made uniform. After adjusting the level of the panel 1, the two screw bolts 6 are fixed with an adhesive or the like, and the female screw 11 of the panel 1 is filled with caulking or the like. As described above, the non-adjustable panel mounting structure according to the present invention has a panel provided with a plurality of female screws of reverse screws on each of two opposing side edges, and a plurality of forward screws on the base surface. Female screw is provided, one side surface of the base surface is bent at a substantially right angle to form a vertical surface, and the other side surface of the vertical surface is bent at a right angle to form a mounting surface, and a bolt hole is formed in the mounting surface. It consists of a drilled mounting bracket, a double screw bolt with a forward screw threaded from one end to the approximate center, and a reverse screw provided from the other end to the approximate center,
The mounting bracket attached to the wall surface and the panel are screwed with the two screw bolts, and the panel level can be easily adjusted by rotating the two screw bolts after the panel is installed. Since the two screw bolts are provided with a forward screw and a reverse screw, when the two screw bolts make one rotation, the panel is moved by two rotations, and the level of the panel can be adjusted with a slight rotation. In addition, when the panel is damaged, the panel can be easily removed only by removing the two screw bolts on the two sides of the panel.
Panels can be easily replaced.
