Description

[Detailed Description of the Invention] "Field of Application of the Invention" This invention relates to a structure for attaching decorative waist wall panels to tunnel side walls.

"Prior art" Generally, the waist walls of the side walls of road tunnels, etc.
Since it is easily visible from the train window and an evacuation passage is provided in this area, tiles, decorative boards, etc. are often installed to give it a nice exterior appearance.

By the way, installing decorative tiles on-site results in poor work efficiency and increases construction costs and construction time, so in recent years a construction method has been developed that involves installing waist walls made of PC boards with tiles attached to the surface in advance. It's coming.

This invention proposes a mounting structure for a waist wall board that can be easily and reliably installed and that can be easily maintained and replaced.

The following describes an embodiment of this invention shown in the drawings. The waist wall board 1 is made of a rectangular PC board with tiles 2 attached to its surface, and a downward hook-shaped engaging part 3 is provided on the back surface of the upper end. Further, joint convex portions 4 are formed on the back side of both end portions.

The waist wall boards 1 formed in this manner are supported at their lower ends on a fixing member 6 that has been installed and fixed in advance on the floor 5, and are connected from side to side along the tunnel side wall 7 with their sides in contact with each other. The hooking portion 3 of each waist wall board 1 is hooked with an upward hook-shaped hooking portion 9 provided at the tip of a support plate 8 whose base end is fixed to the side wall portion 7 in advance and protrudes forward at a predetermined interval. and the side wall portion 7
is supported by

Moreover, the waist wall boards 1, 1 which are arranged in a row on the left and right sides are integrally fastened at their side ends by fastening members.

In the embodiment shown in FIG. 2 as this fastening member, an arc-shaped concave groove 1 is formed at the corner of the side surface of the joint convex portion 4 of the waist wall board 1 and continues from the side surface to the back surface thereof.
0 is formed and the waist wall boards 1 are installed side by side on the left and right,
The grooves 10, 10 are configured to join together to form a series of arcuate grooves.

An arc-shaped fastening band 11 is integrally fitted into the concave grooves 10, 10 of the left and right adjacent wall boards 1, 1, and a fastening piece 12 protruding from the back side of the waist wall board 1. 12 with bolts 13, the left and right waist wall panels 1, 1 are integrally connected to each other at their corner portions.

In addition, as another fastening member, in the embodiment shown in FIG. 1 are configured to be integrally fastened together.

The fixing member 6 is, for example, a groove-shaped member that tightly fits the lower end of the waist wall board 1 as shown in FIGS. 1 and 4.
Alternatively, it may be made of an L-shaped material with a convex portion 16 on the flat part to fit into the recess 17 provided at the lower end of the waist wall board 1, and can be easily positioned and fixed by dropping the waist wall board 1 from above. It is configured so that it can be done.

During construction, support plates 8 are protruded from the side wall 7 at intervals corresponding to the width of the waist wall board 1, and fixing members 6 made of PC material are placed in series along the side wall 7 on the concrete floor 5. Install and fix.

Next, the waist wall board 1 is lifted up and the engaging part 9 of the support plate 8 is engaged with the engaging part 3 at the upper end of its back surface, and at the same time, the recessed part 17 at the lower end is engaged with the convex part 16 of the fixing member 6 to position and fix the upper and lower parts. while connecting the left and right,
Further, adjacent waist wall boards 1 and 1 are formed with grooves 10 and 10.
They are integrally fastened by a fastening band 11 fitted therein or a bolt 15 inserted through a bolt insertion hole 14.

By continuing this construction in the horizontal direction, a series of waist walls whose surfaces are decoratively finished with tiles or the like is constructed.

``Effects of the invention'' As described above, according to this invention, waist wall boards with downward hook-shaped engaging parts on the back side are connected from side to side, and supporting members protruding from the tunnel side walls are attached to the engaging parts. The upward hook-shaped engaging portion provided at the tip is engaged, and the side ends of the left and right waist wall boards are fastened and integrated with each other by a fastening member. By engaging and positioning the upward hook-shaped engaging parts, and by fastening and integrating the side ends of the left and right waist wall boards with the fastening member, the mounting member attaches the adjacent waist wall boards to each other on their back sides. It is possible to easily fix the panels in one piece without exposing them to the surface, making it possible to construct a series of good-looking waist walls in a short period of time and at low cost. If so, it can be easily repaired by replacing it with new wainscoting.
