Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure for a tunnel interior material. More specifically, the present invention relates to a tunnel interior material mounting structure that has weather resistance and durability as a tunnel interior material and can be prevented from falling off against vibration such as an earthquake.

[0002]

2. Description of the Related Art Generally, as a mounting structure for a tunnel interior material having a tile on a decorative surface, a hard calcium silicate plate is directly attached to a porcelain tile and fixed directly to the tunnel base through metal fittings fixed with screws or the like. It was something to do.

[0003]

However, this mounting structure has the following drawbacks. That is,
The fastening part of the fixture is often located behind the interior material,
Poor workability. Since the fixture is directly fixed to the tunnel interior material with screws or integrated, the weight of the tunnel interior material is concentrated at that location, which easily causes damage, and the surface condition of the tunnel base after construction. Changes easily cause breakage. If the tunnel interior material is damaged, it is difficult to replace it. Etc.

[0004]

In order to eliminate such drawbacks, the present invention is a long hollow body which is made of cement as a main raw material and is made of an inorganic material, and which is manufactured by an extrusion molding method.
A tunnel interior material consisting of a substrate having concave side portions on the upper and lower sides and tiles fixed to the surface of the substrate via an adhesive layer, and for fixedly connecting the tunnel interior material to the tunnel base at the side portions It consists of a two-member upper end fixing part, a three-member intermediate fixing part, and a one-member lower end fixing part, and is easy to install, and the interior material is less likely to be damaged and easily replaced even if damaged. Therefore, the present invention proposes a tunnel interior material attachment structure that is resistant to changes in the state of the tunnel foundation after construction and that allows easy installation of interior materials regardless of the state of the tunnel foundation or anchor bolts.

The interior material 2 can be molded into a cross-sectional shape as shown in FIGS. 9A to 9E to improve the design.

The substrate 3 is, for example, a long hollow body produced from cement, asbestos, admixture, water, etc. as a raw material, extruded, and then cured, autoclaved and the like. Since the side portion 4 is provided on the lower side, the rigidity is high and the strength is large, so that the supporting span can be made large, the number of fixing members is small, and the workability is good and the interior material is economical. In addition, it is a completely inorganic material, has excellent fire resistance, and does not ignite in the event of a fire in a tunnel.

Examples of the material include clay material obtained by crushing porcelain stone, feldspar, kaolinite, halloysite, metahalloysite, kibushi clay, frog eye clay, Shigaraki clay, etc. and kneading with water, or cement type, calcium carbonate. system,
Calcium silicate-based, wood cement-based, magnesium carbonate-based materials, sheathing boards, sheathing insulation boards, etc., or glass fibers, whiskers, aramid fibers, steel fibers, carbon fibers, various mineral fibers, various aggregates, etc. What was molded by extrusion molding, press molding, injection molding, papermaking method, etc., or various fibers woven in a cloth shape, three-dimensional shape, impregnated with cement, clay, etc. and molded into a panel shape It consists of steam curing or burning. By embedding the wire or passing it through the hollow portion, it is possible to enhance the prevention of scattering in the unlikely event of breakage.

Further, as the substrate 3, it is also possible to use a substrate containing clay as a main component, inorganic fibers and organic fibers added thereto, extruded as a hollow body, dried and baked at about 1000 ° C. or higher. .
