Abstract

PURPOSE:To prevent the breaking accident of a hard wall member at the time of fitting work by integrally fixing a fitting member to be fitted to a wall backing to the hard wall member, and by fitting the hard wall member to the wall backing via the fitting member. CONSTITUTION:A hard wall member A is made in a honeycomb structure, and engaging grooves 4, 5 are provided and formed in both end side walls in the width direction of the dressed surface. The fitting member B to be fitted to a wall backing alpha is made up of lockedly engaging pieces 8, 9, lockedly engaging grooves 10, 11 (not shown), upper and lower end fitting pieces 12, 13 (not shown), and a fitting piece 14 so as to constitute a tongue and groove joint structure. The lockedly engaging pieces 8, 9 of the fitting member are inserted into the engaging grooves 4, 5 of the hard wall member A, and the hard wall member A and the fitting member B are integrated by means of the upper and lower end fitting pieces 12, 13, a fitting groove 15, or the like. Then, the fitting piece 14 of the fitting member B is fixed to the wall backing alpha, and the hard wall member A is fixed to the backing alpha. Thus, the hammering at the time the hard wall member is fitted can be dispensed with, so that the breakage and separation thereof can be prevented.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a hard wall material having a hollow hole inside by using a fixture and an adhesive for a new construction wall base, or ALC, RC construction, SRC construction, mortar construction, hollow cement board (PC). The present invention relates to an attachment structure that can be easily attached to an existing wall base such as a plate).

[0002]

2. Description of the Related Art Generally, tiles, bricks,
As a structure to attach a hard wall material such as ceramic or natural stone, mortar is fixed as an adhesive, or the surface of the hard wall material is drilled and drilled, and a fixing tool such as a screw is used to brain strike a new wall base, or It was usually attached to an existing wall base.

[0003]

However, the structure in which the hard wall material is mounted with the mortar has a problem in durability and earthquake resistance, and there are drawbacks such as cracking and the hard wall material peeling from the wall foundation. Yes, it was not possible to construct heavy objects. In addition, it takes time for the mortar to harden, and during that time, there is a risk that the hard wall material may come off from the wall foundation. Furthermore, when the hard wall material is drilled by drilling and the fixing tool is brain hammered, the hard wall material may be damaged by a hammer etc. when the hard wall material is attached, or the fixing tool has a decorative surface. In addition to the drawbacks such as lacking in designability, there was a drawback in vibration resistance.

[0004]

In order to eliminate such a drawback, the present invention inserts and fixes a fixture on both ends of a hard wall member through engaging grooves of the hard wall member and attaches the upper part of the fixture. The surface is fixed to the wall foundation with a fixture, and the hard wall material is attached to the wall foundation by the male-female connection structure of the fixture, the fixture and the fixture do not appear on the surface at all, and the hard wall material itself Proposes a mounting structure for a hard wall material that does not require separate processing, is excellent in mounting strength, designability, workability, durability, and earthquake resistance, and does not separate the hard wall material from the wall base.
