Abstract

PURPOSE:To surely mount without separating a radio wave absorbing material by mounting a mold frame having a corrugated section on the rear side of a finishing material such as a stone and a large-sized earthenware plate, and compression-inserting the radio wave absorbing material into a groove part of the mold frame. CONSTITUTION:A mold frame 5 is mounted all over the rear side of a finishing material 2,.... The mold frame 5 is formed in the shape of a corrugated section of synthetic resin or the like. A radio wave absorbing material 7 such as a ferrite tile is compression-inserted into the groove parts 5a of a mold frame 5 extending over the whole length, accordingly, the whole wall surface of a concrete body 1 is completely covered with the radio wave absorbing material 7. Further, polymer cement mortar 8 is applied to the surface of the mold frame 5 so that the radio wave absorbing material 7 may not separated from the groove parts 5a.... Further, a sheet 9 such as butyl rubber sheet or the like having adhesiveness is adhered to the surface of the polymer cement mortar 8, and thereby the whole mold frame 5 is closely adhered to the rear of the finishing material 2 with no gap.

Description

[Detailed description of the invention] [Industrial application field] This invention relates to a radio wave absorbing wall.

[Conventional technology]

In areas where high-rise buildings are lined up, radio wave absorbing materials are often installed on the walls of buildings to avoid radio wave interference caused by the buildings.

Conventionally, ferrite tiles have been mainly used as this type of radio wave absorbing material.

Ferrite tiles are attached to the walls of buildings using adhesives or the like, and their surfaces are generally covered with a finishing material such as ceramic tiles or stone.

[Problem to be solved by the invention]

However, with such a construction method, it may not be possible to reliably bond the concrete frame and the ferrite tile and the finishing material and the ferrite tile depending on the construction conditions.

For this reason, even if the tiles were bonded at the beginning of construction, there was a risk that the adhesive ability would decrease over time and the finishing material and ferrite tiles would peel off.

For this reason, a method of binding ferrite tiles, etc. one by one to the reinforcing bars of a concrete structure using binding wires has been carried out, but the construction is generally cumbersome.

This invention was proposed in order to solve the above-mentioned conventional problems, and it is possible to reliably attach the radio wave absorbing material, and completely prevent peeling and positional shift after attachment. Moreover, it is an object of the present invention to provide a radio wave absorbing wall body that can be easily constructed.

[Means to solve problems]

This invention relates to a radio wave absorbing wall, in which a finishing material is attached to the wall surface of a concrete frame, and a formwork with a substantially wave-shaped cross section is attached to the back side of the finishing material so that the grooves of the formwork are continuous in the vertical direction. In addition, the above object is achieved by having a configuration in which a radio wave absorbing material is attached to the groove portion over its entire length.

〔Example〕

The present invention will be described below based on an illustrated embodiment. A finishing material 2 such as a large ceramic board or stone is attached to the wall surface of a concrete frame 1 over the entire wall surface (first
(see figure).

Finishing material 2. . . . are formed into rectangular plate shapes of a predetermined size, and are firmly fixed to anchor members 3 protruding from the wall surface of the concrete II body 1 by means of mounting hardware 4.

Each finishing material 2. A formwork 5 is attached to the back side of the finishing material 2 (see Fig. 2).

The formwork 5 is formed of a synthetic resin material or the like and has a corrugated cross section.

In addition, the formwork 5 is installed on the back side of the finishing material 2 with grooves 5a, .
(See Figure 2).

A radio wave absorbing material 7 such as a ferrite tile is compressed and inserted into the groove 5a of the formwork 5 over the entire length of the groove 5a (
(See Figure 3).

Therefore, the entire wall surface of the concrete A body 1 is completely covered with the radio wave absorbing material 7.

Furthermore, a polymer cement mortar 8 is applied to the entire surface of the formwork 5 to prevent the radio wave absorbing material 7 from peeling off from the groove portion 5a (see FIG. 5).

Further, a sheet 9 such as a butyl rubber sheet having adhesive properties is adhered to the surface of the polymer cement mortar 8, so that the entire formwork 5 is tightly attached to the back surface of the finishing material 2 without any gaps.

Therefore, even if the finishing material 2 is damaged, its fragments will not fall.

In addition, during construction, the radio wave absorbing material 3 is placed in the groove 5a of the formwork 5.
At the same time, a polymer cement mortar 8 is applied over the entire surface of the formwork 5, a sheet 9 is attached on top of the polymer cement mortar 8, and the formwork 5 is covered with a radio wave absorbing material 7. and glue it to the back side of finishing material 2,
In addition, by fixing with fixing fasteners 6, the formwork 5 and the finishing material 2 are made integral.

〔Effect of the invention〕

Since the present invention has the above configuration, it has the following effects.

■ A formwork with a roughly wave-shaped cross section is attached to the back side of a finishing material such as stone or large ceramic plate, and the radio wave absorbing material is compressed and inserted into the groove of the formwork, so if it is simply adhered with adhesive. Unlike conventional methods, there is no need to worry about the radio wave absorbing material peeling off, and the radio wave absorbing material can be installed securely.

■ Also, during construction, the radio wave absorbing material is compressed and inserted into the groove of the formwork, and this formwork is attached to the back side of the finishing material to integrate the finishing material and the formwork in advance, making it easier to install the finishing material. and the installation of radio wave absorbing material can be done at the same time. As a result, construction efficiency is significantly improved.
