Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a wall member which is lightweight and excellent in heat insulation and soundproofing.

[Problems to be solved by conventional technology and invention]

Conventionally, various wall members have been proposed in the field of civil engineering.

Each of them is required to be lightweight, excellent in strength and durability, and excellent in various performances as a wall material such as heat insulation and soundproofing, and various materials and structures have been proposed.

The present invention proposes a wall member that is superior to these conventional materials.

[Means for solving the problem]

 The gist of the present invention will be described with reference to the accompanying drawings.

A hollow spherical shell 1 having a different size and having an air suction portion 1 'formed by polymerizing and joining two half halves 2, 2' together is provided.
The air suction portion 1 'removes the inside air to make the air thin or almost vacuum, and the wall-forming material hollow shell a or one end of the pipe 7 is closed, and the inside is opened from the opposite open end 7'. The wall member is characterized by being filled with a hollow shell b for a wall component, in which the air is diluted to a state close to a vacuum by removing the air to a state close to a vacuum. .

[Action]

The two half halves 2 and 2 'are polymerized and joined to form a hollow spherical shell 1 having an air suction portion 1', and the air inside is removed from the air suction portion 1 'to make the air thin or vacuum. A large number of hollow shells a for a wall component in a state close to the above are manufactured.

Since the two halves are polymerized and joined, the hollow spherical shell 1 can be easily manufactured.

One end of the pipe 7 is closed, and the air inside the pipe 7 is made thin or nearly vacuum from the opposite open end 7 'and eliminated to produce a large number of hollow shells b for wall components.

The hollow shell a for a wall component and the hollow shell b for a wall component according to the present invention are used, for example, as panel plates 4.4 for forming concrete walls.
Fill in the space, pour concrete 5 into the void,
Allow to cure to form walls.

A wall member mainly composed of a hollow shell a or a hollow shell b for a wall component whose internal air is diluted or evacuated, and a hollow shell a for a wall component or a hollow shell for a wall component. Since the hollow interior of the shell b is in a state of vacuum or near vacuum,
It has a light upper shell shape due to its hollowness, so it has strength, and exhibits excellent heat insulation and soundproofing due to vacuum.

In addition, by using both of them or mixing them with other wall forming materials, they can be buried in a dense state in the wall cross section, and good wall strength can be secured.

〔Example〕

In the drawing, a joining flange 3, 3 'is protruded from a synthetic resin split half 2, 2', an air suction section 1 'is protruded at one place, and a suction pipe 8 of a vacuum pump is connected. (The drawing shows a fitting type, but a type that inserts and connects to the suction hole 6 may be adopted.) At the same time as suctioning the air inside the hollow spherical shell a through the suction hole 6 The air suction part 1 'and the flanges 3, 3' are melt-bonded by high frequency heating.

In this case, it is desirable to use a non-twist synthetic resin that is well heat-welded.

The air suction part 1 'may be provided in any structure without providing it in a protruding state as long as air suction is possible.

The half halves 2.2 'may be made slightly thicker without providing the flanges 3.3'.

Instead of using high-frequency heating, other heat bonding or bonding using an adhesive may be used.

 The hollow shell a may be made of metal.

In addition, a pipe 7 made of metal or synthetic resin is used as a material, and one end of the pipe 7 is closed, and the air inside the pipe 7 is made thin or close to a vacuum from the opposite open end 7 'to eliminate and close the pipe. The same applies to the case where the hollow shell b is formed (reference numeral 9 denotes a welded portion, and 8 'denotes a closing plate).

The hollow shells a and b may have a diameter substantially equal to the thickness of the wall, or a slightly smaller diameter, and the original wall material, for example, five layers of concrete may be disposed on the outer surface, and the hollow shells may be formed. It is desirable to conceal the bodies a and b.

FIG. 3 shows a similar small hollow shell a ', b' or a small mass 10 as a mere filler to fill the gap formed between the hollow shells a, b. The case where a concrete wall body is formed by drawing is shown.

〔The invention's effect〕

As described above, the present invention can easily provide hollow shells a and b with a hollow interior that is close to or close to a vacuum, and since the hollow spherical shells a and b are used as wall forming materials, an upper spherical or cylindrical shape that is lighter than the hollow portion The hollow shells a and b have extremely good load strength due to the shape, and the hollow shells a and b are arranged in a packed state to form a wall. In addition, since the hollow portions of the hollow shells a and b are evacuated, they constitute a wall exhibiting extremely excellent heat insulation and soundproof characteristics.
