2. Description of the Related Art In recent years, the price of land in urban areas has skyrocketed, and the height of buildings has risen, and the number of floors in basements has increased to increase the floor area. Since the outside of the reinforced concrete wall body (hereinafter referred to as the wall body) forming the basement is in direct contact with the soil, the surface of the wall body is equal to the temperature of the soil that maintains approximately the same temperature throughout the year. Therefore, when the temperature in the room is significantly higher than the wall surface, the air in the room comes in contact with the cold wall surface to be below the dew point and to be condensed on the wall surface.

Conventionally, in order to avoid this, as shown in FIG. 22, a moisture permeable material such as a concrete block 4 is piled up on the side of the room 3 at a distance from the surface of the wall 2 which is in contact with the outer soil 1. The inner wall 5 is formed. In this state, the surface 5a of the inner wall 5 on the room 3 side does not condense, and the moisture in the room 3 permeates the inner wall 5 and condenses on the wall 2 surface. Usually, this condensed water is guided to a water channel 6 provided at the bottom between the inner surface of the wall and the inner wall 5 and discharged. The water channel 6 is also used when the wall body 2 leaks water from the soil 1 side.

However, in order to stack the concrete blocks 4 to form the inner wall 5, the joints must be filled with mortar. Further, since concrete blocks are heavy, if they are piled up to a certain height or more, a girder 7 of reinforced concrete must be provided on the way to reinforce the connection with the wall body 2 to some extent. It is a labor-intensive process that requires a lot of work and is humid and adversely affected. Also, the concrete block 4 has a thickness of 10 cm or more, and the joint mortar has fallen on the back part of the concrete block 4 so that it does not flow badly into the waterway.
The inner wall 5 has to be formed at a predetermined distance 8 from the water channel 6, which has the disadvantage of reducing the usable floor area.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and the space between the wall and the body can be freely adjusted.
An object of the present invention is to provide a base material for a double wall in which the inner wall is easily formed by attaching the plate material without dropping the joint material on the back surface of the inner wall.

[0006]

In the double-walled base material of the present invention, a columnar body having at least a flat surface in the length direction and having the same cross section, and locked to the columnar body. The mounting member having at least a surface parallel to the flat surface in the lengthwise direction of the columnar body and the flat surface of the mounting member were inserted, and this surface was clamped and fixed by a nut. The problem has been solved by providing a rod-shaped body provided with a male screw and a means for locking the tip of the rod-shaped body to the wall body.

[0007]

1 and 2 show an embodiment of a base material for a double wall according to the present invention, in which reference numeral 11 is a columnar body having an H-shaped cross section. The columnar body 11 has a flat surface 12 in the length direction, and is a mounting bracket 13 formed by bending a plate body into a predetermined shape.
Is locked to a predetermined position of the columnar body 11 by a bolt 14 and a nut 15. A surface 16 parallel to the flat surface 12 is formed on each of the mounting brackets 13.

The surface 16 is provided with a bolt hole 16a into which a rod-shaped body 17 having a male screw 17a is inserted.
It is designed to be tightened by holding nuts 19 and 19 via the washer 18. Further, on the vertical surface of the wall body 20, the female screw 2 in which the male screw 17a of the rod-shaped body 17 is screwed at a position facing the bolt hole 16 in the vertical direction.
A sleeve 21 in which 1a is cut is embedded and fixed.

In order to form the inner wall by using the above-mentioned double wall base material, first, the rod-like body is screwed and fixed to the sleeve 21, and the holding nut 19 is screwed into the rod-shaped body. Next, the rod-shaped body 17 is inserted into the bolt hole 16a formed in the surface 16 of the mounting bracket mounted on the columnar body 11, and the other clamping nut 19 is inserted.
The columnar body 11 is fixed by screwing together and tightening the surface 16 of the mounting member 13 by adjusting the position of the surface 12 of the columnar body 11 with both holding nuts 19 and 19. In this way, the plurality of columnar bodies 11 are attached at intervals in the lateral direction to form a double wall base.

For example, a rectangular plate member 2 having the actual joining portion on the surface 12 of the columnar body of the large base thus formed.
In order to fasten 2, the plate material 2 is fixed by the known method while fixing the known plate material fitting 23 with the pop rivet 24.
2 is fastened and the inner wall 25 is formed.

In the above description, the sleeve 20 is attached to the wall 20.
1 is fixed, but the rod-shaped body 20 is divided into two as shown in FIG. 3, and the female screw 21a of the sleeve 21 and the male screw of the rod-shaped body 30 screwed to this are made reverse screws, which are connected by the turnbuckle 31. It is also possible to further facilitate the adjustment of the unsteadiness of the surface 12 of the columnar body 11.

Further, as shown in FIG. 4, instead of the sleeve 21, a bolt 32 is fixed to the wall body 20, and the turnbuckle 31 is fixed.
Can also be connected. At this time, an ordinary bolt 33 having a head portion may be used instead of the rod-shaped body 17 as shown in FIG. 5, but when it is inserted into the bolt hole 16a of the mounting bracket, it may be difficult to insert the bolt-shaped body 17 and the rod-shaped body may be difficult. It is more convenient to use 17 and two clamping nuts 19, 19.

The material of the columnar body 11 is not particularly limited, but an extruded product made of a ceramic material such as a metal product, a plastic product or cement mortar is used, and if a stainless steel plate is used as a fitting, corrosion resistance and fire resistance can be obtained. Since the ceramic material is also excellent in heat insulation property, even if it is used for the double wall of the basement, the base material does not form a cold bridge and dew on the inner wall 25.

In the above-mentioned mounting fixture, the columnar body 11 has a flat surface 12 in the longitudinal direction, and the mounting fixture 13 locked to this by a bolt 14 and a nut 15 is a surface 1 parallel to the flat surface 12.
6, the shape is not limited. For example, as shown in FIGS. 6 to 8, even if the shape of the metal fitting 13 or the position of the plane 16 is different, or the cross-sectional shape of the columnar body 11 is H-shaped. It doesn't have to be.

Further, as shown in FIG. 9, a bolt hole 16a for inserting the rod-shaped body 17 may be formed by inserting the surface 16 of the mounting member 13 and a part of the columnar body.

Further, the columnar body 11 and the mounting member 13 may be engaged with each other firmly. For example, as shown in FIGS. 10 to 15, the groove 41 of the columnar body 11 having an H-shaped cross section is formed. The mounting bracket 13 may be engaged by the repulsive force.

Further, as shown in FIGS. 16 to 19,
The present invention also includes an H-shaped one in which the projection 42 is sandwiched and the hook claw 43 at the tip is hooked in the narrow groove 44 of the columnar body 11.

In order to form the columnar body used in the present invention, the columnar bodies may be extruded one by one, but as shown in FIG. 20, a hollow extrusion molded plate 51 having parallel through holes 51a.
Can be cut as shown by the chain double-dashed line, or the known corner material 52 shown in FIG. 21 can be diverted.

As described above, the double-walled base material of the present invention is formed with the columnar body having the same transverse cross section and having the plane in the lengthwise direction, and the plane parallel to the plane in the lengthwise direction of the columnar body. Since it is locked with a mounting bracket that is attached to the wall body by means that can freely adjust the distance to the wall body, it is lightweight and has good workability, and the planar position of the columnar body in the longitudinal direction can be adjusted. It is easy to adjust the unevenness of the inner wall and the construction cost is low.

Further, if the columnar body is made of a ceramic material, the base material is a non-combustible material, at the same time no rust occurs and no cold bridge occurs. In addition, since the hollow plate material can be manufactured by cutting and the waste material and the corner material can be used, the material cost can be reduced and the waste material can be effectively used.
