2. Description of the Related Art Double walls are effective in preventing the temperature inside a room from escaping to the outside in cold regions and the like, but are widely used especially for improving the environment of the basement. The basement is made of reinforced concrete walls (hereinafter referred to as walls), but the outside of the walls is in direct contact with the soil, so the wall surface is equal to the temperature of the soil, which 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 dew on the wall surface.

Conventionally, in order to avoid this, as shown in FIG. 10, a moisture permeable material such as a concrete block 4 is piled up on the inside of the room 3 with a space from the inner surface of the wall 2 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 indoor 3 side does not condense, and the moisture in the room 3 permeates the inner wall 5 and condenses on the surface of the wall body 2. Usually, this condensed water is guided to a water channel 6 provided at the bottom between the wall surface 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. When the piles are stacked to a certain height or more, a reinforced concrete girder 7 is provided in the middle of the wall 2
Since it is necessary to reinforce the connection, it is a labor-intensive work that requires manpower in a bad and humid environment. In addition, since the concrete block 4 has a thickness of 10 cm or more, the joint mortar drops on the back and enters the waterway, which causes poor flow.
The inner wall 5 had to be formed at a predetermined distance 8 from the water channel 6, which had the disadvantage of reducing the usable floor area of the basement.

As a solution to this, the present applicant has
As shown in FIG. 11, a plate material 1 that forms an inner wall on the surface of the wall body 2
Underground pillars 12 are projected according to the size of 1, and the back support 1
3 is arranged and fixed on the surface of the wall body 2 and the plate member 11 is arranged,
The inner wall 5 was formed by fixing the both side edges to the underground pillar 12 with the fasteners 14. The back support member 13
Is usually adhered to the opposing surfaces of the wall body 2 and the plate member 11 with an adhesive 15 to connect them.

However, when the temperature of the surface of the wall 2 is lower than the temperature of the room 3, it is said that the back support member 13 has good heat conduction.
Since this becomes a cold bridge and dew condensation occurs on the surface of the plate material 11,
By using a synthetic resin foam as the back support material 13, it is possible to prevent the bridge from becoming a cold bridge and to have a function as a back support material.

Although dew condensation on the surface of the plate material 11 can be prevented by this method, the distance between the underground columns 12, 12 is narrow and the number of them is large, which not only increases the construction cost, but also increases the wall 2 and the room 3.
When the temperature difference of 1 becomes larger, the above-mentioned pillar 12 may become a cold bridge and dew on the plate 11.

Therefore, as shown in FIGS. 12 to 15, the applicant of the present invention further supports the back surface of the plate member 11 by the back surface support member 13 made of synthetic resin foam, and the vertical connecting portion 16 of the plate member 11 in the basement. We proposed a double wall in which the space between the underground pillars 12 is widened by supporting the C-channel ground pillars 18 which are perpendicular to the floor 17 (Japanese Utility Model Application No. 62-1235).
27).

[0009]

However, the supporting member for supporting the vertical joint portion 16 is the rear surface 1 of the base pillar 18.
8c is the position of the vertical joint portion 16, and the washer 20 is sandwiched between the support rod 19 having the male screw 19a around the head portion embedded in and fixed to the wall body 2, and the nut 21 is screwed with the washer 20 interposed therebetween. When the washer 20 is fitted, the opening portion 18 of the C-channel foundation pillar 18 is
After sandwiching both side lip portions 18b of a, tightening the nut 21, and fixing the C channel column 18, the rear portion 18
The end of the plate material 11 is fastened to c by screws 22 or the like.

However, when the two washers 20, 20 are positioned opposite to each other and tightened with the nut 21, the washer 2
Not only is it difficult to prevent this, but also after mounting it, the two nuts must be moved in order to adjust the position of the washer 20 with respect to the support rod 19. Along with this, the facing positions of the two washers are apt to change, and there is a drawback that it requires skilled man and time to prevent this.

The present invention has been made in view of the above circumstances, and a support rod that is fixed to the opening of the base pillar and that adjusts the distance between the surface of the wall body and the base pillar can be easily attached. An object of the present invention is to provide an integrally formed fixture for a double-walled base pillar.

[0012]

SUMMARY OF THE INVENTION According to the present invention, there is provided a fixture for a double-walled base pillar for fixing a base pillar having an opening of a predetermined width on one surface thereof at a distance from an outer wall body. In addition, a sandwiching portion formed of parallel plate bodies that sandwich and fix the facing lip portions that form the opening of the base pillar is provided integrally on both sides, and between the sandwiching portions. As a means for solving the problem, a fixed metal object for a double-walled base column, which has a support mechanism in a direction perpendicular to the plate body, which is locked to the wall body, is used for this.

[0013]

Since the fixing hardware for the double-walled base pillar according to the present invention has the above-mentioned structure, the holding parts on both sides are positioned in the vertical direction and positioned in the opening, and when they are rotated by 90 °, both sides are fixed. The holding portion holds and fixes the lip portion of the opening of the base pillar.

The support rod is inserted through the fixed metal object fixed in this way, and the nut is attached to the support rod by a nut.
The fixed hardware does not move even if the position of the fixed hardware is adjusted.

[0015]

EXAMPLES The plate material used to form the inner wall used in the present invention is made of cement-based material and is lightweight and easy to manufacture. A hollow rectangular plate material 11 provided with a large number of parallel through holes 23 formed by extrusion molding is mainly used, but it is not limited to this as long as it has excellent air permeability.

FIGS. 2 to 5 show an embodiment of a fixed hardware (hereinafter referred to as a fixed hardware) 31 of a double-walled base pillar according to the present invention. The same parts as those in FIG. 15 are designated by the same reference numerals. To simplify the description. Reference numeral 32 in the drawing denotes a holding portion of a fixed metal member 31 which is located in the opening portion 18a of the C-channel-shaped base column 18 and in which plate bodies 32a and 32b for holding and fixing the lip portion 18b are formed integrally and in parallel. A bolt hole 33 is vertically formed in the center of the fixed hardware 31.

The fixed hardware 31 has a bolt hole 33 at the center.
It is easily formed by press-forming a rectangular metal plate in which the holes are formed.
Can also be molded at the same time.

In order to fix the C-channel base pillar 18 using the fixing hardware 31, as shown in FIG. 5, the holding portion 32 holds the lip portion 18b of the C-channel base pillar 18.
By fixing the fixed hardware 31 and the base pillar 1
8 is locked. At this time, the lip portions 18b may be clamped at the upper and lower ends of the opening 18a of the base plate 18 and may be displaced to a predetermined position, but the gap between the clamping portions 32 on both sides is formed narrower than the width of the opening 18a, The size is such that it can be rotated in the opening 18a, and the holding portion 3 of the fixed metal object is held in the opening 18a.
The fixed metal member 31 can be fixed to a predetermined position of the base column 18 by positioning the 2 in the vertical direction and rotating the same by 90 °. In this way, the distance for correcting the position of the fixed hardware 31 is small, and the lip portion 18b of the C-channel base column 18 is not damaged.

The fixed hardware 31 can be attached at a desired position in the lengthwise direction of the base pillar 18, and the holding portion 32 is provided.
Since the lip portion 18b is clamped by the spring force, the position of the lip portion 18b is not easily dropped, and fine adjustment of the position is easy by hitting with a hammer in the vertical direction.

In order to mount the base pillars 18 using the fixed hardware 31, first of all, the support rods 19 are fixed perpendicularly to the surface of the wall body 2 at intervals in the direction perpendicular to the surface of the wall body 2. The nut 21 is screwed.

Next, the fixing hardware 31 is fixed to the lip portion 18b of the opening 18a of the base column 18 at a position corresponding to the support rod 19 screwed with the nut 21 fixed perpendicularly to the surface of the wall 2. . The bolt holes 33 of the fixed hardware 31 attached to the base pillar 18 are inserted into the support rods 19, respectively. At that time, the position of the fixed hardware 31 is corrected if necessary. Next, the nut 21 is screwed through the spring washer 34, and the nut 2 screwed in front is also screwed.
The fixed hardware is clamped and fixed at 1. In this case, the nut 21,
21 are appropriately moved with respect to the support rod 19 and tightened, and the support rods 19 are provided at intervals in the vertical direction.
By this, the base pillar 18 is fixed and adjusted so that the distance to the wall body is constant, but even if the nut 21 is loosened, the fixing hardware 31 does not fall off, so the base pillar 18 is placed in the container. It is fixed in place. This foundation pillar 1
An inner wall is formed by fastening the end portion of the plate material 11 to 8 with screws 22.

In the above description, the fixed metal member is formed by pressing a rectangular metal plate, but may be any metal member having a holding portion on both sides and a bolt hole in the center, and is not limited to the above shape. Not something.

As a method of fixing the support rods 19 to the wall body 2, it is convenient to use the support rods as "post-installed anchors" or to fix the "post-installed sleeves" and screw them together. Alternatively, the support rod may be divided into two parts, one of which is reverse-threaded to the other and connected by a turnbuckle. All of these methods are known.

Further, although the C-channel base pillar is used as the base pillar, it suffices if the holding portion has a lip portion that holds the holding portion. For example, as shown in FIG. You may provide the opening window 35 in a part. Further, as the sandwiching portion 32 of the fixed hardware 31, the upper and lower positions of the center and both sides may be reversed as shown in FIG.

Further, in the fixed hardware 31, a bolt is inserted into the bolt hole 32, but at the position of the bolt hole 32, a sleeve 37 having a female screw as shown in FIG. 8 or 9, or a rod having a male screw is provided. The body 36 may be fixed and the support rods may be attached indirectly or directly to the wall.

[0026]

As described above, the fixed hardware of the double-walled base pillar according to the present invention is firmly attached to the base pillar by its spring force, and the vertical displacement can be adjusted. Since the rod can be easily attached and the length thereof can be easily adjusted, the base rod can be easily attached at a predetermined distance from the wall by the support rod. Therefore, skilled workers are not required for construction. In addition, it is easy to manufacture and can be manufactured at low cost, and it can be attached to a predetermined position of the foundation pillar in the factory and sent to the construction site, which simplifies the site work and makes it possible to perform inexpensive construction.
