Abstract

PURPOSE: To make it possible to prevent dew condensation and toughen a lower panel and produce a seal effect and prevent the generation of strain in the radial direction as much as possible by connecting a base joint member of a lower panel frame to a joint member of a side wall panel frame with a fixture by way of an elastic body and a through hole and combining in the form of a box and spray a condensation preventive member on an interior wall surface. CONSTITUTION: A lower panel frame 5 is fitted in the bottom of a concrete interior wall where a ladder-like elastic body is installed to a horizontal joint of its base Joint member 5. When it is installed, continuous lengths of the ladder-like elastic body are properly cut based on the length of the base joint member and the position of a first through hole. Then, a ring-like elastic body is laid out and arranged to face each of the first through hole so that a side wall panel frame 6 may be placed on a lower panel frame 5. The horizontal joints of each of the joint members 5b and 6b of the lower panel frame 5 and the side wall panel frame 6 are aligned so that both panel frames may be connected to each other with a fixture 10. Then, a floor material is installed on the lower panel frame 5 by way of floor joists where a wall material is mounted on the side wall panel frame 6 and a ceiling is further mounted.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to an assembly structure of an underground structure for a general house.

[0002]

2. Description of the Related Art Heretofore, an example of this kind is Jikken Sho 63-6.
No. 261 publication. Therefore, the assembly structure of the underground structure described in this publication is, for example, a floor unit or a side wall unit, and a groove type rope (or a mountain rope) formed in a rectangular shape, and a groove type as the frame member. It consisted of a steel plate as a face material welded to the surface of the rope. When the floor unit (lower panel frame) and the side wall unit (side wall panel frame) are connected, the groove type rope and the mountain type rope, which are joints, are accurately aligned with each other and are fixedly connected by a fastener. Was.

However, in the assembling structure of the underground structure having the above-mentioned structure, since the groove type rope and the mountain type rope as the joints have substantially the same size, it is said that the positioning is easy and therefore the fixing work can be performed easily. However, when the floor unit and the side wall unit are combined, a device for preventing dew condensation is lacking, and although the floor unit has a design strength calculation, it has the above-mentioned configuration. Depending on the form of the underground structure, the desired toughness cannot be expected. Further, although an elastic body is generally interposed at the joint between the floor unit and the side wall unit, further sealing effect is expected. In addition, it has not been possible to do so, and further, sufficient measures have been not taken to eliminate the distortion of the side wall unit in the circumferential direction.

[0004]

In view of the above-mentioned drawbacks of the conventional techniques, the present invention can prevent dew condensation,
In addition, at least the lower panel frame is tough and has excellent durability, and can further exert the sealing effect of preventing water from entering. In addition, when the side wall panel frames are joined to the left and right and the front and rear, the circumferential direction It is to obtain an assembly structure of an underground structure that can prevent distortion to the utmost.

[0005]

and a plurality of base H-shaped ropes 5d which are provided integrally with a and are located in the base joined body 5b.

Further, in order to further exert the sealing effect of the elastic body, the elastic body is a ladder-shaped elastic body 11 arranged at the horizontal joint portion of the base joint body 5b of the lower panel frame 5.
And each first through hole 5 formed in the base assembly 5b.
It is characterized by comprising a plurality of annular elastic bodies 12 arranged in a required space 13 of the ladder-shaped elastic body 11 so as to face c. In addition, the width dimension of the horizontal joint portion 31 of the joint body 30 of the side wall panel frame 6A is set so that the distortion in the circumferential direction can be prevented as much as possible even when the side wall panel frames are joined to the left and right and the front and rear.

Is partly the same as the side wall panel frame 6A of the second embodiment (the same parts are denoted by the same reference numerals for convenience). That is, the horizontal joint portion 3 of the joint body 30a of the side wall panel frame 6B.
The width dimension of 1a is the same as that of the horizontal joint portion 32a of the base joint body 5b of the lower panel frame 5B, but the side wall portion is further formed on the upper surface of the horizontal joint portion 31a of the side wall panel frame 6B. A long reinforcing member 34 that abuts the side wall of the steel material 6d fixedly provided on the inner wall surface of the panel frame 6B.
Is fixedly provided. The reinforcing member 34 may be a steel material having an angle shape, a groove shape, or the like, but in this embodiment, a plate-shaped steel material is welded.

With this structure, as shown in FIG. 11, the side wall panel frame 6B is provided with the reinforcing member 34 even if a circumferential force is applied to the side wall panel frame 6B as indicated by an arrow. Distortion in the circumferential direction can be reliably prevented.

Although the reinforcing member 34 is added to the constituent requirements of the second embodiment, it may be added to the constituent requirements of the first embodiment as described above.

[0033]

As is apparent from the above description, the present invention has the following effects. (1) Condensation can be prevented. (2) To obtain a lower panel frame that can be used not only for a specific panel frame based on a design calculation but also for panel frames of various modes (side wall and upper panel frame) having different weights. You can (3) When the elastic body has a double structure, it is possible to further exert the sealing effect of preventing water from entering. (4) In the case of the second embodiment and the third embodiment, even if the side wall panel frames are joined to the left and right and front and rear in a box shape, it is possible to reliably prevent distortion in the circumferential direction.
