DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waterproof device for a basement, and more particularly to a waterproof device using a wall panel.

[0002]

2. Description of the Related Art In a basement having an outer peripheral wall composed of a wall panel, a surface material to be attached to a frame of the wall panel is made of a waterproof metal plate or the like, thereby constructing a basement having a panel structure with excellent waterproofness. Is thought to be.

[0003]

As described above, by constructing the basement with panels, there are advantages that the construction period can be shortened and the cost can be reduced as compared with a concrete structure cast in place. However, since there are many half-face joints, waterproofing work is required to prevent the penetration of groundwater. As an example, in a case where a wall panel is composed of a frame-shaped frame and a face material, waterproofing of a joint portion between the frame and the face material may be mentioned. In this case, the frame and the face material are usually joined by welding. However, in the case of full-circumferential welding, if there is a poor welding portion, water may permeate into the panel from there. Therefore, high-precision welding is required between the frame and the face material, and this causes a rise in the manufacturing cost of the panel itself.

An object of the present invention is to provide a basement wall panel comprising a frame-shaped frame and a surface material attached to the frame, and to waterproof the joint between the frame and the surface material at low cost. It is to make.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention comprises an outer peripheral wall of a basement comprising a wall panel having a frame-like frame and a surface member attached to an outer surface of the frame. A groove is formed along the joint between the end portion of the face material and the frame, and a sealing material is filled in the groove to constitute the joint in a watertight manner. I do.

According to the invention of claim 2 of the present application, a step is formed on the outer surface of the frame, the inner edge of the frame being recessed inward in the width direction of the frame. A step is provided, wherein a step is formed in which an edge portion is depressed in the same direction as the step, and the steps are overlapped and joined to each other to form the concave groove.

[0007]

As described above, since the joint between the frame and the face material is sealed, the permeation of groundwater can be prevented even if there is a defect in the welded joint. Further, it is not always necessary to weld the face material and the frame to the entire circumference to perform watertightness.

1 shows a section of a basement using a wall panel according to the present invention. In the figure, (1) is a slab concrete cast in place on a discarded concrete (8) at the bottom of the underground excavated ground, and (2) is a slab concrete (1)
1 shows a steel base having a substantially U-shaped cross section, which is installed on the upper surface of a steel plate. The base (2) is installed along the outer peripheral wall of the basement with the U-shaped opening facing inward, and the upper surface of the base (2) is made of steel constituting the outer peripheral wall. The wall panel (3) is fixed. At this time, a swellable packing material (5) is interposed between the back surface of the wall panel (3) and the upper surface of the upper flange (4) of the base (2). An anchoring bar (6) bent in an L-shape is welded to the back surface of the lower flange (10) of the base (2) and buried in the foundation concrete (1).

On the upper surface of the wall panel (3), an inner side of an outer peripheral beam (7) made of H-section steel is installed, and is fixed to the wall panel (3) with bolts (9). Further, a steel deck (10) used for roof material and the like is installed inside the outer peripheral beam (7), and a roof concrete (11) made of unreinforced concrete is cast on the upper surface thereof. (12) shows the wall frame of the building on the ground floor, which is installed on the outer beam (7).

Before the foundation concrete (1) is cast, the base (2) is mounted on a base concrete (8).
(13) It is installed temporarily on the
(13) consists of an L-shaped lower fixing part (14) and an L-shaped upper receiving part (15) which is turned upside down.
6) (17) is superposed inside and outside of each other, and connected by horizontal bolts (17) inserted into both.

As shown in FIG. 2, the wall panel (3) includes upper and lower horizontal frames (20) and (20) each having a roughly groove-shaped cross section, and a pair of left and right vertical frames (21) and (21) also having a roughly groove-shaped cross section. ) To form a square frame-shaped frame (22), and a surface material (23) made of a thin waterproof material such as stainless steel is adhered to the outer surface thereof. Further, a folded plate member (24) is fitted in the frame (22) in a fitting manner so as to support the earth pressure from the outside and the load from above.

In the above description, the inner edge of the flange (24) is recessed inward in the width direction of the frame (22) on the outer flange (24) of the frame (22) to which the face material (23) is joined. Such a step (25) is formed. On the other hand, the outer peripheral end of the face material (23) is similarly formed with a step (26) that is depressed inward in the width direction of the frame (22). Then, a piece at the tip of the step (26) of the face material (23) is placed outside the step (25) of the frame (22) so as to be superimposed, whereby the wall panel (3)
A groove (27) as shown in FIG. 3 is formed on the outer surface of the sealing member. The sealing material (28) is filled in the groove (27) thus formed, and joined. The part is waterproofed. Further, the frame (22) and the face material (23) are joined by welding or the like. However, since the frame (22) and the face material (23) are waterproofed by the sealing material (28) as described above, it is not always necessary to perform welding on the entire circumference.

Further, as shown in FIG. 1, the wall panel (3)
The lower horizontal frame (20) is secured by bolts (29).
It is fixed to the upper flange of (2). And
On the outside of the wall panel (3), a protective layer panel (30) thicker than the face material (23) is installed in close contact.
(28) is filled in the groove (27), so this sealing material
By (28), the protective layer panel (30) does not rise.

A floor concrete (32) is cast on the base slab concrete (1) via a waterproof sheet (31).

[0015]

As described above, according to the present invention, since the joint between the wall panel frame and the face material is provided with a concave groove and filled with the sealing material, the permeation of groundwater from this joint is achieved. There is an effect that can be prevented. In addition, even when these frames and face materials are joined by welding, high-precision welding for obtaining complete waterproofness is not required, and it is not always necessary to perform full-circle welding. It can be manufactured in. In addition, by providing a seal in advance, it is not necessary to perform waterproofing at this site on site, and the working period can be shortened accordingly.

Furthermore, since the sealing material is filled with the concave groove, the sealing material does not protrude from the surface of the panel, and there is no inconvenience such as being damaged by collision with other members during transportation or construction. As described above, even when a panel or the like for a protective layer is provided on the outside, the effect that the panel does not rise can be obtained.
