DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connecting structure of an inner wall component, for example, a water leakage prevention wall in a building, a basement, an underground parking lot, and the like on the ground.

[0002]

2. Description of the Related Art This kind of internal structure wall is disclosed in
-68066, JP-A-8-105067 and the like. These are related to the inner wall components having a water leakage prevention wall, provided with a water leakage prevention wall on the inner wall surface of the concrete wall, and through a water passage provided in the water leakage prevention wall,
It is designed to drain water. The formation of the water leakage prevention wall
According to the usual concrete wall forming method, a concrete placing area is formed by two rows of concrete forms arranged at intervals. The concrete formwork to be the inner wall (inside of the room) is replaced with a water leakage prevention member having a water passage, and is used as a concrete wall casting formwork. When the concrete hardens and the formwork is removed, the water leakage prevention member is removed. Not used as the inner wall. At present, when making the mold wall with leakage prevention member having a water passage, sandwiched butyl rubber vertically joints to prevent seepage of waste water from the back side, the horizontal joint between the coupling member (hereinafter referred to Joyner) Butyl rubber is used in combination to prevent seepage of wastewater. FIG. 8 is a longitudinal sectional view showing a horizontal joiner in a connecting portion of a conventional water leakage preventing member, and FIG. 9 is a transverse sectional view of a vertical joint portion of the connecting portion.
Shown in In the drawing, reference numeral 1 denotes an inner wall component, for example, a water leakage prevention member. The leakage prevention member 1, the surface plate member 2, the water passage member 3, made of non-woven fabric 4. 8 is a horizontal joiner and 9 is butyl rubber. The drawing shows a state in which an upper water leakage prevention member 1 'and a lower water leakage prevention member 1 "are positioned and joined by a horizontal joiner 8. According to a conventional structure, as shown in FIG. Surface plate member 2 of member 1
The end 8 'of the horizontal joiner 8 is exposed on the inner wall surface 2'.
In the figure, reference numeral 13 denotes a mold provided on the outside.
Concrete is poured in between 3 to form the wall of the building.

[0003]

As described above, according to the prior art, a coupling member (hereinafter referred to as a "joiner") is exposed on the surface of the water leakage prevention wall at the connecting portion of the water leakage prevention member. I have. For this reason, the appearance is poor and it becomes an obstacle when trying to paint or tile the inner wall surface. Also requires butyl rubber as rubber packing
Therefore , it takes time and effort to fit the material, and the material cost increases.

[0004]

To solve the problems described above SUMMARY OF THE INVENTION In the present invention, coupling members for connecting the inner wall configuration member so as not to appear on the surface of the inner wall configuration member, the surface plate member of the inner wall configuration member together the pay coupling member on the back Oguchi
In addition, watertightness is maintained without using rubber packing to prevent water leakage.
The structure shall be such that it can be prevented .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIGS. 1 and 2 , the present invention comprises a front plate member 2 such as a fiber reinforced cement plate, a metal plate and other non-combustible plate members, and a back member having a water passage such as a hollow water passage. The leakage prevention member 1 is formed by bonding to the plastic molded body 3 with an adhesive. The end of the surface plate member 2
A fore edge 10 is provided by the back surface of the contact portion and the plastic molded body 3 . At the time of assembling the water leakage prevention member 1, both the horizontal joiner 5 and the vertical joiner 6 are housed in the fore-edge 10 provided on the back surface of the front plate member 2. As a result, the upper and lower water leakage prevention members 1 'and 1 "are joined. The surface plate member 2 of the joiner
The side end does not appear on the inner wall. Further, the length of the material forming the water passage 3 ′ is shorter than the surface plate member 2 by the thickness of the joiners 5 and 6 . Thereby joined
Joint of the surface plate member 2 in the state is improved,
Leakage to the inner wall surface without the rubber packing grayed can be prevented. Also , the horizontal joiner 5 drains (indicated by an arrow)
In order to obstruct the discharged water, a joiner having a hole as shown in FIGS. 4 to 7 is used. The vertical joiner 6 does not need to have a drain hole.
No. As leakage experiment, Form H Joiner 6 of the vertical joiner 2, the transverse joiner with improvements H type Joyner 7 H-shaped joiner 5 and 3 in Figure 1. This joiner
7 is obtained by extending the upper rise 7 'facing the front surface plate member 2. Correspondingly, the edge of the surface plate member 2
10 is also increased. For comparison, the vertical and horizontal joints also include the conventional structure shown in FIGS . In addition, as shown in FIG. 10,
Plywood 11 and water leakage prevention plate 1 instead of concrete casting
Were spaced and sand 12 was placed between the plywood to make a test wall. Then, water was allowed to flow in at a rate of 10 liters / minute from the upper end of the wall. Even after one hour, there is no leakage from the joint
In addition, it was shown that no water leakage was caused by forming a water leakage prevention wall using the joiner of the present invention.

[0006]

According to the present invention, by the structure coupling member for connecting the inner wall configuration member does not appear on the surface of the inner wall configuration member, the appearance of the inner wall surface better, also, back
Make the length of the face member short according to the thickness of the joiner.
Of the surface member when joining the water leakage prevention member.
Improves tightness and prevents water leakage even without rubber packing.
Can be prevented and the construction can be inexpensive .
