Abstract

(57) [Summary] [Purpose] To perfectly waterproof vertical joints in joints of outer walls of buildings. [Structure] On an outer wall of a building constructed by laminating extruded cement boards 1, the longitudinal cross-sections are connected by actual joints and the cross-shaped cross-sections 2 are filled with a sealing material. In addition, a U-shaped water receiver 4 is inserted into the vertical joint 3 with the opening side being the front side, and the support piece 5 is inserted into the hollow portion 1a of the extrusion molded cement plate 1 so that the water receiver 4 is deep inside. Prevents entry to the side. Further, the rubber packing 4a attached to the tip of the water receiver 4 is pressed against the extrusion molded cement plate 1 in a watertight manner to seal between the water receiver 4 and the extrusion molded cement plate 1, and the joint on the opening side. Is filled with the sealing material 6.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a waterproof structure in a joint portion of an outer wall of a building.

[0002]

[Prior art]

 In general, the extruded cement board is formed by actual processing in the longitudinal direction and flat processing in the lateral direction. Therefore, when constructing the outer wall of the building by the horizontal lining method using the extruded cement board, as shown in Fig. 6, the horizontal joint 10 side is the actual joint, and the vertical joint 20 side is the sealing material 30, respectively. Prevents rainwater from entering.

[0003]

[Problems to be solved by the device]

 However, in the above configuration, only the sealing material on the vertical joint side prevents rainwater from entering.Therefore, if the building shakes or the sealing material dries and shrinks, a gap will form in the vertical joint and rainwater will enter. If rainwater invades, it is impossible to predict where it will move, it is difficult to find the defective part of the sealing material, repeated repairs are required, and the mounting base metal can be corroded There are various problems, such as The present invention has been made in view of such a problem, and an object thereof is to completely waterproof vertical joints in joints of an outer wall of a building.

[0004]

[Means for Solving the Problems]

 The waterproof structure at the joints of the outer wall of the building of the present invention to achieve the above-mentioned object is a state in which the water receiver whose front end side is expanded is in pressure contact with the inner wall of the joint in the vertical joint of the outer wall where the molded cement plates are laminated The bottom end of the outer wall is brought into contact with the draining metal fitting, and the front side of the vertical joint is closed with a sealing material.

[0005]

[Advantages] According to the above configuration, all rainwater that has entered the vertical joint is flown downward by the water receiver and is drained by the draining metal fitting at the bottom of the outer wall. In addition, since this water receiver is pressed against the inner wall of the joint to maintain its watertightness, rainwater will not intrude inward and will not corrode the underlying metal fittings.

【Example】

 Hereinafter, an embodiment of a support for a suspended ceiling according to the present invention will be described in detail with reference to the drawings. 1 is a perspective view of a building using the waterproof structure of the present invention, FIG. 2 is a sectional view of the waterproof structure, and FIG. 3 is a cutaway perspective view of the waterproof structure.

The outer wall of the building shown in FIG. 1 is formed by laminating extruded cement boards 1. The extruded cement boards 1 are connected in the longitudinal direction by actual joints, and the horizontal cross-sections 2 are filled with a sealing material. There is.

In addition, a U-shaped water receiver 4 is inserted into the vertical joint 3 with the opening side facing forward, and the supporting piece 5 is inserted into the hollow portion 1 a of the extrusion molded cement board 1 to receive the water. It prevents the tool 4 from entering the back side.

Further, the rubber packing 4a attached to the tip of the water receiver 4 is pressure-contacted to the extruded cement plate 1 in a watertight manner to tightly seal the space between the water receiver 4 and the extruded cement plate 1 and to open the opening. The joint material on the part side is filled with the sealing material 6.

The water receiver 4 is made of vinyl chloride resin and has an appropriate length, and the support piece 5 is adhered to the back surface of the water receiver 4 in a state of being expanded rearward. Then, as shown in FIG. 3, the water receivers 4 are continuously connected in the longitudinal direction and are fitted into the vertical joints 3, and the lowermost ends thereof are brought into contact with the draining metal fittings 7 at the lowermost part of the outer wall. There is.

Therefore, even if water enters the vertical joints 3, the water is flowed downward by the water receiver 4 and drained from the drainage metal fitting 7 at the lowermost part of the outer wall, so that the water further invades. Prevent.

To attach the water receiver 4 to the vertical joint 3, as shown in FIG. 5, the support piece 5 is manually pinched and inserted into the vertical joint 3 in a state of being narrowed inward. Then, the support piece 5 is expanded and locked in the hollow portion 1a of the extrusion-molded cement board 1, so that the water receiving fitting 4 is fixed without further entering.

[0013]

[Effect of device]

 In the vertical joint of the outer wall where the molded cement plates are stuck together, the water receiver with the expanded tip side is inserted in pressure contact with the inner wall of the joint, and the lower end of the water receiver is abutted on the draining metal fitting at the bottom of the outer wall, Even if water leaks into the vertical joint due to the sealing material contracting or deteriorating due to the front side being blocked by the sealing material, it is stopped by the water catcher and the outermost wall Since the drainage from the drainage fittings in the building is treated, the vertical joints in the joints of the outer wall of the building can be completely waterproofed.

Claims (1)

[Scope of utility model registration request] 1. A water receptacle whose front end side is expanded is fitted in a vertical joint of an outer wall to which a cemented cement plate is adhered, in a state of being in pressure contact with the inner wall of the joint, and its lower end abuts on the draining metal fitting at the lowermost part of the outer wall. The waterproof structure in the joint portion of the outer wall of the building is characterized in that the front side of the vertical joint is closed by the sealing material.
