Description

Connecting plate for water proofing using in concrete structure} Connected member for water proofing part installed to prevent leakage of concrete structure and expansion joint part of expansion joint part

The present invention is an expansion joint member (expansion joint member) formed of synthetic resins or rubber plates used to prevent leakage of construction joints of concrete structures, especially metals, and inserted at regular intervals to prevent collapse of concrete structures. And a water plate connecting member used for the connecting portion with the expansion joint member).

Concrete structures such as foundation basements, slab subwalls, dams, embankments, tunnels, underpasses and reservoirs are constructed to be waterproofed by installing water-damp plates in the walls of concrete structures to block water from the outside. have.

Conventionally, metal plates, especially copper plates, have been used to prevent leakage of concrete structures. However, copper plates have high strength and poor corrosion resistance, which has a long-lasting advantage, but they are too expensive and costly to construct. With the development of the synthetic resin industry, soft vinyl chloride (PVC) or rubber materials are extruded to produce various index shapes, for example corrugated type cross sections. In addition, it is possible to bring a perfect exponential effect by strengthening the binding with concrete. In recent years, it is very inexpensive compared to copper plates (less than 1/10 of copper plates) and has high leakage blocking effect. Easy synthetic resin index plate is mainly used for waterproofing concrete structures.

On the other hand, the concrete structure is relatively vulnerable to thermal expansion, so to prevent the collapse of the structure is prescribed to be installed through the expansion joint member (expansion joint member, expansion joint member) formed of a metal material at regular intervals.

Accordingly, when constructing a concrete structure such as a building, as shown in Figure 5, in the concrete wall 20 to be raised from the basement to the ground, the index plate 21 is buried in a line to prevent leakage, concrete In the case of the structure, it is not placed continuously, but it is spaced at a certain distance (20 ~ 30m), and then it is installed (H), and the expansion joint member (: copper plate) 22 is buried at the boundary point therebetween to expand the expansion. Since it is absorbed, the index plate 21 meets the expansion joint member 22 on the way.

However, in order to prevent leakage at the connection portion where the water stop plate 21 and the expansion joint member 22 meet, the above-described two side members 21 and 22 must be integrated, and the water discharge plate 21 is made of plastic and the expansion joint member Since 22 is a metal material and has no affinity for each other and welding is impossible, the gap between the two side members 21 and 22 is sealed with a sealant 23, which is a sealing agent, to eliminate the gap in the related art.

However, in the case of the sealing treatment by the sealant 23, when the hydraulic pressure is applied, the application portion of the sealant 23, which is the weakest portion, is broken, and water leaks through the sealant. 23) is easily broken and the problem of leakage of the connection portion between the index plate 21 and the expansion joint member (: copper plate) 22 has been a long unsolved problem in the industry.

The present invention has been proposed in view of the above point, and its purpose is to leak water at the connection part of the expansion joint member (copper plate), which is made of a synthetic resin material or rubber material used to prevent leakage of concrete structures, and a metal material. It is possible to prevent, and to provide a spout plate connecting member for the connection of the index plate and the expansion joint member that can ensure the stability of the connection even if deformation, such as ground subsidence or distortion of the concrete wall occurs.

According to claim 1 of the present invention for achieving the above object, the index plate of the synthetic resin material embedded in the wall for preventing leakage of the concrete structure, the index plate in the index plate used for the portion connected to the expansion joint member of the metal material, One end is embedded in the body of the other end is extended so as to be exposed to the outside of the body of the index plate, characterized in that it comprises a metal plate weldable to the expansion joint member through the exposed end.

According to the second aspect of the present invention, a plurality of holes are formed in the embedding portion of the metal plate on the still water plate, and both side surfaces of the still water plate covering the embedding portion are integrally connected through the hole.

According to the third aspect of the present invention, an end portion of the exposed portion of the metal plate is provided with a flange for increasing a close cross-sectional area with the expansion joint member.

4 is a view showing a state in which a water plate and an expansion joint member are connected by using the water plate connecting member of the present invention.

In Fig. 1, the index plate connecting member is denoted by reference numeral 1, and the index plate connecting member 1 is composed of an index plate 2 and a metal plate 3, which are non-metallic materials, and the metal plate 3 is connected to the index plate 2 at one end thereof ( 3a) is injection molded.

The index plate 3 is made of synthetic resin or rubber material, in particular, PVC (vinyl chloride resin), which is a high polymerization resin, and the metal plate 3 is made of the same material as the expansion joint member 4, for example, a copper material having high corrosion resistance. It is formed.

The metal plate 3 has one end thereof, i.e., the buried portion 3a, is embedded in the body of the water plate 2, and the other end thereof, the exposed portion 3b, extends out of the body of the water plate 2 and remains exposed. do.

In the insert injection molding of the metal plate 3 into the body of the index plate 2, since a plurality of holes 5 are formed in the buried portion 3a of the metal plate 3, the molten synthetic resin fills the holes 5. Both sides 3c and 3d of the receiving plate 3 are integrated by the connection part 6 which fills the hole 5 so as to surround both sides of the buried portion 3a. Even if 3) is pulled in the opposite direction, the connection part 6 is prevented from falling out of each other.

On both sides 3c and 3d of the index plate 2, a plurality of locking projections 7 protrude side by side from the surface, and a hollow core-shaped core material 8 is continuous in the horizontal direction at the center thereof.

Meanwhile, as shown in FIG. 4, when the index plate 2 and the expansion joint member 4 are connected, the insert-injected metal plate 3 and the expansion joint member 4 are joined to each other so that the gap is sealed by welding. At this time, in order to increase the connection force and the sealing force, the flange joint 9 is placed on the end portion of the exposed portion 3b of the metal plate 3 so as to overlap with the expansion joint member 4 so as to increase the adhesion cross section. 4) and then weld.

According to the present invention as described above, since the index plate 2 and the index plate (2, shown by a dashed line) are the same plastic material (PVC), the welding (10) by PVC welding with each other is possible, and can be installed continuously without gaps. In general, the water plate connecting member (1) is used for the portion that meets the expansion joint member (4) which separates the concrete structure at intervals of 30 m and installs therebetween. When the flange portion 9 of the metal plate 3 protruding to one side is matched with the expansion joint member 4 and then integrated by welding 10a, the connection is made with rigidity compared to the conventional sealant sealing method. Therefore, leakage through the connection part can be completely prevented.
