Description

[Detailed explanation of the idea] The present invention relates to a waterproof joint structure for building components.

In the conventional joining structure of building members, as shown in Fig. 1, sealant tape 4' (sponge) was simply pasted on the back of the joint 6' of building member 5'. When the sealant tape 5' is nailed 8' to the mounting member 7', there is a problem that the sealant tape 4' tends to absorb water and lacks waterproof properties as shown in FIG.

The present invention was developed in view of the above points, and its purpose is to have a double waterproof function, and in particular, to achieve an excellent waterproof function by nailing building components to the mounting material. The purpose of the present invention is to provide a waterproof bonding structure for architectural members that can provide excellent performance.

In the present invention, a hot melt adhesive 2 is attached to the adhesive side of a waterproof adhesive tape 1 over the entire length at the center in the width direction, and the adhesive tape 1 has waterproof properties from both sides in the width direction to the adhesive side. A waterproof adhesive tape 4 is formed by protruding elastic lip pieces 3, and double-folded double lip pieces 9 on both sides of the hot melt adhesive 2, which are slanted so that the tip approaches the hot melt adhesive 2 side. , a joint 6 on the back side of the building member 5
At the same time, the hot-melt adhesive 2 of the waterproof adhesive tape 4 is attached to the back of the building member 5 on both sides of the joint 6, and the elastic lip pieces 3 are brought into elastic contact with the back of the building member 5, and the tape 1 is removed from the building member 5 at a position inside the elastic lip pieces 3. This relates to a waterproof joint structure for building members that is formed by penetrating and nailing. A waterproof adhesive tape 4 is disposed on the back side of the joint 6 of the plate-shaped building member 5, and is composed of a waterproof adhesive tape 1 and a hot melt adhesive 2. The tape 1 is made of weather-resistant rubber such as EPT, and both sides of the tape 1 in the width direction are folded over the entire length toward the adhesive side to form elastic lip pieces 3. A hot melt adhesive 2 is attached to the widthwise center of the tape 1 over its entire length. On the adhesive side of the tape 1, between the hot melt adhesive 2 and the elastic lip piece 3, a double lip piece 9 having elasticity and made of the same material as the tape 1 is formed over the entire length. FIG. 3 shows the waterproof adhesive tape 4 bonded to the joint 6 of the building component 5, and the hot melt adhesive 2 is applied to the joint 6.
The elastic lip piece and double lip piece 9 are in elastic contact with the back surface of the building member 5. FIG. 4 shows a state in which the building member 5 is fixed to the mounting member 7 by driving 8 nails, the hot melt adhesive 2 becomes flat and the lip pieces 3 and 9 are bent and deformed. The nail 8 is driven between the lip pieces 3 and 9, and therefore, water from entering through the nail through hole of the tape 1 is blocked by the double lip piece 9 and cannot reach the joint 6. 10
is a stepped part for joint formation.

As described above, the present invention involves attaching hot melt adhesive to the adhesive side of a waterproof adhesive tape over the entire length in the center of the width direction, and applying waterproof adhesive to the adhesive side from both sides of the tape in the width direction. A waterproof adhesive tape is formed by protruding an elastic lip piece having a In addition, since the elastic lip pieces are in elastic contact with the backs of the building components on both sides of the joint, there is an advantage in that a double waterproof structure of the hot melt adhesive and the elastic lip pieces can be obtained. By nailing the waterproof adhesive tape to the building material, the hot melt adhesive flattens due to its own adhesive properties, ensuring waterproofing of the joint, and the elastic lip piece also bends greatly, allowing the tape to adhere to the building material. This has the advantage that the elastic contact force increases, further improving the waterproofness of the double waterproof structure.
Furthermore, elastic lip pieces are brought into elastic contact with the adhesive surface from both sides of the tape in the width direction, and the nails are driven through the tape from the building material at a position inside the elastic lip pieces, so that the tape can be driven through the construction material by nailing. Even if rainwater infiltrates through the nail holes formed in the member, this rainwater is dammed up by the elastic lip piece and can be prevented from infiltrating deep into the back of the building member. Moreover, the double lip pieces on both sides of the hot melt adhesive are slanted so that the tip of the double lip pieces approaches the hot melt adhesive side, so the hot melt can be made with the double lip pieces that get closer to the hot melt adhesive as the tip side approaches the hot melt adhesive. This has the advantage that it is possible to strongly prevent the adhesive from escaping to both sides, and that the hot melt adhesive can sufficiently reach the joint on the back side of the building member.
