Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dry joint gasket integrally attached to an end surface of an outer wall board constituting an outer wall portion of a building in a pre-attached state, and a mounting structure thereof.

[0002]

2. Description of the Related Art For example, as shown in FIG. 12, in the outer wall portion of a house having a steel frame structure, prefabricated panel units U are arranged with a gap 31 of about 80 mm between them. The space 31 is covered with the sealing outer wall board B for construction. Fixing fittings 32 are integrally attached to both ends of the back surface of the sealing outer wall board B, and by fixing the fixing fittings 32 to a steel frame 33 constituting the panel unit U via screws 34, The sealing outer wall board B is fixed to the panel unit U.

Therefore, two joints 35 are formed between the sealing outer wall board B and the outer wall boards B'constituting the panel units U on both sides of the sealing outer wall board B.
Caulking 6 Thus, the two joints 35 are formed on both sides of the sealing outer wall board B, and each joint 35
Since the filler 36 is caulked, the number of steps is large. On the other hand, a method of inserting a gasket instead of caulking the filler 36 on the joint 35 can be considered, but in this method, the gasket is attached (inserted) afterwards and the sealing outer wall board B is attached. It is difficult to meet the demand for adding a function such as fireproofing or waterproofing to the gasket itself, as well as taking another man-hour.

[0004]

SUMMARY OF THE INVENTION In view of the above problems, the present invention provides a dry joint gasket which can be attached to an outer wall board in advance, and can also have a fireproof / waterproof function as required, and a mounting structure thereof. It is an issue.

[0005]

In order to solve this problem, the means adopted by the present invention is through a fixing metal fitting attached to the back surface of the outer wall board and a clip engaged and fixed to the fixing metal fitting. The dry joint gasket can be integrally attached to the end surface of the outer wall board.

Since the dry joint gasket according to the present invention is constructed so as to be integrally attached to the end surface of the outer wall board via the fixing metal fitting attached to the back surface of the outer wall board and the clip engaged and fixed to the fixing metal fitting. Since the gasket can be attached in advance and the outer wall boat is simply attached to the outer wall portion of the building, the gasket is inserted into the joint to be formed, so that the number of steps for constructing the gasket is reduced.
Also, by making the fixing metal fitting attached to the back surface of the outer wall board into a strip plate shape, extending this in the width direction, and projecting from the end surface of the outer wall board by using the extended portion as a fire protection protrusion. , Add a fire protection function to the gasket,
Furthermore, a waterproof function can be added to the gasket by attaching a waterproof lip to the back surface of the fireproof protrusion of the fixing bracket.
