Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial application field> The present invention relates to a watertight joint material to be inserted into a joint formed at a joint of an outer wall panel of a building.

<Prior Art> Conventionally, a watertight joint material to be inserted into a joint formed at a joint of an outer wall panel of a building is, as shown in FIG.
The backing material 7 is superimposed on the frame material 1 side and the caulking material 8 is superimposed on the outer side of the joint 3 formed at the abutting portion of the outer wall panels 2 and 2 which are stretched on the outer surface.

However, this conventional watertight joint material comprises a number of steps such as application of a primer, application and removal of a masking tape, installation of a backup material 7, injection and finishing of a caulking material 8, and the construction work is a heavy chain. It is bulky and cannot be constructed during rainfall. Furthermore, the appearance and water tightness of the caulking material 8 are poor due to the adhesion of dust and the like until the caulking material 8 hardens and the occurrence of cracks over a long period of time. There is a problem.

<Problems to be solved by the present invention> Since the conventional watertight joints have the above problems,
It is expected that a watertight joint material which is easy to construct, requires less man-hours, has excellent appearance, and retains the water-stopping function for a long period of time.

An object of the present invention is to provide a watertight joint material that has solved the above-mentioned problems.

<Means for Solving the Problems> A description will be given with reference to the drawings. To achieve the above objectives,
The watertight joint material according to the present invention is to be inserted into joints 3 formed at the abutting portions of the outer wall panels 2, 2 stretched on the outer surface of the frame material 1. It is made of a sealing material 5 for improving the watertightness of the joint material body 4,
The joint material body 4 includes a surface portion 4a that covers the protrusions of the outer wall panels 2, 2 and a leg portion 4b, at least a pair of waterproof lip portions 4c elastically contacting the side end portions of the outer wall panels 2, 2, and a leg portion 4b. The sealing material 5 is formed in a rectangular cross section, and the three surfaces are covered with a coating material 6 which is different from the joint material body 4 and is damaged when subjected to pressure. The joint end body 4 and the sealing material 5 are joined together by aligning the back end face 4d of the joint 3 with the surface 5a of the sealing material 5 that is not covered with the covering material 6, and pressing the joint material body 4 into the joint 3. When it is attached, it comes into pressure contact, and the coating material 6 is damaged and the sealing material 5
Are formed so as to fill the gap of the joint 3.

Preferably, the sealing material 5 is made of unvulcanized butyl rubber.

<Operation> The present invention is configured as described above. In particular, since three surfaces of the rectangular cross section of the sealing material 5 are covered with the coating material 6, the sealing material 5 protrudes when the joint material 3 is loaded, and unnecessary portions are formed. It is easy to attach without adhering to the joint material. When the joint material main body 4 is pushed in and bottomed on the frame material 1, the covering material 6 is damaged and the sealing material 5 fills the gap of the joint material 3. In addition, in combination with the joint material main body 4, a double high watertight effect is exhibited.

In addition, by using an unvulcanized butyl rubber having high adhesiveness for the sealing material 5, the holding force of the joint material to the joint 3 can be increased.

<Examples> Examples will be described with reference to the drawings.
2 and 2 are butted against the outer surface of frame 1
Reference numeral 3 denotes a joint formed at the abutting portion of the outer wall panels 2,2.
The joint material main body 4 having flexibility and the sealing material 5 for improving the water tightness of the joint material main body 4 are constituent members of the watertight joint material of the present invention to be loaded into the joints 3, respectively. 4 is a surface portion 4a coated with rubber or rubber-like elastic material of the same color as the outer wall panels 2, 2, a leg portion 4b whose surface is coated with rubber or rubber-like elastic material like the surface portion 2,
And extend from the leg 4b toward the end face of the outer wall panel 2, 2,
The sealing material 5 is formed to have a rectangular cross section, of which three surfaces are covered with a coating material 6 that is damaged when subjected to pressure, and the sealing material 5 is formed at the back of the joint 3 of the joint material main body 4. The joint material main body 4 and the sealing material 5 are joined together so that the side end surface 4d and the surface 5a of the sealing material 5 which are not covered with the coating material 6 are joined together.

Next, the operation will be described. The watertight joint material according to the present invention covers three sides of the rectangular cross section of the sealing material 5 with the covering material 6, and when the joint material 3 is loaded, the sealing material 5 does not protrude and adhere to unnecessary portions. It is easy to install, and the jointing material main body 4 is pushed in and bottomed on the frame material 1, so that the covering material 6 is damaged and the sealing material 5 is damaged.
Are filled in the gaps of the joints 3, and together with the joint material main body 4, exhibit a double high water-tight effect, so that the appearance and the water-tightness are significantly improved.

By using an unvulcanized butyl rubber having high adhesiveness for the sealing material 5, the holding force of the joint material to the joint 3 is increased.

<Effects of the Invention> The present invention is configured as described above.
Numerous processes such as application of a primer, attachment and removal of a masking tape, attachment of a backup material 7, injection and finishing of a caulking material 8 which were found in conventional products are simplified at a stroke, and the construction work is significantly simplified. The number of man-hours is reduced, construction is possible even during rainfall, and after construction, there is no adhesion of dust and the like, the durability is high, the appearance and watertightness are remarkably improved without cracking for a long period of time.
