Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for caulking joints on wall surfaces constructed of foam concrete panels, a caulking member used in the caulking method, and a method for manufacturing the caulking member. .

[0002]

2. Description of the Related Art Conventionally, when caulking joints on wall surfaces constructed of foamed concrete panels, etc., a caulking material is conventionally filled by using a filler that allows the caulking material to be twisted out by pulling a lever. Then
I was doing finishing work such as preparing the surface of caulking material with a spatula.

[0003]

However, according to the conventional method, a large number of joints are caulked manually, and an unskilled person does not have a uniform filling amount of caulking material, and the finishing work is reliable. Since it could not be done, it required skill, it took days to implement it, and the cost was significantly increased due to lack of skilled personnel and soaring personnel costs. Under these circumstances, there is a demand for a joint caulking member that can be easily applied. For example, a soft resin filling having a lip portion may be considered, but the sealing property is insufficient, and caulking that has been conventionally used has been desired. The material is said to be the best.

The first object of the present invention is to eliminate the above-mentioned drawbacks of the conventional caulking means and to use a conventional caulking material excellent in sealing property, to easily, quickly and accurately without the need for skill. An object of the present invention is to provide a caulking method for joints capable of caulking. A second object of the present invention is to provide an optimum caulking member to be used in such a caulking method. A third object of the present invention is to provide a method for manufacturing a caulking member that can easily manufacture the above caulking member.

[0005]

The caulking method for joints according to the present invention is a caulking member in which a caulking material is filled and sealed in a tube made of a soft synthetic resin which has a twisting opening on a side surface and seals the twisting opening. While opening the seal of the caulking member, the caulking member is packed in the joint so that the twisted outlet side faces the inner wall direction of the joint, and the caulking member is crushed from the surface side by a jig or the like. This is a method in which the caulking material is twisted out from the twisting opening to fill the inner part of the joint and the tube is left in the joint as it is.

The caulking member according to the present invention is provided with a twist-out port on a side surface of a tube made of a soft synthetic resin, and the twist-out port is openably sealed. Is configured by sealing. As the structure of the twist-out port, one or more rows of holes may be provided on the side surface of the tube along the lengthwise direction and the holes may be covered with a seal tape. Alternatively, the slit-shaped twist-out port may be formed by integrally molding and peeling the peelable portion. In this case, the peelable portion may be integrally formed with the tube body with a resin material that is harder than the tube body, and the peelable portion may be provided with a tab.

The first method of manufacturing a caulking member according to the present invention is to extrude a tube from a soft synthetic resin, flatten the tube, and make one side edge of the tube along the lengthwise direction of the sewing machine. By forming a large number of holes such as by forming a twisting opening consisting of two rows of holes in the tube,
This twisting opening is closed with a peelable seal tape, one end of the tube is sealed, a caulking material is injected from an opening on the other end, and then the opening is sealed.

The second method is a peelable portion in which a slit-like twisted opening is formed on the side surface of the tube when the tube is extruded from a soft synthetic resin and is extruded from the tube. Is integrally molded, the one end side of the tube is sealed, the caulking material is injected from the opening part on the other end side, and then the opening part is sealed. In this case, it is also possible to use a mold shape such that a knob is formed on the peelable portion, and use a molding material of the peelable portion as a hard or semi-rigid material and perform two-color extrusion with the soft resin material of the tube body. .

[0009]

In the production of the caulking member, the tube extruded from the soft synthetic resin is flattened, and one side edge thereof is provided with a large number of holes along the lengthwise direction by a sewing machine or the like so that the tube is formed into a flat shape. Form a twist-out port consisting of holes in a row, attach a peelable seal tape so as to block this twist-out port, seal one end of the tube, and then inject caulking material from the opening on the other end Then, the opening is sealed.

Alternatively, when a tube is extruded from a soft synthetic resin, a two-color extrusion is used to separate the tube from the tube so that a slit-like twisted opening is formed on the side surface of the tube. The separable portion made of the resin material is integrally molded, one end side of the tube is sealed, the caulking material is injected from the opening portion on the other end side, and then the opening portion is sealed.

The caulking member manufactured as described above has a twist-out port formed on the side surface of a soft synthetic resin tube, and the twist-out port is openably sealed, and the caulking material is filled inside. In addition, both ends of the tube are sealed.

When performing caulking of joints, the seal of the caulking member is opened from one end side, and the caulking member is packed in the joint so that the twisting opening side appearing by opening the seal faces the inner wall of the joint. The caulking member is crushed from the surface side by a jig or the like, and the caulking material is twisted out from the twisting opening. As a result, the caulking material is filled in the inner part of the joint, and moreover, the caulking material can be uniformly filled without excess or shortage. Further, the tube remains in the joint as it is, and the surface treatment of the caulking portion is unnecessary.
