JPS6125669A - Method for filling caulking material into joint part of facing material - Google Patents

Abstract

PURPOSE:To prevent the bulging out of a caulking material onto a facing material and to improve the operability by filling the caulking material into a joint part, and surface-finishing with use of a masking agent. CONSTITUTION:A masking agent 3 is coated on the surface of a facing material 1 in the vicinity of a joint part 2 with a coating roller 9 such as a roller sponge to form a protective film 11. Then a caulking material 4 is filled into the joint part 2 from a nozzle 12, the surface of the caulking material 4 is pressed with a finishing jig 6 such as a pallet, and the surplus caulking material 4 is scraped off. The protective film 11 and the caulking material 4 deosited on the film are then released from the surface of the facing material 1 by using a releasing rubber roller.

Description

Detailed Description of the Invention [Technical Field J] The present invention relates to a method of filling caulking material into the joints of exterior materials when filling the joints formed between a pair of exterior materials. .

Background technology J Conventionally, caulking material is filled in the joints formed between exterior materials to absorb expansion and contraction due to thermal expansion of the exterior materials at the joints and to ensure waterproofness between the exterior materials. It is being done. Conventionally, when filling caulking material into the joints of exterior materials, the caulking material was discharged from the nozzle of a caulking material dispensing device into the joints, and then the surface of the caulking material was pressed down using a finishing jig such as a Hef. The surface was smoothed and excess caulking was scraped off. However, when finishing the surface of the caulking material with a finishing coat, the caulking material protrudes from the joints and stains the surface of the exterior material.

[Object of the Invention] The present invention has been made in view of the above points, and it is possible to prevent the caulking material from protruding from the joints of the exterior material when finishing the surface of the caulking material, and to fill the caulking material with the filling material. It is an object of the present invention to provide a method of filling caulking material into joints of exterior materials, which can improve accuracy and workability.

[Disclosure of the Invention] In other words, method #X1 of filling the joints of the exterior material with caulking material according to the present invention involves filling the joints of the exterior material 1 in the vicinity of the joints 2 formed between the end faces of the pair of exterior materials 1.1. Masking agent 3 is applied to the surface, then caulking material 4 is filled in the joints 2, and then the surface of the caulking material 4 is finished with a finishing jig 6, and then the masking agent 3 is peeled off from the surface of the exterior material 1. The surface of the exterior material 1 at the joint part 2 is protected in advance with a masking agent 3 to prevent the caulking material 4 protruding from the joint part 2 from directly adhering to the surface of the exterior material 1, I'm satisfied with something that achieves the above objectives.

The present invention will be described in detail below based on examples. As shown in FIG. 1, the pair of exterior materials 1.
is fixed to form an outer wall panel 8. Exterior material 1
When filling the caulking material 4 into the joint 2, as shown in FIG. 1, the masking agent 3 is first applied to the surface of the exterior material 1 in the vicinity of the joint 2. This masking agent 3 is a temporary protective paint of acrylic emulsion type and is commonly called stripper pull paint.
When this material is applied to the surface of the exterior material 1, it quickly forms a lubricating film 11, which protects the surface of the exterior material 1 and at the same time facilitates axis separation.

This masking agent 3 can be applied by spraying, brushing, or roller coating, but it is preferable to apply it with a roller 9, such as a roller bonnet, as shown in the figure. Next, the caulking material 4 is filled into the joint part 2 through the nozzle 12, and then the surface of the caulking material 4 is pressed down using a finishing jig No. 6 such as a spatula, and at the same time, the excess caulking material 4 is scraped off. Next, after the masking agent 3 is cured to form the protective film 11, it is held using a peeling rubber roller 10! 1 film 11 and 1 caulking material 4 are peeled off from the exterior material 1 surface. By rotating and moving the rubber roller 10 on the exterior material 1, the rubber roller 10 can be secured around the rubber roller 10!
The film 11 is attached, and it is preserved! The film 11 can be wound up.

By applying the masking agent 3 to the surface of the exterior material 1 near the joints 2 and then filling the joints 2 with caulking material 4 to finish the surface, the surface of the exterior material 1 is masked. The caulking material is immediately applied to exterior material 1 after being protected by agent 3.
It does not adhere to the surface, and by subsequently peeling off the masking agent 3 from the surface of the joint 2, the caulking material 4 protruding from the joint 2 can be removed. In particular, by applying the masking agent 3 using the coating roller 9 and peeling it off using the peeling rubber roller 10, the coating and peeling operations of the masking agent 3 can be performed extremely easily. The above-mentioned method is particularly suitable for applying caulking material in a factory, and allows the caulking material work to be carried out efficiently and the productivity of the outer wall panel 8 to be improved.

[Effect of the invention 1 As described above, the present invention applies a masking agent to the surface of the exterior material at the opening edge of the joint, then fills the joint with caulking material, and then coats the surface of this caulking material with a finishing coat. After finishing, the masking agent was peeled off from the surface of the exterior material, so the caulking material was scraped off while the surface of the exterior material was protected by the masking agent, and then the masking agent was peeled off from the exterior material. By removing the protruding caulking material at the same time, the surface of the caulking material can be smoothed without the caulking material protruding from the joints, and there is no need to remove the caulking material in post-processing as in the past. This not only improves work efficiency but also improves filling accuracy.
