Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a method for making sharp joints in the side walls of buildings or structures.

Traditionally, exterior walls are finished by spraying cement, stone powder, or other spraying materials onto the side walls, but joints are often carved to accent the finish or create patterns. When cement or stone powder is used as a spraying material, it hardens rapidly, so simply removing the joint bar will provide a clear joint, and the area around the joint will not collapse. However, recently, a variety of spraying materials such as synthetic resin paints, inorganic polymer spraying materials, and colored stone powder are often used as spraying materials for exterior walls, and such spraying materials have the same properties as cement. It does not solidify quickly and takes time to finish, and over time, the joint rod will become embedded in the joint area, and if you forcefully remove the joint rod after it hardens, the surrounding side walls along the joint will be damaged. They often collapsed along with the joints, causing undesirable damage to the wall surface. The present invention provides a construction method that does not cause any damage to the joints by using simple steps. Next, an embodiment of the present invention will be described with reference to the accompanying drawings.

1 in Fig. 1 is a joint rod with a specified width used when creating joints on the side walls of buildings;
As shown in FIG. 2, the whole is wrapped with a vinyl resin film 2 along its longitudinal direction, and the upper part is temporarily fixed 3. As shown in FIG. 3, the joint bar 1 thus constructed is directly pressed against the wall base surface 4 of the building, and the spraying material 5 is sprayed to a desired thickness on the entire surface including the joint bar.

FIG. 5 is a sectional view showing a state in which the entire base surface 4 is covered with the spray material 5 and the joint bar 1 is similarly embedded. When taking out the joint bar 1, the spray material 5' built up on the upper surface of the joint bar 1 is gently removed by hand, and the part of the film 2 along the trace is cut with a sharp cutter to take out the joint bar 1 inside. (FIG. 6) Furthermore, by removing the film that binds the joint bar, it is possible to obtain a joint 6 with a clear outline without deformation, as shown in FIG. 7.

As described above, according to the method of the present invention, the joint rod is first wrapped in a synthetic resin film, the film is pressed against the joint area, and the spraying operation is performed, and then the film is cut with a cutter and the joint rod inside is removed. The film part is then removed, but since the synthetic resin film surrounding the joint bar is smooth and the spray material does not stick, it can be removed extremely easily without damaging the surrounding area. Can be done.

As described above, according to the present invention, excellent effects can be obtained such as a sharply defined joint can be obtained and the finishing work on the side of a building can be completed by simply using a joint rod stuffed with a synthetic resin film.

Claims (1)

[Claims] 1. When cutting joints on the finished surface of an exterior wall, wrap the joint rod in a synthetic resin film and place it on the finished surface, spray the exterior wall material onto it, cut the wrapping film, take out the joint rod, and then wrap the above film. A method for removing and forming sharply defined joints.
