Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a method for connecting and constructing exterior wall materials, and in particular, to a method for connecting and constructing external wall materials, and in particular, to form steps or grooves in the form of serrations, square grooves, round grooves, waves, etc. extending horizontally on the surface. The present invention relates to a novel method for connecting external wall materials on which walls are formed at arbitrary locations such as wall corners or horizontal joints.

<Prior art> Extruded building materials, especially ceramic extruded building materials, are produced by continuous extrusion molding, so long sizes can be easily obtained, the shape in the length direction can be set to desired lengths, and fire prevention is achieved. In recent years, it has come to be used in large quantities as a building material for the exterior walls of houses because it has excellent performance, is lightweight, and can improve C1 and thermal properties by providing a hollow section inside.

On the other hand, one of the recent Western-style exteriors! Due to the current trend, a variety of so-called siding exterior wall materials with horizontally extending steps or grooves formed on the surface are provided, mainly ceramic extruded building materials.

Including the above-mentioned siding-finished exterior wall materials, in house constructions using ceramic-based exterior wall materials, there is a protruding corner.

The corner structure is formed using joiners for extended corners and large corners made of metal or synthetic resin, which have hollow parts at both ends for inserting and fitting the ends of the external wall material at the inside corners.

In addition, when horizontally joining such external wall materials within the wall surface, use an H-shaped, ■-shaped, etc. joiner to similarly insert and fit the ends of the external wall materials into the hollow portions at both ends to perform the horizontal joint. ing.

<Problems to be Solved by the Invention> However, when the above-mentioned siding-finished external wall materials are connected using the above-mentioned joiners at wall corners and horizontal joints, the joints between the surface steps or grooves of the external wall materials and the joiner
A gap is formed between the joiner and the joiner, and moisture and the like can enter through this gap, causing problems with the joiner's durability, such as rusting and discoloration over time.

In order to prevent this, caulking or sealing material is sometimes filled into the gap after inserting the exterior wall material into the joiner, but the shape of the gap is 'l;i'.
Because of the rain, it took time and effort to construct it, and it was difficult to obtain a sufficient waterproof effect.

Furthermore, the gap between the exterior wall material and the joiner hinders the ability to provide a beautiful exterior to the corner of the wall.

Means and operation for solving the space problem> Therefore, the present invention was devised in order to provide a new method for connecting and constructing external wall materials that has an excellent waterproof effect and is also effective for surface decoration. Using a joiner, which has hollow portions at both ends, and is configured to accommodate the ends of the outer wall materials in the hollow portions, the outer wall materials each having a step or a groove extending in the horizontal direction are formed on their surfaces. Therefore, when connecting at any point on the wall surface, due to the presence of a step or groove on the surface of the exterior wall material between the end of the exterior wall material accommodated in the hollow portions at both ends of the joiner and the joiner. This method is characterized in that a tape-shaped sealing material having a cross-sectional shape corresponding to the cross-sectional shape of the above-mentioned external wall material is press-fitted into the formed step-like or groove-like gap. .

The sealing material restores itself after being press-fitted into the joiner due to its compressive restoring force and completely fills the gap between it and the exterior wall material, and 10. Effectively prevents moisture from entering through the gaps.

<Example> Fig. 1 shows an example of exterior wall construction by the method of the present invention, in which pillars 11 and studs 12 are driven onto a foundation 10, and a waterproof sheet 13 such as asphalt felt attached to these pillars and studs is placed. It is made up of a large number of exterior wall materials 20 laid horizontally.

The cross-sectional shape of the exterior wall material 20 constituting the wall surface in FIG. 1 is as shown in FIG. A self-determined fruit portion 21 is formed.

The connecting construction of the external wall material 20 at the large corner A of the wall surface in FIG. 1 is as shown in FIG. Then, by inserting and fitting the ends of the exterior wall materials 2o into both open ends of the joiner 30, and then nailing each exterior wall material 20 to the studs, the exterior wall materials 20 are connected to each other. is doing.

In the method of the present invention, as shown in FIG.
Exterior wall material 20 housed in joiner 30 and joiner
A tape-shaped sealing material 40 having a cross-sectional shape that can completely fill the step-like gap formed between the outer wall material 20 and the outer wall material 20 in correspondence with the serrated surface steps.
This is the filling work.

Is the sealing material 40 rubber-based or synthetic I? It is made of a material that is waterproof, elastic, and has compression resilience, such as a lubricant type or a synthetic resin foam type. The sealing material 40 is attached to the joiner 30 and the exterior wall material 2.
An adhesive layer is provided on the back side of the sealing material 40, which works to completely fill the gap by the restoring force of the pressure wi, which is press-fitted into the gap between the sealing material 40 and the joiner 30. can be increased. Furthermore, the design can be improved by coloring the sealing material, if necessary.

Figure 5 shows the exterior wall material 2 at the corner B of the wall surface in Figure 1.
This shows the connecting construction of the large corner part 0, and the connecting construction of the large corner part shown in FIGS. 3 and 4 is the same as that of the large corner part shown in FIGS. In this case as well, the tape-shaped sealing material 40 having the same shape and material as that used for the large corner portion can be used.

The tape-shaped sealing material 40 can be used in the same way when horizontally joining the exterior wall materials 20 together using a conventionally known H-shaped or I-shaped tank joining joiner at the joint C in the wall surface. It is press-fitted to fill the gap between the exterior wall material and the joiner.

In the above explanation, it is assumed that a material having a plurality of sawtooth-like steps formed in the horizontal direction on the surface as shown in FIG. The exterior wall materials that can be used are not necessarily limited to such specific shapes, but can be shaped as shown in FIG. 6(A).
Even for exterior wall materials having various cross-sectional shapes or surface shapes as exemplified in ~(D), tapes with shapes that can fill the gap with the joiner in response to these complex cross-sectional shapes or surface shapes. Using a shaped sealing material,
Connections can be made at wall corners or horizontal joints.

<Effects of the Invention> In the present invention, when connecting external wall materials having a plurality of horizontally extending steps or grooves formed on the surface at arbitrary locations such as wall corners or rammed joints, the surface steps of the external wall materials are By using a tape-shaped sealing material with a cross-sectional shape that corresponds to the shape of the part or groove and press-fitting it into the gap between the joiner and the joiner, it can be easily installed, and its compressive restoring force completely fills the gap. By filling the joiner, it is possible to provide a significantly superior waterproofing effect and greatly improve the durability of the joiner.The present invention utilizes the joiner that has been used in the past, and also does not require the conventional joiner. Eliminates the need for troublesome caulking material filling work.
