Description

TECHNICAL FIELD The present invention relates to a method for connecting outer wall materials, and more particularly to a stepped portion or groove portion having a sawtooth shape, a square groove shape, a round groove shape, a wavy shape, etc. extending horizontally on the surface. The present invention relates to a novel method for connecting and constructing outer wall materials formed with ridges at arbitrary locations such as wall corners or horizontal joints.

<Prior Art> Extruded building materials, especially ceramic-based extruded building materials, are produced by continuous extrusion forming, so long-sized products can be easily obtained, and the shape in the length direction can be set arbitrarily, which improves fire protection performance. In addition to being excellent and lightweight, it can be improved in heat retention by providing a hollow portion inside, so that it has been used in large quantities in recent years as a building material for outer walls of houses.

On the other hand, in order to popularize and popularize Western-style appearance in recent years, various so-called siding-finished outer wall materials having a step portion or a groove portion extending in the horizontal direction on the surface are mainly provided as ceramic-based extruded building materials.

Including the outer wall material of the siding finish, in general, in a house construction using a ceramic outer wall material, a metal having a hollow portion at both ends for inserting and fitting the end portion of the outer wall material at the protruding corner and the inner corner, or The corner structure is formed by using a joiner for entering and entering corners made of synthetic resin or the like. Further, in the case where such outer wall materials are horizontally connected in the wall surface, an H shape, I
Similarly, using a joiner of a shape or the like, the end portions of the outer wall material are inserted and fitted into the hollow portions at both ends, respectively, and the side joint is performed.

<Problems to be Solved by the Invention> However, in the case where the siding-finished outer wall material is connected and constructed by using the joiner at the wall corner or the lateral joint, the surface step portion or groove portion of the outer wall material and the joiner are joined. Since a gap is formed in the gap and moisture or the like penetrates through the gap, there is a problem in durability such as rusting or fading of the joiner over time.

In order to prevent this, after inserting the outer wall material into the joiner, filling the above gap with caulking material or sealing material is also carried out, but the shape of the gap is complicated and it takes time and time for construction, Moreover, it has been difficult to obtain a sufficient waterproof effect.

Further, the gap between the outer wall material and the joiner hinders giving a beautiful exterior to the corners of the wall surface.

<Means and Actions for Solving Problems> Accordingly, the present invention was devised to provide a novel method for connecting and connecting outer wall materials, which has an excellent waterproof effect and can also exert an effect on surface makeup. , Outer wall members having stepped portions or grooves extending in the horizontal direction on the surface thereof, using a joiner configured to have hollow portions at both ends and to accommodate the end portions of the outer wall members in the hollow portions, When performing connection construction at an arbitrary location on the wall surface, a step formed due to the presence of the surface step or groove of the outer wall material between the joiner and the end of the outer wall material housed in the hollow portions at both ends of the joiner. The tape-shaped sealing material having a cross-sectional shape corresponding to the cross-sectional shape of the outer wall material is press-fitted into the groove-shaped or groove-shaped gap and is constructed by a material having waterproofness, elasticity, and compression restoring force. thing Is a method for connecting and constructing outer wall materials.

The sealing material is pressed into the joiner due to its compressive restoring force and then restored to completely fill the gap with the outer wall material and effectively prevent moisture from entering through the gap.

<Example> FIG. 1 shows an example of an outer wall construction by the method of the present invention. A pillar 11 and a stud 12 are driven into a foundation 10 and a waterproof sheet such as asphalt felt attached to the pillar and the stud.
A large number of outer wall materials 20 are laterally lined on the top surface of the base 13.

The cross-sectional shape of the outer wall member 20 constituting the wall surface in FIG. 1 is as shown in FIG. 2, and a plurality of horizontally-saw-toothed stepped portions are formed on the surface. The real part 21 is formed.

The connection construction of the outer wall material 20 at the wall entry corner A in FIG. 1 is as shown in FIG. 3, and the joining corner joiner 30 made of synthetic resin or metal is erected upright along the entry corner. This is done by inserting the ends of the outer wall material 20 into both open ends of the joiner 30 so that the outer wall materials 20 are nailed to the spar posts, thereby connecting the outer wall materials 20 to each other. I am doing it.

In the method of the present invention, next, as shown in FIG. 4, the outer wall member 20 and the joiner housed in the joiner 30 are accommodated.
A tape-shaped sealing material 40 having a cross-sectional shape capable of completely filling the stepped gap formed between the outer wall member 20 and the outer wall member 20 in a stepped gap is filled. It is to be constructed.

The sealing material 40 is made of a material such as rubber, synthetic resin, synthetic resin foam, etc., which is waterproof and elastic and has a compression restoring force. The seal member 40 is press-fitted into the gap between the joiner 30 and the outer wall member 20, and then works to completely fill the gap by its compression restoring force. An adhesive layer may be provided on the back surface of the sealing material 40 to further enhance the adhesion with the joiner 30. If necessary, the seal material can be colored to improve the design.

FIG. 5 shows the outer wall material at the corner B on the wall surface in FIG.
20 shows the connection construction, and is the same as the connection construction at the entrance corner shown in FIGS. 3 and 4 except that the joiner 32 for the exit corner is used, and therefore detailed description thereof will be omitted. Also in this case, the tape-shaped sealing material 40 having the same shape and material as that used in the inside corner can be used.

The tape-shaped sealing material 40 is also used in the lateral joint portion C in the wall surface when the outer wall materials 20 are laterally jointed by using a conventionally known H-shaped or I-shaped lateral joint member. Is press-fitted so as to fill the gap formed between the and joiner.

In the above description, as the outer wall material, one having a plurality of sawtooth step portions formed in the horizontal direction on the surface as shown in FIG. 2 is used, but it is used in the implementation of the method of the present invention. The outer wall material that can be used is not necessarily limited to such a specific shape, and for example, outer wall materials having various cross-sectional shapes or surface shapes as illustrated in FIGS. 6 (A) to (D) are also applicable. By using the tape-shaped sealing material having a shape capable of filling the gap with the joiner in correspondence with these complicated cross-sectional shapes or surface shapes, connection construction can be performed at the corners of the wall surface or the lateral joints.

<Effects of the Invention> In the present invention, the surface step of the outer wall material when connecting and constructing the outer wall material having a plurality of step portions or grooves extending in the horizontal direction on the surface at an arbitrary location such as a wall corner or a lateral joint. It can be easily installed by using a tape-shaped sealing material with a cross-sectional shape that corresponds to the shape of the groove or groove, and press-fitting this into the gap with the joiner, and the compression restoring force completely fills the gap. By doing so, it is possible to provide a remarkably excellent waterproof effect, and it is possible to greatly improve the durability of the joiner. In the present invention, the joiner that has been conventionally used is utilized as it is, and the troublesome caulking material filling work that has been conventionally required is eliminated.
