Description

[Detailed Description of the Invention] The present invention relates to a wall structure in which extruded wall materials are joined by a specially shaped joiner.

Conventionally, when constructing a wall using rectangular asbestos cement boards or similar wall materials, the joints of each wall material were butted, and a joiner was used to sandwich both wall materials from the front and back. It had been rained out.

However, rainwater enters through the gap between the joiner and the wall material.

This caused near-fatal damage to the wall, but it was difficult to completely block rainwater from entering.

In addition, when installing wall materials, it is difficult to correctly match the height of each wall material that is continuous in the horizontal direction, and it is necessary to measure the height each time when installing the wall materials, which is a time-consuming and highly skilled task. Met.

Moreover, the finished wall surface had unevenness formed on the surface of the butt joint, and the finish was unsightly in terms of appearance.

The present invention relates to an improved wall structure that eliminates the above-mentioned drawbacks, has a good finish on the wall surface, completely prevents rainwater from entering, and allows the height of the wall material to be easily set at a constant level.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

In FIGS. 1 to 3, the wall material 1 is made of asbestos cement extrusion material in the shape of a horizontally long flat plate, and a plurality of cavities 11 are provided which are passed through the wall material 1 in parallel at equal intervals along the length direction of the wall material 1. It will be done.

The cavity 11 is partitioned by a partition strip 12 along the length.

Further, the wall material 1 is formed with a main joint portion 13 and a lower joint portion 14, and joiner grooves 15 extending along the direction of the wall material on both lengthwise end faces 16 of the end faces are formed with iron film.

Thus, the main joint portion 13 is formed into a joint shape and is provided with an overlapping surface facing forward in the thickness direction, and the lower joint portion 14 is also formed into a joint shape and provided with a overlapping surface facing backward in the thickness direction.

That is, in the main joint part 13, in order from the outer surface of the wall, an upwardly inclined step 13a is formed, and above the step 13a, an upwardly inclined surface 13b, which is an overlapping surface, is connected, and furthermore, an upwardly protruding ridge 13C and an upwardly facing shoulder 13d are connected. .

These are formed continuously in the length direction of the wall material 1.

On the other hand, the lower joint portion 14 is composed of, in order from the front surface, a downward inclined surface 14b which is a downward facing surface 14a and an overlapping surface, a downward grooved portion 14C1 and a downward facing surface 14d.

A waterproof joiner 2 made of an elastic material is provided in the joiner groove 15.
is fitted.

That is, the waterproof joiner 2 has a vertically long strip shape as shown in the fourth and fifth figures, and has a main body 2a bent to match the shape of the main joint 13, and a main body 2a that extends from the left and right ends of the main body 2a on the same side with respect to the main body. The folded portions 2b are symmetrically bent in a U-shape so as to approach each other.

When the two wall materials 1 are attached adjacent to each other in the length direction, the width is suitable for the joiner groove formed by both wall materials, and the folding height H of the folding portion 2b is such that It is set to a value that allows it to be elastically deformed to a height h and fit into the joiner groove 15.

(Figure 6). In the embodiment, the joiner groove 15 is formed by cutting out the partition strip 12, but it may also be formed in the thick part in front of the cavity 11.

Further, a positioning joiner 3 is provided inside the waterproof joiner 2 at a position where the longitudinal end faces 16 of the wall material 1 are butted and joined along the studs 4.

As shown in FIG. 7, the positioning joiner 3 includes a vertically long strip-like main body 3a and bent portions 3 that are symmetrically bent from both left and right ends of the main body 3a so as to approach each other on the same side of the main body.
It consists of b.

Further, on the surface on the side where the bent portion is formed, parallel ruled lines 3C are engraved at equal intervals above and below.

A plurality of attachment holes 3d are drilled in the center portion of the positioning joiner 3 in the left-right direction, and the positioning joiner 3 is attached to the studs with nails or screws through the holes.

Next, the installation state will be explained.

First, the positioning joiner 3 is sealed to the stud 4 at a position corresponding to the abutting portion of the longitudinal end surface of the wall material, with the surface on which the ruled lines 3C are engraved facing the outside.

In this case, the mounting height of each positioning joiner 3 is adjusted so that the respective ruled lines 3C are at the same height.

The wall material 1 is stretched in the left, right, top and bottom directions with respective edge metals aligned.

To attach to the studs 4 or to the rim, the lowermost first stage is assembled and tensioned in the length direction, and then the tensioning work is carried out from the bottom of the wall upwards. Construction is performed while aligning the left and right heights of the end faces with the ruled lines 3C of the same height of the positioning joiner 3.

In the above combination, first, both joiner grooves 15.1 of the abutting end surfaces of the respective wall materials forming the lower first stage are
Insert waterproof joiner 2 into 5 and join.

Subsequently, the second stage is assembled in the same manner as described above, and stretched above the first stage with its left and right end surfaces 16 aligned with the left and right end faces of the first stage on the same vertical plane.

At this time, the upward convex strip 13C of the first stage fits into the downward concave strip of the second stage, and the second stage is placed on the upward shoulder 13d of the first stage.
Place it so that the downward facing surfaces 14d of the steps are in contact with each other.

Therefore, the downward facing inclined surface 14b of the second stage is in contact with the upward facing inclined surface 13b of the first stage, and the second stage is overlapped at the front surface in the wall thickness direction of the upper part of the first stage. The waterproof joiner 2 will also be duplicated.

Therefore, even if rainwater flows down through the upper waterproof joiner, it will be stopped by the lower waterproof joiner, and the rainwater will not seep into the interior through the joints of the wall materials.

The waterproof joiner 2 is provided with a folding part 2a, and the folding height H (Fig. 6) in the free state is larger than the thickness h of the joiner groove. 15, the elastic repulsive force of the folded portion 2b ensures a tight fit.

This strengthens the combination of the left and right wall materials, and the joiner groove itself becomes a sealed drainage channel, which further helps prevent rainwater from seeping into the inner wall.

Since each wall material 1 is stretched while its height is adjusted by a positioning joiner 3, the height in the left and right direction is regulated.

The positioning joiner 3 also serves as a barrier against moisture that should seep past the waterproof joiner 2.

In addition, when a window is formed on a part of the wall surface and the wall material needs to be cut to match the edge, it is useful as a measuring tape.You can read the scale and process the wall material, or adjust the wall height. It is also useful for calculating.

Furthermore, the ruled line 3C can be effectively used to cut the joiner 3 itself to a constant length along the line, or to make the overlapping margin of the joiners constant.

FIG. 8 shows another embodiment of a positioning joiner in which a protrusion 5e is provided along the longitudinal direction in the center, and the joiner 5 inserts the protrusion 5e into the abutting portion of the adjacent wall material 1 as shown in FIG. Attach it like that.

Then, a caulking material 6 is filled into the external gap portion.

If the height of the protrusion 5e is matched with the height in the wall thickness direction of the cavity 11 and the cavity 11 is covered, it is useful to block the intrusion of rainwater even when the waterproof joiner 2 is omitted.

As described above, according to the present invention, the abutting portions of the wall structure are joined in an extremely stylish manner, increasing the aesthetic element of the wall surface.

In addition, since the wall material has polymerized surfaces of the upper liquid joint part and the lower joint part facing each other in the direction of the weight of the wall, rainwater does not enter the inside of the wall.

Furthermore, since a ruled line positioning joiner is attached to the inside of the horizontal butt joint portion of each wall material, it not only makes the height of the wall material constant in the left and right direction, but also has many utility values as a measure.
