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 material or similar wall materials, the joints of each wall material are butted, and a joiner that sandwiches both wall materials from the front and back is used to prevent rain. It had been put away.

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

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

Further, there were drawbacks such as unevenness formed on the surface of the joint, resulting in an unsightly finish as a wall surface.

The present invention relates to an improved wall structure that eliminates the above-mentioned drawbacks, provides a good wall surface finish, and makes it possible to prevent rainwater from entering.

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 are carved in both longitudinal end faces 16 of the wall material 1 over the entire length in the width direction of the wall material.

Thus, in the main joint part 13, in order from the outer surface of the wall, there is a step 13a that faces upwardly, and above the step 13a there is a sloped surface 13b that is an overlapping surface in the thickness direction. 13C and the upward shoulder portion 13d are continuous.

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 facing surface 14a, a converging reversely facing inclined surface 14b which is an overlapping surface in the thickness direction, and a downward facing surface 14d of the downward grooved portion 14C1.

The upper and lower joint portions 13 and 14 have a convergent shape as a whole.

A joiner 2 made of an elastic material is fitted into the joiner groove 15.

That is, as shown in FIGS. 4 and 5, the joiner 2 has a longitudinally elongated strip shape, and includes 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 installed adjacent to each other in the length direction, the width is suitable for the joiner groove formed by both wall materials, and the folded height H of the folded 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.

Next, the mounting state will be explained.

The wall material 1 is stretched horizontally and vertically with the respective end faces aligned, but in order to attach it to the studs 3 or the frame, it is necessary to connect the lowermost first stage in the length direction and extend it from the bottom to the top of the rear wall. Work is progressing towards.

That is, first, the joiner 2 is fitted into both joiner grooves 15, 15 on the abutting end surfaces of the respective wall materials on which the first lower stage is formed, and the joiners are joined together.

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 such that the downward facing surface 14d of the second stage is in contact with the upward shoulder 13d of the first stage. place

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

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

The joiner 2 is provided with a folding part 2b, and the folding height H in the free state (Fig. 6) is determined by the difficulty h of the joiner groove.
Since the joiner 2 is formed larger, when the joiner 2 is inserted into the joiner groove 15, a tight fit is achieved by the elastic repulsive force of the folded portion 2b.

This strengthens the combination of the left and right wall materials, and the joiner groove itself becomes a sealed drainage channel, helping to prevent rainwater from seeping into the inside of the wall.

As another example, as shown in FIG. 5, a caulking agent is applied to the inner part of the folded part 2b of the joiner 2 and the front side of the central part of the main body 2a, which corresponds to the left and right butt joints in the length direction of the wall material. If the adhesive 4 is applied in advance, the prevention of rainwater seepage will be even stronger.

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

In addition, a joiner groove is provided on the end face of the central part of the joint part of the wall material, and a joiner that runs along the vertical direction is fitted into the groove, and the joiner overlaps at the upper and lower ends, so rainwater flows down along the joiner. However, it does not seep into the inside of the wall.

Furthermore, since the joiner has elastic deformation fitting parts on the left and right ends of the joiner into the wall material joiner groove, it has many effects such as more completely preventing rainwater from seeping in and strengthening the joint between the wall materials.

In addition, since this elastic deformation fitting part consists of folded parts that are symmetrically bent in a U-shape so as to approach each other from the left and right ends of the vertical strip plate on the wall surface side, the U-shaped folded parts can be used as joiners. It can be fitted simply by pushing it into the groove, making the work simple and quick.
