Abstract

PURPOSE:To improve efficiency in execution of work and to improve waterproofness without the need for troublesome caulking processing. CONSTITUTION:A fitting groove 8 is formed at each of butt end faces on both sides of a long, board-like dry wall materials B, and a joiner A with a rainwater drain 1, approximately in dent-like section, provided thereon with both side ends thereof in rectangular plate-like shape bent is inserted into each of the fitting grooves 8 of the dry wall materials B that are placed adjoining each other on the right and the left. As the rainwater drain of the joiner A functions as weathering and ensures waterproofing by letting the rainwater coming into a vertical joint flow toward a groundsill, the vertical joint with high waterproofness can be constructed without the need for troublesome caulking processing. Furthermore, as the joiner A can be fixed with the dry wall materials B installed on the right and the left, any backing material for supporting and fixing the joiner is not necessary for the vertical joint. Thereby, efficiency in execution of work can be improved while materials can be saved.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of vertical joints appearing at a connecting portion of dry wall materials, and more particularly to a vertical joint structure which is improved in waterproofness without caulking.

[0002]

2. Description of the Related Art In general, vertical joints such as tiles, ceramic tiles, extruded hollow building materials, etc. are generally constructed such that the joints are filled with a backup material and caulking material and then stored.

[0003]

However, in order to caulk and store the vertical joints as described above, a backing material and a base material for supporting the caulking material are required on the back surface side of the vertical joints. In addition, when the caulking process is performed without forming the base, hollow caulking occurs, and there is a drawback that the adhesive strength of the caulking material deteriorates and the waterproofness is poor. Further, it takes a lot of time and labor to fill the backup material and the caulking material, and it takes about 1 to 3 days to cure the caulking material until it is completely stable, which is troublesome.

[0004]

In order to eliminate such drawbacks, the present invention forms a single mating groove on both wood mouth surfaces of a long plate-shaped dry wall material so that both side ends of a rectangular plate are formed. Since the joiner, which is bent to form a rain gutter with a substantially concave cross-section, is inserted into the mating grooves of the dry wall materials that are adjacent to the left and right to form a vertical joint structure,
Since the rainwater ditch of the joiner functions as a rain catcher and the rainwater that has entered the vertical joints flows down toward the base to waterproof it, a troublesome caulking process is not required, and the joiner is fixed on the left and right dry walls. Since it is made of wood, a vertical joint structure which does not require a base material for fixing and supporting separately in the vertical joint is proposed.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A typical embodiment of the vertical joint structure according to the present invention will be described in detail below with reference to the drawings. FIG. 1 is an explanatory view showing the above structure, which comprises a joiner A and a dry wall material B.

It is formed by extrusion molding using RP resin or the like.

As shown in FIGS. 4 (a) and 4 (b), the hard wall material B is made of porcelain stone, feldspar, kaolinite, halloysite, metahalloysite, kibushi clay, frog eye clay, and Shigaraki. Clay material made by crushing clay and kneading with water, or cement-based, calcium carbonate-based, calcium silicate-based, wood chip cement-based, magnesium carbonate-based material, or glass fiber, whiskers, aramid fiber, steel fiber , Carbon fiber, various mineral fibers, various aggregates, etc. mixed by extrusion molding, press molding, injection molding, papermaking method, etc., or various fibers woven in a cross shape, three-dimensional shape, cement , A panel-shaped product impregnated with clay or the like, which is steam-cured or fired.

The shape thereof is a long plate-like shape, and has male and female portions 5 and 6 having a conical shape on both side edges of the surface of the decorative surface 4 in the width direction. A pair of substantially concave fitting grooves 8 parallel to the decorative surface 4 is formed on the mouth end surface 7 on the side walls at both ends in the width direction. Further, in FIG. 4B, a plurality of hollow holes 9 are formed inside in parallel with the longitudinal direction in order to shorten the insertion time from the raw material and save the raw material.

As shown in FIG. 1, the fitting groove 8 fits both ends of the joiner A to integrate the hard wall material B and the joiner A. Further, the bottom side 2 is in close contact with the female part 6 of the hard wall material B to improve drainage of rainwater flowing down through the rainwater ditch 1 at the joint part, and the upper side 3 is the male part 5 of the hard wall material B. To prevent rainwater from entering the inside of the joint through the back side of the joiner A. Also,
When the length of the fitting groove 8 is L ₁ in FIG. 4 and the length of the rainwater groove 1 is L ₂ in FIG. 3, there is a relationship of L ₁ = L ₂ .

Next, a construction example will be described. Joiner A as shown in FIG. 3 and hard wall material B as shown in FIG.
It is assumed that a wall body as shown in FIG. 2 is constructed by using and. First, one of the left and right hard wall materials B is fixed to the wall base by using a fixture, a fixture or the like. Next, the side end of the joiner A is fitted into the fitting groove 8. Then, the other side wall of the joiner A is inserted into the fitting groove of the adjacent hard wall material B, and is aligned in a horizontal direction. The wall is formed by sequentially performing this work from the base direction toward the eaves direction.
