Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a joint sealing material that is held between end faces of exterior wall materials when the exterior walls are formed by arranging rectangular exterior wall materials in the vertical and horizontal directions.

Generally, when rectangular exterior wall materials are arranged vertically and horizontally to form an exterior wall, the butt joints of the exterior wall materials are filled with a waterproof paste joint material. Alternatively, since a large amount of such joint material is used, a back-up material thinner than the thickness of the outer wall is provided in advance, and the paste-like joint material is embedded on top of this.

Various types of wet sealants are used as the above-mentioned joint materials, but all of them require skilled techniques such as primer treatment, spatula pressing, leveling, etc., so the work of filling the joints must be left to specialized craftsmen. This is one of the reasons why construction costs are high. Furthermore, the filling of joints affects the beauty and ugliness of the outer wall appearance, and the finished state is uncertain, and in some cases, there are disadvantages such as leakage accidents after construction.

In view of the above-mentioned circumstances, the present invention has been developed to easily achieve watertightness by sandwiching rectangular exterior wall materials between the end faces of the exterior wall materials when they are arranged vertically and horizontally to form an exterior wall. The purpose of this product is to provide a sealing material for joints forming an exterior wall with an excellent appearance. A long cushion part having a predetermined thickness and a width smaller than the thickness of the outer wall material, which is attached along each butted end surface and closer to the outer surface side of the outer wall material, and to the end surface of the outer wall material in the cushion part. The bent plate part is attached to the side opposite to the contact surface of the board, has a width approximately corresponding to the thickness of the external wall material, is waveform in the thickness direction of the external wall material, and has the wavy end facing toward the external wall material. a cushionable engagement member;
a filler sandwiched between the bending plate parts of two opposing cushioning engagement members, and having a cross-sectional shape having a waveform on both sides, at least both sides of the inner surface of the outer wall closely fitting into the waveform part of the bending plate part; , a plate portion that closes the joint from the inner surface side of the outer wall and comes into contact with the inner surface of the outer wall; and attached to this plate portion, two long plates corresponding to the width of the joint protrude in parallel, the tips of which are bent to face each other. The present invention also provides a joint sealing material comprising a locking member comprising a locking portion having a slit for sandwiching the inner surface side of the outer wall of the bent plate member.

The present invention will be explained below with reference to the drawings.

Figures 1 to 5 a and b show an embodiment of the joint sealing material according to the present invention. It is a partially enlarged view of a part. Reference numeral 1 in the figure is an extruded concrete rectangular exterior wall material.
The longitudinal edges have a solid structure. The outer wall 4 is constructed by arranging these horizontally and vertically and attaching them to pillars 2 and studs 3. This exterior wall material 1,1
A joint sealing material A according to the present invention is sandwiched between the joint 5 at the abutting portion of the end surfaces 5a and 5a.

This joint sealing material A is composed of a cushioning engagement member 8 consisting of cushion parts 6, 6 and bending plate parts 7, 7 provided oppositely, a filling member 9, and a locking member 10. ing.

The cushioning engaging member 8 is constructed as shown in a cross-sectional view in FIG. That is, the cushion parts 6, 6 are along the outer wall material end surfaces 5a, 5a,
and are respectively arranged closer to the outer wall outer surface 4a side,
Its width is smaller than the thickness of the outer wall material, and its thickness is appropriately selected depending on the width of the joint 5, and an arc-shaped groove is provided on the surface 6a on the outer wall outer surface 4a side. Examples of materials for forming the cushion portion 6 include closed-cell foamed polyvinyl chloride, polyethylene,
Alternatively, materials with excellent elasticity such as chloroprene rubber, soft rubber, and rubber-like plastic without water absorption or water permeability may be used. Further, the bent plate parts 7, 7 have a width approximately equal to the thickness of the outer wall material, are formed in a wave shape in the thickness direction, the ends thereof face the outer wall material outer surface 4a, and the outer wall material inner surface 4b side: Plate-shaped flat plate portions 7b, 7
b is formed, and the flat plate portions 7b, 7b form a pair and open on both sides to form a V-shape. The bent plate portions 7, 7 are made by extruding plastic, bending a plastic plate and a metal plate, or the like. These bent plate parts 7, 7 are adhesively fixed to the opposing surfaces of the cushion parts 6, 6 at the corrugations 7a, 7a on the outer surface side of the outer wall material using an adhesive 11 or the like in a line-symmetrical manner, and the cushioning engagement members 8, 8 is formed.

In addition, as shown in the cross-sectional view in FIG. 4a, the filling member 9 has corrugated concave and convex portions 9a, 9a on both side surfaces close to the outer wall outer surface 4a, which are shaped to fit tightly into the curved plate corrugations 7a, 7a. is formed, and a plate-shaped portion 9b located between the flat plate portions 7b, 7b is formed on the side closer to the outer wall inner surface 4b. The height of the filling member 9 is approximately the same as the thickness of the outer wall material, and is made by extruding synthetic resin or by bending a metal plate or the like as shown in FIG. 4b.

Further, as shown in the cross-sectional view in FIG. In order to determine the interval width, the end faces 5a,
A locking portion 10b is provided which protrudes along the curve 5a and has a slit 10c formed in the oppositely bent ends thereof, and is adapted to clamp the flat plate portions of the bent plate portions 7, 7 from both sides. This locking member 10 is
The plate part 10 is formed by extrusion molding of synthetic resin, or by a metal plate, synthetic resin plate, etc. as shown in FIG. 5b.
a. The locking portion 10b may be formed separately and these may be integrated by welding or the like, but they may also be integrally formed. Alternatively, the plate portion 10a may be made equal to the joint spacing and not laid on the inner surface of the outer wall material.

Next, how to use each member configured as described above will be explained.

First, when forming the outer wall 4 by arranging the outer wall material 1 in the horizontal direction and the longitudinal direction, the locking portion 10b of the locking member 10 is held between the opposing end surfaces 5a, 5a of the outer wall material, and the pillar 2 , installed on stud 3. Next, the cushion engaging member 8 is disposed within the joint 5 by placing the bent plate portions 7, 7 facing each other, and inserting the flat plate portions 7b, 7b into the clamped locking member and slit 10c. Next, the filling member 9 is pushed between the bending plate parts 7, 7 by utilizing the elasticity of the cushion parts 6, 6. By this operation, the corrugated portions 7a, 7a and the corrugated concavo-convex portions 9a, 9a are fitted together, and the joint sealing material A is set between the end faces of the outer wall material, as shown in the cross-sectional view of FIG.

In the above operation, since the widths of the bent plate parts 7, 7 and the filling member 9 are approximately equal to the thickness of the outer wall, the flat plate parts 7b, 7b are inserted into the slit 10c, and the filling member 9 is inserted into the bent plate parts 7, 7 and the filling member 9. 7, the cushion parts 6, 6 are pressed and fixed to the side closer to the outer surface 4a of the opposing surfaces 5a, 5a as shown in FIGS. 7a, b, c, and the joint sealing member A is easily removed. It is formed in a fixed position and shape. Further, the arc-shaped surface 6a of the cushion portion 6 becomes flat due to the above-mentioned pressing.

Note that the outer shape of the joint may be changed by making the surface 9c of the filling member 9 concave as shown by the two-dot chain line, or by slightly reducing the width of the bending plate portion 7 and the locking member 10. A step can be provided on the outer surface 4a.

Although it is not absolutely necessary for the arcuate surface 6a to have the concave surface 9c, it is effective in improving the appearance of the joint. As described above, when the joint sealing member A is disposed vertically, even if rainwater etc. enters through the abutment part 12 between the bending plate part 7 and the filling member 9, the vertical cavity Rainwater that has entered at 13 flows downward, and does not enter the outer wall outer surface 4b.

However, if the joints are in the horizontal direction, the hollow portion 13 will be horizontal and the rainwater that has entered will not be discharged. In this case, the intrusion of rainwater can be prevented by applying grease to the corrugated uneven portions 9a of the filling member 9 and pushing them in.

Therefore, even when forming an external wall by arranging rectangular external wall materials 14 without engaging parts, such as a real structure, vertically and horizontally, as shown in FIG. Sealing can be performed using the joint sealing member A according to the above.

Further, as shown in FIG. 9, when the joint sealing member A according to the present invention is used in an extrusion-molded hollow outer wall material 15 provided with a large number of parallel holes 15a in order to reduce weight and improve heat retention. In this case, the joint sealing member A may be attached in the same manner, taking care not to completely block the hole 15a with the cushion portion 6. This prevents the hole from changing due to changes in temperature, etc.
There is no pressurization or depressurization inside 5a, and therefore no load fluctuations are caused to the sealing material, so it is possible to completely prevent rainwater from entering through the joints.

As described above, when forming an exterior wall, the joint sealing member according to the present invention is firmly clamped by sequentially combining each member between the end faces of the exterior wall material, and its placement position is determined by itself. Since it is set in a fixed position, no skill is required for installation, and an exterior wall having excellent-looking joints that prevent rainwater from entering easily and regularly is formed.
