Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to a dry jointer for sealing a joint formed by providing a gap between adjacent outer wall materials and a dry joint structure for the outer wall.

[0002]

[Prior art]

 In recent years, the use of inorganic or metallic outer wall materials for constructing outer walls has been increasing. Dry joint structures are used to waterproof these joints.

In the joint structure, a substrate member formed by a substrate having a projection protruding from a skeleton and a locking recess provided with a locking portion at the end of the substrate is fixed to the skeleton, and the surface of the substrate is fixed. The outer wall material is disposed on the outer wall material, and the joint portion provided between the outer wall materials has an engaging portion on the bottom portion for engaging with the locking portion of the locking recess, and the joint is sealed on the upper portion. Is formed by fitting a gasket material formed with a seal lip piece formed for this purpose. Then, a flowing channel is formed between the back surface of the outer wall material and the substrate of the substrate member by the projecting portion protruding from the substrate, and water that cannot be waterproofed by the seal lip piece is secondarily stopped by the flowing channel. Water.

[0004]

[Problems to be solved by the invention]

 However, in the dry joint structure as described above, the water that could not be completely stopped by the seal lip pieces formed on the gasket material reaches the substrate, and secondary water is stopped by the flowing water channel. However, there is a high possibility that the outer wall material will freeze and thaw, and there is a problem that the capillarity cannot be prevented because such projections are very small.

The present invention has been made in view of the above circumstances, and has as its object to provide a dry jointer and an outer wall dry joint structure that provide a sufficient water stopping effect.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, a dry jointer according to the invention of claim 1 is provided with a substrate member comprising an engaging concave portion which is provided upright at the center of the substrate and has an engaging portion at its tip. And a joint portion formed between outer wall members made of a gasket material, having an engagement portion at the bottom portion to be fitted and fixed to the locking portion, and having seal lip pieces protruding left and right on the upper portion thereof. It is characterized by being provided with a concave groove which is sealed and is continuous in the longitudinal direction outside the locking concave portion provided upright on the substrate, and a contact portion which comes into contact with the end surface of the outer wall material. .

In the dry wall joint structure according to the present invention, a gap is provided between adjacent outer wall members to form a joint portion, and the substrate member is fixed to a skeleton to seal the joint portion. A gasket material is fitted on the outer wall material, and the outer wall material is abutted on a locking recess having a concave groove on the outside and an abutting portion with which the end surface of the outer wall material abuts, and is erected in the center of the substrate member; It is characterized in that a flow channel is formed between the locking concave portion and the outer wall material by the concave groove of the locking concave portion.

【Example】

 Hereinafter, an embodiment of the dry jointer of the present invention and an outer wall dry joint structure using the same will be described with reference to the drawings. First, as shown in FIG. 1 (a), a dry joint joiner 1 of the present invention comprises a base member 2 made of an extruded product made of a synthetic resin or an aluminum material and an extruded product made of a soft synthetic resin such as rubber. And a gasket material 3.

The board member 2 is composed of a flat board 4 and a pair of locking recesses 5 erected in parallel with the center of the board portion 4. A locking portion 6 is provided on the other side, and a contact portion 7 is further provided on the outside, and the intermediate portion is bent inward to form a concave groove 8 on the outside. The gasket material 3 is inserted into a locking concave portion 5 erected on the substrate member 2 and has an engaging portion 9 at the bottom for fitting and fixing to the locking portion 6. And two upper and lower seal lip pieces 10 projecting therefrom.

The shape of the locking concave portion 5 of the substrate member 2 is such that the contact portion 7 is provided near the substrate 4 as shown in FIG. 1B, and further as shown in FIG. The stepped portion is stepped inward from the surface of the contact portion 7 to form a concave groove 8, and as shown in FIG. There is one in which the contact portion 7 is provided near the substrate 4.

Next, FIG. 2 shows an outer wall joint structure using the dry jointer 1 shown in FIG. In FIG. 2, first, the substrate member 4 of the dry jointer 1 is fixed to the frame 11, and the adjacent outer wall members 12, 12 are brought into contact with the contact portions 7 of the locking recesses 5 erected on the substrate member 4. And arrange them. At this time, a gap formed between the adjacent outer wall members 12 is defined as a joint portion 13. Next, in order to seal the joint portion 13, the gasket material 3 is inserted into the joint portion 13, and the engaging portion 9 of the gasket material 2 is fitted into the locking concave portion 5 of the substrate member 4. Since the projection width of the seal lip piece 10 of the gasket material 3 is wider than the width of the joint part 13, the seal lip piece 10 is pressed against the end face 14 of the outer wall material 12 to seal the joint part 13. . With this configuration, the water channels 15, 15 are formed between the locking recess 5 and the end surfaces 14, 14 of the outer wall members 12, by the concave grooves 8 of the locking recess 5.

With the above-described configuration, water cannot be completely stopped by the seal lip pieces 10, and water that has entered the interior can be secondarily stopped by the flowing water passages 15.

[0013]

[Effect of the invention]

 As described above, according to the dry jointer of the present invention and the outer wall dry joint structure using the same, the following effects can be obtained. A contact portion and a concave groove are formed in the locking concave portion of the base member of the dry jointer, and the outer wall material is disposed with the end surface of the outer wall material in contact with the contact portion, so that the outer wall material and the locking concave portion are formed. A space can be formed between them, and this space can be used as a running channel.

[0014] In this joint structure, the seal lip piece protruding from the gasket material of the dry jointer and being pressed against the end face of the outer wall material stops water. If water intrudes into the interior without being able to keep up, the secondary water is stopped by the flowing water channel, and the water can be reliably drained.
