Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a case in which natural stone such as granite is applied as an exterior wall panel to an outer wall of a house or the like, and more particularly to a cross joint structure of the outer wall suitable for renovation.

[0002]

2. Description of the Related Art In general, there is a siding material as a typical example of an exterior wall panel suitable for renovation. This siding material is filled with a heat insulating material such as polyurethane foam on an inner surface of a base plate. It is constructed by a so-called blow-up method so that the base plate is exposed as an outer wall surface as it is. Because the outer wall, that is, the base plate, is mostly made of embossed colored steel plate,
There is a limit to its processing, and it is inevitable that it has poor solid feeling and luxury, and its surface has become dirty and poor in durability over several years of use.

[0003] Therefore, in order to give a sense of dignity and durability,
Although the outer wall surface is made to be a tile specification, for example, as shown in Japanese Utility Model Laid-Open No. 59-147832, a support having an engagement concave portion on the back surface side of the tile and an engagement convex portion on the frame side is provided. Is fixed, and the engaging concave portion of the tile is assembled to the engaging convex portion of the support so as to simplify the tiling work.

[0004] However, in the tile specification, the allocation of the tile material is fine, so that if a separate joint material is to be provided, the number of parts increases, and it is difficult to install the joint material in a straight line, and it is difficult to work. Is bad.

[0005] On the other hand, in the case of a pottery such as a tile material, the above-mentioned engaging concave portion can be molded at the manufacturing stage. However, natural stone materials such as granite are cut into stones and manufactured like a tile material. Therefore, it was practically impossible to form the engaging recess directly on the back surface side.

Therefore, when natural stone such as granite is used as an exterior wall panel, the size, weight, allocation, etc. of one piece are completely different from those of the tile specification. I couldn't do that. Therefore, as a construction method for natural stone, "dry stone construction method" (design and construction guidelines for dry stone construction method for exterior walls / figure explanation 1)
997) has been proposed as a design and construction guideline, but there is a problem that the work is complicated and time-consuming. There has been a demand for a construction means that is optimal for natural stone materials, has excellent workability, and can shorten the construction period.

[0007]

SUMMARY OF THE INVENTION The present invention has been made in order to eliminate the above-mentioned problems, and uses an exterior wall panel made of natural stone or the like which is relatively heavy and has a large surface area. Despite this, the joining work between adjacent side-girder ground materials becomes the work of attaching the side-girder ground material to the frame as it is, and the construction is completed immediately, so workability is excellent and the construction process can be simplified. In addition, not only can the construction time be shortened when the construction wall is wide, it can contribute to shortening the construction period. be able to.

In addition, even if the material is peeled off from the main body due to an earthquake or the like, since the horizontal joint material is also used as a support member of the wall panel, it can be reliably prevented from falling off, and there is a slight dimensional error in the vertical width. Even in the case, the side grove is also used to cover the foreground of the wall panel, so that the error can be absorbed and a clean appearance can be achieved, and the side grove can be drained even when rainwater enters. An object of the present invention is to provide a lateral joint structure of an outer wall that functions as a road and that can reliably drain to the vertical joint side and prevent entry.

[0009]

In order to solve the above-mentioned problems, a lateral joint structure of an outer wall according to the present invention comprises a plurality of horizontal frames arranged at predetermined intervals in a vertical direction with respect to a frame constituting the outer wall. In the outer wall construction structure in which a plurality of exterior wall panels are constructed so as to form a horizontal joint at the portion with respect to the horizontal frame, the joint material covers the edge of the wall panel from the surface side. A fastening member which is constituted by a covering member and a locking member provided on the covering member, and which is attached to the locking member and locked to the horizontal frame when the joint material is mounted on the horizontal frame. And the fixing member is also used as a connecting member for connecting adjacent joint members.

Sliding and inserting the insertion groove 601b of the adjacent horizontal joint base material 6 into the insertion piece 121 of the fastening member 12 enables connection and functions as a connecting member. The joining work of the base materials 6 becomes the work of attaching the horizontal-grain base materials 6 to the horizontal frame 5 as it is, so that the construction can be completed immediately, the workability is excellent, and the construction process can be simplified. The wider the wall, the shorter the construction period can be.

In short, the horizontal frame 5 and the horizontal joint base material 6
And the fastening member 12, the side joint base material 6 is fitted on the horizontal frame 5, and the fastening member 1 is attached to the locking member 603 of the side joint base member 6.
After the second joint 2 is attached and attached, it is configured such that the adjacent horizontal joint base material 6 can be installed in an order of attachment by fitting to the horizontal frame 5 and connection to the fastening member 12. Therefore, as compared with the mounting structure of the horizontal joint base material 6 provided with the locking member 602 and the horizontal frame 5, even after one end of the construction, the above-described mounting configuration can be sequentially performed in reverse. 5, there is an advantage that the re-installation can be easily performed without damaging the members such as the side-grain base material 6, the fastening member 12, and the like, so that even those who do not have skilled construction skills can carry out the construction with ease.

Further, the fastening member 12 is provided with a setting block 122 which resiliently contacts the horizontal frame 5 so that the fastening member 12 can be attached to the preceding horizontal joint base material 6 alone. Alternatively, when the insertion piece 121 is inserted into the insertion groove 601b of the adjacent horizontal joint base material 6 with respect to the fastening member 12 attached to the preceding horizontal joint base material 6, the proper posture is maintained. A slide insertion operation such as positioning can be easily performed.

The horizontal joint material 6 is formed by covering the horizontal frame 5 with the covering member 601 and the edge of the wall panel 1 with a predetermined gap 8 from the surface thereof.
Is installed so as to form a protruding joint, so that even for a relatively large exterior wall panel 1 such as a natural stone material, it is not necessary for a craftsman to perform a complicated construction work with a plastering finish, and the wall surface is not required. It can be easily assembled simply by assembling it to each of the frames arranged. Therefore, not only the on-site work is significantly simplified, but also the finish of the panel assembly does not vary due to the difference in the skill of the worker, and the stone outer wall full of a heavy feeling can be efficiently and inexpensively constructed. become.

Further, even in the event that the adhesive with the skeleton 2 is peeled off due to an earthquake or the like, since the cross grain base material 6 functions as a support member for the wall panel 1, it can be reliably prevented from falling off.
Further, even when there is a slight dimensional error in the vertical width, the horizontal joint base material 6 becomes a small edge of the wall panel 1, and the error can be absorbed to achieve a neat appearance.

In this case, the horizontal joint base material 6 is assembled into the horizontal frame 5. In this case, the edge of the wall panel 1 and the covering member 601 have a gap corresponding to the thickness of the support piece 604. Since the gap 8 is formed as a discharge path for discharging rainwater or the like, there is an advantage that drainage from the vertical joint portion 3 is performed and waterproofing can be surely performed.

Further, the interposition of the support piece 604 allows the panel to be supported without rattling, and
The panel can be permanently prevented from falling off.

The edge of the wall panel 1 and the covering member 60
Since the sealing material (sealant) 7 is interposed in the gap 8 formed by the first member 1, the engagement piece 503 provided on the horizontal frame 5 is locked by the adhesion force of the sealant (sealant) 7. Locking piece 60 provided on member 602
1a can be more firmly fitted, and reliable waterproofing can be performed.

In this embodiment, the case where the existing wall surface is reformed has been described as an example. However, the present invention is not limited to this case, and the present invention can be applied to a new wall surface. Furthermore, the present invention is not limited to these, and can be applied to remodeling of an inner wall surface and a newly installed inner wall surface.

Is attached via a fastening member 12 that is attached to the horizontal frame 5 and is locked to the horizontal frame 5. The fastening member 12 is also used as a connecting member that connects adjacent joint members, so that the adjacent The joining operation of the base materials 6 becomes the work of attaching the side-grained base materials to the frame as it is, so that the construction can be completed immediately, the workability is excellent, the construction process can be simplified, and the construction wall is wide. It can contribute to shortening of the construction period as much as possible, and furthermore, it is possible to easily perform the construction again even after the construction is once completed, and even those who do not have skilled construction skills can carry out the construction with confidence.

Further, according to the present invention, the exterior wall panel 1 is mounted on the horizontal frame 5 provided on the predetermined frame 2,
Further, by merely fitting the side joint material 6, the projecting side joint part 4 is formed, and the gap (drainage channel) 8 is formed by the covering member 601 covering the upper and lower edges of the wall panel 1. Therefore, even if the wall panel 1 made of natural stone or the like having a relatively large weight and a large surface area is used, or if the wall panel 1 is peeled off from the skeleton due to an earthquake or the like, the side-grained ground material 6 is kept in place. Since the support member is also used as the support member, not only can it be reliably prevented from dropping off, but even if there is some dimensional error in the vertical width, the side-grain base material 6 is also used for concealing the fore-edge of the wall panel 1. By absorbing the error, it is possible to finish the appearance neatly, and, furthermore, the cross-groove base material 6 functions as a drainage channel even for rainwater or the like,
Drainage can be reliably prevented to the vertical joint side to prevent entry.
