Description

[Detailed explanation of the invention] (Industrial application field) The joint between building cladding materials according to this invention is
For example, it is used to join the edges of wall boards called siding materials,
The purpose is to improve the strength of the joint.

(Prior art) For the purpose of decoratively decorating the exterior walls of not only wooden houses but also reinforced concrete buildings and steel-framed concrete buildings, or for insulating the wall portions,
Covering with a facing material (wall board) called siding material is widely practiced.

As shown in Figs. 4 and 5, such a surface material 8 is formed in such a manner that the surface material 8 is arranged in the width direction (Figs. 4 to 5) of the base portion 2 of the long metal plate 1.
5) Both end edges are connected to the metal plate 1
The base portion 2 is folded toward the rear surface side (left side in Figures 4 and 5) to form first and second folded edge portions 3, 4, and a heat insulating material 5 is attached to the inside of the area surrounded on three sides by the base portion 2 and the first and second folded edge portions 3, 4.

Of the first and second bent edges 3 and 4,
The tip of the first bent edge 3 is a thin protrusion 6, and the second bent edge 4 is provided with a plurality of facing materials 8, with the engagement groove 7 into which the protrusion 6 can be freely inserted. ，
8 are combined, so that no gap exists between adjacent facing materials 8, 8.

When covering the exterior wall surface of a building with such facing materials 8, 8, a structure in which adjacent facing materials 8, 8 are combined is called a flat surface as shown in FIG.
One where the facing materials 8, 8 are stretched on the same plane, and the fifth
The siding shown in the diagram is called. Each facing material 8,8
There are some that are strung in steps with their edges overlapped.

These two types of tensioning methods are often chosen to change the appearance of the building or according to the preferences of the lathe owner.

However, in the case of conventional facing materials, special facing materials are prepared for flat surfaces and sidings, and it is not possible to perform siding using facing materials for flat surfaces. It was not possible to do so, and conversely, it was not possible to use a facing material for siding to create a flat surface.

For this reason, the number of types of facing materials to be manufactured has increased, and the time and effort required not only to manufacture them but also to manage them has become tedious.
This increases the cost of lathing the exterior walls of buildings using facing materials.

In order to eliminate these inconveniences, the applicant first devised a facing material that could be used for both flat siding and siding with one type of facing material (application filed in 1983-
No. 043449).

As shown in FIGS. 6 and 7, the mounting material 8 according to this earlier application has both edges in the width direction (up and down direction in FIGS. 6 and 7) of the substrate portion 2 of the strip-shaped metal plate 1 attached to this substrate portion. 2 toward the back side (left side in FIGS. 6 and 7) to form first and second bent edges 3, 4, and the substrate part 2 and both first and second bent edges 3, 4. A heat insulating material 5 is attached to the inside of the part surrounded on three sides by. This facing material 8 is
An engagement groove 10 is formed in a part of the first bent edge 3.
and an engaging protrusion 11 are formed, and an engaging groove 12 is formed in a part of the second bent edge 4.

As shown in FIG.
By engaging the engagement grooves 12 of the upper facing material with the tips of the materials 1 and arranging them, flat tensioning can be achieved.

In addition, in order to perform siding with this facing material and connecting metal fittings, as shown in FIG. If the left end portion 9a is fitted into the engagement groove 10 of the lower facing material 8, each facing material 8,
8 can be sided.

However, although the facing material according to the earlier application constructed and used as described above can be used for flat cladding and siding by using or not using joining metal fittings, there are problems as described below.

That is, when siding these facing materials 8, 8, as shown in FIG. 6, the facing materials 8, 8 are joined together using a joining fitting 9, but in this structure, only the facing material 8 in the middle part is connected. cannot be attached or detached independently.

When covering the wall surface of a house or the like with new covering materials 8, 8, there is no particular problem since the covering materials 8, 8 are pasted in order from the bottom, but if the covering material 8 is located in the middle,
If the cover material 8 is dented by a flying stone or the like and needs to be replaced, the replacement work will be extremely troublesome if only the intermediate covering material 8 cannot be attached or removed.

A design for a connecting portion of the facing material which eliminates such inconveniences is disclosed in Utility Model Application No. 62-055917. As shown in FIG. 8, this invention has first and second bent edges 3,
4, and the upper first folded edge 3 has a
A fitting protrusion 15 is formed in the middle part, and the edge portion located on the outer side in the width direction of the fitting protrusion 15 is used as a mounting plate part 16, and the lower second bent edge 4 is provided with a mounting plate. A fitting groove 1 into which the fitting protrusion 15 can be freely fitted is provided in the receiving plate portion 17 folded inward in the width direction of the material 8.
8.

If the facing materials 8, 8 are to be flat-covered, the 9th
As shown in the figure, when the fitting protrusions 15 and the fitting grooves 18 of the vertically adjacent facing materials 8, 8 are directly fitted to form a siding, a metal plate is used as shown in Fig. 10. The upper end of the joint fitting 19 formed by bending is fitted into the fitting protrusion 15 of the lower facing material 8, and the lower end is fitted into the fitting groove 18 of the upper covering material 8, respectively, to connect the adjacent facing materials 8, 8. combine. In order to elastically maintain the fit between both ends of the coupling fitting 19 and the fitting protrusion 15 and fitting groove 18 of the covering material, small protrusions are formed on each of the above parts for engagement. There is.

Since the upper and lower covering materials 8 and 8 can be elastically engaged and disengaged from each other in the direction perpendicular to the wall surface 14, only the intermediate covering material can be removed without removing the upper covering material 8. It is. That is, it becomes possible to replace only the covering material 8 in the middle part.

(Problem to be solved by the invention) However, when siding is performed using the facing material having the structure according to the earlier application, the upper part of the coupling fitting 19 that engages with the lower facing material and the upper facing material are connected to each other. Since the distance a (Fig. 10) from the lower part to be engaged increases,
The bonding strength between the vertically adjacent facing materials 8, 8 was not sufficient, and there was a risk that the bonded portion would come off during strong winds.

The joint portion between building cladding materials of the present invention is intended to provide a structure of the joint portion between cladding materials that can improve the bonding strength.

The first bent edge 3 includes a thin wall portion 20 that is recessed from the substrate portion 2 side toward the back side to make the heat insulating material 5 thinner, and The fitting protrusion 15 protrudes toward the surface from the bottom, the fitting recess 21 enters the base of the fitting protrusion 15, and extends upward on the extension of the back surface of the facing material 8 (the surface of the heat insulating material 5). A mounting plate portion 16 is formed.

The second bent edge 4 includes, in order from the base plate 2, a receiving plate portion 17 protruding toward the back side, a fitting groove 18 recessed toward the front side, and a groove 1 extending from the edge of the fitting groove 18.
8 and a fitting protrusion 26 that enters into the inner part 8 is formed.

The coupling fitting 19 is made by bending a band-shaped metal plate, has a support plate part 27 at one end that overlaps the mounting plate part 16 of the facing material 8, and has a fitting groove 18 formed in the facing material 8 in the middle part. A fitting protrusion 29 that engages with the fitting protrusion 29 and a fitting protrusion 30 that engages the fitting recess 21 of the facing material are formed.

(Function) In order to siding the two facing materials formed as described above using joining metal fittings, the lower facing material 8

Next, the fitting protrusion 29 of the coupling fitting 19 is fitted into the fitting groove 18 of the second bent edge 4 of the upper facing material 8, and the fitting protrusion 26 of the covering material is engaged with the stepped portion 31. Then, connect the joining fittings and the facing material shown in the table above. Thereby, the upper and lower facing materials are connected via the coupling fittings.

In this connected state, the connecting fitting 19
As shown in the figure, the mating protrusions 15 are arranged in a substantially horizontal direction.
Since it is located along the upper surface of the fitting groove 18, the engagement position between the fitting recess 21 and fitting protrusion 26 of the upper and lower facing materials and the fitting protrusion 30 and step 31 of the coupling fitting is also They are lined up almost horizontally, and the horizontal distance is
This is much smaller than the distance a of the similar engagement position in the previous design shown in FIG. Therefore, the bonding strength between the upper and lower adjacent facing materials is significantly improved.

(Example) Next, the present invention will be explained in more detail by explaining the illustrated embodiment.
