2. Description of the Related Art Cement-based building materials, which are usually used as a base material for walls of buildings, are covered with a surface material, for example, a decorative member called a decorative board. Are used as composite building materials by providing dovetails to each other and fitting the dovetails to each other. This composite building material has been widely used in recent years because it is securely attached and safe. . Conventionally, in such composite building materials,
After the surface material is hooked in the concave portion of the base material, a fixing metal fitting is necessary for fixing these in order to prevent the surface material from slipping to the opposite side.

Conventionally, the concave and convex portion when fitting the surface material and the base material is the cement board 1 in the one shown in FIG.
In the recess 5 having the dovetail groove, one side wall is in the shape of the dovetail groove 9 and the other side wall is vertical 13. Further, in the convex portion 6 of the decorative plate 2 which is the surface material, the side wall engaging with the dovetail groove 9 has the shape of the dovetail 6, and the other side wall is vertical 14. After fitting the convex portion 6 of the decorative plate 2 as the surface material into the concave portion 5 having the dovetail groove of the cement plate 1 as described above, the end portion of the decorative plate 2 is fitted with the metal fitting 3
It is fixed by stopping with a tapping screw 11.

Further, in the structure shown in FIG. 4, one side wall of the recess 5 having the dovetail groove of the cement plate 1 as the base material has the shape of the dovetail groove 9 and the other side wall is vertical 13. The cement board 1 has a projection 10 at the end thereof. After the decorative plate 2 as the surface material is fitted into the recess having the dovetail groove of the cement plate 1 as the base material, between the end of the decorative plate 2 and the convex portion 10 of the cement plate 1, It is known that a fixing metal fitting having a spring 4 is fitted and fixed in parallel with the free end of the metal fitting 3.

[0005]

However, as shown in FIG. 3, the conventional mounting fitting for composite building material is the fitting 3
Since it is attached with the tapping screw 11, it is necessary to make a hole in the base material 1 and fix the metal fitting 3 with the screw 11. Therefore, it takes a lot of time and effort during the composite work, and the work efficiency is poor for forming the composite building material. In addition, since the mounting material for composite building material as shown in FIG. 4 can fix the surface material 2 simply by fitting the metal fitting with the spring, the composite work can be performed easily and the work efficiency is good. A space for mounting a metal fitting with a spring is required on the surface of 1, and the width of the surface material 2 needs to be narrower than that of the base material 1 by that amount, which is preferable from the point of covering with the surface material. Was not.

Therefore, as a result of a comprehensive study of the above-mentioned mounting metal fittings, the present inventors have found that a composite building material can be easily manufactured and that a space for mounting a spring or the like on the surface of the base material is not required. The present invention has been completed by finding out the structure and finding the structure of the base material which can be more reliably and stably attached. Therefore, an object of the present invention is to easily produce a composite building material,
Moreover, it is to provide a composite building material that does not require a space for mounting a spring or the like on the surface of the base material and is securely and stably mounted.

In the composite building material described above, the side wall of the concave portion of the base material that engages with the convex portion has a dovetail groove shape, and the side wall of the other side is vertical and has a protrusion at the outer end of the side wall. An elastic member attached to the mounting metal fitting can be fitted into a side wall recess surrounded by the protrusion, and the mounting metal fitting is installed in a space between a base material and a surface material. The elastic member attached to is fitted into a side wall recess surrounded by the protrusion of the recess of the base material, and the other end of the metal fitting is hooked and fixed to the end of the surface material. A composite building material. (2) The composite building material according to the above item 1, wherein the elastic member is either a spring coil spring or a leaf spring.

The present invention will be described in more detail below. In the composite building material of the present invention, since the mounting metal fitting is an elastic member attached to the inside of the free end of the Z-shaped metal fitting, the composite building material can be easily manufactured. In addition, it does not require a space for mounting a spring on the surface of the base material. Further, since a spring coil-shaped spring, a leaf spring, or the like is used as the elastic member, it can be securely attached. Furthermore, since the protrusion for pressing and fixing the elastic member of the mounting member is provided in the concave portion of the base material, the mounting can be performed more reliably and stably.

The composite building material of the base material and the surface material used in the present invention is used for an outer wall of a house, a building, etc. The base material is mainly a cement building material, for example, manufactured in the form of an extruded board. In addition, metal or the like is also used. The surface material may be either ceramics or cement-based material, but ceramics is preferable. The base material and the surface material are formed with a concave portion or a convex portion, and the concave portion and the convex portion have a relationship capable of fitting with each other. For example, when the base material has a concave portion, the surface material has a convex portion, and these have a fitting relationship. When the base material has a convex portion, the surface material has a concave portion, and these have a fitting relationship. One of the recesses has a dovetail shape, and the other has a fitting recess for preventing or fixing the rocking of the elastic member attached to the metal fitting. Preferably, the side wall of the recess has a fitting recess. Good to have

The fitting used in the present invention is a Z-shaped plate, and it is preferable that the horizontal and vertical parts of the fitting are at right angles. The material of this metal fitting is not particularly limited as long as it has high strength and is not easily broken,
For example, either metal such as iron or aluminum or plastic may be used. The elastic member attached or fixed to the inside of the free end of the metal fitting is not particularly limited as long as it has a large restoring force such as a spring coil spring, a leaf spring, or elastic plastic. The fitting used in the present invention can be fixed to the surface material or the base material in advance. By doing so, it is possible to efficiently perform the work without the need to prepare a mounting bracket at the time of combination. Any fixing means may be used as the fixing means, and examples thereof include an epoxy adhesive, bolts, and nails.
