Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to an exterior or interior wall material that is nailed to the wall surface of a building.

[0002]

[Prior Art]

 Conventionally, the exterior wall material in a building such as a wooden house has a rectangular plate shape. As shown in FIG. 5, a recess 12 is formed on the entire back surface of the wall material 11 and laterally joined to at least the upper and lower ends. A waterproof sheet 16 (for example, an asphalt felt) stretched on the outer surface of a pillar 15 (or a base material such as a stud or a furring strip) is formed with a combined sleeve receiving portion 13 and a combined sleeve pressing portion 14. The wall material 11 is arranged from above and is fixed to the pillar 15 with nails 17 from the front side thereof.

A wall material whose entire back surface is flat is also used.

[0004]

[Problems to be solved by the device]

 The conventional wall material 11 has the advantage that it is lightweight, but it is weak against impact, and since there is a space, that is, a recessed strip 12, near the back surface of the nailed part, it is There was a problem with the impact resistance as well, since 18 and 19 between the recessed strips 12 were easily damaged by external pressure, lacking proof stress, and cracked due to impact during nailing. A wall material with a flat entire back surface has good yield strength and impact resistance, but has a problem that it is heavy and poor in workability, and the material cost is high and the transportation cost is high.

The present invention has been made in view of the above-mentioned circumstances, and an object thereof is to improve load resistance and impact resistance, improve workability by reducing weight, and reduce transportation cost and material cost. It is to provide a wall material that can achieve the above.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention takes the following technical means. That is, the present invention is a plate-like wall material having a concave and convex shape formed on the back surface that is nailed to the wall surface of a building, and at least the rear surface of the nailed portion is a flat surface without unevenness. It is characterized by

[0007]

[Action]

 According to the present invention, the contact area between the back surface of the nailing portion of the wall material and the vicinity thereof and the base material such as the pillar is increased, so that pulling-out resistance of nails (or screws, etc.) due to wind pressure and nailing ability are improved. Also, cracks do not occur due to bounce or vibration due to impact when nailing the wall material, the impact resistance is improved, and no excessive force acts on the joint, so it does not break.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 show a first embodiment of the present invention, in which a wall member 1 has a plate-like shape, and a mating lever receiving portion 2 is formed at an upper end thereof and a mating lever holding portion 3 is formed at a lower end thereof, respectively. The compound jamb receiving part 2 is used as a nailing part, and the compound jamb receiving part 2 and the compound jamb presser part 3 and the back surfaces 2A and 3A in the vicinity thereof are flat surfaces, except for the back surfaces 2A and 3A. There are many recessed strips 4 that extend in the left-right direction.

When the wall material 1 is attached to a building as an exterior, as shown in FIG. 2, the wall material is attached to the lower part of the outer surface of the building 5 and studs, furring strips, and other waterproof materials 6 that are stretched. 1 is applied so that the composite shed receiving part 2 is on the upper side, and nails 7 are driven from the outer surface of the composite shed receiving part 2 to fix the wall material 1 to the base material such as the pillar 5. Next, the upper part of the wall material 1 is fitted to the lower part of the wall material 1 already fixed to the pillar 5, and the upper part of the wall material 1 is fitted and locked, and the upper wall material 1 is covered with the waterproof sheet 6. Apply it to the pillar 5 through the, and drive the nail 7 into the interlocking receiving part 2 to fix the upper wall material 1, and sequentially fix the wall material 1 upward by the above procedure.

According to the first embodiment described above, the nail 7 can be hidden by the interlocking presser section 3, and the back surface 2A of the interlocking support section 2 and the vicinity thereof, that is, the back surface of the nailed portion are flat surfaces. Therefore, the area where the nailed portion of the wall material 1 comes into contact with the pillar 5 through the waterproof sheet 6, that is, the pressure receiving surface is increased, and the pulling resistance of the nail 7 (or screw etc.) due to wind pressure is improved. , The external force due to impact is dispersed and becomes small, and it is not damaged by the collision (bound) between the base material, especially the furring strip and the wall material 1, vibration, etc., and the impact resistance is improved. Unreasonable force does not act on.

FIG. 3 shows a second embodiment of the present invention, which is different from the first embodiment in that the surface near the compound receiving part 2 and the compound pressing part 3 is a nailing line. Therefore, the same operational effects as those of the first embodiment are obtained. Therefore, the same reference numerals as those in FIG. 2 are used, and detailed description is omitted. FIG. 4 shows a third embodiment of the present invention. The difference from the second embodiment is that in addition to the upper and lower nail fastening lines, a nail fastening line is provided on the surface of the central portion in the vertical direction. Since the back surface 8A and its vicinity are flat surfaces, the same operational effects as those of the second embodiment are achieved. Therefore, the same parts as those in FIG. 3 are designated by the same reference numerals, and detailed description thereof will be omitted.

The present invention is not limited to the above-mentioned embodiments, and for example, the shape of the recessed line 4 may be corrugated, and various patterns may be formed on the surface of the wall material 1. The design of the joint-joint shape can be changed as appropriate.

[0013]

[Effect of the device]

 INDUSTRIAL APPLICABILITY The present invention is a plate-like wall material in which unevenness is formed on the back surface nailed to the wall surface of the building as described above, and at least the back surface of the nailed portion is a flat surface without unevenness. Therefore, the resistance to external pressure and the impact resistance are improved, and the pressure receiving surface is increased due to the increase in the back surface contact area of the nailed part, and the external force acting accordingly is dispersed. It becomes difficult to apply unreasonable force to the joints. In addition, it is possible to improve the workability by reducing the weight, reduce the transportation cost and the material cost, and improve the durability of the wall material.
