  Hereinafter, the best mode for carrying out the present invention will be described.

  An example of the building board A of this invention is shown to Fig.1 (a) (b). The building board A is formed in a rectangular or square substantially square plate shape when viewed from the front. Moreover, this building board A is formed in the shape where the surface layer 2 and the back surface layer 4 were laminated | stacked. Both the front surface layer 2 and the back surface layer 4 are formed in a substantially square plate shape, but the front surface layer 2 and the back surface layer 4 are formed so as to be laminated with a slight shift in the vertical and horizontal directions. That is, the upper end portion of the back surface layer 4 is formed so as to protrude upward from the upper end surface of the surface layer 2, and one side end portion of the back surface layer 4 is outside (sideward) the one side end surface of the surface layer 2. The upper end portion and one side end portion of the back surface layer 4 are formed as a female 3 across the upper side and one side side of the building board A. Further, the lower end portion of the surface layer 2 is formed so as to protrude below the lower end surface of the back surface layer 4, and one side end portion of the surface layer 2 (the side end on which the female fruit 3 is not formed). Part) is formed to protrude outward (side) from one side end face of the back surface layer 4 (the side end face on which the female fruit 3 is not formed). The side end portion of the board is formed as a male 1 over the lower side of the building board A and one side side. In this way, the building board A of the present invention forms males 1 and 1 on two adjacent sides of the substantially square plate-like surface layer 2, and females on two adjacent sides of the substantially square plate-like back surface layer 4. By forming the reals 3 and 3, they are formed into a four-sided joint (joint) shape.

  Further, a plurality of hollow holes 5, 5... Are formed in the back surface layer 4 side by side in the vertical direction (vertical direction). The hollow hole 5 is formed so as to penetrate the back surface layer 4 in the lateral direction (horizontal direction), and one side end portion of the hollow hole 5 opens to one side end surface of the back surface layer 4 (the female seed 3 side). And the other side end of the hollow hole 5 is open to the other side end surface of the back surface layer 4 (opposite to the female 3). The hollow hole 5 can be formed in a cross-sectional shape such as a circle or a quadrangle (rectangular shape). Moreover, by providing the hollow hole 5, a weight can be reduced 3 to 30% compared with the solid case where the hollow hole 5 is not provided.

  Although the dimension of the building board A of this invention can be set suitably, for example, length L = 300-910mm or 1830-3030mm of the surface layer 2, the height (working width) H = 100-600mm of the surface layer 2, Overall thickness B = 16 to 60 mm, thickness b of back surface layer 4 = B / 6 to 2B / 3 (2/6 to 1/3 of overall thickness B), diameter D of hollow hole 5 = b / 10 to b / 2 (1/10 to 1/2 of the thickness b of the back surface layer 4). The joint depth X of the quasi-refractory 1 hour structure certification is X = 12 mm when there is no hollow hole 5 and the total thickness B = 25 mm, and X = 15 when there is no hollow hole 5 and the total thickness B = 35 mm. 18 mm (predicted value) is a guideline, but X = 8 mm when the hollow hole 5 is provided and the total thickness B = 25 mm, X = 12 mm when the hollow hole 5 is provided and the total thickness B = 35 mm A standard of 15 mm (predicted value) can be used.

  When constructing the building board A of the present invention, it is lifted up by combining nailing or metal fastening and an adhesive construction method on a wall base such as a column or trunk edge, and a plurality of building boards A as shown in FIG. , A... Can be arranged in the vertical and horizontal directions to form a wall such as an outer wall. Here, in connecting the building boards A and A adjacent to each other in the vertical direction (vertical direction), the lower male board 1 of the upper building board A is placed on the surface of the upper female board 3 of the lower building board A. When connecting the building boards A and A adjacent to each other in the horizontal direction (horizontal direction), the side of the female 3 on the side of one building board A and the male on the side of the other building board A are connected. Make 1 overlap. Moreover, the building boards A and A adjacent to each other in the lateral direction are arranged so that the hollow holes 5 and 5 are continuous with each other.

  In the building board A of this invention, weight reduction can be attained compared with a solid thing by providing the hollow hole 5. FIG. Therefore, this weight reduction leads to a reduction in raw materials, which can reduce the manufacturing cost. In addition, workability can be improved by reducing the weight. Further, by making the cross-sectional area the same as that of the solid one, forming the hollow hole 5 and increasing the cross-sectional modulus, it is possible to ensure the base material strength such as handling (carrying) strength and bending strength at the time of construction. Furthermore, the burden on the building frame such as the wall base can be reduced by weight reduction, and the earthquake resistance can be improved by reducing the load on the building frame.

  Moreover, the hollow holes 5 and 5 of the adjacent building board A and A can be continued, air permeability can be ensured, and generation | occurrence | production of an internal dew condensation can be prevented. That is, in a normal building board having a hollow hole (a building board that is not a four-sided joint), the hollow wooden mouth face (connection end face) of an adjacent building board is blocked by sealing, so that internal condensation may occur in the hollow hole. However, in the case of the four-sided construction board A according to the present invention, a hollow hole 5 is formed in the back surface layer 4, and sealing is provided at a connection portion between the surface layers 2 and 2 of the adjacent construction boards A and A. In order to be given, the hollow holes 5 and 5 of the adjacent building boards A and A can be made continuous without sealing. Therefore, the air permeability in the hollow hole 5 can be ensured, and internal condensation of the building board A can be prevented. Furthermore, by forming the hollow hole 5 only in the back surface layer 4 and not providing the hollow hole 5 in the surface layer 2, the risk of rainwater intrusion into the hollow hole 5, the associated quality degradation and frost damage is reduced. Can be suitably used as an exterior material exposed to rainwater.

  FIG. 3 (a) shows another embodiment. This building board A has hollow holes 5 formed in both the front surface layer 2 and the back surface layer 4. A plurality of hollow holes 5, 5... Are formed in the surface layer 2 side by side in the vertical direction (vertical direction). The hollow hole 5 is formed so as to penetrate the surface layer 2 in the lateral direction (horizontal direction), and one side end portion of the hollow hole 5 opens on one side end surface of the surface layer 2 (male 1 side). The other side end of the hollow hole 5 is open to the other side end surface of the surface layer 2 (opposite to the male 1). Other configurations are the same as those of the embodiment shown in FIG. Further, in still another embodiment shown in FIG. 3B, the hollow hole 5 is formed only in the surface layer 2 and the hollow hole 5 is not formed in the back surface layer 4. Other configurations are the same as those of the embodiment shown in FIG.

  If the hollow hole 5 is provided in the surface layer 2 of the building board A, the risk of intrusion of rainwater into the hollow hole 5 and associated quality deterioration and frost damage increases, and between the building boards A and A adjacent in the horizontal direction. When a sealing (caulking agent) is used for the vertical joint formed in the above, there is a problem that the sealing enters the hollow hole 5. Therefore, the building board A provided with the hollow holes 5 in the surface layer 2 can be mainly used as an interior material.

  The building board A of the present invention can be formed by extruding a cement composition made of cement, aggregate, reinforcing fibers, water, etc., and has two male fruits 1, 1 and female fruits. 3 and 3 can form one male fruit 1 and female fruit 3 at the same time as molding, and the other male fruit 1 and female fruit 3 can be formed by cutting or the like.

An example of embodiment of this invention is shown, (a) is a front view, (b) is a perspective view. It is a perspective view which shows the construction state same as the above. Other embodiment same as the above is shown, and (a) and (b) are perspective views. It is a perspective view which shows a prior art example.
