DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hollow extruded plate used for laterally lining an outer wall of a building.

[0002]

2. Description of the Related Art A hollow extrusion molded plate for an outer wall in which a plurality of hollow portions parallel to the longitudinal direction are provided in two stages in the thickness direction has been conventionally known. Since it is supposed to be used, the joint structure is designed so that the end face in the width direction is fitted with a groove and a ridge, but the end face in the longitudinal direction is extruded. It was a plane that was cut at the time of, and its shape was not devised. Even if some contrivance is made, since the end face in the longitudinal direction is the end face formed by cutting when manufacturing by extrusion molding, it is practically impossible to make it into a special shape.

[0003]

Since the conventional hollow extrusion-molded plate for outer wall has the above-mentioned shape, it is formed from joints, especially lateral joints (joints of end faces in the longitudinal direction of the hollow extrusion-molded plate). It was difficult to completely prevent the ingress of water.

SUMMARY OF THE INVENTION The present invention relates to a fiber-reinforced cement having a plurality of hollow portions parallel to each other in the longitudinal direction, and a hollow extrusion-molded fiber-reinforced cemented material having two hollow portions in the thickness direction. It consists of a system hardened plate, and the end face shape in the longitudinal direction is a shape that can be joined with the hardened plate adjacent in the width direction and can be joined,
Along with a central partition wall in the central portion in the thickness direction, it relates to a hollow extruded molded plate for laterally extending outer wall in which a sealing material is provided on the entire peripheral surface or three peripheral surfaces excluding the lower surface or two peripheral surfaces of the upper surface and one side surface. By using this hollow extruded plate as an outer wall of a building with horizontal lining, it is possible to completely prevent intrusion of water from joints.

In the present invention, the shape of the end face in the width direction of the forming plate whose end face shape can be devised is made into a hiccup shape, and the main point is to attach this forming plate to the building by laterally lining it. Further, a sealing material is provided on the peripheral surface along the central partition wall at the central portion in the thickness direction of the molded plate to completely stop water at the central partition wall.

In the present invention, the sealing material provided along the central partition wall at the central portion in the thickness direction is for preventing the infiltration of water from the outdoor side at the joint between the adjacent molding plates. It is meaningless to provide the end faces located at the upper and lower ends or the left and right ends when used as an outer wall, and the end faces of the ends can be stopped by the usual method. On the surfaces other than the ends, it is only necessary that the end surfaces of the molded plates are joined to each other via the sealing material. Therefore, when looking at one molded plate, it is provided on the two peripheral surfaces of the upper surface and one side surface. If the condition is satisfied. From the viewpoint of improving productivity and securing further waterproofing by standardizing products, it is preferable to provide it on the entire peripheral surface or on the three peripheral surfaces excluding the lower surface, especially on the three peripheral surfaces excluding the lower surface. Is preferred.

The fiber-reinforced cement-based hardened board of the present invention is produced by mixing various reinforcing fibers into cement mortar and performing hollow extrusion molding. As reinforcing fibers, short fibers and long fibers are used. (Continuous yarn, knitted fabric, nonwoven fabric, etc.) are used, but when long fibers are used, they are continuously inserted into cement mortar during extrusion molding.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings.

FIG. 1 (a) is a cross-sectional view of the hollow extrusion molded plate of the present invention taken along a plane orthogonal to the longitudinal direction, and FIG. 1 (b) shows the upper and lower joints of the hollow extrusion molded plate of the present invention. The same cross section is enlarged except for a sealing material. Hollow extruded plates are indoor side wall 1A, outdoor side wall 1B, intermediate wall 1
C, it has a plurality of indoor side hollow portions 2A and a plurality of outdoor side hollow portions 2B which are constituted by the width direction partition walls 9 and are partitioned by these walls. Regarding the width direction of the hollow extruded plate, one side projects from the indoor side to the outdoor side to form the indoor side overhanging portion 4, and the other side projects to the outdoor side from the indoor side to form the outdoor side overhanging portion 5. However, the adjacent indoor-side overhanging portion 4 and the outdoor-side overhanging portion 5 are shaped so that they can fit together and be joined by hiccups. A sealing material 3 is provided on the entire peripheral surface around the intermediate partition 1C. A usual annular rubber gasket is used as the sealing material 3, but the material is not limited to rubber. Since the sealing material 3 is adhered around the intermediate partition 1C, it is preferable that the cross section is not a perfect annular shape but a shape in which a part of the annular shape is flat or a shape in which a foot is further added thereto. Accordingly, it is preferable to provide the sealing material mounting groove 6 on both sides of the intermediate partition wall 1C.
The sealing material 3 is also bonded to the intermediate partition wall 1C on the longitudinal end surface of the hollow extruded plate, but since the longitudinal end surface is flat immediately after extrusion molding, the intermediate partition wall 1C on the longitudinal end surface before the sealing material 3 is bonded. It is preferable to provide notch grooves on both sides of the plate. It is preferable to provide a concave groove 7 on the lower surface of the outdoor-side projecting portion 5 for the purpose of inserting a backup material at the time of injecting the joint material and inserting a rain barrier. FIG. 1 (a) shows an example in which the sealing material 3 is provided on the entire peripheral surface. However, when the hollow extruded molded plate is mounted horizontally, the surface having the outdoor side protruding portion 5 which is the lower surface has already been mounted. Since the sealing material 3 can be placed on the hollow extruded plate while pressing it by gravity, it is possible to sufficiently secure the seal between the upper and lower hollow extruded plates without providing the sealing material 3 on the lower surface. The sealing material 3 may not be provided on the lower surface. The sealing material 3 may not be provided on the side of the side on which the hollow extrusion molded plate is already attached and the sealing material 3 is provided on the joining surface.

FIG. 2 shows a joint portion of the hollow extrusion molded plate of the present invention in which a sealing material 3 is provided around an intermediate partition wall 1C having three peripheral surfaces other than the lower surface. (A) is a vertical sectional view, (b) is a sectional view. Is a horizontal sectional view. As shown in (a), the gap between the lower surface of the hollow extruded plate placed above and the lower surface of the hollow extruded plate placed above is blocked by the elasticity of the upper surface of the sealing material 3 of the hollow extruded plate placed below. A rain barrier 16 is inserted and bonded in the groove 7. As shown in (b), the gap in the longitudinal direction (left and right) of the hollow extruded plate is closed by two sealing materials 3 and 3.

3A and 3B show a joint portion of the hollow extrusion molded plate of the present invention in which a sealing material 3 is provided around the intermediate partition wall 1C on the entire peripheral surface. FIG. 3A is a vertical sectional view and FIG. 3B is a horizontal sectional view. It is a figure. The gap between the upper and lower hollow extruded plates and the gap in the longitudinal direction (left and right) are closed by two sealing materials 3 as shown in (a) and (b), respectively. A rain barrier 16 is inserted and bonded in the groove 7. The end of the hollow portion is blocked by a hollow portion sealing material 17. As the hollow portion sealing material, a molded product of rubber or plastic, which conforms to the shape of the hollow hole, or a putty such as mortar or resin is used.

FIG. 4 shows another joining example of the hollow extruded molded plate of the present invention in which the sealing material 3 is provided around the intermediate partition wall 1C having three peripheral surfaces other than the lower surface, and an example of attachment to the body. (a) is a vertical sectional view, (b) is a horizontal sectional view.
As shown in (a), the gap between the upper and lower hollow extruded plates is closed by the sealing material 3. The cross joint is formed by inserting and bonding a backup material 14A to the concave groove 7 and injecting the joint material 15A into the outdoor side. As shown in (b), the left and right gaps are closed by two sealing materials 3, 3. First of all, the backup material 1
4B is inserted, and then the joint material 15B is injected from the outdoor side thereof. Hollow extruded plate is 1 in every 3 stages
It is supported by a weight receiving angle 13 protruding from 0, and is attached to the skeleton 10 by screwing a nut 12 onto a bolt 11 attached to the skeleton 10 side through a mounting hardware 11A. When the nut 12 is screwed, the indoor hollow portion 2A is used.

FIG. 4 shows an example in which the backup material is inserted into both the vertical joints and the horizontal joints and the joint material is injected, but when joining the hollow extrusion molded plate of the present invention, The joint material may be injected in both lateral directions, the joint material may be injected only in any one direction, or the joint material may not be injected in both directions. When the horizontal joint is not formed, it is preferable to insert and adhere the rain barrier 16 to the concave groove 7 to prevent rainwater from entering.

In the hollow extruded sheet of the present invention, the sealing material is provided on the two circumferential surfaces, the three circumferential surfaces,
Any of the entire peripheral surface may be used. Then, at the time of construction, the gap of the outdoor side joint may or may not be blocked by the joint material. Further, the hollow portion may or may not be closed at the end. Therefore, there are various different embodiments in manufacturing and constructing the hollow extruded plate of the present invention.
