CONSTITUTION:A heat insulating board 4 is pasted to a frame body 1 composed of wood, metal or the like. A facing material 2 is fixed with screws to the frame body 1 to form an outer wall panel. An edge member 3a is fixed to the edge surface which will be the upper side of the panel after installation. A back board portion 31 is mounted projecting above the edge member 3a. Furthermore, an edge member 3b of a T-shaped cross section is fixed to the lower edge surface, and the frame body 1 is fixed to a beam through a mounting fixture so as to mount the upper panel. Consequently, water-proof performance of the horizontal joint portion can be secured.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an outer wall panel used for exterior parts such as buildings and works.

[0002]

2. Description of the Related Art Conventionally, for the purpose of streamlining construction work on the site, an exterior wall panel construction method called a curtain wall construction method has been generally used for buildings and other structures, and prefabricated houses have been panelized at a factory for housing. Exterior wall panels have been used. However, due to the high required performance of curtain walls, in order to satisfy the watertight performance, it is necessary to integrate panels with complicated shapes in the peripheral part of the panel to form the panel, and it takes time and effort to manufacture the panel. As the price became higher, the panel itself became heavier. Therefore, it cannot be used for medium-sized buildings and houses.

On the other hand, an outer wall panel used in a prefabricated house is a frame 11 made of lightweight steel with an exterior material 12 fixed thereto, as shown in FIG. When mounting this panel, as shown in FIG. 5, the frame body 11 is fixed to the beam 6 via the mounting bracket 7. Next, the joint portions of the upper and lower panels are sealed with the sealing material 15. In addition, 14 is a heat insulating material such as glass wool. However, the structure constructed by using this panel has a problem that it is difficult to secure the watertightness at the joint between the panels.

[0004]

SUMMARY OF THE INVENTION The present invention is intended to solve the above-mentioned drawbacks of the prior art.
It is an object of the present invention to provide an outer wall panel that is used for the exterior part of a building or a work piece, which is lightweight, inexpensive, and excellent in watertightness between the panels.

[0005]

According to the present invention, in an outer wall panel having an exterior material fixed to a frame body, an edge member is fixed to an end surface which is an upper side after construction, and the edge member is provided with a water return portion protruding upward. An outer wall panel provided is provided. Hereinafter, a description will be given according to an embodiment of the present invention.

FIG. 1 is a vertical sectional view of an outer wall panel of the present invention, and FIG. 2 is a horizontal sectional view thereof. Reference numeral 1 is a frame, 2 is a surface material, 3a, 3b and 3c are edge members, and 4 is a heat insulating material. The frame 1 is for ensuring the strength of the outer wall panel, and is usually provided all around the end face. When the strength is insufficient or the amount of deformation is large, the reinforcing agent 1a as shown in FIG.
Are additionally provided. Wood, metal, or the like is used as the material forming the frame. For example, when a 900 mm width, 3000 mm length, 12 mm thick fiber reinforced cement board is used as the surface material 2, the frame body 1 is 100
A lightweight steel frame C-type channel of about 50 × 20 × 3.2 is sufficient for strength.

The exterior material 2 is a material for finishing the surface of the outer wall, and is a material used for general outer wall finishing such as ceramic or metal siding material, fiber reinforced cement plate, crystallized glass, stone material, tile, metal plate. It can be used without any problems.

An edge member 3a is fixed to the end face which is located upward after the construction. The edge member 3a is provided with a water return portion 31 that protrudes upward slightly on the back surface side from the central portion, and the edge member 3a has a second cross section. A practical height of the water return section is about 15 to 100 mm. The cross-sectional shape of the edge member 3a may be L-shaped or the like. The material is not particularly limited as long as it can mold the required cross-sectional shape, and for example, ceramic materials, metal, wood, etc. are preferably used.

3b is an edge member fixed to the lower end face,
It has a T-shaped cross section. 3c is an edge member fixed to the side end surface. Ceramic materials, metal, wood, etc. are used for these edge members. These edge members 3b and 3c are not necessarily provided, and instead of providing the edge member 3b, the exterior material 2 may be extended by that amount, and instead of the edge member 3c, a post-construction sealing material is filled therein. May be. These exterior materials and edge members are usually fixed to the frame with screws.

Reference numeral 4 denotes a heat insulating material, which is not necessarily required for the construction of the present invention, but can be fixed in the panel when heat insulating performance is required for the outer wall, and the material is glass wool, A fiber-based heat insulating material such as rock wool or a foam-based heat insulating material such as urethane or foamed polyethylene is preferably used, but not limited thereto.

FIG. 3 is a cross-sectional view of a structure constructed by using the panel according to the present invention. When the frame body 1 is fixed to the beam 6 via the mounting bracket 7, the upper panel is mounted. On the other hand, the lower panel is similarly fixed to the beam 6. At the joint between the two panels, the edge member 3b of the upper panel is located at a lower level than the water return portion 31 of the edge member 3a of the lower panel. Then, the sealing material 5 is filled in the gap between the both edge members.

[0012]

The outer wall panel of the present invention forms a panel by separating and assembling a structure, a surface finish material, and an edge member that have different required performances from each other. Since the optimum design can be performed, a lean outer wall panel can be obtained. Therefore, in manufacturing, common members can be mass-produced, the manufacturing cost can be suppressed, and an inexpensive outer wall panel can be provided. Also, regarding the design of the surface, since the surface finishing material can be variously changed, the outer wall panel has a very high degree of freedom in design.

Also, regarding the weight, it is 9 as shown in the embodiment.
A panel of about 00 × 3000 mm, which is generally said to be lightweight, has a weight of about 200 kg, whereas the panel of the present invention has a weight of about 80 kg and less than half thereof. Becomes Therefore, not only the workability on site can be improved, but also the weight of the entire building can be reduced, so that the cross section of the skeleton such as columns and beams can be made small, which is a great economic not only for the outer wall construction but also for the entire construction work. Benefits are born.

On the other hand, in terms of watertightness, since the horizontal joint, which is the most problematic, has a water return portion, it is possible to secure the same waterproof performance as a general curtain wall, and the deterioration of the sealing material There is no loss of waterproofness.
