Description

The present invention relates to a laminated panel used for a wall material, a floor material, a ceiling material, a roof material, and the like of various structures such as a wooden structure, a steel frame structure, and a reinforced concrete structure. The present invention relates to a laminated panel structure which is excellent in waterproofness and airtightness of panel joints and the like, is particularly suitably used for a frame structure, is suitable for pre-production in a factory, and can easily realize a highly durable house.

[Conventional technology]

In recent years, for example, in the case of a residential structure, various structural elements such as pillars and wall materials are produced in a factory in advance, and assembled at a construction site, thereby facilitating construction work and shortening the construction period, For the purpose of reducing the number of (carpenters), so-called two-by-four houses (prefabricated houses) are widely adopted.

In addition, a part of the structure is pre-produced in a factory or the like, so that the labor of measuring and processing at a construction site is omitted.

In this case, each panel such as a wall material, a floor material, a ceiling material, a roof material, etc., which is pre-produced according to a certain standard, is appropriately selected and purchased and carried to a building site, or pre-produced in a predetermined size according to an order. A panel such as a wall material is carried into a construction site, and the panel such as the wall material is attached to a column material, a frame member, a structural frame material, or the like at the construction site.

In particular, in recent years, structural panels have been developed, and panels having improved heat insulating properties have been used as panels such as wall materials.

For example, as shown in FIG. 8, a glass wool 100 is attached to the back side of a plate material 100 (see Japanese Patent Publication No. 53-9003), or paper or the like is placed on the front and back of a wooden frame 102 as shown in FIG. There is a known one in which a foam heat insulating material is injected into the wooden frame 102 in advance (see Japanese Utility Model Laid-Open No. 62-1928).

These panels, such as wall materials, are pre-produced in factories in a size that takes into account the ease of transportation and construction. For example, when constructing the walls of a structure, a plurality of wall material panels must be To form one wall.

[Problems to be solved by the invention]

However, as described above, when the wall surface or the like is configured by a plurality of wall material panels or the like, a connecting portion (joint) of the panel,
A gap is likely to be formed at a joint portion with another constituent member such as a column member or a floor member, and the heat insulating effect is reduced.

In particular, in the winter season, since cold air enters through the gap, there is an inconvenience that the resident is forced to spend a large amount of heating expenses to maintain the living environment.

In addition, the moisture in the room is condensed by the cold air in or near the gap, between the outer wall and the inner wall, or under the floor.

Such dew condensation penetrates the inside of a panel such as a wall material or the like from the above-mentioned gaps, or a column material, and promotes the breeding of bacteria and fine substances.
The structural members such as the wall members and columns are corroded. As a result, there are inconveniences such as shortening the life of the building.

In order to prevent the above-mentioned corrosion of structural components, a moisture-proofing agent is applied to wall materials, columns, beams, and the like, and moisture-proofing is performed on the high-quality structure itself, but the cost is enormous and unusual. .

Also, the life of conventional wooden houses is said to be 10 to 20 years, and today there is a strong demand for effective use of timber resources. I have. For this reason, many construction methods have been developed to realize a highly durable house with a high heat insulation and high airtight structure. Panels cannot be used frequently, and the construction becomes complicated and the number of processes increases, resulting in a long construction period. In the case of using the above panels frequently, it is necessary to apply putty etc. to the gaps at the joints etc. In addition to the cost of material such as putty, the painting process is required, and the above panels must be mounted without any gaps, which requires special construction techniques.

This situation has hindered the spread of durable homes to the general public, as building costs eventually bounced back.

In particular, recently, the shortage of craftsmen in the construction industry has become a serious problem, and is in a form that goes against the actual situation of the above, which has further hindered its spread.

The present invention has been proposed in order to solve the above-mentioned various inconveniences and problems, and is intended for joints with other structural members such as joints such as wall materials and columns and floors other than laminated panels. It is an object of the present invention to provide a laminated panel structure which can prevent dew condensation occurring in the above and can be easily constructed in a short construction period by a simplified construction method, and can widely spread inexpensive and highly durable houses to the general public.

[Means for solving the problem]

In order to achieve the above object, the present invention comprises a heat insulating material interposed between a pair of plate materials, and joining a laminated panel having both ends of at least one plate material protruding from the heat insulating material to a structural member. A laminated panel structure, wherein at least between the heat-insulating material end face and the structural component, a moisture-proof resistance value has a moisture-proof property of 50 m ² hmmHg / g and an airtight moisture-proof moisture-proof packing material having compressible elasticity. It is characterized in that at least a part of the structural member is fitted between the plate members, or the end surfaces of the plate members are brought into contact with each other.

As the pair of plate materials used for the laminated panel in the present invention, various types of plate materials for building, such as a steel plate, a rigid resin plate, a laminate obtained by mixing and laminating wood pieces and a rigid resin, and a laminate of thin plates (a plywood) are used alone or in combination. Can be used, especially 4
A plywood of 曲 げ 18 mm is preferably used, and a plywood having a bending rigidity of 8 × 10 ³ kgcm or more as a laminated panel is preferable.

In addition, the dimensions of the plate material are usually about 500 to 1500 mm (preferably a fixed length of 910 to 1220 mm) and 1820 to 3000 mm in length.
Degree.

Examples of the heat insulating material interposed between such a pair of plate materials include various foams such as urethane foam, styrene foam, polyethylene foam, phenol foam, vinyl chloride foam, and rubber foam, and various fiber materials such as glass wool and rock wool. An organic or inorganic heat insulating material such as the above is used, and preferably has a shear rigidity of at least 20 kg / cm.

Among them, synthetic resin foams such as rigid polyurethane foam and polystyrene foam are preferably used, and the thickness thereof is suitably 20 to 50 mm.

Further, as the hermetic and moisture-proof packing material, various organic foams such as rubber foam, vinyl chloride foam, asphalt-impregnated soft urethane foam and polyethylene foam having moisture-proof property and compressible elasticity are preferably used. Those with a resistance value of 50 m ² hmmHg / g or more are used.

The thickness of the airtight and moisture-proof packing material varies depending on the size of the laminated panel of the present invention, the mounting position of the laminated panel of the present invention, and the like, and cannot be unconditionally determined, but is usually preferably about 3 to 30 mm. .

In the laminated panel of the present invention, both ends of at least one of the pair of plate members protrude from the heat insulating material, but the protrusion length is preferably about 10 to 100 mm.

When both of the plate members protrude from the heat insulating material, the protruding length of each plate member may be different.

Further, since the projection of the plate material only needs to project from the heat insulating material, the thickness of the airtight moisture-proof packing provided on the heat insulating material may be the same as the length of the projection of the plate material.

In addition, in this invention, a structural component is a pillar,
Refers to components of various structures such as frame members and structural frame materials.

[Action]

In the laminated panel of the present invention, an airtight and moisture-proof packing material is provided on a laminate in which a heat insulator is interposed between a pair of plate materials and each plate material, so that the laminate is pre-produced in a factory.

The air-tight and moisture-proof packing material is usually provided by attaching it at a factory or the like when manufacturing a laminate comprising the above-described pair of plate members and a heat insulating material. It can also be provided by attaching to the contact surface as described above or by temporarily attaching.

One or a plurality of laminated panels such as wall materials are formed by air-tight and moisture-proof packing materials provided at the ends of the laminated panels on columns, frames, structural frames, etc. as part of the structure by field workers. It is mounted by pressing on other structural components such as other laminated panels or columns, frames, beams, window frames, door frames, and the like.

At this time, the laminated panel is firmly fixed to columns, frames, structural frames, etc., and due to the structural strength of the laminated panel itself,
The robustness of the structure itself is also ensured.

When one wall surface is constituted by a plurality of laminated panels, the laminated panels may be attached via a shaft assembly, or the wall surfaces may be formed without a shaft assembly, and each laminated panel may be laminated on the shaft assembly. The panel is fixed to secure the strength.

Since the hermetic moisture-proof packing material has elasticity as described above, a gap is prevented from being formed in a contact surface between the laminated panel and another structural component other than the laminated panel or the laminated panel, and It acts to prevent the ingress of water and the passage of moisture.

As described above, the laminated panel of the present invention can be applied to a structure using the laminated panel, such as putty coating or the like, on a joint surface between the laminated panels or a boundary portion between the laminated panel and another structural component. High watertightness / airtightness / moisture proofing effect between the inside and outside of the laminated panel without going through various steps.

By this action, for example, in the winter season, especially in a cold region, the occurrence of dew condensation at the above-mentioned joint surface or boundary is prevented, and corrosion of the high structural component is prevented.

The above-described effects are not exhibited even when the thickness of the airtight moisture-proof packing material in the laminated panel of the present invention is too thin, and when the thickness is too large, mounting work of the laminated panel of the present invention becomes difficult. Usually, it is about 3 to 30 mm.

〔The invention's effect〕

Since the present invention constitutes walls, floors, and the like only by connecting and fixing the laminated panels, not only the base step is unnecessary, and the construction period can be shortened, but also an airtight and moisture-proof packing material is provided at the end of the laminated panels. Therefore, there is no gap between joints between the laminated panels and joints with other structural members such as pillars and flooring, so that the airtightness is improved and the heat insulating effect of the structure can be further improved. Thus, a structure with low heating cost can be realized.

In addition, for example, in winter, particularly in a cold region or the like, it is possible to prevent dew condensation occurring in or near a gap such as a joint, between an outer wall and an inner wall, or under a floor or the like. Corrosion of structural members such as the above can be prevented, and the life of the building can be extended.

In addition, since it is not necessary to apply a moisture-proofing agent to wall materials, columns, beams, and the like and to perform moisture-proofing on the structure itself, it is possible to reduce the construction cost of the structure.

Furthermore, the laminated panel of the present invention, which is easy to construct, can be positively used in a highly durable house. As a result, no draft or dew is generated. The structure can be realized.
