Abstract

PROBLEM TO BE SOLVED: To improve earthquake resistance by allowing a base material of a panel composed of a plate-like steel plate to contact the outside of a building frame, and arranging the panel so as to respectively connect pairs of columns and a pair of horizontal members. SOLUTION: A panel 1 is composed of a base material 2 composed of a plate-like steel plate, a heat insulating layer 3 arranged in the whole area of a surface of the base material 2 and a covering material 4 arranged so as to cover the whole area of a surface of the heat insulating layer 3. Next, the panel 1 is arranged so as to connect mutual columns 11 being pairs and horizontal members 13, and is fixed to the columns 11, a stud 12 and the horizontal members 13 by a fixing tool α. Next, the base material 2 is allowed to come into contact will a building frame A when the panel 1 is fixed to the building frame A from the outdoor side, and is directly fixed by the fixing tool α, and the earthquake resistance of the building frame A can be strengthened. The base material 2 is hardly heated since a heat insulating layer 3 intercepts the heat even if an outer wall inside surface becomes a high temperature when an outer wall is heated by solar radiation, and since it does not expand even if a steel plate is used as the base material 2, a stable earthquake resistance can be maintained throughout the year.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wall structure for a building or a building having a wooden frame structure, in which a steel plate is used to improve earthquake resistance and form a heat insulating layer.

[0002]

2. Description of the Related Art Conventionally, there has been a method of using a brace as a means for improving the seismic resistance of a building or building frame.
However, the bracing not only becomes an obstacle when trying to fill the space inside the wall surrounded by pillars and horizontal members with heat insulating material such as glass wool, but when it is located indoors, It was prone to obstacles. In addition, bracing requires high-precision dimensions in order to give the building a predetermined seismic resistance, which requires a great deal of labor during construction.

In order to eliminate these drawbacks, a face material such as a structural plywood or a particle board having a predetermined standard size and a strength or function as a load-bearing wall is replaced with a pair of columns or pairs. There is a method of forming a wall structure by arranging the horizontal members so as to be connected to each other, and fixing the surface material to a pillar, a horizontal member, a stud, or the like with a fixture such as a nail or a screw.

[0004]

However, the wall structure formed by using the face material as described above has the following disadvantages. That is, when the face material is a structural plywood, deformation such as warpage is liable to occur due to shrinkage due to drying of water before construction, and it is easy to cause difficulty in construction and decrease in strength. Further, when the surface material is wet due to water intrusion or dew condensation, it is easily corroded, resulting in deterioration of earthquake resistance and adversely affecting the durability of the building itself. In addition, since it is bulky and heavy, it is difficult to transport it, which not only increases costs, but also leaves room for improvement in workability.

[0005]

According to the present invention, a panel is formed from a base made of a flat steel plate and a heat insulating layer disposed on one side of the base. The present invention proposes a wall structure in which the base material of the panel is in contact with the outer surface of the skeleton, and the pair of columns and the pair of transverse members are connected to each other. In addition, it is preferable to use a steel plate which has been subjected to a rustproofing process. In addition, the panel is fixed to the skeleton using a general fixture having a head such as a nail or a screw, but the head of the fixture penetrates the heat insulating layer and is located on the surface of the base material. It is something to do.

[0006]

[Function] The steel sheet does not warp due to shrinkage,
The construction is always easy because the weight is small. Moreover, since the airtightness of the steel plate is excellent, the airtightness of the entire wall is also improved. Furthermore, by performing rust-prevention processing on the steel sheet, corrosion due to water intrusion and dew condensation in the wall is prevented, and a wall structure having excellent durability is obtained. Further, since the steel plate is smaller in thickness and weight than the face material, it can be easily transported, and the wall structure can be formed at low cost.

In addition, since the heat insulating layer is formed outside the frame, the pillars, the horizontal members and the like do not form a thermal bridge, and therefore the thickness of the heat insulating layer is smaller than when the heat insulating material is provided between the columns. Excellent in economy. Furthermore, since a steel sheet having a very high moisture-proof property as compared with plywood, particle board, OSB, etc. is used as the base material disposed on the indoor side of the heat insulating layer, the moisture on the indoor side does not pass through the base material, and therefore, the outside In an environment that is often found in winter, when the temperature is low and the room is hot and humid, dew condensation does not occur near the boundary between the heat insulating layer and the base material.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The wall structure according to the present invention will be described below in detail with reference to the drawings. FIG. 1A is an example of a panel used for a wall structure according to the present invention, and FIG. 1B is an explanatory diagram of the wall structure, where A is a frame, 1 is a panel, 2 is a substrate, and 3 is a heat insulating layer. Reference numeral 4 denotes a covering material, 11 denotes a pillar, 14 denotes an interior material, 21 denotes an automatic nailing machine, 22 denotes a tip of the automatic nailing machine, and 23 denotes a hitting rod.

The panel 1 is made of a base material 2 made of a flat steel plate.
A heat insulating layer 3 disposed over the entire surface of the base material 2;
And a covering material 4 arranged so as to cover the entire surface of the surface.

As shown in FIGS. 2 and 3, the panel 1 is composed of a pair of pillars 11 and a horizontal member 1 such as a base, a beam, and a trunk.
3 and are fixed to the pillar 11, the stud 12, the horizontal member 13 and the like by a fixing tool α such as a nail or a screw. That is,
The panel 1 is arranged at the same position as a face material made of a conventional structural plywood, particle board, or the like.

The base material 2 is made of iron, aluminum, copper, stainless steel, titanium, aluminum / zinc alloy-plated steel plate, enameled steel plate, clad steel plate, laminated steel plate (such as PVC steel plate), sandwich steel plate having a thickness of 0.1 to 3.0 mm. (A vibration damping steel plate or the like) or a galvalume steel plate or the like cut into a predetermined shape, for example, about 909 mm × 2727 mm, has strength as a structural material, and has been subjected to rust prevention processing. Is preferred.

The base material 2 serves as a base on which the heat insulating layer 3 is disposed, and when the panel 1 is fixed to the skeleton A from the outdoor side, by abutting on the skeleton A and directly fixing the panel 1 with the fixing tool α. The seismic resistance of the skeleton A can be enhanced, and a wall magnification equal to or higher than the case where a face material made of a conventional structural plywood, particle board, or the like is used can be obtained.

The heat-insulating layer 3 is disposed on the surface side of the substrate 1, and is made of, for example, styrene foam (styrene board), polyurethane foam (urethane board), polyisocyanurate foam, phenol foam, vinyl chloride foam, polyethylene foam, polystyrene foam. And those made of synthetic resin foam such as urea foam, or those formed in a board shape and adhered with an adhesive or the like, or those of various soft foams, glass wool, rock wool, etc., which can be easily deformed. It consists of at least one or more.
The one in which the heat insulating layer 3 is foamed and formed integrally with the base material 2 has a high adhesive force to the base material 2 and can prevent the base material 1 from bending or warping during construction. Easy.

The covering material 4 is adhered to the surface of the heat insulating layer 3 by an adhesive or by a self-adhesive force when the heat insulating layer 3 is formed by foaming a synthetic resin. For example, asbestos paper, kraft paper, asphalt felt , Metal foil (A
l, Fe, Pb, Cu), synthetic resin sheet, rubber sheet, cloth sheet, gypsum paper, aluminum hydroxide paper, glass fiber non-woven fabric, etc., or a laminate of two or more kinds,
Alternatively, it is made of a sheet-like material subjected to a waterproof treatment or a flame-retardant treatment, or a breathable waterproof sheet. Coating material 4
Has at least one of airtightness, moistureproofness, waterproofness and the like, and prevents the heat-insulating layer 3 from absorbing moisture contained in the outside air, and also forms the heat-insulating layer 3 on the base material 2. When the synthetic resin is formed by discharging and foaming on the heat insulating layer 3
It has the role of adjusting the thickness of the.

The panel 1 is fixed to the frame A by using a striking rod 23.
Is performed using an automatic nailing machine 21 having a function of protruding from the tip 22 by a length equal to the thickness of the heat insulating layer 3.
FIG. 1B shows a state in which the striking rod 23 has protruded and the fixing tool α has been driven to a predetermined depth. By fixing the panel 1 with the fixing tool α by the automatic nailing machine 21,
Although a hole 31 is generated in the area where the head of the fixing tool α and the striking bar 23 have passed, the hole 31 becomes small due to the self-restoring property of the material of the heat insulating layer 3 and does not become a weak point of heat insulation.

As shown in FIGS. 2 and 3, the panel 1 abuts the base material 1 on the outer surface of the frame A, and
The paired horizontal members 13 are fixed so as to be connected. In addition, adjacent panels 1 are arranged with their respective side surfaces in close contact with each other.

In the panel 1, since the heat insulating layer 3 is continuously formed outside the frame A, the columns 11, the studs 12, the horizontal members 13 and the like do not form a thermal bridge, so that the heat insulating efficiency is high.
The thickness of the heat insulating layer 3 can be smaller than in the case where a heat insulating material such as glass wool is provided between the two, and the cost is excellent. Furthermore, since a steel sheet having a very high moisture-proof property is used as the base material 2 disposed on the indoor side of the heat insulating layer 3 as compared with plywood, particle board, OSB, etc., the indoor moisture does not pass through the base material 2. Therefore, in an environment where the temperature is low outdoors and the temperature is high and humid indoors, which is often seen when using heating in winter, dew condensation does not occur in the heat insulating layer 3. In addition, even when the air conditioner is in a high-temperature and high-humidity outdoor environment and the indoor air conditioner is in a low-temperature environment, the use of a material having a moisture-proof property as the covering material 4 prevents dew condensation in the heat insulating layer 3.

Further, since the heat insulating layer 3 is located outside the base material 2, the outer wall is heated by the solar radiation, and even if the inner surface of the outer wall becomes hot, the heat insulating layer 3 blocks the heat. Never be. Therefore, even if a steel plate is used for the base material 2, it does not expand, so that stable earthquake resistance can be maintained throughout the year.

Further, a heat insulating material is separately provided in the space 15 in the wall between the base material 2 and the interior material 14 to further improve the heat insulating property. The seismic resistance can be greatly improved.
