Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a metal base material and a metal spacer for an exterior wall finishing material in a low-rise building made of steel or wooden. In the following description, the terms "base material" and "vented rim" are used, but the term "base material" is used here to mean a rim arranged inside the outer wall finishing material. In addition, the ventilation rim refers to a rim having a hollow hollow section made of steel through which air can flow, and is used as a typical specific example of the base material. Further, the body edge generally refers to a horizontal member for attaching a wall to a siding panel or a board, but in the present invention, the wall is not limited to a horizontal one, but is a vertical one as illustrated. Is also referred to as the waistline.

[0002]

2. Description of the Related Art Conventionally, in a low-rise building of a steel frame or a wooden structure, a frame is constructed by assembling columns and beams, an inner wall is attached to the frame, a structural frame is constructed, and an outer wall finishing material is attached to the structural frame. Complete. There is a case where a heat insulating material is interposed between the structural frame and the outer wall finishing material and a case where no heat insulating material is interposed, but in any case, a base material such as a ventilation shell is provided on the back surface of the outer wall finishing material. The outer wall finishing material is fixed to the structural frame via the base material. As the base material, a wood base material (hull edge) or a lightweight shape steel base material (hull edge) is used, and each has the following advantages and disadvantages. FIG. 15 shows an example in which an outer wall finishing material 11 is fixed to a pillar material 2 via a wood base material (body edge) 9 with fasteners 6 and 12.

(A) Advantages and disadvantages of using wood as a base material for finishing materials (a) Advantages: Good workability. That is, joining is possible on all member surfaces (four surfaces), and joining with nails is possible. (B) Disadvantages: Wall deformation occurs due to aging of wood (twisting, warping, cracking, etc.). From the viewpoint of urban disaster prevention, it is not preferable to use wood as a base material for an outer wall finishing material that may cause fire spread. Even if the outer wall finishing material is made of a non-combustible material, if the wooden base material spreads due to the spread of the fire, the outer wall finishing material falls off and the structural frame is exposed to the flame. If the structural frame is made of wood, it will cause further fire spread.

(B) Advantages and disadvantages of using a lightweight section steel as the base material of the outer wall finishing material (a) Advantages: Since the members do not change over time, no deformation of the wall surface occurs. The steel base material does not burn. Therefore, if the outer wall finishing material is made of a non-combustible material, the risk of fire spread is considerably reduced even if the structural frame is made of wood. (B) Disadvantages: Workability is not better than wood. That is,
Welding or joining surface is limited, so 2
Directional bolts or self-tapping screws. It is necessary to perform electrodeposition coating or rust prevention treatment.

[0005] The advantages of (A) and (B)
There is a disadvantage, and therefore, the realization of the underlaying material for the finishing material that "the material used for the underlaying material is a metal material (steel or aluminum) and has good workability like the underlaying material for the outer wall finishing material made of wood" There are issues to be addressed.

In many cases, in the above-mentioned steel-frame or wooden low-rise building, the building is made to have a heat insulating structure. The conventional mounting structure, in which the outer wall finishing material is attached to the structural skeleton, has a base material that impairs the heat insulation performance of the heat insulating material.
There is a problem that the construction takes time, etc.
In the same manner as described above, the realization of the underlaying material for the finishing material should be solved, in which "the material used for the underlying material is a metal material (steel or aluminum material) and the workability is as good as the underlying material for the outer wall finishing material of wood" Exists as a common issue

The above [0006] will be described in detail. First, there are two types of heat insulation structures, lining heat insulation structure and outer heat insulation structure.These are briefly described.The former is one in which the heat insulating material is placed inside the structural body, and the latter is the one where the heat insulating material is placed outside the structural body. It is something to arrange. In other words, in the lining insulation structure, since the structural frame that easily conducts heat penetrates the heat insulating layer, the portion of the wall facing the structural frame on the indoor side of the outer wall is likely to be at the same temperature as the outside air temperature. However, since a portion having a temperature lower than the dew point exists on an indoor wall surface having a high temperature in winter, indoor dew condensation occurs at the portion.

In the external heat insulation structure, since the heat insulating material is located outside the structural frame, the structural frame is always the same as the indoor side, and no dew condensation occurs on the wall portion inside the outer wall and inside the structural frame. . On the other hand, a temperature difference equal to the difference between the outside air temperature and the indoor temperature occurs between the outdoor surface and the indoor surface of the heat insulating layer.However, by inserting the moisture-proof airtight film between the structural frame and the heat insulating material, the inside of the heat insulating layer is heated. The humidity can always be equal to the outside air (the dew point temperature inside the heat insulating material is kept low), so that the heat insulating material does not condense and deteriorate due to corrosion. From this point of view, for example, in a steel house or the like, there is a tendency that the outer lining insulation method is frequently used.

In the case of the external heat insulation system, when the outer wall finishing material is joined to the structural body using a fastener such as a screw or a nail, the base material presses the heat insulating material from above. In this case, since the heat insulating material is generally a material having no strength, such as an inorganic fiber type or a foamed plastic type, the heat insulating material is compressed by the base material and is deformed by compression. At the same time, the uprightness of the base material cannot be ensured, which impairs the appearance of the exterior wall finishing material. For this reason, it is necessary to devise a structure or construction so that the base material does not deform the heat insulating material.

[0010] Conventionally, in the case of joining an external wall finishing material with a wooden base material to a structural skeleton in an external heat insulation system, a heat insulating material at a portion where the base material is installed is provided so as not to deform and protect the heat insulating material with the base material. The material is notched, but in this construction method,
The cutout of the heat insulating material impairs the heat insulating function. As another base material mounting structure, a hard plastic-based cylindrical spacer with a length corresponding to the thickness of the heat insulating material is placed in the heat insulating material, and the base material is installed through this cylindrical spacer, so that the base material is installed. There is a construction method to prevent the material from being deformed by pressing the heat insulating material. However, in this case, due to the material of the cylindrical spacer, there is concern about the ability to hold the strength by joining the base material and the structural skeleton, and the plastic is a combustible material, so the outer wall finishing when fire spreads occurs Wood (non-combustible)
There is a concern about collapse (or spread of fire) of the structural frame due to falling off.

[0011]

As described above, in the case of attaching a base material for an outer wall finishing material to a structural skeleton in a steel-frame or wooden low-rise building, the material surface of the base material from wood to metal is required. In the case of the need for improvement in the structural aspect to improve the workability that becomes a bottleneck when the base material is made of metal, and when the base material is attached to the outer heat insulating material, It is an object of the present invention to improve the mounting structure of a base material for an outer wall finishing material which does not cause deformation of a heat insulating material and does not cause deterioration in heat insulating performance.
