[0002]

2. Description of the Related Art Conventionally, a steel frame construction method (first conventional example) has been the main method used for low-rise buildings, but recently, in a convenience store, etc., a steel house construction method (a plate thickness of about 1 mm) A building having a steel-based panel structure composed of a frame material made of thin lightweight steel and a structural face material is defined as a steel house. The second conventional example) is becoming popular.

8 to 10 show a first conventional example, which is an example of a one-story building constructed by a steel frame assembly method, in which an independent foundation 1 and a floor (soil) 2 are constructed with concrete, and pillars are provided on the independent foundation 1. A (column) 3 is erected, a wall base 4 is provided to form a wall, and an H-shaped steel peripheral beam (girder) 5 is provided at the upper end of the steel-framed column 3, and the left and right peripheral beams 5 are provided. A large beam 5a made of H-shaped steel is installed between them, and the roof 6 is supported by these beams. In FIGS. 9 and 10, 4a is a wall, and 7 is a doorway (opening).

The advantages of the first conventional example are that the roof is cheap in material, has a small number of parts, is easy to process, is easy to construct on site, and can be opened freely for one day in the case of a convenience store scale ( Depending on the width of the opening, it is only necessary to insert studs) and cut the members. The disadvantage is that the construction accuracy tends to vary, and the wall requires LGS as a base for finishing,
It takes 2 days for on-site construction.

11 to 13 show a second conventional example, which is an example of a flat house such as a convenience store manufactured by a steel house (SH) method, in which a cloth foundation 8 and a floor (soil) 2 are cast with concrete, and A wall frame panel 9 made of thin lightweight steel is erected on the cloth foundation 8. As shown in FIG. 13, the wall frame panel 9 includes a lower frame member 10 made of thin lightweight shaped steel and a standing frame member 11 made of thin lightweight shaped steel, and the standing frame member 11 made of thin lightweight shaped steel. The upper frame material 12 is assembled, and each of these frame materials is a drill screw 1.
They are joined together at 9, and the structural face material 13 is attached to the standing frame material 11 to construct the structure. Hereinafter, the structural face material 1 is added to the frame material.
The one to which 3 is attached is referred to as SH panel 9a. further,
A truss (hereinafter referred to as SH truss) 14 made of thin lightweight steel sheet is assembled so as to be supported by the wall frame panel 9, and SH
The roof 6 is supported by the truss 14. In FIG. 12, 1
Reference numeral 5 is a relatively large opening (window, entrance, etc.).

As shown in FIG. 12 (A), at the upper part of the opening 15, a vertical load from the roof is applied to the wall frame panels 9 on both sides.
Both ends of the window lintel 16 for transmitting and flowing to and are supported by the lintel receiving hardware 17 and fixed to the stand frame member 11 via the lintel receiving hardware 17. 12 (B), (C)
Shows an example of a combination of window lintels 16, and shows an example in which grooved steels 16a with lips made of thin steel plates are opposed to each other and the outside thereof is reinforced with a reinforcing grooved steel 18. FIG. 12 (D),
(E) is a flat-shaped U-shaped thin steel lintel receiver 17
An example of the above is shown. Both flanges are applied to the side surface of the end of the window lintel 16 and joined with a drill screw 19 to set the web upright frame material 1
An example is shown in which it is applied to the back surface of the web No. 1 and is joined with the drill screw 19.

[0007] In the conventional example 2 (SH method), a frame material made of thin and lightweight steel is joined by using a drill screw to construct a wall frame panel of a building, and a structural face material is attached to this wall frame panel.
The structure is constructed by panels, and the advantages are that the thin steel plate structure does not require welding, cutting and drilling are easy, the members are light, and it can be carried by hand, so work efficiency is high. The cost is cheap.
As for the wall, the SH panel is easy to secure stable product accuracy, the panel is prefabricated, therefore the construction period is shortened, the panel accuracy is easy to install, and the panel construction is 0.5 days in the case of a convenience store scale. . Therefore, it is an economical structure in the structural field of low-rise buildings (typically, one-storey buildings of convenience stores).

[0008]

In addition to the advantages, the steel house construction method has the following disadvantages. Convenience stores, etc. should have large openings on the wall surface, and it is desirable to minimize the number of columns and secure a large space, that is, a large span of several meters or more is required, but a large span roof is constructed. In this case, the thin lightweight section steel has a thin section and thus lacks strength, and it is not possible to use end materials. Therefore, it is necessary to construct a roof truss composed of a plurality of members. The truss is uneconomical in that it requires a large number of members, many joints by means of drill screws, bolts, etc., and also increases the side wall area, which increases the number of processing steps. In addition, it is not possible to support a structure that is supported in a large span where the fulcrum interval of the roof exceeds 10 meters, which is required when a large indoor space is taken.

The present invention makes use of the advantages of a steel house in a single-storey building such as a convenience store, and
By adopting a part of the heavy steel frame structure, a frame structure was made up to compensate for the drawbacks of the SH method.

That is, the member is light and can be carried manually.
While utilizing the advantages of the frame material made of thin lightweight section steel used in the H method, by combining the weaknesses of strength and workability, which are its weak points, with heavy section steel, which is strong but inferior in workability, The purpose of the present invention is to provide a new frame structure of a low-rise building, which incorporates the advantages of the frame material and heavy section steel.

[0011]

In order to solve the above problems, the present invention is constructed as follows.

According to the first aspect of the invention, a wall frame panel having a lower frame member, an upper frame member and a vertical frame member made of thin and lightweight steel, and a horizontal beam member made of heavy steel frame provided at the upper end of the wall frame panel. It is characterized by a frame structure of a low-rise building in which and are joined by a joining means composed of bolts or hole-down hardware.

The invention of claim 2 is characterized in that, in the invention of claim 1, the wall frame panel and a reinforcing steel frame column are provided side by side.

According to a third aspect of the present invention, in the first or second aspect of the present invention, the wall frame panel is composed of a lower frame member, an upper frame member, and a vertical frame member made of the thin sheet lightweight structural steel, and structural face members. It is characterized by being fixedly configured.

According to a fourth aspect of the invention, in the invention according to any one of the first to third aspects, the horizontal beam member made of heavy steel frame mounted on the upper portion of the wall frame panel made of thin plate lightweight shaped steel is H-shaped. It is characterized in that it is made of steel and the H-section steel and the upper frame member are bolted to each other.

According to a fifth aspect of the present invention, in the invention according to any one of the first to third aspects, the horizontal beam member made of heavy steel frame mounted on the upper portion of the wall frame panel made of thin plate lightweight shaped steel is grooved. It is characterized in that it is made of steel, and the channel steel and the upper frame member are bolted to each other through a hole-down hardware provided by disposing a horizontal member on the upper side.

According to a sixth aspect of the present invention, the horizontal beam member made of heavy steel frame, which is placed on the upper portion of the wall frame panel made of thin and lightweight shaped steel, is made of H-shaped steel, and the H-shaped steel and the upper frame material are combined. It is characterized in that the horizontal member is bolted through a hole-down hardware provided on the upper side.

According to a seventh aspect of the present invention, in the invention according to any one of the first to third aspects, the horizontal beam member made of heavy steel frame mounted on the upper portion of the wall frame panel made of thin lightweight steel is grooved. It is characterized in that it is made of steel and the channel steel and the upper frame member are bolted to each other.

[0019]

According to the present invention, in a low-rise building, while taking advantage of the advantages of the thin-sheet lightweight shaped steel frame material used in the SH construction method in which the members are light and can be carried by hand, the weaknesses of strength and workability are Since the structure is supplemented by combining it with heavy-weight steel having strength, the steel house construction method can be used as a basic structure, while eliminating complicated structures such as roof trusses and supporting a roof load smoothly with a simple structure.

Therefore, it is desired to form a large opening in the wall surface, to minimize the number of columns, and to secure a large space. A large span of several meters or more is required. Buildings such as stores can be constructed reasonably.
In other words, in the present invention, in the steel house construction method, since the thin lightweight frame steel frame material has a thin cross section and therefore lacks strength, it is necessary to assemble a truss on the roof portion, and the structure supporting the roof is uneconomical. The problem is that the roof fulcrum spacing required to take up a large indoor space is 1
It solves the problem of not being able to support a structure that supports a large span of over a few meters.

Further, the joining method for smoothly transmitting the force between the thin steel plate frame panel and the horizontal member made of heavy steel frame supporting the roof becomes important. From the bolt joining or the hole-down hardware of the present invention, By the joining means, the force smoothly flows as an axial force in the vertical frame member of the thin plate frame panel, so that a large pulling force can be endured.
