Frame construction for low-rise building

Abstract

A frame construction for a low rise building. In the construction, a wall frame panel is made of thin light-gauge section steel by bonding together a surface member, a lower frame member, vertical frame members and an upper frame member. Roof or floor support girders are made of heavyweight section steel having H-shape or channel shape. The girders are coupled to frame construction panels by bolts or hold-down fasteners.

Benefits of technology

[0036] Further, another object of the present invention is to provide frame construction which maintains the advantage of the frame members of thin light-gauge section steel used in the SH method in that it is light in weight and capable of being manually conveyed; and eliminating the drawback thereof in that it is inferior in strength, by combining the same with heavyweight section steel which is inferior in execution property and heavy in weight.

[0041] According to yet a further embodiment of the present invention, in the low-rise building constructed by the SH method using frame members of thin light-gauge channel steel, the problem of the thin light-gauge section steel, that it is weak in mechanical strength and inferior in processibility, may be solved by combining the same with heavyweight section steel, while maintaining the merit thereof in that it is light in weight and capable of being manually conveyed, it is possible to smoothly support a roof load by a simple construction based on the steel house method without using a complicated structure such as a roof truss or others.

[0043] Also, the coupling method can be useful for smoothly transmitting a force between the horizontal member of heavyweight steel frame for supporting the roof and the assembled panel of thin steel frames.

[0044] According to yet another exemplary embodiment of the present invention, a force may be transmitted as an axial force to vertical frame members of the assembled panel of thin steel frames, whereby the arrangement can be durable against a large withdrawing force.

[0051] According to a still further exemplary embodiment of the present invention, by constituting the girder disposed above the force-resisting wall panel with heavyweight steel such as H-shaped steel or channel steel, or the assembled members of thin light-gauge channel steel, it is possible to eliminate the lintel in the low-rise building, whereby it is possible to enlarge the height and width of the opening due to the elimination of lintel, while maintaining the advantage of the method for constructing the steel house mainly formed of frame members of thin light-gauge section steel in that no welding is necessary, cutting and boring are simple, the working efficiency is high, because the material is light in weight and can be manually conveyed, the force-resisting wall panel, the roof and the floor panel are efficiently manufactured in the factory at a high accuracy, the site work is simplified, the construction period is short, and the manufacturing cost is low.

Problems solved by technology

However, drawbacks thereof are that the precision of execution of work is liable to vary; LGS (light-gage steel) is necessary as a substrate for finishing the wall; and site work needs two days.

That is, in the building, when a roof of large span is constructed in correspondence to a required large span of several meters or longer, as the cross-section of the thin light-gauge section steel is small, the strength thereof is too weak to support a load from the roof solely by the end members.

In the above-mentioned roof truss, the number of parts increases, the number of portions to be coupled by drill screws or bolts increases, and an area of the side surface wall increases, which are uneconomical because of the increase in man-hours.

Also, when it is required to guarantee a large room space, the second prior art method could not respond to a case in which the span between supports of the roof is as large as ten or more meters.

Thereby, the lintel preferably uses a member in which a plurality of thin light-gauge section steel pieces are combined to result in the complexity of the manufacture and construction of the lintel.

Further, when the opposite ends of the lintel are attached to the side ends of the force-resisting wall panel disposed on both sides of the opening, the attachment of the lintel to the peripheral members becomes complex in relation to complexity in the structure of the lintel.
