Description

[Detailed explanation of the idea] 【Technical field】

The present invention relates to a technique for supporting rafters in a steel-frame prefabricated house by slope members, which are collective members of paving girders, purlins, and bundles.

[Background technology]

When constructing the roof of a steel frame prefabricated house using folded roofing material, a parapet may be provided along the outer periphery of the roof. Conventionally, when the end of the rafter is received at the parapet part, as shown in FIG. A sloped main building 2a was nailed to the main building 2a, and the end of the rafter 8 was placed on top of this main building 2a. However, this method has a problem in that it lacks strength when subjected to snow loads, etc.

[Purpose of invention]

This invention was developed in view of the technical background described above, and its purpose is to support the rafters so that they can bear a considerable vertical load when supporting the rafters on the outer wall. The aim is to strengthen the

[Disclosure of invention]

The support structure of the rafters of the present invention consists of a vertical bundle 3 erected between a horizontal girder 1 and an inclined main building 2 to form a slope material 4, and an external wall panel 5 erected on the upper surface, such as a beam or column. A supporting metal fitting 7 is fixed to the side surface of the frame assembly 6 of It is characterized by having a rafter 8 placed on top, thereby achieving the above object. Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The slope material 4 is shown in FIG. 3, and has a purlin 2 inclined upwardly from the horizontally installed girder 1, and between the girder 1 and the purlin 2 there are a plurality of purlins. A bundle 3 of is placed vertically. Therefore, the gradient material 4
The main building has a trapezoidal shape with two parts sloped. Vertical through holes 9 are bored in predetermined locations in the sill 1. The main building 2, bundle 3, sill 1, and reinforcing surface material 4 are made of wood, and the slope material 4 is manufactured in a factory. Also, a frame assembly 6 for supporting the gradient material 4 is provided.
means a beam or a column, but the diagram shows a beam. This frame assembly 6 (beam) is an assembled beam in which a web material is installed between a pair of channel steels, and the outer wall panel 5 constituting the frame of the parapet is erected on the upper surface of the frame assembly 6. On the indoor side surface of the framework 6, a vertical piece 13 of a long support fitting 7, which has a support 11 fixed to the inner corner of an L-shaped piece 10, is fixed with bolts and nuts 12. The sill 1 of the slope material 4 is placed on the horizontal piece 14 of the support fitting 7, and a hole is bored in the horizontal piece 14 to match the through hole 9 of the sill 1. 1 and the horizontal piece 14 are connected by bolts and nuts 15. In this way, the gradient material 4 is erected parallel to the outer wall panel 5. Furthermore, the same slope materials 4 are arranged parallel to each other inside the roof part, and rafters 8 are placed on the main building 2 of these slope materials 4 to construct the structure. A folded roofing material 16 is installed. In addition, an external wall panel (not shown) is installed between the parapet and the foundation on the ground, and the external walls of the external wall panel 5 and framework 6, which form the frame of the parapet, are finished with exterior materials. be done.

[Effect of the idea]

Since the present invention is constructed as described above, the slope material that supports the rafters can be attached directly to the frame without going through the external wall panel, and the purlin that supports the rafters is integrated as a slope material together with the beams and bundles. It has the advantage of being able to firmly support the rafters even when a large vertical load is applied to them.

Claims (1)

[Scope of utility model registration request] Vertical bundles are erected between the horizontal girders and the sloping main building to form slope materials, and supporting metal fittings are fixed to the sides of the frame structures such as beams and columns with external wall panels erected on top to support them. A rafter support structure that consists of placing sloped material on top of the metal fittings, fixing the sloped beams to the support metal fittings, and placing the rafters on top of the sloped material purlin.
