Description

[Detailed Description of the Invention] The present invention relates to a long support material for a building that is used as a rafter for supporting a roof board.

Previously, JP-A-55-44832, JP-A-55-
As shown in Publication No. 7396, the cross section is hat-shaped, that is, the upper surface part and the left side hanging from the upper surface part.
The inventor of the present invention has proposed a metal support for a building that is integrally formed with a right side portion and edges projecting outward at right angles from the lower ends of the left and right side portions.

As shown in FIG. 1, the support material T is
It can be fixed to the main building A with metal band B, or
As shown in the figure, the support member T is fixed to the main building A with long screws S passing through the upper surface of the support member T.
As shown in FIGS. 1 and 2, a roof plate R is supported and fixed on a support member T.

Furthermore, as shown in Japanese Utility Model Application Publication No. 54-126409, a narrow groove is formed in the upper surface of the support member, which has an approximately hat-shaped cross section, and a tut pin screw that penetrates the plastic covering material is inserted into the narrow groove. This is done in greenhouses and other facilities.

However, the conventional supporting materials shown in FIG. 1 and FIG. When the heads H and H' protrude above the top surface and support the roof plate R, etc., if there is no gap between them and the top surface of the support material, the protruding heads H' will not support the roof plate R. There was a problem that it got in the way when roofing. In addition, when widening the width of the supporting material T to stably support it to a main building, etc., it is possible to support and fix it to the main building only by the edges protruding outward from the lower ends of the left and right sides of the supporting material. For this reason, if large forces such as snow fall act on the support materials through the roof shingles, there is a risk of them breaking or bending. However, there is a problem in that the work of attaching the supporting material becomes troublesome, and this problem was almost the same in the method disclosed in Japanese Utility Model Application No. 54-126409.

This invention solves the above-mentioned problems, prevents the heads of screws from protruding upward from the top surface, stably supports roofing boards over a wide area, and can be used as a fixing member for buildings such as main buildings. The object of the present invention is to provide a support material for buildings that can be firmly and stably supported and fixed over a wide area.

The present invention provides a support material for a building having a hat-shaped cross section, which has a depth that allows the head or nut of a fastener such as a screw for fixing the support material to a fixed member of a building to be accommodated under the upper surface part. A groove with a rectangular cross section having a width is formed over the entire length of the upper surface of the support material, and an edge of the groove bottom of the groove protrudes outward from the left and right side surfaces of the support material. In other words, the upper surfaces of the plurality of surfaces and the lower surfaces of the plurality of surfaces are each on the same plane.

Since the support material for buildings according to the present invention is constructed as described above, the head of the fastener or the nut is housed in the groove formed in the upper surface portion so that it does not protrude, and It can be fixed to a main building, etc. using screws that pass through the bottom, and the head and nuts of the fasteners do not get in the way when supporting roof plates etc. on the top, and the width of the top can be widened. The support material can stably support roof panels, etc., and even when a large load is applied from above, the support material can
It is supported by the left and right sides and both side plates of the groove, and can be fixed to the main building at three points in the width direction, at the bottom and edge of the groove, so it does not bend or break. It can be stably and firmly supported and fixed to a main building etc. over a wide area.

Hereinafter, one embodiment of the present invention will be described with reference to FIGS. 3 and 4.

In FIG. 3, reference numeral 1 denotes a long building support member made of a metal plate such as a steel plate or an aluminum plate. The right side parts 3, 3 and the edges 4, 4 protruding outward at right angles from the lower ends of the left and right side parts 3, 3, respectively, are integrally formed, and the upper part 2
A concave groove 5 having a rectangular cross section is formed along the entire length of the support member 1 in the widthwise central portion of the support member 1 . Concave groove 5
As shown in FIG. 4, the groove bottom has a depth and width that can accommodate the head H of the screw 7, and the depth is slightly shallower than the height of the side parts 3, and the lower surface 6 of the groove bottom. and the lower surface 14 of the edges 4, 4 are formed so as to be located on the same plane.

The supporting material 1 of the embodiment configured as described above is
As shown in FIG. 4, the outer lower surface 6 of the groove bottom of the groove 5 and the lower surface 14 of the edges 4, 4 are supported on the main building 9 via a heat insulating material or a roof board 10, and these are It is fixed to the main house 9 with screws 7 and 13. Further, a roof plate 8 made of a metal plate is supported on the upper surface portion 2 of the support member 1. Furthermore, a support member 11 having a hat-shaped cross section with claws is disposed between the support members 1 of the embodiment, similar to those shown in FIGS. The roof panel 8 is fixed to the roof board 8, and the roof board 8 is locked with the claw.

In the present invention, if the main building 9 is made of metal such as iron, the support member 1 can be fixed at three locations in the width direction using hook bolts and nuts as shown in FIG. In addition, the present invention is not limited to roof rafters as in the embodiment, but can also be used as a support material for fixing external wall panels of buildings, and can also be used as a replacement roof without removing existing roof panels. It can also be used when installing new roof shingles on top.
In some cases, it may also be used upside down.

As explained above, according to the present invention, the grooves 5 having a rectangular cross section are formed on the upper surface 2 of the elongated building support member having a hat shape in cross section, and the depth and width of the grooves 5 are The head of a fastener such as a screw 7 or a nut can be accommodated under the upper surface part 2, and the outer lower surface 6 of the groove bottom of the concave groove 5 and the lower surface 14 of the edges 4, 4 are placed on the same plane. In other words, since the plurality of upper surfaces and the plurality of lower surfaces are arranged on the same plane, the head of the fastening part and the nut protrude to the upper surface part 2, and the upper surface part 2 has roof plates, etc. It does not get in the way when supporting the roof, and the wide width allows stable support of roofing boards etc. on the upper surface part 2. Furthermore, the groove bottom of the groove 5 and the width direction of the edges 4, 4 It can be supported over a wide width at the fixed members of a building such as the main building 9 and fixed with screws at three points, and can withstand large loads from above, providing stable and strong support to the fixed members. This provides the effect of providing proper support and fixation.
