Next, the webs 5a, 6a are arranged vertically on a slope of the roof to be corresponded to them. Then, lower side flanges 5b, 6b of the webs 5a, 6a are brought into contact and welded together. A band 7, serving as a connecting member, is provided in upper side flanges 5c, 6c. An angle rafter beam 1 is formed by integrally fixing end parts of the band 7 to the C-shaped materials 5, 6 by welding. Further, a metal fixture is welded to predetermined positions of the upper side flanges 5c, 6c. In this way, mounting work can be easily executed by substantially constituting the angle rafter beam as a single beam.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a corner beam that can be used at the boundary of adjacent roofs sloping in different directions in a hipped roof, a square roof, etc.

<Prior Art> For the frame of a sloped roof in a steel-frame building, H-shaped steel members are generally used as the ridge beam and diagonal beam due to strength or construction issues.

When roofs sloping in different directions are constructed adjacent to each other, such as a hipped roof or a square roof, the corner beams used for the sloping ridges that form the boundaries of these roofs should be aligned with the slopes of the corresponding roofs. Preferably, the surfaces are parallel. However, for this purpose, it was necessary to prepare a corner beam with a complicated shape.

<Problems to be Solved by the Invention> The purpose of the present invention is to maintain the positional accuracy of fasteners such as roof panels by integrating two C-shaped members, and to facilitate the installation work. It provides corner timber beams.

<Means for Solving the Problems> In order to solve the above problems, a corner beam according to the present invention is a corner beam used at the boundary between adjacent roofs sloping in different directions in a hipped roof, a square roof, etc. The webs of the two C-shaped members are arranged perpendicularly to the slopes of the respective roofs, and the webs of the respective C-shaped members are arranged oppositely,
Further, the two C-shaped members are brought into contact with each other on the lower flange side and fixed together, and the upper flange side is fixed via a connecting member.

<Function> According to the above means, the webs of the two C-shaped members are arranged perpendicularly to the slopes of the corresponding roofs, the webs are brought into contact with each other facing each other, and the webs are placed on the upper flange side of the C-shaped members. A connecting member is arranged to connect the webs at the abutting portion, and each C
By welding the abutting parts of the shape and the connecting member,
The two C-shaped members can be integrated.

Also, since the corner beam is essentially constructed as a single beam,
The corner beam can be connected between the ridge end and part of the roof corner in one installation operation.

<Example> A corner beam to which the above-mentioned means is applied will be described below with reference to the drawings.

1 [D is an explanatory view of the corner beam seen from the direction perpendicular to the web of one C-shaped member, Fig. 2 is an explanatory plan view, and Fig. 3 is the second
Fig. 4 is an explanatory diagram of the frame structure of a hip type roof.

First, a roof frame structure in which the corner beam according to the present invention can be suitably used will be explained with reference to FIG.

This figure shows an example of a roof plan of a hipped type in a steel structure building. A plurality of diagonal beams 3 are disposed, and a diagonal beam 2 is disposed on an extension of the ridge beam 4. Further, a plurality of corner beams 1 are arranged from the ridge ends A, which are both longitudinal ends of the ridge beam 4, toward a part of the corner of the roof. The present invention relates to the corner beam 1.

Next, the specific structure of the corner beam 1 will be explained.

As shown in FIGS. 1 to 3, the corner beam 1 is constructed using two C-shaped members 5.6 having dimensions corresponding to the length of the ridge of the roof. As this C-shaped member, it is possible to use light channel steel, lip channel steel, or the like, and it is also possible to use channel steel.

The C-shaped members 5.6 are arranged such that the webs 5a, 6a are opposed to each other, and the webs 5a, 6a are perpendicular to the slope of the corresponding roof;
6 are brought into contact with each other at the lower sides of the webs 5a and 6a, that is, at the lower flanges 5b and 6b, and are integrated with each other by welding the corresponding contact portions. Therefore, the C-shaped members 5.6 are mutually configured in a fan-shape with the abutting portion as the center. C-shaped member 56
In order to maintain the above-mentioned shape, a band 7 serving as a connecting member is provided on the upper flanges 5c, 6c side of the section 5.6, and the ends of this band 7 and the C sections 5, 6 are connected. Fixed by welding.

The corner beam 1 constructed by integrating the C-shaped members 5 and 6 as described above has a triangular cross-sectional shape as shown in FIG. Therefore, even if an external force is applied to the upper flanges 5c, 6c, the corner beam 1 will not be deformed (therefore, it is possible to accurately maintain the angle formed by the webs 5a, 6a, In addition, it is possible to maintain the perpendicularity of the webs 5a, 6a with respect to the corresponding roofs.Also, since the webs 5a, 6a maintain the perpendicularity with respect to the corresponding roofs as described above, the upper flanges 5c, 6c is parallel to the slope of the corresponding roof.

Fasteners 8 are fixed to the upper flanges 5a, 6a of the corner beam 1 in accordance with the dimensions of the roof board to be attached to the corner beam 1 or the mounting pinch of the main building to be attached. The shape of this fastener 8 is not particularly limited, and has a shape that corresponds to the roof board or main building attached to the corner beam 1. In this embodiment, a roof plate is attached to the corner beam 1, and the stopper 8 is an angle material cut to a predetermined length and attached to the upper flange 5.
It is welded at the predetermined position of c and 6c.

When fixing the fastener 8 to the upper flanges 5c and 6c of the corner beam 1, the fastener 8 has a particularly complicated shape because the flanges 5c and 6c maintain parallelism to the corresponding slope of the roof. (It can be formed by simply cutting the angle material to a predetermined length, and by fixing this angle material to the upper flanges 5c and 6c by welding etc., it can function as the stopper 8. It is possible to demonstrate this.

One end 1a of the corner beam 1 is arranged on the ridge edge A side of the roof and joined to other members, and the other end 1b is arranged on the corner side of the roof and joined to the upper part of the pillar of the building. be done.

In this embodiment, the end portion 1a of the corner beam 1 on the ridge end A side includes:
A joining member 9 for joining with the diagonal beam 3 serving as another member is fixed. This joining member 9 is made of an angle material with mounting holes 9a formed at predetermined positions and attached to the lower flange 5b of the corner beam 1.
, 6b, respectively, by welding. That is, since the lower flanges 5b and 6b of the corner beam 1 are constructed parallel to the flange surfaces of the adjacent diagonal beams 2 and 3, the connecting members made of angle materials are fixed to the lower flanges 5b and 6b of the corner beam I. By doing so, it becomes possible to easily join the beam 1 to the diagonal beam 2.3.

<Effects of the Invention> As explained in detail above, according to the corner beam according to the present invention, the webs of two C-shaped members are arranged perpendicularly to the slopes of the corresponding roofs, and the webs are brought into contact with each other. Since the corner beam was constructed by arranging and integrating the connecting members, each C
It is possible to maintain the mutual mounting positional accuracy of the roof plate fasteners fixed to the upper flange of the profile.

Further, the upper and lower flanges of the corner beams are parallel to the slopes of the corresponding roofs, so that they can be easily joined to adjacent diagonal beams.

Also, since the corner beam is essentially constructed as a single beam,
Since the corner beam can be connected between the ridge end and a part of the corner of the roof in one installation operation, the installation operation can be easily carried out.
