Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a joining structure in which diagonal beams disposed at a predetermined angle of inclination are butt-joined at their tops.

Techniques such as those disclosed in Japanese Patent No. 175108 have been proposed. The former technique relates to a connection structure in which when one through-beam is connected to another beam orthogonally, the upper flanges of each beam are located on the same plane. The latter technique relates to a connection structure in which beams arranged in two orthogonal directions centering on a column are connected to the column by positioning their respective upper flanges on the same plane.

The frame of the roof of a building with a sloping roof is constructed by forming a gassho with diagonal beams tilted according to the inclination angle of the roof, and joining this gassho with a ridge beam. As a technique for joining the ridge beam and diagonal beam in the roof structure as described above, Japanese Utility Model Application No. 5921315 or No. 59-
As shown in Japanese Patent No. 21317, a technique has been proposed in which a mounting plate is fixed to a ridge beam and a diagonal beam is attached to the mounting plate with bolts or the like.

<Problems to be Solved by the Invention> Among the above-mentioned conventional techniques, the technique shown in Japanese Utility Model Application Publication No. 62-175106 and Japanese Utility Model Application Publication No. 6H75108 forms the flange surfaces of each beam on the same plane. Therefore, it cannot be used in cases where the beams have a predetermined inclination angle to each other, such as in the framework of a roof.

Utility Model Publication No. 59-2131.5, No. 59-21317
The technology disclosed in the publication relates to a roof frame structure. In each of the above-mentioned techniques, a wing plate, a mounting plate, or the like is used as a joining member between the roof frame horizontal member and the roof frame diagonal member. These wing plates and mounting plates have complicated shapes, and the work of fixing the wing plates to the vertical members and the fixing work of the mounting plate to the horizontal members is also complicated, making it impossible to maintain installation accuracy at a certain level. There is a possibility.

An object of the present invention is to provide a joint structure for a diagonal roof top that has a simple structure and can easily perform roof frame work.

<Means for Solving the Problems> In order to solve the above problems, the joining structure of the diagonal fruit apex according to the present invention includes H-shaped diagonal beams that have a predetermined inclination angle and are arranged with their end faces facing each other. A joining structure at the top of the H-shaped diagonal beam, one of the joining members having a T-shaped cross section with mounting holes formed at predetermined positions on a predetermined surface of the web of the H-shaped diagonal beam at the top end of the H-shaped diagonal beam. The flange of the IJ type diagonal beam is made to protrude from the end face of the H type diagonal beam, and the web of the joining member is made to protrude from the web of the H type diagonal beam and fixed, and the top end of the IJ type diagonal beam is made to face each other, and the web of the joining member is made to protrude from the end face of the H type diagonal beam. It is made by joining.

<Operation> - According to the means described in F, H-shaped diagonal beam (hereinafter simply "diagonal beam")
A joining member having a T-shaped cross section with mounting holes formed for inserting bolts into predetermined positions of the web and the flange is attached to a predetermined surface of the diagonal web at the top end of the flange. By making the web protrude from the beam and making the web protrude from the web surface of the diagonal wire and fixing it, the protruding flange and web can be configured as a connecting piece.

Then, the tops of the diagonal beams to which the joining members are fixed as described above are faced and butted together, and the diagonal beams are fixed at a predetermined angle by joining them using ports, nuts, etc. through the mounting holes formed in the joining members. It can be held and joined.

In the diagonal beams joined as described above, since the webs of the joining members each protrude in a direction perpendicular to the axial direction of the diagonal beam, the ends of the ridge beams can be joined to these webs. and diagonal beams can be joined at right angles.

<Example> A top joint structure of a diagonal beam to which the above-mentioned means is applied will be described below with reference to the drawings.

This figure shows an example of a hipped type roof plan in a steel structure building, with a plurality of ridge beams 2 arranged on the ridge, which is the top of the roof, on both sides of the ridge beams 2. A plurality of diagonal beams 1 are disposed facing each other, and a plurality of corner beams 3 are disposed from both longitudinal ends of the ridge beam 2 toward the corners of the roof.

The diagonal beam 1 is orthogonal to the ridge beam 2 in plan, and intersects with the roof beam at an angle substantially equal to the inclination angle of the roof.

This intersection is configured as the top joint A. The present invention relates to a joint structure of the diagonal beam 1 at the top joint part A.

The top side end 1c of the diagonal beam 1 is arranged at an inclination angle of the diagonal beam 1 so that the end surfaces of the two diagonal beams 1 are substantially perpendicular when the end surfaces of the two diagonal beams 1 face each other and are connected at a predetermined inclination angle. It is cut at the appropriate angle.

The web 1a at the end IC of the diagonal beam 1 is provided with a plurality of holes parallel to the top end surface of the diagonal beam and spaced at equal intervals to the holes 4d formed in the flange 4b of the cup 1-T4, which will be described later. 1d is formed. This hole 1d is a hole for inserting a bolt 5 when joining the diagonal beam 1. Further, a cut T4 serving as a joining member is formed on a predetermined surface of the web 1a.
