Abstract

PURPOSE:To provide the structure of a roof which reduces the cost of production and facilitates the work of erection. CONSTITUTION:The frame of a roof panel 3, at the side of a second floor wall 11, is composed of a channel steel 2 facing outward and a channel steel 3a facing inward, and a horizontal tie-beam member is spanned between a ridge-side roof beam and an eaves-side roof beam, under the clearance between the channels 2, 3a. The lower ends of a knee brace 4 and a post are supported by the horizontal tie-beam member, and the upper ends thereof are respectively inserted into the ridge-side part and the intermediate part of the clearance between the channels 2, 3a and are fastened. In this way, since a truss is composed of these members, a high strength is not required for these members and the cost of production is reduced.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a partial flat roof structure.

[0002]

2. Description of the Related Art Conventionally, as shown in FIGS. 5 and 6, the lower end of a second-floor wall 11, which is a panel material, is supported by a lattice beam 12, and a roof panel 13 on the lower floor is installed from the outdoor surface of the second-floor wall 11. The roof structure in which the attic 14 is formed on the outdoor side of the lattice beam 12 by sticking out the roof panel 13 is provided on the attic 14 with the bundles 15a and 15b and the supporting hardware 16a attached to the upper ends of the bundles 15a and 15b. It was supported by 16b. Both ends of the second floor wall 11 are supported by the pillar 8. The roof panel 3 is formed by attaching a face material 13b to the upper surface of a frame 13a in which a channel steel is framed inward. Bundles 15a, 15b
Is fixed to the upper surface of the roof beam 7 having the lower end protruding to the outdoor side of the lattice beam 12.

[0003]

Conventionally, in this type of roof structure, the load of the roof panel 13 is received only by the bundles 15a and 15b, and when the roof panel 13 is subjected to an external force due to wind or the like, the bundles 15a and 15b are bent. I got a moment. Therefore, the bundles 15a and 15b are required to have high strength, and the production cost is increased.

In addition, when the construction is carried out, first, the bundles 15a, 1
Support metal fittings 16a and 16b are attached to the upper end of 5b, respectively, and the lower ends of the bundles 15a and 15b are fixed to the roof beam 7 by bolting or the like.
The roof panel 13 must be placed on the upper surfaces of the a and 16b, and the roof panel 13 and the supporting metal parts 16a and 16b must be connected to each other using bolts and the like, and the number of steps is large and the construction is complicated.

An object of the present invention is to provide a roof structure which can be easily installed while suppressing production costs.

[0006]

The roof structure of the present invention comprises:
The frame of the second-floor wall of the roof panel near the second-floor wall is composed of an outward groove rope and an inward groove rope that is arranged inside the outward groove rope with a gap, and this outward groove Under the gap between the form rope and the inward groove form rope, a horizontal bridge is erected between the roof beam of the ridge and the roof beam of the eaves, and the horizontal bridge supports the direction and the lower end of the bundle. The upper end was inserted and fixed at the ridge of the gap between the outward grooved steel and the inward grooved steel, and the upper end of the bundle was inserted and fixed in the middle of the gap between the outward grooved steel and the inward grooved steel. It is a thing.

[0007]

According to the roof structure of the present invention, a horizontal member is erected between the ridge girder roof beam and the eaves girder roof beam just below the gap between the outward grooved steel and the inward grooved steel. Support the lower end of the brace and the bundle, and fix the upper end of the bail by inserting it into the ridge between the outward grooved steel and the inward grooved steel, and fix the upper end of the bundle to the outward grooved rope and the inner Since it is inserted and fixed in the middle of the gap of the facing grooved steel, the truss should be composed of the horizontal members, the vertical members of the eaves truss, the bundle, the direction, and the outward facing grooved steel and the inward facing grooved steel. You can

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIGS. 1 to 3, a roof structure according to an embodiment of the present invention comprises a roof panel 3, which is supported by a ridge truss 1 supported by a ridge roof beam 7 and an eaves roof beam 7 '. Thirteen
In support of. The inward groove steel 3a in which the frame of the second wall 11 of the roof panel 3 near the second wall 11 is arranged with a gap between the outward groove steel 2 and the inside of the outward groove steel 2.
And a horizontal bridge member 6 is installed between the ridge roof beam 7 and the eave roof beam 7'under the gap between the outward groove rope 2 and the inward groove rope 3a. The upper ends of the bundles 5 are fixed by inserting them into the ridge and intermediate portions of the gap between the outward grooved steel 2 and the inward grooved steel 3a, respectively.

The horizontal member 6 is connected to the roof beam 7 via roof metal fittings 7a and 7b fixed to the upper surface of the roof beam 7. The ridge truss 1 includes an upper chord member 18a, a lower chord member 18b, and a brace 1
7 and an upward grooved roof panel fixture 1a on the upper surface
Is welded to fix the lower portion to the roof metal fitting 7a of the roof beam 7. The roof panels 3 and 13 are provided so as to project from the outdoor surface of the second floor wall 11. In the roof panel 3, a face material 3b is attached to the upper surfaces of the inward grooved steel 3a and the outward grooved steel 2. The roof panels 13 are arranged side by side with a gap between the adjacent frames 13a, and the upper ends of the canopy 4 and the bundle 5 are located at the ridge and the middle of the gap between the adjacent frames 13a. Each is inserted and fixed.

According to the roof structure constructed as described above, the support 4, the vertical members of the ridge truss 1, the bundle 5, the horizontal members 6,
Inward channel steel 3a and outward channel steel 2 of the roof panel 3
A truss can be constructed by and. Therefore, each member is not required to have high strength as in the conventional case, so that the production cost can be suppressed. Also, the building truss 1,
Frame 4 and bundle 5 are attached to frames 2 and 3a of the floor panel 3, respectively.
Since it is directly fixed to the frame 13a of the floor panel 13 and the joint between the members can be fixed with a single bolt or pin, the construction can be easily performed. In addition,
Other configurations are similar to those of the conventional example.

EFFECTS OF THE INVENTION According to the roof structure of the present invention, a horizontal member is installed between the ridge and roof eaves under the gap between the outward groove steel and the inward groove steel. The bridge supports the lower ends of the brace and the bundle, and the upper ends of the brace are inserted and fixed at the ridge between the outward grooved steel and the inward grooved steel, and the upper end of the bundle is outwardly grooved. And because it is inserted and fixed in the middle of the gap between the inward grooved steel, the truss is composed of the horizontal members, vertical members of the eaves truss, bundles, linings, outward grooved steel and inward grooved steel. can do.

Therefore, unlike the prior art, high strength is not required for each member, and the production cost can be suppressed. In addition, since each ridge truss, each direction and each bundle can be directly fixed to the frame of the roof panel, and the joint between each member can be fixed with a single bolt or pin, the construction can be easily performed.
