Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a roof frame that supports roof panels and has a streamlined structure.

[Conventional technology]

In recent years, houses built using the panel construction method, in which walls, W roots, floors, etc. are formed using panel bodies, have been increasingly used not only in non-snowy regions but also in heavy snowy regions.

On the other hand, it is desired that buildings constructed using such panel construction methods have diversified appearances in accordance with the preferences of residents. Therefore, as illustrated in Fig. 14, a so-called partial one-story house, which is easy to manufacture using this construction method, has, for example, a two-story house main body part A with a house attachment part B on a lower floor than the house main body part A. By changing the appearance of the house and improving livability, such a house attachment part B does not change the frame structure of the house main body part A, and is easy to construct. It is desired to form a roof frame well and easily.

However, in houses built using this type of panel construction method,
For example, in the case of a house installed in a snowy area, the roof frame of the house attachment part B installed adjacent to the house body part A has conventionally been connected to the house body part At through the main body part C, as illustrated in FIG. , a connecting beam E is bridged between the attached beam passing through the attached part B of the house, and a roof panel P1 for forming a roof covering the attached part B of the house is connected to the truss beam F provided on the attached beam E. , and were supported by truss beams G arranged in parallel on both sides. Note that a truss beam H near the wall was provided at the base end of the truss beam F on the house main body A side.

[Ll that the invention tries to solve! fi) However,
A roof assembly using such truss beams F and G increases the cost of members. Moreover, in particular, by placing the truss beam F on the joint beam E, the strength at that portion becomes excessive, resulting in excessive quality.

In addition, the joint beam E does not bear the load, but only functions to connect the main body portion C and the attached beam, resulting in an overall increase in cost.

The present invention enables roof panels to be attached using bundles on joint beams, mounting brackets, and truss beams parallel to joint beams, thereby streamlining the roof assembly configuration and reducing costs. The purpose is to provide a roof frame with a new configuration.

[Means to solve the problem]

The present invention relates to a roof assembly of an attached part of a house that is adjacent to a house main body and has a lower rise than the house main body, and which is arranged in the house main body and has pillars erected thereon. , a bundle material in which a connecting beam is spanned between an attached beam of the attached part of the house that is parallel to the main body part, and an inclined roof panel that forms the roof of the attached part of the house is erected on the attached beam; It is supported by a truss beam that is installed parallel to the connecting beam between the mounting bracket arranged on the pillar and the main body and the attached beam, and has diagonal members having the same slope as the roof panel.

[Effect]

A roof panel forming the roof of a house attachment part B adjacent to a house main body part A is supported by bundles, mounting fittings, and truss beams.

In addition, the bundled materials are erected on the spliced beams that span between the main body of the main body part A of the house and the attached beam of the attached part B of the house, so that the load acting on the bundled materials is transferred to the spliced beams. can be transmitted and the connecting beam can be used for load bearing.

Furthermore, since the mounting bracket is fixed to a pillar passing through the main body of the house, the structure of the mounting is simple, and it is also useful for reducing the number of installation steps and costs.

In addition, the truss beam connects the main body and the attached beam, has high bending rigidity, and firmly supports the roof panel. In this way, while effectively using joint beams and pillars of the main body of the house,
Since the roof panels can be attached using bundles, mounting hardware, and truss beams, there are no excessive members, resulting in a roof frame that is inexpensive and has a simple structure.

The joint beam 2 and the beam material 26 forming the frame of the attached part B of the house;
As illustrated in FIG. 9, the attached I-beam 30 has flanges on the upper and lower sides of the web, and has a substantially I-shaped cross section with hanging pieces on both side edges of the lower flange, and is taller than the main body 12. By using a small section steel material and aligning the lower flange with the lower chord member 22 of the main body part 12 in height, the upper flange can be made as small as 1. It is located below the upper surface of the main body part 12.

Furthermore, since the W-root panel Pi P2 has the same slope as in the previous embodiment and is arranged downward as a whole, the side of the M-root panel P2 along the main body A of the house is located above the main body of each beam 26. It is located below the upper surface of 12 and is inclined.

As the bundle material 3, the same one as in the above embodiment is used, and
In the truss beam 6, the lower chord member 49 is located below the outer surface of the main body portion 12, and the column piece 50 is bolted to the mounting surface of the joint member 24. Further, its lower end is supported using a connecting fitting 6e fixed to the mounting surface of the 1881 gluing material 22. Further, on the beam material 2G and the attached beam 30, connection fittings 62, 74, 75, 76 similar to those in the previous embodiment are arranged.

As a result, the structure of the shed Mi1 can be simplified as compared to the conventional structure, the excess product π can be eliminated, costs can be reduced, and the shed assembly has a rational structure, as in the embodiment described above.

In addition, by using only one truss beam 6, the roof assembly of the present invention can also form a W-root roof assembly including only one roof panel P1.

〔Effect of the invention〕

In this way, the roof panel forming the roof attached to the house adjacent to the main body part A of the house is supported by the bundle material, the mounting bracket, and the truss beam, and the bundle material is attached to the main body part of the house main part A. By being erected on a spliced beam that spans between the roof and the attached bundle of the attached part of the house, the load acting on the cough bundle material can be transmitted to the spliced beam, and the spliced beam can be used to bear the load. can be set.

In addition, since the mounting bracket is placed on a pillar that passes through the main body of the house,
Its installation simplifies the configuration by omitting members, and in addition, the truss beam connects the main body and attached bundles, and the diagonal members can support the roof panel. To provide a roof panel that can be firmly attached using bundle materials, mounting fittings, and truss beams while effectively utilizing materials such as the like, and has an inexpensive and easily commercially constructed roof assembly without unnecessary members.
