Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for supporting a roof of a house, and more particularly to a structure for supporting a roof applied to a steel house.

[0002]

2. Description of the Related Art Recently, interest in so-called steel housing as a type of imported housing has been rapidly increasing. In this steel house, a wall framework and an opening framework are manufactured by using steel (galvanized steel sheet) having a thickness of about 1 mm, and these are combined to construct an outer wall and an inner wall.

FIG. 4 schematically shows an example of a roof support structure in a conventional steel house. In this steel house, both mountain-shaped floating roofs with the ridge M as the apex are supported, and on top of two walls 21 and 21 arranged to face each other (opposite in the depth direction in the drawing). A single ridge beam (roof beam) 32 is hung over a steel ridge material (bundle) 31 provided on each of the roofs, and a roof ridge formed by two roofs 13 on the ridge beam 32. The parts M are facing each other. That is, the ridge portion M of the two-story roof formed by the two roofs 13 is
It is supported by a steel building material 31.

In such a steel house, walls,
If a common panel such as a roof is prepared and then this panel is assembled on site to construct a wall or roof, workability on site will be improved.

[0005]

However, the conventional roof support structure has the following various problems.

(1) First, it has been difficult to form the roof into a panel for the following reasons.

(1-A) If the panel is made in advance, the mounting work from the roof (that is, the roof panel and the roof panel,
It is necessary to remove the face plate of the roof panel in the work of joining the roof panel and the master beam. For this reason, it is not possible to save labor in the field work, and unstable work is required on a sloped roof, resulting in poor work efficiency and safety. Further, (1-B) when attempting to perform the mounting work from the lower side of the roof, the ridge beam 32 becomes an obstacle and the working space for the roof is small, so that it is difficult to perform complete joining. Furthermore, there is a risk of slipping when installing the roof panel due to the slope of the (1-C) roof. In addition, under such a load that the roof panel is about to shift, it is difficult to adjust the set, and the roof panel is likely to be defectively attached. (1-D) If a scaffold for mounting is assembled to perform the mounting work from the lower side of the roof,
The assembling work must be stopped while the scaffold is assembled, and further, after the assembling, the scaffold becomes an obstacle in the subsequent work.

(2) Second, in the conventional roof support structure, the building material 31 facing the center of the end wall 33 is structurally important.
However, there is a problem in that it is not possible to form the openings (windows, ventilation openings) 33a as shown by the chain double-dashed line in FIG.

(3) Third, conventionally, since the end wall 33 is treated integrally with the wall 21 and has an irregular shape, there is a problem that it is difficult to make it common as a panel.

(4) Fourth, as the roof becomes steeper, the horizontal rigidity of the roof surface becomes weaker, making it difficult to obtain a stable structure.

The present invention has been made in view of the above problems, and an object thereof is to make it possible to form a roof panel and to form an opening in the end wall and to perform work during assembly. The purpose is to provide a structurally stable roof support structure with good performance.
