[0002]

2. Description of the Related Art Recently, a building having a steel frame structure and an outer wall made of a panel material such as an ALC panel has been constructed. Among such buildings, there is one in which the roof structure is a gable roof and a cross-roof consisting of a large roof and a small roof.

In the above-mentioned cross-ridge roof, the gable wall is formed between the diagonal beam on the large roof side and the horizontal beam.
There was a problem that the attic space of the large roof and the small roof could not be used effectively. The applicant of the present invention has developed a cross-beam to solve the above problems and has already applied for a patent (Japanese Patent Application No. 3-191165). The cross-beams according to the invention are advantageous in constructing cross-roofs in which one roof on the small roof side and one roof on the large roof are in the same plane.

[0004]

However, in the crossbeams according to the above invention, as shown in FIG. 6, the roofs 51a and 51b that form the large roof 51 and the roofs 52a and 52b that form the small roof 52 are When making a completely different plane, that is, the master beam 53 of the small roof 52
In the case where the structure is connected to the gable wall 56 independently of the master beam 54 and the slanted beam 55 of the large roof 51, the connecting part 58 between the cross-beams 57
In addition, it is necessary to form a joint 59 between the cross-beam 57 and the diagonal beam 55 on the side of the large roof 51, and a problem arises that different components are required for each of these joints 58 and 59. .

Further, as shown in the figure, a part of the ridge beam 57 projects to the end wall 56 and is arranged in parallel with the end wall 56, which may interfere with the panel forming the end wall 56. The problem arises.

An object of the present invention is to further develop the above invention to provide an effective use of the attic space and to provide a cross-beam that does not increase the number of parts and does not interfere with the end wall. is there.

[0007]

In order to solve the above-mentioned problems, a cross-beam according to the present invention is a cross-beam that is arranged in a cross-section of a gable roof, and is a gable forming a gable wall. Supporting metal fittings for supporting the panel are attached at a predetermined pitch, and one end is fixed to a lower side building beam independent of the higher side building beam.

[0008]

[Advantage] According to the above-mentioned cross-beam, the two-direction structure that configures the roof (the large roof) on the high side in the cross-section without increasing the number of types of parts while effectively utilizing the attic space Even if the roof and the roof in the lower direction (small roof) form a different plane,
The cross-beam does not interfere with the wife wall.

That is, one end of a cross-beam that is constructed by attaching support brackets for supporting the gable panel at a predetermined pitch is used as a main-beam of a small roof provided separately from the main-roof of the large roof in the cross-ridge. Since it is fixed, it is possible to support the small roof and the corresponding gable panel in the different building by the different building beams.
Therefore, the attic of the large roof and the attic of the small roof can be communicated with each other, and the attic space can be effectively used.

As described above, since one end of the cross-beam is fixed to the one with a small roof, the cross-beam is not a common wall even if the large roof and the small roof do not share the same plane. Does not project to the side. Therefore, the cross-beam does not interfere with the gable panel forming the gable wall.

[Embodiment] An embodiment of the cross-beam will be described below with reference to the drawings. Fig. 1 is a front view of a cross-beam, and Fig. 2 is Fig. 1.
II-II sectional view of Fig. 3, Fig. 3 is a schematic diagram for explaining the mounting structure of the cross-beams in the cross-section, (a) is a perspective view, (b)
FIG. 4 is a front view, FIG. 4 is a view for explaining an example of an assembly structure of a cross-beam and a roof of a small roof, and FIG. 5 is a cross-sectional view for explaining a mounting structure of a gable panel.

First, referring to FIGS. 3 (a) and 3 (b), a schematic structure of a ridged portion constructed by using the ridged beam 1 according to this embodiment will be described. The cross-beams 1 having supporting members 2 provided at predetermined intervals are fixed at their upper ends to the main beams 4 forming the small roof 3, and the lower ends are directly or at the height of the eaves of the small roof 3. Is fixed to the horizontal beam 5 of the small roof 3 via a connecting member corresponding to.

The cross-beam 1 is a slanted beam 6 which constitutes a small roof 3.
Has a length substantially equal to that of the diagonal beam 6 and is arranged at a level substantially equal to the arrangement level of the diagonal beam 6. In addition, ridge bridge 1
When both ends of the cross beam are fixed to the ridge beam 4 and the horizontal beam 5, the cross beam 1 is located below the diagonal beam 8 forming the large roof 7. A plurality of gable panels 10 are attached to a surface of the large roof 7, which is composed of the diagonal beam 8 and the cross-beam 1 and the horizontal beam 9 on the side of the large roof 7 to form a gable wall 11.

As shown in FIG. 1 and FIG.
A pitch corresponding to the width dimension of the end panel 10 on a web of a member made of a channel steel having a U-shaped cross section such as a channel steel or a C-shaped steel having a length substantially equal to the length of the diagonal beam 6 of the small roof 3. The supporting member 2 having a L-shaped cross section is arranged, and the supporting members 2 are fixed by welding or the like. Further, bolt holes 1a for connecting to the main beam 4 of the small roof 3 or the horizontal beam 5 are formed at both ends of the cross-beam 1.

The upper end of the cross-beam 1 is fixed to the cross-beam 4 of the small roof 3. In this embodiment, as shown in FIG. 4, an angled bracket 12 is fixed to the end of the ridge beam 4, and the bracket 12 and the ridge beam 1 are connected via a connection plate 13. However, the fixing structure of the cross-beam 1 to the cross-beam 4 is not limited to the above-mentioned structure, a T-shaped bracket may be used, and the cross-beam 1 may be formed without the connection plate 13. And the bracket 12 may be directly connected.

The lower end of the cross beam 1 is fixed to the horizontal beam 5 of the small roof 3 directly or through a connecting member (not shown). The fixing structure of the cross-beams 1 to the horizontal beams 5 is variously set according to the eave height of the small roof 3. For example, small roof 3
When the eaves are tall, a box-shaped stand serving as a connecting member having a height corresponding to the eaves height of the small roof 3 is fixed to the horizontal beam 5 in advance, and an L-shaped or T-shaped bracket is attached to the stand. It is fixed, and the lower end of the ridge bridge 1 is fixed to the bracket. When the eave height of the small roof 3 is low, the bracket is fixed to the horizontal beam 5, and the lower end of the ridge difference 1 is fixed to the bracket.

The support member 2 is for mounting and supporting a mounting bracket 14 (see FIG. 5) on which the lower end of the end panel 10 is placed. For this reason, the support member 2 has a protruding piece 2a formed with a size larger than the thickness of the end panel 10 and a protruding piece 2a.
It is formed by a support piece 2b that is formed into an L-shape at the tip of a. The length of the protruding piece 2a and the length of the supporting piece 2b (the length in the left-right direction in FIG. 1) are the same even when the end wall 11 is formed by the end panel 10 having different width dimensions. Have a size capable of supporting the gable panel 10 in common. That is, for example, when the end panel 10 having a width of 305 mm is used, each end support member 2 is configured to support the end panel 10, and the end panel 10 having a width of 610 mm, for example.
Is used, it can be supported by every other supporting member 2.

The mounting angle of the support member 2 in the cross beam 1 is approximately the same as the inclination of the diagonal beam 6 so that the support member 2 becomes horizontal when the cross beam 1 is attached to the cross beam 4 and the horizontal beam 5. Set to equal angles.

Next, the structure for supporting the gable panel 10 which constitutes the gable wall 11 using the ridge beam 1 constructed as described above will be explained with reference to FIG. The cross-beam 1 is arranged along the slanted beam 6 of the small roof 3, the upper end is fixed to the main beam 4 of the small roof 3, and the lower end is fixed to the horizontal beam 5. An angled fixing member 15 for fixing the upper end side of the gable panel 10 is attached to the diagonal beam 8 of the large roof 7 on the side of the small roof 3 along the beam 8.

Main beam 4 of small roof 3 and horizontal beam 5
When the fixing member 15 is attached to the diagonal beam 8 of the large roof 7 and the fixing member 15 is fixed to the diagonal beam 8 of the large roof 7, the supporting piece 2b of the supporting member 2 and the fixing piece 15a of the fixing member 15 in the cross beam 1 are in the same plane in the vertical direction. The support piece 2b of the support member 2 arranged above is in a horizontal state. At this time, the protruding piece 2a of the support member 2 does not need to be horizontal. However, it is preferable that the protruding piece 2a is also horizontal in order to avoid interference with other members.

Next, the gable panel 10 having a predetermined size and shape is fixed to the cross beam 1 and the fixing member 15. As for the method of fixing the gable panel 10, the mounting bracket 14 is hooked on the support piece 2b of the supporting member 2 in the cross beam 1 in advance, and the gable panel 10 to which the bolt 16 is mounted is placed on the mounting bracket 14 in advance. The bolts 16 attached to the panel 10 are made to face the holes formed in the fixing pieces 15a of the fixing member 15 and the mounting member 14, respectively, and the nuts 17 are screwed into the bolts 16.

As described above, the plurality of gable panels 10 are sequentially fixed to the cross-beams 1 and the fixing members 7 to form the gable wall 11 in the cross-ridge portion.

[0023]

As described above in detail, in the cross beam according to the present invention, the supporting member for supporting the gable panel is attached at a predetermined pitch, and one end is fixed and attached to the ridge beam constituting the small roof. Therefore, the lower end of the gable panel can be supported and fixed by the support member of the cross beam.
Therefore, the gable wall is configured between the diagonal beam of the small roof and the diagonal beam of the large roof, and the attic space of the small roof and the attic of the large roof can be communicated with each other to effectively use the attic space.

Further, the size and shape of the gable panel are the same in the part where the large roof diagonal beam and the ridge beam are parallel to each other, so that the number of gable panels can be reduced. Moreover, since the cross-beam does not become longer than the diagonal beam of the small roof, part of the cross-beam does not project to the gable wall. For this reason, when the gable panel is attached to the gable wall, the gable panel and the cross-beam do not interfere with each other.

Since the ridge beam according to the present invention is always fixed to the ridge beam of the small roof at the upper end, it is possible to join the ridge beam and the ridge beam with the same component, regardless of the ridge structure. . Therefore, regardless of the structure of the different building, the parts can be shared and rationalized.
