の構成材断面を低減することができる。However, in order to provide high rigidity, the roof truss constituting the conventional roof frame is composed of a combination of an upper chord member, a lower chord member, a vertical member, and a diagonal member, and is composed of many constituent members. This would result in an excessive load being applied to the building body on which the roof frame is mounted due to the large number of constituent materials, and would also result in an increase in the cross-section of the constituent materials such as columns and beams in the building body. Not. The present invention aims to reduce the number of constituent materials of the roof frame and the cross section of the building body under conditions that ensure the necessary strength of the roof frame. [Means for Solving the Problems] The present invention provides a roof assembly for a building in which a roof support member is fixed to the upper part of a building body having a beam, and a roof panel is fixed to the upper part of the roof support member. The roof support member is composed of a combination of upper chord members, vertical members, and diagonal members, and is arranged along the beams of the building body. [Function] According to the present invention, by arranging the roof support member along the beam of the building body, the beam can function as a member corresponding to the lower chord of the roof support member. In other words, the roof support member forms a highly rigid truss structure integrally with the beam of the building body, even though it does not include a lower chord member. Therefore, according to the present invention, it is possible to use a roof support member that does not include a lower chord under conditions that ensure the necessary strength of the roof frame, so the number of constituent materials of the roof frame can be reduced. Along with this, it is also possible to reduce the cross section of constituent materials such as columns and beams of the building body. [Example] Fig. 1 is a schematic diagram showing an example of a building to which the present invention is applied;

As shown in FIG. 1, the building 10 has a roof frame 12 formed on the upper part of the building body 11, and a sloped roof is supported on the upper part of the roof frame 12. As shown in FIG. 1, the building body 11 is made up of a plurality of building units 13, and each building unit 13 is made up of a combination of four floor beams 14, columns 15, and ceiling beams 16. In this embodiment, the columns 15 are made of square steel pipes, the beams 14 and 16 are made of section steel, and their respective sections are joined by welding. As shown in FIG. 1, the roof frame 12 includes an eave sill 17 fixed to the upper part of the building body 11, a roof support member 18 for the middle part of the roof, a roof support member 19 for the line, and these eave sills 17. ．．
a roof panel 20 fixed to the top of the lfi root support member 18,19. As shown in FIG. 1, the roof panel 20 consists of two vertical frame members 21 and two horizontal frame members 22. In this embodiment, each of the frame members 21 and 22 is made of section steel and Each village is connected by welding. The eave girder 17 is attached to the building body 1 as shown in FIGS. 1 and 8.
Ceiling beam 1 in building unit 13 located at the needle part of 1
A roof panel support piece 23 is disposed along the top of the roof panel 6 and is joined to the roof panel support piece 23 to which the roof panel 20 is attached. In this embodiment, the eave girder 17 is formed from a section steel, and the eave girder 17 is bolted to the ceiling beam 16. The roof support members 18, 19 are shown in FIGS. 1, 10, and 11.
As shown in the figure, they are arranged along the direction perpendicular to the flow of the pitched roof. Here, the roof support members 18 and 19 are basically approximately the same.
It is a gate-shaped structure, but it changes depending on the length of the corresponding building unit 13. Fig. 2 to Fig. 4 show the roof support member 18 used in correspondence with the building unit 13 with a long girder length, and fjSS Fig. - Fig. 7 show the roof support member 18 used in correspondence with the building unit 13 with a short girder length. The roof support member 18, which represents the roof support member 19, includes an upper chord member 24, two vertical members 25 joined to both ends of the upper chord member 24, an intermediate portion of the upper chord member 24, and a lower end of each vertical member 25. Two diagonal members 26 joined to
It consists of. The roof support member 19 has an upper chord member 27 and two vertical members 28.2, which are substantially similar to those in the roof support member 18.
It consists of wooden diagonal members 29. In this embodiment, the upper chord member 24
．． 27 and vertical members 25.28 are square steel pipes, diagonal members 26.2
9 is formed from section steel, and each of the sections is joined by welding. The roof support member 18.19 includes a base plate 30.31 at the lower end of the vertical member 25.28.
Gusset plate 32.3 at the joint of diagonal member 26.29
3, and a gusset plate 34.35 is provided at the joint between the vertical member 25.28 and the upper chord member 24.27, and the upper chord member 24.
Gusset plate 36 is installed at the joint between 27 and diagonal member 26.29.
．． It is equipped with 37. Further, the roof support member 18 includes a roof panel support piece 38 that is inclined at a specific portion in the longitudinal direction of the upper chord member 24 in accordance with the one-sided direction of the pitched roof. Further, the roof support member 19 includes a pair of roof panel support pieces 39 and 39 that are inclined at specific positions in the longitudinal direction of the upper chord member 27 in correspondence with both flow directions of the pitched roof. In the roof support member 18 , 19 , the interval between the longitudinally adjacent roof panel support pieces 38 , 39 of each top chord member 24 , 27 is set to be the same as the width of the roof panel 20 . Additionally, the roof support member 18.
At 19, each diagonal member 26.29 is joined to a portion (gusset plate 36.37) of the upper chord member 24.27 near the roof panel support piece 38.39. The roof support members 18 and 19 are attached to the beams of the building body 11, that is, the ceiling beams 16 of the building unit 13, as shown in FIGS. The base plates 30 and 31 are arranged so that the vertical members 25 and 28 are located at positions corresponding to the columns 15 of the building body 11, that is, the columns 15 of the building unit 13. Column 15 of the corresponding building unit 13. It is bolted to the ceiling beam 16. Further, the roof panels 20 are arranged such that each of the longitudinal frame members 2
1 to the roof panel support piece 23 of the eave girder 17 (Fig. 8), the roof panel support piece 38 of the roof support member 18 (Fig. 1O),
Roof panel support piece 39 of roof support member 19 (FIG. 11)
are bolted to each. Next, the operation of the above embodiment will be explained. According to the above embodiment, by arranging the roof support members 18.19 along the ceiling beam 16 of the building body 11, the beam 16 can function as a member corresponding to the lower chord of the roof support member 18.19. . In other words, the roof support members 18 and 19 form a highly rigid truss structure integrally with the beams 16 of the building body 11, although they do not include lower chord members. Therefore, according to the above embodiment, the roof support members 18 and 19 without the lower chord can be used under conditions that ensure the necessary strength of the roof frame 12, so the number of constituent materials of the roof frame 12 can be reduced. ,
Along with this, the pillars 15 and beams 14 and 16 of the building body 11
It is also possible to reduce the cross section of constituent materials such as. In addition, in implementing the present invention, the lower end of the diagonal member is not necessarily joined to the lower end of the vertical member, but is attached to the intermediate part between the upper end and the lower end of the vertical member, or to the flexible part of the building body as a member equivalent to the lower chord member mentioned above. It may also be something that is joined. [Effects of the Invention] As described above, according to the present invention, the number of constituent materials of the roof frame can be reduced and the cross section of the constituent materials of the building body can be reduced under conditions that ensure the necessary strength of the roof frame. .
