2. Description of the Related Art Conventionally, a roof of a building has been constructed by setting a base plate on a rafter at a construction site and then laying a roof plate on the roof through a roofing. Japanese Patent Application Laid-Open No. 3-84153 discloses a construction in which a unit roof manufactured in a factory is transported to a construction site and the roof is constructed by joining the unit roof in order to shorten the construction process.

[0003] That is, this unit type roof panel,
As shown in FIG. 4, a roof panel P in which plywood 2, roofing material 3, and plate-like roofing material 4 are laminated on a core material 1, is connected between each plate-like roofing material 4 and roofing material 3. With a lower edge having a longitudinal projection 5a of the joint drainer 5 formed in a U-shape interposed therebetween, a flat mountain-shaped upper end of the joint drainer 5 of each roof panel P is formed at each end of the roof drain P. When the joint drainer 6 is covered with the joint drainer cover 6 having the joint drainer 6a, the locking part 6a of the drainer cover 6 is engaged with the locking part 5b at the upper edge of each joint drainer 5.

[0004]

[Problems to be Solved by the Invention]
In the invention disclosed in Japanese Patent Application Laid-Open No. 84153/1990, the longitudinal protrusion 5a of the joint drainer 5 is provided with a roofing material 4
Therefore, the roofing material 4 at the connection portion of the roof panel P needs to be a semi-finished unit type roof panel floating from the roof panel P. Therefore, while there are problems in terms of quality control and the like, there are various problems that the on-site construction requires time and considerable skill.

SUMMARY OF THE INVENTION The present invention has been made to solve the conventional problems as described above, and a roof can be constructed by joining a precast roof structure as it is. The object of the present invention is to provide an easy connection construction, and the gist of the invention is to form a H-shape by fixing side wall members to both side edges of a rectangular substrate, respectively. A plurality of reinforcing members are provided between the side wall members in a direction orthogonal to the side wall members on the lower surface, and a precast roof structure having a roof plate is mounted on the upper surface via roofing. The structure and the outer surfaces of the side wall members are respectively faced to each other and disposed on the roof forming portion of the hut group, and the locking member provided on the roof forming portion and the reinforcing member are precast by fastening bolts and nuts. roof When fixing the adult ゝ monitor, an upper surface of the both side wall members covered by the extended portion of the roofing,
Further, there is provided a connection structure for a precast roof structure, wherein the upper surface thereof is fitted with a cap.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to an embodiment shown in FIGS. 1 to 3. In the drawings, reference numeral 10 denotes a precast roof structure, which is a long rectangular substrate 11; The side walls 12 and 12 are fixed to both side end surfaces to form an H-shape. A roof plate 14 laid on the upper surface of the substrate 11 via a roofing 13 is provided.
The precast roof structure 10 comprises a plurality of reinforcing members 15 mounted on the lower surface of the substrate 11 between the side wall members 12 and 12 in parallel with the orthogonal direction.
Are previously manufactured in a factory.

Reference numeral 16 denotes a roof forming part of the roof set, which is a purlin or a rafter, and 17 denotes an L-shaped locking member attached to the roof forming part 16. In the figure, reference numeral 18 denotes a sealing material, and 19 denotes a decorative cap. This decorative cap includes a top surface portion 19a, left and right side wall portions 19b, and a horizontal portion 19c horizontally connected outward from a lower end of the side wall portion 19b. And a folded piece 19d formed at the end thereof.

Thus, the precast roof structure 10 having the above-described structure is placed on the roof forming section 16 of the roof set in parallel from the ridge in the eaves direction, and the reinforcing members 15 attached to the respective lower surfaces are attached to the roof forming section 16. The upper locking member 17 is engaged. In this case, the side wall member 1 provided on the precast roof structure 10
2 and the outer surface of the side wall member 12 of the roof structure 10 joined thereto are positioned so that they face each other, and in this state, the reinforcing member 15 and the locking member 17 are inserted through the common hole in the bolt 20. With a nut 21.

The roofing 1 extending from the rising end of the roofing plate 14 of the precast roof structure 10
3 on the side wall member 12 of the roof structure 10 which connects the first and second roof members 3 with each other.
After filling, the roof structure 10 is connected by fitting and fixing the decorative cap 19 to this joint, and the above-described operation is repeated to complete the roof. In addition, even if the said roof plate 14 is a single plate, a plurality of flat plates are made by one letter,
It may be formed in a diamond shape or the like.

[0010]

As described above, the connection structure of the precast roof structure according to the present invention is such that the side wall members are fixed to both side ends of the rectangular substrate to form an H-shape, respectively. A plurality of reinforcing members are provided between the side wall members on the lower surface in a direction perpendicular to the side wall members, and a precast roof structure having a configuration in which a roof plate is mounted on the upper surface via roofing,
The precast roof structure connected thereto and the outer surfaces of the side wall members are respectively placed on the roof forming portion of the hut assembly so as to face each other, and the locking member provided on the roof forming portion and the reinforcing member are bolted together. Each of the precast roof components is fixed by fastening nuts, and at the same time, the upper surfaces of the side wall members are covered with the extension of the roofing, and the upper surfaces are further fitted with caps. Has a large structural strength and improves durability. In addition, it is easy to fix the roof components to the roof formation part and to join the roof components together easily, and it is possible to reliably maintain the waterproofness of the joints. There are various effects such as that the object can be obtained.
