Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to a precast roof structure having roofing boards and the like installed in a factory, and more particularly to a precast roof structure having a drainage gutter part at a connecting portion.

[0002]

[Prior art]

 Conventionally, a unit roof provided with a component part of this kind of drain gutter is disclosed in Japanese Patent Laid-Open No. 3-76962. That is, as shown in FIG. 5, a draining plate 4 composed of a drainage groove portion 2 at a joint end portion of the roof panel 1 and a joint portion 3 projecting upward from a side portion on the joint side of the drainage groove portion 2 is arranged in a joining direction. Make it stick out. At the upper end portion of the joint portion 3, the joint portion 3 is folded back inward and a hook 3a is formed at the tip thereof. When the unit roof is mounted on the support structure 5, the joint portion 3 of the draining plate 4 is formed. When they are arranged opposite to each other, the sealing material 6 is filled between the both joint plates 3 and closed, and then the cap 7 is fitted and fixed by the latch 3a.

[0003]

[Problems to be solved by the invention]

 However, the above-mentioned invention requires considerable skill in the construction of the joint, and there is no problem when the drainage groove 2 is arranged horizontally in the ridge direction. If it is installed in an inclined state, rainwater collected in the drainage groove 2 will enter the inside of the roof panel 1 and a perfect waterproof effect cannot be expected, and the joint end of the upper roof panel 1 There are various problems that it is exposed and impairs the appearance.

[0004]

[Means for solving the problems]

 The present invention has been made to solve the above-mentioned conventional problems, and has a simple structure and easy connection construction, the joint end is not exposed to the outside, and the waterproof effect is complete. The purpose is to provide a precast roof structure with a roofing board on the base plate, and the arabesque section, drain gutter section, and adjacent precast section at the end face of the connecting section. A precast roof structure is characterized in that a rear end of a connecting member including a cap portion that fits over the rain presser of the roof structure is mounted.

[0005]

【Example】

 Hereinafter, the present invention will be described in detail with reference to the embodiments shown in FIGS. 1 is a perspective view of a roof constructed using the precast roof structure according to the present invention, FIG. 2 is an enlarged sectional view taken along the line AA of FIG. 1, FIG. Shows a cross-sectional view of another embodiment.

[0006] In the figure, 10 is a precast roof structure, in which a roof plate 12 is erected on a substrate 11 of a desired shape, which is carried into a construction site and placed on the roof forming portion 13 of the shed. The roof R is constructed by mounting and fixing, and joining from the ridge in the eaves direction.

Reference numeral 14 denotes a plurality of hanging members provided in parallel with the lower surface of the board 11, and serves to reinforce the board 11 and to engage with a locking member 15 projecting from the roof forming portion 13 of the shed. It is for fixing the roof forming portion 13 by positioning them together.

Reference numeral 16 denotes a connecting member, which is attached to the vertical arabesque portion 17 that covers the rear end surface of the precast roof structure 10, a drain gutter 18 having a U-shaped cross section, and the top surface of the tip of the precast roof structure 10 to be connected. The connecting member 16 is fixed at its tip 16a between the base plate 11 and the roofing 21 via a sealing material 22 to form a precast roof structure. It is integrally attached to the rear end of the body 10.

Therefore, the precast roof structure 10 is transferred onto the roof assembly, and the connection member 16 is arranged so as to face the eaves R2 side, and first placed on the roof forming part 13 on the ridge R1 side. Place. Then, when the hanging member 14 mounted on the lower surface is engaged with the locking member 15 mounted on the roof forming portion 13 to perform positioning, the bolt 23 inserted into the common hole of both members 14 and 15 is also inserted. Tighten with the nut 24 to fix.

Next, the roof structure 10 to be joined to the eaves R2 side is arranged so that the rain presser 19 thereof faces the ridge R1 side, and the cap portion 20 of the connecting member 16 is slightly lifted as described above. Position in the same way and fix at this position. Then, by covering the rain cap 19 with the cap part 20 and fixing the cap part 20 to the rain presser 19 with nails or the like, the drainage gutter part 18 of the connecting member is installed below the central part of the joined roof structure 10. It

In the above embodiment, the roof R is constructed by joining the precast roof structure 10 from the ridge R1 side to the eaves R2 side, but as shown in FIG. However, the structure is the same as that of the above embodiment.

[0012]

[Effect of the invention]

 As described above, the precast roof structure according to the present invention has the arabesque part, the drainage gutter part, and the adjacent precast roof structure at the connection end face of the precast roof structure which is constructed by roofing the roof plate on the substrate. Since the rear end of the connecting member consisting of the cap part that fits over the rain presser is attached, the connection work is easy, and the joint end is not exposed to the outside, which makes it look good and the direction of the ridge and the eaves. Even if installed in the direction, there are various effects such as complete waterproofing effect.
