Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a roof structure which is prefabricated in a factory, that is, a precast roof structure in which a roof plate is installed on a substrate is joined at a construction site to construct a roof having a predetermined area. Regarding connection structure.

[0002]

[Prior art]

 In the past, building a roof for a building was done by placing a base plate on the rafters at the construction site, and then roofing the roof plate through the roofing. Japanese Patent Laid-Open No. 3-84153 discloses a unit roof manufactured in a factory, which is brought into a construction site and is joined to the roof in order to shorten the length. That is, as shown in FIG. 4, this unit type roof panel is a roof panel P in which a plywood 2, a roofing material 3, and a plate-like roofing material 4 are laminated on a core material 1, and the connecting method is each plate-like roof. A lower edge portion having a longitudinal projection 5a of a joint drainer 5 formed in a U-shape is interposed between the roofing member 4 and the roofing member 3, and a flat mountain shape is formed on the opposing joint drainer 5 of each roof panel P 1. When the joint drainer cover 6 having the U-shaped locking portions 6a at both ends thereof is covered, the locking portion 6a of the draining cover 6 is attached to the locking portion 5b at the upper edge end of each joint drainer 5. It is configured to be engaged.

[0003]

[Problems to be solved by the device]

 However, the invention disclosed in the above-mentioned Japanese Patent Laid-Open No. 3-84153 has a structure in which the longitudinal projection 5a of the joint drainer 5 is inserted into the lower surface of the roofing material 4, so that the connecting portion of the roof panel P is connected. It is necessary that the roofing material 4 in Fig. 2 is a semi-finished unit type roof panel that is floated from the roof panel P. Therefore, there are problems in quality control and other problems, and on-site construction requires time and skill.

[0004]

[Means for solving problems]

 The present invention has been made to solve the above-mentioned conventional problems, and the roof can be constructed by joining the precast roof structural bodies as it is, and the connection construction is easy. The purpose of the present invention is to provide a plurality of reinforcing members in the direction orthogonal to the side wall members on the lower surface of the substrate having the side wall members fixed to both side ends. , A precast roof structure having a roofing board on the upper surface, and the precast roof structure connected to the roof structure and the outer side surface of the side wall member are brought into face-to-face contact with each other, and the precast roof structure is arranged in the roof forming part of the rooftop assembly. Connection of the precast roof structure characterized in that the reinforcing members are engaged with the locking members provided in the roof forming part to fix each precast roof structure, and the both side wall members are fitted with the decorative caps. Construction A.

[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 by 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, and FIG. 3 is an enlarged perspective view of a main part of FIG. Indicates.

In the figure, 10 is a precast roof structure, which is a long base plate 11, side wall members 12 attached to both end surfaces of the base plate 11, and a roof that is installed on the top surface of the base plate 11 through a roofing 13. It is composed of a plate 14 and a plurality of reinforcing members 15 mounted on the lower surface of the substrate 11 in parallel with the width direction thereof. The precast roof structure 10 is manufactured in advance in a factory.

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

Thus, the precast roof structure 10 having the above-mentioned structure is placed on the roof forming part 16 of the roof set in parallel from the ridge to the eaves direction, and the reinforcing members 15 attached to the respective lower surfaces of the roof forming part 16 are attached. Engage with the upper locking member 17. In this case, the outer side surface of the side wall member 12 provided on the precast roof structure 10 and the outer side surface of the side wall member 12 of the roof structure 10 to be joined with the side wall member 12 are positioned so as to be in contact with each other. The bolt 20 having the locking member 17 inserted through the common hole thereof is tightened with the nut 21.

Then, when the roof members 10 of the roof structure 10 connecting the roofing members 13 extending from the rising end portions of the roof plates 14 of the precast roof structure 10 are crossed with each other and covered, After filling the gap with the sealing material 18, the decorative cap 19 is fitted and fixed to the joint portion to connect the roof structure 10, and the roof is completed by repeating the above-described work. The roof plate 14 may be a single plate or a plurality of flat plates formed into a single character, a diamond shape, or the like.

[0010]

[Effect of device]

 As described above, the connection structure of the precast roof structure according to the present invention is such that when a plurality of reinforcing members are attached in the direction orthogonal to the side wall members on the lower surface of the substrate having the side wall members fixed to both side ends. In addition, a precast roof structure with a roofing board on the upper surface is placed in the roof forming part of the rooftop assembly by interfacing the precast roof structure connecting with this and the outer surface of the side wall member with each other. When the precast roof structure is fixed by engaging the above-mentioned reinforcing member with the locking member provided in the roof forming portion, the both side wall members are fitted with the decorative caps. There are various effects that it is easy to attach the body to the roof forming part and to join the roof constituents together, and the characteristics of precast can be effectively exhibited.
