For example, the technique disclosed in Japanese Patent Laid-Open No. 61-109850 (hereinafter referred to as known example 1) has a base having an inclination angle corresponding to the inclination of the roof panel and a locking piece provided at the end. A piece and a mounting piece having an inclined piece having the same inclination as the inclination of the roof panel are respectively fixed to the horizontal members of the frame, and one side edge of the eaves of the roof panel is locked to the locking piece of the base piece, After the roof panel is inverted on the inclined surfaces of the base piece and the mounting piece, the inclined piece of the mounting piece and the roof panel are fixed by bolting. With this configuration, when the roof panel is placed on the frame structure, one side edge of the panel is supported by the locking piece of the base piece, and the roof panel is temporarily received while the roof panel is aligned and laid. It is possible.

Further, Japanese Patent Laid-Open No. 2-256754 (hereinafter, known example 2)
Say. ), The fixed metal object having a roof panel mounting surface inclined to the same slope as the roof slope and a roof panel fixing bolt protruding from the roof panel mounting surface is attached to the frame structure, The fixing bolt is inserted into a fixing hole provided on the lower surface of the roof panel to fix the nut. With such a structure, the roof panel can be positioned and attached by inserting the roof panel fixing bolt into the fixing hole of the roof panel.

Further, Japanese Patent Laid-Open No. 4-182548 (hereinafter, known example 3)

[0007]

However, in each of the above-mentioned conventional techniques, when two vertically adjacent roof panels are fixed to the structure beam, the structure beam or the mounting jig attached to the structure beam is used. On the other hand, a fixing means such as bolts and nuts is required for each roof panel, and there is a problem that the number of members of the fixing means increases and the number of man-hours for fixing work increases.

Further, in the technique of the above-mentioned publicly known example 1, when the mounting piece of the roof mounting bracket is bolted to the upper surface of the horizontal member and the roof panel is bolted to the inclined piece of the roof mounting bracket, the roof mounting bracket is mounted. Since the bolt is tightened in a narrow space formed by the inclined piece and the inclined piece, when the inclination angle of the inclined piece with respect to the mounting piece is small, the tightening space for bolting is narrow and the tightening work is difficult. There is a problem that is.

Further, according to the technique of the known example 2, since the fixing bolts of the fixing hardware are inserted into the fixing holes provided on the lower surface of the roof panel, the fixing holes of the roof panel are fixed when the roof panel is inverted on the fixing hardware. Since it is necessary to drop the roof panel from above while aiming at the fixing bolt of the fixed metal object, there is a problem that it is difficult to position the fixing hole of the roof panel to the fixing bolt of the fixing metal fitting, and the installation work is troublesome.

Further, in the technique of the known example 3, when the fixing piece of the upper bracket is bolted to the upper flange of the upper beam member, the bolt is tightened in a narrow space formed by the receiving piece and the fixing piece. Therefore, when the inclination angle of the receiving piece with respect to the fixing piece is small, there is a problem that the tightening space for bolting is small and the tightening work is difficult.

Further, in the technique of the known example 4, the bolt portion protruding to either the joining plate portion of the first binding material or the receiving plate portion of the second binding material is passed through the other plate portion with a nut. Since it is configured to be tightened, it is necessary to penetrate the bolt portion by aiming at the insertion hole provided on the other plate portion, which makes it difficult to position the bolt portion in the insertion hole and the mounting work is troublesome. There is. Further, since it is necessary to perform the nut tightening work on the side surface of the rafter under the roof panel, there is a problem that the tightening work space is narrow and the tightening work is difficult. Further, since it is necessary to fix the second binding object to the rafters of the roof panel, there are problems that the number of members increases and that the work of attaching the second binding object takes time.

The roof panel and frame structure beam mounting structure according to the present invention fundamentally solves the problems of the above-mentioned conventional example, and it is easy to mount the roof beam structure to the vertically adjacent roof panel beams. Moreover, it is an object of the present invention to provide a mounting structure for a roof panel and a frame beam that can be firmly mounted.

Since the roof panel and the frame structure beam mounting structure according to the present invention has the above-described structure and operation, it is easy to mount the roof panel structure and the roof structure beam which are vertically inclined and adjacent to each other. Moreover, it can be firmly attached.

That is, in the joint structure of the roof panel and the frame beam which are vertically inclined and adjacent to each other, the fixing piece of the lower flange of the mounting jig is brought into contact with the upper surface of the frame beam and is fastened with bolts and nuts. Of the roof jig, which is vertically adjacent to the lower part of the upper flange of the mounting jig in the direction of inclination, is brought into contact with the back surface of the upper end of the roof panel located underneath, and is fixed by tightening bolts and nuts. In addition, the lower surface of the roof panel arranged on the upper side of the vertically adjacent roof panels is brought into contact with the upper portion of the upper flange of the mounting jig, and the upper surface of the lower roof panel is attached. It is constituted by abutting the lower end portion of the upper roof panel and tightening and fixing both roof panels with bolts and nuts.

Therefore, the three independent members (the upper and lower roof panels and the frame beams) can be integrally connected to each other through only the three connecting means (consisting of bolts and nuts) through the mounting jig. Therefore, the number of members used for joining can be reduced, and the number of mounting work steps can be reduced.

Further, in the mounting jig of the first embodiment, the upper end of the upper flange in the slanting direction is positioned in the eaves direction with respect to the vertical axis of the bolt insertion hole provided in the fixing piece of the lower flange. , Even if the roof has a small inclination angle, that is, even if the angle formed by the upper piece in the inclination direction of the upper flange and the fixing piece of the lower flange is small, tightening the bolts and nuts when attaching the mounting jig to the purlin beam The upper flange does not interfere during the work, and the tightening work can be done without problems.

In the mounting jig of the second embodiment, the upper end of the upper flange in the inclination direction and the upper end of the joint piece of the lower flange joined to the upper end in the inclination direction are bolt insertion holes provided in the fixing piece of the lower flange. When the roof is tilted at a small angle, that is, the upper flange and the vertical flange, the height of the pillar piece of the lower flange is set higher than that of the upper flange and Even if the angle formed by the lower flange connecting piece and the lower flange fixing piece is small, the connecting pieces of the upper flange and the lower flange interfere with each other when tightening the bolts and nuts when attaching the mounting jig to the purlin beam. The fastening work can be done without any problems.

Further, since the fixing means including bolts and nuts for fixing the lower roof panel to the mounting jig is arranged below the upper surface of the purlin beam, the bolts and nuts can be used even if the roof inclination angle is small. The tightening work space is secured in a wide angle range, and the tightening work is easy.

Since the roof panel can be inverted and temporarily placed on the upper surface of the upper flange of the mounting jig attached to the purlin beam, the roof panel can be slid and moved on the upper flange in this state. Positioning with respect to the main beam can be easily performed with. Therefore, when the roof panel is inverted on the fixed hardware like the above-mentioned conventional example, it is not necessary to perform a troublesome work such as dropping the roof panel from above while aiming the fixing holes of the roof panel to the fixing bolts of the fixed hardware, Positioning work can be done efficiently.

Further, when fixing the roof panel to the frame beam, it is not necessary to provide a special mounting jig on the roof panel side as in the conventional example, so that the fixing work of the roof panel is simple. Further, since the mounting jig has a simple structure in which two plates are joined (or a reinforcing plate is mounted thereto), it can be manufactured at low cost, and handling such as transportation is easy.
