[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a roof panel mounting structure using a roof panel mounting purlin joint according to the present invention will be described below with reference to the drawings.

First, as shown in FIG. 1, a ridge 2 is erected between the upper ends of long pillars 1a located at the center of a plurality of erected pillars 1, and on both sides of the ridge 2. The plurality of purlin joints 3 are fixed at predetermined intervals.

As shown in FIG. 2, the joining piece 3 for a purlin is bent at the same angle as an arrangement angle of a fixing piece 5 having a back plate 4 on a back surface and a roof panel A to be described later at a lower end of the fixing piece 5. The mounting piece 6 includes a mounting piece 6 and a mounting piece 7 projecting from the mounting piece 6 to the fixing piece 5 at the center thereof. A through hole 8 is formed in the fixing piece 5 and the back plate 4. A substantially rectangular hole 9 is provided in a portion of the mounting piece 7 located in front of the through hole 8.
In addition, insertion holes 10 and 11 having different shapes are formed in the upper and lower portions on the front side of the mounting piece 7.

[0014] In a state where the pair of purlin for joining fitting 3 the back plate 4 fitted into the recessed groove 12 formed on both sides of the purlin 2 of purlin for joining shell 3 placed opposite as in FIG. 3, the Purlin
A bolt 15 is inserted into the through hole 8 of the connecting metal fitting 3 and the hole 13 formed in the purlin 2 and a nut 15 is screwed. A plurality of such ridges 3 are fixed to both sides of the ridge 2 at a predetermined interval.

In this case, a substantially rectangular hole 9 is formed in the mounting piece 7 of the purlin joint 3 so that the bolt 14,
Screwing work with nut 15 can be easily performed, also building
Since the back plate 4 of the metal fitting 3 is fitted into the concave groove 12 of the purlin 2, it can be fixed securely and accurately.

Next, at the upper end of the short pillar 1b
The column joint bracket 16 is fixed. As shown in FIG. 4, such a column joint bracket 16 has a leg 17 formed by combining plate members in a cross shape at one end, and a plate-like body 18 is fixed to an upper end of the leg 17, and A joining piece 19 protruding from the upper surface of the plate-like body 18 constitutes the other end of the joint fitting 16 for a pillar , and the tip is formed at the same angle as the arrangement angle of the roof panel A. Become.

Then, as shown in FIG. 5, the leg 17 of the column fitting 16 is inserted into a cross-shaped tenon (not shown) formed diagonally at the upper end of the column 1b. The lower surface of 18 is brought into contact with the upper surface of the column 1b, and the hole 20 and the column fitting
Bolts 22 are inserted through insertion holes 21 formed in the legs 17 of the nuts 16 and nuts 23 are screwed.

Next, a pair of roof panels A is mounted. The roof panel A is provided with a plurality of erection members 25 provided substantially in parallel within a frame member 24 as shown in FIG. A reinforcing diagonal member 35 is bridged between the bridge members 25 via a bridging member 25, and a pair of through holes 26 are formed in the width direction on the upper side of the frame members 24a on both sides, and on the lower side. A pair of through holes 27 are formed in the axial direction.

Then, as shown in FIG. 7, the roof panel A is placed on the mounting piece 6 so that the side face of the upper end corner is in contact with the side face of the mounting piece 7 of the purlin joint 3, and the roof panel A is mounted on the roof panel A. The lower ends of the panels A, A are placed on the plate-like body 18 of the column fitting 16.

Thereafter, the through holes 26 of the roof panels A, A and
The bolts 28 are inserted into the insertion holes 10 and 11 of the purlin joint 3, respectively, and the nuts 29 are screwed together, while the joining pieces of the through-holes 27 of the roof panels A and A and the column joint 16 as shown in FIG. A bolt 31 is inserted into an insertion hole 30 provided in 19 and a nut 32 is screwed. Thereby, a pair of roof panels A, A are joined for purlins.
It is to be installed between the purlin 2 and the pillar 1b via the metal fitting 3 and the pillar joining metal fitting 16.

Similarly, after a plurality of roof panels A are erected, each roof panel A is filled with a heat insulating material or the like as shown in FIG. To complete the series of operations.

As described above, the installation work of the roof panel A is performed as follows.
It is very simple to fix the purlin joint 3 to the purlin 2 and fix the column joint 16 to the column 1b, and then fix the roof panel A to both joints 3,16. A series of roof assembling operations can be greatly simplified without placing a burden on the user, which can greatly contribute to shortening the construction period and reducing costs.

Further, the roof structure obtained therefrom has a sufficient strength against horizontal forces since the roof panel A is erected between the purlin 2 and the pillars 1b, and the torsion of the house, etc. Can be avoided well.

Therefore, there is no need to dispose another member below the roof panel A in order to secure the strength of the roof structure, and there is also an advantage that the internal space can be expanded.

Further , the joining piece 3 for the purlin according to the present embodiment.
Has an advantage that it can be manufactured easily and inexpensively because it has a very simple structure, and is most suitable as a fitting for this type of roof panel A.

Further, the purlin joint 3 may be fixed to the purlin 2 in advance, thereby simplifying on-site work.

Further, if the roof panel A having the diagonal members 35 as in the above embodiment is used, a preferable advantage that the rigidity of the roof structure can be improved is obtained, but such diagonal members 35 are omitted. No problem.

In addition, the specific configuration of the pillar 1b, the purlin 2, etc. can be freely changed in design within the range intended by the present invention.

[0029]

As described above, the present invention is fixed to the side of a purlin so as to bridge the roof panel between the purlin and the pillar.
Purlin for joint device comprises a fixing piece which is fixed to the side surface of the purlin
A mounting piece that is bent at the lower end of the fixing piece and can mount a pair of roof panels on both sides, and a side protruding from the mounting piece to the fixing piece at the center thereof to project the side surface of the roof panel. is composed of a fixable attachment piece, and, together with the fixed piece 該棟trees for joint device through holes are drilled, the portion of the attachment piece which is located in front of the through hole, said purlin since the through hole and the bolt and nut hole for the screwing work makes it easier to be inserted into drilled holes in the purlin to secure the use joint device the purlin is being drilled, the purlin for connecting bracket There is an effect that the screwing work of the bolt and the nut for fixing to the side of the purlin can be performed extremely easily.

Further, on the back of the fixing piece of the joint for purlins ,
Back plate is provided to fit the formed groove in the side of the purlin, yet the through hole, from becoming is formed in the fixing piece and the back plate, the groove of the purlin the backplate purlin for joining fittings an effect that purlin for joint device simply fitted it is possible to reliably and accurately secured to the purlin to.

Further, since the joining metal fitting for purlins according to the present invention has a very simple configuration as described above, there is an effect that it can be manufactured easily and inexpensively.
