Description

[Detailed Description of the Invention] The present invention relates to an improvement in the connection structure of folded roof panels.

In the case of the conventional folded roof board connection structure, the first
As shown in the figure and FIG. 2, since the edges of the adjacent folded roof panels 3, 3 were simply overlapped and connected, a stepped portion 13 was formed in the overlapped portion 12. It is. However, since the roof formed by the folded roof sheets 3 is generally constructed with a gentle slope θ, if the amount of rainwater R flowing down the valley increases as shown in FIG. becomes higher than the innermost height of the overlapping portion 12, and the overlapping portion 12
Rainwater backflowed and caused leakage at the joints of the folded roof panels 3. Furthermore, the overlapping parts 12 of the adjacent folded roof panels 3, 3 are fixed with bolts, and both ends of one folded roof panel 3 are positioned and fixed, so that folded roof panels due to temperature changes may occur. There was a problem in that the expansion and contraction of the board 3 was not absorbed, and the folded roof board 3 deformed and deteriorated early.

The present invention was devised in view of the above-mentioned problems, and its purpose is to prevent rain leakage by preventing the formation of stepped portions at the joints of folded roof panels, and to prevent rain leakage between folded roof panels. It is an object of the present invention to provide a connection structure for folded roof panels that can absorb expansion and contraction caused by temperature changes in the folded roof panels at the connecting portions of the folded roof panels.

Hereinafter, the present invention will be explained in detail based on examples. 3
is a folded roof plate made of polycarbonate or the like, and the troughs 1 and peaks 2 are arranged in a direction orthogonal to the waving direction (hereinafter, in the description of the embodiment, the direction orthogonal to the waving direction will be referred to as the front-rear direction). It is long and is constructed with a gentle slope in the front-back direction. Folded roof board 3
A stepped portion 4 is recessed in each of the front and rear edges. Both side surfaces of the stepped portion 4 are set at the same angle as the side surfaces of the valley portion 1. Reference numeral 6 denotes a metal tight frame which is corrugated from side to side, and the shape of the upper surface of the tight frame 6 is approximately the same as the shape of the lower surface of the front and rear edges of the folded roof board 3. As shown in FIG. 7, the tight frame 6 is placed on a beam 5 such as a main building and fixed to the beam 5 at a weld 15. A headless bolt 7 is installed in the center of the bottom surface of each valley 6a of the tight frame 6. A headless bolt 7 is also installed in the center of the top surface of each peak 6b of the tight frame 6. Reference numeral 8 denotes a metal holding fitting, which is composed of a valley holding fitting 8a having a substantially V-shaped cross section and a peak holding fitting 8b having a substantially V-shaped cross section. The shape of the lower surface of the trough holding fitting 8a is approximately the same as the top surface shape of the trough 1 including the step 4 at the edge of the folded roof board 3, and the length of the trough holding fitting 8a in the front and rear direction is The length is approximately twice the length of the stepped portion 4 of the folded roof plate 3 in the front-rear direction. A bolt hole 9 is bored in the center of the bottom plate portion 11 of the valley holding fitting 8a. Mountain part presser fitting 8b
The lower surface shape is approximately the same as the upper surface shape of the peak part 2 of the folded roof plate 3, and the top plate part 1 of the peak part holding fitting 8b
A bolt hole 9 is bored in the center of 6. Third
The figures to FIG. 5 show the construction state in which the folded roof panels 3 are connected, and the front half of each opposing edge of the folded roof panels 3 adjacent to each other in the front-rear direction is separated by the bolt 7 of the tight frame 6. and are listed in the latter half. The first half and the second half of the valley holding fittings 8a are respectively placed on the valley portions 1 including the step portions 4 of the opposing edges of the folded roof sheet 3, and the bolts 7 are inserted into the bolt holes 9. The bottom plate part 11 of the valley holding metal fitting 8a is placed within each step 4 of each edge of the folded roof board 3, and the bottom surface of the valley part 1 excluding the top surface of the bottom plate part 11 and the edge of the folded roof board 3 is There is one side to the other. The first half and the second half of the peak holding metal fittings 8b are respectively placed on the peaks 2 of the opposing edges of the folded roof board 3, and the bolts 7 are inserted into the bolt holes 9. And Boruto 7 and Natsu 10
By screwing and tightening, the opposing edges of the adjacent folded roof panels 3 are clamped between the tight frame 6 and the holding metal fittings 8. Further, a packing 17 made of butyl rubber or the like is interposed between the tight frame 6 and the folded roof sheet 3, and a packing 18 made of butyl rubber or the like is also inserted between the holding metal fitting 8 and the folded roof sheet 3. This allows the folded roof panels 3 to be connected in a watertight manner. Reference numeral 19 denotes a caulking material filled in the joint between the valley holding fitting 8a and the peak holding fitting 8b, and 20 indicates the bottom plate portion 11 of the valley holding fitting 8a, the side surface of the packing 18, and the stepped portion 4 of the folded roof plate 3. This is a caulking material that fills the gap between the sides of the However, the valley presser metal fitting 8a
The upper surface of each opposing end edge of the folded roof sheets 3 adjacent in the front-rear direction (that is, the direction orthogonal to the waving direction) is covered over the entire length in the waving direction by the wavy holding metal fitting 8 consisting of The connecting portion is thus made waterproof by covering the entire length of the connecting portion in the corrugating direction with the corrugated presser fitting 8. FIG. 9 shows the construction state of the roof 21, in which folded roof plates 3 are installed on a roof frame 23 formed by combining beams 5 supported by pillars 22.

As described above, in this invention, the bottom plate part of the corrugated holding metal fitting is housed within each step of adjacent folded roofing plates, and the upper surface of the holding fitting and the upper surface of the trough of the folding plated roofing plate are flush with each other. There is no unevenness formed at the connection between the valleys of the folded roof panels, and therefore rainwater flowing down the valleys of the folded roof panels flows smoothly and backflows through the overlapping portions and flows into the building from the connection surface. This has the advantage of preventing infiltration. Bolts are installed upward from the center of the valley bottom of the corrugated tight frame placed on the beam material, and each opposing end of the folded roof panels adjacent to each other in the direction orthogonal to the waving direction is installed on the tight frame. Place the edges with the bolts as boundaries,
A corrugated holding metal fitting is used to cover the upper surface of each opposing edge of the folded roofing plate adjacent in a direction perpendicular to the waving direction of the folded roofing plate over the entire length in the waving direction, and a tight frame is inserted into the bolt hole of this holding fitting. The bolts were inserted and nuts were tightened, and the opposing edges of the folded roof panels adjacent to each other in the direction perpendicular to the waving direction were sandwiched between the tight frame and the holding metal fittings in a watertight manner. It can be shifted in the direction perpendicular to the waving direction while being held between the tight frame and the holding metal fittings without being restricted by the bolts.
Therefore, expansion and contraction due to changes in temperature of the folded roof panel itself can be absorbed by the connecting portion, and there is an advantage that the folded roof panel does not deform and deteriorate early.
