Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to a new folding board roofing structure of a reform roof in which a new folding board is further roofed on an old old folding board fixed to a tight frame by top bolts.

[0002]

[Prior art]

 When the fold plate roof becomes rusty, it may be peeled off to expose the horizontal members such as the beams and girders below, and the folded plate may be newly replaced on the horizontal member. However, since it takes a lot of labor and cost to dispose of the waste and the waste, the roof is reformed by leaving the folded plate roof as it is and then roofing a new folded plate on it.

Although there are various spraying modes of the old folded plate, when the old folded plate is being roofed, when it is fastened with a nut to a top bolt standing up on the top of the tight frame, the top of the tight folded frame is generally fixed. The bolts are used for the roofing of the new folding plate, but since the top bolts are rusted and the screws are damaged, the nuts are hard to screw into the roofing of the new folding plate, and not only the workability is poor. However, there was a problem that the screwing depth of the nut was uneven and the support of the new folded plate could not be even.

[0004]

[Problems to be solved by the device]

 In view of the above-mentioned circumstances, the present invention provides a new folding board roofing structure for a reform roof in which the old top bolt is repaired by a connecting screw that is screwed into it and the connecting screw can be easily inserted. It was intended.

[0005]

[Means for Solving the Problems]

 In order to achieve the above purpose, the old folding plate that is screwed to the top bolt that stands upright on the top of the tight frame and the top bolt that remains, and use the top bolt to form a new channel-shaped folding plate In the roof of a renovated roof, insert a connecting screw used to fix the new folding plate into the top bolt, and make the connecting screw into a split type with both male and female threads and a slit in the lower half. The present invention provides a new folding board roofing structure for a reformed roof characterized by being formed.

According to the above configuration, even if the top bolt is rusted and already damaged, if the joint screw is rotated, the rust is removed by the slit and discharged to the outside, so screw it into the remaining screw of the top bolt. You can Even if the clues for the first screwing cannot be obtained because the rust has swelled so badly, when the connecting screw is first tapped with a hammer etc., the slit expands and the male and female screws are caught, causing It can be screwed in all the way by being caught.

Various new folding plates can be attached on the basis of the joint screws, but in any case, since the screwing is possible in this way, each joint screw is assumed to be thatched without unevenness. Can be aligned to a uniform height. The following is an example of the manner in which the new folded plate is roofed, which is effective for achieving the purpose.

That is, the base metal for supporting the new folded plate is screwed to the joint screw with the upper and lower nuts, and the base metal is formed into a saddle shape that straddles the top of the old folded plate, and is screwed to the tight frame at the side. If it is stopped, not only can the base metal be fixed uniformly based on the connecting screw, but the new folded plate can be supported stably because it is fixed directly on the top of the old folded plate.

[0009] Furthermore, a supporting metal piece to which new folding plates on both sides adjacent to each other are hooked is screwed on a side portion of the base metal piece, and the supporting metal piece is hooked to a connecting screw or an upper nut screwed into the connecting screw in a stepped shape. When formed, this support metal is also stable, and moreover, a new folding plate can be hung on it for easy roofing.

[Embodiment of the invention]

 Next, an embodiment of the present invention will be described with reference to the drawings.

The drawing shows one embodiment, and in FIG. 1, a channel-shaped new folded plate 3 is put on the corrugated old folded plate 1 and shown.

The old folded plate 1 is mounted on a tight frame 7 which is arranged on the horizontal member 5 of the building by welding or the like, and is tightened with nuts to the top bolts 9 which are erected on the tops of the steps. It was being done. Although the nuts are discarded when the new folded plate 3 is towed, the top bolts 9 are rusted and the screws are difficult to use when tow the new folded plate 3. Therefore, a connecting screw 10 characteristic of the present invention is attached to the top bolt 9.

As shown in FIGS. 2 and 4, the connecting screw 10 has a cylindrical shape having a female screw 10 a and a male screw 10 b, but cannot be screwed into the top bolt 9 as it is. A pair of slits 11, 11 are formed. When the connecting screw 10 was screwed into the top bolt 9, a slight tap was struck with a hammer, so that the remaining screw of the top bolt 9 was caught, and then screwing proceeded. Although the rust was severe, it was scraped off by the slit 11 and discharged to the outside, so it could be screwed in with less resistance.

In addition to the connecting screw 10, a base metal 13 to which the old fold plate 1 is fixed and a support metal 15 attached to the base metal 13 are used for thatching of the new fold plate 3. As a supplement, a spacer 17 interposed between the old folded plate 1 and the new folded plate 3 and a cushioning material 19 are used.

The base metal 13 has a saddle shape straddling the old folded plate 1, has a flat top, and a through hole 21 for the connecting screw 10 is provided at the center thereof. Therefore, when mounting the base metal 13, the ring-shaped (or nut) height adjusting seat 23 is inserted into the top bolt 9, the connecting screw 10 is screwed up to that point, and the lower nut 25 is screwed into this. After inserting, the base metal 13 is fastened to the lower nut 25 with the upper nut 27. Further, the base metal 13 is fastened to the tight frame 7 by the side screw 29 on one side.

The supporting metal piece 15 has a substantially inverted L-shape whose lower base portion is received by the upper nut 27 or the joint 10 exposed on the upper surface thereof, and is fastened to the base metal piece 13 by a screw 31 at the side portion. To be Then, the hooking portion 32 rises from the tip of the base portion, and the hooking portion 32 is formed into a hook shape in which the hook 32 is inverted and bent at the upper end. The left and right new folding plates 3 and 3 are hooked on this.

The new folded plate 3 has a channel shape that spreads downward into the valley of the old folded plate 1 and has a back side that is hooked on the inside of the hook portion 32 while being hooked on the upper nut 27 at the upper end on one side. A stop edge 33 is formed, and a front stop edge 35, which covers the top of the old folding plate 1 and whose front end engages with the stop portion 32, is formed at the upper end on the other side.

The spacer 17 has a substantially V-shape that fits in a valley of the old folded plate 1, and has a back edge 33 of the new folded plate 3 on one end so as to receive the new folded plate 3 as a whole. And a receiving portion 39 for receiving the front stop edge 35 is projectingly provided at the upper end on the other side. As the material of the spacer 17, wood, synthetic resin, or the like is used, and when synthetic resin is used, a reinforcing bar may be inserted by insert molding.

The cushioning material 19 has an inverted trapezoidal shape that fits in the lower half of the valley of the old folded plate 1 and is formed of expanded polystyrene, but it may be filled with urethane foam by in-situ foaming. Since the spacer 17 and the cushioning material 19 are interposed between the old folding plate 1 and the new folding plate 3, not only the fixing of the new folding plate 3 is strengthened but also the heat insulating property and the soundproofing property are improved. Especially, the rain noise is significantly suppressed by the cushioning material 19.

[Effect of the invention]

 As described above, according to the new folding plate roofing structure of the reform roof of the present invention, the old top bolt is repaired or replaced by the connecting screw that is screwed into it, and the new folding plate is based on this. Although it is attached, even if the top bolt is extremely rusted, it is possible to deeply screw in due to the action of shaving the slits, the action of spreading and expanding, the action of discharging rust, etc. Based on the standard, the new folded plate can be stably and nicely shaped, and the workability is also improved, which is an excellent effect.

As a mode of how to roof the new folded plate, when the base metal is used, it is directly mounted on and fixed to the top of the old folded plate, so that the new folded plate can be stably and firmly supported.

In addition, when a supporting metal piece to be used as a base metal piece is used, a new folding plate can be hung on the supporting metal piece for easy roofing.
