Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a joint structure of a metal roof constructed by laying a groove plate such as a color iron plate, and is particularly effective in preventing suga leakage. The present invention relates to a joining structure in which the strength and watertightness of a joining portion between groove plates are increased in a metal roof having a flat roof or a dovetail roof popularized in a snowy area.

[Conventional technology]

Conventionally, on a metal roof in a snowy area, icicles and ice levee formed at the eaves of the roof prevent the snowmelt water from flowing down and move inward from the joint of the grooved material, which is the roof material. Water leakage may occur, and this is generally called suga leakage.

As a roof structure that exerts its power to prevent this suga leakage,
A dewatering yarn is interposed at the joint between adjacent groove plates, and a roll-up structure is used to make the structure flat-roofed, or a rib is provided at the center of the groove plate. Metal roofs such as ant-roofs that have increased the watertightness of their joints have become widespread.

Here, an example of this kind of conventional metal roof will be described with reference to FIGS. 7 and 8. FIG.

Reference numeral 1 denotes a groove plate, and this groove plate 1 is made of a long metal surface material such as a color iron plate, and is provided on one side in the longitudinal direction from an upright rising portion 2, a horizontal portion 3, and a hanging hanging portion 4. The dewatering thread 6 is fixed to the back surface of the horizontal portion 3 with an adhesive 7.

Also, on the other side of the groove plate 1, an upright rising portion 8 and a horizontal engaging portion 9 are formed, and the end of the engaging portion 9 is extended and turned upward, and A folded portion 10 is formed by folding back along the outside, and the end of the folded portion 10 is further bent outward to form a mounting portion.
11 is provided to form a portion to be joined 12.

Then, as shown in the figure, the groove plate 1 connects the mounting portion 11 to the base plate 13.
An underlaying material 14 such as asphalt roofing is interposed therebetween and fixed with fasteners such as nails and screws.

Next, the groove plate 1a to be adjacent to the joined portion 12 of the groove plate 1
Of the joined portion 5a is bent, and the hanging portion 4a of the joined portion 5a is bent to bring the engaging portion 9 of the joined portion 12 into contact. continue,
The abutting engaging portion 9 and the hanging portion 4a are brought into close contact with the horizontal portion 3a. doing.

[Problems to be solved by the invention]

The conventional standing portion 16 is intended to maintain watertightness by interposing the dewatering yarn 6.

However, this dewatering thread 6 is formed of a thread material such as asbestos,
At the time of tightening, there is a case where a defect such as breakage of a thread material and a failure to maintain water tightness occurs.

Further, since the groove plates 1, 1a,... Are metal surface materials such as color iron plates, they are thermally expanded and contracted by a temperature change.

However, the groove plates 1, 1a,.
3 cannot cope with the thermal expansion and contraction, and the adjacent groove plates 1, 1a,.
The standing portion 16 formed between the and the joined portion 12 is damaged, and this causes water leakage.

Further, since the dehydrating thread 6 is attached to the back surface of the horizontal portion 3 of the joining section 5 with the adhesive 7, the dehydrating thread 6 may move when the joining section 5 is fitted into the joined section 12 during construction. As a result, it becomes difficult for the standing portion 16 to be interposed in the center portion to perform the tightening, and there is a disadvantage that the watertightness cannot be maintained.

[Means for solving the problem]

The present invention has been made in view of the above-mentioned drawbacks, and has a strong joint structure between adjacent groove plates constituting a metal roof, and a joint portion capable of allowing thermal expansion and contraction of each groove plate. The object of the present invention is to provide a joint structure of a metal roof created so as to maintain perfect watertightness.

In order to achieve this object, the present invention forms a joint consisting of a rising part, a horizontal part and a hanging part on one side,
A grooved plate made of a metal surface material having a joined portion formed of a rising portion and a horizontal portion on the other side portion, and a flat base end portion having a plurality of horizontally long holes along the longitudinal direction, a rising portion, and a horizontal lock. And a long movable through-hook having a filler such as a caulking material or a sealing material adhered to both or one of the front and rear surfaces of the horizontal locking portion. The movable through hook is continuously interposed with the rising portion and the horizontal locking portion of the movable through hook fixed to the base plate interposed therebetween, and the joint of one groove plate is fitted to the other joined portion, The vertical portion, the horizontal portion, and the horizontal locking portion are integrally bent to form a standing portion.

[Action]

When installing one groove plate on the underlaying material, the rising part and the horizontal part of the joined part formed on the other side are horizontally locked with one side of the rising part of the long movable through hook fixed to the underlaying material. Apply to the underside of the part. Next, the joining portion of the groove plate which is adjacent to the long movable through-hanging member is sandwiched between the joining portions of the groove plate, and the hanging portion of the joining portion is formed as the horizontal portion of the joining portion. After being bent to the side, they are further bent so as to be wrapped together to form a standing portion.

Then, in the standing portion, the filler mounted on the side of the horizontal locking portion of the long movable through-hanger is pinched by the horizontal portion of the joint of the groove plates, and is covered with the joint of each groove plate. In addition to being perfectly maintained in the watertightness between the joints, the joints of the respective groove plates are firmly supported by the long movable through hooks, and the thermal expansion and contraction at the joints is allowed.

The joint of one groove plate is fitted to the joint of the other groove plate, and the bent part is bent so that the hanging part of the joint is integrally wound around the horizontal part of the joint. Therefore, when this standing portion is bent and formed, the filler does not move or break like a conventional dewatering thread. Therefore, the watertightness of the groove plate surface is kept perfect, and it is possible to prevent so-called suga leakage, which is the case where snowmelt water blocked by icicles and ice levee at the roof eaves leaks inside from the junction of the groove plate it can.

Furthermore, since the present invention is provided so that the joint of each groove plate is fixed to the underlaying material using a long movable through-hook, the groove through the movable through-hook supports the temperature change. It can be freely expanded and contracted by heat, so that no excessive force acts on the standing portion, and no damage to the standing portion which causes water leakage occurs. Moreover, since the movable through hook is long, it can be interposed over the entire length of the standing portion, and the supporting strength of the joint portion of the groove plate is further improved. Moreover, since the filler is mounted on both sides or one side of the horizontal locking portion of the movable through hook, the mounting work is easier than the conventional method in which the dewatering thread is fixed to the bottom of the concave portion with an adhesive. In this respect, there is an effect that workability is improved.
