Description

[Detailed Description of the Invention] This invention relates to a mounting structure for attaching a metal plate for a roof, a metal plate for walls, or other metal plates to a purlin, a rim, or other supporting member.

Conventionally, the joint and attachment structure of metal plates for roof walls has been as follows: (1) As shown in Figs. A structure in which the metal plate 6 is fixed to the purlin 8 or the rim 9 by a hook bolt 7 passing through it; (2) A square wave-shaped installation on the purlin 8 or the rim 9 as shown in FIGS. 4 and 5. The corrugated bottom part of the metal fitting 10 is fixed by bolts 11 or welding, and the rectangular corrugated metal plate 12 is fitted to the mounting fitting 10, and the ends of the metal plates 12 in the wave crest direction are overlapped and spliced to each other. A structure in which the metal plate 12 is fixed to the mounting bracket 10 by bolts 13 that are fixed to the crest of the mounting bracket 10 and penetrated through the crest of the metal plate 12, (3
) As shown in FIGS. 6 and 7, a metal plate 15 having rising plates 14 on both sides and a groove-shaped hanger 16 interposed between adjacent metal plates 15 are placed on the main building 8, The middle part of the hanger 16 is fixed to the main house 8 with a bolt 11, and the arms of the hanger 16 are wrapped around the adjacent rising plates 14, the cap 17 with a grooved cross section interposed therebetween, and the arms of the hanger 16. Structure, (4) As shown in FIG. 8, a structure in which a heat insulating panel 20 consisting of a heat insulating layer 1B and metal plates 19 integrally laminated on both sides of the heat insulating panel 20 is fixed to the rim 9 with bolts 11 passing through it. etc. are generally adopted.

However, in the case of conventional board joints, it is moisture-proof.

In the case of the conventional mounting structure, since it is necessary to provide a through hole in the metal plate, there is a problem that the airtightness is insufficient, and the waterproofness, moistureproofness, and airtightness are low.

Furthermore, recently, it has been proposed to provide complete waterproofing, moisture-proofing, and airtightness to the plate joints by continuously joining metal plates such as stainless steel plates or steel plates by seam welding at a construction site.

However, as mentioned above, in order to attach the metal plate, holes must be made in the metal plate, so there is a problem that the effects of waterproofing, moisture proofing, and airtightness that have been painstakingly provided are not utilized.

This invention provides a metal plate mounting structure that allows metal plates to be stably and firmly attached to purlins, rims, and other members without performing any processing on the metal plates that would cause a reduction in waterproof, moisture-proof, or airtightness. The purpose is to

Next, this invention will be explained in detail using illustrated examples.

9 to 11 show a first embodiment of this invention, in which a row of continuously extending mounting protrusions 3 are bent and formed at the joints of adjacent metal plates 1. Its ridge 3
is a pair of protrusion constituent plates 2 that are in contact with each other over the entire length.
The intermediate portion of the protrusion is continuously welded in the longitudinal direction by seam welding 21 or the like.

A plurality of through holes 22 are provided on the tip side of the protrusion 3, and support members 5 made of lightweight channel steel are provided on both sides of the protrusion 3.
The web of the support member 5 is brought into contact with the metal plate 1, and the web of the support member 5 is provided with a through hole 23 that matches the through hole 22. The bolt 4 inserted through the through hole 23 and the through hole 22 of the protrusion 3 connects the protrusion 3 to each support member 5 by tightening.

FIG. 12 shows a second embodiment of this invention,
Although the support member 5 is provided only on one side of the protrusion 3, the other structure is the same as that of the first embodiment.

The support member 5 can be used as a rim or a purlin of a building.

Further, when the support member 5 is used as a fitting for attaching to a rim or a purlin, a short support member 5 may be used.

The through hole for bolt insertion in the protrusion 3 is formed by sheet welding 2.
It may be an elongated hole extending in the longitudinal direction of the bolt, or it may be a round hole having a diameter such that a gap is created between the bolt and the circumferential surface of the bolt.

Furthermore, this invention can also be implemented when a metal plate on one side of a heat insulating panel consisting of a heat insulating material and metal plates laminated on both sides is attached to the rim or the main building.

According to this invention, the mounting protrusion 3 consisting of a pair of protrusion constituent plates 2 that are in contact with each other over the entire length is formed on adjacent metal plates 1 so as to extend continuously, and each protrusion constituent plate 2 The intermediate portions of the ridges are continuously welded and connected in the longitudinal direction of the ridges, and the web of the steel support member 5 having a grooved cross section is brought into contact with the side surface of the ridge 3, and the flange of the steel support member 5 is Since the protrusion 3 and the web of the support member are in contact with the metal plate 1 and are connected by the bolt 4 passed through them, the protrusion 3 strengthens the vicinity of the attachment part of the metal plate 1. In addition, since the portion of the metal plate 1 on the protrusion 3 side is supported by the flange of the support member 5, and the protrusion 3 is supported by the support member 5, the metal plate 1 can be held in a stable state. The bolt 4 that connects the protrusion 3 and the support member 5 is inserted through the protrusion 3 on the outside of the welded part, that is, on the tip end side of the protrusion 3. Even if the through-holes 22 for bolt insertion are provided, the waterproof, moisture-proof, and airtight properties will not deteriorate, and therefore the metal plate 1 can be completely waterproof and airtight.
This provides the effect of ensuring moisture proofing and airtightness and ensuring strong installation.
