[Industrial applications]

 INDUSTRIAL APPLICABILITY The present invention is used in the technical field of plate wall mounting processing of a relatively high-rise building such as a mechanical multistory parking lot, and particularly relates to a connecting and fixing structure of metal outer wall plates.

[0002]

[Prior Art]

 Generally, a metal outer wall plate (hereinafter simply referred to as an outer wall plate) that covers the outside of a building frame is attached by screwing the base end of one outer wall plate to the frame, and then the flat plate of this outer wall plate. Both ends of one outer wall plate are joined by screwing the sealing material onto the flat end of another outer wall plate by overlapping the flat end of the outer wall plate with the sealing member. It was installed.

[0003] Thereafter, when the outer wall board mounting process for the lower floors is completed by repeating this processing procedure, this mounting process is sequentially advanced toward the upper floors.

Further, by interposing a drainer in each of the upper and lower joints, such as between the base and the outer wall plate of the lower floor, between the outer wall plates of each floor, and between the outer wall plate of the uppermost floor and the headboard, rainwater can be inserted. Was prevented from entering.

[0005]

[Problems to be solved by the device]

 However, in the above-mentioned conventional outer wall plate mounting process, the lap joint part of each outer wall plate is located away from the work position of the worker in a place where it is difficult to reach, so the screw stop work of the lap joint part is easy. Nonetheless, this problem becomes more serious as the width of the outer wall plate along the outer edge of the frame becomes wider.

[0006] Therefore, if an attempt is made to force the mounting process, the worker will have an unstable work posture in which the body is greatly pushed out to the outside of the outer wall plate, which is not preferable in terms of safety management of field work. May be caused.

Therefore, it is necessary to install an outer working scaffold at every work site without exception, and the outer working scaffold becomes larger and more expensive as the floor area and height of a building increase. There was a problem.

In view of such conventional circumstances, the present invention makes it possible to safely mount an outer wall plate without providing an outer scaffold, even if it is a high-rise building, and further, to connect both ends of the outer wall plate. It is an object of the present invention to provide a connecting and fixing structure of a metal outer wall plate that can prevent rainwater from entering without using a sealing material in the hands.

[0009]

[Means for Solving the Problems]

 The metal outer wall plate connecting and fixing structure of the present invention is a metal outer wall plate that is sequentially connected and fixed to a frame so as to surround the outer periphery of a building, and each of these outer wall plates is a shaft. The end on the opposite side along the body edge of the set is formed into a box-shaped joint that is bent into a box-shaped cross section, while the end on the proximal side can be vertically engaged with the box-shaped joint. A Z-shaped joint formed on a Z-shaped joint bent to have a Z-shaped cross section, and a box-shaped joint of another outer wall plate is engaged with the Z-shaped joint of one outer wall plate fixed to the furring strip to form another outer wall plate. By pulling the other side of the outer wall plate toward the hand side and fixing the Z-shaped joint side of the other outer wall plate to the furring strip, both joints in the engaged state elastically contact each other to prevent the ingress of rainwater and the like. It is a thing.

[0010]

[Action]

 By engaging the box-shaped joint of another metal outer wall plate from above with the Z-shaped joint of one metal outer wall, and pulling the other metal outer wall plate toward the hand side, the Z-shaped joint is slightly reduced. When the shape is changed to, the Z-shaped joint and the box-shaped joint make elastic contact with each other by the repulsive force of the Z-shaped joint to return to the original posture, and it is possible to prevent the intrusion of rainwater and the like.

While maintaining this elastic contact, by fixing the proximal side of the other metal outer wall plate, that is, the Z-shaped joint part side to the furring strip of the frame with the set screw, the other metal outer wall plate Both ends are easily connected and fixed, and this connection and fixing work can be repeated while maintaining a safe posture inside the building.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

The hand side in this description indicates the arrow side in the outer wall plate connection direction D.

A metal outer wall plate 1 (hereinafter, simply referred to as outer wall plate) 1 shown in FIGS. 1 and 2 is used to form an outer wall body 21 shown in FIG. Each corner outer wall plate 23 surrounding the outside of, for example, four corner posts 22 of an object (whole illustration is omitted), and four hand side bellows outer wall plates 24 connected to the hand side of each corner outer wall plate 23. , Four anti-hand side bellows outer wall plates 25 connected to the other hand side of each corner outer wall plate 23, and a plurality of said ones sequentially connected from one hand side bellows outer wall plate 24 of one corner outer wall plate 23. It comprises an outer wall plate 1 and four adjusting outer wall plates 26 for connecting the last piece of the outer wall plate 1 to the counter-hand side bellows outer wall plate 25 of another corner outer wall plate 23.

As shown in FIG. 1, the outer wall plate 1 is a box shape in which the end on the opposite side (right side in FIG. 1) along the furring strip 11 of the building frame is bent into a box-shaped cross section. One end formed on the joint portion 2 (the left side in FIG. 1) is bent into a Z-shaped cross-section that can be fitted in the upper and lower directions with the box-shaped joint portion 2 of the other outer wall plate 1. Formed on the Z-shaped joint 3.

The box-shaped joint portion 2 has a gap 4 formed at the bent end portion so that the Z-shaped joint portion 3 of another outer wall plate 1 can be engaged with the box-shaped joint portion 2.

The Z-shaped joint portion 3 is formed with a gap 5 at the bent end portion, with which the box-shaped joint portion 2 of the other outer wall plate 1 can be engaged, and the Z-shaped joint portion 3 is provided on the inner side of the gap 5. A floating space 6 is formed to allow a slight deformation of the part.

That is, as shown in FIG. 2, the Z-shaped joint portion 3 of one outer wall plate 1 fixed to the furring strip 11 is engaged with the box-shaped joint portion 2 of the other outer wall plate 1 to form another outer wall. By pulling the plate 1 toward the hand side and fixing the Z-shaped joint 3 side of the other outer wall plate 1 to the furring strip 11 with the set screw 7, both joints 2 and 3 in the engaged state are Z-shaped. The spring effect caused by slight deformation of the shaped parts makes elastic contact with each other to prevent rainwater and the like from entering.

At the proximal end of the proximal bellows outer wall plate 24, a Z-shaped joint 24 a similar to the proximal end of the outer wall plate 1 is formed.

Further, a Z-shaped joint portion 25 a, which is different from the end portion on the proximal side of the outer wall plate 1, is formed at the end portion on the opposite proximal side of the bellows outer wall plate 25 on the opposite side.

Next, the construction order of the outer wall body 21 in the above embodiment will be described.

First, each corner outer wall plate 23, and the front side bellows outer wall plate 24 and the non-hand side bellows outer wall plate 25 that are connected to each corner outer wall plate 23 are respectively set with a set screw (not shown) to the furring strip 11 Fixed to.

Next, the box-shaped joint portions 2 of the outer wall plate 1 are engaged with the Z-shaped joint portions 25 a of the front side bellows outer wall plates 25 of the respective corner outer wall plates 23 from above to make the outer wall plates 1 Z-shaped. The Z-shaped joint portion 2 side of the outer wall plate 1 is fixed to the furring strip 11 with the setscrew 7 in a state where both joint portions 2 and 3 are elastically contacted with each other by pulling the joint portion 2 together with the joint portion 2. The outer wall plate 1 is sequentially connected by repeating the procedure shown in FIG.

That is, this connection procedure includes a first step S1 of standing the outer wall plate 1 on the floor surface F, a slinging of the outer wall plate 1 to suspend the outer wall plate 1 from above, and the other outer side Connection of each outer wall plate 1 is performed by the second step S2 of engaging the outer wall plate 1 with the above-described engagement, and the third step S3 of pulling the engaged outer wall plate 1 toward the hand side and fixing it to the furring strip with a set screw. Is easily done.

The steps S1, S2, S3 are all carried out inside the building and in a stable posture, so that the work outer scaffold can be omitted.

When the final steps of the outer wall plate 1 are fixed to the furring strip 11 by repeating the above steps S1, S2, S3, the Z-shaped joint portion 3 of each last outer wall plate 1 and each corner outer wall plate. The outer wall plate 26 for adjustment is engaged with both the joint portions 3 and 25a while attracting the Z-shaped joint portion 25a of the bellows outer wall plate 25 on the other side connected to the outer wall plate 23. The construction of the body 21 is completed.

In addition, a drainer is interposed between the base and the outer wall bodies 21 on the lower floors, between the outer wall bodies 21 on each floor, and between the outer wall board 1 on the uppermost floor and the headboards, so that rain water is interposed. Intrusion is prevented.

[0028]

[Effect of the device]

 According to the connection fixing structure of the metal outer wall plate of the present invention, the Z-shaped joint portion of one outer wall plate is engaged with the box-shaped joint portion of the other outer wall plate to pull the other outer wall plate toward the hand side, Since the Z-shaped joint side of the outer wall plate is fixed to the furring strip, each outer wall plate is maintained on the inner side of the building and in a safe posture. However, the construction cost can be significantly reduced by omitting the outer scaffold for work.

Further, both side ends of the outer wall plate are elastically contacted with each other by the spring effect due to the slight deformation of the Z-shaped joint portion, so that intrusion of rainwater is prevented without using a sealing material. In addition, it has the great advantage that the work for constructing the outer wall body is significantly improved, along with the omission of the work scaffold.
