Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a structure of a joint portion of an outer wall panel of an outer wall formed by arranging a plurality of outer wall panels via a gasket.

(Prior Art) As a conventional structure of a joint portion of an outer wall panel, for example, one described in Japanese Utility Model Publication No. 56-1853 is known.

In this conventional structure of the joint portion of the outer wall panel, a plurality of outer wall panels constituting the outer wall each have a gasket on a side surface, and this gasket is formed into a hollow shape having a semicircular cross section. It was attached to two positions on the front and back sides of the.

The outer wall panels are arranged so that the gaskets of the outer wall panels adjacent to each other are in contact with each other.

In addition, the structure of the joint portion of the outer wall panel described in Japanese Utility Model Laid-Open No. 60-141939 is such that after arranging the outer wall panels, one cylindrical gasket is inserted into the joint between the outer wall panels using the lead wire. It was composed of.

(Problems to be solved by the invention) However, in such a conventional joint structure of outer wall panels, first, in the former joint structure of outer wall panels, the two outer wall panels are connected between adjacent outer wall panels. Since the joint of the width of the gasket of the outer wall panel is exposed on the surface of the outer wall, and the gasket is arranged at a position easily visible from the outer wall surface side, there is a problem in that it is unsightly in appearance.

Furthermore, since the gaskets of the adjacent outer wall panels are in contact with each other only at a slight portion close to the line, it is difficult to obtain sufficient waterproof performance only by providing the gasket at one place, and in order to cover it. Since two gaskets have to be installed side by side in front and rear, there is a problem that much labor and high cost are required.

In addition, in the latter structure of the joints of the outer wall panels, although a single gasket can ensure sufficient waterproof performance, the gaskets were inserted in the joints between the outer wall panels after the outer wall panels were arranged. First, insert the lead wire into the joint, tie a gasket to the end of the lead wire,
Furthermore, there is a problem that the work is extremely troublesome because work such as pulling up the lead wire is required.

(Means for Solving Problems) The structure of the joint portion of the outer wall panel of the present invention was made for the purpose of solving the above problems. An outer wall is formed by arranging a plurality of outer wall panels, and adjacent outer wall panels are arranged such that gaskets attached in advance to the side surfaces of both outer wall panels are in pressure contact with each other over a wide surface, and A means in which a raised portion is formed on the side surface of each outer wall panel on the surface side of the outer wall panel from the gasket mounting position so that the joints between the outer wall panels exposed on the outer wall surface at the time of arrangement are narrowed.

(Operation) Therefore, in the structure of the joint portion of the outer wall panel of the present invention, a protrusion is formed on the side surface of each outer wall panel on the surface side of the outer wall panel from the gasket mounting position, and when the outer wall panels are arranged, Since the joints between the outer wall panels exposed on the outer wall surface are narrow, it is difficult to see the gasket from the surface side of the outer wall.

In addition, the adjacent outer wall panels are arranged so that the gaskets attached to their respective side surfaces are widely pressed against each other, so the gaskets must be attached in one place to ensure a sufficient waterproof function. You can

Furthermore, since the gaskets are attached to the outer wall panel in advance before the arrangement, the gaskets can be attached securely and easily, and the attachment position can be determined with reference to the raised portion.

Further, since the gaskets are attached to the side surfaces of the outer wall panels on both sides adjacent to each other, when arranging the outer wall panels, it is not necessary to consider the arrangement order of the outer wall panels and the orientation of the outer wall panels.

Embodiment An embodiment of the present invention will be described in detail with reference to the drawings.

First, the structure of the embodiment shown in FIGS. 1 to 3 will be described.

As shown in FIG. 3, the joint portion A of the outer wall panel of this embodiment is formed by arranging a plurality of vertically long outer wall panels 10 in the vertical and horizontal directions.

This outer wall panel 10 is mainly used for ALC (Autoclaved Light weig
(ht Concrete) and the like, and is reinforced by embedding a reinforcing iron plate 12 therein.

Further, a gasket 20 and a fireproof sponge 30 are attached to all four side surfaces 10a of the outer wall panel 10 with an adhesive or the like, and further, a mounting portion of the gasket 20 and the fireproof sponge 30 on the side surface 10a of the outer wall panel. On the outer wall panel surface 10b side, a raised portion 13 that is laterally raised is continuously formed with the outer wall panel surface 10b.

The gasket 20 is made of a soft material such as rubber and formed in a hollow shape by using a black material that is not excessive, and is bonded to the fire-resistant sponge 30 without any gap.

In addition, each of the outer wall panels 10 is fixed to the steel frame structure B in an independent state.
The gaskets 20, 20 of 0 and the refractory sponges 30, 30 are arranged in the lateral direction and the vertical direction in a state where they are pressed against each other over a wide area. In addition, the ridges of the adjacent outer wall panels 10
The distance between 13, 13 is about 5 mm, considering the tolerance of mounting error.
Is set to.

When arranging the outer wall panel 10, the side surface of the outer wall panel 10
The gasket 20 and the refractory sponge 30 are previously bonded to 10a, and then, as shown in FIG.
Is arranged along the side surface of the steel structure B while moving in a direction perpendicular to the outer wall panel surface. That is, the gasket 20
The contact surface 20a is formed to be slippery so that the gaskets 20 and 20 can move smoothly while contacting each other.

After the outer wall panel 10 is fixed to the steel structure B, the gaskets 20 are in pressure contact with each other.

The fixing structure of each outer wall panel 10 to the steel frame structure B will be described. First, the reinforcing iron plate 12 in the outer wall panel 10 will be described.
Anchor rivet 14 is fixed to and the threaded portion is projected from the back surface 10c of the outer wall panel. Then, with this anchor rivet 14 and the nut 15, a fixing metal fitting made of C-shaped steel
16 is fastened and fixed to the back surface 10c of the outer wall panel, and the fixing metal fitting 16 is further fixed to the steel structure B by bolts 17 and nuts 18.
It has a fixed structure that is fixed by.

Therefore, with the structure of the joint portion of the outer wall panel of the present embodiment, the effects described below can be achieved at the same time.

Of the side surface 10a of each outer wall panel 10 constituting the outer wall,
Since the protrusion 13 is formed on the surface 10b side of the outer wall panel 10 from the gasket 20 mounting position, the outer wall panel adjacent to the outer wall surface when the outer wall panel 10 is arranged and fixed.
The joints S of 10 and 10 are formed narrowly, and the gasket 20 is almost invisible from the joints S. Moreover, since the gasket 20 is black, even if the gasket 20 is slightly visible from the joint S, the gasket 20 looks like a black shadow and is not unsightly in appearance.

Further, since the gaskets 20, 20 attached to the respective side surfaces 10a, 10a of the adjacent outer wall panels 10, 10 are pressed against each other over a wide area, only the gasket 20 is attached at one place. Can ensure a sufficient waterproof function.

Further, the gasket 20 can be securely and easily attached to the side wall 10a of the outer wall panel 10 before fixing the outer wall panel 10 to the steel frame structure B, and the gasket 20 can be attached reliably and easily. As a result, the mounting position can be determined.

Further, the gasket 20 is provided on all the side surfaces 10a of the outer wall panel 10.
Since it is attached, when fixing the outer wall panel 10 to the steel frame structure B, it is not necessary to consider the order of arrangement and the orientation of the outer wall panel 10 in detail.
