Description

[Detailed Description of the Invention] The present invention relates to an exterior material constituting an exterior wall such as a curtain wall.

Conventionally, caulking material was interposed at the joints of exterior materials that make up curtain walls to prevent rainwater from entering, but it was difficult to drain rainwater that had entered the joints or water that had condensed within the joints. Ta.

The purpose of the present invention is to provide an exterior material that can easily drain rainwater that has entered the joints and water that has condensed within the joints when constructing an exterior wall such as a curtain wall. .

In order to achieve this object, the present invention makes the width of the flange on one side of a plate having flanges on four sides larger than the width of the other flanges, and provides weirs protruding from both longitudinal ends of the flange on the side. An edge portion is provided extending outward from the flange end portion of the − side, and a drain hole is provided in the flange portion between the weirs at both ends.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

In FIGS. 1 to 3, reference numeral 1 denotes exterior members disposed adjacent to each other in the vertical and horizontal directions.

The exterior material 1 has flanges 2 on the four sides of a plate 1a, is made of aluminum casting, etc., and is fixed to a building structure via a protrusion provided on the back surface of the plate 1a.

A caulking material 3 is provided between opposing flanges 2, 2 of adjacent exterior materials 1, 1.

The width of the flange 2a on one side of the exterior material 1 is larger than the width of the other flanges 2, and the exterior material 1 is installed with the wide flange 2a as the upper side.

An edge portion 4 extending outward from the plate body 1a is provided from the end of the upper side flange 2a, and the caulking material 3 is connected to the edge portion 4.
A groove 5 is formed between the flange 2a and the flange 2a.

Further, grooves 5 are provided at both longitudinal ends of the flange 2a on the upper side.
A weir 6 is provided to protrude and close the weir 6, and a drain hole 7 that opens into the groove 5 near the weir 6 is provided in the flange 2a.

One end of a drain pipe 8 is fitted into the drain hole 7, and the drain pipe 8 is fixed to the lower surface of the flange 2a with a caulking material 9.

With such a configuration, the caulking material 3 prevents rainwater etc. from entering into the joints of the exterior material 1, and the water condensed inside and the rainwater that has entered will flow in the groove 5 and the weir 6.
As a result, the water can be properly drained from the drain hole 7 near the weir 6.

FIG. 4 shows another embodiment, in which the flange 2a on the upper side has a cross section extending from an opposing part opposite to the flange 2 on the lower side and an end of the opposing part so as to be folded inward of the plate 1a. It consists of a letter-shaped enlarged part, and an end edge part 4 is provided extending outward from the end of the enlarged part.

Therefore, both side walls and the bottom wall of the groove 5 are formed by the enlarged part and the end edge part 4.

A rubber back-up member 10 is inserted from the back side of the plate 1a between the opposing part of the upper flange 2a and the lower flange 2.
and caulking material 3 are interposed in this order.

In addition, a drain pipe 8 consisting of a short pipe is cast into the widened part of the upper flange 2a so that one end opens into the groove 5,
A flexible tube 11 is connected to the other end of the drain pipe.

Reference numeral 12 denotes a protrusion formed around the drain pipe 18 on the lower surface of the expanded width in order to ensure the necessary wall thickness for casting the drain pipe 8.

Also in this configuration, waterproofing and drainage are achieved in the same manner as above.

As explained above, according to the present invention, an edge portion extending outward from the end of the flange on one side of the plate body is provided, and weirs are provided at both longitudinal ends of the flange, and both ends Since drainage holes are provided in the flange portion of the fence, when an exterior wall such as a curtain wall is constructed, water that has entered the joints of the exterior material and water that has condensed inside can be drained well.
