Description

[Detailed Description of the Invention] The present invention relates to a panel for an exterior wall of a building, which is used to form an exterior wall surface by a curtain wall construction method.

These exterior wall panels are installed side by side on the exterior of the building so as to surround the exterior of the building, and caulking or gaskets are applied between the peripheral edges of the panels to prevent rainwater from penetrating into the back side. There is.

However, between the edges of each panel, grooves are formed on the surface side vertically and horizontally, like the joints of tiles, so if gaps are formed in the caulking material or gasket applied between the edges, rainwater that has entered the grooves between the panels can become trapped. , From the part where the gap is created, rainwater not only flows from the area near the gap, but also flows from the groove in the part far from the gap and enters the back side.

This invention can minimize the rainwater that enters the back side of the panels even if there is a gap between the panels.
The purpose is to provide panels for curtain walls in buildings that can minimize damage caused by water leakage accidents.

In order to achieve this objective, this invention is such that a molded sealing material 2 is fixed to the peripheral edge surface 1c of the panel 1 in the form of a protrusion extending from the front side to the back side of the panel 1, as shown in the drawings.

In the figure, 1a indicates the front side of the panel 1, that is, the side facing the outside of the building, and 1b indicates the inside of the building, that is, the back side of the panel 1. The molded sealing material 2 is made of elastic rubber such as neoprene rubber, and is formed into a semi-cylindrical shape, and its flat surface is attached to the surface side 1 with adhesive.
Panel 1 is extended in the direction connecting a and the back side 1b.
It is fixed in a protruding manner on the peripheral surface of the.

In the embodiment shown in the figure, molded sealing material 2 is applied to both peripheral edges 1c on both sides of the four corners of a rectangular panel 1 so as to face other panels, and as shown in FIG. When the panels 1 are arranged side by side in a plane and attached to the outer surface of a building, the grooves 3 formed between the panels 1 are divided into small sections in the length direction. The spaces between the panels 1 are made watertight by being filled with caulking material or a band-shaped gasket from the back side 1b.

In many curtain wall construction methods, the watertightness of the joints is achieved through a dual structure consisting of a primary seal and a secondary seal located on the inside. Even if water enters the room, the drainage system that flows out through the space (decompression space) formed between these double seals will properly discharge it to the outside, preventing water from entering the room beyond the secondary seal. A double defense method was often used to prevent this.

In this case, the present invention not only prevents rainwater that has passed through the primary seal from accumulating vertically through the vertical joints, but also accumulates in large quantities in the horizontal joints, forming a thick layer that can be easily removed. The space between the first and second seals is divided to prevent water from entering the inside of the second seal, and the intruding water in each can be quickly discharged.

In addition, in order to achieve this effect, a canister is placed at the intersection of the vertical and horizontal joints that are traditionally formed between panels to drain intruding rainwater that flows down from the top to the outside of the panel. method was being used. After the installation of the panels on the lower floor was completed, the cable van was installed at a height above the joints of the panels on the lower floor.

According to the present invention, it is possible to eliminate such work at a high place, and the number of man-hours required for installing external wall panels can be reduced.

Furthermore, since the space (decompression space) in the direction of the horizontal joint can be subdivided, accumulation of water in this direction can be prevented at the same time.

Furthermore, the present invention plays an important role in the aforementioned open joint where the pressure in the space formed between the primary and secondary seals is made close to the external pressure to control the amount of rainwater that enters this space from the outside. accomplish the goal.

In other words, if this equal pressure space is continuous throughout the building, there will be a large difference in external pressure between the upper and lower floors, and even on the same floor there will be a significant difference between the corners, the front and back of the wind pressure, etc. Because pressure is recognized, in some parts of the above-mentioned equal pressure space, the internal pressure is smaller than the external pressure, and if a hole is made in the primary seal at any of these locations for air introduction There is a part where water blows in from one hole,
Large air currents may also appear within the space.

(This causes water droplets to scatter.) To prevent such defects, it is necessary to subdivide the equal pressure space vertically or horizontally, but according to the present invention, this equal pressure space can be subdivided. The structure can be easily constructed.

In addition, although the example shows an example in which molded sealing material was provided so as to be in contact with the peripheral surface of each panel,
The groove between the panels may be partitioned only by a molded sealing material applied to one panel side. Further, the molded sealing material may be fixed to the panel by fitting instead of using an adhesive. The molded sealing material may be made of a water-impermeable elastic sponge.
