Description

[Detailed description of the invention] This invention relates to an improvement in the watertight structure of a curtain wall.

BACKGROUND ART In general high-rise buildings and the like, rain protection structures that utilize the isobaric principle are widely used, in which openings are provided in frame members such as mullions, blinds, or frames that make up curtain walls.

Generally, the openings provided in these frame components are mainly located in areas where raindrops are less likely to come into contact, such as the bottom end without a hole, but there are cases where it is unavoidable to provide openings in areas that are more likely to be hit by raindrops. be.

Therefore, conventionally, as shown in FIG. 1, a draining plate C is provided on the front surface of the mesh a with a drain plate d to cover the opening provided in the mesh a, or as shown in FIG.
For example, if a baffle f is installed inside the mullion e, the raindrops can be directly directed to the indoor tight material g or the panels due to the kinetic energy of the raindrops or the difference between the internal pressure of the mullion and the outside pressure that occurs instantaneously. This prevented it from hitting the end of h.

However, in these structures, it takes time and effort to attach the draining plate C and the baffle f, which increases the cost, and there is also a fear that the attachment may be made by mistake or forgotten.

This idea was created in view of the above circumstances, and by protruding a part of the panel holding member to cover the opening, it eliminates the need for draining plates and baffles, simplifies construction, and reduces costs. The present invention aims to provide a watertight structure for a curtain wall, which is characterized by being able to achieve the following.

Examples of this invention will be described below with reference to FIGS. 3 to 6.

3 and 4 are cross-sectional views showing another embodiment in which the watertight structure of this invention is used in a mullion, and in the figures, 1 is a mullion, and 2 is engaged with the side of mullion 1. A groove 3 is formed between the ribbed edge 2 and the mullion 1, and the panel 4, whose edge 4' protrudes into the load 3, is made of tight material on the indoor side. 5, and is fitted and fixed by a holding member 6 on the outdoor side to form a fitted window.

In addition, when installing the panel, a space 7 is formed between the groove 3 and the panel 4, and this space 7 is communicated with the outside through an opening 8 provided in the mullion 1, and the inside of this space 7 is filled with outside air. (Hereinafter, this space 7 will be referred to as the outside air equal pressure space).

Then, the holding member 6
A fin 9 is provided protruding from the opening 8.
is covered, and the inside of the outside air equal pressure space 7 is divided into two chambers 7a and 7b that communicate with each other.

In this case, in the first embodiment shown in FIG. 3, the fin 9 and the panel mounting communicate with the chambers 7a and 7b through the gap 10 between the groove 3, and in the second embodiment shown in FIG. chamber through the provided communication port 11? a and 7b are in communication.

The communication port 11 is provided at a location other than on the same plane as the opening 8, so that the outside air entering the chamber 7a through the opening 8 does not directly enter the chamber 7b.

In the watertight structure of this invention constructed as described above, the panel mounting is carried out in an outside air equal pressure space 7 formed by the groove 3 and the panel 4.
The two chambers 7a and 7b communicate with the outside through an opening 8 provided in the mullion 1, and communicate the outside air equal pressure space 7 with each other by means of fins 9 protruding from the panel holding member 6 and covering the opening 8. Since the outside air pressure space 7, that is, the inside of the chambers 7a and 7b is kept at the same pressure as the outside air, the watertightness between the mullion 1 and the panel 4 can be improved based on the equal pressure principle. In addition, even if rainwater enters the outside air isobaric space 7 due to the kinetic energy of raindrops, the outside air and rainwater can be separated by the fins 9, so that the indoor side chamber 7
Since rainwater is not allowed to enter into the interior of the interior, it is possible to safely shut down the rain based on the principle of equal pressure.

FIG. 5 is a longitudinal cross-sectional view showing a mode in which the watertight structure of this invention is used in a blind part, and shows panels 4,
4 is attached, and the upper panel is attached to the outside air equal pressure space 7 formed by the groove 3' and the panel 4 with an opening provided in the open space 12, that is, an outside air inlet and a water drain. It communicates with the outside via a port 13.

Then, a fin 9 formed by protruding a part of the panel holding member 6 downward covers the outside air inlet/drain port 13, and divides the outside air equal pressure space 7 into two chambers 7a and 7b that communicate with each other. Therefore, the same effects as those of the above-mentioned first and second embodiments are obtained.

Note that 14 is a piece member that is disposed within the chamber 7b of the outside air equal pressure space 7 and holds the panel 4.

FIG. 6 is a cross-sectional view showing an embodiment in which the watertight structure of this invention is used in a rotating window section.

That is, the panel mounting groove 3'' provided on the lower stile 16 of the revolving window 15, and the panel or glass 17 installed in the groove 3'' form an outside air equal pressure space 7, and the lower sill This outside air equal pressure space 7 is communicated with the outside through an opening provided in the outside air inlet/drain port 18 provided in the outside air inlet 16, and outside air is communicated with the outside through fins 9 that protrude downward from a part of the panel holding member 6. In addition to covering the inlet/water drain port 18, the outside air equal pressure space 7 is divided into two chambers 7a and 7b that communicate with each other, so as to have the same effect as the above-mentioned first and second embodiments. be.

Reference numeral 19 denotes a sealing material attached to the lower stile 16, which maintains watertightness between the lower stile 16 and the blind 12.

In addition, when the watertight structure of this invention is used in a closed or rotating window part, the same parts as in the first embodiment described above or parts that are the same as each other will be given the same reference numerals and the explanation thereof will be omitted. be.

Note that instead of the panel 4 shown in the embodiments of FIGS. 3 to 5, it is possible to support a window frame such as a rotating window, a sliding window, a bay window, etc., and in this specification, all of these are referred to as panels. It is called.

As explained above, according to the watertight structure of this invention,
Panel mounting on frame components such as mullions, blinds, or frames that make up a curtain wall is done by using grooves and the edges of the panels fitted into the grooves with appropriate retaining members. The outside air isobaric space is communicated with the outside through an opening provided in the frame component, and a fin is provided protruding from a part of the holding member to cover the opening. Since the interior is divided into two rooms that communicate with each other, the watertightness between the frame components and the panel can be improved due to the equal pressure principle, and the kinetic energy of raindrops can prevent rain and ice from forming. Even if outside air enters the equal-pressure space, the fins separate the outside air and rainwater and prevent rainwater from entering the indoor chamber, making it possible to safely shut down the rain using the equal-pressure principle.

In addition, according to this invention, a part of the panel holding member is provided with a protruding fin to prevent rainwater from entering.
Components such as draining plates and baffles are no longer required, and construction can be simplified and costs can be reduced.In addition, accidents such as mistakes or forgetting to install draining plates and baffles can be avoided. Since it can be solved, its utility value is remarkable.

In addition, although the above embodiment describes a curtain wall structure having a fitting part and a rotating window part, it can also be applied to other curtain wall structures, and the same effect can be obtained.
