Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a watertight structure in a curtain wall unit in which a plurality of curtain wall units are installed adjacent to each other.

[Conventional technology]

Conventionally, in the watertight structure of this type of curtain wall, the joints between curtain wall units were filled with a seal, and watertightness was maintained by the adhesive force of this seal.

[Problems to be solved by the invention] This method has variations in performance depending on the material of the seal and the quality of the on-site seal construction, and it is nearly impossible to completely install the seal over the entire length. The problem was that it was difficult to obtain a proper sealing function. Furthermore, there have been problems such as peeling or breakage due to deterioration of the seal, or stress applied to the seal due to heat shrinkage of the curtain wall, resulting in peeling or breakage of the seal. As described above, in the conventional watertight structure of this type, there is a great concern about variation in seal performance or long-term performance maintenance, and therefore improvements in this point are currently desired.

[Means for solving problems]

This invention was made in view of the above circumstances, and in a curtain wall in which a plurality of curtain wall units are installed adjacent to each other, between the upper and lower parts of the curtain wall units,
A horizontal space is formed between the left and right sides of the curtain wall unit with an opening whose indoor side is closed off with a tight material and whose outdoor side is communicated with the outside. Forming a vertical space closed by a watertight slat plate having a plurality of surface portions installed in a watertight state between these left and right curtain wall units which are adjacent to each other on the outside, and forming a vertical space in the watertight slat plate. The present invention aims to provide a watertight structure in a curtain wall unit in which the vertical space is divided into a plurality of spaces each communicating with the horizontal space by a plurality of branching surfaces.

[Effect]

The present invention will be explained in detail below based on the accompanying drawings.

The drawing shows a curtain wall structure in which a curtain wall unit forming a blind window A and a curtain wall unit forming a revolving window are assembled. upper frame 2 surrounding the four circumferences of 1;
The revolving window B is composed of a lower frame 3 and vertical frames 4, 4, and the rotating window B includes a glass 5 as a face material, an upper stile, a lower stile 7, and vertical frames 8, 8 surrounding the four circumferences of this glass 5. A rotating part 9 consisting of an upper frame 19, a lower frame 11, and vertical frames 12, 12 assembled around the four circumferences of this rotating part 9.
and a frame portion 13 consisting of. The upper frame 2 or 10 and the lower frame 3 of these windows A and B
or 11 are anchor 14 and bolt 1 respectively
It is fixed to the frame C via 4'.

The horizontal joint portions of the fitted window A and the rotary window B configured as described above are connected via a watertight mesh plate 15, as shown in FIGS. 2 and 3. At this time, the watertight mesh plate 15 has an outdoor side surface 15a, an indoor side surface 15b, and both surfaces 15.
The intermediate surface 15c located between the surfaces 15a, 15b, and 15b and the connecting portion 15d connecting approximately the center of each surface 15a, 15b, and 15c form a substantially square cross section, and each surface 15a, 15b, and 15c The distal end legs 15', 15'... of the unit engage with the vertical frame 4 or 12 of the adjacent unit A, A or A, B, respectively, thereby creating a plurality of vertical spaces or spaces between the vertical frame 4 or 12. An auxiliary space 16 is provided between the outdoor side surface 15a and the intermediate surface 15c, and an auxiliary space 16 is provided between the indoor side surface 15b and the intermediate surface 1.
A vertical space 17 is formed between it and 5c. In this case, the auxiliary space 16 and the vertical space 17 are each divided into two rooms by a connecting portion 15d. Further, tight members 18, 18 are formed around the indoor side of each adjacent unit A, A or A, B, and these tight members 18, 18 are connected to the indoor side surface 15b of the watertight slat plate 15. A space 19 is formed between them.

On the other hand, the vertical joints of the units A and B form a horizontal space 20 communicating with the vertical space 17, as shown in FIGS. They are connected via tight members 18, 18 that are fitted on the indoor side and engage with each other. At this time, the horizontal space 20 includes a rainwater blocking plate 21 which is a hanging wall hanging from the lower end of the lower frame 3 or 11 on the outdoor side of the unit A or B located above.
The rainwater blocking plate 21 at the upper end of the unit A located below communicates with the outdoor side through an opening 23 formed by a water return member 22 which is an upright wall erected on the indoor side. Therefore, outside air can be introduced into the vertical space 17, the auxiliary space 16, and the space 19 through the horizontal space 20. In this case, the mutually communicating unit spaces 24 formed in the frames 2 to 4 of the fixed window A are communicated with the outside air through the air inlet 25 provided in the lower frame 3, and the unit spaces 24 of the rotating window B The first unit spaces 26 formed in the frame part 13 and communicating with each other are communicated with the outside air through an air inlet 27 provided in the lower frame 11, and the frame part 13 and each of the frames 6, 7, and 8 are connected to each other. A second unit space 28 which is formed between the two and which communicates with each other is connected to the first unit space 26 through an air inlet 29 provided at another location of the lower frame 11.
It is communicated with.

Although the above embodiment describes a curtain wall structure in which a fitted window and a rotating window are assembled, the same effect can of course be obtained in a curtain wall structure in which various curtain wall units of other forms are arbitrarily assembled. It is something that can be done.

〔Effect of the invention〕

The watertight structure of the present invention configured as described above has an opening 2 in which the indoor side is closed with a tight material 18 between the upper and lower curtain wall units A, A or A, B adjacent to each other, and the outdoor side communicates with the outside.
3, and communicates with the horizontal space 20 between the left and right sides of each curtain wall unit A, A or A, B, the indoor side is closed with a tight material 18, and the outdoor side is adjacent to each other. A vertical space is formed between these left and right curtain wall units A, A or A, B and is closed by a watertight mesh board 15 having a plurality of surface parts installed in a watertight state, and the watertight mesh is Board 15
Since the vertical space is divided into a plurality of spaces 16 and 17 that communicate with the horizontal space 20 by a plurality of branching surfaces formed in 20, 16,
It is possible to make the pressure inside each space 17 equal to the pressure of the outside air, and therefore, it is possible to prevent rainwater etc. from entering the room from the outside due to the equal pressure principle, and in the event that the inside of the spaces 20, 16, 17 Even if rainwater enters the space, it can be quickly discharged to the outside through the space 16. Moreover, the installation is extremely simple, as it only needs to be assembled between each curtain wall unit A, A or A, B, which are assembled on site, and the construction time is significantly reduced compared to construction using conventional sealing materials. can be done. Furthermore, since a watertight eye board is interposed in the vertical space, the vertical space is divided into left and right sides and blocked off, making it possible to form a safe equal-pressure space without being affected by adjacent spaces. It becomes possible. (For example, in the case of building construction, the conditions for the left and right units may be positive pressure on one side and negative pressure on the other. In this case, even if you try to equalize the pressure on the positive pressure side, the air will be drawn to the negative pressure side.) (It had the disadvantage that it was stretched and could not form a regular equal pressure.)
