Description

[Detailed Description of the Invention] This invention relates to a rain cover structure for a curtain wall, which is constructed by assembling mullions and blinds each other, each having a mounting groove for fitting a facing material such as glass.

Generally, in this type of rain cover structure, it is difficult to completely prevent rainwater from entering by simply filling the fitting portion of the face material with a sealant, no matter how good the sealant is used. Furthermore, it is clear that the sealing function deteriorates due to aging of the sealing material and deterioration due to thermal expansion and contraction of the open material. Therefore, recently, a method has been adopted in which the rain is contained by eliminating the pressure difference that causes water leakage. This is done by forming a space in mullions or squares, and by making this space equal to the outside pressure, it prevents rainwater from entering.

This idea relates to a rain cover structure that utilizes the above-mentioned isobaric space, in which the vertical space on the side of the mullion and the horizontal space on the side with no opening are communicated with each other, and the installation groove formed in the mullion is provided with an opening. The ends of are fitted together, and a rib is attached to the indoor side of the mullion side, and
A face material is fitted between the raised edge and the mullion through an inner and outer sealing material, and the outer sealing material is continuous in the vertical direction along the mullion, and the outer sealing material supports the face material. At the same time, it can provide a simple and inexpensive structure by ensuring air and water tightness between the mullion and the facing material.

Next, the invented rain cover structure will be explained based on the drawings.

In the drawings, reference numeral 1 denotes a mullion, and on the exterior side of the mullion body 1a, a mounting groove 1a' for a panel 3 is formed in cooperation with a ridge 4. Reference numeral 2 denotes a mullion, and is composed of a mullion body 2a and a mullion cover 2b attached to the exterior side of the mullion body 2a, and the mullion body 2a and the mullion cover 2b form a mounting groove portion 2a'.

When assembling the mullion 1 and the mullion 2 configured as described above, the surface mounting grooves 1a' and 2
The above-mentioned face material 3 is fitted into a', but in this case, an outer seal material 5 and an inner seal material 6 are interposed between the face material 3 and the mounting grooves 1a' and 2a', respectively. The face material 3 is held by the outer seal material 5 and the inner seal material 6. Particularly on the mullion side, a ridge 4 is attached to the indoor side, and an inner sealing material 6 is installed between the ridge 4 and the indoor surface of the panel 3, and between the outdoor surface of the panel 3 and the mullion 1. An outer sealing material 5 is interposed in each.
A vertical space 11 is formed within the mullion 1 by fitting the end of the panel 3 into the groove opening of the mounting groove 1a', and the end of the panel 3 fits into the groove opening of the mounting groove 2a'. A horizontal space 12 is formed within the mesh 2 by fitting the vertical space 11 and the horizontal space 1.
2 are in communication with each other. In this case, mullion 1
A packing 7 as shown in FIG. 3 is interposed on the outdoor side of the joint between the two and the nozzle 2 so as to be continuous with the outer sealing material 5 on the mullion side in the vertical direction, thereby maintaining watertightness in the engaging part. has been done.

On the other hand, an outside air inlet 9 is provided on the outdoor side of the mounting groove portion 2a' of the mesh 2, and is provided on the inside of the mesh drainer on the lower surface of the mesh 2, opens to the outdoor side, and communicates with the horizontal space 12. By introducing outside air into the horizontal space 12 and the vertical space 11 through the outside air introduction port 9, both spaces 11 and 12 have the same pressure as the outside air pressure. Note that another horizontal space 10 is formed between the outdoor side surface of the blind main body 2a and the blind cover 2b, but this horizontal space 10 is blocked from communicating with the vertical space 11 by the packing 7. .

According to the rain cover structure of this invention configured as described above, the vertical space made up of the mullions and the facing material and the horizontal space made up of the mullion and the facing material are communicated with each other. Since both spaces are made to have the same pressure as the outside air pressure through the outside air inlet provided in the eye,
It provides good rain control using the equal pressure principle and has a simple structure, making it easier to install than the conventional method of introducing outside air from both mullions and open spaces. Excellent effects such as the ability to safely introduce outside air can be obtained, and its utility value is remarkable.
