Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a sealing device for a curtain wall constructed of a plurality of panel units arranged vertically and horizontally in a mullion.

[Conventional technology]

In the so-called unit type curtain wall, in which multiple panel units are arranged vertically and horizontally in mullions arranged at predetermined intervals, a tight material is continuously provided around the outer circumference of each panel, and each panel is connected vertically and horizontally. When sequentially installing panels in the left and right direction, the tight materials of adjacent panel units are brought into close contact with each other in an attempt to prevent rainwater from entering the interior of the room.

[Problem that the invention attempts to solve]

When each panel unit is installed in a row, the tight materials of vertically adjacent panel units will be in close contact with each other if the upper panel unit is placed on the lower panel unit from above. It is difficult to place the tight members of the unit in close contact with each other because of the mulled structure. This is because if there is a mullion, it is not possible to press the adjacent existing unit from the side to install the panel unit in parallel, so the panel unit to be installed in parallel cannot be installed directly in front of the existing unit. The panel unit is connected to the panel unit, but at this time, the tight material of the panel unit to be connected collides with the tight material of the existing panel unit, and comes into contact with this while pushing it toward the indoor side. This is because the tight members of the panel units adjacent to each other on the left and right come into contact with each other while being displaced in the indoor/outdoor direction.

For this reason, in the conventional unit type curtain wall, there was a problem in that rainwater easily entered through the contact portion of the tight material between the left and right adjacent panel units.

In view of the above-mentioned problems, the purpose of this invention is to provide a sealing device for a curtain wall that prevents rainwater from entering by improving the close contact between the tight members of panel units adjacent to each other on the left and right sides.

[Means for solving problems]

In the curtain wall sealing device according to this invention, a main piece protruding from the outdoor side of the base is provided with branch pieces that protrude left and right, and a wide part is provided at the tip of the protruding piece that extends from the main piece to the outdoor side. A mullion comprising: a plurality of panel units attached to the branches of the mullion arranged at predetermined intervals and connected vertically and horizontally; The tight materials of the panel units that are adjacent to each other in the vertical and horizontal directions are brought into close contact with each other, and the indoor side of each of the closely-contacted tight materials of the panel units that are adjacent to the left and right is connected to the width of the mullion. The above object is achieved by making it come into contact with the wide portion.

〔Example〕

As shown in FIGS. 1 and 2, 1 is a panel unit, and 2 is a mullion. The panel unit 1 forms a frame body with a vertical frame 3 and upper and lower frames 4 and 5, and the outdoor side of the frame body is Shielding body 6 such as glass or a window that can be opened and closed
, and provide tight support grooves 7, 8, and 9 on the indoor side of the vertical frame 3 and the upper and lower frames 4 and 5, and attach the tight material 10 continuously to these grooves so that four circumferences are formed on the outer circumference of the panel unit 1 on the indoor side. A tight material 10 is provided continuously. Furthermore, a pair of vertical tight members 11 and 12 are attached to the vertical frame 3 in parallel to each other with an interval between them on the outdoor side of the tight member 10.

The mullion 2 has a main piece 14 continuously projecting upwardly and downwardly from a hollow base 13 toward the outdoor side, and branch pieces 15, 15 projecting left and right at the tip of the main piece 14 and the main piece 14
More extended protrusions 16 are provided vertically and continuously, and a wide portion 17 is provided at the tip of the protrusions 16. The vertical frame 3 of the panel unit 1 is fixed to the branch piece 15 with bolts and nuts, and the main piece 14 More prominent bracket 19
Fix the upper and lower frames 4 and 5 with the same bolts and nuts,
Opposing tight material 10, vertical tight material 11, 12
are placed closely together. Moreover, the wide end portion 17 of the protruding piece 16 of the mullion 2 comes into pressure contact with the indoor side of the tight members 10, 10, which are in close contact with each other in the vertical direction as shown in FIG.

As described above, the projecting piece 16 is connected to both tight materials 10, 10.
Since it is pressure-bonded to the existing panel unit,
When newly installing panel units 1 in the left-right direction from the front side (direction from the bottom to the top in the drawing in FIG. 1), the panel units 1 to be installed in a row are
Even if the tight material 10 of the existing panel unit 1 tries to come into contact with the tight material 10 of the existing panel unit 1 in a state where it is displaced toward the outside of the room, since there is a wide portion 17 on the indoor side, it will not shift toward the outside of the room. As shown in FIG. 1, they are brought into close contact with each other in a butt-like manner within the same plane, and this close contact state is stabilized. Further, the wide portion 17 closes the gap 18 formed at the joint portion from the indoor side as shown in FIG.

[Effect of idea]

In the curtain wall sealing device of this invention, the tight members of the adjacent panel units on the left and right, which are in contact with each other, are brought into contact with the wide part of the mullion located on the indoor side, so that the curtain wall sealing device can be installed on the sides of the existing panel units. Even if a new panel unit is installed adjacently from the front side, the tight material of the left and right panel units will not shift in the indoor/outdoor direction, and will remain in close contact with each other on the same surface, providing an excellent sealing effect. play.
