Description

[Detailed Description of the Invention] This invention relates to a watertight structure between the upper and lower wall surfaces of a curtain wall, for example, between a spandrel panel and an opening frame.

Conventionally, this type of watertight structure has been constructed by attaching tight material to the proximal ends of upper and lower wall materials in advance at a factory or the like, and then bringing the tight materials into contact with each other at the time of on-site construction to ensure watertightness.

However, in this type of structure, there are disadvantages in that the tight material deforms during construction on site, resulting in uneven contact, or in cases where construction is done at a significant distance.Additionally, wall materials must be installed while taking watertightness into consideration. There was also the problem that the construction required time and effort.

This idea was developed in view of the above circumstances, and after installing the upper and lower wall materials regardless of watertightness, the tight material is stretched over both wall materials and pressure-bonded, thereby reducing the work involved in installing the wall materials. It is an object of the present invention to provide a watertight structure between wall surfaces in a curtain wall, which is characterized by being able to easily obtain stable watertightness.

Examples of this invention will be described below based on the drawings.

In the drawing, the wall material located under -E is spandrel panel 1.
and an opening frame 2, and a spandrel panel 1 is installed between columns 3 and 3 installed at appropriate intervals.
This shows a curtain wall structure in which opening frames 2 and 2 are attached alternately.

The spandrel panel 1 has an upper auxiliary frame 1a, a lower auxiliary frame 1b, and vertical auxiliary frames 1c, 1c attached to the upper F and left and right edges of the back side, that is, the side of the body, respectively, and these auxiliary frames 1a, lb .

1C is formed with a space 1d that communicates with the spandrel panel, and a part of the space 1d, that is, the space 1d of the lower auxiliary frame 1b, is opened to the outside of the room so that the pressure inside the space 1d is equal to that of the outside. It's a formality.

Furthermore, a heat insulating material 1e is provided along the back surface of the spandrel panel 1.

On the other hand, a glass 2a is fitted into the opening frame 2 to form a window.

The manner in which the spandrel panel 1 and the opening frame 2 configured as described above are installed will be explained below. First, the spandrel panel 1 has its upper and lower parts supported by brackets) 4.4'
In this case, the upper support bracket 4 is connected to the channel material 5 fixed on the slab B via the angle material 6, as shown in FIGS. 2 and 7. , and the lower support bracket 4
As shown in FIGS. 2 and 8, the pole 1 is attached via a washer 8 to a support fitting 7 fixed to a beam C installed at the bottom of the slab B or to an empty bracket I to C'. -9 is tightening.

Opening frames 2 are disposed at appropriate intervals on the lower end side of the spandrel panel 1 attached to the body A in this manner, and the aperture frames 2 are attached to the body A with support brackets 1 to 10.

Then, as shown in FIG. 4, the holding member 12 fitted with the material 11.11' is pressed against the tie 1 having two hollow strips from the back side of the spandrel panel 1 and the opening frame 2.
・One piece of material 11 is attached to the ends of the spandrel panel 1 and the opening frame 2 that are close to each other, that is, the lower auxiliary frame 1b.
and the upper frame 2b of the opening frame 2, and then the holding plate 13 is provided to protrude downward from the lower end of the spandrel panel 1.
Tight material 11.
11' is pressed against the spandrel panel] and the opening frame 2.

In this case, the holding member 1 into which the tight members 11 and 11' are fitted
2, before the press bolt 14 is pressed, the locking pawl 12' provided on the opening frame side is locked with the locking part 17 provided on the upper end of the upper frame 2b of the opening frame 2, and the locking claw 12' is moved slightly toward the body A side. It is held at an angle and is fixed to the opening frame 2 by screws 18 after being pressed by a pressing bolt 14.

Additionally, opening frames 2 are similarly attached at appropriate intervals on the -F and end sides of the spandrel panel 1.
The end portions of the spandrel panel 1 and the opening frame 2 that are close to each other, that is, the -L section auxiliary frame ] a and the lower frame 2 of the opening frame 2
Ties 1 to 11.11' are pressed to C by pressure poles) to 14 (see FIG. 5).

In this case, the pressing bolt 14 is screwed to a connecting fitting 19 that connects the spandrel panel 1 and the opening frame 2, and the locking claw 12' of the holding member 12 is connected to the -L portion of the auxiliary frame of the spandrel panel 1. It can be locked to a locking portion 17' provided at 1a.

On the other hand, as shown in FIGS. 6 and 9, the vertical auxiliary frame 1C at the side edge of the spandrel panel 1 is spaced apart from the auxiliary frame 3'a of the cover 3' covering the column. The tip of the material 20 is brought into close contact with the outer surface of the auxiliary frame 3'a to the tongue-shaped tie 1 fitted to the outer part of the vertical auxiliary frame 1C, and the tight material 11°11' A tight member 11'' having a single hollow section connected to the horizontal tight member 11. The cover 16, which is brought into contact with the abutting portion between the neoprene sponge 15 and the vertical tight material 11'' from the back side to complete the wetness between them, holds the neoprene sponge 15 together with the holding member 12.
It is screwed to the auxiliary frame 3'a at both ends.

Although not shown, the vertical frame of the opening frame 2 located coaxially with the vertical auxiliary frame 1C is similarly pressed with the tie I/material 11''.

Further, a horizontal space 21 is formed between the upper auxiliary frame 1a of the spandrel panel 1 and the lower frame 2C of the opening frame 2.

- The outside air that has entered the equal pressure space 1d is indirectly introduced into the space 21 through the opening 22 formed in the upper auxiliary frame 1a, and the vertical auxiliary frame 1C and the auxiliary frame 3 of the cover 3'
Outside air is also introduced from the horizontal space 21 into the vertical space 23 formed between the horizontal space 21 and the horizontal space 21.

Therefore, the horizontal space 21 and the vertical space 23 communicating therewith are both equalized in pressure with the outside air.

Furthermore, an opening 2' is formed in the lower frame 2C of the opening frame 2, and outside air is introduced into the four circumferential spaces 2'' and also into the horizontal space 21.

As explained above, the structure of this invention is such that after the spandrel panel 1 and the opening frame 2 located in the vertical direction are supported by the frame A at a distance from each other, the spandrel panel 1 and the opening frame 2 are A tight material 11.11' is installed across the proximal end of the frame, and this tight material 11.11' is pressed against the spandrel panel 1 and the opening frame 2 by means of a pressing bolt 14, which is a pressing means. The spandrel panel 1 and the opening frame 2 can be easily attached at the time of construction regardless of watertightness, and the spandrel panel 1 and the opening frame 2 can be attached later by straddling the tight material 11, 11' and pressing them together. Therefore, it has the excellent effect of being able to obtain stable watertightness.

In addition, although the above example describes the structure of the installation of the spandrel panel and the opening frame, it is not limited to this type of installation, and similar effects can be obtained with various other wall materials. Therefore, it is naturally included in the gist of this invention.
