Description

[Detailed description of the invention] This invention relates to an improvement in the structure of the ribbed attachment used when fitting face materials such as glass and panels in curtain walls, sashes, etc.

Conventionally, when glass, etc. is fitted into a frame consisting of left and right vertical frames and upper and lower horizontal frames in curtain walls, sashes, etc., when the frame is incorporated into the wall or steel frame by screwing or welding and cannot be disassembled. is one of the four corner frames that make up the window frame.
Glass etc. were fitted using the so-called press-edge method, which consisted of two molds at one to four locations.

However, due to dimensional errors and errors in the cutting dimensions of the rim, the installation of the frame sometimes has the disadvantage of creating gaps at the longitudinal ends of the rim, which reduces airtightness and watertightness, especially when installing the rim. It was difficult for those with a structure to be installed from the indoor side to exhibit their sealing and waterproofing effects.

Furthermore, conventionally, it has not been considered to interpose gaskets at both ends of the rim, and the solution has been to cut the rim to eliminate errors as much as possible.

For this reason, there is almost no gap between the frame or the rim that both ends of the rim come into contact with, so when installing the rim, there is a risk that the edge of the end of the rim may damage the surface of the frame and the rim that it comes into contact with. .

This idea was made in view of the above-mentioned drawbacks, and in order to eliminate the gap between the ridge abutting portions, the longitudinal ends of the ridges are brought into contact with the frame body, or between the ridges are brought into contact with each other. The object of the present invention is to provide a rim structure for curtain walls, sashes, etc., in which the rim is attached within a frame by sandwiching an elastic packing between the two.

Embodiments of this invention will be described below with reference to FIGS. 1 to 5.

Fig. 1 is a front view showing an example of an inset sash window in which the ribbed edge mounting structure of this invention has been implemented, and numerals 1 and 2 are vertical frames;
3 and 4 are the upper frame and the lower frame, 5 is a face material such as glass, 6 is a ridge attached to the frames 1, 2, 3.4, and 7 is a contact portion of the longitudinal end of this ridge 6 ( It is an elastic gasket made of synthetic rubber, synthetic resin, etc. that is sandwiched between ridges.

Figure 2 is a front view and central cross-sectional view of the structure in which the ribbed edge is attached to the glass opening in the curtain wall.
The figure and FIG. 4 are the III-III sectional view and IV of FIG.
-IV sectional view, 1 is a vertical frame, 3 is an upper frame, and 4 is a lower frame, so as to form an opening for fitting the glass 5 to the back surface of the outdoor side A front part of the vertical frame 1. A ridge 6 is attached from the indoor side B.

The glass 5 located in the opening is supported and fitted with a tight material 8 from the rear and a back-up material 9 and a seal 10 for watertightness from the front.

The gasket 7 is sandwiched between the longitudinal end of the ridge 6 and the upper frame 3 and lower frame 4 with which it comes into contact, and its shape is as shown in FIG. 4 and FIG. It has an abbreviated shape that matches the shape of the bent part facing the indoor side B of No. 6, and
A step 7a having a thickness equal to the thickness of the ridge 6 is formed on the outer periphery of the ridge 6, and the longitudinal end of the ridge 6 is placed on the step 7a so that the outer surface of the ridge 6 and the packing 7 are aligned. The portion 7a is securely locked together with the sleeve 7b located behind the portion 7a.

Furthermore, an L-shaped groove 11 with one end opening on the side surface is formed on the back surface of the packing 7 to divide the abutting part of the packing 7 into two, and the fin-like bodies 7C and 7d are formed.

These fin-like bodies 7C and 7d can make good contact with the gasket 7, and even if water in the frame enters from the fin-like body 7C due to capillary action, it can be cut off in the groove 11 space. Since the water accumulated in the groove 11 returns to the frame through the opening by locating the opening facing the inner space of the frame, it is possible to prevent the water from seeping into the indoor side B.

As mentioned above, this invention is based on the structure of curtain walls, sashes, etc., in which a plate such as glass is fitted into a frame consisting of left and right vertical frames and upper and lower horizontal frames by attaching the ribbed edges. An elastic packing is sandwiched between both ends in the longitudinal direction and the frame or the rim that abuts the both ends, and the packing has a step portion equal to the thickness of the edge cut surface of the end of the rim, and the step. It is formed by a sleeve that rises up along the back side of the rim and abutting part, so when installing the rim, the edge of the end of the rim allows the surface of the frame and the rim to come into contact with each other. will not be damaged.

Moreover, even without special precision in cutting the length of the rim, no gaps are created within the elastic range of the packing, improving airtightness and watertightness, and furthermore, rattling in the longitudinal direction of the rim can be prevented.

Furthermore, since errors in the mounting dimensions between the frames to which the ribbed edges are attached and the cutting dimensions of the ribbed edges are absorbed by the packing, work efficiency is improved during the attachment.
