Description

[Detailed description of the invention] Industrial application field This invention relates to a sash mounting structure.

BACKGROUND ART FIG. 3 shows a conventional sash mounting structure. In the figure, reference numerals 1 and 1 indicate a frame frame of a building each consisting of a C channel, and 2 an external wall panel.
and tighten the nut 5 screwed into the bolt 3 on the outside of this plate 4 to press down one piece 6 of the outer wall panel 2 with the plate 4, and at the same time, at the other end of this holding plate 4, One piece of the sash 7 is pressed against and fixed to the outer surface of the frame 1.

On the other hand, in a different method, an inner support piece protrudes toward the center of the opening from a fixing fitting attached to the shaft frame, and a screw such as a bolt inserted into this inner support piece from inside is used to secure the inner support. There are some that are attached to the sash and a fixed piece that is integrally formed with the sash.

Problems to be solved by the invention In the sash mounting structure shown in Figure 3 above,
The sash 7 is fixed by bolts 3 that protrude from the gap between the frame frames 1 and 1, and these bolts 3 are installed at the site when the outer wall panel 2 is installed. The sash 7 must also be installed on site, which has the drawback of increasing the number of man-hours required for on-site construction.

Therefore, one possible way to reduce such on-site man-hours is to integrate the sash 7 and the frame 1 in advance at the factory and transport them to the site. With the frame structure, the sash and frame are completely integrated, so there is a drawback that adjustments cannot be made on site.

On the other hand, the latter structure, in which the inner support piece is attached to the sash or a fixed piece formed integrally with the sash by a screw such as a bolt inserted from the inside of the inner support piece, does not have such a drawback, but
The problem with the fixing piece on the sash side is that it is fixed to the sash or formed integrally with the sash in this way. That is, the fixing piece on the sash side may be located at one or more points in the longitudinal direction, but if it is formed integrally with the sash, since this type of sash is extrusion molded, it must be formed over the entire longitudinal length, which is a drawback in that it results in waste of expensive aluminum material and increases costs, and if it is fixed to the sash, labor such as spot welding is required, which also increases costs.

This invention aims to eliminate such conventional drawbacks.

Means for Solving the Problems In order to solve the above problems, this invention consists of a board and an inner support piece protruding from the side surface of the board, and a groove that opens in the inside and outside directions of the board. consisting of an inner fixing fitting that is fitted into and attached to the lip of a vertical frame frame that is made of a C channel and surrounds the opening, and an outer fixing fitting that is attached to the sash outside of this inner fixing fitting. A fitting groove is formed in this outer fixing metal fitting by folding back the end of the portion located outside the shaft frame, and the protruding piece of the sash is fitted into this fitting groove to be attached. The inner supporting piece projects from the inner fixing fitting toward the center of the opening, and the outer supporting piece faces the inner supporting piece and projects toward the inside of the building from the outer fixing fitting. Pull the outer support piece inward using the bolt inserted from the inside, and make sure that it is fixed with the end of the sash fitted with the protruding piece pressed against the outer surface of the frame frame. This is a characteristic feature.

Function: Outer support piece 21 protruding from the sash 14 side
, the inner support piece 1 protruding from the shaft frame 12
8, it can be integrated into the frame 12 in advance and transported to the site. Further, by operating the bolt 28 from inside the building, the sash 14 can be removed or its attachment position can be adjusted.

Embodiment Hereinafter, the configuration of this invention will be explained based on the illustrated embodiment. In FIGS. 1 and 2, 11
13 indicates an inner fixing fitting attached to the shaft frame 12, and 13 indicates an outer fixing fitting attached to the sash 14 side. In this embodiment, these fixing fittings 11 and 13 are used to hold the sash 14 on the axis. It is attached to the assembly frame 12.

The inner fixing fitting 11 has substantially U-shaped engagement members 15, 15 on both left and right ends thereof, and is fixed to the substrate 1 with the grooves 16, 16 facing outward in the left-right direction.
7, and an inner support piece 18 projecting from the center of the substrate 17 toward one side. Inner support piece 1
8 is formed with an elongated hole 19 that is long in the horizontal direction, that is, in the left-right direction of the building opening.

The outer fixing fitting 14 is formed by bending one end of the substrate 20, which is bent into an L shape when viewed from a plane, at a substantially right angle in a direction opposite to the bending direction of the L shape. Similarly, the other end of the substrate 20 is folded back 23 in a U-shape to the outside in the direction opposite to the bending direction of the substrate 20, and a fitting groove 22 is formed between it and the substrate 14.
was formed. A bolt hole 23 is formed in the outer support piece 21 facing the elongated hole 19 of the inner support piece 18, and this bolt hole 23
A nut 24 is welded in advance to the back side.

The inner fixing metal fitting 11 formed as described above is
As shown in the figure, the grooves 16, 16 of the U-shaped engaging members 15, 15 are fitted into the respective lips 25, 25 of the shaft frame 12 consisting of a C channel, and the inner support piece is thereby attached. 18 to opening 26
protrude toward the center of the

On the other hand, the outer fixing fitting 13 is attached by fitting a fitting groove 22 formed at one end of the substrate 14 into a protruding piece 27 of the sash 14 that protrudes on the side opposite to the opening 26, thereby providing outer support. The piece 21 is opposed to the inner support piece 18. Next, the inner support piece 18
The tip of the bolt 28 inserted from the inside of the building is screwed into the nut 24 attached to the outer support piece 21, thereby pulling the outer fixing fitting 13 inward and removing the protrusion of the sash 14. The piece 27 is inserted through the base plate 14 of the outer fixture 13.
It is pressed against and fixed to the outer surface of the frame 12.

Then, when the sash 14 is transported to the site with the sash 14 fixed to the frame 12 in this way, and it is necessary to adjust or remove the sash 14 at the site,
Work is done by loosening or removing the bolts 28 from inside the building. In addition, the cross section of FIG. 1 is shown by cutting the vertical frame of the sash 14 in the horizontal direction, and the vertical frame of the sash that faces one of the vertical frames is
In this figure, it is located on the right side. 29 in FIG. 1 indicates a picture frame.

Effects of the invention As described above, with this invention, the sash can be integrally fixed to the frame in advance and transported to the site, so the work of installing the sash on the site is omitted, and the number of on-site man-hours can be reduced accordingly. can.
In addition, since the sash is attached with bolts, it can be adjusted or removed by loosening or removing the bolts. Since it is inserted from the side, it has the advantage of being able to work from inside the building. That is, in the conventional example shown in Fig. 3, loosening nuts for removing or adjusting the sash must be done from the outside of the building, and such work is difficult to do on second-floor windows where scaffolding is not installed. Although it was very difficult, this invention does not have such inconvenience.

In particular, in the present invention, a fitting groove is formed in the outer fixing metal fitting by folding back the outer end of the frame frame, and the protruding piece of the sash is fitted into this fitting groove to be attached to the sash. Unlike conventional types that are fixed by spot welding, etc., installation costs are low because they are installed simply by fitting, and on the other hand, they are not formed integrally with the sash, so they are not expensive. There is no waste of aluminum material, and the overall manufacturing cost is low.

Furthermore, according to this invention, since the outside fixing metal fittings are directly fixed by being pressed against the framework frame, they can be reliably integrated into the building body, and on the other hand,
Since the board of the inner fixing bracket is installed by fitting the groove of the board into the lip of the frame frame, it is not only easy to install the inner fixing bracket, but also the groove can be removed by tightening the bolts as described above. Although it is a simple installation structure with this type of fitting, it has the effect of being able to be installed securely. The effect of tightening can be achieved in one place.
