Description

[Detailed explanation of the invention] a. Purpose of the invention (industrial application field) The device for attaching a sash frame to the opening of a building wall made of concrete panels according to this invention is applicable to lightweight aerated concrete panels (ALC boards) and other It is used to attach metal sash frames to openings in building walls made of precast concrete panels (PC boards) without using welding methods.

(Conventional technology) In recent years, lightweight aerated concrete panels, which have excellent fire resistance and heat insulation properties, have come to be used not only for buildings but also for general housing. It became necessary to install an aluminum sash frame inside the opening in the concrete panel building wall.

For this reason, sash frames have conventionally been attached to the inside of openings in concrete panel building walls using various means and structures.

Three examples are shown in Figures 5 to 7. First, in the first example shown in Figure 5, the corners of the concrete panel 1 are completely removed to prevent them from being damaged. A sash frame 4 (both figures 5 to 7 show the lower frame, but the upper frame , the same applies to the case of a vertical frame.) A bracket 5 fitted to the concrete panel 1 is welded, and a sash frame 4 is attached to the reinforcing bar 2 of the concrete panel 1 via the angle material 3 and the bracket 5.

In addition, in the second example shown in FIG. 6, a bracket 5 is welded directly to the end of the reinforcing bar 2 exposed on the end face of the concrete panel 1, and the bracket 5 is attached to the reinforcing bar 2.
The sash frame 4 is attached via the sash frame 4.

Furthermore, if the reinforcing bars 2 to which the brackets 4 are to be welded are not exposed on the end face of the concrete panel 1, as in the third example shown in FIG. The sash frame 4 is attached to the concrete panel 1 by fixing a steel plate 7 and welding a connecting piece 8 fixed to the sash frame 4 to the steel plate 7.

(Problem that the invention aims to solve) However, the above-mentioned conventional methods and structures for attaching sash frames to openings in building walls made of concrete panels require welding work at the construction site. Become.

In the structure shown in Fig. 5, the work of welding the angle members 3 to the reinforcing bars 2 is not a particular problem as it is done in the construction factory of the concrete panel 1, but it is not necessary to weld the brackets 5 to the reinforcing bars 2 or the angle members 3. The work of welding and welding the connecting piece 8 to the steel plate 7 must be performed on site, and is a work that is disliked by workers. In other words, even in buildings using concrete panels, the steel frames are assembled on site by simply tightening bolts, and almost no welding is required. It is difficult to expect high-quality welding because it is a work that is difficult to perform.

The device of the present invention for attaching a sash frame to an opening in the wall of a building made of concrete panels eliminates the above-mentioned inconveniences and allows the sash frame to be attached to the opening without using welding means. be.
