Description

[Detailed description of the invention] (Field of application of the invention) This invention relates to an installation device for aluminum window frames for newly constructed houses, particularly ALC buildings (lightweight foam concrete buildings) and RC buildings (reinforced concrete buildings).

(Prior art) When installing an aluminum window frame into the window mounting opening of an ALC or RC building, conventionally, the reinforcing bars buried in the wall were exposed in advance around the window mounting opening. An anchor metal fitting attached to the outer peripheral edge of the window frame was fixed to this by welding means. This mounting structure has the following drawbacks.

In other words, since the above-mentioned two are connected by welding means, a skilled worker is required for welding work,
Naturally, production costs are high. In addition, since the reinforcing bars must be exposed in advance around the periphery of the window mounting opening, the location of the reinforcing bars must be determined accurately when assembling the ALC or RC wall. In the window mounting opening, the reinforcing bars must be bent to a precise position, which is quite a tedious task.

(Problems to be Solved by the Invention) Therefore, in this invention, there is no need to expose reinforcing bars around the opening for installing a window in a building, and it is possible to open an aluminum window frame without using welding. It is intended to be attached to the periphery of the part.

(Means for Solving the Problem) In order to solve the above problem, in this invention, an outdoor contact piece 2 and an indoor contact piece 3 are provided on the periphery of the window mounting opening 1. A first mounting hardware 4 is fixed to the window frame 5, and a first mounting hardware 4 is secured between the outdoor piece 18 protruding from the outdoor side periphery of the outer peripheral surface of the window frame 5 and the indoor piece 20 protruding from the indoor side periphery. 2 mounting hardware 7

On the other hand, the indoor piece 20 of the window frame 5 is supported in a pinched state by the indoor side piece 19 of the second mounting hardware 7 and the third mounting hardware 10. The frame 5 is adapted to be fixed to the first fitting 4.

Therefore, the screwing force of the bolt 11 screwed into the second fitting 7 and the third fitting 10 acts directly on the second fitting 7 and the first fitting 4, and As a result, the outdoor piece 18 of the window frame 5 is strongly supported by the outdoor contact piece 2 of the first mounting hardware 4, and the indoor piece 20 of the window frame 5 is supported by the second and third mounting hardware 7. , 10, and thereby the window frame 5 is firmly attached to the building frame 12 via the first mounting hardware 4. Since no tightening force is applied to the bolts 11 in the indoor/outdoor direction, the window frame 5 is not distorted even by excessive tightening force of the bolts 11.

(Example) Figures 1 and 2 show a window frame mounting device for an ALC building (lightweight foam concrete frame). An L-shaped edge metal fitting 13 which also serves as an L-shaped edge metal fitting 13 is fixed, and the above-mentioned first mounting fitting 4 is fixed to this edge fitting 13 along its entire area by bolts 14 or welding means 15. The first mounting hardware 4 is fixed to the frame hardware 13 after the frame hardware 13 is attached to the building frame 12 as part of the building frame assembly work that includes a lot of welding work, and in this process, the welding work is performed during fabrication. It will not cause a rise in costs. The first mounting hardware 4 consists of a mounting piece 16, the above-mentioned outdoor side abutment piece 2 that stands up in an L shape on its outdoor side, and the above-mentioned indoor side abutment piece 3 that also stands up in an L shape on its indoor side. It has a substantially U-shaped cross section, and the indoor side abutting piece 3 is further extended to L as appropriate.
It extends in a shape to form a positioning piece 17 for positioning the lower frame as described later.
Therefore, it is sufficient that the positioning piece 17 is provided in the lower frame part of FIG. 1, but the positioning piece 17 may also extend to the upper frame part of FIG. 1 and the side frame part of FIG. 2. This is because a member with a common shape is used over the entire area of the edge hardware. The process up to the installation of the first mounting hardware 4 is generally carried out by a building frame construction company that involves a lot of welding work, and then the window frame is assembled into an opening for window installation by a window frame installation company who is a so-called sash manufacturer. It will be incorporated into the department.

That is, on the outer periphery of a window frame 5 which has been pre-assembled into a four-circumferential frame shape by factory production, a substantially L-shaped second fitting 7 with an outdoor side piece 6 formed on the outside of the window is attached to the indoor side of the window frame 5.
