Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention relates to a method for attaching window frames to a concrete wall, and is concerned with damage to the window frames due to vibrations such as earthquakes, and damage to the filler filled between the window frames and the opening in the concrete wall. This provides a construction method that prevents rainwater from penetrating through cracks.

0002

[Prior Art] A conventional method for attaching window frames to a concrete wall is to loosely fit a window frame with protrusions fixed to its outer periphery by welding, etc. into an opening in a concrete wall, and then move the window frame within the opening. The installation position is determined by the above-mentioned method, and the protruding pieces are welded to the reinforcing bars exposed in the opening, the side of the steel frame, etc., and the space between the opening and the outer periphery of the window frame is filled with cement mortar. If strong vibrations such as these occur, the window frames may vibrate along with the concrete wall, damaging the glass plate fitted on the inner periphery, or causing cracks in the cement mortar, allowing rainwater to penetrate inside the concrete wall. be.

0003

[Problems to be Solved by the Invention] In view of the above, the present invention provides an elastic material made of silicone rubber or the like which has the function of absorbing vibrations at the outer periphery of window frames and being able to expand and contract even when strong vibrations occur in concrete walls. This problem is to be solved by developing a method of providing a pipe material in the center and pouring an undried elastic sealing material around the outer periphery of the pipe material, which is the object of the invention.

0004

[Means for Solving the Problems] The method of attaching window frames to a concrete wall of the present invention includes a first projecting piece fixed at several locations on the outer periphery, and the outer periphery or inner periphery of the tip of the first projecting piece. A window frame in which a second protruding piece that is freely overlapped with the second protruding piece is surrounded by a holding coil spring is fitted into an opening in a concrete wall, and the outer end of the second protruding piece is placed on the inner periphery of the opening or on the inner periphery. An elastic tube made of silicone rubber or the like is fixed to the exposed reinforcing bars or steel frame and installed in the space between the frame and the inner periphery of the opening, and an undried elastic seal is applied to the outer periphery of the elastic tube in the space. It is characterized by being filled with a sealing material, which meets the above-mentioned purpose, and has an inventive step in that it provides anti-vibration and water-resistant properties using a naturally solidified sealing material and an elastic tube material embedded in the sealing material. Examples of the present invention will now be described.

In this embodiment, the window frame 1 is made of aluminum and has a rectangular shape (hexagonal, circular, etc.), and projecting edges 3, 3 are protruded from each of the front and rear sides of the frame plate 2 around the four circumferences. 4 consecutive grooves 4
An iron piece 5 is fixed to each of the four circumferential frame plates 2 with screws, etc., a first projecting piece 6 is welded to each of the iron pieces 5 to protrude, and the tip 7 of the first projecting piece 6 is A second projecting piece 8 whose end portions overlap each other in a freely expandable manner is arranged on the outer or inner periphery, and both projecting pieces 6 and 8 are surrounded by a highly elastic holding coil spring 10. As shown in FIG. Either overlap them on the sides as shown in II of Fig. 3, or make the tip 7 a small diameter and the end 9 also have a small diameter, overlap them on the sides as shown in the figure, or make the tip 7 tubular,
In this embodiment, the end portion 9 is made into a thin rod that can be slidably fitted into the inner periphery of the tip 7.

11 is a concrete wall, and window frames 1
An opening 12 into which the holder is loosely fitted is provided. opening 12
Determine the installation position of the window frames 1 that are loosely fitted into the
The outer end of the projecting piece 8 is welded and fixed to the reinforcing bar or steel frame 13 exposed in the opening 12, and when the reinforcing bar or steel frame is not exposed or cannot be exposed, the opening 12 is fixed with mortar.
Fix it to the inner circumference of the The first protruding piece 6 and the second protruding piece 8 have tips 7
Since the space between the tip 7 and the end 9 is widened as shown in FIG. 2, if the space 14 between the opening 12 and the window frame 1 is expected to be large, for example, Add measures such as making the angle of the diagonal formation sharper and lengthening the overlap. The holding coil spring 10 has both ends in elastic contact with the inner periphery of the opening 12 and the frame plate 2 which is the outer periphery of the window frame 1 . An elastic tube 15 made of silicone rubber or the like is installed in the space 14 so that it does not come into contact with the window frames 1 and the inner periphery of the opening 12.
The portion of No. 5 that intersects with the holding coil spring 10 is formed into an arc shape that follows the outer periphery of the holding coil spring 10 and is joined (FIG. 4). The outer periphery of the holding coil spring 10 may be wrapped with a flexible material such as a resin film.

A frame member (not shown) is placed on the inner and outer sides of the space 14 to prevent filling from leaking, and the outer periphery of the elastic tube member 15 is filled with a sealing material 16 and allowed to harden naturally. Although a two-component polyurethane resin is used as the sealing material, other sealing materials such as a two-component silicone resin may also be used. Although the sealing material 16 may enter between the pitches of the holding coil spring 10 and adhere to the first protruding piece 6 and the second protruding piece 8, there is no problem in terms of operation, but it is desirable to prevent the sealing material from entering as much as possible.

Effects of the Invention The method of attaching window frames to a concrete wall of the present invention consists of a first projecting piece 6 fixed at several locations on the outer periphery, and an end 9 attached to the tip 7 of the first projecting piece 6 so as to be freely expandable and retractable. A window frame 1, which is surrounded by a holding coil spring 10 and a second projecting piece 8 overlapped on the outer or inner surface thereof, is fitted into an opening 12 of a concrete wall 11, and the outer end of the second projecting piece 8 is inserted into the opening. 12, or a reinforcing bar or steel frame 13 exposed on the inner periphery, and an elastic tube 15 made of silicone rubber or the like is installed in the space 14 between the frame 1 and the inner periphery of the opening 12, The space part 1
The outer periphery of the elastic tube material 15 of No. 4 is filled with a sealant 16, and after the sealant 16 hardens naturally, the opening 1
Window frames are elastically attached to the concrete wall 11 via the sealing material 16 elastically adhered to the inner periphery of the window frame 2,
Even if the concrete wall vibrates due to an earthquake or the like, the vibration is absorbed by the sealing material 16. An elastic tube 15 passes through the sealing material 16, and this deforms as shown in FIG. aids in the absorption of Further, the first protrusion 6 fixed to the window frame 1 and the second protrusion 8 fixed to the inner periphery of the opening 12 of the concrete wall 11 are different from each other at the tip 7.
Although the end portions 9 and 9 are simply overlapped in a telescopic manner, the overlapping is held inside the holding coil spring 10 whose both ends are in elastic contact with the window frames 1 and the opening 12, so that the window frames 1 and the opening 12 are It has the effect of being able to extend and contract freely and maintain continuity at all times or during severe vibrations by cooperating with the sealing action of the sealing material 16.
