Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for attaching a sash frame that is applied when attaching a sash to an opening in the frame of a building made of reinforced concrete or steel-framed reinforced concrete.

[Conventional technology]

When equipping this type of building with a sash, the method of fitting and fixing the sash frame into the opening of the concrete frame is to set the sash frame correctly inside the formwork from the beginning and then pour the concrete for the frame. Apart from the so-called ``sash tip construction method,'' a sash frame is fitted into the opening of the building frame after concrete has been poured, and the positioning of the sash frame is adjusted using pieces of wood or the like. A rod-shaped connecting bar is bridged between the welding anchor planted on the inner circumferential surface of the sash frame and the sash-side anchor attached to the outer circumferential surface of the sash frame. The most common method is to weld both ends together by arc welding.

[Problem that the invention seeks to solve]

However, if the sash frame is attached and fixed to the opening of the building frame using the above-mentioned welding method, the heat during welding may cause distortion or deformation of the sash frame, which may impair the accuracy of the installation, so accurate construction is difficult. It is surprisingly difficult, and not only does it require that large-scale welding equipment be brought to the construction site and carried out by a person with knowledge and skills regarding welding, but it also takes too many man-hours to weld after positioning the sash frame. There are problems such as sparks scattering during welding work, so it is necessary to proceed with work while always paying attention to the surrounding conditions, and in some cases, it is necessary to take measures such as applying curing. Ta.

This invention was developed in order to address the above-mentioned problems, and its purpose is to significantly simplify the installation of a sash frame to the opening of a building frame without using any welding fixing means, and to To provide a method for attaching a sash frame which can extremely easily, reliably and safely attach and fix the sash frame to a predetermined position using a unique construction method using an adhesive as a bonding medium.

[Means for solving problems]

In order to achieve the above object, the method for attaching the sash frame according to the present invention includes:
Alternatively, after pouring, recesses are formed at appropriate intervals on the inner peripheral surface of the frame opening, and then a sash frame is fitted into the frame opening to adjust the positioning, and after that, each recess of the frame opening, The sash frame is fixed in a predetermined position by inserting both ends of the connecting bar across each concave hole of the sash-side anchor facing this recess, and using an adhesive at the insertion part of the connecting bar. shall be.

[Embodiments of the invention]

Hereinafter, embodiments of the present invention will be explained in detail with reference to the drawings. Fig. 1 shows an example of a mounting structure for a sash frame 2 fixed to a building frame opening 1 by applying the method of the present invention. When installing the sash frame according to the present invention, first, in the process of pouring concrete that will become the building frame W, ), as shown in Fig. 2, a small truncated cone-shaped object (a part of a separator for concrete formwork) generally called a "P-con" is used as a male mold 4, and this is inserted in the longitudinal direction of each template 3a. Concrete for the frame W is placed in a state where they are arranged and fixed at appropriate intervals along the middle part of the mold, and when the formwork is dismantled, the male mold 4 is removed from the concrete as shown in Figure 3,
An appropriate number of recesses 5 are formed in advance on the inner circumferential surface of the frame opening 1, or after forming the concrete frame opening 1, recesses 5 are formed at appropriate intervals on the inner circumferential surface of the frame structure opening 1 using a drill or the like. do.

Next, when fitting the sash frame 2, the fourth sash frame 2 is inserted into the frame opening 1 as in the conventional case.
After fitting as shown in the figure, insert an appropriate number of liners 6 and wedges 7 between the body opening 1 and the sash frame 2, and adjust the mounting position of the sash frame 2 by inserting and removing the wedges 7. .

After that, the sash frame 2 is immovably fixed, but in the case of the method of the present invention, when fixing the sash frame 2, unlike conventional fixing means such as welding,
Each recess 5 of the frame opening 1 described above is filled with a gel-like synthetic resin adhesive 8, such as an epoxy resin adhesive suitable for bonding iron, aluminum, concrete, etc., and the sash frame 2 is An anchor 9 having a shape as shown in FIG. 7 is provided on the outer peripheral surface.
This anchor 9 is placed in a position facing each of the recesses 5, and a connecting rod 10 made of, for example, round steel whose tip is bent into a key shape is interposed between both 5 and 9. and insert the proximal end of the connecting rod 10 into the adhesive-filled part of the recess 5 on the side of the frame opening 1,
The tip of the connecting bar 10 is attached to the anchor 9 on the sash side.
After inserting it into the recessed hole 9a of the anchor 9, the synthetic resin adhesive is applied to the gap between the tip of the connecting rod 10 and the recessed hole 9a of the anchor 9 using a spatula, and left for a certain period of time (epoxy resin Approximately 5 for adhesives
~6 hours) to harden the adhesive, and then
The sash frame 2 is immovably connected and fixed at a desired position as shown in FIG.

In the case of the above embodiment, the procedure for adhering the connecting bars 10 is as follows: (a) filling the recess 5 with adhesive, (b) inserting the connecting rod 10 into the recess 5 and the recess 9a, and (c) the recess 9.
An example is described in which the connecting reinforcement insertion part is applied in the order of applying adhesive to a.
After filling the inside with adhesive, both ends of the connecting rod 10 may be inserted into the adhesive filled part, and
Both ends of the connecting rod 10 may be first inserted into the recess 5 and the recessed hole 9a, and then adhesive may be applied to the insertion portion of the connecting rod 10 to secure the connecting rod 10 in place.

As described above, insert the sash frame 2 into the opening 1 of the frame.
After connecting and fixing the sash frame 2, the liner 6 and the wedge 7 that temporarily fixed the sash frame 2 are removed, and finally the first As shown in the diagram, mortar 11
All construction work is completed by applying the finishing coat.

〔Effect of the invention〕

As described above, when attaching sashes to the opening of the frame of a building made of reinforced concrete or steel-framed reinforced concrete, the method for attaching the sash frame according to the present invention is to install sashes at appropriate intervals on the inner peripheral surface of the opening of the concrete frame. After forming the recesses and then fitting the sash frame into the frame opening and adjusting the positioning, the sash frame is fitted over each recess in the frame opening and each recess in the sash side anchor facing the recess. It is sufficient to insert both ends of the connecting bars and fix the sash frame in a predetermined position by interposing an adhesive at the insertion part of the connecting bars, so welding means such as gas welding or arc welding is used to attach the sashes. There's no need.

As a result, there is no risk of warping or deforming the sash frame due to the heat during the welding process, which would impair installation accuracy, as was the case in the past. In addition, large-scale welding equipment must be brought to the construction site and skilled welding techniques are required. It goes without saying that ordinary construction workers can perform construction extremely easily, reliably, and quickly without the need for a person to install it.
This eliminates the need for curing work to prevent scattering of welding sparks, and can be expected to have excellent effects such as a significant reduction in the number of man-hours required for attaching the sash.
