Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a sash mounting structure for a building.

[Problems to be solved by conventional technology and inventions] In conventional buildings, window frames were firmly fixed to the building frame using bolts or other fasteners, which caused the building to become larger due to earthquakes, wind, etc. When shaking occurs, a problem arises in that excessive stress may be applied to the window frame and glass, causing damage to the window frame and glass.

An object of the present invention is to solve the above-mentioned problems and provide a sash mounting structure that prevents window frames and glass from being damaged in response to large shaking of buildings due to earthquakes and the like.

[Means to solve the problem]

In order to achieve the above object, the sash mounting structure of the present invention includes a displacement following sliding portion that connects the upper and lower frames of the sash window frame and the opening of the frame in which the window frame is provided in a manner that allows relative movement. are arranged between the upper and lower frames and the upper and lower sides of the opening, and a sash mounting structure in which a right-angled holding part is formed at each corner of the window frame, 30% to 70% of the generated interlayer displacement is absorbed by the amount of elastic deformation accompanying the elastic deformation of the window frame, and 70% to 30% is absorbed by the amount of sliding displacement of the sliding portion. .

The invention also includes a connecting member fixed to the frame and a connected member fixed to the upper frame or lower frame of the sash window frame, and further,
The distal ends of the connecting member and the connected member are overlapped with a sliding layer interposed between the distal ends, and one of the distal ends of the connecting member and the connected member is elongated in the longitudinal direction of the upper and lower frames. an elongated hole is formed in the other side, and an elongated elongated hole is formed in the direction orthogonal to the elongated hole on the other side, and fixing tools are inserted into both of the elongated holes, and the two members are connected so as to be relatively movable by the fixing tool. composition .

A displacement following sliding portion is provided between the upper and lower frames and the opening of the frame.

[Effect]

When interstory displacement occurs due to shaking of the building, a predetermined relative displacement occurs between the window frame and the building frame.

This displacement is caused by relative movement between the upper side or lower side of the frame opening and the window frame in the displacement following sliding section.
Further, the amount of interlayer displacement is absorbed by elastically deforming the portions of the window frame other than the corner portions, that is, the upper and lower frames and the middle portions of the left and right verticals.

When a relative displacement occurs between the building frame and the window frame, in the displacement following sliding part, one of the connecting members and the connected member is held in an overlapping state with the leading ends of the connecting member and the connected member mutually overlapped. The leading end moves relative to the other leading end so as to slide in the longitudinal direction of the upper and lower frames or in a direction orthogonal thereto.

Unlike the case of the displacement tracking sliding part S on the upper frame 2 side,
In the displacement following sliding part S on the lower frame 3 side, the third
As shown in the figure, a level adjustment member 42 is disposed at the center of the left and right fixing tools 38, 38. Specifically, as shown in FIG. 8, the level adjustment member 42 is made of a bolt or the like, and is provided in a through hole 43 provided in a predetermined portion of the lower frame 3 and in a proximal end portion 37 of the connected member 8. It is inserted into or screwed into the adjustment screw hole 44, and the lower end is connected to the material 4.
It is in contact with 5. Reference numeral 46 designates a fixing nut, and the adjusting member 42 is rotated through a hexagonal hole 47 in the head thereof to adjust the levelness of the sash window frame 1, and then the nut 46 is tightened and fixed.

This adjustment work is done before attaching and sewing the edge of the presser foot 23.

The level adjustment member 42 has a sliding portion S on the lower frame 3 side.
・In the left and right vertical frames], installed in two places near 5.16 &J
It will be done. After this adjustment, the base end portions 35 of the connecting members 5 are fixed to the frame 4 via the fixing tools 36.

Among the displacement following sliding parts S..., only the central sliding part S on the lower frame 3 side is fixed (see FIG. 2). That is, as shown by the imaginary line 49 in FIG.
Form a joint. Therefore, by providing the joint portion 49, the upper frame 2 and the upper side 53 of the opening 14 are set to be movable relative to each other than between the lower frame 3 and the lower side 54 of the opening 14.

In addition, in FIG. 1, the concave groove 55 on the upper surface of the upper frame 2 serves as a rainwater catchment in the event that rainwater or the like infiltrates. The same applies to the drainage groove 56 provided in the lower side 54 of the opening 14.

Therefore, in FIG. 1, right angle holding portions 7 are formed at each corner portion 6 of the window frame 1,
In the case of turning, the corner portions 6 are reinforced using the corner connecting shapes 50.

Specifically, as shown in the fourth article, for example, an L-shaped member 50 is attached to each end of the upper frame 2 and the right vertical frame 16, which are finished at an angle of 45 degrees.
After fitting both ends of the upper frame 2. with caulking 51, etc. The L-shaped member 50 is fixed to the right vertical frame 16, and by increasing the rigidity of the corner part 6, when the window frame 1 is elastically deformed, the corner part 6... This is to keep the angle R at right angle.

In addition, in order to fix the L-shaped member 50, it is preferable to use welding as shown in FIGS. 5 and 6, and 52 is a welded joint. Alternatively, screws or the like may be used.

In FIG. 2, when the building sways in the direction of the arrow, the building frame 4 undergoes glabellar displacement in the same direction as shown by the imaginary line, and this magnitude is expressed as an interstory displacement measure. Here, the interlayer displacement gauge is P that forms the lower side 54 of the opening 14.
This corresponds to the relative displacement of the PC plate 33 forming the upper side 53 of the opening 14 with respect to the C plate 33. In addition, 57.57
indicates the floors of the upper and lower floors of the building. As shown in FIG. 10, when the window frame 1 undergoes a glabellar displacement in the direction of the arrow, first, the connection fixed to the upper side 53 of the opening 14 in the displacement following sliding portion S... The member 5 moves in the direction of the arrow by a predetermined sliding displacement amount L2. At the same time, one of the mutually contacting slide layers 13.13 moves together with the connecting member 5 while sliding with respect to the other slide layer 13. In addition, the displacement tracking sliding part S of the three lower frames...
- A slight relative movement occurs between the connecting member 5 and the connected member 8. In this way, in the displacement follow-up sliding portion S of the two upper frames... The sliding displacement amount L2 corresponds to the distance until the fixing tool 12 comes into contact with the end of the elongated hole IO of the connecting member 5.

If the interlayer displacement exceeds the amount of sliding displacement L2, as shown in FIG. The frame 1 receives a force in the direction of the arrow and elastically deforms as shown by the imaginary line.

In this case, the corner parts 6... of the window frame 1 have high rigidity due to the provision of the right angle holding parts 7..., so the upper and lower frames 2, 3 and the left and right vertical frames 15, 16 are Only the corner portions 6 are deformed, and the corner portions 6 are always held at right angles R. Then, based on the elastic deformation amount L1 due to the elastic deformation of the window frame 1 in the direction of the arrow at this time and the sliding displacement position L2,
The amount of interlayer displacement will be absorbed in each case. In this case, 30% to 70% of the relative movement in the direction of the arrow
Preferably, 60% is the amount of elastic deformation accompanying elastic deformation of the window frame 1, and 70% to 30%, preferably 40% is the amount of sliding displacement L of the sliding displacement in the displacement tracking sliding portion S...
2, it will be absorbed in its share.

Unlike the case of the above embodiment, as shown in FIG. It is also preferable to form.

In the above embodiment, since the stainless steel ring 41 is inserted into the long hole 10 of the connecting member 5, when the fixing tool 12 inserted into the ring 41 moves relatively within the long hole 10, the ring 41 and the fixing tool 12 do not mesh with each other. In other words, the ring 41 rotates and connects the connecting member 5 and the fixing member 1.
2 is reduced, and relative movement between the connecting member 5 and the connected member 8 is performed smoothly.

〔Effect of the invention〕

Since the present invention is configured as described above, it produces the effects described below.

■ When a building shakes due to an earthquake, wind, etc., this shaking can be absorbed and the window frame 1 and glass plate 24 can be prevented from being damaged.

■ Since the interlayer displacement that occurs in the opening 14 is absorbed by both the displacement in the displacement following sliding part S... and the elastic displacement in the window frame 1, excessive stress is not applied to a part of the window frame 1. There is no permanent distortion in the window frame 1.

■ Since the right angle holding portions 7 are formed at each corner portion 6 of the window frame 1, the displacement of the window frame 1 caused by the shaking of the building can be prevented by controlling the vertical frames 2 and 3 and the left and right vertical frames 15° and 16. It can be generated in the middle.

■ In the displacement following sliding part S..., the connecting member 5
and the connected member 8 are connected through the slide layer 13 so that they can move smoothly relative to each other, so when the building shakes, the displacement following sliding portion S... The window frame 1 then undergoes elastic deformation. Therefore, after a part of the amount of interlayer displacement I occurring in the frame opening 14 is absorbed, the rest is absorbed into the window frame 1, so that it is possible to prevent excessive stress from being applied to the window frame 1. .
