Description

TECHNICAL FIELD The present invention relates to a sash mounting structure for a building.

[Problems to be Solved by Conventional Techniques and Inventions]

In conventional buildings, etc., the window frame is firmly fixed to the body of the building with fasteners such as bolts, so if the building shakes significantly due to an earthquake or wind, the window frame cannot be followed. There has been a problem that excessive stress is applied to the glass and the glass and the glass may be damaged.

An object of the present invention is to solve the above problems and to provide a sash mounting structure in which a window frame or glass is not damaged in response to a large shaking of a building due to an earthquake or the like.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, in the sash mounting structure of the present invention, a displacement follower sliding portion that connects the upper and lower frames of the sash window frame and the opening of the frame body provided with the window frame so as to be relatively movable. Is a sash mounting structure in which a right-angled holding portion is formed between each of the upper and lower frames and the upper and lower sides of the opening, and each corner of the window frame is formed in the opening. 30% to 70% of the generated interlayer displacement is shared and absorbed by the elastic deformation amount _{1 due} to the elastic deformation of the window frame, and 70% to 30% by the sliding displacement amount of the sliding portion in the sliding portion. .

In addition, a connecting member fixed to the frame, and a connected member fixed to the upper frame or the lower frame of the sash window frame, further,
The leading end portions of the connecting member and the connected member are superposed with a slide layer interposed between the leading end portions, and one end of the connecting member and the connected member is elongated in the longitudinal direction of the upper and lower frames. -Shaped elongated hole is formed, and on the other side, an elongated elongated hole is formed in a direction orthogonal to the elongated hole, and fasteners are inserted into both the elongated holes to connect the both members by the fasteners so as to be relatively movable. The displacement follow-up sliding portion thus constructed is provided between the upper and lower frames and the skeleton opening.

[Action]

When the interlayer displacement occurs due to the shaking of the building, the window frame causes a predetermined relative displacement between the window frame and the building frame. This displacement is
In the displacement-following sliding portion, the upper or lower side of the frame opening and the window frame move relative to each other, so that the parts other than the corners of the window frame, that is, the middle parts of the upper and lower frames and the left and right vertical frames are elastic. By deforming, the amount of interlayer displacement is absorbed.

When relative displacement occurs between the building frame and the window frame, in the displacement follow-up sliding part, one end of the connecting member and the connected member is held in an overlapping state with each other. The tip part slides relative to the other tip part in a sliding manner in the longitudinal direction of the upper and lower frames or in the direction orthogonal thereto.

In FIG. 2, when a layer displacement in the same direction D occurs on the skeleton 4 as shown by an imaginary line due to the shaking of the building in the direction D, this amount is represented by the layer displacement amount L. Here, the interlayer displacement amount L is the PC plate forming the lower side portion 54 of the opening 14.
This corresponds to the relative displacement of the PC plate 33 forming the upper side portion 53 of the opening 14 with respect to 33. 57 and 57 are floors of the upper and lower floors of the building. As shown in FIG. 10, the window frame 1
When is subjected to interlayer displacement in the direction of arrow D, first, in the displacement follow-up sliding portion S, the connecting member 5 fixed to the upper side portion 53 of the opening 14 has a predetermined sliding displacement L in the direction of arrow D. Move at ₂ . At this time, at the same time, one of the slide layers 13 and 13 contacting each other, together with the connecting member 5, is the other slide layer.
It moves while sliding with respect to 13. In addition, in the displacement follow-up sliding portion S on the lower frame 3 side, the connecting member 5 and the connected member 8 are connected.
There is a slight relative movement between them. As described above, in the displacement follow-up sliding portion S on the side of the upper frame 2, the slip generated between the connecting member 5 and the connected member 8 and by extension between the upper side 53 of the opening 14 and the upper frame 2 is blocked. The sliding displacement amount L ₂ corresponds to the distance until the fixing tool 12 contacts the end of the elongated hole 10 of the connecting member 5. When the inter-layer displacement amount L exceeds the amount of this sliding displacement amount L ₂ , as shown in FIG.
The window frame 1 receives a force in the direction D of the arrow via the upper side portion 53, the upper frame 2 of the window frame 1, and the like, and elastically deforms like a virtual line. In this case, the corner portions 6 of the window frame 1 have a large rigidity due to the provision of the right-angled holding portions 7, so that the upper and lower frames 2 and 3 and the left and right vertical frames 15 and 16 are deformed only in the middle portions thereof. , Corner portions 6 are always held at a right angle R. Then, the interlayer displacement amount L is absorbed by each of the elastic deformation amount L ₁ due to the elastic deformation of the window frame 1 in the arrow direction D and the sliding displacement amount L _{2 at} this time. In this case, of the relative movement amount L in the arrow direction D, 30% to 70%, preferably 60%, is displaced by 70% to 30%, preferably 40% by the elastic deformation amount L ₁ accompanying the elastic deformation of the window frame 1. The sliding displacement amount L ₂ of the sliding displacement in the following sliding portions S ... is shared and absorbed.

Unlike the case of the above embodiment, as shown in FIG. 11, the elongated hole 10 of the connecting member 5 is formed in the orthogonal direction B, and the elongated hole 11 of the connected member 8 is formed in the longitudinal direction A of the upper and lower frames 2, 3. It is also preferable to form.

In the above-mentioned embodiment, since the stainless steel ring 41 is inserted into the elongated hole 10 of the connecting member 5, when the fastener 12 inserted in the ring 41 moves relatively in the elongated hole 10, the ring 41
And the fastener 12 do not mesh with each other. That is, the ring 41 rotates to reduce the friction between the connecting member 5 and the fixture 12, and the relative movement between the connecting member 5 and the connected member 8 is smoothly performed.

[Advantages of the Invention] Since the present invention is configured as described above, it has the effects described below.

When the building shakes due to an earthquake, wind, or the like, it is possible to absorb this shaking and prevent the window frame 1 and the glass plate 24 from being damaged.

Since the interlayer displacement amount L generated in the opening 14 is absorbed and shared by both the displacement in the displacement follow-up sliding portions S ... and the elastic displacement in the window frame 1, an excessive stress may be applied to a part of the window frame 1. Nonetheless, permanent distortion does not occur in the window frame 1.

Right-angled holding portion 7 at each corner portion 6 in the window frame 1
As a result, the displacement of the window frame 1 due to the shaking of the building can be generated in the middle of the upper and lower frames 2 and 3 and the left and right vertical frames 15 and 16.

In the displacement follow-up sliding portion S, the connecting member 5 and the connected member 8 are connected via the slide layer 13 so as to be relatively movable relative to each other, so that when the building shakes,
First, a sliding displacement occurs in the displacement follow-up sliding portions S ... And then an elastic deformation occurs in the window frame 1. Therefore, after a part of the interlayer displacement amount L generated in the frame opening 14 is absorbed and the rest is absorbed by the window frame 1, it is possible to prevent an excessive stress from being applied to the window frame 1.
