Description

[Detailed description of the invention] (1) Industrial application field The present invention relates to a support structure for plate glass.

(2) Prior art Conventionally, a support frame installed at one of the upper and lower edges of an opening in a building is used to attach a support frame to one side of a face glass plate (usually referred to as a face plate) established in the opening in a direction perpendicular to it. A support glass plate (commonly referred to as a glass stabilizer) is similarly established to support the face glass plate at the leading edge of the support glass plate, and to support the face glass plate at the front edge of the support glass plate, and to support the face glass plate near the other of the upper and lower edges of the opening. An elastic surface support gasket is installed along the glass plate in pressure contact with both sides thereof, and an elastic surface support gasket is installed in pressure contact only with the rear edge of the support glass plate in a direction perpendicular to the support glass plate and at approximately the same height as the surface support gasket. A gasket for edge support is installed, and the roof moves up and down due to the wind.
The support structure for plate glass, in which both glass plates slide inside this gasket to maintain watertightness and airtightness when the floor surface moves up and down due to an earthquake, etc., is generally known, and this construction method has been used. This is usually called the glass stabilizer method.

By the way, in such a support structure, the horizontal load acting on the face glass plate acts as an evenly distributed load over the wide other surface of the face glass plate, so that it acts on each part of the face glass plate. The load is relatively small, and the face glass plate is held stably, but on the other hand, the support glass plate supports the face glass plate at its narrow front edge, and the load is concentrated there. , the edge support gasket supporting the rear end will be subjected to a large concentrated load. Therefore, the edge support gasket cannot stably hold the supporting glass plate unless it generates a larger reaction force than the surface support gasket, but both gaskets have exactly the same structure and are made of the same material. However, it was difficult to stably hold the supporting glass plate, and the glass plate could be damaged.

In addition, in the conventional structure as described above, the surface support gasket and the edge support gasket are fixed at fixed positions, so if there is a warpage of the glass plate or an error in the straightness of the building, However, there was a drawback that the degree of pressure contact with the glass plate was uneven, and there was also a risk of damaging the glass plate.

(3) Purpose The purpose of the present invention is to eliminate the drawbacks of the conventional plate glass support structure as described above, and to reduce the reaction force of both gaskets by making the edge support gasket have a larger reaction force than the surface support gasket. It is possible to maintain a good balance between the two gaskets, and to make the degree of contact between the glass plate and both gaskets the same in each part.
An object of the present invention is to provide a support structure for a glass plate that can prevent the glass plate from being damaged.

(4) Configuration In order to achieve the above-mentioned object, the present invention is such that, in the support structure for plate glass as described above, the edge support gasket has a larger reaction force than the surface support gasket, and furthermore, the edge support gasket has a larger reaction force than the surface support gasket. The degree of pressure of the support gasket and the edge support gasket against the glass plate can be adjusted.

Embodiments of the present invention will be described below with reference to the drawings.

A first embodiment is shown in FIGS. 1 to 7, which is a floor-supported type, in which 1 is a face glass plate;
2 is a support glass plate, and these glass plates 1 and 2 are installed on a setting block 7 installed at the bottom of a groove of support frames 4 and 4' provided on a floor 27 corresponding to the lower edge of the opening. The glass plate 2 is fixed to the support frames 4 and 4' by a back-up material 6 and an elastic sealant 5 filled in the groove at the upper part thereof, and a silicone sealant is applied to the contact portion of the glass plate 2 to the glass plate 1. 3 is filled.

A bracket 9 is arranged at the upper edge of the opening with the glass plates 1 and 2 in between, and this bracket 9 is attached to the building ceiling or frame 26 with mounting bolts 8, and a bolt support plate 11 is attached to the lower part of the bracket 9 with set bolts. 10, and an adjustment bolt 12 is screwed into a screw hole drilled therein.
The adjusting bolt 12 is set in a desired position on the bolt support plate 11 by a lock nut 13.

A gasket mounting member 14 extending horizontally along the glass surface is attached to the tip of the adjustment bolt 12, and inner and outer hollow portions 21, 22 are formed in the mounting member 14 along the longitudinal direction, and the bolt 12 is attached to its head. The head portion is located within the hollow portion 22 of the mounting member 14, and its neck portion is configured to rotate within a through hole provided in the side plate of the mounting member 14. Further, the hollow portion 21 communicates with the outside through a slot 23 bored along the longitudinal direction. The surface supporting gasket 15 is supported by this hollow portion 21.

This gasket 15 is approximately H-shaped as shown in FIG.
The connecting portion 25 is located in the slot 23, and the outer upright portion has an arc-shaped reaction force portion 19 at the upper part and a downward lip-shaped seal portion 20 at the lower portion, so that the reaction force can be reduced. The lower end of the portion 19 is open and the hollow portion 17 communicates with the outside, but this may be closed. Note that the surfaces of the reaction force section 19 and the seal section 20 are preferably subjected to a surface treatment such as electric flocking or Teflon treatment to make them slippery.

An edge support gasket 16 is installed facing the rear edge of the support glass plate 2 in a direction perpendicular to it and having a mechanism similar to that of the surface support gasket 15, and is installed at almost the same height. As shown in FIG. 7, a reaction member 18 as shown in FIG. 8 is fitted into the hollow portion 17 of the gasket 15.

In this case, gaskets 15 and 16 have a partially identical structure, and gasket 15 can be used as is for both, resulting in a significant reduction in manufacturing costs. However, there is no problem even if it has a different structure in advance.

In the case of the above-mentioned device, the surface support gasket 15 has elasticity like the conventional gasket, but the edge support gasket 16 has elasticity.
is filled with reaction material 18,
Since it does not have a hollow part 17, the reaction force is large, and as a result, it can sufficiently resist a large concentrated load applied to the support glass plate 2, and both gaskets 15 and 16
The reaction forces are balanced and support both glass plates 1 and 2 stably.

Furthermore, if the glass warps or there is an error in the straightness of the building, glass plates 1 and 2 and gasket 1
If there is a deviation in the relative position between the glass plates 1, 2 and the gaskets 15, 16, causing a deviation in the supporting reaction force or deviation in the degree of pressure contact between the glass plates 1, 2 and the gaskets 15, 16, After loosening the lock nuts 13, adjust the adjustment bolts 12 at the locations to adjust the positions of the gaskets 15 and 16.
The relative position between the gasket 15 and the gasket 15 and 16 will be corrected.

FIG. 9 shows a part of the second embodiment.
This differs from the first embodiment only in that it is a ceiling hanging type, and is completely the same in other respects, so only the different parts will be explained, and the other parts will be given the same reference numerals. Therefore, the explanation thereof will be omitted.

The upper edges of the glass plates 1 and 2 are clamped and suspended between a pair of clamping plates 30 and 31 which are suspended by suspension bolts 29 from a beam 28 attached to a building ceiling or a frame 26, and the support frames 4, 4' is fixed to brackets 32, 32' suspended from the ceiling 26.

Contrary to the first embodiment, the gaskets 15 and 16 have the seal portion 20 at the top and the reaction force portion 19 at the bottom.

In each of the above embodiments, a structure in which the support glass plate 2 is provided on only one side of the face glass plate 1 is shown, but a structure in which the support glass plate 2 is provided on both sides of the face glass plate 1 is also applicable. Of course, it can also be applied to.

In addition, each embodiment merely shows a preferable example, and it goes without saying that even if the structure differs from these embodiments, it may be an appropriate structure as long as it falls within the scope of the claims. do not have.

(5) Effects Since the present invention is as described above, the reaction force generated by the surface support gasket that supports the face glass plate along the horizontal direction and the rear force of the support glass plate that supports the face glass plate at its front edge are To be able to stably hold both glass plates and prevent breakage of the glass plates by receiving horizontal loads such as wind pressure acting on the face glass plate due to the large reaction force caused by the surface support gasket that presses against the edge. This has the effect of being able to.

Furthermore, in addition to the above, this invention makes it possible to adjust the degree of pressure contact of the surface support gasket and the edge support gasket with respect to the glass plate, so even if the glass plate is warped or there is an error in the straightness of the building. However, by adjusting the degree of pressure contact between both gaskets accordingly, the degree of pressure contact between the two gaskets is always optimized, and both horizontal and vertical loads applied to the glass plate can be absorbed by both gaskets, further preventing damage to the glass plate. It also has this effect.
