Description

  The present invention relates to a glass rib structure, and more particularly to a glass rib structure in a glass screen structure.

  In recent buildings, there are an increasing number of examples in which a large number of face glasses are supported without using a sash and an outer wall is constructed using these face glasses. An example thereof is a glass screen structure in which rib glass is attached to the joint portion of the adjacent face glass in the orthogonal direction (for example, Patent Document 1). The face glass and rib glass having a glass screen structure are bonded and fixed by a high-strength silicone sealant (structural sealant).

Moreover, the glass plate structure rib glass is usually made of float plate glass. Since this float plate glass can be manufactured without being restricted in size, it is effectively applied to a glass screen structure having a high height (for example, more than 10 m).
Japanese Patent Laid-Open No. 9-67883

  However, when float plate glass is used as the rib glass, it is necessary to increase the width of the rib glass in order to ensure strength when used under high wind pressure conditions. Therefore, when the rib glass is arranged on the indoor side with respect to the face glass, for example, the rib glass protrudes greatly to the indoor side, and in particular, the foot portion takes up space by the long rib glass, resulting in a dead space. (The same applies when the rib glass is disposed outside the room).

  On the other hand, laminated glass and tempered glass can be used as rib glass to cope with high wind pressure conditions, but in the case of laminated glass and tempered glass, there is a limit to the size that can be applied due to restrictions on manufacturing. there were.

  The present invention is intended to solve the problems of the conventional construction method described above, and in a glass screen structure using rib glass, the glass rib structure that can be used even under high wind pressure conditions without increasing the width of the rib glass, and the glass rib An object is to provide a glass screen structure to which the structure is applied.

In order to achieve the above object, the present invention is such that a face glass whose upper and lower sides are supported by a support frame is supported by a rib glass arranged in a direction orthogonal to the face glass at a joint portion with the adjacent face glass. In the glass screen structure, the rib glass is reinforced by a steel material attached over the entire length in the longitudinal direction of the rib glass, and the upper and lower ends of the steel material are fixed to the building side of the building, and the rib glass is silicone sealed to the face glass. The load bonded to the face glass and applied to the face glass is transmitted from the rib glass to the steel material through the silicone sealing material, and is transmitted from the steel material to the housing side so that the load is received by the housing. structural strength of Examples that the steel be borne And features.
According to the invention of claim 2, the vertical dimension of the steel material is longer than the vertical dimension of the rib glass, and the upper and lower end portions of the steel material protrude from the upper and lower end portions of the rib glass and are located on the housing side. It is preferably fixed.

  According to the first aspect of the present invention, since the steel material is attached over the entire length in the longitudinal direction of the rib glass and the rib glass is reinforced by the steel material, a glass rib structure that can be used even under high wind pressure conditions without increasing the width of the rib glass is provided. it can. As the rib glass, not only float glass but also laminated glass and tempered glass can be applied. Float plate glass has an advantage of not being restricted by size, and is suitable for a glass screen structure having a high height. On the other hand, the float glass can be drilled, but due to the strength problem of the drilled part, the connection structure with the steel material by tightening the bolt-like parts into the hole cannot be applied practically and bonded. A method of fixing a steel material with an agent is applied. It is conceivable to use steel materials directly without using glass as ribs, but silicone sealing materials that adhere and fix face glasses to each other and face glass to rib glass are unsuitable as adhesives with steel materials, so as ribs Glass is used and this rib glass is reinforced with steel. On the other hand, it is applicable if the glass that has been subjected to perforation processing is tempered glass.

The invention described in claim 3 is an invention in which tempered glass is applied as the rib glass, and the tempered glass has strength, and has been made paying attention to the fact that it can be used practically even if perforated. . That is, the rib glass made of tempered glass and the steel material were fixed by bolt-shaped parts inserted into the holes formed in the rib glass and the holes formed in the steel material. In addition, since tempered glass receives restrictions on a magnitude | size, when applying a glass screen structure with high height, it divides | segments into several pieces and each comprises these in a steel material, and comprises rib glass.

According to the invention described in claim 4 , the rib glass is a trapezoidal float plate glass in which the small facet in the short direction of the glass is processed diagonally, and the diagonally processed portion is obliquely processed through the buffer material. A taper member having the same angle as the portion is disposed, and the taper member is substantially the same thickness as the rib glass and has a through-hole into which a bolt-shaped part is inserted, or has a structure integrated with the bolt-shaped part, The rib glass and the steel material are fixed and integrated by tightening the shaped parts.

  Float plate glass that has been drilled is not applicable due to strength problems, but the rib glass made of float plate glass is supported by a taper member, and the bolt-shaped part that is tightened in the hole of this taper member or the taper member is integrated. The taper member and the steel material were fixed with bolt-shaped parts, and the rib glass was clamped and fixed with the steel materials arranged on both sides thereof. Moreover, even if it is a positive wind pressure and a negative wind pressure, it can receive the pressure with a steel material by supporting the diagonal process part of rib glass to a taper member.

According to invention of Claim 5 , since the upper and lower ends of steel materials were rigidly joined with the building frame, the moment added to rib glass and steel materials can be restrained small, and a member cross section can be made small.

According to the invention described in claim 6 , since the glass rib structure according to any one of claims 1, 2 , 3 , 4, or 5 is applied to the glass screen structure, the width of the entire rib glass is short. A glass screen structure having transparency with little dead space can be provided.

  According to the present invention, since a steel material is attached to the rib glass and the rib glass is reinforced by this steel material, a glass rib structure that can be used even under high wind pressure conditions without increasing the width of the rib glass can be provided.

  In addition, according to the present invention, it is possible to provide a glass screen structure having transparency with a short width of the entire rib glass and a small dead space.

  The preferred embodiments of the glass rib structure according to the present invention will be described below in detail with reference to the accompanying drawings.

  FIG. 1 is a perspective view of a main part of a glass screen structure 12 to which a glass rib structure 10 according to the first embodiment is applied as viewed from the room. In the glass screen structure 12 shown in the figure, rectangular face glasses 14, 14... Are arranged so as to be flush with each other in a window opening of a building, and upper and lower sides of the face glasses 14, 14. Are supported by the sashes 16, 16, and a long rib glass 20 is arranged in a direction orthogonal to the face glass 14 at the joint portion 18 of the face glasses 14, 14. The face glass 14, 14... And the rib glass 20 are bonded and fixed at the joint portion 18 with a high-strength silicone sealing material 22.

  A steel material (material: steel) 24 is attached to the rib glass 20 over its entire length in the longitudinal direction. The steel material 24 has upper and lower ends fixed to the building side of the building, and the rib glass 20 is reinforced to the steel material 24 by this configuration. By reinforcing the rib glass 20 in this way, a glass rib structure that can be used even under high wind pressure conditions without increasing the width of the rib glass 20 can be provided.

  FIG. 2 is a cross-sectional view taken along line 2-2 of FIG. As shown in FIG. 2, the steel material 24 is composed of two substantially L-shaped steel plates 26 and 26, so that the large area portion 26 </ b> A of the steel plate 26 covers the side surfaces 20 </ b> A and 20 </ b> A of the rib glass 20. The small area portion 26B is fixed to the rib glass 20 with an adhesive (not shown) so as to cover the indoor-side small face 20B of the rib glass 20. Further, a buffer material (material: silicone rubber, chloroprene rubber, plastic, aluminum alloy, etc.) 28 is provided between the rib glass 20 and the steel plate 26 to prevent the rib glass 20 from being damaged by the steel plate 26. The rib glass 20 with which the steel material 24 was integrated is comprised by affixing the inner surface of the buffer material 28 on the rib glass 20 with an adhesive agent, and adhering the steel plate 26 on the outer surface of the buffer material 28 with an adhesive agent.

  Therefore, according to the glass rib structure 10 of 1st Embodiment, it can be used also on high wind pressure conditions, without lengthening the width B (refer FIG. 1) of the whole rib glass. As the rib glass 20, laminated glass and tempered glass can be applied as well as the float glass. Since the float plate glass has an advantage that the size is not restricted, there is an advantage that even a high glass screen structure can be handled with a single rib glass 20 as shown in FIG.

  In the glass rib structure 10 of the first embodiment, the rib glass 20 is mainly bonded to the face glass 14, and the structural strength as a beam is mainly borne by the steel plates 26 and 26 on both sides. The load applied to the face glass 14 is transmitted from the rib glass 20 to the steel plates 26 and 26 through the silicone sealant 22, and is transmitted from the steel plates 26 and 26 to the housing, so that the load is received by the housing. .

  3 and 4 are a cross-sectional view and a vertical cross-sectional view, respectively, of a glass screen structure 32 to which the glass rib structure 30 of the second embodiment is applied.

  The rib glass 34 applied to the glass rib structure 30 is tempered glass. The tempered glass is produced by heating a plate glass produced in a float kiln or the like to the vicinity of the softening point with a heating furnace, air-cooling the glass with an air-cooling strengthening device, and forming a compressive stress layer on the surface. Applying tempered glass requires a heating process using a heating furnace and an air cooling tempering process using an air cooling tempering device in addition to the normal plate glass manufacturing process, and it goes without saying that the cost is higher than that of float sheet glass. In addition, since the size of the air-cooled tempering apparatus is limited, it is difficult to produce a large area tempered glass.

  In this way, tempered glass is more restricted in size compared to float glass, so a single tempered glass may not be applicable to a high glass screen structure. Since the glass manufacturing limit has been exceeded, the two rib glasses 34 and 34 are disposed along the joint portion 18 to provide the same function as the one rib glass 20 shown in FIG.

  The rib glass 34 has holes 36 processed at predetermined positions as shown in FIG. Further, corresponding to the hole 36, holes 38, 38... Are formed in the steel plates 26, 26. Bolts 40 are inserted into these holes 36 and 38 and fastened by nuts 42, thereby forming a glass rib structure 30 in which the rib glass 34 and the steel material 24 are integrated. Further, a buffer material (material: aluminum alloy, plastic, rubber, etc.) 44 is attached to the hole 36 of the rib glass 34, and the hole 36 is prevented from being damaged by the bolt 40. In addition, the component which fixes the rib glass 34 and the steel material 24 is not limited to the volt | bolt 40, What is necessary is just a component which can fasten the rib glass 34 and the steel material 24 if it is a bolt-shaped component.

  In the glass rib structure 30 of the second embodiment, the rib glass 34 is mainly bonded to the face glass 14, and the structural strength as a beam is mainly borne by the steel plates 26 and 26 on both sides. The load applied to the face glass 14 is transmitted to the rib glass 34 through the silicone sealant 22. In this case, in the glass rib structure 30 using the perforated tempered glass, the bolt 40 inserted into the hole 36 and the indoor side edge surface 34B of the rib glass 34 are transmitted to the steel plates 26 and 26 on both sides. The upper and lower ends of the steel plates 26 and 26 are usually joined to the housing side through pins, but both ends (one end may be sufficient) are connected to the ceiling surface 46 and the floor surface 48 as shown in FIG. Are rigidly joined (welded) to the structural bodies 50, 50 embedded in the housing. Reference numeral 52 denotes a rigid joint. The advantage of the rigid joint is that the bending moment generated at the center of the glass rib structure 30 can be reduced. By adopting the rigid connection, the bending moment at the rib central portion becomes about 1/3 as compared with the case of the pin connection, so that the glass rib structure 30 can be slimmed by the difference.

  5 and 6 are sectional views of a glass screen structure 62 to which the glass rib structure 60 of the third embodiment is applied. The rib glass 64 applied to the glass rib structure 60 is a float plate glass.

  The rib glass 64 is formed in a trapezoidal shape by processing an oblique face of the rib glass 64 in the short direction. In addition, the obliquely processed portion 65 of the rib glass 64 includes a tapered member 66 (material: aluminum alloy, plastic, rubber having high hardness (60 degrees or more)) in which the obliquely processed portion 65 and the inclined surface 67 thereof have the same angle, The inclined surface 67 is arranged in contact with the obliquely processed portion 65. A buffer material (not shown) is attached to the inclined surface 67 of the taper member 66, and the buffer material prevents the obliquely processed portion 65 of the rib glass 64 from being damaged.

  The taper member 66 is formed to have substantially the same thickness as or less than the rib glass 64, and a through hole 68 of the bolt 40 is formed. Instead of the hole 68, the taper member 66 may be configured in a structure in which the bolt 40 is integrated. The bolt 40 is fastened to the flat steel plates 72 and 72 of the steel material 70 disposed on the rib glass 64 with nuts (not shown). Thereby, the glass rib structure 62 in which the rib glass 64 is held between the steel plates 72 and 72 is configured. Also, a spacer plate 76 having the same thickness as the rib glass 64 is fastened to the steel plates 72 and 72 by bolts 78 and nuts 80 on the indoor side edge surface 74 of the rib glass 64 so that the spacer plate 76 contacts the edge surface 74.

  In the glass rib structure 60 of FIGS. 5 and 6, similarly, the load applied to the face glass 14 is transmitted to the rib glass 64 through the silicone sealing material 22. The load in the case of positive wind pressure (wind pressure in the direction indicated by arrow A in FIG. 5) is transmitted from the rib glass 64 to the steel material 70 (that is, the steel plates 72 and 72 on both sides) via the spacer plate 76, and negative wind pressure (FIG. 5). In the case of the wind pressure in the direction indicated by the arrow B, the inclined surface 67 of the taper member 66 and the taper processing portion 65 of the rib glass 64 are fitted to each other, so that the steel material 70 (i.e. It is transmitted to the steel plates 72, 72) on both sides.

  The angle of the inclined surface 67 of the taper member 66 (= the angle of the taper processing portion 65 of the rib glass 64) is preferably 5 ° to 20 ° in order to receive the positive wind pressure and the negative wind pressure with the steel material 70 in a balanced manner.

The glass rib structure of the present invention was examined on the basis of actual architecture (wind pressure was set to about 3.2 × 10 ³ Pa).

  Since glass is excellent in durability for bonding to the silicone sealant 22, the method of bonding the face glass 14 and the rib glass 20 with the silicone sealant 22 is a very effective method.

  In this study, since the glass screen structure is used at the foot of a high-rise building, the wind pressure of the high rise is higher than that of the low rise. In the case of this examination example, since the height of the glass screen structure is more than 10 m, the tempered glass and the laminated glass cannot be handled because they exceed the manufacturing limit.

  Therefore, if it is a conventional method, a general float plate glass must be used. In the case of the rib glass 20 using the float plate glass (see FIG. 1), the rib glass 20 needs to have a width exceeding 80 cm in the strength calculation, so that a large dead space is generated.

  Therefore, when the glass rib structure 10 in which the rib glass 20 is reinforced with the steel material 26 is applied, the overall width of the rib glass 20 is 40 cm or less. Therefore, the dead space can be reduced to about half of the usual method. In the case of tempered glass or laminated glass as the rib glass, this can be dealt with by using a plurality of rib glasses 34, 34 as shown in FIG.

  When using a plurality of rib glasses 34 and 64, it is important to consider the workability as well as manufacturing limitations. Considering the workability, it is better to make it as large as possible, but even if it is divided into smaller parts, there is no problem in terms of performance.
