Description

  The present invention relates to a glass screen support structure using rib glass, and more particularly to a glass plate support structure using rib glass having a strength capable of reliably receiving a large wind load applied to a face plate glass.

  Conventionally, as a method of supporting a glass plate provided in an opening of a building, a case of supporting a sash frame with a steel rib (standing) has been generally adopted for a long time. Since the steel ribs obstructed the field of view, the feeling of opening and aesthetics was insufficient, but if only the sash frame was used, the wind pressure load from the out-of-plane direction of the face plate glass could not be supported.

  On the other hand, for the purpose of daylighting, aesthetics, etc., in the formation of a glass screen in which large glass plates are juxtaposed on the outer wall of a building to form a large opening, glass ribs are erected so as to be orthogonal to the vertical sides of the face plate glass plate. A glass rib construction method that adheres with a sealing material and supports a face glass plate has also been widely adopted.

  The glass rib construction method includes a glass rib construction method for supporting the glass plate by itself and a suspension rib construction method for supporting the glass plate by suspending the upper end of the glass plate, which can be selected depending on the height of the opening area of the face plate glass, the thickness of the glass plate, etc. Different. (Non-Patent Document 1).

  The method using the glass rib is widely adopted as a method of giving a transparent feeling to the glass opening, but supports a load in the out-of-plane direction such as a wind load applied to the face plate glass by the rib glass. Unstrengthened float glass, laminated glass, and tempered glass are used as the glass rib, and it is necessary to have sufficient rigidity to withstand the wind pressure load applied to the face plate glass.

  When float glass is used as the rib glass, the depth dimension (width dimension) of the glass rib must be increased, and furthermore, since the glass plate is sealed to the face plate glass only by the thickness width portion of the glass rib, sufficient adhesion to the end surface of the glass rib There was a problem that the cost could not be taken and a large adhesive strength could not be obtained.

  In order to solve the lack of strength of the float glass itself, the strength against wind load on the face plate glass, and the lack of adhesive strength between the end face of the rib glass and the face plate glass, the depth of the reinforced rib glass itself has been reduced to a small size in recent years as a reinforced rib glass, Attempts have been made to provide a pierced portion in the reinforced rib glass and attach a metal fitting to the pierced portion so that the fixing to the face plate glass can be fixed via an attachment metal fitting or the like instead of bonding.

  For example, as a prior art of Japanese Patent Laid-Open No. 10-231571, in FIG. 8 shown, a plurality of bolt holes are formed in the upper and lower portions of a plurality of rib glasses, and a pair of rib glasses arranged on the upper and lower sides are connected to each other. There is a description that the member is clamped with bolts and the connecting member is fixed to the face plate glass (Patent Document 1).

Furthermore, in Japanese Patent Application Laid-Open No. 2000-336804 filed by the present applicant, a glass plate in which rib glass is erected in a direction orthogonal to the vertical side of the face plate glass on one or both sides of a butted portion of face plate glass erected as an outer wall. In the support structure, a perforated portion is provided at the corner of the abutting side of the short ribbed tempered glasses arranged in parallel in the upper and lower rows, the perforated portions at the corners on the vertical side that are not in contact with the face plate glass, and the face plate Perforated parts at the corners on the vertical side that abuts the glass are connected by two types of long and short connection fittings, and the connection interval between the perforated parts on the side that abuts the face plate glass is the side that is separated from the face plate glass. The rib glass structure characterized by connecting the tempered glass for ribs smaller than the connection space | interval of parts was disclosed (patent document 2).
Japanese Patent Laid-Open No. 10-231571 JP 2000-336804 A Sheet glass general catalog, published by Central Glass Co., Ltd., printed on January 1, 2003 (page 196-strength of sheet glass under special conditions)

  In both Patent Document 1 and Patent Document 2, rib glass is tempered glass, and the tempered glass has a possibility of spontaneous breakage instead of increasing its strength by about 5 times compared to float glass. Then, there is a problem that the glass pieces are scattered.

  For this reason, when laminated glass bonded with PVB (polyvinyl butyral) film by combining tempered glass and float glass, it is possible to prevent the glass pieces from scattering at the time of breakage, but the manufacturing cost increases and the delivery time only increases. However, the problem of natural breakage of the tempered glass part still remained.

  Furthermore, in order to make a rib glass that can cope with a large wind load, a composite rib glass in which the rib glass is fixed to the sash frame that supports the face plate glass can be considered, but the problem is that the end face of the sash frame and the rib glass has low adhesive strength. There was a point.

  An object of the present invention is to have a strength capable of reliably receiving a large wind load applied to a face plate glass even if the rib has a small width, and to reduce natural breakage of the rib glass significantly.

  That is, the present invention is a support structure for supporting the wind load of the face plate glass by the rib glass erected so as to be orthogonal to the indoor surface of the face plate glass along the butting vertical side of the face plate glass standing as the outer wall. Point support in which the rib glass is double-strength rib glass, and is clamped and supported by bolt-shaped tightening members and nut-shaped members that are inserted through the perforated portions provided at predetermined intervals in the vertical direction near the vertical side of the rib glass on the face plate glass side. The metal plate and the mounting position of each point support metal plate provided on the rib glass and the metal plate attached in the vicinity of the corresponding vertical position of the face plate glass are connected by the connection metal plate to support the surface glass plate. It is the support structure of a glass plate.

  Alternatively, in the present invention, the rib glass is made of two double-strength rib glasses facing each other at a constant interval, and a perforated portion is provided at a position corresponding to each other in the vicinity of the vertical sides of the two double-strength rib glasses. By sandwiching one end of the connecting bracket, the perforated portions of the rib glass and the connecting bracket are aligned coaxially, and the two rib glasses are spaced apart by screwing the bolt-shaped tightening member and the nut-shaped member of the point support bracket. At the same time, the glass plate supporting structure is characterized in that the end of the connecting metal fitting connected to the support metal fitting attached to the face plate glass is connected and fixed.

  Alternatively, the present invention provides a female portion in the tip recessed portion of the projection of the bolt-shaped tightening member as a point support fitting for tightening and fixing the perforated portion provided near the vertical side of the rib glass and the perforated portion of the connecting member. Thickness of rib glass and connecting metal fittings so that the rib glass perforated portion is not overtightened when the screw portion is provided and the female screw portion and the bolt portion of the nut-like member are screwed to tighten the perforated portion of the rib glass. The above-mentioned glass plate support structure is characterized in that the total thickness of the glass plate is smaller than the length of the protrusion of the bolt-shaped fastening member.

  Alternatively, in the present invention, the butt longitudinal sides of the face plate glass are provided with gaskets in a sash frame erected so as to sandwich both front and back surfaces of the face plate glass along the vertical joints of the butt longitudinal sides of the face plate glasses. The front T-shaped vertical side portion of the connecting member fitted and fixed to the rib glass is slidably arranged in the vertical direction within the substantially C-shaped opening of the vertical frame, and the face plate glass and the rib glass The glass plate support structure according to any one of the above, wherein the glass plate support structure is provided.

  Alternatively, the present invention provides a tightening bolt in which a tightening bolt inserted from the outdoor surface side into a perforated portion provided in the vicinity of the corner of the butt vertical side of the face plate glasses and a tightening nut provided on the indoor surface side are screwed together. A perforated portion of the face plate glass is supported by an attaching member, and the fastening member is attached to the tip of each arm of a four-point support fitting such as an X-shape or an H-shape, and connected to the tip joint member of the joint fitting fixedly connected to the rib glass. The glass plate support structure according to any one of the above, wherein a face plate glass and a rib glass are disposed by screwing a central protrusion shaft portion of the four-point support metal fitting.

  Alternatively, the present invention is to tighten the bolts inserted from the outdoor surface side at predetermined intervals along the vertical joints of the vertical sides of the face plate glasses, and a tightening nut provided on the indoor surface side. The corner portion or the vertical side joint portion of the face plate glass is fastened and supported by the screwed fastening member, and the fastening member is screwed to the tip joint member of the connection fitting connected and fixed to the rib glass.

  By using double-strength glass as the rib glass, natural breakage can be greatly reduced, and a perforated portion can be easily provided at a desired position of the rib glass, and the strength can be doubled as compared with rib glass using float glass. In particular, in the case of a rib glass in which two double-strength glasses are arranged in parallel, the strength equivalent to that of tempered glass is obtained, and the probability of spontaneous breakage is low as in the case of tempered glass.

  Moreover, the plate width dimension of rib glass can be made small compared with the rib glass using float glass, the protrusion length to the indoor side of a glass rib decreases, and effective utilization of indoor space can be aimed at.

  Furthermore, the glass rib structure that supports the butted portion of the face plate glass with a sash frame and connects the sash frame and the point support fitting provided in the perforated portion of the double-strength glass makes it possible to It is now possible to have strength that can reliably receive the load.

  Alternatively, a four-point support fitting provided on the cross-shaped joint portion or a vertical joint portion provided with a bolt-like fastening fitting inserted into the four perforations of the face plate glass or in the vicinity of the vertical side for tightening support is provided. It is fixed to the face plate glass by fixing it by a so-called point support method (also referred to as DPG method or Dot Point Glazing method), which is fixedly attached to the point support bracket and connected via the four-point support bracket or the two-point support bracket. It has become possible to have a strength capable of reliably receiving such a large wind load.

  In this way, the rib glass 3 and the face plate glass 1 are connected via the connecting metal fitting 4 and the sash frame 2, so that the bonding strength is greater than when the rib glass 3 is bonded to the face plate glass 1 with a sealing material as in the prior art. Is very big. In addition, since the double-strength rib glass 3a is provided side by side as the rib glass 3, the same strength as that of the tempered glass can be obtained, and there is no fear of natural breakage or the like that easily occurs when the tempered glass is used.

  Furthermore, since it provided so that the middle position of the space | interval of the two double-strength glass 3a, 3a and the center of the joint width of the butt | matching vertical side part of face plate glass 1, 1 may correspond, It is preferable that the wind pressure load from the out-of-plane direction is evenly dispersed in the two double-strength glasses 3a and 3a, and no excessive force is applied to the rib glass 3.

[Embodiment 2]
The second embodiment shown in FIGS. 4 to 6 is an example in which only one double-strength rib glass 3 a is used as the rib glass 3.

  In the first embodiment, each perforated portion is fixed with the point support metal fitting so that the tip of the plate-like portion of the connecting metal fitting 4 is sandwiched between two double strength rib glasses. However, in the second embodiment, one double strength is used. The glass was sandwiched between a pair of L-shaped connection fittings 4. The connection fitting 4 of Example 2 was made into the L shape of the shape which isolate | separated the substantially T-shaped connection fitting of Example 1 into two.
