Description

  The present invention relates to a glass screen structure, and more particularly to a glass screen structure that supports a face glass by attaching a rib (stand) in the vicinity of a butt portion (joint portion) between two adjacent face glasses.

  In recent years, 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, as in a building employing a curtain wall. An example is a glass screen structure (for example, Patent Document 1) in which a rib glass is bonded and fixed to a joint portion of two adjacent face glasses with a silicone sealant in a direction orthogonal to the face glass.

On the other hand, in the glass screen structure disclosed in Patent Document 2, as shown in FIGS. 10 and 11, the rib member 2 supporting the two adjacent face glasses 1 and 1 is bonded to the bonding glass piece 3. It is comprised from the metal rib main body 4 holding the glass piece 3. FIG. The rib member 2 acts as if it is a metal rib member in appearance, and can utilize the rigidity of the metal, so that the entire width of the rib member 2 is made of a glass rib made of only a glass plate. Compared to the member, it can be reduced to a small size. Further, when the rib member 2 and the face glasses 1 and 1 are bonded by the sealing material 5, the bonding glass piece 3 and the face glasses 1 and 1 are bonded by the sealing material 5. The low adhesion reliability can be improved, and the rib member 2 and the face glasses 1 and 1 can be stably bonded. Thereby, according to the glass screen structure of patent document 2, even if it is the rib member 2 of a small width dimension, there exists an advantage that rigidity can be improved.

  However, in the glass screen structure of Patent Document 2, since the bonding glass piece 3 and the face glasses 1 and 1 are bonded at the joints of the face glasses 1 and 1, the face glasses 1 and 1 are in-plane due to an earthquake or the like. When subjected to interlayer deformation, for example, when one face glass 1 follows (escapes) in the upward direction indicated by an arrow A in FIG. 12, the force of the joint portion causes complicated deformation of the cross section of the sealing material 5. There was a problem that. In particular, not only the force in the direction of the arrow A but also a force inclined in that direction is applied to the a and b positions of the edge of the sealing material 5, so that the sealing material 5 is deformed in a complicated manner to be twisted. For this reason, high stresses are locally generated at locations a and b of the sealing material 5, which is not preferable. In addition, when the sealing material 5 is deformed in a complicated manner as described above, a rotational force indicated by an arrow B is applied to the bonding glass piece 3 due to the complicated behavior of the sealing material 5, and the corner portion of the bonding glass piece 3 is the rib body 4. Pressed against. For this reason, there is a problem that stress concentrates on the corner portion of the bonding glass piece 3 and the bonding glass piece 3 is easily damaged.

  The present invention has been made in view of such circumstances, and has a glass screen structure in which the rigidity is increased by a metal rib body and the adhesion is improved by bonding the glass piece for bonding and the face glass with a sealing material. An object of the present invention is to provide a glass screen structure capable of preventing a locally high stress from being generated in the sealing material due to the complicated behavior of the sealing material and preventing damage to the glass piece for bonding. To do.

In order to achieve the above object, the plurality of face glasses constituting the outer wall are bonded by a sealing material at a joint portion between the face glass and the adjacent face glass, and the direction orthogonal to the face glass is achieved. In the glass screen structure supported by the rib member disposed on the surface, the rib member includes a pair of bonding glass pieces disposed on both sides of the joint portion so as to face each adjacent face glass, and the pair of bonds. And a metal rib main body disposed along the joint portion, and the pair of glass pieces for bonding and the face glass opposed to the glass piece for bonding are independent of each other by a sealing material. and by adhering to support the face glass, the rib body, a pair of holding portions and corner housing portion of the bonding glass pieces are formed Consists of a part, characterized in that the while being separated from the prism portion and the pair of holding portions, the pair of holding portions are independently mounted for sliding movement in the vertical direction with respect to the prism portion A glass screen structure is provided.

  According to the first aspect of the present invention, each of the sealing materials for each face glass independently receives each behavior generated in two adjacent face glasses due to in-plane interlayer deformation caused by an earthquake or the like. The sealing material is not deformed in a complicated manner only by simple deformation of expansion and contraction, and the sealing material does not have a complicated behavior. As a result, according to the present invention, it is possible to prevent local high stress from being generated in the sealing material due to the complicated behavior of the sealing material, and to prevent damage to the glass piece for bonding. This also simplifies the design of the screen structure.

  The invention described in claim 2 is characterized in that, in claim 1, the glass piece for bonding is held movably in a predetermined direction with respect to the rib main body.

  According to the second aspect of the present invention, since the glass piece for bonding is held movably in a predetermined direction with respect to the rib main body, the glass piece for bonding moves following the behavior of the sealing material. Thereby, a deformation | transformation of a sealing material is suppressed, the stress which arises in a sealing material can further be reduced, and damage to the glass piece for adhesion | attachment can be prevented. In addition, the rib main body is supported by the housing of a building.

  The invention according to claim 3 is the glass for bonding according to claim 1 or 2, wherein the rib main body is configured to be divided by a plurality of members, and at least one of the plurality of members is separated. An opening for filling the sealing material is formed between the piece and the face glass.

  In order to fix the rib member to the face glass constructed at the construction site, it is necessary to easily place the sealing material on the bonding portion. Therefore, the invention according to claim 3 is configured such that the rib main body can be divided by a plurality of members, and at least one member among the plurality of members is separated, so that the gap between the glass piece for bonding and the face glass is separated. An opening for filling the sealant was formed. That is, in the procedure for placing the sealing material, first, at least one member among the plurality of members constituting the rib main body is separated from the rib main body, and the sealing material is filled between the bonding glass piece and the face glass. An opening is formed for the purpose. Next, a sealing material is placed between the glass piece for bonding and the face glass through the opening. Next, the separated member is fixed to the rib member so as to close the open portion.

  Therefore, according to the third aspect of the present invention, since the bonding location can be confirmed through the opening, the sealing material can be easily placed. Further, since the sealing material can be easily placed, the sealing material can be reliably placed in a shape close to the design value, and the strength can be stabilized.

  According to the glass screen structure of the present invention, the sealing material for each face glass independently receives each behavior generated in two adjacent face glasses due to in-plane interlayer deformation caused by an earthquake or the like. The sealing material does not deform in a complicated manner, and no complicated behavior occurs in the sealing material. As a result, according to the present invention, in the glass screen structure in which the rigidity is increased by the metal rib main body and the adhesion is improved by bonding the glass piece for bonding and the face glass with the sealing material, the sealing material is complicated. It is possible to prevent a locally high stress caused by the behavior from being generated in the sealing material and to prevent damage to the glass piece for bonding.

  Hereinafter, preferred embodiments of a glass screen structure according to the present invention will be described in detail with reference to the accompanying drawings.

Figure 1 is an enlarged perspective view of a glass screen structure 10, FIG. 2 is a plan view thereof. The glass screen structure 10 shown in these drawings arranges two rectangular face glasses 12, 12... Adjacent to each other in a building housing so as to be flush with each other, and upper and lower sides of the face glasses 12, 12. Is supported by a sash (not shown) which is a support frame. Then, a silicone-based sealing material 18 is placed on the joint 16 between the adjacent face glasses 12, 12, and the adjacent face glasses 12, 12 are bonded via their vertical edges, and the joint 16 In the vicinity, the rib member 20 is formed by bonding with the silicone-based sealing materials 22 and 24.

  The rib member 20 is bonded to a pair of bonding glass pieces 26 and 28 arranged to face each other of the adjacent face glasses 12 and 12 and to the face glasses 12 and 12 of the bonding glass pieces 26 and 28. A glass rib body 30 is provided that holds the glass pieces for adhesion 26 and 28 except for the portion to be disposed and is disposed along the joint portion 16. Then, the pair of glass pieces for bonding 26 and 28 and the face glasses 12 and 12 to which the glass pieces for bonding 26 and 28 face each other are bonded independently by silicone sealing materials 22 and 24. The rib main body 30 includes a holding portion 36 in which a housing portion 32 for the glass pieces 26 and 28 for bonding and flanges 34, 34... For preventing dropping are formed, and a rectangular column portion provided integrally with the holding portion 36. 38. The length of the rib member 20 in the height direction is formed to be substantially the same as the length of the face glass 12 in the height direction, and is supported by the building frame at the upper and lower ends. In addition, the glass pieces for adhesion 26 and 28 may be constituted by one member over the entire length of the rib member 20, or may be divided into a plurality of members.

  The operation of the glass screen structure 10 thus configured will be described.

  When one face glass 12 of the face glasses 12 and 12 follows the upward direction indicated by the arrow A in FIG. 4 due to in-plane interlayer deformation at the time of earthquake from the normal stable state shown in FIG. Only the sealing material 24 of the one face glass 12 receives the behavior generated in FIG. For this reason, the sealing material 24 is simply deformed upward and does not deform in a complicated manner, and the sealing material 24 does not have a complicated behavior. Further, the behavior generated in the other face glass 12 is received only by the sealing material 22 of the other face glass 12. For this reason, the sealing material 22 similarly undergoes only simple expansion and contraction and does not deform in a complicated manner. Therefore, no complicated behavior occurs in the sealing material 22. As described above, locally high stress is not generated in the sealing materials 22 and 24, and damage to the sealing materials 22 and 24 can be suppressed. Since the glass pieces for adhesion 26 and 28 are each independently subjected only to the force in the vertical direction from the sealing materials 22 and 24, damage to the glass pieces for adhesion 26 and 28 caused by receiving the force in the rotational direction is prevented. Can do.

By the way, the rib member 20 shown in FIGS. 1 and 2 integrally includes the holding portion 36 and the prism portion 38. However, in the glass screen structure of the embodiment, the prism portion 38 and the holding portion 36 are separated. and the holding portion 36 with respect to the prism portion 38, is attached movably in the up and down direction.

  According to this separation structure, when one face glass 12 follows the upward direction indicated by arrow A as shown in FIG. 5, the bonding glass piece 28 is pulled by the sealing material 24 and follows the upward direction. Therefore, the sealing material 24 is not deformed. Therefore, the stress generated in the sealing material 24 is further reduced, and damage to the sealing material 24 can be further prevented.

  6A and 6B show an example of a separation structure.

  6A, flanges 36A and 36A are formed on the back surface of the holding portion 36 so as to protrude from both sides and extend in the vertical direction. The prism portion 38 has flanges 36A and 36A, respectively. A housing portion 38A for housing 36A and flanges 38B and 38B for guiding the fungi 36A and 36A so as to be slidable in the vertical direction are formed. Thereby, the holding part 36 can move in the vertical direction with respect to the prismatic part 38.

  6B, a guide plate 36B extending in the vertical direction is formed on the back surface of the holding portion 36, and the guide plate 36B is slid in the vertical direction in the rectangular column portion 38. A guide plate 38C is formed to guide the plate. Thereby, the holding part 36 can move in the vertical direction with respect to the prismatic part 38.

  On the other hand, in the construction of the glass screen structure 10, in particular, until the placement (construction) of the sealing materials 22, 24, or during the placement, the bonding glass pieces 26, 28 are in the relationship with the gap with the storage portion 32. If it moves with respect to 36, the glass pieces 26 and 28 for adhesion | attachment will be damaged, and the problem that a placement operation cannot be implemented stably will arise. Further, when the glass pieces for adhesion 26 and 28 move during the curing of the sealing materials 22 and 24, there arises a problem that the adhesiveness is impaired.

  Therefore, in order to solve such a problem, an elastic body 40 such as rubber, plastic, felt or the like is laid in the gap between the storage portion 32 of the holding portion 36 and the glass pieces for adhesion 26, 28 as shown in FIG. The elastic body 40 is bonded to the holding portion 36 and the glass pieces 26 and 28 for bonding. Accordingly, inadvertent movement of the bonding glass pieces 26 and 28 with respect to the holding portion 36 can be prevented, and vibration can be absorbed, so that the bonding glass pieces 26 and 28 come into contact with the storage portion 32. It is also possible to prevent the bonding glass pieces 26 and 28 from being damaged due to the above.

  Further, as shown in FIG. 7, the holding portion 36 is configured to be divided by two members 36C and 36D, and the member 36D is separated from the member 36C, so that the bonding glass pieces 26 and 28 and the face glasses 12 and 12 are separated. The opening 42 for filling the sealing materials 22 and 24 can be widely formed. Thereby, since the adhesion location can be confirmed at the construction site, the sealing materials 22 and 24 can be easily placed. The separated member 36 </ b> D is fixed to the member 36 </ b> C with a bolt 44 so as to close the open portion 42 after the sealing materials 22 and 24 are placed. Further, since the sealing materials 22 and 24 can be easily placed, the sealing materials 22 and 24 can be reliably placed in a shape close to the design value, and the strength can be stabilized.

  In addition, in the glass screen structure 10 shown in FIGS. 1-7, although only the face glass 12 and the glass pieces 26 and 28 for adhesion | attachment were adhere | attached with the sealing materials 22 and 24, it is not limited to this. For example, as shown in FIG. 8, the flanges 34, 34 of the holding portion 36 are also bonded to the face glass 12, so that the bonding area by the sealing materials 22, 24 can be expanded. By expanding the bonding area in this way, the follow-up amount of the face glass 12 due to in-plane interlayer deformation increases, that is, the buffering force by the sealing materials 22 and 24 increases, so that a glass screen structure that is strong against earthquakes is obtained. .

  In FIG. 7, the holding portion 36 is configured to be split by the two members 36 </ b> C and 36 </ b> D to achieve the ease of placing the sealing materials 22 and 24, but is not limited to this split structure. For example, as shown in FIG. 9, the storage portion 32 of the holding portion 36 is formed so as to be inclined, so that a wide open portion 42 is inevitably formed on the side of the placement location. Therefore, it is possible to reduce the man-hours spent for placing the sealing materials 22 and 24.
