Abstract

PROBLEM TO BE SOLVED: To provide an earthquake-resistant glass screen structure and a glass screen method, contractible in a short construction period with a simple structure, in the present invention.SOLUTION: According to a glass screen structure 10 of the present invention, a sealant 20 installed in a central vicinity part 18A of a joint part 18, has sufficient tensile strength, shear strength and adhesive strength to force such as wind pressure acting in an out of plane direction of surface glass 14. When inter-layer displacement is caused in a skeleton 22 by an earthquake, even when a difference in a displacement quantity between the surface glass 14 and mullion glass 16 becomes large in an upper part and a lower part of the mullion glass 16, since the upper part and the lower part of the mullion glass 16 are a nonadhesive part of applying adhesion preventive processing by adhesion preventive processing means, the upper part and the lower part of the mullion glass 16 independently operate without being substantially restricted by the surface glass 14. That is, the nonadhesive part absorbs a difference in operation between the surface glass 14 and the mullion glass 16 when the inter-layer displacement is caused.

Description

  The present invention relates to a glass screen structure and a glass screen method.

  In recent years, many glass screen structures in which an opening of a building such as a building is constituted by a large glass screen have been constructed.

  The glass screen structure includes a surface glass and a vertical glass in which a plurality of glass plates are arranged flush or have a predetermined angle. The vertical glass is disposed along the joint portion located in the vertical direction of the glass plate adjacent to the surface glass and is bonded to the surface glass in a predetermined angular direction by a sealing material placed along the joint portion. The As the sealing material, a high modulus sealing material having sufficient tensile strength, shear strength, and adhesive strength against a force such as wind pressure acting in the out-of-plane direction of the surface glass is used.

  In addition, the lower end part of the surface glass and the vertical glass is fixed to the lower fixed frame fixed to the housing, and the upper end part is fixed to the upper fixed frame.

  In the glass screen structure, the displacement of the face glass and the vertical glass when an interlayer displacement occurs in the housing due to an earthquake or the like will be described with reference to a schematic diagram shown in FIG.

  Reference numeral 1 in FIG. 7 is a glass plate, reference numeral 2 is a face glass, and a broken line indicated by a reference numeral 3 is vertical glass. Since the upper end of the vertical glass 3 is completely fixed to the casing 5 via the upper fixing frame 4 and the lower end of the vertical glass 3 is completely fixed to the casing 5 via the lower fixing frame 6, the casing 5 is In response to an interlayer displacement due to an earthquake or the like, a force in the D direction acts on the upper fixed frame 4 side of the housing 5, a force in the E direction acts on the lower fixed frame 6 side, the housing tilts in the CC direction, and the displacement amount X The upper end and the lower end of the vertical glass 3 produce the same interlayer displacement amount X as that of the casing 5.

  On the other hand, the surface glass 2 receives the restraint of the sealing material (not shown) between the adjacent glass plates 1,... And the inertial force due to the weight of the glass plate 1 itself. In comparison, the interlayer displacement Y of the surface glass 2 generally tends to be small. That is, as an original phenomenon, the face glass 2 and the vertical glass 3 try to move differently during an earthquake.

  However, since the face glass 2 and the vertical glass 3 are bonded together by a high modulus sealing material cast over the entire joint 7, the vertical glass 3 and the vertical glass 3 are counteracted against the above-described action of different movement. The surface glass 2 and the vertical glass 3 try to perform the same movement in the portions other than the upper end portion and the lower end portion of the glass 3 (near the center), but as described above, the upper end portion and the lower portion of the vertical glass 3 are the casings. 5, the difference in displacement amount between the surface glass 2 and the vertical glass 3 increases in the vicinity of the upper end portion and the lower end portion.

  Therefore, the vertical glass 3 causes a substantially S-shaped displacement as shown by a broken line in FIG. 7, and the upper vicinity G and the lower vicinity F slightly from the center with respect to the upper end and the lower end of the vertical glass 3. Thus, a large bending load is applied to the vertical glass 3, and the vertical glass 3 may be damaged depending on the scale of the earthquake.

  In patent document 1, in order to solve the said problem, while suspending a surface glass from an upper housing, it is vertical glass via the double frame structure which slidably isolate | separates the lower end part of a vertical glass, and a lower housing. Is supported by the lower housing.

  According to Patent Document 1, due to the sliding action of the double frame structure, the vertical glass moves in the same manner as the face glass during an earthquake. Thereby, since a big bending displacement and bending stress are not added to the upper part vicinity of a vertical glass, and a lower part vicinity, a seismic performance is exhibited.

  However, since the glass screen structure of Patent Document 1 requires the double frame structure having a complicated structure, there is a problem that the entire glass screen structure has a complicated structure and the construction period is long.

  On the other hand, in the glass screen method disclosed in Patent Document 2, a sealant placed on the joint is used, a sealant with a high modulus is used in the vicinity of the center, and a medium modulus or a low modulus is used in the upper and lower parts excluding the vicinity of the center. By using this seal material, it has a mechanism to absorb the difference in movement during an earthquake.

  Since the structure of the glass screen structure of Patent Document 2 is simpler than the glass screen structure of Patent Document 1 provided with the double frame structure, there is an advantage that the construction period can be shortened. In addition, the said center vicinity part means the part containing the center part and the upper and lower vicinity part of a center part.

  The modulus of the sealing material is 50% modulus tensile stress (150%, which is 50% longer than the original length) when tested by the tensile adhesion test described in JIS A5758: 2010. (It means the tensile stress when it becomes length.) High modulus, medium modulus, and low modulus tensile stresses are described in US Pat.

  As the material for the high modulus and medium modulus sealant, silicone sealants such as deacetic acid type, deoxime type, and dealcohol type can be used. As the material for the low modulus sealing material, a silicone-based sealing material such as a deamidation type or a deamination type can be used.

JP-A-56-3784 Japanese Patent Laid-Open No. 9-67883

  However, since the glass screen structure of Patent Document 1 includes the double frame structure as described above, there is a problem that the structure becomes complicated.

  Moreover, in the glass screen construction method of patent document 2, since it is necessary to place two types of different sealing materials separately along the joint portion, it takes time and the construction period of the glass screen structure becomes long. there were.

  This invention is made | formed in view of such a situation, and it aims at providing the glass screen structure and glass screen construction method with an earthquake resistance which can be constructed in a short construction period with a simple structure.

  In order to achieve the above object, the present invention provides a flat glass in which a plurality of glass plates are arranged flush or at a predetermined angle, and a vertical direction of the glass plate adjacent to the flat glass. A glass that is disposed along a joint portion that is positioned and is bonded in a predetermined angular direction to the glass plate by a single sealing material that is placed along the joint portion. Provided is a screen structure, wherein an upper portion and a lower portion excluding the vicinity of the center portion in the height direction of the joint portion are subjected to adhesion prevention treatment by adhesion prevention treatment means. To do.

  In order to achieve the above object, the present invention comprises a plurality of glass plates that are flush with each other or arranged at a predetermined angle to form a surface glass, and the glass plates adjacent to the surface glass By arranging the vertical glass along the joint portion positioned in the vertical direction and placing a single sealing material along the joint portion, the vertical glass is placed in a predetermined angular direction with respect to the glass plate. It is a glass screen method formed by bonding, and after performing anti-adhesion treatment by an anti-adhesion treatment means on the upper and lower parts excluding the vicinity of the center in the height direction of the joint part, the sealing material is applied to the joint part. There is provided a glass screen method characterized in that it is cast over the entire length to bond the face glass and the vertical glass.

  According to the glass screen structure of the present invention, the seal material placed in the vicinity of the center of the joint portion has sufficient tensile strength, shear strength, Has adhesive strength. In addition, when an interlayer displacement occurs in the frame due to an earthquake or the like, even if the difference in displacement between the face glass and the vertical glass is large at the upper and lower parts of the vertical glass, the upper and lower parts of the vertical glass are Since the portion is not adhered to the surface glass by the adhesion prevention treatment by the adhesion prevention treatment means (hereinafter referred to as a non-adhesion portion), the upper and lower portions of the vertical glass move independently without being constrained by the surface glass. That is, the non-bonded portion absorbs the difference in movement between the face glass and the vertical glass when the interlayer displacement occurs. Therefore, since a large bending displacement and bending stress are not generated in the upper and lower portions of the vertical glass when the interlayer is displaced, it is possible to prevent the upper and lower portions of the vertical glass from being damaged when the interlayer displacement is generated. Therefore, the glass screen structure of the present invention has excellent seismic performance.

  The lower end part of the surface glass and the vertical glass of the present invention is fitted into a lower fixing frame fixed to the housing. For example, when supporting the load of surface glass and vertical glass at the lower end, the lower end of the surface glass and vertical glass is fitted into the lower fixed frame, and the surface glass is placed on the setting block installed in the lower fixed frame. And the lower end part of a vertical glass is mounted. Moreover, the upper end part of a surface glass and a standing glass is engage | inserted by the upper fixed frame fixed to the housing.

  On the other hand, when the glass screen structure is a suspended structure, the lower ends of the face glass and the vertical glass are fitted into the lower fixing frame, and the upper ends of the surface glass and the vertical glass are placed via the hanging metal fittings. Attach to the chassis.

  That is, the glass screen structure of the present invention is intended for the one in which at least the lower ends of the face glass and the vertical glass are fixed to the casing through the lower fixing frame.

  Furthermore, in order to simplify the structure of the glass screen structure, the present invention does not use the double frame structure described in Patent Document 1, and in order to shorten the construction period of the glass screen structure, A single sealing material is used without using two types of sealing materials described in Patent Document 2. As the sealing material, it is preferable to use a high modulus sealing material in order to set the adhesive strength of the adhesive portion to be equal to or greater than the design allowable stress value.

  The adhesion preventing treatment means of the present invention is preferably a tape that is affixed to the vertical glass or the face glass and is non-adhesive to the sealing material.

  In the glass screen structure of the present invention, a non-adhesive tape is attached to the vertical glass or the face glass with respect to the sealing material, so that an anti-adhesion treatment is applied to the upper and lower portions of the joint in the height direction. Can be applied.

  In the glass screen construction method of the present invention, a non-adhesive tape is attached in advance to the vertical glass or the face glass located at the upper and lower parts of the joint in the height direction. Then, the said sealing material is cast over the full length of the said joint part, and the said surface glass and the said standing glass are adhere | attached. As a result, the adhesive force of the non-adhesive portion becomes zero or less than the design allowable stress value.

  According to the present invention, a single sealing material may be cast along the joint, so that the construction period of the glass screen structure can be shortened as compared with the construction method of Patent Document 2.

  The adhesion preventing treatment means of the present invention is preferably a coating agent that is applied to the vertical glass or the face glass and is non-adhering to the sealing material.

  The glass screen structure of the present invention is obtained by applying a non-adhesive coating agent to the sealing material on the vertical glass or the face glass located at the upper and lower portions of the joint in the height direction. The adhesion preventing treatment can be applied to the upper part and the lower part in the height direction of the part.

  In the glass screen method of the present invention, a non-adhesive coating agent is applied in advance to the sealing glass or the face glass positioned at the upper and lower portions of the joint in the height direction. Then, the said sealing material is cast over the full length of the said joint part, and the said surface glass and the said standing glass are adhere | attached.

  As a result, the adhesive force of the non-adhesive portion becomes zero or less than the design allowable stress value.

  Moreover, since the present invention only has to place a single sealing material along the joint, the construction period of the glass screen structure can be shortened as compared with the construction method of Patent Document 2.

  In the glass screen structure and glass screen construction method of the present invention, the upper portion and the lower portion of the joint portion are less affected by wind resistance, and the length of the upper portion and the lower portion in the height direction is It is preferable that it is 1/2 of the length of the short side of a glass plate, or 1 meter.

  When the glass screen structure is subjected to wind pressure, the sealing material receives a linear load, but most of the wind pressure is borne by the vicinity of the center of the joint, and the burden on the upper and lower portions of the joint is small. Therefore, even if the upper part and the lower part of the joint part having little influence on wind resistance are used as non-bonded parts, a glass screen structure having no problem with wind resistance can be configured. In addition, the length of the up-down direction of a non-contact part is 1/2 of the length of the short side of the said glass plate, or 1 meter. Further, the lengths of 1/2 and 1 meter are not strict and include allowable values that can be assumed by those skilled in the art.

In the glass screen structure and the glass screen method of the present invention, the adhesive force of the seal material in the vicinity of the center of the joint is set to a design allowable stress value or more, and the design allowable stress value is 0.14 N / it is preferable that the mm ^2.

The design allowable stress value of 0.14 N / mm ^{2 according to the} present invention is determined by the glass frame construction method technical guideline (draft) (Publisher: Architectural Institute of Japan, January 25, 2011, first edition, first mark, P45). Based.

  The standing glass reinforces the face glass. A vertical glass may be arranged in two directions perpendicular to the surface glass (for example, the indoor side in the vertical direction and the outdoor side in the horizontal direction) at the joints (butting portions) of the adjacent glass plates of the surface glass. As described above, in order to improve the design, the vertical glass may be arranged only in one direction (vertical direction) perpendicular to the right angle. In the latter case, since a force such as wind is generally applied from the outdoor side toward the indoor side, the surface glass is supported by the force, and thus the vertical glass is disposed on the indoor side.

  According to the present invention, it is possible to provide a glass screen structure and a glass screen method that are earthquake resistant, have a simple structure, and can be constructed in a short construction period.

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

  FIG. 1 is an enlarged perspective view of a main part of a glass screen structure 10 according to an embodiment.

  The glass screen structure 10 is composed of a surface glass 14 in which a plurality of glass plates 12, 12... Are arranged flush with each other, and a plurality of vertical glasses 16. The vertical glass 16 is disposed along the joint portion 18 positioned in the vertical direction of the adjacent glass plates 12 and 12 of the face glass 14 and is placed along the joint portion 18 in FIG. The high modulus sealant 20 is bonded to the glass plate 12 in a direction perpendicular to the glass plate 12. FIG. 2 is a horizontal cross-sectional view taken along the line AA of the central vicinity 18A of the joint 18 shown in FIG. In addition, arrangement | positioning of the glass plates 12, 12 ... is not limited to the said surface, You may arrange | position with a predetermined angle. Further, the bonding direction of the vertical glass 16 is not limited to the perpendicular direction, and may be a predetermined angular direction.

  In the glass screen structure 10 according to the embodiment, as shown in FIG. 1, the center vicinity 18A in the height direction of the joint portion 18 is set as a bonding portion between the surface glass 14 and the vertical glass 16, and the center vicinity 18A is bonded. The force is set to the design allowable stress value or more. Further, the upper portion 18B and the lower portion 18C except for the central vicinity portion 18A in the height direction of the joint portion 18 are subjected to adhesion prevention processing by an adhesion prevention processing means described later. Thereby, the upper part 18B and the lower part 18C are set to the non-bonding part of the surface glass 14 and the vertical glass 16, and the adhesive force of the upper part 18B and the lower part 18C is set to be less than the design allowable stress value.

  The upper portion 18B and the lower portion 18C of the joint portion 18 are portions where the wind pressure resistance is less affected in the glass screen structure 10, and the length in the height direction of the upper portion 18B and the lower portion 18C is the length of the short side of the glass plate 12. It is preferable that it is 1/2 or 1 meter.

  In FIG. 3, the distribution in the height direction of the line load generated in the sealing material 20 when the glass screen structure 10 receives wind pressure is indicated by hatching.

  According to the figure, most of the wind pressure is borne by the central vicinity 18A of the joint 18 and the load of the upper part 18B and the lower part 18C is small. Therefore, even if the upper portion 18B and the lower portion 18C of the joint portion 18 having little influence on wind pressure resistance are used as non-bonded portions, the glass screen structure 10 having no problem with wind pressure resistance can be configured. Further, the length in the vertical direction of the upper portion 18B and the lower portion 18C is 1/2 or 1 meter of the short side of the glass plate 12 as described above, but the length of 1/2 or 1 meter is as described above. , Which are not exact and include tolerances that can be assumed by one skilled in the art.

Further, the design allowable stress value is preferably 0.14 N / mm ² . This value of 0.14 N / mm ² is based on the glass vertical construction technical guideline (draft) (issued by the Architectural Institute of Japan, January 25, 2011, first edition, first mark, P45).

  As shown in FIG. 1, the lower end portions of the face glass 14 and the vertical glass 16 are fitted into a lower fixing frame 24 </ b> A fixed to the housing 22. Thus, when supporting the load of the surface glass 14 and the vertical glass 16 by a lower end part, the lower end part of the surface glass 14 and the vertical glass 16 was fitted in the lower fixed frame 24A, and installed in the lower fixed frame 24A. The lower end portions of the face glass 14 and the vertical glass 16 are placed on a setting block (not shown). In the glass screen structure 10 of the embodiment, the upper end portions of the face glass 14 and the vertical glass 16 are fitted into an upper fixed frame 24B fixed to the housing 22 as shown in FIG. FIG. 4 is a schematic diagram.

  On the other hand, when the glass screen structure 10 is a suspended structure, the lower ends of the surface glass 14 and the vertical glass 16 are fitted into the lower fixing frame 24A, and the upper ends of the surface glass 14 and the vertical glass 16 are It is attached to the housing 22 via a hanging metal fitting (not shown). That is, the glass screen structure 10 according to the embodiment is intended for a structure in which at least the lower ends of the surface glass 14 and the vertical glass 16 are fixed to the housing 22 via the lower fixing frame 24A.

  FIG. 4 is an explanatory view schematically showing a state of displacement generated in the face glass 14 and the vertical glass 16 when the glass screen structure 10 of FIG. 1 is subjected to interlayer displacement due to an earthquake or the like.

  As described above, the upper end portion of the vertical glass 16 is completely fixed to the housing 22 through the upper fixing frame 24B, and the lower end portion of the vertical glass 16 is completely fixed to the housing 22 through the lower fixing frame 24A. When the housing 22 is subjected to interlayer displacement due to an earthquake or the like, a force in the D direction acts on the upper fixing frame 24B side of the housing 22, a force in the E direction acts on the lower fixing frame 24A side of the housing 22, and the housing 22 is C- When tilted in the C direction and displaced by the interlayer displacement X, the upper end portion and the lower end portion of the vertical glass 16 generate the same interlayer displacement amount X as that of the housing 22.

  On the other hand, the surface glass 14 receives the restraint by the sealing material 18 (see FIG. 2) between the adjacent glass plates 12 and 12 and the inertial force due to the weight of the glass plate 12 itself. Compared to X, the inter-layer displacement amount Y of the surface glass 14 generally tends to be reduced. That is, as a natural phenomenon, the surface glass 14 and the vertical glass 16 try to move differently during an earthquake.

  Up to this point, the glass screen structure of Patent Document 1 and the glass screen structure 10 of the embodiment have the same action. However, in Patent Document 1, the surface glass and the vertical glass have a high modulus seal in the entire joint area. Since it is bonded with a material, the surface glass and the vertical glass try to move in the same manner in portions other than the upper and lower portions of the joint. On the other hand, the upper end portion and the lower end portion of the vertical glass move in the same manner as the casing, and thus the difference in displacement between the face glass and the vertical glass becomes large at the upper end portion and the lower end portion. Therefore, as shown in FIG. 7, the vertical glass causes a substantially S-shaped displacement, and a large bending load is applied to the vertical glass at portions F and G (see FIG. 7) slightly from the center of the upper and lower ends of the vertical glass. In some cases, the glass plate was damaged depending on the scale of the earthquake.

  On the other hand, in the glass screen structure 10 according to the embodiment, the high modulus placed in the central vicinity portion 18A of the joint portion 18 against a force such as wind pressure acting in the out-of-plane direction of the surface glass 14. The sealing material 20 has sufficient tensile strength, shear strength, and adhesive strength.

  Further, when an interlayer displacement occurs in the housing 22 due to an earthquake or the like, even if the difference in displacement between the surface glass 14 and the vertical glass 16 is large at the upper and lower portions of the vertical glass 16, Since the upper part and the lower part are non-adhesive parts subjected to the adhesion prevention treatment, the upper part and the lower part of the vertical glass 16 move independently without being constrained by the surface glass 14. That is, the vertical glass 16 absorbs the difference in movement between the surface glass 14 and the vertical glass 16 when the non-bonded portion is generated between the layers, and moves along the CC direction in FIG. Therefore, since a large bending displacement and bending stress are not generated in the upper and lower portions of the vertical glass 16 when the interlayer is displaced, the upper and lower portions of the vertical glass can be prevented from being damaged when the interlayer displacement is generated. Therefore, the glass screen structure 10 of the embodiment has excellent earthquake resistance.

  Hereinafter, the form of the non-adhesion portion subjected to the adhesion prevention treatment by the adhesion prevention treatment means will be described with reference to FIGS. 5 and 6 are horizontal cross-sectional views of the upper portion 18B (the same applies to the lower portion 18C) of the joint portion 18 along the line BB in FIG.

  In the form of the adhesion preventing treatment means shown in FIG. 5, a non-adhesive tape 28 is attached to the sealing glass 20 on the vertical glass 16 or the face glass 14 of the upper portion 18 </ b> A (the same applies to the lower portion 18 </ b> C) of the joint portion 18. Thus, the upper portion 18A (the same applies to the lower portion 18C) of the joint portion 18 is subjected to an adhesion prevention treatment.

  The construction method of the glass screen structure 10 having the tape 28 is preliminarily applied to the vertical glass 16 or the face glass 14 of the upper portion 18A (the same applies to the lower portion 18C) of the joint portion 18 with the tape 28 that is not bonded to the sealing material 20 in advance. After pasting, the sealing material 20 is driven over the entire length of the joint 18 to bond the face glass 14 and the vertical glass 16 together.

  Thereby, since the adhesive force of the upper part 18A (same for the lower part 18C) of the joint part 18 becomes zero, the upper part 18A (same for the lower part 18C) of the joint part 18 can be made a non-adhesive part.

  Moreover, since this form should just drive the single sealing material 20 along the joint part 18, compared with the construction method of patent document 2, the construction period of the glass screen structure 10 can be shortened. Furthermore, as the non-adhesive tape 28, a polytetrafluoroethylene-based tape can be exemplified. In FIG. 5, the tape 28 is attached to both the vertical glass 16 and the face glass 14, but the tape 28 may be attached to at least one side of the vertical glass 16 and the face glass 14.

  In the form of the adhesion preventing treatment means shown in FIG. 6, the non-adhesive coating agent 30 is applied to the sealing material 20 on the vertical glass 16 or the face glass 14 of the upper portion 18 </ b> A (also the lower portion 18 </ b> C) of the joint portion 18. As a result, the upper portion 18A (the same applies to the lower portion 18C) of the joint portion 18 is subjected to adhesion prevention treatment.

  The construction method of the glass screen structure 10 to which the coating agent 30 is applied is the non-adhesive coating with respect to the sealing material 20 on the vertical glass 16 or the face glass 14 of the upper portion 18A (the same applies to the lower portion 18C) of the joint portion 18. After the agent 30 is applied in advance, the sealing material 20 is placed over the entire length of the joint 18 to bond the surface glass 14 and the vertical glass 16.

  Thereby, since the adhesive force of the upper part 18A (same for the lower part 18C) of the joint part 18 becomes zero, the upper part 18A (same for the lower part 18C) of the joint part 18 can be made a non-adhesive part.

  Moreover, since this form should just drive the single sealing material 20 along the joint part 18, compared with the construction method of patent document 2, the construction period of the glass screen structure 10 can be shortened. Further, examples of the non-adhesive coating agent 30 include polytetrafluoroethylene-based coating agents. In FIG. 6, the coating agent 30 is applied to both the face glass 14 and the vertical glass 16, but the coating agent 30 may be applied to either one of them.

  Moreover, in order to simplify the structure, the glass screen structure 10 of the embodiment does not use the double frame structure described in Patent Document 1, and shortens the work period of the glass screen structure 10. Therefore, the single sealing material 20 is used without using the two types of sealing materials described in Patent Document 2. As the sealing material 20, it is preferable to use a high modulus sealing material in order to set the adhesive force of the bonded portion to be equal to or greater than the design allowable stress value.
