Description
Technical Field
The invention relates to the technical field of buildings, in particular to an all-glass shear wall outer-wrapped friction type anti-seismic connecting node and an all-glass shear wall.
Background
In recent years, with the increasing manufacturing process and design technology, glass is becoming a structural material for directly bearing load, and is not limited to building envelope members and decorative members. Glass is applied to building structures, on one hand, the daylighting property of buildings is increased by fully utilizing the excellent light transmittance of materials, on the other hand, the aesthetic property is added to meet the visual effect of the buildings, and therefore the glass is widely concerned by architects, building owners and people in society. A series of innovations that use glass as a structural stress system are continuously provided, including glass beams, columns and floor slabs, glass stairs, gallery bridges and roofs, and full-glass structural systems, such as American apple company exclusive shops with extremely novel, attractive and architectural effects.
At present, the study of the earthquake resistant performance of the glass structure by scholars at home and abroad mainly focuses on the glass curtain wall, the glass panel of the curtain wall has higher interlayer deformation capability through reasonable node design, and the earthquake resistant performance of the whole structure is increased, and the study on the earthquake resistant performance of the directly bearing full glass structure node, member and system is urgently needed to be developed.
Glass is an ideal isotropic brittle material and generally cannot rely on the glass member itself to effectively dissipate seismic energy input to the structure. In the traditional all-glass structure earthquake-resistant design concept, the earthquake-resistant capacity of the structure is generally improved by increasing the rigidity and the strength of the structure, but the structure in the method can not be repaired due to serious damage after strong earthquake action, so that great economic loss and social influence are caused.
In recent years, the proposal of the concept of 'flexible city' puts forward new requirements on structural damage control, and a recoverable functional structural system becomes one of important research directions in the field of seismic engineering. The recoverable functional structure system mainly comprises a swing structure system, a self-resetting structure system, a structure system with replaceable components and the like. The swinging structural system with the replaceable components dissipates seismic energy by concentrating damage or deformation on the replaceable weak components, can isolate vibration by controlled swinging of the main structural components, and finally realizes a self-resetting function through gravity action or auxiliary measures, thereby ensuring that the main structural components have low damage or no damage characteristics.
Therefore, applying the concept of "toughness structure" to the design of all-glass structure and providing a large-shock and low-loss all-glass toughness structure system is a blank of research that needs to be solved by those skilled in the art.

Aiming at the problems that an all-glass structural system in the prior art is poor in anti-seismic performance and easy to damage, the invention aims to provide an outer-wrapped friction type anti-seismic connecting node of an all-glass shear wall and the all-glass shear wall.
In order to realize the purpose, the technical scheme of the invention is as follows:
in a first aspect, the invention provides an outer-wrapped friction type anti-seismic connecting node of a full-glass shear wall, which comprises a laminated glass shear wall, a first connecting piece and a second connecting piece; the laminated glass shear wall and the second connecting piece are respectively embedded in the laminated groove and the connecting groove, and the second connecting piece protrudes out of the connecting groove so as to be connected with the ground or a floor slab when in use; the laminated glass shear wall is connected with the first connecting piece in a laminated mode, the second connecting piece is detachably connected with the first connecting piece through a bolt, correspondingly, a bolt hole matched with the bolt is formed in the first connecting piece, a through hole for the bolt to penetrate through is formed in the second connecting piece, and the diameter of the through hole is larger than that of the bolt so that the first connecting piece and the second connecting piece can slide relatively under the shearing force exceeding a threshold value.
Preferably, the laminated glass shear wall comprises at least two glass panels which are arranged in a stacked mode, and a laminated glass intermediate film is arranged between every two adjacent glass panels.
Furthermore, a laminated glass intermediate film is arranged between the inner wall of the laminating groove and the surface of the laminated glass shear wall.
Preferably, the bolt is a high-strength friction type bolt.
The metal friction plate is arranged in the connecting groove, and a bolt hole matched with the bolt is formed in the metal friction plate; the metal friction plates are arranged on two sides of the second connecting piece to isolate the first connecting piece from the second connecting piece.
Preferably, the hardness of the metal friction plate is different from the hardness of the second connecting member.
In a second aspect, the invention further provides a friction type anti-seismic full-glass shear wall, which comprises the connecting node; the top end and the bottom end of the laminated glass shear wall are both connected with the first connecting pieces, and each first connecting piece is connected with the second connecting piece through a bolt.
The laminated glass shear wall comprises a laminated glass shear wall body and at least one laminated glass rib, wherein the laminated glass rib is connected to the same side face of the laminated glass shear wall body through silicone structural adhesive, and the laminated glass rib is arranged along the vertical height direction and is perpendicular to the laminated glass shear wall body; when one laminated glass rib is arranged, the laminated glass rib is arranged at the left end or the right end of the laminated glass shear wall, so that the cross section of the friction type anti-seismic full-glass shear wall is L-shaped; when the number of the laminated glass ribs is two, the two laminated glass ribs are symmetrically arranged at the left end and the right end of the same side face of the laminated glass shear wall, so that the cross section of the friction type anti-seismic full-glass shear wall is U-shaped.
In a third aspect, the invention further provides a friction type anti-seismic full-glass shear wall structure system, which comprises a plurality of friction type anti-seismic full-glass shear walls, wherein the side edges of the friction type anti-seismic full-glass shear walls are sequentially connected and enclose a circumferentially closed polygonal structure, and the side edges of two adjacent friction type anti-seismic full-glass shear walls are connected through silicone structural adhesive; and the inner surface of the friction type anti-seismic full-glass shear wall is connected with a laminated glass rib through silicone structural adhesive, and the laminated glass rib is perpendicular to the friction type anti-seismic full-glass shear wall.
Preferably, in a polygonal structure formed by surrounding the friction type anti-seismic full-glass shear walls, one side, far away from the corner, of the friction type anti-seismic full-glass shear wall at the corner is connected with the laminated glass rib, and two sides of the friction type anti-seismic full-glass shear wall at the non-corner are symmetrically connected with the laminated glass rib.
By adopting the technical scheme, the invention has the beneficial effects that:
1. because the laminated glass shear wall can be directly assembled into the first connecting piece without structural and shape adjustment due to the arrangement of the laminated grooves and the connecting grooves on the two ends of the first connecting piece in the connecting node, the diameters of the first connecting piece, the second connecting piece and the through holes in the first connecting piece which are connected through the bolts are larger than the diameters of the bolts, so that the connecting node for the laminated glass shear wall can provide good structural rigidity under the conditions of normal use and low vibration (the shearing force is smaller than a threshold value), the performance of the connecting node is equivalent to that of a fixed connection structure, and the first connecting piece and the second connecting piece can relatively slide under the shearing force exceeding the threshold value under the condition of high vibration (the shearing force exceeds the threshold value), so that the maximum internal stress required to be born by the laminated glass shear wall can be limited by controlling the friction force between the first connecting piece and the second connecting piece, and the damage degree (low loss or no damage) of the laminated glass shear wall can be accurately controlled;
in addition, in the repair after vibration, normal use functions of the full-glass shear wall can be quickly recovered only by screwing the bolts again and repairing the elastic joint formed by the silicone structural adhesive between the adjacent laminated glass shear walls in the full-glass shear wall, and the whole repair process is convenient and quick, economic and efficient.
2. Due to the arrangement of the metal friction plate and the arrangement that the hardness of the metal friction plate is different from that of the second connecting piece, the hysteresis energy consumption stability of the connecting node can be effectively improved, the abrasion of a friction interface can be effectively reduced, and the problem of mutual erosion of contact surface materials caused by long-time contact can be avoided;
3. due to the fact that the laminated glass ribs are connected to the surface of the full-glass shear wall through the silicone structural adhesive, after vibration occurs, the laminated glass ribs are damped through controlled swing, structural dynamic response is reduced, and the self-resetting function is achieved through the gravity effect after the vibration effect.

Example one
An outer-wrapped friction type anti-seismic connection node 100 of a full-glass shear wall is shown in figures 1-7 and comprises a laminated glass shear wall 1, a first connecting piece 3 and a second connecting piece 4.
The two opposite ends of the first connecting member 3 are respectively provided with a laminating groove and a connecting groove, namely in the embodiment, the first connecting member 3 comprises two connected parts, namely a laminating section 31 and a first connecting section 32, the laminating grooves are arranged along the length direction of the end surface of the laminating section 31, one end part of the laminated glass shear wall 1 is embedded in the laminating grooves in advance and is fixed by means of laminating connection, and as the laminated glass shear wall 1 usually has a larger transverse width dimension, in order to balance the internal stress in each position in the width direction, the embodiment is specifically configured that the length dimension of the first connecting member 3 (namely the length dimension of the laminating groove) is the same as the transverse width dimension of the laminated glass shear wall 1; the connecting grooves are respectively arranged at the left end and the right end of the first connecting section 32, so that the middle part of the first connecting section 32 is reserved with a space, and the reserved position is provided with a notch to reduce the weight and the material consumption of the first connecting piece 3. Correspondingly, the number of the second connecting pieces 4 is two, the two second connecting pieces 4 are respectively embedded in the two connecting grooves and detachably connected and fixed through bolts 6, and the second connecting pieces 4 protrude out of the connecting grooves so as to be connected to the ground or a floor slab when in use.
In this embodiment, the second connecting member 4 is configured to include two connected parts, namely a fixing section 41 and a second connecting section 42, the second connecting section 42 is configured to be embedded in the connecting groove of the first connecting member 3, and the fixing section 41 is configured to be connected to the ground or the floor slab when in use; wherein the fixing section 41 is perpendicular to the second connection section 42 so that the second connection member 4 can be firmly connected to the ground or the floor. Specifically, the first connecting section 32 of the first connecting member 3 is provided with a bolt hole 8 adapted to the bolt 6, the bolt hole 8 penetrates through the connecting groove, and the bolt hole 8 is a standard bolt hole, so as to prevent the bolt 6 from shaking therein; the second connecting section 42 of the second connecting member 4 is provided with a through hole 7 for the bolt 6 to pass through, and the diameter of the through hole 7 is larger than that of the bolt 6 so as to enable the first connecting member 3 and the second connecting member 4 to relatively slide under the shearing force exceeding the threshold value and keep stable connection under the shearing force not exceeding the threshold value.
In this embodiment, the laminated glass shear wall 1 includes at least two glass panels 101 stacked one on another, and a laminated glass intermediate film 5 is disposed between two adjacent glass panels 101. For the glass panels 101, each layer of the glass panels 101 may have different shapes and size parameters, and generally, the shape and size parameters are adjusted accordingly according to actual engineering requirements. In addition, each layer of the glass panel 101 may be made of the same type of glass or a combination of different types of glass, such as ultra-white tempered glass, semi-tempered glass, and basic annealed glass. The adhesion between the glass panel 101 and the laminated glass intermediate film 5 is good, so that there is no gap between the adjacent glass panels 101. The laminated glass intermediate film 5 also has the effects that when the laminated glass shear wall 1 is broken, glass fragments can be adhered to the laminated glass intermediate film 5, when the glass fragments arch or are locked in place, the glass fragments are mutually compacted to bear the pressure, the laminated glass intermediate film 5 bears the tension, the glass fragments and the intermediate film can work together to provide certain residual bearing capacity, and the size of the residual bearing capacity is directly related to the size of the glass fragments and the mechanical property of the laminated glass intermediate film 5, so that the laminated glass shear wall 1 has good mechanical property and safety, and can be used as load-bearing structural glass.
In this embodiment, the laminated glass interlayer 5 is configured as a polymer film, and in practical application, the laminated glass shear wall 1 can flexibly use polymer films with different mechanical properties according to application environments, and the polymer films include a polyvinyl butyral film (PVB film) and an ionic film (Sentry-Glas Plus abbreviated as SGP film) or other polymer films. The PVB film has relatively poor mechanical property and adhesive property and high temperature sensitivity, and the influence of the PVB film on the stress performance of the laminated glass shear wall 1 is limited. Relevant experimental research data at home and abroad show that the tear strength and durability of the SGP film are about 5 times of those of the traditional PVB film, the shear stiffness is about 50 times of those of the traditional PVB film (relevant to temperature and load action duration), and the hardness is about 30-100 times of those of the traditional PVB film. Therefore, the beneficial effect of the SGP film on the structural performance of the laminated glass shear wall 1 is not negligible, and the magnitude of the effect is closely related to the shear modulus and thickness of the laminated glass intermediate film (SGP). Meanwhile, compared with the traditional PVB laminated glass, the SGP laminated glass under the same conditions has excellent edge stability and weather resistance (can be directly exposed in air), does not generate chemical reaction when being in direct contact with a silicone structural adhesive, and has thinner structural thickness. Therefore, in view of the reliable mechanical properties of the SGP film and the good adhesion between the SGP film and the glass and the metal material, the SGP film is preferably selected as the laminated glass intermediate film 5 in the present embodiment.
It can be understood that the bolt 6 is used for tensioning the first connecting piece 3 and the second connecting piece 4, and generating static friction force between the first connecting piece 3 and the second connecting piece 4, and the first connecting piece 3 and the second connecting piece 4 are kept in a fastening connection relationship through the friction force, so the bolt 6 is preferably a high-strength friction type bolt in the embodiment; in addition, in order to improve the connection stability of the first connecting piece 3 and the second connecting piece 4, the first connecting piece 3 and the second connecting piece 4 are connected through a plurality of bolts 6.
Example two
The difference from the first embodiment is that: in this embodiment, in order to further avoid stress concentration, a laminated glass interlayer 5 is also provided between the inner wall where the lamination groove is provided and the surface of the laminated glass shear wall 1, as shown in fig. 1 and 3. And preferably, laminated glass intermediate films 5 are arranged on two opposite side surfaces and one bottom surface of the laminating groove, so that the laminated glass shear wall 1 embedded in the laminating groove is coated in all directions, and the laminated glass shear wall 1 is ensured not to be in direct contact with the laminating groove.
EXAMPLE III
The difference from the first embodiment is that: the connecting structure further comprises metal friction plates 13, the metal friction plates 13 are arranged in the connecting grooves, the number of the metal friction plates 13 is related to the number of the second connecting pieces 4, namely, the metal friction plates 13 are ensured to be uniformly distributed on two sides of the second connecting pieces 4 so as to isolate the first connecting pieces 4 from the second connecting pieces 3, and correspondingly, bolt holes 8 matched with the bolts 6 are formed in the metal friction plates 13. The arrangement is such that, when the shearing force exceeds a threshold value, the metal friction plate 13 moves together with the first connecting part 3, so that the friction between the first connecting part 3 and the second connecting part 4 is converted into friction between the second connecting part 4 and the metal friction plate 13.
And further, the hardness of the metal friction plate 13 is different from that of the second connecting piece 4, namely, the metal friction plate 13 is made of a metal material with a first hardness, and the second connecting piece 4 is made of a metal material with a second hardness, namely, the metal friction plate 13 and the second connecting piece 4 are made of two metal materials with different hardness. For example, the metal friction plate 13 is configured using a high hardness metal as a friction material, and the second joint member 4 uses a low hardness metal as a friction material.
By the arrangement, the hysteresis energy consumption stability of the friction node can be improved, and the problems of abrasion of a friction interface and mutual erosion of contact surface materials caused by long-time contact can be effectively reduced.
In addition, in terms of the selection of the metal material, the first connecting member 3 (the second connecting member 4 and the metal friction plate 13) made of the metal material is required to have the characteristic of being incompressible under the conditions of manufacture and stress, and of course, the metal material can also be a combination of multiple metal materials, such as titanium, aluminum, stainless steel and the like. In this embodiment, the first connecting member 3 is preferably made of a metal material having a similar thermal expansion coefficient to that of the glass panel 101, so that the internal stress of the laminated glass shear wall 1 caused by different thermal expansion coefficients during the manufacturing process such as heating or cooling can be reduced, and the cracking phenomenon of the laminated glass shear wall 1 due to the stress can be significantly reduced. And further preferably a titanium alloy having a thermal expansion coefficient close to that of annealed glass. Similarly, the selection conditions and requirements of the metal material also apply to the second connecting member 4 and the metal friction plate 13.
Example four
It will be understood that the configuration of the shape and the number of the first and second connectors 3, 4 may also vary, i.e. the connection node 100 has various forms under the inventive concept of the present invention, for example:
modification one: irrespective of the weight and material, the connecting grooves are arranged along the length of the first connecting section 32, so that the first connecting member 3 as a whole has a rectangular plate-like structure with an H-shaped cross section, as shown in fig. 8.
And (2) deformation II: under the condition of sufficient weight and material consumption, the laminated section 31 of the first connecting piece 3 in the first embodiment does not need to be the same as the transverse width of the laminated glass shear wall, a plurality of first connecting pieces 3 and a plurality of second connecting pieces 4 can be arranged and used in pairs, and the first connecting pieces 3 and the second connecting pieces 4 used in pairs are uniformly distributed at intervals along the width direction of the laminated glass shear wall 1, as shown in fig. 9, so that the purpose of reducing the weight and the material consumption of the connecting node 100 can be achieved under the condition that the internal stress applied to the laminated glass shear wall 1 is dispersed as much as possible so as to avoid stress concentration.
EXAMPLE five
A friction type earthquake-resistant full-glass shear wall 200, as shown in fig. 10, comprises the connection node disclosed in any one of the above embodiments; the top and bottom ends of the laminated glass shear wall 1 are connected with the first connecting pieces 3, and each first connecting piece 3 is connected with a second connecting piece 4 through a bolt 6.
It is understood that, in the fourth embodiment, when the connection node 100 has various deformation forms, the specific structural form of the friction type anti-seismic full-glass shear wall 200 provided in the present embodiment may also be changed accordingly, and the present embodiment is specifically described by taking the connection node 100 disclosed in the first embodiment as an example.
Example six
On the basis of the fifth embodiment: the present embodiment further provides an L-shaped friction type anti-seismic full-glass shear wall 300 and a U-shaped friction type anti-seismic full-glass shear wall 400, specifically, one and two sandwich glass ribs 9 are respectively added on the basis of the friction type anti-seismic full-glass shear wall 200.
The structure of the laminated glass rib 9 is similar to that of the laminated glass shear wall 1, and the difference is that the laminated glass rib 9 does not contain an embedded clamping groove 101; of course, the number of glass panels in the laminated glass rib 9 is irrelevant to the number of glass panels in the laminated glass shear wall 1, and the number of glass panels may be the same or different.
In the present embodiment, the laminated glass rib 9 is connected to the side of the laminated glass shear wall 1 by the silicone structural adhesive 10, and the laminated glass 9 is generally arranged in the vertical height direction and perpendicular to the laminated glass shear wall 1.
As shown in fig. 11, in the L-shaped friction type anti-seismic full-glass shear wall 300, one laminated glass rib 9 is installed at the left end or the right end of the laminated glass shear wall 1 in the friction type anti-seismic full-glass shear wall 200, so that the cross section of the friction type anti-seismic full-glass shear wall 200 changes and is L-shaped, thereby forming the L-shaped friction type anti-seismic full-glass shear wall 300.
As shown in fig. 12, in the U-shaped friction type anti-seismic full-glass shear wall 400, two laminated glass ribs 9 are symmetrically installed at the left end and the right end of the same side surface of the laminated glass shear wall 1 in the friction type anti-seismic full-glass shear wall 200, so that the cross section of the friction type anti-seismic full-glass shear wall 200 is changed and is U-shaped, thereby forming the U-shaped friction type anti-seismic full-glass shear wall 400.
Similarly, other numbers of laminated glass ribs 9 may be further installed on the surface of the friction type anti-seismic full-glass shear wall 200 disclosed in the fifth embodiment, so as to form other types of full-glass shear walls, and the description of this embodiment is omitted.
So set up, through installing laminated glass rib 9 through silicone structural adhesive 10 on friction formula antidetonation full glass shear force wall 200, when user state and vibration (for example earthquake) take place, because silicone structural adhesive 10 has elasticity, therefore laminated glass rib 9 can take place controlled the rocking for laminated glass shear force wall 1 to reduce the structural dynamic response of full glass shear force wall, make after the earthquake action, the major structure of full glass shear force wall can realize from the reset function through the action of gravity.

In this embodiment, the polygonal structure defined by the plurality of friction type anti-seismic full-glass shear walls 200 is preferably a rectangle, such as a square, each side includes 3 friction type anti-seismic full-glass shear walls 200, and the whole friction type anti-seismic full-glass shear wall structure system 500 includes 12 friction type anti-seismic full-glass shear walls 200. In another embodiment, the polygonal structure defined by the plurality of friction type earthquake-resistant full-glass shear walls 200 may also be other shapes, such as pentagons or hexagons, and the specific shape is determined according to the building requirements.
