Description

Technical Field

[0001] The utility model relates to a building connection structure, in particular to a building structural component connection structure with earthquake-resistant function. Background Art

[0002] During the construction process, building structural components are often connected to each other by bolting, so that the two building structural components can remain relatively fixed after being bolted together, avoiding loosening or displacement of the building structural components caused by external forces. However, the defect of the bolt connection structure is that when the building structural components are impacted by an earthquake, the building structural components will form a shear force on their connecting bolts during the vibration process, and the bolts need to overcome the shear force through their own stiffness to maintain the fixing effect. This makes it easy for the bolts to deform and break once the shear force exceeds the threshold, thereby greatly reducing the connection stability of the building structural components. Secondly, since the bolts will be hidden inside the building structural components after installation and cannot be directly observed, and before the bolts are completely broken, maintenance personnel cannot quickly detect whether they are intact, resulting in the maintenance personnel being unable to quickly check and eliminate the hidden dangers even if the bolts are damaged and there are safety hazards.

[0003] In view of the above problems, there is currently a solution to achieve the installation of the bolt connection structure by replacing the round hole with a long hole, that is, the friction resistance of the bolt after being fully tightened is used to limit the building structure components, so that the adjacent building structure components remain in a relatively fixed state under the action of friction resistance; once the force on the building structure components in the vibration direction reaches the threshold, the building structure components can overcome the friction resistance to form relative movement, thereby preventing the bolt from being cut off due to excessive force. However, the defect of this structure is that, on the one hand, there is an upper limit to the friction resistance applied by the bolt to the building structure component after tightening. Once the required connection strength of the building structure component is greater than the maximum resistance that the bolt can apply, it cannot be fixed in this way; on the other hand, the value of the friction resistance is also difficult to adjust based on design requirements, that is, the designer cannot accurately adjust the friction resistance applied by the bolt to the building structure component according to the required connection strength of the building structure component, which leads to a decrease in the stability of the building structure component after connection due to too small friction resistance; or due to excessive friction resistance, the bolt still has the risk of breaking, and the controllability is poor. In addition, when the bolts become loose due to stress, maintenance personnel cannot directly judge with the naked eye and can only eliminate the hidden danger by tightening each bolt in turn, which greatly increases the difficulty of maintenance and inspection of building facilities after an earthquake.

[0004] Therefore, the existing bolt connection method of building structural components has the problems of poor safety and inability to adjust the connection strength. Utility Model Content

[0005] The purpose of the utility model is to provide a building structural component connection structure with earthquake resistance, which can adjust the connection strength of the building structural component and release the rigid limit of the building structural component when the stress of the building structural component reaches a threshold, thereby preventing the bolt from breaking due to stress.

[0006] The technical solution of the utility model is as follows: a building structural member connection structure with earthquake-resistant function, comprising a first mounting portion, a first connecting portion and an earthquake-resistant connecting piece are respectively provided on the first mounting portion, the earthquake-resistant connecting piece and the first mounting portion are detachably connected, a deformation portion and a second connecting portion are respectively provided on the earthquake-resistant connecting piece, and the outer sides of the first mounting portion and the earthquake-resistant connecting piece are detachably connected with the second mounting portion via the first connecting portion and the second connecting portion;

[0007] The second mounting portion is used to fix and connect the first building structure member;

[0008] The first mounting portion is used for fixedly connecting to a second building structure member;

[0009] The first connecting portion is used to apply resistance to the second mounting portion in a vibration direction. When the force applied to the second mounting portion in the vibration direction exceeds a first threshold, the second mounting portion overcomes the resistance applied by the first connecting portion and forms a relative movement with the first mounting portion;

[0010] The anti-vibration connecting member is used to detachably connect the second mounting part via the second connecting part and apply resistance to the second mounting part in the vibration direction through the deformation part. When the force applied to the second mounting part in the vibration direction does not exceed the first threshold value, the deformation part maintains its own state unchanged and cooperates with the first connecting part to limit the second mounting part. When the force applied to the second mounting part in the vibration direction exceeds the first threshold value, the deformation part is deformed by the force and maintains a continuous connection between the second connecting part and the second mounting part.

[0011] In the aforementioned building structural component connection structure with earthquake-resistant function, when the movement distance of the second mounting part relative to the first mounting part in the vibration direction reaches a second threshold, the deformation part reaches the maximum deformation state after being deformed by force and forms a hard limit for the second mounting part, preventing the second mounting part from detaching from the first mounting part in the vibration direction.

[0012] In the aforementioned building structural component connection structure with earthquake resistance function, the first connection part includes a circular connection hole and an elongated hole respectively arranged on the first mounting part and the second mounting part, and the circular connection hole and the elongated hole are detachably connected via a first bolt connection structure.

[0013] In the aforementioned building structural member connection structure with earthquake resistance function, the deformation force to which the deformation portion is subjected when deforming under force is smaller than the shear force to which the first bolt connection structure is subjected when being cut off under force.

[0014] In the aforementioned building structural component connection structure with seismic resistance function, the deformation part is a metal folding plate arranged on the seismic resistance connecting member, and when the second mounting part moves along the vibration direction toward the side close to the seismic resistance connecting member, the metal folding plate deforms inward and contracts; when the second mounting part moves along the vibration direction toward the side away from the seismic resistance connecting member, the metal folding plate deforms outward and opens; when the movement distance of the second mounting part reaches a second threshold value, the metal folding plate is in a fully contracted or fully opened state and forms a hard limit for the second mounting part.

[0015] In the aforementioned building structural component connection structure with earthquake-resistant function, the first connection part is located in the middle of the first installation part, the number of the earthquake-resistant connecting parts is two and they are symmetrically arranged on both sides of the first connection part, a deformation part is formed in the middle of the earthquake-resistant connecting part, one end of the earthquake-resistant connecting part is detachably connected to the first installation part, and the other end of the earthquake-resistant connecting part is connected to the second connection part.

[0016] In the aforementioned building structural component connection structure with earthquake-resistant function, the earthquake-resistant connecting piece includes two connecting plates, which are connected to the first mounting part after overlapping each other, and the middle part of the connecting plate forms a V-shaped bend, and the V-shaped bends of the two connecting plates form a deformation part after being enclosed.

[0017] In the aforementioned building structural component connection structure with earthquake-resistant function, the second connection part is a second bolt connection structure.

[0018] Compared with the prior art, the utility model has the following characteristics:

[0019] (1) The utility model can use the deformation part to apply resistance along the vibration direction to the second mounting part through the structural cooperation between the first mounting part and the seismic connector. Then, when the force applied by the building structure component to the deformation part after vibration is less than the deformation force of the deformation part, the deformation part can maintain its own state unchanged and limit the second mounting part; when the force applied by the building structure component to the deformation part is greater than the deformation force of the deformation part, the deformation part will be deformed by force and release the limit on the second mounting part, so that the second mounting part can move relative to the first mounting part along the vibration direction, thereby achieving the connection effect of the second mounting part; and under the above cooperation, the designer only needs to control the deformation force of the deformation part to be less than the shear force required for the first bolt connection structure to be cut off, so that the utility model can release the limit on the second mounting part before the first bolt connection structure is cut off, thereby ensuring the stability of the first bolt connection structure; on this basis, the designer can also adjust the connection strength required for the second mounting part during installation by controlling the deformation force of the deformation part, thereby improving the limiting effect of the utility model on the building structure component;

[0020] (2) Since the building structure components are in a left-right reciprocating motion during an earthquake, the deformable portion can continue to deform and dissipate energy with the reciprocating motion during the vibration process, thereby having a buffering effect on the second installation portion, so that the vibration amplitude of the second installation portion under the buffering effect is smaller than that of the first installation portion, that is, reducing the damage of the building structure components under vibration;

[0021] (3) By limiting the structure of the deformation part, the movement distance of the second mounting part can also be adjusted. That is, when the second mounting part reaches the second threshold of the movement distance, the deformation part will be in a completely deformed state and form a hard limit for the second mounting part, thereby further improving the connection stability of the second mounting part and preventing the second mounting part from being separated after being vibrated.

[0022] (4) When maintenance personnel check the building structure components after an earthquake, they can also judge whether the second installation part has relative movement by the appearance of the deformed part. If the deformed part has deformation and contraction or deformation and expansion, it means that the second installation part has overcome the limit of the first bolt connection structure and has moved, and the operating personnel need to reset the building structure components, replace the seismic connectors and tighten the bolts; if the deformed part remains unchanged in its original size after the earthquake, it means that the building structure components have not shifted and the first bolt connection structure has no hidden dangers of deformation and fracture, which is convenient for maintenance personnel to check later;

[0023] (5) On the basis of the above, the present invention further defines the shape and connection structure of the seismic connector, which can achieve the fixing effect of the second mounting portion on the one hand, and can control the deformation force and deformation amplitude by adjusting the shape and thickness of the connecting piece or the metal folding plate, thereby achieving accurate adjustment of the connection strength and movement distance of the building structure member;

[0024] Therefore, the utility model can adjust the connection strength of the building structure components and release the rigid limit of the building structure components when the stress of the building structure components reaches a threshold, thereby preventing the bolts from breaking due to stress.

DETAILED DESCRIPTION

[0030] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0031] Embodiment 1. A building structural member connection structure with earthquake resistance, comprising: Figure 1-2 As shown, it comprises a first mounting portion 1, on which a first connecting portion 2 and an anti-seismic connecting member 3 are respectively provided, the anti-seismic connecting member 3 and the first mounting portion 1 are detachably connected, a deformation portion 4 and a second connecting portion 5 are respectively provided on the anti-seismic connecting member 3, and the outer sides of the first mounting portion 1 and the anti-seismic connecting member 3 are detachably connected with a second mounting portion 6 via the first connecting portion 2 and the second connecting portion 5;

[0032] The second mounting portion 6 is used to fix and connect the first building structure component;

[0033] The first mounting portion 1 is used for fixedly connecting a second building structure member;

[0034] The first connecting portion 2 is used to apply resistance to the second mounting portion 6 in a vibration direction. When the force applied to the second mounting portion 6 in the vibration direction exceeds a first threshold, the second mounting portion 6 overcomes the resistance applied by the first connecting portion 2 and forms a relative movement with the first mounting portion 1.

[0035] The seismic-resistant connecting member 3 is used to detachably connect the second mounting portion 6 via the second connecting portion 5 and to apply resistance to the second mounting portion 6 in the vibration direction through the deformation portion 4. When the force applied to the second mounting portion 6 in the vibration direction does not exceed the first threshold value, the deformation portion 4 maintains its own state unchanged and cooperates with the first connecting portion 2 to limit the second mounting portion 6. When the force applied to the second mounting portion 6 in the vibration direction exceeds the first threshold value, the deformation portion 4 is deformed by the force and maintains a continuous connection between the second connecting portion 5 and the second mounting portion 6.

[0036] When the moving distance of the second mounting part 6 relative to the first mounting part 1 in the vibration direction reaches a second threshold, the deformation part 4 reaches the maximum deformation state after being deformed by force and forms a hard limit for the second mounting part 6 to prevent the second mounting part 6 from detaching from the first mounting part 1 in the vibration direction.

[0037] The first connecting portion 2 includes a circular connecting hole and a long hole respectively arranged on the first mounting portion 1 and the second mounting portion 6. The circular connecting hole can be set as a threaded hole. The circular connecting hole and the long hole are detachably connected via a first bolt connecting structure 7. The length direction of the long hole is the vibration direction of the building structure component. After the second mounting portion 6 and the first mounting portion 1 are connected to each other via the first connecting portion 2, a hard limit is formed in the non-vibration direction.

[0038] The deformation resistance of the deformation portion 4 is smaller than the shear resistance of the first bolt connection structure 7 , that is, the deformation force on the deformation portion 4 when deformed by force is smaller than the shear force on the first bolt connection structure 7 when sheared by force.

[0039] The first connecting part 2 is located in the middle of the first mounting part 1, the number of the seismic connecting parts 3 is two and they are symmetrically arranged on both sides of the first connecting part 2, a deformation part 4 is formed in the middle of the seismic connecting part 3, one end of the seismic connecting part 3 is detachably connected to the first mounting part 1, and the other end of the seismic connecting part 3 is connected to the second connecting part 5.

[0040] The seismic connector 3 includes two long strips of connecting pieces 301, which are overlapped and fixed by bolts to the first mounting portion 1, and a V-shaped bend 302 is formed in the middle of the connecting piece 301. The V-shaped bends 302 of the two connecting pieces 301 are enclosed to form a deformation portion 4.

[0041] When the V-shaped bend 302 on one side of the building structural member is fully straightened, the deformation portion 4 is in a fully opened state and forms a hard limit on the second mounting portion 6. When the V-shaped bend 302 on one side of the second mounting portion 6 is fully compressed to form a T-shaped structure of the connecting piece 301, the deformation portion 4 is in a fully contracted state and forms a hard limit on the second mounting portion 6, thereby controlling the movement range of the second mounting portion 6.

[0042] The second connection portion 5 is a second bolt connection structure, and the anti-seismic connection member 3 and the second mounting portion 6 are provided with round holes or threaded holes that match the second bolt connection structure.

[0043] Working principle of the utility model: When the utility model is in use, the second mounting portion 6 and the outside of the first mounting portion 1 are respectively fixedly connected to two building structure members, and one side of the second mounting portion 6 is connected to the first mounting portion 1 via the first connecting portion 2, and the other side of the second mounting portion 6 is connected to the seismic connecting piece 3 via the second connecting portion 5, so that the second mounting portion 6 is limited by the cooperation of the seismic connecting piece 3 and the first mounting portion 1, so that the building structure member is in a fixed position unchanged during normal use.

[0044] When the building structure member is vibrated by external influence, the seismic connector 3 can keep the second mounting part 6 in position, and the deformation part 4 replaces the first bolt connection structure 7 to bear the impact force from the first mounting part 1. When the impact force received by the deformation part 4 is less than the deformation force of the deformation part 4, the deformation part 4 keeps its own structure unchanged and stably limits the second mounting part 6; when the impact force received by the deformation part 4 is greater than the deformation force of the deformation part 4, the deformation part 4 will be forced to shrink or open, and the position limit on the second mounting part 6 will be released, so that the second mounting part 6 can move on the first mounting part 1 along the vibration direction under the action of the first connection part 2, avoiding the first bolt connection structure 7 from being directly subjected to the shear force from the first mounting part 1 and causing breakage.

[0045] When the deformation amplitude of the deformation portion 4 reaches a threshold value, the deformation portion 4 will again form a hard limit on the second mounting portion 6, so that the second mounting portion 6 can only move back and forth within a preset moving range under the limit, thereby improving the limiting effect on the building structure component.

[0046] On the basis of the above-mentioned connection structure, the designer can adjust the thickness of the connection piece 301, the shape of the V-shaped bend 302 and other parameters as needed, so as to meet the designer's design requirements for the connection strength and movement range of the building structure components and improve the use effect of the utility model.

[0047] When maintenance personnel repair and troubleshoot building structural components after an earthquake, they can determine whether the building structural components have displacement problems by simply observing the deformation of the deformation portion 4. When the building structural components are displaced, maintenance personnel only need to replace the earthquake-resistant connector 3 and then tighten the first bolt connection structure 7 to complete the maintenance, which reduces the maintenance difficulty of maintenance personnel and improves their safety.

[0048] Embodiment 2. A building structural component connection structure with earthquake resistance, comprising: Figure 3 As shown, it comprises a first mounting portion 1, the exterior of the first mounting portion 1 is fixed to the building structural member via an embedded part, a first connecting portion 2 and a seismic connecting member 3 are respectively provided on the first mounting portion 1, the seismic connecting member 3 and the first mounting portion 1 are detachably connected, a deformation portion 4 and a second connecting portion 5 are respectively provided on the seismic connecting member 3, and a second mounting portion 6 is detachably connected to the exterior of the first mounting portion 1 and the seismic connecting member 3 via the first connecting portion 2 and the second connecting portion 5;

[0049] The second mounting portion 6 is used to fix and connect the first building structure component;

[0050] The first mounting portion 1 is used for fixedly connecting a second building structure member;

[0051] The first connecting portion 2 is used to apply resistance to the second mounting portion 6 in a vibration direction. When the force applied to the second mounting portion 6 in the vibration direction exceeds a first threshold, the second mounting portion 6 overcomes the resistance applied by the first connecting portion 2 and forms a relative movement with the first mounting portion 1.

[0052] The seismic-resistant connecting member 3 is used to detachably connect the second mounting portion 6 via the second connecting portion 5 and to apply resistance to the second mounting portion 6 in the vibration direction through the deformation portion 4. When the force applied to the second mounting portion 6 in the vibration direction does not exceed the first threshold value, the deformation portion 4 maintains its own state unchanged and cooperates with the first connecting portion 2 to limit the second mounting portion 6. When the force applied to the second mounting portion 6 in the vibration direction exceeds the first threshold value, the deformation portion 4 is deformed by the force and maintains a continuous connection between the second connecting portion 5 and the second mounting portion 6.

[0053] When the movement distance of the building structure component relative to the first mounting part 1 in the vibration direction reaches a second threshold, the deformation part 4 reaches the maximum deformation state after being deformed by force and forms a hard limit for the second mounting part 6 to prevent the second mounting part 6 from detaching from the first mounting part 1 in the vibration direction.

[0054] The first connecting portion 2 includes a circular connecting hole and a long hole respectively arranged on the first mounting portion 1 and the second mounting portion 6. The circular connecting hole can be set as a threaded hole. The circular connecting hole and the long hole are detachably connected via a first bolt connecting structure 7. The length direction of the long hole is the vibration direction of the building structure component. After the second mounting portion 6 and the first mounting portion 1 are connected to each other via the first connecting portion 2, a hard limit is formed in the non-vibration direction.

[0055] The deformation resistance of the deformation portion 4 is smaller than the shear resistance of the bolt, that is, the deformation force on the deformation portion 4 when deformed by force is smaller than the shear force on the bolt when sheared by force.

[0056] The deformation part 4 is a metal folding plate arranged in the middle of the seismic connector 3. The outer shape of the metal folding plate is Z-shaped. When the second mounting part 6 moves along the vibration direction toward the side close to the seismic connector 3, the metal folding plate deforms inward and contracts; when the second mounting part 6 moves along the vibration direction toward the side away from the seismic connector 3, the metal folding plate deforms outward and opens; when the moving distance of the second mounting part 6 reaches a second threshold value, the metal folding plate is in a fully contracted or fully opened state and forms a hard limit for the second mounting part 6.

[0057] The second connection portion 5 is a second bolt connection structure, and the anti-seismic connection member 3 and the second mounting portion 6 are provided with round holes or threaded holes that match the second bolt connection structure.

[0058] Compared with Example 1, this embodiment adjusts the shape and installation method of the seismic connector 3, and can also achieve the fixation and seismic effect of the second mounting part 6. Designers can also adjust the shape of the deformation part 4 as needed to meet the corresponding design requirements.

[0059] Embodiment 3. A building connection structure with earthquake resistance, comprising: Figure 4 As shown, it includes two split building structural components, which are a prefabricated external wall panel 100 and a structural frame 200. The prefabricated external wall panel 100 and the structural frame 200 are interconnected via the connecting structure in Example 1; when the connecting structure is in use, the second mounting portion 6 is fixedly connected to the four sides of the prefabricated external wall panel 100, and the outside of the first mounting portion 1 is fixedly connected to the structural frame 200 via embedded parts.

[0060] This embodiment uses the connection structure in Embodiment 1 to connect the prefabricated external wall panel 100 and the structural frame 200, so as to limit the position of the prefabricated external wall panel 100 on the structural frame 200. When the structural frame 200 vibrates due to an earthquake, the structural frame 200 drives the prefabricated external wall panel 100 to vibrate through the first mounting portion 1 and the seismic connector 3, and the prefabricated external wall panel 100 and the structural frame 200 are in a relatively fixed state.

[0061] When the driving force applied by the structural frame 200 to the second mounting portion 6 during vibration exceeds the deformation force of the deformation portion 4 (i.e., the driving force exceeds the first threshold), the deformation portion 4 will be deformed accordingly and the limit on the second mounting portion 6 will be released, so that the prefabricated external wall panel 100 and the structural frame 200 form a relative movement, that is, a shock absorption effect is achieved. When the relative movement distance between the second mounting portion 6 and the structural frame 200 reaches the second threshold, the deformation portion 4 is in a completely deformed state and forms a hard limit on the second mounting portion 6, thereby preventing the prefabricated external wall panel 100 from excessively deflecting or even detaching from the structural frame 200.
