Description

Technical Field

[0001] The utility model relates to a prefabricated external wall panel, in particular to an earthquake-resistant prefabricated wall panel. Background Art

[0002] External wall panels are an integrated prefabricated material used for building exterior walls, and are usually fixed to the structural frame of the building exterior wall by bolt connection. However, the defect of the conventional bolt connection structure is that the building wall will vibrate during an earthquake, and the driving force will be transmitted to the external wall panels through the bolts during the vibration, so that the external wall panels will vibrate synchronously with the structural frame after being stressed. Once the driving force applied by the building wall to the bolt exceeds the maximum bearing range of the bolt, it is easy to cause the force of the bolt to be cut off, which poses a major safety hazard.

[0003] In view of the above hidden dangers, 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 external wall panel, so that the external wall panel is fixed to the structural frame under the action of friction resistance; once the driving force applied to the bolt by the structural frame during vibration is greater than the friction resistance, slippage will occur between the bolt and the external wall panel, and the external wall panel and the structural frame will form a relative movement along the vibration direction, thereby achieving a shock absorption effect and preventing the bolt from being cut off due to excessive force. However, the defect of this connection method is that, on the one hand, there is an upper limit to the friction resistance applied by the bolt to the external wall panel after tightening. Once the connection strength required for the external wall panel is greater than the maximum resistance that the bolt can apply, it cannot be fixed by this method; 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 external wall panel according to the connection strength required for the external wall panel, which results in the external wall panel After the connection, the friction resistance is too small, resulting in a decrease in its limiting effect; or the friction resistance is too large, resulting in it being unable to form relative movement, and the controllability is poor.

[0004] In addition, when personnel were checking for hidden dangers on external wall panels after an earthquake, they were unable to determine with the naked eye whether the bolts were fully tightened and could only tighten each bolt one by one to eliminate the hidden dangers, which greatly increased the difficulty of maintenance and inspection of building facilities after an earthquake.

[0005] Therefore, the existing installation method for external wall panels has the problems of poor installation stability and difficulty in subsequent maintenance. Utility Model Content

[0006] The purpose of the utility model is to provide an earthquake-resistant prefabricated wall panel, which can improve the installation stability of the prefabricated wall panel and facilitate the later maintenance of the processing personnel.

[0007] The technical solution of the utility model is as follows: the earthquake-resistant prefabricated wall panel comprises a prefabricated wall panel, a plurality of second mounting parts for connecting to a structural frame are arranged around the prefabricated wall panel, and an earthquake-resistant component detachably connected to each second mounting part; the earthquake-resistant component comprises a first mounting part, a first connecting part and an earthquake-resistant connecting piece are respectively arranged on the first mounting part, the earthquake-resistant connecting piece and the first mounting part are detachably connected, a deformation part and a second connecting part are respectively arranged on the earthquake-resistant connecting piece, and two sides of the second mounting part are detachably connected to the first mounting part and the earthquake-resistant connecting piece via the first connecting part and the second connecting part;

[0008] The first mounting portion is used to fix the connection structure frame and limit the position of the second mounting portion;

[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 the deformation portion and forms a relative movement with the first mounting portion;

[0010] The seismic-resistant 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 2. When the force applied to the second mounting part 2 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 earthquake-resistant prefabricated wall panel, 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 on the second mounting part to prevent the second mounting part from detaching from the first mounting part in the vibration direction.

[0012] In the aforementioned earthquake-resistant prefabricated wall panel, the first connecting portion includes a circular connecting hole and an elongated hole respectively arranged on the first mounting portion and the second mounting portion, and the circular connecting hole and the elongated hole are detachably connected via a first bolt connecting structure.

[0013] In the aforementioned earthquake-resistant prefabricated wall panel, the deformation force to which the deformation portion is subjected when deforming under stress is smaller than the shear force to which the first bolt connection structure is subjected when being cut off under stress.

[0014] In the aforementioned seismic prefabricated wall panel, the deformation part includes a metal folding plate arranged on the seismic connecting member. When the second mounting part moves along the vibration direction toward the side close to the seismic 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 connecting member, the metal folding plate deforms outward and opens; when the moving 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 earthquake-resistant prefabricated wall panel, the outer shape of the metal folded plate is V-shaped, Z-shaped or diamond-shaped.

[0016] In the aforementioned earthquake-resistant prefabricated wall panel, the first connecting portion is located in the middle of the first mounting portion, and the number of the earthquake-resistant connecting members is two and they are symmetrically arranged on both sides of the first connecting portion.

[0017] In the aforementioned earthquake-resistant prefabricated wall panels, the earthquake-resistant connectors include multiple split connecting plates, the two ends of which are respectively connected to the second mounting portion and the first mounting portion, and a metal folding plate is provided in the middle of each connecting plate. The metal folding plates of the multiple connecting plates form a deformation portion after being enclosed or overlapped.

[0018] In the aforementioned earthquake-resistant prefabricated wall panel, the second connection portion is a second bolt connection structure.

[0019] Compared with the prior art, the utility model has the following characteristics:

[0020] (1) The utility model can use the deformation part to apply resistance to the second installation part along the vibration direction through the structural cooperation of the first installation part and the seismic connection piece. Then, when the force applied by the structural frame to the deformation part after the vibration is less than the deformation force of the deformation part, the deformation part can maintain its own state unchanged and limit the second installation part, so that the prefabricated wall panel and the structural frame are kept in a relatively fixed state; when the force applied by the structural frame 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 installation part, so that the second installation part can move relative to the first installation part along the vibration direction; 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 by force, so that the utility model can release the limit on the second installation 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 installation part during installation by controlling the deformation force of the deformation part, thereby improving the limiting effect of the utility model on the prefabricated wall panel;

[0021] (2) Since the structural frame will form a left-right reciprocating motion during an earthquake, the deformable portion can also be continuously deformed 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 prefabricated wall panel under the buffering effect is smaller than that of the structural frame, that is, reducing the damage of the prefabricated wall panel under vibration;

[0022] (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.

[0023] (4) When maintenance personnel conduct hidden danger inspection on prefabricated wall panels 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 problems of 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 operator needs to reset the prefabricated wall panel, replace the seismic connector and tighten the bolts; if the deformed part remains in its original size and is not damaged after the earthquake, it means that the prefabricated wall panel has not shifted and the first bolt connection structure has no hidden dangers of deformation and fracture, which is convenient for maintenance personnel to conduct later inspections;

[0024] (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 of the metal folded plate by adjusting the shape and thickness of the metal folded plate, thereby achieving accurate adjustment of the connection strength and movement distance of the prefabricated wall panel;

[0025] Therefore, the utility model can improve the installation stability of the prefabricated wall panels and facilitate the later maintenance of the processing personnel. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] 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.

[0033] Embodiment 1. Earthquake-resistant prefabricated wall panels, comprising Figure 1-3 As shown, it includes a prefabricated wall panel 1, and a plurality of second mounting parts 2 for connecting to a structural frame are arranged around the prefabricated wall panel 1, and also includes a seismic-resistant assembly detachably connected to each second mounting part 2; the seismic-resistant assembly includes a first mounting part 3, and a first connecting part 4 and a seismic-resistant connecting member 5 are respectively arranged on the first mounting part 3, and the seismic-resistant connecting member 5 and the first mounting part 3 are detachably connected, and a deformation part 6 and a second connecting part 7 are respectively arranged on the seismic-resistant connecting member 5, and the two sides of the second mounting part 2 are detachably connected to the first mounting part 3 and the seismic-resistant connecting member 5 via the first connecting part 4 and the second connecting part 7;

[0034] The first mounting portion 3 is used to fix the connection structure frame and limit the position of the second mounting portion 2;

[0035] The first connecting portion 4 is used to apply resistance to the second mounting portion 2 in a vibration direction. When the force applied to the second mounting portion 2 in the vibration direction exceeds a first threshold, the second mounting portion 2 overcomes the resistance applied by the first connecting portion 4 and the deformation portion 6 and forms a relative movement with the first mounting portion 3.

[0036] The seismic-resistant connecting member 5 is used to detachably connect the second mounting part 2 via the second connecting part 7 and apply resistance to the second mounting part 2 in the vibration direction through the deformation part 6. When the force applied to the second mounting part 2 in the vibration direction does not exceed the first threshold value, the deformation part 6 maintains its own state unchanged and cooperates with the first connecting part 4 to limit the second mounting part 2. When the force applied to the second mounting part 2 in the vibration direction exceeds the first threshold value, the deformation part 6 is deformed by the force and maintains a continuous connection between the second connecting part 7 and the second mounting part 2.

[0037] When the moving distance of the second mounting part 2 relative to the first mounting part 3 in the vibration direction reaches a second threshold, the deformation part 6 reaches the maximum deformation state after being deformed by force and forms a hard limit for the second mounting part 2 to prevent the second mounting part 2 from detaching from the first mounting part 3 in the vibration direction.

[0038] The first connecting part 4 includes a circular connecting hole and a long hole respectively arranged on the first mounting part 3 and the second mounting part 2. 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 8. The length direction of the long hole is the vibration direction of the prefabricated wall panel 1. After the second mounting part 2 and the first mounting part 3 are connected to each other via the first connecting part 4, a hard limit is formed in the non-vibration direction.

[0039] The deformation resistance of the deformation portion 6 is smaller than the shear resistance of the first bolt connection structure 8 , that is, the deformation force on the deformation portion 6 when deformed by force is smaller than the shear force on the first bolt connection structure 8 when sheared by force.

[0040] The deformation portion 6 includes a metal folding plate arranged on the seismic connector 5, and the outer shape of the metal folding plate is V-shaped. When the second mounting portion 2 moves along the vibration direction toward the side close to the seismic connector 5, the metal folding plate deforms inward and contracts; when the second mounting portion 2 moves along the vibration direction toward the side away from the seismic connector 5, the metal folding plate deforms outward and opens; when the moving distance of the second mounting portion 2 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 portion 2.

[0041] The first connection portion 4 is located in the middle of the first mounting portion 3 , and the number of the anti-seismic connection members 5 is two and they are symmetrically arranged on both sides of the first connection portion 4 .

[0042] The seismic connecting member 5 includes a plurality of split connecting plates 501, which overlap with each other and are fixed by bolts when connected, and the two ends of the connecting plate 501 are respectively connected to the second mounting part 2 and the first mounting part 3, and a metal folding plate is provided in the middle of each connecting plate 501. The metal folding plates of the plurality of connecting plates 501 form a deformation part 6 with a diamond structure after being enclosed or overlapped.

[0043] When the metal folding plate on one side of the second mounting part 2 is fully straightened, the deformation part 6 is in a fully opened state and forms a hard limit on the second mounting part 2. When the metal folding plate on one side of the second mounting part 2 is fully compressed to form a T-shaped structure of the connecting piece 501, the deformation part 6 is in a fully contracted state and forms a hard limit on the second mounting part 2, thereby controlling the movement range of the second mounting part 2.

[0044] The second connection portion 7 is a second bolt connection structure, and the anti-seismic connection member 5 and the second mounting portion 2 are provided with round holes or threaded holes that match the second bolt connection structure.

[0045] Working principle of the utility model: When the utility model is in use, the first mounting part 3 is first fixed to the structural frame through the embedded parts, and then the second mounting part 2 is limited by the cooperation of the first mounting part 3 and the seismic connecting part 5, so that the prefabricated wall panel 1 remains fixed with the structural frame under the limiting action.

[0046] When the structural frame is vibrated by external influences, the seismic connector 5 can keep the second mounting part 2 in position, and the deformation part 6 replaces the first bolt connection structure 8 to bear the impact force from the first mounting part 3. When the impact force received by the deformation part 6 is less than the deformation force of the deformation part 6, the deformation part 6 keeps its own structure unchanged and stably limits the second mounting part 2; when the impact force received by the deformation part 6 is greater than the deformation force of the deformation part 6, the deformation part 6 will be forced to shrink or open, and the position limit on the second mounting part 2 will be released, so that the second mounting part 2 can move on the first mounting part 3 in the vibration direction under the action of the first connection part 4, avoiding the first bolt connection structure 8 from being directly subjected to the shear force from the first mounting part 3 and causing breakage.

[0047] When the deformation amplitude of the deformation portion 6 reaches a threshold value, the deformation portion 6 will form a hard limit on the second mounting portion 2, so that the second mounting portion 2 can only move back and forth within a preset moving range under the limit, thereby improving the limiting effect on the prefabricated wall panel 1.

[0048] Based on the above-mentioned connection structure, designers can adjust parameters such as the thickness of the connecting piece 501 and the shape of the metal folding plate as needed, thereby meeting the designer's design requirements for the connection strength and movement range of the prefabricated wall panel 1 and improving the use effect of the utility model.

[0049] When maintenance personnel repair and troubleshoot the prefabricated wall panel 1 after an earthquake, they only need to observe the deformation of the deformation portion 6 to determine whether the prefabricated wall panel 1 has a displacement problem. When the prefabricated wall panel 1 is displaced, the maintenance personnel only need to replace the earthquake-resistant connector 5 and then tighten the first bolt connection structure 8 to complete the maintenance, which reduces the maintenance difficulty of the maintenance personnel and improves their safety.

[0050] Embodiment 2. Earthquake-resistant prefabricated wall panels, comprising Figure 4As shown, it includes a prefabricated wall panel 1, and a plurality of second mounting parts 2 for connecting to a structural frame are arranged around the prefabricated wall panel 1, and also includes a seismic-resistant assembly detachably connected to each second mounting part 2; the seismic-resistant assembly includes a first mounting part 3, and a first connecting part 4 and a seismic-resistant connecting member 5 are respectively arranged on the first mounting part 3, and the seismic-resistant connecting member 5 and the first mounting part 3 are detachably connected, and a deformation part 6 and a second connecting part 7 are respectively arranged on the seismic-resistant connecting member 5, and the two sides of the second mounting part 2 are detachably connected to the first mounting part 3 and the seismic-resistant connecting member 5 via the first connecting part 4 and the second connecting part 7;

[0051] The first mounting portion 3 is used to fix the connection structure frame and limit the position of the second mounting portion 2;

[0052] The first connecting portion 4 is used to apply resistance to the second mounting portion 2 in a vibration direction. When the force applied to the second mounting portion 2 in the vibration direction exceeds a first threshold, the second mounting portion 2 overcomes the resistance applied by the first connecting portion 4 and the deformation portion 6 and forms a relative movement with the first mounting portion 3.

[0053] The seismic-resistant connecting member 5 is used to detachably connect the second mounting part 2 via the second connecting part 7 and apply resistance to the second mounting part 2 in the vibration direction through the deformation part 6. When the force applied to the second mounting part 2 in the vibration direction does not exceed the first threshold value, the deformation part 6 maintains its own state unchanged and cooperates with the first connecting part 4 to limit the second mounting part 2. When the force applied to the second mounting part 2 in the vibration direction exceeds the first threshold value, the deformation part 6 is deformed by the force and maintains a continuous connection between the second connecting part 7 and the second mounting part 2.

[0054] When the moving distance of the second mounting part 2 relative to the first mounting part 3 in the vibration direction reaches a second threshold, the deformation part 6 reaches the maximum deformation state after being deformed by force and forms a hard limit for the second mounting part 2 to prevent the second mounting part 2 from detaching from the first mounting part 3 in the vibration direction.

[0055] The first connecting part 4 includes a circular connecting hole and a long hole respectively arranged on the first mounting part 3 and the second mounting part 2. 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 8. The length direction of the long hole is the vibration direction of the prefabricated wall panel 1. After the second mounting part 2 and the first mounting part 3 are connected to each other via the first connecting part 4, a hard limit is formed in the non-vibration direction.

[0056] The deformation resistance of the deformation portion 6 is smaller than the shear resistance of the first bolt connection structure 8 , that is, the deformation force on the deformation portion 6 when deformed by force is smaller than the shear force on the first bolt connection structure 8 when sheared by force.

[0057] The deformation portion 6 includes a metal folding plate arranged on the seismic connector 5, and the outer shape of the metal folding plate is Z-shaped. When the second mounting portion 2 moves along the vibration direction toward the side close to the seismic connector 5, the metal folding plate deforms inward and contracts; when the second mounting portion 2 moves along the vibration direction toward the side away from the seismic connector 5, the metal folding plate deforms outward and opens; when the moving distance of the second mounting portion 2 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 portion 2.

[0058] When the metal folding plate on one side of the second mounting part 2 is fully straightened, the deformation part 6 is in a fully opened state and forms a hard limit on the second mounting part 2. When the metal folding plate on one side of the second mounting part 2 is fully compressed to form a cross-shaped structure of the seismic connector 5, the deformation part 6 is in a fully contracted state and forms a hard limit on the second mounting part 2, thereby controlling the movement range of the second mounting part 2.

[0059] The second connection portion 7 is a second bolt connection structure, and the anti-seismic connection member 5 and the second mounting portion 2 are provided with round holes or threaded holes that match the second bolt connection structure.

[0060] Compared with Example 1, this embodiment adjusts the shape and installation method of the seismic connector 5, and can also achieve the limiting effect on the second installation part 2. Designers can also adjust the shape of the deformation part 6 as needed to meet corresponding design requirements.
