Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated buildings, and particularly to a connection structure for seismic design of prefabricated building walls. Background Art

[0002] Prefabricated buildings have been widely used due to their advantages such as high efficiency and environmental protection. The connection structure of prefabricated building walls is a key part to ensure the overall stability and safety of the building. At present, most of the connection structures of prefabricated building walls adopt rigid connection methods. This kind of connection may be able to maintain the relative position stability of the walls during daily use, but in the face of natural disasters such as earthquakes, the ground will shake violently, and the building structure will then bear a strong seismic force. Due to the lack of sufficient deformation ability and buffer space in rigid connection, the walls are difficult to adjust their postures flexibly in response to the seismic shaking. When affected by seismic shaking, the forces on each part of the wall change sharply and are unevenly distributed. The rigid connection cannot effectively disperse and relieve this stress concentration, resulting in the pressure borne by the wall itself far exceeding its designed load-bearing limit, causing the wall to be extremely prone to cracks. As the cracks increase and expand, the integrity and load-bearing capacity of the wall are greatly reduced, which not only easily leads to the complete destruction of the building structure, but also poses a great threat to the lives of the people inside the building, and at the same time brings huge property losses. Summary of the Invention

[0003] The present invention provides a connection structure for seismic design of prefabricated building walls to solve the problem of low seismic performance of the existing connection of prefabricated building walls.

[0004] The following technical solutions are adopted for a connection structure for seismic design of prefabricated building walls of the present invention: A connection structure for seismic design of prefabricated building walls includes a first connecting member, a second connecting member, a locking member and a driving member.

[0005] The wall includes a plurality of wall panels. One edge of the wall panel is provided with a first installation groove, and the other edge of the wall panel is provided with a second installation groove. The first installation groove and the second installation groove are arranged in parallel. The first connecting piece includes a first arc-shaped plate which can be deformed.

[0008] Further, the driving piece includes a first driving plate and a second driving plate. The first driving plate is horizontally and fixedly arranged in the first installation groove, and the second driving plate is horizontally and fixedly arranged in the second installation groove. In the vertical direction, the first driving plate is located below the second installation plate, and the second driving plate is arranged above the first installation plate. When the two wall panels approach each other, the first driving plate squeezes the second arc-shaped plate, and the second driving plate squeezes the first arc-shaped plate.

[0009] Furthermore, the locking member includes a locking block which is arranged in an ellipsoidal shape. A first locking groove penetrating through the upper and lower side walls is provided in the middle of the first arc-shaped plate, and a second locking groove penetrating through the upper and lower side walls is provided in the middle of the second arc-shaped plate. The locking block is arranged in the first locking groove. When the first arc-shaped plate is in the second state and the second arc-shaped plate is in the third state, the locking block is simultaneously in the first locking groove and the second locking groove.

[0010] Furthermore, the locking member further includes a positioning groove and a positioning protrusion. There are two positioning grooves which are coaxially arranged on the locking block. The locking block has a major axis and a minor axis. The connection line of the two positioning grooves passes through the plane where the major axis is located, and the positioning grooves are arranged near one end of the locking block; there are two positioning protrusions which are coaxially and fixedly arranged in the first locking groove. Each positioning protrusion can enter one of the positioning grooves; when the first arc-shaped plate is in the first state, the major axis is in a horizontal state, and the first locking groove restricts the locking block from rotating around the positioning protrusion.

[0011] Furthermore, the locking member further includes a driving torsion spring and a mounting shaft. A driving groove is provided inside the locking block. The driving groove is coaxially and communicatively arranged with the positioning groove.

[0012] Furthermore, a plugging groove is provided at the end of the mounting shaft, and a plugging block is provided at the end of the positioning protrusion. When the positioning protrusion enters the positioning groove, the plugging block can enter the plugging groove.

[0014] Furthermore, a separating block is provided on the wall panel. When the two wall panels are in mutual abutment, the separating blocks on the two wall panels are spaced apart by a first preset distance.

[0015] The beneficial effects of the present invention are as follows: A connection structure for seismic design of prefabricated building walls according to the present invention includes a first connecting member, a second connecting member, a locking member, and a driving member. In a prefabricated building, the wall is formed by splicing multiple wall panels. By providing a first installation groove and a second installation groove at the longitudinal edges of the wall panels, when two wall panels are spliced, the first installation groove of one wall panel and the second installation groove of the adjacent wall panel are in a communicating state. The first arc-shaped plate in the first connecting member is arranged in the first installation groove, and the second arc-shaped plate in the second connecting member is arranged in the second installation groove. Both the first arc-shaped plate and the second arc-shaped plate can deform. Initially, the first arc-shaped plate is set in a first state of bulging upward, and the second arc-shaped plate is set in a fourth state of bulging downward. During the process of the two wall panels approaching each other, the driving member drives the first arc-shaped plate to change from the first state to the second state. At the same time, the driving member drives the second arc-shaped plate to change from the fourth state to the third state. When the first arc-shaped plate changes to the second state and the second arc-shaped plate changes to the third state, the locking member locks the first arc-shaped plate and the second arc-shaped plate. During an earthquake, the earthquake will cause the wall to shake, and adjacent two wall panels tend to move away from each other. At this time, the deformable first arc-shaped plate and second arc-shaped plate deform, thereby consuming the force exerted by the earthquake on the wall panels, and further reducing the probability of separation between adjacent two wall panels.

[0022] Such as Figures 1 to 7As shown in the figure, a connection structure for seismic design of prefabricated building walls provided by an embodiment of the present invention includes a first connector, a second connector, a locking member, and a driving member.

[0023] In a prefabricated building, there are a floor 110, a ceiling 120, and walls. The floor 110 is horizontally arranged on the ground. Multiple support rods 130 can be connected to the floor 110. The support rods 130 are vertically arranged. The ceiling 120 is fixedly connected to the support rods 130. The floor 110, the support rods 130, and the ceiling 120 form the framework of the prefabricated building. The walls are arranged between the floor 110 and the ceiling 120. Among them, the walls include multiple wall panels 140. A first installation groove 160 is arranged on one longitudinal edge of the wall panel 140, and a second installation groove 170 is arranged on the other longitudinal edge of the wall panel 140. On the same wall panel 140, the openings of the first installation groove 160 and the second installation groove 170 are arranged away from each other, and the first installation groove 160 and the second installation groove 170 are in a parallel state. Further, a sliding groove is arranged on the floor 110. The lower end of the wall panel 140 can be placed in the sliding groove, and the wall panel 140 can slide along the sliding groove, so as to facilitate arranging the wall panel 140 between the floor 110 and the ceiling 120.

[0024] The first connector includes a first arc-shaped plate 210. The first arc-shaped plate 210 can deform and has elasticity. The first arc-shaped plate 210 has a first state with an upward bulge and a second state with a downward bulge. The first arc-shaped plate 210 is arranged in the first installation groove 160. When the wall panel 140 is in a vertical state, the first arc-shaped plate 210 has a horizontal first critical state. In the initial state, adjacent two wall panels 140 are not in a state of being close to and abutting against each other, and the first arc-shaped plate 210 is in the first state. When a downward extrusion force is applied to the first arc-shaped plate 210, the first arc-shaped plate 210 first deforms to the first critical state. As the first arc-shaped plate 210 is further extruded, the first arc-shaped plate 210 can actively and quickly deform to the second state.

[0025] The second connecting member includes a second arc-shaped plate 220. The second arc-shaped plate 220 can be deformed and has elasticity. The second arc-shaped plate 220 has a third state with an upward bulge and a fourth state with a downward bulge. The second arc-shaped plate 220 is arranged in the second installation groove 170. When the wall panel 140 is in a vertical state, the second arc-shaped plate 220 is below the first arc-shaped plate 210. And the second arc-shaped plate 220 has a horizontal second critical state. In the initial state, two adjacent wall panels 140 are not in a state of being close to and abutting against each other. The second arc-shaped plate 220 is in the fourth state, and the bulging direction of the second arc-shaped plate 220 is opposite to that of the first arc-shaped plate 210. When an upward extrusion force is applied to the second arc-shaped plate 220, the second arc-shaped plate 220 first deforms to the second critical state. As the second arc-shaped plate 220 is further extruded, the second arc-shaped plate 220 can actively and quickly deform to the third state.

[0026] The driving member can drive the first arc-shaped plate 210 to change from the first state to the second state when the two wall panels 140 approach each other. The driving member can also drive the second arc-shaped plate 220 to change from the fourth state to the third state when the two wall panels 140 approach each other. Further, when the two wall panels 140 abut against each other, the first installation groove 160 and the second installation groove 170 communicate with each other. The driving member drives the first arc-shaped plate 210 and the second arc-shaped plate 220 simultaneously, so that the middle parts of the first arc-shaped plate 210 and the second arc-shaped plate 220 are in a close state. The locking member is used to lock the first arc-shaped plate 210 and the second arc-shaped plate 220 when the first arc-shaped plate 210 is in the second state and the second arc-shaped plate 220 is in the third state. When the middle parts of the first arc-shaped plate 210 and the second arc-shaped plate 220 are in a close state, the locking member is used to lock the first arc-shaped plate 210 and the second arc-shaped plate 220. Since the first arc-shaped plate 210 is arranged in the first installation groove 160 and the second arc-shaped plate 220 is arranged in the second installation groove 170, the first arc-shaped plate 210 and the second arc-shaped plate 220 are locked by the locking member, thereby fixing the splicing part of the two wall panels 140. Then, during an earthquake, the earthquake will cause the wall to shake, and two adjacent wall panels 140 tend to move away from each other. At this time, the deformable first arc-shaped plate 210 and second arc-shaped plate 220 deform, thereby consuming the force of the earthquake acting on the wall panel 140, and further reducing the probability of separation of two adjacent wall panels 140.

[0027] A connecting structure for seismic design of prefabricated building walls according to the present invention. In a prefabricated building, a wall is formed by splicing a plurality of wall panels 140. By providing a first installation groove 160 and a second installation groove 170 at the longitudinal edges of the wall panel 140, when two wall panels 140 are spliced, the first installation groove 160 of one wall panel 140 and the second installation groove 170 of the adjacent wall panel 140 are in a communicating state. The first arc-shaped plate 210 in the first connecting member is arranged in the first installation groove 160, and the second arc-shaped plate 220 in the second connecting member is arranged in the second installation groove 170. Both the first arc-shaped plate 210 and the second arc-shaped plate 220 can deform. Initially, the first arc-shaped plate 210 is set in a first state of bulging upward, and the second arc-shaped plate 220 is set in a fourth state of bulging downward. During the process of the two wall panels 140 approaching each other, the driving member drives the first arc-shaped plate 210 to change from the first state to the second state. At the same time, the driving member drives the second arc-shaped plate 220 to change from the fourth state to the third state. When the first arc-shaped plate 210 changes to the second state and the second arc-shaped plate 220 changes to the third state, the locking member locks the first arc-shaped plate 210 and the second arc-shaped plate 220. During an earthquake, the earthquake will cause the wall to shake, and adjacent two wall panels 140 tend to move away from each other. At this time, the deformable first arc-shaped plate 210 and second arc-shaped plate 220 deform, thereby consuming the force exerted by the earthquake on the wall panel 140, and further reducing the probability of separation between adjacent two wall panels 140.

[0028] In one embodiment, the first connecting member further includes a first mounting plate 230. The first mounting plate 230 is fixedly arranged in the first installation groove 160. When the wall panel 140 is in a vertical state, the first mounting plate 230 is in a horizontal state in the first installation groove 160. The first mounting plate 230 is provided with a first limiting groove penetrating up and down. The first arc-shaped plate 210 is arranged in the first limiting groove to ensure that the first arc-shaped plate 210 can deform smoothly on the first mounting plate 230. By providing the first mounting plate 230, an installation basis is provided for the first arc-shaped plate 210. Two first connecting rods 211 are fixedly connected to the first arc-shaped plate 210. The two first connecting rods 211 are arranged at intervals. The first connecting rods 211 do not interfere with the deformation of the first arc-shaped plate 210. The two first connecting rods 211 are at the same horizontal height. The first connecting rods 211 are rotatably connected to the side wall of the first limiting groove. By providing the first connecting rods 211, it is ensured that the connection between the first arc-shaped plate 210 and the first mounting plate 230 does not hinder the deformation of the first arc-shaped plate 210.

[0029] In one embodiment, the second connecting member further includes a second mounting plate 240 which is fixedly disposed in the second mounting groove 170. When the wall panel 140 is in a vertical state, the second mounting plate 240 is in a horizontal state within the second mounting groove 170. The second mounting plate 240 is provided with a second limiting groove penetrating up and down, and the second arc-shaped plate 220 is disposed in the second limiting groove to ensure that the second arc-shaped plate 220 can deform smoothly on the second mounting plate 240. By providing the second mounting plate 240, a mounting foundation is provided for the second arc-shaped plate 220. Two second connecting rods 221 are fixedly connected to the second arc-shaped plate 220. The two second connecting rods 221 are spaced apart. The second connecting rods 221 do not interfere with the deformation of the second arc-shaped plate 220. The two second connecting rods 221 are at the same horizontal height, and the second connecting rods 221 are rotatably connected to the side wall of the second limiting groove. By providing the second connecting rods 221, it is ensured that the connection between the second arc-shaped plate 220 and the second mounting plate 240 does not hinder the deformation of the first arc-shaped plate 210.

[0030] In one embodiment, the driving member includes a first driving plate 310 and a second driving plate 320. The first driving plate 310 is horizontally and fixedly disposed in the first mounting groove 160, and the second driving plate 320 is horizontally and fixedly disposed in the second mounting groove 170. When two adjacent wall panels 140 are both disposed in the sliding groove, in the vertical direction, the first driving plate 310 is below the second mounting plate 240, and the second driving plate 320 is above the first mounting plate 230. When the two wall panels 140 approach each other, the first driving plate 310 presses against the lower end surface of the second arc-shaped plate 220, causing the second arc-shaped plate 220 to change from the fourth state to the third state, and the second driving plate 320 presses against the upper end surface of the first arc-shaped plate 210, causing the first arc-shaped plate 210 to change from the first state to the second state. By providing the first driving plate 310 and the second driving plate 320, during the process of the two wall panels 140 approaching each other, it is ensured that the first arc-shaped plate 210 and the second arc-shaped plate 220 can smoothly change their states.

[0031] In one embodiment, the locking member includes a locking block 330, which is arranged in an ellipsoidal shape. A first locking groove 212 penetrating the upper and lower side walls is provided in the middle of the first arc-shaped plate 210, and a second locking groove 222 penetrating the upper and lower side walls is provided in the middle of the second arc-shaped plate 220. The locking block 330 is arranged in the first locking groove 212 and can rotate in the first locking groove 212. In the initial state, the first locking groove 212 hinders the rotation of the locking block 330. During the deformation process of the first arc-shaped plate 210 from the first state to the second state, the first locking groove 212 releases the hindrance to the rotation of the locking block 330. When the locking block 330 rotates, the locking block 330 can enter the second locking groove 222. Further, when the first arc-shaped plate 210 is in the second state and the second arc-shaped plate 220 is in the third state, the locking block 330 is simultaneously in the first locking groove 212 and the second locking groove 222, and then the locking block 330 completes the fixation of the first arc-shaped plate 210 and the second arc-shaped plate 220.

[0032] In one embodiment, the locking member further includes positioning grooves and a positioning protrusion 340. There are two positioning grooves, which are coaxially arranged on the locking block 330, and the opening directions of the two positioning grooves are opposite. Since the locking block 330 is ellipsoidal, the locking block 330 has a major axis and a minor axis. The connection line of the two positioning grooves passes through the plane where the major axis is located. In the initial state, the wall panel 140 is in a vertical state, the major axis of the locking block 330 is in a horizontal state, the minor axis of the locking block 330 is in a vertical state, and the connection line of the two positioning grooves passes through the plane where the major axis is located. The connection line of the two positioning grooves is not in the same plane as the vertical plane where the longitudinal axis is located, that is, the positioning grooves are arranged at the ends close to the major axis direction of the locking block 330. Further, there are two positioning protrusions 340, which are fixedly arranged on the side wall of the first locking groove 212, and the two positioning protrusions 340 are coaxially arranged. When the first arc-shaped plate 210 is in the first state, the staff can press the locking block 330 into the first locking groove 212, and each positioning protrusion 340 can enter one of the first locking grooves 212.

[0033] Further, when the first arc-shaped plate 210 is in the first state, the long axis is in the horizontal state, and the first locking groove 212 restricts the locking block 330 from rotating around the positioning protrusion 340. Specifically, when the first arc-shaped plate 210 is in the first critical state, the top view projection of the first locking groove 212 is elliptical, the long axis of the first locking groove 212 is equal to the long axis of the locking block 330, and the short axis of the first locking groove 212 is equal to the short axis of the locking block 330. In this state, the locking block 330 can rotate arbitrarily within the first locking groove 212. When the first arc-shaped plate 210 is in the first state, the first arc-shaped plate 210 deforms, and the first locking groove 212 also deforms. At this time, the first locking groove 212 hinders the rotation of the locking block 330, thereby ensuring that the locking block 330 remains stationary in the initial state.

[0034] In one embodiment, both the first arc-shaped plate 210 and the second arc-shaped plate 220 are provided as semi-ellipsoidal. When the first locking groove 212 is provided on the first arc-shaped plate 210, it is ensured that the thickness of the edge of the first locking groove 212 is the same, thereby ensuring that when the first arc-shaped plate 210 is in the first state, the side wall of the first locking groove 212 can uniformly squeeze the locking block 330, so that the locking block 330 maintains a stable state. Further, by making the second arc-shaped plate 220 have the same contour as the first arc-shaped plate 210, it is convenient for the locking block 330 to smoothly enter the second locking groove 222 after rotating in the first locking groove 212.

[0035] In one embodiment, the locking member further includes a driving torsion spring and a mounting shaft 350. A driving groove is provided inside the locking block 330. The driving groove is coaxially and communicatively provided with the positioning groove. The mounting shaft 350 is rotatably provided in the driving groove. The mounting shaft 350 and the first mounting plate 230 always remain relatively stationary. The driving torsion spring is provided between the outer side wall of the mounting shaft 350 and the inner side wall of the driving groove; in the initial state, the driving torsion spring is in a state of storing energy, and the restoring force of the driving torsion spring can drive the locking block 330 to rotate in the first locking groove 212. Since in the initial state, the first arc-shaped plate 210 is in the first state of bulging upward, the side wall of the first locking groove 212 hinders the rotation of the locking block 330, thereby enabling the driving torsion spring to stably remain in the state of storing energy initially.

[0036] In one embodiment, a plugging groove is provided at the end of the mounting shaft 350, and a plugging block is provided at the end of the positioning protrusion 340. When the positioning protrusion 340 enters the positioning groove, the plugging block can enter the plugging groove. By providing the plugging block and the plugging groove, during the deformation process of the first arc-shaped plate 210, the mounting shaft 350 and the first mounting plate 230 can remain relatively stationary.

[0037] In one embodiment, multiple groups of first connectors are provided, and the multiple groups of first connectors are evenly spaced along the length direction of the first installation groove 160; multiple groups of second connectors are provided, and the multiple groups of second connectors are evenly spaced along the length direction of the second installation groove 170. Each group of second connectors is correspondingly arranged with a group of first connectors. By providing multiple groups of first connectors and multiple groups of second connectors, the connection stability between two adjacent wall panels 140 is enhanced.

[0038] In one embodiment, two separation blocks 150 are provided on the wall panel 140, and the two separation blocks 150 are spaced apart. When the two wall panels 140 are in contact with each other, the separation blocks 150 on the two wall panels 140 are spaced apart by a first preset distance. The first preset distance is a parameter set manually. When it is necessary to separate the two wall panels 140, workers can insert tools such as crowbars into the gap between the two separation blocks 150, thereby improving the convenience of separating the two wall panels 140 and further reducing the probability of damage to the wall panels 140 when separating the two wall panels 140.
