Description

Technical Field

[0001] This invention belongs to the field of vibration damping connection structure, and particularly relates to a prefabricated self-resetting vibration damping connection structure and construction method. Background Technology

[0002] In related technologies, building construction typically involves first pouring a reinforced concrete frame structure, and then building walls to divide the rooms. Generally, workers need to construct these walls internally using bricklaying, but this method is inefficient. Therefore, prefabricated walls have emerged. Prefabricated walls are usually prefabricated, one-piece structures that can be used directly after being transported to the construction site.

[0003] However, prefabricated walls in related technologies are usually monolithic structures. In high-rise buildings or earthquake-prone areas, the connecting structures between prefabricated walls are prone to deformation or even damage under vibration during assembly and use. Moreover, after vibration, the deformation of the connecting structures between prefabricated walls accumulates, making it difficult to reset. Over a long period of use, this can easily lead to the breakage of the connecting structures between prefabricated walls, resulting in wall collapse and endangering the lives of residents. Summary of the Invention

[0004] The technical objective of this invention is to provide a prefabricated self-resetting vibration damping connection structure and construction method, aiming to solve the problem that prefabricated walls are prone to vibration deformation or even damage in related technologies.

[0006] Furthermore, the first wall panel has a first groove on the side near the second wall panel, the guide hole is located in the first groove, and the two opposite side walls of the first groove have locking recesses; the positioning assembly also includes a fixing block embedded in the locking recesses and a second spring with its two ends respectively fixed to the outside of the docking rod and the fixing block.

[0007] Furthermore, the positioning assembly also includes a limiting frame slidably mounted outside the docking rod. The length of the limiting frame is greater than the length of the first groove, and the width of the limiting frame is greater than the width of the first groove. A limiting groove is provided on the side of the limiting frame facing the first wall panel, and the limiting groove is used to accommodate the fixing block and the second spring.

[0008] Furthermore, the positioning assembly also includes a detection rod with one end fixed to the docking rod and the other end extending into the shock-absorbing shell, and the end of the shock-absorbing shell is provided with a third groove; wherein, when the first wall panel and the second wall panel are installed in place, the end of the detection rod is located in the third groove.

[0009] Furthermore, both the end of the shock-absorbing shell and the end of the shock-absorbing rod are fixedly connected to a first connecting rod. The vibration damping assembly also includes a fixing frame provided on the adjacent sides of the first wall panel and the second wall panel. The shock-absorbing rod is rotatably assembled with the fixing frame of the first wall panel through the first connecting rod thereon, and the shock-absorbing shell is rotatably assembled with the fixing frame of the second wall panel through the first connecting rod thereon.

[0010] Furthermore, a fixing rod is provided on one side of the second wall panel, and one end of the pull rope is fixed to the fixing rod; a pulley is provided on the first connecting rod of the shock-absorbing rod, one end of the pull rope is fixed to the shock-absorbing rod, and the pull rope is wound around the pulley.

[0011] Furthermore, the fixing frame has a U-shaped structure, the first connecting rod is rotatably connected to the U-shaped notch of the fixing frame, and the bottom of the fixing frame is installed on the first wall panel or the second wall panel by a fixing nut.

[0012] Furthermore, both the first wall panel and the second wall panel are provided with plastic bags on the side opposite to the fixing frame, and the first connecting rod is provided with a needle tube; wherein, when the first wall panel and the second wall panel are installed in place, one end of the needle tube is inserted into the corresponding plastic bag, and the other end of the needle tube is aligned with the fixing nut at the corresponding position.

[0013] Furthermore, a construction method for a prefabricated self-resetting vibration damping connection structure is provided, comprising: adjusting the first wall panel and the second wall panel to a preset position; rotatably connecting one end of the vibration damping rod of the vibration damping component to the first wall panel; rotatably connecting one end of the vibration damping shell of the vibration damping component to the second wall panel; moving the second wall panel toward the first wall panel until the limiting frame abuts against the first wall panel; inserting the connecting rod into the guide hole; and transferring the fixing block of the positioning component to the first groove and engaging with the locking recess; and after pre-tightening the pull rope, fixing one end of the pull rope to the second wall panel.

The push plate is fixed to the end of the movable sleeve, and the bottom side of the push plate is close to the top side of the limiting area. Adjusting the first wall panel and the second wall panel to the preset position includes: placing the first wall panel and the second wall panel within the limiting area, with the outer side of the first wall panel close to the edge of the worktable and the outer side of the second wall panel close to the push plate. Moving the second wall panel toward the first wall panel includes: starting the motor, which drives the threaded rod to rotate, thereby moving the movable sleeve. The push plate follows the movable sleeve. When the push plate moves to the preset position, the motor is turned off.

[0015] Compared with existing technologies, the prefabricated self-resetting vibration damping connection structure and construction method of this invention have the following advantages:

[0016] As a prefabricated self-resetting damping connection structure, when vibration occurs, the first and second wall panels move closer or further apart. When the first and second wall panels move closer, the damping rod moves inward toward the damping shell. At this time, the outer side of the damping rod rubs against the inner side of the damping shell, and the damping material of the damping rod is compressed, converting mechanical energy into heat energy. The first spring is compressed, and the excess energy is converted into elastic potential energy by the first spring to provide the elastic force that moves the first and second wall panels away from each other. When the first and second wall panels move away from each other, the damping rod moves inward toward the damping shell. At this time, the outer side of the damping rod rubs against the inner side of the damping shell, converting mechanical energy into heat energy. If the distance between the first and second wall panels exceeds a preset distance, the pull rope will limit and block the damping rod, causing the damping rod to retract into the damping shell, thereby limiting the further opening of the damping assembly. Thus, under the combined action of the damping rod, damping shell, first spring, and pull rope, the first and second wall panels will vibrate back and forth, while the damping rod and damping shell will slide back and forth, thereby gradually converting mechanical energy into heat energy for dissipation and achieving vibration reduction. Moreover, due to the limiting effect of the pull rope and the elastic force of the first spring, when the energy is dissipated, the first and second wall panels will return to the preset position, achieving self-reset.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0028] Combination Figure 1-5In this embodiment, a prefabricated self-resetting vibration damping connection structure is provided, including a first wall panel 1, a second wall panel 2 spaced apart from the first wall panel 1, a positioning component disposed between the first wall panel 1 and the second wall panel 2, a vibration damping component 3 disposed between the first wall panel 1 and the second wall panel 2, and a pull rope 309 connecting the first wall panel 1 and the vibration damping component 3; the first wall panel 1 is provided with a guide hole on the side near the second wall panel 2, the positioning component includes a docking rod 201 fixed to the second wall panel 2 and slidably connected in the guide hole; the vibration damping component 3 includes a vibration damping rod 303 rotatably connected at one end to the first wall panel 1, a vibration damping shell 301 rotatably connected at one end to the second wall panel 2 and sleeved on the outside of the vibration damping rod 303, and a first spring 302 disposed in the vibration damping shell 301 and connected at one end to the vibration damping rod 303, wherein the outer material of the vibration damping rod 303 is a damping material, the vibration damping rod 303 and the vibration damping shell 301 are interference-fitted, and one end of the pull rope 309 is fixed to the vibration damping rod 303.

[0029] Before use, the prefabricated self-resetting vibration damping connection structure can be rotatably connected to the damping rod 303 and damping shell 301 of the vibration damping component 3, respectively. The docking rod 201 of the positioning component and the guide hole are aligned. Then, the first wall panel 1 and the second wall panel 2 are brought closer together, and the docking rod 201 is inserted into the guide hole. After the first wall panel 1 and the second wall panel 2 reach a predetermined distance, the pull rope 309 on the damping rod 303 is pre-tightened and fixed to one side of the first wall panel 1, thus forming a prefabricated wall. Afterwards, the first wall panel 1 and the second wall panel 2 are installed in their respective positions on the building, such as the bottom and top sides of the floor slab, completing the wall assembly quickly and easily.

[0030] When the wall vibrates, there are two actions: the first wall panel 1 and the second wall panel 2 move closer to each other or move further apart. When the first wall panel 1 and the second wall panel 2 approach each other, the damping rod 303 moves toward the inside of the damping shell 301. At this time, the outer side of the damping rod 303 rubs against the inner side of the damping shell 301, and the damping material of the damping rod 303 is compressed, converting mechanical energy into heat energy. The first spring 302 is compressed, and the excess energy is converted into elastic potential energy by the first spring 302 to provide elastic force to move the first wall panel 1 and the second wall panel 2 away from each other. When the first wall panel 1 and the second wall panel 2 move away from each other, the damping rod 303 moves toward the inside of the damping shell 301. At this time, the outer side of the damping rod 303 rubs against the inner side of the damping shell 301, converting mechanical energy into heat energy. If the distance between the first wall panel 1 and the second wall panel 2 exceeds the preset distance, the pull rope 309 will limit and block the damping rod 303, causing the damping rod 303 to retract into the damping shell 301, thereby limiting the vibration damping assembly 3 from continuing to open. Thus, under the combined action of the damping rod 303, the damping shell 301, the first spring 302, and the pull rope 309, the first wall panel 1 and the second wall panel 2 will reciprocate, and the damping rod 303 and the damping shell 301 will also reciprocate, thereby gradually converting mechanical energy into heat energy for dissipation and achieving vibration reduction. Moreover, due to the limiting effect of the pull rope 309 and the elastic force of the first spring 302, when the energy is dissipated, the first wall panel 1 and the second wall panel 2 will return to the preset position, achieving self-reset.

[0031] As can be seen, the prefabricated self-resetting damping connection structure of this embodiment can absorb and dissipate seismic energy using damping devices, and at the same time restore the structure to its initial position after an earthquake through a self-resetting mechanism, thereby reducing structural damage and improving safety. The prefabricated self-resetting damping connection structure is suitable for various building structure types, including residential, commercial buildings, and public facilities. Especially in earthquake-prone areas, this structure can significantly improve the seismic performance of the structure and protect people's lives and property.

[0032] Furthermore, the first wall panel 1 is provided with a first groove 102 on the side near the second wall panel 2, and the guide hole is located in the first groove 102. The two opposite side walls of the first groove 102 are provided with locking recesses. The positioning assembly also includes a fixing block 203 embedded in the locking recess and a second spring 202 whose two ends are respectively fixed to the outside of the connecting rod 201 and the fixing block 203. Specifically, in this embodiment, the first wall panel 1 has two first grooves 102 on the side near the second wall panel 2, located at both ends of the vibration damping component 3. Each of the two first grooves 102 has a guide hole and a locking recess. Correspondingly, the second wall panel 2 has two connecting rods 201 on one side. Each connecting rod 201 has a second spring 202 and a fixing block 203. During the pre-installation of the self-resetting vibration damping connection structure, it is only necessary to insert the two connecting rods 201 into the guide holes and engage the corresponding fixing blocks 203 in the locking recesses. This is convenient and quick. The cooperation of the fixing blocks 203 and the second springs 202 can stably position the connecting rods 201 in the first grooves 102. Because the connecting rods 201 and the guide holes are slidably connected, when the first wall panel 1 and the second wall panel 2 vibrate, they can achieve stable movement towards or away from each other. In some implementations, one, three, or four connecting rods 201 can be provided, and correspondingly, the number of first grooves 102 can also be provided.

[0033] Furthermore, the positioning assembly also includes a limiting frame 204 slidably mounted outside the docking rod 201. The length of the limiting frame 204 is greater than the length of the first groove 102, and the width of the limiting frame 204 is greater than the width of the first groove 102. A limiting groove is provided on the side of the limiting frame 204 facing the first wall panel 1, and the limiting groove is used to accommodate the fixing block 203 and the second spring 202. Specifically, the length direction of the limiting frame 204 is the same as the length direction of the corresponding first groove 102, the length of the limiting groove is less than the length of the first groove 102, the width of the limiting groove is less than the width of the first groove 102, and when the docking rod 201 and the guide hole are aligned, the projection of the limiting groove on the axis of the guide rod falls into the first groove 102. When the first wall panel 1 and the second wall panel 2 are not installed together, the second spring 202 and the fixing block 203 on the docking rod 201 are both accommodated in the limiting groove. Therefore, the length of the two fixing blocks 203 is less than the length of the first groove 102. When the fixing block 203 is in contact with the side wall of the limiting groove under the action of the second spring 202, during the docking process, when the docking rod 201 is inserted into the guide hole and continues to move a certain distance, the limiting frame 204 will abut against the first wall plate 1 and slide relative to the docking rod 201. The two fixing blocks 203 begin to slide away from the limiting groove. When the positions of the two fixing blocks 203 are completely away from the limiting groove, the fixing blocks 203 are located in the first groove 102, and under the elastic force of the second spring 202, the two fixing blocks 203 are respectively locked in the locking recess, thereby making the connection between the docking rod 201 and the guide hole stable. In order to make it easier for the fixing blocks 203 to enter the first groove 102, the part of the opening of the first groove 102 facing away from the locking recess is set as a guide slope.

[0034] It should be understood that the positioning component enables the first wall panel 1 and the second wall panel 2 to be positioned accurately and connected reliably, while the vibration damping component 3 realizes the connection between the first wall panel 1 and the second wall panel 2 as well as vibration damping. In this way, vibration damping and self-resetting can be achieved while ensuring installation reliability, resulting in higher reliability.

[0035] Furthermore, to make the wall more aesthetically pleasing, a second groove 101 is provided on the side of the first wall panel 1 near the second wall panel 2. The first groove 102 is located inside the second groove 101, and one end of the shock-absorbing rod 303 is fixed inside the second groove 101. Thus, when the first wall panel 1 and the second wall panel 2 are pre-installed, the vibration damping component 3 can be completely housed inside the second groove 101, making the wall more aesthetically pleasing. To ensure integrity, a portion of the second wall panel 2 can be inserted into the second groove 101 around the inner wall of the second groove 101. This can seal the second groove 101 and allow the first wall panel 1 and the second wall panel 2 to slide against each other during vibration, thereby further ensuring the reliability of the shock absorption and self-resetting functions.

[0036] Furthermore, the positioning assembly also includes a detection rod 205, one end of which is fixed to the docking rod 201 and the other end extends into the shock-absorbing housing 301. The end of the shock-absorbing housing 301 is provided with a third groove 311. When the first wall panel 1 and the second wall panel 2 are installed in place, the end of the detection rod 205 is located within the third groove 311. After the first wall panel 1 and the second wall panel 2 are docked, the end of the detection rod 205 and the third groove 311 are aligned, thereby identifying whether the first wall panel 1 and the second wall panel 2 are installed in place. In some implementations, a position sensor can be installed within the third groove 311. The position sensor is used to detect whether the end of the detection rod 205 is in place. The position sensor can be a capacitive sensor, a photoelectric sensor, or an ultrasonic sensor, etc.

[0037] Furthermore, both the end of the damping shell 301 and the end of the damping rod 303 are fixedly connected to a first connecting rod 304. The damping assembly 3 also includes a fixing frame 305 provided on the adjacent sides of the first wall panel 1 and the second wall panel 2. The damping rod 303 is rotatably assembled with the fixing frame 305 of the first wall panel 1 via the first connecting rod 304 thereon, and the damping shell 301 is rotatably assembled with the fixing frame 305 of the second wall panel 2 via the first connecting rod 304 thereon. Specifically, the fixing frame 305 has a U-shaped structure, the first connecting rod 304 is rotatably connected to the U-shaped notch of the fixing frame 305, and the bottom of the fixing frame 305 is installed on the first wall panel 1 or the second wall panel 2 via a fixing nut 307. In some embodiments, plastic bags 4 are provided on the opposite sides of the first wall panel 1 and the second wall panel 2 to the fixing frame 305, and a needle tube 310 is provided on the first connecting rod 304. When the first wall panel 1 and the second wall panel 2 are installed in place, one end of the needle tube 310 is inserted into the corresponding plastic bag 4, and the other end of the needle tube 310 is aligned with the corresponding fixing nut 307. During installation, when the first wall panel 1 and the second wall panel 2 are installed in place, the first connecting rod 304 rotates to its position, causing one end of the needle tube 310 to insert into the corresponding plastic bag 4. At this time, the glue in the plastic bag 4 flows through the needle tube 310 to the fixing nut 307, thereby providing auxiliary fixation for the fixing frame 305. Furthermore, the glue can cover the fixing nut 307, isolating it from air and moisture, preventing corrosion, and increasing its service life.

[0038] Furthermore, a fixing rod 206 is provided on one side of the second wall panel 2, and one end of the pull rope 309 is fixed to the fixing rod 206; a pulley 308 is provided on the first connecting rod 304 on the shock absorber 303, and one end of the pull rope 309 is fixed to the shock absorber 303, and the pull rope 309 is wound around the pulley 308. Specifically, the first connecting rod 304 on the shock absorber 303 has a gap in the middle, and a pulley 308 is disposed within this gap. The two ends of the pull rope 309 are respectively fixed to the first wall panel 1 and the shock absorber 303. The pull rope 309 passes through the gap in the middle of the first connecting rod 304 and is wound around the pulley 308. With this arrangement, the tension of the pull rope 309 is first transmitted to the shock absorber 303, then buffered by the pulley 308, and finally transmitted to the second wall panel 2 through the fixing frame 305. This is equivalent to multiple layers of buffering, making the impact between the first wall panel 1 and the second wall panel 2 more gentle and effectively preventing damage. The pull rope 309 can be elastic, thereby preventing rigid collisions and stretching, resulting in higher reliability. In some embodiments, one end of the pull rope 309 can be fixed to the shock absorber shell 301.

[0039] Furthermore, combined Figure 6-7 A construction method is provided for realizing the aforementioned prefabricated self-resetting vibration damping connection structure, comprising:

[0040] S1. Adjust the first wall panel 1 and the second wall panel 2 to the preset position, rotate one end of the damping rod 303 of the damping component 3 to the first wall panel 1, and rotate one end of the damping shell 301 of the damping component 3 to the second wall panel 2.

[0041] S2. Move the second wall panel 2 toward the first wall panel 1 until the limiting frame 204 abuts against the first wall panel 1, the connecting rod 201 is inserted into the guide hole, and the fixing block 203 of the positioning component is transferred to the first groove 102 and engaged with the locking groove.

[0042] S3. After pre-tightening the pull rope 309, fix one end of the pull rope 309 to the second wall panel 2.

[0043] The above construction method utilizes a work frame, which includes a worktable 501, a motor 502, a threaded rod 503, a movable sleeve 504, and a push plate 505. The top surface of the worktable 501 is recessed to form a limiting area. The motor 502 is fixed to the edge of the worktable 501. The threaded rod 503 is connected to the output end of the motor 502 and extends towards the limiting area. The movable sleeve 504 is threadedly connected to the threaded rod 503. The push plate 505 is fixed to the end of the movable sleeve 504, with its bottom side pressed against the top side of the limiting area. It should be understood that when the motor 502 starts, the push plate 505 can be moved through the cooperation of the threaded rod 503 and the movable sleeve 504.

[0044] The detailed steps are as follows:

[0045] The drive motor 502 moves the push plate 505 to the initial position, placing the first wall panel 1 and the second wall panel 2 within the limiting area. The outer side of the first wall panel 1 is close to the edge of the worktable 501, and the outer side of the second wall panel 2 is close to the push plate 505. At this time, the docking rod 201 is aligned with the guide hole. One end of the damping rod 303 of the vibration damping component 3 is rotatably connected to the first wall panel 1 through the fixing frame 305 and the first connecting rod 304. One end of the damping shell 301 of the vibration damping component 3 is rotatably connected to the second wall panel 2 through the fixing frame 305 and the first connecting rod 304, thus realizing the initial connection of the vibration damping component 3.

[0046] Start motor 502, which drives threaded rod 503 to rotate, thereby moving movable sleeve 504. Push plate 505 moves with movable sleeve 504. At this time, second wall plate 2 moves closer to first wall plate 1, shock absorber rod 303 is gradually compressed and retracted into shock absorber sleeve, docking rod 201 is inserted into guide hole and continues to move. Limiting frame 204 abuts against one side of first wall plate 1, and docking rod 201 continues to slide relative to limiting frame 204, thereby driving second spring 202 and fixing block 203 to move towards first groove 102. When fixing block 203 disengages from limiting groove of limiting frame 204, fixing block 203 is engaged with the locking groove under the action of second spring 202. When push plate 505 moves to preset position, end of detection rod 205 corresponds to third groove 311. At this time, first wall plate 1 and second wall plate 2 are installed in place, and motor 502 is turned off.

[0047] One end of the pull rope 309, which is fixed to the shock absorber 303 and passes over the pulley 308, is pre-tightened. Then, the other end of the pull rope 309 is fixed to the first wall panel 1 through the fixing rod 206. The drive motor 502 is then retracted to complete the assembly of the prefabricated self-resetting shock absorber connection structure.

[0048] The assembly of the prefabricated self-resetting shock-absorbing connection structure is achieved through a work frame, which is convenient, quick, time-saving, labor-saving, and more efficient.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
