Description

Technical Field

[0001] This invention relates to the field of prefabricated building technology, and in particular to a method for constructing high-strength multi-story prefabricated buildings. Background Technology

[0002] Prefabricated construction (also known as modular construction) is a construction method that involves prefabricating building components in a factory and then assembling them on the construction site. In prefabricated construction, beam-column connections are crucial structural elements, ensuring the stability and safety of the entire building. Compared to traditional cast-in-place construction, the amount of cast-in-place work is significantly reduced, thus improving construction efficiency.

[0003] Chinese invention patent CN111501999B discloses a method for connecting steel structure beams and columns in prefabricated buildings. The connection structure includes a column, a beam, and a steel connecting member. The column has embedded reinforcing bars, and the beam has embedded reinforcing bars. One end of the beam is connected to one side of the column through the steel connecting member. The steel connecting member includes a first connecting steel member and a second connecting steel member. The first connecting steel member is fixedly installed on the side wall of the column, and the second connecting steel member is fixedly installed on one end of the beam. Two pairs of internal threaded tube seats are embedded in the column. The interface of the internal threaded tube seats is flush with one side wall of the column. The first connecting steel member is integrally formed by the column connecting part and the support part. The column connecting part fits against the side wall of the column, and the column connecting part is connected to the internal threaded tube seats embedded in the column by screws.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: the first connecting steel component is fixed to the column with multiple screws for installing the crossbeam. When constructing multi-story prefabricated buildings, it is often necessary to install crossbeams on multiple side walls of the column. In the above solution, the component efficiency of the crossbeam and column is low. Therefore, it is necessary to design a connection structure between the crossbeam and column that is easy to install and disassemble quickly in order to improve the construction efficiency of multi-story prefabricated buildings. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a method for constructing high-strength multi-story prefabricated buildings.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a method for constructing a high-strength multi-story prefabricated building, comprising the following steps:

[0007] S1. The base column is used as the building support structure, and an annular connecting seat is fixedly fitted on the upper end of the base column; a snap-fit ​​part is provided on the outside of the annular connecting seat, and a connecting hook is fixed on the side wall of the base column near its upper end; a clearance opening communicating with the snap-fit ​​part is provided on the annular connecting seat, and a positioning opening is provided on the side of the connecting hook away from the base column.

[0008] S2. Place the crossbeam on the annular connecting seat. One end of the crossbeam is inserted into the snap-fit ​​part. The end of the crossbeam near the base column is provided with the snap-fit ​​part. After the connecting hook passes through the clearance opening, its top is inserted into the snap-fit ​​part.

[0009] S3. An elastic positioning component is installed on the crossbeam. The elastic positioning component is inserted into the positioning port on the connecting hook to achieve a stable connection between the crossbeam, the base column, and the annular connecting seat.

[0010] S4. The foundation assembly and connection of high-strength multi-story prefabricated buildings is completed through the cooperation of the base column, ring connecting seat, crossbeam and elastic positioning components.

[0011] By adopting the above technical solution, during installation, workers need to align the insertion part at the bottom of the beam with the connecting hook and insert it from top to bottom. This allows the elastic positioning component to engage with the positioning port on the connecting hook, ensuring a quick and stable connection between the beam, the base column, and the annular connecting seat. This changes the traditional design method of using multiple bolts for connection, eliminating the tedious operation of repeatedly tightening multiple bolts, improving the connection efficiency between the beam and the base column, and thus improving the construction efficiency of multi-story prefabricated buildings.

[0012] Furthermore, the crossbeam is a hollow square tube structure. The elastic positioning component includes a mounting cylinder fixed to the crossbeam near the insertion part, a clamping spring disposed inside the mounting cylinder, and a positioning rod connected to the end of the clamping spring near the base column. The mounting cylinder is located on the side of the insertion part away from the base column, and the end of the positioning rod away from the clamping spring is inserted into the positioning port.

[0013] Furthermore, the side of the connecting hook near the base column and the side of the insertion part near the base column are mutually cooperating first inclined surfaces, and the top of the connecting hook and the side of the connecting hook away from the base column, as well as the bottom of the positioning rod and the side of the positioning rod near the base column, are provided with mutually cooperating second inclined surfaces.

[0014] By adopting the above technical solution, when installing the crossbeam, the worker only needs to align the insertion part at the bottom of the crossbeam with the connecting hook and insert it from top to bottom. This allows the second inclined surface on the positioning rod to abut against the top of the connecting hook, causing the positioning rod to gradually retract into the installation cylinder and compress the clamping spring. When the positioning rod is inserted into the positioning port, the positioning rod returns to its original position under the action of the clamping spring and inserts into the positioning port. At this time, the insertion part at the bottom of the crossbeam is inserted into the connecting hook on the side wall of the base column, and one end of the crossbeam is inserted into the snap-fit ​​part on the annular connecting seat, thus realizing a quick and stable connection between the crossbeam, the base column, and the annular connecting seat.

[0015] Furthermore, a separation mechanism is provided inside the crossbeam. The separation mechanism includes a separation component, which includes a vertical rod rotatably mounted inside the crossbeam, a pulley fixedly sleeved on the vertical rod, a horizontal plate fixed to the inner wall of the crossbeam, a winding roller rotatably mounted on the bottom inner wall of the crossbeam, a movable plate disposed inside the crossbeam, a pressure block fixed to the top of the movable plate, a traction rope with one end fixed to the winding roller, and a first spring sleeved on the vertical rod and disposed between the bottom of the movable plate and the top of the horizontal plate. The vertical rod passes through the movable plate and the horizontal plate and slides in fit. A pressing port for the pressure block to pass through is provided at the top of the crossbeam. The end of the traction rope away from the winding roller passes around the pulley and through the end of the mounting cylinder away from the base column, and is fixed to the end of the positioning rod away from the base column. The separation mechanism also includes a transmission component for driving the winding roller to rotate during the descent of the pressure block.

[0016] By adopting the above technical solution, when it is necessary to disassemble the crossbeam, the worker only needs to press down the pressure block. The pressure block drives the winding roller to rotate through the transmission component, so that the end of the traction rope away from the positioning rod is gradually wound tightly on the winding roller. This causes the traction rope to pull the positioning rod and compress the clamping spring until the positioning rod separates from the positioning port. At this time, the worker can lift the crossbeam and separate the crossbeam from the annular connecting seat and the connecting hook, thus completing the disassembly of the crossbeam.

[0017] Furthermore, the transmission assembly includes a drive shaft fixed to the bottom of the movable plate, a winding roller sleeved on the drive shaft, and a helical drive block disposed inside the winding roller. The side wall of the drive shaft is provided with a helical groove that slides with the drive block.

[0018] By adopting the above technical solution, when the worker presses down the pressure block, the pressure block drives the movable plate and the drive shaft to move downward. Since the winding roller is rotated and installed on the inner bottom wall of the crossbeam, the winding roller is equipped with a spiral drive block, and the drive shaft is provided with a spiral groove that slides with the spiral drive block. This causes the winding roller to rotate during the downward movement of the drive shaft, thereby causing the end of the traction rope away from the positioning rod to gradually wind tightly on the winding roller.

[0019] Furthermore, multiple reinforcing plates are fixed inside the crossbeam, and through holes are provided on the reinforcing plates for the traction rope to pass through.

[0020] By adopting the above technical solution and setting multiple reinforcing plates, the structural strength and compressive strength of the square tubular beam are guaranteed during use.

[0021] Furthermore, the crossbeam is made of two semi-rectangular tubes that are mirror images of each other.

[0022] By adopting the above technical solution, it is easier for staff to install the separation mechanism.

[0023] Furthermore, a polygonal plug-in post is fixed to the upper end of the base column, and a plug-in hole is provided at the lower end of the base column for the plug-in post to be inserted into. Multiple mounting grooves are provided on the side wall of the base column near its lower end. The base column contains connecting holes that communicate with the top wall of the mounting grooves and receiving holes that communicate with both the plug-in hole and the connecting hole. The number of sides, mounting grooves, connecting holes, and receiving holes of the plug-in post are all equal. Multiple locking slots are provided on each side wall of the plug-in post. A crossbeam is provided on the base column for reinforcement. The reinforcing components that connect with the annular connecting seat have a number of sets corresponding to the number of sets of crossbeams and the number of mounting slots. The reinforcing components include a transmission gear that is rotatably installed in the receiving hole and meshes with the slot, a vertical rack that is set in the connecting hole and meshes with the transmission gear, a connecting diagonal rod that is fixed to the lower end of the vertical rack and located in the mounting slot, and a pressure plate that is fixed to the end of the connecting diagonal rod away from the vertical rack. The bottom of the pressure plate abuts against the top of the crossbeam near the connecting hook on the side away from the base column.

[0024] By adopting the above technical solution, when connecting the upper and lower base columns, the workers align the insertion post at the top of the lower base column with the insertion hole at the bottom of the upper base column. During the connection process between the insertion post and the insertion hole, multiple slots on the insertion post mesh with the transmission gear inside the upper base column, thereby driving multiple vertical racks to move downwards. This causes the connecting diagonal rod at the lower end of the vertical rack and the pressure plate at the end of the connecting diagonal rod away from the vertical rack to move downwards until the bottom of the pressure plate, away from the base column, abuts against the top of the crossbeam near the connecting hook. At this point, the upper end of the insertion post abuts against the top wall inside the insertion hole. The setting of the pressure plate plays a certain role in pressing and positioning the top of the crossbeam, which helps to ensure the stability of the crossbeam during use.

[0025] Furthermore, the upper end of the plug-in post is provided with an upper movable groove and a lower movable groove from top to bottom. The width of the lower movable groove is greater than the width of the upper movable groove. The plug-in post is provided with a locking component for connecting two adjacent base posts. The locking component includes a hook that slides with the upper movable groove, a sliding block that is fixed to the lower end of the hook and slides with the lower movable groove, and a second spring that is fixed to the side of the sliding block away from the transmission gear. The end of the second spring away from the transmission gear is fixed to the end of the lower movable groove away from the transmission gear. The base post is provided with a clearance groove that communicates with the top wall of the plug-in hole and allows the upper end of the hook to move. The base post is also provided with a hook groove for the upper end of the hook to engage.

[0026] By adopting the above technical solution, during the connection process between the plug-in column at the top of the lower base column and the plug-in hole at the bottom of the upper base column, the hook is abutted by the inner wall of the clearance groove near the crossbeam, causing the hook and sliding block to move towards the side away from the crossbeam, thereby gradually compressing the second spring. When the hook aligns with the hook groove, the hook resets under the action of the second spring and completes the connection and positioning with the hook groove, ensuring the connection effect between the plug-in column at the top of the lower base column and the plug-in hole at the bottom of the upper base column. At the same time, the side of the bottom of the pressure plate away from the base column abuts against the position of the top of the crossbeam near the connecting hook, ensuring the connection stability between the crossbeam, the base column, and the annular connecting seat, and ensuring the stability of the high-strength multi-layer prefabricated building structure composed of components such as the base column, crossbeam, and annular connecting seat during use.

[0027] Furthermore, the insertion post is provided with a vertical hole that communicates with the bottom wall of the lower movable groove and extends into the base post. The side wall of the insertion post is provided with a transverse hole that communicates with the vertical hole. The base post is provided with a quick-release assembly for controlling the separation of the hook and the hook groove. The quick-release assembly includes a threaded rod rotatably mounted on the bottom wall of the vertical hole, a push rod sleeved on the threaded rod and slidingly engaged with the vertical hole, a driven gear fixedly sleeved on the threaded rod, and a transverse rack provided in the transverse hole and meshing with the driven gear. The intersection between the bottom of the sliding block and the side of the sliding block near the transmission gear, as well as the upper end of the push rod, are provided with mutually cooperating third inclined surfaces. The lower end of the push rod is provided with a threaded hole for threaded connection of the threaded rod.

[0028] By adopting the above technical solution, when it is necessary to disassemble two adjacent base columns, the worker only needs to insert a thin rod through the through hole of the horizontal hole and make the thin rod push the horizontal rack, which will cause the horizontal rack to drive the driven gear to rotate, thereby causing the threaded rod fixed to the driven gear to rotate. Since the threaded rod is threadedly connected to the threaded hole at the bottom of the push rod, and the push rod is slidingly engaged with the vertical hole, the push rod moves upward. The third inclined surface at the top of the push rod acts on the sliding block at the bottom of the sliding block and drives the sliding block to slide along the lower movable groove until the hook separates from the hook groove. At this time, the worker can lift the upper base column upward and complete the disassembly of the two base columns.

[0029] In summary, the present invention has the following beneficial effects:

[0030] 1. This application changes the traditional design method of using multiple bolts for connection, eliminating the tedious operation of repeatedly tightening multiple bolts, improving the connection efficiency between beams and base columns, and thus improving the construction efficiency of multi-story prefabricated buildings.

[0031] 2. In this application, when it is necessary to disassemble the crossbeam, the worker only needs to press down the pressure block. The pressure block drives the winding roller to rotate through the transmission component, so that the end of the traction rope away from the positioning rod is gradually wound tightly on the winding roller, thereby causing the traction rope to pull the positioning rod and compress the clamping spring until the positioning rod separates from the positioning port. At this time, the worker can lift the crossbeam and separate the crossbeam from the annular connecting seat and the connecting hook, thus completing the disassembly of the crossbeam.

[0032] 3. In the process of connecting the plug-in column at the top of the lower base column to the plug-in hole at the bottom of the upper base column, the hook is abutted by the inner wall of the clearance groove near the crossbeam, causing the hook and sliding block to move towards the side away from the crossbeam, thereby gradually compressing the second spring. When the hook aligns with the hook groove, the hook resets under the action of the second spring and completes the connection and positioning with the hook groove, ensuring the connection effect between the plug-in column at the top of the lower base column and the plug-in hole at the bottom of the upper base column. At the same time, the side of the bottom of the pressure plate away from the base column abuts against the position of the top of the crossbeam near the connecting hook, ensuring the connection stability between the crossbeam, the base column, and the annular connecting seat, and ensuring the stability of the high-strength multi-layer prefabricated building structure composed of components such as the base column, crossbeam, and annular connecting seat during use.

[0044] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0045] like Figure 1-10 As shown in the figure, this application discloses a method for constructing a high-strength multi-story prefabricated building, including the following steps:

[0046] S1. The base column 1 is used as a building support structure. An annular connecting seat 2 is fixedly sleeved on the upper end of the base column 1. A snap-fit ​​part 21 is provided on the outside of the annular connecting seat 2. A connecting hook 3 is fixed on the side wall of the base column 1 near its upper end. A clearance opening 22 communicating with the snap-fit ​​part 21 is provided on the annular connecting seat 2. A positioning opening 31 is provided on the side of the connecting hook 3 away from the base column 1.

[0047] S2. The crossbeam 4 is placed on the annular connecting seat 2. One end of the crossbeam 4 is inserted into the snap-fit ​​part 21. The end of the crossbeam 4 near the base column 1 is provided with the snap-fit ​​part 41. After the connecting hook 3 passes through the relief opening 22, its top is inserted into the snap-fit ​​part 41.

[0048] S3. An elastic positioning component 5 is installed on the crossbeam 4. The elastic positioning component 5 is inserted into the positioning port 31 on the connecting hook 3 to achieve a stable connection between the crossbeam 4, the base column 1, and the annular connecting seat 2.

[0049] S4. The foundation assembly and connection of the high-strength multi-story prefabricated building is completed through the cooperation of the base column 1, the ring connecting seat 2, the crossbeam 4 and the elastic positioning component 5.

[0050] During installation, workers need to align the insertion part 41 at the bottom of the crossbeam 4 with the connecting hook 3 and insert it from top to bottom. This allows the elastic positioning component 5 to engage with the positioning port 31 on the connecting hook 3, ensuring a quick and stable connection between the crossbeam 4, the base column 1, and the annular connecting seat 2. This changes the traditional design method of using multiple bolts for connection, eliminating the tedious operation of repeatedly tightening multiple bolts and improving the connection efficiency between the crossbeam 4 and the base column 1, thereby improving the construction efficiency of multi-story prefabricated buildings.

[0051] The crossbeam 4 is a hollow square tube structure. The elastic positioning component 5 includes a mounting cylinder 51 fixed to the crossbeam 4 near the insertion part 41, a clamping spring 52 disposed inside the mounting cylinder 51, and a positioning rod 53 connected to the end of the clamping spring 52 near the base column 1. The mounting cylinder 51 is located on the side of the insertion part 41 away from the base column 1, and the end of the positioning rod 53 away from the clamping spring 52 is inserted into the positioning port 31. The side of the connecting hook 3 near the base column 1 and the side of the insertion part 41 near the base column 1 are mutually cooperating first inclined surfaces 6. The top of the connecting hook 3 and the side of the connecting hook 3 away from the base column 1, and the bottom of the positioning rod 53 and the side of the positioning rod 53 near the base column 1 are provided with mutually cooperating second inclined surfaces 7.

[0052] When installing the crossbeam 4, the worker only needs to align the insertion part 41 at the bottom of the crossbeam 4 with the connecting hook 3 and insert it from top to bottom. This causes the second inclined surface 7 on the positioning rod 53 to abut against the top of the connecting hook 3, thereby causing the positioning rod 53 to gradually retract into the mounting cylinder 51 and compress the clamping spring 52. When the positioning rod 53 is inserted into the positioning port 31, the positioning rod 53 is reset under the action of the clamping spring 52 and inserted into the positioning port 31. At this time, the insertion part 41 at the bottom of the crossbeam 4 is inserted into the connecting hook 3 on the side wall of the base column 1, and one end of the crossbeam 4 is inserted into the snap-fit ​​part 21 on the annular connecting seat 2, realizing a quick and stable connection between the crossbeam 4, the base column 1, and the annular connecting seat 2.

[0053] A separation mechanism 8 is provided inside the crossbeam 4. The separation mechanism 8 includes a separation component 81, which includes a vertical rod 811 rotatably mounted inside the crossbeam 4, a pulley 812 fixedly sleeved on the vertical rod 811, a horizontal plate 813 fixed to the inner wall of the crossbeam 4, a winding roller 814 rotatably mounted on the inner bottom wall of the crossbeam 4, a movable plate 815 disposed inside the crossbeam 4, a pressure block 816 fixed to the top of the movable plate 815, a traction rope 817 with one end fixed to the winding roller 814, and a component sleeved on the vertical rod 811 and disposed on the horizontal plate 813. A first spring 818 is located between the bottom of the movable plate 815 and the top of the horizontal plate 813; a vertical rod 811 passes through the movable plate 815 and the horizontal plate 813 and is slidably engaged; a pressing port 42 is provided at the top of the crossbeam 4 for the pressure block 816 to pass through; one end of the traction rope 817 away from the winding roller 814 passes around the pulley 812 and through the end of the mounting cylinder 51 away from the base column 1, and is fixed to the end of the positioning rod 53 away from the base column 1; the separation mechanism 8 also includes a transmission assembly 82 for driving the winding roller 814 to rotate during the descent of the pressure block 816.

[0054] When it is necessary to disassemble the crossbeam 4, the worker only needs to press down the pressure block 816. The pressure block 816 drives the winding roller 814 to rotate through the transmission component 82, so that the end of the traction rope 817 away from the positioning rod 53 is gradually wound tightly on the winding roller 814. This causes the traction rope 817 to pull the positioning rod 53 and compress the clamping spring 52 until the positioning rod 53 separates from the positioning port 31. At this time, the worker can lift the crossbeam 4 and separate the crossbeam 4 from the annular connecting seat 2 and the connecting hook 3, thus completing the disassembly of the crossbeam 4.

[0055] The transmission assembly 82 includes a drive shaft 821 fixed to the bottom of the movable plate 815, a winding roller 814 sleeved on the drive shaft 821, and a spiral drive block 822 disposed inside the winding roller 814. The side wall of the drive shaft 821 is provided with a spiral groove 8211 that slides with the drive block.

[0056] When the worker presses down the pressure block 816, the pressure block 816 drives the movable plate 815 and the drive shaft 821 to move downward. Since the winding roller 814 is rotatably installed on the inner bottom wall of the crossbeam 4, and the winding roller 814 is provided with a spiral drive block 822, and the drive shaft 821 is provided with a spiral groove 8211 that slides with the spiral drive block 822, the winding roller 814 rotates during the downward movement of the drive shaft 821, thereby causing the end of the traction rope 817 away from the positioning rod 53 to gradually wind tightly on the winding roller 814.

[0057] To ensure the structural strength of the crossbeam 4 during use, multiple reinforcing plates 43 are fixed inside the crossbeam 4. Through holes (not shown in the figure) are provided on the reinforcing plates 43 for the traction rope 817 to pass through. To facilitate the installation of the separation mechanism 8 by workers, the crossbeam 4 is composed of two semi-rectangular tubes with mirror-like structures connected together (the two semi-rectangular tubes can be connected using common fixing methods such as welding, or detachable connection methods such as bolts).

[0058] A polygonal plug-in post 10 is fixed to the upper end of the base column 1. A plug-in hole 11 for the plug-in post 10 to be plugged into is provided at the lower end of the base column 1. Multiple mounting grooves 12 are provided on the side wall of the base column 1 near its lower end. A connecting hole 13 communicating with the top wall of the mounting groove 12 and a receiving hole 14 communicating with both the plug-in hole 11 and the connecting hole 13 are provided inside the base column 1. The number of sides of the plug-in post 10, the number of mounting grooves 12, the number of connecting holes 13, and the number of receiving holes 14 are all equal. Multiple slots 101 are provided on each side wall of the plug-in post 10. The base column 1 is provided with a device for reinforcing the crossbeam 4 and the annular... The reinforcing components 9 that connect the connecting seats 2 are arranged in a one-to-one correspondence with the number of sets of crossbeams 4 and the number of mounting slots 12. The reinforcing components 9 include a transmission gear 91 that is rotatably installed in the receiving hole 14 and meshes with the slot 101, a vertical rack 92 that is set in the connecting hole 13 and meshes with the transmission gear 91, a connecting diagonal rod 93 that is fixed to the lower end of the vertical rack 92 and located in the mounting slot 12, and a pressure plate 94 that is fixed to the end of the connecting diagonal rod 93 away from the vertical rack 92. The bottom side of the pressure plate 94 away from the base column 1 abuts against the top of the crossbeam 4 near the connecting hook 3.

[0059] When connecting the upper and lower base columns 1, the worker aligns the insertion post 10 at the top of the lower base column 1 with the insertion hole 11 at the bottom of the upper base column 1. During the connection process between the insertion post 10 and the insertion hole 11, multiple slots 101 on the insertion post 10 mesh with the transmission gear 91 inside the upper base column 1, thereby driving multiple vertical racks 92 to move downward. This causes the connecting diagonal rod 93 at the lower end of the vertical rack 92 and the pressure plate 94 at the end of the connecting diagonal rod 93 away from the vertical rack 92 to move downward until the bottom of the pressure plate 94 away from the base column 1 abuts against the top of the crossbeam 4 near the connecting hook 3. At this point, the upper end of the insertion post 10 abuts against the inner top wall of the insertion hole 11. The setting of the pressure plate 94 plays a certain role in pressing and positioning the top of the crossbeam 4, which helps to ensure the stability of the crossbeam 4 during use.

[0060] The upper end of the plug-in post 10 is provided with an upper movable groove 102 and a lower movable groove 103 from top to bottom. The width of the lower movable groove 103 is greater than the width of the upper movable groove 102. The plug-in post 10 is provided with a locking component 15 for connecting two adjacent base posts 1. The locking component 15 includes a hook 151 that slides with the upper movable groove 102, a sliding block 152 that is fixed to the lower end of the hook 151 and slides with the lower movable groove 103, and a second spring 153 that is fixed to the side of the sliding block 152 away from the transmission gear 91. The end of the second spring 153 away from the transmission gear 91 is fixed to the end of the lower movable groove 103 away from the transmission gear 91. The base post 1 is provided with a clearance groove 16 that communicates with the inner top wall of the plug-in hole 11 and allows the upper end of the hook 151 to move. The base post 1 is also provided with a hook groove 17 for the upper end of the hook 151 to engage.

[0061] During the connection process between the insertion post 10 at the top of the lower base column 1 and the insertion hole 11 at the bottom of the upper base column 1, the hook 151 is abutted by the inner wall of the clearance groove 16 near the side of the crossbeam 4, causing the hook 151 and the sliding block 152 to move towards the side away from the crossbeam 4, thereby gradually compressing the second spring 153. When the hook 151 corresponds to the hook groove 17, the hook 151 is reset under the action of the second spring 153 and completes the connection and positioning with the hook groove 17, ensuring the connection effect between the insertion post 10 at the top of the lower base column 1 and the insertion hole 11 at the bottom of the upper base column 1. At the same time, the bottom of the pressure plate 94 away from the base column 1 abuts against the top of the crossbeam 4 near the connecting hook 3, ensuring the connection stability between the crossbeam 4, the base column 1, and the annular connecting seat 2, and ensuring the stability of the high-strength multi-layer prefabricated building structure composed of components such as the base column 1, the crossbeam 4, and the annular connecting seat 2 during use.

[0062] The insertion post 10 is provided with a vertical hole 18 that communicates with the bottom wall of the lower movable groove 103 and extends into the base post 1. The side wall of the insertion post 10 is provided with a transverse hole 19 that communicates with the vertical hole 18. The base post 1 is provided with a quick-release assembly 20 for controlling the separation of the hook 151 and the hook groove 17. The quick-release assembly 20 includes a threaded rod 201 rotatably mounted on the bottom wall of the vertical hole 18, a push rod 202 sleeved on the threaded rod 201 and slidingly engaged with the vertical hole 18, a driven gear 203 fixedly sleeved on the threaded rod 201, and a transverse rack 204 provided in the transverse hole 19 and meshing with the driven gear 203. The bottom of the sliding block 152 and the side of the sliding block 152 near the transmission gear 91 are provided with mutually cooperating third inclined surfaces 1521. The lower end of the push rod 202 is provided with a threaded hole for threaded connection of the threaded rod 201.

[0063] When it is necessary to disassemble two adjacent base columns 1, the worker only needs to insert a thin rod through the through hole of the transverse hole 19 and make the thin rod push the transverse rack 204, which will cause the transverse rack 204 to drive the driven gear 203 to rotate, thereby causing the threaded rod 201 fixed to the driven gear 203 to rotate. Since the threaded rod 201 is threadedly connected to the threaded hole at the bottom of the push rod 202, and the push rod 202 is slidably engaged with the vertical hole 18, the push rod 202 moves upward. The third inclined surface 1521 at the top of the push rod 202 acts on the sliding block 152 at the bottom of the sliding block 152 and drives the sliding block 152 to slide along the lower movable groove 103 until the hook 151 separates from the hook groove 17. At this time, the worker can lift the upper base column 1 upward and complete the disassembly of the two base columns 1.
