Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated buildings, and particularly to an efficient connection node structure and construction technology for prefabricated buildings. Background Art

[0002] Prefabricated buildings have become an important direction of building industrialization due to advantages such as industrial production, short construction period, and environmental friendliness. The core lies in the efficient connection of precast components, and the rationality of node design directly affects structural safety, seismic performance, and construction efficiency.

[0003] Currently, the connection methods of prefabricated buildings are divided into wet connection, dry connection, and hybrid connection. Wet connection mainly uses grouting sleeves and grout anchor lapping, relying on concrete filling to achieve mechanical transmission, but it has problems such as long construction period and quality inspection. Dry connection can be implemented by bolts, welding, or mechanical buckles, which is relatively convenient for construction but has limited seismic performance. Combining grouting and mechanical fixing, such as welding of embedded steel plates + high-strength bolts, can improve the reliability of the node.

[0004] In the patent document with the publication number CN118187294B that has been made public, a special-shaped column node connection structure for prefabricated buildings is disclosed, including a special-shaped column and a cross beam. The cross beam is fixed on the surface of the special-shaped column through a reinforcement plate. In the present invention, the reinforcement plate is pre-installed on the special-shaped column and the cross beam through a positioning rod, and then the reinforcement plate is installed between the special-shaped column and the cross beam through bolts. Then, the positioning component is pushed by the continuous movement of the positioning rod to lock and clamp the bolts. When the bolts are subjected to external vibration, the bolts will not be displaced, ensuring the stable installation of the reinforcement plate on the special-shaped column and the cross beam, avoiding the risk of bolt loosening or even falling off, and increasing the safety during the construction process.

[0005] When the above device is in use, the positioning component needs to be installed strictly according to the specified depth, which is beneficial to the stability after assembly. Especially after grouting, it is difficult to make secondary changes to the positioning component. Therefore, if the pre-installation depth of the positioning component is relatively deep, the installation of the bolts will be restricted by the positioning component, interfering with the disassembly and assembly of the positioning rod. If the pre-installation depth of the positioning component is relatively shallow, the bolts will not be installed in place, easily causing the bolts to be deformed under pressure in the later stage.

[0006] Therefore, this application proposes an efficient connection node structure and construction technology for prefabricated buildings. Summary of the Invention

[0007] The object of the present invention is to address the problem that the installation of the positioning component in the background art leads to the problem that the bolt rod is not installed in place or the installation is interfered, and to propose an efficient connection node structure and construction technology for prefabricated buildings.

[0008] On the one hand, the present application provides an efficient connection node structure for prefabricated buildings, including a prefabricated special-shaped column.

A plurality of second guiding holes are formed on the surface of the connection guide plate, and a plurality of first guiding holes are formed on the surface of the auxiliary positioning plate. The second guiding holes and the first guiding holes are arranged in an aligned state. An auxiliary positioning rod is installed in the middle second guiding hole and the first guiding hole by threading; The clamping positioning component includes a positioning column fixedly installed at the bottom of the auxiliary positioning rod. A telescopic support column is fixedly installed at the bottom of the positioning column. Two groups of second guiding inclined rods are hinged on the outside of the positioning column. Two groups of first guiding inclined rods are hinged on the outside of the telescopic support column. The first guiding inclined rod and the second guiding inclined rod are hinged to each other. One side of the first guiding inclined rod away from the telescopic support column is hinged with a clamping push rod.

[0009] Optionally, threaded rods are installed in the remaining second guiding holes and the first guiding holes by threading. The strengthening positioning component is installed on the outside of the prefabricated special-shaped column through the positioning component and the clamping positioning component.

[0010] Optionally, an airbag block is fixedly installed in the inner cavity of the auxiliary positioning plate. The clamping push rod is attached to the outside of the airbag block. A corresponding spring column is fixedly installed between the telescopic support column and the positioning column.

[0011] Optionally, an external sleeve block is fixedly installed on the outside of the clamping push rod. Two groups of auxiliary springs are fixedly installed between the external sleeve block and the clamping push rod.

[0012] Optionally, a clamping connection component is installed on the outside of the prefabricated special-shaped column. The clamping connection component includes two clamping auxiliary frames wrapped around the outside of the prefabricated special-shaped column.

[0013] Optionally, an internal threaded sleeve is fixedly installed inside one of the clamping auxiliary frames. An external threaded sleeve is threadedly connected inside the internal threaded sleeve. A threaded push rod is installed in the external threaded sleeve by threading.

[0014] Optionally, a chute tube is fixedly installed on the inner wall of the external thread sleeve, a pushing card plate is slidably installed on the inner wall of the chute tube, a guiding card cavity rod is fixedly installed inside the pushing card plate, a card slot is formed in the inner wall of the guiding card cavity rod, and one side of the thread pushing rod extending into the guiding card cavity rod is rotatably installed on the inner wall of the guiding card cavity rod through the card slot.

[0015] Optionally, two groups of bidirectional hinge rods are hinged inside the guiding card cavity rod, an auxiliary spring is fixedly installed between the bidirectional hinge rod and the guiding card cavity rod, and a positioning push plate is fixedly installed on the side of the bidirectional hinge rod away from the guiding card cavity rod.

[0016] Optionally, a threaded connection pipe is installed inside the other clamping auxiliary frame in a threaded manner, four limiting clamping components are fixedly installed inside the threaded connection pipe, a hollow inclined block is fixedly installed on the inner walls of the four limiting clamping components, an external threaded pipe is arranged on one side where the external thread sleeve passes through the internal thread sleeve, and the external threaded pipe is threadedly installed inside the threaded connection pipe.

[0017] On the other hand, the present application provides a construction process for an efficient connection node structure of prefabricated buildings, including the following steps: S1: First, check the dimensions of the prefabricated special-shaped column, the strengthening positioning component, the positioning component and the clamping connection component. It is required that the embedding position accuracy of the prefabricated special-shaped column meets the standard and the performance of the grouting material reaches the standard. Check the specification and design matching of the connecting piece clamping connection component, the threaded rod, the auxiliary positioning rod and the clamping positioning component, and use an endoscope to check the through holes of the prefabricated special-shaped column, the strengthening positioning component and the positioning component; S2: When connecting the periphery of the prefabricated special-shaped column with other components, first install the internal thread sleeve of one of the clamping auxiliary frames on the external thread sleeve through a threaded knob, and rotate and install the threaded connection pipe inside the other clamping auxiliary frame to a fixed position. The two clamping auxiliary frames wrap the outside of the prefabricated special-shaped column, and the threaded connection pipe is rotated through the external thread to the inside of the threaded connection pipe to complete the preliminary positioning installation; S3: Then manually rotate the thread pushing rod. The thread pushing rod rotates and pushes the guiding card cavity rod to move outwards along the inside of the external thread sleeve. The positioning push plate drives the bidirectional hinge rod to deflect outwards along the guiding card cavity rod under the thrust of the hollow inclined block, and the bidirectional hinge rod drives the positioning push plate to snap into the empty slot of the limiting clamping component. When the positioning push plate fully provides a supporting force to the side wall of the limiting clamping component, the installation is completed; S4: When the auxiliary positioning rod moves to the specified position, the connecting guide plate and the auxiliary positioning plate are aligned hole to hole due to the side wall thrust of the auxiliary positioning rod along the first guiding hole and the second guiding hole. The telescopic support column continues to move towards the inside of the auxiliary positioning plate. The telescopic support column is received into the inside of the positioning column through the corresponding spring column. The telescopic support column drives the two groups of first guiding inclined rods to move upward, and the first guiding inclined rods then push the clamping push rod outward to complete the installation of the auxiliary positioning rod. S5: When the auxiliary positioning plate and the connecting guide plate are completely in the hole-to-hole positioning state, the staff then turns the threaded rod to complete the splicing and installation of the strengthening positioning component and the assembled special-shaped column.

[0018] In summary, the present application includes at least one of the following beneficial technical effects: 1. The telescopic support column can be received into the positioning column, avoiding the reverse force of the second guiding hole during installation from causing thread slipping or deformation. When the staff continues to apply force, the force between the bottom of the auxiliary positioning rod and the side wall of the auxiliary positioning plate is elastically buffered by the airbag block, thereby further reducing the adverse effects caused by situations such as excessive turning of the positioning rod. 2. When the assembled component is subjected to an external impact, the clamping push rod increases the friction with the airbag block and also uses the external impact of the airbag block for buffering, thereby improving the stability of the assembled component. And because the clamping push rod is in close contact with the airbag block, if a tensile force occurs in the direction of the auxiliary positioning rod for the assembled special-shaped column, the clamping push rod uses the elastic force of the auxiliary spring for buffering in the case of being in contact with the airbag block, so that the positioning component is relatively stable when dealing with forces in all directions and its service life is extended. 3. Multiple limit clamping components and the positioning push plate form a circular shape, enabling the positioning push plate to fully provide a supporting force to the side walls of the limit clamping components, improving the stability during the installation of the connecting piece, so that when the two connecting rods are connected, the two connecting rods will not become disconnected due to vibration. And the hollow inclined block, the guiding cavity rod, the positioning push plate and the limit clamping components form a relatively sealed state, thereby reducing the risk of oxidation inside the connecting component.

Detailed implementation manners

[0021] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] As Figures 1-4As shown in the figure, an efficient connection node structure for prefabricated buildings proposed by the present invention includes a prefabricated special-shaped column 1. One side of the prefabricated special-shaped column 1 is provided with a strengthening positioning component 2 for strengthening the connection node through a positioning component 3. A plurality of positioning components 3 are provided according to requirements, so as to increase the stability between the strengthening positioning component 2 and the prefabricated special-shaped column 1. The strengthening positioning component 2 includes a U-shaped cavity plate 202, and a strengthening plate 201 is welded on one side of the U-shaped cavity plate 202. The positioning component 3 includes a connection guide plate 301 attached to the outside of the strengthening plate 201. An auxiliary positioning plate 302 is attached to the outside of the prefabricated special-shaped column 1. The auxiliary positioning plate 302 is inserted into the inside of the strengthening plate 201. A plurality of second guiding holes 306 are formed on the surface of the connection guide plate 301, and a plurality of first guiding holes 304 are formed on the surface of the auxiliary positioning plate 302. The second guiding holes 306 and the first guiding holes 304 are arranged in an aligned state. An auxiliary positioning rod 307 is threadedly installed in the second guiding hole 306 and the first guiding hole 304 in the middle, and a threaded rod 305 is threadedly installed in the remaining second guiding holes 306 and the first guiding holes 304.

[0023] Furthermore, it should be noted that a clamping and positioning component 5 for positioning is installed inside the positioning component 3. The strengthening positioning component 2 is installed on the outside of the prefabricated special-shaped column 1 through the positioning component 3 and the clamping and positioning component 5. Among them, the clamping and positioning component 5 includes a positioning column 501 fixedly installed at the bottom of the auxiliary positioning rod 307. A telescopic support column 503 is fixedly installed at the bottom of the positioning column 501. Two groups of second guiding inclined rods 508 are hinged on the outside of the positioning column 501. A limiting sleeve is fixedly installed at the connection between the positioning column 501 and the second guiding inclined rod 508 to limit the deflection angle of the second guiding inclined rod 508. Two groups of first guiding inclined rods 504 are hinged on the outside of the telescopic support column 503. The first guiding inclined rod 504 and the second guiding inclined rod 508 are arranged in a hinged state. A clamping push rod 505 is hinged on the side of the first guiding inclined rod 504 away from the telescopic support column 503. A corresponding spring column 502 is fixedly installed between the telescopic support column 503 and the positioning column 501. The corresponding spring column 502 limits the distance for the telescopic support column 503 to be retracted into the positioning column 501, and at the same time provides elastic force for the first guiding inclined rod 504, the second guiding inclined rod 508 and the telescopic support column 503 to return to their original positions without external force.

[0024] Furthermore, an airbag block 303 is fixedly installed inside the inner cavity of the auxiliary positioning plate 302. The clamping push rod 505 is attached to the outer side of the airbag block 303. An external sleeve block 506 is fixedly installed on the outer side of the clamping push rod 505. Two groups of auxiliary springs 507 are fixedly installed between the external sleeve block 506 and the clamping push rod 505. The staff fits and inserts the U-shaped empty groove of the reinforcing plate 201 with the U-shaped convex block of the auxiliary positioning plate 302 to facilitate the hole-to-hole positioning between the first guide hole 304 and the second guide hole 306. When the first guide hole 304 in the middle is relatively close to the second guide hole 306, it first drives the auxiliary positioning rod 307 to move along the threads inside the second guide hole 306 and the first guide hole 304 towards the position of the assembled special-shaped column 1. When the first guide inclined rod 504 and the second guide inclined rod 508 are in the normal state, that is, when the auxiliary positioning rod 307 has not penetrated into the fixed depth inside the auxiliary positioning plate 302, the second guide inclined rod 508 and the first guide inclined rod 504 are attached to the outer sides of the positioning column 501 and the telescopic support column 503. The distance between the first guide inclined rod 504 and the second guide inclined rod 508 towards the vertical center line of the telescopic support column 503 is smaller than the radius of the auxiliary positioning rod 307. Then the components below the positioning column 501 can smoothly pass through the inside of the auxiliary positioning plate 302; When the auxiliary positioning rod 307 moves to the specified position, the connecting guide plate 301 and the auxiliary positioning plate 302 are aligned hole-to-hole due to the side wall thrust of the auxiliary positioning rod 307 moving along the first guide hole 304 and the second guide hole 306. At the same time, as the telescopic support column 503 continues to move towards the inside of the auxiliary positioning plate 302, the telescopic support column 503 is received into the inside of the positioning column 501 through the corresponding spring column 502. Since the second guide inclined rods 508 on both sides of the positioning column 501 are limited, the telescopic support column 503 drives the two groups of first guide inclined rods 504 to move upward. The first guide inclined rod 504 then pushes the clamping push rod 505 to move outward. The clamping push rod 505 gives an external pressure to the airbag block 303. Then when the assembled component is impacted externally, the clamping push rod 505 increases the friction with the airbag block 303 and also uses the external impact of the airbag block 303 to achieve buffering, thereby improving the stability of the assembled component. And because the clamping push rod 505 is closely attached to the airbag block 303, if there is a pulling force on the assembled special-shaped column 1 in the direction of the auxiliary positioning rod 307, the clamping push rod 505 uses the elastic force of the auxiliary spring 507 for buffering in the case of being attached to the airbag block 303. Thus, the positioning component is relatively stable when dealing with forces in all directions, and its service life is extended.

[0025] In order to tighten the thread, the staff usually need to turn one more circle after installing the screw rod. As the main support component, the positioning rod is prone to thread slipping or deformation after excessive turning, resulting in the offset of the installation positions of the connecting guide plate 301 and the auxiliary positioning plate 302, and also causing deviation when the threaded rod 305 rotates. After the auxiliary positioning rod 307 rotates to a fixed depth, if it continues to rotate, the telescopic support column 503 can be received into the positioning column 501 to avoid thread slipping or deformation caused by the reaction force of the second guiding hole 306 during installation. When the staff continue to apply force, the force between the bottom of the auxiliary positioning rod 307 and the side wall of the auxiliary positioning plate 302 is elastically buffered by the airbag block 303, thereby further reducing the adverse effects caused by excessive turning of the positioning rod and other situations.

[0026] With the installation of the auxiliary positioning rod 307 completed, the auxiliary positioning plate 302 and the connecting guide plate 301 are completely in a hole-to-hole positioning state at this time. The staff then turn the threaded rod 305 to complete the splicing installation of the strengthening positioning component 2 and the assembled special-shaped column 1.

[0027] As Figures 5-11As shown in the figure, a clamping connection assembly 4 is installed on the outer side of the prefabricated special-shaped column 1. The clamping connection assembly 4 includes two clamping auxiliary frames 401 wrapped around the outer side of the prefabricated special-shaped column 1. An internal threaded sleeve 404 is fixedly installed inside one clamping auxiliary frame 401. An external threaded sleeve 405 is threadedly connected inside the internal threaded sleeve 404. A threaded push rod 406 is threadedly installed inside the external threaded sleeve 405. A chute tube 407 is fixedly installed on the inner wall of the external threaded sleeve 405. A push card plate 408 is slidably installed on the inner wall of the chute tube 407. A guide card cavity rod 409 is fixedly installed inside the push card plate 408. A card slot is opened on the inner wall of the guide card cavity rod 409. One side of the threaded push rod 406 extending into the guide card cavity rod 409 is rotatably installed on the inner wall of the guide card cavity rod 409 through the card slot. Two groups of double-ended articulated rods 411 are articulated inside the cavity of the guide card cavity rod 409. An auxiliary spring is fixedly installed between the double-ended articulated rod 411 and the guide card cavity rod 409. A positioning push plate 412 is fixedly installed on the side of the double-ended articulated rod 411 away from the guide card cavity rod 409. Four limiting clamping components 413 are threadedly installed inside the other clamping auxiliary frame 401. A hollow inclined block 410 is fixedly installed on the inner walls of the four limiting clamping components 413. An external threaded tube 402 is provided on the side where the external threaded sleeve 405 passes through the internal threaded sleeve 404. The external threaded tube 402 is threadedly installed inside the threaded connection tube 403. The prefabricated special-shaped column 1 is a component that needs to be grouted later, and higher requirements are placed on the embedding position accuracy and stability. When the prefabricated special-shaped column 1 is connected to other components on its circumferential side, first, the internal threaded sleeve 404 of one clamping auxiliary frame 401 is installed with the external threaded sleeve 405 through a threaded knob. Sealing sleeves for improving connection tightness and limiting are fixedly installed on the outer sides of the external threaded sleeve 405, the threaded push rod 406, and the internal threaded sleeve 404. The external threaded sleeve 405 is limited to a fixed distance inside the internal threaded sleeve 404 through the limiting knob between the sealing sleeves. Then, the threaded connection tube 403 is installed inside the other clamping auxiliary frame 401 by turning the knob to a fixed position. The two clamping auxiliary frames 401 wrap around the outer side of the prefabricated special-shaped column 1. The threaded connection tube 403 is rotated through the external thread to the inside of the threaded connection tube 403. It should be noted here that a threaded tube is fixedly installed on the side of the threaded connection tube 403 facing the external threaded tube 402, completing the preliminary positioning installation.

[0028] Next, manually rotate the threaded push rod 406. The threaded push rod 406 rotates along the inside of the external threaded sleeve 405 to push the guide and card cavity rod 409 to move outward. The guide and card cavity rod 409 is inserted into the inside of the hollow inclined block 410, improving the stability between the external threaded pipe 402 and the threaded connection pipe 403. As the positioning push plate 412 enters the inside of the threaded connection pipe 403, the bottom of the positioning push plate 412 is guided by the arc-shaped surface on the outside of the hollow inclined block 410. The positioning push plate 412 is driven by the thrust of the hollow inclined block 410 to drive the double-direction articulated rod 411 to deflect outward along the guide and card cavity rod 409. The double-direction articulated rod 411 drives the positioning push plate 412 to be stuck into the empty slot of the limit clamping assembly 413. Here, it should be noted that multiple limit clamping assemblies 413 and the positioning push plate 412 form a circular shape, causing the positioning push plate 412 to fully provide a supporting force to the side wall of the limit clamping assembly 413, improving the stability during the installation of the connecting piece. When the two connecting rods are connected, the two connecting rods will not become disconnected due to vibration. Moreover, the hollow inclined block 410, the guide and card cavity rod 409, the positioning push plate 412, and the limit clamping assembly 413 form a relatively sealed state, thereby reducing the risk of oxidation inside the connecting assembly.

[0029] On the other hand, the present application provides a construction process for an efficient connection node structure of a prefabricated building, including the following steps: S1: First, check the dimensions of the prefabricated special-shaped column 1, the strengthening positioning assembly 2, the positioning assembly 3, and the clamping connection assembly 4. It is required that the embedding position accuracy of the prefabricated special-shaped column 1 meets the standard and the performance of the grouting material reaches the standard. Check the specification and design matching of the connecting piece clamping connection assembly 4, the threaded rod 305, the auxiliary positioning rod 307, and the clamping and positioning assembly 5, and use an endoscope to check the through holes of the prefabricated special-shaped column 1, the strengthening positioning assembly 2, and the positioning assembly 3; S2: When connecting the periphery of the prefabricated special-shaped column 1 to other components, first install the internal threaded sleeve 404 of one of the clamping auxiliary frames 401 to the external threaded sleeve 405 through a threaded knob, and install the threaded connection pipe 403 inside the other clamping auxiliary frame 401 to a fixed position by rotating the knob. The two clamping auxiliary frames 401 wrap around the outside of the prefabricated special-shaped column 1, and the threaded connection pipe 403 is rotated through the external thread to the inside of the threaded connection pipe 403 to complete the preliminary positioning installation; S3: Then, manually rotate the threaded push rod 406. The threaded push rod 406 rotates along the inside of the external threaded sleeve 405 to push the guide and card cavity rod 409 to move outward. The positioning push plate 412 is driven by the thrust of the hollow inclined block 410 to drive the double-direction articulated rod 411 to deflect outward along the guide and card cavity rod 409. The double-direction articulated rod 411 drives the positioning push plate 412 to be stuck into the empty slot of the limit clamping assembly 413. When the positioning push plate 412 fully provides a supporting force to the side wall of the limit clamping assembly 413, the installation is completed; S4: When the auxiliary positioning rod 307 moves to the specified position, the connecting guide plate 301 and the auxiliary positioning plate 302 are aligned hole-to-hole due to the side wall thrust of the auxiliary positioning rod 307 along the first guide hole 304 and the second guide hole 306. The telescopic support column 503 continues to move towards the inside of the auxiliary positioning plate 302. The telescopic support column 503 is received into the inside of the positioning column 501 through the corresponding spring column 502. The telescopic support column 503 drives the two groups of first guide inclined rods 504 to move upward, and the first guide inclined rods 504 then push the clamping push rod 505 to move outward to complete the installation of the auxiliary positioning rod 307. S5: When the auxiliary positioning plate 302 and the connecting guide plate 301 are completely in the hole-to-hole positioning state, the staff then turns the threaded rod 305 to complete the splicing installation of the enhanced positioning component 2 and the assembled special-shaped column 1.

10. A construction process for an efficient connection node structure of an assembled building, using an efficient connection node structure of an assembled building as claimed in claim 9, characterized in that: The following steps are involved: S1: Check the dimensions of assembled special-shaped columns, reinforced positioning components, positioning components and clamping connection components, require that the embedded position accuracy of assembled special-shaped columns meets the standards and the performance of grouting materials meets the standards, check the specifications and design matching of the connector clamping connection components, threaded rods, auxiliary positioning rods and snap-fit ​​positioning components, and use an endoscope to perform through-hole inspections on assembled special-shaped columns, reinforced positioning components and positioning components; S2: When the peripheral side of the assembled special-shaped column is connected to other components, first install the external threaded sleeve through the threaded knob on the internal threaded sleeve of one of the clamping auxiliary frames, and install the threaded connection pipe to a fixed position through the internal knob of the other clamping auxiliary frame. The two clamping auxiliary frames wrap the outer side of the assembled special-shaped column, and the threaded connection pipe is rotated to the inside of the threaded connection pipe through the outer thread to complete the initial positioning installation; S3: Then manually rotate the threaded push rod, and the threaded push rod moves outward along the internal rotation push guide cavity rod of the external threaded sleeve. The positioning push plate is pushed by the hollow inclined block to drive the bidirectional hinged rod to deflect outward along the guide cavity rod, and the bidirectional hinged rod drives the positioning push plate to be clamped into the empty groove of the limit clamping assembly. The positioning push plate fully provides support force to the side wall of the limit clamping assembly to complete the installation; S4: When the auxiliary positioning rod moves to the specified position, the connecting guide plate and the auxiliary positioning plate are aligned with each other due to the side wall thrust of the auxiliary positioning rod along the first guide hole and the second guide hole, and the telescopic support column continues to move toward the inside of the auxiliary positioning plate. The telescopic support column is stored in the inside of the positioning column through the corresponding spring column, and the telescopic support column drives the two sets of first guide tilting rods to move upward, and the first guide tilting rod further pushes the clamping push rod to move outward, completing the installation of the auxiliary positioning rod; S5: When the auxiliary positioning plate and the connecting guide plate are completely in the hole-to-hole positioning state, the staff then turns the knob threaded rod to complete the splicing and installation of the reinforced positioning assembly and the assembled special-shaped column.
