Description

Technical Field

[0001] The invention relates to the technical field of assembled buildings, in particular to an assembled building connection component. Background Art

[0002] Prefabricated building connection components are key components in prefabricated building technology. They are responsible for connecting prefabricated building components such as beams, slabs and columns to form a stable structural system. The current common connection method is to connect prefabricated components with bolts and nuts.

[0003] An integral connection system for a reinforced concrete prefabricated building is disclosed in Chinese patent publication number CN110130502B. The integral connection system for a reinforced concrete prefabricated building connects the embedded plates of the beams with the embedded plates of the upper columns by means of bolts and nuts, and then hoists the floor slabs and the floor slabs at the junction of the beams and columns to form a stable structural system.

[0004] However, compared with the existing technologies in related fields, firstly, bolt connections usually require on-site tightening of bolts one by one, and require the use of corresponding tools, such as wrenches or electric screwdrivers, etc., which results in low installation efficiency; secondly, bolt connections require precise hole alignment. Once the hole position deviation is large, it may cause installation difficulties. If a rigid connection is used when there is a deviation, it is easy to cause thread damage, resulting in a loose connection and certain safety hazards; thirdly, prefabricated buildings will vibrate during construction, and bolt connections will loosen if subjected to vibration for a long time, resulting in connection failure, thereby affecting the stability of the building structure; fourthly, for maintenance, renovation or demolition of buildings, it is necessary to loosen the bolts one by one, which increases the workload and time of demolition or renovation. Summary of the invention

[0005] The purpose of the present invention is to overcome the shortcomings of the prior art, solve the problems mentioned in the background technology, and provide a prefabricated building connection component.

[0006] The objective of the present invention is achieved through the following technical solutions: an assembled building connection component, comprising a connection piece and a connection mechanism and a fixing mechanism for installing the connection piece, the connection mechanism comprising a connection column, a support block being fixedly provided at one end of the connection column, a plurality of receiving grooves being provided on the outer surface of the connection column away from the support block, a plurality of receiving grooves being fixedly provided inside each of the plurality of receiving grooves, the fixing mechanism comprising a fixing cylinder, a slot matching the snap-in assembly being provided inside the fixing cylinder, when the connection column is inserted into the fixing cylinder, the snap-in assembly is tilted inside the receiving groove due to the extrusion force, when the snap-in assembly corresponds to the slot, the snap-in assembly automatically changes to a horizontal state and is snap-fitted with the slot, thereby completing a firm connection between the connection column and the fixing cylinder, a control assembly for controlling the tilting of the plurality of snap-in assemblies inside the receiving groove is provided at the center of the connection column, thereby facilitating rapid separation of the connection column and the fixing cylinder.

[0007] Furthermore, the clamping assembly includes a spring sheet fixedly connected to the receiving slot, and a clamping block is fixedly provided at one end of the spring sheet away from the end fixedly connected to the receiving slot.

[0008] Furthermore, one end of the connecting column away from the supporting block is formed with a rounded corner, and the corners of the clamping block are formed with a rounded corner.

[0009] Furthermore, the cross-sectional shape of the block is triangular, and the inclined surface of the block faces the rounded end of the connecting column.

[0010] Furthermore, the control assembly includes a movable rod axially slidably arranged inside the connecting column, the movable rod is hinged with a pull rod at the position corresponding to the multiple blocks, the pull rod is hinged with a connecting block at one end away from the movable rod, the connecting block is fixedly connected to the block, and a first movable groove is opened at the position of the connecting column close to the multiple pull rods.

[0011] Furthermore, one end of the movable rod away from the pull rod passes through the support block, and sliding holes are provided at positions of the connecting column and the support block corresponding to the movable rod.

[0012] Furthermore, a pulling piece is fixedly provided on one end of the movable rod close to the support block, and a conical surface is formed on one end of the pulling piece close to the support block.

[0016] The beneficial effects of the present invention are as follows: by setting a connecting mechanism, a fixing mechanism, a snap-on assembly and a control assembly, firstly, the plug-in connection method can significantly improve assembly efficiency, reduce installation time, and reduce labor costs. At the same time, the plug-in connection can provide better seismic performance because it can effectively disperse and absorb the force generated during an earthquake, reducing potential safety risks caused by loose connections. Secondly, the design of the disassembly structure allows the connector to be quickly and conveniently disassembled, which is very beneficial for the maintenance, renovation or demolition of the building. Due to the plug-in and quick-release design, there is no need to use additional tools for installation or disassembly, reducing the construction difficulty and cost.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Additional aspects and advantages of the present invention will be further given in the following description in conjunction with the accompanying drawings, and in part will become apparent from the following description, or may be learned through practice of the present invention.

[0022] Embodiment 1 of an assembled building connection component of the present invention is as follows Figures 1 to 10 As shown, it includes a connecting member 1 and a connecting mechanism 2 and a fixing mechanism 3 for installing the connecting member 1. The connecting member 1 is provided with a plurality of through holes for installation. The connecting mechanism 2 includes a connecting column 201. A support block 202 is fixedly provided at one end of the connecting column 201. A plurality of receiving grooves 2011 are provided on the outer surface of the connecting column 201 away from the support block 202. A clamping assembly 4 is fixedly provided inside the plurality of receiving grooves 2011. The fixing mechanism 3 includes a fixing cylinder 301. A clamping groove 3 adapted to the clamping assembly 4 is provided inside the fixing cylinder 301. 02. When the connecting column 201 is inserted into the fixed tube 301, the snap-in assembly 4 is tilted inside the receiving groove 2011 due to the extrusion force. When the snap-in assembly 4 corresponds to the slot 302, the snap-in assembly 4 automatically changes to a horizontal state and completes the snap-in connection with the slot 302, thereby completing a firm connection between the connecting column 201 and the fixed tube 301. A control assembly 5 for controlling the tilting of multiple snap-in assemblies 4 inside the receiving groove 2011 is provided at the center of the connecting column 201, thereby facilitating the rapid separation of the connecting column 201 and the fixed tube 301.

[0023] like Figures 1 to 9As shown, the clamping assembly 4 includes a spring piece 401 fixedly connected to the receiving groove 2011, and a clamping block 402 is fixedly provided at one end of the spring piece 401 away from the receiving groove 2011. The end of the connecting column 201 away from the supporting block 202 is formed with a rounded corner. The rounded corner set at the end of the connecting column 201 can facilitate the quick docking of the connecting column 201 and the fixed cylinder 301. The corners of the clamping block 402 are formed with rounded corners. The rounded corners of the clamping block 402 can improve the stability of the connecting column 201 and the fixed cylinder 301 when the connecting column 201 is docked with the fixed cylinder 301. The cross-sectional shape of the clamping block 402 is triangular, and the inclined surface of the clamping block 402 faces the rounded end of the connecting column 201. During installation, the connecting column 201 is connected to the fixed cylinder 301 by passing the through hole of the connector 1. When the clamping block 402 is subjected to the extrusion force , the inclined surface of the block 402 is used to make the block 402 cause the spring piece 401 to tilt inside the receiving groove 2011. When the spring piece 401 tilts inside the receiving groove 2011, the block 402 will be completely accommodated in the receiving groove 2011. At this time, the connecting column 201 can continue to be pushed. When the block 402 corresponds to the slot 302, the elastic force of the spring piece 401 is used to make the block 402 enter the slot 302, thereby completing the firm connection between the connecting column 201 and the fixing cylinder 301. At the same time, with the multiple through holes on the connecting member 1, multiple quick-release structures can be installed, so that several blocks 402 cooperate with the slot 302 at the same time, which can share the tension of the wall, and the lateral tension can be borne by the connecting column 201. At the same time, the block 402 is more reliable than the threaded fit between the bolt and the nut in the prior art, which effectively improves the reliability of the device.

[0024] like Figures 6 to 10As shown, the control assembly 5 includes a movable rod 501 axially slidably arranged inside the connecting column 201, and the movable rod 501 is hinged with a pull rod 502 at a position corresponding to the multiple clamping blocks 402, and the end of the pull rod 502 away from the movable rod 501 is hinged with a connecting block 503, and the connecting block 503 is fixedly connected to the clamping block 402. The connecting column 201 is provided with a first movable groove 2012 at a position close to the multiple pull rods 502, and the ends of the movable rod 501 corresponding to the multiple pull rods 502 are provided with a first hinge. The ends of the plurality of pull rods 502 are hinged to the first hinge groove 5012 through a rotating shaft, and the connecting block 503 is provided with a second hinge groove 5031 at the end corresponding to the pull rod 502. The end of the pull rod 502 is hinged to the second hinge groove 5031 through a rotating shaft. The above structure is used to introduce how the pull rod 502 is hinged to the movable rod 501 and the connecting block 503. The end of the movable rod 501 away from the pull rod 502 passes through the support block 202. The connecting column 201 and the support block 202 correspond to each other. The movable rod 501 is provided with a sliding hole 2013 at the position thereof. The sliding hole 2013 can be used to improve the stability of the movable rod 501 when sliding. A pulling piece 5011 is fixedly provided at one end of the movable rod 501 close to the support block 202. A conical surface is formed at one end of the pulling piece 5011 close to the support block 202. The conical surface can facilitate pulling the movable rod 501. The connecting column 201 is provided with a second movable groove 2014 at the positions corresponding to the plurality of connecting blocks 503. The cooperation between the connecting block 503 and the second movable groove 2014 can ensure the stability of the spring piece 401 when tilting. When the building needs to be maintained, renovated or demolished, the movable rod 501 is pulled by the pulling piece 5011. Then, the cooperation between the pulling rod 502 and the connecting block 503 causes the clamping block 402 to cause the spring piece 401 to tilt inside the accommodating groove 2011. At this time, the clamping block 402 will be separated from the clamping groove 302, and then the connecting column 201 and the fixing cylinder 301 can be quickly disassembled.

[0025] A second embodiment of an assembled building connection component of the present invention is as follows Figure 3 and Fig.11 As shown, a conical ring is formed at the end of the fixing tube 301. When the wall is prefabricated, the fixing tube 301 can be embedded in the prefabricated wall, so that the connection effect with the wall of the fixing tube 301 can be improved through the conical ring, so that after the connecting column 201 is connected with the fixing tube 301, the firmness of the connecting piece 1 after installation can be improved.

[0026] The working process is as follows: S1, such as Figure 1 , Figure 2 and Fig.11 As shown, during production, the fixing tube 301 is pre-buried inside the prefabricated wall, and then the connecting member 1 is butt-jointed with the prefabricated wall for installation; S2, such as Figures 2 to 6As shown, during installation, the connecting column 201 is passed through the through hole of the connecting member 1 and docked with the fixing cylinder 301. When the clamping block 402 is subjected to the extrusion force, the clamping block 402 uses the inclined surface to make the clamping block 402 push the spring piece 401 to tilt inside the receiving groove 2011; S3, such as Figures 2 to 6 As shown, when the spring piece 401 is tilted inside the receiving groove 2011, the block 402 will be completely received inside the receiving groove 2011, and the connecting column 201 can continue to be pushed at this time; S4, such as Figures 7 to 9 As shown, when the block 402 corresponds to the slot 302, the block 402 enters the slot 302 by utilizing the elastic force of the spring sheet 401, thereby completing the firm connection between the connecting column 201 and the fixing cylinder 301; S5. In summary: First, the plug-in connection method can significantly improve assembly efficiency, reduce installation time, and reduce labor costs; second, due to the precise matching of the card block 402 and the card slot 302, the error in the installation process is greatly reduced, and the overall accuracy and stability of the building are improved; third, the automatic pop-up mechanism of the card block 402 ensures the firmness of the connector 1, and the plug-in connection can provide better earthquake resistance because it can effectively disperse and absorb the force generated during an earthquake, reducing the potential safety risks caused by a loose connection; S6, such as Figures 6 to 10 As shown, when the building needs maintenance, renovation or demolition, the movable rod 501 is pulled by the pulling member 5011, and then the pull rod 502 cooperates with the connecting block 503, so that the clamping block 402 causes the spring piece 401 to tilt inside the receiving groove 2011, and then the clamping block 402 is separated from the clamping groove 302, and then the connecting column 201 and the fixing tube 301 can be quickly separated; S7. In summary: the design of the quick-release structure allows the connector 1 to be quickly and conveniently disassembled, which is very beneficial for the maintenance, renovation or demolition of the building. Due to the plug-in and quick-release design, no additional tools are required for installation or disassembly, reducing the construction difficulty and cost.

[0027] 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 principle of the present invention should be included in the protection scope of the present invention.
