Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated buildings, and particularly to a connecting member for prefabricated buildings. Background Art

[0002] Connecting members for prefabricated buildings 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 existing common connection method is to connect prefabricated components through bolts and nuts.

[0003] In a holistic connection system for a reinforced concrete prefabricated building disclosed in Chinese Patent Publication No. CN110130502B, the holistic connection system of the reinforced concrete prefabricated building connects the embedded plate of the beam and the embedded plate of the upper column through bolts and nuts, and then hoists the floor slab and the floor slab at the beam-column joint 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 each bolt one by one and corresponding tools such as wrenches or electric screwdrivers, resulting in low installation efficiency; secondly, bolt connections require precise hole alignment. Once the hole positions deviate greatly, it may lead to difficult installation. If forced connection is carried out during deviation, it is easy to cause thread damage, resulting in insecure connection and certain safety hazards; thirdly, prefabricated buildings vibrate during construction. Bolt connections will become loose under long-term vibration, leading to connection failure and affecting the stability of the building structure; fourthly, for building maintenance, renovation or demolition, bolts need to be loosened 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 existing technologies, solve the problems mentioned in the background art, and provide a connecting member for prefabricated buildings.

[0006] The purpose of the present invention is achieved through the following technical solutions: A connecting member for prefabricated buildings includes a connecting piece, a connecting mechanism and a fixing mechanism for installing the connecting piece. The connecting mechanism includes a connecting column. One end of the connecting column is fixedly provided with a supporting block. A plurality of receiving grooves are formed on the outer surface of the connecting column away from the supporting block. A clamping component is fixedly provided inside each of the plurality of receiving grooves. The fixing mechanism includes a fixing cylinder. A clamping groove adapted to the clamping component is formed inside the fixing cylinder. When the connecting column is inserted into the fixing cylinder, the clamping component inclines inside the receiving groove due to the extrusion force. When the clamping component corresponds to the clamping groove, the clamping component automatically changes to a horizontal state and completes clamping with the clamping groove, thus completing the firm connection between the connecting column and the fixing cylinder. A control component for controlling the inclination of the plurality of clamping components inside the receiving groove is provided at the center of the connecting column, thus facilitating the quick disassembly of the connecting column and the fixing cylinder.

[0007] Further, the snap - connection component includes a resilient piece fixedly connected to the receiving groove, and a snap block is fixedly provided at one end of the resilient piece away from the fixed connection with the receiving groove.

[0008] Further, a rounded corner is formed at one end of the connecting column away from the support block, and rounded corners are formed at the corners of the snap block.

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

[0010] Further, the control component includes a movable rod axially slidably disposed inside the connecting column. At positions corresponding to multiple snap blocks, a pull rod is hinged to the movable rod. At one end of the pull rod away from the movable rod, a connecting block is hinged, and the connecting block is fixedly connected to the snap block. At positions of the connecting column close to multiple pull rods, a first movable groove is opened.

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

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

[0013] Further, second movable grooves are opened at positions of the connecting column corresponding to multiple connecting blocks.

[0014] Further, first hinge grooves are opened at the ends of the movable rod corresponding to multiple pull rods, and the ends of multiple pull rods are hinged to the first hinge grooves through a rotating shaft.

[0015] Further, second hinge grooves are opened at the ends of the connecting block corresponding to the pull rod, and the ends of the pull rod are hinged to the second hinge grooves through a rotating shaft.

[0016] The beneficial effects of the present invention are as follows: By providing a connection mechanism, a fixing mechanism, a snap - connection component and a control component, firstly, the plug - in connection method can significantly improve the assembly efficiency, reduce the installation time, lower the labor cost. At the same time, the plug - in connection can provide better seismic resistance performance because it can effectively disperse and absorb the forces generated during an earthquake, reducing the potential safety risks caused by insecure connections. Secondly, the detachable structure design enables the connection parts to be quickly and conveniently disassembled, which is very beneficial for the maintenance, renovation or demolition of buildings. And due to the plug - in and quick - disassembly design, no additional tools are required for installation or disassembly, reducing the construction difficulty and cost.

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] Additional aspects and advantages of the present invention will be further given in the following description in conjunction with the accompanying drawings, some of which will become obvious from the following description, or can be understood through the practice of the present invention.

[0032] Embodiment 1 of a prefabricated building connection member of the present invention is as Figures 1 to 10 shown, and includes a connecting member 1, a connecting mechanism 2 for installing the connecting member 1, and a fixing mechanism 3. A plurality of through holes for installation are provided on the connecting member 1. The connecting mechanism 2 includes a connecting column 201. One end of the connecting column 201 is fixedly provided with a support block 202. 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 each of the plurality of receiving grooves 2011. The fixing mechanism 3 includes a fixing cylinder 301. A clamping groove 302 adapted to the clamping assembly 4 is provided inside the fixing cylinder 301. When the connecting column 201 is inserted into the inside of the fixing cylinder 301, the clamping assembly 4 is inclined inside the receiving groove 2011 due to the extrusion force. When the clamping assembly 4 corresponds to the clamping groove 302, the clamping assembly 4 automatically changes to a horizontal state and completes the clamping with the clamping groove 302, thereby completing the firm connection between the connecting column 201 and the fixing cylinder 301. A control assembly 5 for controlling the inclination of the plurality of clamping assemblies 4 inside the receiving groove 2011 is provided at the center of the connecting column 201, thereby facilitating the quick disassembly of the connecting column 201 and the fixing cylinder 301.

[0033] As Figures 1 to 9As shown in the figure, the snap - fit component 4 includes a spring piece 401 fixedly connected to the receiving groove 2011. A snap block 402 is fixedly provided at one end of the spring piece 401 away from the fixed connection with the receiving groove 2011. A fillet is formed at one end of the connecting column 201 away from the support block 202. By using the fillet provided at the end of the connecting column 201, the quick docking of the connecting column 201 and the fixed cylinder 301 can be facilitated. A fillet is formed at the corner of the snap block 402. By using the fillet at the corner of the snap block 402, when the connecting column 201 is docked with the fixed cylinder 301, the snap block 402 can be stably located inside the receiving groove 2011. The cross - sectional shape of the snap block 402 is triangular, and the inclined surface of the snap block 402 faces one end of the fillet of the connecting column 201. During installation, the connecting column 201 is passed through the through - hole of the connecting piece 1 to be docked with the fixed cylinder 301. When the snap block 402 is subjected to a squeezing force, due to the inclined surface of the snap block 402, the snap block 402 causes the spring piece 401 to incline inside the receiving groove 2011. When the spring piece 401 inclines inside the receiving groove 2011, the snap block 402 will be completely received inside the receiving groove 2011. At this time, the connecting column 201 can be further pushed. When the snap block 402 corresponds to the card slot 302, due to the elastic force of the spring piece 401, the snap block 402 enters the card slot 302, thus completing the firm connection between the connecting column 201 and the fixed cylinder 301. At the same time, in cooperation with the multiple through - holes on the connecting piece 1, multiple quick - release structures can be installed, so that several snap blocks 402 cooperate with the card slots 302 at the same time, and the tensile force of the wall can be shared. The transverse tensile force can be borne by the connecting column 201. At the same time, the snap block 402 is more reliable than the thread fit between the bolt and the nut in the prior art, effectively improving the reliability of the device.

[0034] As Figures 6 to 10As shown in the figure, the control component 5 includes a movable rod 501 axially slidably arranged inside the connecting column 201. At positions corresponding to multiple clamping blocks 402, a pull rod 502 is hinged to the movable rod 501. At the end of each pull rod 502 away from the movable rod 501, a connecting block 503 is hinged. The connecting block 503 is fixedly connected to the clamping block 402. At positions of the connecting column 201 close to multiple pull rods 502, a first movable groove 2012 is opened. At the ends of the movable rod 501 corresponding to multiple pull rods 502, a first hinge groove 5012 is opened. The ends of multiple pull rods 502 are hinged to the first hinge groove 5012 through a rotating shaft. At the end of the connecting block 503 corresponding to the pull rod 502, a second hinge groove 5031 is opened. The end of the pull rod 502 is hinged to the second hinge groove 5031 through a rotating shaft. With the above structure, it is introduced 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 penetrates through the support block 202. At positions of the connecting column 201 and the support block 202 corresponding to the movable rod 501, sliding holes 2013 are opened. By using the provided sliding holes 2013, the stability of the movable rod 501 during sliding can be improved. At the end of the movable rod 501 close to the support block 202, a pulling member 5011 is fixedly provided. At the end of the pulling member 5011 close to the support block 202, a conical surface is formed. By using the provided conical surface, it is convenient to pull the movable rod 501. At positions of the connecting column 201 corresponding to multiple connecting blocks 503, second movable grooves 2014 are opened. By using the cooperation between the connecting block 503 and the second movable groove 2014, the stability of the elastic piece 401 when tilted can be ensured. When maintenance, renovation or demolition of a building is required, the movable rod 501 is pulled through the pulling member 5011, and then through the cooperation between the pull rod 502 and the connecting block 503, the clamping block 402 causes the elastic piece 401 to tilt inside the receiving 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 fixed cylinder 301 can be quickly disassembled.

[0035] Embodiment 2 of an assembled building connection member of the present invention is as Figure 3 and Figure 11 shown. At the end of the fixed cylinder 301, a conical ring is formed. During prefabrication of the wall, the fixed cylinder 301 can be embedded inside the prefabricated wall, so that the connection effect between the fixed cylinder 301 and the wall can be improved through the conical ring, and after the connecting column 201 is docked with the fixed cylinder 301, the firmness of the installation of the connection member 1 can be improved.

[0036] The working process is as follows:

[0037] S1. As Figure 1 、 Figure 2 and Figure 11 shown, during production, the fixed cylinder 301 is embedded inside the prefabricated wall, and then the connection member 1 is docked and installed with the prefabricated wall;

[0038] S2, as shown in Figures 2 to 6 When installing, the connecting column 201 is passed through the through hole of the connecting member 1 to be docked with the fixing cylinder 301. When the clamping block 402 is subjected to a squeezing force, the inclined surface of the clamping block 402 is utilized to cause the elastic piece 401 to incline inside the receiving groove 2011;

[0039] S3, as shown in Figures 2 to 6 When the elastic piece 401 inclines inside the receiving groove 2011, the clamping block 402 will be completely received inside the receiving groove 2011. At this time, the connecting column 201 can be continuously pushed;

[0040] S4, as shown in Figures 7 to 9 When the clamping block 402 corresponds to the clamping groove 302, the elastic force of the elastic piece 401 is utilized to cause the clamping block 402 to enter the clamping groove 302, thereby completing the firm connection between the connecting column 201 and the fixing cylinder 301;

[0041] S5. In summary: First, the plug-in connection method can significantly improve the assembly efficiency, reduce the installation time, and lower the labor cost; Second, due to the precise fit between the clamping block 402 and the clamping groove 302, the error during the installation process is greatly reduced, improving the overall accuracy and stability of the building; Third, the automatic ejection mechanism of the clamping block 402 ensures the firmness of the connecting member 1, and at the same time, the plug-in connection can provide better seismic resistance because it can effectively disperse and absorb the forces generated during an earthquake, reducing the potential safety risks caused by loose connections;

[0042] S6, as shown in Figures 6 to 10 When maintenance, renovation, or demolition of the building is required, the movable rod 501 is pulled by the pulling member 5011, and then through the cooperation between the pull rod 502 and the connecting block 503, the clamping block 402 is caused to make the elastic piece 401 incline inside the receiving 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;

[0043] S7. In summary: The design of the quick-disassembly structure enables the connecting member 1 to be quickly and conveniently disassembled, which is very beneficial for the maintenance, renovation, or demolition of the building. And due to the plug-in and quick-disassembly designs, no additional tools are required for installation or disassembly, reducing the construction difficulty and cost.

[0044] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
