[0052] 100. Precast components. Detailed Implementation

[0053] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0054] Example 1

[0055] This embodiment provides a connecting lock with a steering pad, such as Figure 1 and Figure 2As shown, it includes: a sub-component 11 and a mother component 12. Both the sub-component 11 and the mother component 12 are provided with anchoring structures 13 for anchoring with the precast component 100. The sub-component 11 includes: a first force transmission box 111 and a first fastener 112. The first fastener 112 is movably disposed within the first force transmission box 111. The mother component 12 includes: a second force transmission box 121, a second fastener 122, and a transmission structure 123. The second fastener 122 is movably disposed within the second force transmission box 121. The transmission structure 123 is in transmission engagement with the second fastener 122. The transmission structure drives the second fastener 122 to rotate and connects with the first fastener 112.

[0056] Specifically, the transmission structure 123 is a turbine screw. An opening is provided on the second force transmission box 121 for the turbine screw to pass through. A gear that mates with the turbine screw is provided on the surface of the second fastener 122. When force is applied to the turbine screw, the direction of the force is changed and transmitted to the second fastener 122. The anchoring structure 13 is an anchoring bar or protrusion. By welding the anchoring bar or protrusion to the reinforcing steel of the precast component 100, the bonding strength and integrity between the sub-component 11 and the corresponding precast component 100, and between the parent component 12 and the corresponding precast component 100, can be ensured.

[0057] Before assembly, the sub-component 11 and the mother component 12 are pre-embedded in the corresponding precast components 100. The sub-component 11 and the mother component 12 are anchored to the precast components 100 through the anchoring structure 13. Then, the first fastener 112 and the second fastener 122 are assembled together. The transmission structure 123 drives the second fastener 122 to rotate, thereby connecting the first fastener 112 and the second fastener 122. Since the second fastener 122 is located inside the second force transmission box 121, it can move and rotate freely within the second force transmission box 121. Furthermore, the first fastener 112 can move and rotate within the first force transmission box 111, allowing the sub-component 11 and the mother component 12 to have a certain initial installation error in any direction. This assembly method can be completed directly on the sub-component 11 (or its corresponding prefabricated component) and the mother component 12 (or its corresponding prefabricated component), avoiding the need for assembly operations between the two components. There is no need to reserve operating space at the docking position, which can meet the assembly requirements of seamless connection of prefabricated components. Moreover, the operation of connecting prefabricated components is quick and convenient, and the construction efficiency is higher.

[0058] Furthermore, the second force transmission box 121 is provided with a cavity for mounting the second fastener 122. Several elastic elements 124 are provided on the inner side wall of the second force transmission box 121. The elastic elements 124 are connected to the second fastener 122. Based on this, the second fastener 122 can be movably mounted in the second force transmission box 121. During construction, the angle and position of the second fastener 122 can be flexibly adjusted.

[0059] Preferably, the first fastener 112 is a screw and the second fastener 122 is a nut.

[0060] For example, the elastic element 124 can be implemented by a spring. Springs are provided on the end face and side face of the nut. The two ends of the springs are respectively connected to the nut and the inner side wall of the second force transmission box 121, so that the nut is floating in the second force transmission box 121 and its position and direction can be adjusted in the second force transmission box 121.

[0061] The first force transmission box 111 is provided with a cavity for setting the screw and a first opening 1111 for the screw to pass through. The head of the screw is located in the cavity, and the threaded part of the screw extends to the outside of the first force transmission box 111. Alternatively, the screw can be located in the cavity and the threaded part of the screw can be pulled out to the outside of the first force transmission box 111 during use. A limit spring 115 is connected between the screw and the inner wall of the first force transmission box 121. The size of the first force transmission box 111 can be flexibly adjusted according to the size of the screw, and the length of the threaded part of the screw can also be adjusted according to the actual situation.

[0062] In this embodiment, a first gasket group 113 and a second gasket group 114 are provided on the inner sidewall of the screw and the first force transmission box 111. The first gasket group 113 and the second gasket group 114 are perpendicular to each other. Both the first gasket group 113 and the second gasket group 114 are cylindrical gaskets. The mutually perpendicular cylindrical gaskets provide the screw with rotation in any direction and force transmission in any direction, so that the screw axis has the function of deflection in any direction.

[0063] To further improve construction efficiency, the second force transmission box 121 is provided with a second opening 1211 for the screw to pass through, and the second opening 1211 corresponds to the position of the threaded hole of the nut; a guide member 125 is provided between the second opening 1211 and the nut, so that the screw and the threaded hole of the nut can be aligned during construction.

[0064] The specific implementation process of this embodiment will be explained in further detail below:

[0065] When the connecting lock is processed in the prefabricated component 100, it can be pre-embedded in the prefabricated component 100. When connecting two prefabricated components 100, first align the screw with the nut, and use a wrench to turn the worm screw so that the nut rotates. During this period, the screw can have an initial deviation in various directions. During the connection process of the nut rotating and tightening, one end of the screw head is adjusted in direction by the first washer group 113 and the second washer group 114, and one end of the screw thread is adjusted in direction by the movement of the floating nut. Finally, the connection between the screw and the nut is realized, and the effective force transmission between the first force transmission box 111 and the second force transmission box 121 is realized. At this time, the screw only bears the axial tensile force, and the nut and the force transmission box transmit force through end face bearing pressure.

[0066] Example 2

[0067] This embodiment provides a connecting lock with a steering pad, such as Figure 3 As shown, the difference between it and Embodiment 1 is that the screw is a spherical screw, and the inner sidewall of the first force transmission box 111 that abuts against the spherical screw is set as an arc-shaped inner sidewall that cooperates with the spherical screw.

[0068] Based on the above settings, the use of a gasket set can be eliminated. The screw and the first force transmission box 111 are in spherical contact, which can provide the screw to rotate in any direction and transmit force in any direction, so that the screw axis has the ability to deflect in any direction. For the specific implementation of this embodiment, please refer to Embodiment 1, which will not be repeated here.

[0069] Example 3

[0070] This embodiment provides a connecting lock with a steering pad, such as Figure 4 and Figure 5 As shown, it includes: a sub-component 21 and a mother component 22. Both the sub-component 21 and the mother component 22 are provided with anchoring structures 23 for anchoring with precast components. The sub-component 21 includes: a first force transmission box 211 and a first fastener 212, the first fastener 212 being movably disposed within the first force transmission box 211. The mother component 22 includes: a second force transmission box 221, a second fastener 222 and a transmission structure 223, the second fastener 222 being movably disposed within the second force transmission box 221, and the transmission structure 223 engaging with the second fastener 222 in a transmission cooperation. The transmission structure drives the second fastener 222 to rotate and connects with the first fastener 212.

[0071] Specifically, the transmission structure 223 is a turbine screw. An opening is provided on the second force transmission box 221 for the turbine screw to pass through. A gear that meshes with the turbine screw is provided on the surface of the second fastener 222. When force is applied to the turbine screw, the direction of the force is changed and transmitted to the second fastener 222. The anchoring structure 23 is an anchoring bar or protrusion. By welding the anchoring bar or protrusion to the reinforcing steel of the precast component, the bonding strength and integrity between the sub-component 21 and the corresponding precast component, and between the parent component 22 and the corresponding precast component, can also be guaranteed.

[0072] Before assembly, the sub-component 21 and the mother component 22 are pre-embedded in the corresponding precast components. The sub-component 21 and the mother component 22 are anchored to the precast components through the anchoring structure. Then, the first fastener 212 and the second fastener 222 are assembled together. The transmission structure 223 drives the second fastener 222 to rotate, thereby connecting the first fastener 212 and the second fastener 222. Since the second fastener 222 is located in the second force transmission box 221 and can move and rotate arbitrarily within the second force transmission box 221, and the first fastener 212 can move and rotate within the first force transmission box 211, the sub-component 21 and the mother component 22 are allowed to have a certain initial installation error in any direction. This assembly method can be completed directly on the sub-component 21 (or its corresponding precast component) and the mother component 22 (or its corresponding precast component), avoiding the need for assembly operations between the two components. There is no need to reserve operating space at the docking position. This can meet the assembly requirements for seamless connection of precast components. Moreover, the operation of connecting precast components is quick and convenient, and the construction efficiency is higher.

[0073] Furthermore, the second force transmission box 221 is provided with a cavity for mounting the second fastener 222. Several elastic elements 224 are provided on the inner side wall of the second force transmission box 221. The elastic elements 224 are connected to the second fastener 222. Based on this, the second fastener 222 can be movably mounted in the second force transmission box 221. During construction, the angle and position of the second fastener 222 can be flexibly adjusted.

[0074] Preferably, the first fastener 212 is a nut and the second fastener 222 is a screw.

[0075] For example, the elastic element 224 can be implemented as a spring. A spring is provided at the top of the screw, and the two ends of the spring are respectively connected to the top of the screw and the inner side wall of the second force transmission box 221, so that the screw is floating in the second force transmission box 221 and its position and direction can be adjusted within the second force transmission box 221.

[0076] The second force transmission box 221 is provided with a cavity for setting the screw and a third opening 2211 for the screw to pass through. The side and end face of the nut are connected to the inner wall of the first force transmission box 211 by a number of limiting springs 214.

[0077] In this embodiment, a third washer group 225 and a fourth washer group 226 are provided on the inner sidewall of the screw and the second force transmission box 221. The third washer group 225 and the fourth washer group 226 are perpendicular to each other. Both the third washer group 225 and the fourth washer group 226 are cylindrical washers. The mutually perpendicular cylindrical washers provide the screw with rotation and force transmission in any direction, so that the screw axis has the function of deflection in any direction.

[0078] To further improve construction efficiency, the first force transmission box 211 is provided with a fourth opening 2111 for the screw to pass through, and the fourth opening 2111 corresponds to the threaded hole of the nut; a guide member 215 is provided between the fourth opening 2111 and the nut. During construction, it is convenient to align the threaded holes of the screw and the nut.

[0080] Example 4

[0081] This embodiment provides a connecting lock with a steering pad, such as... Figure 6 As shown, the difference between it and embodiment 3 is that the screw is a spherical screw, and the inner sidewall of the second force transmission box 221 that abuts against the spherical screw is set as an arc-shaped inner sidewall that cooperates with the spherical screw.

[0082] Based on the above settings, the use of gaskets can be eliminated. The screw and the second force transmission box 221 adopt spherical contact, which can provide the screw to rotate in any direction and transmit force in any direction, so that the screw axis has the ability to deflect in any direction. For the specific implementation of this embodiment, please refer to Embodiment 1 or Embodiment 3, which will not be described in detail here.
