[0002] Prefabricated components refer to building components produced in factories, production bases or temporary production sites. These components are assembled and installed at the construction site to form part of the building. Prefabricated components are usually produced on standardized and normalized production lines to ensure product quality and construction efficiency. Connectors are used to connect two steel rods used in buildings.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Reference Figure 1-Figure 3 The utility model provides an embodiment: a connector for butt joint of prefabricated components, including a connector 1, one end of the connector 1 is rotatably connected to a connector 2, the outside of the connector 1 and the connector 2 are fixedly connected to a fixed block 3, the inside of the fixed block 3 is slidably connected to a pull rod 5, the outside of the pull rod 5 is rotatably connected to a connecting rod 6, the other end of the connecting rod 6 is rotatably connected to a limiting block 8, one side of the limiting block 8 is fixedly connected to a spring 10, the other side of the limiting block 8 is fixedly connected to a clamping block 9, limiting grooves 7 are provided on both sides of the inside of the fixed block 3, the other ends of the connector 1 and the connector 2 are slidably connected to a steel rod 4, the inside of the steel rod 4 is provided with clamping grooves 11, and an adjustment component 12 is installed on the outside of the connector 1.

[0023] Specifically, the steel rod 4 can be pre-fixed by the fixing block 3 fixed on the outside of the connecting member 1 and the connecting member 2. First, the pull rod 5 on the outside of the fixing block 3 is pulled, and the connecting rods 6 on both sides are driven to rotate by the pull rod 5, so that the limit block 8 connected to the other end of the connecting rod 6 slides inside the limit groove 7, and then the limit block 8 drives the clamping block 9 to slide toward the inside of the limit groove 7, and at the same time, pressure is applied to the spring 10 to shrink it, and the steel rod 4 is inserted into the inside of the connecting member, and the pull rod 5 is loosened so that the pressure on the spring 10 disappears and begins to reset, thereby pushing the limit block 8 to slide, and finally pushing the clamping block 9 into the clamping groove 11 to complete the plug-in fit, thereby completing the fixation of the steel rod 4. The steel rod 4 is fixed by clamping, so that the work efficiency of the workers is improved, and it is convenient for subsequent adjustments, thereby improving the integrity of the building structure.

[0024] Reference Figure 1The adjustment component 12 includes a screw rod 1203, one end of which is rotatably connected to the outside of the connecting member 1, the other end of the screw rod 1203 is threadedly connected to the sleeve rod 1201, and the other end of the sleeve rod 1201 is internally threadedly connected to the screw rod 1202; the other end of the screw rod 1202 is rotatably connected to the outside of the connecting member 2, and the screw rod 1202 and the screw rod 1203 are symmetrically arranged.

[0025] Specifically, by rotating the sleeve rod 1201 and rotating the other end of the screw rod 1202 to be connected to the outside of the connecting piece 2, and rotating one end of the screw rod 1203 to be connected to the outside of the connecting piece 1, the screw rod 1202 and the screw rod 2 1203 can be moved closer to or farther away from each other, thereby changing the overall length of the adjustment component 12 structure, thereby changing the angle between the connecting piece 1 and the connecting piece 2, so that the prefabricated components can be flexibly adjusted in position and angle during installation to adapt to actual construction conditions and ensure the correct installation of the components.

[0026] Reference Figure 1-Figure 3 A groove 14 is provided at the top of one end of the steel rod 4, and internal threaded holes 15 are provided on both sides of the outside of one end of the steel rod 4; the other end of the spring 10 is fixedly connected to the inner wall of the limiting groove 7, and the outside of the spring 10 and the limiting block 8 are slidably connected to the inside of the limiting groove 7; the longitudinal section of the clamping block 9 is set to be square, and the outside of the clamping block 9 is plug-fitted with the inside of the clamping groove 11; the bottom of the fixed block 3 is slidably connected to the inner wall of the groove 14; the ends of the connecting piece 1 and the connecting piece 2 that are away from each other are both threadedly connected with bolts 13.

[0027] Specifically, the steel rod 4 can be inserted into the interior of the connecting piece by opening the groove 14, and then the steel rod 4 can be fixed by plugging the block 9 into the groove 11, and the internal threaded holes 15 opened on both sides of the outside of one end of the steel rod 4 can be used to rotate the bolt 13 to make it enter the internal threaded hole 15 to fix the steel rod 4, ensuring that the fixing effect is stable and will not loosen. One end of the spring 10 is fixed to the inner wall of the limit groove 7, so that the spring 10 and the limit block 8 will not slide and will ensure the stability of the structure. The longitudinal section of the block 9 is set to a square, so that it can be more firmly engaged with the groove 11.

[0028] Working principle: When using this connecting piece, first pull the pull rod 5 on the connecting piece 1, and drive the connecting rods 6 connected on both sides to move through the pull rod 5, so that the limit block 8 connected to the other end thereof slides inside the limit groove 7, and applies pressure to the spring 10 to make it contract. At the same time, the limit block 8 drives the clamping block 9 to slide toward the inside of the limit groove 7. At this time, the end of the steel rod 4 with the groove 14 is inserted into the inside of the connecting piece 1, and then the pull rod 5 is released. The spring 10 loses pressure and starts to reset, thereby pushing the limit block 8 to move, so that the clamping block 9 slides to the inside of the clamping groove 11 to complete the plug-in fit, thereby realizing the pre-fixation of the steel rod 4 and avoiding dislocation when fixing with the bolt 13. , constant adjustment is required, which reduces work efficiency. Then, by rotating the bolts 13 on both sides of the connecting piece 1, the bolts 13 are inserted into the internal threaded holes 15 to complete the fixation of the steel rod 4. Then, the same operation is repeated to fix the other steel rod 4 through the connecting piece 2, thereby realizing the connection of the two steel rods 4, which can meet the diverse needs of building structures. At the same time, by rotating the sleeve rod 1201, the screw rod 1 1202 and the screw rod 2 1203 can move toward the inside of the sleeve rod 1201, thereby realizing the adjustment of the angle between the two connecting pieces, so that the component can flexibly adjust the position and angle during installation to adapt to the actual construction conditions and ensure the correct installation of the component.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
