Description

Technical Field

[0001] This invention relates to an environmentally friendly prefabricated assembly component. Background Technology

[0002] Precast components refer to steel, wood, or concrete components prefabricated in a factory or on-site according to design specifications. Precast concrete components (PC components) are the foundation for the prefabrication of the main structure, such as precast foundations. There are various types of molds for precast components, including concrete component molds, component molds, hexagonal reservoir slope protection molds, bridge cover plate molds, urban road curbstone molds, cement component molds, cement product component molds, concrete product molds, canal cover plate molds, hollow hexagonal slope protection brick molds, road and bridge cover plate molds, cable trough cover plate molds, roadbed cover plate molds, power cover plate molds, water conservancy irrigation molds, plastic manhole cover molds, water conservancy cover plate molds, ditch cover plate molds, tunnel cover plate molds, and trench cover plate molds. Precast concrete structural components are produced in factories, ensuring the quality of the produced components. On-site assembly is efficient and can significantly shorten the construction period. Currently, precast component connections are made using a method of partially casting with pre-reinforced steel bars, thus splicing and assembling the precast components together. This connection method is complex, inefficient, and results in high overall costs. Summary of the Invention

[0003] The purpose of this invention is to provide an environmentally friendly prefabricated component with a reasonable structure that effectively improves the ease of connection between two prefabricated components, thereby improving assembly efficiency and construction efficiency.

[0004] To achieve the above objectives, the technical solution of the present invention is to design an environmentally friendly prefabricated assembly, including a first prefabricated assembly body and a second prefabricated assembly body, and a connecting component for connecting the first prefabricated assembly body and the second prefabricated assembly body.

[0005] The first prefabricated component body has a first mating surface, and the first mating surface is provided with pre-embedded holes;

[0006] The second precast component body has a second mating surface that fits into the first mating surface, and the second mating surface is provided with a sliding hole corresponding to the pre-embedded hole. The side of the second precast component body facing away from the first precast component body is provided with a receiving hole that is connected to the sliding hole, and a limiting step surface is formed between the receiving hole and the sliding hole.

[0007] The connecting assembly includes a bolt and a threaded sleeve. The threaded sleeve is fixed in a pre-embedded hole and has an internal thread. The bolt includes a screw and a rotating head. The rotating head abuts against a limiting step surface. The screw passes through a sliding hole and is threadedly connected to the internal thread of the threaded sleeve.

[0008] Preferably, the second mating surface is provided with two positioning protrusions, which are located on both sides of the sliding hole, and the first mating surface is provided with two positioning holes that correspond one-to-one with the positioning protrusions.

[0009] Preferably, the connecting assembly further includes a sliding plate slidably connected in the sliding hole. The sliding plate is movably fitted onto the screw. The outer circumferential surface of the screw has two protruding rings. The sliding plate is located between the two protruding rings. Two insertion rods are provided on the side of the sliding plate facing the first mating surface. The two insertion rods are located on both sides of the screw. Each insertion rod has a locking block at the end away from the sliding plate, and the locking block has a pushing inclined surface. The first mating surface has a insertion hole for inserting the insertion rod. The inner circumferential surface of the insertion hole has a spring mounting hole. A stop block is connected to the spring mounting hole by a spring. One end of the stop block extends into the insertion hole, and the end of the stop block has a pushing inclined surface for cooperating with the pushing inclined surface.

[0010] Preferably, the sliding hole is a square hole, and the sliding plate is a square plate.

[0011] Preferably, the bolt is a reinforced stainless steel bolt.

[0012] Preferably, the outer side of both the first precast component body and the outer side of the second precast component body are covered with a thermal insulation layer.

[0013] The advantages and beneficial effects of this invention are as follows: It provides an environmentally friendly prefabricated component with a reasonable structure, which effectively improves the connection convenience between two prefabricated components, thereby helping to improve assembly efficiency and construction efficiency.

[0014] Furthermore, by setting up sliding plates, insert rods, locking blocks, and stops, when the bolts are tightened to the correct position, the stops can restrict the locking blocks connected to the bolts from retracting, thereby preventing the bolts from loosening. This makes the connection between the two precast components more stable and secure, which is beneficial to improving safety in use.

[0015] In addition, by setting up an insulation layer, the thermal insulation performance of precast components can be improved, thereby achieving energy-saving and environmental protection effects. Attached Figure Description

[0017] Figure 2 yes Figure 1 Enlarged view of point A in the middle. Detailed Implementation

[0018] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solutions of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0019] The specific technical solution of this invention is as follows:

[0020] like Figure 1 and Figure 2 As shown, an environmentally friendly prefabricated assembly includes a first prefabricated assembly body 1 and a second prefabricated assembly body 2, as well as a connecting component for connecting the first prefabricated assembly body 1 and the second prefabricated assembly body 2.

[0021] The first prefabricated component body 1 has a first mating surface 3, on which a pre-embedded hole 4 is provided;

[0022] The second precast component body 2 has a second mating surface 5, which is in contact with the first mating surface 3, and the second mating surface 5 is provided with a sliding hole 6 corresponding to the pre-embedded hole 4. The side of the second precast component body 2 facing away from the first precast component body 1 is provided with a receiving hole 7, which is connected to the sliding hole 6, and a limiting step surface 8 is formed between the receiving hole 7 and the sliding hole 6.

[0023] The connecting assembly includes a bolt and a threaded sleeve 9. The threaded sleeve 9 is fixed in the pre-embedded hole 4 and has an internal thread. The bolt includes a screw 10 and a rotating head 11. The rotating head 11 abuts against the limiting step surface 8. The screw 10 passes through the sliding hole 6 and is threadedly connected to the internal thread of the threaded sleeve 9. By adopting the above scheme, when assembling the first prefabricated component body 1 and the second prefabricated component body 2, the second mating surface 5 of the second prefabricated component body 2 is first brought into contact with the first mating surface 3 of the first prefabricated component body 1. Then, the screw 10 of the bolt passes through the sliding hole 6 and is threadedly connected to the internal thread of the threaded sleeve 9. The bolt is tightened until the rotating head 11 abuts against the limiting step surface 8, thereby realizing the connection between the first prefabricated component body 1 and the second prefabricated component body 2 and completing the assembly operation of the prefabricated component.

[0024] Furthermore, the second mating surface 5 is provided with two positioning protrusions 12, which are located on both sides of the sliding hole 6, and the first mating surface 3 is provided with two positioning holes 13 corresponding to the positioning protrusions 12. By adopting the above solution, the pre-positioning of the first prefabricated component body 1 and the second prefabricated component body 2 during connection can be achieved.

[0025] Furthermore, the connecting assembly also includes a sliding plate 14 slidably connected in the sliding hole 6. The sliding plate 14 is movably fitted onto the screw 10. The outer circumferential surface of the screw 10 is provided with two protruding rings 15. The sliding plate 14 is located between the two protruding rings 15. The side of the sliding plate 14 facing the first mating surface 3 is provided with two insertion rods 16. The two insertion rods 16 are respectively located on both sides of the screw 10. The end of each insertion rod 16 away from the sliding plate 14 is provided with a locking block 17, and the locking block 17 is provided with a pushing inclined surface 18. The first mating surface 3 is provided with a insertion hole 19 for the insertion rod 16 to be inserted. The inner circumferential surface of the insertion hole 19 is provided with a spring mounting hole 20. A stop block 22 is connected to the spring mounting hole 20 through a spring 21. One end of the stop block 22 extends into the insertion hole 19, and the end of the stop block 22 is provided with a pushing inclined surface 23 for cooperating with the pushing inclined surface 18. By adopting the above scheme, when the second mating surface 5 and the first mating surface 3 are fully engaged, the locking block 17 will extend into the insertion hole 19. Then, the rotating head 11 will be turned to drive the screw 10 to rotate, so that the screw 10 will gradually be screwed into the threaded sleeve 9 and threadedly connected to the internal thread of the threaded sleeve 9. During this process, the screw 10 will drive the sliding plate 14 to move towards the first precast component body 1 through the two protruding rings 15. Since the sliding plate 14 is movably fitted on the screw 10, the sliding plate 14 will not rotate with the screw 10, and when the sliding plate 14 moves, it will drive the insertion rod 16 and the locking block 17. The block 17 moves within the socket 19, and after it moves to a certain position, the pushing ramp 18 on it will contact the supporting ramp 23. Through the contact and cooperation between the pushing ramp 18 and the supporting ramp 23, the stop block 22 is pushed into the spring mounting hole 20 and the spring 21 is compressed. When the rotating head 11 touches the limiting step surface 8, the block 17 just passes the stop block 22. At this time, the stop block 22 will pop out of the spring mounting hole 20 under the elastic restoring force of the spring 21 and block the rear side of the block 17, so that the block 17 cannot move backward, thereby preventing the bolt from loosening.

[0026] Furthermore, the sliding hole 6 is a square hole, and the sliding plate 14 is a square plate. By adopting the above solution, it is possible to prevent the sliding plate 14 from rotating during movement.

[0027] Furthermore, the bolt is a reinforced stainless steel bolt.

[0028] Furthermore, both the outer side of the first precast component body 1 and the outer side of the second precast component body 2 are covered with an insulation layer 24. By adopting the above solution, the insulation performance of the precast components can be improved, thereby achieving the effect of energy saving and environmental protection.

[0029] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
