[0026] Reference Figure 1-3 , a hole reservation method based on BIM technology, comprising the following steps:

[0027] S1. Make a hole embedded part 1. According to the detailed list of reserved holes, make a hole embedded part 1 that meets the inner cavity size of the hole. The hole embedded part 1 is made by pouring concrete on the forming mold shell. A connecting plate 7 is embedded on the outer side of the hole embedded part 1. A steel skeleton 8 is arranged inside the hole embedded part 1. A connecting seat 9 is fixedly connected to the surface of the steel skeleton 8. The steel skeleton 8 is fixedly connected to the inner side of the connecting plate 7 through the connecting seat 9. For details, see Figure 3 .

[0028] S2. Adjust the position of the hole embedded part 1. Place the hole embedded part 1 on the casting platform, and use the pull rod 2 to adjust and fix the position of the hole embedded part 1.

[0029] Among them, the casting platform includes a vibration table 4, multiple side templates 5 and multiple first hydraulic cylinders 6, the side templates 5 are slidably installed on the upper surface of the vibration table 4, the first hydraulic cylinder 6 is fixedly installed on the upper side of the vibration table 4, and the side templates 5 are fixedly connected to the telescopic end of the first hydraulic cylinder 6.

[0030] The side formwork 5 includes a first formwork 10 and a second formwork 11. The two first formworks 10 are arranged in parallel, and the two second formworks 11 are arranged in parallel. Under the action of the first hydraulic cylinder 6, the side formworks 5 are close to each other, that is, the two first formworks 10 and the two second parallel formworks form a casting area on the upper surface of the vibration table 4. The hole embedded part 1 is placed in the casting area. One end of the tie rod 2 is threadedly connected with a sliding block 12, and a sliding groove is arranged on the outer side of the connecting plate 7. The sliding block 12 is slidably installed in the sliding groove. The other end of the tie rod 2 passes through the side formwork 5, and a nut ring 13 is threadedly installed on the end of the tie rod 2.

[0031] A plurality of traction beams 14 are slidably mounted on the upper surface of the vibration table 4, and a plurality of second hydraulic cylinders 15 are fixedly mounted on the upper surface of the vibration table 4. Each traction beam 14 is fixedly connected to the telescopic end of the corresponding second hydraulic cylinder 15. A through insertion hole is provided on the side of the traction beam 14. The end of the pull rod 2 away from the hole embedded part 1 passes through the insertion hole. The end of the pull rod 2 is fixed to the traction beam 14 by using the nut ring 13. The second hydraulic cylinder 15 is used to pull the hole embedded part 1 to an offset position, and the setting parameters of the reserved hole are adjusted to meet the requirements of the parameter change.

[0032] In this embodiment, the position where the hole embedded component 1 is set refers to the distance between the outer surface of the hole embedded component 1 and the first template 10 and the second template 11.

[0033] S3, casting of unit component 3. Before casting of building component, a connecting sleeve 16 is movably installed on the surface of tie rod 2, and steel mesh 17 is laid in the casting area.

The position of the hole embedded part 1 in step S2 is checked to meet the requirements. Concrete is poured on the casting platform. The concrete fills the outside of the hole embedded part 1, and the tie rod 2 and the steel mesh 17 are buried in the poured concrete to form a building component that is condensed into one with the hole embedded part 1. Finally, the position parameters of the hole embedded part 1 are rechecked.

[0034] After the concrete building components are cured, during the demoulding process, the first hydraulic cylinder 6 is used to drive each side formwork 5 to separate from the building components. Figure 1 By setting a prefabricated hole embedded part 1, the unit component 3 and the hole embedded part 1 are cast together to form a structural component with a more complete and solid hole edge, which solves the problem of the existing technology of reserving holes requiring overlapping molds, which is time-consuming and labor-intensive, and there is no need to remove the mold, so the construction efficiency is further improved.

[0035] It should be noted that most of the reserved holes in building components are implemented according to unified standards, and the utilization rate of the same specifications and models is high. The hole embedded parts 1 are cast separately, and a type of hole embedded parts 1 can be produced using one mold. The design of sequential production greatly reduces its volume, makes its size easy to control, and reduces the difficulty of casting and mold making, which brings convenience to the production of improving the quality of building components.

[0036] like Figure 3As shown, the casting platform can also be used to cast and manufacture building components without holes. The present invention sets a casting platform, adopts a method of installing hole embedded parts 1 before casting, and adjusts the position of the hole embedded parts 1 by the pull rod 2 to determine the number and position of the reserved holes, so that the production of building components is simpler, and the reserved hole position parameters can be adjusted in time according to the change requirements to meet the requirements of collision detection through BIM software, simulation of reserved hole position conflict problems, and change of setting parameters in actual production.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
