Technical Field

[0001] The invention relates to the technical field of construction engineering, and in particular to a single-side formwork structure for a basement beside a foundation pit and a construction method thereof. Background Art

[0002] Traditional basement structure formwork methods mostly use double-sided formwork. Although this method can ensure the stability of the structure to a certain extent, it has a long construction period, consumes a lot of formwork materials, is costly, and is not suitable for complex construction environments adjacent to foundation pits.

[0003] Compared with traditional double-sided formwork, single-sided formwork technology has the advantages of short construction period, less formwork material consumption, and lower cost. Especially in the construction of basement structures next to foundation pits, single-sided formwork technology can significantly reduce the construction space occupied and improve construction efficiency. However, in terms of structural stability, the existing single-sided formwork technology has relatively few support points and complex force, which can easily lead to problems such as formwork deformation and displacement, affecting construction quality. In addition, the existing single-sided formwork technology also has problems such as complex operation and low efficiency during installation and disassembly, which makes it difficult to meet the requirements of modern construction for efficiency, environmental protection, and safety.

The side form 3 is used to form the external shape of the basement wall and is fixedly connected to the inner wall of the basement body 1 by the mounting column 4. The combined use of the connecting sleeve 5, the water-stop screw 6 and the assembly plate 7 can effectively connect the side form 3 with the basement body 1. At the same time, the water-stop screw 6 can also play a waterproof role to prevent groundwater from seeping into the basement. The back of the assembly plate 7 overlaps the surface of the connecting sleeve 5 and is fixed by the water-stop screw 6 to ensure a tight connection between the side form 3 and the basement body 1.

[0062] The cross bar 8, the diagonal brace 9 and the support rod 10 constitute a stable support system. The cross bar 8 is connected to the bottom of the assembly plate 7, and the diagonal brace 9 is connected to the top of the cross bar 8 to form an oblique support, which increases the overall stability. The two support rods 10 are respectively connected to the surface of the assembly plate 7 and the cross bar 8, which further enhances the support effect and can effectively ensure the stability and waterproofness of the single-sided formwork of the basement main body 1, thereby achieving the effect of improving construction quality and safety.

The pedals 12 are fixedly connected to the surface of the inclined rods 9, providing a safe walking and standing platform for construction workers, which is convenient for high-altitude operations. The setting of the standing bracket 13 further ensures a safe working environment for construction workers at the top of the inclined rods 9.

The position of the sleeve frame 16 on the mounting rod 15 can be adjusted through the threaded connection of the baffle 17, which increases the flexibility of use. The rotational connection between the sleeve rod 18 and the threaded collar 19 enables the screw rod 20 to be raised and lowered along the inner wall of the sleeve rod 18. The height adjustment of the screw rod 20 can be easily achieved by rotating the threaded collar 19. The positioning plate 21 at the top of the screw rod 20 cooperates with the fixing bolt 22 to firmly fix the assembly plate 7, thereby enhancing the stability and rigidity of the entire single-sided formwork structure, which not only improves the installation efficiency and construction safety of the single-sided formwork, but also ensures the overall stability and reliability, effectively prevents deformation and displacement during construction, and achieves the dual effects of improving construction quality and safety.

[0095] Example 6

[0096] Reference Figure 1 to Figure 7 , which is the sixth embodiment of the present invention, and this embodiment is different from the fifth embodiment in that: building a large commercial complex;

[0097] Among them, the large-scale commercial complex contains a deep basement structure. Since the basement is close to the foundation pit and the construction environment is complex, it is necessary to ensure the stability of the basement structure and the construction efficiency. In order to meet these requirements, it was decided to adopt a single-sided formwork structure and construction method for the basement next to the foundation pit.

[0098] Basement structure construction:

[0099] Inside the basement body 1 , the supporting piles 2 are first fixedly connected, and these supporting piles 2 play the role of supporting and stabilizing the basement body 1 .

[0100] Next, the side formwork 3 is fixedly connected inside the basement body 1 , and the bottom of the side formwork 3 is plugged into the inner wall of the basement body 1 through the mounting column 4 to ensure the stability of the side formwork 3 .

Two ends of the diagonal tie rod 9 are fixedly connected to two support rods 10, and the top ends of the two support rods 10 are respectively fixedly connected to the surface of the assembly plate 7 and the cross bar 8, forming a triangular stable structure.

[0104] In order to further enhance the stability of the single-sided formwork, a lap bracket 14 is fixedly connected to the top of the cross bar 8, and a mounting rod 15 is fixedly connected to the lap bracket 14. The mounting rod 15 is sleeved with a sleeve frame 16, and one side of the sleeve frame 16 is fixedly connected to a sleeve rod 18, and the top of the sleeve rod 18 is rotatably connected to a threaded collar 19.

At the same time, through precise formwork installation and reinforcement measures, the uniformity and density of concrete construction can be ensured, and the waterproof performance and durability of the basement body 1 can be further improved. In addition, this method can also reduce construction costs and improve the economic and social benefits of the project.

The bottom of the side formwork 3 is inserted into the inner wall of the basement main body 1 through the mounting column 4 to ensure the accurate position and stability of the side formwork 3.

[0111] Then, multiple groups of connecting sleeves 5 are fixedly connected to the surface of the side form 3, and the inner wall of the connecting sleeve 5 is threadedly connected to the water-stop screw 6. The function of the water-stop screw 6 is to prevent water leakage when pouring concrete, and at the same time enhance the connection strength between the side form 3 and the basement main body 1. The surface of the water-stop screw 6 is threadedly connected to the assembly plate 7, and the back side of the assembly plate 7 overlaps the surface of the connecting sleeve 5, further fixing the position of the water-stop screw 6 and the side form 3.
