TECHNICAL FIELD
[0001] The utility model relates to the technical field of building construction more particularly relates to a kind of reusable pile cap pre-buried corrugated pipe positioning device. BACKGROUND
[0002] In the field of building construction, the positioning of pile cap pre-buried corrugated pipe has always been a key link in the construction process. The traditional positioning method usually adopts a simple rectangular frame structure. Although this structure can meet the construction requirements to some extent, it often encounters many problems when facing large-diameter cylinders, especially cylinders with a diameter exceeding 800mm. For example, the pre-buried corrugated pipe is prone to deformation during the pouring of concrete on the pile cap, which makes it difficult to align with the column reinforcement accurately in the later stage, thereby affecting the stability and construction quality of the entire building structure. In addition, the traditional positioning device is often difficult to reuse after construction, resulting in waste of materials and increased construction costs.
[0003] In order to overcome the above problems, the industry has been exploring more efficient, stable and reusable pile cap pre-buried corrugated pipe positioning devices. Currently, although some improved solutions have been proposed, such as using a multi-layer ring-shaped skeleton structure to enhance stability, separating the ring-shaped skeleton into multiple corrugated pipe positioning openings with separation ribs, and setting internal support ribs on the ring-shaped skeleton to improve overall strength, these solutions still have certain limitations. For example, some devices are difficult to disassemble quickly after construction, cannot be reused efficiently, or are easily damaged during disassembly, affecting their subsequent performance.
[0004] Therefore, how to design a pile cap pre-buried corrugated pipe positioning device that can effectively solve the positioning problem of large-diameter cylinders and be quickly disassembled and reused after construction is a technical problem that needs to be solved in the current field of building construction.
