Description

Technical Field

[0001] The utility model relates to a template for prefabricated high-pile dock panels. Background Art

[0002] In recent years, the number of various types of docks in my country has continued to increase. As the competition in the hydraulic dock construction market becomes increasingly fierce, the requirements for project quality are also getting higher and higher. The proportion of prefabricated components in the project has also greatly increased. Among them, prefabricated panels are a commonly used prefabricated component in water transport projects. The prefabricated panels of the dock are manufactured in factories and can be quickly assembled on site, which greatly improves the assembly rate of the dock and reduces the probability of high risks in offshore operations. It is widely used in dock construction.

[0003] Precast panels, the main structure of high-pile wharves, are flat and simple, but they have a variety of designs and a high number of protruding steel bars. Traditional wharf construction involves multiple steps, including rebar, formwork, and concrete processing. During precast construction, the technical skills of the personnel vary, resulting in low efficiency and unreliable quality due to the lack of compliance with regulatory standards. Against this backdrop, ensuring the overall quality of wharf projects requires comprehensive control of precast components to continuously improve their quality.

[0004] During the production of precast panels, considering the numerous protruding steel bars, traditional construction techniques usually require drilling holes in the formwork surface, installing the integral formwork, and then manually tying the steel bars. After the concrete is poured, a single channel steel is installed on the top surface of the precast panel to press the groove.

[0005] This ordinary steel formwork structure will have the following defects:

[0006] ① On-site construction requires bundled steel bars. If some steel bars with hooks cannot be installed, on-site steel bar installation is inconvenient and construction efficiency is low;

[0007] ② When prefabricated components are installed on the formwork, slight deformation errors will occur. The hole positions are designed to facilitate the insertion of steel bars, which increases the opening range and easily causes a large amount of grout leakage.

[0008] ③ After the concrete is poured, the top groove is pressed with a single channel steel in parallel. When pressing the groove, it is easy to cause problems such as uneven spacing and depth, and crooked lines, which is not conducive to the quality of the appearance of the entity.
