Description

A prefabricated template for a niche-type mooring bollard in an inland waterway lock Technical Field

[0001] This utility model relates to the field of construction technology for inland waterway locks and navigation and hydropower hubs, specifically to a prefabricated template for a niche-type mooring bollard in an inland waterway lock. Background Technology

[0002] In recent years, with the rapid development of the economy and society, my country's inland waterway construction and development has achieved remarkable results, mainly based on the Yangtze River, Pearl River, and Huai River systems, leveraging the advantages of large transport capacity, small land occupation, low energy consumption, and low pollution. In the field of inland waterway locks, structures are usually embedded with embedded parts on a large volume of concrete foundation, and the precision requirements are generally high. However, when embedded parts such as mooring bollards are heavy and large in volume, traditional wooden formwork is difficult to construct, has few reuses, and high construction costs. Integral steel formwork has high production costs, low utilization rate, and is difficult to erect and dismantle. Therefore, it is necessary to design modular steel formwork for construction.

[0003] In the construction of inland waterway locks and navigation and hydropower hubs, wooden formwork is usually used for embedding parts. Wooden formwork is easy to set up and dismantle, has wide operability, and can better shape irregular structures. However, it is basically used only once. After the formwork is removed, it cannot be reused. The number of times it can be reused is small, the construction cost is high, and the wooden formwork cannot effectively guarantee the accuracy of the embedded parts and the surface quality of the concrete surface. Problems such as formwork bulging or grout leakage often occur. Summary of the Invention

[0004] The purpose of this utility model is to address the problems in the prior art mentioned above by providing an assembled template for a niche-type mooring bollard in an inland waterway lock.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a prefabricated template for a niche-type mooring bollard in an inland waterway lock, characterized in that: the prefabricated template for the niche-type mooring bollard includes an embedded template and an outer template that are fixedly connected; the embedded template includes a side mold, a bottom mold, and a niche-type mooring bollard embedded part connected from top to bottom; the side mold includes a left side template, a front upright side template, and a right side template connected from left to right, all of which are irregularly shaped templates that are perpendicular to the surface of the outer template, and after splicing, the entire side mold is a trapezoidal platform structure with a downward-sloping upper surface and a horizontal bottom surface; the bottom mold includes a left bottom mold, a middle bottom mold, and a right bottom mold connected from left to right, each bottom mold being connected below the corresponding side mold and perpendicular to the surface of the outer template, and the niche-type mooring bollard embedded part is connected below the middle bottom mold.

[0006] The side mold, bottom mold, and outer formwork are all connected by bolts, and the various parts of the side mold and the various parts of the bottom mold are also connected by bolts. The left bottom mold and the right bottom mold are both triangular bottom molds, and the middle bottom mold is a rectangular bottom mold. The niche-type mooring bollard is bolted to the pre-reserved holes on the middle bottom mold.

[0007] The templates are connected by grout-stop strips, which are installed along the entire length of the template surface in the template joints to prevent grout leakage during pouring and vibration, thus ensuring the aesthetic appearance of the finished concrete.

[0008] The grout-stopping strip is an EPDM rubber grout-stopping strip or a double-sided adhesive strip with a thickness of not less than 5 mm.

[0009] The external formwork is a large steel formwork, and its actual height is determined based on the amount of concrete in the silo and the pouring method.

[0010] This utility model, designed to facilitate the removal of steel formwork after concrete pouring, disassembles a set of niche-type mooring post prefabricated formwork into six pieces, which are then bolted together. The niche-type mooring post prefabricated formwork serves as an embedded formwork, connected to the outer formwork using bolts. This prefabricated formwork structure reduces damage to the formed concrete, ensuring the accuracy of the embedded parts in the niche-type mooring posts while lowering formwork fabrication and erection costs. The use of this prefabricated formwork solves the problems of limited internal space and high construction difficulty in niche-type structures. It also addresses the issues of limited reuse and high construction costs associated with wooden formwork due to the embedded parts in the niche-type mooring posts, and the difficulty of erecting and dismantling integral steel formwork.
