Description

Technical Field

[0001] The utility model relates to a steel template for a cast-in-place upper crossbeam of a high-pile wharf. Background Art

[0002] Cast-in-place beams are a commonly used structure in water transport projects. They are widely used in dock construction because of their strong and durable structure, good integrity, strong adaptability to load changes, and fast construction speed. As the main structure of the high-pile dock, the dock beam is generally divided into a lower beam 100 and an upper beam 200. The function of the lower beam 100 is to connect the single frame piles into one body, and the function of the upper beam 200 is to connect the prefabricated longitudinal beam 300 and the lower beam 100 into a whole, so that the dock beam forms an integral frame and is subjected to overall force. Due to the high height and large volume of the beam, the construction of the beam is divided into cast-in-place construction of the upper and lower beams. After the lower beam is cast, the longitudinal beam is installed on the top of the lower beam, and then the upper beam is cast-in-place.

[0003] During the construction of the upper beam, the longitudinal beam is installed first on site, so the upper beam must be divided into several upper beam units. Usually, each upper beam unit needs to be enclosed by a unit template 200A (see Figure 1 and Figure 2 ). Each unit formwork 200A adopts a steel formwork and includes a panel, an inner transverse back rib fixed on the back of the panel, a vertical back rib fixed on the back of the inner transverse back rib, and an outer transverse back rib fixed on the back of the vertical back rib. The panel adopts a 6mm thick steel plate. Each upper beam unit formwork is installed and poured at one time.

[0004] The above unit template will produce the following defects:

[0005] ① Since the longitudinal beams installed on site are prefabricated concrete components, there are horns on both sides of the upper part of the longitudinal beams, which makes the installation of steel formwork on site inconvenient;

[0006] ② There will be a slight error in the installation of the longitudinal beam, and it is impossible to ensure that the size of each longitudinal beam prefabricated component is the same. Therefore, the fitting position of the unit template and the longitudinal beam does not match, and there is a gap.

[0007] ③ When installing the unit formwork, it is easy to collide with individual areas of the longitudinal beam, which may damage the original anti-corrosion coating of the longitudinal beam and is not conducive to the protection of the finished product. Utility Model Content
