Structure and construction method of T-beam prefabricated field pedestals

Abstract

The invention provides a structure and construction method of T-beam prefabricated field pedestals. A leak-proof slurry device is arranged at the upper ends of the pedestals; a T-beam side formwork split bolt reserving pipe is pre-buried in the upper parts of the pedestals; a bottom mould support device is arranged on a hanging beam between the pedestals; drain grooves are formed in the bases of the pedestals. The structure and construction method of the T-beam prefabricated field pedestals have the advantages that the close fit between a T-beam bottom mould and a side mould is achieved through a sealing rubber pipe in the leak-proof slurry device, the phenomena of leakage, honeycomb and pitted surface occurred in the T-beam pouring process are avoided, the robustness and adherence of theT-beam template are strengthened through the arrangement of the T-beam side formwork split bolt reserving pipe, and a strong fixing effect is achieved for preventing the offset and leakage of the formwork. The bottom mould support device at the position of the hanging beam is convenient to move and can be reused. The height difference can be conveniently adjusted through a screw adjusting rod, andthe placement position is accurate. Drainage can be quickly achieved through the design of a drainage system, the phenomenon of water ponding does not exist, and the construction is not affected.

Description

technical field [0001] The invention relates to a bridge prefabrication field, in particular to a platform structure and a construction method of a T-beam prefabrication field. Background technique [0002] At present, the design of the prefabricated pedestal of the T-beam is unreasonable, the foundation is not properly treated, and there is no drainage design. During the rainy season or during the maintenance of the T-beam, too much water cannot be drained out, resulting in foundation subsidence. In addition, the pedestal has no anti-leakage design, and the connection between the prefabricated formwork of the T-beam and the pedestal is not stable, and it is easy to cause defects in the prefabricated T-beam structure to leak when pouring the T-beam. When there is little slurry leakage, the phenomenon of "burrs" will appear on the bottom edge, and when it is serious, there will be honeycomb pitting. In order to solve the above problems, a T-beam prefabricated pedestal struct...

Problems solved by technology

[0002] At present, the design of the prefabricated pedestal of the T-beam is unreasonable, the foundation is not properly treated, and there is no drainage design. During the rainy season or during the maintenance of the T-beam, too much water cannot be drained out, resulting in foundation subsidence

In addition, the pedestal has no anti-leakage design, and at the same time, the connection between the prefabricated formwork of the T-beam and the pedestal is not stable. When pouring the T-beam, it is easy to cause defects in the prefabricated T-beam structure.
