Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building engineering, and particularly relates to a variable pile cap formwork. BACKGROUND

[0002] The pile cap is the contact part of the pile and the column or the pier, and refers to a reinforced concrete platform arranged on the top of the foundation pile to connect the tops of the piles, for bearing and distributing the load transmitted by the pier body of the bridge. The pile cap formwork is a steel formwork used for pouring the platform. In recent years, large residential areas and urban complexes and other building groups have sprung up like mushrooms in China, and engineering projects have the characteristics of large size, large scale and large basement area. At present, most of the basement foundation construction of buildings nationwide adopts prestressed pipe pile foundation or cast-in-place pile foundation under the condition of allowing, and the size of the upper pile cap is moderate. In the construction of the pile cap formwork, the common method at present is to use brick blocks to build a brick membrane.

[0003] At present, the pile cap formwork used in building engineering is relatively troublesome to assemble, and workers need to use tools to connect the bolts with the formwork, which is time-consuming and laborious, resulting in low assembly efficiency of the pile cap formwork, which may affect the construction progress of the building engineering. In addition, when the pile cap formwork connected by bolts is used to pour concrete into the interior of the pile cap formwork, the fluid concrete is easy to contact the bolts. When the concrete solidifies, the bolts and the concrete are fixed together, so that the pile cap formwork cannot be disassembled by the conventional disassembly method when it needs to be disassembled, and the pile cap formwork needs to be violently disassembled, which may cause damage to the pile cap formwork, so that the pile cap formwork cannot be used again, resulting in an increase in the cost of building construction. In addition, before pouring concrete, the pile cap formwork needs to be supported around, and the existing pile cap formwork needs workers to use a support column to press against the pile cap formwork at one end, and insert the other end of the support column into the ground of the building construction, which is not only troublesome to operate, but also unstable in fixation and uneven in stress, which may cause damage to the pile cap formwork.
