A kind of supporting equipment and using method of bridge prefabricated hollow slab side form

Abstract

The invention relates to supporting equipment for a lateral mould and a using method of the supporting equipment, in particular to supporting equipment for a bridge precast hollow slab lateral mould and a using method of the supporting equipment. During the pouring of a hollow slab precast pedestal, after fixing parts are pre-buried under the precast pedestal, the hollow slab lateral mould is supported by a jack and adjusting lead screws. The using method of the supporting equipment comprises the following steps: during the concrete pouring of the hollow slab precast pedestal, the fixing parts are transversely pre-buried in the pedestal concrete at intervals of 1 m; during the use, the hollow slab lateral mould is hoisted on I-steel by hoisting equipment to be close to a pedestal slurry sealing pipe, and then, the bottom of the lateral mould is tightly jacked by the jack every other 1 m; one ends, connected with the lateral mould, of the adjusting lead screws are connected with corresponding small channel bars every other 1 m, the adjusting lead screws are rotated to correct the lateral mould until the lateral mould meets construction requirements. According to the invention, the structure is simple, the mounting and dismounting are facilitated, the use is flexible, the performance is reliable, the controllability and randomness are high, the construction efficiency is high, the waste of manpower and material is reduced, and high safety and reliability are achieved.

Description

technical field [0001] The patent of the present invention relates to a supporting device and a using method of a side form, in particular to a supporting device and a using method of a bridge prefabricated hollow plate side form. Background technique [0002] In the precast construction of bridge prestressed hollow slabs, the traditional method is used to install a 20-meter-long hollow slab side form, which takes more than 2 hours for 5 to 6 people to complete, and the construction efficiency is low, which seriously affects the turnover rate of beam slab prefabricated pedestals. . The traditional installation method is to use wooden wedges and square logs to support the concrete beams poured in advance, but this construction method is likely to cause the side formwork to be not firmly supported, the formwork is easy to run out, leak grout, and the workload of formwork is large.

Problems solved by technology

[0002] In the precast construction of bridge prestressed hollow slabs, the traditional method is used to install a 20-meter-long hollow slab side form, which takes more than 2 hours for 5 to 6 people to complete, and the construction efficiency is low, which seriously affects the turnover rate of beam slab prefabricated pedestals.

The traditional installation method is to use wooden wedges and square logs to support the concrete beams poured in advance, but this construction method is likely to cause the side formwork to be not firmly supported, the formwork is easy to run out, leak grout, and the workload of formwork is large. Almost every time When setting up the formwork, the square wood must be sawed to measure, the turnover rate of the square wood is low, the sawdust is seriously harmful to the human body and the environment, and the site is messy, etc.

This method is cumbersome in the construction process, resulting in a waste of labor and materials, which affects the progress of the construction

[0003] So far, there is no equipment and method to overcome the above defects
