Movable bottom formwork trolley system suitable for large concrete prefabricated component and method for prefabricating base plate of large concrete component

Abstract

The invention provides a movable bottom formwork trolley system suitable for a large concrete prefabricated component. The movable bottom formwork trolley system comprises multiple movable bottom formwork trolleys and multiple H-bars. A locating groove is formed between the adjacent H-bars. The movable bottom formwork trolleys are arranged in the locating grooves. Each movable bottom formwork trolley comprises multiple bottom formwork trolley units which are connected in series and at least one bottom formwork steel plate with the surface coated with release agent, wherein the bottom formwork steel plates are independent of the bottom formwork trolley units. Each bottom formwork trolley unit comprises multiple sets of bearing devices, multiple pairs of traveling wheels and a formwork lifting device. The formwork lifting devices are connected with the bearing devices, located below the bottom formwork steel plates and used for lifting or descending the bottom formwork steel plates, so that in concrete pouring process, the top surfaces of the bottom formwork steel plates and the top surfaces of wing plates of the H-bars are located on the same plane, and therefore a bottom formwork plate of the large concrete component can be formed. Through different splicing combinations, the prefabricated bottom formworks can be formed for the large concrete prefabricated component of different types and sizes, the bottom formwork can be quick spliced and detached and also can be used for transfer of the component is also considered.

Description

technical field [0001] The invention patent relates to the technical field of construction of large concrete prefabricated components. Background technique [0002] Large concrete prefabricated components (such as large caissons of gravity wharves, concrete beam-slab columns and piers, etc.) are bulky and self-heavy. After prefabrication, mobile devices need to be placed between the components and the ground to carry out component translation. The bottom form structure in the prefabrication process of large concrete components must fully consider the movement of components after prefabrication while satisfying the prefabrication of components. The transportation of large concrete prefabricated components is generally carried out by placing airbags or trolleys in the reserved grooves at the bottom of the components, lifting the components and removing the support, and then moving. Therefore, the bottom form of this structure not only requires a certain strength, rigidity and...

AI Technical Summary

Problems solved by technology

[0007] (1) Low degree of mechanization

The degree of mechanization of formwork installation is low, the assembly efficiency is low, and the quality is difficult to guarantee;

[0008] (2) Template turnover efficiency is low

The template removal process is complicated, the turnover speed is slow, multiple sets of templates are required, and the investment is high;

[0009] (3) Formwork removal is complicated

The removal of the bottom formwork needs to cooperate with the air bag or trolley jacking process, which is complicated;

[0010] (4) Low efficiency of component prefabrication

Due to the complex processing process of the bottom mold structure, the efficiency of component prefabrication is reduced;

[0011] (5) Large labor demand

Formwork assembly and dismantling procedures are complicated and require a lot of labor
