Precast beam construction system and method

Abstract

The invention provides a precast beam construction system. A supporting assembly comprises a plurality of first supporting bodies, the first supporting bodies are fixedly connected to the portion between first bottom dies and a base table, a gap is formed between every two adjacent first supporting bodies, and at least one gap is a hoisting portion; a die further comprises a second bottom die, the second bottom die is fixedly arranged in the hoisting portion, the two ends, in the extending direction of a precast beam, of the second bottom die abut against the ends of the adjacent first bottom dies respectively, and the edges of the two sides of the upper surface of the second bottom die abut against the bottoms of two side dies; the supporting assembly, a bridge plate and the die are sequentially laid on the base table from bottom to top, and the longitudinal length and the transverse width of a precast pedestal can be freely adjusted according to the length and the width of the precast box beam; and meanwhile, the hoisting portion is arranged in the construction system, all assemblies laid in the hoisting portion are independent of non-hoisting portions, therefore the precast beam can be exposed only by detaching all the assemblies laid in the hoisting portion, and hoisting is facilitated.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a prefabricated beam construction system and construction method. Background technique [0002] The side section of the construction system, the side section of the construction system in the hoisting state, the front section of the non-lifting section of the construction system, the front section of the hoisting section of the construction system, the three-dimensional view of the support components, and the three-dimensional view of the grout stop components [0003] In the construction of expressway bridges in our country, prefabricated beams play a very important role, most of which are prefabricated small box girder structures. Under normal circumstances, the production of prefabricated beam structures needs to be completed in the beam manufacturing yard, and the corresponding prefabricated pedestal needs to be pre-installed first. [0004] At present, prefabric...

AI Technical Summary

Problems solved by technology

[0006] (1) The prefabricated pedestal has a long period from the beginning of production to putting into use, and there are a lot of processes such as steel bar binding, concrete pouring and maintenance, which delay the construction period, make the construction complicated, and the cost is high;

[0007] (2) When constructing prefabricated beams of different lengths or different widths, prefabricated pedestals of different sizes need to be erected, the process steps are complicated, and the production cost is increased;

[0008] (3) When the construction is completed and the prefabricated beam body is lifted, the prefabricated pedestal needs to be removed; when a new prefabricated beam is re-constructed, the prefabricated pedestal needs to be erected again, repeating the work, and further prolonging the construction period, which increases the production cost
