Precast box beam transverse partition board connecting structure and construction method thereof

Abstract

The invention discloses a precast box beam transverse partition board connecting structure and a construction method thereof. The precast box beam transverse partition board connecting structure comprises a precast concrete box beam single body; the precast concrete box beam single body comprises a precast concrete box beam body; flange plates are arranged on the two sides of a top plate of the precast concrete box beam body; a box beam bottom plate is arranged at the bottom; top plate connecting main reinforcements are pre-embedded in the flange plates; the top plate connecting main reinforcements and the flange plates are integrally poured for forming; the flange plates of two adjacent precast concrete box beam single bodies are connected through a wet joint; rebar connecting sleeves arepre-embedded at the upper and lower parts of the interior of a side plate of each of the precast concrete box beam single bodies; a plurality of transverse partition board horizontal rebars are arranged in the middle; and the two ends of a transverse partition board connecting main reinforcement penetrate through the rebar connecting sleeves in adjacent precast concrete box beam single bodies toconnect adjacent transverse partition boards. The precast box beam transverse partition board connecting structure can effectively avoid dislocation of the transverse partition boards to improve the using efficiency of an integrate formwork and realize the purpose of saving to generate excellent economic and social benefits.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a prefabricated box girder diaphragm connection structure and a construction method thereof. Background technique [0002] In the construction of highway bridges, prefabricated box girders are generally used for erection. In order to strengthen the overall rigidity, the prefabricated box girders are connected with transverse diaphragms. When prefabricating box girders, diaphragms are usually poured together with the girder body. However, during the installation of prefabricated box girders, the phenomenon of dislocation of diaphragms often occurs, especially in the installation of curved bridges and inclined bridges. The main reasons for the dislocation of the diaphragm are: 1) There is a deviation in the external dimension of the prefabricated beam formwork or the direction angle of the diaphragm; 2) There is a deviation in the installation of the diaphragm formwor...

AI Technical Summary

Problems solved by technology

The main reasons for the dislocation of the diaphragm are: 1) There is a deviation in the external dimension of the prefabricated beam formwork or the direction angle of the diaphragm; 2) There is a deviation in the installation of the diaphragm formwork; It will affect the overall appearance of the bridge, and the processing is quite time-consuming and labor-intensive

If the misalignment is serious, it may even affect the function of the bridge

[0003] In addition, when more and more automated beam yards produce prefabricated box girders, the overall hydraulic external formwork is basically used, and the installation and disassembly of the angular diaphragm formwork takes more time and labor, which reduces the efficiency of mechanized operations
