Steel bar truss concrete prefabricated member

Abstract

The invention relates to the field of road engineering construction, in particular to a steel bar truss concrete prefabricated member. The steel bar truss concrete prefabricated member comprises fixing structures, first limiting structures, prefabricated member bodies, truss structures, grouting structures and second limiting structures; the first limiting structures are arranged on the two opposite edges of the prefabricated member bodies, through arrangement of the first limiting structures, mounting of the two prefabricated member bodies is more stable, the integrity of the two adjacent prefabricated member bodies is higher, deviation of joints in the concrete pouring process is avoided, the waterproof performance is improved, using in the slope area with much rainwater is convenient, the second limiting structures are arranged on the other two side edges of the prefabricated member bodies, semi-flexible semi-rigid connection is further adopted between the adjacent prefabricated member bodies, thus connecting between the two adjacent prefabricated bodies is tighter, template using in the adjacent prefabricated member body mounting process is avoided, meanwhile connecting betweenthe two adjacent prefabricated bodies is tighter, and thus the anti-pressure capacity is higher in the pouring process.

Description

Technical field [0001] The invention relates to the field of prefabricated parts for road engineering construction, in particular to a reinforced truss concrete prefabricated part. Background technique [0002] The reinforced truss floor deck is composed of steel bars, trusses and concrete slabs. It is a new building material based on the profiled floor deck. The reinforced truss is shaped and processed in the background processing plant, and can be prefabricated in length. Gold welding, silanization, pure manganese phosphating, washing and drying, galvanizing and other rust-removing and anti-rust technology, anti-rust film winding and sealing, on-site construction requires the truss floor deck to be placed in the correct position, and the supporting steel bars are welded , After welding the studs, place the on-site steel bars for binding, and then pour the concrete. [0003] However, after road construction in areas with a lot of rain in the south, if both sides of the excavated ...

AI Technical Summary

Problems solved by technology

[0003] However, after road construction in areas with a lot of rain in the south, if the sides of the excavated road are not supported in time, it will cause soil loss or even mudslides. The traditional method is to cover both sides of the road excavation area Mesh film prevents rainwater from impacting on both sides of the road. It has no supporting effect on the mountain slopes on both sides of the road, and the anti-impact effect is poor. At the same time, it needs secondary construction. Spraying concrete on the higher mountains on both sides of the road is harmful to the weather. The requirements are high, and the traditional reinforced truss concrete prefabricated parts cannot meet the construction in the rainy weather in the south, and the reinforced truss concrete prefabricated parts are poor in stability during the splicing process, and support formwork is required, which is not convenient for use in steep slope areas. It is not convenient to pour between the prefabricated concrete parts and the mountain, and it is not convenient for large-scale pouring
