A kind of reinforced truss concrete prefabricated part

Abstract

The invention relates to the field of road engineering construction prefabricated parts, in particular to a reinforced truss concrete prefabricated part, including a fixed structure, a first limiting structure, a prefabricated part body, a truss structure, a grouting structure and a second limiting structure; prefabricated One of the two opposite sides of the body is provided with a first limiting structure. The setting of the first limiting structure makes the installation of the two prefabricated bodies more stable and makes the integrity between the two adjacent prefabricated bodies stronger. , which avoids the offset of the joint during the pouring of concrete, improves the waterproof performance, and is convenient for use in slope areas with a lot of rain. The second limiting structure is set on the other two sides of the prefabricated body, so that the The semi-flexible and semi-rigid connection between the body parts makes the connection between two adjacent prefabricated body bodies more tightly, avoiding the use of templates during the installation process of adjacent prefabricated body bodies, and making the adjacent prefabricated body bodies The connection between them is tighter, which makes the compressive capacity stronger during the pouring process.

Description

technical field [0001] The invention relates to the field of road engineering construction prefabricated parts, 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 modified on the basis of the profiled floor deck. It is a new building material. The reinforced truss is shaped and processed in the background processing plant. It can be prefabricated to a length. Gold welding, silanization, pure manganese phosphating, washing and drying, galvanizing and other rust removal and anti-rust technology, anti-rust film winding and sealing, on-site construction needs to first place the truss floor bearing plate in the correct position, weld the support steel bar , and then weld the studs, then 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 the...

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
