A kind of reinforced truss concrete prefabricated part

Abstract

The invention discloses a reinforced truss concrete prefabricated part, which includes a top layer, an intermediate layer and a bottom layer, and the top layer includes a first series of steel bar groups, a second series of steel bar groups, a third series of steel bar groups and top concrete blocks. The first series of reinforcement groups and the upper vertex of the rhombus slab are fixedly connected by welding, the second series of reinforcement groups and the vertices on both sides of the rhombus slab are fixedly connected by welding, and the third series of reinforcement groups and the lower vertex of the rhombus slab are fixedly connected by welding. The axes of a series of reinforcing bar groups, the second series of reinforcing bar groups and the third series of reinforcing bar groups are parallel in space; the top layer includes the fourth series of reinforcing bar groups, the middle concrete block and the fifth series of reinforcing bar groups; the bottom layer Including the sixth series of reinforcement groups, the bottom concrete block and the seventh series of reinforcement groups. The technical solution disclosed by the invention effectively solves the technical problems in the prior art, such as lack of shock resistance and difficult assembly, and is beneficial to popularization and application of the device.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a reinforced truss concrete prefabricated part. Background technique [0002] Reinforced truss concrete prefabricated parts, truss prefabricated parts made of reinforced concrete or prestressed concrete materials. Reinforced concrete trusses are mostly used for roof trusses, towers, and sometimes trestles and crane beams. Because the tie rods of reinforced concrete trusses often crack under the load, they are only used for trusses with light loads and small spans. The truss is a structure formed by connecting rods at both ends with hinges. The truss is composed of straight rods and generally has a plane or space structure of triangular units. The truss members mainly bear axial tension or pressure, so that the strength of the material can be fully utilized. When the span is large, it can save materials compared with solid web beams, reduce self-weight and Incr...
