Steel bar truss concrete precast element

Abstract

The invention discloses a steel bar truss concrete precast element which comprises a top layer, a middle layer and a bottom layer, wherein the top layer comprises a first series of steel bar groups, asecond series of steel bar groups, a third series of steel bar groups and a top concrete block; the first series of steel bar groups are fixedly connected with the upper vertex of a diamond plate ina welding mode, the second series of steel bar groups are fixedly connected with the two side vertexes of the diamond plate in the welding mode, and the third series of steel bar groups are fixedly connected with the lower vertex of the diamond plate in the welding mode; the axes of the first series of steel bar groups, the second series of steel bar groups and the third series of steel bar groupsare parallel in space; the middle layer comprises a fourth series of steel bar groups, a middle concrete block and a fifth series of steel bar groups; and the bottom layer comprises a sixth series ofsteel bar groups, a bottom concrete block and a seventh series of steel bar groups. The technical scheme effectively solves the technical problems in the prior art, such as not having anti-seismic capability and not being easy to assemble, and is conducive to the 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 prefabs, truss prefabs made of reinforced concrete or prestressed concrete materials. Reinforced concrete trusses are mostly used for roof trusses, towers, and sometimes trestle bridges and crane beams. Because the tie rods of reinforced concrete trusses often crack under the load, they are only used for trusses with lighter 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 with triangular elements. 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, the material can be saved compared with the solid web beam, and the weight and weight can be re...
