Novel efficient assembly-type reinforced concrete composite beam

Abstract

The invention discloses a novel efficient assembly-type reinforced concrete composite beam, and belongs to the technical field of bridge construction. The novel efficient assembly-type reinforced concrete composite beam comprises a concrete bridge deck and a steel girder; the concrete bridge deck is arranged on the steel girder; a top flange plate of the steel girder is fixedly connected with a ribbed plate extending in the vertical direction of the steel girder; the bottom of the concrete bridge deck is provided with a channel extending in the vertical direction of the steel girder; the ribbed plate is arranged in the channel; two side edges of the top flange plate are fixedly connected with rubber sealing strips extending in the vertical direction of the steel girder; the bottom surface of the concrete bridge deck is in lap joint with the rubber sealing strips; the top flange plate, the rubber sealing strips, the bottom surface of the concrete bridge deck, and the channel of the concrete bridge deck defines a grouting channel; and the grouting channel is filled with a high-strength pouring sealant material. According to the invention, a series of problems brought by processing of reinforced concrete connecting pieces and cast-in-place of jointed concrete are effectively avoided, the construction quality is guaranteed, at the same time, the on-site work efficiency is improved, and the novel efficient assembly-type reinforced concrete composite beam is more environmentally friendly, and has good economic benefits.

Description

technical field [0001] The invention relates to a novel steel-concrete composite beam, which belongs to the technical field of bridge construction, in particular to an efficient assembled steel-concrete composite beam that does not require on-site concrete pouring. Background technique [0002] In the field of bridge construction, the steel-concrete composite structure can effectively reduce its own weight, improve the spanning capacity, and has a wide range of applications and prospects. [0003] In the composite structure of steel and concrete, connectors are usually used to combine the two together, as shown in the figure figure 1 , figure 2 and image 3 There are three kinds of connectors shown in: welding stud connectors, perforated plate connectors and section steel connectors, among which welding stud connectors are the most widely used. The combined construction in the steel-concrete composite structure usually adopts the method of post-cast welding stud reserved...
