Abstract
The invention relates to a member for a connection node of a reinforced beam and a steel beam and a construction method thereof, which belong to the technical field of building engineering and combined structures. The node is composed of the reinforced beam, a U-shaped groove and the steel beam, wherein the U-shaped groove is formed by welding three steel plates, studs are welded on the steel plates, and connection between the reinforced beam and the U-shaped groove is guaranteed to be reliable. The steel beam is welded on vertical steel plates of the U-shaped groove, and the two vertical steel plates of the U-shaped groove are connected through bolts and are used for resisting pull force of the flange of the steel plate on the steel plates. The member for the connection node of the reinforced beam and the steel beam is excellent in stressed performance, safe and reliable and convenient to construct.
Description
Technical field
The present invention relates to the connected node of a kind of reinforced concrete beam and girder steel, belong to construction work and combining structure technical field.
Background technology
Along with the continuous development of high building structure form, many new structural systems have appearred.In the combination construction system, sometimes can run into reinforced concrete beam and the interlaced situation that is connected of girder steel.In order to guarantee between reinforced concrete beam and the girder steel transmission internal force reliably, both connected nodes must have rational structural form.And the present forms of the reinforced concrete beam in the engineering and the pre-buried reinforcing bar of the many employings of girder steel connected node, pre-buried reinforcing bar passes the stirrup colligation in the reinforced concrete beam and vertical muscle and has brought very big difficulty, influences construction quality.
Summary of the invention
The objective of the invention is to overcome deficiency of the prior art, propose the structure and the job practices thereof of a kind of reinforced concrete beam and girder steel connected node, make the connected node stress performance of reinforced concrete beam and girder steel superior, safe and reliable, easy construction.
The member of a kind of reinforced concrete beam of the present invention and girder steel connected node is characterized in that this node comprises reinforced concrete beam 1; With girder steel 3, it is characterized in that, also comprise a U-lag 2; Described U-lag 2 is welded by two blocks of vertical steel plates 6 and a horizontal steel plate 7; Be welded with peg 5 on the steel plate in the U-lag, two blocks of vertical steel plates 6 in the described U-lag outside are welded with girder steel 3 respectively, and described two blocks of vertical steel plates 6 connect through bolt 4.
The job practices of the member of a kind of reinforced concrete beam of the present invention and girder steel connected node is characterized in that step is following:
A. with two blocks of vertical steel plates 6 and a horizontal steel plate 7 U-lag 2 that is welded, weld stud 5 on the inboard steel plate of U-lag, two blocks of vertical steel plates 6 in the U-lag outside are welded steel beams 3 respectively, and install bolt 4;
B. the member that a step is processed is transported to the job site installation in position;
C. the reinforcing bar of assembling reinforcement concrete beam, concreting;
D. when concrete intensity reaches design load, tight a bolt 4, accomplish construction.
The present invention has the following advantages:
(1) reasonable stress.This connected node transmits the shearing between reinforced concrete beam and the girder steel through peg, through the pulling force of the bolt opposing girder steel edge of a wing to the vertical steel plate of U-lag, has guaranteed effective transmission of stress, connects reliable.(2) easy construction.U-lag, the welding job of girder steel can be accomplished in factory in advance, and U-lag can be used as the template of reinforced concrete beam and uses, direct in the above concreting, it is very convenient to construct.
