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 development of high building structure form, there is many new structural system.In Mixed Architecture, sometimes can encounter reinforced concrete beam and the interlaced situation being connected of girder steel.In order to guarantee between reinforced concrete beam and girder steel transmission internal force reliably, both connected nodes must have rational structural form.And the current reinforced concrete beam and the steel beam connecting joint forms that adopt pre-buried reinforcing bar in engineering, pre-buried reinforcing bar passes the stirrup colligation in reinforced concrete beam and vertical muscle and has brought very large difficulty, affects construction quality. more
Summary of the invention
The object of the invention is to overcome deficiency of the prior art, propose structure and the construction method thereof of a kind of reinforced concrete beam and steel beam connecting joint, 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 steel beam connecting joint, it 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, on steel plate in U-lag, be welded with peg 5, two blocks of vertical steel plates 6 in described U-lag outside are welded with respectively girder steel 3, and two blocks of described vertical steel plates 6 connect by bolt 4.
The construction method of the member of a kind of reinforced concrete beam of the present invention and steel beam connecting joint, is characterized in that, step is as follows:
A. the U-lag 2 that two blocks of vertical steel plates 6 and a horizontal steel plate 7 is welded, weld stud 5 on the steel plate of U-lag inner side, two blocks of vertical steel plates 6 welded steel beams 3 respectively in U-lag outside, and install bolt 4;
B. member a step being processed is transported to 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, complete construction.
The present invention has the following advantages:
(1) reasonable stress.This connected node transmits the shearing between reinforced concrete beam and girder steel by peg, by bolt, resists the pulling force of the 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 complete in advance in factory, and U-lag can be used as the template of reinforced concrete beam and uses, and direct concreting, constructs very convenient in the above.

The construction method of the member of the connected node of a kind of reinforced concrete beam of the present invention and girder steel is:
A. in factory by two blocks of vertical steel plates 6 and a horizontal steel plate 7 U-lag that is welded, on the steel plate of U-lag inner side, weld peg 5, for guaranteeing that described reinforced concrete beam 1 is connected with the reliable of U-lag 2.Described girder steel 3 is welded on vertical steel plate 6, and installs bolt 4, as shown in Figure 2.
B. the above-mentioned member processing is transported to 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, complete construction.
