Abstract
The utility model relates to a connection node constructional member of a reinforced concrete beam and a steel beam, which belongs to the technical field of constructional engineering and composite structures. The node is composed of the reinforced concrete beam, the U-shaped groove and the steel beam, the U-shaped groove is formed by welding three steel plates, and studs are welded on the steel plates so as to guarantee reliable connection of the reinforced concrete beam and the U-shaped groove. The steel beam is welded on the vertical steel plates of the U-shaped groove, and the two vertical steel plates of the U-shaped groove are connected through bolts and used for resisting drawing force of a steel beam flange on the steel plates. The connection node constructional member of the reinforced concrete beam and the steel beam is excellent in stress performance, safe, reliable and convenient in construction.
Description
Technical field
The utility model relates to the connected node of a kind of reinforced concrete beam and girder steel, belongs 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.
The utility model content
The purpose of the utility model is to overcome deficiency of the prior art, proposes a kind of reinforced concrete beam and girder steel and connects structure and job practices thereof by node, makes the connected node stress performance of reinforced concrete beam and girder steel superior, safe and reliable, easy construction.
A kind of reinforced concrete beam of the utility model and the member of 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 utlity model has following advantage:
(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 weldering of girder steel can be accomplished in factory by work 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.

The specific embodiment
Below in conjunction with accompanying drawing, the practical implementation method of the utility model is further described.
The utility model is the member of the connected node of a kind of reinforced concrete beam and girder steel, and its stress performance is superior, safe and reliable, easy construction.As shown in Figure 1, this node comprises reinforced concrete beam 1, U-lag 2 and girder steel 3.Described U-lag 2 is welded by two blocks of vertical steel plates 6 and a horizontal steel plate 7, is welded with peg 5 on the steel plate in the U-lag, is used to guarantee that described reinforced concrete beam 1 is connected with the reliable of U-lag 2.Said girder steel 3 is welded on vertical steel plate 6 outsides of U-lag 2, and two blocks of vertical steel plates 6 of U-lag 2 connect through bolt 4, are used to resist the pulling force of 3 pairs of vertical steel plates 6 of girder steel.
The job practices of the member of a kind of reinforced concrete beam of the utility model and the connected node of girder steel is:
A. in factory with two blocks of vertical steel plates 6 and a horizontal steel plate 7 U-lag that is welded, on the inboard steel plate of U-lag, weld peg 5, be used to guarantee reliable connection of said reinforced concrete beam 1 and U shape groove 2.Said girder steel 3 is welded on the vertical steel plate 6, and installs bolt 4, and is as shown in Figure 2.
The above-mentioned member that b. will process 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, accomplish construction.
Claims (1)
1. the member of reinforced concrete beam and girder steel connected node is characterized in that this node comprises reinforced concrete beam (1); And 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).
