Description

The steel reinforced concrete frame node
Technical field
The utility model relates to the reinforced concrete structure technology, is a kind of steel reinforced concrete frame node.
Background technology
Steel reinforced concrete frame node commonly used now has following several kinds: (1) steel concrete beam steel connects with short girder steel tower.Its way is one section short girder steel of welding on the H shaped steel edge of a wing, and its length need satisfy the anchoring requirement of beam steel, short girder steel end face weldering two row's peg connectors.Its shortcoming is that the welding job amount is big, expends steel, and construction is complicated, and is stressed not direct.
(2) welded H section steel bracket on the H shaped steel edge of a wing, beam steel is welded on the steel corbel.Its way is a welded H section steel bracket on the H steel column edge of a wing, and the steel concrete beam steel is welded on the H shaped steel bracket.Its shortcoming is that the welding job amount is big equally, expends steel, is inconvenient to construct.Beam steel and bracket edge of a wing welding procedure difficulty.
(3) beam outer corners reinforcing bar directly passes node, and beam middle part reinforcing bar directly passes H shaped steel frange plate, after the frange plate perforation slackens, must take reinforcement measure to it.Though this method power transmission is direct, shortcoming is on H shaped steel frange plate, to bore a hole, and concerning the H steel column, the floor position moment of flexure is maximum, mainly rely on H steel column frange plate to resist moment of flexure, and frange plate has been slackened.Stressed unreasonable, construction is complicated, inconvenience.
Therefore a kind of reasonable stress, steel reinforced concrete frame node simple for production being provided is technical issues that need to address.
Summary of the invention
The technical problem that the utility model solves provides a kind of reasonable stress, steel reinforced concrete frame node simple for production.
For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: a kind of steel reinforced concrete frame node; Comprise H steel column and Vierendeel girder, this H steel column comprises web and two frange plates, and the reinforcing bar of this Vierendeel girder is connected with the frange plate of this H steel column; Wherein: the reinforcing bar of said Vierendeel girder is provided with reinforcing steel bar connecting sleeve tube with the end that said frange plate is connected, and the frange plate welding of this reinforcing steel bar connecting sleeve tube and said H steel column is fixing.
One of improve: be provided with reinforcement between said two frange plates and the said web, this reinforcement is positioned at the junction of the reinforcing bar and the said frange plate of said Vierendeel girder.
Two of improvement: said reinforcement comprises perpendicular to put more energy into floor and be fixedly arranged on adjacent first floor of putting more energy into of second between the floor of putting more energy into of some first of said two frange plates; This first floor of putting more energy into is fixing with the welding of said two frange plates respectively, and this second deep floor and adjacent two first floor welding of putting more energy into is fixed.
Three of improvement: said first floor, said second floor of putting more energy into of putting more energy into is also fixing with the welding of said web respectively.
Compared with prior art, beneficial effect is: (1) significantly reduces the welding job amount owing to need not weld short girder steel, saves a lot of steel, and beam steel directly links to each other with the H steel column through socket wrench specially adapted for it, and power transmission directly, rationally.
(2) owing to do not need the welded H section steel bracket; Need beam steel be welded on the bracket yet; Significantly reduce the welding job amount, save steel and construction period, because beam steel and socket wrench specially adapted for it adopt screwed connection;, beam steel compares this novel joint easy construction, simple with being welded on the bracket.
(3) wear H steel column frange plate with beam steel, on the post frange plate, bore a hole and compare, this novel joint more reasonable stress does not need the coupled columns edge of a wing to take strengthening measure.
In sum, the utility model and existing shaped steel coagulate native frame joint compared with techniques reasonable stress and simple for production, can when reducing production costs, improve production efficiency.

Fig. 3 is the sectional view of the B-B direction of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
As shown in Figure 1, the steel reinforced concrete frame node of present embodiment comprises H steel column 1 and Vierendeel girder 2.
Like Fig. 2, shown in Figure 3, this H steel column 1 comprises web 11 and two frange plates 12, and the reinforcing bar 21 of this Vierendeel girder 2 is connected with the frange plate 12 of this H steel column 1.The end that the reinforcing bar 21 of Vierendeel girder 2 is connected with frange plate 12 is provided with reinforcing steel bar connecting sleeve tube 3, and this reinforcing steel bar connecting sleeve tube 3 is fixing with frange plate 12 welding of H steel column 1.Reinforcing steel bar connecting sleeve tube is called reinforced bar straight thread sleeve or reinforced bar sleeve again, is used for connecting reinforcement and has and the connector of silk head thread corresponding internal thread.Construction process: be processed into straight thread with end reinforced with technique for rolling, and be installed on the end of reinforcing bar with the reinforcing steel bar connecting sleeve tube of corresponding size, the realization sleeve is fixedly connected with reinforcing bar.
As shown in Figure 2, also be provided with reinforcement 4 between two frange plates 12 and the web 11, this reinforcement 4 is arranged on the junction of reinforcing bar 21 with the frange plate 12 of Vierendeel girder 2.This reinforcement 4 comprises perpendicular to put more energy into floor 41 and be fixedly arranged on adjacent first floor 42 of putting more energy into of second between the floor of putting more energy into of some first of two frange plates 12; This first floor of putting more energy into is fixing with the welding of two frange plates 12 respectively, and these second floor 42 and adjacent two first floor 41 welding of putting more energy into of putting more energy into are fixing.In the present embodiment, this reinforcement 4 comprises two first put more energy into floor 41 and one second floors 42 of putting more energy into.In addition, first floor 41, second floor 42 of putting more energy into of putting more energy into is can also be respectively fixing with web 11 welding, with further reinforced frame node structure rigidity.
The steel reinforced concrete frame node of present embodiment is when concrete the making; At first at produce in factory H steel column 1 and reinforcement 4; Simultaneously reinforcing steel bar connecting sleeve tube 3 being carried out screw thread with the reinforcing bar 21 of Vierendeel girder 2 is fixedly connected; In Vierendeel girder 2 formworks and assembling reinforcement 21, reinforcing steel bar connecting sleeve tube 3 is welded on H steel column 1 frange plate 12 then, last, to Vierendeel girder 2 and steel column carry out on-site concrete water smash, maintenance, moulding.
Floor welding and check are all accomplished in factory owing to put more energy into, so welding quality is easy to assurance, are suitable for producing in batches, improve effect.In the steel reinforced concrete frame node, adopted technical measures such as setting up reinforcement, further improved the shock resistance of node, can be applicable in high-rise and the superelevation stratotype steel-concrete structure, made it have the scope of application widely.
