Description
Technical field
The present invention relates to industry and residential construction area, specially a kind of connection structures of concrete prefabricated beam and girder steel.
Background technology
The shortcomings that floor concrete secondary beam is usually articulated connection form, live articulated manner be, mid span moment value, beam
Internal stress distribution is uneven, and broad in the middle, narrowing toward each end, beam does not give full play to the effect of total cross-section；The rigidity value of articulated connection is smaller, across
Middle amount of deflection is larger；Meanwhile field operation needs to expend a large amount of labour and long in time limit, with labor cost it is continuous on
Rise, the extensive building technology of the tradition based on field operation has seriously hindered the construction of low-carbon, harmonious society.
In structure, traditional concrete building structures deck-molding and increase therewith when span is larger with influential point of tendons；Work as beam
When height is restricted, bottom column Netcom Chang Buhui is very big, and the more architecture indoor separation of pillar and equipment arrangement are dumb, can be transformed
Property is poor with usability.
In conclusion providing a kind of new building technology, while node connecting structure is improved, it is above-mentioned to solve
The drawbacks of conventional concrete building structure, accomplishes technologically advanced, economical rationality, safe and applicable, it appears particularly necessary.
Invention content
In view of the above-mentioned problems, the present invention provides a kind of connection structure of concrete prefabricated beam and girder steel, main skill
Art scheme is as follows：
A kind of connection structure of concrete prefabricated beam and girder steel comprising the concrete composite beam (1) and work cast in advance
The prefabricated steel structure girder of factory (2), the concrete composite beam (1) are installed between adjacent girder, the concrete composite beam
(1) ontology of extending direction is equipped with built-in fitting (3), and the built-in fitting (3), which forms, extends to concrete composite beam (1) outside
And for connecting plate I (31), connecting plate II (32) that steel structure girder (2) is secured in position, connecting plate I (31), connecting plate II (32) in
The both sides of concrete composite beam (1) extending direction are arranged symmetrically, and have been separately formed on connecting plate I (31), connecting plate II (32)
Bolt hole I (33) has been separately formed the compatible bolt hole with bolt hole I (33) in the both ends of steel structure girder (2) extending direction
II (21), the high-strength bolt connected between bolt hole I (33), bolt hole II (21) (5) is by concrete composite beam (1) and steel knot
Structure beam (2) is fixed as criss-cross construction.
Preferably, further improve is that the top side of concrete composite beam (1) extending direction is evenly equipped with
Exposed stirrup (11) is evenly equipped with the negative reinforcement (4) extended along concrete composite beam (1) in the bottom side of exposed stirrup (11),
The exposed stirrup (11) is with negative reinforcement (4) by tying up or being welded and fixed.
Preferably, further improve is, the steel structure girder (2) is I-shaped steel and steel beam, the bolt hole I
(33) along the web height direction spaced set of I-shaped steel and steel beam, end and the built-in fitting (3) on the upper and lower edge of a wing of I-shaped steel and steel beam
It is welded and fixed.
The beneficial effects of the invention are as follows：
(1) it in connection structure, in being reserved with built-in fitting on the ontology of concrete composite beam, is linked together with built-in fitting
Connecting plate is separately connected the steel structure girder of both sides, and node is fastened using high-strength bolt, and steel structure girder edge of a wing end solder design makes
Prefabricated girder steel forms beam structure form, significantly improves structure and the rigidity of node；
(2) structure type of continuous beam substantially reduces the absolute value of moment of flexure in girder span, keeps the distribution of beam internal stress more equal
It is even rationally to reduce material utilization amount and dead load, to reduce the internal force of dead load, so that the moment that joist support is carried on a shoulder pole is further decreased；
(3) component quality greatly ensure that by precast beam, compared with traditional connection structure, the duration can shorten, together
When construction quality be improved, safety is substantially improved, and comprehensive benefit is extremely notable.
