Description
Technical field
This practicality relates to industry and residential construction area, is specially the syndeton of a kind of concrete prefabricated beam and girder steel.
Background technology
Floor concrete secondary beam is generally the form of being articulated and connected, and the shortcoming of on-the-spot articulated manner is, mid span moment value, and beam internal stress is distributed uneven, broad in the middle, narrowing toward each end, and beam does not give full play to the effect of total cross-section; The rigidity value be articulated and connected is less, and mid-span deflection is larger; Meanwhile, field operation needs the labour of at substantial and long in time limit, and along with rising steadily of labor cost, the extensive build process of the tradition based on field operation seriously hinders the construction of low-carbon (LC), harmonious society.
Structurally, traditional concrete building structures, when span is larger, deck-molding and arrangement of reinforcement can increase thereupon; When deck-molding is restricted, bottom post Netcom Chang Buhui is very large, and the more architecture indoor of pillar is separated with apparatus arrangement dumb, the property transformed and usability poor.
In sum, a kind of new building technology is provided, node connecting structure is improved simultaneously, in order to solve the drawback of above-mentioned conventional concrete building structure, accomplish advanced technology, economical rationality, safe and applicable, seem particularly necessary.
Summary of the invention
For the problems referred to above, this practicality provides the syndeton of a kind of concrete prefabricated beam and girder steel, and its main technical scheme is as follows:
The syndeton of a kind of concrete prefabricated beam and girder steel, it comprises the concrete composite beam (1) and prefabricate steel structure girder (2) cast in advance, described concrete composite beam (1) is installed between adjacent girder, the body of described concrete composite beam (1) bearing of trend is provided with built-in fitting (3), described built-in fitting (3) forms and extends to concrete composite beam (1) outside and the junction plate I (31) supplying steel structure girder (2) in position, junction plate II (32), junction plate I (31), junction plate II (32) is arranged in the bilateral symmetry of concrete composite beam (1) bearing of trend, in junction plate I (31), junction plate II (32) forms respectively bolt hole I (33), the bolt hole II (21) suitable with bolt hole I (33) is formed respectively in the two ends of steel structure girder (2) bearing of trend, in bolt hole I (33), concrete composite beam (1) and steel structure girder (2) are fixed as criss-cross construction by the high-strength bolt (5) connected between bolt hole II (21).
As preferably, further improve and be, the top side of described concrete composite beam (1) bearing of trend is evenly equipped with exposes stirrup (11), be evenly equipped with the negative reinforcement (4) extended along concrete composite beam (1) in the bottom side of exposing stirrup (11), described in expose stirrup (11) and negative reinforcement (4) by tying up or being welded and fixed.
As preferably, further improve and be, described steel structure girder (2) is work shape girder steel, described bolt hole I (33) is along the web height direction spaced set of work shape girder steel, and end and the built-in fitting (3) on the upper and lower edge of a wing of described work shape girder steel are welded and fixed.
The beneficial effect of this practicality is:
(1) in syndeton, built-in fitting is reserved with on the body of concrete composite beam, the junction plate be connected as a single entity with built-in fitting is connected the steel structure girder of both sides respectively, node adopts high-strength bolt fastening, steel structure girder edge of a wing end solder design, make prefabricated girder steel form beam structure form, significantly improve the rigidity of structure and node;
(2) form of structure of continuous beam, substantially reduces the absolute value of moment of flexure in girder span, and beam internal stress is distributed more evenly rationally, thus reduces material usage and dead load, reduce the internal force of dead load, the moment that joist support is carried on a shoulder pole reduces further;
(3) ensure that component quality greatly by precast beam, compared with traditional syndeton, the duration can shorten, and workmanship is improved simultaneously, and safety significantly promotes, and comprehensive benefit is extremely remarkable.
