Abstract
The present invention relates to a totally assembled type prefabricated concrete structure system which comprises a prefabricated pole, a prefabricated beam and a short overhanging beam, wherein the prefabricated pole and the short overhanging beam form a whole assembly of the prefabricated pole and the short beam, the short overhanging beam is fitted and fixed with a joint of the junction surface of the prefabricated beam, and the prefabricated beam, the short overhanging beam and the prefabricated pole are spliced on the scene. The junction part of the prefabricated beam and the prefabricated pole is directly positioned on the side surface of the prefabricated pole no longer by adding the short overhanging beam and can be adjusted according to concrete stress conditions during construction to avoid the most unfavorable stress sectional plane. The present invention has the advantages of reliable theory bases, reasonable structure, convenient construction, etc. Besides, required components are large-scale production suitable for the large-scale production of factories for prefabrication.
Description
Technical field
The present invention relates to precast concrete design and construction field, particularly complete prefabricated concrete structure system.
Background technology
At present, the common way of the bean column node of prefabricated concrete structure is that vertical posts directly is connected at position of joints with horizontal beam.The beam column juncture of the bent structure of common single storey industry workshop is: precast beam is sat put at vertical prefabricated column cap earlier, joint is positioned at the post upper surface, uses built-in fitting, bolt or reserved steel bar anchoring then; This connection way precast beam and prefabricated post can rotate relatively freely, thereby energy dissipation capability is relatively poor, and be unfavorable to opposing impact load or geological process.And to the prefabricated frame construction of general multilayer, the bonding land is positioned at beam-ends, and Liang Yuzhu makes rigidly connected form usually, but because joint is located immediately at the vertical posts side, this place often is the stressed cross section of least favorable, is easy to go beyond the limit of supporting capacity, causes destroying; Although structure has energy dissipation capability preferably, owing to a little less than the relative thin of bonding land, be easy to generate destruction than its position of Liangqi, thereby the bonding land is required height, corresponding cost improves, and is uneconomical.The bean column node of prestressing force prefabricated concrete structure normally applies prestressing force and forms the friction node, and beam column is formed integral body, and need apply prestressing force is one of principal character of this kind structural engagement method.
Summary of the invention
The object of the present invention is to provide a kind of connection reliable, stressed rationally have supporting capacity preferably, and the new structure system of good deformability and energy dissipation capability is particularly arranged under impact load or seismic loading.
For achieving the above object, the present invention is achieved in that
A kind of complete prefabricated concrete structure system, comprise prefabricated post, precast beam, also comprise the short beam of encorbelmenting, described prefabricated post and the described short beam of encorbelmenting constitute prefabricated post-short beam composite member integral body, and the bonding surface joint of described encorbelment short beam and described precast beam coincide and be fixing.The bonding surface joint of described encorbelment short beam and described precast beam forms the stepped form that convex-concave interlaces, and implants engagement recesses relatively with engagement lugs.
Preferable, the bonding surface joint of described encorbelment short beam and described precast beam is buried pre-embedded steel slab respectively underground.
Preferable, the bonding surface joint of described encorbelment short beam and described precast beam forms the sloping section of certain angle, overlaps mutually, and the angle of inclination of sloping section can be determined according to stressed and actual conditions.
Preferable, the bonding surface joint of described encorbelment short beam and described precast beam is fixed by bolt or pin or rivet.
The invention has the beneficial effects as follows: by the increase short beam of encorbelmenting, the junction surface that makes precast beam and prefabricated post no longer is to be located immediately at the prefabricated post side, but can change the position by adjusting precast beam length, thereby avoid the stressed cross section of least favorable according to concrete stressing conditions of when construction.Precast beam forms with the short beam of encorbelmenting, prefabricated post on-site consolidation, and the whole erection process all is to do operation, has improved working environment, has improved operating efficiency.It is reliable that the present invention has theoretical foundation, rational in infrastructure, easy construction, and required member is fit to advantages such as precast yard's large-scale production.

The specific embodiment
The present invention will be further described below in conjunction with drawings and Examples.
As Fig. 1, Fig. 2, first kind of embodiment of the present invention is: the prefabricated post 1 and the short beam 2 of encorbelmenting are made prefabricated post-short beam composite member.Prefabricated post-short beam composite member, precast beam 4 are by precast yard's production and processing, the size that side, prefabricated post floor place has the short beam 2 of encorbelmenting is identical with precast beam 4 with the reinforcement placement mode, and the joint method of encorbelment short beam 2 and prefabricated post 4 adopts common rigid joint processing method.Form the concavo-convex stepped form that interlaces in the joint of the short beam 2 of encorbelmenting, in order to being connected with precast beam 4, precast beam 4 ends also are processed into the stepped form that the convex-concave corresponding to the short beam 2 of encorbelmenting interlaces, the equal pre-embedded steel slab 5 of all contact surfaces is strengthened, implant engagement recesses with engagement lugs, connect with bolt 3 then.Be convenient construction, the nut place of used bolt 3 forms the sulculus of appropriate depth, does not exceed precast beam 4 upper surfaces topmost with nut and is advisable.
As Fig. 3, Fig. 4, second kind of embodiment of the present invention is: the prefabricated post 1 and the short beam 2 of encorbelmenting are made prefabricated post-short beam composite member.Prefabricated post-short beam composite member, precast beam 4 are by precast yard's production and processing, side, prefabricated post floor place has the size of the short beam 2 of encorbelmenting, the reinforcement placement mode is identical with precast beam 4, and the joint method of encorbelment short beam 2 and prefabricated post 4 adopts common rigid joint processing method.Joint at the short beam 2 of encorbelmenting forms the sloping section with certain slope, and contact surface pre-embedded steel slab 5 is strengthened overlap joint, guarantees that closely the contact back connects with bolt 3, guarantees that bolt shaft is to vertical with the inclined-plane.Be convenient construction, the nut place of used bolt 3 forms the sulculus of appropriate depth, does not exceed precast beam 4 upper surfaces topmost with nut and is advisable.
