Abstract
The invention discloses a prefabricated balcony connecting structure with steel trusses. The prefabricated balcony connecting structure comprises a prefabricated balcony panel, prestress composite slabs, prefabricated beams and steel trusses, wherein the prefabricated balcony panel comprises a prefabricated balcony panel carrying steel which protrudes and is arranged in the prestress composite slabs; the steel trusses are transversely and uniformly arranged in the prestress composite slabs,and are perpendicular to prefabricated beams on two sides; the steel trusses and the prestress composite slabs are crossed and fixed in an anchoring manner. According to the invention, the steel trusses are arranged on the prefabricated prestress composite slabs of the main structure and positioned in the connection range of prefabricated balcony steel bars and the prestress composite slabs, and the carrying steel of the prefabricated balcony panel is anchored into upper chord reinforcements of the steel trusses, so that the anchoring reliability of the balcony carrying steel is enhanced, the safety of the prefabricated balcony panel is ensured, and security incidents of overturn and falling off of a projecting balcony due to construction can be effectively avoided.
Description
Technical field
The present invention relates to a kind of prefabricated balcony syndeton that contains steel bar girder, belong to industrialization of construction industry and prefabricated mounting technology.
Background technology
Prefabricated balcony is the important content of industrialization of construction industry, the superimposed plank frame of the general employing of the members such as outer cantilevered balcony of present prefabricated assembling building.The pre-erection of superimposed sheet can be used as the balcony slab bed die, and the principal rod of balcony places in the in-situ layer of superimposed sheet.So both can save scaffold and the template of balcony formwork, also be convenient to being connected of balcony and agent structure.
But prefabricated superimposed balcony slab is connected with agent structure, is the very high construction technology of security requirement, connects badly, can cause serious accidents such as balcony topples, comes off.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, a kind of prefabricated balcony syndeton that contains steel bar girder is provided, at the precast prestressed superimposed sheet of agent structure truss bars is set, strengthen the reliability that prefabricated superimposed balcony slab principal rod is connected with agent structure.
The present invention is achieved through the following technical solutions:
A kind of prefabricated balcony syndeton that contains steel bar girder, comprise prefabricated balcony slab, prestressing force superimposed sheet, precast beam, the prestressing force superimposed sheet is connected setting with prefabricated balcony slab, the both sides of prestressing force superimposed sheet are fixedly installed on the precast beam, described prefabricated balcony slab comprises prefabricated balcony slab principal rod, and prefabricated balcony slab principal rod stretches out to be located in the prestressing force superimposed sheet; Also comprise steel bar girder, steel bar girder laterally evenly is arranged in the prestressing force superimposed sheet and perpendicular to the precast beam of both sides, and steel bar girder and prefabricated balcony slab principal rod intersect anchoring.
Described prestressing force superimposed sheet comprises the prestressing force superimposed sheet preformed layer of prestressing force superimposed sheet in-situ layer and its below, is provided with prefabricated superimposed sheet principal rod in the prestressing force superimposed sheet preformed layer, and steel bar girder is connected with prefabricated superimposed sheet principal rod simultaneously.
Described steel bar girder is that two lateral buckling reinforcing bars are welded, the cross section is triangular in shape, comprise the lower edge muscle of wind up muscle and bottom on top and lower edge muscle both sides toward the web member muscle of outside sweep, wind up muscle and prefabricated balcony slab principal rod intersect anchoring, and the lower edge muscle is connected with prefabricated superimposed sheet principal rod.
The technique effect that the present invention brings has:
The reliability that is connected with agent structure for the steel bar stress that guarantees the prestressing force superimposed sheet, on the precast prestressed superimposed sheet of agent structure of the present invention in the scope that links to each other with prefabricated balcony slab reinforcing bar, be provided with steel bar girder, the principal rod of prefabricated balcony slab is anchored in the winding up of steel bar girder, strengthened the reliability of balcony principal rod anchoring, guarantee the safety of prefabricated balcony slab, effectively avoid the security incident of toppling, coming off because of outer cantilevered balcony that construction reason causes.

The present invention can be applicable to structural system and adopts fully-prefabricated assembled framework-steel support structure system, main body frame except basement and bottom overhead layer post adopt cast-in-place, all the other structure divisions all adopt the fabricated assembly overall technology.
The steel bar girder that the present invention is set, its lower edge muscle is positioned at prestressing force superimposed sheet preformed layer 31, the muscle that winds up is positioned at prefabricated balcony slab in-situ layer 32, prefabricated balcony slab principal rod 33 is anchored in the muscle 7 that winds up of steel bar girder, can guarantee the concrete of reliability that prefabricated balcony slab principal rod is connected with main body and in-situ layer to the effect that bonds of prefabricated superimposed balcony slab principal rod, the reliability that reinforcing steel bar connects.
The course of work:
1. when making the prestressing force superimposed sheet of agent structure, the lower edge muscle of steel bar girder is positioned at the preformed layer of superimposed sheet, the muscle that winds up is positioned at the in-situ layer of superimposed sheet;
2. behind the on-the-spot prestressing force superimposed sheet hoisted in position, the principal rod of prefabricated balcony slab is anchored in the muscle that winds up of steel bar girder;
3. the prestressing force superimposed sheet of cast in situs agent structure and the in-situ layer of prefabricated balcony slab.
