Description
Technical field
The present invention relates to a kind of building structure, and specifically one is girder preformed groove secondary beam back insertion type connecting nodes
Structure.
Background technique
With the continuous development of Urbanization in China and the promotion of energy-saving and environmental protection engineering, more and more prefabricated dresses
It is continuously emerged with formula structural shape, and existing ox load plate tongue and groove beam belongs to articulated connection, connection integrity is poor.Meanwhile it saving
The dislocation being easy to appear between precast concrete primary-secondary beam at point, weakens the integral level rigidity of structure, influences structure level power
Transmitting between each vertical member, and then influence globality, safety and the anti-seismic performance of building.
Ox, which carries on a shoulder pole plate tongue and groove beam, will increase the amount of deflection of secondary beam by hinged calculating, need to cut by increasing beam to reduce time beam deflection
The mode of face or beam bottom reinforcement bars, it is less economical.
Connector of the existing technology is low with the bond strength of beam, and anti-pulling ability is poor, can not be applicable in large-span girder
Top longitudinal reinforcement multi-tier arrangement.
Summary of the invention
The purpose of the present invention is to solve above-mentioned technical problem, provide that a kind of structure is simple, can reach and is equal to primary and secondary
The node of the cast-in-place connection of beam, while primary-secondary beam is able to maintain the girder preformed groove of good globality, safety and anti-seismic performance
Beam back insertion type connecting joint structure.
Technical solution includes girder and secondary beam, and the rear end of the secondary beam is inserted into the preformed groove of girder through ox load plate,
Rectangular aperture sleeve is equipped in the preformed groove of the girder, the rear end of the ox load plate is equipped with postive stop baffle, the postive stop baffle
Correspondence is inserted into rectangular aperture sleeve.
The secondary beam is symmetrically arranged in the two sides of girder in pairs, through height between corresponding symmetrically arranged two rectangular aperture sleeves
Strength bolt connection.
The reserved groove bottom of the girder is equipped with anti-shear steel plate.
The girder and time top surface of the beam are equipped with cast-in-place overlapping layers.
The utility model has the advantages that
1) by the way that rectangular aperture sleeve is arranged in the preformed groove of girder, while limiting block is set in the end of ox load plate
The multidirectional limit of junction may be implemented, thus effectively in plate, the two cooperation after the corresponding insertion rectangular aperture sleeve of postive stop baffle is interior
The problem of misalignment between primary-secondary beam is avoided, the integral level rigidity of structure is increased, ensure that structure level power each vertical
Transmitting between component improves globality, safety and the anti-seismic performance of building；
2) anti-shear steel plate is arranged in the bottom surface of preformed groove, connects between symmetrical rectangular aperture sleeve also by high-strength bolt, into
One step enhances shearing resistance, antidetonation and the tensile property of junction；
3) globality of precast construction is further enhanced by the cast-in-place overlapping layers that prefabricated primary and secondary top surface of the beam is arranged；
4) the utility model structure is simple, and globality and stress performance are preferable, and the welding without scene, labour cost
Low, quick construction can be obviously shortened the duration, be suitable for large-span girder top longitudinal reinforcement multi-tier arrangement.

Specific embodiment
Explanation is further explained to the utility model with reference to the accompanying drawing:
Referring to attached drawing, the rear end of secondary beam 2 is inserted into the preformed groove 10 of girder 1 through ox load plate 4, and 10 bottom surface of preformed groove is set
There is anti-shear steel plate 7, it can be by adding rubber sheet gasket, to play the role of shock insulation anti-attrition below the anti-shear steel plate 7.It is described reserved
Rectangular aperture sleeve 5 is equipped in slot 10, the ox load 4 rear end of plate is equipped with postive stop baffle 9, and the correspondence of postive stop baffle 9 is inserted into
In rectangular aperture sleeve 5.Referring to fig. 2, it since secondary beam 2 is symmetrically arranged in the two sides of girder 1 in pairs, accordingly has and symmetrically sets
The two rectangular aperture sleeves 5 set are connected through high-strength bolt 6 between them.The girder 1 and 2 top surface of secondary beam are equipped with cast-in-place folded
Close layer 8.
When assembling, the leading portion of ox load plate 4 is fixed in secondary beam 2 through peg 3 first, rectangular aperture sleeve 5 is placed at pre-
On the anti-shear steel plate 7 for staying 10 bottom surface of slot, opening direction opposite direction secondary beam 2, while being opened two symmetrical rectangles with high-strength bolt 6
Port sleeve 5 connects, and then by the corresponding inserting to rectangular aperture sleeve 5 of postive stop baffle 9 of ox load plate 4, all gaps are filled
Filled therewith.After completing above-mentioned installation, poured to form cast-in-place overlapping layers with cast-in-place concrete in girder 1 and secondary beam 2.
