Description
Technical field
The present invention relates to the technical fields of construction, and in particular to a kind of assembled architecture primary and secondary joist steel connecting node knot
Structure.
Background technique
Primary and secondary beam connecting node is the important component part of assembled arthitecutral structure, and stabilization, the reliability of connecting node are
The key of structure design and construction.Assembled architecture primary-secondary beam connection at present mostly uses straight screw sleeve connection, pre-embedded steel slab bolt
In conjunction with connection.As 108999297 A of Chinese patent CN discloses a kind of novel fabricated primary and secondary beam connecting node and its connection
Method, disclosed in connection type be mainly at girder overlap joint secondary beam top two sides set two beam slots, secondary beam (is overlapped with girder
End) top surface set mounting groove, two beam groove height of girder and width are consistent with secondary beam, secondary beam insertion beam slot, pass through spiral shell
Bolt pre-fixes primary-secondary beam, then reinforces fixing by cast-in-place concrete.But at present primary and secondary beam connecting node poured after mostly using section and
On the one hand the form of construction work shelved needs to set up a large amount of supports and template sets up support and installation template when space is smaller
It is restricted；On the other hand pour after using and cause component partial there are weak location when mode is constructed, exist fracture, the matter in crack
Amount problem, and weaken the convenience of fabricated construction.When using form of construction work is shelved, the weakening of component partial section is larger,
Influence end shearing resistance.In addition, the patent of Patent No. CN2015206587423 discloses a kind of connecting node of primary-secondary beam,
The main technical schemes are design L shape bottom plate to connect girder and secondary beam, and by bolt locking, but the structure is mainly applied
On steel structure girder, rather than beams of concrete；In addition, the patent of Patent No. CN2017204900573 discloses a kind of assembled
Primary-secondary beam connecting joint structure, main technical schemes are as follows: the prefabricated bracket set on the beam body side of precast main beam is set to prefabricated
The fitting groove of the end of secondary beam, prefabricated bracket include web, and bracket pilot hole is offered on web, are opened up on prefabricated secondary beam
There is secondary beam pilot hole, which aligns with the secondary beam pilot hole is arranged and is connected using connector (bolt)；The technology
The primary-secondary beam connecting joint structure of scheme is to set to shelve pre-buried T steel plate, the connection of bolt anchor, and this mode node shearing resistance is low；Coagulation
The aperture that native bolt hole is opened need to be larger, and otherwise to not upper steel plate hole, the big error deviation for indicating installation in aperture is big；It is supported by web
Secondary beam, after secondary beam is placed, the bit errors of secondary beam pilot hole and bracket pilot hole are high.
Summary of the invention
The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a kind of no support, wet-less operation,
The assembled architecture primary and secondary joist steel connecting joint structure that intensity is high, rigidity is high, firm, installation is simple and fast, time saving and energy saving.
The technical solution used in the present invention is:
A kind of assembled architecture primary and secondary joist steel connecting joint structure, including be set to precast main beam side pre-buried bracket and
Set on the pre-buried push pedal of the end sides of prefabricated secondary beam, the pre-buried bracket includes that wing plate frame and two pieces mutually hang down with the wing plate frame
Straight hanging plate, by setting bottom plate integrally connected between the bottom of two pieces of hanging plates, the wing plate frame is embedded in described prefabricated in advance
In girder, if being vertically installed with bolt stem on the pre-buried push pedal, the both ends of the bolt are piercing in the prefabricated secondary beam, institute
It states and is provided with and adaptation bayonet corresponding with the end of the bolt on hanging plate.
In the above scheme, primary-secondary beam separately designs built-in fitting, and the bolt on prefabricated secondary beam can ride upon precast main beam
Pre-buried bracket bayonet on, formation is bonded structure, install it is simple and fast, it is time saving and energy saving, then enable precast main beam and pre-
Secondary beam processed is bonded.Wing plate frame is embedded in precast main beam in advance, and pre-buried push pedal is arranged in prefabricated secondary beam, guarantees that the connection structure is strong
Degree is high, rigidity is high；Bottom plate can play the weight for centainly carrying prefabricated secondary beam；It designs bottom plate and connects two pieces of hanging plates, so that entirely
Intensity, the rigidity of pre-buried bracket are more increased, while this assembled architecture primary and secondary joist steel connecting joint structure also has without support, nothing
The effect of wet construction.
Further, the end of the bolt is provided with nut, and the outer diameter of the nut is greater than the width of the bayonet.Institute
It states and is provided with plain cushion meson between nut and the hanging plate.
In the above scheme, precast main beam can be enabled to connect with prefabricated secondary beam with clamping screw using nut more firm.
Further, the side of the end of the prefabricated secondary beam is provided with necking slot, and the pre-buried push pedal is arranged described
On the side of necking slot, the lateral surface of the pre-buried push pedal is concordant with the lateral surface of the necking slot, the end of the prefabricated secondary beam
Portion is inserted between two pieces of hanging plates.
In the above scheme, between prefabricated secondary beam insertion hanging plate, contraposition is accurate, and bottom plate, which can play, centainly to be carried prefabricated time
The weight of beam acts on.
Further, there are two the bayonets for setting on the hanging plate, positioned at the height and position of the bayonet in the outer part
Lower than the height and position for being located at the bayonet in the inner part.Each corresponding two bolts of the bayonet, two bolts are along high
Spend direction alignment setting.
In the above scheme, multiple bayonets and not concordant are designed, it is ensured that bolt is cooperated to all-the-time stable on bayonet.
Further, the pre-buried push pedal in the prefabricated secondary beam has two pieces, and two pieces of the bolt-through is described pre-buried
Push pedal.
In the above scheme, designing two pieces of pre-buried push pedals can play the role of balancing prefabricated secondary beam weight, spiral shell for bolt
Bolt is connected with pre-buried push pedal, guarantees integral strength.
The invention has the benefit that firstly, connecting node intensity is high, prefabricated secondary beam self weight and thereon can be undertaken completely
Portion's load exempts to support, save the cost, reduces workload；Position error is small, restraining force is big, and rigidity is big, and displacement is small, and installation is accurate,
Be conducive to improve installation quality；Secondly, structure is simple, operation is simple, one end one man operation is completed, and labor intensity is reduced, and is promoted
Working efficiency；Again, section is poured, it can be achieved that wet-less operation after connecting indwelling with the bolt on pre-buried push pedal using pre-buried bracket
Deng.
