Abstract
The utility model provides an assembled primary and secondary roof beam connection structure, its constitution includes: prefabricated girder and secondary beam, strengthening rib, bolt, cant chisei, girder include first girder and second girder, first girder along the embedding girder I -steel of secondary beam axis direction, and the secondary beam both ends are embedding to have a secondary beam I -steel, and the central line of second girder was stretched to the part that the second girder was imbedded to the girder I -steel, and the girder I -steel meets with the secondary beam I -steel and fixes through the connecting plate, girder I -steel at the second girder punches and passes the strengthening rib, a set of cant chisei of welding on the top flange of girder I -steel and secondary beam I -steel. The beneficial effects are that: the primary and secondary roof beam is the precast beam, can be prefabricated in the mill, reduce the site operation, the primary and secondary roof beam sets up the I -steel and connects through bolted connection and welded connection, and " doing " the formula that can realize is connected, and it is convenient to connect, and construction speed is fast.
Description
Technical field
This utility model relates to Architectural Equipment field, particularly relates to a kind of assembled primary-secondary beam attachment structure.
Background technology
The connector connected for prefabricated overlapping primary-secondary beam in prior art is a kind of hidden bracket, this hidden bracket is connected and composed by two pieces of parallel rectangular steel plates, rectangular steel plates two ends bottom welding cushion block, is also welded with the reinforcing bar extended downwardly from the outside of rectangular steel plates, and Bar Anchorage is in prefabricated overlapping secondary beam.Hidden bracket is as the connector of prefabricated overlapping primary-secondary beam, low with the bond strength of beam, anti-pulling ability；And reinforcing bar uses welding manner to be fixed on outside steel plate, there is certain hidden danger of quality.
In prior art, the attachment structure of primary-secondary beam is usually: set transverse concave groove in girder junction, and the end of secondary beam rides upon this groove of girder, or uses hidden bracket as primary-secondary beam connector, then uses concreting to form primary-secondary beam attachment structure.Set when groove makes precast main beam in lifting or transport in precast main beam be susceptible to fracture, the quality problems such as crack, pour bonding strength at rear primary and secondary beam nodes more weak.Hidden bracket is used to improve the bonding strength at primary and secondary beam nodes to a certain extent as the primary-secondary beam attachment structure of connector, but the structural strength still suffering from prefabricated overlapping primary-secondary beam junction is relatively low, anti-pulling ability, can not effectively prevent prefabricated overlapping time stress beam from concentrating produced shear crack, affect load performance and construction quality.
Utility model content
This utility model, for solving problems of the prior art, proposes a kind of assembled primary-secondary beam attachment structure.
The technical solution of the utility model is achieved in that
A kind of assembled primary-secondary beam attachment structure, its composition includes: prefabricated girder and secondary beam, reinforcement, bolt, peg, described girder includes the first girder and the second girder, described first girder is along described secondary beam axis direction embedding girder I-steel, described secondary beam two ends are embedding secondary beam I-steel, and the part of described girder I-steel described second girder of embedment extends through the centrage of described second girder, and described girder I-steel is connected with described secondary beam I-steel and fixed by connecting plate；Described girder I-steel at described second girder punches and passes described reinforcement, welds one group of peg at described girder I-steel with on the top flange of described secondary beam I-steel.
All there is string perforate described girder I-steel and described secondary beam I-steel joint, described connecting plate has two row bolts hole on being, the two described bolts hole of row are corresponding with the perforate of the perforate on the web of described girder I-steel and the web of described secondary beam I-steel respectively, and bolt is fixed after the perforate on described bolt hole and web.
The edge of a wing of the edge of a wing of described girder I-steel and described secondary beam I-steel is by being welded and fixed.
The beneficial effects of the utility model are: this utility model simple in construction, and primary-secondary beam is precast beam, can be prefabricated in engineering, reduce site operation;Primary-secondary beam arranges I-steel joint and is bolted and is welded to connect, and " doing " formula that can realize connects, and easy to connect, speed of application is fast.
