Soil paste envelope.But this mode has the following deficiencies: that the concrete grout envelope service life is shorter, generates stress and concentrates and part easily occurs and breaks
Bad, overall mechanical properties are poor；And installation period is longer；
(4) it is respectively provided with jointing on girder or secondary beam, in fitting end pre-embedded steel slab, opens up spiral shell on the steel plate of side
Bolt mounting hole is bolted between steel plate, and twists bolt by mounting hole.But this mode has the following deficiencies: connection
Structure is complicated, at high cost, and it is prefabricated when construction it is complicated, production is inconvenient.
Utility model content
A kind of short time limit is provided the purpose of the utility model is to overcome the above-mentioned insufficient of the prior art, it is time saving and energy saving, at
The connection structure of this low girder and secondary beam.
The technical solution of the utility model is: a kind of connection structure of girder and secondary beam, and spiral shell seat is preset on the secondary beam, main
Swivel nut is preset on beam, girder passes through swivel nut, spiral shell seat by bolt and is fixedly connected with secondary beam.
Above scheme has the advantage that by the way that swivel nut and spiral shell seat is prefabricated on beam, 100% prefabrication of realization is live
Bolt only need to be installed, greatly shorten the duration, reduce manpower and installation cost, it is time saving and energy saving.
Further, the girder and secondary beam are prefabricated beam body, i.e. shop prefabricated module beam, to simplify installation, are improved
Work efficiency.
Preferably, the girder and secondary beam are made of core plate, core plate include first panel, second panel and be set to two sides
Laminboard layer between plate.
Further, the swivel nut is welded between first panel and second panel.
Further, core plate is surrounded by frame, and the spiral shell seat is welded on frame.
Further, pass through soldering or electric resistance welding connection between the laminboard layer and two panels.
Further, the laminboard layer includes several hollow pipes or corrugated sheet between two panels.Hollow pipe is cut
Face shape can be round, ellipse or the side N shape, N >=3 are also possible to other special pipes.Wherein, hollow pipe is equipped with flange,
Flange is the contact surface on hollow pipe, for being connect with panel, to increase the contact area between hollow pipe and panel, into
And improve bonding strength.
The utility model has the beneficial effects that
(1) by the way that swivel nut and spiral shell seat is prefabricated on beam, 100% prefabrication of realization, scene only need to install bolt, significantly
It shortens the construction period, reduces manpower and installation cost, it is time saving and energy saving；And simple structure when prefabricated, it is easy to make；
(2) when girder and secondary beam are made of core plate, weight is extremely light, and rigidity is high, and when lifting is time saving and energy saving, after installation
Stable structure, after core plate, swivel nut, spiral shell seat and bolt combine, overall mechanical properties are good；
(3) when girder and secondary beam are made of stainless steel core plate, the one side service life is close to permanently；On the other hand, stainless
The great toughness of steel can eliminate earthquake, earth subsidence and fatigue aging and threaten；And the structural behaviour of stainless steel can be detected, i.e., by
After being influenced to environment, service life, on-call maintenance and replacement can be predicted and be calculated, safety coefficient is greatly improved；
(4) the shop prefabricated module plate body for presetting swivel nut and spiral shell seat also acts as column and plate for building, as column and beam it
Between, between column and column, between Liang Yuliang, between beam and plate, between column and plate, this connection structure can be used between plate and plate
It is attached, it is applied widely.
