Description

Two-sided composite beam and its construction method
Technical field:
The present invention relates to a kind of two-sided composite beam and its construction methods.
Background technique:
At this stage, country greatly develops housing industrialization, but in existing pre-cast building mode, precast beam is by beam length The limitation such as degree, production environment, transport and mounting condition.Cause beam segmentation prefabricated, beam main tendon is embedded in precast concrete, position It is fixed from rotation, causes traditional beam main tendon connection type that should not use, connection method is few, and connection is difficult, and quality of connection is not Easily guarantee, link position needs, which stay, sets post-cast strip, and complex procedures restrict housing industrialization development.
Summary of the invention:
The object of the present invention is to provide a kind of two-sided composite beam and its construction methods.
Above-mentioned purpose is realized by following technical scheme:
A kind of two-sided composite beam, composition includes: framework of steel reinforcement, precast slab, the framework of steel reinforcement vertical two Side pours the precast slab, and the framework of steel reinforcement includes girder rib, and one group is equipped in the girder rib Beam stirrup, beam stirrup two sides vertical edge described in one group are fixed with the girder rib, beam stirrup two sides vertical edge described in one group with One group of distributing bar is fixed, and beam stirrup foursquare arc position described in one group is installed with beam main tendon, the precast concrete respectively There is the section smoothly reduced on the inside of plate.
The two-sided composite beam is arranged in parallel between beam stirrup described in one group, and the beam stirrup is butt welding connection Closed circular either end be bent into the forms of 135 degree of crotches, the crotch forms closed circular or to form one long One is short U-shaped, and the two-sided composite beam is used for the precast concrete plate surface setting insulating layer of outdoor side or sets simultaneously Set insulating layer and decorative layer.
A kind of construction method of two-sided composite beam, this method comprises the following steps:
It is that position is actually used according to two-sided composite beam first, is that floor is pre- on two sides precast slab top or lower part Stay installation space, by the two-sided composite beam be used for outdoor side the described precast concrete plate surface setting insulating layer or Insulating layer and decorative layer is arranged simultaneously in person, after two-sided composite beam completes as requested, transports to construction site, reaches peace Dress condition, setting support, fixed bed die lift two-sided composite beam, adjust its position and absolute altitude, beam main tendon bound, to described The beam stirrup is bent into closed circular after the completion of beam main tendon binding, the beam main tendon is connected by butt welding, ties up item weldering It connects in succession, overlap the modes connection length such as connection and mechanical connection, after floor is installed, seal precast slab and bottom The positions such as template gap pours, vibrated concrete and conserves, completes the construction of two-sided composite beam.
The utility model has the advantages that
1. the present invention is a kind of two-sided composite beam, beam reinforcement cages are made of beam stirrup, distributing bar and girder rib, described Beam reinforcement cages two sides be precast slab, there is the section smoothly reduced, reduction on the inside of the precast slab Section afterwards does not influence the binding of beam main tendon, without installing two side template of beam when casting concrete, saves consumptive material, save the cost, It shortens the construction period.
Beam stirrup of the invention is that end is bent into the forms of 135 degree of crotches, and form that one is long and the other is short is U-shaped, described in two kinds Beam hooping structure form, it is U-shaped that beam stirrup is that one is long and the other is short, after the completion of beam main tendon binding, is bent into closed ring-type, energy Beam main tendon after enough making bending forming is formed directly into two-sided composite beam, saves the inconvenience bent again after binding.
Girder rib section of the invention is right angled triangle, a level right angle side and beam stirrup bottom short side and two sides Side forms statically determinate structure, and the girder rib section is triangle, and intensity can guarantee that beam reinforcement cages are stablized, and stacks and lifts Indeformable, due to the presence of girder rib, the statically determinate structure for forming two-sided overlapping beam reinforcement cages is unlikely to deform, can guarantee Product guarantees the beam section size after surviving in the stability of transport and hoisting process.
Insulating layer or same can be set in the precast concrete plate surface that two-sided composite beam of the invention is used for outdoor side When setting insulating layer and decorative layer, after two-sided composite beam completes, transport to construction site, mounting condition to be achieved, setting Support, fixed bed die, lifts two-sided composite beam, adjusts its position and absolute altitude, binds beam main tendon, beam main tendon by butt welding connection, The modes spreadings such as item is welded to connect, overlap joint is connected and is mechanically connected are tied up, after floor is installed, seal precast slab and bottom The positions such as portion's template gap pours, vibrated concrete and conserves, completes the construction of two-sided composite beam, can be realized and once survive, Reduce process.
The present invention solve the problems, such as cross beam and primary-secondary beam intersection can not precast assembly, at node after beam main tendon Binding guarantees node security.
It is cavity among two sides precast slab of the invention, beam main tendon can be worn after prefabricated components are installed Enter and bind, beam main tendon can utilize traditional reinforcement welding connection, overlap joint connection, straight screw sleeve connection, taper thread sleeve Connection squeezes the modes such as sleeve connection, and beam main tendon binding is convenient, and quality of connection is easily guaranteed that.
It is cast-in-place concrete inside two-sided composite beam of the invention, forms T-type structure, overall performance with plate cast-in-place concrete By force.
Two-sided composite beam of the invention, can be according to the Specific construction situation of two-sided composite beam, will be in precast slab Side lower part either upper design, can also be by the section smoothly reduced on the inside of precast slab at the section smoothly reduced It turns upside down placement, solve the problems, such as precast beam drop plate node and above returns girder connection processing difficulty.
