Abstract
A kind of Two bors d's oeuveres prestressing force overlapping girder, reinforced concrete part is poured with after including two rectangle prefabricated reinforced concrete beam bodies, the two group is at T-shaped or ∏ shape composite beam, it is characterized in that: the prefabricated reinforced concrete beam body is embedded with stirrup, stirrup stretches out beam body upper surface certain length, prefabricated reinforced concrete beam body lower part is longitudinally embedded with pretensioned prestressing steel strand wires, and reinforced concrete part top is poured after the composite beam and is longitudinally embedded with reinforcing bar.The beam prefabricated force request for being able to satisfy common stretching bed seat of the utility model, prefabricated components manufacturing cost are low.
Description
Technical field
The utility model relates to building structure field more particularly to a kind of pretensioned prestressing composite beams.
Background technique
Pretensioned prestressing precast beam generallys use long line method production, when joist steel twisted wire radical is more, conventional tensioning
Pedestal is unable to satisfy the pouring of antidumping and top pillar (pedestal plate), can be by a crossbeam point to meet manufacturing process requirement
Cheng Ergen production, while reducing the requirement to lifting machine.A kind of point two prefabricated, lifting rear integral cast-in-situ in place composite beams
It has not been reported.
Utility model content
The technical problem to be solved by the utility model is to overcome the deficiency of the above-mentioned prior art, a kind of technique letter is provided
Just point two prefabricated, lifting rear integral cast-in-situ in place composite beams.
According to a kind of Two bors d's oeuveres prestressing force overlapping girder provided by the utility model, including two rectangle prefabricated reinforced concrete beam bodies
Pour reinforced concrete part with after, the two group is at T-shaped or ∏ shape composite beam, it is characterized in that: the prefabricated reinforced concrete beam body is embedded with hoop
Muscle, stirrup stretch out beam body upper surface certain length, and prefabricated reinforced concrete beam body lower part is longitudinally embedded with pretensioned prestressing steel strand wires,
Reinforced concrete part top is poured after the composite beam is longitudinally embedded with reinforcing bar.
Also there is following attached technical characteristic according to a kind of Two bors d's oeuveres prestressing force overlapping girder provided by the utility model:
The top side of the prefabricated reinforced concrete beam body is equipped with several notches, is embedded with U-shaped hangs muscle in indentation, there concrete.
It is had the advantages that compared with prior art according to a kind of Two bors d's oeuveres prestressing force overlapping girder provided by the utility model
1, the beam prefabricated force request for being able to satisfy common stretching bed seat, prefabricated components manufacturing cost are low.
2, lifting is convenient, and stress performance is equal to the common beam of entirety.
Detailed description of the invention:
Fig. 1 is the arrangement of reinforcement elevation of the utility model
Fig. 2 is the utility model Two bors d's oeuveres composite beam sectional view
Fig. 3 is the prefabricated beam perspective view of the utility model
Specific embodiment:
Referring to Fig. 1 to Fig. 3, a kind of Two bors d's oeuveres prestressing force overlapping girder that the utility model provides, including two rectangles are prefabricated
Reinforced concrete beam body 1 and after pour reinforced concrete part 2, the two group is at T-shaped or ∏ shape composite beam.It is buried in the prefabricated reinforced concrete beam body 1
Equipped with stirrup 11, stirrup 11 stretches out beam body upper surface certain length, and it is pre- that 1 lower part of prefabricated reinforced concrete beam body is longitudinally embedded with pre-tensioning system
Prestress steel strand 12 pours 2 top of reinforced concrete part after the composite beam and is longitudinally embedded with reinforcing bar 21.It is overlapped using Two bors d's oeuveres prestressing force
Girder, first the prefabricated lesser single precast beam of height, is the beam prefabricated force request for being able to satisfy common stretching bed seat, prefabricated components
Manufacturing cost is low；Two bors d's oeuveres after lifting, after pour and be overlapped into big girder, stress performance is equal to an entirety commonly big girder.
Referring to Fig. 1 to Fig. 2, in above-described embodiment that the utility model provides, the top one of the prefabricated reinforced concrete beam body 1
Side is equipped with several notches 13, and indentation, there is embedded with U-shaped hangs muscle 14.Prefabricated reinforced concrete beam body top side be equipped with notch be in order to
Primary-secondary beam shelves secondary beam end when being coupled, accurate positioning, easy for installation.It is that secondary beam is put in order to prevent that indentation, there, which buries U-shaped hangs muscle,
It sets place periphery and locally generates crack.
Claims (2)
1. a kind of Two bors d's oeuveres prestressing force overlaps girder, including two rectangle prefabricated reinforced concrete beam bodies pour reinforced concrete part, the two with after
The at T-shaped or ∏ shape composite beam of group, it is characterized in that: the prefabricated reinforced concrete beam body is embedded with stirrup, stirrup stretches out beam body upper surface
Certain length, prefabricated reinforced concrete beam body lower part are longitudinally embedded with pretensioned prestressing steel strand wires, pour reinforced concrete after the composite beam
Part top is longitudinally embedded with reinforcing bar.
2. Two bors d's oeuveres prestressing force as described in claim 1 overlaps girder, it is characterized in that the top side of the prefabricated reinforced concrete beam body
Equipped with several notches, U-shaped hangs muscle is embedded in indentation, there concrete.
