Description
Technical field
It the utility model is related to technical field of building construction, and in particular to a kind of prefabricated beam.
Background technology
With the development of modern architecture industry technology, assembled architecture turns into the focus of building trade.At present, implement both at home and abroad
Assembled architecture concrete structural system and steel structure system can be divided into according to the difference using material, and concrete body
System is divided into cast-in-place concrete structure again according to prefabricated rate is different（Partial component is prefabricated）And prefabricated concrete structure.Study carefully its development
Reason, wherein an important technology factor of guiding assembled architecture development is exactly precast concrete（That is PC components）Tear open
Set up meter separately.The fractionation of PC components is gradually developed into the fractionation of agent structure component by building enclosure or architectural concrete component.
In assembled architecture, method for splitting is Prefabricated superposed beam to horizontal member precast beam earlier, while is needed before precast beam in-site installation
Again formwork-support is set up, so as to cause assembled main structure construction process more, material has and manually puts into more and shadow
Ring the duration.
Utility model content
For solution, beam structure construction process is more in the prior art, and material has and manually put into more and the influence duration
Technical problem, the utility model provide a kind of prefabricated beam.
To achieve the above object, the technical solution adopted in the utility model is：A kind of prefabricated beam, its feature
It is：Including precast beam, cage bar, stirrup, main ribs include top additional bar at bearing, enter bearing lower rebar, be elongated
Reinforcing bar, bearing reinforcing bar is not entered；
Precast beam generally band chooses the beam channel structure type of ear, and middle part section is inverted T-shaped, and the top of precast beam is disposed with
Top additional bar and elongated reinforcing bar at bearing, wherein elongated reinforcing bar is evenly arranged in the corner of stirrup and enters pillar support, branch
Top additional bar is between elongated reinforcing bar at seat；
The lower disposed of precast beam has into bearing lower rebar and does not enter bearing reinforcing bar, wherein not entering the uniform cloth of bearing reinforcing bar
Be placed in the corner and centre position of stirrup, enter bearing lower rebar be located at precast beam bottom and two arrangement put.
The elongated reinforcing bar meets that the anchoring of reinforcing bar atlas bean column node requires into standoff length.
Top additional bar enters pillar support length at the bearing and length must meet reinforcing bar atlas beam branch in beam
The length legislations of seat upper longitudinal bar.
It is described enter bearing lower rebar enter pillar support length must meet reinforcing bar atlas bean column node anchoring require.
The clear spacing of each cage bar horizontal direction is in more than 25mm, and more than reinforcing bar maximum gauge.
Each cage bar up and down two layers of arrangement when, the clear spacing between each layer reinforcing bar is and maximum in reinforcing bar in more than 25mm
It is more than diameter.
The utility model is directly hung after transporting precast beams to scene using the vertical transport such as big machinery or live tower crane
Dress is in place, avoids setting up the waste of manpower, material tool that formwork-support brings etc. again, after component is in place at in-situ layer and bearing
Mounting portion stress cage bar, can be poured at bearing and cast-in-place layer concrete after acceptance(check), and constructing operation is simple, save template
The material such as installation tool and artificial input, while reinforcement installation amount is less at node bearing, and process is easy, be advantageous to accelerate the duration and
Greatly improve the impression quality of agent structure.
Brief description of the drawings
Fig. 1 is the utility model structure diagram.
Fig. 2 is Fig. 1 A-A profiles.
Fig. 3 is Fig. 1 B-B profiles.
In figure：1- precast beams, top additional bar at 2- bearings, 3- enter bearing lower rebar, the elongated reinforcing bars of 4-, and 5- does not enter
Bearing reinforcing bar, 6- stirrups.
Embodiment
The utility model is described in detail below in conjunction with the accompanying drawings, but the utility model is not limited to specific embodiment.
Embodiment 1
As shown in Figure 1-Figure 3, a kind of prefabricated beam, including precast beam 1, cage bar, stirrup 6, wherein cage bar bag
Top additional bar 2 at bearing is included, enters bearing lower rebar 3, elongated reinforcing bar 4, enter bearing reinforcing bar 5；
The generally band of precast beam 1 chooses the beam channel structure type of ear, and middle part is inverted T-shaped.Beam top is disposed with bearing
Locate top additional bar 2 and elongated reinforcing bar 4, wherein elongated reinforcing bar 4 is evenly arranged in the corner of stirrup 6 and enters pillar support, enter
Enter standoff length and meet that the anchoring of reinforcing bar atlas bean column node requires；Top additional bar 2 is between elongated reinforcing bar 4 at bearing,
Position is blocked into pillar support length and in beam（The length i.e. in beam）Reinforcing bar atlas beam support upper longitudinal bar must be met
Length legislations.Beam lower disposed has into bearing lower rebar 3 and does not enter bearing reinforcing bar 5, is evenly arranged wherein not entering bearing reinforcing bar 5
In the corner of stirrup 6 and centre position；Enter bearing lower rebar 3 be located at beam channel bottom and two arrangement put, into pillar support
