Description
Technical field
The utility model is related to bridge construction field of engineering technology, and in particular to a kind of assembled simple supported box beam end floor beam structure
It makes.
Background technology
Assembled simple supported box beam is a kind of common bridge type in highway bridge, because box beam torsional rigidity is big, holistic resistant behavior
It is good, and quick construction, it is simple for process, just more and more applied.Counter-force is concentrated in order to undertake beam-ends torque and bearing, is needed
End floor beam is set in beam-ends.
The end floor beam used at present uses the continuous mode of indoor and outdoor, indoor and outdoor that end floor beam is arranged simultaneously, and thickness is identical,
General requirement is integral prefabricated with girder.The problem is that：Box section is silent cross section type, when prefabricated box -beam, is not only needed
External mold is set, and interior also needs to setting internal model, and precast beam both ends are designed with end floor beam, confined air is formed after concreting
Between, indoor internal model can not remove.Unit in charge of construction, which considered to slot in box beam top plate, takes out template, extremely difficult, top plate slot of constructing
Mouth Quality of recovery is poor, influences structure stress.Therefore it needs to study a kind of assembled simple supported box beam easy for construction, safe and reliable
End floor beam constructs.
Invention content
The purpose of this utility model is to provide a kind of assembled simple supported box beam end floor beam construction, overcomes lacking for the prior art
It falls into.
Technical solution used by the utility model is：
A kind of assembled simple supported box beam end floor beam construction, it is characterised in that：
Including box beam, box beam is made of the web of the top plate on top, the bottom plate of lower part and both sides, and web outside is provided with cross
To vertical prefabricated end floor beam；
Bulkhead in laterally vertical case is provided in box beam.
The bottom plate of box beam uniformly thickeies from inside to outside, enables in case that cross section gradually tapers up from inside to outside.
It is provided on box beam top plate in case on the outside of bulkhead and reserves notch for carrying out the secondary beam-ends top plate poured.
Prefabricated end floor beam side and top plate are coplanar vertically.
Prefabricated end floor beam bottom surface is higher than bottom plate.
Box beam and the forming of prefabricated end floor beam integral concreting.
Bulkhead is fixed on by mortar in case in case.
The utility model has the following advantages：
In the utility model, end floor beam is provided only on the outside of box beam, prefabricated crossbeam is not provided in chamber, only in box girder inner formwork
It is secondary to pour bulkhead concrete after removing.End floor beam and box beam are prefabricated simultaneously on the outside of box beam, indoor not prefabricated end floor beam, for sky
The heart constructs.The upper and lower edge main reinforcement of end floor beam is separately positioned on box beam top, in bottom plate, does not interfere with the setting of box girder inner formwork.In box beam
Top plate setting length on the outside of end floor beam upper limb main reinforcement（Laterally）80cm, it is wide（Along bridge to）The reserved notch of 15cm or so, so as to
Pour second stage concrete, vertically and horizontally reinforcing bar must not block top plate at notch.Bulkhead is individually prefabricated, after box girder inner formwork removing,
Bulkhead is fixed into position shown in Fig. 2 with mortar, and after end mould is arranged in beam-ends, reserve notch 1 from beam-ends top plate from pour
Bulkhead concrete.This end floor beam scheme facilitates prefabricated box girder inner formwork to remove, and accelerates construction progress, while being conducive to pouring for end floor beam
Build quality, it is ensured that the stress safety in later stage.
Description of the drawings
Fig. 1 is prefabricated case beam end floor beam perspective view.
Fig. 2 is prefabricated case beam end floor beam longitudinal sectional drawing.
Fig. 3 is prefabricated case beam end floor beam transverse cross-sectional view.
In figure, 1- beam-ends top plates reserve notch；Bulkhead in 2- casees；The prefabricated end floor beams of 3-, 4- are poured for bis- times.
Specific implementation mode
The utility model is described in detail With reference to embodiment.
The utility model is related to a kind of assembled simple supported box beam end floor beam construction, including box beam, the bottom plate of box beam is certainly introversive
It is outer uniformly to thicken, enable in case that cross section gradually tapers up from inside to outside.Box beam is by the top plate on top, the abdomen of the bottom plate of lower part and both sides
Board group is at web outside is provided with laterally vertical prefabricated end floor beam.Box beam and the forming of prefabricated end floor beam integral concreting.In advance
End floor beam side processed and top plate are coplanar vertically, and bottom surface is higher than bottom plate.
Bulkhead in laterally vertical case is provided in box beam, bulkhead is fixed on by mortar in case in case.
It is provided on box beam top plate in case on the outside of bulkhead and reserves notch for carrying out the secondary beam-ends top plate poured.
When construction：
1）Assembling reinforcement sets inner and outer template, prefabricated case beam and end floor beam, pre- at crossbeam upper limb main reinforcement in top plate
Beam-ends top plate is stayed to reserve notch 1；
2）Bulkhead 2 in precast box.
3）External mold is removed, internal model is removed from box beam both ends.
4）Bulkhead in case 2 is arranged in chamber, and mortar blocks gap.
5）Beam-ends end mould is set.
6）End socket concrete and reserved notch concrete are poured from reserving notch 1 from beam-ends top plate, pays attention to vibration compacting.
7）After concrete reaches design strength, end mould is removed, precast beam construction finishes.
In the utility model, end floor beam is provided only on the outside of box beam, prefabricated crossbeam is not provided in chamber, only in box girder inner formwork
It is secondary to pour bulkhead concrete after removing.End floor beam and box beam are prefabricated simultaneously on the outside of box beam, indoor not prefabricated end floor beam, for sky
The heart constructs.The upper and lower edge main reinforcement of end floor beam is separately positioned on box beam top, in bottom plate, does not interfere with the setting of box girder inner formwork.In box beam
Top plate setting length on the outside of end floor beam upper limb main reinforcement（Laterally）80cm, it is wide（Along bridge to）The reserved notch of 15cm or so, so as to
Pour second stage concrete, vertically and horizontally reinforcing bar must not block top plate at notch.Bulkhead is individually prefabricated, after box girder inner formwork removing,
Bulkhead is fixed with mortar, and after end mould is arranged in beam-ends, reserve notch 1 from beam-ends top plate from pour bulkhead concrete.This
End floor beam scheme facilitates prefabricated box girder inner formwork to remove, and accelerates construction progress, while being conducive to the pouring quality of end floor beam, it is ensured that after
The stress safety of phase.
The content of the utility model is not limited to cited by embodiment, and those of ordinary skill in the art are new by reading this practicality
Type specification and to any equivalent transformation that technical solutions of the utility model are taken, be the claim institute of the utility model
Cover.
