Build of the remote past, design load grade is relatively low, and in addition by operation for many years, load carrying capacity of bridge and safety stock can not
Meets the needs of Current Traffic, increasing arch bridge needs to carry out reinforcing punishment, to improve load carrying capacity of bridge and safety
Deposit.
At present, the reinforcing of arch bridge spandrel arch circle is reinforced using view picture set arch mostly, still, covers what arch was reinforced using view picture
Following defect be present in mode：
1st, view picture cased arch construction section is big, bricklaying quantity is big, damage of the former bridge drilling to bridge is big, difficulty of construction is big；
2nd, the increased dead load of view picture set arch is larger, and the materials'use amount of construction view picture set arch is big, and construction cost is high.
Utility model content
For in the prior art the defects of, the utility model provides a kind of ruggedized construction of arch bridge spandrel arch circle, is improving
On the basis of arch bridge bearing capacity and safety in utilization, realize that lightweight is reinforced, and reach reduction bricklaying quantity, reduce to bridge
Damage, reduce difficulty of construction and reduce the purpose of construction cost.
Technical scheme provided by the utility model is：A kind of ruggedized construction of arch bridge spandrel arch circle, including spandrel arch circle body,
The both ends of the spandrel arch circle body are equipped with support wall, and two knee wall bodies side close to each other is equipped with multiple bottoms
Seat, is equipped with longitudinal arch rib on the two support walls between two bases that are oppositely arranged, all longitudinal arch ribs it
Between be provided with an at least crossbeam；
Between longitudinal arch rib and the crossbeam and the spandrel arch circle body and support wall and the base
Between be equipped with more reinforcing pull rods, be equipped with longitudinal arch rib, the crossbeam and the base and be connected with the reinforcing pull rod
Bar frame.
As an improvement the every reinforcing pull rod is big positioned at the support wall or the intrinsic depth of spandrel arch circle
In or equal to 10 times of the reinforcing pull rod diameter itself.
As a further improvement, the reinforcing pull rod is vertically arranged with the support wall or the spandrel arch circle body.
As further improve between the reinforcing pull rod and the spandrel arch circle body, the reinforcing pull rod and the support
Anchoring adhesive is equipped between wall.
Improved as further, the base, longitudinal arch rib and the crossbeam by C30-C50 concrete
Pour and form.
As improvement further, the bar frame welds together with the reinforcing pull rod.
By adopting the above-described technical solution, a kind of ruggedized construction of arch bridge spandrel arch circle provided by the utility model has
Beneficial effect is as follows：
Because two knee wall bodies side close to each other is equipped with multiple bases, two bottoms being oppositely arranged on two support walls
Longitudinal arch rib is equipped between seat, an at least crossbeam, longitudinal arch rib and crossbeam and spandrel arch circle are provided between all longitudinal arch ribs
Between body and support wall and base between be equipped with more reinforcing pull rods, be equipped with longitudinal arch rib, crossbeam and base with
The connected bar frame of reinforcing pull rod, based on said structure, the ruggedized construction of the arch bridge spandrel arch circle is in use, by interrelated
Base, longitudinal arch rib and crossbeam spandrel arch circle body is supported, and due to the presence of reinforcing pull rod, and then make spandrel arch circle body
Integral, the common stress with base, longitudinal arch rib and crossbeam shape, the mesh for improving arch bridge bearing capacity and safety stock is reached
, compared with the reinforcing mode of traditional view picture set arch, realize that lightweight is reinforced, greatly reduce construction section, bricklaying quantity, drop
Low difficulty of construction, save the dosage of material, reduce construction costs, and the damage to arch bridge in itself is small；Meanwhile effectively
Reduce dead load caused by the later stage, there is larger engineering application value；In addition, this is simple in construction, own wt is light, peace is used
Quan Xinggao.
Due to reinforcing pull rod positioned at support wall or the intrinsic depth of spandrel arch circle more than or equal to reinforcing pull rod diameter itself
10 times, so as to improve reinforcing pull rod and spandrel arch circle body or the connection reliability of support wall；Meanwhile be advantageous to improve spandrel arch circle
Body forms integrally-built service life with base, longitudinal arch rib and crossbeam.
Because reinforcing pull rod and support wall or spandrel arch circle body are vertically arranged, so as to more reasonable by the structure stress,
Service life is longer.
Due to being equipped with anchoring adhesive between reinforcing pull rod and spandrel arch circle body, between reinforcing pull rod and support wall, so as to pass through
Anchoring adhesive further increases reinforcing pull rod and spandrel arch circle body and the connection reliability of support wall.
Because base, longitudinal arch rib and crossbeam form by C30-C50 concreting, so as to ensure that base, indulge
To the structural strength of arch rib and crossbeam, laid a good foundation to improve bearing capacity.
Because bar frame and reinforcing pull rod weld together, so as to ensure that the stationarity of bar frame, and then ensure to pour
When building concrete, bar frame will not be shifted over.
