Description
Technical field
The present invention relates to engineering machinery, the supporting shelf bracket of a kind of No. 0 block of cantilever bridge.
Background technology
No. 0 block is from great, for work high above the ground, if safety smoothly completes, and is decided by the intensity of the mould bases of No. 0 block, deformation
And can stability meet safe handling requirement, especially as the bracket of load-bearing.Therefore No. 0 block rack form of reasonable selection is also
It it is the key of Cantilever Beam Construction success or failure.
The supporting form of No. 0 common block support has: consolidate formula bracket, hood type supporting etc. on console mode, pier shaft.Fall
Ground formula refers to that the supporting of support is located on earth's surface or on cushion cap, and ground to be processed by this scheme, compares foundation requirement
Strictly, it is necessary to have enough bearing capacities, settling amount should meet requirement, and differential settlement is very big to support security implication.Material, people
Work and mechanical appliances are big, and cost is high, expensive, and speed is slow, and high pier and soft soil foundation are inapplicable.
Consolidation formula bracket refers to pre-embedded steel slab or shaped steel etc. on pier shaft, and then support is welded on pre-embedded steel slab or shaped steel
On, load is through support transmission pre-embedded steel slab or shaped steel again on pier shaft, and this scheme pre-embedded steel slab or shaped steel need to cut off, clear up
Weldering spot, eliminating rust, be coated with antirust paint, smear high grade mortar etc., the work high above the ground time is long, and labour intensity is big, and operation work post is many, intersects and makees
Industry is many, interferes with each other big.During former weldering temperature welding, the intensity of pier shaft concrete can be greatly affected, even hardening crack pier shaft concrete.
Hood type supporting refers to drawing high intensity pull bar anchor ear on pier shaft, and anchor ear and pier shaft are linked to be entirety, utilizes and embraces
The frictional force of hoop and pier shaft is as supporting force.This scheme is applicable to the beam section that upper load is little, due to frictional force affect because of
Element is many, and during frictional force deficiency, potential safety hazard is big.
No. 0 block of continuous beam with high-pier have pier high, from the feature such as great, the selection of support should ensure that enough rigidity, intensity
And stability, the safety of load-bearing support body should be ensured, reach economic and practical effect again.
Summary of the invention
It is an object of the present invention to provide the supporting shelf bracket of a kind of No. 0 block of cantilever bridge, to overcome in above-mentioned prior art 0

Firmly.Two groups of bracing frames 10 strengthen steel seat 17 be respectively arranged at two ends with tie rod hole 21, thus available two ends are screwed
Pull bar and nut fix this two crossbeams 17, make the supporting shelf bracket of these bridge pier pier shaft 11 both sides form entirety.
Herein it should be understood that for the use adapting to product of the present invention, bridge pier pier shaft 11 above-mentioned needs
It is reserved with the preformed hole of a plurality of latch rod and a plurality of pull bar preformed hole in advance.Preformed hole uses and buries pvc pipe or steel pipe underground, buries
If pipe two ends block with the readily removable film removed, prevent concrete from entering in pipe.Bury effective reinforcing bar location underground, prevent positioning.
With reference to Fig. 1, in the preformed hole of the latch rod that latch rod only need to be inserted bridge pier pier shaft 11 by the present invention, horizontal stroke can be completed
Support system below beam 17, simple to operate.Load on supporting shelf bracket can be reached slotting by raker beam 13 by the present invention
Pin rod iron 14, then by latch rod iron 14 power transmission to the bridge pier completed, stress is simple, and power transmission is clear and definite.Due to the fact that and adopt
With unsettled, supporting shelf bracket is installed, it is to avoid the special requirement in console mode mounting bracket basic ring border over the ground in prior art.This
Invention avoids pre-embedded steel slab or shaped steel in prior art and need to cut off, clears up weldering spot, eliminate rust, be coated with antirust paint, smear high grade mortar
Etc. complex operations.The impact that when avoiding former welding, the intensity of pier shaft concrete can be caused by the welding of weldering temperature simultaneously.The present invention is on ground
Can process various accessory, in-site installation, mechanical one-shift is few, reduces amount of high-altitude operation, shortens the high-altitude application time.The present invention pacifies
Dress is convenient, and operation work post is less, reduces cross-operation and interferes with each other, alleviating personnel labor intensity.Mounting technique of the present invention is difficult
Spend little, common work post, it is not required to extraordinary work, optimizes the configuration of human resources.In sum, the effectively save one-tenth of the present invention
Basis, the efficiency that improves, safety are the most secure.
Above are only the detailed description of the invention of the present invention, but the design concept of the present invention is not limited thereto, all utilize this
Design carries out the change of unsubstantiality to the present invention, all should belong to the behavior invading scope.
