Description
Technical field
This utility model belongs to field of bridge construction, is specifically related to a kind of Sarasota construction removable support.
Background technology
The most domestic carry out Sarasota construction frequently with overmolded technique and mould crawling process.Wherein over-form construction is above sections rope
Tower top joint template is as fixed knot and load part, and the template installing sections dismounting is constructed, and need to additionally set up scaffold
As operation platform；Creeping formwork is made up of jumping formwork, climbing frame and climbing equipment, is watering sections pre-buried track shear key, edge
The construction of track hydraulic lifting section by section, the external scaffolding in work progress can be saved at scaffold cradle in the template climbed.
Current domestic conventional Sarasota construction auxiliary stand has scaffold, creeping formwork support.Scaffold is to use steel pipe, foot hands
Plates etc. are successively set up and are formed, due to the restriction of scaffolding height, if conversion platform segmented-erection and dismounting need to be used when high tower,
Work high above the ground governing factor is many, and construction safety risk is big.Creeping formwork support is using hydraulic climbing shuttering as support, same with jumping formwork
Step promotes, if but the Sarasota changeable for cross section, track is pre-buried, installation accuracy is poor, and difficulty of construction is big.
It is oblique that the Chinese patent of Publication No. CN 103898836 A discloses a kind of cable-stayed bridge H type Sarasota height entablature steel
Lower limb prestress stent construction method, for field of bridge construction, it uses steel battered leg bracket and bow member to crossbeam of constructing, it is to avoid
In prior art, high trestle method is constructed the installation of a large amount of steel pipe supports and dismounting, when decreasing Sarasota construction built-in fitting installation and
Later stage patch work, reduces overhead welding workload and material, greatly reduces work high above the ground risk, has also evaded high simultaneously
Decrement reserved by frame and pre-buried calf support camber arranges the problems such as difficulty；Steel battered leg bracket stress is clear and definite, and upper node will be perpendicular
Passing to Sarasota to load, on lower node, the oblique horizontally outward component exerted oneself is executed in advance by prestress wire at inter-tie
The prestressing force added is offset, and on lower node, the oblique vertical force component exerted oneself is born by Sarasota.Additionally, Sarasota and the asynchronous construction of crossbeam,
Avoid the crossbeam side construction template of Sarasota and the high-altitude dismantling of climbing frame and installation, reduce security risk, shorten the duration.But
It is that above-mentioned construction method is only applicable to cable-stayed bridge H type Sarasota, and the Sarasota for other cross sectional shapes is constructed and inapplicable.
Summary of the invention
Defect that the purpose of this utility model is contemplated to overcome above-mentioned prior art to exist and provide a kind of and simplify construction
Process, the Sarasota construction removable support of reduction construction risk.
