Abstract
Continuous steel structure bridge installation temporary support, sandbox and bearing including flexible connection.Supporting surface opens up fluted, and the covering of net partition is fixed on above groove.Spin is rollably fixed between groove and net partition, and the top surface exposure of spin is in outside the network interface of net partition.The utility model replaces the face contact of original temporary support bearing using Multi-contact by the way that rotatable spin is arranged in supporting groove, reduces the frictional force between bearing support and box beam bottom plate.Further, by the further frictional force of the rolling of spin, to improve the support performance and security performance of support.
Description
Technical field
The utility model relates to continuous steel structure bridge site operation technical field more particularly to a kind of continuous steel structural bridges
Temporary support is used in beam installation.
Background technique
Steel box-girder span is big, simply connected weight is big, and construction is carried out using fragment production in field, live segmentation, branch mailbox body, wing plate
Assembly, must be arranged temporary rest pier when assembled and support sets up prefabricated case beam etc..Complete wet joint, wet hinge seam, hogging moment tensioning
And after the processes such as slip casting, temporary support is removed, completes system transform.Steel structure bridge expands with heat and contract with cold in the construction process,
Lead to beam body change in displacement, to generate horizontal thrust to falsework.Existing sandbox formula temporary support is by sandbox and common branch
Composition is held, supporting steel plate belongs to steel-steel with steel structure bridge base plate contact surface and contacts, and frictional force is larger, and beam body displacement generates
Horizontal thrust seriously affects the support performance and security performance of bracket.
Utility model content
The utility model provides a kind of continuous steel structure bridge installation temporary support, to solve the above-mentioned prior art not
Foot.By the way that rotatable spin is arranged in supporting groove, the face contact of original temporary support bearing is replaced using Multi-contact,
Reduce the frictional force between bearing support and box beam bottom plate.Further, by the further frictional force of the rolling of spin, to improve
The support performance and security performance of support.
In order to realize the purpose of this utility model, the following technology of proposed adoption：
Continuous steel structure bridge installation temporary support, sandbox and bearing including flexible connection, which is characterized in that bearing
Surface opens up fluted, and the covering of net partition is fixed on above groove, and spin is rollably fixed between groove and net partition,
The top surface exposure of spin is in outside the network interface of net partition.
Further, polytetrafluorethylecoatings coatings are equipped at groove surfaces.
Further, net partition uses polyfluortetraethylene plate, and activity is fixed at bearing.
Further, spin uses high strength steel material.
The utility model has the beneficial effects that：
1, the utility model is replaced original interim by the way that rotatable spin is arranged in supporting groove using Multi-contact
The face contact of bearing support reduces the frictional force between bearing support and box beam bottom plate.
2, the utility model passes through the further frictional force of rolling of spin, to improve support performance and the safety of support
Energy.
Detailed description of the invention
Fig. 1 shows the utility model structure diagram.
Fig. 2 shows the overlooking structure diagrams supported in an embodiment of the utility model.
Specific embodiment
As shown in Figure 1, continuous steel structure bridge installation temporary support, sandbox 10 and bearing 20 including flexible connection.
Sandbox 10 is set at the top of temporary rest pier, and bearing 20 is set to 10 top of sandbox, is supported and is set to below steel box-girder bottom plate.
It supports 20 surfaces and opens up fluted 1,1 top of groove is fixed in the covering of net partition 2, and spin 3 is rollably fixed on
Between groove 1 and net partition 2, the top surface exposure of spin 3 is in outside the network interface 21 of net partition 2.As shown in Fig. 2, in an embodiment
In, the network interface 21 of net partition 2 is in nine grids shape, and 9 spin 3 are set in groove 1.Each spin 3 is independently divided by net partition 2,
It freely rolls, top top of the exposure except net partition 2 is located at below steel box-girder bottom plate.
Spin 3 uses high strength steel material.Number, the diameter of determining spin 3 are required according to the operation of the steel box-girder of erection
And material, under the premise of the compressive resistance for guaranteeing single spin 3, the number of spin is controlled, to reduce bearing and steel box-girder bottom plate
Contact site, be conducive to reduce frictional force, guarantee improve support support performance and security performance.
Polytetrafluorethylecoatings coatings 11 are equipped at 1 surface of groove.Be conducive to reduce frictional force when spin 3 rolls.
Net partition 2 uses polyfluortetraethylene plate, and activity is fixed at bearing 20.It can be carried out when spin 3 is worn fast
Speed replacement.If failing the spin 3 for replacing abrasion in time, using the coefficient of friction of the net partition 2 of polyfluortetraethylene plate production itself
Also smaller, it is contacted compared with original bearing with steel box-girder Bottom Board Steel-steel, is conducive to the friction reduced between bearing support and box beam bottom plate
Power.
