Description
Technical field
The present invention relates to maintenance engineering fields, and in particular to a kind of hanger platform of T beams maintenance and reinforcement.
Background technology
T beam bridges refer to RC T tee section simply supported beam.Since economical rationality is designed in section, coagulation is taken full advantage of
The anti-pressure ability of soil, farthest reduces the area of concrete in tension zone so that and the weight of tee girder structure is mitigated,
The method that construction technology majority uses prefabrication and assembly construction, the method that integral cast-in-situ also can be used have and lift light-weight, construction letter
Single, the few feature of used device, in China, existing highway Short/Medium Span Bridge is widely used.But T beams are long-term in overloaded vehicle
Under effect, T beams generate fatigue rupture, bending bearing capacity decline, across on endosternum and bottom plate there are Vertical Cracks;Due to coagulation
Soil is shunk or shear-carrying capacity deficiency generates end inclined crack;Since T beams are precast assembly structure, diaphragm plate is adopted between each T beams
It is attached with the mode that lower part junction steel plate welds, this construction has the shortcomings that its is geneogenous, i.e., diaphragm plate lower part connects
Be under Vehicle Load, outsourcing mortar is easily cracking, it is damaged, peel off, lead to that junction steel plate is exposed, corrosion, weldering
Easy stress concentration at point, fatigue rupture, until desoldering makes each T beam stress situation deteriorate, become to weaken lateral ties between T beams
It is bordering on single-beam stress.
It needs to repair reinforcing to T beams regarding to the issue above, carbon fibre material stickup generally is carried out to T beams, steel plate glues
The maintenance activities such as patch, the conventional dimension at present usually using routine maintenances platforms such as tool car, moving hanging basket and Hanging Baskets, but at present
