Description
Technical field
The utility model relates to a kind of large-tonnage box beam and sets up temporary support.
Background technology
The freely-supported of large-scale whole hole prestressed concrete box girder sets up, particularly the case beam more than the kiloton is when setting a roof beam in place, the case beam at first falls to being placed on to be preset on the temporary support at bridge pier top, form system of simple supporting, carry out the wet seam construction of bridge then, after wait to wet joint concrete intensity and prestress system reach requirement, by reducing the temporary support height, the case beam is fallen to being placed on the formal bridge pad, form continuous system.At present domesticly be used for the temporary support that the prefabricated whole opening box girder of large-tonnage sets up and adopt the sulphur-bonded mortar bearing more, but on the beam that adopts the advanced person, transport beam, during the fortune frame technology of setting a roof beam in place on the beam, require temporary support not only to need to bear monolithic precast beam weight, also need to satisfy Beam transportation vehicle and carry the load that beam walking and bridge formation frame are established the case beam, especially in supported behind the bridge formation machine on frame case beam, the bridge formation machine moves beam when waiting to set a roof beam in place the position, hole, temporary support bears peak load and can reach more than 1000 tons, cause sulphur-bonded mortar temporary support volume big, weight is bigger, it is not high that prefabricated case beam sets up precision, transportation and artificial the installation, remove difficulty, and the sulphur-bonded mortar bearing is disposable bearing, can not has enough to meet the need use in the work progress, not only cause input cost higher, also influence very much the construction period.Sulphur-bonded mortar temporary support sulphur-bonded mortar fusing risk is bigger, occur the resistance wire fracture easily, phenomenons such as the incomplete fusing of mortar can discharge a large amount of heats in fusing temporary support process, very easily cause pier shaft or beam body concrete piece cracking, consequence is very serious.The sulphur-bonded mortar slurries of sulphur-bonded mortar temporary support pollute SO to pier shaft
2The gaseous contamination environment damages human body.
The utility model content
Goal of the invention of the present utility model is: provide that a kind of supporting capacity is strong, the large-tonnage box beam of use repeatedly, non-environmental-pollution, carrying convenient disassembly sets up temporary support.
A kind of large-tonnage box beam sets up temporary support, it is characterized in that: comprise the steel sand top bearing that is arranged on the concrete pad, on the bearing of steel sand top laminated rubber bearing is set; Described steel sand top bearing is assembled by metal inner cylinder body, metal outer cylinder body, inner cylinder body place in the outer cylinder body and and outer cylinder body between constitute the sand storehouse, the placement steel sand sand storehouse in; This inner cylinder body comprises a top the be connected inner casing of head plate of upper plate, bottom that is connected; Outer cylinder body is made up of the outer shell of band base plate, and the outer shell bottom is provided with rushes down sand hole and sand hole obstruction; The outer wall of inner casing and the inwall of outer shell are complementary; Be provided with the securing member of removable location between the end face of inner cylinder body and the end face of outer cylinder body.
Described inner casing the inside comprises that also upper end and the upper plate lower end that is connected is supported on stiffener on the head plate.
Described stiffener is a cross-stiffened plate, and its upper end is connected with the upper plate fillet weld; Inner casing is connected with the upper plate groove welding, adopts fillet weld to be connected with head plate; Outer shell adopts fillet weld to be connected with lower shoe.
The described sand hole inwall that rushes down is opened the silk mouth, and obstruction is a bolt; The securing member of described removable location is the monolithic pull bar, and the one end passes the upper junction plate of upper plate, and the other end passes the lower connecting plate of base plate and uses bolton.
Described concrete pad label C40, length and width are of a size of 700 * 700mm; Laminated rubber bearing is 600 * 600 bridge laminated rubber bearings; Upper plate adopts 600 * 600 * 30mm Q345 steel plate, and inner casing adopts φ 480 * 20mm Q345 seamless steel pipe, and head plate adopts φ 520 * 20mm steel plate, and cross-stiffened plate adopts the 20mm steel plate, and outer casing wall adopts φ 530 * 25mm Q345 seamless steel pipe to make.
Adopt the large-tonnage box beam of above structure to set up temporary support, the concrete pad that the bottom is provided with, the overall height that is used for regulating bearing can reduce the deadweight on steel sand top; Laminated rubber bearing is in good stress in the time of cushioning the impact load when setting a roof beam in place and guarantee case beam freely-supported operating mode.With concrete pad coarse adjustment absolute altitude, accurately adjust the temporary support absolute altitude by in the sand storehouse on steel sand top, injecting steel sand again, be issued to sand top working depth at no-load condition, satisfy the linear design of bridge, guaranteed the construction quality of setting a roof beam in place, under heavily loaded situation, utilized steel sand pressure to be passed to lower shoe as pressure transmission medium.Steel sand flows out reduction temporary support height from rushing down sand hole under pressure, cause upper plate to break away from pressure-bearing surface and reach the unloading purpose,, make temporary support break away from the soffit with this height that reduces temporary support, bridge is fallen on the formal bearing, finishes the system conversion of bridge.
When installing with the dismounting temporary support, only need 2～3 people just can finish by small machine, do not need big machinery on bridge, to construct, guaranteed construction safety.And it is the steel sand of temporary support pushes up and steel sand can use repeatedly, and pollution-free.It is very convenient to construct, and has shortened the duration, reduces cost.
