The utility model discloses be particularly suitable for the job site and use.
Description
Technical field
The utility model relates to a kind of precompressed charger, particularly a kind of precompressed charger of high pier top end support.
Background technology
Carry out precompressed to the bracket on Bridge High-pier platform, present stage adopts traditional piling prepressing mode to carry out.The sand pocket that piling prepressing is used or concrete precast block or water tank are transported on Bridge High-pier platform support by lifting.During with sand pocket or concrete block precompressed, need the project organization considering hanging box and suspension ring, also must consider during stacking to put slope, also want formwork erection if desired and establish pull bar, to ensure the safety of loading procedure.It is many to there is consume material in this mode of carrying out precompressed to Bridge High-pier platform bracket, and the load time is long, loads the defect that tonnage is difficult to accurately control.In addition, when Bridge High-pier platform support top width relative narrower, in work high above the ground environment, also there is huge potential safety hazard in a large amount of weight of preloading.
Summary of the invention
The utility model provides a kind of Bridge High-pier platform top end holder hierarchical loading device, and solve the consume material of existence when prior art carries out precompressed to Bridge High-pier platform bracket many, the load time is long, loads the technical problem that tonnage is difficult to accurately control.
The utility model solves above technical problem by the following technical programs:
A kind of Bridge High-pier platform top end holder hierarchical loading device, comprise Bridge High-pier pier shaft cushion cap 1, Bridge High-pier pier shaft cushion cap 1 is provided with Bridge High-pier pier shaft 2, Bridge High-pier pier shaft 2 is provided with top end holder 3, reinforced mesh 4 is embedded with in Bridge High-pier pier shaft cushion cap 1, the upper surface of reinforced mesh 4 is embedded with upper end pre-embedded steel slab 5, upper end pre-embedded steel slab 5 is embedded with ground tackle 6 on steel strand, the lower surface of reinforced mesh 4 is embedded with lower end pre-embedded steel slab 7, lower end pre-embedded steel slab 7 is embedded with ground tackle 8 under steel strand, the lower end of lower flexible cable 9 to be riveted on steel strand under ground tackle 6 and steel strand in ground tackle 8, high performance concrete 10 has been built in Bridge High-pier pier shaft cushion cap 1, the upper end of lower flexible cable 9 and the lower end of upper flexible cable 12 are linked together by flexible cable connector 11, top end holder 3 is provided with jack anchor set 13, the upper end of upper flexible cable 12 is connected in jack anchor set 13, top end holder 3 is provided with top end holder deformation test dial gauge 14.
4 cover hierarchical loading flexible cable devices are evenly equipped with between Bridge High-pier pier shaft cushion cap 1 and top end holder 3.
The utility model saves squeeze time, has saved experimentation cost, can the various situations of accurate simulation concrete uniform load and uneven load, is particularly suitable for job site and uses.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model on side-looking direction.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail:
