Abstract
The utility model relates to a double-acting stepless height-adjustable steel device. When a support realizes a function of adjusting the height, a plurality of steel plates with different thicknesses are inserted between the bottom of the support and a lower embedded steel plate, so that the height of the support is adjusted, but the height cannot be accurately adjusted. The steel device is provided with an upper height-adjusting support plate and a lower height-adjusting support plate which are provided with circumferential outer threads, and both threads are arranged in reverse direction; height-adjusting nuts with inner threads are arranged at the peripheries of the upper height-adjusting support plate and the lower height-adjusting support plate; and lock loops are arranged at the peripheries of the upper height-adjusting support plate and the lower height-adjusting support plate close to the edges of the height-adjusting nuts. The double-acting stepless height-adjustable steel device is clear in force transferring lines, is stably and reliably stressed, and is convenient to assemble and adjust; and the adjustment is in linear variation, so that the height of the support can be steplessly adjusted, and the adjustment can be accurately controlled. The double-acting stepless height-adjustable steel device has the function of steplessly raising and lowering the height when combined with an ordinary support, and has the functions of steplessly raising and lowering the height and resisting tension and compression when used along with a tension-compression support.
Description
Technical field
The utility model relates to the parts of a kind of bridge and other construction work support usefulness, is specifically related to a kind of two moving stepless formula steel device of heightening.
Background technology
Bearing is the vitals that is connected superstructure and substructure in bridge and the construction work, and its basic function is that the upper load with structure is delivered in the substructure through bearing, guarantees the needs of desired stressed, displacement of structure and rotation simultaneously.Therefore, generally speaking, require bearing can satisfy the stepless requirement of heightening.And when bearing is realized heightening function; Usually between between rest base and the following pre-embedded steel slab or bearing top and last pre-embedded steel slab (rise plain plate), insert and the steel plate of heightening some thickness of hight coordinate; Realize heightening of bearing; But this kind bearing heighten the restriction that receives steel plate thickness, can not accurately heighten.Also have some bridges to require bearing not only will have the stepless function of heightening, turn down, also require bearing can bear pressure, therefore, this design to bearing has proposed a unprecedented difficult problem.
Summary of the invention
The purpose of the utility model provides a kind of ability and realizes the accurately stepless two moving stepless formula steel device of heightening of heightening.
The technical scheme that the utility model adopted is:
A kind of two moving stepless formula steel device of heightening is characterized in that:
Described steel device is provided with has externally threaded height-adjustable supports plate and the following height-adjustable supports plate gone up of ring week, and the two screw thread oppositely is provided with;
The described periphery that goes up height-adjustable supports plate and following height-adjustable supports plate is arranged with the nut of heightening with internal thread.
The described height-adjustable supports plate of going up is provided with locking lasso with the adjacent edge that heightens nut of following height-adjustable supports plate periphery.
The described height-adjustable supports plate of going up is fixed through last anchor bolt;
Described height-adjustable supports plate is down fixed through following anchor bolt.
The utlity model has following advantage:
The power transmission clear route of the utility model, stability under loading is reliable, and convenient mounting and regulation, regulated quantity are linear change, can realize the step-less adjustment of height of support, and regulated quantity can be controlled accurately.Can carry out the split assembling with common bearing (but containing tension compression bearing) and use, also can lower support plate that go up height-adjustable supports plate or following height-adjustable supports plate and common bearing (but containing tension compression bearing) or upper bracket plate be designed to whole the use.
Description of drawings
Fig. 1 is that the vertical bridge of the utility model is to structural representation.
Fig. 2 is the direction across bridge structural representation of the utility model.
Among the figure, the last height-adjustable supports plate of 1-, the locking lasso of 2-, 3-heightens nut, height-adjustable supports plate under the 4-, the last anchor bolt of 5-, anchor bolt under the 6-.
The specific embodiment
Below in conjunction with the specific embodiment the utility model is carried out detailed explanation.
The described a kind of two moving stepless formula steel devices of heightening of the utility model are provided with to have and encircle all externally threaded height-adjustable supports plate 1 and following height-adjustable supports plates 2 gone up, and the two screw thread oppositely is provided with.Last height-adjustable supports plate 1 is fixed through last anchor bolt 5, and following height-adjustable supports plate 4 is through anchor bolt 6 is fixing down.The periphery of last height-adjustable supports plate 1 and following height-adjustable supports plate 4 be arranged with have an internal thread heighten nut 3.When heightening, through rotation heighten nut 3 regulate height-adjustable supports plate 1, down height-adjustable supports plate 2 near with deviate from, can be from the accurate step-less adjustment of implementation structure vertical height on the both direction up and down.Last height-adjustable supports plate 1 is provided with locking lasso 2 with the adjacent edge that heightens nut 3 of following height-adjustable supports plate 4 peripheries, and overall structure is fixed.
This bearing can with the new compound supports of stacked fixedly composition such as other bearings such as tension pressure ball shape bearing, damping shock absorption bearing, the function of multiple bearing is integrated, make that its applicable situation is more extensive.
