Description

Measuring and paying-off platform for foundation slab

Technical Field

The utility model relates to a measurement unwrapping wire platform for soleplate belongs to construction technical field.

Background

The engineering measurement paying-off is an indispensable construction process in a construction stage, and the elevation measurement and the axis throwing in a foundation stage are particularly important and are starting points of the elevation and the size positioning of the whole engineering.

At present, no matter civil buildings or public buildings are adopted, the foundation form is mostly designed into a piled raft foundation. Pile raft foundation need carry out the axis location to the raft surface course once more after raft bar ligature is accomplished, before concrete placement, provides the location foundation for vertical member's joint bar. Simultaneously, after the joint bar is accomplished, still need to direct survey the control elevation to the joint bar on, provide the basis for raft concrete placement's elevation control on the one hand, on the other hand provides the control elevation for hanging mould position.

The axis throwing and elevation guiding measurement can not be separated from measuring instruments such as a level gauge, a theodolite and the like, although the guiding control points and the control elevation for controlling the axis are arranged on the periphery of the foundation pit, the measuring instruments often have to be erected on raft steel bars for measurement due to too long distance or shielding of objects. However, when the axial throwing and elevation guiding are performed on the raft steel bars, the raft steel bars are easy to shake due to the fact that other workers still work, mechanical vibration, personnel walking and other factors, so that the measuring instrument shakes, and the accuracy of measured data is affected.

Although the measurement paying-off platform has been developed and applied by technical innovators in the construction industry for a long time, the measurement paying-off platform applied at present is very simple and is only a flat plate and a stable lower support, and if the measurement paying-off platform is placed on a steel bar of a bottom plate for use, the following unreasonable places exist: 1. the platform is single in height and cannot be applied to rafts with different thicknesses; 2. the platform support is welded to be dead and cannot be adjusted, the interval between the steel bars designed by the drawing is the theoretical interval, and the smooth placement of the platform is influenced finally due to the fact that deviation exists; 3. the platform dead weight is heavier, can not be as easy as the text description when actually placing, even if insert the supporting leg in the reinforcing bar net smoothly, also can't avoid not touching the raft reinforcing bar, during the use, still receives the reinforcing bar vibration to influence.

The limitation of instrument erection supporting points welded by using the engineering pile steel bar lengthening is very large, only individual measuring instrument erection points can be arranged, and the stability must be ensured when the supporting points are arranged, and the instrument erection supporting points cannot be in contact with a steel bar net, so that the manufacturing workload must be greatly increased if the instrument erection supporting points are excessively arranged. Meanwhile, if the engineering pile at the non-axis intersection position is used as an instrument installation point, the throwing of the auxiliary axis during measurement paying-off can be increased, the workload of measurement paying-off is increased, and the measurement paying-off precision is reduced. When the supporting points are used, the supporting points need to be cut off, and because the pile types are different, the heights of the raft plates are different, and the cut-off supports cannot be reused.
