Description

The fast adjustment method of pre-pressing bracket sedimentation absolute altitude

Technical field

The present invention relates to field of bridge construction, the fast adjustment method of specifically a kind of pre-pressing bracket sedimentation absolute altitude.

Background technique

Currently, construction site adjusts the step for formwork elevation measuring to designed elevation in construction bridges template, after precompressed In, each bracket will measure calculating adjustment height and then just correspond adjustment, and this method is time-consuming and laborious, significantly Increase the workload and construction cost of construction；And formwork after-poppet is intensive, and measurement sight is usually blocked to more The complexity for increasing workload and measurement, reduces the accuracy of measurement data.

Summary of the invention

It is an object of the invention to overcome drawbacks described above, measurement accuracy can be accelerated and guarantee data accuracy by providing one kind Pre-pressing bracket settle absolute altitude fast adjustment method.

In order to achieve the above object, the present invention is implemented as follows:

A kind of fast adjustment method of pre-pressing bracket sedimentation absolute altitude, including

After step 1, template install, each bridge is respectively in both ends and intermediate six points of arrangement altogether；

Step 2, at six points chosen respectively by a #12 or more than reinforcing bar throw into down toward fixation, exposed parts For 1m, reinforcement location is located at selected plummet hitch point side in order to measurement later, and reinforcing bar and ground junction are with red Paint application label, in order to observe whether reinforcing bar has sedimentation phenomenon, to prevent subsequent calculations from error occur；

Step 3 is divided on each gang mould board ends and middle, the support beam at bottom die of box-beam plate and at flange template Not Xuan Gua a plummet, totally six, hang specifically: plummet is hung on support beam at the edge of a wing, and plummet is outstanding at bottom plate It is hung on and clenches on the nail of support beam；

Before step 4, non-precompressed, the inverted cone bottom surface and reinforcing bar face of plummet maintain an equal level；After precompressed, template sedimentation is driven under plummet Drop, have height difference H between inverted cone bottom surface and reinforcing bar top surface, by H with measure non-precompressed front template height H1 and template it is pre- After adjustment height is calculated in pressure settling amount H, the respective holder of six points is adjusted first, then constitutes every two point Plane, the bracket between totally three planes by between two points draw a tight straight line be adjusted.

Bracket needed for this fast adjustment method is set up conveniently, and observation is intuitive, measurement is accurate, is reduced pre-pressing bracket sedimentation and is adjusted Whole required time, accelerates speed of application, improves work efficiency, reduces construction cost.

Detailed description of the invention

Fig. 1 is the erection schematic diagram of six measurement points in this method of adjustment.

Fig. 2 is measurement process schematic diagram one in this method of adjustment.

Fig. 3 is measurement process schematic diagram two in this method of adjustment.

Specific embodiment

The present invention is further illustrated below by way of specific embodiment.

A kind of fast adjustment method of pre-pressing bracket sedimentation absolute altitude, including

As shown in Figure 1, each bridge is respectively in both ends and intermediate six points of arrangement altogether after step 1, template install；

Step 2, at six points chosen respectively by a #12 or more than reinforcing bar 1 throw into down toward fixation, exposed parts For 1m, 1 position of reinforcing bar is located at selected 2 hitch point side of plummet in order to which measurement later, reinforcing bar 1 and ground junction are used Red paint smears label, in order to observe whether reinforcing bar has sedimentation phenomenon, to prevent subsequent calculations from error occur；

Step 3 is divided on each gang mould board ends and middle, the support beam at bottom die of box-beam plate and at flange template Not Xuan Gua a plummet 2, totally six, hang specifically: at the edge of a wing plummet hang on support beam on, plummet 2 at bottom plate It hangs on and clenches on the nail of support beam；

Before step 4, non-precompressed as shown in Figure 2, the inverted cone bottom surface and 1 face of reinforcing bar of plummet 2 maintain an equal level；After precompressed, template sedimentation Drive plummet 2 decline, have height difference H between inverted cone bottom surface and reinforcing bar top surface, by H and measurement non-precompressed front template height H1 with And after adjustment height is calculated in the preloading amount H of template, as shown in figure 3, the respective holder of six points is adjusted first Good, the plane for then constituting every two point, the bracket between totally three planes by drawing a tight straight line between two points It is adjusted.

Bracket needed for this fast adjustment method is set up conveniently, and observation is intuitive, measurement is accurate, is reduced pre-pressing bracket sedimentation and is adjusted Whole required time, accelerates speed of application, improves work efficiency, reduces construction cost.
