Summary of the invention
The joint that instant invention overcomes lower floor of the prior art precast concrete column needs cast-in-site, cannot ensure that flatness and post are high, do not meet design requirement, the shortcoming affecting structural safety, it is provided that a kind of device adjusting precast concrete column flatness and height.Meanwhile, a kind of method adjusting precast concrete column flatness and height is also provided for.
The present invention realizes the first goal of the invention and the technical scheme is that a kind of device adjusting precast concrete column flatness and height, described device includes oblique angle levelling device and vertical height supplementary device, described oblique angle levelling device includes: upper backup pad, lower supporting plate and the slide block of wedge shape, upper backup pad is hinged with lower supporting plate, the inner side of upper backup pad and lower supporting plate is equipped with chute, slide block two ends are inserted in chute and upper backup pad, lower supporting plate is slidably connected, upper backup pad, lower supporting plate and slide block form triangular structure, described vertical height supplementary device includes the steel cushion block that one group of thickness is different.
The present invention realizes the second goal of the invention and the technical scheme is that a kind of method adjusting precast concrete column flatness and height, comprises the following steps:
A., oblique angle as above levelling device is installed at the inclination of precast concrete column upper surface；
B. move the slide block of oblique angle levelling device described in step A, adjust the angle between upper backup pad and lower supporting plate, make upper backup pad be in level；
C. check whether the actual post height of four corner positions of precast concrete column reaches calibrated altitude, in the corner positions of not up to calibrated altitude, installing vertical height supplementary device as above highly to supplement, the corrected altitude after steel cushion block is high with standard column consistent to make corner positions add.
The invention has the beneficial effects as follows: by carrying out leveling at the inclination to precast concrete column upper surface of the oblique angle levelling device, it is ensured that the flatness of precast concrete column upper surface.Again by installing vertical height supplementary device on four angles of precast concrete column, make four angles high consistent plus the corrected altitude after steel cushion block and standard column.Lower floor's precast concrete column by with oblique angle levelling device, the coordinating of vertical height supplementary device, the indexs such as flatness and post are high are modified, meet design requirement, it is ensured that structural safety.
The invention will be further described with detailed description of the invention below in conjunction with the accompanying drawings.

In accompanying drawing, 1 be upper strata precast concrete column, 2 for lower floor's precast concrete column, 2-1 be at inclination, 3 be oblique angle levelling device, 3-1 be upper backup pad, 3-2 be lower supporting plate, 3-3 be that slide block, 3-4 are chute, 4 are vertical height supplementary device.
Detailed description of the invention
As shown in drawings, a kind of device adjusting precast concrete column flatness and height of the present embodiment, described device includes oblique angle levelling device 3 and vertical height supplementary device 4.Described oblique angle levelling device (3) including: the slide block 3-3 of upper backup pad 3-1, lower supporting plate 3-2 and wedge shape.Upper backup pad 3-1 and lower supporting plate 3-2 is arranged in connecting shaft, and upper backup pad 3-1 is hinged with lower supporting plate 3-2, and upper backup pad 3-1 and lower supporting plate 3-2 can relatively rotate shape and form an angle.The inner side of upper backup pad 3-1 and lower supporting plate 3-2 is equipped with chute 3-4.Slide block 3-3 two ends are slidably connected with upper backup pad 3-1, lower supporting plate 3-2 in inserting chute 3-4, and during mobile slide block 3-3, upper backup pad 3-1 changes with the angle of lower supporting plate 3-2, to meet the needs of differing tilt angles.Upper backup pad 3-1, lower supporting plate 3-2 and slide block 3-3 form triangular structure, and triangular structure is stable, can effectively support the upper strata precast concrete column 1 being placed on oblique angle levelling device 3.Described vertical height supplementary device 4 includes the steel cushion block that one group of thickness is different.By combining the steel cushion block of different-thickness, to adapt to fill up the needs of differing heights difference.
A kind of method adjusting precast concrete column flatness and height of the present embodiment, comprises the following steps:
A., oblique angle as above levelling device is installed at the inclination of precast concrete column upper surface, owing to oblique angle levelling device has enough weight and frictional force, the lower supporting plate of oblique angle levelling device is placed at inclination；
B. move the slide block of oblique angle levelling device described in step A, adjust the angle between upper backup pad and lower supporting plate, make upper backup pad be in level；
C. check whether the actual post height of four corner positions of precast concrete column reaches calibrated altitude, in the corner positions of not up to calibrated altitude, installing vertical height supplementary device as above highly to supplement, the corrected altitude after steel cushion block is high with standard column consistent to make corner positions add.By combining the steel cushion block of different-thickness, the high gap high with standard column of actual post of each corner positions filling up precast concrete column.Reach the corner positions of calibrated altitude, it is convenient to omit this step.
During actual job, after lower floor's precast concrete column 2 completes cast, check that the upper surface of lower floor's precast concrete column 2 is the most smooth, at the inclination of lower floor's precast concrete column 2,2-1 installs oblique angle levelling device 3, the lower supporting plate 3-2 of oblique angle levelling device 3 contacts with 2-1 at inclination, mobile slip 3-3, adjusts the angle of upper backup pad 3-1 and lower supporting plate 3-2, makes upper backup pad 3-1 be in level.After oblique angle levelling device 3 installation, check whether the actual post height of four corner positions checking precast concrete column reaches calibrated altitude, as being mounted with oblique angle levelling device 3 in corner positions, the corrected altitude after corner positions adds upper backup pad 3-1 should be calculated.In the corner positions of not up to calibrated altitude, vertical height supplementary device 4 is installed highly supplement, owing to the height of each corner positions may be inconsistent, need the steel cushion block by combining different-thickness, the high gap high with standard column of actual post at each angle filling up precast concrete column, the corrected altitude after steel cushion block is high with standard column consistent to make corner positions add.Lower floor's precast concrete column 2 by with oblique angle levelling device 3, the coordinating of vertical height supplementary device 4, the indexs such as flatness and post are high are modified, meet the design requirement installing upper strata precast concrete column 1, it is ensured that structural safety.
