As shown in fig. 1, the present invention comprises the steps of:
step A: when the base of the spherical hinge is poured with the cushion, a cushion mould is placed, and then a plurality of supporting steel bars with the same height are vertically and uniformly arranged in the cushion mould in a circle with the center of the cushion mould as a circle and the radius of the circle being 10cm smaller than the radius of the spherical hinge as a radius;
in the step A, the supporting steel bars are uniformly arranged in a rotationally symmetrical mode by embedding one supporting steel bar in every 60 degrees, the number of the supporting steel bars in the step A is six, and the length of the supporting steel bars is 0.3m phi 25, so that the supporting load is met, and the difficulty of polishing in the subsequent steps is not increased due to excessive arrangement.
And B, in the step A, the top height of the pre-buried supporting steel bar is 5cm greater than the bottom height of the spherical hinge. The supporting steel bar with the height being greater than 5CM of the spherical hinge bottom can prevent the height after the height error is not smaller than the spherical hinge bottom elevation within the allowable range of the angle inclination error when the supporting steel bar is poured for the first time in the following step B and is not absolutely vertical when the steel bar is stable, so that the hinge bottom elevation after the ball is installed is ensured.
And B: performing first pouring in the stone-padding mould, wherein the first pouring height is smaller than the bottom elevation of the spherical hinge, and when the supporting steel bars have vertical stability, cutting and polishing the top ends of the pre-embedded supporting steel bars by using an angle grinder until the bottom elevations of the spherical hinges are consistent; and in the step B, the first pouring height is 2cm lower than the bottom elevation of the spherical hinge.
And C: then hoisting the spherical hinge and arranging the spherical hinge on the support steel bar to ensure that the spherical hinge is stably fixed on the support steel bar;
step D: and then, carrying out secondary grouting in the stone-padding mould at the bottom of the spherical hinge, and filling mortar between the spherical hinge and the stone-padding mould, so that the flatness effect within 1mm of height difference can be directly achieved.
According to the method, the pouring of the cushion stone is divided into two times, the bottom elevation of the spherical hinge is accurately positioned by arranging the supporting steel bar during the first pouring of the cushion stone, the spherical hinge is fixed by the supporting steel bar, and then the cushion stone is poured for the second time, so that the top surface of the poured cushion stone and the bottom surface of the spherical hinge are arranged in a seamless mode, the problem of combination of the surface of the cushion stone and the surface of the spherical hinge is well solved, and on the premise that the bottom surface of the spherical hinge is horizontal, the error of the combination surface of the top surface of the cushion stone and the bottom of the spherical hinge after the second pouring can be 0 theoretically. The inevitable error that prior art center manual work was smoothed has been solved fine.
Before the base of the spherical hinge is poured, the base is internally embedded with a supporting steel bar every 60 degrees by taking the center of the base as a circle and the radius of the base is 10cm smaller than that of the spherical hinge, the supporting steel bars are rotationally and symmetrically arranged, the total number of the embedded 6 supporting steel bars is 0.3m phi 25, and the top height of the embedded supporting steel bars is the sum of the bottom elevation of the spherical hinge and 5 cm. And after the pouring of the cushion stone is finished, cutting and polishing the embedded support steel bars by using an angle grinder until the height of the bottom of the spherical hinge is within 1 mm. Then the hoisting ball hinge is arranged on the support steel bar and filled with mortar, and the flatness effect within 1mm of height difference can be directly achieved.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
