Description

Auxiliary supporting device for cast-in-situ beam swivel construction

Technical Field

The utility model relates to the field of auxiliary devices for cast-in-situ beam construction. More particularly, the utility model relates to an auxiliary supporting device for cast-in-situ beam swivel construction.

Background

In recent years, in order to solve the limit of terrains and existing traffic lines on bridge construction, bridge swivel construction is increasingly adopted, namely, a construction mode of manufacturing cast-in-place beams at non-design axis positions and then locating by swivel is adopted. However, as the length and the rotation angle of the swivel beam Duan Xuanbei are increased, the vertical displacement caused by the unbalanced moment at the cantilever beam end is amplified due to the tiny rotation of the unbalanced moment generated by the rotating spherical hinge, so that the accurate test of the unbalanced moment and the quality control of a rotating system in reasonable balance weights are very important. In the existing counterweight mode, a water bag is adopted to carry out counterweight for realizing accurate control of the counterweight weight, but the counterweight mode has high requirement on reliability and complex operation; the other mode adopts the rail and the counterweight car to achieve the aims of accurately controlling the position of the counterweight and reducing the labor intensity of personnel, but the mode has higher cost and needs to be matched with electric control. Therefore, many projects still select a ton bag filled with crushed stone as a counterweight from the comprehensive consideration of reliability, cost and construction convenience. However, when the weight is large, the stacking of ton bags is unstable, so that the center of the whole weight deviates from the position where the weight is arranged, and the quality of a beam body rotator is affected; and the device is inconvenient to move and cannot flexibly adapt to the adjustment of the position of the counterweight.

As shown in fig. 1 and 2, the present utility model provides an auxiliary supporting device for cast-in-situ beam rotation construction, a ton bag for supporting a ton bag for weight distribution in cast-in-situ beam rotation construction, comprising: the support screws 1 are arranged in a matrix, wherein the bottoms of the support screws 11 positioned at the center are fixedly connected with the top surface of the cast-in-situ beam, universal wheels 5 are arranged at the bottoms of the rest support screws 1, and the diameters of the universal wheels 5 are not larger than the diameters of the support screws 1; a base 4 is sleeved at the lower end of each supporting screw 1, and the base 4 is in threaded connection with the supporting screw 1; a cross brace 2 is arranged between two adjacent support screws 1, two ends of the cross brace 2 are respectively provided with a connecting piece 3, and the connecting pieces 3 are used for being detachably connected with the corresponding support screws 1; the length of the cross brace 2 is not smaller than the width of the ton bag, so that four rectangular supporting screws 1 are arranged to form a ton bag accommodating space.

In this solution, the support screw 11 in the central position is first fixed to the set counterweight point to ensure that the center of the counterweight constituted by the respective ton bags coincides with the set counterweight point. Then, the rest supporting screws 1 are sequentially connected through the transverse supporting rods 2 to form a matrix structure as shown in fig. 2, the nine supporting screws surround through the transverse supporting rods 2 to form four accommodating spaces 6 with the supporting screws 11 as the center, and four ton bags can be placed in the same horizontal plane. When in actual use, the number of the supporting screw rods 1 and the transverse supporting rods 2 can be determined according to the number of the ton bags corresponding to the required weight amount. The transverse supporting rod 2 is used for providing support for the ton bags on the side wall, preventing the ton bags from being inclined, and simultaneously connecting the supporting screw rods 1 to form a whole, so that after each ton bag is placed, a balancing weight taking the supporting screw rods 11 as the center is naturally formed, and further the precision of balancing weight and weighing in the cast-in-situ beam swivel construction is ensured.
