The leveling support assembly 11 includes a spacer 111, a steel pipe 112, a jacking 113 and a pallet 114. The spacer 111 is fixed on the ground where the legs of the heavy tower crane are pre-buried. The steel pipe 112 is vertically fixed to the gasket 111. The jacking 113 includes a nut 1131 and a screw 1132. The nut 1131 is provided at the upper end of the steel pipe 112 and is rotatable with respect to the steel pipe 112. Screw 1132 is disposed vertically and is threaded with nut 1131, with the lower end extending into steel tube 112. Specifically, as shown in fig. 3, the bottom end of the nut 1131 has a groove, which matches with the upper end of the steel pipe 112 and is sleeved on the upper end of the steel pipe 112. Preferably, the nut 1131 has handles on both sides to facilitate threading during leveling. The pallet 114 is fixed to the top end of the screw 1132 and moves up and down with the screw 1132. The heavy duty tower crane pre-buried legs are secured to the pallet 114. The nuts 1131 are screwed, the screws 1132 move up and down, and the jacking 113 fixed with the embedded supporting legs of the heavy tower crane moves up and down along with the nuts 1131, so that leveling can be realized, namely, leveling can be realized by adjusting the nuts 1131 of the jacking 113 of the plurality of groups of leveling support assemblies 11. The three sets of leveling support members 11 are arranged at the vertices of a triangle.
The first fixing bar assembly 12 includes three first fixing bars 121. The two ends of the first fixing reinforcement 121 are respectively fixed with the two steel pipes 112 of the adjacent two sets of leveling support assemblies 11, thereby fixing the plurality of steel pipes 112 in the same leveling support unit 1.
The second fixing bar assembly 13 includes three second fixing bars 131, and both ends of the second fixing bars 131 are respectively fixed with the two first fixing bars 121 in a triangular arrangement, thereby further fixing the aligning and supporting unit 1.
The four leveling support units 1 are equal in number to the pre-buried support legs of the heavy-duty tower crane, correspond to each other one by one and serve as bases of the pre-buried support legs of the heavy-duty tower crane. The three supporting plates 114 of the leveling supporting unit 1 are fixed with the embedded supporting legs of the heavy tower crane corresponding to the leveling supporting unit 1.
The fixed reinforcement unit 2 includes a plurality of unit fixed reinforcements 21. Both ends of the unit fixing bar 21 are respectively fixed with the steel pipes 112 of the two leveling support units 1, thereby fixing the plurality of leveling support units 1.
The pad 111 mainly plays roles of increasing the stress area and ensuring the ground to be flat. The steel pipe 112 is a main supporting structure, and an operation space for adjusting the jacking 113 is reserved when the length of the steel pipe 112 is determined. The jacking 113 is of an adjusting structure, specifically, when in use, the screw 1132 is driven to rotate by screwing the nut 1131, so that the functions of adjusting the elevation and the levelness of the embedded support leg of the heavy tower crane are achieved. The pallet 114 may also function to increase the area of force. The first fixing reinforcement 121, the second fixing reinforcement 131 and the unit fixing reinforcement 21 all play a fixing role, and the leveling support assembly 11 is prevented from being shifted in the placing and mounting process of the embedded support leg of the heavy tower crane.
In this embodiment, the dimensions of the spacer 111 are 150mm by 8mm. The steel pipe 112 has a gauge of phi 48mm. The screw 1132 of the jacking 113 has a gauge of phi 30mm. The dimensions of the pallet 114 are 150mm by 8mm. The first fixing bars 121, the second fixing bars 131, and the unit fixing bars 21 are C25 bars.
Of course, the number of the leveling supporting components 11 in the leveling supporting unit 1 can be more than three, and the gasket 111, the steel pipe 112, the jacking 113, the supporting plate 114, the first fixing reinforcing steel bar 121, the second fixing reinforcing steel bar 131 and the unit fixing reinforcing steel bar 21 can be of other sizes and specifications, which can be adjusted according to the size and weight of the embedded supporting leg of the heavy-duty tower crane.
The construction method of the leveling and supporting device for the embedded supporting leg of the heavy-duty tower crane comprises the following steps:
step one, manufacturing a leveling support assembly 11: and cutting out the needed accessories such as the steel pipes 112 with corresponding lengths according to the height of the pre-buried support legs of the on-site heavy tower crane. The bottom layer is a gasket 111, so that the ground is flat, and the stressed area is increased. The steel pipe 112 is then fixed to the spacer 111. The nut 1131 of the jacking 113 is then placed on the upper end of the steel pipe 112, and the screw 1132 is screwed into the nut 1131 and extends into the steel pipe 112. Finally, the supporting plate 114 is fixed on the screw 1132, and the standard height and levelness are adjusted, so that the manufacturing of the leveling support component 11 is finally completed. When manufacturing different sets of leveling support members 11, it is necessary to ensure that the steel pipes 112 are on the same plane to maintain stability.
Step two, manufacturing a leveling supporting unit 1: three groups of leveling support assemblies 11 are combined into a leveling support unit 1 according to the foot size of the embedded support leg of the heavy tower crane, and specifically: the steel pipes 112 of the three groups of leveling support assemblies 11 are welded together by using the first fixing steel bars 121 and the second fixing steel bars 131, so that firmness is ensured. Finally, by adjusting the jacking 113, the levelness fine adjustment can be performed.
Step three, installing a leveling supporting device: after binding of the reinforcing steel bars at the bottom of the tower crane is completed, the four leveling supporting units 1 are placed on four side lines at the bottom of the foundation according to the size of the pre-buried drawing installation drawing, and then the four leveling devices are fixed through the unit fixing reinforcing steel bars 21, so that shaking during foundation pouring is avoided. The whole device takes a steel pipe 112 as a supporting main body, and a jacking 113 is a leveling structure.
Finally, the tower crane positioning frame and the supporting legs are integrally hoisted, so that the embedded supporting legs are positioned at the designed elevation positions, and the jacking 113 below the supporting legs is adjusted to realize the elevation of the embedded supporting legs.
