Problems solved by technology

[0004] The vertical load transmitted to the ultra-thin shear wall by the support method of the traditional jib tower crane exceeds its bearing capacity. The existing methods for strengthening the ultra-thin shear wall have poor economic efficiency, high-altitude construction difficulty, and high safety risks. The problem of large amount of concrete and steel reinforcement

Embodiment 1

[0039] Example 1: Combining Figure 1 to Figure 7 Explain the climbing beam support system of the boom tower crane of the present invention. This embodiment takes the climbing beam support system of the inner climbing tower crane as an example to specifically illustrate its structure and connection relationship. It includes parallel and spaced beams along the climbing direction of the boom tower crane 2 The three support frames set are respectively support frame one 10, support frame two 20 and support frame three 30 from bottom to top, and are used to support the climbing jib tower crane 2; and are connected between the adjacent two support frames. Eight adjustable tie rod assemblies 50 for distributing the vertical load of the luffing jib tower crane 2;

[0040] Each support frame includes two parallel and spaced climbing beams 11, and the two ends of each climbing beam 11 are respectively connected with the embedded parts 5 bolts embedded in the shear wall 1, and are locate...

Embodiment 2

[0054] Embodiment two: different from embodiment one, as Figure 8 As shown, the adjustable tie rod assembly 50 of this embodiment includes a tie rod 51 connected sequentially from top to bottom, a flange joint 56 and an axial force servo automatic compensation device 57. The tie rod 51 is composed of a number of standard joints of the tie rod 51 connected by bolts. One end of the pull rod 51 is bolted to the top support frame, the other end of the tie rod 51 is bolted to the axial force servo automatic compensation device 57 through the flange joint 56, and the other end of the axial force servo automatic compensation device 57 is connected to the lower support frame through a ring buckle; Such as Figure 9 As shown, the axial force servo automatic compensation device 57 includes a hydraulic cylinder 571, a support seat 572, a push rod 573, at least two support frames 574, at least two locking blocks 577, at least two self-locking cylinders 576, and a PLC control unit (not s...

Embodiment 3

[0057] Example Three: Combining Figure 9 to Figure 12 The climbing beam support system of the boom tower crane of the present invention and its use method are described. The boom tower crane 2 of this embodiment is an external tower crane, that is, the three support frames are all fixed to the shear wall 1 on the same side. The frame includes two sets of triangular supports arranged in parallel and at intervals. Each triangular support is composed of two climbing beams 11 arranged at an angle and fixedly connected. Part 5 is connected by bolts, and other structures and usage methods of the climbing beam support system of the boom tower crane are the same as those in Embodiment 1 or Embodiment 2, and will not be repeated here. Therefore, the climbing beam support system of the boom tower crane of the present invention and its use method are suitable for various forms of boom tower cranes such as internal climbing and external attachment, and can be used in different forms of b...

Abstract

The invention provides a moving arm tower crane climbing beam supporting system and a using method thereof and relates to the technical field of building construction. The system aims at the problemsthat when an ultrathin shear wall is reinforced in the prior art, economy is poor, the high-altitude construction difficulty is large, and the safety risks are high. The system comprises at least three supporting frameworks arranged in parallel and at intervals, and multiple adjustable pull rod assemblies connected between the two adjacent supporting frameworks. Each supporting framework is connected with an embedded part bolt. A self-climbing device of a moving arm tower crane is fixed to the bottom supporting framework. A tower body is connected with the top supporting framework. The multiple adjustable pull rod assemblies are uniformly distributed on the outer side of the tower body. When the moving arm tower crane climbs, the third supporting framework is connected with the tower body,the second supporting framework and the third supporting framework are connected through the adjustable pull rod assemblies, constraint between the tower crane and the first supporting framework is loosened, the moving arm tower crane climbs upwards to the position of the second supporting framework and is connected with the second supporting framework, and so forth, it is always kept that vertical loads are borne together by the two adjacent supporting frameworks and the adjustable pull rod assemblies connected between the adjacent supporting frameworks.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a climbing beam support system for a boom tower crane used in a super high-rise building and a use method thereof. Background technique [0002] Luffing jib tower crane (hereinafter referred to as luffing jib tower crane), as one of the important vertical transportation equipment for super high-rise building construction, has been widely used in super high-rise building construction. The support arrangement of the jib tower crane is divided into two types: internal support and external suspension, and the climbing operation is often implemented in a self-climbing manner. Under normal working conditions, the inner-supported luffing jib tower crane has two climbing beams, among which the upper climbing girder mainly plays the role of horizontal fixed limit and horizontal bearing, while the vertical load and local horizontal force of the luffing jib tower crane are loc...
