Embodiment 1

[0026] Example 1: Combining figure 1 and figure 2 Illustrate the composite tower crane foundation 10 of the present invention. In this embodiment, the tower cranes (not shown) whose models are ST5513 and ST6015 are taken as examples. The distance between two adjacent legs. The composite tower crane foundation 10 includes a concrete foundation 11 arranged on the ground; two sets of pre-embedded components anchored in the concrete foundation 11 are respectively a pre-embedded component 12 corresponding to the tower crane one (ST5513), and a The second embedded component 13 corresponding to the second tower crane (ST6015); each set of embedded components 12, 13 includes four embedded parts 17 that can be connected to the four foot bolts of the corresponding tower crane body, and the embedded component one 12 and the embedded part 17 of embedded assembly two 13 are arranged alternately. The reinforcement in the above-mentioned concrete foundation 11 is a double-layer two-way s...

Embodiment 2

[0032] Embodiment 2: Combination image 3 and Figure 4 The composite tower crane foundation 20 of the present invention is different from the first embodiment in that the concrete foundation 21 of the present embodiment is provided with two sets of embedded components 22, 23, which are similar to the tower cranes whose models are QTZ80 and STL230 respectively. Correspondingly, the embedded part 24 is a cylinder vertically arranged in the concrete foundation 21. The bottom end of the cylinder is in the shape of a truncated cone, and the end with a larger outer diameter at the bottom of the embedded part 24 is close to the bottom surface of the concrete foundation 21. , the top of the embedded part 24 is connected with the foot bolts of the tower body. The above-mentioned embedded parts 24 are firmly embedded in the concrete foundation 1, and are non-detachable embedded parts. Compared with the embedded parts in the first embodiment above, the structure of the embedded parts in ...

Embodiment 3

[0033] Example Three: Combining figure 1 and figure 2 Illustrate the construction method of the composite tower crane foundation of embodiment one, concrete steps are as follows:

[0034] 1. Erection of the reinforcement cage and formwork (not shown in the figure) in the concrete foundation 11 to be poured. The reinforcement cage is composed of double-layer two-way reinforcement mesh sheets, and a pre-embedded component 12 and a number of pre-embedded bolts 14 are arranged in the reinforcement cage , and the pre-embedded component 12 and the pre-embedded bolt 14 are welded and fixed with the reinforcement cage;

[0035] 2. Connect the four embedded parts bolts of the embedded component 2 13 to the plane positioning frame 15, and a number of embedded bolts 14 are fixed to the embedded parts, and the plane positioning frame 15 connected with the embedded component 2 13 is inserted into the Reinforcement cage, and the embedded parts of the embedded component 12 and the embedde...

Abstract

The invention discloses a combined tower crane foundation and a construction method thereof, relates to the technical field of auxiliary equipment for fixing tower cranes, and aims at the problem that a certain limitation exists in tower crane selection during a construction process due to the fact that an existing tower crane foundation is capable of fixing tower cranes of only one type. The compound tower crane foundation comprises a concrete foundation and two sets of embedded assemblies, wherein the two sets of embedded assemblies are anchored in the concrete foundation, and are respectively an embedded assembly I corresponding to a tower crane I, and an embedded assembly corresponding to a tower crane II; each set of embedded assemblies comprises four embedded parts which can be connected with four supporting foot bolts of a tower body of the corresponding tower crane, and the embedded parts of the two sets of embedded assemblies are arranged in a staggered manner. The construction method comprises the following steps: erecting a reinforcement cage and a template in the concrete foundation to be poured, and mounting and fixedly connecting the embedded assembly I and embedded bolts in the reinforcement cage; connecting the four embedded parts of the embedded assembly II onto a planar positioning frame and placing the planar positioning frame into the reinforcement cage, and enabling the embedded parts of the two sets of embedded assemblies to be arranged in a staggered manner; pouring the concrete, and after the concrete reaches strength of the design requirement, dismantling the planar positioning frame.

Description

technical field [0001] The invention relates to the technical field of auxiliary equipment for fixing tower cranes, in particular to a composite tower crane foundation and a construction method thereof. Background technique [0002] Tower crane is referred to as tower crane, also known as tower crane. It is a rotating crane with a boom installed on the upper part of a high tower. It is mainly used for vertical and horizontal transportation of materials in construction and installation of building components. [0003] The tower crane foundation is an important factor affecting the overall stability of the tower crane. At present, the tower crane foundation used in the construction site can only be equipped with a pair of foundation embedded parts to fix a type of tower crane, so that the tower crane will There are certain limitations in the selection. For example: in the construction of support and floor, you can choose a tower crane with a smaller lifting capacity; in the c...
