Description

Assembled tower crane foundation

technical field

The utility model relates to a tower crane foundation, in particular to an assembled tower crane foundation.

Background technique

The foundation is one of the important components of the tower crane, and it is the final focus of the entire tower crane. The production of the foundation has high requirements. The existing foundation is mainly a concrete pouring type fixed foundation. The foundation needs to be compacted first, and the ground endurance meets a certain requirement, and then reinforced concrete is poured, and it solidifies for about ten days under natural conditions.

In the existing design, as shown in Figure 1, the fixed foundation needs to make a foundation pit, and the surrounding of the foundation pit should be compacted, a layer of cobblestones should be backfilled, bricks or molds should be laid around the foundation pit, and several layers of braided steel support should be placed , and pour the concrete. When pouring, pour the embedded outriggers together. After the pouring is completed, solidify for more than ten days in the natural state.

There is following defective in above-mentioned prior art:

1. The production cycle of the fixed foundation is long and the process is complicated. After the pouring is completed, the foundation is dislocated and cannot be connected with the tower body;

2. It cannot be moved after use, and can only become construction waste, which cannot be recycled again. The fixed legs of the pouring must be cut off, resulting in waste of resources.

Utility model content

Aiming at the problems existing in the above-mentioned prior art, the utility model provides an assembled tower crane foundation, which is simple to manufacture and has a short cycle, which avoids the phenomenon that the foundation cannot be connected with the tower after pouring is completed; the installation process is simplified and disassembly is convenient , Transshipment, recyclable recycling, improve economy.

In order to achieve the above purpose, the assembled tower crane foundation includes a plurality of assembled foundation blocks;

The inside of the basic block is welded by vertical plates and horizontal plates, and the outside is welded by steel structural parts, cover plate 1 and cover plate 2, forming a box structure.

Further, connecting fasteners are welded on the outer wall of the foundation block.

Further, the connecting fastener is a wedge-shaped hook structure.

Further, wedge-shaped blocks are placed in the gaps between adjacent foundation blocks.

Compared with the prior art, the foundation of the assembled tower crane adopts the assembled foundation structure, which has the following beneficial effects:

1. The production is simple and the cycle is short, which avoids the phenomenon that the foundation cannot be connected with the tower after the pouring is completed;

2. It simplifies the installation process, facilitates disassembly and transportation, and can be recycled and reused, which improves the economy.

detailed description

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

As shown in Fig. 2, Fig. 3 and Fig. 7, the foundation of the assembled tower crane includes a plurality of foundation blocks 3 assembled together;

The inside of the basic block 3 is welded by vertical plates 5 and horizontal plates 7 staggeredly, and the outside is welded by steel structural parts 4, cover plate 1 6 and cover plate 2 8, forming a box structure.

Further, as shown in FIG. 4 , FIG. 5 and FIG. 6 , connecting fasteners 9 are welded on the outer wall of the foundation block 3 . The mutual assembling and fixing between adjacent foundation blocks 3 is realized by a plurality of connecting fasteners 9 welded on the outer wall of the foundation blocks 3 .

Further, as shown in FIG. 5 and FIG. 6 , the connecting fastener 9 is a wedge-shaped hook structure. Through the wedge-shaped hook structure, mutual assembly and fixing among multiple foundation blocks 3 is realized, and the structure is stable and reliable.

Further, as shown in FIG. 7 , FIG. 8 and FIG. 9 , wedge-shaped blocks 10 are placed in the gaps between adjacent foundation blocks 3 . After the basic blocks 3 are assembled, the locking effect between the multiple basic blocks 3 is realized through the wedge block 10, and the structure is firm, safe and reliable.

As shown in Figure 7, the utility model is described with 16 basic blocks 3 as an embodiment, and the 16 basic blocks 3 of the box-type structure welded according to the above structure are placed and assembled in place sequentially, through the wedge-shaped hook structure. The connecting fasteners 9 realize the fixation between the various foundation blocks 3. After the assembly is completed, wedge-shaped blocks 10 are placed in the gaps between the adjacent foundation blocks 3 to realize the locking effect between the foundation blocks 3 and the foundation as a whole.

To sum up, the foundation of this assembled tower crane adopts an assembled foundation structure, which is simple to manufacture and has a short cycle, which avoids the phenomenon that the foundation cannot be connected to the tower after pouring is completed; the installation process is simplified, and it is convenient to disassemble and transfer , Can be recycled, improving the economy.
