Technical Field

[0001] This utility model relates to the field of crane foundation technology, and in particular to a prefabricated foundation for a crane. Background Technology

[0002] With the continuous development of the national economy, the construction industry has grown rapidly, with multi-story and high-rise buildings constantly increasing in major and medium-sized cities. Tower cranes are being used more and more widely, becoming an important method of vertical transportation in the construction of multi-story and high-rise buildings. The application of tower cranes plays an increasingly important role in accelerating construction progress, shortening construction periods, and reducing costs. With the increase in national investment in infrastructure construction and the implementation of affordable housing projects, their application areas are constantly expanding.

[0003] Currently, tower cranes in construction mostly use fixed foundations with integral cast-in-place concrete. The drawback of this is that it leaves permanent construction waste next to the building after construction, causing difficulties in cleaning up and serious waste of resources.

[0004] Therefore, there is an urgent need in this field for a new type of prefabricated foundation for cranes to solve the above problems. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] The purpose of this utility model is to provide a prefabricated foundation for a crane to solve the problems existing in the prior art. The whole is assembled from prefabricated blocks, which reduces the construction time on the construction site and produces less construction waste. In addition, the presence of counterweights can enhance the overall stability.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Example 1

[0027] like Figures 1-2 As shown, this embodiment provides a prefabricated foundation 100 for a crane, including a support base 1. A prefabricated block assembly 2 is provided at the upper end of the support base 1, and the upper surface of the prefabricated block assembly 2 is used to mount the bottom of a tower crane. The prefabricated block assembly 2 includes several prefabricated block units, which can be assembled according to the expected structure, and each prefabricated block unit is fixed to the upper surface of the support base 1. Multiple counterweights 4 are also placed on the support base 1 to ensure the stability of the support base 1 and the prefabricated block assembly 2.

[0028] In practical use, the lower end of the tower crane's support is bolted to the corresponding precast block unit. The distribution and quantity of the counterweight blocks 4 can be adjusted according to the actual site conditions.

[0029] In this embodiment, the support base 1 is a common concrete foundation, and the concrete foundation is cast on site.

[0030] In other embodiments, the support base 1 can also be a precast concrete slab, which can be directly installed at the construction site by bolts in actual use.

[0031] In this embodiment, the prefabricated block component 2 has a cross-shaped structure, which can be understood as the individual prefabricated blocks being assembled into a cross-shaped structure. This is a common shape structure in tower crane foundations. Of course, those skilled in the art can also adjust the distribution of the individual prefabricated blocks to assemble them into other shapes, such as rectangles, and are not limited to the cross-shaped structure.

[0032] In this embodiment, the precast block assembly 2 includes a central precast block 201 and several connecting precast blocks 202. Both the central precast block 201 and the connecting precast blocks 202 are concrete blocks, and both can be ordinary rectangular blocks. Figure 1 As shown, each of the four sides of the central precast block 201 is connected to a number of connecting precast blocks 202 in sequence. That is, the connecting precast blocks 202 connected to each side of the central precast block 201 are connected end to end in a straight line.

[0033] During the actual installation of the tower crane, four corresponding prefabricated connecting blocks 202 are installed at the four corners of the lower end of its support.

[0034] In this embodiment, each side of the central precast block 201 is connected to 3-4 connecting precast blocks 202. Of course, the specific number of connecting precast blocks 202 can be adjusted according to factors such as the area of ​​the supporting base 1 and the size of the connecting precast blocks 202, and is not limited to just 3-4.

[0035] In this embodiment, the connecting prefabricated block 202 is provided with a plurality of fixing holes 3. The specific number can be adjusted according to the actual situation, so it is not limited here. The connecting prefabricated block 202 is fixed to the support base 1 by fixing bolts passing through the fixing holes 3, which facilitates installation and ensures a tight connection.

[0036] In this embodiment, several counterweights 4 are provided on each of the four sides of the support base 1, from... Figure 2 As can be seen, each side of the support base 1 is equipped with two counterweights 4, which are distributed vertically. Of course, the specific distribution and number of counterweights 4 need to be adjusted according to factors such as the actual stability of the support base 1 and the weight of the counterweights 4, so they will not be elaborated on here.

[0037] In this embodiment, the area between the counterweights 4 on the adjacent sides of the support base 1 is a passageway for personnel. The advantage of this arrangement is that it facilitates the movement of workers during construction without having to cross the counterweights 4 which are relatively high.

[0038] In this embodiment, the counterweight 4 is a trapezoidal block. Alternatively, it can also be... Figure 1 Any hexagonal block resembling a trapezoid can be used. The key is that a passageway can be formed between two adjacent counterweight blocks 4 to facilitate worker access.

[0039] In this embodiment, adjacent connecting prefabricated blocks 202 are sequentially fixed together by connectors 5. Specifically, as follows... Figure 1As shown, the precast block components 2 are arranged in a cross shape, so they can be regarded as two straight lines, and each precast block on each straight line is fixed by several connectors 5 passing through it in sequence.

[0040] As for the specific structure of connector 5, it can be an existing anchor rod or anchor cable. After the anchor rod or anchor cable is tensioned, a rubber plug can be installed at its end. These are all existing technologies, so they will not be described in detail here.

[0046] Step four: Install the lower end of the tower crane's support to the upper end of the precast block assembly 2 using bolts.
