Technical Field

[0001] The utility model belongs to the technical field of building construction, and particularly relates to a tower crane foundation structure that can be used for two purposes with one foundation. Background Art

[0002] At present, there are many buildings with structural form conversions. For example, the basement is a concrete frame-shear structure, and the above-ground part is a steel structure. For such buildings, the requirements for vertical transportation vary greatly during the construction process. In order to realize the replacement of different tower cranes in different construction stages, two independent tower crane foundations need to be built on the construction site, which will consume a large amount of materials such as steel bars and concrete, resulting in high construction costs. Therefore, we propose a tower crane foundation structure that can be used for two purposes with one foundation to solve the above problems. Content of the Utility Model

[0003] In order to solve the above problems, the utility model provides a tower crane foundation structure that can be used for two purposes with one foundation, and solves the problem of high construction costs.

[0010] A further improvement of the tower crane foundation structure that can be used for two purposes with one foundation of the utility model is that a end plate is arranged between the bottom of the second anchoring end of each heavy tower crane embedded part and the top of the corresponding lattice column, and they are welded and fixed through the end plate.

[0011] A further improvement of the tower crane foundation structure that can be used for two purposes with one foundation of the utility model is that the size of the bottom cross-section of the end plate is larger than the size of the top cross-section of the lattice column, and a plurality of stiffening ribs arranged at intervals and surrounding in a circle are fixedly connected between the area where the bottom of the end plate does not contact the lattice column and the outside of the lattice column.

[0012] A further improvement of the tower crane foundation structure with dual functions of the present utility model lies in that a plurality of first stiffening plates that enclose to form an inverted corbel structure are fixedly connected to the outside of each of the first anchoring ends, and the bottoms of the plurality of first stiffening plates are fixedly connected to the tops of the corresponding end plates.

[0013] A further improvement of the tower crane foundation structure with dual functions of the present utility model lies in that a plurality of second stiffening plates that enclose to form an inverted corbel structure are fixedly connected to the outside of each of the second anchoring ends, and the bottoms of the plurality of second stiffening plates are fixed to the tops of the corresponding fixing members.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

Install the corresponding type of tower crane according to the transportation requirements, and the conversion of the tower crane is the same as the installation and disassembly of ordinary tower cranes, with simple construction; the lattice column is connected to the heavy tower crane embedded part through the end plate, reducing the thickness of the concrete pile cap, reducing the self-weight of the foundation and the material consumption.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] In order to solve the problem of high construction cost, the present utility model provides a tower crane foundation structure with dual functions. The following further describes the tower crane foundation structure with dual functions with specific embodiments in conjunction with the drawings.

[0022] Refer to Figures 1 to 4 As shown, a tower crane foundation structure with dual functions includes:

[0023] Four lattice columns 2;

[0024] Four heavy tower crane embedments 4, which are respectively fixed at the tops of the four lattice columns 2; each heavy tower crane embedment 4 includes a first anchoring end 402 and a first connection end 401;

[0025] Four fixing members 5, which are respectively arranged between adjacent heavy tower crane embedments 4 and are used to connect and fix the four heavy tower crane embedments 4 to form a square;

[0026] Four light tower crane embedments 6, which are respectively fixed at the midpoint positions of the four fixing members 5; each light tower crane embedment 6 includes a second anchoring end 602 and a second connection end 601; and

[0027] A concrete bearing platform 1 for pouring a number of heavy tower crane embedments 4, a number of fixing members 5 and a number of light tower crane embedments 6 together to form a tower crane foundation structure, wherein the first connection end 401 of the heavy tower crane embedment 4 and the second connection end 601 of the light tower crane embedment 6 both protrude from the concrete bearing platform 1.

[0028] By pre-embedding two sets of tower crane embedments in the same foundation, it can be used for the conversion of two types of tower cranes in different construction stages. Install the corresponding type of tower crane according to the transportation requirements, and the tower crane conversion is the same as the installation and disassembly of ordinary tower cranes, with simple construction; compared with the traditional two separate tower crane foundations, the utility model reduces the material consumption and lowers the cost.

[0029] Among them, referring to Figure 4 As shown, between the bottom of the second anchoring end 602 of each heavy tower crane embedment 4 and the top of the corresponding lattice column 2, an end plate 3 is provided, and they are fixedly connected by welding through the end plate 3.

[0030] The lattice column 2 is welded to the heavy tower crane embedment 4 through the end plate 3, and then the concrete bearing platform 1 only wraps the first anchoring end 402 at the lower end of the heavy tower crane embedment 4, so that the lattice column 2 is connected to the bearing platform. Compared with the traditional method of anchoring the lattice column 2 into the bearing platform, the utility model can reduce the thickness of the concrete bearing platform 1, reduce the self-weight of the foundation and the material consumption, and lower the cost.

[0031] Among them, referring to Figures 3 - 4 As shown, the size of the bottom cross-section of the end plate 3 is larger than the size of the top cross-section of the lattice column 2, and a plurality of stiffening ribs 8 which are arranged at intervals and surround in a circle are fixedly connected between the area where the bottom of the end plate 3 does not contact the lattice column 2 and the outside of the lattice column 2.

[0032] By welding a circle of stiffening ribs 8 between the bottom of the end plate 3 and the side of the lattice column 2, the connection firmness between the end plate 3 and the lattice column 2 can be improved, making the force stable.

[0033] Among them, referring to Figure 1As shown, a plurality of first stiffening plates 7 that are fixedly connected to the outside of each first anchoring end 402 and enclose a circle to form an inverted corbel structure, and the bottoms of the plurality of first stiffening plates 7 are fixedly connected to the top of the corresponding end plate 3;

[0035] By providing the first stiffening plates 7, the anchoring firmness between the heavy tower crane embedment part 4 and the concrete pile cap 1 can be improved, and by providing the second stiffening plates 9, the anchoring firmness between the light tower crane embedment part 6 and the concrete pile cap 1 can be improved, thereby enhancing the strength of the shared tower crane foundation structure.

[0036] Among them, the fixing member 5 can be an angle steel.

[0037] By setting the fixing member 5 as an angle steel as the connecting stress-bearing member, it has good strength and weldability, and can be welded to the first anchoring end 402 in practical applications to improve the strength of the concrete pile cap 1.
