[0002] With the increasing number of urban renewal projects, especially in large cities like Shanghai and Beijing, the restoration and renovation of cultural heritage buildings has become a crucial task. These projects typically require the preservation of the building's exterior walls while simultaneously rebuilding the internal structure. In this process, the arrangement of material transportation equipment becomes critical to project implementation. Traditional methods of arranging hoisting equipment, such as mobile cranes or tower cranes with reinforced concrete slab foundations, are often unsuitable for confined spaces. Particularly in cultural heritage projects, conventional concrete slab foundation tower crane foundations can collide with the surrounding walls, necessitating the demolition of these walls, which are within the protected cultural heritage area and therefore not feasible. Therefore, a new type of tower crane foundation platform device is needed that can effectively avoid collisions with protected walls in confined spaces and support the lifting and lowering of protected buildings.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0020] Please see Figure 1-5 One embodiment provided by this utility model:

[0021] A steel structure tower crane foundation platform device includes: a concrete column, supporting steel rods fixedly connected to the surface of the concrete column, a foundation platform top plate provided on the top of the supporting steel rods, a tower crane body fixedly installed on the surface of the foundation platform top plate, connecting crossbars fixedly connected to the surface of the supporting steel rods, a first reinforcing diagonal frame fixedly connected to the surface of the connecting crossbars, a connecting assembly fixedly connected to the surface of the foundation platform top plate, a supporting assembly fixedly connected to the surface of the supporting steel rods, a first connecting steel rod fixedly connected to the surface of the connecting assembly, a second connecting steel rod fixedly connected to the surface of the supporting assembly, a supporting steel frame fixedly connected to the surface of the concrete column, and supporting blocks fixedly connected to the surface of the supporting steel frame. The system features a fixed second reinforcing diagonal brace, with a reinforcing crossbar fixedly connected to the top of the second reinforcing diagonal brace. The concrete columns are installed using a casting method, while the supporting steel rods are inserted into the concrete columns during casting, thus fixing the supporting steel rods to the concrete columns. The remaining fixed connections on the supporting steel rods are all spliced ​​using high-strength bolts. This steel structure tower crane foundation platform device has an overall grid-like steel structure, avoiding the use of concrete slab foundations. It can raise the top plate of the foundation platform to a height exceeding that of the courtyard wall, ensuring the installation and use of the tower crane body and preventing the top plate of the foundation platform from colliding with the courtyard wall. This effectively solves the problem of collision between the tower crane foundation platform device and the cultural relic protection wall in a confined space, saving construction space.

[0022] Furthermore, the concrete columns are cast into the ground, and four sets of concrete columns and supporting steel rods are set up. The four sets of concrete columns support the four sets of supporting steel rods in the ground. The bottom of the supporting steel rods is located underground, which ensures the stability of the concrete columns supporting the supporting steel rods on the ground. The top of the supporting steel rods is higher than the height of the courtyard wall.

[0023] Furthermore, the connecting crossbars and supporting steel bars are perpendicular to each other, and the first reinforcing diagonal frame is in the shape of an "X". Multiple sets of connecting crossbars and the first reinforcing diagonal frame are provided and are arranged crosswise on the surface of the supporting steel bars. The connecting crossbars and the first reinforcing diagonal frame connect the four sets of concrete columns, so that the supporting steel bars, connecting crossbars, and the first reinforcing diagonal frame form a whole, thereby facilitating the support of the top plate of the foundation platform.

[0024] Furthermore, the connecting components are fixedly connected to the top of the supporting steel rods. The connecting components are in an "L" shape. The top plate of the foundation platform is fixedly installed on the top of the concrete column through the connecting components. There are four sets of connecting components. The surface of the top plate of the foundation platform is provided with insertion slots. The connecting components are inserted into the insertion slots of the top plate of the foundation platform. The connecting components fix the top plate of the foundation platform on the top of the four sets of supporting steel rods.

[0025] Furthermore, the first connecting steel rod is in an "X" shape, and its bottom is fixedly connected to the surface of the support assembly. The second connecting steel rod is in a "V" shape. The first and second connecting steel rods together form a scissor shape on the support steel rod, and both the first and second connecting steel rods are located on the ground. The first and second connecting steel rods can effectively connect to the support steel rods on the ground, ensuring the strength of the four sets of support steel rods on the ground.

[0026] Furthermore, the supporting steel rods support the supporting steel frame through connecting crossbars, and the supporting steel frame supports the second reinforcing diagonal bar and the reinforcing crossbar. The second reinforcing diagonal bar is in an overall "X" shape. The supporting steel frame and the second reinforcing diagonal bar are located between multiple sets of supporting steel rods, and the reinforcing crossbar and the supporting steel rods are perpendicular to each other.

[0027] Furthermore, the first connecting steel rod and the reinforcing crossbar are fixedly connected, and the second reinforcing diagonal rod provides diagonal support to the first connecting steel rod through the reinforcing crossbar. The second reinforcing diagonal rod and the reinforcing crossbar strengthen the connection between the four sets of supporting steel rods through the first connecting steel rod.

[0028] Working principle: Four sets of concrete columns are poured underground. Four sets of supporting steel rods are then installed at the bottom of the concrete columns. High-strength bolts are used to fix the connecting crossbars and the top plate of the foundation platform between the four sets of supporting steel rods. The top plate of the foundation platform is then fixed to the top of the four sets of supporting steel rods using connecting components. At this point, the supporting steel frame is fixed to the surface of the connecting crossbars using high-strength bolts. The second connecting steel rod is then fixed to the supporting components and support blocks using high-strength bolts. The first connecting steel rod is then fixed to the connecting components and supporting components using high-strength bolts. Finally, the second reinforcing diagonal brace is fixed to the supporting components using high-strength bolts. Finally, the reinforcing crossbar on the second reinforcing diagonal bar is fixed to the surface of the first connecting steel rod with high-strength bolts. At this point, the steel structure tower crane foundation platform device is installed and the whole structure is a lattice steel structure. Then, the tower crane body is fixed to the surface of the top plate of the foundation platform with high-strength bolts. This steel structure tower crane foundation platform device avoids the use of concrete slab foundations and can raise the top plate of the foundation platform to a height exceeding that of the courtyard wall, ensuring the installation and use of the tower crane body and preventing the top plate of the foundation platform from colliding with the courtyard wall. This effectively solves the problem of collision between the tower crane foundation platform device and the cultural relic protection wall in a narrow space and saves construction space.
