Description

Tower crane anchor frame

technical field

The utility model relates to a fixing frame for the foundation foot of a tower crane, which is especially suitable for working conditions that do not need to use standard joints or foundation joints to ensure the level and verticality of the fixed support feet.

Background technique

The fixed foot of the tower crane is a steel structure that is pre-buried in the concrete and can be connected to the foundation section or standard section of the tower body after the concrete is hardened. During the foundation pouring process, the fixed feet must be installed symmetrically according to the center line of the concrete foundation, and installed in a square according to the cross-sectional size of the tower body. At the same time, the fixed feet need to be connected with the foundation section or standard section through the foot fixing frame, and then poured concrete. In the existing structural design, the structure of the anchor frame is double-connected, as shown in Figure 1 and Figure 2. The anchor frame is a transitional structure connecting the anchor and the standard section during the foundation pouring process. To ensure the levelness requirements of the plane on the fixed feet, a plumb line or a level can be used for testing. After the concrete is hardened, the standard section of the tower body is allowed to be removed.

Since during the foundation pouring process, the fixed foot must be connected with the foundation section or standard section through the foot fixing frame, and then the concrete is poured, and the size, section and strength requirements of the standard section of the tower body are different. The fixed frame structure has poor site applicability and low efficiency. Moreover, the anchor fixing frame must not only ensure the relative position accuracy requirements of the four fixed feet, but also ensure the matching accuracy requirements with the foundation section or standard section, and in the production process, two tailor-welded frocks are required to ensure The design requirements of the structure, one guarantees the matching accuracy requirements with the fixed feet, and the other guarantees the matching accuracy requirements with the foundation section or standard section. Therefore, the manufacturing process of this structural form is complicated, the size of the tooling is large and complex, the production cycle is long, and the labor cost and time cost are high.

Contents of the invention

Aiming at the above-mentioned existing technical problems, the utility model provides a tower crane foot fixing frame, so as to improve the efficiency and practicality of the fixing frame in construction site construction, and reduce manufacturing difficulty and cost.

In order to achieve the above purpose, the utility model provides a tower crane foot fixing frame, which includes four vertical legs with the top surface flush and four horizontal frames. The middle parts of two adjacent vertical legs are connected by a cross frame to form a square structure corresponding to the cross-sectional size of the tower body; and the upper ends of two adjacent vertical legs are connected by at least one horizontal beam, and the opposite two horizontal beams are connected by at least one horizontal beam. Beam connection. Remove the matching parts with the standard section, and according to the size, section and strength requirements of the standard section of the tower body, increase its overall corresponding height and strength to meet the design requirements.

Preferably, the horizontal beam is a channel steel beam; the inclined beam is an angle steel beam.

The utility model has the following advantages: 1. The new fixed frame of the foundation retains the connection between the lower end of the original structure and the fixed foot, but does not need the connection and cooperation of the standard section or the foundation section, so that the level and verticality of the foundation can be guaranteed. By increasing the appropriate overall structural height and strength, it replaces the need to use standard joints or foundation joints to ensure the level and verticality of the fixed feet during the foundation pouring process, greatly reducing the foundation production time and corresponding labor costs.

2. The structure design is humanized, which improves the efficiency and practicality of the construction site construction of the anchor frame.

3. Simplify the production process, reduce a large number of related dimensions that need to be guaranteed by tooling, and the production is simple and the cycle is short, reducing the difficulty and cost of production.

Detailed ways

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

As shown in Fig. 3 and Fig. 4, the utility model comprises four vertical legs 6 and four horizontal frames 7 with the top surfaces flush, and the lower end of each vertical leg 6 is provided with a joint fitting part 2 connected with a fixed leg, and the adjacent The middle parts of the two vertical legs 6 are connected by a cross frame 7 to form a square structure corresponding to the cross-sectional size of the tower body; and the upper ends of two adjacent vertical legs 6 are connected by at least one horizontal beam 4, and the opposite two horizontal beams 4 The connection is via at least one inclined beam 5 .

In the above embodiment, the horizontal beam 4 is a channel steel beam.

In the above embodiments, the inclined beam 5 is an angle steel beam.

The lower end of this structure is the same as the structure of the existing anchor frame, that is, the lower end is kept flush with the four main limbs at the upper end of the fixed leg connection and matching part 2, and the connection and matching part 1 with the standard joint is removed, and an appropriate amount of level is increased. The beam 4 is used to improve the structural strength, and the oblique beam 5 is added to prevent its deformation. According to the size, section and strength requirements of the standard section of the tower body, its overall corresponding height is increased to meet the design requirements.

By applying this technology, the anchor frame of XGTT200(6022) improves the efficiency and practicability of its construction site construction. It does not need the connection and cooperation of standard joints or foundation joints, which can not only ensure the level and verticality of the foundation, but also meet the It reduces the complexity of the foundation pouring process (it does not need to be completed in conjunction with the standard section), reduces its production difficulty and cost, greatly shortens the pouring time, meets the requirements of humanized design, and achieves good application results. The technology has a wide range of applications and strong versatility, and can be applied to pin-type chip-type standard sections of different interfaces: L46A1 (1.6×1.6×3.0m), L68B1 (2.0×2.0×3.0m), etc.
