Description

Technical Field

[0001] The utility model relates to the field of construction, in particular to a tower crane foundation support device. Background Art

[0002] The construction of the tower crane foundation is a key step in the subsequent installation of the tower crane. To ensure the verticality and stability of the tower crane in the later stage, the control of the elevation and levelness of the tower crane foundation is extremely important.

[0003] During the current construction process of the tower crane foundation, it is relatively common to use a jack to adjust the tower crane foundation frame. After the foundation frame is calibrated, a large number of support steel bars need to be welded to ensure the stability of the tower crane foundation frame.

[0004] However, the steel bar has a certain elastic deformation amount, and the jack needs to be removed. After removal, it is inevitable that the support steel bar will be deformed, which will affect the levelness of the foundation frame. At the same time, during the later concrete pouring process, the existing steel bar support may be displaced, thus affecting the overall stability, and improvement is needed. Summary of the Utility Model

[0005] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a tower crane foundation support device, which has the effect of improving stability.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: A tower crane foundation support device, comprising:

[0007] A support frame, which is arranged on the ground in a conical shape;

[0009] A lower support frame, which is arranged at the middle position of the support frame;

[0010] Support rods, which are vertically arranged on the upper support frame and the lower support frame, and the upper ends are located above the upper support frame;

[0011] A support plate, which is horizontally arranged at the upper end of the support rod and is used to connect the lower end of the tower crane.

[0012] In a preferred example of the utility model, it can be further configured that: adjusting nuts are arranged on both the upper support frame and the lower support frame, the support rod is a screw rod, and is threadedly connected to the adjusting nut.

[0013] In a preferred example of the utility model, it can be further configured that: both the upper support frame and the lower support frame include a frame and a plurality of steel rods, the plurality of steel rods are arranged in a cross shape, and the ends are fixed at the top corner positions of the frame.

[0014] In a preferred embodiment, the present utility model can be further configured as follows: a plurality of the steel rods are arranged in a horizontal and vertical grid pattern, and the end portions are fixed to the edge positions of the frame.

[0015] In a preferred embodiment, the present utility model can be further configured as follows: a plurality of reinforcing rods connected end to end are provided at the lower end of the support frame, and the reinforcing rods are fixed to the lower end of the support frame.

[0016] In a preferred embodiment, the present utility model can be further configured as follows: the support frame includes four support rods, and an adjustment tube is slidably connected to the lower end of each support rod, and a bolt for pressing the support rod is threadedly connected to the adjustment tube.

[0017] In summary, the present utility model has the following beneficial effects:

[0018] 1. By providing a support device with high stability, independent support for the four bottom feet positions of the tower crane is achieved. The support device is relatively stable and not prone to tipping, which can greatly reduce the use of foundation fixing steel bars and also reduce additional fixing welding measures.

[0024] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] Embodiment 1:

[0026] As Figure 1 shown, a tower crane foundation support device includes a support frame 1, an upper support 2, a lower support 3, a support rod 4, and a support plate 5.

[0027] As Figure 1 shown, the support frame 1 includes four support rods 11. The four support rods 11 are arranged in a conical shape on the ground. A plurality of reinforcing rods 12 connected end to end are provided at the lower ends of the four support rods 11. The reinforcing rods 12 are fixed to the lower ends of the four support rods 11 to ensure the load-bearing capacity of the support frame 1.

[0028] As Figure 1 shown, the upper support frame 2 is arranged at the upper end of the support frame 1, and the lower support frame 3 is arranged at the middle position of the support frame 1. Adjusting nuts 6 are provided on both the upper support frame 2 and the lower support frame 3.

[0029] As Figure 1 shown, the support rod 4 is vertically arranged on the upper support frame 2 and the lower support frame 3 and is threadedly connected to the adjusting nut 6. At the same time, the upper end of the support rod 4 is located above the upper support frame 2 to adjust the overall use height of the support rod 4. The support plate 5 is horizontally arranged at the upper end of the support rod 4 and is used to connect the lower end of the tower crane.

[0030] When using the support device, place the four support devices on the ground respectively, then rotate the support rod 4 according to the needs to adjust the height position of the support plate 5. Subsequently, use a level or an infrared measuring instrument to measure the levelness of the four support plates 5, and rotate the support rod 4 according to the measurement results to make the four support plates 5 belong to the same horizontal plane. Then install the tower crane so that the support plate 5 connects the tower crane. Finally, pour concrete to make the concrete wrap the entire support device.

[0031] Therefore, by setting a support device with high stability, independent support for the four bottom feet of the tower crane is achieved. The support device is relatively stable and not prone to tipping, which can greatly reduce the use of foundation fixing steel bars and also reduce additional fixing welding measures.

[0032] Compared with the jack support, this support device can reduce the fluctuation change of the overall tower crane foundation levelness caused by the disassembly process during use, ensuring the stability during the use process. At the same time, when pouring concrete, the support device is integrally arranged and can stably bear the load of the concrete without deviation or displacement, thus ensuring the overall stability of the support device.

[0033] Moreover, by setting the support rod 4 with adjustable height, it can adapt to different use requirements, improve practicability, and at the same time enable each support point at the bottom foot position of the tower crane to be adjusted separately, greatly ensuring the verticality of the subsequent tower crane.

[0034] As Figure 1As shown, the upper support 2 and the lower support 3 both include a frame 21 and a plurality of steel rods 22. The plurality of steel rods 22 are arranged in a cross shape and their ends are fixed at the top corner positions of the frame 21 to ensure the structural strength and load-bearing capacity of the support device and the stability during use.

[0035] Embodiment 2:

[0036] As Figure 2 shown, for a tower crane foundation support device, a plurality of steel rods 22 are arranged in a horizontal and vertical grid shape and their end positions are fixed at the edge positions of the frame 21 to ensure the structural strength and load-bearing capacity of the support device and the stability during use.

[0037] Embodiment 3:

[0038] As Figure 3 shown, for a tower crane foundation support device, a regulating pipe 13 is slidably connected to the lower end of each support rod 11, and a bolt 14 for pressing the support rod 11 is threadedly connected to the regulating pipe 13. Therefore, by adding a regulating pipe 13 to the lower end of the support rod 11, the levelness of the lower end of the support frame 1 is adjusted, the levelness of the entire support device is ensured, and thus the levelness and verticality after the tower crane is installed are ensured.
