Description

Technical Field

[0001] This utility model relates to the field of foundation pit support technology, specifically to a deep foundation pit support control device for super high-rise buildings. Background Technology

[0002] When supporting a super high-rise building in a deep foundation pit, it is necessary to spray concrete on the surface of the pit to prevent the pit from collapsing. In conventional foundation pit spraying, the thickness of the sprayed concrete is controlled by using short soil nails at a height outside the soil. However, this process requires inserting short soil nails into the foundation pit first and then installing steel bars. Due to the large weight of the steel bars themselves and the tendency of the soil to sink, the thickness is difficult to control.

[0003] After searching, it was found that application number CN202122189079.5, entitled "A Device for Controlling the Thickness of Shotcrete for Foundation Pit Support," proposes a device that uses a threaded sleeve to connect to a threaded rod in the soil insertion part. Rotating the threaded sleeve controls the length outside the soil. After the reinforcing bars are pre-fixed using the first and second fixing parts, the weight of the reinforcing bars can easily cause soil subsidence, leading to the reinforcing bars settling and making it difficult to control the thickness during concrete pouring. At this point, the threaded sleeve can be rotated again to adjust the reinforcing bars to the predetermined height, making the thickness easier to control during concrete pouring. However, in practical use, due to the large volume of sprayed concrete and the wide coverage area, multiple sets of this device need to be installed, and each set needs to be adjusted individually, making it quite cumbersome. Furthermore, the device, inserted into the sidewall of the foundation pit, can damage the pit sidewall and cause intrusion. It is also not recyclable, resulting in significant waste. Further improvements are needed.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0010] Furthermore, a limiting plate is fixedly connected to the other end of the inner rod, and the outer edge of the limiting plate slides against the inner groove.

[0011] Furthermore, a rod groove is provided at the other end of the inner groove, and the size of the rod groove is larger than the size of the inner rod, while the size of the rod groove is smaller than the size of the limiting plate.

[0012] Furthermore, the first control lever and the second control lever are arranged coaxially, and both the first control lever and the second control lever are made of metal structures that are not easily deformed.

[0013] Furthermore, both the first and second collars have handle bolts threaded through their outer surfaces, and multiple sets of these bolts are arranged on each collar.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, this utility model provides a support and control device for deep foundation pits of super high-rise buildings, which has the following beneficial effects:

[0019] (1) This utility model adopts a first control rod and a second control rod. When carrying out concrete spraying construction for foundation pit support, the first support rod is installed on the top surface of the foundation pit through the first pin, and the second support rod is installed on the bottom surface of the foundation pit through the second pin. The first control rod and the second control rod are located on the outer side of the inner wall of the foundation pit. The bottom surface of the first control rod and the second control rod is the thickness of the concrete spraying. The thickness of the concrete spraying is controlled by the first control rod and the second control rod. During use, there is no need to install a control structure on the inner wall surface of the foundation pit, thus avoiding damage to the inner wall of the foundation pit. At the same time, when spraying concrete, the workers can move the first control rod and the second control rod along the first support rod and the second support rod according to the change of the concrete spraying position.

When it is necessary to adjust the overall spray thickness, the operator can adjust the position of the first and second pins simultaneously from left to right, thereby changing the distance between the first and second control rods and the inner wall of the pit and adjusting the thickness control value. When it is necessary to adjust the spray thickness of the upper or lower part of the pit, the operator can adjust the position of the first and second pins separately. At this time, the first and second control rods rotate along the rotating pins at both ends, and the inner rod extends and retracts along the inner groove, so that the spray control thickness can present the characteristics of thinner at the top and thicker at the bottom or thicker at the top and thinner at the bottom. There are various adjustment methods. The operator only needs to move the first and second pins to complete the adjustment. The adjustment is very simple. At the same time, the first and second pins installed on the top and bottom surfaces of the pit reduce the interference to the side wall of the pit, protect the stability of the pit support surface, and improve work efficiency.

[0029] According to an embodiment of the present invention, a support control device for deep foundation pits of super high-rise buildings is provided.

[0030] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4As shown, the building super high-rise deep foundation pit support control device according to an embodiment of the present invention includes a first support rod 1 and a second support rod 11. A first collar 2 is sleeved on the outer side of the first support rod 1, and a first crossbeam 5 is fixedly connected to one side surface of the first collar 2. The other end of the first crossbeam 5 is rotatably connected to a first control rod 7 via a rotating pin 6. A second collar 12 is rotatably sleeved on the outer surface of the second support rod 11, and a second crossbeam 14 is fixedly installed on one side surface of the second collar 12. The other end of the second crossbeam 14 is rotatably connected to a second control rod 10 via a rotating pin 6. An inner rod 9 is fixedly connected to the other end of the second control rod 10. An inner groove 8 is opened inside the other end of the first control rod 7, and the inner rod 9 is inserted into the inner groove 8. First pins 3 are fixedly connected to both ends of the first support rod 1, and first pins 3 are fixedly connected to the bottom surface of the second support rod 11. During the concrete spraying construction of the foundation pit support, the first support rod 1 is installed on the top surface of the foundation pit through the first pin 3, and the second support rod 11 is installed on the bottom surface of the foundation pit through the second pin 13. The first control rod 7 and the second control rod 10 are located on the outer side of the inner wall of the foundation pit. The bottom surface of the first control rod 7 and the second control rod 10 is the thickness of the concrete spraying. The thickness of the concrete spraying is controlled by the first control rod 7 and the second control rod 10. During use, there is no need to install control structures on the inner wall surface of the foundation pit, avoiding damage to the inner wall of the foundation pit. At the same time, when spraying concrete, the workers can move the first control rod 7 and the second control rod 10 along the first support rod 1 and the second support rod 11 according to the change of the concrete spraying position. They are reusable and can be repeatedly recycled, which significantly improves the convenience of use and reduces production costs.

[0031] In one embodiment, the other end of the inner rod 9 is fixedly connected to a limiting plate 15, and the outer edge of the limiting plate 15 slides against the inner groove 8 to improve the stability of the movement of the inner rod 9.

[0032] In one embodiment, a rod groove 16 is provided at the other end of the inner groove 8. The size of the rod groove 16 is larger than the size of the inner rod 9, and the size of the rod groove 16 is smaller than the size of the limiting plate 15. The rod groove 16 plays a limiting role to prevent the inner rod 9 from being completely pulled out of the inner groove 8.

[0033] In one embodiment, the first control lever 7 and the second control lever 10 are arranged coaxially, and both the first control lever 7 and the second control lever 10 are made of metal structures that are not easily deformed, so as to avoid errors caused by deformation.

[0034] In one embodiment, the outer surfaces of the first collar 2 and the second collar 12 are both threadedly connected with handle bolts 4, and multiple sets of handle bolts are arranged for each of the first collar 2 and the second collar 12. When the handle bolts 4 are rotated to tighten the first support rod 1 and the second support rod 11, the first collar 2 and the second collar 12 can be locked, thereby improving stability.

[0035] In one embodiment, two sets of the first pin 3 and the second pin 13 are arranged, and the bottom surfaces of the first pin 3 and the second pin 13 are provided with pointed tips to facilitate insertion into the soil on the top and bottom surfaces of the foundation pit.

[0036] In one embodiment, the bottom surfaces of the first collar 2 and the second collar 12 are both provided with through grooves, and the width of the through grooves is greater than the outer diameter of the first pin 3. Furthermore, the first pin 3 and the second pin 13 are the same size, which facilitates the direct removal and addition of the first collar 2 and the second collar 12 from both ends of the first support rod 1 and the second support rod 11, thereby further improving the flexibility of use.

[0037] In one embodiment, both the first support rod 1 and the second support rod 11 are made of metal round rods, which are common structures in the art and are stable and reliable.

[0038] Working principle:

[0039] During the shotcrete construction of the foundation pit support, the first support rod 1 is installed on the top surface of the foundation pit via the first pin 3, and the second support rod 11 is installed on the bottom surface of the foundation pit via the second pin 13. The first control rod 7 and the second control rod 10 are located on the outer side of the inner wall of the foundation pit, with the bottom surface of the first control rod 7 and the second control rod 10 representing the thickness of the shotcrete. The thickness of the shotcrete is controlled by the first control rod 7 and the second control rod 10. During use, there is no need to install control structures on the inner wall surface of the foundation pit, avoiding damage to the inner wall. Furthermore, during shotcreting, workers can move the first control rod 7 and the second control rod 10 along the first support rod 1 and the second support rod 11 according to changes in the shotcrete position. They are reusable and recyclable, significantly improving ease of use and reducing production costs. Additionally, when adjustments to the overall shotcrete thickness are needed... When adjusting the spray thickness, the operator can simultaneously adjust the positions of the first pin 3 and the second pin 13 to change the distance between the first control rod 7 and the second control rod 10 and the inner wall of the pit, thereby adjusting the thickness control value. When it is necessary to adjust the spray thickness of the upper or lower part of the pit, the operator can adjust the positions of the first pin 3 and the second pin 13 separately. At this time, the first control rod 7 and the second control rod 10 rotate along the rotating pins 6 at both ends, and the inner rod 9 extends and retracts along the inner groove 8, so that the spray thickness control can present the characteristics of thinner at the top and thicker at the bottom or thicker at the top and thinner at the bottom. There are multiple adjustment methods. The operator only needs to move the first pin 3 and the second pin 13 to complete the adjustment. The adjustment is very simple. At the same time, the first pin 3 and the second pin 13 installed on the top and bottom surfaces of the pit reduce the interference with the side walls of the pit, protect the stability of the pit support surface, and improve work efficiency.
