Description

Technical Field

[0001] This utility model belongs to the technical field of foundation pit maintenance devices, and particularly relates to a foundation pit maintenance device for building construction. Background Technology

[0002] Foundation pit maintenance refers to the protection of the pits formed during the excavation of the foundation in building construction. The pits created during foundation excavation, commonly known as the foundation itself, form the basis of the construction. The taller the building, the deeper the foundation. This makes the surrounding soil and rock prone to collapse. Therefore, we need to maintain the foundation pit and its slopes to prevent collapse or landslides that could affect construction.

[0003] Patent application number CN202322349200.5 discloses a construction foundation pit maintenance plate, including a base plate, a second baffle, and a baffle. A rib is fixedly installed on the front end face of the baffle, and the base plate is fixedly connected to the front end face of the baffle. A claw hook structure is installed on the upper end face of the base plate. A support structure is fixedly installed on the front end face of the baffle. The support structure includes a column, a fixing block, and a clamping plate. One end of the fixing block is fixedly installed on the front end face of the baffle, and the top end of the column is fixedly connected to the other end of the fixing block. The clamping plate is fixedly connected to the upper end face of the base plate by bolts. A conical angle is inserted into the soil, and then the hook plate is connected to the hook block, causing the solid shaft to descend and compress the spring, moving the support rod outward and opening the claw hook, greatly increasing the soil gripping area and further improving the stability of the device.

[0004] The existing technology enhances the stability of the foundation pit maintenance device by setting a base inside the foundation pit, setting baffles on the side, and setting a ground gripping mechanism below the base, but there are still many shortcomings in its overall use.

[0005] First, the foundation pit maintenance device is not permanently fixed and is usually disassembled after a certain period of time. However, the existing technology sets up a base to fix the maintenance device inside the foundation pit, which makes it inconvenient to disassemble when needed. In addition, rainwater may mix with soil and accumulate on the base during rainy weather, increasing the weight of the device during disassembly and increasing the workload of the staff.

[0006] Secondly, the maintenance of the foundation pit requires the splicing and assembly of multiple panels. If the panels are not completely sealed or are bent during splicing, it will affect the quality of the safety maintenance of the foundation pit. The existing equipment lacks the corresponding structure to detect whether the splicing is sealed and to determine whether the panels will be bent. Utility Model Content

[0007] To overcome the shortcomings of existing technologies, this utility model provides a foundation pit maintenance device for building construction. This application solves the problem of cumbersome disassembly and inability to quickly disassemble existing devices by incorporating a sealing detection block, fixing nails, and graduated grooves. The added structure enables the device to detect the sealing of connections and the quality of the sheet metal.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a foundation pit maintenance device for building construction, comprising an upper baffle, a side baffle rotatably disposed on one side of the upper baffle, a plurality of first fixing nails threadedly disposed on the upper baffle, a plurality of second fixing nails fixedly disposed on one side of the side baffle, a plurality of third fixing nails fixedly disposed on the lower end face of the side baffle, two cable take-up frames fixedly disposed on the side of the side baffle away from the second fixing nails, a turntable rotatably disposed inside the cable take-up frames, a rotating rope fixedly disposed on the lower end face of the upper baffle, and the rotating rope passing through the upper baffle and winding around the inside of the turntable.

[0009] Preferably, a plurality of anti-detachment rings are fixedly provided on the surface of the second fixing nail, and an anti-detachment groove is provided at the end of the anti-detachment ring near the side baffle.

[0010] Preferably, the tip of the first fixing pin is provided with a plurality of fixing grooves, and a threaded connecting post is provided on the side of the first fixing pin away from its tip.

[0011] Preferably, the turntable is provided with a wire take-up groove, and the wire take-up groove is provided with a wire clamping groove.

[0012] Preferably, connecting brackets are fixedly provided on both sides of the upper baffle and the side baffle, wherein one side of the connecting bracket is provided with multiple first threaded holes, and the other side of the connecting bracket is provided with multiple connecting through holes.

[0013] Preferably, a connecting block is fixedly provided on one side of the upper baffle and the side baffle, and a connecting groove is provided on the other side of the upper baffle and the side baffle. A sealing detection slider is slidably provided on the upper end surface of one side of the connecting frame.

[0014] Preferably, two reinforcing ribs are fixedly provided between the connecting frames on both sides of the side baffle end face, a scale plate is fixedly provided between the two connecting frames, and a scale groove is provided between the two reinforcing ribs on the upper baffle.

[0015] Preferably, a handle is fixedly provided between the two take-up frames.

[0016] In summary, compared with existing technologies, the beneficial effects of this solution are as follows: (1) This utility model, through the structure of the second fixing nail, the anti-detachment ring, the first threaded hole and the handle, ensures the stability of the device in the pit without setting a base. While effectively protecting the pit, it can be quickly disassembled by simply pulling it upwards. It can be quickly removed when needed for work.

[0017] (2) This utility model, through the structural design of connecting frame, sealing detection block, scale plate and connecting block, makes the connection between multiple devices simple and efficient. At the same time, it can check the sealing of the connection and whether the plate is bent, making the error of the plate installation visible, and can effectively reduce the risks caused by device quality and installation problems.

Detailed Implementation

[0028] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0029] Reference Appendix Figure 1 Appendix Figure 2 and attached Figure 5 A foundation pit maintenance device for a building includes an upper baffle 10. A rotating shaft 12 is fixedly installed on one side of the upper baffle 10. Both ends of the rotating shaft 12 extend out of the side walls of the upper baffle 10. Side baffles 11 are rotatably installed on the outside of both ends of the rotating shaft 12. Multiple second threaded holes 21 are provided on the end face of the upper baffle 10. First fixing nails 19 are threadedly connected inside the second threaded holes 21. Multiple inclined downward second fixing nails 23 are fixedly installed on one side of the side baffle 11. Multiple third fixing nails 26 are fixedly installed on the lower end face of the side baffle 11. Multiple anti-slip grooves 37 are provided on the end faces of the upper baffle 10 and the side baffle 11 that are close to each other. Two cable take-up frames 29 are fixedly installed on the side of the side baffle 11 away from the anti-slip grooves 37. A handle 38 is fixedly installed between the two cable take-up frames 29.

[0030] Specifically, when the excavation of the foundation pit is completed and it is not in use for the time being, the handle 38 can be held to bring the side end face of the side baffle 11 with the anti-slip groove 37 close to the side wall of the foundation pit. The side baffle is inserted and fixed at an angle downward towards the side wall of the foundation pit. During this process, multiple second fixing nails 23 on the side baffle 11 near the foundation pit will be driven into the soil on the side of the foundation pit at an angle downward, and the third fixing nail 26 will be driven into the soil at the bottom of the foundation pit. Then, the rotating shaft 12 is rotated to place the upper baffle 10 on the upper surface of the foundation pit. Since the upper surface of the foundation pit is not necessarily a horizontal surface, the rotation setting between the upper baffle 10 and the side baffle 11 through the rotating shaft 12 can make the device adapt to more types of foundation pits. Then, the first fixing nail 19 is driven into the soil on the upper side of the foundation pit through multiple second threaded holes 21 on the end face of the upper baffle 10, and the first fixing nail 19 is tightened at the same time. Since the second fixing nail 23 tends to penetrate downwards into the soil on the side of the pit, the side baffle 11 is less likely to fall off away from the side of the pit. Combined with the fixing effect of the first fixing nail 19 and the third fixing nail 26, the stability of the device can be further enhanced after installation.

[0031] More specifically, since the surface of the foundation pit is mostly uneven with grooves, the anti-slip grooves 37 provided on the upper baffle 10 and the side baffle 11 near the end face of the foundation pit can make the device fit the foundation pit surface better, increase the friction between the device and the foundation pit, and make the device more stable when in use.

[0032] Further, see attached document. Figure 7 and attached Figure 8The second fixing nail 23 has multiple anti-detachment rings 24 fixedly installed on its surface. The anti-detachment rings 24 have anti-detachment grooves 25 inside. The first fixing nail 19 has a pointed end that is driven into the soil. The pointed end has multiple fixing grooves 20 on its surface. The first fixing nail 19 has a threaded connecting post 22 with threads at its end away from the pointed end. The threaded connecting post 22 is threadedly connected to the second threaded hole 21 inside the upper baffle 10.

[0033] Specifically, during the process of the second fixing nail 23 being driven into the soil at an angle, the anti-detachment ring 24 will push the soil away from the second fixing nail 23 and then into the anti-detachment groove 25. At this time, if the second fixing nail 23 is pulled out away from the side of the foundation pit, the static friction between the second fixing nail 23 and the soil will increase, making the second fixing nail 23 less likely to be pulled out while ensuring stable driving. After the first fixing nail 19 is driven into the soil, the fixing groove 20 at its tip will also increase the static friction. At the same time, the threaded connection will also prevent workers or passers-by from accidentally pulling out the first fixing nail 19.

[0034] More specifically, the maintenance of the foundation pit is carried out by installing the upper baffle 10 and the side baffle 11 at the upper end and the side of the foundation pit. This method is convenient to install and easier to disassemble. When the staff needs to remove the device, they only need to use a crane or similar device to hook it onto the handle 38 and then pull it upwards, which saves the staff's workload.

[0035] Furthermore, the first fixing nail 19 is fixed by a threaded connection instead of being fixed to the bottom of the upper baffle 10, which makes it easier to install on the upper side of the pit. This avoids the upper surface of the pit from being dug out by the first fixing nail 19 due to the rotation of the upper baffle 10 during the installation of the device, thus affecting the stability of the upper baffle 10.

[0036] Furthermore, see the attached document. Figure 1 Appendix Figure 4 Appendix Figure 5 Appendix Figure 9 Two rotating ropes 27 are fixedly installed on the lower end face of the upper baffle 10, and two rope through holes 28 are provided on the end face of the side baffle 11. A groove is provided at the end of the take-up frame 29 away from the side baffle 11. A turntable 30 is rotatably installed in the groove. A take-up groove 31 is provided in the middle of the turntable 30. A wire-locking groove 32 for fixing the rotating ropes 27 is provided inside the take-up groove 31. After passing through the rope through holes 28, the rotating ropes 27 can be coiled in the take-up groove 31. A rocker arm 33 is fixedly installed on the side of the two turntables 30 that are far apart from each other.

[0037] Specifically, when installing the upper baffle 10, if the upper baffle 10 cannot be fully pressed against the outside of the upper end of the foundation pit without external force, the rocker arm 33 can be rotated. This allows the turntable 30 to rotate via the rocker arm 33. Since one end of the rotating rope 27 is fixed in the cable groove 32, the rotating turntable 30 can collect the rotating rope 27 in the cable take-up groove 31. This allows the upper baffle 10 to be pulled towards the side baffle, gradually pressing it against the upper side of the foundation pit for auxiliary fixing. In this design, a locking structure is installed on the outside of the rocker arm 33 during actual operation to fix the turntable 30 after it has finished winding, preventing it from flipping or loosening. In this design, when the upper baffle and side baffle are not in use, the turntable 30 and rotating rope 27 can also be tightened to make the two baffles fit together, reducing the overall volume and facilitating transportation.

[0038] Further, see attached document. Figure 1 , attached Figure 3 Appendix Figure 5 and attached Figure 6 A connecting frame 13 is fixedly provided on both sides of the upper baffle 10 and the side baffle 11. One side of the connecting frame 13 is provided with multiple first threaded holes 14, and the other side of the connecting frame 13 is provided with multiple connecting through holes 15. A sealing detection slider 18 is slidably provided on the upper end surface of one side of the connecting frame 13. A connecting block 16 is fixedly provided on one side of the upper baffle 10 and the side baffle 11. A sealing element is fixedly provided on the surface of the connecting block 16. A connecting groove 17 is provided on the other side of the upper baffle 10 and the side baffle 11. A sealing groove is provided inside the connecting groove 17.

[0039] Specifically, in actual use of the device, multiple devices are needed to maintain the foundation pit. At this time, the connecting brackets 13 of two devices can be fitted together, and then the threaded rod is passed through the connecting through hole 15 and threadedly connected to the connecting bracket 13. Tightening the threaded rod will fix the two devices together. At the same time, the connecting block 16 of one device is connected and engaged with the connecting groove 17 on the other device. The sealing element on the surface of the connecting block 16 will be embedded in the sealing groove inside the connecting groove 17 to achieve sealing.

[0040] More specifically, when connecting two devices, the seal detection slider 18 can be pulled out towards the other device first. After the connection is completed, the scale on the seal detection slider 18 can be observed to determine whether the two devices are completely sealed.

[0041] Further, see attached document. Figure 1 and attached Figure 2Two reinforcing ribs 34 are fixedly arranged between the two connecting brackets 13 on the surface of the side baffle 11. A scale groove 36 is provided between the two reinforcing ribs 34 on the side of the upper baffle 10 away from the second fixing nail 23. A scale plate 35 is fixedly arranged between the two connecting brackets 13 on the surface of the side baffle 11.

[0042] Specifically, when the side baffle 11 is subjected to excessive pressure from the foundation pit, it may deform. Workers can periodically check the scale plate 35 and scale groove 36 of the device. When the scale plate 35 and scale groove 36 change when observed with reference to the reinforcing rib 34, it proves that the device has deformed. At this time, it is necessary to replace the device or dismantle and start construction as soon as possible according to the actual situation.

[0043] Finally, it should be noted that the connection and fixing of each part of the foundation pit maintenance device for building construction of this utility model can be achieved by conventional mechanical connection structure, and the control system and connection method required between multiple electrical components and driving components can also be achieved by conventional means and can be equipped with corresponding sensors and detectors. As long as it can achieve its beneficial effect or the specific actions in the above work, it can be implemented.
