Description

Technical Field

[0001] This utility model belongs to the field of building engineering technology, and in particular relates to a scaffolding for building engineering. Background Technology

[0002] Construction scaffolding is an indispensable temporary facility in construction, mainly composed of uprights, horizontal bars, diagonal braces, and footboards. It is assembled into a stable frame structure using couplers or connectors, providing a safe working platform for workers and supporting material transportation and storage. Based on its purpose, it can be divided into structural construction scaffolding, decoration scaffolding, etc. Based on its erection method, it can be divided into ground-mounted, cantilevered, and climbing types. Materials are mostly steel pipes (such as Q235 steel), aluminum alloy, or bamboo and wood. Its design must strictly comply with standards such as the "Safety Technical Specification for Construction Coupler-Type Steel Pipe Scaffolding" (JGJ130) to ensure load-bearing capacity, stability, and anti-overturning performance. Combined with safety nets, guardrails, and other protective measures, it is a key technical equipment for ensuring safety at heights and improving construction efficiency. Modern engineering also utilizes intelligent monitoring systems to monitor the scaffolding status in real time, further strengthening construction safety management.

[0003] For example, Chinese patent CN219281201U discloses a scaffolding for construction engineering, relating to the field of construction engineering technology. It includes a support frame with a load-bearing plate mounted on its top. Limiters are installed around the support frame. The load-bearing plate includes an installation frame, with folding plates movably connected inside the installation frame. The folding plates are fixed together by a rotating shaft. Both ends of the rotating shaft at one end are rotatably connected to the inner wall of the installation frame. A fixing plate is fixedly connected to the top surface of the other end of the folding plate. A first screw is threaded through the middle of one side of the fixing plate, with a clamping plate fixedly connected to one end of the first screw. Sliding rods are threaded through one side of the fixing plate near both ends, with the other end of each sliding rod fixedly connected to one side of the clamping plate. This utility model achieves a simple structure and convenient installation. It allows for rapid assembly during scaffolding installation, reducing the time wasted in assembling the load-bearing plate, improving laying efficiency, and increasing the practicality of the equipment.

[0004] The above-mentioned patent has the following problems: In actual use, it does not have the function of adjusting the bottom support of the scaffold, which makes the scaffold very prone to tilting when encountering uneven settlement of the foundation, which is not conducive to the use of workers. In view of this, we propose a scaffold for construction engineering. Utility Model Content

[0005] The purpose of this utility model is to provide a scaffold for construction projects to solve the problems mentioned in the background art.

[0006] In view of this, the present invention provides a scaffold for construction engineering, including a scaffold body, wherein a shell is fixedly connected to the four corners of the bottom of the scaffold body, a movable block is provided inside the four shells, and a threaded sleeve is rotatably installed on the bottom of the inner wall of each of the four shells. Four support blocks are provided, with the tops of the four support blocks fixedly connected to the bottoms of the four movable blocks. Each of the four support blocks has a mounting groove at its bottom, and a pressure sensor is fixedly installed on the bottom of the inner wall of each of the four mounting grooves. Four sets of rotating components are respectively installed inside the four housings and are used to drive the four threaded sleeves to rotate. Four sets of limiting components are respectively disposed inside the four housings and are used to limit the movement of the four blocks respectively.

[0007] In this technical solution, the main body of the scaffold is first placed on the construction site. At this time, the four support blocks will be in contact with the ground. The load of the four support blocks will be monitored by four pressure sensors, and the load data will be transmitted to the display screen.

[0008] When the four load data are inconsistent, turn the corresponding handle, which will then drive the shaft and worm gear to rotate. Due to the meshing connection between the worm gear and the worm wheel, the rotation of the worm gear will drive the worm wheel to rotate, and the worm wheel will cause the threaded sleeve to rotate. The threaded rod moves up and down inside the threaded sleeve, thereby causing the moving block to lift and lower the support block. When the moving block lifts and lowers, the slider slides in the groove, thereby limiting the moving block and ensuring its stability during movement. The movement of the moving block will drive the support block to move. When the load data of the four support blocks are consistent, stop turning the handle, and the support block will be fixed at the current height. Through the above structure, the load of the four support blocks at the bottom of the scaffold body can be made consistent, solving the problem of uneven foundation settlement and avoiding the tilting of the scaffold body caused by local settlement, which could lead to injury to the workers on the scaffold body, and thus facilitating the use of the scaffold body.

[0009] In the above technical solution, furthermore, each of the four threaded sleeves is internally threaded with a threaded rod, and the bottom of each of the four threaded rods is fixedly connected to the top of the moving block.

[0010] In this technical solution, the rotation of the threaded sleeve can drive the threaded rod and the moving block to move.

[0011] In the above technical solution, furthermore, a display screen is fixedly installed on one side of each of the four housings, and the display screen is electrically connected to the pressure sensor.

[0012] In this technical solution, the load data monitored by the pressure sensor can be transmitted to the display screen via the display screen and the pressure sensor, making it convenient for staff to view.

[0013] In the above technical solution, the limiting component further includes four sliding grooves, which are respectively formed in four groups on the inner wall of the housing. Slider blocks are fixedly connected to all four sides of the moving block, and the four slider blocks are slidably installed inside the four sliding grooves.

[0014] In this technical solution, the slider slides in the groove, thereby limiting the movement of the moving block and ensuring the stability of the moving block during movement. The movement of the moving block can drive the support block to move.

[0015] In the above technical solution, the rotating component further includes a worm gear, which is fixedly sleeved on the outside of the threaded sleeve. A worm is rotatably installed on one side of the inner wall of the housing, and the worm and the worm gear are meshed together.

[0016] In this technical solution, since the worm and worm wheel are meshed together, the rotation of the worm can drive the worm wheel to rotate, and the worm wheel can cause the threaded sleeve to rotate.

[0017] In the above technical solution, a rotating shaft is rotatably mounted on one side of the housing, and one side of the rotating shaft extends into the interior of the housing. The end of the rotating shaft located inside the housing is fixedly connected to the worm gear.

[0018] In this technical solution, the handle and the worm gear can be connected by a set rotating shaft.

[0019] In the above technical solution, a handle is further fixedly connected to one end of the rotating shaft located outside the housing, and the handle is made of rubber.

[0020] In this technical solution, the use of a rubber handle improves the comfort of workers when turning the handle.

[0021] The beneficial effects of this utility model are: 1. First, place the main body of the scaffolding on the construction site. At this time, the four support blocks will be in contact with the ground. The load of the four support blocks will be monitored by the four pressure sensors, and the load data will be transmitted to the display screen.

[0022] 2. When the four load data are inconsistent, turn the corresponding handle, which will then drive the shaft and worm gear to rotate. Due to the meshing connection between the worm gear and the worm wheel, the rotation of the worm gear will drive the worm wheel to rotate, causing the threaded sleeve to rotate. The threaded rod moves up and down inside the threaded sleeve, thereby raising and lowering the moving block along with the support block. When the moving block rises and falls, the slider slides in the groove, thus limiting the moving block and ensuring its stability during movement. The movement of the moving block will drive the support block to move. When the load data of the four support blocks are consistent, stop turning the handle. At this time, the support block will be fixed at the current height. Through the above structure, the load of the four support blocks at the bottom of the scaffold body can be made consistent, solving the problem of uneven foundation settlement and avoiding the tilting of the scaffold body caused by local settlement, which could lead to injury to the workers on the scaffold body. This also makes it easier for workers to use the scaffold. Attached Figure Description

[0025] The following is in conjunction with the appendix Figure 1 - Figure 5 This application will be described in further detail.

[0026] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," and "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0027] Example 1: This example provides a scaffold for construction engineering, including a scaffold body 1, with a shell 2 fixedly connected to the four corners of the bottom of the scaffold body 1, a movable block 5 provided inside each of the four shells 2, and a threaded sleeve 3 rotatably installed on the bottom of the inner wall of each of the four shells 2. Four support blocks 6 are provided, and the tops of the four support blocks 6 are fixedly connected to the bottoms of the four movable blocks 5 respectively. Each of the four support blocks 6 has a mounting groove 9 at its bottom, and a pressure sensor 10 is fixedly installed on the bottom of the inner wall of each of the four mounting grooves 9 (it is hereby noted that the pressure sensor 10 in this application is a product manufactured by Honeywell with the model number SSCMRRN005PG2A3). Four sets of rotating components are respectively installed inside the four housings 2 and are used to drive the four threaded sleeves 3 to rotate. Four sets of limiting components are respectively installed inside the four housings 2, and are used to limit the four moving blocks 5 respectively.

[0028] First, the main body 1 of the scaffold is placed on the construction site. At this time, the four support blocks 6 will be in contact with the ground. The load of the four support blocks 6 will be monitored by the four pressure sensors 10, and the load data will be transmitted to the display screen 15.

[0029] When the four load data are inconsistent, turn the corresponding handle 14, which will then drive the rotating shaft 13 and worm 12 to rotate. Since the worm 12 and worm wheel 11 are meshed, the rotation of the worm 12 will drive the worm wheel 11 to rotate. The worm wheel 11 will cause the threaded sleeve 3 to rotate, and the threaded rod 4 will move up and down inside the threaded sleeve 3, thereby allowing the moving block 5 to lift and lower the support block 6. When the moving block 5 lifts and lowers, the slider 8 slides in the groove 7, thereby limiting the moving block 5 and ensuring the stability of the moving block 5 during movement. The movement of the moving block 5 will drive the support block 6 to move. When the load data of the four support blocks 6 are consistent, stop turning the handle 14. At this time, the support block 6 can be fixed at the current height. Through the above structure, the load of the four support blocks 6 at the bottom of the scaffold body 1 can be made consistent, which solves the problem of uneven settlement of the foundation and avoids the tilting of the scaffold body 1 caused by local settlement, which could lead to injury to the workers on the scaffold body 1. This also makes it more convenient for workers to use.

[0030] Example 2: This example provides a scaffold for construction engineering. In addition to the technical solution of the above example, it also has the following technical features: the interior of each of the four threaded sleeves 3 is threaded with a threaded rod 4, and the bottom of each of the four threaded rods 4 is fixedly connected to the top of the moving block 5.

[0031] The rotation of the threaded sleeve 3 can drive the threaded rod 4 and the moving block 5 to move.

[0032] Example 3: This example provides a scaffold for construction engineering. In addition to the technical solutions of the above examples, it also has the following technical features: a display screen 15 is fixedly installed on one side of each of the four housings 2, and the display screen 15 is electrically connected to the pressure sensor 10.

[0033] The load data monitored by the pressure sensor 10 can be transmitted to the display screen 15 via the display screen 15 for easy viewing by staff.

[0034] Example 4: This example provides a scaffold for construction engineering. In addition to the technical solutions of the above examples, it also has the following technical features: the limiting component includes four sliding grooves 7, which are respectively opened in four groups on the inner wall of the housing 2. The moving block 5 is fixedly connected to the four sides of the sliding block 8, and the four sliding blocks 8 are respectively slidably installed inside the four sliding grooves 7.

[0035] The slider 8 slides within the groove 7, thereby limiting the movement of the moving block 5 and ensuring its stability during movement. The movement of the moving block 5 can drive the support block 6 to move.

[0036] Example 5: This example provides a scaffold for construction engineering. In addition to the technical solutions of the above examples, it also has the following technical features: the rotating component includes a worm gear 11, which is fixedly sleeved on the outside of the threaded sleeve 3. A worm 12 is rotatably installed on one side of the inner wall of the housing 2, and the worm 12 is meshed with the worm gear 11.

[0037] Since the worm 12 and the worm wheel 11 are meshed together, the rotation of the worm 12 can drive the worm wheel 11 to rotate, and the worm wheel 11 can cause the threaded sleeve 3 to rotate.

[0038] Example 6: This example provides a scaffold for construction engineering. In addition to the technical solutions of the above examples, it also has the following technical features: a rotating shaft 13 is rotatably installed on one side of the shell 2, and one side of the rotating shaft 13 extends into the interior of the shell 2. The end of the rotating shaft 13 located inside the shell 2 is fixedly connected to the worm gear 12.

[0039] The handle 14 can be connected to the worm gear 12 via the pivot 13.

[0040] Example 7: This example provides a scaffold for construction engineering. In addition to the technical solutions of the above examples, it also has the following technical features: a handle 14 is fixedly connected to one end of the pivot 13 located outside the housing 2. The handle 14 is made of rubber.

[0041] The rubber handle 14 improves the comfort of workers when turning it.

[0042] Working principle: First, the main body 1 of the scaffold is placed on the construction site. At this time, the four support blocks 6 will be in contact with the ground. The load of the four support blocks 6 will be monitored by the four pressure sensors 10. The load data will be transmitted to the display screen 15.

[0043] When the four load data are inconsistent, turn the corresponding handle 14, which will then drive the rotating shaft 13 and worm 12 to rotate. Since the worm 12 and worm wheel 11 are meshed, the rotation of the worm 12 will drive the worm wheel 11 to rotate. The worm wheel 11 will cause the threaded sleeve 3 to rotate, and the threaded rod 4 will move up and down inside the threaded sleeve 3, thereby allowing the moving block 5 to lift and lower the support block 6. When the moving block 5 lifts and lowers, the slider 8 slides in the groove 7, thereby limiting the moving block 5 and ensuring the stability of the moving block 5 during movement. The movement of the moving block 5 will drive the support block 6 to move. When the load data of the four support blocks 6 are consistent, stop turning the handle 14. At this time, the support block 6 can be fixed at the current height. Through the above structure, the load of the four support blocks 6 at the bottom of the scaffold body 1 can be made consistent, which solves the problem of uneven settlement of the foundation and avoids the tilting of the scaffold body 1 caused by local settlement, which could lead to injury to the workers on the scaffold body 1. This also makes it more convenient for workers to use.
