Description

Technical Field

[0001] This utility model relates to the field of level measurement technology, and in particular to a level measuring device for building construction. Background Technology

[0002] In the construction of building projects, leveling is a core and fundamental process. Its accuracy directly determines the stability of the building structure, the accuracy of component installation, and the construction quality of subsequent decoration work. Whether it is foundation excavation, main structure masonry, floor leveling, or pipeline installation, all stages have stringent requirements for the accuracy of the horizontal benchmark. As modern building projects develop towards high-rise, complex, and sophisticated directions, traditional leveling devices have gradually revealed many problems with their adaptability and can no longer meet the current demands for efficiency and high precision in engineering construction.

[0003] Construction sites are complex environments where factors such as wind, personnel movement, and construction machinery operation can all cause vibration interference. Furthermore, the unreasonable distribution of the device's center of gravity fails to effectively counteract the impact of external vibrations on the measurement benchmark, leading to misjudgments by detection elements such as the level bubble and further reducing measurement accuracy. In addition, existing devices rely on a limited range of methods for horizontal detection, often depending solely on the level bubble for qualitative judgment. This allows for only a rough prediction of the horizontal state and cannot accurately quantify the tilt angle of the measurement plane. In complex terrain and space-constrained construction areas, both the detection accuracy and adaptability to different scenarios are significantly lacking. Utility Model Content

[0004] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide a level measuring device for building construction. This device solves the problems of difficulty in controlling the accuracy and low efficiency of level measurement in building construction. It uses a rotating block to drive a bevel gear transmission screw, allowing the adjusting rod to slide in conjunction with the scale of the support rod for precise measurement control. Combined with a spirit level, it quickly levels the support base. It also solves the problems of poor balance and susceptibility to vibration and swaying in the support structure. A slider drives a connecting rod to achieve synchronous opening of the support rod, a rubber pad fixes the slider, and a load-bearing frame is used to counteract external interference. Furthermore, it solves the problem of insufficient measurement accuracy in complex building construction scenarios. Through the dual guarantee of spirit level-assisted prediction and precise measurement by a level instrument, it improves the accuracy of plane levelness and tilt angle measurement.

[0005] This utility model also provides a building construction level measuring device, comprising: a support base, a level instrument provided on the upper surface of the support base, a support rod rotatably connected to the side surface of the support base, a screw rod rotatably connected to the inner side wall of the support rod, an adjusting rod threadedly connected to the side surface of the screw rod, and a support foot fixedly connected to the end of the adjusting rod away from the screw rod.

[0006] A central rod is fixedly connected to the lower surface of the support base. A slider is slidably connected to the side surface of the central rod. A connecting rod is rotatably connected to the side surface of the slider. A rotating rod is rotatably connected to the inner side of the connecting rod. An extension rod is slidably connected to the inner side wall of the rotating rod. A fixed end is rotatably connected to the end of the extension rod away from the rotating rod. The surface of the fixed end is in contact with a load-bearing frame during operation. Through these components, the slider drives the connecting rod to make each support rod open synchronously at the same angle. The rubber pad increases friction to fix the slider and ensures the balance of the support. The load-bearing frame directly below the center can be loaded with heavy objects, using the center of gravity to offset vibrations caused by wind, personnel movement, etc., and reduce device swaying.

[0007] According to the present invention, a level measuring device for building construction includes a threaded rod rotatably connected to the upper surface of a load-bearing frame, and the side surface of the threaded rod is threadedly connected to a fixed end. The load-bearing frame is mounted on the fixed end via the threaded rod.

[0008] According to the present invention, in a building construction level measuring device, the end of the connecting rod away from the slider is rotatably connected to the support rod, and the side surface of the adjusting rod is slidably connected to the support rod. Sliding the slider causes the support rod to open via the connecting rod.

[0009] According to the present invention, a level measuring device for building construction includes a rotating block rotatably connected to the side surface of a support rod, and a drive bevel gear fixedly connected to one end of the rotating block near the support rod. The rotating block drives the drive bevel gear to rotate.

[0010] According to the present invention, a level measuring device for building construction includes a driven bevel gear meshing with the side surface of a driving bevel gear, and the surface of the driven bevel gear being fixedly connected to a screw. The driving bevel gear drives the driven bevel gear and the screw to rotate.

[0011] According to the present invention, in a building construction level measuring device, the surface of the driving bevel gear is rotatably connected to the support rod, and the surface of the driven bevel gear is also rotatably connected to the support rod. This allows the driving and driven bevel gears to rotate inside the support rod.

[0012] According to the present invention, a level measuring device for building construction includes a rubber pad fixedly connected to the inner side wall of the slider, and the inner side of the rubber pad slidably connected to the central rod. The rubber pad increases the friction between the slider and the central rod.

[0013] According to the present invention, a level measuring device for building construction includes a bubble level on the side surface of the support base, and the load-bearing frame is located directly below the central rod. The level is used to observe whether the support base is adjusted to be level.

[0014] Beneficial effects:

[0015] This technical solution's building construction leveling device uses a rotating block to drive a bevel gear transmission, which in turn drives a screw to slide an adjusting rod, changing the effective length of the support rod. Combined with the support rod's scale, the adjustment amount can be precisely controlled. The bubble level allows for rapid adjustment of the support base to a horizontal position, significantly improving measurement efficiency. The support structure boasts strong stability; the slider drives the connecting rod, enabling all support rods to open synchronously at the same angle. Rubber pads increase friction to fix the slider, ensuring support balance. A load-bearing frame directly below the center can be used to load heavy objects, using the center of gravity to offset vibrations caused by wind and personnel movement, reducing device sway. Dual leveling protection enhances measurement accuracy: the bubble level assists in predictive adjustment, and the level accurately measures the plane's levelness or tilt angle, making it suitable for complex building construction scenarios.

[0024] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0025] Reference Figure 1-5This utility model provides a level measuring device for building construction, which includes: a support base 1, a level 2 provided on the upper surface of the support base 1, a support rod 4 rotatably connected to the side surface of the support base 1, a screw 5 rotatably connected to the inner side wall of the support rod 4, an adjusting rod 6 threadedly connected to the side surface of the screw 5, a sliding connection between the side surface of the adjusting rod 6 and the support rod 4, and a support foot 7 fixedly connected to the end of the adjusting rod 6 away from the screw 5.

[0026] Specifically, when in use, the support rod 4 is opened so that it can support the support base 1 and the level 2 above it through the support feet 7. When the ground is uneven and the support base 1 tilts or the height of the support base 1 needs to be adjusted, the screw 5 can be turned to drive the adjusting rod 6 to slide along the support rod 4, thereby changing the effective length of the support rod 4, thereby changing the height of the support base 1 or adjusting the support base 1 to be horizontal. After completion, the levelness or tilt angle of the building is measured by the level 2.

[0027] A central rod 9 is fixedly connected to the lower surface of the support base 1. A slider 10 is slidably connected to the side surface of the central rod 9. A connecting rod 11 is rotatably connected to the side surface of the slider 10. The end of the connecting rod 11 away from the slider 10 is rotatably connected to the support rod 4. A rotating rod 13 is rotatably connected to the inner side surface of the connecting rod 11. An extension rod 14 is slidably connected to the inner side wall of the rotating rod 13. A fixed end 15 is rotatably connected to the end of the extension rod 14 away from the rotating rod 13. The surface of the fixed end 15 is in contact with the load-bearing frame 12 during operation.

[0028] Specifically, during the opening of the support rod 4, the slider 10 slides along the central rod 9, and the connecting rod 11 around the slider 10 drives the support rod 4 to open, so that the support rod 4 can rotate at the same angle. After adjustment, the rotating rod 13 on the connecting rod 11 can be rotated, and the extension rod 14 can be slid according to actual needs, so that the load frame 12 can be placed on the fixed end 15 at the end of the extension rod 14. Sandbags, buckets filled with water, and other objects with low center of gravity and regular shape can be placed in the load frame 12 to improve the anti-interference ability, counteract the vibration caused by wind and personnel movement, reduce device shaking, and make the reading of the level 2 more stable. Since the rotation angle of the connecting rod 11 is the same and the size of the load frame 12 is fixed, the fixed load frame 12 can be located directly below the central rod 9, so that the center of gravity of the weight is also located at the center of the device.

[0029] A rotating block 8 is rotatably connected to the side surface of the support rod 4. A driving bevel gear 17 is fixedly connected to one end of the rotating block 8 near the support rod 4. The surface of the driving bevel gear 17 is rotatably connected to the support rod 4. A driven bevel gear 18 meshes with the side surface of the driving bevel gear 17. The surface of the driven bevel gear 18 is rotatably connected to the support rod 4. The surface of the driven bevel gear 18 is fixedly connected to the screw rod 5.

[0030] Specifically, when adjusting the effective length of the support rod 4, the rotating block 8 outside the support rod 4 can be rotated, which drives the driven bevel gear 18 and the screw 5 to rotate through the active bevel gear 17, thereby causing the adjusting rod 6 to slide along the support rod 4. The support rod 4 is also marked with a scale, which can be used to determine the distance the adjusting rod 6 has moved.

[0031] A threaded rod 16 is rotatably connected to the upper surface of the load-bearing frame 12. The side surface of the threaded rod 16 is threadedly connected to the fixed end 15. A rubber pad 19 is fixedly connected to the inner side wall of the slider 10. The inner side surface of the rubber pad 19 is slidably connected to the center rod 9. A spirit level 3 is provided on the side surface of the support seat 1. The load-bearing frame 12 is located directly below the center rod 9.

[0032] Specifically, the load-bearing frame 12 is provided with three threaded rods 16 for connecting to three fixed ends 15, so that the load-bearing frame 12 can be fixed between the three connecting rods 11. After adjustment, it can be positioned directly below the central rod 9. Weights are placed inside to improve the stability of the device. The inner side of the slider 10 is provided with a rubber pad 19 to increase the friction between the slider 10 and the central rod 9. The support base 1 is also provided with a bubble level 3 to observe whether the support base 1 is in a horizontal state, so as to facilitate adjustment according to the bubble level 3 and improve the accuracy of the level 2 measurement.

[0033] Working principle: First, unfold the support structure and slide the slider 10 along the central rod 9. The connecting rod 11 connected to the slider 10 drives the support rod 4 to open synchronously at the same angle, so that the support feet 7 at the end of the support rod 4 stably support the support base 1 and the upper level 2. The rubber pad 19 on the inner side of the slider 10 increases the friction with the central rod 9 and fixes the position of the slider 10 to keep the support rod in the open state. Then, adjust the level and height by observing the bubble level 3 on the side surface of the support base 1. If the support base 1 is tilted or the height needs to be adjusted, rotate the rotating part on the side of the support rod 4. Moving block 8 drives the active bevel gear 17 to mesh with the driven bevel gear 18, driving the screw 5 to rotate. This causes the threaded adjusting rod 6 to slide along the support rod 4, changing the effective length of the support rod until the spirit level 3 indicates a horizontal position. To reinforce stability, rotating rod 13 on connecting rod 11 is rotated, and sliding extension rod 14 is slidably adjusted to change its length. The load-bearing frame 12 is fixed to the fixed end 15 via threaded rod 16, with the load-bearing frame 12 positioned directly below the center rod 9. Sandbags or other heavy objects are placed inside the frame to counteract vibrations and reduce device swaying. Finally, the levelness or tilt angle of the building plane is measured using the level 2 on the support base 1.

[0034] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
