Description

Technical Field

[0001] This utility model relates to the field of foundation settlement observation technology, specifically a foundation settlement observation scale. Background Technology

[0002] In building construction, foundation settlement is a key factor affecting the stability and safety of buildings. Accurate monitoring of foundation settlement is crucial for timely detection of potential problems and the implementation of appropriate measures. Commonly used methods for foundation settlement monitoring include leveling and GPS surveying, and the performance of the settlement monitoring rod, as an important tool in leveling, directly affects the accuracy and reliability of the observation data.

[0003] Currently, existing foundation settlement observation scales have some shortcomings in practical use: the scales are mostly installed by directly fixing them to the ground, which makes them prone to tilting due to factors such as differences in the initial flatness of the foundation and vibrations from surrounding construction. Furthermore, existing scales lack convenient verticality calibration mechanisms, making it difficult to ensure the verticality accuracy of the measurement benchmark, which directly leads to systematic deviations in the observation data. Therefore, it is urgent to design a foundation settlement observation scale to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a foundation settlement observation scale to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A foundation settlement observation scale includes a support cylinder, a guide rod fixed at the middle of the top inner wall of the support cylinder, a guide sleeve slidably disposed on the outer wall of the guide rod, a movable cylinder sleeved on the outer wall of the guide sleeve and fitted outside the guide rod, and a pre-embedded plate fixedly installed at the bottom of the movable cylinder, measuring components disposed on the outer wall of the movable cylinder and the outer wall of the support cylinder, a universal level fixedly installed on the top of the support cylinder, and verticality adjustment components evenly distributed on the outer wall of the support cylinder.

[0007] Furthermore, the measuring component includes a movable groove formed on the support cylinder, and a movable seat extending out of the movable groove is fixed to the top of the outer wall of the movable cylinder. A guide rod is fixedly installed at one end of the movable seat, and a scale line is provided on the outer wall of the support cylinder, the position of the scale line corresponding to the position of the guide rod.

[0008] Furthermore, the verticality adjustment component includes support seats evenly spaced around the support cylinder, and a threaded column is rotatably connected to the top of the support seat. A knob is fixed to the top of the threaded column. A lifting seat is screwed to the outer wall of the threaded column, and multiple connecting seats are fixed to the outer wall of the support cylinder. A movable rod is rotatably connected between the lifting seat and the connecting seats via a pin.

[0009] Furthermore, a limiting hole is provided at the top of the support base, and a limiting rod inserted into the limiting hole is fixed at the bottom of the lifting base.

[0010] Furthermore, positioning sleeves are fixed to the bottom of both sides of the support base, and positioning screws are installed on the inner wall of the positioning sleeves.

[0011] Furthermore, the inner wall of the guide sleeve is provided with multiple rows of equally spaced balls, and the balls are attached to the outer wall of the guide rod.

[0012] Furthermore, an anti-detachment disc is fixed to the bottom of the guide rod, and the outer diameter of the anti-detachment disc is smaller than the inner diameter of the movable cylinder.

[0013] Furthermore, a handle is fixedly installed on the top of the outer wall of the support cylinder.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In this invention, by setting a sliding fit structure between the guide rod and the guide sleeve, precise guidance can be provided for the lifting and lowering movement of the movable cylinder relative to the support cylinder, reducing the interference of shaking on the measurement; while the ball bearing design on the inner wall of the guide sleeve further reduces the friction during the sliding process, ensuring smoother movement of the movable cylinder as the foundation settles, avoiding measurement errors caused by jamming, and allowing the overall structure to maintain stable motion performance during long-term use.

[0016] In this invention, the movable seat in the measuring component drives the guide rod to move along the movable groove, and in conjunction with the scale lines on the outer wall of the support cylinder, it can intuitively and accurately reflect the amount of foundation settlement, and realize the direct reading of settlement data.

[0017] In this invention, the universal level at the top of the support cylinder can monitor in real time whether the scale is horizontal. At the same time, the knob in the verticality adjustment component drives the threaded column to rotate, causing the lifting seat to rise and fall. Then, the movable rod pushes the support cylinder to adjust the verticality. Thus, with the cooperation of multiple verticality adjustment components distributed at equal distances, the support cylinder can be finely adjusted from different directions, ensuring that the scale can quickly reach a vertical state even in complex foundation environments. This solves the problem that existing scales cannot guarantee the verticality accuracy of the measurement benchmark due to the lack of convenient adjustment mechanisms. It provides a benchmark reference for measurement, effectively avoids measurement deviations caused by device tilting, and greatly improves the reliability of observation data.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-5In this embodiment of the utility model, a foundation settlement observation scale includes a support cylinder 1. A guide rod 9 is fixed at the middle of the inner top wall of the support cylinder 1, and a guide sleeve 12 is slidably provided on the outer wall of the guide rod 9. A movable cylinder 7, sleeved outside the guide rod 9, is fixed on the outer wall of the guide sleeve 12. An embedded plate 8 is fixedly installed at the bottom of the movable cylinder 7. A measuring component is provided on the outer wall of the movable cylinder 7 and the outer wall of the support cylinder 1. The measuring component includes a movable groove 4 opened on the support cylinder 1, and a movable seat 10 extending from the movable groove 4 is fixed on the top of the outer wall of the movable cylinder 7. A guide rod 11 is fixedly installed at one end of the movable seat 10, and a scale line 5 is provided on the outer wall of the support cylinder 1. The position of the scale line 5 corresponds to the position of the guide rod 11. The movable seat 10 in the measuring assembly drives the guide rod 11 to move along the movable groove 4, and in conjunction with the scale line 5 on the outer wall of the support cylinder 1, it can intuitively and accurately reflect the foundation settlement and realize the direct reading of settlement data. A universal level 2 is fixedly installed at the top of the support cylinder 1. The universal level 2 monitors in real time whether the scale is in a horizontal state, providing a benchmark reference for measurement. The outer wall of the support cylinder 1... A verticality adjustment assembly 6 is provided, which includes a support base 64 evenly distributed around the support cylinder 1. A threaded post 67 is rotatably connected to the top of each support base 64. A knob 610 is fixed to the top of each threaded post 67. A lifting seat 63 is screwed to the outer wall of the threaded post 67. Multiple connecting seats 61 are fixed to the outer wall of the support cylinder 1. A movable rod 62 is rotatably connected to the lifting seat 63 and the connecting seats 61 via a pin. A limit hole 69 is provided at the top of each support base 64, and a rod inserted into the limit hole is fixed at the bottom of each lifting seat 63. The limiting rod 68 inside 69 and the bottom of both sides of the support base 64 are fixed with positioning sleeves 66, and the inner wall of the positioning sleeves 66 is equipped with positioning screws 65. If it is necessary to adjust the verticality of the entire scale, turn the knob 610 to drive the threaded column 67 to rotate, so that the lifting seat 63 rises and falls along the threaded column 67. The limiting rod 68 at the bottom of the lifting seat 63 slides along the limiting hole 69 on the support base 64. The lifting seat 63 pushes the connecting seat 61 through the movable rod 62, thereby adjusting the verticality of the support cylinder 1. The cooperation of multiple verticality adjustment components 6 ensures that the support cylinder 1 is in a vertical state.

[0026] Specifically, the inner wall of the guide sleeve 12 is provided with multiple rows of equally spaced balls 13, and the balls 13 are attached to the outer wall of the guide rod 9. The balls 13 reduce the friction during the sliding process, ensuring that the movable cylinder 7 moves more smoothly as the foundation settles, and avoiding measurement errors caused by jamming.

[0027] Specifically, the bottom of the guide rod 9 is fixed with an anti-detachment disc 14, and the outer diameter of the anti-detachment disc 14 is smaller than the inner diameter of the movable cylinder 7 to prevent the movable cylinder 7 from detaching from the entire scale.

[0028] Specifically, a handle 3 is fixedly installed on the top of the outer wall of the support cylinder 1, which facilitates the handling and movement of the device and improves the ease of use.

[0029] The working principle of this utility model is as follows: During installation, the support base 64 is fixed in a suitable position on the foundation by the positioning screws 65 in the positioning sleeves 66 on both sides of the support base 64, and the embedded plate 8 is connected to the foundation. Then, the support cylinder 1 is observed to be horizontal by the universal level 2. If the verticality needs to be adjusted, the knob 610 is turned to drive the threaded column 67 to rotate, so that the lifting seat 63 rises and falls along the threaded column 67. The limiting rod 68 at the bottom of the lifting seat 63 slides along the limiting hole 69 on the support base 64. The lifting seat 63 pushes the connecting seat 61 through the movable rod 62, thereby adjusting the verticality of the support cylinder 1. Multiple verticality adjustment components 6 work together to ensure that the support cylinder 1 is in a vertical state.

[0030] When the foundation settles, the embedded plate 8 drives the movable cylinder 7 to settle with the foundation. The movable cylinder 7 slides along the guide rod 9 through the guide sleeve 12. The ball bearings 13 in the guide sleeve 12 reduce sliding friction. During measurement, the movable cylinder 7 drives the movable seat 10 to move along the movable groove 4 on the support cylinder 1. The guide rod 11 at one end of the movable seat 10 corresponds to the scale line 5 on the outer wall of the support cylinder 1. The settlement amount is read by the change in the relative position of the scale line 5 and the guide rod 11.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
