Abstract
Description
Technical Field
[0001] This utility model relates to the field of building settlement observation technology, specifically to a building settlement observation device. Background Technology
[0002] As building heights and loads increase, uneven settlement inevitably occurs due to the complex interaction between the foundation and superstructure. Mild settlement may lead to tilting or cracks, affecting the building's functionality; severe settlement can directly threaten the overall structural safety, even causing collapses or other major accidents. To effectively address this issue, current building codes mandate systematic settlement monitoring for the foundations of tall structures, high-rise buildings, and continuous production facilities. This monitoring allows for a comprehensive understanding of building deformation and related information, enabling in-depth analysis of deformation patterns and reasonable prediction of future deformation levels. This allows for timely and effective preventative measures or proper post-construction management, ensuring the building's safe and stable operation. Specifically, settlement monitoring involves periodically measuring the elevation of settlement monitoring devices embedded in the building. The elevation changes between these devices determine parameters such as settlement and tilt, allowing for the assessment of the impact of settlement deformation on the building's structural integrity and providing data for preventative or post-construction measures.
[0003] Currently, settlement monitoring devices mainly employ horizontal or L-shaped observation rods. These rods are fixed to the exterior walls of buildings, allowing the use of measuring tools such as levels to measure their elevation and determine data such as building settlement and tilt. However, because the portion of the observation rod extending beyond the wall is constantly exposed to the external environment, it is easily susceptible to corrosion from the natural environment or human damage, which can adversely affect the accuracy and stability of the rod, thus impacting the accuracy of the building settlement data. To address this issue, settlement monitoring devices are designed to be concealed. These devices are pre-embedded within the building's wall. When observation is needed, the end of the observation rod is manipulated to protrude from the wall to meet the requirements. After the measurement is completed, the rod is retracted into the wall for protection. However, operating observation rods at such heights is extremely cumbersome for tall structures and high-rise buildings. Furthermore, to facilitate the protrusion of the observation rod from the wall, it is difficult to completely seal and embed the rod within the wall, leaving it exposed to the external environment and susceptible to various corrosive factors. Therefore, the settlement monitoring device has shortcomings in terms of ease of operation and protective function. Improvements to the settlement monitoring device are needed to facilitate operation of the observation rod and enhance its protective effect, thereby meeting the requirements for building settlement monitoring.

[0005] The technical solution adopted by this utility model is as follows: a building settlement observation device, comprising a box with an open bottom and a cover at the open end of the box. An observation rod is disposed inside the box, and the observation rod contacts the inner wall of one side of the box. A groove is opened at one end of the box, and the observation rod is movably fitted into the groove. The cross-sectional shape of the groove matches the cross-sectional shape of the observation rod. A sleeve is disposed on the observation rod, and the sleeve is installed on one end of the observation rod. A push rod is disposed on the side of the sleeve away from the observation rod. A connecting rod is disposed between the push rod and the sleeve, and the two ends of the connecting rod are respectively... The device is hinged to a push rod and a sleeve. A rotating shaft is provided on the push rod, and a sleeve hole is provided on the box body. The rotating shaft is movably fitted into the sleeve hole. A rotating cap is provided at one end of the rotating shaft that extends out of the sleeve hole. The diameter of the rotating cap is not less than the diameter of the sleeve hole. The two ends of the rotating shaft are respectively installed on the rotating cap and the push rod. A sealing plate is provided on the outside of the sleeve groove. A first hinge is provided on the sealing plate. The two sides of the first hinge are respectively installed on the top surface of the box body and the side of the sealing plate away from the box body. A fixing groove is provided in the box body above the sleeve groove. A spring is provided in the fixing groove. The two ends of the spring are respectively installed on the box body and the sealing plate.
[0006] Preferably, an observation block is provided on the side of the observation rod away from the sleeve, the side of the observation block is in contact with the end face of the observation rod, a second hinge is provided above the observation block, the two sides of the second hinge are respectively installed on the end face of the observation rod and the top surface of the observation block, and a guide groove is provided on the side of the observation block near the observation rod, the guide groove is located below the observation rod, and the length of the guide groove gradually increases along the direction away from the observation rod.
[0007] Preferably, the box body is provided with a pad, which is installed at the top of the inner cavity of the box body. A limiting groove is opened on one side of the pad, and the upper middle part of the observation rod is located in the limiting groove. The inner cavity shape of the limiting groove matches the shape of the upper middle part of the observation rod. The top end of the sleeve and the top end of the push rod are in contact with the pad respectively. A through hole is opened on the pad, and the rotating shaft is movably fitted in the through hole. The diameter of the through hole matches the diameter of the rotating shaft.
[0008] Preferably, a fixing frame is provided on the side of the rotating cap away from the sealing plate. The fixing frame is installed on the box body, and the box cover is movably fitted inside the fixing frame. Several fixing holes are provided on the fixing frame.
[0009] Preferably, the push rod has two support holes, which are respectively located at both ends of the push rod, and the rotating shaft is fixedly fitted into one of the support holes; the connecting rod is provided with two hinge rods, which are respectively installed at both ends of the connecting rod, and the two hinge rods are respectively fitted into the other support hole and the sleeve, and the diameter of the hinge rod matches the inner diameter of the support hole and the sleeve.

[0012] The beneficial effects of this utility model are as follows: First, the utility model creates a protective environment for the observation rod through the box body and box cover. The first engagement spring in the box body causes the sealing plate to adhere tightly to the box body, thereby sealing the slot on the box body and protecting the observation rod inside, preventing external corrosion and improving the protective effect. Furthermore, the utility model uses a sleeve, push rod, and connecting rod, along with the inner wall of the box body and the slot, to constrain the observation rod, converting rotation into movement of the observation rod. By rotating the shaft, one side of the observation rod can extend or retract from the box body, simplifying the operation of the observation rod. A rotating cap on the shaft allows a tool to rotate the shaft; therefore, using a long-rod tool to rotate the cap satisfies the requirements for moving the measuring rod.
[0013] Secondly, this invention uses a second hinge to hinge the observation block to the side of the observation rod away from the sleeve, allowing the use of measuring tools such as a level to obtain relevant data such as elevation and inclination of the observation block, thereby determining the settlement and inclination of the building. A guide groove on the observation block facilitates its movement into the housing. Furthermore, the included pad not only constrains the observation rod to reduce swaying during movement but also constrains the rotating shaft, push rod, and sleeve, thus improving the stability of their operation.
[0014] Furthermore, this invention utilizes a fixed frame and fixing holes on the frame to install the frame onto the wall using anchor nails, thereby assembling the box onto the wall. Moreover, this invention employs sealing rings and sealing collars to seal the gaps between the sealing plate and the box, as well as between the rotating cap and the box, thereby improving the protection of the box's internal cavity.

[0021] like Figures 1 to 6As shown, a building settlement monitoring device includes a box 1 with an open bottom and a cover 2 at the open end of the box 1. An observation rod 3 is installed inside the box 1, contacting the inner wall of one side of the box 1. A groove 4 is provided at one end of the box 1, and the observation rod 3 is movably fitted into the groove 4. The cross-sectional shape of the groove 4 matches the cross-sectional shape of the observation rod 3, so as to constrain the movement of the observation rod 3. A sleeve 5 is provided on the observation rod 3, installed at one end of the observation rod 3. A push rod 6 is provided on the side of the sleeve 5 away from the observation rod 3. A connecting rod 7 is provided between the push rod 6 and the sleeve 5. The connecting rod 7, push rod 6, and sleeve 5 are all located inside the box 1. The ends are respectively hinged to the push rod 6 and the sleeve 5. The push rod 6 is provided with a rotating shaft 8. The housing 1 has a sleeve hole 9. The rotating shaft 8 is movably fitted into the sleeve hole 9. The diameter of the sleeve hole 9 matches the diameter of the rotating shaft 8. A rotating cap 10 is provided at one end of the rotating shaft 8 that extends out of the sleeve hole 9. The diameter of the rotating cap 10 is not less than the diameter of the sleeve hole 9. The two ends of the rotating shaft 8 are respectively installed on the rotating cap 10 and the push rod 6. Preferably, the rotating cap 10 has a hexagonal cross-section so that a tool with a hexagonal inner cavity can be used to screw the rotating cap 10, thereby pushing the rotating cap 10, the rotating shaft 8 and the push rod 6 to rotate together, thereby driving the connecting rod 7 to rotate, and using the inner wall of the housing 1 and the sleeve groove 4 opened in the housing 1 to adjust the observation rod 3. The sleeve 5 and the observation rod 3 are moved by pushing and pulling the rotating connecting rod 7, so that one side of the observation rod 3 extends out of the box 1 or retracts into the box 1 for observation of the side of the observation rod 3 extending out of the box 1. Normally, the observation rod 3 is retracted into the box 1 for protection. The box cover 2 is installed on the open end of the box 1, and the bottom end of the observation rod 3 and the bottom end of the connecting rod 7 respectively contact the top surface of the box cover 2. Since the observation rod 3 contacts the inner wall of one side of the box 1, the rotation space of the push rod 6 and the connecting rod 7 is constrained. Therefore, during the rotation of the rotating cap 10, after the push rod 6 abuts against the inner wall of one side of the box 1, it is difficult to rotate the rotating cap 10 in the same direction. This indicates that the rotation of the cap 10 is complete, allowing the observation rod 3 to extend or retract. A sealing plate 11 is provided on the outer side of the sleeve groove 4, and a first hinge 12 is provided on the sealing plate 11. The two sides of the first hinge 12 are respectively installed on the top surface of the box body 1 and the side of the sealing plate 11 away from the box body 1. The sealing plate 11 is hinged to the box body 1 via the first hinge 12. A fixing groove 13 is provided on the box body 1 above the sleeve groove 4, and a spring 14 is provided inside the fixing groove 13. The two ends of the spring 14 are respectively installed on the box body 1 and the sealing plate 11. Using the elasticity of the spring 14, the sealing plate 11 is pulled tightly against the box body 1, thereby sealing the sleeve groove 4 and the fixing groove 13 to improve the protection of the observation rod 3.
[0022] In this embodiment, an observation block 15 is provided on the side of the observation rod 3 away from the sleeve 5. The lower middle part of the observation block 15 is located below the observation rod 3, and the side of the observation block 15 is in contact with the end face of the observation rod 3. A second hinge 16 is provided above the observation block 15. The two sides of the second hinge 16 are respectively installed on the end face of the observation rod 3 and the top surface of the observation block 15. The observation block 15 is hinged to the observation rod 3 through the second hinge 16. The width of the observation block 15 is not greater than the width of the observation rod 3, so that the observation block 15 can pass through the sleeve groove 4, so that the observation rod 3 can pull the observation block 15 into the box 1, thereby using the box 1 to protect the observation block 15. A guide groove 17 is provided on the side of the observation block 15 near the observation rod 3. The guide groove 17 is located below the observation rod 3, and the length of the guide groove 17 gradually increases along the direction away from the observation rod 3, so that the observation rod 3 can pull the observation block 15 into the box 1.
[0023] Specifically, a pad 18 is provided inside the box body 1. The pad 18 is installed at the top of the inner cavity of the box body 1. A limiting groove 19 is opened on one side of the pad 18. The upper middle part of the observation rod 3 is located in the limiting groove 19. The inner cavity shape of the limiting groove 19 matches the shape of the upper middle part of the observation rod 3 to improve the constraint effect of the observation rod 3, thereby reducing the shaking during the movement of the observation rod 3. The top of the sleeve 5 and the top of the push rod 6 are in contact with the pad 18, respectively. The bottom end of the sleeve 5 and the bottom end of the push rod 6 are in contact with the top of the connecting rod 7, respectively. A through hole 20 is opened on the pad 18. The rotating shaft 8 is movably fitted in the through hole 20. The diameter of the through hole 20 matches the diameter of the rotating shaft 8, so as to constrain the rotating shaft 8, the push rod 6 and the sleeve 5, thereby improving the stability of the rotating shaft 8, the push rod 6 and the sleeve 5 in use.
[0024] Please refer to it again. Figures 1 to 3 The rotating cap 10 is provided with a fixing frame 21 on the side away from the sealing plate 11. The fixing frame 21 is installed on the box body 1. The box cover 2 is movably fitted inside the fixing frame 21. The fixing frame 21 is provided with a number of fixing holes 22. The fixing frame 21 is fixed to the wall by passing the fixing holes 22 through the anchor nails, so that the fixing frame 21 can be fixed to the wall, and then the product can be assembled on the wall.
[0025] In this embodiment, the push rod 6 has two support holes 23, which are respectively located at both ends of the push rod 6. The rotating shaft 8 is fixedly fitted into one of the support holes 23. The connecting rod 7 is provided with two hinge rods 24, which are respectively installed at both ends of the connecting rod 7. Both hinge rods 24 are located above the connecting rod 7. The two hinge rods 24 are respectively fitted into the other support hole 23 and the sleeve 5. The diameter of the hinge rod 24 matches the inner diameter of the support hole 23 and the sleeve 5. The connecting rod 7 is hinged to the push rod 6 and the sleeve 5 through the two hinge rods 24.
[0026] Specifically, the sealing plate is provided with a sealing ring 25 made of elastic material. The sealing ring 25 is installed on the side of the sealing plate 11 near the box body 1. The sealing ring 25 contacts the outer wall of the box body 1 to seal the gap between the sealing plate 11 and the box body 1, so as to improve the protection effect on the inner cavity of the box body 1.
[0027] Please refer to it again. Figure 1 , 3 5. A sealing ring 26 made of elastic material is fitted on the rotating shaft 8. The inner diameter of the sealing ring 26 is not greater than the diameter of the rotating cap 10. The two sides of the sealing ring 26 are in contact with the rotating cap 10 and the box body 1 respectively, thereby sealing the gap between the rotating cap 10 and the box body 1 and preventing rainwater, dust and other impurities from entering the box body 1 through the sleeve hole 9.
[0028] The assembly method for this product is as follows: (e.g.) Figures 1 to 6 As shown, based on factors such as the overall structural layout of the building, construction information, and current project progress, multiple installation locations are selected for the building. Then, slots are cut at the selected installation locations so that the side of the box 1 and box cover 2 furthest from the observation block 15 is inserted into the slot, bringing the fixing frame 21 into contact with the building wall. Next, appropriate anchoring nails are passed through the fixing holes 22 on the fixing frame 21 to secure it to the building wall, thus clamping and fixing the fixing frame 21 to the building wall for quick assembly. It should be noted that the orientation of the rotating cap 10 needs to be adjusted according to the overall structure of the building; if the installation location is close to the ground, adjust the rotating cap 10 to face the ground. Conversely, if the installation location is close to the top of the building, adjust the rotating cap 10 to face the top of the building for rotation.
[0029] When using this product for observation, firstly, place the long, narrow tool that matches the structure of the rotating cap 10 on the side of the rotating cap 10 away from the box 1, so that the long, narrow tool can be inserted into the rotating cap 10, preparing for the subsequent rotation operation. Next, insert the long, narrow tool into the rotating cap 10 and rotate it to drive the rotating cap 1, the rotating shaft 8, and the push rod 6 to rotate together, thereby driving the connecting rod 7 to rotate. The inner wall of the box 1 and the slot 4 opened in the box 1 constrain the observation rod 3, so that the rotating connecting rod 7 can be used to push and pull the sleeve 5, the observation rod 3, and the observation block 15 to move, so that one side of the observation block 15 and the observation rod 3 protrudes from the box 1, so that the elevation of the observation block 15 and the observation rod 3 can be measured using measuring tools such as a level. After the observation work is completed, use the long, narrow tool again, insert it into the rotating cap 10, and rotate it in the opposite direction to control the observation block 15 and the observation rod 3 to retract into the box 1.
[0030] In this embodiment, the box body 1 and the box cover 2 create a protective environment for the observation rod 3. The first hinge 12 and the spring 14 on the box body 1 cause the sealing plate 11 to be tightly attached to the box body 1, thereby sealing the slot 4 on the box body 1. This provides enclosed protection for the observation rod 3 inside the box body 1, preventing it from being corroded by the outside environment and improving the protective effect of the observation rod 3. Moreover, this utility model uses the sleeve 5, push rod 6, and connecting rod 7, and the inner wall of the box body 1 and the slot 4 on the box body 1 to constrain the observation rod 3, so that the rotation of the rotating shaft 8 is converted into the movement of the observation rod 3. By rotating the rotating shaft 8, one side of the observation rod 3 can be moved out of or back into the box body 1, thus simplifying the operation of the observation rod 3. The rotating cap 10 on the rotating shaft 8 allows the rotating shaft 8 to be rotated by a tool. Therefore, using a tool with a long rod structure to rotate the rotating cap 10 can meet the requirements of moving the measuring rod 3.
[0031] The embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the patent claims of this utility model should be included within the scope of the patent application of this utility model.
