Description

Technical Field

[0001] This utility model relates to the field of building settlement monitoring technology, specifically to a building construction settlement monitoring device. Background Technology

[0002] To ensure the structural safety and normal service life of buildings, long-term settlement monitoring is required after the completion of construction projects. Settlement monitoring is mainly carried out in conjunction with observation instruments and settlement observation nails. During construction, multiple sets of L-shaped observation nails are pre-embedded and fixed at predetermined observation points on the exterior walls of the building. By periodically measuring the elevation data of the observation nails with observation instruments, the settlement changes of the building can be accurately grasped.

[0003] L-shaped settlement monitoring nails protrude from the wall surface and are easily displaced by external impacts, affecting the accuracy of settlement monitoring. Therefore, protective covers are usually installed on the outside of the monitoring nails for protection. Most protective covers on the market are fixed by drilling holes in the wall and using expansion bolts. However, once the expansion bolts are installed and tightened, they are basically single-use components. During disassembly, the expansion structure is very prone to jamming, deformation and damage, and cannot be reused.

[0004] When the protective cover is damaged or aged and needs to be replaced, the disassembly operation is not only difficult and time-consuming, but the original expansion bolts cannot be reinstalled after removal, and new fasteners need to be re-drilled and installed. The overall replacement and maintenance process is cumbersome, the operation and maintenance cost is high, and the flexibility of use is poor. In view of the above-mentioned defects of the existing technology, this case proposes a building construction settlement monitoring device. Utility Model Content

[0005] In view of the above situation and to overcome the shortcomings of the existing technology, this utility model provides a building construction settlement monitoring device.

[0006] The technical solution adopted by this utility model is as follows: This utility model provides a building construction settlement monitoring device, including a wall. An L-shaped observation nail is fixedly provided on the side wall of the wall. A settlement groove is opened on the side wall of the wall, and the L-shaped observation nail is located at the center of the settlement groove. A protective component is assembled inside the settlement groove. The protective component includes an annular shell and a protective cylinder. A locking unit is assembled on the annular shell and is fastened and fixed inside the settlement groove by the locking unit. The protective cylinder is threadedly connected to the annular shell. The L-shaped observation nail penetrates the annular shell and extends into the interior of the protective cylinder.

[0007] Furthermore, the locking units are evenly arranged along the circumference of the annular shell, and each locking unit includes a threaded rod and an expansion block. One end of the threaded rod is rotatably connected to the inner wall of one side of the annular shell via a bearing, and the other end is rotatably passed through the outer wall of the other side of the annular shell via a bearing and fixed to a knob. Each threaded rod is arranged parallel to the central axis of the annular shell. The threaded rod is externally threaded with a moving block, and the expansion block is slidably inserted through the circumferential side wall of the annular shell and is arranged in a one-to-one correspondence with the moving block. The end of the expansion block located on the inner side of the annular shell is provided with a first inclined surface, and the side of the moving block facing the expansion block is provided with a second inclined surface. The first inclined surface and the second inclined surface slide against each other. The end of the expansion block located on the outer side of the annular shell is fixed to a pressure plate, and the pressure plate abuts against the inner wall of the sink.

[0008] Furthermore, the outer peripheral sidewall of the annular shell is machined with external threads, and one end of the protective cylinder is configured as an open structure with an internal thread adapted to the external thread on the inner wall of the opening. The protective cylinder can be detachably assembled to the outside of the annular shell by means of internal and external thread engagement.

[0009] Furthermore, a buffer cylinder is movably sleeved on the outside of the protective cylinder, and a buffer spring is provided between the buffer cylinder and the protective cylinder. The two ends of the buffer spring are respectively fixed to the outer wall of the protective cylinder and the inner wall of the buffer cylinder.

[0010] Furthermore, the protective cylinder has a first measuring port on its circumferential sidewall, and the buffer cylinder has a second measuring port that is directly opposite and connected to the first measuring port on its circumferential sidewall. The observation end of the L-shaped observation nail faces the positions of the first and second measuring ports.

[0011] Furthermore, the settling tank is a circular settling tank, which facilitates on-site trenching construction.

[0012] Furthermore, the clamping plate has an arc-shaped structure, and an anti-slip pad is fixedly provided on the side facing the wall of the settling tank.

[0013] Furthermore, the central circular opening of the annular shell is open and permeable to the interior of the annular shell.

[0014] Furthermore, the inner diameter of the central opening of the annular shell is larger than the exposed height of the L-shaped observation nail, which facilitates smooth insertion and assembly.

[0015] The beneficial effects of this utility model by adopting the above structure are as follows:

[0016] 1. This device abandons the traditional one-time fixing method of expansion bolts and adopts a ring shell with a circumferential locking unit and inclined tension structure. It can be locked and fixed by turning in the forward direction and loosened and disassembled by turning in the reverse direction. The entire set of protective components can be reused without damage. When the protective cover is aged and damaged, it can be disassembled and replaced separately without the need to re-drill holes in the wall or replace fasteners, which greatly simplifies the maintenance process and saves consumables and labor costs.

[0017] 2. This device, through a double-layer buffer protection structure consisting of a protective cylinder, a buffer cylinder, and a buffer spring on the outside of the L-shaped observation nail, can effectively resist external force collisions at the construction site, prevent the L-shaped observation nail from shifting or bending due to external forces, ensure the accuracy and reliability of building settlement monitoring data, and extend the service life of the observation points.

[0018] 3. The protective cylinder and buffer cylinder of this device have corresponding first and second measuring ports that can be aligned. When conducting settlement elevation measurements, there is no need to disassemble any protective components. Simply rotate the protective cylinder so that the measuring port faces upward, and the measuring scale can be inserted to complete the observation reading. The operation is simple and quick.

[0019] 4. The protective cylinder and the annular shell of this device are connected by threads for detachable assembly, enabling separate assembly; vulnerable parts such as the protective cylinder and buffer cylinder can be disassembled and replaced separately without the need to remove the entire fixed base, reducing maintenance workload and time consumption, and significantly improving the flexibility of use.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0032] like Figures 1-8 As shown, this utility model discloses a building settlement monitoring device, including a wall 1, an L-shaped observation nail 2 fixedly installed on the side wall of the wall 1, a settling groove 3 opened on the side wall of the wall 1, and the L-shaped observation nail 2 located at the center of the settling groove 3; a protective component is installed inside the settling groove 3, the protective component includes an annular shell 4 and a protective cylinder 5, a locking unit 6 is installed on the annular shell 4 and is fastened to the inside of the settling groove 3 by means of the locking unit 6, the protective cylinder 5 is threadedly connected to the annular shell 4, and the L-shaped observation nail 2 penetrates the annular shell 4 and extends into the inside of the protective cylinder 5.

[0033] By opening a groove 3 in the wall 1 and placing the L-shaped observation nail 2 in the center of the groove 3, the groove 3 provides space for the embedded installation and positioning of the protective components. The annular shell 4 can be securely locked in the groove 3 by means of the locking unit 6. It is easy to disassemble and reassemble and can be reused. The protective cylinder 5 is threadedly connected to the annular shell 4 and covers the outside of the L-shaped observation nail 2. It can not only play a role in protecting the observation nail from impact and ensuring the accuracy of settlement monitoring, but also can be quickly disassembled and assembled through the thread, which is convenient for later inspection and maintenance.

[0034] like Figures 1-8As shown, the locking units 6 are evenly arranged around the annular shell 4. The locking unit 6 includes a threaded rod 7 and an expansion block 10. One end of the threaded rod 7 is rotatably connected to the inner wall of one side of the annular shell 4 via a bearing, and the other end is rotatably passed through the outer wall of the other side of the annular shell 4 via a bearing and fixed to a knob 8. Each threaded rod 7 is arranged parallel to the central axis of the annular shell 4. The threaded rod 7 is externally threaded to a moving block 9. The expansion block 10 slides through the circumferential side wall of the annular shell 4 and is arranged in a one-to-one correspondence with the moving block 9. The end of the expansion block 10 located inside the annular shell 4 is provided with a first inclined surface 11, and the side of the moving block 9 facing the expansion block 10 is provided with a second inclined surface 12. The first inclined surface 11 and the second inclined surface 12 slide against each other. The end of the expansion block 10 located outside the annular shell 4 is fixed to a pressure plate 13, which abuts against the inner wall of the sink 3.

[0035] The locking unit 6 is evenly distributed around the circumference of the annular housing 4 and consists of a threaded rod 7, an expansion block 10, a moving block 9, and a pressing plate 13. The threaded rod 7 is mounted on the annular housing 4 via a bearing and has a knob 8 at its outer end, which is parallel to the housing axis. Rotating the knob 8 can drive the threaded rod 7 to rotate and drive the moving block 9 to move axially. Then, through the inclined surface transmission between the moving block 9 and the expansion block 10, the expansion block 10 is pushed to slide outward along the radial direction of the housing, so that the outer pressing plate 13 is pressed tightly against the inner wall of the sink 3, thereby achieving the tension and fixation of the annular housing 4 in the sink 3. It can be loosened and disassembled by twisting in the opposite direction. The structure is simple, the locking is firm, and it can be repeatedly disassembled and reassembled without damage.

[0036] like Figures 1-8 As shown, the outer peripheral sidewall of the annular shell 4 is machined with external threads, and one end of the protective cylinder 5 is set as an open structure. The inner wall of the opening is provided with an internal thread that matches the external thread. The protective cylinder 5 can be detachably assembled to the outside of the annular shell 4 by the engagement of the internal and external threads. The connection structure is simple, the disassembly and assembly are convenient, and it is easy to disassemble and replace the protective cylinder 5 separately and carry out subsequent maintenance.

[0037] like Figures 1-8 As shown, a buffer cylinder 14 is movably sleeved on the outside of the protective cylinder 5. A buffer spring 15 is installed between the buffer cylinder 14 and the protective cylinder 5. The two ends of the buffer spring 15 are fixed to the outer wall of the protective cylinder 5 and the inner wall of the buffer cylinder 14, respectively. Through the elastic buffer structure, it can resist external impact and collision, effectively buffer and unload the force, avoid the impact force from acting directly on the protective cylinder 5, and improve the protection effect.

[0038] like Figures 1-8 As shown, the protective cylinder 5 has a first measuring port 16 on its circumferential side wall, and the buffer cylinder 14 has a second measuring port 17 on its circumferential side wall that is directly opposite and connected to the first measuring port 16. The observation end of the L-shaped observation nail 2 faces the first measuring port 16 and the second measuring port 17.

[0039] When carrying out settlement measurement work, rotate the protective cylinder 5 to make the measuring port face upward. Insert the measuring rod through the aligned measuring port and position it against the end of the L-shaped observation nail. Then, use a level to observe the reading of the rod and compare it with the elevation. Settlement monitoring and measurement can be completed without disassembling the protective structure. The operation is simple and efficient.

[0040] like Figures 1-8 As shown, the settling tank 3 is circular, which facilitates on-site grooving construction; the clamping plate 13 has an arc-shaped structure, and an anti-slip pad is fixed on the side facing the wall of the settling tank 3; the central circular opening of the annular shell 4 is open and connected to the interior of the annular shell 4, allowing for direct observation of the arrangement and assembly of the internal components of the annular shell 4, which facilitates the alignment, installation, debugging and maintenance of the internal structure such as the locking unit 6; the inner diameter of the central circular opening of the annular shell 4 is larger than the exposed height of the L-shaped observation nail 2, which facilitates the smooth insertion and assembly of the L-shaped observation nail 2.

[0041] In practical use, pre-installation and positioning: a groove 3 is opened on the side wall of the building wall 1, and a round hole is opened at the center of the groove 3. Then, the L-shaped observation nail 2 is fixed in the round hole, and then the annular shell 4 is put on the outside of the L-shaped observation nail 2 and placed in the center of the groove 3.

[0042] Locking and fixing: Rotate each knob 8 to drive the threaded rod 7 to rotate, and drive the moving block 9 to slide axially; through the inclined plane transmission of the first inclined plane 11 and the second inclined plane 12, push the expansion block 10 to extend outward radially, drive the arc-shaped pressing plate 13 to press the inner wall of the sink 3, and use the tension friction to achieve a boltless and holeless stable fixation of the annular shell 4.

[0043] Protective assembly: The protective cylinder 5 is screwed onto the outside of the annular shell 4 to cover the entire L-shaped observation nail 2. The outer buffer cylinder 14, together with the buffer spring 15, forms an elastic anti-collision protective layer to resist external impacts and collisions.

[0044] Settlement measurement: There is no need to disassemble the protective cylinder 5 and the buffer cylinder 14. Simply rotate the protective cylinder 5 so that the first measuring port 16 and the second measuring port 17 face upwards. Insert the measuring rod from the measuring port and connect it directly with the end of the L-shaped observation nail. With the help of a level, the elevation measurement and settlement data acquisition can be completed.

[0045] Disassembly and maintenance: When the protective cover needs to be replaced or repaired, first rotate the protective cylinder 5 off the annular shell 4 in the opposite direction, then turn the knob 8 in the opposite direction to disengage the inclined surface from the transmission. The expansion block 10 and the clamping plate 13 will retract, and the annular shell 4 and the protective components can be taken out directly. The entire process is non-destructive disassembly, and all components can be recycled and reused. If the protective cylinder 5 is aged or damaged, it can be disassembled and replaced by turning it off separately without removing the annular shell 4.
