Technical Field

[0001] The utility model relates to the technical field of construction engineering quality detection, in particular to a novel settlement observation point structure. Background Art

[0002] With the development of industrial and civil construction, various complex and large-scale engineering buildings are increasing day by day. The construction of engineering buildings has changed the original state of the ground and exerted a certain pressure on the foundation of the building, which will inevitably cause deformation of the foundation and surrounding strata. In order to ensure the normal service life and safety of buildings (structures), and to provide reliable data and corresponding settlement parameters for future survey, design and construction, the necessity and importance of building (structure) settlement observation are becoming more and more obvious. The current specifications also stipulate that settlement observations should be carried out for high-rise buildings, tall structures, important ancient buildings, foundations of continuous production facilities, foundations of power equipment, and landslide monitoring. Especially in the construction process of high-rise buildings, settlement observations should be used to strengthen process monitoring, guide reasonable construction procedures, prevent uneven settlement during construction, and provide timely feedback information to provide detailed first-hand information for the survey, design and construction departments to avoid damage to the main structure of the building due to settlement or cracks that affect the use function of the structure, causing huge economic losses.

[0003] A concealed settlement observation point device is disclosed in a Chinese utility model patent with publication number CN217541901U, including a sleeve, a measuring bolt and an external measuring point. A first chamber and a second chamber are formed inside the sleeve, and the first chamber and the second chamber are separated by a shrinkage partition, wherein a thread is formed in the first chamber; the measuring bolt is divided into a variable section and an external measuring section, the variable section is threadedly connected to the first chamber, and the measuring bolt changes the extension or retraction amount of the external measuring section in the second chamber by screwing; the external measuring point is arranged on the external measuring section of the measuring bolt.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: during the use of the above-mentioned device, the staff needs to rotate the measuring bolt to turn its external measuring point out of the sleeve, and then use the instrument to measure and record it. The measuring bolt has a large rotation stroke, which increases the labor intensity of the workers and reduces the efficiency of settlement observation work. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a novel settlement observation point structure.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions:

[0007] A new type of settlement observation point structure, including a shell set in a wall and open on one side, a guide block is set in the shell, a accommodating hole is horizontally opened in the guide block, an observation rod is slidably set in the accommodating hole, a strip groove is opened at the bottom of the guide block, which is consistent with the length direction of the accommodating hole and connected to the accommodating hole, a fixed block fixedly connected to the observation rod is slidably set in the strip groove, a traction assembly connected to the fixed block is set below the guide block in the shell, a hinge shaft is fixedly set at the bottom of the shell opening, a cover plate is hingedly set on the hinge shaft, a traction rope is set between the cover plate and the traction assembly, and when the cover plate is opened, the traction assembly is pulled by the traction rope to drive the fixed block and the observation rod to slide outward.

[0008] By adopting the above technical scheme, a shell, a guide block, an observation rod, a fixed block, a traction assembly, a cover plate and a traction rope are provided. When settlement observation is required, the cover plate is opened first. During the opening process of the cover plate, the traction assembly is pulled by the traction rope to drive the fixed block to slide along the strip groove, thereby driving the observation rod to slide outward. After the observation rod slides out, the level ruler is placed on the end of the observation rod, and then observation is performed through the level. The operation is simple and convenient, and the labor intensity of workers is reduced. The cover plate is used to protect the observation rod to prevent the observation rod from being affected by external environmental factors, which may affect the accuracy of observation.

[0009] Furthermore, the traction assembly includes a traction rope and a fixed tube arranged on the inner wall of the shell, the fixed tube is arranged along the length direction of the observation rod, a sliding rod is slidably arranged in the fixed tube, one end of the sliding rod extends out of the fixed tube and is provided with a mounting frame, a pulley is rotatably arranged on the mounting frame, the wheel core of the pulley is located on a horizontal plane and is perpendicular to the rod core of the observation rod, one end of the traction rope is fixedly connected to the side wall of the shell below the traction assembly, and the other end is fixedly connected to the fixed block after passing around the pulley, and a traction column is provided at the lower part of the inner plate surface of the cover plate, one end of the traction rope is connected to the traction column, and the other end is fixedly connected to the mounting frame.

[0011] Furthermore, a slide groove which is consistent with the length direction of the fixed tube is opened on the inner wall of the fixed tube, a slider is slidably arranged in the slide groove, and the slider is fixedly connected to one end of the slide rod located in the fixed tube.

[0012] By adopting the above technical solution, a slide groove and a slider are set, and the axial direction of the slide rod is limited by the slide rail slide groove, so that the pulley is also limited, preventing the pulley from rotating along the slide rod core and causing the pulling rope to detach from the pulley.

[0013] Furthermore, a sleeve is provided on the side wall of the shell relative to the opening and is coaxially arranged with the accommodating hole, and a tension spring is provided in the sleeve. One end of the tension spring is fixedly connected to the bottom of the sleeve, and the other end is fixedly connected to the observation rod.

[0017] Furthermore, both ends of the upper surface of the limiting plate are provided with stoppers, and the tops of the stoppers are higher than the tops of the positioning blocks.

[0018] By adopting the above technical solution, stoppers are arranged at both ends of the limit plate to prevent the limit plate from slipping out of the square hole and falling off. The top of the stopper is arranged to be higher than the top of the positioning block, which is convenient for the staff to operate.

[0019] Furthermore, a cam lock is provided on the upper portion of the cover plate.

[0020] By adopting the above technical solution, a cam lock is provided on the upper part of the cover plate, and the cover plate is locked when the observation point is not in use, thereby protecting the observation point and preventing human damage.

[0021] To sum up, the utility model has the following beneficial effects: in this application, a shell, a guide block, an observation rod, a fixed block, a traction assembly, a cover plate and a traction rope are provided. When settlement observation is required, the cover plate is opened first. During the opening process of the cover plate, the traction assembly is pulled by the traction rope to drive the fixed block to slide along the strip groove, thereby driving the observation rod to slide outward.

The operation is simple and convenient, which reduces the labor intensity of workers. The cover plate is used to protect the observation rod to prevent the observation rod from being affected by external environmental factors, which may affect the accuracy of observation.

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0028] like Figure 1-4 As shown, the embodiment of the present application discloses a novel structure of a settlement observation point, including a shell 10 which is arranged in a wall and has an opening on one side, an observation rod 13, a cover plate 30 and a traction assembly 20. A guide block 11 is arranged in the shell 10, and a receiving hole 12 is horizontally opened in the guide block 11. The observation rod 13 is slidably arranged in the receiving hole 12, so that the observation rod 13 only slides out of the shell 10 when measurement is required, and is located in the shell 10 when measurement is not required, so as to avoid damage to the observation rod 13. A hinge shaft 16 is fixedly arranged at the bottom of the opening of the shell 10, and the cover plate 30 is hingedly arranged on the hinge shaft 16. The rotation angle of the cover plate 30 is 90 degrees. The cover plate 30 is used to protect the components in the shell 10. The traction assembly 20 is arranged on the side wall of the shell 10 below the guide block 11. A traction rope 31 is arranged between the cover plate 30 and the traction assembly 20. When the cover plate 30 is opened, the traction assembly 20 is pulled by the traction rope 31 to drive the observation rod 13 to slide outward. The operation is simple and convenient, and the labor intensity of the workers is reduced.

[0029] Specifically, the housing 10 is provided with a sleeve 40 extending outwardly from the side wall relative to the opening and arranged coaxially with the receiving hole 12. The inner diameter of the sleeve 40 is consistent with the diameter of the receiving hole 12, so that the length of the observation rod 13 can be longer and the stability is better. A strip groove 14 is provided at the bottom of the guide block 11, which is consistent with the length direction of the receiving hole 12 and is connected to the receiving hole 12. A fixed block 15 fixedly connected to the observation rod 13 is slidably provided in the strip groove 14. When the cover 30 is opened, the traction assembly 20 is pulled by the traction rope 31 to drive the fixed block 15 to slide along the strip groove 14, thereby driving the observation rod 13 to slide outward.

[0030] The traction assembly 20 includes a fixed tube 22 and a slide bar 23. The fixed tube 22 is arranged on the inner wall of the housing 10 and arranged along the length direction of the observation rod 13. The slide bar 23 is slidably arranged in the fixed tube 22, so that the slide bar 23 can slide in the fixed tube 22 along the length direction of the fixed tube 22. The fixed tube 22 is extended from one end of the slide bar 23 and a mounting frame 24 is arranged. A pulley 25 is rotatably arranged on the mounting frame 24. The wheel core of the pulley 25 is located on a horizontal plane and is perpendicular to the rod core of the observation rod 13. One end of the pulling rope 21 is fixedly connected to the side wall of the housing 10 located below the traction assembly 20, and the other end is fixedly connected to the fixed block 15 after passing through the pulley 25. When the pulley 25 moves along the length direction of the fixed tube 22, since one end of the pulling rope 21 is fixed, the other end of the pulling rope 21 drives the fixed block 15 and the observation rod 13 to slide outward, and the sliding stroke of the fixed block 15 is twice the moving stroke of the pulley 25. A traction column 32 is provided at the lower part of the inner surface of the cover plate 30, and a traction rope 31 is provided between the traction column 32 and the mounting frame 24. When the cover plate 30 is opened, the traction column 32 is driven to move, thereby driving the traction rope 31 to pull the mounting frame 24 and the pulley 25 to move. A slide groove 26 is provided on the inner wall of the fixed tube 22 in the same length direction thereof, and a slider 27 is slidably provided in the slide groove 26. The slider 27 is fixedly connected to one end of the slide rod 23 located in the fixed tube 22, and the axial direction of the slide rod 23 is limited, so that the pulley 25 is also limited, to prevent the pulley 25 from rotating along the core of the slide rod 23 and causing the traction rope 21 to separate from the pulley 25.

[0031] A positioning block 50 is provided at the bottom of the housing 10, and a square hole is provided in the positioning block 50 along the length direction of the observation rod 13. A limit plate 51 is slidably provided in the square hole. After the cover plate 30 is opened, the limit plate 51 is slid outward along the square hole so that the limit plate 51 presses the cover plate 30 to limit the cover plate 30. Stoppers 52 are provided at both ends of the upper plate surface of the limit plate 51 to prevent the limit plate 51 from sliding out of the square hole and falling off. The top of the stopper 52 is set to be higher than the top of the positioning block 50, which is convenient for the staff to operate.

[0032] During the specific setting, a tension spring 41 is arranged in the sleeve 40, one end of the tension spring 41 is fixedly connected to the bottom of the sleeve 40, and the other end is fixedly connected to the observation rod 13. During the opening process of the cover 30, the observation rod 13 is driven to move outward by the driving assembly. At this time, the tension spring 41 is stretched, and the cover 30 is fixed by the limit plate 51. The level ruler can be placed on the end of the observation rod 13, and then observation is performed through the level; after the observation is completed, the limit plate 51 is opened, and the spring begins to contract, driving the observation rod 13 to move inward, thereby driving the cover 30 to close through the traction assembly 20.

[0033] A cam lock 33 is provided on the upper part of the cover plate 30 to lock the cover plate 30 when the observation point is not in use, thereby protecting the observation point and preventing human damage.

[0034] The use principle of a new type of settlement observation point structure in this embodiment is:

[0035] When it is necessary to observe the settlement, the cam lock 33 is first opened, and then the cover 30 is opened. During the opening process of the cover 30, the traction column 32 is driven to move, so that the traction rope 31 pulls the mounting frame 24 and the pulley 25 to move. Since one end of the traction rope 21 is fixed, the other end of the traction rope 21 drives the fixed block 15 and the observation rod 13 to slide outward during the movement of the pulley 25. During the outward sliding process of the observation rod 13, the tension spring 41 is stretched; when the cover 30 is fully opened, the observation rod 13 moves to the specified position, and the limit plate 51 is pushed out , the limit plate 51 presses the cover plate 30 to limit the cover plate 30, and then the level ruler is placed on the end of the observation rod 13, and observation is performed through the level; after the observation is completed, the limit plate 51 is reset. At this time, the tension spring 41 begins to contract, driving the observation rod 13 to move inward, thereby driving the fixed block 15, the pulling rope 21, and the pulley 25 to move. During the movement of the pulley 25, the cover plate 30 is closed through the pulling rope 31 and the pulling column 32, and then the cam lock 33 is locked. The operation is simple and convenient, which reduces the labor intensity of the workers.

[0036] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
