Description

Technical Field

[0001] The utility model relates to the technical field of building engineering quality inspection, in particular to a settlement observation mark structure. Background Technique

[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 buildings, which will inevitably cause the deformation of the foundation and the 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 exploration, design and construction, the necessity and importance of settlement observation of buildings (structures) are becoming more and more obvious. The current specifications also stipulate that settlement observation should be carried out for high-rise buildings, high-rise structures, important ancient buildings, continuous production facility foundations, power equipment foundations, landslide monitoring, etc. Especially during the construction of high-rise buildings, settlement observation is used to strengthen process monitoring, guide reasonable construction procedures, prevent uneven settlement during construction, timely feedback information, provide detailed first-hand data for the exploration, design and construction departments, and avoid damage to the main structure of the building or cracks that affect the structural use function caused by settlement, resulting in huge economic losses.

[0003] In the Chinese utility model patent with the publication number of CN214010282U, a telescopic settlement observation device is disclosed, which includes a telescopic rod mechanism and a protection box. The protection box includes a box body and a box door. The telescopic rod mechanism is arranged in the protection box. After the box door of the protection box is closed, it is flush with the outer surface of the building decoration layer. The telescopic rod mechanism includes a sleeve and a telescopic observation rod slidably arranged in the sleeve. When retracted, the observation end of the telescopic observation rod is located inside the box body, and when extended, the observation end is located outside the box body.

[0004] In view of the above related technologies, the inventor believes that there are the following defects: when the above device performs measurement operations, the observation rod is pulled out and only relies on the sleeve to provide support force. After long-term repeated use, the sleeve will gradually lose its original stability due to wear, resulting in a change in the height of the observation point on the observation rod, thus leading to inaccurate measurement results. Content of the Utility Model

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

[0006] The above technical object of the utility model is achieved by the following technical solutions: A settlement observation mark structure, including a housing disposed in the wall and having an opening on one side. An installation block is arranged in the housing. A square hole is horizontally opened on the installation block. An observation rod is slidably arranged in the square hole. A cover plate is hingedly arranged at the lower part of the observation rod near the opening of the housing. A fixing block is arranged at the bottom of the housing. A horizontal groove with a notch direction consistent with the opening direction of the housing is opened on the fixing block. After the observation rod slides out, the cover plate is inserted into the horizontal groove in a horizontal state. A locking component for fixing the cover plate is arranged in the fixing block, and a fixing component for fixing the observation rod is arranged in the installation block.

[0007] By adopting the above technical solutions, the housing, installation block, observation rod, cover plate, fixing block, locking component, and fixing component are provided. When observation is needed, the cover plate is pulled outwards to drive the observation rod to slide outwards along the square hole. Then the cover plate is rotated downwards until the plate surface of the cover plate is parallel to the observation rod. Then the observation rod is pushed inwards, and the observation rod is fixed by the fixing component. At the same time, the lower part of the cover plate also snaps into the horizontal groove, and the cover plate is fixed by the locking component. Then the measurement operation is carried out. At this time, not only the installation block provides support force for the observation rod, but the cover plate also provides support force for the observation rod, ensuring the stability of the position of the observation rod and avoiding the inaccuracy of the measurement result caused by the wear of a single support point after long-term use, which affects the position of the observation rod.

[0008] Further, a sliding hole is opened downwards on the lower side hole wall of the square hole. The fixing component includes a sliding rod slidably arranged in the sliding hole. The top of the sliding rod is an arc surface. A groove is arranged on the observation rod. When the observation rod slides out, the groove cooperates with the sliding rod to fix the observation rod.

[0009] By adopting the above technical solutions, the sliding hole, sliding rod, and groove are provided. When the observation rod slides out, the groove cooperates with the sliding rod to fix the observation rod.

[0010] Further, a first annular groove is arranged on the installation block around the outer periphery of the sliding hole. A first annular retaining piece and a first compression spring are also arranged on the sliding rod. The first annular retaining piece and the first compression spring are both placed in the first annular groove. One end of the first compression spring abuts against the end of the first annular groove far from the observation rod, and the other end abuts against the first annular retaining piece.

[0011] By adopting the above technical solutions, the first annular groove, first annular retaining piece, and first compression spring are provided. When the observation rod is in the unused state, the top of the sliding rod is flush with the hole wall of the square hole and abuts against the observation rod. At this time, the first compression spring is in a compressed state. When the observation rod moves, when the groove is directly above the sliding rod, the first compression spring pushes the first annular retaining piece and the sliding rod to rise, and the sliding rod cooperates with the groove to fix the observation rod.

[0012] Further, a round hole is downwardly formed in the groove wall on the lower side of the transverse groove. The locking assembly includes a limiting rod slidably disposed in the round hole. The top of the limiting rod is an arc surface. A round groove is formed on the outer side plate surface of the cover plate. When the cover plate is inserted into the transverse groove, the round groove cooperates with the limiting rod to fix the cover plate.

[0013] By adopting the above technical solution, the round hole, the limiting rod and the round groove are provided. When the cover plate is inserted into the transverse groove, the round groove cooperates with the limiting rod to fix the cover plate.

[0014] Further, a second annular groove is formed on the outer periphery of the fixing block around the round hole. A second annular retaining piece and a second compression spring are further disposed on the limiting rod. The second annular retaining piece and the second compression spring are both located in the second annular groove. Two ends of the second compression spring abut against one end of the second annular groove away from the transverse groove, and the other end abuts against the second annular retaining piece.

[0015] By adopting the above technical solution, the second annular groove, the second annular retaining piece and the second compression spring are provided. During the process of the cover plate being inserted into the transverse groove, the cover plate first presses the limiting rod into the round hole, so that the second annular retaining piece descends to compress the second compression spring. The cover plate continues to be inserted into the transverse groove. When the round groove is directly above the limiting rod, the second compression spring pushes the second annular retaining piece and the limiting rod to rise, and the limiting rod cooperates with the round groove to fix the cover plate, thereby providing a supporting force for the observation rod.

[0016] Further, the observation rod includes a square rod horizontally arranged. The square rod is slidably disposed in the square hole. A measuring rod is vertically arranged on the top surface of the square rod. An articulated shaft is further disposed at one end of the square rod close to the cover plate. The axis core of the articulated shaft is located in the horizontal plane and the axis core direction is perpendicular to the length direction of the square rod. A connecting plate perpendicular to the plate surface is disposed on the inner side plate surface of the cover plate. The connecting plate is hinged to the square rod through the articulated shaft. The distance from the articulated shaft to the cover plate is the same as the distance from the articulated shaft to the plane where the upper groove wall of the transverse groove is located. The width of the bottom of the transverse groove is the same as the thickness of the cover plate.

[0017] By adopting the above technical solution, the square rod, the measuring rod, the articulated shaft and the connecting plate are provided. The cover plate can be stably rotated through the articulated shaft. The distance from the articulated shaft to the cover plate is the same as the distance from the articulated shaft to the plane where the upper groove wall of the transverse groove is located, and the width of the bottom of the transverse groove is the same as the thickness of the cover plate, so that the cover plate can be stably clamped into the transverse groove.

[0018] Further, a limiting strip is disposed at the bottom of the square rod. When the cover plate rotates downward to be parallel to the square rod, the connecting plate abuts against the limiting strip.

[0019] By adopting the above technical solution, the limiting strip is provided to limit the rotation range of the connecting plate, ensuring that when the connecting plate rotates downward to its maximum angle, it can be accurately in the vertical state, thereby ensuring that the cover plate can be stably maintained in the horizontal state, facilitating the adjustment operation of the cover plate.

[0020] In summary, the utility model has the following beneficial effects: In this application, a housing, a mounting block, an observation rod, a cover plate, a fixing block, a locking assembly, and a fixing assembly are provided. When observation is required, the cover plate is pulled outwards to drive the observation rod to slide outwards along the square hole, and then the cover plate is rotated downwards until the plate surface of the cover plate is parallel to the observation rod. Then, the observation rod is pushed inwards, and the observation rod is fixed by the fixing assembly. At the same time, the lower part of the cover plate also snaps into the transverse groove, and the cover plate is fixed by the locking assembly. Then, the measurement operation is carried out. At this time, not only does the mounting block provide a supporting force for the observation rod, but the cover plate also provides a supporting force for the observation rod, ensuring the stability of the position of the observation rod and avoiding the inaccuracy of the position of the observation rod caused by the wear of a single support point after long-term use, thus affecting the measurement result.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0029] As Figures 1-6 shown, an embodiment of the present application discloses a settlement observation mark structure, which includes a housing 10, an observation rod 11, a cover plate 12, a fixing component 22, and a locking component 32. The housing 10 is disposed in the wall and has an opening on one side. An installation block 20 is provided in the housing 10. A square hole 21 is horizontally formed in the installation block 20. The observation rod 11 is slidably disposed in the square hole 21. The fixing component 22 is disposed in the installation block 20 for fixing the observation rod 11. The cover plate 12 is hingedly disposed at the lower part of the observation rod 11 near the opening of the housing 10. A fixing block 30 is provided at the bottom of the housing 10. The locking component 32 is disposed in the fixing block 30 for fixing the cover plate 12, providing a supporting force for the support rod, and ensuring the stability of the position of the observation rod 11.

[0030] Specifically, the observation rod 11 includes a square rod 112 disposed horizontally. The square rod 112 is slidably disposed in the square hole 21, so that the square rod 112 can slide along the square hole 21. A measuring rod 113 is vertically disposed on the top surface of the square rod 112 near the opening of the housing 10. The measuring rod 113 is used for placing a leveling staff. A hinge shaft 14 is further provided at one end of the square rod 112 near the cover plate 12. The axis of the hinge shaft 14 is in the horizontal plane and the axis direction is perpendicular to the length direction of the square rod 112. A connecting plate 13 perpendicular to the plate surface is provided on the inner plate surface of the cover plate 12. The connecting plate 13 is hinged to the square rod 112 through the hinge shaft 14, so that the cover plate 12 can rotate stably.

[0031] When setting up, a sliding hole 23 is opened downward on the lower hole wall of the square hole 21. The fixing component 22 includes a sliding rod 24 slidably arranged in the sliding hole 23, and the sliding rod 24 can slide up and down along the sliding hole 23. The top of the sliding rod 24 is an arc surface, and a groove 111 is provided on the square rod 112. When the observation rod 11 slides out, the groove 111 cooperates with the sliding rod 24 to fix the observation rod 11. The top of the sliding rod 24 is set as an arc surface to facilitate cooperation or separation with the groove 111. An installation block 20 is provided with a first annular groove 25 on the outer periphery of the sliding hole 23. The sliding rod 24 is also provided with a first annular retaining piece 26 and a first compression spring 27. Both the first annular retaining piece 26 and the first compression spring 27 are placed in the first annular groove 25. One end of the first compression spring 27 abuts against the end of the first annular groove 25 away from the observation rod 11, and the other end abuts against the first annular retaining piece 26. When the observation rod 11 is not in use, the top of the sliding rod 24 is flush with the hole wall of the square hole 21 and abuts against the square rod 112. At this time, the first compression spring 27 is in a compressed state. When the observation rod 11 moves, when the groove 111 is directly above the sliding rod 24, the first compression spring 27 pushes the first annular retaining piece 26 and the sliding rod 24 to rise, and the sliding rod 24 cooperates with the groove 111 to fix the observation rod 11.

[0032] A transverse groove 31 with a notch direction consistent with the opening direction of the housing 10 is opened on the fixing block 30. The distance from the hinge shaft 14 to the cover plate 12 is the same as the distance from the hinge shaft 14 to the plane where the upper groove wall of the transverse groove 31 is located. The width of the bottom of the transverse groove 31 is the same as the thickness of the cover plate 12, so that the cover plate 12 can be stably clamped into the transverse groove 31. A limiting strip 15 is provided at the bottom of the square rod 112. When the cover plate 12 rotates downward to the horizontal state, the connecting plate 13 abuts against the limiting strip 15. The limiting strip 15 is used to limit the rotation range of the connecting plate 13 to ensure that when the connecting plate 13 rotates downward to its maximum angle, it can be accurately in the vertical state, so as to ensure that the cover plate 12 can be stably maintained in the horizontal state, which is convenient for adjusting the cover plate 12 and then clamping it into the transverse groove 31.

[0033] During specific setting, a round hole 33 is downwardly formed in the groove wall below the transverse groove 31. The locking assembly 32 includes a limiting rod 34 slidably disposed in the round hole 33. The limiting rod 34 can slide up and down along the round hole 33. The top of the limiting rod 34 is an arc surface. A round groove 121 is provided on the outer side plate surface of the cover plate 12. When the cover plate 12 is inserted into the transverse groove 31, the round groove 121 cooperates with the limiting rod 34 to fix the cover plate 12. The top of the limiting rod 34 is set as an arc surface to facilitate the cooperation or separation with the round groove 121. A second annular groove 35 is provided on the outer periphery of the fixing block 30 at the round hole 33. A second annular retaining piece 36 and a second compression spring 37 are further provided on the limiting rod 34. Both the second annular retaining piece 36 and the second compression spring 37 are located in the second annular groove 35. Two ends of the second compression spring 37 abut against one end of the second annular groove 35 away from the transverse groove 31, and the other end abuts against the second annular retaining piece 36. During observation, the cover plate 12 is pulled outwards to drive the observation rod 11 to slide outwards along the square hole 21. Subsequently, the cover plate 12 is rotated downwards until the plate surface of the cover plate 12 is parallel to the observation rod 11. Then the observation rod 11 is pushed inwards. During the process of the cover plate 12 being inserted into the transverse groove 31, the cover plate 12 first presses the limiting rod 34 into the round hole 33, so that the second annular retaining piece 36 descends to compress the second compression spring 37. The cover plate 12 continues to be inserted into the transverse groove 31. When the round groove 121 is directly above the limiting rod 34, the second compression spring 37 pushes the second annular retaining piece 36 and the limiting rod 34 to rise, and the limiting rod 34 cooperates with the round groove 121 to fix the cover plate 12, thereby providing a supporting force for the observation rod 11. The locking assembly 32 and the round groove 121 are arranged in three groups at intervals, so that the fixing effect on the cover plate 12 is better.

[0034] A square pipe 16 is outwardly provided on the side wall of the housing 10 relative to the opening. One end of the square rod 112 away from the cover plate 12 is located in the square pipe 16, so that the length of the square rod 112 can be longer and the stability is better. A limiting groove 17 is formed in the inner wall of the square pipe 16 along its length direction. A limiting block 18 slidably matched with the limiting groove 17 is provided at one end of the square rod 112 away from the cover plate 12 to limit the maximum distance of the observation rod 11 sliding outwards and prevent the observation rod 11 from sliding out of the square hole 21 when sliding outwards.

[0035] A cam lock is provided on the upper part of the cover plate 12. When the observation point is not in use, the cover plate 12 is locked to protect the observation point from being damaged by people. And the key inserted into the cam lock can be used as a handle to facilitate pulling out the cover plate 12 and the observation rod 11.

[0036] In this embodiment, the working principle of a settlement observation marking structure is as follows: When observation is required, the cover plate 12 is pulled outwards to drive the observation rod 11 to slide outwards along the square hole 21. When the groove 111 passes directly above the sliding rod 24, the first compression spring 27 pushes the first annular stop 26 and the sliding rod 24 upwards to fix the observation rod 11. Continuing to pull outwards until the limit block 18 contacts the end of the limit groove 17, the sliding rod 24 is pressed down during the movement of the observation rod 11. Subsequently, the cover plate 12 is rotated downwards until the connecting plate 13 contacts the limit strip 15. At this time, the surface of the cover plate 12 is parallel to the observation rod 11. Then, the observation rod 11 is pushed inwards, driving the cover plate 12 to also move into the transverse groove 31. During the movement of the cover plate 12 into the transverse groove 31, the limit rod 34 is pressed into the round hole 33, causing the second annular stop 36 to descend and compress the second compression spring 37. The observation rod 11 and the cover plate 12 continue to be pushed inwards. When the groove 111 is directly above the sliding rod 24, the first compression spring 27 pushes the first annular stop 26 and the sliding rod 24 upwards to fix the observation rod 11. At the same time, the round groove 121 is directly above the limit rod 34, and the second compression spring 37 pushes the second annular stop 36 and the limit rod 34 upwards to fix the cover plate 12. Subsequently, the leveling staff is placed on the measuring rod 113 for measurement operations. At this time, not only does the mounting block 20 provide a supporting force for the observation rod 11, but the cover plate 12 also provides a supporting force for the observation rod 11, ensuring the stability of the position of the observation rod 11 and avoiding inaccurate position of the observation rod 11 caused by a single support point after long-term use, thus affecting the measurement results.

[0037] The above are only the preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions within the idea of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and refinements should also be regarded as within the protection scope of the present invention.
