Description

Technical Field

[0001] The invention relates to the field of measurement of uneven settlement of buildings, in particular to a simulation measurement device for uneven settlement of buildings. Background Art

[0002] Before the construction of buildings and geotechnical structures, the self-weight stress caused by the gravity of the soil has already existed in the foundation. The load of buildings and geotechnical structures is transmitted to the foundation through the bottom surface of the foundation or embankment, which changes the original stress state of the natural soil layer. Under the action of the additional three-dimensional stress components, vertical, lateral and shear deformations are generated in the foundation, resulting in vertical and lateral displacements of each point. The vertical deformation of the foundation surface is called foundation settlement, or foundation settlement.

[0003] After massive searches, it was found that the prior art publication number is CN 112880638 B, which discloses a high-rise building settlement detection device and a settlement detection method, including a foundation and a wall. A U-shaped tube is provided in the foundation. The inner wall of the U-shaped tube is slidably connected with a first slide plate and a second slide plate. The first slide plate is placed on the left side of the U-shaped tube, and the second slide plate is placed on the right side of the U-shaped tube. The outer wall of the first slide plate is fixedly connected with a piston rod, and the outer wall of the second slide plate is fixedly connected with a measuring ruler, and the measuring ruler is provided with saw teeth. The outer wall of the foundation is fixedly connected with a fixing rod, and the end of the fixing rod away from the foundation is fixedly connected with a fixing seat, and a timing mechanism is provided on the fixing seat. The wall is fixedly connected with a pressure rod.

[0004] Therefore, based on the above retrieval and in combination with the existing building settlement measuring device, at present, when measuring the settlement of a building, it is impossible to determine whether the building has settled or deflected, because the deflection of the building will also cause the current measuring device to detect that the building has settled. If the deflection is too large, it will directly lead to the judgment of whether the building settlement meets the standard. Therefore, the present invention can directly measure the deflection and vertical settlement of the building respectively, and the measurement structure of the building settlement can offset the influence of the building deflection and ensure the measurement accuracy.

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the present invention provides a simulation measurement device for uneven settlement of buildings, which has the following beneficial effects:

[0018] 1. A simulation measuring device for uneven settlement of a building measures the inclination and deflection of a building wall through a building offset measuring component. When the building wall inclines and deflects backward, the length of the part of the stretched steel cable exposed to the outside is shortened compared to the initial state. Under the pull of the positioning spring, the moving block moves left along the cross plate, and the stretched steel cable always remains stretched. The offset pointer connected to the left end of the moving block moves left synchronously. The moving distance of the offset pointer is judged by the offset scale, and then the offset size of the building wall can be obtained. The higher the value read by the offset scale, the greater the deflection of the building wall, so as to judge the safety of the building.

[0019] 2. A simulation measuring device for uneven settlement of a building, which measures the vertical settlement of a building wall through a building settlement measuring component, is different from the measurement of the deflection of the building wall. When the building wall settles, the measuring frame fixed on it moves downward synchronously, the vertical frame fixed in the measuring frame moves downward synchronously, and the storage liquid frame fixed in the vertical frame moves downward synchronously, and the lower end of the piston plate in the storage liquid frame is connected with a telescopic rod, a retaining rod, a gyroscope and the telescopic rod in sequence, and the lower end of the telescopic rod is fixedly connected to a ground mounting plate. Therefore, when the building wall settles, the telescopic rod and the piston plate connected to its upper end move upward in the storage liquid frame relative to the downward moving building wall, thereby drawing the liquid filled in the display liquid frame into the storage liquid frame, and the liquid level in the display liquid frame moves downward. The building settlement is directly observed and judged by the downward moving liquid level and the settlement amount scale, thereby judging the building safety.

[0020] 3. A simulation measuring device for uneven settlement of a building. When the building wall deflects, for example, the building wall deflects backward, the telescopic rod and the telescopic rod will also deflect. At this time, the deflected telescopic rod and the telescopic rod will also cause the piston plate to move downward, thereby affecting the liquid level position in the display liquid frame. Therefore, the measures taken are that the building wall deflects backward, the straightened steel cable in the vertical frame moves upward, and the pull rope is driven upward synchronously to pull the telescopic plate in the piston plate to expose a larger space volume slot. At this time, the space below the piston plate is The time increases, and the liquid level in the synchronous display liquid frame decreases. Similarly, when the building wall deflects forward, the piston plate will move up, the straight steel cable in the vertical frame will move down, the pull rope will move down under the action of the spring, and the telescopic plate in the volume groove will move down. At this time, the space under the piston plate is reduced, and the liquid level in the synchronous display liquid frame rises, thereby offsetting the influence of the deflection of the building wall on the liquid level height in the display liquid frame, ensuring that the above structure can avoid the deflection of the building wall and the influence on the measurement of the vertical settlement of the building wall, thereby ensuring the accurate measurement of the settlement.

[0021] 4. This analog measuring device for uneven settlement of a building can directly read the settlement and deflection of the building wall through the settlement scale and the offset scale, and the read settlement and deflection values ​​are amplified to ensure reading accuracy.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, the present application proposes a simulation measurement device for uneven settlement of buildings.

[0033] In a typical implementation of the present application, Figure 1-8 As shown, a simulation measuring device for uneven settlement of a building includes a building wall 1 and a settlement measuring device 2 installed thereon, which is used to measure the uneven settlement of the building wall 1. The settlement measuring device 2 includes a measuring frame 6 fixed on the building wall 1, and a building offset measuring component 15 is fixedly arranged on the upper part of the measuring frame 6, which is used to measure the tilt offset of the building wall 1, which belongs to non-settlement measurement. A building settlement measuring component 16 is installed below the building offset measuring component 15, which is used to measure the vertical settlement of the building wall 1. A cover plate 5 is rotatably installed at the rear end of the measuring frame 6, and the cover plate 5 is provided with offset display holes 7 on the left and right sides above, which are used to directly display the tilt offset of the building wall 1. A settlement display hole 8 is provided in the middle of the cover plate 5, which is used to directly display the vertical settlement of the building wall 1. A telescopic rod 9 is slidably penetrated through the bottom side wall of the measuring frame 6. The lower end of the telescopic rod 9 is rotatably connected to a ground mounting plate 4, which is fixed to the ground. The settlement measuring device 2 of the entire building wall 1 is fixed to the ground through the mounting plate 4. The ground is used as a fixed reference point to measure the settlement of the building wall 1. The reference object always remains unchanged and the measurement is accurate.

[0034] Further, in the above scheme, the building offset measuring assembly 15 includes a transverse frame 11 fixed at the top of the measuring frame 6, a moving block 14 is slidably installed in the transverse frame 11, a positioning spring 20 is connected between the left end face of the moving block 14 and the left side wall of the transverse frame 11, a movable pulley groove 23 is penetrated on the right side of the bottom side wall of the transverse frame 11, a movable pulley group 22 is slidably installed in the movable pulley groove 23, a fixed pulley 19 is installed on the bottom side wall of the transverse frame 11, and the right end of the moving block 14 is fixedly connected to one end of the straightening cable 21, and the straightening cable 21 is connected to the right end of the moving block 14. After the other end passes through the movable pulley block 22 and the fixed pulley 19, it passes through the upper end of the telescopic rod 9 and passes through the side of the telescopic rod 9. The other end of the straightened steel cable 21 is fixedly connected to the upper end surface of the ground mounting plate 4. A horizontal plate 10 is horizontally passed through the moving block 14. The left and right ends of the horizontal plate 10 are respectively fixedly connected to the left and right side walls of the horizontal frame 11. The left and right side surfaces of the horizontal plate 10 are respectively provided with offset scales 12. The left and right end surfaces of the moving block 14 are fixedly connected with offset pointers 13. The offset scales 12 on the left and right sides are respectively provided with offset pointers 13 on the left and right side surfaces. 2 are respectively opposite to the offset display holes 7 on the left and right sides of the cover plate 5. When the building wall 1 tilts instead of sinking, for example, when the building wall 1 tilts backward, the length of the exposed portion of the stretched steel cable 21 is shortened compared to the initial state. Under the pull of the positioning spring 20, the moving block 14 moves leftward along the horizontal plate 10, and the stretched steel cable 21 always remains stretched straight. The offset pointer 13 connected to the left end of the moving block 14 moves leftward synchronously, and the moving distance of the offset pointer 13 is judged by the offset scale 12. The offset of the building wall 1 can be obtained, wherein the higher the value read on the offset scale 12, the greater the deflection of the building wall 1, and the safety of the building can be judged accordingly. Similarly, when the building wall 1 tilts backward, the length of the exposed portion of the stretched steel cable 21 increases compared to the initial state, thereby pulling the moving block 14 to move rightward along the horizontal plate 10, and then the offset of the building wall 1 can be obtained. In the above, the deflection of the building wall 1 can be directly read from the offset display hole 7;

[0035] It is worth mentioning that the deflection of the building wall 1 is generally very small. Therefore, when the building wall 1 deflects, the length of the straightened steel cable 21 exposed on the outside increases or decreases with the deflection. Because the straightened steel cable 21 is fixedly connected to the moving block 14 after passing around the movable pulley group 22, the distance that the straightened steel cable 21 pulls the moving block 14 to move is twice the length of the outside lengthening or shortening. The deflection amount is amplified by the movable pulley group 22, which facilitates the accurate reading of the deflection amount.

[0036] Further, in the above scheme, the building settlement measurement assembly 16 includes a vertical frame 18 fixed in the middle of the measuring frame 6, a partition 31 is arranged in the vertical frame 18, and the straightened steel cable 21 is vertically penetrated through the upper and lower side walls of the vertical frame 18. A storage liquid frame 29 is fixedly arranged behind the partition 31 in the vertical frame 18, and an opening is arranged on the rear end surface of the vertical frame 18. A display liquid frame 28 is fixedly arranged in the opening. The display liquid frame 28 is connected to the lower end of the storage liquid frame 29. A gyroscope 25 is rotatably installed on the upper end of the telescopic rod 9. A counterweight block 24 is fixedly connected to the lower end of the central axis of the gyroscope 25. A retaining rod 26 is fixedly connected to the upper end of the central axis of the gyroscope 25. The upper end of the retaining rod 26 is connected to the telescopic rod 27 through a ball pin head 32. The upper end of the telescopic rod 27 extends into the storage liquid frame 29 and is fixedly connected to a piston plate 30. The display liquid frame 28 is directly opposite to the settlement display hole 8 in the middle of the cover plate 5. The display liquid frame 28 is a rectangular frame. The rear side wall of the rectangular frame is a transparent plate, and the front side wall in the rectangular frame is provided with a settlement scale 17. When the building wall 1 settles, the measuring frame 6 fixed thereon moves downward synchronously, the vertical frame 18 fixed in the measuring frame 6 moves downward synchronously, and the storage liquid frame 29 fixedly arranged in the vertical frame 18 moves downward synchronously, and the lower end of the piston plate 30 in the storage liquid frame 29 is sequentially connected with the telescopic rod 27, the retaining rod 26, the gyroscope 25 and the telescopic rod 9, and the lower end of the telescopic rod 9 is fixedly connected to the ground mounting plate 4. Therefore, when the building wall 1 settles, the telescopic rod 9 and the piston plate 30 connected to its upper end move upward in the storage liquid frame 29 relative to the downwardly moving building wall 1, so that the liquid filled in the display liquid frame 28 is drawn into the storage liquid frame 29, and the liquid level in the display liquid frame 28 moves downward. The building settlement is directly observed and judged by the downwardly moving liquid level and the settlement scale 17, so as to judge the building safety;

[0037] In the initial state, the storage liquid frame 29 and the display liquid frame 28 are filled with a yellow solution with a flush liquid surface, and the sealing of the storage liquid frame 29 and the display liquid frame 28 needs to be ensured. If leakage occurs, measurement failure will occur.

[0038] It is worth mentioning that the bottom side wall of the piston plate 30 is provided with 36, and a telescopic plate 35 is provided inside 36. A plurality of springs are connected between the telescopic plate 35 and the top side wall inside 36. The upper end of the telescopic plate 35 is fixedly connected to one end of the pull rope 33, and the other end of the pull rope 33 is connected to the straightened steel cable 21. A spring 34 is provided in the middle of the pull rope 33. A gyroscope 25 is installed on the upper end of the telescopic rod 9, and the central axis of the gyroscope 25 is fixedly connected to the retaining rod 26. Therefore, no matter how the building wall 1 deflects and settles, the retaining rod 26 always remains vertical, and the upper end of the retaining rod 26 is connected to the telescopic rod 27 through the ball pin head 32. Under the above basic conditions, when the building wall 1 deflects, for example, the building wall 1 deflects backward, at this time, the telescopic rod 9 and the telescopic rod 27 will also deflect. At this time, the deflected telescopic rod 9 and the telescopic rod 27 will also cause the piston plate 30 to move downward, thereby affecting the display liquid frame 2 8, so the measures taken are that the building wall 1 deflects backward, the straightened steel cable 21 in the vertical frame 18 moves up, and the pull rope 33 is synchronously driven to move up, and the telescopic plate 35 in the piston plate 30 is pulled up to expose a larger volume groove 36. At this time, the space below the piston plate 30 increases, and the liquid level in the synchronous display liquid frame 28 decreases. Similarly, when the building wall 1 deflects forward, the piston plate 30 will move up, the straightened steel cable 21 in the vertical frame 18 will move down, and the pull rope 33 will move down under the action of the spring 33, and the telescopic plate 35 in the volume groove 36 will move down. At this time, the space below the piston plate 30 will decrease, and the liquid level in the synchronous display liquid frame 28 will rise, thereby offsetting the influence of the deflection of the building wall 1 on the liquid level height in the display liquid frame 28, ensuring that the above structure can be used to avoid the deflection of the building wall 1 and the influence on the measurement of the vertical settlement of the building wall 1, and ensure accurate measurement of the settlement.

[0039] Furthermore, the volume below the piston plate 30 in the above-mentioned storage liquid frame 29 is five times the volume of the display liquid frame 28. Since the settlement of the building wall 1 also changes very slightly, the settlement of the building wall 1 can be directly reflected in the liquid level height in the storage liquid frame 29. Since the volume below the piston plate 30 in the storage liquid frame 29 is five times the volume of the display liquid frame 28, the height of the liquid level in the display liquid frame 28 observed by us is magnified, which is convenient for accurately reading the settlement amount of the building wall 1.

[0040] Furthermore, the ground mounting plate 4 is integrally connected with the ground fixing plate 3 , and the ground fixing plate 3 is a T-shaped plate, which is used to ensure that the ground mounting plate 4 maintains a high stability and does not affect the settlement measurement of the building wall 1 .

[0041] Furthermore, transparent protective plates are provided at the offset display hole 7 and the settlement display hole 8 provided on the cover plate 5 to facilitate reading of the measurement values ​​and internal protection of the measurement frame 6 .

[0042] Working principle of the present invention: When in use, when the building wall 1 tilts rather than settles, for example, when the building wall 1 tilts backward, the length of the exposed portion of the stretched steel cable 21 is shortened compared to the initial state, and under the pull of the positioning spring 20, the moving block 14 moves left along the cross plate 10, and the stretched steel cable 21 always remains stretched, and the offset pointer 13 connected to the left end of the moving block 14 moves left synchronously, and the moving distance of the offset pointer 13 is judged by the offset scale 12, and then the offset size of the building wall 1 can be obtained, wherein, the higher the value read by the offset scale 12, the greater the deflection of the building wall 1, thereby judging the safety of the building, and similarly, when the building wall 1 tilts backward, the stretched steel cable 21 ... stretched steel cable 21 always remains stretched, and the stretched steel cable 21 always remains stretched, and the stretched steel cable 21 always remains stretched, and the stretched steel cable 21 always remains stretched, and the stretched steel cable 21 always remains stretched, and the stretched steel cable 21 always remains stretched, and the stretched steel cable 21 always remains stretched, and the stretched steel cable 21 always remains stretched, and the stretched steel cable 21 always remains stretched, and the stretched steel cable 21 always remains stretched, and the stretched steel cable 21 always remains stretched Compared with the initial state, the length of the portion of the cable 21 exposed to the outside increases, thereby pulling the moving block 14 to move rightward along the horizontal plate 10, and then the offset of the building wall 1 can be obtained. In the above, the deflection amount of the building wall 1 can be directly read from the offset display hole 7. The deflection amount of the building wall 1 is generally very small. Therefore, when the building wall 1 deflects, the length of the stretched steel cable 21 exposed outside increases or decreases with the deflection. Because the stretched steel cable 21 is fixedly connected to the moving block 14 after passing through the movable pulley group 22, the distance that the stretched steel cable 21 pulls the moving block 14 to move is twice the length of the outside lengthening or shortening. The deflection amount is amplified by the movable pulley group 22, which facilitates and accurately reads the deflection amount.

[0043] When the building wall 1 settles, the measuring frame 6 fixed thereon moves downward synchronously, the vertical frame 18 fixed in the measuring frame 6 moves downward synchronously, and the storage liquid frame 29 fixedly arranged in the vertical frame 18 moves downward synchronously, and the lower end of the piston plate 30 in the storage liquid frame 29 is sequentially connected with the telescopic rod 27, the retaining rod 26, the gyroscope 25 and the telescopic rod 9, and the lower end of the telescopic rod 9 is fixedly connected to the ground mounting plate 4. Therefore, the building wall 1 settles, and the telescopic rod 9 and the piston plate 30 connected to its upper end move upward in the storage liquid frame 29 relative to the downwardly moving building wall 1, so that the liquid filled in the display liquid frame 28 is drawn into the storage liquid frame 29, and the liquid level in the display liquid frame 28 moves downward, and the building settlement amount is directly observed and judged by the downwardly moving liquid level and the settlement amount scale 17, so as to judge the building safety;

[0044] In the initial state, the storage liquid frame 29 and the display liquid frame 28 are filled with a yellow solution with a flush liquid surface, and the sealing of the storage liquid frame 29 and the display liquid frame 28 needs to be ensured. If leakage occurs, measurement failure will occur.

[0045] It is worth mentioning that the bottom side wall of the piston plate 30 is provided with 36, and a telescopic plate 35 is provided inside 36. A plurality of springs are connected between the telescopic plate 35 and the top side wall inside 36. The upper end of the telescopic plate 35 is fixedly connected to one end of the pull rope 33, and the other end of the pull rope 33 is connected to the straightened steel cable 21. A spring 34 is provided in the middle of the pull rope 33. A gyroscope 25 is installed on the upper end of the telescopic rod 9, and the central axis of the gyroscope 25 is fixedly connected to the retaining rod 26. Therefore, no matter how the building wall 1 deflects and settles, the retaining rod 26 always remains vertical, and the upper end of the retaining rod 26 is connected to the telescopic rod 27 through the ball pin head 32. Under the above basic conditions, when the building wall 1 deflects, for example, the building wall 1 deflects backward, at this time, the telescopic rod 9 and the telescopic rod 27 will also deflect. At this time, the deflected telescopic rod 9 and the telescopic rod 27 will also cause the piston plate 30 to move downward, thereby affecting the display liquid frame 2 8, so the measures taken are that the building wall 1 deflects backward, the straightened steel cable 21 in the vertical frame 18 moves up, and the pull rope 33 is synchronously driven to move up, and the telescopic plate 35 in the piston plate 30 is pulled up to expose a larger volume groove 36. At this time, the space below the piston plate 30 increases, and the liquid level in the synchronous display liquid frame 28 decreases. Similarly, when the building wall 1 deflects forward, the piston plate 30 will move up, the straightened steel cable 21 in the vertical frame 18 will move down, and the pull rope 33 will move down under the action of the spring 33, and the telescopic plate 35 in the volume groove 36 will move down. At this time, the space below the piston plate 30 will decrease, and the liquid level in the synchronous display liquid frame 28 will rise, thereby offsetting the influence of the deflection of the building wall 1 on the liquid level height in the display liquid frame 28, ensuring that the above structure can be used to avoid the deflection of the building wall 1 and the influence on the measurement of the vertical settlement of the building wall 1, and ensure accurate measurement of the settlement.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
