Description

Technical Field

[0001] This application relates to the field of building formwork monitoring technology, and more specifically, to a formwork support frame foundation settlement monitoring device. Background Technology

[0002] With the development of construction technology, various formwork systems must be used in the construction of cast-in-place concrete structures. Common formwork support structures generally use steel or wooden beams assembled into formwork brackets, and steel or wooden poles are used to build scaffolding to support the brackets, which are then used in conjunction with steel formwork for concrete construction. In the construction of cast-in-place concrete structures, formwork collapse accidents often occur. In the analysis of formwork collapse and instability accidents, the proportion of accidents caused by foundation problems is relatively large. Due to inadequate foundation treatment of the formwork support frame or failure to strictly follow construction specifications, the foundation bearing capacity is insufficient, resulting in settlement during concrete pouring. Excessive deformation of the support frame due to sinking is the main cause of formwork safety accidents. The traditional method for detecting foundation settlement is to use optical instruments such as theodolites or levels for settlement observation. Such methods cannot achieve real-time monitoring, and the foundation settlement of the internal uprights of the formwork is difficult to observe due to the influence of line of sight.

[0003] Some existing technical solutions, by setting up a fiber Bragg grating demodulator and connecting it to a computer device via wired connection, can achieve high-precision real-time monitoring of the absolute settlement of the foundation of the pole at the observation point. The data is collected and analyzed by the fiber Bragg grating data acquisition software on the computer device. When the absolute value of the foundation settlement at the monitoring point exceeds the warning value, an early warning is issued in time, and the workers are evacuated to ensure their safety and provide a guarantee for the overall stability of the formwork support frame.

[0004] However, the above technical solutions still have some shortcomings. For example, the unit price of fiber Bragg grating static level is relatively high, resulting in a high cost of setting up the monitoring device. If several fiber Bragg grating static levels are used in series and connected to the fiber Bragg grating demodulator using optical fiber, a failure of one level may affect the monitoring accuracy of the other levels, which may lead to a failure of the monitoring device and make it impossible to guarantee the safety monitoring of the template support frame. Summary of the Invention

[0005] To address the aforementioned problems, this application provides a foundation settlement monitoring device for template support frames, employing the following technical solution:

[0006] A foundation settlement monitoring device for a template support frame includes a support rod for supporting the template and a support cylinder installed at the bottom of the support rod. A battery box is fixedly installed on the inner top wall of the support cylinder. The battery box has a cuboid structure, and its interior is divided into four identical battery compartments by a cross-shaped partition. Each battery compartment independently houses a battery. A suitable cover is installed at the bottom of the battery box. Monitoring boxes are fixedly installed on the four side walls of the battery box. Each monitoring box is equipped with an alarm triggering mechanism. The four sets of alarm triggering mechanisms are electrically connected to the four batteries respectively. Four alarm lights are fixedly installed on the top of the support cylinder in an array, and the alarm lights and alarm triggering mechanisms are distributed in a one-to-one correspondence.

[0007] By adopting the above technical solution, real-time monitoring boxes are installed in four directions at the bottom of the support rod of each support template. When abnormal settlement occurs in the foundation of the support rod, an alarm can be issued to promptly inform the staff of the location of the settlement. Moreover, the monitoring boxes in each direction work independently, which helps to ensure the fault tolerance and accuracy of the monitoring.

[0008] Furthermore, a slot is provided at the top of the support cylinder, and a limiting sleeve is fixedly installed at the top of the support cylinder. The support rod passes through the limiting sleeve and is inserted into the slot.

[0009] By adopting the above technical solution, the support rod is inserted into the slot and the limiting sleeve, and the bottom end is quickly fixed.

[0010] Furthermore, the alarm triggering mechanism includes a horizontal partition fixedly installed in the middle of the inner wall of the monitoring box. The horizontal partition divides the inner cavity of the monitoring box into an upper movable cavity and a lower movable cavity. A support plate is slidably installed in the lower movable cavity of the monitoring box. A monitoring column is fixedly installed at the bottom of the support plate and slides through the bottom of the monitoring box. A conductive pad is fixedly installed at the top of the support plate. A first electrode post and a second electrode post are fixedly installed at the top two ends of the conductive pad, respectively. Both the first electrode post and the second electrode post extend through the horizontal partition into the upper movable cavity. A conductive sheet is fixedly installed on the inner wall of the upper movable cavity of the monitoring box. The conductive sheet is distributed correspondingly to the first electrode post. A sliding rheostat is fixedly installed on the inner wall of the upper movable cavity of the monitoring box. The sliding rheostat is adapted to the top of the second electrode post.

[0011] By adopting the above technical solution, the bottom end of the monitoring column contacts the ground. When the foundation at the support rod settles, the bottom end of the monitoring column presses firmly against the ground, and the top end extends towards the upper movable cavity of the monitoring box, pushing the support plate upward. The support plate drives the first electrode column and the second electrode column to rise synchronously. When the first electrode column contacts the conductive plate, the circuit is connected, and the alarm light illuminates, indicating that the foundation at the location has settled. As the monitoring column continues to push the support plate upward, the end of the second electrode column moves on the sliding rheostat, changing the resistance of the circuit, which in turn changes the brightness of the alarm light, thereby informing the staff of the relative degree of foundation settlement.

[0012] Furthermore, a support base is fixedly installed at the bottom of the support cylinder, the circumferential cross-section of the support base is a right trapezoid, and the bottom end of the monitoring column is flush with the bottom of the support base.

[0013] By adopting the above technical solution, the support base increases the contact area with the ground and reduces the pressure on the contact surface with the ground, which helps to improve the stability of the support.

[0014] Furthermore, positioning posts are vertically fixed at both ends of the top of the tray, and both positioning posts extend through into the upper movable cavity. Two spaced positioning tubes are fixedly installed between the horizontal partition and the inner top wall of the monitoring box, and the two positioning posts are slidably sleeved with the two positioning tubes respectively.

[0015] By adopting the above technical solution, the top of the positioning column slides relatively inside the positioning tube during the pallet's ascent, ensuring the stability of the pallet's ascent.

[0016] Furthermore, a spring is fitted onto the column inside the lower movable cavity of the positioning column, and the two ends of the spring are fixedly connected to the inner bottom wall of the monitoring box and the bottom of the horizontal partition, respectively.

[0017] By adopting the above technical solution, the pallet will adaptively compress the spring during the rising process. When the staff maintains the support column at the foundation settlement point, the monitoring column is reset by using the restoring deformation force of the spring.

[0018] Furthermore, a support pad is fixedly installed on the inner circumference of the support cylinder, and the support pad slides vertically in contact with the monitoring column.

[0019] By adopting the above technical solution, the monitoring column slides relative to the support pad when it is raised and lowered, and the support pad provides support for the monitoring column, thus ensuring the stability of the monitoring column.

[0020] Furthermore, four horizontal frames arranged in a circular array are fixedly installed on the outer circumference of the support cylinder, and a level is fixedly installed on the inner bottom wall of the horizontal frames.

[0021] By adopting the above technical solution, the level ruler helps workers to intuitively observe the horizontal state of the support cylinder at the support rod, and also helps workers to observe the foundation settlement state of the template support frame from multiple angles.

[0022] Furthermore, a protractor is fixedly installed on the inner wall of the horizontal frame, a support shaft is fixedly installed at the center of the protractor, a collar is rotatably installed at the end of the support shaft, and a pointer and a conical needle are distributed collinearly on the outer circumference of the collar.

[0023] By adopting the above technical solution, the pointers remain vertically collinear under the action of the cone needle's gravity. When the foundation at the support rod settles, the support cylinder will tilt to the side with more severe settlement, which will cause the pointers to deflect relative to the scale of the protractor. The angle of deflection can, to a certain extent, intuitively reflect the foundation settlement situation, making it convenient for staff to observe.

[0024] In summary, this application includes the following beneficial technical effects:

[0025] 1. This application, through the setting of support cylinder, battery box, storage battery, monitoring box, alarm light and alarm triggering mechanism, can realize relatively independent real-time monitoring on the support rod of each support template, and can timely display the location of foundation settlement, ensuring the fault tolerance and accuracy of monitoring;

[0026] 2. This application, through the setting of a horizontal frame and a spirit level, facilitates workers to observe the horizontal status of the template support frame in a timely and intuitive manner, thereby reflecting the foundation settlement status;

[0027] 3. This application uses a horizontal frame, a protractor, a pointer, and a cone. Under the weight of the cone, the pointer keeps the points vertically collinear. When the foundation at the support rod settles, the support cylinder will tilt to the side with more severe settlement, causing the pointer to deflect relative to the scale of the protractor. The angle of deflection can intuitively reflect the foundation settlement to a certain extent, making it convenient for staff to observe and handle. Attached Figure Description

[0039] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0040] Example 1

[0041] Please see Figures 1-4 A foundation settlement monitoring device for a template support frame includes a support rod 1 for supporting the template and a support cylinder 2 installed at the bottom of the support rod 1. The top of the support cylinder 2 has a slot 10, and a limiting sleeve 11 is fixedly installed on the top of the support cylinder 2. The support rod 1 passes through the limiting sleeve 11 and is inserted into the slot 10 for quick fixation. A battery box 3 is fixedly installed on the inner top wall of the support cylinder 2. The battery box 3 has a cuboid structure, and its interior is divided into four identical battery compartments 5 by a cross partition 4. Each battery compartment 5 is independently equipped with a battery 6. A matching cover 7 is installed at the bottom of the battery box 3. Monitoring boxes 8 are fixedly installed on the four side walls of the battery box 3. Four alarm lights 9 are fixedly installed on the top of the support cylinder 2 in an array.

[0042] Each monitoring box 8 is equipped with an alarm triggering mechanism. Four sets of alarm triggering mechanisms are electrically connected to four batteries 6. Alarm lights 9 and alarm triggering mechanisms are distributed in a one-to-one correspondence. Each alarm triggering mechanism includes a horizontal partition 12 fixedly installed in the middle of the inner wall of the monitoring box 8. The horizontal partition 12 divides the inner cavity of the monitoring box 8 into an upper movable cavity and a lower movable cavity. A support plate 13 is slidably installed in the lower movable cavity of the monitoring box 8. A monitoring post 14 is fixedly installed at the bottom of the support plate 13, sliding through the bottom of the monitoring box 8. A conductive pad 15 is fixedly installed at the top of the support plate 13. A first electrode post 16 and a second electrode post 17 are fixedly installed at the top two ends of the conductive pad 15, respectively. Both the first electrode post 16 and the second electrode post 17 extend through the horizontal partition 12 into the upper movable cavity. A conductive sheet 18 is fixedly installed on the inner wall of the upper movable cavity of the monitoring box 8. The conductive sheet 18 and... The first electrode post 16 is distributed accordingly. A sliding rheostat 19 is fixedly installed on the inner wall of the movable cavity of the monitoring box 8. The sliding rheostat 19 is adapted to the top of the second electrode post 17. The bottom end of the monitoring post 14 is in contact with the ground. When the foundation at the support rod 1 settles, the bottom end of the monitoring post 14 presses against the ground, and the top end extends towards the upper movable cavity of the monitoring box 8, pushing the support plate 13 to rise. The support plate 13 drives the first electrode post 16 and the second electrode post 17 to rise synchronously. When the first electrode post 16 contacts the conductive sheet 18, the circuit is connected, and the alarm light 9 lights up, indicating that the foundation at the location has settled. When the monitoring post 14 pushes the support plate 13 to continue rising, the end of the second electrode post 17 moves on the sliding rheostat 19, changing the resistance of the circuit, thereby changing the brightness of the alarm light 9, thus informing the staff of the relative degree of foundation settlement.

[0043] A support base 20 is fixedly installed at the bottom of the support cylinder 2. The circumferential cross-section of the support base 20 is a right trapezoid. The support base 20 increases the contact area with the ground and reduces the pressure on the contact surface with the ground, which is beneficial to improving the stability of the support. The bottom end of the monitoring column 14 is flush with the bottom of the support base 20. Positioning columns 21 are vertically fixedly installed at both ends of the top of the support plate 13. Both positioning columns 21 extend through into the upper movable cavity. Two spaced positioning tubes 22 are fixedly installed between the horizontal partition 12 and the inner top wall of the monitoring box 8. The two positioning columns 21 are slidably sleeved with the two positioning tubes 22 respectively. During the process of the support plate 13 rising, the top ends of the positioning columns 21 slide relative to each other in the positioning tubes 22. To ensure the smoothness of the rise of the support plate 13, a spring 23 is sleeved on the column body of the positioning column 21 located in the lower movable cavity. The two ends of the spring 23 are fixedly connected to the inner bottom wall of the monitoring box 8 and the bottom of the horizontal partition 12, respectively. During the rise of the support plate 13, the spring 23 will be compressed adaptively. When the staff maintains the support column 1 at the foundation settlement point, the restoring deformation force of the spring 23 is used to reset the monitoring column 14. A support pad 24 is fixedly installed on the inner circumference of the support cylinder 2. The support pad 24 is in vertical sliding contact with the monitoring column 14. When the monitoring column 14 rises and falls, it slides relative to the support pad 24. The support pad 24 provides support for the monitoring column 14, ensuring the stability of the monitoring column 14.

[0044] The implementation principle of this embodiment is as follows: The bottom end of the monitoring column 14 contacts the ground. When the foundation at the support rod 1 settles, the bottom end of the monitoring column 14 presses against the ground, and the top end extends towards the upper movable cavity of the monitoring box 8, pushing the support plate 13 to rise. The support plate 13 drives the first electrode column 16 and the second electrode column 17 to rise synchronously. When the first electrode column 16 contacts the conductive sheet 18, the circuit is connected, and the alarm light 9 lights up, indicating that the foundation at the location has settled. When the monitoring column 14 continues to rise by pushing the support plate 13, the end of the second electrode column 17 moves on the sliding rheostat 19, changing the resistance of the circuit, thereby changing the brightness of the alarm light 9, so as to inform the staff of the relative degree of foundation settlement. Moreover, the monitoring boxes 8 in each direction work independently, which is conducive to ensuring the fault tolerance and accuracy of monitoring.

[0045] Example 2

[0046] Please see Figures 1-5A foundation settlement monitoring device for a template support frame includes a support rod 1 for supporting the template and a support cylinder 2 installed at the bottom of the support rod 1. The top of the support cylinder 2 has a slot 10, and a limiting sleeve 11 is fixedly installed on the top of the support cylinder 2. The support rod 1 passes through the limiting sleeve 11 and is inserted into the slot 10 for quick fixation. A battery box 3 is fixedly installed on the inner top wall of the support cylinder 2. The battery box 3 has a cuboid structure, and its interior is divided into four identical battery compartments 5 by a cross partition 4. Each battery compartment 5 is independently equipped with a battery 6. A matching cover 7 is installed at the bottom of the battery box 3. Monitoring boxes 8 are fixedly installed on the four side walls of the battery box 3. Four alarm lights 9 are fixedly installed on the top of the support cylinder 2 in an array.

[0047] Each monitoring box 8 is equipped with an alarm triggering mechanism. Four sets of alarm triggering mechanisms are electrically connected to four batteries 6. Alarm lights 9 and alarm triggering mechanisms are distributed in a one-to-one correspondence. Each alarm triggering mechanism includes a horizontal partition 12 fixedly installed in the middle of the inner wall of the monitoring box 8. The horizontal partition 12 divides the inner cavity of the monitoring box 8 into an upper movable cavity and a lower movable cavity. A support plate 13 is slidably installed in the lower movable cavity of the monitoring box 8. A monitoring post 14 is fixedly installed at the bottom of the support plate 13, sliding through the bottom of the monitoring box 8. A conductive pad 15 is fixedly installed at the top of the support plate 13. A first electrode post 16 and a second electrode post 17 are fixedly installed at the top two ends of the conductive pad 15, respectively. Both the first electrode post 16 and the second electrode post 17 extend through the horizontal partition 12 into the upper movable cavity. A conductive sheet 18 is fixedly installed on the inner wall of the upper movable cavity of the monitoring box 8. The conductive sheet 18 and... The first electrode post 16 is distributed accordingly. A sliding rheostat 19 is fixedly installed on the inner wall of the movable cavity of the monitoring box 8. The sliding rheostat 19 is adapted to the top of the second electrode post 17. The bottom end of the monitoring post 14 is in contact with the ground. When the foundation at the support rod 1 settles, the bottom end of the monitoring post 14 presses against the ground, and the top end extends towards the upper movable cavity of the monitoring box 8, pushing the support plate 13 to rise. The support plate 13 drives the first electrode post 16 and the second electrode post 17 to rise synchronously. When the first electrode post 16 contacts the conductive sheet 18, the circuit is connected, and the alarm light 9 lights up, indicating that the foundation at the location has settled. When the monitoring post 14 pushes the support plate 13 to continue rising, the end of the second electrode post 17 moves on the sliding rheostat 19, changing the resistance of the circuit, thereby changing the brightness of the alarm light 9, thus informing the staff of the relative degree of foundation settlement.

[0048] A support base 20 is fixedly installed at the bottom of the support cylinder 2. The circumferential cross-section of the support base 20 is a right trapezoid. The support base 20 increases the contact area with the ground and reduces the pressure on the contact surface with the ground, which is conducive to improving the stability of the support. The bottom end of the monitoring column 14 is flush with the bottom of the support base 20. Positioning columns 21 are vertically fixedly installed at both ends of the top of the tray 13. Both positioning columns 21 extend through into the upper movable cavity. Two spaced positioning tubes 22 are fixedly installed between the horizontal partition 12 and the inner top wall of the monitoring box 8. The two positioning columns 21 are slidably sleeved with the two positioning tubes 22 respectively. During the process of the tray 13 rising, the top of the positioning column 21 slides relative to the positioning tube 22, ensuring the stability of the tray 13 rising.

[0049] Four horizontal frames 25 arranged in a circular array are fixedly installed on the outer circumference of the support cylinder 2. A level 26 is fixedly installed on the inner bottom wall of the horizontal frame 25, which is conducive to the staff's intuitive observation of the horizontal state of the support cylinder 2 at the support rod 1 and the staff's multi-angle observation of the foundation settlement state of the template support frame. A protractor 27 is fixedly installed on the inner wall of the horizontal frame 25. A support shaft 28 is fixedly installed at the center of the protractor 27. A collar 29 is rotatably installed at the end of the support shaft 28. A pointer 30 and a cone 31 are on the outer circumference of the collar 29. The pointer 30 and the cone 31 are collinearly distributed. Under the action of the gravity of the cone 31, the pointer 30 keeps vertically collinear. When the foundation at the support rod 1 settles, the support cylinder 2 will tilt to the side with more severe settlement, which will cause the pointer 30 to deflect relative to the scale of the protractor 27. The angle of deflection can intuitively reflect the foundation settlement to a certain extent, which is convenient for the staff to observe.

[0050] The implementation principle of this embodiment is as follows: When the bottom end of the monitoring column 14 contacts the ground, and the foundation at the support rod 1 settles, the bottom end of the monitoring column 14 presses against the ground, and the top end extends towards the upper movable cavity of the monitoring box 8, pushing the support plate 13 upward. The support plate 13 drives the first electrode column 16 and the second electrode column 17 to rise synchronously. When the first electrode column 16 contacts the conductive sheet 18, the circuit is connected, the alarm light 9 lights up, indicating that the foundation at the location has settled. When the monitoring column 14 continues to rise by pushing the support plate 13, the end of the second electrode column 17... The movement of the sliding rheostat 19 changes the resistance of the circuit, thereby changing the brightness of the alarm light 9 to inform the staff of the relative degree of foundation settlement. At the same time, the pointer 30, under the gravity of the cone needle 31, keeps vertically collinear. When the foundation at the support rod 1 settles, the support cylinder 2 will tilt to the side of severe settlement, causing the pointer 30 to deflect relative to the scale of the protractor 27. The angle of deflection can intuitively reflect the foundation settlement situation to a certain extent, thus providing staff with prompts from multiple angles.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
