Description

Technical Field

[0001] The present invention relates to the technical field of the construction field, and in particular to a safety monitoring device and a safety monitoring method for corners of assembled buildings. Background Art

[0002] Prefabricated buildings refer to buildings that transfer a large amount of on-site work in traditional construction methods to factories, where building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in the factory, transported to the construction site, and assembled and installed on site through reliable connection methods.

[0003] Prefabricated buildings mainly include prefabricated concrete structures, steel structures, modern wooden structures, etc. Because they adopt standardized design, factory production, assembly construction, information management, and intelligent applications, they are representatives of modern industrialized production methods.

[0004] During the initial construction phase, the corners of prefabricated buildings are easily affected by other construction activities, causing changes in the angle of the corners. For example, when the prefabricated building is hoisted, it may collide with the installed components, causing the structure to shift, or it may be caused by vibration. Therefore, the existing technology requires multiple manual measurements for monitoring during the initial construction phase, increasing manpower expenditure. At the same time, corners are generally located at high places (such as the inner corners of composite slabs and walls), which also brings a series of safety hazards and is not conducive to large-scale construction. Summary of the Invention

[0005] The purpose of the present invention is to address the deficiencies in the prior art. Therefore, a safety monitoring device for prefabricated building corners is proposed. The specific solution is as follows: The safety monitoring device includes two measurement reference bodies, a continuous angle measurement unit for detecting the angles of the two measurement reference bodies, and an active installation unit for mounting the two measurement reference bodies on the surface of a structure. The two measurement reference bodies are hingedly connected to a connecting plate at one end near the building corner. When in use, the active installation unit mounts the two measurement reference bodies on the corresponding structure surface, and the continuous angle measurement unit is used to measure the angle change between the two measurement reference bodies.

[0006] The angle continuous measurement unit includes a brush mounted on a connecting plate and a resistance wire mounted on a corresponding measurement reference body, the brush and the resistance wire being in contact;

[0007] The safety monitoring device also includes a power supply for supplying power to the resistance wire and forming a closed loop with the brush, and an electric meter for displaying the current, voltage or resistance of the closed loop.

[0008] During use, the measuring reference body is installed on the surface of the corresponding structure at the corner through the active installation unit. After installation, the connecting plate and the measuring reference body form a certain angle. At this time, the brush will contact the corresponding point on the resistance wire. After power is turned on to form a closed loop, the value of the closed loop current or voltage or resistance can be obtained through the ammeter. Each point on the resistance wire represents an angle value. According to the resistance law R=ρL / S, the value can be converted into a corresponding inclination angle. The angle of the corner can be obtained according to the two inclination angles of the two measuring reference bodies and the connecting plate.

[0009] Based on the above embodiment, the following improvements are made. In order to accurately measure the angles at the corners of prefabricated floor panels and prefabricated walls, and at the corners between prefabricated walls, and to overcome the problem that the tilt angle of the prefabricated floor panels and / or prefabricated walls affects the angle measurement accuracy when they are offset, and to enable quick adjustment during the installation of prefabricated walls and prefabricated floor panels, without the need for manual multiple measurements of the verticality of the wall and the tilt angle of the wall along the length direction, and the horizontality of the floor panels, thereby optimizing the construction steps, the following improvements are made:

[0010] A structural surface inclination angle measuring unit is installed on each of the two measurement reference bodies. The structural surface inclination angle measuring unit includes a measuring plate and a reference plate. The measuring plate is installed on the measurement reference body. Three hinge shafts 1 are evenly installed circumferentially on the measuring plate. A hinge shaft 2 corresponding to the position of the hinge shaft 1 is installed on the reference plate. The ends of the hinge shaft 1 and the hinge shaft 2 are both provided with connecting shafts. The two connecting shafts at the corresponding ends of the hinge shaft 1 and the hinge shaft 2 are connected by a connecting rod, and the lengths of all the connecting rods are the same.

[0011] An angle continuous measurement structure 1 is installed at the rotation node of the articulated shaft 1 and the measuring plate. The angle continuous measurement structure 1 has the same structure as the angle continuous measurement unit. A resistance wire of the angle continuous measurement structure is installed on the measuring plate, and a brush in contact with the resistance wire is installed on the articulated shaft 1.

[0012] An angle continuous measurement structure 2 is installed at the rotation node of the connecting rod and the connecting shaft. The angle continuous measurement structure 2 has the same structure as the angle continuous measurement unit. A resistance wire of the angle continuous measurement structure is installed on the connecting rod, and a brush in contact with the resistance wire is installed on the connecting shaft.

[0013] The monitoring personnel can obtain the deflection angle of the connecting rod and the deflection angle of the hinge axis one based on the angle continuous measurement structure one and the angle continuous measurement structure two, obtain the distance between the hinge axis one and the hinge axis two based on the trigonometric function, and obtain the relative three-dimensional coordinates of the midpoint of the hinge axis one relative to the coordinate point provided by the three-dimensional coordinate sensor. The inclination angle between the plane composed of the three sets of three-dimensional coordinates and the horizontal plane can be obtained. The inclination angle can be the horizontal deviation angle of the floor panel, the vertical deviation angle of the wall, or the deviation angle between the wall along the length direction and the predetermined direction required by the drawing.

[0014] Based on the above embodiment, the following improvements are made: the active mounting unit includes a waist-shaped hole opened along the length direction of the measuring reference body, a base is provided in the waist-shaped hole and a groove is provided on the base, a slider is slidably fitted in the groove and a ball group is provided on the side of the slider opposite to the groove, and the slider is fixed to the surface of the structure by an anchor bolt.

[0015] Based on the above embodiment, the following improvements are made: the measuring reference body includes a connecting part and a rotating part, the connecting part is used to connect the connecting plate, the rotating part is used to install the structural surface inclination angle measuring unit, the connecting part is used to install the active mounting unit, the connecting part and the rotating part are connected by a rotating shaft, and the rotating part is provided with a leveling bolt suitable for the rotating part to be arranged parallel to the surface of the structure.

[0016] Based on the above embodiment, the following improvements are made. The connecting plate includes two hinged monomers, one and two. Monomer one is connected to a limiting plate, monomer two is provided with a limiting groove adapted to the limiting plate, and monomer two is provided with a hidden groove for socketing monomer one.

[0017] Based on the above embodiment, the following improvement is made: the second monomer is provided with a locking member for locking the first monomer in the hidden groove.

[0018] Based on the above embodiment, the following improvement is made: the resistance wire is arranged in a ring and separated by an insulating block, and each point on the resistance wire corresponds to an inclination angle;

[0019] The measuring reference body, measuring plate and connecting rod are all provided with limiting balls suitable for protecting the brushes.

[0020] Based on the above embodiment, the following improvement is made: the electric meter is a voltmeter, a resistance meter, or an ammeter, or is replaced by a device that can remotely transmit the current voltage / current / resistance conditions.

[0021] Based on the above embodiment, the following improvements are made. The safety monitoring device also includes a data processing module, which feeds back the received current voltage / current / resistance data to the client based on the internally implanted reference data. The reference data includes a database of angles corresponding to each voltage / current / resistance data.

[0022] A safety monitoring method for a safety monitoring device at a corner of an assembled building, the safety monitoring steps are as follows:

[0023] When safely monitoring the sun corner:

[0024] Step 1: Rotate the first unit inward into the second unit and lock it in place through the locking groove. Place the two measuring reference bodies on the surface of the structure at the building's outer corner. Install the connecting part on the structure surface through the anchor bolts and active mounting units. Use the leveling bolts on the rotating part to arrange the rotating part parallel to the structure surface.

[0025] Step 2: Turn on the power supply of the angle measurement unit and the structural surface inclination angle measurement unit. The brushes and corresponding points on the resistance wire will contact to form a closed circuit. The angle value per unit time is continuously collected according to the current voltage / current / resistance displayed on the meter or sent remotely. The collected angle value can be fed back to the monitoring personnel in real time through the data processing module.

[0026] Step 3: If the structure deviates during other construction, the connection part will slide along the waist hole through the ball group and groove due to the fixation of the slider and anchor bolt, forcing the angle between the connection plate and the measurement reference body to change. The monitoring personnel can intuitively judge the angle change value based on the current voltage / current / resistance displayed by the meter or sent remotely, which facilitates the correction of the structure with internal angle;

[0027] The angle measurement process of the structural surface inclination angle measurement unit is as follows:

[0028] Since the leveling bolts place the rotating part parallel to the surface of the structure, the tilt angle of the rotating part is the tilt angle of the surface of the structure;

[0029] The deflection angles of the respective hinge axis 1 and connecting rod are obtained according to the three sets of angle measurement structures 1 and 2. The three-dimensional coordinates of the hinge axis 1 relative to the respective hinge axis 2 can be obtained according to the length of the connecting rod and the deflection angles of the hinge axis 1 and the connecting rod. The reference plate will always remain horizontal under the action of the combined structure composed of the hinge axis 1, the connecting rod, and the hinge axis 2, which is evenly distributed in the circumference. That is, the reference plate serves as the reference surface, and the inclination angle of the surface composed of the three three-dimensional coordinates relative to the reference surface is the inclination angle of the structure surface.

[0030] When safely monitoring a concave corner:

[0031] Step 1: Place the two measuring reference bodies on the surface of the structure at the inner corner of the building, install the connecting part on the surface of the structure using anchor bolts and active installation units, and use the leveling bolts on the rotating part to arrange the rotating part parallel to the surface of the structure;

[0032] Step 2: Turn on the power supply of the angle measurement unit and the structural surface inclination angle measurement unit. The brushes and corresponding points on the resistance wire will contact to form a closed circuit. The angle value per unit time is continuously collected according to the current voltage / current / resistance displayed on the meter or sent remotely. The collected angle value can be fed back to the monitoring personnel in real time through the data processing module.

[0033] Step 3: If the structure deviates after construction, the connection part will slide along the waist hole through the ball group and groove due to the fixation of the slider and anchor bolt, forcing the angle between the connection plate and the measurement reference body to change. The monitoring personnel can intuitively judge the angle change value based on the current voltage / current / resistance displayed by the meter or sent remotely, which facilitates the correction of the structure with internal angle;

[0034] The angle measurement process of the structural surface inclination angle measurement unit is as follows:

[0035] Since the leveling bolts place the rotating part parallel to the surface of the structure, the tilt angle of the rotating part is the tilt angle of the surface of the structure;

[0036] According to the three sets of angle measurement structures 1 and 2, the deflection angle of the respective hinge axis 1 and the deflection angle of the connecting rod are obtained respectively. According to the length of the connecting rod and the deflection angle of the hinge axis 1 and the deflection angle of the connecting rod, the three-dimensional coordinates of the hinge axis 1 relative to the respective hinge axis 2 can be obtained. The reference plate will always remain horizontal under the action of the three sets of circumferentially evenly distributed combined structures composed of the hinge axis 1, the connecting rod, and the hinge axis 2. That is, the reference plate serves as the reference plane, and the inclination angle of the surface composed of the three three-dimensional coordinates relative to the reference plane is the inclination angle of the surface of the structure.

[0037] Compared with the prior art, the present invention has the following beneficial effects: the measuring reference body is installed on the surface of the corresponding structure at the corner through an active installation unit. After installation, the connecting plate and the measuring reference body form a certain angle. At this time, the brush will contact the corresponding point on the resistance wire. After power is turned on to form a closed loop, the value of the closed loop current / voltage / resistance can be obtained through the electric meter. Each point on the resistance wire represents an angle value. According to the resistance law R=ρL / S, the value can be converted into a corresponding deflection angle. According to the two deflection angles of the two measuring reference bodies and the connecting plate, the angle of the corner can be obtained. The device can be used to continuously monitor angle changes and optimize the angle monitoring steps.

[0038] The present invention is suitable for accurately measuring the angles at the corners of prefabricated floor panels and prefabricated walls, and at the corners between prefabricated walls, and overcomes the problem that the tilt angle of the prefabricated floor panels and / or prefabricated walls affects the angle measurement accuracy when the prefabricated floor panels and / or prefabricated walls are offset. At the same time, it can also reduce the prefabricated walls and prefabricated floor panels. Quick adjustment can be made during installation without manually measuring the verticality of the wall and the tilt angle of the wall along the length direction and the horizontality of the floor panels multiple times, thereby optimizing the construction steps. A structural surface tilt angle measurement structure is designed. According to three groups of angle measurement structures 1 and 2, the deflection angle of each hinge axis 1 and the deflection angle of the connecting rod are respectively obtained. According to the length of the connecting rod and the deflection angle of the hinge axis 1 and the deflection angle of the connecting rod, the relative coordinates of the hinge axis 1 relative to each hinge axis 2 can be obtained. The reference plate will always remain horizontal under the action of the combined structure composed of the three groups of hinge axis 1, the connecting rod, and the hinge axis 2, which are evenly distributed in the circumferential direction. That is, the reference plate serves as a reference surface, and the tilt angle of the surface composed of the three relative coordinates relative to the reference surface is the tilt angle of the structure surface.

[0039] The present invention also takes into account the monitoring of the external angle. By improving the connecting plate to be composed of a single body one, a single body two, a limit plate and other structures, the single body one is rotated inwardly into the single body two and locked and fixed through the locking groove, and the two measuring reference bodies are attached to the surface of the structure at the external angle of the building. The connecting part is installed on the surface of the structure through the anchor bolt and the active installation unit, and the leveling bolt on the rotating part is suitable for arranging the rotating part parallel to the surface of the structure.

[0040] The device can be installed after the installation of walls and floor panels but before fine-tuning. It can also facilitate the fine-tuning of parameters such as the horizontality and verticality of walls and floor panels, and optimize construction steps. The device can be used to continuously collect angle values ​​to achieve continuous monitoring functions, reduce safety risks, and is suitable for large-scale construction.

[0053] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0054] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0055] Example 1, a safety monitoring device for the corners of an assembled building, includes two measuring reference bodies 1, an angle continuous measurement unit for detecting the angles of the two measuring reference bodies 1, and an active installation unit for installing the two measuring reference bodies 1 on the surface of a structure. The two measuring reference bodies 1 are hingedly connected to a connecting plate 2 at one end near the corner of the building. When in use, the connecting plate 2 can avoid the installation position of the post-casting strip formwork. The active installation unit installs the two measuring reference bodies 1 on the surface of the corresponding structure, and the angle continuous measurement unit is used to measure the angle change between the two measuring reference bodies 1.

[0056] The active mounting unit includes a waist-shaped hole 12 extending along the length of the measuring reference body 1. Both ends of the waist-shaped hole 12 are provided with a base 13, and the base 13 is provided with a groove 14. A slider 15 slides in the groove 14, and a ball group 16 is provided on the side of the slider 15 opposite the groove 14. The slider 15 is fixed to the surface of the structure via an anchor bolt. When a collision causes a small offset of the corresponding structure, since the measuring reference body 1 on one side does not offset perpendicularly to the corresponding structure, the other measuring reference body 1 will move in the opposite direction relative to the offset structure under the action of the connecting plate 2. Since the anchor bolt and slider 15 are fixedly arranged, the groove 14 and slider 15 will move along the length of the base 13 via the ball group 16, and the angle between the two structural surfaces will change.

[0057] The angle continuous measurement unit includes a brush 4 installed on the connecting plate 2 and a resistance wire 3 installed on the corresponding measurement reference body 1, and the brush 4 is in contact with the resistance wire 3; the safety monitoring device also includes a power supply 5 that supplies power to the resistance wire 3 and forms a closed loop with the brush 4, and an ammeter for displaying the closed loop current / voltage / resistance.

[0058] During use, the measuring reference body 1 is installed on the surface of the structure corresponding to the corner through the active installation unit. After installation, the connecting plate 2 and the measuring reference body 1 form a certain angle. At this time, the brush 4 will contact the corresponding point on the resistance wire 3. After the power is turned on to form a closed loop, the value of the closed loop current, voltage or resistance can be obtained through the ammeter. Each point on the resistor 3 represents an angle value. According to the resistance law R=ρL / S, the value can be converted into a corresponding tilt angle. The angle of the corner can be obtained according to the two tilt angles of the two measuring reference bodies 1 and the connecting plate 2. The device can maintain continuous measurement. Even if the hoist collides and causes a small distance offset of the structure, the existence of the active installation unit can also enable its angle continuous measurement unit to continue to work and complete the angle data collection per unit time. An alarm device can also be added. Once the tilt angle exceeds the set threshold, the alarm device will start to sound an alarm.

[0059] To accommodate measurements of exterior corners, the connecting plate 2 comprises two hinged units: Unit 1 20 and Unit 2 21. Unit 1 20 is connected to a limit plate 22, and Unit 2 21 is provided with a limit slot 23 that mates with the limit plate 22. Unit 2 21 is provided with a hidden slot 24 for receiving and inserting Unit 1 20, and a locking member 25 is provided on Unit 2 21 to lock Unit 1 20 within the hidden slot 24. When used for interior corners, the limit plate 22 and limit slot 23 mate, allowing Unit 1 20 to unfold from the hidden slot 24, forming a linear configuration with Unit 1 20 and Unit 2 21. When used for exterior corners, Unit 1 20 is concealed within the hidden slot 24 and secured therewith via locking bolts.

[0060] To accurately measure the angles at the corners of prefabricated floor panels and prefabricated walls, and at the corners between prefabricated walls, and to overcome the problem of angle measurement accuracy being affected by the tilt angle caused by the offset of prefabricated floor panels and / or prefabricated walls, the following improvements have been made:

[0061] Both of the measuring reference bodies 1 are equipped with a structural surface inclination angle measuring unit, which includes a measuring plate 6 and a reference plate 7. The measuring plate 6 is installed on the measuring reference body 1, and three hinge shafts 8 are evenly installed circumferentially on the measuring plate 6. The reference plate 7 is equipped with a hinge shaft 2 9 arranged corresponding to the position of the hinge shaft 1 8. The ends of the hinge shaft 1 8 and the hinge shaft 2 9 are both provided with connecting shafts 11. The two connecting shafts 11 at the corresponding ends of the hinge shaft 1 8 and the hinge shaft 2 9 are connected by a connecting rod 10, and the lengths of all the connecting rods 10 are the same; through the combined structure composed of three groups of connecting rods 10, the hinge shaft 2 9, and the hinge shaft 1 8, the reference plate 7 will always be in a horizontal state (for the floor panel) under the action of its combined structure, and is used as a reference surface.

[0062] An angle continuous measurement structure 1 is installed at the rotation node of the articulated shaft 8 and the measuring plate 6. The angle continuous measurement structure 1 has the same structure as the angle continuous measurement unit. The resistance wire 3 of the angle continuous measurement structure 1 is installed on the measuring plate 6, and the brush 4 in contact with the resistance wire 3 is installed on the articulated shaft 8; the rotation node of the articulated shaft 2 9 and the reference plate 7 can also be equipped with an angle continuous measurement structure 3. The angle continuous measurement structure 3 has the same structure as the angle continuous measurement unit. The resistance wire 3 of the angle continuous measurement structure 3 is installed on the reference plate 7, and the brush 4 in contact with the resistance wire 3 is installed on the articulated shaft 2 9.

[0063] An angle continuous measurement structure 2 is installed at the rotation node of the connecting rod 10 and the connecting shaft 11. The angle continuous measurement structure 2 has the same structure as the angle continuous measurement unit. The resistance wire 3 of the angle continuous measurement structure 2 is installed on the connecting rod 10, and the brush 4 in contact with the resistance wire 3 is installed on the connecting shaft 11.

[0064] According to the three sets of angle measurement structures 1 and 2, the deflection angles of the respective hinge shafts 8 and the connecting rods 10 are obtained respectively. According to the length of the connecting rod 10 and the deflection angles of the hinge shaft 8 and the connecting rod 10, the relative coordinates of the hinge shaft 8 relative to the respective hinge shafts 2 9 can be obtained. Under the action of the three sets of circumferentially evenly distributed combined structures consisting of the hinge shaft 1 8, the connecting rod 10, and the hinge shaft 2 9, the reference plate 7 will always maintain a horizontal state (relative to the floor panel) or a vertical state parallel to the predetermined direction required by the drawing (relative to the wall). That is, with the reference plate as the reference plane, the inclination angle of the surface formed by the three-dimensional coordinates of the centers of the three hinge shafts 8 relative to the reference plane is the inclination angle of the surface of the structure.

[0065] The measuring reference body 1 includes a connecting part 17 and a rotating part 18. The connecting part 17 is used to connect the connecting plate 2, and the rotating part 18 is used to install the structural surface inclination angle measurement unit. The connecting part 17 is used to install the active installation unit. The connecting part 17 and the rotating part 18 are connected by a rotating shaft. The rotating part 18 is provided with a leveling bolt 19 suitable for the rotating part 18 to be arranged parallel to the surface of the structure.

[0066] The measuring reference body 1 is divided into two parts. The connecting part 17 is installed on the surface of the structure through an active mounting unit. The rotating part 18 is appropriately rotated and fixed to the surface of the structure through the leveling bolts 19, so that the rotating part 18 and the surface of the structure are arranged parallel. The inclination angle of the rotating part 18 is the inclination angle of the surface of the structure, that is, the inclination angle of the measuring plate 8, that is, the inclination angle of the surface formed by the centers of the three hinge shafts 8 relative to the reference plate 7.

[0067] In one of the above embodiments, the resistance wire 3 is arranged in a ring and separated by an insulating block 26, and each point on the resistance wire 3 corresponds to an inclination angle; the measuring reference body 1, the measuring plate 6, and the connecting rod 10 are all provided with limiting balls 27 suitable for protecting the brush 4.

[0068] In one of the above embodiments, the electric meter is a voltmeter, a resistance meter, or an ammeter. In some cases, it can be replaced by a device that can remotely transmit the current voltage / current / resistance conditions.

[0069] In one of the above embodiments, the safety monitoring device also includes a data processing module, which feeds back the received current voltage / current / resistance data to the client based on the internally implanted reference data. The reference data includes a database of angles corresponding to each voltage / current / resistance data, which can realize intuitive angle monitoring.

[0070] A safety monitoring method for a safety monitoring device at a corner of an assembled building, the safety monitoring steps are as follows:

[0071] When safely monitoring the sun corner:

[0072] Step 1: Rotate the first unit 20 inward into the second unit 21 and lock it in place through the locking groove. Attach the two measurement reference bodies 1 to the surface of the structure at the building's outer corner. Install the connecting portion 17 on the structure surface using anchor bolts and active mounting units. Use the leveling bolts 19 on the rotating portion 18 to position the rotating portion 18 parallel to the structure surface.

[0073] Step 2: Turn on the power supply 5 of the angle measurement unit and the structural surface inclination angle measurement unit, and the brush 4 contacts the corresponding points on the resistance wire 3 to form a closed circuit. According to the current voltage / current / resistance displayed by the meter or sent remotely, the angle value per unit time is continuously collected. The collected angle value can be fed back to the monitoring personnel in real time according to the data processing module;

[0074] Step 3: If the structure deviates during other construction, the connection part 17 will slide along the waist-shaped hole 12 through the ball group 16 and the groove 14 due to the fixation of the slider 15 and the anchor bolt, forcing the angle between the connecting plate 2 and the measurement reference body 1 to change. The monitoring personnel can intuitively judge the angle change value based on the current voltage / current / resistance displayed by the electric meter or remotely sent, which facilitates the correction of the structure with a concave angle;

[0075] The angle measurement process of the structural surface inclination angle measurement unit is as follows:

[0076] Since the leveling bolts 19 arrange the rotating portion 18 parallel to the surface of the structure, the tilt angle of the rotating portion 18 is the tilt angle of the surface of the structure;

[0077] The deflection angles of the respective hinge shafts 8 and the connecting rods 10 are obtained according to the three sets of angle measurement structures 1 and 2. The relative coordinates of the hinge shafts 8 relative to the respective hinge shafts 2 9 can be obtained according to the length of the connecting rod 10 and the deflection angles of the hinge shafts 8 and 10. The reference plate 7 will always remain horizontal under the action of the combined structure composed of the hinge shafts 8, the connecting rods 10, and the hinge shafts 2 9, which are evenly distributed in the circumferential direction. That is, the reference plate 7 serves as a reference plane, and the inclination angle of the surface composed of the three relative coordinates relative to the reference plane is the inclination angle of the surface of the structure.

[0078] When safely monitoring a concave corner:

[0079] Step 1: Place the two measuring reference bodies 1 on the surface of the structure at the inner corner of the building. Install the connecting part 17 on the surface of the structure using anchor bolts and active mounting units. Use the leveling bolts 19 on the rotating part 18 to arrange the rotating part 18 parallel to the surface of the structure.

[0080] Step 2: Turn on the power supply 5 of the angle measurement unit and the structural surface inclination angle measurement unit, and the brush 4 contacts the corresponding points on the resistance wire 3 to form a closed circuit. According to the current voltage / current / resistance displayed by the meter or sent remotely, the angle value per unit time is continuously collected. The collected angle value can be fed back to the monitoring personnel in real time according to the data processing module;

[0081] Step 3: If the structure deviates after construction, the connection part 17 will slide along the waist-shaped hole 12 through the ball group 16 and the groove 14 due to the fixation of the slider 15 and the anchor bolt, forcing the angle between the connecting plate 2 and the measurement reference body 1 to change. The monitoring personnel can intuitively judge the angle change value based on the current voltage / current / resistance displayed by the electric meter or sent remotely, which facilitates the correction of the structure with a concave angle;

[0082] The angle measurement process of the structural surface inclination angle measurement unit is as follows:

[0083] Since the leveling bolts 19 arrange the rotating portion 18 parallel to the surface of the structure, the tilt angle of the rotating portion 18 is the tilt angle of the surface of the structure;

[0084] According to the three sets of angle measurement structures 1 and 2, the deflection angles of the respective hinge shafts 8 and the connecting rods 10 are obtained respectively. According to the length of the connecting rod 10 and the deflection angles of the hinge shaft 8 and the connecting rod 10, the relative coordinates of the hinge shaft 8 relative to the respective hinge shafts 2 9 can be obtained. Under the action of the three sets of circumferentially evenly distributed combined structures consisting of the hinge shaft 1 8, the connecting rod 10, and the hinge shaft 2 9, the reference plate 7 will always maintain a horizontal state (relative to the floor panel) or a vertical state parallel to the predetermined direction required by the drawing (relative to the wall). That is, the reference plate 7 serves as a reference plane, and the inclination angle of the surface composed of the three relative coordinates relative to the reference plane is the inclination angle of the surface of the structure.

The replacement may be a replacement of a portion of a structure, device, or method step, or it may be a complete technical solution. Any equivalent replacement or modification based on the technical solution and inventive concept of the present invention shall be covered by the scope of protection of the present invention.
