Abstract
Description
Technical Field
[0001] The present application relates to the field of displacement monitoring and early warning, and in particular, to a displacement monitoring and early warning device for engineering supervision. Background Art
[0002] Shear wall, also known as wind-resistant wall, earthquake-resistant wall or structural wall, is the wall in a house or structure that mainly bears horizontal and vertical loads caused by wind loads or earthquakes to prevent structural shear damage. It is also called earthquake-resistant wall and is generally made of reinforced concrete.
[0003] In order to ensure the safety of high-rise buildings, the displacement of shear walls must be guaranteed within a certain range. At the same time, during the construction of high-rise buildings, the displacement of the shear walls at the bottom must be monitored to ensure the safety of the buildings. Under the existing technology, engineering supervisors use portable measuring tools to observe the displacement of shear walls. Each monitoring requires carrying tools and performing detection operations. However, high-rise buildings have a large number of floors, and it takes a lot of time to detect the shear walls of each floor of the building one by one, which greatly increases the workload of engineering supervisors. Therefore, a technical measure is proposed to solve the problem that high-rise buildings have a large number of floors, and engineering supervisors perform displacement detection on each floor of the building one by one, which takes a lot of time, greatly increasing the workload of engineering supervisors. Utility Model Content
[0004] The content of this application is used to introduce concepts in a brief form, which will be described in detail in the detailed implementation section below. The content of this application is not intended to identify the key features or essential features of the technical solution claimed for protection, nor is it intended to limit the scope of the technical solution claimed for protection.
[0005] In order to solve the technical problems mentioned in the above background technology part, some embodiments of the present application provide a displacement monitoring and early warning device for engineering supervision, including vertical plates, wherein the vertical plates are provided in two groups, and the lower ends of the two groups of vertical plates are connected to a base plate, and the lower ends of the vertical plates are symmetrically distributed on the upper surface of the base plate, and the upper ends of the vertical plates are connected to a box body, and a slide groove is provided on the surface of the box body, and a monitoring component is installed on the box body, and the slide groove is slidably adapted to the monitoring component. Thanks to the arrangement of the marking rod and the monitoring component, the distance between the marking rod and the warning line on the middle plate can be used to conveniently judge whether the displacement distance of the shear wall is within the allowable range, and it is very intuitive, and there is no need to measure the displacement distance every time, which reduces the time for engineering supervision monitoring and reduces the workload of engineering supervision.
[0006] Furthermore, a level is installed at the center of the upper surface of the base plate, and a plurality of evenly distributed support plates are provided at the lower part of the base plate. Thanks to the setting of the level, the base plate can be easily adjusted to a horizontal state, thereby ensuring the horizontal state of the monitoring component and improving the monitoring accuracy.
[0007] Furthermore, two groups of evenly distributed limiting grooves are provided on a side of the box body away from the slide groove, and a marking rod is installed in the middle position of the box body slide groove.
[0008] Furthermore, the monitoring component includes a spring, and there are multiple groups of springs. The multiple groups of springs are fixedly installed inside the box body, the other end of the spring is connected to an extrusion plate, the center position of the extrusion plate on the side away from the spring is connected to a connecting rod, the other end of the connecting rod is connected to a connecting plate, and the end of the connecting plate away from the connecting rod is connected to an intermediate plate.
[0009] Furthermore, the middle plate is slidably connected to the slide groove, the marking rod is in sliding contact with the upper surface of the middle plate, a scale zero line is provided at the center position of the upper surface of the middle plate, and two groups of symmetrically distributed warning lines are provided on the upper surface of the middle plate.
[0010] Furthermore, the monitoring component also includes a slider, a side of the slider is fixedly connected to the extrusion plate, a side of the slider away from the extrusion plate is connected to a side plate, the side plate is threadedly connected to a screw, and the screw is connected to a knob.
[0011] Furthermore, one end of the screw rod away from the knob is rotatably connected to a clamping plate, and a side surface of the clamping plate is in sliding contact with an outer surface of one side of the box body where a limiting groove is provided.
[0012] Furthermore, the slider is slidably matched with the limiting groove. Thanks to the arrangement of the slider and the limiting groove, it is convenient to limit the side plate and avoid the angle of the side plate from being deflected.
[0013] The utility model can judge whether the displacement distance of the shear wall is within the allowable range by setting the marking rod and the monitoring component and the distance between the marking rod and the warning line on the middle plate. The utility model is very intuitive and does not need to measure the displacement distance every time, thus reducing the time of engineering supervision and monitoring and the workload of engineering supervision. When the shear wall is displaced, the clamping plate is driven to move horizontally, the horizontal movement of the clamping plate drives the middle plate to move horizontally, and the horizontal movement of the middle plate drives the scale zero line and the warning line to move horizontally (under normal circumstances, the scale zero line is aligned with the marking rod). When the marking rod is observed to move to the warning line, the maximum allowable displacement value is reached.
[0014] By setting the level, the base plate can be easily adjusted to a horizontal state, thereby ensuring the horizontal state of the monitoring components and improving the monitoring accuracy. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the monitoring component 2 includes a spring 207, and there are multiple groups of springs 207. The multiple groups of springs 207 are fixedly installed in the box body 6. The other end of the spring 207 is connected to an extrusion plate 206. The center position of the extrusion plate 206 on the side away from the spring 207 is connected to a connecting rod 203. The other end of the connecting rod 203 is connected to a connecting plate 205. The end of the connecting plate 205 away from the connecting rod 203 is connected to an intermediate plate 204. The intermediate plate 204 is slidably connected to the slide groove 7. The marking rod 9 is in sliding contact with the upper surface of the intermediate plate 204. A scale zero line 210 is provided at the center of the surface, and two sets of symmetrically distributed warning lines 212 are provided on the upper surface of the middle plate 204. The monitoring component 2 also includes a slider 202, and the side of the slider 202 is fixedly connected to the extrusion plate 206. The side of the slider 202 away from the extrusion plate 206 is connected to a side plate 208, and the side plate 208 is threadedly connected to a screw 209, and the screw 209 is connected to a knob 201. The end of the screw 209 away from the knob 201 is rotatably connected to a clamping plate 211, and the side of the clamping plate 211 is connected to the outer side of the box body 6 on the side where the limiting groove 8 is provided. The surface is in sliding contact, the slider 202 is slidably adapted to the limit groove 8, the knob 201 is turned to drive the screw 209 to rotate, the screw 209 rotates to drive the clamping plate 211 to move horizontally, the clamping plate 211 moves horizontally to press against the two sides of the shear wall, and when the shear wall is displaced, the clamping plate 211 moves horizontally, the clamping plate 211 moves horizontally to drive the screw 209 and the side plate 208 to move horizontally, the side plate 208 moves horizontally to drive the slider 202 to slide along the limit groove 8, and when the slider 202 slides, it drives the extrusion plate 206 to move horizontally, and the extrusion plate 206 moves horizontally. The connecting rod 203 is driven to move horizontally, and the spring 207 is compressed when the connecting rod 203 moves horizontally. The horizontal movement of the connecting rod 203 drives the connecting plate 205 to move horizontally. The horizontal movement of the connecting plate 205 drives the middle plate 204 to move horizontally. The horizontal movement of the middle plate 204 drives the scale zero line 210 and the warning line 212 to move horizontally (under normal circumstances, the scale zero line 210 is aligned with the marking rod 9). When it is observed that the marking rod 9 moves to the warning line 212, the maximum allowable displacement is reached. At this time, remedial measures should be taken to ensure the safety of the building.
[0031] Working principle: When using this device to monitor the displacement of the shear wall, select a monitoring device with different positions of the warning line 212 according to the different settings of the shear wall (except for the different positions of the warning line 212, the rest of the monitoring device has the same structure. According to the "Technical Code for Concrete Structures of High-rise Buildings", various structural forms are divided when specifying the elastic inter-layer displacement limit of the structure. For high-rise buildings with a height of no more than 150 meters, the ratio of the maximum inter-layer displacement to the floor height for the frame-shear wall and plate-column shear wall structure system is 1 / 800, and for the shear wall structure system is 1 / 1000. According to the "Residential Design Code", the floor height of ordinary residential buildings should be 2.80 meters, and the maximum allowable horizontal displacement of the frame-shear wall and plate-column shear wall structure is 5.09 mm, and the shear wall structure is 2.80 mm. Therefore, the maximum horizontal displacement of the shear wall can be observed by horizontal movement of the marking rod 9);
[0032] The device is then installed. During installation, the bottom plate 1 is placed close to the shear wall, and the levelness of the bottom plate 1 is observed through the leveler 4 (ensuring that the leveler 4 is at the center of the bottom plate 1). Then, the monitoring component 2 is used to monitor the shear wall. Specifically, the knob 201 is turned to drive the screw 209 to rotate, and the rotation of the screw 209 drives the clamping plate 211 to move horizontally. The clamping plate 211 moves horizontally and presses against both sides of the shear wall. When the shear wall is displaced, it drives the clamping plate 211 to move horizontally. The horizontal movement of the clamping plate 211 drives the screw 209 and the side plate 208 to move horizontally. The horizontal movement of the side plate 208 drives the slider 202 to slide along the limit groove 8. When block 202 slides, it drives the extrusion plate 206 to move horizontally, and the horizontal movement of the extrusion plate 206 drives the connecting rod 203 to move horizontally. When the connecting rod 203 moves horizontally, the spring 207 is compressed. The horizontal movement of the connecting rod 203 drives the connecting plate 205 to move horizontally. The horizontal movement of the connecting plate 205 drives the middle plate 204 to move horizontally. The horizontal movement of the middle plate 204 drives the scale zero line 210 and the warning line 212 to move horizontally (under normal circumstances, the scale zero line 210 is aligned with the marking rod 9). When it is observed that the marking rod 9 moves to the warning line 212, the maximum allowable displacement is reached. At this time, remedial measures should be taken to ensure the safety of the building.
