Description

Technical Field

[0001] This invention relates to the field of structural deformation monitoring technology, specifically to a monitoring device and its method of use that can simultaneously monitor the opening amount of structural joints and the amount of misalignment. Background Technology

[0002] During use, above-ground or underground buildings and structures are affected by human or natural factors such as surrounding construction, rock loads, operational loads, natural precipitation, earthquakes, and explosions. This can cause uneven settlement or soil migration in the foundation, leading to deformation of the main structure. Improper handling can affect the normal use of the building or structure and even cause safety accidents. Continuous monitoring of structural joint deformation is a crucial means of tracking and evaluating the safety and comfort of the structure.

[0003] Currently, structural joint deformation monitoring is generally conducted manually using tools such as tape measures, vernier calipers, or laser rangefinders. However, this method often suffers from problems such as inconvenience in operation, poor accuracy, insufficient timeliness, and high cost. Furthermore, existing measurement methods typically measure the opening and misalignment of the structural joint separately, resulting in a large workload and cumbersome operation. Therefore, a convenient, efficient, accurate, and real-time structural joint deformation monitoring device and method are needed. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides an automated monitoring device and method for detecting the opening and misalignment of structural joints in buildings and structures. This method overcomes the technical limitations of existing joint deformation measurement tools and methods, which suffer from single-function limitations, low measurement accuracy, low efficiency, and high cost.

[0005] The technical solution of the present invention is as follows:

[0006] A structural joint deformation monitoring device includes a left structure, a right structure, a device base plate, fixing bolts, splicing screws, a micrometer measuring rod, a vertical micrometer instrument panel, and a horizontal micrometer instrument panel. The left and right structures are adjacent structures on the same building / structure, with a structural joint between them. The device base plate is respectively installed on the surface of the left and right structures. The fixing bolts fix the device base plate to the left and right structures respectively. The left structure has a vertical micrometer instrument panel, and the right structure has a horizontal micrometer instrument panel. The micrometer measuring rod passes through both the vertical and horizontal micrometer instrument panels. The micrometer measuring rod in the vertical micrometer instrument panel is parallel to the structural joint. The micrometer measuring rod in the horizontal micrometer instrument panel is perpendicular to the structural joint. The micrometer measuring rod in the horizontal micrometer instrument panel is connected to the vertical micrometer instrument panel via splicing screws. The horizontal micrometer instrument panel is vertically connected to the right structure via splicing screws.

[0007] Preferably, the base plate of the device is made of steel plate of a certain thickness, but is not limited to steel plate, and a certain number of bolt holes are provided on the steel plate. Depending on the specific structure, the base plate can be fixed to the structure by means of anchoring adhesive or expansion bolts.

[0008] Preferably, when using expansion bolts to fix the device base plate to the structure, expansion bolts that match the pre-drilled bolt holes on the device base plate are required.

[0009] Preferably, the micrometer measuring rod is a metal rod that can freely extend and retract along the axial direction on the micrometer and whose extension and retraction can be sensed. It is connected to the splicing screw or the base nut by a fixing nut, thereby being relatively fixed to the structure. When the structure deforms, it will cause the measuring rod to extend and retract relative to the micrometer. The micrometer reflects the deformation of the structure based on the accurately measured deformation of the measuring rod.

[0010] Preferably, the vertical micrometer panel is the core component of the micrometer, which includes a measuring rod extension and deformation sensing module, a deformation digital display module, a temperature and humidity measurement module, a wireless communication and transmission module, a battery module, and a metal protective shell. A base nut 4 is fixed on the horizontal side of the metal shell to facilitate the fixing of the measuring rod of the horizontal micrometer to it.

[0011] Furthermore, in the aforementioned structural joint deformation monitoring device, the splicing screw is a hollow screw with a male end and a female end. This facilitates the splicing of screws with each other and with components such as fixing bolts. The splicing screws come in various lengths, such as 1cm, 2cm, and 3cm.

[0012] Furthermore, in the aforementioned structural joint deformation monitoring device, the micrometer measuring rod has a fixing nut and a measuring rod clamping sleeve at both ends; the fixing nut has a closing function, enabling it to lock the measuring rod or support rod firmly in the base bolt or splicing screw. The measuring rod clamping sleeve is a protective device for the micrometer measuring rod, protecting it from external interference and preventing it from swaying left and right without affecting measurement accuracy, while ensuring its free extension and retraction.

[0013] Furthermore, in the aforementioned structural joint deformation monitoring device, both the left and right structures are equipped with base nuts. The base nuts have two ends, with the bottom end fixed to the center of the device's base plate and the other end equipped with a male screw. The male screw on the left structure is connected to the fixing nut, and the male screw on the right structure is connected to the bottom of the splicing screw rod.

[0014] Furthermore, in the aforementioned structural joint deformation monitoring device, a horizontal micrometer support rod is provided at the bottom of the horizontal micrometer instrument panel, and a fixing nut is provided at the bottom of the horizontal micrometer support rod; the fixing nut connects to the top of the splicing screw on the right side of the structure, and can be fixed by the fixing nut after the height is adjusted. Preferably, the horizontal micrometer support rod is a solid steel rod.

[0015] Furthermore, in the aforementioned structural joint deformation monitoring device, the left structure is connected to the splicing screw via a base nut, then to a fixing nut, and finally to the micrometer measuring rod of the right structure.

[0016] Furthermore, in the aforementioned structural joint deformation monitoring device, both the vertical and horizontal micrometer instrument panels are equipped with a micrometer digital display screen and a micrometer control button.

[0017] Preferably, the digital display screen of the micrometer is an LCD screen installed on the micrometer instrument panel, which can display the deformation, temperature and humidity measured by the internal sensors of the micrometer, and is usually in an automatic off state.

[0018] Preferably, the micrometer control button is a control button installed on the micrometer instrument panel, which has functions such as manually waking up the display screen, manual measurement, and viewing historical measurement data.

[0019] Furthermore, in the aforementioned structural joint deformation monitoring device, a measuring rod protection tube is provided on the free end of the measuring rod that penetrates the vertical micrometer instrument panel and the horizontal micrometer instrument panel. The measuring rod protection tube is a hollow tube with an inner diameter slightly larger than the outer diameter of the measuring rod.

[0020] Furthermore, the method of using the above-mentioned structural joint deformation monitoring device includes the following steps:

[0021] Step 1: Based on the location of the joint in the structure to be tested, clean the corresponding surfaces of the left and right structures, and position the installation position of the device base plate on both structures to ensure that the axes of the two base plates coincide in the direction perpendicular to the joint.

[0022] Step 2: Measure the initial misalignment and opening of the left and right structures and record the initial values. At the same time, based on the measured initial values ​​and the center distance between the two device base plates, determine the number and size of the splicing bolts required in the horizontal and vertical directions.

[0023] Step 3: Use anchoring adhesive or fixing bolts to install the two device base plates to the pre-positioned installation positions on the structure.

[0024] Step 4: Based on the initial misalignment, determine the splicing screws that need to be installed on the right base plate and install them on the base nuts on the right side. Put the fixing nut on the right side transverse micrometer support rod and insert it into the right splicing screw. Then tighten the fixing nut to initially fix the transverse micrometer support rod on the splicing screw.

[0025] Step 5: Put the micrometer measuring rod of the left vertical micrometer into the base nut on the left base plate, roughly adjust the height, and then tighten the left fixing nut to fix it in place.

[0026] Step 6: Install the determined splicing screw on the base nut on the right side of the vertical micrometer instrument panel on the left side. Put the micrometer measuring rod of the horizontal micrometer instrument panel on the right side into the fixing nut, roughly adjust the distance, and then tighten the upper fixing nut to fix it initially.

[0027] Step 7: Fine-tune the measuring device by fixing the nuts in three positions to prevent skewing and bending from affecting the measurement accuracy;

[0028] Step 8: Turn on the two micrometers using the micrometer control button, set the initial values ​​of structural joint misalignment and opening on the platform using the built-in communication module, and set the monitoring frequency of the device to achieve automated monitoring.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] (1) The measuring device uses a digital micrometer distance measuring instrument and has a built-in communication module. It can record and store the changes in transverse misalignment and longitudinal opening displacement of structural joint deformation in real time, and automatically upload them to the intelligent platform. This enables real-time viewing and risk analysis of structural joint deformation, which is more conducive to ensuring the safety of the structure.

[0031] (2) The device can simultaneously measure the opening and misalignment of the structural joint. The digital display screen and operation buttons can also realize real-time deformation observation on site. Overall, the operation is relatively simple and the applicability is wide.

[0032] (3) The device is not only highly accurate and small in size, but also low in cost and reusable, and has high engineering application value. Attached Figure Description
