Description

A modular adjustable steel structure monitoring support device Technical Field

[0001] This utility model relates to the field of building construction equipment technology, specifically a modular adjustable steel structure monitoring support device. Background Technology

[0002] To reduce the use of bamboo and wood, steel structure supports are now widely used. Steel structure supports are supports made of steel. Although steel structure supports have high tensile strength and compressive strength, good toughness, high support capacity, high support strength, and can be used multiple times, they are an indispensable tool in the construction process.

[0003] For example, Chinese Patent No. CN220179306U discloses a steel structure engineering support device, which relates to the field of building construction equipment technology. It includes a base, an adjusting rod, and a support plate. The adjusting rod is fixedly connected to the top of the base, and the support plate is connected between the adjusting rods. The adjusting rod includes a rod body, a first connecting hole, a second connecting hole, and a sliding groove. The sliding groove is provided inside the rod body, and the first connecting hole and the second connecting hole are provided on both sides of the sliding groove. The support plate has sliders on both sides, and a limiting hole is provided in the middle of the slider. The sliders are slidably connected to the sliding groove. The first connecting hole, the second connecting hole, and the limiting hole are connected by screws and nuts. This utility model can realize the adjustment of the support height, thereby improving the applicability of the support. At the same time, the bottom of the engineering support is equipped with casters, which facilitates the movement of the engineering support.

[0004] However, the aforementioned steel structure support devices cannot monitor stress changes in key parts of the steel structure in real time during the support process, such as under loads and wind loads, in order to assess the load-bearing capacity and safety of the steel structure. Summary of the Invention

[0005] The purpose of this utility model is to provide a modular adjustable steel structure monitoring support device to solve the problem mentioned in the background art that it is impossible to monitor the stress changes of key parts of the steel structure under load, wind load and other effects in real time during the process of supporting the steel structure.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A modular adjustable steel structure monitoring support device includes: four sets of pillars and connecting plates. The outer surfaces of the four sets of pillars are rotatably connected to both ends of a first connecting arm, and the outer surfaces of the four sets of pillars are slidably mounted with a slide cylinder. The outer surfaces of the slide cylinders are rotatably mounted with a second connecting arm at both ends. The other ends of the first and second connecting arms of each set of pillars are rotatably mounted on one end of the connecting plate, thereby forming a square aperture between the four sets of pillars. The four sets of pillars are slidably mounted on the outer surface of a height adjustment mechanism, which is located at the center of the four sets of pillars.

[0008] Preferably, by sliding the slide cylinder along the support column, the second connecting arm can be driven to rotate, and the first connecting arm can be linked to achieve the four sets of support columns to expand or contract synchronously in the radial direction at equal intervals with the height adjustment mechanism as the center, thereby changing the size of the square diameter enclosed by the four sets of support columns, completing the flexible adjustment of the lateral dimensions of the support device, so that the four sets of support columns can support the steel structure in different parts.

[0009] Preferably, the upper and lower ends of the sliding sleeve on the outer surface of the support are threaded with wing bolts, and the threaded part of the wing bolt can be screwed into the limiting groove, which is opened at one end of the support.

[0010] Preferably, rubber blocks are fixedly installed on the upper surfaces of the four sets of support columns, and strain gauges are embedded in the rubber blocks, with the surface height of the strain gauges being flush with the rubber blocks.

[0011] Preferably, the connecting plate is provided with multiple mounting holes for detachable installation of the monitoring device, which is connected to the strain gauge via a wireless signal transmitting module.

[0012] Preferably, when the support column supports the steel structure, the rubber block at the top, due to its good plasticity, deforms under pressure, thereby causing the strain gauge to fit tightly against the lower surface of the steel structure. At the same time, the pressure is evenly transmitted to the surface of the strain gauge, so that the strain gauge can fully contact and fit tightly against the lower surface of the steel structure, thus achieving stable support for the steel structure and ensuring that the strain gauge accurately obtains the stress change data of the steel structure.

[0013] Preferably, the height adjustment mechanism includes four sets of first extension columns, each of which is slidably installed on the lower inner surface of the support column, and a connecting pipe is fixedly installed on the lower surface of each of the four sets of first extension columns. A second extension column is slidably installed inside each of the four sets of connecting pipes, and an installation plate is fixedly installed between the other ends of the four sets of second extension columns.

[0014] Preferably, a jack is fixedly mounted on the upper surface of the mounting plate, a third extension column is fixedly mounted on the outer surface of the piston rod of the jack, and the third extension column is slidably mounted inside the slide tube, which is fixedly mounted on the outer surface of the support column.

[0015] Preferably, the lower surface of the mounting plate is flush with the lower surfaces of the four sets of connecting pipes, so that they can support it together.

[0016] Preferably, this allows the four sets of support columns to be lifted synchronously by jacks via sliding pipes.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. Through the design of the support columns, first connecting arm, second connecting arm, connecting plate, rubber block, strain gauge, and height adjustment mechanism, during use, the operator can extend or push the support columns according to the support requirements of the steel structure. The four sets of support columns can slide along the support columns via sliding cylinders on their outer surfaces, which can drive the second connecting arm to rotate, simultaneously linking with the first connecting arm. This allows the four sets of support columns to expand or contract synchronously and radially at equal intervals around the height adjustment mechanism, thereby changing the size of the square formed by the four sets of support columns. This achieves flexible adjustment of the lateral dimensions between the support columns, enabling the four sets of support columns to support different parts of the steel structure. After adjusting the expanded or contracted support columns, the four sets of support columns can be placed in the corresponding support positions, and then the height adjustment mechanism can be activated. The height adjustment mechanism will push the four sets of support columns to rise synchronously, so that the top touches the lower surface of the steel structure. When the support is provided from below, the strain gauges embedded in the rubber blocks at the top of the support columns will also fit tightly against the lower surface of the steel structure, thus ensuring the steel structure... The minute deformation caused by stress is synchronously transmitted to the strain gauge, causing its internal resistance to change precisely with the deformation due to the piezoresistive effect. This change in resistance is linearly related to the strain of the steel structure. After the strain gauge converts the physical deformation into an electrical signal change, it is encoded and modulated into radio electromagnetic waves by a wireless signal transmission module. These waves are then transmitted at a specific frequency and received by monitoring equipment installed on the connection board. Upon receiving the signal, the monitoring equipment first amplifies it using a high-precision signal amplifier, then uses a filtering circuit to remove noise caused by environmental electromagnetic interference to ensure signal purity. Subsequently, the analog electrical signal is converted into a digital signal by an analog-to-digital converter module. Based on the calibration parameters of the strain gauge and material mechanics formulas, the system calculates key data such as the real-time stress value and strain amplitude of the steel structure. This real-time, high-precision monitoring capability can capture subtle changes in the steel structure under various working conditions, providing reliable data support for the safety assessment and maintenance of the steel structure, and effectively preventing structural damage or safety accidents caused by abnormal stress.

[0019] 2. Through the design of the mounting plate, second extension column, connecting pipe, first extension column, jack, and third extension column, after the support columns are positioned, workers can press the jack installed on the upper surface of the mounting plate to start the piston rod's extension and retraction. The third extension column, which is fixedly connected to the outer surface of the piston rod, is slidably installed in the sliding pipe fixed to the outer surface of the support column. This allows the piston rod to drive the third extension column to synchronously push the four sets of support columns to rise or fall within the sliding pipe. During the lifting and lowering process, the four sets of support columns will slide on the outer surface of the first extension column respectively. The second extension columns installed at the four ends of the mounting plate allow the four sets of support columns to drive the connecting pipe to move laterally on the outer surface of the second extension column during the expansion process, thus playing a guiding role. The height adjustment function can flexibly adapt to steel structures of various heights in different steel structure engineering scenarios, such as bridges, high-rise buildings, and large factories. Whether it is monitoring the bottom steel beams or supporting and monitoring the nodes of high-rise steel structures, the height can be adjusted to meet actual needs, greatly expanding the application range of the support and improving its versatility.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please refer to Figures 1-3. This embodiment provides the following technical solution:

[0026] As shown in Figure 1, a modular adjustable steel structure monitoring support device includes: four sets of support columns 1 and connecting plates 104. First connecting arms 101 are rotatably connected to both ends of the outer surfaces of the four sets of support columns 1, and sliding cylinders 103 are slidably installed on the outer surfaces of the four sets of support columns 1. Second connecting arms 102 are rotatably installed on both ends of the outer surfaces of the sliding cylinders 103. The other ends of the first connecting arms 101 and second connecting arms 102 of each set of support columns 1 are rotatably installed on one end of the connecting plate 104, thereby forming a square aperture between the four sets of support columns 1. Each set of support columns 1 is mounted on the outer surface of the height adjustment mechanism 2, which is located at the center of the four sets of support columns 1. By sliding the slide cylinder 103 along the support column 1, the second connecting arm 102 can be rotated, simultaneously coordinating with the first connecting arm 101. This allows the four sets of support columns 1 to expand or contract synchronously and radially at equal intervals around the height adjustment mechanism 2, thereby changing the size of the square formed by the four sets of support columns 1. This enables flexible adjustment of the lateral dimensions of the support device, allowing the four sets of support columns 1 to accommodate different parts of the steel structure. The structure provides support. The upper and lower ends of the sliding cylinder 103, which is fitted onto the outer surface of the support column 1, are threaded with wing bolts 109. The threaded portion of the wing bolts 109 can be screwed into the limiting groove 107, which is located at one end of the support column 1. Rubber blocks 105 are fixedly installed on the upper surface of all four sets of support columns 1. Strain gauges 106 are embedded within the rubber blocks 105, and the surface height of the strain gauges 106 is flush with the rubber blocks 105. Multiple mounting holes are provided on the connecting plate 104 for detachable installation of monitoring equipment. The monitoring equipment is connected to the strain gauge 106 via a wireless signal transmission module. When the support column 1 supports the steel structure, the rubber block 105 at the top deforms under pressure due to its good plasticity. This causes the strain gauge 106 to fit tightly against the lower surface of the steel structure, and the pressure is evenly transmitted to the surface of the strain gauge 106. This allows the strain gauge 106 to fully contact and adhere to the lower surface of the steel structure, thus achieving stable support for the steel structure and ensuring that the strain gauge 106 accurately acquires the stress change data of the steel structure.

[0027] Through the design of the support column 1, the first connecting arm 101, the second connecting arm 102, the connecting plate 104, the rubber block 105, the strain gauge 106, and the height adjustment mechanism 2, during use, the operator can extend or push the support column 1 according to the support requirements of the steel structure. The four sets of support columns 1 can slide along the support column 1 via the sliding cylinder 103 on the outer surface, which can drive the second connecting arm 102 to rotate, and at the same time link the first connecting arm 101. This allows the four sets of support columns 1 to expand or contract synchronously in a radial direction at equal intervals around the height adjustment mechanism 2, thereby changing the square formed by the four sets of support columns 1. The size of the aperture allows for flexible adjustment of the lateral dimensions between the four sets of supports 1, enabling them to support different parts of the steel structure. After adjusting the expanded or retracted supports 1, the four sets of supports 1 can be placed in their respective support positions, and then the height adjustment mechanism 2 can be activated. The height adjustment mechanism 2 will push the four sets of supports 1 to rise synchronously until their tops touch the lower surface of the steel structure. When the supports are providing support from below the steel structure, the strain gauges 106 embedded in the rubber blocks 105 at the top of the supports 1 will fit tightly against the steel structure. On the lower surface of the structure, the minute deformations caused by the stress on the steel structure are synchronously transmitted to the strain gauge 106. Based on the piezoresistive effect of the strain gauge 106, its internal resistance changes precisely with the deformation. This change in resistance is linearly related to the strain magnitude of the steel structure. After the strain gauge 106 converts the physical deformation into an electrical signal change, it encodes and modulates the electrical signal into radio electromagnetic waves via a wireless signal transmission module. These waves are transmitted at a specific frequency and received by the monitoring equipment installed on the connection plate 104. Upon receiving the signal, the monitoring equipment first amplifies it using a high-precision signal amplifier, then uses a filtering circuit to remove noise generated by environmental electromagnetic interference, ensuring signal purity. Subsequently, the analog electrical signal is converted into a digital signal via an analog-to-digital converter module. Based on the calibration parameters of the strain gauge 106 and material mechanics formulas, the real-time stress value, strain amplitude, and other key data of the steel structure are calculated. This real-time, high-precision monitoring capability can capture subtle changes in the steel structure under various working conditions, providing reliable data support for the safety assessment and maintenance of the steel structure, and effectively preventing structural damage or safety accidents caused by abnormal stress.

[0028] As shown in Figures 2 and 3, the height adjustment mechanism 2 includes four sets of first extension columns 204. The four sets of first extension columns 204 are slidably installed on the lower inner surface of the support column 1, and a connecting pipe 203 is fixedly installed on the lower surface of each of the four sets of first extension columns 204. A second extension column 202 is slidably installed inside each of the four sets of connecting pipes 203, and an installation plate 201 is fixedly installed between the other ends of the four sets of second extension columns 202. A jack 205 is fixedly installed on the upper surface of the installation plate 201, and a third extension column 206 is fixedly installed on the outer surface of the piston rod of the jack 205. The third extension column 206 is slidably installed inside the slide tube 108, which is fixedly installed on the outer surface of the support column 1. The lower surface of the installation plate 201 is flush with the lower surface of the four sets of connecting pipes 203, so that they can support each other together, thereby enabling the four sets of support columns 1 to be synchronously lifted by the jack 205 through the slide tube 108.

[0029] Through the design of the mounting plate 201, the second extension column 202, the connecting pipe 203, the first extension column 204, the jack 205, and the third extension column 206, after the support column 1 is positioned, the worker can press the jack 205 installed on the upper surface of the mounting plate 201 to start the piston rod to extend and retract. The third extension column 206, fixedly connected to the outer surface of the piston rod, is slidably installed within the slide tube 108 fixed to the outer surface of the support column 1. This allows the piston rod to drive the third extension column 206 to synchronously push the four sets of support columns 1 to rise or fall within the slide tube 108. Furthermore, during the raising and lowering of the support column 1, the four sets of... The support column 1 will slide on the outer surface of the first extension column 204 respectively, while the second extension column 202 installed at the four ends of the mounting plate 201 can drive the connecting pipe 203 to move laterally on the outer surface of the second extension column 202 during the expansion process, thereby playing a guiding role. Moreover, the height adjustment function can flexibly adapt to steel structures of various heights in different steel structure engineering scenarios, such as bridges, high-rise buildings, and large factories. Whether it is monitoring the bottom steel beams or supporting and monitoring the nodes of high-rise steel structures, the actual needs can be met by adjusting the height, which greatly expands the application range of the bracket and improves its versatility.

[0030] Among them, the monitoring equipment can be the TSK-64 strain gauge, which integrates a Lora gateway (433MHz band), has a transmission distance of 300m, and supports remote data monitoring and cloud storage. The strain gauge 106 can be the AKEMONDTSK-1A-120-3A-11L50W07MS triaxial foil strain gauge, which has high sensitivity and is suitable for dynamic and static stress monitoring.

[0031] Based on the above technical solution, the working steps of this solution are summarized as follows: During use, workers can extend or push the support column 1 according to the required support for the steel structure. The four sets of support columns 1 can slide along the support column 1 via the sliding cylinder 103 on the outer surface, driving the second connecting arm 102 to rotate. Simultaneously, this drives the first connecting arm 101, enabling the four sets of support columns 1 to expand or contract synchronously radially and equidistantly around the mounting plate 201. During this expansion or contraction, the connecting pipe 203, which is slidably installed on the lower surface, will also slide on the outer surface of the second extension column 202, which is fixedly installed at the four ends of the mounting plate 201, thereby changing the four... The size of the square formed by the four sets of support columns 1 allows for flexible adjustment of the lateral dimensions between the support columns 1, enabling the four sets of support columns 1 to support different parts of the steel structure. After adjusting the extended or retracted support columns 1, the four sets of support columns 1 can be placed in the corresponding support positions, allowing workers to press the jack 205 installed on the upper surface of the mounting plate 201 to initiate the extension and retraction of the piston rod. The third extension column 206, which is fixedly connected to the outer surface of the piston rod, is slidably installed in the slide tube 108 fixed to the outer surface of the support column 1, thus allowing the piston rod to drive the third extension column 206 to slide. The pipe 108 synchronously pushes four sets of support columns 1 to lift or lower them. During the lifting and lowering of the support columns 1, the four sets of support columns 1 will slide on the outer surface of the first extension column 204 respectively. The lifted support column 1 will cause the strain gauge 106 embedded in the top rubber block 105 to be tightly attached to the lower surface of the steel structure. In this way, the small deformation of the steel structure under stress will be synchronously transmitted to the strain gauge 106. According to the piezoresistive effect of the strain gauge 106, its internal resistance value will change precisely with the deformation. The amount of resistance change is linearly related to the strain of the steel structure. The strain gauge 106 will transfer the material... After the physical deformation is converted into an electrical signal change, the electrical signal is encoded and modulated into radio electromagnetic waves by the wireless signal transmission module. These waves are then transmitted to the outside world at a specific frequency and received by the monitoring equipment installed on the connection plate 104. After receiving the signal, the monitoring equipment first amplifies it through a high-precision signal amplifier, and then uses a filter circuit to remove noise generated by environmental electromagnetic interference to ensure signal purity. Subsequently, the analog electrical signal is converted into a digital signal through an analog-to-digital converter module. Based on the calibration parameters of the strain gauge 106 and the material mechanics formulas, the real-time stress value, strain amplitude, and other key data of the steel structure are calculated for staff to observe.

[0032] In summary, this device enables real-time monitoring of stress changes while supporting the steel structure. This real-time, high-precision monitoring capability can capture subtle changes in the steel structure under various working conditions, providing reliable data support for the safety assessment and maintenance of the steel structure, and effectively preventing structural damage or safety accidents caused by abnormal stress.
