Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel support structure processing technology, and in particular to a steel support mechanism. Background Technology
[0002] Steel support structures are mainly used for automated monitoring of formwork support frames in buildings and bridges. Ensuring the safety and stability of the construction process is always the core focus, and the selection and application of support frames play a crucial role. In the early days, wooden and bamboo supports were commonly used in conjunction with wooden formwork projects. However, these traditional support materials have many limitations. For example, wooden supports are prone to deformation due to moisture and have limited strength, while bamboo supports have poor durability. In the construction of large, high-rise, and complex structures, they are unable to meet the ever-increasing safety and load-bearing requirements.
[0003] With the advancement of the times, socket-type steel pipe supports have begun to be widely developed and applied. The structure of this support is similar to that of fastener-type steel pipe supports. However, in the current steel support mechanism, the sensor is usually set on the sensor plate on the top side of the steel pipe support. The sensor has low detection accuracy and is exposed to the outside, which leads to a reduced service life. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a steel support mechanism that installs some or all of the sensors inside the steel pipe sleeve to improve detection accuracy and detection life.
[0005] The technical problem solved by this utility model is achieved through the following technical solution:
[0006] A steel support mechanism includes a steel pipe top support, a steel pipe, and a sensor support plate. The steel pipe is used to connect two sets of steel joints. The steel pipe top support and the sensor support plate are both located on the steel pipe. A steel pipe sleeve is provided at one end of the steel pipe. An inclination sensor and an axial force sensor are provided on the axis inside the steel pipe sleeve. A slidable movable pad is provided inside the steel pipe sleeve. The movable pad forms a cavity in the steel pipe sleeve. The inclination sensor and the axial force sensor are both located in the cavity. The movable pad can slide inside the cavity to compress the space of the cavity.
[0007] Furthermore, the chamber is provided with a fixed partition, which divides the chamber into a first mounting cavity and a second mounting cavity along the axial direction. The first mounting cavity is used to install an tilt sensor, and the inner wall of the second mounting cavity is provided with a first spring pin. The movable pad is located on the first spring pin, and the movable pad can slide in the second mounting cavity to compress the space of the second mounting cavity. The second mounting cavity is used to install an axial force sensor.
[0008] Furthermore, both the first mounting cavity and the second mounting cavity have a first opening through the steel pipe sleeve on their side walls, and the first opening is arranged along the axial direction of the steel pipe sleeve. The first opening of the first mounting cavity is filled with expanding foam for fixing the tilt sensor.
[0009] Furthermore, the inner wall of the cavity is provided with a second spring pin, the movable pad is located on the second spring pin, the axial force sensor is sleeved outside the tilt sensor and located inside the cavity, and the side walls of the cavity are provided with a second opening penetrating the steel pipe sleeve, and the second opening is arranged along the axial direction of the steel pipe sleeve.
[0010] Furthermore, the sensor plate is equipped with a horizontal displacement sensor and a settlement displacement sensor.
[0011] Furthermore, the inner diameter of the steel pipe sleeve is larger than the inner diameter of the steel pipe.
[0012] The advantages and positive effects of this utility model are: by setting a steel pipe sleeve, both the tilt sensor and the axial force sensor are installed inside the steel pipe sleeve, so that the tilt sensor is located on the axis of the steel pipe sleeve, avoiding the influence of external factors on the accuracy of the detection data and improving its service life. Furthermore, by setting the tilt sensor downward, the tilt angle data can be designed accordingly to realize the actual derivation of the tilt angle at the top support of the steel pipe.

[0019] The embodiments of this utility model will be further described in detail below with reference to the accompanying drawings:
[0020] In current steel support mechanisms, sensors are typically mounted on a sensor support plate 3 on one side of the steel pipe top support 1. This results in low sensor accuracy and reduced lifespan due to external exposure. Therefore, this invention designs a steel support mechanism including a steel pipe top support 1, a steel pipe 2, and a sensor support plate 3. The sensor support plate 3 is equipped with a horizontal displacement sensor 15 and a settlement displacement sensor 16. The steel pipe 2 supports the concrete formwork, and the steel pipe 2 connects two sets of steel joints (specifically, a threaded steel bar vertically inserted into the steel pipe 22 from the bottom of the steel rail top support, and another threaded steel bar from the ground or other support platform inserted into the steel pipe 22 from the other end, with the ends of the two threaded steel bars abutting against each other). The steel pipe support 1 and the sensor support plate 3 are both located on the steel pipe 2. One end of the steel pipe 2 is provided with a steel pipe sleeve. The inner diameter of the steel pipe sleeve is larger than the inner diameter of the steel pipe 2. An inclination sensor 5 and an axial force sensor 6 are provided on the axis inside the steel pipe sleeve. A sliding movable pad 11 is provided inside the steel pipe sleeve. The movable pad 11 constructs a cavity in the steel pipe sleeve. The inclination sensor 5 and the axial force sensor 6 are both located in the cavity. The inclination sensor 5 is located on the axis of the steel pipe sleeve to avoid external factors affecting the accuracy of the detection data and to improve its service life. The movable pad 11 can slide in the cavity to compress the space of the cavity. The axial force sensor 6 is located at the abutment of two threaded steel bars and is used to monitor the axial force.
[0021] Example 1
[0022] like Figure 1As shown, the diameter of the steel pipe sleeve is larger than the diameter of the steel pipe 2. A fixed partition 7 is provided within the chamber, dividing the chamber along the axial direction (the length direction of the steel pipe sleeve) into a first mounting chamber 8 and a second mounting chamber 9. The first mounting chamber 8 is used to install the tilt sensor 5, and can also accommodate a settlement sensor and a horizontal displacement sensor 15, etc. The inner wall of the second mounting chamber 9 is machined with symmetrically distributed mounting holes for first spring pins 10. The pins are made of high-strength spring steel, capable of withstanding axial pressure and providing elastic reset. A movable pad 11 is located on the first spring pin 10 and is movable... The pad 11 can slide within the second mounting cavity 9 to compress the space of the second mounting cavity 9. The second mounting cavity 9 is used to install the axial force sensor 6. When the steel support structure needs to be installed, the threaded steel bar on the ground or support platform is inserted into the sleeve of the steel pipe 2. The end of the threaded steel bar pushes the movable pad 11 upward. The movable pad 11 slides upward to push the axial force sensor 6 located in the second mounting cavity 9. When it is pushed to a certain position, the top surface of the axial force sensor 6 presses against the bottom surface of the fixed partition 7, and the bottom surface of the axial force sensor 6 presses against the end face of the threaded steel bar for subsequent axial force monitoring.
[0023] To facilitate the disassembly and assembly of the tilt sensor 5 and the axial force sensor 6, a first opening 12 penetrating the steel pipe sleeve is provided on the side wall of both the first mounting cavity 8 and the second mounting cavity 9. The first opening 12 is arranged along the axial direction of the steel pipe sleeve. The first opening 12 of the first mounting cavity 8 is filled with expanding foam for fixing the tilt sensor 5. The expanding foam can be quickly injected and removed, supporting the non-destructive replacement of the tilt sensor 5. The movable pad 11 adopts a modular quick-release design. The axial force sensor 6 can be removed by simply removing the spring pin, reducing the maintenance time to 1 / 3 of the traditional structure.
[0024] Example 2
[0025] like Figure 2As shown, based on Embodiment 1, Embodiment 2 further optimizes the internal spatial layout of the sleeve. The diameter of the steel pipe sleeve is larger than the diameter of the steel pipe 2. A second spring pin 13 is provided on the inner wall of the cavity. Its material and installation method are the same as the first spring pin 10. They are symmetrically distributed on both sides of the sleeve axis. The movable pad 11 is located on the second spring pin 13. The axial force sensor 6 is sleeved outside the tilt sensor 5 and is located inside the cavity. In this utility model, the outer body of the axial force sensor 6 is in the shape of a cylindrical ring. The tilt sensor 5 can be cylindrical with the same diameter as the inner diameter of the axial force sensor 6. This nested design saves a lot of space and ensures that the data acquisition position of the tilt sensor and the axial force sensor 6 is highly coincident, reducing the error caused by the offset of the measurement point. It is located inside the cavity. Similarly, during installation, the threaded steel is inserted from the bottom of the steel pipe sleeve, and its end... The movable pad 11 is lifted and slides upward under the thrust, compressing the chamber space and simultaneously pushing the movable pad 11 to move within the chamber. When the threaded steel is lifted to the preset position, the bottom surface of the axial force sensor 6 is in close contact with the end face of the threaded steel, while the top surface presses against the end of the threaded steel at the bottom of the steel pipe top, forming a "double-end rigid fixing" structure. The movable pad 11 does not contact the tilt sensor 5, and the threaded steel at the bottom of the steel pipe top does not contact the tilt sensor 5. The side walls of the chamber are provided with a second opening 14 that penetrates the steel pipe sleeve, and the second opening 14 is set along the axial direction of the steel pipe sleeve. The second opening 14 has both heat dissipation and disassembly functions. The movable pad 11 slides and compresses the chamber space, and excess gas or liquid can be quickly discharged through the second opening 14 to avoid the pressure change in the chamber interfering with the sensor reading.
[0026] It should be emphasized that the embodiments described in this utility model are illustrative rather than limiting. Therefore, this utility model is not limited to the embodiments described in the specific implementation. Any other implementation methods derived by those skilled in the art based on the technical solutions of this utility model are also within the scope of protection of this utility model.
