Description

Technical Field

[0001] The present invention relates to the field of supporting structures, in particular to a steel bar supporting structure with a detection function. Background Art

[0002] The Construction Engineering major is responsible for teaching and managing the construction engineering focus of the civil engineering major.

Construction engineering is a general term for all types of buildings and engineering facilities that provide the material and technological foundation for human life and production.

[0003] In current construction projects on the market, after the columns are cast, they are generally surrounded by steel bars on their surfaces to support and fix the columns until they are formed. However, the steel bar support devices currently on the market are partially fixed by tightening iron wires. This method wastes a lot of iron wires, resulting in a waste of resources. At the same time, it is also more troublesome to disassemble them. The existing support mechanism also lacks a device for detecting the support structure, and safety cannot be guaranteed after long-term use.

[0004] Steel support structures vibrate under dynamic loads such as wind and earthquakes, and these vibrations change with aging. This vibration is a crucial aspect of support structure analysis. The advent of computers and the application of the finite element method have made it possible to develop complex train bridge analysis models. Summary of the Invention

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1-6The present invention provides a steel bar support structure with a detection function, comprising a column, a fixing mechanism, a monitoring component and a cloud server, wherein a mounting seat 4 is installed on the top of the column 1, and a support seat 2 is installed on the top of the column 1, and a plurality of fixing holes are provided on the mounting seat 4 and the support seat 2, and a fixing anchor rod 3 is provided at the bottom of the mounting seat 4, the fixing mechanism comprises a fixing frame 13 and a fixing ring 8, one end of the fixing ring 8 is hinged to the fixing frame 13, and the fixing ring 8 is sleeved on the column 1, the monitoring component comprises a fiber grating strain sensor 9, a node conversion box 10 and a protective cover, the fiber grating strain sensor 9 is connected to the node conversion box 10 through an optical cable, the protective cover covers the optical cable and the fiber grating strain sensor 9, an A / D converter and a GPS module are provided in the node conversion box 10, the node conversion box 10 is connected to the cloud server through a remote communication network, and the node conversion box 10 is installed on the fixing frame 13.

[0028] The steel support structure with detection function is supported by the support of the column 1 and the support seat 2, and the support seat 2 is designed to be a trapezoidal structure so that the load is better transferred to the column 1, avoiding the stress deformation caused by uneven load distribution, which makes the column 1 or the support seat 2 easy to break. The mounting seat 4 and the support seat 2 can be assembled with the column 1 by welding or bolt connection. After the column 1 and the mounting seat 4 are assembled, the anchor rod is inserted into the fixed ground or wall to limit the column 1, and the stability of the column 1 is guaranteed by the mounting seat 4. The mounting seat 4 is installed on the ground or wall by bolts passing through the fixing holes, and the support seat 2 is connected to the supporting surface by bolts passing through the fixing holes. Two different columns 1 are spliced together by the fixing frame 13, and the splicing method is any one, as long as the column 1 and the fixing frame 13 are kept stably connected. Multiple columns 1 are connected together by the fixing frame 13 to ensure uniform load sharing, thereby improving the strength of the support structure and improving the support stability. The strain sensors 9 are respectively arranged at the joints of the column 1 and the support seat 2, the mounting seat 4 and the fixing frame 13, and at the center positions of the column 1 and the fixing frame 13. The above positions are all weak points of the support structure that are prone to breakage, so as to detect the supporting performance of the support structure composed of the column 1, the fixing frame 13, the support seat 2 and the mounting seat 4. During monitoring, the fiber optic Bragg grating strain sensor 9 monitors the steel support structure by reflecting light waves. The monitored reflected light wave wavelength signal is transmitted to the node conversion box 10 through the optical cable. The node conversion box 10 converts the light wave signal into an electrical signal that can be recognized by a computer by an A / D converter, and uploads the data to the cloud server through the remote communication network. The cloud server determines the location of the damage and identifies the degree of damage through the built-in information analysis and monitoring system, and evaluates the health status of the structure. When the evaluation result is abnormal, the cloud server issues an alarm message and accurately locates the damaged node of the steel support structure through the GPS module on the node conversion box 10.

[0029] In order to improve the convenience of installation of the fixing frame 13, in this embodiment, the fixing ring 8 includes two semicircular rings 11, one end of the semicircular ring 11 is hinged to the fixing frame 13, and the other end of the semicircular ring 11 is provided with a splicing edge 12, and the splicing edge 12 is provided with a splicing hole. The surface of the column 1 and the inner side of the semicircular ring 11 are provided with threads. During installation, the semicircular ring 11 is hinged to the fixing frame 13 to achieve flexible rotation and clamping of the column 1. At this time, the threads on the inner side of the semicircular ring 11 are consistent with the threads on the column 1, thereby preventing the semicircular ring 11 from sliding, and then the bolts are used to penetrate the splicing holes to achieve splicing of the two semicircular rings, thereby completing the installation of the fixing frame 13.

[0030] In order to improve the stability of the assembly of the fixing frame 13 and the column 1, in this embodiment, mounting grooves are provided at both ends of the fixing frame 13, and an annular slide groove is provided on the inner side of the mounting groove. The fixing ring 8 is embedded in the mounting groove and movably connected to the annular slide groove through a slide bar. The fixing ring 8 is set as a whole. During installation, the column 1 is inserted into the fixing rings 8 at both ends of the fixing frame 13 and connected through threads, and then the fixing rings 8 at both ends are rotated to the specified position of the column 1.

[0031] In order to improve the structural support of the fixing frame 13, in this embodiment, the fixing frame 13 includes an upper frame 5 and a lower frame 6, and a plurality of auxiliary rods 7 are provided between the upper frame 5 and the lower frame 6. The two ends of the auxiliary rods 7 are welded to the upper frame 5 and the lower frame 6 or connected by bolts.

[0032] In order to further improve the structural support of the fixing frame 13, in this embodiment, the auxiliary rods 7 are arranged in groups of two, and the two auxiliary rods 7 are cross-welded between the upper frame 5 and the lower frame 6. By arranging the auxiliary rods 7 in groups of two and cross-welding them, the vibration load absorbed at a certain point of the fixing frame 13 is dispersed to the two auxiliary rods 7, thereby improving the use effect of the auxiliary rods 7.

The first protective cover 14 and the second protective cover 15 are provided to protect the fiber Bragg grating strain sensor 9 and the optical cable to prevent the fiber Bragg grating strain sensor 9 and the optical cable from being damaged by impact. The working status of the fiber Bragg grating strain sensor 9 is detected by providing a sensor detector. When the fiber Bragg grating strain sensor 9 is working normally, the indicator light 20 is always on, and the sensor detector uploads the detected working status of the fiber Bragg grating strain sensor 9 to the A / D converter. The second protective covers 15 are spliced together by inserting the magnetic strip 21 of one of the second protective covers 15 into the magnetic groove for magnetic attraction, thereby ensuring the sealing of the splicing between the second protective covers 15.

[0034] In order to ensure the detection stability of the fiber Bragg grating strain sensor 9 and the stability of optical cable transmission data, in this embodiment, a braided shielding layer is provided in the first protective cover 14 and the second protective cover 15. The braided shielding layer is made of metal tin to reduce interference with electromagnetic signals.

[0035] In order to improve the stability of remote communication of the node conversion box 10, in this embodiment, a signal enhancement antenna 19 is provided on the node conversion box 10. The signal enhancement antenna 19 is hinged to the node conversion box 10 through a hinge seat 18. The hinge seat 18 facilitates the folding, storage or unfolding of the signal enhancement antenna 19 to improve the signal reception rate.
