Description

Technical Field

[0001] The present application relates to the technical field of unloading construction monitoring, and in particular to a hardware system for real-time monitoring of building structure performance and a monitoring method thereof. Background Art

[0002] With the rapid development of my country's economy and society, the country has attached increasing importance to public infrastructure, especially the increasing number of large-scale public cultural and sports buildings. Among them, public projects such as stadiums, airport terminals, passenger stations, and convention and exhibition centers have emerged.

[0003] A common characteristic of these projects is that the roof structure is often designed with slopes or irregular shapes due to its high height and large span. Due to construction design, environmental, and application considerations, many projects may involve partial structural modifications during or after completion. These modifications can include changes to walls or building plans. Whenever these modifications occur, a highly secure construction plan is required. This is especially true when modifying supporting columns, which can significantly impact the building structure. Improving the safety of these modifications during these renovations has become a pressing technical challenge for those skilled in the art. Summary of the Invention

[0023] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0024] In this document, the term "and / or" simply describes a relationship between related objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document, unless otherwise specified, generally indicates an "or" relationship between the related objects.

[0025] The embodiments of the present application are described in further detail below with reference to the accompanying drawings.

[0026] There are several types of large-span structural reinforcement and renovation projects. The renovation project described in this application example is a cement column reinforcement and renovation project. After the overall structure of a frame building has been completed, due to local changes in the building plan, some supporting columns need to be reinforced. The specific reinforcement method is to increase the cross-sectional area of ​​the columns.

[0027] Reference Figure 1 Generally, before reinforcement construction, the inspection department will detect the stress at the relevant positions, and then the design department will design the reinforcement data of the reinforcement structure based on the stress; during the construction process, the construction department will carry out reinforcement construction at the positions to be reinforced based on the reinforcement data; after the construction is completed, the inspection department will inspect the construction quality. There are generally two ways of reinforcement: one is to build another group or multiple groups of supporting steel structures near the columns. Under normal circumstances, this type of supporting steel structure is difficult to meet the support strength requirements of the original columns; the other is to drill holes in the columns, erect a steel skeleton around the columns, and connect the steel skeleton to the internal steel structure of the columns through the punching positions, and finally become one with the steel skeleton by pouring concrete. The reinforcement construction described in this application is a construction method of reinforcing the columns by drilling holes.

[0028] During building reinforcement construction, different column reinforcement designs vary, such as varying thicknesses of the reinforcement structure. The inventors discovered that for thin reinforcement structures, the inevitable presence of air bubbles or uneven cement during the cement pouring process can cause the structural strength of the reinforcement structure to decrease after a period of use. If a supporting structure is required to be rebuilt on top of the reinforcement structure, the support strength of the supporting structure will be unreliable.

[0029] Reference Figure 2As shown, based on the problems discovered by the inventors, an embodiment of the present application provides a hardware system for real-time monitoring of building structure performance, wherein the hardware system includes a removable support structure, a vertical pressure detection device, a horizontal displacement detection device, a data acquisition device, a central control device and a temperature control device.

[0030] The removable support structure is used to support the building structure at pre-set support points during the reinforcement construction process. For example, during the column processing, the frame beams associated with the column are supported to ensure the overall structural strength of the building structure during the reinforcement construction process.

[0031] The removable support structure described in this application is a steel truss. Before reinforcing the columns, the columns must first be preliminarily reinforced to ensure the strength of the building structure during the steel truss construction process. After the steel truss construction is completed, the columns are then punched and reinforced.

[0032] It should be noted that before the construction of the steel truss, each column to be reinforced needs to be preliminarily processed. The method of preliminarily processing can be to erect an I-beam structure around the column, or it can be other reinforcement methods, which are not limited in this application. During the construction of the steel truss, the steel truss associated with each column is installed with the vertical pressure detection device and the horizontal displacement detection device. The vertical pressure detection device and the horizontal displacement detection device are pressure sensors and horizontal displacement sensors. The pressure sensor and the horizontal displacement sensor are used to detect the vertical pressure on the unloadable support structure and the horizontal displacement of the support position of the unloadable support structure, respectively. The method of arranging pressure sensors and horizontal displacement sensors in the steel truss structure is a conventional method in this field and will not be elaborated here.

[0033] The data acquisition device is connected to the pressure sensor and horizontal displacement sensor via a 4G communication module and collects the vertical pressure and horizontal displacement output by the pressure sensor and horizontal displacement sensor via the Modbus protocol. The data acquisition device also includes a built-in GPRS module and is connected to the central control unit via GPRS. The 4G communication module and GPRS connection ensure information transmission between the construction site and the central control unit, enabling information transmission within any area covered by mobile phone signals.

[0034] When multiple data acquisition devices are connected to the central control device, multiple GPRS modules can be mapped to the same serial port of the central control device, and each GPRS module can be set with a different communication address to facilitate distinguishing different GPRS modules from the communication address. Alternatively, each GPRS module can be mapped to a separate serial port, and each module can be set to actively send or passively send. This application does not impose a single limitation on the connection method between the data acquisition device and the central control device. The above is the preferred communication method between the data acquisition device and the central control device.

[0035] The temperature control device includes a soft water pipe and a heater, a refrigerator and a circulation pump connected to the soft water pipe. During operation, the circulation pump can drive the water to circulate in the soft water pipe. During the water circulation in the soft water pipe, the water can be heated or cooled by the heater or refrigerator.

[0036] During the reinforcement construction process, a temperature control device is arranged on a column whose thickness of the reinforcement structure is less than a preset thickness value. The temperature control device is used after the construction of the column reinforcement structure is completed, that is, after the reinforcement structure is initially solidified. When the cement of the reinforcement structure solidifies, the soft water pipe is wrapped around the outer surface of the frame structure, and the temperature of the reinforcement structure is adjusted by periodically replacing cold water and hot water circulation. The cold water and hot water circulation is a water circulation with different temperatures in the soft water pipe regulated by a refrigerator and a circulation pump. It should be noted that the refrigerator described in this application can use a separate water refrigerator or an ice storage tank, and the selection of the refrigerator is not limited in this application.

[0037] During the cold and hot water circulation process in the temperature control device, the data acquisition device collects data from the pressure sensor and displacement sensor in real time. Since cement is sensitive to thermal environments, the hot water circulation time should not be too long. The cold and hot water circulation provides an external environmental variable for the reinforced structure. When there is an air bubble interlayer inside the reinforced structure, the external environmental variable can cause the external deformation of the reinforced structure, making it easier for construction personnel to determine whether the reinforced structure is qualified. After the water in the temperature control device circulates for a preset time, if the reinforced structure is deformed, the reinforced structure needs to be reconstructed or subjected to secondary treatment.

[0038] The setting of the temperature control device enables the quality assessment of the reinforced structure between the initial solidification of the reinforced structure and the construction inspection, thereby reducing the impact of the construction progress caused by the construction inspection process.

[0039] Furthermore, the data acquisition device is also connected to the heater, refrigerator and circulation pump, and collects the heating temperature of the heater, the cooling temperature of the refrigerator and the working power of the circulation pump and uploads them to the central control device.

[0040] In a preferred example, the hardware system further includes an alarm device, which is wirelessly connected to the central control device. When the vertical pressure is greater than the preset vertical support force or horizontal deformation occurs, the central control device controls the alarm device to sound an alarm.

[0041] From the above content, it can be seen that by adjusting the temperature of the position to be reinforced at the preset construction node, the construction quality inspection of the building structure with thin reinforcement structure is realized, and the construction quality results are quickly provided for the building structure reinforcement construction.

[0042] In another embodiment, the present application further provides a method for real-time monitoring of building structure performance, the method comprising: detecting the vertical pressure and horizontal deformation output by the pressure sensor and displacement sensor, outputting an alarm signal when the vertical pressure exceeds a preset vertical support force or when horizontal deformation occurs, and controlling the location to be reinforced to maintain a preset temperature during the initial solidification of the reinforced structure.

[0043] Those skilled in the art should know that the functions described in the method of this embodiment can refer to the functional implementation of the response module in the hardware system, and the method is not described in detail in this embodiment.

For example, the device embodiments described above are merely illustrative. For example, the division of the modules, such as the data acquisition module and the central control module, can also be understood as only a logical function division. In actual implementation, there may be other division methods, such as multiple modules can be combined or integrated into another system, or some features can be ignored or not executed. Another point is that the mutual coupling or direct coupling or communication connection shown or discussed can be through some interfaces, indirect coupling or communication connection between devices and devices, which can be electrical, mechanical or other forms.

[0045] The modules described as separate components may or may not be physically separate.
