Description

Technical Field

[0001] This invention belongs to the technical field of fully prefabricated steel-concrete composite floor slabs, specifically relating to a fully prefabricated steel-concrete composite floor slab system and its design calculation method. Background Technology

[0002] With the continuous advancement of the construction industry, the emergence of fully prefabricated modular buildings not only meets the comfort requirements of buildings, but is also a construction method that the country is strongly advocating for now and for some time to come. Compared with traditional French construction, prefabricated buildings are not affected by natural environments such as severe weather during the production process, and the construction period is more controllable.

[0003] However, while traditional building exterior walls have good sealing properties, prefabricated buildings are assembled on-site from prefabricated components. The joints between these components have always been a weak point in terms of waterproofing, leading to water seepage at these joints in actual engineering applications. This phenomenon has become a problem that urgently needs to be solved by professionals in this field. Summary of the Invention

[0004] The purpose of this invention is to provide a fully prefabricated steel-concrete composite floor system and design calculation method for existing material collection systems, in order to solve the problems mentioned in the background art.

[0005] To address the aforementioned technical problems, this invention provides the following technical solution: a fully prefabricated steel-concrete composite floor system and its design calculation method, comprising a scanning and storage terminal, an analysis and calculation terminal, and an execution and judgment terminal, characterized in that: the scanning and storage terminal and the analysis and calculation terminal are network-connected, the analysis and calculation terminal and the execution and judgment terminal are network-connected, the scanning and storage terminal is used by a drone to scan the assembled exterior wall, the analysis and calculation terminal is used by a computer to analyze the assembly joints of the exterior wall after assembly, and the execution and judgment terminal is used by the drone to determine the position of the assembly joints of the exterior wall based on the analyzed assembly joints.

[0006] The present invention further illustrates that the scanning and storage terminal includes a camera scanning module, a 3D imaging module, and a storage module. The camera scanning module and the 3D imaging module are network-connected, and the 3D imaging module and the storage module are electrically connected. The camera scanning module is used by a drone to scan the spliced ​​surface of the exterior wall. The camera scanning module includes an edge detection submodule, which is used by the drone to scan and detect details of the spliced ​​surface. The 3D imaging module is used to generate a 3D image of the scanned planar cross-sectional contour and details. The storage module is used to store the scanned 3D image.

[0007] The present invention further explains that the analysis and calculation terminal includes a cross-section simulation splicing module, a width measurement module, an angle measurement module, and a calculation and analysis module. The cross-section simulation splicing module and the width measurement module are electrically connected, the width measurement module and the angle measurement module are electrically connected, and the angle measurement module and the calculation and analysis module are electrically connected. The cross-section simulation splicing module is used to simulate splicing the external wall and extract information of the separated splicing joints. The width measurement module is used to measure the width of the splicing joints. The angle measurement module is used to measure the angle of the splicing joints. The calculation and analysis module is used to calculate and analyze the water seepage rate of the splicing joints.

[0008] The present invention further explains that the execution judgment end includes a location analysis module and an information transmission module, which are electrically connected. The location analysis module is used to analyze the location of the assembly joints of the exterior wall that need to be repaired, and the information transmission module is used to transmit the location information that needs to be repaired to the workers.

[0009] The present invention further explains that the design calculation method for the fully prefabricated steel-concrete composite floor slab mainly includes the following steps:

[0010] Step S1: The factory uses a crane to lift the exterior wall and starts the drone operation.

[0011] Step S2: The drone's scanning and storage device scans the exterior wall splicing surface being hoisted and the exterior wall splicing surface to be spliced ​​with it, and stores it on the computer.

[0012] Step S3: The computer-based analysis and calculation terminal simulates the external wall splicing and analyzes and calculates the splicing joint situation;

[0013] Step S4: After the exterior wall is hoisted and assembled on site, the drone's execution judgment end determines the location of the assembly joints that need to be repaired based on the analysis and calculation results from the computer end, and transmits the repair information to the workers.

[0014] The present invention further explains that step S2 further includes the following steps:

[0015] Step S21: When the crane starts lifting, the camera scanning module on the top of the drone performs front and side contour scans on the exterior wall splicing surface being lifted and the exterior wall splicing surface to be spliced ​​with it.

[0016] Step S22: The drone flies horizontally along the splicing surface, activates the edge detection submodule to form several infrared lasers, and vertically illuminates the side of the splicing surface for detailed scanning;

[0017] Step S22: The 3D imaging module constructs a 3D image from the outline and detail images of all the scanned exterior wall splicing surfaces;

[0018] Step S23: The storage module wirelessly transmits the constructed 3D image to the computer.

[0019] The present invention further explains that step S3 further includes the following steps:

[0020] Step S31: The cross-section simulation splicing module simulates the splicing of the two stored 3D images of the exterior wall splicing surfaces to be assembled on the computer, separates the information of splicing seams from the original images, and analyzes and calculates the splicing side images.

[0021] Step S32: On the computer, the width measurement module detects the details of the splicing surface according to the edge detection submodule of the drone and analyzes the distance between the two edges. If it exceeds the threshold, the width of the splicing seam is measured. If the distance between the two edges on the computer does not exceed the threshold, the angle measurement module measures the angle of the splicing seam.

[0022] Step S33: Based on the measured width and angle information, the calculation and analysis module calculates and analyzes the water seepage rate of the assembly joint.

[0023] The present invention further explains that the calculation formula for the water seepage rate of the assembly joint in step S34 is as follows:

[0024]

[0025] Where Q is the water seepage rate of the assembly joint, K is the conversion coefficient, W is the width of the assembly joint, V is the angle of the upper exterior wall of the assembly joint, and Y is the set threshold of the assembly joint. The width and angle of the assembly joint are the influencing factors of the water seepage rate. When W does not exceed the threshold, the above formula is satisfied. The angle of the upper exterior wall is inversely proportional to the water seepage rate. The larger the angle of the upper exterior wall, the lower the water seepage rate. When W exceeds the threshold, the following formula is satisfied. The width is directly proportional to the water seepage rate. The larger the width, the higher the water seepage rate.

[0026] The present invention further explains that step S4 further includes the following steps:

[0027] Step S41: After the exterior wall is hoisted into place on site, based on the analyzed and calculated situation of the joints on the exterior wall that need to be repaired, the drone determines the location range of the joints that need to be repaired in the factory.

[0028] Step S42: The location and range information of the assembly joints that need to be repaired are transmitted to the workers using the information transmission module so that they can carry out the repairs.

[0029] Compared with existing technologies, the beneficial effects achieved by this invention are as follows: This invention employs a scanning and storage terminal, an analysis and calculation terminal, and an execution and judgment terminal. It can scan the information of the splicing surface to a computer, form a 3D image based on the scanned contours and details, and perform simulated assembly on the computer. Based on the measured distance between the two edges, it analyzes the influence of the width and angle of the spliced ​​exterior wall. When the distance between the two edges exceeds a certain threshold, water will flow into the splicing joint under the action of surface tension of the splicing wall. When the distance between the two edges does not exceed a certain threshold, water will flow into the splicing joint along the wall surface under the action of gravity. This allows for the calculation of the water seepage rate of the splicing joint. The location information of the splicing joints that need repair is transmitted to the workers for advance repair. This setting reduces the repair cost after assembly and effectively ensures the water-proof quality of the spliced ​​wall. Attached Figure Description
