Problems solved by technology

[0003] Aiming at the problem that the assembly accuracy and quality of the butt joint planes of existing concrete prefabricated components are difficult to guarantee, the purpose of the present invention is to provide a quality detection and treatment method for the butt joint interface of prefabricated components, which uses three-dimensional scanning technology to obtain the verticality deviation and The flatness deviation of the docking interface, and then the processing parameters of the docking interface of the prefabricated components to be installed are obtained through virtual assembly technology, so that the precision control of the docking plane is implemented in the production stage of the prefabricated components to be installed, which not only improves production efficiency, but also effectively improves the docking plane. Assembly accuracy and quality

Embodiment 1

[0033] Example one: figure 1 Shown is the assembly design of two concrete prefabricated components. The first prefabricated component a at the lower part is connected to the bottom plate 3, and the second prefabricated component b at the upper part is vertically aligned and connected with the first prefabricated component a, and the bottom is combined Figure 1 to Figure 5 Explain the quality detection and treatment method of the docking interface of the prefabricated component of the present invention, and the specific steps are as follows:

[0034] S1: Perform a three-dimensional scan of the first prefabricated component a installed on the bottom plate 3 at the construction site, and send the three-dimensional scan data to a background processing system (not shown in the figure), and the background processing system generates the first prefabricated component based on the three-dimensional scan data The actual three-dimensional graphics 1';

[0035] S2: Such as image 3 As shown, ...

Embodiment 2

[0039] Embodiment 2: Combination Figure 1-Figure 4 , Figure 6-Figure 8 Describe the quality detection and treatment method of the prefabricated component docking interface of the present invention. The difference from the first embodiment is that after the second prefabricated component b is processed according to the adjustment parameters given by the background processing system, the second prefabricated component b docking interface When the flatness still cannot meet the assembly design requirements, the specific steps of the method are as follows:

[0040] S11: Perform a three-dimensional scan of the first prefabricated component a installed on the bottom plate 3 at the construction site, and send the three-dimensional scan data to the background processing system, which generates the actual three-dimensional graphics 1'of the first prefabricated component according to the three-dimensional scan data, Such as figure 2 Shown, comparative analysis of the design model of the...

Abstract

The invention provides a prefabricated part butt joint interface quality detection and treatment method and relates to the field of assembly type construction. The method comprises the following steps: performing three-dimensional scanning on the installed first prefabricated part and generating an actual three-dimensional graph of the first prefabricated part by a background processing system; and performing the virtual assembly of the actual three-dimensional graph of the first prefabricated part and the design model graph of a second prefabricated part to be installed on the background processing system, and comparing and analyzing whether deviation exists between the perpendicularity of the first prefabricated part and the second prefabricated part and the flatness of the butt joint interface, and when no deviation exists, directly processing the second prefabricated part to be installed and entering the next step; and when deviation exists, calculating an adjusting parameter for machining the butt joint interface of the second prefabricated part to be installed, and machining and manufacturing the second prefabricated part to be installed, and completing the maintenance; conveying the second prefabricated part to a construction site, and completing the assembling construction of the first prefabricated part and the second prefabricated part according to the requirement ofthe assembled design diagram.

Description

Technical field [0001] The invention relates to the technical field of prefabricated construction, in particular to a method for detecting and disposing of the quality of the docking interface of a prefabricated component. Background technique [0002] The control of the assembly accuracy of the prefabricated structure is mainly through the control of verticality and elevation, while less attention is paid to the splicing quality of the docking plane of the concrete prefabricated components. At present, the docking plane of the concrete prefabricated components is mainly achieved through methods such as cement plastering. Flatness control, this method not only increases the workload of the construction personnel, but also the assembly accuracy and quality of the docking plane is difficult to guarantee. Summary of the invention [0003] Aiming at the problem that the assembly accuracy and quality of the existing concrete prefabricated component docking plane is difficult to guarant...
