Description

Technical Field

[0001] The invention relates to the technical field of steel box girder structure bridge construction, and in particular to a method for controlling the appearance line shape of a cast box girder. Background Art

[0002] Under the current trend, the construction of roads and bridges in basic transportation construction is applied in cities. For example, the construction of roads and bridges and viaducts can bring great convenience to urban development. With the large-scale construction of urban roads and bridges, new construction technologies have emerged. As the main structure of road and bridge construction, box beams are the main components of road and bridge construction. The current technical development trend is to complete on-site pouring at the construction site through modular prefabrication of the main road and bridge to increase construction efficiency. However, related technical problems brought about by the prefabricated and modular construction of main components such as box girders also arise, namely, the continuous linear control of construction assembly, that is, the control of the overall appearance of the splicing construction and the linear accuracy of the appearance specifications during the construction process, which directly affects the quality accuracy of prefabricated construction and modular assembly construction. In the relevant prior art, the traditional measurement method using an artificial hand-held prism is used to measure the linear control points, which has low measurement efficiency. The linear control points require multiple observations and have large point errors, which cannot meet the high-precision measurement requirements. In response to this problem, a Chinese invention patent application with publication number CN112781575A proposes a fixed-point device and a measurement method for the linear control points of prefabricated segmental beams. In this technical solution, a reflector is used, and the reflector is marked with a center point. For the fixed-point of the linear control points of the prefabricated segmental beams, the measurement of the linear control points is completed with high precision and efficiency. However, it is obvious that there are manual measurement parts in the installation configuration and positioning process, which still generates a high workload and recording workload, and the control of the measurement points is highly targeted. The matching degree is not high in collaborative large-scale construction, and it is difficult to efficiently cope with construction scenarios. Summary of the invention

DETAILED DESCRIPTION

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention; it should be noted that in this application, for the convenience of description, the "left side" in the current view is the "first end", the "right side" is the "second end", the "upper side" is the "first end", and the "lower side" is the "second end". The purpose of such description is to clearly express the technical solution, and it should not be understood as an improper limitation on the technical solution of this application.

[0019] The present invention aims to solve the technical problem of the lack of efficient and reliable casting box girder appearance linear control method that can adapt to complex construction scenes in the prior art, and provide the casting box girder appearance linear control method. The complex construction scene in this application specifically refers to that since the linear control method provided by the prior art is mainly based on manual detection, in the on-site casting and the initial stage of construction completion, in order to detect the key positions of linear control, such as the first transfer position S1001 and the second transfer position S1002, the manual detection method has the practical problems of large errors and low efficiency, and also involves the connection construction of the front casting section 6 and the matching section 7. In order to solve this problem, the technical solution of the control method provided by the present technical solution is: Step S1, arranging a casting box girder appearance linear detection control device on both sides of the casting box girder 1, the box girder casting inner mold 4 and the current casting section 6, and starting the detection to obtain the measurement coordinates or distance length; That is, the technical features and advantages of the present application are to use the same type of casting box girder appearance linear shape detection control device to complete the detection of the cross-section direction, that is, the casting box girder 1 cross-section, and the subsequent connection direction of the casting box girder 1, that is, the overlap of the spliced ​​structural joints constructed by the front casting section 6 and the matching section 7, so as to obtain the measurement coordinates or distance length of the corresponding position through the casting box girder appearance linear shape detection control device; Afterwards, the measured coordinates are drawn into a line to form a linear detection diagram, and the sizes of the first transfer position S1001 and the second transfer position S1002 are compared with the design requirements; among them, for the current casting section 6 and the matching section 7, the maximum distance is obtained to determine whether the structural joint 8 overlaps, so as to control the splicing line shape.

[0020] Please see attached Figure 8 As shown in , the casting box girder appearance linear detection control device can obtain the preset X-axis coordinate unchanged and measure and obtain multiple preset Y-axis coordinates in the casting box girder 1 section, that is, for the first transfer position S1001 and the second transfer position S1002, or obtain the preset Y-axis coordinate unchanged and measure and obtain multiple preset X-axis coordinates; For example: (X0, Y1), (X0, Y2) (X0, Y3)... (X0, Yn); Another example: (X1, Y0), (X2, Y0) (X3, Y0)... (Xn, Y0); Such continuous measurement can realize the measurement of the arc and slope changes of the first transfer position S1001 and the second transfer position S1002, and obtain actual reference measurement parameters; and The preset X-axis coordinate remains unchanged. When multiple preset Y-axis coordinates are obtained, the preset X-axis coordinate can be adjusted. The preset Y-axis coordinate remains unchanged, and multiple preset X-axis coordinates are obtained by measurement. The preset Y-axis coordinate can be adjusted; The above method can realize re-inspection, re-testing and verification, efficient detection, and control of the line shape; In addition, the cast box girder appearance linear shape detection control device is still used for the construction of the structural joint 8, that is, the splicing construction of the matching section 7. It is only necessary to align the arc notch 401 of the positioning block 40 with the structural joint of the matching section 7. Then, during the detection, a unique maximum distance will be obtained, that is, the distance from the detection infrared emission position to the arc notch 401. If the structural joint 8 between the front casting section 6 and the matching section 7 does not match, the maximum detection distance cannot be obtained, that is, it is judged that the overlap degree of the structural joint 8 between the front casting section 6 and the matching section 7 does not meet the requirements. Therefore, the advantage of this method is that it has low requirements for the configuration of the auxiliary settings that the current detection relies on. The detection of different linear shape control requirements can be achieved by only relying on the arrangement of the cast box girder appearance linear shape detection control device. In the present application, different linear shape controls are reflected in the transfer position of the cast box girder 1, that is, the key position point of the appearance; and the splicing linear shape detection of the structural joint 8 between the current casting section 6 and the matching section 7.
