Description

Technical Field

[0002] In the construction of large-scale water slides in my country, pier-type slides and cross-beam slides are two common types. The cross-beam slide has obvious advantages in many aspects. In terms of economy, it may be more reasonable in terms of material use and construction cost compared with other types of slides, and can effectively reduce construction costs; from the perspective of construction risk, perhaps its structural design or construction technology can reduce the potential risks and hidden dangers that may occur during the construction process and improve construction safety; in terms of construction period, its unique structure and construction process may help shorten the overall construction period; for environmental protection, it may have less impact on the surrounding environment during construction, which is more in line with environmental protection requirements. However, the construction accuracy control requirements of the cross-beam slide are quite high, which is a major challenge it faces. The construction accuracy of the cross-beam covers two key parts: prefabrication accuracy and installation accuracy. The prefabrication accuracy is related to the dimensional accuracy and shape regularity of the cross-beam in the factory prefabrication stage, while the installation accuracy affects the matching degree of the cross-beam with other structures during on-site installation and the stability of the overall structure. Unfortunately, at present, in the field of construction, there is a lack of construction methods specifically designed to effectively control the prefabrication accuracy of the criss-cross beams.

[0023] In the preferred embodiment, the left inner core template 501 and the right inner core template 506 are connected to the side template 301 of the outer mold frame 3 through multiple longitudinal tie rods 12.

[0024] In the preferred embodiment, a plurality of three-way jacks 7 are provided on both sides of the bottom of the mobile trolley 8, and a support pad 6 is provided on one side of each of the three-way jacks 7; The roller at the bottom of the mobile trolley 8 is also provided with a driving motor 801, and the driving motor 801 is connected to the roller.

[0025] The mobile trolley 8 provides a moving function for the entire mold. The driving motor 801 drives the rollers to move on the track 9, which facilitates the conversion of the mold between different construction positions.

[0026] The three-way jack 7 is used to adjust the levelness and elevation of the bottom mold 1 to ensure the accuracy of mold installation. During the mold positioning process, the bottom mold 1 is first leveled by the three-way jack 7. After the vertical track axis direction and elevation are leveled, the support pad 6 is in place to support the entire mobile trolley 8, and then the three-way jack 7 is removed.

[0027] The fixed end formwork frame 2, the outer formwork frame 3 and the movable end formwork frame 4 are all connected to the corresponding formwork through a demoulding screw, which facilitates the removal of the formwork after the concrete is poured. For example, the outer formwork frame 3 is connected to the side formwork 301 through the second demoulding screw 303 and the third demoulding screw 304, which not only ensures the stability of the formwork during pouring, but also facilitates demoulding.

[0028] The special structural design of the movable inner core mold frame 5, such as the cooperation of the hinged fourth wing mold plate 504 and the bevel block 505, enables it to be flexibly operated during the mold assembly and demolding process.

[0029] The structural design of the movable end concave mold frame 10 plays a specific molding and connecting role in the mold through the connection between the third wing mold plate 1001 and the movable end concave mold plate 1003 and the connection with the movable inner core mold frame 5, ensuring that the shape and structure of the cross beam during the prefabrication process meet the design requirements.

[0030] Example 2 Further illustrate with reference to Example 1, Figure 1-10 For the structure shown, the prefabrication yard of the zigzag beam should include: steel bar processing area, zigzag beam prefabrication area, zigzag beam pre-assembly area, and zigzag beam temporary storage area; The steel bar processing area is provided with a steel bar pedestal matching the cross beam; The special prefabrication yard for the cross beam is provided with a gantry crane 13, and the method comprises: S1, the first set of mobile trolleys 8 are positioned, moved and positioned along the axis direction of the track 9, and the three-way jack 7 is in place; S2. Use the three-way jack 7 to level the bottom mold 1 and adjust the vertical track axis direction and elevation; S3, the support pad 6 is in place, the three-way jack 7 is removed, and the support pad 6 supports the entire mobile trolley 8; S4, the fixed end side template 201 and the fixed end concave template 202 of the fixed end mold frame 2 are accurately positioned and installed; S5, the side templates 301 of the two sets of outer formworks 3 are accurately positioned and installed; S6, the movable side template 402 of the movable end mold frame 4 is accurately positioned and installed; S7. The steel cage is hoisted into the mold, accurately positioned, and fixed after ensuring the thickness of the protective layer; S8, the left inner core template 501 and the right inner core template 506 of the movable inner core template 5 are accurately positioned and installed, and then the movable end inner concave mold frame 10 is installed through the transverse tie rod 11, and connected and fixed with the side template 301 through the longitudinal tie rod 12; S9, pouring precast beams, and removing the two sets of outer formworks 3 after the strength reaches the requirements, and the specific order is carried out according to the principle of "installing later and removing first"; S10, after the two sets of outer mold frames 3 and the movable inner core mold frame 5 are dismantled, the three-way jack 7 is in place and the support pad 6 is removed; S11, using the three-way jack 7, the mobile trolley 8 is placed on the track 9; S12, moving the cast precast beam to the matching beam position by means of the first movable set trolley 8; The second set of mobile trolleys is lifted to the precast beam position by the gantry crane, and steps S1 to S3 are repeated to accurately position the second set of trolleys at the precast beam; S13, the first movable set of trolleys 8 at the matching beam is adjusted by taking the second set of trolleys at the precisely positioned precast beam as the standard through steps S1 to S3 to achieve the purpose of matching the precast beam with the matching beam; S14, repeat steps S4 to S7 to accurately position and install the fixed end formwork 2 and two sets of outer formworks 3, the steel cage, and the movable inner core formwork 5, and repeat step S9 to cast the precast beam; S15, the strength of the beam to be matched reaches 75% of the design strength, and is transferred to the pre-assembly area of ​​the crisscross beam by the lifting equipment 13 for pre-assembly, and the first set of trolleys 1 is hoisted aside to be installed at the prefabricated beam; S16, remove the prefabricated beam support pads and move the prefabricated beam section to the matching beam section. Use a gantry crane to lift the first set of trolleys 1 to the prefabricated beam position, and repeat steps S1 to S9 to continue the construction of the next prefabricated cross beam.

[0031] 1. Advantages of construction process The construction process is systematic and orderly, starting from the positioning of the mobile trolley 8, and then the leveling of the bottom mold 1, the positioning of the support pad 6 and other operations are carried out in sequence, and each step is closely connected.

[0032] After the first set of mobile trolleys 8 are accurately positioned along the axis of the track 9 and the three-way jacks 7 are in place, the levelness and elevation of the bottom mold 1 are accurately adjusted by the three-way jacks 7, and then the mobile trolleys 8 are supported by the pads 6, ensuring the stability of the mold installation foundation, providing an accurate benchmark for subsequent template installation, reducing the error accumulation caused by an uneven or unstable foundation, and improving the overall construction accuracy.

[0033] The formwork is installed in the order of fixed end formwork 2, outer formwork 3, and movable end formwork 4, and is fixed after the steel cage is hoisted into the mold and accurately positioned to ensure the thickness of the protective layer. Finally, the movable inner core formwork 5 and related connecting parts are installed. This order helps to ensure the accurate position of each component in the mold and the structural integrity and dimensional accuracy of the cross-shaped beam.

[0034] Removing the formwork after concrete pouring follows the principle of "installing last and removing first", which is beneficial to protecting the formed precast beam structure and avoiding damage to the beam body due to improper removal sequence. It also facilitates the removal operation of the formwork and improves the turnover efficiency of the formwork.

[0035] The cast precast beams are moved to the matching beam positions using the mobile trolleys 8, and the first set of mobile trolleys 8 are adjusted based on the accurately positioned second set of trolleys, to achieve precise matching between the precast beams and the matching beams, thereby ensuring the connection accuracy between the cross beams and improving the stability and reliability of the overall structure.

[0036] After the strength of the matching beam reaches 75% of the design strength, pre-assembly is carried out, and the lifting and reuse of the trolley are reasonably arranged, which improves the utilization rate of construction equipment. At the same time, the pre-assembly link helps to discover and solve potential problems in advance, further ensuring the construction quality.

[0037] 2. Advantages of synergy with mold structure The structural features of each component in the mold cooperate with the construction method. For example, the outer mold frame 3 is connected to the side mold plate 301 through a demoulding screw at a specific position, which can not only ensure the stability of the side mold plate 301 during pouring, but also facilitate removal at the appropriate time according to the construction process. The connection method between the movable inner core mold frame 5 and other components, such as connecting with the movable end inner concave mold frame 10 through a transverse tie rod 11, and connecting the longitudinal tie rod 12 with the side mold plate 301 of the outer mold frame 3, ensures the coordinated work of each component at different construction stages in the construction process, ensures the integrity and stability of the mold structure, and thus improves the accuracy and quality of the prefabrication of the cross beam.

[0038] The three-way jack 7 and the drive motor 801 at the bottom of the mobile trolley 8 play a key role in the construction process. The three-way jack 7 provides a guarantee for the precise leveling of the bottom mold 1, while the drive motor 801 facilitates the movement of the mobile trolley 8 on the track 9, making the conversion of molds between different areas of the prefabrication site more convenient and efficient, closely integrating with the entire construction process and improving construction efficiency.

[0039] Example 3 Further illustrate with reference to Example 2, Figure 1-10 For the structure shown, before the construction of each cross-shaped beam, the template system should be accurately positioned. The positioning method of the template system should be combined with the template structure and process requirements, and fixed measurement control points should be set. By measuring the plane position and elevation of the measurement control points, the template and the matching beam section should be adjusted to the preset fixed position; The template uses a total station and a laser radar to perform point cloud scanning on the measurement control points to obtain three-dimensional point data, and detects whether the position of the template reaches the preset position based on artificial intelligence vision and total station positioning; The method is: A1. Set up at the construction site according to the template structure and process requirements Fixed survey control points; these points are scanned using a total station and lidar to obtain each survey control point ( ) three-dimensional coordinate data; here is only the original data acquisition, no specific formula derivation; these data are the basis for subsequent calculations and are used to determine the benchmark of the entire positioning system; A2. Use artificial intelligence visual technology to identify the template Reference points ( ), and use the total station to measure its actual coordinates; similarly, this step is mainly to obtain data; the data of these template reference points will be used for comparative analysis with the measurement control point data to determine the position status of the template; A3. Construct relative coordinate matrix: calculate each template reference point Relative to each survey control point The relative coordinate vector ; Assume that the components of the relative coordinate vector in the x, y, and z directions are ,but: ; ; ; Relative coordinate matrix , where each row corresponds to the relative coordinate vector of a measurement control point and all template reference points; the role of this matrix is ​​to fully describe the positional relationship between the template reference point and the measurement control point, which is convenient for subsequent various position analysis and judgment; Calculate the relative distance matrix based on the relative coordinate vector , where the relative distance The calculation is done using the following formula: ; This formula is used to accurately quantify the spatial distance between each template reference point and the measurement control point. By analyzing this distance matrix, we can intuitively understand the position deviation of the template in space, which is an important basis for judging whether the template has reached the preset position. A4. Template position judgment stage: For each template reference point , calculate its average relative distance to all measured control points : ; Average relative distance vector ; This vector comprehensively reflects the overall distance between each template reference point and the measurement control point. By comparing it with the preset threshold, it can be preliminarily determined whether the template position meets the requirements; Calculate the position deviation vector Relative to the ideal position; let the average position of the measured control points be ,in: ; ; ; The components of the position deviation vector in the x, y, and z directions are: ; ; ; Position deviation vector ; This vector can further analyze the deviation direction and size of the template reference point relative to the ideal position, providing more detailed information for template adjustment; A5. Template position determination: Setting position deviation threshold ; If for all template reference points , both have and ,in, is the direction deviation threshold, then it is considered that the template has reached the preset position; Otherwise, the template position does not meet the requirements and needs to be adjusted. Here, by comprehensively considering the average relative distance and the modulus length of the position deviation vector, it is possible to more comprehensively and accurately judge whether the template position is qualified. A6. Template position adjustment stage: For template reference points that do not reach the preset position , calculate the adjustment vector ; Assuming that the adjustment strategy is to adjust in the opposite direction of the position deviation vector, and the adjustment amount is proportional to the deviation amount, then: ; ; ; This adjustment vector specifies the amount by which the template reference point needs to be adjusted in each direction. This vector can be used to guide construction personnel to make precise adjustments to the template. The template is adjusted according to the calculated adjustment vector; after the adjustment is completed, the data collection and preprocessing stage, the relative position relationship calculation stage and the template position judgment stage are repeated again to re-detect the template position until the template reaches the preset position.

[0040] 1. Accuracy and comprehensiveness of positioning methods Fixed measurement control points are set in combination with the template structure and process requirements, and three-dimensional point data is obtained through total stations and laser radars. In addition, artificial intelligence vision and total station positioning are used to detect the template position. This multi-technology integration method greatly improves the accuracy of positioning. The point cloud scanning of total stations and laser radars can accurately obtain the three-dimensional coordinates of measurement control points, providing high-precision basic data for subsequent calculations. For example, these detailed and accurate three-dimensional coordinate data are like establishing an accurate three-dimensional coordinate system for the construction site, so that the position of the template can be accurately located and analyzed in this coordinate system.

[0041] Artificial intelligence vision technology recognizes reference points on the template, supplements total station measurement, and obtains template information from different angles. The combination of the two can provide a more comprehensive understanding of the template status, avoid errors or blind spots that may exist in a single measurement method, and further improve the reliability of positioning detection.

[0042] 2. Scientific advantages of algorithmic calculation Construct the relative coordinate matrix and relative distance matrix, and analyze the positional relationship between the template reference point and the measurement control point through a series of calculations. Formula for calculating the relative coordinate vector , , And the relative distance formula , which can accurately quantify the spatial distance between each template reference point and the measurement control point. This allows construction workers to intuitively understand the position deviation of the template in space from the data, providing a scientific and accurate basis for judging whether the template has reached the preset position.

[0043] In the template position judgment stage, calculate the average relative distance The calculation of the position deviation vector comprehensively considers the relationship between the template reference point and multiple measurement control points, and evaluates the template position from multiple dimensions, both overall and local. By comparing the average relative distance and the modulus length of the position deviation vector with the preset threshold, this comprehensive judgment method can more accurately determine whether the template meets the requirements, reduce the possibility of misjudgment, and ensure construction accuracy.

[0044] 3. Reasonableness and advantages of adjustment strategy For template reference points that have not reached the preset position, the way to calculate the adjustment vector is reasonable. Assume that the adjustment strategy is in the opposite direction of the position deviation vector and the adjustment amount is proportional to the deviation amount (such as , , ), this method can accurately calculate the adjustment amount according to the actual deviation of the template, making the template adjustment more targeted and effective. Construction personnel can accurately adjust the template based on these calculation results, quickly adjust the template to the preset position, improve construction efficiency, and ensure that the position accuracy of the adjusted template meets the requirements.

[0045] The mechanism of re-testing after adjustment is improved, and a closed-loop control is formed by repeating the stages of data collection and preprocessing, relative position relationship calculation and template position judgment. This ensures that the template can eventually reach the preset position and guarantees the accuracy of the template system positioning before the construction of each cross-shaped beam, thereby improving the quality and accuracy of the entire cross-shaped beam construction and laying a good foundation for subsequent construction procedures.
