Description

[0002] In the construction of large-scale water slides in my country, pier-type slides and grid-beam slides are two common types. Grid-beam slides exhibit significant advantages in several aspects. Economically, they are more rational in terms of material usage and construction costs compared to other types of slides, effectively reducing construction costs. From a construction risk perspective, their structural design or construction process may reduce potential risks and improve construction safety. Regarding construction period, their unique structure and construction process may help shorten the overall construction cycle. In terms of environmental protection, they may have less impact on the surrounding environment during construction, better meeting environmental protection requirements. However, the construction precision control requirements for grid-beam slides are quite high, which is a major challenge. The construction precision of grid-beam slides encompasses two key aspects: prefabrication precision and installation precision. Prefabrication precision relates to the dimensional accuracy and shape regularity of the grid beams during factory prefabrication, while installation precision affects the compatibility of the grid beams with other structures and the overall structural stability during on-site installation. Unfortunately, the current construction field lacks specific methods for effectively controlling the prefabrication accuracy of grid beams. This, to some extent, restricts the full realization of the advantages of grid beam sliding tracks and brings difficulties to the high-quality construction of related projects. Utility Model Content

[0044] A movable side template 402 is provided on both sides, and an inner concave mold frame 10 with movable end is provided between them.

[0045] In the preferred embodiment, the movable end concave mold frame 10 includes a movable end concave template 1003, with a third wing template 1001 hinged at both ends of the movable end concave template 1003.

[0046] The movable end concave template 1003 of the movable end concave mold frame 10 is connected to the template of the movable inner core mold frame 5 by multiple horizontal tie rods 11.

[0047] In the preferred embodiment, the movable inner core mold frame 5 rests against the bottom mold 1. The movable inner core mold frame 5 includes two left inner core templates 501 and a right inner core template 506.

[0048] The fourth wing template 504 is connected to the left inner core template 501 through multiple sixth demolding screws 503, and the fourth wing templates 504 on both sides are connected through multiple supporting inner frames 502.

[0049] 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 by multiple longitudinal tie rods 12.

[0050] In the preferred embodiment, the bottom sides of the mobile trolley 8 are also equipped with multiple three-way jacks 7, and each of the three-way jacks 7 has a support pad 6 on one side.

[0051] The rollers at the bottom of the mobile trolley 8 are also equipped with a drive motor 801, which is connected to the rollers.

[0052] The mobile trolley 8 provides mobility for the entire mold. The rollers are driven by the drive motor 801 to move on the track 9, which facilitates the conversion of the mold between different construction positions.

[0053] The three-way jack 7 is used to adjust the level 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 using the three-way jack 7. After leveling the vertical track axis and elevation, the support 6 is positioned to support the entire moving trolley 8, and then the three-way jack 7 is removed.

[0054] The fixed end formwork 2, the outer formwork 3, and the movable end formwork 4 are all connected to the corresponding templates via release screws. The release screws facilitate the removal of the templates after the concrete has been poured and formed. For example, the outer formwork 3 is connected to the side template 301 via the second release screw 303 and the third release screw 304, which ensures the stability of the template during pouring and facilitates demolding.

[0055] The special structural design of the movable inner core mold frame 5, such as the cooperation of the hinged fourth wing template 504 and the angled block 505, allows it to operate flexibly during mold assembly and demolding. At the same time, it is connected to the movable end inner concave mold frame 10 through the transverse tie rod 11 and to the side template 301 of the outer mold frame 3 through the longitudinal tie rod 12, which enhances the integrity and stability of the entire mold structure.

[0056] The structural design of the movable end concave mold frame 10, through the connection between the third wing template 1001 and the movable end concave template 1003 and the connection with the movable inner core mold frame 5, plays a specific forming and connecting role in the mold, ensuring that the shape and structure of the grid beam in the prefabrication process meet the design requirements.

[0057] Example 2

[0058] Further explanation in conjunction with Example 1, such as Figure 1-10 The structure shown should include: a steel bar processing area, a grid beam prefabrication area, a grid beam pre-assembly area, and a grid beam temporary storage area.

[0059] The steel bar processing area is equipped with steel bar support pedestals that match the grid beams;

[0060] The prefabrication yard for the grid beams is equipped with a gantry crane 13. The method includes:

[0061] S1. The first set of mobile trolleys 8 are positioned and moved along the axis of track 9. The three-way jacks 7 are in place.

[0062] S2. Level the bottom mold 1 using the three-way jack 7, adjusting the vertical track axis direction and elevation.

[0063] S3, support 6 is in place, remove the three-way jack 7, support 6 supports the entire mobile trolley 8;

[0064] S4. After the fixed end edge template 201 and the fixed end concave template 202 of the fixed end template frame 2 are accurately positioned, they are installed.

[0065] S5. The side templates 301 of the two sets of outer formwork frames 3 are precisely positioned and then installed.

[0066] S6. After the mobile side template 402 of the mobile end mold frame 4 is precisely positioned, it is installed.

[0067] S7. The steel cage is hoisted into the formwork, precisely positioned, and fixed after ensuring the thickness of the protective layer.

[0068] S8. After the left inner core template 501 and right inner core template 506 of the movable inner core template 5 are accurately positioned, they are installed. Then, the movable end inner concave mold frame 10 is installed through the horizontal tie rod 11, and connected and fixed to the side template 301 through the longitudinal tie rod 12.

[0069] S9. After the precast beams have reached the required strength, remove the two sets of outer formwork 3. The specific order should follow the principle of "removing the last one installed first".

[0070] S10. After the two sets of outer mold frames 3 and the movable inner core mold frame 5 are removed, the three-way jack 7 is in place and the support pad 6 is removed.

[0071] S11. Using the three-way jack 7, lower the mobile trolley 8 onto the track 9;

[0072] S12. Move the cast precast beam to the matching beam position using the first moving trolley 8.

[0073] The second set of mobile trolleys is lifted to the precast beam position by a gantry crane. Steps S1 to S3 are repeated to accurately position the second set of trolleys at the precast beam.

[0074] S13. The first moving trolley 8 at the matching beam is adjusted according to the second trolley at the precast beam after precise positioning, through steps S1 to S3, so as to achieve the purpose of matching the precast beam with the matching beam.

[0075] S14. Repeat steps S4 to S7 to accurately position and install the fixed end formwork 2, the two sets of outer formwork 3, the steel cage, and the movable inner core formwork 5. Repeat step S9 to pour the precast beam.

[0076] S15. When the strength of the beam to be matched reaches 75% of the design strength, it is transferred to the pre-assembly area of ​​the grid beam by the lifting equipment 13 for pre-assembly. The first set of trolleys 1 is lifted to the side to be installed on the precast beam.

[0077] S16. Remove the precast beam support pads and move the precast beam segment to the matching beam segment. Use a gantry crane to lift the first set of trolley 1 to the precast beam position, and repeat steps S1 to S9 to continue the construction of the next precast grid beam.

[0078] 1. Advantages of the construction process

[0079] The construction process is systematic and orderly. Starting with the positioning of the mobile trolley 8, the bottom formwork 1 is leveled and the support 6 is positioned in sequence. Each step is closely connected.

[0080] After the first set of mobile trolleys 8 is precisely positioned along the axis of track 9 and the three-way jacks 7 are in place, the level and elevation of the bottom mold 1 are precisely adjusted by the three-way jacks 7. Then, the mobile trolleys 8 are supported by the support pads 6, which ensures the stability of the mold installation foundation, provides a precise benchmark for subsequent template installation, reduces the accumulation of errors caused by uneven or unstable foundations, and improves the overall construction accuracy.

[0081] The template is installed in the order of fixed end formwork 2, outer formwork 3, and movable end formwork 4, with precise positioning and installation. After the steel cage is hoisted into the formwork and precisely positioned to ensure the thickness of the protective layer, it is fixed. Finally, the movable inner core formwork 5 and related connecting parts are installed. This sequence helps to ensure the accurate position of each component in the mold and to guarantee the structural integrity and dimensional accuracy of the grid beam.

[0082] After concrete pouring, the formwork should be removed following the principle of "removing the last installed formwork first". This helps protect the already formed precast beam structure, avoids damage to the beam due to improper removal sequence, and also facilitates the removal of formwork, thus improving the turnover efficiency of the formwork.

[0083] The precast beams that have been poured are moved to the matching beam positions using the mobile trolley 8. The first set of mobile trolleys 8 is then adjusted based on the second set of trolleys that have been precisely positioned, so as to achieve precise matching between the precast beams and the matching beams. This ensures the connection accuracy between the grid beams and improves the stability and reliability of the overall structure.

[0084] Pre-assembly is carried out after the strength of the matching beam reaches 75% of the design strength. The lifting and reuse of the trolley is arranged in a reasonable manner, which improves the utilization rate of construction equipment. At the same time, the pre-assembly process helps to discover and solve potential problems in advance, further ensuring construction quality.

[0085] 2. Advantages of synergy with mold structure

[0086] The structural features of each component in the mold are coordinated with the construction methods. For example, the outer mold frame 3 and the side template 301 are connected by demolding screws at specific positions. This ensures the stability of the side template 301 during pouring and facilitates its removal at appropriate times according to the construction process. The connection between the movable inner core mold frame 5 and other components, such as the connection between the transverse tie rod 11 and the movable end concave mold frame 10, and the connection between the longitudinal tie rod 12 and the side template 301 of the outer mold frame 3, ensures the coordinated work of each component at different construction stages, guaranteeing the integrity and stability of the mold structure, thereby improving the accuracy and quality of the prefabrication of the grid beam.

[0087] The three-way jack 7 and drive motor 801 at the bottom of the mobile trolley 8 play a crucial role in the construction process. The three-way jack 7 ensures 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 the mold between different areas of the prefabrication yard more convenient and efficient. This is closely integrated with the entire construction process and improves construction efficiency.

[0088] Example 3

[0089] Further explanation in conjunction with Example 2, such as Figure 1-10 As shown in the diagram, before constructing each grid beam, the formwork system should be precisely positioned. The positioning method of the formwork system should be combined with the formwork structure and process requirements, setting fixed measurement control points. By measuring the plane position and elevation of the measurement control points, the formwork and matching beam segments are adjusted to the preset fixed positions. The measurement and control of the formwork at the measurement control points is performed using a total station and LiDAR to scan the control points to obtain three-dimensional point data. Based on artificial intelligence vision and total station positioning, the position of the formwork is detected to ensure that it has reached the preset position.

[0090] The method is as follows:

[0091] A1. Set up the formwork structure and process requirements at the construction site. There are three fixed measurement control points; these points are scanned using a total station and a lidar to obtain the measurement control point data. ( The three-dimensional coordinate data of the system; this is just the raw data acquisition, without specific formula derivation; these data are the basis for subsequent calculations and are used to determine the benchmark of the entire positioning system;

[0092] A2. Utilize artificial intelligence visual technology to identify the template. Reference points ( The actual coordinates of the template reference points are measured using a total station; similarly, this step mainly involves data acquisition; the data from these template reference points will be used for comparative analysis with the measurement control point data to determine the position and status of the template.

[0093] A3. Construct the relative coordinate matrix: Calculate the reference point for each template. Relative to each measurement control point relative coordinate vector Let the components of the relative coordinate vector in the x, y, z directions be respectively... ,but:

[0094] ;

[0095] ;

[0096] ;

[0097] Relative coordinate matrix Each row corresponds to the relative coordinate vector between a measurement control point and all template reference points; the purpose of this matrix is ​​to comprehensively describe the positional relationship between the template reference points and the measurement control points, which facilitates various positional analyses and judgments in the future.

[0098] Calculate the relative distance matrix based on the relative coordinate vectors. The relative distance Calculate using the following formula:

[0099] ;

[0100] 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 positional deviation of the template in space, which is an important basis for judging whether the template has reached the preset position.

[0101] A4. Template Position Determination Stage: For each template reference point Calculate its average relative distance with respect to all measurement control points. :

[0102] ;

[0103] 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 position of the template meets the requirements.

[0104] Calculate the position deviation vector Relative to the ideal position; let the average position of the measurement control points be... ,in:

[0105] ;

[0106] ;

[0107] ;

[0108] The components of the position deviation vector in the x, y, and z directions are:

[0109] ;

[0110] ;

[0111] ;

[0112] Position deviation vector This vector can be used to further analyze the direction and magnitude of the deviation of the template reference point from the ideal position, providing more detailed information for template adjustment.

[0113] A5. Template Position Determination: Set a position deviation threshold. If for all template reference points They all and ,in, If the directional deviation threshold is set, the template is considered to have reached the preset position.

[0114] Otherwise, the template position does not meet the requirements and needs to be adjusted. By comprehensively considering the average relative distance and the magnitude of the position deviation vector, we can more comprehensively and accurately determine whether the template position is qualified.

[0115] A6. Template Position Adjustment Stage:

[0116] For template reference points that have not reached the preset position Calculate the adjustment vector Assuming 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:

[0117] ;

[0118] ;

[0119] ;

[0120] This adjustment vector clarifies the amount that the template reference point needs to be adjusted in each direction. Based on this vector, construction workers can be guided to make precise adjustments to the template.

[0121] The template is adjusted based on the calculated adjustment vector. After the adjustment is completed, the data acquisition and preprocessing stage, the relative position relationship calculation stage, and the template position judgment stage are repeated to re-detect the template position until the template reaches the preset position.

[0122] 1. Advantages of the accuracy and comprehensiveness of the positioning method

[0123] By setting fixed measurement control points based on the template structure and process requirements, and acquiring 3D point data using a total station and LiDAR, combined with artificial intelligence vision and total station positioning to detect the template position, this multi-technology fusion approach greatly improves positioning accuracy. Point cloud scanning by the total station and LiDAR accurately acquires the 3D coordinates of the measurement control points, providing high-precision foundational data for subsequent calculations. For example, this detailed and accurate 3D coordinate data is like establishing a precise 3D coordinate system for the construction site, allowing the template position to be accurately located and analyzed within this coordinate system.

[0124] Artificial intelligence vision technology identifies reference points on the template, supplementing total station measurements. By acquiring template information from different angles, the combination of the two can provide a more comprehensive understanding of the template's status, avoiding potential errors or blind spots that may exist with a single measurement method, and further improving the reliability of positioning and detection.

[0125] 2. The scientific advantages of algorithmic computation

[0126] A relative coordinate matrix and a relative distance matrix are constructed, and the positional relationship between the template reference point and the measurement control point is analyzed through a series of calculations. The formula for calculating the relative coordinate vector is provided. , , and the relative distance formula It can accurately quantify the spatial distance between each template reference point and the measurement control point. This allows construction personnel to intuitively understand the positional 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.

[0127] During the template location determination phase, the average relative distance is calculated. The calculation of the position deviation vector comprehensively considers the relationship between the template reference point and multiple measurement control points, evaluating the template position from multiple dimensions, both overall and local. By comparing the average relative distance and the magnitude of the position deviation vector with preset thresholds, this comprehensive judgment method can more accurately determine whether the template meets the requirements, reduce the possibility of misjudgment, and ensure construction accuracy.

[0128] 3. The advantages of the rationale for adjusting the strategy

[0129] For template reference points that have not reached the preset position, the method for calculating the adjustment vector is reasonable. Assume the adjustment strategy follows the opposite direction of the position deviation vector and the adjustment amount is proportional to the deviation amount (e.g., ...). , , This method can accurately calculate the adjustment amount based on the actual deviation of the template, making template adjustment more targeted and effective. Construction workers can use these calculation results to precisely adjust the template, quickly adjusting it to the preset position, improving construction efficiency, and ensuring that the positional accuracy of the adjusted template meets the requirements.

[0130] The mechanism for re-inspection after adjustment is improved, forming a closed-loop control through stages such as repeated data collection and preprocessing, relative position calculation, and template position judgment. This ensures that the template can ultimately reach the preset position, guarantees the accuracy of the template system positioning before the construction of each grid beam, thereby improving the overall quality and precision of the grid beam construction and laying a solid foundation for subsequent construction procedures.
