Description

Technical Field

[0001] The present application relates to the field of building construction, and in particular to an intelligent large-volume concrete raft slab construction process, method, system and medium. Background Art

[0002] With the rapid development of the national economy, the number of buildings is increasing, and the styles of buildings are becoming more and more diverse. To meet the growing and diverse needs, building structures are mostly designed in the form of a combination of a main tower and a podium. The foundation design of engineering buildings often adopts a pile raft foundation, with engineering piles at the bottom and a flat raft foundation at the top. Conventional base plates are mostly 2m to 4m thick, with a concrete volume of around 10,000 cubic meters, which falls into the category of large-volume concrete construction. However, as building heights continue to rise, base plate thickness continues to increase, and concrete volume continues to increase. This makes the quality requirements of concrete construction very high, and the concrete demand is large, making it impossible to pour concrete in a single pour. Multiple pours may result in insufficient joint strength between concrete batches, or different strengths of concrete produced in different batches, resulting in cracking, making construction more difficult. Summary of the Invention

[0003] In order to improve the problem of high construction difficulty, the present application provides an intelligent large-volume concrete raft construction process, method, system and medium.

[0004] This application provides an intelligent large-volume concrete raft construction process, which adopts the following technical solutions:

[0005] An intelligent large-volume concrete raft construction process, comprising:

[0006] The concrete mix ratio for large-volume construction is determined through orthogonal design and trial mix tests, and the reliability of the concrete mix ratio is verified through full-scale model tests and numerical simulation analysis;

[0007] Counting the total amount of concrete required for pouring, and using the total amount of concrete and the concrete mix ratio to complete the required concrete mix in one go and continuously stir the mix;

[0008] The steel bar cutting plan is calculated based on the actual steel bar cutting information and steel bar raw material information, and the steel bars are cut, cut and installed according to the steel bar cutting plan;

[0009] The area to be poured with concrete is divided into multiple pouring layers along the pouring height, and a shifting zone is reserved at the end of each pouring layer. When pouring the current pouring layer, the shifting zone is reserved and not poured with concrete. When pouring the next pouring layer, the shifting zone of the previous pouring layer is poured;

[0010] The entire concrete surface is polished by a concrete leveling robot.

[0011] By adopting the above technical solution, after the required concrete is mixed in one batch, it needs to be stirred continuously to make the mixed concrete more uniform, and to prevent the concrete from settling after the mix is ​​completed, which will cause different strengths of different casting layers during pouring. In the layered pouring, the next casting layer is poured immediately when the current casting layer has not solidified, and the push zone of the current casting layer is poured, so that the pouring of the next casting layer and the poured part of the current casting layer can be effectively integrated. Moreover, since the poured concrete is completed in the same batch with the same composition, it avoids cracking in the later stage due to different strengths, controls the consistency of materials provided by concrete suppliers, reduces the discreteness of concrete strength, and ensures the construction quality of the base plate. The concrete base plate is poured continuously and seamlessly in one time, avoiding the setting of construction joints and temperature post-casting strips, reducing the amount of template support and multiple pouring measures, and greatly saving construction costs.

[0012] This application provides an intelligent large-volume concrete raft construction device, which adopts the following technical solutions:

[0016] The cutting mechanism receives the steel bars discharged from the storage mechanism and cuts the steel bars into required lengths.

[0017] By adopting the above technical solution, steel bars of different diameters can be automatically screened and stored separately. Then, when steel bars of a specified diameter need to be cut, the corresponding diameter steel bars can be accurately accessed through the corresponding storage structure, which is convenient and quick.

After screening by the screening component, steel bars of different diameters enter different screening hole slots to enter the corresponding storage mechanism.

Different receiving plates are engaged with the corresponding screw threads, and the pitch of the screw threads along the distribution direction increases or decreases to ensure that the spacing between adjacent receiving plates is equal.

[0023] By adopting the above technical solution, only a single steel bar is transmitted through the gap between the receiving plates, which facilitates the unloading of a single steel bar during unloading, reduces the probability of multiple steel bars entering the cutting mechanism at the same time, causing an impact on the cutting function of the cutting mechanism, and improves stability.

A unloading hole for passing the processed steel bars is provided on the reference plate. A unloading opening and closing piece for controlling the opening and closing of the opening surface of the unloading hole is slidably provided in the reference plate.

[0025] By adopting the above technical solution, the steel bar is pushed against the reference plate through the resistance plate, so that the cutting mechanism can start the initialization calculation of the steel bar length from the reference plate, which is convenient for initialization and measurement of the steel bar cutting length, making the cutting length of the steel bar more accurate, reducing the probability of different lengths of steel bars falling on the cutting table at different positions, resulting in the inability to accurately cut the specified steel bar length, and improving stability.

[0026] Optionally, the cutting table is provided with a makeshift cavity for making way for the cutting piece to cut the steel bars, a support plate is slidably provided in the makeshift cavity, the groove is also provided on the support plate to support the steel bars, a first blocking block is telescopically provided on the cutting table, a second blocking block is provided on the support plate, the first blocking block and the second blocking block are used to block the steel bars fed onto the cutting table so that the steel bars fall into the groove, an inclined surface is formed on the first blocking block, and a top block is provided on the support plate for abutting against the inclined surface to lift the first blocking block to block the steel bars.

[0027] By adopting the above technical solution, the steel bars are blocked from entering the groove by the first blocking block and the second blocking block, thereby further improving stability. The first blocking block is automatically raised by the inclined surface and the first blocking block. When the support plate slides open to make way for the cutting piece, the first blocking block automatically descends under the action of its own weight to make way, which is convenient and quick.

[0058] The following is combined with Figure 1-11 This application is described in further detail.

[0059] The present application embodiment discloses an intelligent large-volume concrete raft construction process. Figure 1 , the intelligent large-volume concrete raft construction process includes the following steps:

[0060] S1. Determine the concrete mix ratio for large-volume construction through orthogonal design and trial mix tests, and verify the reliability of the concrete mix ratio through full-scale model tests and numerical simulation analysis;

[0061] S11. Count the total amount of concrete to be poured, and mix the required concrete in one go based on the total amount of concrete and the concrete mix ratio, and then continuously stir the concrete;

[0062] S12. Calculating a steel bar cutting plan based on actual steel bar cutting information and steel bar raw material information, cutting and installing the steel bars according to the steel bar cutting plan;

[0063] S13, dividing the area to be concreted into multiple pouring layers along the pouring height, and reserving a shifting zone at the end of each pouring layer. When pouring the current pouring layer, the shifting zone is not poured with concrete, and when pouring the next pouring layer, the shifting zone of the previous pouring layer is poured.

[0064] S14. The entire concrete surface is polished by a concrete leveling robot.

[0065] In detail: After the required concrete is mixed in one batch, it needs to be stirred continuously to make the mixed concrete more uniform, and to prevent sedimentation caused by standing still after the mix is ​​completed, which will result in different strengths of different pouring layers during pouring. In the layered pouring of step S13, the next pouring layer is poured immediately before the current pouring layer is solidified, and the push zone of the current pouring layer is poured, so that the pouring of the next pouring layer can be effectively integrated with the poured part of the current pouring layer. Since the poured concrete is mixed in the same batch and has the same composition, cracking in the later stage due to different strengths can be avoided.

[0066] The embodiment of the present application discloses an intelligent large-volume concrete raft construction device. Figure 2 The intelligent large-volume concrete raft slab construction device is used to perform intelligent cutting processing on the steel bars in step S12. In this embodiment, the direction of gravity is downward, and the direction opposite to downward is upward. The intelligent large-volume concrete raft slab construction device includes a screening mechanism 1, a storage mechanism 2, and a cutting mechanism 3. The staff puts a plurality of steel bars into the screening mechanism 1, and the screening mechanism 1 is used to screen the steel bars according to different diameters. The number of storage mechanisms 2 is the same as the batches screened by the screening mechanism 1, that is, the number of storage mechanisms 2 is the same as the number of batches into which the screening mechanism 1 divides steel bars of different diameters through diameter screening. The steel bars of the same diameter batch screened by the screening mechanism 1 are stored in the same storage mechanism 2, and are used to cut steel bars of the required diameter when cutting processing is required later. The cutting mechanism 3 receives the steel bars cut by the storage mechanism 2 and cuts the steel bars into the required length.

[0067] Reference Figure 2 and Figure 3 The screening mechanism 1 includes a screening box 11, which is provided with a screening inlet 111 for feeding steel bars. A control block 112 is provided in the screening box 11 for lifting and sliding. The side wall of the end of the control block 112 is attached to the inner wall of the screening box 11, and the number of steel bars stacked from the screening inlet 111 is based on a height not exceeding the upper end surface of the control block 112. A screening slot 113 for passing the steel bars is formed between the lower end surface of the control block 112 and the bottom wall of the screening box 11. A screw rod is rotated on the screening box 11 through a bearing, and the screw rod is inserted into and threadedly connected to the control block 112. A handwheel for rotation by the staff is fixed on the end of the screw rod outside the screening box 11. The screw rod is rotated to control the lifting and lowering of the control block 112 to ensure that only one steel bar enters the screening slot 113.

[0068] Reference Figure 3A screening path 12 is formed on the inner wall of the screening box 11, and the steel bars enter the screening path 12 from the screening inlet 111 through the screening groove 113, and the bottom wall of the screening inlet 111, the bottom wall of the screening groove 113 and the bottom wall of the screening path 12 are all inclined downward, that is, the lowest end of the screening inlet 111 is connected to the highest end of the screening groove 113, and the highest end of the screening groove 113 is connected to the lowest end of the screening path 12.

[0069] Reference Figure 4 The screening path 12 is equipped with multiple screening assemblies 13. In this embodiment, there are three screening assemblies 13, evenly distributed along the extension direction of the screening path 12. The screening path 12 also defines a plurality of screening slots 14, each connected to a different storage mechanism 2. Each screening slot 14 corresponds one-to-one with each storage mechanism 2, and each screening slot 14 corresponds one-to-one with each screening assembly 13. In other words, in this embodiment, there are three screening slots 14, three screening assemblies 13, and three storage mechanisms 2. The screening assembly 13 includes a screening plate 131 and a screening spring 132. The screening path 12 also defines a blocking slot 15, which communicates with the screening slots 14. The screening plate 131 slides within the blocking slot 15. One end of the screening spring 132 is fixedly connected to the inner wall of the blocking slot 15, and the other end of the screening spring 132 is fixedly connected to the screening plate 131. The screening spring 132 expands and contracts in a direction that pushes the screening plate 131 toward the opening of the screening slot 14. The bottom wall of the screening plate 131 is larger than the opening of the screening slot 14. After being hit by the steel bar, the screening plate 131 slides open the opening surface of the screening hole slot 14 and compresses the screening spring 132. The cross-sectional diameter of the opening surface of the screening hole slot 14 is larger than the diameter of the steel bar allowed to pass.

[0070] Reference Figure 3 and Figure 4 and Figure 5The screening plate 131 is provided with an adjustment plate 133 on the side wall of the screening slot 113, and a control rod 134 is rotated inside the screening plate 131. The control rod 134 passes through the side wall of the screening box 11 to the outside, and two first worm gear teeth 135 are sleeved on the control rod 134. The first worm gear teeth 135 rotate coaxially with the control rod 134. A plurality of adjustment slots 136 for engaging with the first worm gear teeth 135 to control the lifting and lowering of the adjustment plate 133 are opened on the side wall of the adjustment plate 133 facing the control rod 134, and the adjustment slots 136 are evenly distributed along the sliding direction of the adjustment plate 133. The control rod 134 is located on the end of the outside of the screening box 11 and is fixedly connected to a turntable 137. The control rod 134 is located at the position outside the screening box 11 and is also rotatably sleeved with an insert disk 16. The insert disk 16 is sleeved on the control rod 134 and only limits the sliding of the insert disk 16 while allowing the insert disk 16 to rotate. The insert disk 16 is located between the side wall of the screening box 11 and the turntable 137. The insert disk 16 is fixedly connected to a limiting rod 161 facing the side wall of the screening box 11. A limiting groove 162 is provided on the outer wall of the screening box 11 for the limiting rod 161 to be inserted and slided and to limit the rotation of the insert disk 16. The limiting groove 162 extends along the sliding direction of the screening plate 131. A pull rod 138 slides on the rotary disk 137, and the pull rod 138 slides in a direction toward or away from the screening box 11. The insert disk 16 is provided with a plurality of slots 114 for inserting the pull rod 138 to limit the rotation of the control rod 134. The slots 114 are evenly distributed along the circumference of the insert disk 16. A return spring is also sleeved on the pull rod 138. One end of the return spring abuts or is embedded in the pull rod 138, and the other end of the return spring abuts against the side wall of the rotary disk 137 facing the insert disk 16. The return spring is used to pull the pull rod 138 in the direction of inserting the slots 114.

[0071] Reference Figure 3 and Figure 4 When the radius of the steel bar hitting the adjustment plate 133 is smaller than the adjustment plate 133 and the screening plate 131, the steel bar hitting the adjustment plate 133 will not generate any force in other directions, but will simply push the screening plate 131 to slide and then enter the storage mechanism 2 through the screening slot 14. When the radius of the steel bar hitting the adjustment plate 133 is larger than the adjustment plate 133 and the screening plate 131, the steel bar hits the outer wall of the adjustment plate 133 at its highest point, which is slightly below the center of the adjustment plate 133. This will generate an oblique upward force at the top of the adjustment plate 133, causing the steel bar to pass over the adjustment plate 133 and continue to roll downward.

[0072] Reference Figure 6The storage mechanism 2 includes a storage box 21, which corresponds one-to-one to the screening hole slot 14. The screening hole slot 14 is connected to the top of the storage box 21. A plurality of receiving plates 22 are staggeredly installed in the storage box 21. The steel bars on the previous receiving plate 22 roll down to the next receiving plate 22, and the spacing between adjacent receiving plates 22 is equal. A worm gear 23 and an adjusting rod 25 rotate in the storage box 21. The adjusting rod 25 is also fixedly provided with a second worm gear tooth 24 that meshes with the worm gear 23. The second worm gear tooth 24 is used to drive the adjusting rod 25 to rotate. A plurality of screw threads 251 are provided on the adjusting rod 25. In this embodiment, there are three receiving plates 22, which are staggered, that is, the number of receiving plates 22 on the same side is one or two. Therefore, the number of screw threads 251 on an adjusting rod 25 is two or one, and the plurality of screw threads 251 are distributed along the length direction of the adjusting rod 25. Different receiving plates 22 are meshed with corresponding screw threads 251. The pitch of the screw threads 251 along the distribution direction increases or decreases to ensure that the spacing between adjacent receiving plates 22 is equal. In this embodiment, there are two worm gears 23 in a storage box 21, and one worm gear 23 passes through the side wall of the storage box 21 to the outside, and a handwheel for rotation by the staff is fixed on the end of the worm gear 23 located outside the storage box 21, and there are two adjusting rods 25 located on the same side of the receiving plate 22, that is, one receiving plate 22 corresponds to two adjusting rods 25, and the two adjusting rods 25 are respectively engaged with the two worm gears 23, and the worm gear 23 with the handwheel fixed is also engaged with a linkage rod 231, and the linkage rod 231 is engaged with the worm gear 23 by worm gear engagement, and a bevel gear is provided on the other worm gear 23, and the end of the linkage rod 231 away from the handwheel is engaged with the bevel gear of the other worm gear 23 through the bevel gear to achieve synchronous rotation. The pitch of different screw threads 251 is to ensure that the spacing between adjacent receiving plates 22 is still equal after movement. For example, in this embodiment, the three receiving plates 22 from top to bottom are named A, B, and C, with an initial spacing of Y. The rising speed of A is X1, and the spacing between the top wall of the storage box 21 and A decreases at a speed of X1, that is, Y-X1*t. If the spacing between B and A is to be equal to the spacing between the top wall and A, in the process of A moving up at a speed of X1, B needs to move up at a speed of 2*X1, that is, the spacing between A and B is Y+X1*t (A moves away from B at a speed of X1)-2*X1*t (B approaches A at a speed of 2*X1)=Y-X1*t, so as to ensure that the spacing between the top wall and A is equal to the spacing between A and B, and the same is true for C. Therefore, the pitch of the screw thread 251 needs to be larger the lower the screw thread 251 is.The receiving plate 22 at the bottom is rotatably connected to an opening plate, and a motor for driving the opening plate to rotate is also installed on the receiving plate 22. The rotation of the motor drives the opening plate to rotate, thereby controlling the opening plate to fit and close with the inner wall of the storage box 21 or to open the opening plate and form a gap with the inner wall of the storage box 21 to allow the steel bars to leave the storage box 21 for unloading.

The second stop block 363 is fixedly connected to the support plate 361 at a position away from the first stop block 362. The first stop block 362 and the second stop block 363 are used to block the steel bars fed onto the cutting table 31 so that the steel bars fall into the groove 32. The first stop block 362 is formed with an inclined surface 364 on the side wall facing the support plate 361. The inclined surface 364 is inclined in a downward direction as it moves away from the support plate 361. A top block 365 is fixedly connected to the side wall of the support plate 361 facing the first stop block 362. The top block 365 is used to be inserted into the inner wall of the makeshift cavity 36 near the first stop block 362, so that the top block 365 is pressed against the inclined surface 364 to push the first stop block 362 upward to block the steel bars. In this embodiment, when the support plate 361 abuts against the side wall of the clearance cavity 36 away from the reference plate 33, the first blocking block 362 is located at the coordinate point one-third away from the reference plate 33 and the second blocking block 363 is located at the coordinate point one-third close to the reference plate 33, with one-third and two-thirds of the total length of the groove 32 as coordinate points. In other embodiments, the positions of the first blocking block 362 and the second blocking block 363 may also be different.

[0078] S21, determining a steel bar cutting plan based on steel bar cutting information and steel bar raw material information;

[0079] S22, determining the corresponding control signal according to the steel bar cutting plan and outputting it to the storage mechanism 2 and the cutting mechanism 3.

[0080] Details: The steel bar cutting plan is automatically calculated based on the steel bar cutting information and steel bar raw material information. The staff can install the cut steel bars according to the steel bar cutting plan.

[0081] Reference Figure 11 , step S21 further includes the following steps:

[0082] S3. Determine the steel bar strength based on the steel bar cutting area and the building strength requirements, and determine the required steel bar length, required steel bar diameter, and steel bar distribution quantity based on the steel bar strength;

[0083] S31. Determine the maximum value of the steel bar distribution quantity based on the number of steel bars, determine the maximum value of the required steel bar length based on the number of steel bars and the steel bar length, and determine the interval value of the steel bar diameter and the interval value of the steel bar distribution quantity based on the maximum value of the steel bar distribution quantity and the maximum value of the required steel bar length;

[0084] S32. The steel bar raw material information also includes a price list, and a total price range is determined by the price list, the range values ​​of the steel bar distribution quantity, and the range values ​​of the steel bar diameter;

[0085] S33. Obtain an optimal total price value through the total price interval value, and determine an optimal length of steel bars, an optimal distribution number of steel bars, and a corresponding optimal diameter of steel bars through the optimal total price value;

[0086] S34, and output the optimal length of the steel bars, the optimal distribution number of the steel bars and the corresponding optimal diameter of the steel bars as cutting signals to the cutting mechanism 3 for cutting.

[0087] In detail: the steel bar cutting area is the area where steel bars need to be installed in the current construction, and the building strength is the strength of reinforced concrete required in the current construction project. The steel bar strength is determined by these two, and the steel bar strength here is the comprehensive strength of the steel bar, including the strength brought by the length of the steel bar, the strength brought by the diameter of the steel bar and the strength brought by the density of the steel bar distribution; the steel bar raw material information can be imported in the form of a table, and the number of steel bars is the number of steel bars that can be cut at present or the number of steel bars in the warehouse, which is specifically the number of steel bars that can be put into the screening mechanism 1 and stored in the storage mechanism 2 after screening. The steel bar diameter represents the diameter data of the currently existing steel bars, and the steel bar length represents the length data of the currently existing steel bars, and the steel bar diameter corresponds to the steel bar length and the number of steel bars, that is, how many steel bar diameters The number of steel bars corresponds to the number of steel bars, and the length of the steel bars in the steel bars of this number of steel bar diameters is how much; first, the density of the steel bars is determined by the number of steel bars when all the steel bars are used and evenly distributed for installation, which is the maximum value of the steel bar distribution number, and then the maximum value of the steel bar length is determined from the steel bar length, that is, the length of the cut steel bar cannot be greater than the length of the shortest steel bar. Then, the steel bar distribution number is combined with the comprehensive strength of the steel bars to calculate the interval value of the steel bar diameter and the interval value of the steel bar length. For example: if there are ten steel bars with lengths of 5-5.9m, and one bar every 0.1m, then the maximum length of the cut steel bar is 5m, because 5m of steel bar cannot be cut into 5.1m, and steel bars larger than 5m can be cut into 5m, and the construction area is 3m 2 , then the maximum number of steel bar distribution is root / m 2 If the diameters of the ten steel bars are of two kinds, that is, five steel bars have a diameter of 5 cm and five steel bars have a diameter of 6 cm, the comprehensive strength of the steel bars can be calculated as At this time, the comprehensive strength of the steel bars can be combined with the building strength requirements and the price list. If the optimal total price is set as the lowest price, then the steel bar diameter can be selected, or the steel bar length can be cut, or the number of steel bars can be reduced, so that the lowest steel bar price is used to make the comprehensive strength of the steel bars still within the range of the building strength requirements; or if the goal is to minimize the loss rate of raw steel bars, then the calculation will be carried out with the least number of cutting times as the goal, thereby obtaining a new steel bar cutting plan.
