Description

Technical Field

[0001] This invention relates to the field of UHPC cover plates, and in particular to a UHPC cover plate layer casting equipment and cover plate forming method. Background Technology

[0002] In modern architecture and civil engineering, UHPC (Ultra-High Performance Concrete) is attracting increasing attention due to its superior mechanical properties and durability. UHPC cover plates are characterized by high strength, high density, and excellent crack resistance, making them suitable for structural components with extremely high requirements. The preparation and construction process of UHPC requires high-level equipment and technology, especially in achieving uniform material distribution, correct steel fiber arrangement, and precise casting.

[0003] Traditional UHPC cover plate manufacturing typically involves manual or semi-automatic processes. These processes make it difficult to ensure material homogeneity and proper fiber distribution, and also lack the ability to control the environment and monitor material properties. Traditional methods face problems of low efficiency and high cost when mass production and large-scale application.

[0004] To overcome these challenges, a layered casting equipment and molding method for UHPC cover plates was developed. Through a precise control system, the equipment can effectively disperse and orient steel fibers, ensuring the structural performance of the UHPC cover plates. The introduced temperature and weight monitoring technology enables real-time monitoring of the entire casting process, ensuring product quality and providing valuable data support. The original vibration process has been eliminated, which not only optimizes the production process but also improves the overall performance of UHPC cover plates and the economic benefits of production.

[0086] Example 2

[0087] Further explanation in conjunction with Example 1, such as Figure 1-23 The structure shown illustrates a method for forming a cover plate using the aforementioned UHPC cover plate layer casting equipment. The method includes:

[0088] S1. Place the housing 701 of the molding die 7 on the feeding conveyor belt 407;

[0089] S2. Use the grouting assembly 6 to apply the first grouting to the bottom of the shell 701;

[0090] S3. Using fabric assembly 5, lay steel fiber 801 above the first grouting.

[0091] S4. Use the grouting assembly 6 to perform a second grouting above the steel fiber 801;

[0092] S5. Rotate the fabric assembly 5, adjust the direction of the steel fiber 801 and lay the steel fiber 801;

[0093] S6. Repeat steps S2-S5 until the thickness of the cover plate 8 inside the housing 701 meets the design requirements.

[0094] S7. After the cover plate thickness meets the standard, the vacuum suction cup 414 moves the top cover 702 to the top of the housing 701 and aligns it, and the lifting cylinder 402 lifts the housing 701 and fastens it with the top cover 702.

[0095] S8. After the locking is completed, the lifting cylinder 402 descends, and the pushing cylinder 416 pushes the forming mold 7 onto the discharge conveyor belt 406 to transport it to the next process.

[0096] In the preferred embodiment, in step S1, the molding die 7 includes a housing 701, a detachable top cover 702 is provided on the top of the housing 701, a groove 7011 is provided in the center of the housing 701, a plurality of slots 7012 are provided around the groove 7011, and a permanent magnet is provided at the bottom of the slot 7012.

[0098] The outer side of the card slot 7012 is also provided with a square closed sealing groove 7015, which corresponds to the shape of the sealing piece 7021.

[0099] The sealing groove 7015 also has multiple silicone teeth 7014 inside;

[0100] The bottom of the groove 7011 is also provided with a weighing sensor 7016, and the inner walls around the groove 7011 are also embedded with a temperature sensor 7013. The weighing sensor 7016 is used to detect the weight change during the cover plate forming process, and the temperature sensor 7013 is used to record the temperature change during the cover plate forming process.

[0101] The information detected by the weighing sensor 7016 and the temperature sensor 7013 is stored in a memory chip and collected and uploaded by workers using a PDA device after molding.

[0102] In the preferred embodiment, in step S3, the steel fiber 801 is multi-bent, and the two ends of the steel fiber 801 are provided with end hooks 8011, and multiple elastic bends 8012 are provided between the end hooks 8011. The main function of the end hooks 8011 and the elastic bends 8012 is to improve the tensile properties and post-cracking toughness of the cover plate.

[0103] Example 3

[0104] In conjunction with Examples 1 and 2, the molding process of UHPC cover plates is further explained. Conventional UHPC cover plates require a conveying system, a production system, and a steam curing system. The conveying system includes a mixing station and conveying equipment.

[0105] The production system includes: a mold ejection production line, a mold infeed production line, and a transverse transfer mechanism; it also includes a stacking and destacking machine for stacking and destacking prefabricated component molds or finished products between the mold ejection production line, the mold infeed production line, and the transverse transfer mechanism.

[0106] The steam curing system includes: a steam curing kiln, inlet and outlet tracks, and mother and daughter cars; the steam curing kiln is connected to the mold production line via the outlet track and its mother and daughter cars;

[0107] After being poured into the mold, it needs to be sent to a special vibration equipment for vibration molding, and then stacked and sent into the steam curing system. In this scheme, the raw materials fine sand, coarse sand, silica fume, cement and admixtures are added to the mixing bucket 201 of the mixing component 2, water is added and mixed, and then it flows into the transition bin 102. The discharge baffle 214 is closed and the mixing work of the next bucket is continued.

[0108] The mixed material is pumped by pump 103 and flexible connecting pipe 104 to the slurry covering component 6 below. Special steel fiber 801 is added to the vibrating plate 302 in the steel adding component 3. The steel fiber 801 is fed into the guide trough 303 by the vibrating plate 302 and finally conveyed to the special groove 510 of the distribution plate 504 through the distribution trough 304. The first limit 5110, the second limit 5111 and the third limit 5112 of the special groove 510 are energized to prevent the steel fiber 801 from falling.

[0109] When the housing 701 is conveyed in by the feeding conveyor belt 407, it moves to the top of the support plate of the lifting cylinder 402 and stops. At this time, the forward moving electric cylinder 601 moves the grouting nozzle 605 to the top of the groove 7011. The second lifting motor 602 controls the grouting nozzle 605 to move downward to the bottom of the groove 7011 for the first grouting. After covering the first layer of mixture, the second lifting motor 602 controls the grouting nozzle 605 to move upward and then back, driven by the transverse moving electric cylinder 502. The lower fabric plate 504 is moved to the top of the groove 7011. The first lifting motor 508 lowers the fabric plate 504 to the top of the first layer of cover slurry. At this time, the first limit switch 5110 and the second limit switch 5111 are energized, and the third limit switch 5112 is de-energized. The steel fiber 801 attracted by the electromagnet 511 falls to the top of the first layer of cover slurry. The fabric plate 504 moves up and returns to its original position. After returning to its original position, the second rotary motor 501 rotates the fabric plate 504 to change the fabric direction of the steel fiber 801.

[0110] Repeat the above process until the thickness of the mixture in the groove 7011 reaches the final designed thickness, and complete the pouring of the cover plate. The material distribution assembly 5 and the slurry covering assembly 6 return to their original positions. Then, the vacuum suction cup 414 below the swing motor 403 lifts the top cover 702 at the top cover conveyor belt 408. During the rotation of the swing motor 403, the moving motor 411 moves to the preset position, and the first rotating motor 412 rotates at the preset angle so that when the top cover 702 rotates above the housing 701, it is just aligned with the housing 701. At this time, the lifting cylinder 402 lifts the housing 701 and fastens it to the top cover 702. The vacuum suction cup 414 releases the top cover 702, the swing motor 403 returns to its original position, and the support plate of the lifting cylinder 402 returns to be flush with the discharge conveyor belt 406.

[0111] The object 701 with the top cover 702 is pushed onto the discharge conveyor belt 406 by the pusher cylinder 416 and sent to the next process. The next process is to stack directly. After stacking, it is sent to the primary curing chamber. After primary curing is completed, it is demolded and sent to the final curing chamber to finally produce the finished product. Compared with the traditional UHPC cover plate production, the vibration process can be directly omitted.

[0112] After the initial and final curing are completed, staff can use the storage chip carried in the molding mold to collect the curing parameters of each cover plate, including temperature changes and weight changes of the cover plate itself during the curing process. This allows for targeted testing of cover plates whose parameters do not meet the standards, preventing defective products from being released.
