UHPC covers are characterized by high strength, high density, and excellent crack resistance, and are suitable for structural components with extremely high requirements. The preparation and construction processes of UHPC have relatively high requirements for equipment and technology, especially in terms of achieving uniform material distribution, correct arrangement of steel fibers, and precise pouring.

[0003] After the UHPC cover is formed, it is often difficult to open easily during the demolding process. Therefore, a forming mold that can be easily opened during the demolding process is needed. Traditional molds require opening buckles, while in this case, permanent magnets are used for attraction. During demolding, it only needs to be inverted and gently tapped to demold and open the cover. If the bottom is not tapped, the permanent magnets will hold it and the cover will not open. Summary of the Utility Model

[0083] Example 4

[0084] Combined with Embodiment 2 and Embodiment 3, the forming process of the UHPC cover plate is further described. 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;

[0085] The production system includes: a demolding production line, a mold-in production line, and a transverse movement mechanism; it also includes a stacking and unstacking machine for stacking and unstacking precast component molds or finished products between the demolding production line, the mold-in production line, and the transverse movement mechanism;

[0086] The steam curing system includes: a steam curing kiln, an in-and-out kiln track, and a mother-and-son vehicle; the steam curing kiln is connected to the demolding production line through the out-kiln track and its mother-and-son vehicle;

[0087] After pouring into the mold, it needs to be sent into a special vibration device for vibration forming, and then stacked and sent into the steam curing system. In this solution, raw materials such as fine sand, coarse sand, silica fume, cement, and additives are added to the mixing hopper 201 of the mixing component 2. After adding water and mixing, it flows into the transition bin 102, and the discharge baffle 214 is closed to continue the mixing work of the next hopper;

[0088] The mixed material after mixing is transported to the slurry covering component 6 below through the pumping pump 103 and the flexible connecting pipe 104. Special steel fibers 801 are added to the vibrating disk 302 in the steel adding component 3. The steel fibers 801 are sent from the vibrating disk 302 into the guide trough 303, and finally transported to the special-shaped groove 510 of the cloth plate 504 through the distributing trough 304. The first limit 5110, the second limit 5111, and the third limit 5112 of the special-shaped groove 510 are electrified so that the steel fibers 801 cannot fall;

[0089] When the housing 701 is conveyed in by the feeding conveyor belt 407, it moves to stop above the pallet of the lifting oil cylinder 402 through the conveyor belt. At this time, the forward moving electric cylinder 601 moves the grouting nozzle 605 above 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 slurry covering. After covering the first layer of mixed material, the second lifting motor 602 controls the grouting nozzle 605 to move upward and retract. The transverse moving electric cylinder 502 drives the cloth plate 504 below to move above the groove 7011. The first lifting motor 508 lowers the cloth plate 504 above the first layer of slurry covering. At this time, the first limit 5110 and the second limit 5111 are electrified, and the third limit 5112 is de-energized. The steel fibers 801 adsorbed by the electromagnet 511 fall above the first layer of slurry covering. The cloth plate 504 moves upward and returns to its position. After returning, the second rotating motor 501 rotates the cloth plate 504 to change the cloth direction of the steel fibers 801;

[0090] Repeat the above method to make the thickness of the mixture in the groove 7011 reach the final designed thickness, complete the pouring work of the cover plate, and the cloth feeding assembly 5 and the mortar covering assembly 6 return to their original positions. Then, the vacuum suction cup 414 under the swing motor 403 sucks up 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 by a 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 oil cylinder 402 lifts the housing 701 to engage with the top cover 702, the vacuum suction cup 414 releases the top cover 702, the swing motor 403 rotates back to its original position, and the support plate of the lifting oil cylinder 402 returns to be flush with the discharge conveyor belt 406;

[0091] The object 701 with the top cover 702 covered is pushed by the pushing cylinder 416 onto the discharge conveyor belt 406 and sent to the next process. The next process is directly palletizing. After palletizing, it is sent to the initial curing room. After the initial curing is completed, the formwork is removed and sent to the final curing room, and finally the finished product is produced. Compared with the traditional production of UHPC cover plates, the vibration process can be directly omitted;

[0092] After the initial curing and final curing are completed, the staff can collect the curing parameters of each cover plate through the storage chip carried in the forming mold, including the temperature change during the curing process and the weight change of the cover plate itself, and can conduct key tests on the cover plates with unqualified parameters to prevent the outflow of defective products.

[0093] The above embodiments are only the preferred technical solutions of the present invention and should not be regarded as limitations on the present invention. The protection scope of the present invention should be the technical solutions recorded in the claims, including the equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, the equivalent replacement improvements within this scope are also within the protection scope of the present invention.
