Description

Technical Field

[0001] This utility model relates to the field of concrete slab curing technology, and in particular to a spraying structure for concrete slab curing. Background Technology

[0002] In the field of construction engineering, the curing quality of concrete slabs directly affects their strength, durability, and overall structural performance. After concrete is poured and formed, it is necessary to maintain surface moisture through proper curing to avoid problems such as cracking and insufficient strength caused by rapid moisture evaporation.

[0003] Currently, concrete slab curing is generally carried out manually by sprinkling water. Workers use handheld spray pipes to spray water onto the surface of the concrete slab. This traditional method is not only time-consuming and labor-intensive, but also prone to uneven water distribution due to human intervention. This results in uneven moisture distribution on the concrete slab surface, which in turn reduces the curing quality and fails to meet the refined requirements of modern construction projects for concrete strength and durability.

[0036] Two rectangular support plates 209 are each fixedly connected to a folded tube 205 on their opposite sides, and both folded tubes 205 are sleeved on the outside of the drive screw 206. The opposite ends of the two folded tubes 205 are fixedly connected to the left and right ends of the outside of the nut 207.

[0039] Example 2, based on Example 1, such as Figure 3 , Figure 4 , Figure 6 and Figure 7As shown, a rectangular opening 104 is provided on the front side of the upper end face of the support plate 1, and a reciprocating distance adjustment component 6 is provided on the upper end face of the support plate 1 above the rectangular opening 104; the reciprocating distance adjustment component 6 includes two square guide rods 601 and two buffer plates 603.

The two buffer plates 603 are slidably connected to the two adjustment plates 602 through the sliding guide rods 606, and the outside of each sliding guide rod 606 is located on the adjustment plate 602. Springs are fitted between the water pump 5 and the buffer plate 603. A push switch A604 is installed in the middle of the right end face of the left buffer plate 603, and a push switch B605 is installed in the middle of the left end face of the right buffer plate 603. The push switches A604, B605, water pump 5, motor 204, and battery 103 are all electrically connected to the controller 102.

By setting the reciprocating distance adjustment component 6, the reciprocating movement distance of the spray pipe 3 can be flexibly adjusted according to the actual working conditions such as the width of the concrete slab, which improves the flexibility of the reciprocating drive component 2 in different scenarios.

[0040] Each adjusting plate 602 has two square sliding openings, and the square sliding openings are slidably connected to the square guide rod 601. Each adjusting plate 602 has a threaded through hole 608 on both the front and rear sides, which communicates with the square sliding openings. Each threaded through hole 608 is connected to a fastening bolt 607 for fixing the adjusting plate 602.

[0041] The working principle of this embodiment is as follows: When in use, first fill the transparent water tank 4 with clean water, and then move the spraying structure to the concrete slab curing site by using the universal wheels at the lower end of the support leg 101, so that the spraying pipe 3 is located above the concrete slab to be cured. Then, start the water pump 5 by using the controller 102, and transport the clean water inside the transparent water tank 4 to the inside of the spraying pipe 3 through the water delivery hose 301. Then, spray the clean water onto the concrete slab below through the water nozzle at the bottom of the spraying pipe 3 to perform water curing on the surface of the concrete slab.

[0042] During the water spraying curing process on the concrete slab surface, the controller 102 starts the motor 204, causing the drive screw 206 to rotate forward. At this time, the nut 207, under the action of the thread, moves the reciprocating plate 201, the two pressing plates 208, and the spray pipe 3 to the left. Then, the button on the pressing switch A604 is pressed by one of the pressing plates 208 on the left. At this time, the controller 102 controls the motor 204 shaft to rotate in reverse, thereby causing the drive screw 206 to rotate in reverse. At this time, the nut 207, under the action of the thread, moves the reciprocating plate 201, the two pressing plates 208, and the spray pipe 3 to the left. The reciprocating moving plate 201, the two pressing plates 208 and the spraying pipe 3 move to the right. Then, the button on the pressing switch B605 is pressed by one of the pressing plates 208 on the right side. At this time, the controller 102 controls the motor 204 shaft to rotate forward, and the spraying pipe 3 moves to the left again. In this way, the spraying pipe 3 can move back and forth, so that when water is sprayed to cure the concrete slab, the water can be more evenly distributed on the surface, thus meeting the refined requirements of modern construction projects for concrete strength and durability.

[0043] During use, the distance of the spray pipe 3 reciprocating left and right can be adjusted according to the width of the concrete slab and other conditions. Specifically, to adjust, simply loosen the fastening bolts 607 on both sides of the two adjusting plates 602, so that the two adjusting plates 602 lose their fixing function outside the square guide rod 601. Then, move the two adjusting plates 602 left and right to adjust the distance between the press switch A604 and the press switch B605. After adjustment, tighten the fastening bolts 607, so that the distance of the spray pipe 3 reciprocating left and right can be changed, improving the flexibility of the reciprocating drive component 2 in application.
