Description

Technical Field

[0001] This application relates to the technical field of concrete curing, and in particular to a tall concrete curing structure. Background Technology

[0002] In engineering construction, the application of large-volume concrete is becoming increasingly widespread, such as in large foundations, dams, and bridge piers. Due to the high heat of hydration and poor heat dissipation of large-volume concrete, it is more prone to cracking, thus affecting the safety and durability of the structure. Therefore, the curing of large-volume concrete is crucial.

[0003] The main measures for curing large-volume concrete include: watering the concrete surface and, depending on the actual requirements, pre-embedding cooling pipes inside the concrete. This serves two purposes: first, to maintain the concrete under suitable temperature and humidity conditions to prevent shrinkage cracks from forming on the concrete surface due to excessive drying; and second, to circulate water into the cooling pipes to control the temperature difference between the inside and outside of the concrete and avoid excessive temperature stress that could lead to cracking.

[0004] Currently, manual watering remains one of the main methods for curing concrete. Although manual watering is relatively free and controllable, and no additional curing equipment is needed when constructing in the field, in some cases, such as when dealing with large-volume concrete at a height, construction workers need to frequently climb up and down or use scaffolding to ensure that the concrete at a high position can also be properly cured. This results in a large workload and low efficiency, which needs to be improved. Utility Model Content

[0005] The purpose of this application is to provide a tall concrete curing structure to facilitate the cooling of concrete with a relatively high height.

[0006] The present application provides a high-rise concrete curing structure with the following technical solution: including a water inlet pipe, the water inlet pipe is connected to a water outlet assembly, the water outlet assembly has several water outlets, each water outlet is connected to a water spraying assembly, each row of water spraying assemblies is distributed along the height direction of the concrete, and the water spraying assembly is used to drive water to spray in the direction of the concrete.

[0007] By adopting the above technical solution, water only needs to be injected into the inlet pipe. The water passes through the inlet pipe and the outlet component in sequence and is sprayed out from each spray component. Since each row of spray components is distributed along the height of the concrete, the water can be sprayed at different positions of the concrete, thereby achieving the cooling of the concrete, which is quite convenient.

[0008] Optionally, the water outlet assembly includes a primary branch connector connected to one end of the inlet pipe, a plurality of secondary water pipes connected to the primary branch connector, a secondary branch connector connected to each of the secondary water pipes, and a plurality of outlet pipes connected to the secondary branch connectors, wherein the outlet end is located at the end of the outlet pipe away from the secondary branch connector.

[0009] By adopting the above technical solution, water in the inlet pipe enters each auxiliary water pipe through a primary branch joint, and water in each auxiliary water pipe enters the outlet pipe through a secondary branch joint. The primary branch joint, secondary branch joint, several auxiliary water pipes, and several outlet pipes increase the water flow path, increase the contact area between water and concrete, and improve heat exchange, thereby significantly improving heat dissipation efficiency, reducing thermal stress caused by temperature changes, and thus lowering the risk of cracking. The primary branch joint controls the routing of the auxiliary water pipes, and the secondary branch joint controls the routing of the outlet pipes, reducing the occurrence of tangling.

[0010] Optionally, the inner diameter of the outlet pipe is smaller than the inner diameter of the auxiliary water pipe.

[0011] By adopting the above technical solution, the inner diameter of the outlet pipe is smaller than that of the secondary water pipe, in order to ensure water pressure and improve water flow.

[0012] Optionally, the water spray assembly includes a connector connected to the water outlet end and a maintenance nozzle threadedly connected to the connector. The connector is provided with a support portion and a first gasket is sleeved on the connector, with the first gasket located between the connector and the maintenance nozzle.

[0013] By adopting the above technical solution, after the curing is completed, the first gasket is removed, and the gap is repaired with mortar to ensure the integrity of the concrete surface and improve its aesthetics.

[0014] Optionally, the curing nozzle is provided with a main channel and several water spray channels communicating with the main channel. The diameter of the water spray channels gradually decreases in the direction away from the main channel, and the extension direction of the water spray channels is towards the concrete.

[0015] By adopting the above technical solution, water flows into the main channel through the connector and is sprayed out from each spray channel. The spray channels change the direction of water output, allowing the sprayed water to be applied to the outer surface of the concrete. The orifice diameter of the spray channels gradually decreases in the direction away from the main channel, increasing the water pressure.

[0016] Optionally, the water inlet pipe is fitted with a second gasket and two weight-increasing plates threaded onto the water inlet pipe. The second gasket is located between the two weight-increasing plates, and the two sides of the second gasket abut against the opposite side of the two weight-increasing plates, respectively.

[0017] By adopting the above technical solution, the weight-adding plate increases the weight of the water inlet pipe, resisting the buoyancy generated during concrete pouring. Before demolding, the second shim on the outer side is rotated to remove the weight-adding plate, which can be recycled.

[0018] Optionally, the water inlet pipe is fitted with a support plate, which is located between the second gasket and one of the weight-adding plates, and the support plate is located on the side of the second gasket away from the water outlet assembly.

[0019] By adopting the above technical solution, after the curing is completed, the second shim is removed, and the gap is repaired with mortar to ensure the integrity of the concrete surface and improve its aesthetics.

[0020] Optionally, the water inlet pipe includes a main water pipe and a connecting pipe connected to one end of the main water pipe. One end of the connecting pipe is connected to the water outlet assembly. The second gasket and the weight-adding plate are both connected to the connecting pipe. The connecting pipe is provided with a snap-fit ​​part, and the main water pipe is provided with a snap-fit ​​groove. The snap-fit ​​part engages with the snap-fit ​​groove.

[0021] By adopting the above technical solution, the overall length of the connecting pipe is increased through the main water pipe, allowing the connecting pipe to be connected to an external water pump. The connection between the connecting pipe and the main water pipe is convenient due to the fit between the snap-fit ​​part and the snap-fit ​​groove. During concrete pouring, the connecting pipe only needs to be poured onto the concrete, and then the main water pipe is connected to the connecting pipe, preventing the main water pipe from interfering with the pouring process.

[0022] Optionally, at least two of the snap-fit ​​parts are disposed on the connecting pipe, the number of snap-fit ​​slots is the same as the number of snap-fit ​​parts, and the snap-fit ​​parts correspond one-to-one with the snap-fit ​​slots.

[0023] By adopting the above technical solution, multiple snap-fit ​​parts are engaged with the corresponding snap-fit ​​grooves to ensure the reliability of the connection between the connecting pipe and the main water pipe and reduce the possibility of loosening or falling off.

[0024] Optionally, the connecting pipe includes an installation pipe and a connector threaded onto the installation pipe, the second gasket and the weight-adding plate are both connected to the installation pipe, and the snap-fit ​​portion is disposed on the connector.

[0025] By adopting the above technical solution, the connector is used to connect the installation pipe and the connecting pipe, making the connection more convenient.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. Simply fill the inlet pipe with water, and the water will pass through the inlet pipe and the outlet components in sequence and be sprayed out from each spray component. Since each row of spray components is distributed along the height of the concrete, the water can be sprayed at different positions of the concrete, thereby achieving the cooling of the concrete, which is quite convenient.

[0028] 2. By using a primary branch joint, a secondary branch joint, several auxiliary water pipes, and several outlet pipes, the water flow path is increased, the contact area between water and concrete is enlarged, and heat exchange is more thorough, thus significantly improving heat dissipation efficiency, reducing thermal stress caused by temperature changes, and thereby reducing the risk of cracking. The primary branch joint controls the routing of the auxiliary water pipes, and the secondary branch joint controls the routing of the outlet pipes, reducing the occurrence of tangling.
