Description

Technical Field

[0001] This application belongs to the field of building construction, and in particular relates to a water immersion curing device for steel-concrete composite members. Background Technology

[0002] Concrete curing refers to the process of ensuring that concrete continues to hydrate and develops the mechanical properties and durability required by the design under appropriate temperature and humidity conditions after concrete is poured. Its core essence lies in providing sufficient moisture and suitable temperature for the continuous hydration reaction of cement.

[0003] Existing technology, such as a curing adjustment device for large-volume concrete components and its usage method (201910188931.1), relates to the field of curing technology for large-volume concrete components. It addresses the problem that in existing curing construction of large-volume concrete components, relying on manual watering cannot achieve uninterrupted work and makes it difficult to guarantee the pouring quality of the large-volume concrete components. It includes: water pipes laid on the surface of the large-volume concrete component; multiple spray heads, each connected to the water pipes, with at least one spray head on each surface of the large-volume concrete component; a first temperature sensor controller located inside the large-volume concrete component; a second temperature sensor controller located on the surface of the large-volume concrete component; and a control box connected to the first and second temperature sensors, and connected to the electric valve of the water pipes.

[0004] During the curing process of steel-concrete composite columns, if the internal moisture is insufficient, the concrete strength will be lower than the design value, and shrinkage cracks will also occur. If the temperature difference between the inside and outside of the concrete at the steel section is too large, temperature cracks will occur, affecting the structural stability and normal use.

[0005] Therefore, proper maintenance of steel-concrete composite columns is crucial. Traditional maintenance methods for steel-concrete composite columns mainly include water spraying, applying curing agents, and covering with burlap sacks, non-woven fabric, or plastic film. Water spraying, covering with burlap sacks, non-woven fabric, and plastic film require regular watering by personnel and rely on the experience and ability of the construction workers, which has certain limitations. On the other hand, applying curing agents can affect the adhesion of subsequent decorative layers.

[0006] To overcome the above problems, it is necessary to develop a water immersion curing device for steel-concrete composite columns. This device would provide sufficient moisture for the cement hydration reaction through water immersion curing, reduce the temperature difference between the inside and outside of the concrete, prevent temperature cracks, and ensure structural stability and normal serviceability. Summary of the Invention

[0007] The purpose of this application is to address the shortcomings of existing technologies in the curing of steel-concrete composite columns by disclosing a water immersion curing device for steel-concrete composite columns. This device can measure the internal temperature of the concrete in real time and adjust the water temperature accordingly. The steel-concrete composite column is immersed in water, providing sufficient moisture and a suitable temperature for the continuous hydration reaction of cement.

[0008] The objective of this application is achieved through the following technical solution: A water immersion curing device for steel-concrete composite members, the device comprising: Cylindrical template, water temperature controller, data processor, first temperature sensor, second temperature sensor; The steel-concrete composite column to be cured is placed inside the cylindrical formwork, which is then filled with water to completely submerge the concrete of the column. Several first temperature sensors are cast inside the steel-concrete column to be cured, for use in monitoring the internal temperature of the steel-concrete column to be cured; The second temperature sensor is immersed in the water within the cylindrical template to measure the water temperature. The water temperature controller is externally connected to the cylindrical template and is used to adjust the water level inside the cylindrical template. Furthermore, the water temperature controller, the first temperature sensor, and the second temperature sensor are respectively connected to the data processor. The data processor, based on the collected temperature information and the preset control algorithm, completes the control of the water temperature controller, thereby realizing the temperature control of the steel-concrete column to be cured.

[0009] According to a preferred embodiment, the data processor calculates the average internal temperature of the concrete based on the temperature data collected by each first temperature sensor. When the difference between the average internal temperature of the concrete and the water temperature is greater than 25°C, the data processor turns on the water temperature controller to adjust the water temperature until the temperature difference is less than or equal to 25°C.

[0010] According to a preferred embodiment, the inlet port of the cylindrical template is equipped with a float valve. The float valve is flush with the water level control line. When the water level in the cylindrical template is lower than the control line, the float valve falls and opens the inlet valve by its own gravity to replenish the water source. As the water source is replenished, the float valve continues to rise by buoyancy, causing the inlet valve to close.

[0011] According to a preferred embodiment, the immersion curing device for steel-concrete composite members further includes: a plurality of copper clips, the ends of which are connected to copper wires. Each copper clip is held on the exposed steel structure wing plate of the steel-concrete composite column to be cured, and the ends of the copper wires are placed in the water inside the cylindrical template, thereby dissipating heat from the interior of the steel-concrete composite column to be cured.

[0012] According to a preferred embodiment, the immersion curing device for steel-concrete composite members further includes: a plurality of U-shaped clamps, the ends of which are connected to vertically arranged copper pipes, the copper pipes being filled with isopentane as a coolant, and the U-shaped clamps being clamped onto the exposed steel structure flanges of the steel-concrete composite column to be cured.

[0013] According to a preferred embodiment, the process of heat dissipation inside the steel-concrete composite column to be cured using a U-shaped clamp includes: When the temperature at the point where the bottom of the copper tube contacts the U-shaped clamp exceeds 27.7°C, isopentane vaporizes. When the temperature at the top of the copper tube is below 27.7°C, isopentane liquefies and flows back into the copper tube. This cycle of evaporation and condensation repeats, thus achieving the effect of heat dissipation.

[0014] According to a preferred embodiment, the bottom end of the cylindrical template is provided with a drainage pipe, and the drainage pipe is provided with a drainage valve.

[0015] According to a preferred embodiment, the cylindrical template is composed of two semi-circular wooden templates joined together, with one side of the template having a groove and the other side having a protrusion; the inner side of the cylindrical template is coated with waterproof paint.

[0016] According to a preferred embodiment, the outer side of the cylindrical template is provided with several round steel clamps, which are used to fasten the two semi-circular wooden templates.

[0017] According to a preferred embodiment, the round steel clamp consists of two semi-circular steel strips, which are connected and fixed by two bolts.

[0018] The aforementioned main solution and its various further alternative solutions can be freely combined to form multiple solutions, all of which are solutions that can be adopted and are claimed in this application. Those skilled in the art, after understanding the solution of this application, will realize that there are many combinations based on the prior art and common general knowledge, all of which are technical solutions to be protected in this application, and will not be exhaustively listed here.

[0019] The beneficial effects of this application are: The structure of the device in this application enables real-time monitoring of the internal and external temperatures of the concrete, allowing for the adjustment of the water temperature accordingly. This reduces the temperature difference between the inside and outside of the concrete, preventing temperature cracks and ensuring structural stability and normal serviceability. Furthermore, the immersion of the steel-concrete column in water provides sufficient moisture and a suitable temperature for the continuous hydration reaction of the cement.

[0026] Furthermore, it should be noted that unless otherwise specified in this application, the specific structures, connections, positions, power sources, etc. involved are all things that a person skilled in the art can know without creative effort based on the prior art.

[0027] Example 1: refer to Figures 1 to 4 As shown in the figure, a water immersion curing device for steel-concrete composite members is illustrated. The water immersion curing device for steel-concrete composite members includes: a cylindrical template 7, a water temperature controller 3, a data processor 4, a first temperature sensor 5, and a second temperature sensor 12.

[0028] The steel-concrete composite column to be cured is placed inside the cylindrical formwork 7, and the cylindrical formwork 7 is filled with water to completely submerge the concrete of the steel-concrete composite column to be cured. Several first temperature sensors 5 are cast inside the steel-concrete column to be cured, for use in monitoring the internal temperature of the steel-concrete column to be cured; The second temperature sensor 12 is immersed in the water in the cylindrical template 7 to measure the water temperature. The water temperature controller 3 is externally connected to the cylindrical template 7 and is used to adjust the water quality inside the cylindrical template 7. Furthermore, the water temperature controller 3, the first temperature sensor 5, and the second temperature sensor 12 are respectively connected to the data processor 4. The data processor 4, based on the collected temperature information and the preset control algorithm, completes the control of the water temperature controller 3, thereby realizing the temperature control of the steel-concrete column to be cured.

[0029] Preferably, the data processor 4 calculates the average internal temperature of the concrete based on the temperature data collected by each first temperature sensor 5. When the difference between the average internal temperature of the concrete and the water temperature is greater than 25°C, the data processor 4 turns on the water temperature controller 3 to adjust the water temperature until the temperature difference is less than or equal to 25°C.

[0030] Preferably, the inlet 8 of the cylindrical template is equipped with a float valve 6, which is flush with the water level control line. When the water level inside the cylindrical template 7 is lower than the control line, the float valve 6 falls and opens the inlet 8 valve by its own gravity, replenishing the water source. As water is replenished, the float valve 6 continues to rise due to buoyancy, causing the inlet 8 valve to close. This achieves real-time automated replenishment of water inside the cylindrical template.

[0031] Preferably, the immersion curing device for steel-concrete composite members further includes: a plurality of copper clips 9, the ends of which are connected to copper wires 91. Each copper clip 9 is clamped onto the exposed steel structure flange of the steel-concrete composite column to be cured, and the ends of the copper wires 91 are placed in the water inside the cylindrical formwork 7, thereby dissipating heat from the interior of the steel-concrete composite column to be cured. Specifically, a copper clip 9 is clamped at 200mm intervals at the position where the flange is exposed on the upper part of the steel column.

[0032] Preferably, the immersion curing device for steel-concrete composite members further includes: a plurality of U-shaped clamps 10, the ends of which are connected to vertically arranged copper pipes. The copper pipes contain isopentane as a coolant, and the U-shaped clamps 10 are clamped onto the exposed steel structure flanges of the steel-concrete composite column to be cured. Specifically, when the heat dissipation effect of the copper clamps 9 is not significant, a U-shaped clamp 10 is clamped at 200mm intervals along the flanges of the steel column.

[0033] Furthermore, the heat dissipation process inside the steel-concrete column to be cured via the U-shaped clamp 10 includes: When the temperature at the contact point between the bottom of the copper tube and the U-shaped clamp 10 exceeds 27.7℃, isopentane vaporizes. When the temperature at the top of the copper tube is below 27.7℃, isopentane liquefies and flows back into the copper tube. This cycle of evaporation and condensation repeats, thus achieving the effect of heat dissipation.

[0034] During the hydration reaction of concrete, most of the heat of hydration is conducted to the steel column. Therefore, by using copper clips 9 and U-shaped clips 10 to dissipate heat from the exposed part of the upper part of the steel column, the temperature difference between the inside and outside of the concrete is reduced.

[0035] Preferably, the bottom end of the cylindrical template 7 is provided with a drain pipe, and the drain pipe is provided with a drain valve 2.

[0036] Preferably, the cylindrical template 7 is made of two semi-circular wooden templates joined together, with a groove on one side of the template and a protrusion on the other side; the inner side of the cylindrical template 7 is coated with waterproof paint.

[0037] Preferredly, the outer side of the cylindrical template 7 is provided with several round steel clamps 1, which are used to fasten the two semi-circular wooden templates.

[0038] Furthermore, the round steel clamp 1 is composed of two semi-circular steel strips, each 50mm wide and 5mm thick, with a 9mm through hole at the end of each strip, and the strips are connected by two M8 bolts.

[0039] The structure of the device in this application enables real-time monitoring of the internal and external temperatures of the concrete, allowing for the adjustment of the water temperature accordingly. This reduces the temperature difference between the inside and outside of the concrete, preventing temperature cracks and ensuring structural stability and normal serviceability. Furthermore, the immersion of the steel-concrete column in water provides sufficient moisture and a suitable temperature for the continuous hydration reaction of the cement.

[0040] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
