Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to a device for alleviating cracking of fine stone concrete heating floors. Background Art

[0002] In modern construction, fine aggregate concrete is widely used for pouring floors, ground surfaces, and other structures due to its excellent workability, durability, and cost-effectiveness. In particular, in heating floor systems, fine aggregate concrete acts as a heat transfer medium, and its performance directly impacts the heating effect and service life. However, during the concrete pouring and setting process, the heat released by the cement hydration reaction causes the internal temperature of the concrete to rise significantly, while the surface temperature remains relatively low. This temperature difference between inside and outside causes thermal stress in the concrete, which in turn triggers cracking. Cracking not only affects the integrity and aesthetics of the concrete structure, but can also reduce its load-bearing capacity and durability, posing a threat to the safe use of the building.

[0003] To address this issue, existing technologies have employed several measures, such as using low-heat cement, adding retarders, and employing layered pouring methods. However, these methods often have limited effectiveness and can increase construction costs and complexity. Therefore, developing a device that can effectively mitigate cracking in fine aggregate concrete heating floors is urgently needed to improve construction quality and efficiency and ensure building safety. Utility Model Content

[0004] The purpose of the utility model is to provide a device for alleviating cracking of fine stone concrete heating floors, which is used to effectively cool the interior of concrete during the concrete pouring and solidification process, thereby reducing the temperature difference between the inside and outside and avoiding the occurrence of cracking.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is to provide a device for alleviating cracking of fine stone concrete heating floors, the device comprising:

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0021] In the description of the present invention, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0023] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, internal communication between two components, or interaction between two components.

[0024] See also Figures 1 to 2 The present invention provides a device for alleviating cracking of fine aggregate concrete heating floors, comprising a formwork 1 and a cooling system. The formwork 1 comprises a base plate 11 and side plates 12 disposed around the base plate 11. The cooling system comprises a cooling pipe 2, the edges of which are fixed to the middle of the side plates 12. The cooling pipe 2 has a water inlet 23 and a water outlet 24. The water inlet 23 of the cooling pipe 2 is connected to a cooling water source via an external pipe, and a cooling water pump is disposed on the external pipe.

[0025] The utility model sets a cooling system in the middle of the side plate 12 of the formwork 1. After the concrete is poured onto the formwork 1, the cooling pipe 2 inside the concrete can cool the inside of the concrete during the concrete solidification process. Specifically, the cooling water pump works continuously to pump the cooling water in the cooling water source into the cooling pipe 2 through the external pipe via the water inlet end 23. The cooling water flowing in the cooling pipe 2 cools the inside of the concrete, and then the cooling water is discharged from the water outlet end 24, thereby reducing the temperature difference between the surface and the inside of the concrete, thereby avoiding the phenomenon of concrete cracking due to excessive internal and external temperature difference.

[0026] In one embodiment, the cooling pipes 2 include transverse pipes 21 and longitudinal pipes 22, both of which are seamless carbon steel pipes. These seamless carbon steel pipes not only cool the interior of the concrete floor, preventing cracking caused by the large temperature difference between the inside and outside, but also increase the tensile strength of the concrete floor (similar to steel bars), further preventing cracking.

[0027] In one embodiment, the transverse pipes 21 and the longitudinal pipes 22 are closely attached, and are interconnected at their intersections. By connecting the transverse pipes 21 and the longitudinal pipes 22, a stable pipe network is formed between the transverse pipes 21 and the longitudinal pipes 22, improving the stability of the cooling pipes 2 and preventing the cooling pipes 2 from shifting or deforming during concrete pouring.

[0028] Specifically, the transverse pipe 21 and the longitudinal pipe 22 are connected by welding or bundling.

[0029] In one embodiment, a temperature sensor is further included. The temperature sensor is fixed on the cooling pipe 2 and is electrically connected to the cooling water pump. The temperature sensor measures the temperature of the concrete in real time during the solidification process and controls the output power of the cooling water pump.

[0030] In one embodiment, an insulation layer (specifically, a composite insulation material) is also included. The insulation layer covers the outer surface of the bottom plate 11 and the side plate 12 of the formwork 1 to maintain the internal temperature of the formwork 1 stable during the concrete pouring and solidification process, thereby further reducing the risk of cracking of the concrete due to temperature fluctuations.

[0031] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
