Description

Technical Field

[0001] This utility model relates to a temperature control template structure for low-temperature environments. Background Technology

[0002] The hydration reaction of concrete is a crucial process for its strength gain and performance development, and this reaction requires suitable temperature conditions. At low temperatures, the hydration rate of cement particles slows down significantly or even stops. At a normal temperature of 20°C, concrete may reach a certain strength within 7 days, but at around 0°C, the same concrete may show very limited strength gain even after 28 days. This is because the hydration reaction requires water, and low temperatures cause water to freeze, hindering the chemical reaction between cement and water, resulting in slow strength development and preventing the concrete from reaching the design strength requirements within the specified time. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a low-temperature environment temperature-controlled template structure, so that the poured concrete can undergo hydration reaction at a suitable temperature to reach the design strength requirements within a specified time.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a low-temperature environment temperature control template structure, including a template frame, thermal insulation cotton wrapped around the template frame circumferentially, several positioning frames installed around the template frame circumferentially, and several electric heating tapes wrapped around the template frame circumferentially and installed on the positioning frames. The thermal insulation cotton is placed on the outermost layer to wrap the template frame, positioning frames, and electric heating tapes. After the thermal insulation cotton is wrapped, a first opening and a second opening are formed. The first opening and the second opening are fixed to the template frame with tape to form a closed opening.

[0005] As a further improvement of this utility model, the positioning frame has several wire grooves arranged along its length, and several electric heating tapes are respectively installed in the several wire grooves and are interference-fitted to the wire grooves.

[0006] As a further improvement of this utility model, the positioning frame is provided with a bayonet, which is positioned by deforming and engaging with the template frame.

[0007] As a further improvement of this utility model, the positioning frame includes a head and several connecting parts. The wire groove is provided on the connecting parts. The bottom of the head and the connecting parts are provided with slots. The side of the connecting parts away from the slots is provided with a locking block for cooperating with the slots. The head and the connecting parts, and the connecting parts and the connecting parts are fixed together by the cooperation of the slots and the locking blocks.

[0008] As a further improvement of this utility model, the first opening is fixed to the template frame by several pressure plates.

[0009] The beneficial effects of this utility model are: by setting several positioning frames on the template frame, the heating belt can be quickly installed and positioned, and the insulation cotton on the outside of the heating belt can improve the overall insulation performance.

[0014] The present invention will now be described in further detail with reference to the embodiments shown in the accompanying drawings.

[0015] Reference Figure 1-3 As shown, a low-temperature environment temperature control template structure includes a template frame 1, insulation cotton 2 wound around the circumference of the template frame 1, several positioning frames 3 installed around the circumference of the template frame 1, and several electric heating tapes 4 wound around the circumference of the template frame 1 and installed on the positioning frames 3. The insulation cotton 2 is placed as the outermost layer to wrap the template frame 1, positioning frames 3, and electric heating tapes 4. After being wrapped, the insulation cotton 2 forms a first opening 5 and a second opening 6, which are fixed to the template frame 1 with tape to form a closed opening. The insulation cotton 2 wound around the circumference of the template frame 1 can effectively reduce heat loss, play a good insulation role, and reduce the impact of the low-temperature environment on the internal structure. The positioning frames 3 installed around the circumference of the template frame 1 provide installation positions for the electric heating tapes 4, ensuring that the electric heating tapes 4 can be arranged according to design requirements. After the electric heating tapes 4 are installed on the positioning frames 3, the insulation cotton 2 wraps the outermost layer to wrap all components, forming a relatively closed space and further enhancing the insulation effect. After the insulation cotton 2 is wrapped, the first opening 5 and the second opening 6 are fixed to the template frame 1 with tape to form a closed opening, which further restricts the intrusion of air in the low temperature environment and prevents heat loss.

[0016] The positioning frame 3 has several grooves 7 arranged along its length, and several electric heating tapes 4 are respectively installed in the grooves 7 and are interference-fitted to the grooves 7. This arrangement ensures that the electric heating tapes 4 are evenly distributed on the positioning frame 3, preventing the electric heating tapes 4 from tangling or moving randomly, and ensuring the stability of the installation of the electric heating tapes 4.

[0017] The positioning frame 3 is provided with a bayonet 8, which is positioned by deforming and engaging with the template frame 1. During installation, simply align the bayonet 8 of the positioning frame 3 with the corresponding position on the template frame 1, and apply a certain external force to deform the bayonet 8 to engage the positioning frame 3 with the template frame 1, without the need for installation tools or complicated installation steps.

[0018] The positioning frame 3 includes a head 9 and several connecting parts 10. A groove 7 is provided on each connecting part 10. Both the head 9 and the bottom of each connecting part 10 have a slot 11. A locking block 12 for engaging with the slot 11 is provided on the side of each connecting part 10 away from the slot 11. The head 9 and connecting parts 10, as well as the connecting parts 10 themselves, are fixed together by the engagement of the slot 11 and the locking block 12. By modularizing the positioning frame 3, its length can be flexibly combined. The total length of the positioning frame 3 can be adjusted by increasing or decreasing the number of connecting parts 10 to accommodate different specifications of template frames 1. Furthermore, the engagement of the slot 11 and the locking block 12 facilitates the quick installation and disassembly of the mounting frame.

[0019] The first opening 5 is fixed to the template frame 1 by several pressure plates 13. This arrangement allows the pressure plates 13 to apply pressure evenly to the first opening 5 of the insulation cotton 2, ensuring that the first opening 5 is tightly fitted to the template frame 1, preventing the insulation cotton 2 from becoming loose or having gaps at the opening, thereby effectively preventing cold air from entering from the opening, ensuring the insulation performance of the insulation cotton 2, and the use of pressure plates 13 to fix some multi-layered insulation cotton 2 can effectively fix it, thus providing reliable fixation.

[0020] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
