Description

Technical Field

[0001] This utility model relates to the field of precast concrete component curing technology, and more specifically, to a heat-insulating and humidity-controlled precast concrete component curing device. Background Technology

[0002] In the curing of precast concrete components, heating curing and open-air curing are generally used. Open-air curing is greatly affected by weather changes and is not conducive to factory assembly line operations. Traditional curing kiln curing uses steam or electric heating and the curing kiln insulation uses ordinary materials, resulting in poor insulation effect. Steam curing has high temperature, uneven local temperature, and is difficult to control, which also affects the precast concrete components. Steam costs are also high. Although electric heating curing can control the temperature, humidification is difficult, heat exchange energy consumption is high, and it has a significant impact on the precast concrete components, making them prone to cracking.

[0003] The production of large bridge precast components is usually carried out on-site, adapting to local conditions. However, the aforementioned curing methods are costly and difficult to meet the needs of on-site production. Therefore, the traditional methods of setting up spray pipes on the surface of precast components for curing or using manual point spraying are commonly used. These traditional curing methods result in high labor intensity and labor costs. Furthermore, the rough spraying method makes it difficult to ensure uniform curing and relatively poor control of temperature and humidity during the curing process. As a result, the quality of precast components varies.

[0004] Therefore, it is necessary to propose a heat-insulating and humidity-controlled curing device for precast concrete components, which is of great significance for improving the curing quality of precast components. Utility Model Content

[0012] Based on the above scheme, the main frame tube has an arc-shaped cross-section and is placed on the outer edge of the precast concrete component or on the inner edge of the precast concrete component.

[0021] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0022] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0023] Please see Figure 1 and combined Figure 2 and Figure 3 As shown, this utility model discloses a heat-insulating and humidity-controlled curing device for precast concrete components, comprising a frame 1 and a film 14. The frame 1 is designed in an inverted U-shape, and the film 14 covers the surface of the frame 1. When the inner edge of the precast concrete component needs to be cured, the film 14 covers the surface of the frame 1, forming a space with open ends between the film 14 and the precast concrete component to be cured. When the outer edge of the precast concrete component needs to be cured, the frame 1 is placed on the outer edge of the precast concrete component to be cured, and the film 14 covers the surface of the frame 1, forming a space with open ends between the film 14 and the precast concrete component to be cured. In order to reduce the loss of moisture and temperature in the space, in practice, a curtain (not shown) can be set on the surface of the open ends to form a relatively closed space.

[0024] Specifically, the frame 1 of this utility model is provided with guide rails 20 on both sides along the length of the frame 1. A spray frame 30 adapted to the shape of the precast concrete component is mounted on the guide rails 20. A roller 41 driven by a motor 42 is installed at the bottom of the spray frame 30. The roller 41 is adapted to the guide rails 20. When the motor 42 drives the roller 41 to rotate, the spray frame 30 will verify the movement of the guide rails 20 to achieve uniform curing of the surface of the precast concrete component. During the curing process, it is only necessary to control the output force of the motor 42 to achieve automated curing.

[0025] In this invention, the spray frame 30 is an interconnected tubular structure, with multiple spray heads 31 mounted on it. The spray frame 30 is connected to a water pump via a water supply pipe 40. When the spray frame 30 moves along the guide rail 20, it can move along the length of the precast component. The water pump, through the water supply pipe 40 and the spray heads 31, can spray the surface of the precast component.

[0026] Compared with the prior art, the present invention has the following advantages: 1. Compared to natural curing by sprinkling water, the film 14 covering combined with the spray system can keep the temperature and humidity constant, prevent cracks and accelerate strength formation, which is beneficial to the turnover rate of the bottom mold.

[0027] 2. Energy-saving and environmentally friendly: Compared with traditional steam curing, it consumes very little energy.

[0028] 3. Improved economic efficiency: Compared with natural watering maintenance, the use of a sprinkler system saves labor costs and improves economic efficiency.

[0029] In one embodiment of this utility model, prefabricated components are disposed on the outside of frame 1. Supports 10 are mounted on the outer edges of both sides of frame 1. The supports 10 consist of four points, one at the start point and one at the end point on each side of frame 1. Each support 10 has supporting ribs connected to frame 1 to enhance its strength. Guide rails 20 are mounted on the outside of the supports 10, and a U-shaped groove 13 is provided on the support 10 near frame 1. A film 14 covers the inner edge of frame 1. For details, please refer to [link to specific structure]. Figure 1 As shown.

[0030] Thus, when the frame 1 is set on the inner edge of the precast component, such as a large tubular precast component or a water pipe structure for curing, the spray frame 30 moves along the guide rail 20 to spray the inner edge of the precast component. A cavity is formed between the film 14 on the frame 1 and the inner edge of the tubular precast component. Depending on the actual situation, curtains (not shown) can be set at both ends of the cavity to form a sealed cavity and improve the moisture retention and heat preservation effect. On the other hand, water receiving tanks 15 are also set at the bottom of the two sides of the frame 1 near the film 14. Water can be introduced into the water receiving tanks 15 through the film 14 to recover part of the sprayed water and achieve recycling.

[0031] In another embodiment of this utility model, brackets 10 are installed on the inner edges of both sides of the frame 1, a film 14 covers the frame 1, and the prefabricated components are inside the frame 1. Curtains (not shown) are provided on both sides of the frame 1, which can be self-adhesive or hooked and installed on the frame 1. The installation method is a common fixing method, so it will not be described in detail here. Please refer to the specific structure. Figure 3 As shown.

[0032] Specifically, the spray frame 30 of this utility model includes two main frame tubes 32 and a support tube 33. The two main frame tubes 32 are arranged in parallel and connected by the support tube 33 to form a frame. The bottom of the main frame tubes 32 is provided with rollers 41 driven by a motor 42.

[0033] The main frame pipe 32 is preferably designed with an arc shape, covering the outer edge of the precast concrete component or set on the inner edge of the precast concrete component. Spray heads 31 are installed at intervals on the main frame pipe 32, and each spray head 31 is equipped with an independent PVC ball valve switch, which can realize independent opening and closing.

[0034] It is worth noting that this utility model also provides a retractable leveling support 11 at the bottom of the frame 1, and a self-locking wheel 12 at the bottom of the frame 1. When the whole frame needs to be transported, the height of the leveling support 11 can be adjusted so that it is lower than the self-locking wheel 12, and the self-locking wheel 12 can be opened to achieve the overall transport of the frame 1. When maintenance is carried out, the height of the leveling support 11 can be adjusted so that it is higher than the self-locking wheel 12, and the leveling support 11 can provide stable support for the frame 1 for maintenance.

[0035] This utility model discloses a heat-insulating and humidity-controlled curing device for precast concrete components. By forming a sealed space through a frame 1 and a membrane 14, it can achieve a certain degree of heat preservation and moisture retention, reducing temperature and moisture evaporation. At the same time, a guide rail 20 is set on the frame 1, and the roller 41 is controlled by a motor 42 to move, which drives the spray frame 30 to move along the guide rail 20, that is, along the length of the precast concrete component, to uniformly spray and cure the precast concrete component, ensuring uniform curing, thereby achieving the desired curing effect and improving the quality of the precast concrete component.

[0036] Finally, the method described in this application is merely a preferred embodiment and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
