[0037] The following will describe in detail the specific implementation manners of the application of the present utility model with reference to the attached drawings. It should be understood that the specific implementation manners described herein are only used to illustrate and explain the present disclosure, and are not used to limit the present disclosure. In the technical solution disclosed in the application of the present utility model, unless otherwise stated, the orientation terms such as "upper, lower, left, and right" usually refer to those defined based on the drawing direction of the corresponding attached drawing, and "inner and outer" refer to the inner and outer relative to the contour of the component or structure itself. In addition, in the description with reference to the attached drawings, the same reference numerals in different attached drawings represent the same elements.
[0038] According to the present utility model application, a fixed formwork curing device is disclosed. As shown in Figure 1 、 Figure 2 , it includes: a steam curing shed 3 and a fixed formwork 5;
[0039] The outer surface of the steam curing shed 3 is covered and installed with a top heat insulation layer 1, and a bottom heat insulation layer 10 is laid on the ground inside the steam curing shed 3. A fixed formwork 5 for placing prefabricated components 4 is placed on the bottom heat insulation layer 10;
[0040] A hot air duct 7 is provided along the length direction below the fixed formwork 5. The hot air duct 7 includes duct walls 701 on both sides and a roof plate 702. The top of the duct wall 701 is covered and installed with the roof plate 702 to prevent hot air from directly blowing on the formwork. A distance d is maintained between the upper end surface of each roof plate 702 and the lower end surface of the fixed formwork 5; and heat dissipation structures are made on both the duct wall 701 and the roof plate 702;
[0041] A steam pipeline group 6 is arranged outside the duct wall 701.
[0042] In the above technical solution, a hot air duct 7 is provided below the fixed mold table 5 in the steam curing shed 3. Heat is transferred into the steam curing shed 3 through the hot air duct 7 to increase the temperature inside the steam curing shed 3. In this way, not only can the precast concrete member 4 be cured at a high temperature, but the uniformly distributed heat dissipation structure on the hot air duct 7 can also make the heat transfer and diffusion more uniform. And the fixed mold table 5 is not in full contact with the hot air duct 7, and a certain distance d is maintained between the upper end surface of the top plate 702 and the lower end surface of the fixed mold table 5, which is to make it more conducive to the uniform diffusion of hot air, so that the heat diffuses to the entire bottom space of the fixed mold table 5 and finally reaches the required temperature for curing.
[0043] Meanwhile, a steam pipeline group 6 is arranged in the steam curing shed 3 to perform high-temperature steam curing on the precast concrete member 4. On the one hand, it provides heat for the precast member 4, and on the other hand, the high-temperature steam also provides sufficient humidity guarantee in the steam curing shed 3 to prevent the concrete from being prone to cracks due to excessive water loss during hot air curing;
[0044] Finally, the entire outer surface of the steam curing shed 3 is wrapped with a top heat insulation layer 1. By using the heat insulation of the top heat insulation layer 1, the heat loss inside the steam curing shed 3 is reduced, achieving the effect of heat preservation for this curing device. This design scheme can not only improve the curing efficiency and cure the precast member 4 to the required strength for hoisting as soon as possible, but also reduce the consumption of thermal energy and achieve the purpose of saving energy consumption.
[0045] This technical solution solves the problems of ensuring the high-efficiency and high-quality curing of the precast concrete member 4 and the high energy consumption brought by high-temperature curing. And this device has a simple design, is convenient for operators to use, can be applied on a large scale, realizes the technical effect of high-efficiency and high-quality curing of the precast concrete member 4, saves energy consumption at the same time, and finally achieves the purpose of maximizing production capacity and economic benefits.
[0046] In this embodiment, as Figure 3 shown, the air duct wall 701 is formed by interlacing and laying two layers of bricks, the upper and the lower. The heat dissipation structure includes the gap G1 reserved between adjacent bricks on the left and right. Among them, the bricks are cement bricks with a high porosity, which is conducive to heat storage. The gap G1 between the bricks ensures the uniformity of heat dissipation to both sides. The design of this heat dissipation structure increases the heat dissipation area and ensures the uniformity of heat dissipation, which is conducive to improving the curing effect. Regarding the specifications of the gap G1, specifically: in the area about 4 meters away from the air inlet of the hot air duct 7, the gap G1 is 5 to 10 millimeters; in the middle 4-meter part, the gap G1 is 10 to 15 millimeters; in the remaining area at the far end of the mold table, the gap G1 is 15 to 25 millimeters.
[0047] In this embodiment, as Figure 3As shown, the heat dissipation structure includes a gap G2 reserved between two adjacent top plates 702. This design ensures uniform heat dissipation and better curing effect. Specifically: The top plate 702 at the air inlet of the hot air duct 7 is usually a concrete plate to avoid heat damage to the components above the mold table, while the top plates 702 in other sections are usually made of galvanized steel plates. The galvanized steel plates themselves have strong heat conduction ability, which can further promote the heat transfer of the hot air duct 7 to the fixed mold table 5 and the precast components 4. The gap G2 is generally controlled between 4 and 5 centimeters, which is convenient for ensuring uniform heat dissipation to the top while allowing heat diffusion and transfer.
[0048] In this embodiment, as Figure 4 shown, the steam pipe group 6 includes at least one steam branch pipe 601 arranged along the length direction of the fixed mold table 5, and a number of steam holes 601a are evenly spaced on each steam branch pipe 601. Usually, two steam branch pipes 601 are arranged on both sides of the hot air duct 7, and the steam branch pipes 601 are all located below the fixed mold table 5. This design further increases the heat dissipation area and ensures the uniformity of steam diffusion, which is beneficial to improving the steam curing effect.
[0049] In this embodiment, as Figure 1 shown, at least one layer of bubble film 2 is installed between the steam curing shed 3 and the top insulation layer 1. Utilizing the heat preservation characteristics of the bubble film 2, heat loss can be reduced, and the airtight heat preservation effect can be further improved. In a specific embodiment, it is generally advisable to install two layers of bubble film 2, which can basically better achieve the sealing and heat preservation of the steam curing shed 3 and avoid waste caused by installing too many bubble films 2.
[0050] In this embodiment, both the top insulation layer 1 and the bottom insulation layer 10 are made of insulation films.
[0051] In this embodiment, as Figure 1 shown, the insulation film is a metal reflective insulation film. The metal reflective insulation film is selected because the reflective insulation film adopts the working principle of reflective heat insulation, and the temperature of the film itself does not rise, so the heat insulation effect is better and more lasting, and it is also safer. In some specific embodiments, an aluminum foil heat insulation reflective film will be selected because compared with precious metals such as gold, silver, titanium, nickel, and indium, metal aluminum has a lower price and higher cost performance.
[0052] In this embodiment, as Figure 1 shown, heat preservation mortar 8 is laid on the surface of the metal reflective insulation film in the hot air duct 7. This design is to prevent the metal reflective insulation film at the bottom of the hot air duct 7 from being damaged due to the high temperature of the hot air.
[0053] In this embodiment, as Figure 2As shown, the distance d between the upper end surface of the top plate 702 and the lower end surface of the fixed mold table 5 is 10 to 15 cm. This distance range can not only ensure heat transfer to the fixed mold table 5 but also ensure better uniform diffusion of hot air and its heat to the surroundings.
[0054] The use steps of this fixed mold table curing device are described exemplarily in this utility model application as follows:
[0055] S1. The precast member 4 to be cured is located on the fixed mold table 5. The steam branch pipes 601 are installed on both sides below the fixed mold table 5, and a gap G2 is maintained between every two adjacent top plates 702.
[0056] S2. To ensure safety, the operators first evacuate completely outside the steam curing shed 3, and then two layers of bubble films 2 and metal reflective heat insulation films are successively installed and covered on the outer surface of the steam curing shed 3.
[0057] S3. Turn on the hot air blower to introduce hot air into the hot air duct 7 and open the high-temperature steam valve to introduce high-temperature steam into the steam branch pipes 601 to cure the precast member 4.
[0058] S4. When the precast member 4 is cured to the strength required for hoisting, turn off the hot air blower and the high-temperature steam valve to stop the steam curing.
[0059] S5. After the temperature of the precast member 4 drops to a suitable temperature, move it out of the steam curing shed 3.
[0060] The preferred embodiments of this utility model application have been described in detail above in conjunction with the drawings. However, this application is not limited to the specific details in the above embodiments. Within the scope of the disclosed technical concept, various simple modifications can be made to the technical solutions of this utility model application, and these simple modifications all fall within the protection scope of the patent of this application.
[0061] In addition, it should be noted that in the various specific technical features described in the above specific embodiments, they can be combined in any suitable way without conflict. To avoid unnecessary repetition, this application does not explain various possible combination methods separately.
[0062] Furthermore, any combination can be made between various different embodiments of this utility model application as long as it does not violate the idea of this disclosure, and it should also be regarded as the content disclosed in this utility model application.
