[0027] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are for illustrative purposes only and are not intended to limit the scope of this utility model. The utility model is described in more detail below by way of example with reference to the accompanying drawings. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.
[0028] Please see Figure 1-6 A movable steam curing and insulation shed for precast highway beams includes a top arc beam 8, a crossbeam 10 fixed to the bottom end of the top arc beam 8, a support column 2 fixed to the bottom end of the crossbeam 10, and casters 3 fixed to the bottom end of the support column 2. The casters 3 are rolled and supported inside a travel track 13, which is fixed parallel to the mounting base. Scissor braces 5 are provided between adjacent support columns 2. The top end of the scissor braces 5 is hinged to the support column 2 by a fixing bolt rod 7, and the bottom end of the scissor braces 5 is slidably installed on the support column 2 by an adjustable bolt rod 6. Double doors 4 are provided at the front and rear of the curing and insulation shed. The entire curing and insulation shed is covered with a rainproof cloth 14, and a steam curing system is installed inside. The aforementioned steam curing and insulation shed can solve technical problems such as rapid moisture evaporation and uneven coverage in low winter temperatures, difficulty in meeting constant temperature and humidity conditions, long production cycle of precast beams, high material consumption, high installation costs, fixed structure, poor mobility and difficulty in reuse, and difficulty in dismantling and recycling, as well as poor environmental protection of conventional steel structure insulation sheds.
[0029] In practical use, when precast beams need to be cured, the curing and insulation shed of this utility model is set up outside the precast beam. Then, steam is continuously introduced into the curing and insulation shed through a steam curing system to maintain a suitable temperature inside the shed, thereby ensuring the best curing effect. After curing is completed, the curing and insulation shed can be stored away.
[0030] Furthermore, multiple sets of vertical beams 9 are fixed between the top arc beam 8 and the crossbeam 10 at intervals. These multiple sets of vertical beams 9 effectively enhance the structural strength and stability between the top arc beam 8 and the crossbeam 10.
[0031] Furthermore, the casters 3 are fixed to the bottom of the support column 2 via wheel frames; the casters 3 are made of nylon. The use of the casters 3 facilitates the overall movement of the entire curing and insulation shed, thereby enhancing its flexibility of use. In addition, the use of nylon wheels provides wear resistance.
[0032] Furthermore, a diagonal brace 1 is fixed between the crossbeam 10 and the support column 2. The diagonal brace 1 enhances the structural strength and stability between the crossbeam 10 and the support column 2.
[0033] Furthermore, the ends of the fixed bolt rod 7 and the adjustable bolt rod 6 are provided with baffles and limiting nuts. Through the cooperation between the fixed bolt rod 7 and the adjustable bolt rod 6, the scissor brace 5 can be folded, thereby allowing the frame structure of the curing and insulation shed to be stored away when not in use, reducing the space it occupies.
[0034] Furthermore, the top arc beam 8, crossbeam 10, support column 2, and diagonal brace 1 are all made of round steel pipe. By using the aforementioned round steel pipe material, both structural strength and structural stability are ensured.
[0035] Furthermore, the steam curing system includes a steam hose 15 installed inside the curing and insulation shed. Multiple steam generators 12 are mounted on the steam hose 15, and the end of the steam hose 15 is connected to a boiler via a steam delivery pipe 16. This steam curing system provides steam to the entire curing and insulation shed during the curing process. During operation, steam generated by the boiler is delivered to the steam hose 15 via the steam delivery pipe 16, and then to the steam generators 12 via the steam hose 15. The steam generators 12 spray the steam in a mist, thereby achieving the purpose of curing the precast beams inside.
[0036] Furthermore, the steam generating device 12 uses a galvanized round pipe with evenly drilled holes in its upper part. Steam is evenly introduced into the curing and insulation shed through the steam generating device using a boiler and conveying pipe to ensure that the strength of the precast beam is rapidly improved.
[0037] Furthermore, the rainproof cloth 14 is made of weather-resistant material. The use of this weather-resistant material significantly enhances the thermal insulation effect of the precast beam concrete, reducing the risk of cracking due to temperature changes.
[0038] Furthermore, the gate 4 is made from scrap iron cut on-site; this significantly enhances the thermal insulation effect of the precast beam concrete and reduces the risk of cracks in the precast beam concrete due to temperature changes.
[0039] Furthermore, the travel track 13 is made of channel steel. Using channel steel facilitates the movement and limiting of the casters 3.
[0040] Furthermore, the temperature inside the curing shed is controlled at 40-50℃ by the steam curing system. This temperature ensures optimal curing results. During the curing process, steam is generated by a boiler and delivery pipes and introduced into the curing shed through a steam generator, ensuring uniform steam distribution throughout the precast beams, guaranteeing the quality and strength of the precast concrete, and improving construction efficiency.
[0041] Furthermore, the maintenance and insulation shed can adjust its coverage area according to needs, and does not take up space when it is retracted, making it suitable for quick construction in different scenarios.
[0042] The working process and principle of this utility model:
[0043] The curing and insulation shed is moved to the planned site, and a steam generator is installed inside. The cast-in-place precast beams are transferred to the shed via a mobile platform. The front and rear doors are closed to ensure the entire shed is fully enclosed. Steam is then introduced into the shed through a boiler and pipelines via the steam generator, ensuring the precast beams are fully enveloped in steam. Once the concrete reaches its design strength, the beams can be moved to the next stage. Using a mobile steam curing and insulation shed for highway precast beams helps improve the quality of the precast concrete molding. By providing a constant temperature and humidity environment, it significantly shortens the time it takes for the precast beams to reach their design strength, thereby improving construction efficiency.
