[0019] Example, refer to Figure 1 - Figure 2 A provided technical solution: A precast beam mobile steam curing shed, including a T-beam production pedestal 101, with a steam curing shed 1 arranged outside the T-beam production pedestal 101. The inner wall of the steam curing shed 1 is fixedly connected with a steam pipeline 2, and the steam pipeline 2 is connected to a steam inlet 3 extending from the side wall of the steam curing shed 1; a generator 4 is fixedly installed on the side of the steam curing shed 1, a travel controller 401 is fixedly connected to the top side end of the generator 4, the bottom of the steam curing shed 1 is movably connected with a rail 5, a travel motor 6 is arranged on the rail 5, and the travel motor 6 is connected to the steam curing shed 1 through a connecting seat 601; it also includes a bottom plate 7, a boiler 701 is fixedly arranged on the top surface of the bottom plate 7, a support 8 is fixedly connected to the side end of the top surface of the bottom plate 7, and a monitoring screen 801 is fixedly installed at the end of the support 8.

[0020] Among them, the boiler 701 is a steam boiler, and biomass compressed particles processed from straw, rice husks, peanut shells and forestry waste are used as the combustion energy. Using this fuel has the advantages of convenient transportation and storage, high combustion energy, no pollution, and the burned ash powder can be used as organic fertilizer for greening construction; the rail 5 uses 5*3 cm channel steel as the mobile rail, so that the steam curing shed can move longitudinally along the rail in the beam yard and cover multiple T-beam production pedestals; during use, the steam inlet 3 is connected to the air outlet of the boiler 701, and the steam generated by the steam boiler is introduced into the steam curing shed 1.

[0021] The steam curing shed 1 is made of rock wool sandwich color steel plate, and there are large doors that open and close left and right at the front and rear ends. Among them, the steam curing shed 1 made of rock wool sandwich color steel plate has good heat insulation performance, and can lock the steam temperature and humidity inside the steam curing shed 1. The structure of the large door is the same as that of the door of the existing container, and this conventional structure is omitted in the drawings; when the steam curing shed 1 travels, the large door is opened, and after the T-beam production pedestal 101 is loaded, the large door is closed for steam curing.

[0022] The steam pipeline 2 is arranged in a "hui" character shape on the inner wall of the steam curing shed 1. The bottom of the horizontally arranged steam pipeline 2 is supported on the inner wall of the steam curing shed 1 by a number of bases 201. Among them, the base 201 is used to install and support the steam pipeline 2; the "hui" character shape arrangement makes the steam discharged from the steam pipeline 2 more uniform in the steam curing shed 1, the humidity and temperature are more uniform everywhere, and the steam can fill the entire steam curing shed.

[0023] Eight groups of corresponding electric drive rollers are respectively arranged on both sides of the steam curing shed 1; the generator 4 is a diesel generator 4, and the diesel generator 4 generates electricity to start the traveling motor 6, and the steam curing shed 1 moves on the track 5 by using the electric drive rollers. Among them, the diesel generator 4 serves as the power source of the steam curing shed 1.

[0024] The steam pipeline 2 is made of galvanized steel pipe, and a number of steam holes are arranged on the steam pipeline 2; the steam inlet 3 arranged on the side of the steam curing shed 1 accesses the steam generated by the steam boiler 701 into the steam curing shed 1 through the steam holes on the steam pipeline 2.

[0025] Temperature and humidity sensing devices are installed at multiple points in the steam curing shed 1. Among them, the temperature and humidity sensing devices cooperate with the monitoring screen 801 to realize the real-time monitoring of various indicators in the steam curing shed 1 by using existing technologies, which is convenient for adjusting the operation state of the boiler 701, controlling the curing time, adjusting the operation state of the steam generating equipment through the monitored data, realizing dynamic control, ensuring the curing conditions while reducing energy consumption.

[0026] The lower part of the steam curing shed 1 is sealed with rubber strips at the feet to avoid the loss of steam in the steam curing shed 1.

[0027] Specific implementation method: The preferred application scenario of the above-mentioned steam curing shed is in the beam yard where the T-beam production pedestals 101 are arranged in a row. There are 4-6 T-beam production pedestals 101 in a row. One such steam curing shed is arranged on a row of T-beam production pedestals 101, and this steam curing shed can move back and forth on the track 5, so that the pedestals on a row of T-beam production pedestals 101 can share one shed, greatly reducing the cost.

[0028] The construction process is as follows: Install the track 5 on both sides of the T-beam production pedestal 101; then install the steam curing shed 1, the internal steam pipeline 2, the boiler 701, etc.; then complete the precast beam production and concrete pouring on the T-beam production pedestal 101; manually operate the traveling controller 401 to move the steam curing shed 1 above the beam body. After moving in place, use the gantry crane to lift the boiler 701 as a whole ( Figure 2Lift it to a nearby location; connect the boiler 701 to the steam inlet 3, and close the door of the steam curing shed 1; add fuel and water to the boiler 701, start generating steam, and the steam enters the steam curing shed 1 through the steam inlet 3 and the steam pipeline 2 and is released from the holes. After the steam water condenses and falls to the ground, it enters the drainage system of the beam yard itself. During the process, the temperature inside the shed is monitored through the temperature sensor in the shed, and the concrete specimens are cured together with the precast beams. After 20 hours, the concrete specimens are taken out and sent to the laboratory for a pressure test. If the precast beams reach the tensile strength according to the test results of the concrete specimens, open the door to release the steam and disconnect the steam pipeline from the boiler 701. After that, move the steam curing shed 1 to the next T-beam production pedestal 101 and repeat the operation. It should be noted that the gantry crane is provided by the beam yard itself; the whole boiler 701 ( Figure 1 ), and the steam curing shed 1 ( Figure 2 ), after separation, the boiler 701 does not need to move synchronously with the steam curing shed 1 (reducing the power requirement for moving the steam curing shed 1), and the boiler 701 can be moved to a suitable location in the beam yard by the gantry crane to supply steam to multiple steam curing sheds 1 at the same time.

[0029] In winter, it takes 4 days for conventional precast T-beams to reach the tensile strength; after the above technology is actually applied, it can ensure that the tensile strength is reached within 20 hours, greatly improving the production speed of the beam yard.

[0030] Although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
