[0002] U-beam is a commonly used structural beam form. Its cross-sectional shape is U-shaped. U-beam has high strength and rigidity. Due to its cross-sectional shape, U-beam has high strength and rigidity. It can withstand large loads and torques. It is suitable for structures that need to support large spans or carry weight. At the same time, it has light weight. Compared with some other forms of beams, the cross-sectional shape of U-beam makes its weight lighter, which helps to reduce the overall weight of the structure and reduce the requirements for the supporting structure, thereby saving materials and costs, and the construction is convenient. The structure of U-beam is relatively simple, and the construction process is relatively simple. It can be made through templates and is easy to install and build, which makes the construction process more efficient and saves time and human resources.

[0003] U-shaped beams are usually made by pouring concrete using formwork, but the temperature is relatively low during construction and maintenance in winter, and the concrete solidification time is long during the construction process, which may lead to problems such as low concrete strength and cracking. Summary of the invention

[0005] The technical solution includes a casting template and a U-shaped beam body cast inside the casting template. The casting template is in a U shape similar to the U-shaped beam body. The casting template consists of a bottom template, two side templates symmetrically fixedly installed on both sides of the bottom template, and two top templates respectively fixedly installed on the top of the side templates.

[0006] The U-shaped beam body comprises a bottom plate, two side plates symmetrically fixed on both sides of the bottom plate, and two top plates respectively fixed on the top ends of the side plates;

[0007] An electric heating plate is arranged on the inner side of the casting template.

[0008] The casting template is provided with a rock wool layer.

[0009] A polyurethane foam layer is arranged inside the casting template.

[0010] The side mold on each side is provided with a plurality of water injection holes evenly distributed along the length direction of the casting template.

[0017] In conjunction with the accompanying drawings, the utility model includes a casting template and a U-shaped beam body cast inside the casting template, the casting template is in a U shape similar to the U-shaped beam body, and the casting template consists of a bottom mold 1, two side molds 2 symmetrically fixedly installed on both sides of the bottom mold 1, and two top molds 3 respectively fixedly installed on the top of the side molds 2;

[0018] The U-shaped beam body comprises a bottom plate 4, two side plates 5 symmetrically fixed on both sides of the bottom plate 4, and two top plates 6 respectively fixed on the top ends of the side plates 5;

[0019] An electric heating plate 7 is provided inside the casting template for heating and controlling the temperature of the U-shaped beam.

[0020] The casting template is provided with a rock wool layer 8, which can slow down the temperature loss of the U-shaped beam and has a heat preservation effect.

[0021] A polyurethane foam layer 9 is arranged inside the casting template, which can slow down the temperature loss of the U-shaped beam and has a heat preservation effect.

[0022] The side formwork 2 on each side is provided with a plurality of water injection holes 10 evenly distributed along the length direction of the casting formwork, through which the U-shaped beam can be humidified during maintenance; the water injection holes 10 penetrate the electric heating plate 7, the rock wool layer 8, the polyurethane foam layer 9 and other layers of the structure. In short, the inner end of the water injection hole 10 is in direct contact with the U-shaped beam.

[0023] A temperature and humidity monitor 11 is arranged outside the side form 2, and the detection end of the temperature and humidity monitor 11 passes through the casting formwork and is connected to the U-shaped beam body; the temperature and humidity monitor 11 is used to monitor the temperature and humidity of the U-shaped beam body during curing.

[0024] The working principle of the utility model is: when the U-shaped beam is cast in the casting template, the staff electrically connects the electric heating plate 7 to the external power supply through a connector. The electric heating plate 7 can increase the forming speed of the U-shaped beam under the low temperature transition in winter, and reduce the cracking of the U-shaped beam caused by low temperature. At the same time, the rock wool layer 8 and the polyurethane foam layer 9 inside the side mold 2 can reduce the heat loss during the heating process of the casting template, increase the thermal insulation effect of the casting template, and the staff can check the temperature and humidity of the U-shaped beam during molding and curing in real time through the temperature and humidity monitor 11 at one end of the side mold 2. When the humidity is too low, the external water pipe is connected through the water injection holes 10 evenly opened at the two ends of the side molds 2 to add water to the U-shaped beam inside the casting template, thereby increasing the humidity of the U-shaped beam and facilitating operation.

[0025] Compared with the prior art, the beneficial effects of the utility model are:

[0026] 1. When the U-shaped beam is cast in the casting template, the staff electrically connects the electric heating plate 7 to the external power supply through a connector. The electric heating plate 7 can increase the forming speed of the U-shaped beam in the low temperature state in winter and reduce the cracking of the U-shaped beam caused by low temperature. At the same time, the rock wool layer 8 and the polyurethane foam layer 9 inside the side mold 2 can reduce the heat loss of the casting template during the heating process, thereby increasing the thermal insulation effect of the casting template.

[0027] 2. The staff can check the temperature and humidity of the U-shaped beam during molding and curing in real time through the temperature and humidity monitor 11 at one end of the side mold 2. When the humidity is too low, the staff can connect the external water pipe through the water injection holes 10 evenly opened at both ends of the side mold 2 to add water to the U-shaped beam inside the casting template to increase the humidity of the U-shaped beam and facilitate operation.
