Radiant tube metope prefabricated laminated slab and molding method thereof

Abstract

The invention provides a radiant tube metope prefabricated laminated slab and a molding method thereof. The radiant tube metope prefabricated laminated slab includes an integral casting molded steel bar layer (1), a radiant tube (2) and a concrete layer (3), the radiant tube (2) is located on one steel bar layer (1) close to the indoor, and the concrete layer (3) is coated outside the steel bar layer (1) and the concrete layer (3). According to the invention, the radiant tube metope prefabricated laminated slab has the advantages of simple structure, high heat transfer efficiency and high construction efficiency.

Description

technical field [0001] The invention relates to the technical field of building heating energy utilization, in particular to a prefabricated laminated panel on the wall surface of a radiant tube and a forming method thereof. Background technique [0002] With the rapid development of the domestic economy, people's awareness of energy saving and environmental protection is also increasing, and the requirements for high efficiency and energy saving of heating in buildings are also getting higher and higher. With the growing demand for this demand, the use of ceiling low-temperature radiant heating and cooling has become a high-comfort and low-energy heating and cooling method recognized by the world's engineering circles. In recent years, the heating and cooling method with high comfort and low energy consumption has gradually been adopted by some construction projects in my country's construction industry. Its characteristics are: 1. It can be described as dual-purpose in win...

Problems solved by technology

[0004] However, since the radiant tube 2' is arranged between the inner and outer layers of steel mesh, and the inner and outer sides of the steel bar 1' are covered with concrete, the heat of the radiant tube 2' radiates from the inner layer of concrete to the room for a relatively large distance. , will cause a large amount of heat loss in the radiant tube 2' in the concrete layer 3', and the heat transfer efficiency is not high

In addition, due to the need to leave enough space between the two layers of steel mesh to place the radiant tube 2', it will result in a large distance between the inner and outer two layers of steel mesh, making the overall thickness of the ceiling structure larger, resulting in material loss more, increased cost

Since the radiant tube 2' is set between the inner and outer layers of steel mesh, and the steel mesh is poured together with the concrete layer 3', when there is a problem with the radiant tube 2' and needs to be replaced, the inner layer of steel mesh must be removed. The operation of replacing and maintaining the radiant tube 2' can be performed, which makes the maintenance of the radiant tube 2' very inconvenient and the maintenance cost is very high

[0005] Since the ceiling structure is set on the top of the house, the heat emitted by the radiant tubes gradually diffuses from top to bottom in the room. As for the position of the window, the closer to the window, the greater the influence of the indoor temperature on the outdoor temperature, so that the closer the radiant tubes are to the other. The worse the temperature adjustment effect is at the position of the window, the greater the difference in indoor temperature distribution will be, which will affect the uniformity and comfort of indoor temperature distribution.

[0006] In addition, this kind of radiant tube ceiling structure mostly adopts cast-in-place slab structure, which can enhance the integrity and earthquake resistance of the house, has a large bearing capacity, and also has certain advantages in heat insulation, sound insulation, waterproof, etc. , but this kind of structure is time-consuming and labor-intensive, and the construction period is long and the production is difficult to realize industrialization
