Double parallel radiant tube wall prefabricated laminated board and its forming method

Abstract

The invention provides a double-parallel radiant tube wall prefabricated laminated board and a forming method thereof. The double-parallel radiant tube wall prefabricated laminated slab comprises an integrally cast reinforced layer (1), a radiant tube (2) and a concrete layer (3), and the radiant tube (2) is located close to the reinforced layer (1). On one side of the room, the concrete layer (3) is covered outside the reinforcement layer (1) and the concrete layer (3), and the radiant tubes (2) are arranged in a double parallel structure. According to the double parallel radiant tube wall prefabricated laminated plate of the present invention, the structure is simple, the heat transfer efficiency is high and the forming efficiency is high.

Description

technical field [0001] The invention relates to the technical field of building heating energy utilization, in particular to a double-parallel radiant tube wall prefabricated laminated board 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 winter ...

Problems solved by technology

[0004] However, since the radiant tube 2' is arranged between the upper and lower layers of steel mesh, and the upper and lower sides of the steel bar layer 1' are covered with concrete, the heat of the radiant tube 2' radiates from the lower concrete to the indoor distance is relatively large. It 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 upper and lower 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 upper and lower layers of steel mesh, and the steel mesh is poured together with the concrete layer 3', when the radiant tube 2' has a problem and needs to be replaced, the steel mesh must be removed before it can be repaired. The operation of replacing and maintaining the radiant tube 2' 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 production is difficult to achieve industrialization due to the long molding cycle
