Ceiling structure with bottom-mounted concentric square radiation pipe and construction method of ceiling structure

Abstract

The invention provides a ceiling structure with a bottom-mounted concentric square radiation pipe and a construction method of the ceiling structure. The ceiling structure with the bottom-mounted concentric square radiation pipe comprises a steel bar layer (1), the radiation pipe (2) and a concrete layer (3), wherein the radiation pipe (2) is positioned at the lower side of the steel bar layer (1); the concrete layer (3) covers the outside of the steel bar layer (1) and the outside of the radiation pipe (2); and the radiation pipe (2) is of a concentric square structure. The ceiling structure with the bottom-mounted concentric square radiation pipe according to the invention has the advantages of simple structure, low repair difficulty, high heat transfer efficiency and low cost.

Description

technical field [0001] The invention relates to the technical field of building heating energy utilization, in particular to a back-shaped radiant tube lower-mounted ceiling structure and a construction 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 an...

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
