Description

Structure of bridge-cut-off heat insulation for constructional column

Technical Field

The utility model belongs to the field of masonry structures, and particularly relates to a construction column bridge-cut-off heat insulation structure.

Background

The building enclosure system is an important building component, and has the main functions of separating the space used in the building from the external outdoor environment and maintaining the indoor environment stable. The enclosure generally reduces heat exchange between the interior and exterior of the building by lightweight materials having low heat transfer coefficients. Some parts exist in the building enclosure structure, the heat transfer coefficient of the parts is larger than that of adjacent parts, and the parts are more likely to be bridges for transferring heat indoors and outdoors of the building, so the parts are called thermal bridges. In the thermal bridge area, the temperature of the indoor end of the thermal bridge is obviously higher than other parts in summer and is obviously lower than other parts in winter, condensation and frosting are extremely easy to occur, the durability of the local building components is reduced in the long term, and the normal use inside the building is influenced. Meanwhile, from the perspective of overall energy consumption of the building, under the condition of good thermal performance of the overall building, the thermal bridge can become an obvious indoor and outdoor heat transfer window, so that the overall heat preservation and insulation capacity of the building is reduced, and the energy consumption of the building is increased. The masonry structure is a simple and reliable building structure system, is widely applied to 1-2 layers of houses, particularly in the field of rural construction, has low construction cost and high construction speed, and is widely applied. The building block that present widely adopted is light high-strength heat preservation material, and coefficient of heat conductivity is lower, but the constructional column that exists in the brickwork structure is reinforced concrete column, and coefficient of heat conductivity is obviously higher than the brickwork structure, becomes the heat bridge in the brickwork structure extremely easily, causes indoor wall moldy to drop, reduces the whole comfort level of building indoor environment.

At present, the related technology of bridge-cut-off heat insulation is widely applied to the parts such as doors and windows, curtain walls, parapet walls and the like in the construction engineering, the thermal performance of the whole building is obviously improved, for example, in a reinforced concrete structure, the thermal bridge parts such as columns, beams, hollow floors, door and window openings and the like are all subjected to external heat insulation treatment by adopting heat insulation materials, but the external heat insulation treatment method is more suitable for the reinforced concrete frame structure, and for a single-layer and low-layer masonry structure, the building blocks have strong self-heat insulation performance, and the secondary waste is obviously caused by the external heat insulation treatment mode, so that the thermal bridge isolation treatment of the constructional columns in the masonry structure is a more economic and more convenient masonry structure thermal bridge treatment mode.
