Description

Structure for blocking heat transfer through curtain wall building thermal cooling bridge and construction method thereof

Technical field

The invention relates to a structure for blocking heat transfer in a building, in particular to a structure for blocking heat transfer through a curtain wall building thermal cooling bridge and a construction method of the structure.

Background technique

Generally speaking, the treatment method of the curtain wall building thermal cooling bridge is to provide a heat-dissipating cold bridge material with a thermal conductivity of about 0.25 W/(m·K) between the outdoor metal member and the indoor metal member, and the heat-breaking cold bridge material It is often placed on the outside of the indoor metal member or on the inside of the outdoor metal member. This is to keep the insulation isotherm in a straight line as much as possible, and keep the lower temperature line outside the indoor metal member to obtain the best heat insulation. Cold bridge effect. However, due to various reasons in the actual project, some curtain wall buildings failed to provide thermal insulation bridge materials between indoor metal components and outdoor metal components, or even if thermal insulation cold bridge materials were provided, satisfactory insulation was not achieved. The effect is that if the insulation performance of these curtain wall buildings is to be improved or modified, it is necessary to partially or even completely dismantle the entire curtain wall, which is difficult and economical.

A super high-rise curtain wall project in the CBD area of Beijing. Since the completion of the project in 2007, there has been a continuous occurrence of condensation and icing in the room due to the cold and hot bridge of the curtain wall aluminum frame. At the same time, due to the large amount of heat passing through the curtain wall, the cold and hot bridge is lost. Increased air conditioning load and wasted electricity bills. Since the completion of the project in 2007, Party A has been very distressed by the indoor condensation and the curtain wall is not insulated, and also tried to remedy, including the use of thermal imaging cameras by third parties to determine the location of the hot and cold bridges of the curtain wall, but always seek no To any effective method of solving a hot and cold bridge on an existing curtain wall.

From the perspective of engineering design, it is conceivable to cover the location of the hot and cold bridge with thermal insulation materials such as mineral wool, or to select a higher-profile glass to meet the requirements of building energy conservation, but both technical solutions have deficiencies:

Technical solutions for similar coatings using thermal insulation materials such as mineral wool:

1) In order to achieve the energy-saving design goal of the curtain wall and prevent condensation on the curtain wall, the thickness of the thermal insulation material such as mineral wool is at least 2.5cm, and the thickness of the finished metal keel after the coating is completed is increased by at least 5cm, which seriously affects the appearance and Indoor lighting area will also reduce indoor space and use area, and need to add more interior decorative board materials;

2) The compressive performance of thermal insulation materials such as mineral wool is not satisfactory, and the surface of the indoor metal keel after coating is not easy to maintain flat;

3) The processing property of mineral wool and other thermal insulation materials is poor, and it is difficult to accurately cut the cut length, and it is difficult to make complex shapes such as L shape;

4) The fixing method of mineral wool insulation material is usually the method of planting nails, etc., which is difficult to implement on indoor metal keels.

Insufficient technical solutions for the use of higher-profile glass:

1) The so-called higher-profile glass is actually a lower heat transfer coefficient of glass. At present, single-silver or double-silver low-e insulating glass has been widely used in engineering. The improvement of glass configuration has the following ways: improving the performance of low-e film (such as three-silver low-e) and increasing the thickness or quantity of hollow layer (such as Three glass double insulating glass), using vacuum glass and the like. In these schemes, although the heat transfer coefficient of the glass is reduced, in the average heat transfer coefficient of the curtain wall, the heat transfer coefficient ratio of the glass is often less than 50%, so the efficiency is not very satisfactory.

2) Whether it is a curtain wall building or a new curtain wall building, the use of a higher-profile glass will greatly increase the cost of the entire curtain wall, especially for existing curtain wall buildings. Changing the glass configuration means that the existing glass needs to be removed, and Replacing new glass will be a technically complex and costly project.

The applicant has obtained the patented Chinese utility model patent 2015209456306, “Structuring the structure of heat transfer through the thermal cooling bridge of the curtain wall building node”, the technical solution is between the indoor metal keel and the curtain wall or the outdoor metal keel or metal component. Fixing an integral heat-insulating strip made of aerogel insulation blanket close to the outside, without changing the design of the keel profile used in the existing curtain wall, greatly improving the insulation performance of the curtain wall and ensuring no condensation in the curtain wall interior The problem, but for the large number of curtain wall buildings that have been built and are being used, due to the large amount of heat transfer in the indoor metal keel, the condensation and icing in the curtain wall construction room in winter, the problem of hot summer heat, the patent does not give a change. Any feasible technical solution with structure.
