Existing building reinforcement, self-supporting and thermal insulation integrated system and construction method

Abstract

The invention discloses an existing building reinforcing self-supporting thermal insulation integrated system, belongs to the field of buildings. The system comprises a frame-type reinforcing structure and a thermal insulation wall plate, characterized in that the frame-type reinforcing structure comprises vertical reinforcing steel angles fixed at an outer wall corner portion surrounding the existing building, vertical reinforcing type steel columns fixed at an outer wall of the existing building and located at a junction of vertical and horizontal walls, and horizontally connecting slab ribs disposed at a floor layer of the outer wall of the existing building and connecting the vertical reinforcing steel angles and the vertical reinforcing type steel column to form a filling unit frame; and the thermal insulation wall plate is arranged in the filling unit frame. The invention further provides a construction method for the system. The existing building reinforcing self-supporting thermal insulation integrated system and the construction method provided by the invention have the beneficial technical effects that the system reinforces the existing building; moreover, mounting the thermal insulation wall plate in the reinforcing structure to implement a self-supporting body of the thermal insulation wall plate reinforces the current building, and the thermal insulation wall plate does not add any load to the existing building, either, which achieves reinforcing and self-supporting thermal insulation integration, and the thermal insulation effect can reach 60%-75% without generating a cold bridge.

Description

technical field [0001] The invention belongs to the field of construction, and in particular relates to an existing building reinforcement, self-supporting and thermal insulation integrated system and construction method for energy-saving renovation of existing building exterior walls and integration with existing building reinforcement. Background technique [0002] At present, the total amount of existing buildings in my country is about 50 billion square meters, of which urban housing is about 27 billion square meters, and public buildings and industrial buildings are about 23 billion square meters. About 5 billion to 10 billion square meters of residential buildings have been implemented according to the 50% energy-saving standard, and about 17 billion to 20 billion square meters need to be renovated. According to statistical analysis, building operation energy consumption accounts for about 25% of the country's total energy consumption, and the adverse effects of high e...

Problems solved by technology

However, the two current transformation methods have their own shortcomings.

The disadvantages of the method of pasting polystyrene and plastering mortar are low reliability, easy to crack and fall off, and cause accidents; second, the service life is short, and most of the adhesives are chemical products, and the service life is less than 20 years; third, most of the existing buildings are old buildings , the weight when pasting the insulation will inevitably affect the reliability of the building; Fourth, the workload on site is heavy, and there are relatively large safety hazards

The disadvantage of the external insulation material method is that the cost is high; the second is that it is easy to produce cold bridges

There is no doubt that the above-mentioned methods will cause additional loads on existing buildings, and energy-saving renovations are mostly aimed at old buildings. Since 1949, my country has had two construction climax periods. The first climax period It was in the 1950s, the architectural design and construction standards were low, and the quality was poor. Now it is aging and seriously damaged, and urgently needs to be repaired and strengthened.
