Energy-saving thermal-insulation reinforced concrete frame and preparation method thereof

Abstract

The invention relates to an energy-saving heat-preservation reinforced concrete frame and a preparation method thereof. The preparation method comprises the steps of preparation of a main body heat-preservation concrete structure frame, preparation of a self-heat-preservation layer, preparation of self-heat-preservation building blocks, preparation of a fireproof sound-insulation composite board, preparation of the energy-saving heat-preservation reinforced concrete frame and the like. The invention has the following beneficial effects: through combination of the fireproof sound insulation composite board and the self-insulation building block, the integrity and weather resistance of the building insulation wall are solved, and the insulation layer does not fall off; no cold bridge phenomenon exists; no surface cracking phenomenon exists; the surface external force damage resistance is high; the service life of the wall thermal insulation system is really the same as that of a building; even if the fireproof sound insulation composite board falls off, a certain heat insulation effect can be maintained through the self-heat-insulation building block, so that the internal and external temperatures of the building are effectively isolated, the energy consumption for heat insulation or refrigeration in the building is reduced, and the building is more energy-saving and environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of building material preparation, and in particular relates to an energy-saving and heat-retaining reinforced concrete frame and a preparation method thereof. Background technique [0002] In construction engineering, since building energy consumption accounts for more than 40% of all energy consumption, building energy conservation is a long-term development strategy. At present, there are four methods for exterior walls: exterior wall insulation, exterior wall interior insulation, sandwich walls, and concrete self-insulation block masonry. External insulation of external walls is the mainstream method advocated now. It has the advantages of eliminating thermal bridges, increasing the usable area, and protecting the main structure. The disadvantages are that the construction technology is difficult, the process is many, the construction period is long, the labor investment is large, and the operator's skill...

AI Technical Summary

Problems solved by technology

External insulation of external walls is the mainstream method advocated now. It has the advantages of eliminating thermal bridges, increasing the usable area, and protecting the main structure. The disadvantages are that the construction technology is difficult, the process is many, the construction period is long, the labor investment is large, and the operator's skills are required. Higher, the shortage of labor is a major problem that will plague the development of the construction industry in the future. The price of labor has been rising, and in recent years, cracking and falling off of the outer surface of the outer wall have occurred from time to time, so its durability has always been a problem for the construction industry. The bottleneck of development; the advantages of internal insulation of external walls are convenient construction, good use environment of thermal insulation materials, and are not affected by harsh conditions such as ultraviolet rays, wind and rain, high temperature, freezing, etc. The disadvantages are that they cannot block thermal bridges, reduce the usable area of ​​houses, and are easy to decorate Destruction of the insulation layer, etc.; the advantage of the sandwich wall is that it has good thermal insulation performance, can block most of the thermal bridges, and is less expensive than external insulation, and the wall is not prone to cracks. The disadvantage is that the construction is difficult and the quality of the masonry is high. Long construction period; self-insulating block masonry is a recently developed structure, which uses high thermal resistance sandwich composite blocks to directly build external walls that meet the requirements, and the cost is high

[0003] Due to the large climate difference between the north and the south, most of the external wall insulation products have poor durability; the construction quality control management is difficult; the service life of the insulation layer is short; the maintenance of the insulation layer after the warranty period is difficult

[0004] In recent years, some areas in China have successively introduced a series of integrated building structure insulation technologies, such as composite insulation welded grid concrete shear wall technology, self-insulation block technology, etc., through practical application, some problems have also been exposed: (1) Cold The bridge phenomenon is obvious, and frost and condensation occur indoors after the project is put into use; (2) The construction process is complex, requiring high skills for operators, and professional equipment is required for construction; (3) The project cost is relatively high; (4) The external thermal insulation of external walls has fire hazards, which are caused by the current thin plaster external thermal insulation materials
