Description

Technical Field

[0001] The present invention relates to the technical field of semiconductor chip processing, in particular to a novel energy-saving and environment-friendly secondary structure building wall and a preparation process thereof. Background Art

[0002] The use of cast-in-place concrete walls in the construction industry is a construction method with many advantages. However, the most difficult problem to avoid with this type of cast wall is that cracks are prone to occur in the wall, which poses a great safety hazard. To this end, technicians in this field have provided a variety of solutions to solve the problem of wall cracks, such as: using steel bars to be distributed in a horizontal and vertical spacing arrangement, and then using hollow thin-walled tubes to limit steel bars, and finally supporting wall formwork, and then casting concrete, curing, and demolding to form a wall; another type of construction method is to use non-net polystyrene boards, tie external steel bars, and then set up molds, cast concrete, curing, demolding, applying anti-cracking mortar, and scraping putty to form a wall in order to avoid the problems of excessively fast hydration heat temperature rise and fall of concrete during the solidification process, and water loss and shrinkage of the concrete surface. Although these methods can solve the problem of cracks in cast-in-place concrete walls and improve the safety of the walls, the shortcomings of these methods are that they all require the use of template casting and wall plastering processes, which are complex to construct, have a long construction period, and high construction costs. The existing ones also use steel frame structures, but when in use, the internal steel frame is generally a whole piece of I-beam or rectangular steel pipe, which makes many thermal bridges between the inside and outside of the wall, thus affecting the thermal insulation function.
