Description

Door and window steel auxiliary frame integrally constructed with main body structure and application method thereof Technical Field The invention relates to the technical field of constructional engineering, in particular to a steel auxiliary frame for constructing doors and windows integrally with a main body structure and a use method thereof. Background Along with the continuous development of the building industry, the building quality requirement is continuously improved, and the aspects of building construction standardization, construction efficiency, construction cost control and the like are also continuously improved. However, in the existing building door and window installation process, the outer frame is installed after the hole is reserved, and then the procedures of closing up the peripheral gaps of the door and window, assembling the door and window sashes and the like are carried out. The installation mode is that whether the door and window is replaced or maintained, a great amount of work is required, and particularly when the door and window is replaced, the door and window frame is required to be replaced after the original gap filling block is opened when the wall body of the opening is opened, the working procedure is laborious and time-consuming, the wall body structure is greatly damaged, and potential safety hazards are left for the use of the building wall body. In addition, because the reservation of entrance to a cave receives the influence of many factors such as building templates, concrete placement, brickwork construction and the like and can not once only be under construction in place when civil engineering is under construction, need repair the adjustment through artifical later stage plastering, the engineering volume increases, and the construction benefit is low, and because need to carry out the crack to door and window opening periphery and arouse the problem such as seepage easily. The traditional method for solving the problems is that a steel auxiliary frame is additionally arranged outside a door and window, the steel auxiliary frame is installed after the construction of concrete and masonry is completed, a gap between the steel auxiliary frame and the masonry is filled with waterproof mortar before plastering inside and outside, and the door and window is installed after the construction of civil engineering such as inner and outer coating is completed. Thus, the waterproof quality of the door and window is ensured, and the damage and pollution of the door and window caused by civil engineering are avoided. But the addition of the steel subframe brings new problems. The conventional installation method of the steel auxiliary frame comprises the steps of firstly temporarily fixing the steel auxiliary frame by using a wooden wedge, then fixing the steel auxiliary frame on a concrete wall body by using a metal expansion bolt, tightly filling gaps between the steel auxiliary frame and the masonry body by using dry and hard cement mortar, smearing round corners at the internal corners of the periphery, collecting waterproof mortar into an eight-shaped opening, taking out the temporarily fixed wooden wedge after the mortar reaches a certain strength, and tightly filling the gaps by using the dry and hard cement mortar. The construction process is complex and is greatly influenced by human factors. Because the lower part of the steel auxiliary frame is a main channel for rainwater leakage, the quality of the sealing quality of the part of waterproof mortar directly influences the waterproof effect, and the risks of hollowing, cracking, water leakage and the like of plastering can occur in secondary plastering closing-in and seam plugging around the door and window frame. The mortar can pollute and corrode doors and windows when plastering and edging, and the later maintenance cost is increased. In the house plate, because the aluminum alloy template has the characteristics of flexible disassembly and assembly, high rigidity, long service life, high precision, smooth and clean poured cement, low mechanical dependency degree of construction and the like, the aluminum alloy template has been widely applied to replace wood templates. In the design concept of the house mature at the present stage, the periphery of the door and window opening is basically optimized into a full-concrete structure. Therefore, the traditional positioning and mounting method of the door and window steel auxiliary frame cannot meet the current technical requirements, and how to improve the mounting strength of the door and window steel auxiliary frame and strengthen the waterproof effect, and optimize the mounting process at the same time becomes a problem to be solved in the field. Disclosure of Invention The invention aims to overcome the defects of the prior art, and provides a steel auxiliary frame for integrally constructing doors and windows with a main structure, which comprises a steel
