[0005] However, if the productized complete set of doors and windows does not have a reasonable door and window frame support structure, it cannot solve the above three problems, which will inevitably lead to the following defects in the complete set of doors and windows:
[0006] 1. The size of the final product does not match the site, making it difficult to install or leaving too large seams; to a large extent, it depends on the technical level and experience of the workers to trim and adjust the processed wooden components on site, resulting in the product's use function and appearance standard At the same time, the quality of product installation varies from person to person and is uneven; due to the lack of precision measures and controllability on the construction site, hardware such as door locks and hinges can only be installed on site with holes, resulting in product damage or even destruction happens sometimes;
[0007] 2. Due to the lack of corresponding effective fastening technology to target the base of different materials, foaming fillers (or expansion glue) and pneumatic gun nails are usually used for product fastening. Once the foaming agent is aged or polluted, it is difficult to carry the doors and windows The impact and other loads of the door and window frames will cause many safety hazards such as loosening, deformation, cracking and even falling off of the door and window frames;
[0008] 3. Due to the lack of corresponding definition criteria and standards, the installation interface and operation process of complete sets of doors and windows overlap with decoration construction projects in a large number, which makes it difficult to guarantee the accuracy, surface appearance quality and installation progress of the products; at the same time, as a product purchase The client of the party often needs to communicate and coordinate continuously between the decoration construction party and the complete door installer. Not only is the process very cumbersome and the burden on the customer is increased, but also the phenomenon of wrangling and disputes is not uncommon.
[0009] None of the current national building standard design atlas "wooden doors and windows" (integrated parts) 03J601-2, "residential doors" 01SJ606, and the industry standard "building wooden doors and windows" JG / T122-2000 can solve the above three problems. A reasonable door and window frame support structure that avoids the above-mentioned defects. The wooden door and window frame structures shown in the above specifications are all split structures composed of veneers, cheese boards and other individual pieces through splicing and gluing. It is not formed as a whole, and the firmness of the door and window frame itself, the firmness of the installation of the door and window frame and the wall, and how to bear the gravity of the door and window and the impact of the door and window switch do not have a rigorous and reasonable force-bearing and rotating structure. The root cause of the above problems
[0010] Other door frame structures such as patents CN101273865 and CN101603397 are roughly the same as the above-mentioned structures. The firmness of the door frame itself and the fastening of the door frame and the wall are difficult to bear the gravity and impact load of the door leaf. The accuracy of matching, etc. cannot meet the requirements, and the above-mentioned defects still exist
[0011] The above-mentioned prior art cannot cope with the objective status quo of inaccurate dimensions and angles of reserved door and window openings in real projects, inconsistent wall materials, individualized differences in surrounding decorations, and insufficient preconditions for data definition. It is often far from the design expectation, and the uncertainties of various factors in the process have also led to vague responsibilities of the supply and demand parties and third-party functional departments, and disputes such as mutual evasion often occur
Therefore, the relevant safety hazards and social contradictions always exist, and it has become a major problem for relevant technical personnel. At the same time, it is impossible to establish standards and specifications for real product attributes that are different from the acceptance standards for engineering wooden doors and windows, which is not conducive to the relevant departments for the industry. Management and Supervision
[0012] However, with the progress of the times, the professional technologies of all walks of life are constantly being updated, and people's demand for finished doors and windows is also increasing. However, the core technology that can effectively improve the safety and convenience of the installation of finished door and window frames has not yet been solved.
For such problems affecting industrial upgrading and restricting energy saving, environmental protection, and high-efficiency modernization development, there is currently no reasonable solution. The present invention fills the gap in this field
