Door and window casement and mounting method thereof

Abstract

The invention discloses a door and window casement, which comprises a first casement face, a second casement face, and a door and window casement side edge arranged between the first casement face and the second casement edge, wherein the door and window casement side edge is wrapped with a mounting frame; and hardware fittings of the door and window casement are mounted on the door and window casement side edge through door and window casement side edge. Through the adoption of the door and window casement, the characteristics that the door and window casement is strong in mounting stability, not easy to deform, reasonable in stress, safe in structure, and environmental in technology are realized; by covering edges with profiles around the door and window casement, the mounting and the stress of the hardware fittings are delivered to the door and window casement through the overall edge covering and a reinforcing subplate, rather than only depending on the interlocking ability of the material of the door and window casement and screws, so that the stability for the fastening mounting of the hardware fittings and the door and window casement is strengthened, the structure is more reasonable, and the door and window casement is not easy to be deformed and cracked.

Description

technical field [0001] The invention relates to a building component, in particular to a door and window sash and an assembly method thereof. Background technique [0002] The main functions of doors and windows are enclosure, separation and traffic evacuation (mainly doors), as well as lighting, ventilation and decoration. To ensure the normal performance of the above functions, factors such as the strength and quality of the door and window sash itself are important, but what is more critical and easily overlooked is the door and window sash and the surrounding door and window frame (set) or wall (hereinafter referred to as the door and window frame) ) of the fastening installation quality. [0003] As for the wooden door and window sashes, the fastening installation with the door and window frame is mainly realized by the mutual engagement between hardware such as hinges, locks or hanging wheel mounting parts and supporting screws. Further analysis of the force of the c...

AI Technical Summary

Problems solved by technology

[0005] 1. The material of wood is ever-changing, and its ability to bite with screws is also different; in addition, the manufacturing process of the door leaf will also directly affect the bite of wood and screws, such as solid wood, finger joint, laminated, molded and even some composite materials, etc. The above factors all lead to uneven bite effect between the screw and the wood, and the stability of the corresponding wooden door and window sashes after installation is also difficult to guarantee;

[0006] 2. Because the hinge specifications of the casement doors and windows are limited, and the thickness of the doors and windows is different, the installation holes of the hinge screws are often not at the best occlusal position of the doors and windows, that is, the center of the thickness. When the force is applied, it is easy to cause The doors and windows are cracked or deformed, affecting the use of doors and windows and posing safety hazards;

[0007] 3. The contact surface between the hinge and the casement door and window sash is small. When subjected to the combined load of the above-mentioned longitudinal gravity, lateral overturning force and transverse frontal impact force, it is easy to cause deformation or cracking of the material on the edge of the door and window sash, and the hinge is loose. The use of doors and windows leaves potential safety hazards;

[0008] 4. The lock installation is generally made from the side of the door and window sash, which will directly cause the strength of the side stiles near the lock to decrease. When the front impact force perpendicular to the door and window sash is received, the nearby side stiles are easily cracked or even damaged. damage, the lock will become invalid and there will be a safety hazard;

[0009] 5. Due to the characteristics of the material, wood itself is easy to deform due to factors such as the environment. When it is in the above-mentioned irregular force state for a long time after installation, the deformation will be aggravated, resulting in loose doors and windows, partial cracks, difficulty in opening and closing, etc. Problems affecting the normal use of doors and windows;

[0010] 6. Since the four sides of wooden doors and windows are exposed, they are prone to rubbing during transportation, installation and use, resulting in damage to the paint on the corners or damage to the doors and windows, affecting the appearance and use;

[0011] 7. Since the four sides of wooden doors and windows are no longer provided with other decorative layers, they are all finished surfaces, so the manufacturing process should be exactly the same as that of the front of the doors and windows, such as sticking veneer, paint, etc., which is labor-intensive and time-consuming and difficult to do well

However, if the product itself has inherent deficiencies, I believe that no matter how good the installation is in the later stage, it will be difficult to cover up all the problems.

The above-mentioned existing wooden door and window sash structures have certain defects in the installation methods of hardware accessories, and there are no targeted solutions and technical solutions. The establishment of standards and specifications for real product attributes that are different from the acceptance standards for engineering doors and windows is not conducive to the management and supervision of the industry by relevant departments

[0014] However, with the progress of the times, the professional technologies of all walks of life are constantly updated, but the core technology that can effectively improve the safety and convenience of wooden door and window sashes installation 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
