Fastening positioning structure for aluminum alloy door and window

Abstract

The invention discloses a fastening positioning structure for an aluminum alloy door and window. The fastening positioning structure comprises a glass door and window body fixed in a side frame, wherein the side frame comprises a compression assembly and a fastening assembly; through the matching of the compression assembly and the glass door and window body, the fastening assembly is pressed to generate prestress, and the glass door and window body is further fastened; the glass door and window body becomes a main control element for generating prestress; the fastening assembly selects elastic materials; under the effect of external force, stable prestress can be formed inside the materials, and can be stored; and a stable prestress system is formed with the glass door and window body and the compression assembly. The fastening positioning structure has the advantages that the strength, the anti-twisting performance and the external-force-resistant capability of the whole aluminum alloy door and window structure can be enhanced; the occurrence of problems of door and window falling and deformation and the like is avoided; the side frame using a prestress structure on the periphery of the glass is used, so that a corresponding fastening point and a corresponding fastening mode can be set in any position of a side frame press block according to the fastening installing requirements of hardware fittings; the requirements of use function and firmness degree of the hardware fittings are met; and the limitation by the thickness of sectional materials is avoided.

Description

technical field [0001] The invention relates to a door and window, in particular to an aluminum alloy door and window and an assembly method thereof. Background technique [0002] Aluminum alloy doors and windows refer to a type of doors and windows that use aluminum alloy building profiles to make frames and fan rod structures. In the current national industry standard "Technical Specifications for Aluminum Alloy Doors and Windows Engineering" JGJ214-2010 and the National Building Standard Design Atlas "Aluminum Alloy Doors and Windows" 02J603-1, the description of the fastening and installation of glass in aluminum alloy doors and windows is roughly as follows: The form is placed in the frame or U-shaped groove of the aluminum alloy profile, and the supporting block is placed under it, and the surrounding area is supplemented with gaskets and sealants to complete the fixing of the door and window sash glass; and the hardware accessories such as hinges and handles are direc...

AI Technical Summary

Problems solved by technology

[0003] 1. The glass is placed in the frame or U-shaped groove of the aluminum alloy profile. The glass and the profile are not integrated, but only rely on the section splicing tension of the profile to counter the gravity load, wind load and external impact load of the glass door and window sash. etc. Therefore, the strength of the structure against external force is weak. Under the long-term action of the above-mentioned loads, aluminum alloy doors and windows are prone to failures such as vertical drop and deformation;

[0004] 2. The longitudinal glass is rested on the support block by the section, which is easy to generate destructive internal stress inside the glass. When the glass is subjected to external force, the diffusion of the internal stress will be aggravated, resulting in the destruction of the internal stress balance of the glass and triggering Danger;

However, at present, the installation of various hardware accessories for aluminum alloy doors and windows cannot be individually targeted according to the corresponding functional requirements, material requirements, and screw thread engagement requirements, but can only be unified on relatively thin profile wall thicknesses. Carry out hardware installation

This will inevitably lead to the installation point of the hardware becoming the weak point of the profile, affecting the strength and stability of the structure; it is also the main reason for the looseness of the doors and windows and the looseness of hardware accessories;

[0006] 4. The pads and sealants around the door and window sash glass are easy to age and lose their original functions, and the glass is prone to loosening or even falling;

[0007] 5. It is difficult to adjust and control the position of the glass when it is fixed in the aluminum frame, and the requirements for the production and processing precision of the glass and the profile are high, so there are often gaps between the glass and the frame, and the plane of the glass and the frame is skewed, etc. Phenomenon, affecting appearance and use;

[0008] 6. Due to structural constraints (such as the above point 1), there are currently certain restrictions on the maximum allowable use range of aluminum alloy doors and windows, and it is more difficult to increase;

[0009] 7. In order to resist the falling of the glass, the splicing surface of the profile is usually relatively large, which directly leads to an increase in the amount of aluminum alloy used, resulting in a common waste of resources such as raw materials and energy;

[0013] The glass installation and load-bearing structure of aluminum alloy doors and windows in the above-mentioned specifications and patents have certain defects, and there are no targeted solutions and technical solutions. Therefore, related safety hazards always exist and have become a major problem that has plagued relevant technical personnel.

[0014] However, with the progress of the times, professional technologies in all walks of life are constantly being updated, and people's demand for aluminum alloy doors and windows is also increasing. However, the core technology that can effectively improve the safety and convenience of aluminum alloy doors and windows has not yet been resolved.

For such problems that affect industrial upgrading and restrict energy saving, environmental protection, and efficient modernization, there is no reasonable solution at present, and the present invention fills the gap in this field
