Pressing component for installing an aluminum alloy door and window

Abstract

The invention discloses a pressing component for installing an aluminum alloy door and window, comprising a glass door and window body fixed in a frame. The frame comprises a pressing component and a tightening component. Through matching of the pressing component and the glass door and window body, the tightening component is pressed to generate pre-stressing force to tighten the glass door and window body. The glass door and window body serves as a main control part for generating the pre-stressing force. The tightening component is made of an elastic material, a stable pre-stressing force is formed inside the material under the action of external force and is stored, and the pre-stressing force forms a stable pre-stressing force system together with the glass door and window body and the pressing component. The strength, torsion property and external force resistance of the whole aluminum alloy door and window structure can be increased, and door and window drop, deformation and the like can be avoided. Because of the adoption of a pre-stressing force structure frame around the glass, corresponding tightening points and tightening modes can be set in any position of a frame pressing block according to the hardware fitting tightening and mounting requirement, so that the using functions and fastness requirements of hardware fittings are satisfied, without being limited by the thickness of profiles.

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
