Topping type door and window fixing fitting

Abstract

The invention provides a topping type door and window fixing fitting, which comprises a transverse plate for being connected with a door and window frame, a first side plate and a second side plate which are used for being pressed and attached to the front and rear side faces of a wall correspondingly are arranged at the two ends of the transverse plate, the transverse plate and the first side plate and the second side plate can form a pi-shaped structure, a detachable through-wall connector is arranged between the first side plate and the second side plate, a plurality of wall tightening adjusting bolts are arranged on the transverse plate, the first side plate and the second side plate at intervals correspondingly, and a plurality of nail plates for external components to be connected ina nailed mode are arranged on the transverse plate, the first side plate and the second side plate in an embedded mode correspondingly. According to the topping type door and window fixing fitting, installation and removal are convenient, connection and fixation are reliable, the wind bearing ability is high, and the door and window frame cannot be damaged when topping type door and window fixingfittings are removed so that the door and window frame can meet the requirements of secondary utilization and can further meet the higher level decoration requirements such as plastering, door pasting and wall pasting on the door and window frame.

Description

technical field [0001] The invention relates to the construction field, in particular to a sleeve-type door and window fixing fitting. Background technique [0002] With the development of residential buildings and other civil buildings, the service life of building structures increases, while the service life of building door and window accessories is relatively short. In addition to the development of new technologies, door and window structural materials are constantly updated, or building uses change, and door and window replacements often occur. In addition, as the height of the building increases, the windward force that doors and windows need to withstand increases, which puts forward higher requirements for the current fixing of door and window frames and walls. At present, the fixing structure of the door and window frame and the wall has the following problems: only cement mortar or concrete is used to fill the fixed door and window frame, and the thermal expansion...

AI Technical Summary

Problems solved by technology

At present, the fixed structure of the door and window frame and the wall has the following problems: only cement mortar or concrete is used to fill the fixed door and window frame, and the thermal expansion and contraction coefficients between different materials are different. After a period of time, it is easy to loosen and the fixation is not firm. Moreover, when replacing doors and windows, the removal of the frame is difficult, and it is easy to cause damage to the profile of the door and window frame, which cannot be effectively reused, resulting in a waste of social resources
