Wood-aluminum composite-type door window

Abstract

The invention discloses a wood-aluminum composite-type door window which comprises a window frame and a window leaf. The window frame comprises a wood frame arranged on the indoor side and aluminum frames arranged on the outdoor side, grooves with cross sections in the shape of inverted trapezoids are formed in the wood frame, a clamping-connecting groove symmetrically formed by two dovetail grooves is formed in each aluminum frame, dovetail connecting members are arranged between the grooves and the clamping-connecting grooves, each dovetail connecting member comprises an embedding end and a clamping-connecting end, the upper end of each embedding end is formed by two symmetrically-arranged Z shapes while the lower end of the same is T-shaped, the upper end and the lower end of each embedding end form three glue injecting grooves, the cross section of each clamping-connecting end is trapezoidal, the embedding ends are embedded in the grooves, two clamping-connecting arms of each clamping-connecting groove extend in the corresponding groove and are connected with the clamping-connecting end in a clamped manner, and glue is filled in the glue injecting grooves. The dovetail connecting members are arranged between the wood frame and the aluminum frames, and can prevent water drops on the aluminum frames from entering the wood frame, so that the wood frame is ensured not to deform after being affected with damp; the dovetail connecting members can barrier heat transfer of the aluminum frames, so that the door window is enabled to have good heat insulation effect.

Description

technical field [0001] The invention relates to a door and window, in particular to a wood-aluminum composite door and window with high combination precision of aluminum profile and solid wood and good heat insulation effect. Background technique [0002] The performance of doors and windows is different due to the range of use, but there are usually two aspects to consider: one is strength, which is mainly reflected in the selection of profiles for doors and windows, whether it can withstand ultra-high pressure; the other is air tightness , It is mainly reflected in the structure of doors and windows, whether the inner leaf and outer frame structure of doors and windows are tight, and whether the doors and windows are tight. Doors and windows are divided into enclosure components or partition components according to their positions, which have different design requirements. The usual requirements for doors and windows are: thermal insulation, heat insulation, sound insulat...

Problems solved by technology

[0006] The defect in this patent document is that the aluminum frame layer and the solid wood frame layer are directly composited together by using the aluminum frame connecting bar assembly to insert the solid wood fan frame connecting groove assembly. When the weather is cold, the aluminum frame layer located outside It is easy to condense to form water droplets, and the water droplets will directly immerse into the solid wood fan frame connection groove assembly along the aluminum frame connecting strip assembly. During long-term use, the solid wood frame layer is easy to be damp and deformed, which will deteriorate the bonding accuracy of the solid wood frame layer and aluminum frame layer. The aluminum frame connecting strip assembly is prone to loosening, which affects the normal use of aluminum-wood doors and windows; in addition, because the aluminum frame layer and the solid wood frame layer are directly combined through the aluminum frame connecting strip assembly, the heat generated by the aluminum frame layer being exposed to the sun will directly It is transmitted to the solid wood frame layer through the aluminum frame connecting strip assembly, which greatly affects the heat insulation effect of aluminum wood doors and windows
