Description
Technical field
It the utility model is related to the attachment structure and door-window section bar of door-window section bar, and in particular to the interlocking of aluminum-plastic door-window profile
Formula attachment structure and aluminum-plastic door-window profile.
Background technology
Because aluminium alloy and the linear expansion coefficient of polyamide nylon (PA66) are very close to and aluminium alloy and plastics such as PVC
Linear expansion coefficient have a long way to go (aluminium alloy：2.26×10-3K-1, nylon66 fiber：2.4×10-3K-1, plastics：8×10-3K-1).
Due to the difference in a few this performance of money material, main flow door-window section bar is divided into substantially on existing market：Aluminium alloy extrusions, plastic-steel section bar
(PVC profile adds steel lining), aluminium alloy section bar (aluminium alloy adds PA66).And aluminium alloy and PVC are poor due to linear expansion coefficient
Away from more than 3 times, if huge hidden danger, danger can be produced in structural strength and airtight, watertight etc. by making composite structured section bar
Evil building body.
It is that aluminium alloy is incomparable that plastic material, which has a remarkable advantage, that is, heat-proof quality.So although shaped plastics
Material such as PVC intensity differences only have 50N/mm；Ageing resistance difference GB5237-6 (high temperature resistant, acid and alkali-resistance, uvioresistant)；Burning has
Penetrating odor；Not recoverable etc. shortcoming, but can not change its super large share in door and window in the market.
Aluminium alloy extrusions no matter from intensity (metal strength of aluminium itself, bonding strength caused by German injection process),
Uvioresistant, the rich of color, fire protecting performance etc. everyway are many better than PVC, but also it is poor not make up heat-proof quality
Shortcoming.
Aluminum-plastic door-window profile can deform because plastic material is nonsynchronous flexible with aluminium alloy extrusions, influence door and window framework
Structural strength.
For this reason, it may be desirable to seek a kind of technical scheme, at least to mitigate above mentioned problem.
The content of the invention
The technical problems to be solved in the utility model is to provide the rabbet joint type attachment structure and aluminium of a kind of aluminum-plastic door-window profile
Plastic door and window section bar, its be avoided that because plastic material and aluminium alloy extrusions linear expansion system difference cause it is flexible it is asynchronous cause
Deformation.
In order to solve the above technical problems, the utility model uses following technical proposals.
A kind of rabbet joint type attachment structure of aluminum-plastic door-window profile, the aluminum-plastic door-window profile include aluminium alloy extrusions and shaped plastics
Material, the rabbet joint type attachment structure include：
Groove, it is arranged at the plastic material and extended along the plastic material length direction, and it includes limiting section；
Connector, it includes first fitting portion and inserts the groove and by the limit along the plastic material length direction
Position portion is limited in the connecting portion in the groove；And
Second fitting portion, it is arranged at the aluminium alloy extrusions and can be chimeric with the first fitting portion；
Wherein, there is gap between the connector and the groove.
The groove is T-slot or dovetail groove.
The first fitting portion is groove, and the second fitting portion is the boss chimeric with the groove.
The groove extends along the plastic material length direction, and the boss extends along the aluminium alloy extrusions length direction.
The side wall of the groove is provided with the first convex shaped part, and the boss is provided with second fastened with first convex shaped part
Convex shaped part.
Length direction extension of first convex shaped part along the groove.
The plastic material includes the cavity extended along its length direction and the strength stiffener inserted in the cavity.
The strength stiffener is steel lining.
A kind of aluminum-plastic door-window profile, including above-mentioned rabbet joint type attachment structure.
The utility model has following advantageous effects.
Groove of the present utility model is arranged at plastic material and extended along plastic material length direction, and it includes limiting section；Even
Fitting includes first fitting portion and the connecting portion being limited in along plastic material length direction insertion groove and the portion of being limited in groove；The
Two fitting portions are arranged at aluminium alloy extrusions and can be chimeric with first fitting portion；There is gap between connector and groove.Aluminium alloy type
It is not fixedly connected with such as screw between material and plastic material to be spirally connected or gluing, the gap between connector and groove forms activity
Space, such aluminium alloy extrusions and plastic material will not form linkage because of confinement, in the case where the temperature difference is very big, monolithic devices
Material will not deform because aluminium alloy extrusions and plastic material are nonsynchronous flexible, and the structure of aluminum-plastic door-window profile has been effectively ensured
Intensity is unaffected, is addressed the difference of linear expansion problem of aluminium alloy extrusions and plastic material.
