Connecting structure of corner frame and handrail outer frame

Abstract

The invention discloses a connecting structure of a corner frame and a handrail outer frame. The connecting structure comprises the corner frame and a corner outer frame assembly with a 90-degree corner, wherein the corner frame is fixedly connected with the corner outer frame assembly through a vertical corner connector; and the corner outer frame assembly comprises handrail outer frames with 45-degree cut angles, wherein the handrail outer frames are connected through a first transverse corner connector and a second transverse corner connector on the same plane. The corner frame is simple in structure, can be matched with an L-shaped strip-shaped plate to form a square tube under the condition of meeting corner use, is applied to other parts of doors and windows, and is high in practicability, the corner position of the corner frame can be converted between a round corner and a right angle to adapt to different building styles, for manufacturers, the production cost is reduced, the use of materials is reduced, the waste is avoided, the resources are saved, the energy consumption of the production line and the emission of pollutants are correspondingly reduced, and the national energy-saving and environment-friendly policy is responded.

Description

technical field [0001] The invention relates to the technical field of doors and windows, in particular to a connection structure between a corner frame and a railing outer frame. Background technique [0002] Traditional doors and windows are separated from the exterior design of the building. Doors and windows are just a separate product of themselves. The construction party needs to redesign the facade of the building, and it is independent of the design of doors and windows as a building. There are certain difficulties in the installation and construction of doors and windows, and it may even cause difficulties in the installation of doors and windows or in the construction of building facade decoration. Secondly, the construction of building facades is often completed outside the building, and the construction safety factor is low.

Problems solved by technology

[0002] Traditional doors and windows are separated from the exterior design of the building. Doors and windows are just a separate product of themselves. The construction party needs to redesign the facade of the building, and it is independent of the design of doors and windows as a building. There are certain difficulties in the installation and construction of doors and windows, and it may even cause difficulties in the installation of doors and windows or in the construction of building facade decoration. Secondly, the construction of building facades is often completed outside the building, and the construction safety factor is low. Based on the above-mentioned problems, a one-piece window combining doors, windows and building facades has emerged as the times require, but the existing one-piece window has the following defects

[0003] (1) The existing corner frame is complex in structure, difficult to process, difficult to transport, and labor-intensive to carry during installation, resulting in too high manufacturing cost of the corner part. Disadvantages such as poor sealing performance;

[0004] (2) The structure of the decorative window sill outside the building is split, which requires secondary assembly and installation, which is time-consuming and laborious. At the same time, there will be serious water seepage problems in the building due to unreasonable installation;

[0005] (3) The outer frame is generally equipped with a drainage notch, but the existing drainage notch has poor drainage effect. When the wind and rain are too heavy, the rainwater is easily blown back by the strong wind, causing the backflow phenomenon to affect the drainage, and in severe cases, it seeps into the building;

[0006] (4) For different decoration styles, the chamfers cannot be replaced, and different types of corner frames need to be produced, resulting in waste of materials
