Description

Modular combined aluminum alloy window corner connection structure Technical Field The utility model belongs to the technical field of alloy door and window manufacturing, and particularly relates to a modular combined aluminum alloy window corner connecting structure. Background Traditional aluminum alloy window corner connection structure adopts welding or simple bolt fastening mode more, has that installation effectiveness is low, structural stability is not enough, difficult scheduling problem of adjustment. Especially when horizontal section bar and perpendicular section bar are right angle amalgamation, if only rely on welding or ordinary screwed connection, easily lead to junction to become flexible or warp because of the exogenic action, influence window form overall seal nature and life. In addition, lack of accurate spacing design to the connecting piece among the prior art, it is difficult to align when leading to the equipment, and later maintenance or dismantlement are also comparatively difficult. Therefore, there is a need for a corner connection scheme that is quick to install, ensures structural strength, and is adjustable and removable. Disclosure of utility model The utility model aims to provide a modularized combined aluminum alloy window corner connecting structure for solving the problems of low installation efficiency, insufficient structural stability, difficulty in adjustment and the like of a common alloy window. The utility model realizes the aim through the following technical scheme that the vertical sectional material comprises a horizontal sectional material and a vertical sectional material, the joint of the horizontal sectional material and the vertical sectional material is in a right-angle split shape, the inner sides of the horizontal sectional material and the vertical sectional material are fixedly provided with metal planes for installation, an insert connecting piece and an insert limiting piece are arranged between the horizontal sectional material and the vertical sectional material, and the insert connecting piece is connected with the vertical sectional material through screws after passing through the insert limiting piece. Further, the plug-in connector comprises a rigid screw column, a threaded hole is milled at one end of the rigid screw column, a round abutting block is fixedly arranged at the other end of the rigid screw column, the abutting block is connected with the metal plane on the inner side of the horizontal section bar in a welding mode, and the rigid screw column and the vertical section bar are fixed with the threaded hole through screws. Furthermore, a limiting ring is sleeved outside one end of the rigid screw column, and the limiting ring is fixedly connected with the inner wall of the vertical section. Furthermore, the plug-in limiting piece comprises a mounting plate, a plurality of metal limiting pieces with U-shaped openings on the inner sides are equidistantly arranged at the bottom of the mounting plate and fixedly connected, and the mounting plate is welded and connected with the metal plane on the inner sides of the vertical sections. Further, the metal limiting plates are clamped on the outer sides of the rigid screw columns, and the side surfaces and the bottom surfaces of the metal limiting plates are connected with the inner walls of the horizontal section bars. Further, one end surfaces of the abutting block and the limiting ring are abutted with the metal limiting sheet.
