Description

Aluminum alloy door and window strengthens well stile structure Technical Field The utility model belongs to the technical field of aluminum alloy house structures, and particularly relates to an aluminum alloy door and window reinforcing middle stile structure. Background The muntin is a division structure for distinguishing frames and splicing frames of doors and windows, and the doors and windows are divided into different area areas, so that the defect of insufficient glass strength caused by overlarge area of window sashes can be avoided. In the aluminum alloy door and window structure, the middle stile is made of aluminum alloy sections, and two sides of the middle stile section are respectively provided with different glass window sashes. If the area design of the window sashes of the existing aluminum alloy doors and windows is larger, when outdoor wind pressure is strong, the middle stile section bar can receive a large load, if the strength and rigidity of the section bar are insufficient, the section bar can be bent, bending stress is transmitted to the glass window sashes, and glass breakage accidents can be caused. If the existing door and window middle stile section bar can be reinforced in the later period, the rigidity of the middle stile section bar is improved, and the occurrence of the above situation can be avoided. Disclosure of Invention In order to solve the problems, the utility model provides an aluminum alloy door and window reinforcing mullion structure which is used for being installed and fixed on a mullion section bar of the existing aluminum alloy door and window, and can play a role in increasing the mullion strength and rigidity and increasing the stability and wind resistance of the door and window. The specific scheme of the utility model is as follows: a middle stiffening beam is fixed on the outer surface of an existing middle stiffening frame, and the middle stiffening beam is fastened with the existing middle stiffening frame by screws. The stiffening beam clings to the existing middle stile, so that the stiffening beam and the middle stile are stressed together, the rigidity and the strength of the existing middle stile are improved, and the deflection is reduced. The middle stiffening beam is provided with a processing hole at the position with screw fastening for penetrating the screw, and the middle stiffening beam is not required to be provided with a processing hole at the position without screw fastening. The cross section of the stiffening beam is a hollow cavity, the stiffening beam is contacted with the outer wall of the existing stiffening beam to form a foot part, the screw thread part penetrates through the inner wall of the cavity, and the end part is fastened with the outer wall of the existing stiffening beam in a threaded manner. The rubber strip groove is formed in the contact position of the foot and the outer wall of the existing middle stile, and the rubber strip is placed in the rubber strip groove. A cavity is formed between the foot and the existing middle stile, the function of the cavity is that 1, the adhesive tape of the foot is in line contact with the outer wall of the existing middle stile to form a closed chamber cavity, the sealing performance is better, rainwater is prevented from penetrating into a screw from the outside to cause rusting of the screw, 2, the cantilever length for fastening the screw is increased, the screw fastening effect is better, the screw is not easy to fall off, 3, the inner side wall of the middle stile reinforcing beam generates certain elastic deformation after the screw is anchored, the screw is tensioned, and the screw can be prevented from loosening to a certain extent. And a cover plate groove is formed in the outer side of the middle stiffening beam, and the cover plate is fixedly embedded with the cover plate groove. The apron can prevent that the rainwater from entering into the roof beam body inner chamber, prevents that the screw from rustting, and the outward appearance is more pleasing to the eye. Reinforcing ribs are arranged on the inner side wall of the middle stiffening reinforcing beam, and the reinforcing ribs further improve the rigidity of the reinforcing beam. The utility model has the advantages that: 1. the structure of the utility model is specially used for reinforcing the middle stile section bar of the aluminum alloy door and window, and can play the roles of increasing the strength and rigidity of the middle stile and increasing the stability and wind resistance of the door and window. 2. The stiffening beam has good tightness, prevents the fastening piece from being corroded, is convenient to install, and can be installed by directly using the screw.
