Abstract
Description
Technical Field
[0001] This utility model relates to the field of building construction safety technology, and in particular to a connector for strengthening the fixing of aluminum mullions to the structure. Background Technology
[0002] Aluminum windows are a commonly used window material in modern buildings. Due to their excellent corrosion resistance and lightweight properties, they are widely used in various building environments. In the manufacturing process of aluminum windows, the mullion is an important component.
[0003] A search revealed Chinese patent CN216714236U, which discloses a mullion connector including a plug-in end and a spiral end. The plug-in end and the spiral end are coaxially arranged and integrated. This utility model mullion connector includes a plug-in end and a spiral end that are coaxially arranged and integrated with the plug-in end. By spirally connecting the spiral end to a second profile, the mullion connector is fixedly connected to the second profile. Furthermore, by inserting the plug-in end into a first profile, the first profile and the second profile are seamlessly and tightly connected. Neither the profiles nor the mullion connector require a structure for mutual interlocking, resulting in a simple structure and convenient and easy installation.
[0004] This utility model also discloses a connection structure for the mullion.
[0005] Based on the above search results combined with existing technologies, the findings were as follows:
[0006] The aforementioned patents have certain limitations in the installation of aluminum windows. Sometimes, due to the large gap between the opening and the aluminum window frame, ordinary fixing plates cannot be used for fixing, or the outer window frame has a large fixing plate, which cannot meet the stability requirements. Utility Model Content
[0007] To address the aforementioned technical problems, this utility model proposes a connector for strengthening the fixing of the mullion aluminum window to the structure, ensuring the firmness of the connection and extending the service life of the aluminum window.
[0008] The technical solution to achieve the purpose of this utility model is: a connecting component for strengthening the fixing of aluminum window mullions to the structure, including an aluminum window and a wall, wherein aluminum window mullions are fixedly connected to both the upper and lower sides of the aluminum window, and each aluminum window mullion has a mullion cavity inside, and also includes a fixing connecting component;
[0009] A fixed connector, comprising a galvanized square steel pipe inserted into the cavity of the mullion.
[0010] Preferably, a galvanized iron plate is fixedly installed at one end of the galvanized square steel pipe, and a pair of round holes are provided on the galvanized iron plate.
[0011] Preferably, a pair of circular holes are respectively disposed on both sides of the galvanized square steel pipe, and each of the circular holes is threaded with an expansion bolt.
[0012] Preferably, the aluminum window is installed inside the wall using expansion bolts.
[0013] Compared with existing technologies, the significant advantages of this invention are:
[0014] Firstly, this utility model, by opening a round hole and installing expansion screws, ensures a tight connection between the aluminum window and the wall, improving the stability and firmness of the connection and extending the service life of the aluminum window.
[0015] Secondly, the materials used in this utility model are lightweight and durable, with high economic and practical value, making it easy for workers to install and maintain, thus improving construction efficiency.
[0016] This solves the problem of existing aluminum window frames not being securely fixed, or the gap between the aluminum window and the structure being too large, which cannot guarantee the stability of the finished aluminum window. Attached Figure Description

[0026] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.
[0027] This utility model provides an improved connector for strengthening the fixing of aluminum mullions to the structure. The technical solution of this utility model is as follows:
[0028] like Figures 1-6 As shown, a connector for strengthening the fixing of aluminum window mullions to the structure includes an aluminum window 1 and a wall 7. Aluminum window mullions 2 are fixedly connected to both the upper and lower sides of the aluminum window 1. Each aluminum window mullion 2 has a mullion cavity 201 inside, which helps to improve the construction quality and make the aluminum window 1 and the structure tightly connected. It also includes a fixing connector.
[0029] The fixing connector includes a galvanized square steel tube 5 inserted into the mullion cavity 201, which reduces the gap between the aluminum window 1 and the structure and ensures that the frame of the aluminum window 1 is firmly fixed.
[0030] Furthermore, a galvanized iron plate 3 is fixedly installed at one end of the galvanized square steel pipe 5. A pair of round holes 4 are opened on the galvanized iron plate 3, and bolts are installed through the round holes 4, which facilitates worker operation and shortens construction time.
[0031] Furthermore, a pair of round holes 4 are respectively set on both sides of the galvanized square steel pipe 5, and each round hole 4 is threaded with an expansion bolt 6. After installation, the expansion bolt 6 is not easy to loosen, has strong shock resistance, and ensures the stability and firmness of the connection.
[0032] Furthermore, the aluminum window 1 is installed inside the wall 7 by expansion bolts 6, which facilitates the installation and removal of the aluminum window 1 by construction workers, improves the construction speed, and is beneficial for later maintenance and repair.
[0033] The specific working method is as follows: First, prepare a 100mm long 30*40*2 galvanized square steel pipe 5 and a 140*70*2 galvanized iron plate 3, and weld them together to form a fixed connector. Second, make a pair of round holes 4 on the surface of the galvanized iron plate 3 to prepare for the installation of expansion screws 6. When the aluminum window 1 is installed, insert one end of the galvanized square steel pipe 5 into the mullion cavity 201 of the aluminum window mullion 2, and fix the expansion screws 6 to its surrounding structure through the round holes 4 on the galvanized iron plate 3.
[0034] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
