Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of door and window structures, and particularly relates to a plastic steel door and window center support connector. Background Art
[0002] The center brace of doors and windows is a horizontal or vertical reinforcement in the window frame, which can increase the strength of doors and windows. The connection strength and sealing between the center brace and the window frame are crucial, and the processing capabilities of existing technologies in this regard need to be improved. Utility Model Content
[0003] In order to further improve the connection strength and sealing between the center support and the window frame, the utility model provides a plastic steel door and window center support connector. The utility model welds a connecting cap on the inner side of the steel lining, and the fastening nails of the window frame driven to the center support are connected to the connecting cap, thereby improving the connection strength and sealing.
[0004] The technical solution provided by the utility model is: a plastic steel door and window center support connector, comprising a center support profile, a window frame profile, a steel lining, a connecting cap, a steel plate and a fastening nail, the steel lining is located inside the center support profile and the window frame profile, the connecting cap is welded to the inner side of the end of the steel lining inside the center support profile, the steel plate is arranged on the outer side of the window frame profile, the steel plate and the center support profile are arranged on two opposite surfaces of the window frame profile, the window frame profile is provided with fastening nails toward the center support profile, the fastening nails sequentially pass through the steel plate, the window frame profile and the connecting cap of the steel lining end of the center support profile, the fastening nails successively pass through four steels, so that the window frame and the center support are connected by the tensile force of the four steels, and the connection state is more stable.
[0005] An improved technical solution is that the wall thickness of the connecting cap is not less than 2 mm.
[0006] An improved technical solution is that the number of the fastening nails is two or more.
[0007] An advanced technical solution is that the middle support profile is connected to the steel lining inside it by reinforcing nails.
[0008] The improved technical solution is: the fastening nail is a hexagonal self-rotating 410 white steel nail.
[0009] The connection cap in the utility model is located at the end of the steel lining in the middle support profile and is welded to the steel lining. The reliability of the welded connection is the highest, ensuring that the connection between the two is reliable and the relative state is stable. The connection between the window frame and the middle support of the utility model is completed by fastening nails passing through four steels, and the stability, reliability and sealing of the connection are greatly improved.

[0012] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.
[0013] like Figure 1 As shown, the utility model includes a center support profile 1, a window frame profile, a steel lining 2, a connecting cap 3, a steel plate 4 and a fastening nail 6. The steel lining 2 is arranged inside the center support profile 1 and the window frame profile 5. The connecting cap 3 is located on the inner side of the end of the steel lining 2 in the center support profile 1. The four sides of the connecting cap 3 are welded to the steel lining 2 by an automatic welding machine. The reliability and connection strength of the welded connection are the highest, ensuring that the connecting cap 3 and the steel lining 2 are in a relatively stable state. In order to ensure that the connection strength meets the requirements, the wall thickness of the connecting cap 3 is not less than 2 mm.
[0014] The middle brace is vertically installed on the inner side of the window frame profile 5, the steel plate 4 is arranged on the outer side of the window frame profile 5, the steel plate 4 and the middle brace are arranged on two opposite sides of the window frame profile 5, the window frame profile 5 is driven by a hexagonal self-rotating 410 white steel fastening nail 6 to the middle brace profile 1, and the fastening nail 6 passes through the steel plate 4, the window frame profile 5 (including the steel lining 2 inside the window frame profile 5) and the connecting cap 3 at the end of the steel lining 2 of the middle brace profile 1 in sequence. In this process, the fastening nail 6 passes through four steels 4 in sequence, so that the window frame and the middle brace are connected by the tension of the four steels 4, and the connection state is more stable. To further ensure the connection strength, the number of the fastening nails 6 is two or more.
[0015] The middle support profile 1 is connected to the steel liner 2 inside it via a reinforcing nail 7 .
[0016] The accompanying drawings of the present invention only show a schematic diagram of the structure in which one end of the center support is connected to the window frame. The scheme in which the other end of the center support is connected to the window frame is the same as the above-mentioned connection structure, so it will not be repeated.
