Ventilation duct support frame structure

Abstract

A ventilation duct support structure mainly comprises a frame and a fastener. The frame is generally L-shaped, including a vertical section and a horizontal section. The vertical section has a plurality of fixing holes, and the horizontal section has a plurality of elongated holes. The fastener is an elongated sheet with a fastening part at one end and a bent section at the other end, where a positioning hole is provided. During construction, the frame is fixed to the wall using the fixing holes. The fastening part of the fastener passes through the elongated hole in the horizontal section and is fastened therein. The ventilation duct is then placed on the horizontal section of the frame, and the other end of the fastener passes around the ventilation duct, placing the bent section in the elongated hole. The fastener passes through the positioning hole and the elongated hole and locks in place, thus fixing the ventilation duct to the frame. This makes the installation of the ventilation duct more convenient, faster, and more efficient, and also results in a neater and more aesthetically pleasing finished ventilation duct installation.

Claims

1. A ventilation duct support frame structure, comprising: a frame body, including a vertical section and a horizontal section for placing a ventilation duct, wherein the vertical section has a plurality of fixing holes for fixing to a wall, and the horizontal section has a plurality of elongated holes; a fastener, which is an elongated sheet body, having a fastening portion near one end; the other end is a bent section, having a positioning hole in the bent section; so that during construction, the fastening portion of the fastener passes through the elongated hole of the frame body and is fastened in the elongated hole, and then the other end of the fastener passes around the ventilation duct so that the bent section is placed in the elongated hole, so that the fastener passes through the positioning hole and the elongated hole and is locked, thereby fixing the ventilation duct to the frame body.

2. The ventilation duct support structure as described in claim 1, wherein, The vertical and horizontal sections of the frame are respectively provided with vertical reinforcing ribs and horizontal reinforcing ribs of appropriate length to improve the strength of the frame.

3. The ventilation duct support structure as described in claim 1, wherein, The fastener has inward notches on both sides near one end of the fastener to form the fastening part.

4. The ventilation duct support structure as described in claim 1, wherein, The width of the fastening portion of the fastener is equal to or smaller than the elongated hole of the horizontal section of the frame, so as to facilitate the insertion of the elongated hole and fastening to the elongated hole.

5. The ventilation duct support structure as described in claim 1, wherein, The fastener can be configured to various lengths to meet the construction requirements of ventilation ducts with different diameters.
