Detailed Description

In the following, the technical solutions of the present invention are described clearly and completely, and obviously, the described embodiments are some, but not all embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by the skilled person in the art without making creative efforts belong to the protection scope of the present invention.

Examples

Referring to fig. 1-3, a conveniently installed and removed groove steel form hanger comprises:

the portal frame 100 comprises 2 symmetrically arranged triangular supports 101, a bearing rod 102 connected to the tops of the 2 triangular supports 101 and a sliding seat 103 which is sleeved on the bearing rod 102 and is in sliding fit with the bearing rod 102;

the adjusting piece 200 is fixed at the top of the portal frame 100 and positioned above the bearing rod 102, and the adjusting piece 200 is in threaded fit with the sliding seat 103 and drives the sliding seat 103 to slide along the bearing rod 102; specifically, the adjusting part 200 comprises a fixed seat 201, an adjusting screw 202 and an adjusting disc 203, wherein 1 fixed seat 201 is fixedly arranged at the top of each triangular bracket 101; the adjusting screw 202 is rotatably connected with 2 fixed seats 201, penetrates through the upper part of the sliding seat 103 and is in threaded fit with the sliding seat; the adjusting disk 203 is fixed on the end part of the adjusting screw 202;
