Detailed Description
As shown in fig. 1 and 2, the utility model provides a pair of assembled landing stage guardrail has guardrail pole setting 3 at 2 end connection of spandrel girder worker steel of 1 both sides of landing stage, is connected with multirow guardrail horizontal pole 4 between 3 guardrail pole settings of landing stage every side. Two box-type clamping plates 5 are arranged at the joint of each guardrail upright rod 3 and the I-steel 2.
The box-type clamping plate 5 is structurally shown in fig. 3 and 4, and comprises two vertical plates 51 which are parallel to each other and have a certain interval, a U-shaped bayonet 52 is arranged in the middle of the same side of the two vertical plates 51, a threaded hole 53 which penetrates through the two vertical plates is arranged above the U-shaped bayonet 52, a bottom plate 54 is welded between the bottom edges of the two vertical plates, a top plate 55 is welded between the top edges of the two vertical plates, and the width of the top plate 55 is smaller than the length of the top edge of the vertical plate 51.
As shown in fig. 5, 6 and 7, the two box-type clamping plates 5 are respectively clamped on two sides of the upper flange plate of the i-steel 2 through the U-shaped bayonets 52 on the vertical plates 51, because the width of the top plate 55 is smaller than the length of the top edge of the vertical plate 51, a gap is formed between the top plates 51 of the two box-type clamping plates 5, the lower end of the vertical rod 3 is inserted into the gap between the top plates of the two box-type clamping plates 5 and is supported on the top surface of the upper flange plate of the i-steel 2, and a bolt 6 crossing the vertical rod is inserted into the through screw hole on the two vertical plates of each box-; a through hole is formed in the upright rod 3 at intervals, each row of guardrail cross rods 4 penetrate through the through holes in the upright rods, and a positioning bolt 7 is inserted into the position, close to each guardrail upright rod, of each guardrail cross rod.
