[0031] Example 1

[0032] High-altitude safety guardrail used for steel structure installation

[0033] figure 1 Is a schematic plan view of the structure of the support rod of the embodiment of the present invention, figure 2 for figure 1 A-A sectional view in. As shown in the figure, the support rod is a 1.2m long channel steel 1 used as a vertical rod. Two pieces of the first steel plate 2 and the second steel plate 3 with a thickness of 10mm with a distance of 3cm are welded up and down symmetrically at the root of the vertical rod. The first steel plate 2 is welded side by side with two M20 nuts, the matching movable bolt 4 is installed in the nut, and the first diagonal brace stiffening plate 5 is provided on the upper part of the first steel plate. One side is welded to the upper part of the second steel plate, and the other side is connected with Channel steel 1 is welded; a second diagonal brace stiffening plate 6 is provided under the second steel plate, one side of wh...

Abstract

The invention relates to a high-altitude safety fence for steel structure assembling. The high-altitude safety fence is assembled on a steel beam and comprises a support rod and a steel wire rope. The high-altitude safety fence is characterized in that the support rod is characterized in that a 1-1.3m steel channel (1) serves as a stand rod, a first steel plate (2) and a second steel plate (3) are symmetrically welded to the upper portion and the lower portion of the root of the stand rod, the thickness of the first steel plate (2) and the thickness of the second steel plate (3) are both 10mm, the distance between the first steel plate (2) and the second steel plate (3) is 3cm, and two nuts are welded to the first steel plate (2) side by side; when the support rod is installed, the first steel plate (2) and the second steel plate (3) are clamped on a frange plate of the steel beam, and the steel beam and the steel channel (1) are fixed through two movable bolts (4); a third steel plate (7) is welded to the top of the front elevation face of the steel channel (1), and a circular hole (8) is formed in the middle of the third steel plate (7); the steel wire rope is inserted in the circular hole (8) in the third steel plate (7) of the front elevation face of the steel channel (1). The high-altitude safety fence has the advantages of being easy to manufacture, convenient to assemble and disassemble and capable of being repeatedly used, effectively eliminating the risk that an operator falls down from the high positions, and improving the working efficiency.

Description

technical field [0001] The invention relates to a guardrail, in particular to a high-altitude safety guardrail for steel structure installation and a manufacturing method thereof. Background technique [0002] There are many high-altitude operations in the installation of steel structures, and the construction period is short. Casualties often occur due to inadequate or unreasonable safety measures. There are generally two types of conventional safety belt hanging points: 1. Set a safety rope from the cornice to the roof ridge (wire rope, the diameter is determined by calculation), and the safety rope is tied to the purlin support plate at the cornice and the roof ridge and is close to the steel beam. , When the workers are working on the roof, the safety belts are hung on the safety ropes. The disadvantage of this method is that the operator needs to move at any time, the distance between the big rope and the person is relatively large, the safety belt hook is inconvenient...
