Abstract
The utility model discloses a kind of self-closing protective guard, guardrail main body is fixed on structure wall by fastening devices, main body underhung shelves sole, described fastening devices is: fixed head front transverse weld short tube, the external diameter that the internal diameter of short tube is greater than cross tube makes cross tube end can insert in short tube and can along cross tube axial rotation, and fixed head is fixed on structure wall by expansion bolt.This protective guard is installed firmly, and security performance is high, can not arbitrarily be moved; Elegant in appearance, meet civilized construction requirement; The design of this guardrail fastening devices is ingenious, makes guardrail freely can upwardly open and can automatically close.
Description
Technical field
The utility model relates to protective guard in a kind of work progress, specifically a kind of self-closing protective guard.
Background technology
At present, building operations is faced limit temporary protection railing many employings scaffold tubes and to be set up or reinforcement welding forms, and this protection type poor stability, is easily moved, unsightly, is difficult to play safety protection function.
Utility model content
The purpose of this utility model solves the problem, design a kind of safe, attractive in appearance, fixing, can open, self-closing guard rail.
The technical solution of the utility model is achieved in that self-closing protective guard, guardrail main body is fixed on structure wall by fastening devices, main body underhung foot guard plate, it is characterized in that, described fastening devices is: fixed head front transverse weld short tube, the external diameter that the internal diameter of short tube is greater than cross tube makes cross tube end can insert in short tube and can along cross tube axial rotation, and fixed head is fixed on structure wall by expansion bolt.
Described guardrail main body is: two parallel cross bars, and weld some vertical rods perpendicular to cross bar between cross bar, the distance≤110mm between adjacent vertical rod, the length of cross tube and sheer pole is greater than the lateral separation between structure wall.
The length of described short tube is between 4 ~ 10cm.
Described foot guard plate is: comprise the connection cross bar of top and the rectangular flat of below, connects between cross bar and rectangular flat and is welded to connect vertical rod, and the connection cross bar of foot guard plate is suspended on main body sheer pole by connecting folder.
Described connection folder is: two panels sheet metal is oppositely arranged, every sheet sheet metal is bend up and down, middle line part, the line part passing perpendicularly through two panels sheet metal of having strong market potential makes two panels sheet metal fix, and the curved surface of bend all mates with the side wall surface of the sheer pole of main body and the connection cross bar of foot guard plate.
The beneficial effects of the utility model are: this protective guard is installed firmly, and security performance is high, can not arbitrarily be moved; Elegant in appearance, meet civilized construction requirement; The design of this guardrail fastening devices is ingenious, makes guardrail freely can upwardly open and can automatically close.
