Combined type isolation fence fixed by joggling plug pins

Abstract

The invention discloses a combined isolation fence fixed by mortise and bolt. It consists of at least two uprights and horizontal bars arranged between two adjacent uprights. The vertical sides of the uprights are provided with the same For the I-shaped steel structure of the through-slot of the structure, at least two sets of corresponding fixing blocks are vertically provided in the two through-slots on the opposite sides of the two adjacent columns, and the fixing blocks are vertically arranged on the vertical surface away from the column. There are slots perpendicular to the inner bottom surface of the through groove, and tenons that can be inserted into the slots for fixing are provided at both ends of the cross bar; and the tenons are provided with vertical through holes, and the fixed block is provided with There is a positioning groove corresponding to the through hole, and the opening of the positioning groove is set on the upper surface of the fixed block; insert the tenons at both ends of the cross bar into the slots on the corresponding side and insert the pin into the positioning groove for fixing. The pin passes through the through hole and passes through one end to abut against the bottom of the positioning groove to achieve a fixing effect, which has better installation efficiency.

Description

technical field

[0001] The invention relates to the field of guardrail equipment, in particular to a combined isolation fence fixed by mortise and bolts. Background technique

[0002] The isolation fence is a guardrail structure, and the guardrail refers to an industrial "guardrail". Guardrails are mainly used for the protection and protection of personal safety and equipment and facilities in residences, highways, commercial areas, public places and other occasions. Guardrails can be seen everywhere in our lives. Depending on the height of the guardrail, the price per meter of length will also vary. The guardrail is usually made of steel, such as: stainless steel, round steel pipe, square steel pipe or profiled steel plate, iron wire. Surface treatment process: automatic electrostatic powder spraying (that is, plastic spraying) or painting. In recent years, plug-in and assembled guardrails made of aluminum alloy have become more popular. It is usually made of steel, su...
