Embodiment Construction

[0016] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0017] Such as figure 1 , figure 2 and image 3 The height-adjustable temporary standard barrier shown includes a primary construction barrier and a secondary safety barrier. The first-level construction guardrail includes vertical steel pipes 1, horizontal steel pipes 2 and sleeves 3. The vertical steel pipes 1 are anchored to the ground and are provided with multiple steel pipes. The top of the vertical steel pipe 1 is also welded with a sleeve 3, and the sleeve 3 is a hollow steel pipe. Two horizontal steel pipes 2 are arranged between every two adjacent vertical steel pipes 1, and the two ...

Abstract

The invention provides a height adjustable type temporary standard guardrail comprising a first grade construction guardrail body and a second grade safety guardrail body. The first grade construction guardrail body comprises two or more vertical steel pipes, horizontal steel pipes and sleeves. The vertical steel pipes are anchored to the ground, and the sleeves are further welded to the upper portion of the vertical steel pipes and are hollow steel pipes. Each horizontal steel pipe is arranged between every two adjacent vertical steel pipes and welded to the two adjacent vertical steel pipes. The second grade safety guardrail body comprises adjusting steel pipes, limiters and a steel wire rope. The outer diameter of each adjusting steel pipe is not larger than the inner diameter of the corresponding sleeve. The limiters are welded on the lower portions of the adjusting steel pipes. The adjusting steel pipes are inserted into the sleeves and vertically positioned through the limiters. A pair of through holes is further formed in the upper pipe wall of each adjusting steel pipe. The steel wire rope penetrates through all the through holes of the adjusting steel pipes, and the two ends of the steel wire rope are anchored to the ground. The structure is simple, manufacturing is convenient, the height of the guardrail can be easy and convenient to adjust, safety can be guaranteed, and construction is convenient.

Description

technical field [0001] The invention relates to the field of production safety, in particular to a temporary standard guardrail whose height can be adjusted. Background technique [0002] Guardrail is an indispensable temporary structure in engineering safety production work. It plays a vital role in isolating the construction site, preventing people from intruding and avoiding accidental injuries caused by falling objects. [0003] However, during on-site construction, due to site restrictions and other reasons, guardrails sometimes hinder the passage or operation of construction machinery, and the height of general guardrails is fixed. If the height of the guardrail is permanently reduced for the convenience of machinery, it will not be able to play its due role. protective effect. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a height-adjustable temporary standard guardrail, which aims to solve the problem ...
