Technical Field

[0001] The utility model relates to the technical field of guardrails, in particular to a building guardrail for civil engineering. Background Art

[0002] Civil engineering is a general term for the science and technology of building various land engineering facilities. It refers to the materials, equipment used, and the technical activities such as survey, design, construction, maintenance, and repair, as well as the objects of engineering construction. That is, various engineering facilities built on the ground, underground, or on land, directly or indirectly serving human life, production, military, and scientific research, such as houses, roads, railways, pipelines, tunnels, bridges, canals, dams, ports, power stations, airports, offshore platforms, water supply and drainage, and protective engineering, etc.

[0003] In the prior art, at civil engineering construction sites, building guardrails are installed at the edge of the foundation pit to warn workers or vehicles to drive carefully and avoid safety accidents. However, the existing building guardrails are simply fixed by bolts, and their anti-collision effect is poor. Due to the uncertainty of the construction site, when heavy objects such as stones transported by vehicles fall and roll towards the foundation pit, the building guardrails may not be able to block the heavy objects such as stones, which may cause the heavy objects such as stones to fall into the foundation pit, and may cause harm to the workers working in the foundation pit.

[0026] In this embodiment, bolt 102 is inserted into the four corners of the base plate 101, and the bolt 102 is drilled into the concrete surface by using a tool, and then the support bar 2 is manually rotated around the round rod 1 203 by a certain angle to form a certain angle between the support bar 2 and the support rod 1, and the movable block 205 is rotated around the round rod 204 by a certain angle to keep the bonding plate 206 and the concrete floor in a horizontal state, and then bolt three 207 is inserted into the four corners of the bonding plate 206, and the bolt three 207 is drilled into the concrete floor by using a tool. In this way, when the guardrail body 108 is hit by heavy objects such as stones, a force is applied to the support rod 1 in the direction of the foundation pit. By supporting the support bar 2 to support the support rod 1, part of the force on the support rod 1 can be offset, thereby avoiding the collapse of the building guardrail and ensuring the safety of the construction workers in the foundation pit.
