Description

Rail guard is used in construction in room

Technical Field

The invention belongs to the technical field of house building construction, and particularly relates to a protective fence for house building construction.

Background

The guard rail is generally arranged at the periphery of a building construction site, plays a role in reminding, avoids danger caused by the fact that non-construction personnel enter a construction area by mistake and avoids troubles of damaging the construction site caused by the fact that vehicles enter the construction area by mistake, is usually applied to places with long construction periods such as a building site and the like, and is immovable guard rail is usually adopted, a plurality of foundation bolts are usually used for fixing upright columns on a concrete floor, cross bars are connected between adjacent upright columns through bolts, the cross bars are enclosed into a circle to surround the construction site, and then a valve is arranged at one place of the upright columns for the construction workers and vehicles to pass in and out. However, with the guard rail in the form, people and vehicles can only pass through a gate, and need to be bent when people and vehicles need to enter and exit a construction site from other positions, which is very inconvenient; in addition, the height of the guard rail in the form of the guard rail cannot be adjusted, and the guard rail is possibly too low or too high when the guard rail is used.

Disclosure of Invention

In view of the above, the present invention provides a protective fence for building construction, so as to solve the technical problems that the height of the protective fence for building construction in the prior art cannot be adjusted and people and vehicles cannot conveniently enter a construction site from different positions.
