Background

Civil engineering construction refers to human activities such as construction, maintenance, exploration and the like on the ground or underground in land construction engineering, and almost all human living places, workplaces, traffic facilities and social infrastructure in the society at present are the construction range of civil engineering buildings.

During civil engineering construction, especially important constructor's safety protection, the constructor can carry out the safety action to constructor and explain, for constructor configuration facilities such as safety helmet, emergency support and safety rope, during the construction, constructor can place a plurality of safety barrier at the construction area and carry out personnel vehicle isolation and safety protection, but the weak point that exists has: when stair construction, because the form of stair is the stairstepping structure, there is vertical fall in the tread from top to bottom, when leading to place safety barrier on stair, safety barrier base and tread contact are incomplete, and safety barrier exists puts unstable problem.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a safety barrier is used in civil engineering construction to solve safety barrier and place unstable problem on stair among the prior art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a safety barrier is used in civil engineering construction, includes the end post and installs the intermediate prop between the end post, movable groove has been laid along vertical to end post one side, movable groove's both sides are equipped with the rotary groove, the interpolation of movable groove is equipped with the horizontal pole, the pivot has been installed to the symmetry on the horizontal pole, the rotary shaft rotates connects the rotary groove.

Preferably, the clamping pipes are vertically arranged on two sides of the middle column, a clamping groove is formed in one end of each clamping pipe, one end of each cross rod is inserted into the corresponding clamping groove, penetrating openings are formed in the cross rods, through holes are symmetrically formed in the clamping grooves, bolts penetrate through the penetrating openings and the through holes, and nuts are connected to one sections of the bolts penetrating through the clamping pipes through threads.

Preferably, the lower ends of the middle column and the end column are provided with bases, and screw holes are formed in the bases.

Preferably, the clamping groove is of a U-shaped groove structure.

Preferably, the base is of a cuboid structure.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model provides a safety barrier for civil engineering construction puts on stair through the end post with both sides, puts the interlude in the centre, and the pivot of horizontal pole one end makes whole guardrail steadily put on stair at the rotary trough internal rotation, and reuse inflation screw in screw hole squeezes into the fixed orifices of beating in advance on stair, can make safety barrier place the avris at stair firmly.

The utility model provides a safety barrier for civil engineering construction when demolising the guardrail, only need to back out the bolt with the nut, take out the bolt and wear mouth and through-hole, take out the horizontal pole and press from both sides the groove, can accomplish dismantling of guardrail, the transportation and the reuse of the guardrail of also being convenient for simultaneously.
