Description

Temporary shaping protective railing for stairwell Technical Field The utility model relates to the technical field of constructional engineering, in particular to a temporary shaping protective railing for a stairwell. Background In the engineering project construction process, the temporary protection of the stairwell is indispensable, and by arranging the temporary protection railing, personnel can be effectively prevented from falling from the stairwell due to accidental foot loss or slipping, and the stair is particularly suitable for high-altitude protection of construction or unfinished areas. Through setting up the stair room and protecting the dangerous area such as railing division stair entrance to a cave, face limit, avoid irrelevant personnel mistake to go into and cause the potential safety hazard. The traditional temporary guard rail for the stairwell is usually formed by erecting steel pipes and fasteners. The steel pipe and the fastener are large in usage amount, long in time consumption and low in efficiency, and the rod piece of the temporary protection railing of the constructed stairwell is exposed out of the upright post, so that collision injury of construction operators is easily caused. In addition, the fastener is bulky when railing and stand are connected, and the stand is difficult to adjust the position and advances the reliable connection with the railing when the distance is nearer with the railing. In addition, the temporary guard rail erected by the steel pipe and the fastener may not meet the width requirement of the stairwell neutral gear. Disclosure of utility model The utility model aims to provide a temporary finalized protective railing for a stairwell, which solves the problems that the temporary protective railing for the stairwell erected by steel pipe fasteners has potential safety hazards of collision injury, the construction efficiency is low, and the connection volume of a column and the railing through the fasteners is large due to the large volume of the steel pipe fasteners, so that reliable connection is difficult to adjust. In order to solve the technical problems, the temporary finalized protective railing for the stairwell comprises two upright posts vertically arranged on floor slabs at the upper end and the lower end of the stairwell along the same straight line at the adjacent edge of the stairwell, at least two connecting steel pipes parallel to the gradient of the stairwell are arranged on opposite vertical faces of the two upright posts through adjustable connecting pieces, a railing is sleeved between the two upright posts through each connecting steel pipe, and the connecting steel pipes are connected with the railing through locking pieces. Furthermore, the adjustable connecting piece comprises a connecting nut fixedly arranged on the upright post, a connecting screw rod fixedly arranged on the connecting steel pipe, the connecting steel pipe is connected to the connecting nut through the connecting screw rod in a threaded manner, the connecting screw rod can extend into the upright post through the connecting nut, and a hole communicated with the connecting nut is formed in the corresponding upright post. Furthermore, the temporary finalized protective railing for the stairwell provided by the utility model has the advantages that the adjustable connecting piece comprises the internal threaded hole fixedly arranged on the upright post, the connecting screw rod is fixedly arranged on the connecting steel pipe, and the connecting steel pipe is in threaded connection with the internal threaded hole through the connecting screw rod. Furthermore, the temporary finalized protective railing for the stairwell provided by the utility model comprises the locking nut welded on the connecting steel pipe, wherein the locking nut is in threaded connection with the locking screw rod, and the locking screw rod passes through the connecting steel pipe to be tightly propped up or in threaded connection with the railing. Furthermore, the temporary finalized protective railing for the stairwell is characterized in that the connecting steel pipe is a round pipe, the railing is a round pipe, and the railing is positioned in the connecting steel pipe.
