Description
Technical field
The utility model belongs to building site protective guard technical field, especially relates to a kind of stair temporary guard rail.
Background technology
At present, on building construction building site, particularly highrise building usually before no knot top inside be cold, and the escape way of large multi-rise building does not all have this design of window, and therefore daylighting is poor.Workman on building site when carrying out operation to the stair on these escape ways or going to more high-rise by these stair, often inside be very dark or light comparatively dim.Provisional protection hurdle usually can be installed in existing building site on the comparatively dim stair of these light, stop some potential safety hazards with this; But this protective guard can only play basic protective action, and they are mostly connected by welding, and installing like this and dismantling all comparatively wastes time and energy; Therefore be necessary to be improved.
Summary of the invention
The purpose of this utility model is the deficiency existed for above-mentioned prior art, provides a kind of stair temporary guard rail, and it has, and structure is simple, easy installation and removal and have the feature of illumination functions.
To achieve these goals, the technical scheme that the utility model adopts is: a kind of stair temporary guard rail, comprises column, and the bottom of column is provided with firm banking; It also comprises guard rail rod and the lock nut of band elbow connecting portion, and described guard rail rod is provided with projection, described column offers through hole, projection sleeve is in through hole; The external surface of described projection is provided with external screw thread, is provided with internal thread in the endoporus of described lock nut, and external screw thread and internal thread are spirally connected mutually; The side face of described guard rail rod scribbles fluorescence coating.
Be provided with two guard rail rods between described two columns, be parallel to each other between two guard rail rods.
Described column and guard rail rod are that plastics are made.
Adopt after said structure, the utility model compared to the prior art advantageously: structure of the present utility model is simple, is spirally connected by the projection on it and lock nut by guard rail rod, allows and installs and dismantle all very convenient; Fluorescence coating on guard rail rod can allow guard rail rod can produce light when dim, makes work convenient and staff can be allowed to understand the critical localisation of stair, eliminating safe hidden trouble.
