Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of building construction, and in particular relates to a temporary protective railing for stairs. Background Art
[0002] The guardrail is a safety facility on the bridge construction, which plays the role of separation and guidance. In the construction process of some corridors, since the stairs are still in the construction stage, the guardrail has not been installed on the edge of the stairs. In order to save costs, the existing guardrail is only equipped with one or two layers of guardrails on the side of the stairs as protection. However, during the construction of the floor, debris or sundries often fall from the building. After falling from the gap of the stairs, it will not only damage the concrete floor, but also pose a certain threat to the safety of the construction workers. Utility Model Content
[0003] The utility model aims to provide a temporary protective railing for preventing falling objects from falling from the gap between stairs during construction.
[0004] A temporary stair guardrail is arranged on one side of the stairs, characterized in that it comprises a supporting column, a connecting elbow, a guard bar, a first vertical baffle, an oblique baffle and a second vertical baffle, a mounting base is arranged at the bottom of the supporting column, the mounting base of the supporting column is respectively fixed to the upper and lower ends of the stairs by bolts, the upper, middle and lower parts of the supporting column are respectively symmetrically provided with horizontal sleeves, one end of the connecting elbow is inserted into the sleeve and fixed, the other end of the connecting elbow is inserted into the guard bar and fixed, so that the two ends of the guard bar are respectively connected to the supporting columns arranged on the upper and lower layers of the stairs, and form upper, middle and lower guard bars; a first vertical baffle is arranged on a side of the stairs close to the lower guard bar, an oblique baffle is arranged along the inclination direction of the lower guard bar, the width of the oblique baffle is consistent with the center distance between two adjacent lower guard bars, the first vertical baffle and the oblique baffle are perpendicular to each other, and are respectively fixed to the same lower guard bar by clamps; a second vertical baffle is fixed on a side of the oblique baffle away from the lower guard bar along the inclination direction of the oblique baffle, and the second vertical baffle is always perpendicular to the oblique baffle.
[0005] Furthermore, a grid-shaped anti-slip layer is provided on the surfaces of the first vertical baffle, the second vertical baffle and the oblique baffle.
[0006] Furthermore, corresponding screw holes are respectively provided at the outer end of the sleeve, the two ends of the connecting elbow and the two ends of the protective rod. The two ends of the connecting elbow are respectively inserted into the sleeve and the protective rod, and are fixed by bolts at the corresponding screw hole positions.
[0007] Furthermore, the number of screw holes provided on the sleeve, the connecting elbow and the protective rod is not less than two.
[0008] The beneficial effect of the utility model is that the protective rod is connected by the support column and the connecting elbow, which not only ensures the reliable connection of the structure, but also can be disassembled and bottled according to the needs, and can be reused. At the same time, the installation of the oblique baffle and the vertical baffle not only prevents the falling objects on the upper floor from falling from the gap of the stairs, but also prevents the debris on the stairs from falling from the side, which not only protects the building floor, but also ensures the safety of the construction workers.

[0014] Embodiment 1: A temporary stair guardrail is arranged on one side of the stairs, comprising a support column 1, a connecting elbow 2, a guard rod 3, a first vertical baffle 4, an oblique baffle 5 and a second vertical baffle 6. A mounting base 11 is arranged at the bottom of the support column 1, and the mounting base 11 of the support column 1 is respectively fixed to the upper and lower ends of the stairs by bolts. Horizontal sleeves 12 are symmetrically arranged on the upper, middle and lower parts of the support column 1, and two screw holes corresponding to the positions are respectively provided at the outer end of the sleeve 12, the two ends of the connecting elbow 2 and the two ends of the guard rod 3; one end of the connecting elbow 2 is inserted into the sleeve 12, aligned with the positions of the two screw holes and fixed by bolts, and the other end of the connecting elbow 2 is inserted into the guard rod, aligned with the positions of the two screw holes and fixed by bolts, and finally the two ends of the guard rod 3 are respectively connected to the support columns 1 arranged on the upper and lower floors of the stairs to form upper, middle and lower guard rods 3. A first vertical baffle 4 is arranged on the side of the staircase close to the lower guard bar 3, and a diagonal baffle 5 is arranged along the inclination direction of the lower guard bar 3. The width of the diagonal baffle 5 is consistent with the center distance between two adjacent lower guard bars 3. The first vertical baffle 4 and the diagonal baffle 5 are perpendicular to each other and are respectively fixed to the same lower guard bar 3 by clamps; a second vertical baffle 6 is fixed along the inclination direction of the diagonal baffle 5 on the side of the diagonal baffle 5 away from the lower guard bar 3, and the second vertical baffle 6 is always perpendicular to the diagonal baffle 5.
