Description
Technical Field
The utility model relates to a construction field, concretely relates to face limit entrance to a cave installation rail guard suitable for ground of not making level.
Background
In the building construction process, some face limit entrance to a cave and need protect in the construction stage of difference to ensure constructor safety. The existing guard rail installed at the edge opening is diversified and mainly comprises upright posts, a cross rod, an installation base and a guard net installed between the two upright posts. During assembly, the base is fixed on the ground, the stand column is fixed on the base, and finally the cross rod and the protective net are installed. During assembly, the base is vertical to the upright column, and the base is in a horizontal state. In the practical application process, the ground is not leveled normally, and the problem of inclination exists, and conventional base bottom surface and upper end are the horizontality, and the installation back also can have the slope, and then leads to also being the slope form rather than fixed stand, and whole rail guard is the slope, can not fine support, and the practicality is poor.
Disclosure of Invention
To the not enough of above-mentioned prior art, the utility model aims to solve the technical problem that: if the guardrail can be leveled when the ground is not leveled, the guardrail is simply and conveniently assembled, and the guardrail is installed at the edge opening of the non-leveled ground.
In order to solve the technical problem, the utility model discloses a following technical scheme:
a guard rail for mounting a near-edge opening suitable for an un-leveled ground comprises a plurality of bases arranged at intervals, wherein each base is provided with an upright post, a protective net is hung between every two adjacent upright posts, and the top of each upright post is provided with a cross rod fixedly connected with the upright post; the bottom of each upright post is connected with a flexible leveling pad through a pressure spring, and the flexible leveling pad can deform under the extrusion of external force; a plurality of transverse threaded holes are formed in the circumferential direction of the upper mounting seat at intervals, and the front end of the bolt penetrates through the transverse threaded holes and then abuts against the stand column tightly. Like this, during the assembly, if ground is not leveled, be the slope form, the lower plate of base is the slope form with fixed back in ground, at this moment, inserts the stand in the assembly groove of mount pad to be vertical form with its regulation, the flexible leveling pad of stand bottom warp under the external force extrusion, and hug closely with the assembly groove bottom, and finally, the rethread bolt supports tightly fixedly with the stand lower extreme, maintains the stand under vertical state, and is together fixed with the base. The flexible leveling pads are different in deformation amount when being squeezed by external forces of different sizes, so that effective support can be provided for the lower end of the stand column, the stand column is maintained in a vertical state through the bolts, and meanwhile, after the stand column is tightly fixed through the bolts, the stand column is supported through the base.
Furthermore, a circle of through groove which is transversely arranged is arranged at the lower end of the stand column, a flexible ferrule which extends out of the stand column is further arranged in the through groove, a strip-shaped hole is formed in the position, corresponding to the transverse threaded hole, of the flexible ferrule, and the flexible ferrule can deform under the external force extrusion. Like this, the stand lower extreme logical groove that sets up can make the flexible lasso can not produce the aversion after assembling, and the flexible lasso that sets up can effectively increase the fastening degree between stand lower extreme lateral wall and the last mount pad, makes the stand cover tight fit between the part of last mount pad and assembly groove.
Furthermore, the thickness of the lower end of the flexible ferrule is smaller than that of the upper end of the flexible ferrule, and the outer side of the flexible ferrule is in a slope shape. Thus, the flexible ferrule is more easily inserted when inserted into the fitting hole.
Furthermore, a plurality of bulges are arranged on the inner wall and the outer wall of the flexible ferrule. Therefore, the friction force between the lower end of the upright post and the upper mounting seat can be further increased by the arranged bulge, so that the lower end of the upright post is assembled more tightly.
Furthermore, the stand is the quadrangular, and the assembly groove is square. Like this, the stand is the rectangle to can not rotate after the assembly, fix a position better.
Furthermore, a gap is formed between the protective net and the cross rod, and a plurality of illuminating lamps are arranged on one side, facing the protective net, of the cross rod at intervals. Like this, the light that sets up can play illumination and warning effect night, effectively improves constructor's safety.
Furthermore, a top rod parallel to the cross rod is arranged on the cross rod, and the top rod is connected with the cross rod through a plurality of springs arranged at intervals. Like this, the ejector pin at top can have certain difference in height under the extrusion of spring to when facing the limit entrance to a cave with the rail guard assembly in the elevator, the top has certain deformation space, and is inseparabler with the laminating of entrance to a cave top surface.
Furthermore, an inclined strut is arranged between the cross rod and each upright post. Therefore, the strength of the guard rail can be effectively increased by the aid of the inclined strut.
Furthermore, each upright post is provided with a horizontal bubble. Like this, the horizontal bubble that sets up on the stand can be convenient for installer and have a reference to the column mouting occasionally, ensures that the stand is vertical setting after fixed.
Further, the protective net is a steel wire protective net and is connected with the stand column through a bolt. Thus, the protective net has high strength and can be detached for reuse.
