Will on stair during installed surface masonry material it is necessary to remove provisional protection hurdle, in this period, because stair do not have safeguard procedures,
It is susceptible to workmen's falling accident, be a kind of very big potential safety hazard.
Content of the invention
The present invention be directed to the deficiency existing for prior art, and it is simple, reasonable in design to provide a kind of structure, can drop
Low production cost and improve safety staircase temporary protective railing.
To achieve these goals, the invention provides a kind of staircase temporary protective railing, including pedestal, column, described
Column upper end is connected with handrail, and described column bottom is connected with lever, and described pedestal is connected to each staristep by expansion bolt
The side of free end, described pedestal is locked by bolt with described column, and described handrail is locked by bolt with described column, described vertical
Post and described lever are by bolt connection.
Further, described handrail end bolt locking has expansion link, the described sleeve pipe of stair activity section, handrail, lever
And expansion link is located at same upright projection plane, between adjacent described expansion link, connecting rod is had by bolted splice.
Wherein, described pedestal includes the installing plate being connected with described expansion bolt, and described installing plate is arranged to outside staristep
What side extended has extension rod, and the described extension rod other end is connected with the sleeve pipe for connecting described column.
Described column is square tube, is provided with elongated hole, described elongated hole upper end is communicated with the side of the circular hole with diameter greater than its width
Face constitutes the bar-shaped through hole of match.
Described handrail is opening shape square tube, and end connects to be closed at described expansion link, and the top of described column is stretched into described
Handrail inner chamber is simultaneously locked by bolt.
Described lever is square tube, and both sides correspondence position is provided with strip symmetrical holes, and by described strip symmetrical holes and institute
State the elongated hole bolt connection of column.
The described handrail of the superiors is connected with wall by expansion bolt, specifically, described wall is provided with expansion bolt, institute
State expansion bolt and be connected with connecting plate, described connecting plate is connected with installing pipe, the described telescoping tube of described installing pipe and the top
Socket.
During installation, stamp expansion bolt first, then installation pedestal, the sleeve pipe in order to ensure stair activity section is located at same
Individual upright projection plane, in installing plate and stair intersegmental setting pad；After pedestal installs, column is installed；Length in lever
Insert bolt in bar symmetrical holes, and bolt head is sent into column inner chamber by the circular hole position on column elongated hole top, by bolt
Head hangs over column elongated hole lower end；Put handrail in column top, blending bolt is locked；Expansion link is inserted handrail, then
With bolt, connecting rod is hinged to telescopic rod end.
The beneficial effect of this programme can learn according to the narration of such scheme, structure is simple, reasonable in design, due to setting
In the side of staristep because in paved surface masonry material it is not necessary to remove, thus set up formal guard rail before this when
Phase, protective action can be effectively played it is noted that safety.And all parts is easy to canalization batch production, can accomplish pre-
First produce, take at any time, efficiency of construction can be greatly improved.Simultaneously as this programme is all locked by bolt or bolt connection,
It is easily installed and is easy to remove, utilization can be had enough to meet the need, save material, reduce cost.Because each part will have enough to meet the need utilization, use
In different staristep, and using production model in advance, so cooperation handrail is provided with expansion link to adapt to different buildings
Bench.Between expansion link, connecting rod is set, makes the two ends of handrail have support, by increasing capacitance it is possible to increase the support force of handrail.Sleeve pipe, handrail,
Lever and expansion link are located at same upright projection plane, at utmost make use of the space between staristep, keep away as far as possible
Exempt from the interference to later stage paved surface masonry material, and clean and tidy specification, contribute to the quality control of production scene.Handrail adopts opening
Shape square tube, can adapt to column and arranges in diverse location, with to with without rectification.Lever setting strip symmetrical holes connect spiral shell
Bolt, column arranges the bar-shaped through hole of match and is hung over lever on column by bolt head, be a kind of installing/dismounting fast and easily
Connected mode.
