Abstract
The utility model discloses a staircase protective handrail which is used for temporary protection of a staircase on a construction site. The staircase protective handrail comprises a straight pipe and an elbow, wherein the straight pipe is of a straight circular steel pipe, and the straight pipe comprises a vertical pipe, a short pipe and a long pipe used as the handrail; the elbow is of a right-angle bent circular pipe, the outer diameter of the elbow is smaller than the inner diameter of the straight pipe, and the port of the elbow can be inserted into the straight pipe; and the vertical pipe is connected with the short pipe, the short pipe is connected with the elbow, and the elbow is connected with the long pipe. The staircase protective handrail disclosed by the utility model adopts a structure which can be assembled and disassembled, the mounting is convenient and fast, special members are fewer, steel pipes of an existing scaffold on the site can be directly utilized for using local materials, and the safety is good.
Description
[technical field]
The utility model relates to the interim protective equipment of building, relates in particular to a kind of stair guard rail.
[background technology]
The interim guardrail of the stair in building operations building site is the pith of site safety facility.Traditional stair railing is to adopt scaffolding steel pipe and fastener to be built into easy handrail mostly, builds complicacy, and poor stability was both inconvenient, also dangerous.
Existing existing assembling or the special-purpose interim railing of modular stair of adopting, its main member needs special the making, and it is not very convenient using.
[summary of the invention]
It is less that the technical problem that the utility model will solve provides a kind of member, stair guard rail safe in utilization.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is that a kind of stair guard rail is used for the interim protection of building site stair, comprises straight tube and elbow; Straight tube is the round steel pipe of straight shape, and straight tube comprises standpipe, short tube and long tube; Elbow is a right angle bending pipe, and the external diameter of elbow is less than the internal diameter of straight tube, and the port of elbow can insert in the straight tube; Standpipe is connected with short tube, and short tube is connected with elbow, and elbow is connected with long tube.
As preferably, standpipe is connected through fastener with short tube.
As preferably, standpipe and short tube welding.
As preferably, short tube and elbow are affixed through tight fixed bolt.
As preferably, elbow and long tube are affixed through tight fixed bolt.
As preferably, the external diameter of elbow is 32mm.
As preferably, the straight tube external diameter is 48mm.
As preferably, straight tube is a scaffolding steel pipe.
As preferably, stair railing is made as twice up and down; The upper track railing laterally arranges with following road railing.
The beneficial effect of the utility model is:
Employing can be rolled over assembling structure, and it is convenient to install, and autocratic member is less, directly utilizes the existing scaffolding steel pipe in building site, gathers materials on the spot, and safety is good.
[description of drawings]
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.
Fig. 1 is the front view of the utility model stair guard rail embodiment 1.
Fig. 2 is the vertical view of the utility model stair guard rail embodiment 1.
Among the figure, 1-standpipe, 2-short tube, elbow under the 3-, the last elbow of 4-, 5-long tube, 6-long tube, 7-tight fixed bolt.
[specific embodiment]
Embodiment 1:
Fig. 1 is a kind of stair guard rail, is used for the interim protection of building site stair, is to be that member is assembled with straight tube and elbow, and is safer for making guardrail, is provided with twice guard rail up and down.
In Fig. 2, straight tube all uses the circular scaffolding steel pipe of external diameter 48mm to process, and is divided into short tube 2, long tube 5 and standpipe 1.Elbow is that external diameter is the circular right-angle elbow pipe of 32mm, and the elbow external diameter is less than the straight tube internal diameter, and the port of elbow can insert in the straight tube.
Welding in the middle of standpipe 1 upper end and the short tube 2; The two ends of short tube 2 are inserted and are gone up elbow 4 and following elbow 3, and fixing with tight fixed bolt 7, and following elbow 3 is connected with the long tube 5 that is used as up railing; Last elbow 4 is connected with the long tube 6 that is used as descending railing, so constitutes the upper track stair railing.The following road railing structure of stair is identical with upper track, and just short tube is welded on the medium position of standpipe 1.The lower end of standpipe 1 is connected through tight fixed bolt with the pre-buried steel pipe mouth of pipe in stair ground.
In the present embodiment, have only elbow to need special the making, all the other only need scaffolding steel pipe is cut out appropriate length, welding and boring, load onto tight fixed bolt, promptly can be used for being assembled into stair railing.Draw materials conveniently, processing capacity is less, directly site construction.
Embodiment 2:
In the present embodiment, standpipe 1 and short tube 2 are connected through fastener, and the short tube of lower floor's railing is connected with standpipe 1 with fastener equally.Other structures are identical with embodiment 1.
Present embodiment need not welding, directly uses fastener, makes process and assemble more quick.
Above content only is to what how the utility model was implemented to be done to give an example and explanation; Rather than the protection domain of restriction the utility model; Under the technician in present technique field described specific embodiment is made various modifications or replenish or adopt similar mode to substitute; Only otherwise depart from the structure of invention or surmount the defined scope of these claims, all should belong to the protection domain of the utility model.
