Description

A kind of stair railing of angle adjustable

Technical field

This utility model is related to technical field of building construction and in particular to a kind of stair railing of angle adjustable.

Background technology

In building engineering field, the building class building built, after the construction completing external frame, needs to building Constructed in thing, need the equipment using, material and personnel to need to be carried to high level in work progress, built in building If good stair, but generally require in stair both sides installation guardrail to improve safety.Traditional stair railing is that fixation can not Adjust, that is, be directed to each angle and the stair of length are customized, be transported to job site after fractionation and carry out assembling fixation, Gu After fixed, angle cannot adjust, and the stair railing being used between different engineerings can not be general, and this is by different engineering institutes Using stair angle different with span, and traditional stair railing cannot be carried out adjusting, so can not be general, this be accomplished by often Individual engineering customizes different stair railings, not only relatively costly, and the guardrail that recovery is removed can not reuse, versatility Difference.

Utility model content

This utility model aims to provide a kind of stair railing of angle adjustable, to solve building used in existing building engineering The problem that angular length existing for terraced guardrail cannot adjust, poor universality, customization high cost, recycling rate of waterused are low.

This utility model is achieved by following technical solution：

A kind of stair railing of angle adjustable, including two radicle columns, be provided between two radicle columns some can Nurse hurdle monomer, this is adjustable, and guardrail monomer includes two crossbeams being arranged in parallel, and crossbeam two ends have hinge hole, by hinge hole It is hinged with two longerons, be disposed with the fence of some equi-spaced apart arrangements between two longerons, fence two ends are all by hinge hole With bolt is arranged between two crossbeams.

Described longeron is connected with end column by some connecting bolts.

Each two is adjustable to be provided with, by connecting bolt, the middle part column that height is less than end column between guardrail monomer.

Described end column and middle part column bottom are all fixed on stair by mounting seat.

Between the column top of described end, handrail is installed.

The beneficial effects of the utility model are：

Compared with prior art, the stair railing of the angle adjustable that this utility model provides, will install between the column of end Fence be designed to bolted adjustable tetragon, compared to traditional guardrail being welded and fixed formula, this utility model energy Angle according to different stair and span are adjusted, you can be simultaneously suitable for the use requirement of multiple difference engineerings, compare In traditional stair railing, this utility model has the advantages that structure is simple, low cost of manufacture, simple operation, highly versatile, and Can also be used repeatedly, can effectively reduce construction investment cost.

Specific embodiment

Below in conjunction with accompanying drawing, the technical solution of the utility model is described further, but required protection domain is not It is confined to described；

As Figure 1-3, the stair railing of the angle adjustable that this utility model provides, including two radicle columns 6, two Some adjustable guardrail monomers are installed between end column 6, this is adjustable, and guardrail monomer includes two crossbeams being arranged in parallel 1, horizontal Beam 1 two ends have hinge hole 5, are hinged with two longerons 2 by hinge hole 5, are disposed with some equi-spaced apart between two longerons 2 The fence 3 of arrangement, fence 3 two ends are all arranged between two crossbeams 1 by hinge hole 5 and bolt.

Described longeron 2 is connected with end column 6 by some connecting bolts 4.

Each two is adjustable to be provided with, by connecting bolt 4, the middle part column that height is less than end column 6 between guardrail monomer 7.

Described end column 6 and middle part column 7 bottom are all fixed on stair by mounting seat 8.

Described end column 6 is provided with handrail 9 between top.

When conventional horizontal level needs to use, only need to install according to the state shown in Fig. 1-2, need to apply in building When on ladder, first mounting end column 6 and middle part column 7, are then parallel by adjustable guardrail monomer compression as shown in Figure 2 Tetragon, identical with stair angle, then it is arranged between end column 6 and middle part column 7 using connecting bolt 4, all of Adjustable guardrail monomer installs handrail 9 on two end column 6 tops after the completion of being respectively mounted again, finally obtains final product peace as shown in Figure 4 Dress completion statuses.
