Tool-type stair guard rail

Technical field

The utility model relates to the safety device that a kind of building site is used, and is especially building the stair guard rail that uses on the building.

Background technology

Traditional stair guard rail generally adopts steel tube fastener to set up and forms, and steel using amount is big, and standpipe just differs, inclined tube length difference is added fastener, is not that to trip be exactly the hand of stumbling, often the someone bumps to knee, and common steel pipe and fastener are often removed by some workmans and diverted to other purpose.In order to address these problems, be badly in need of designing and developing a kind of novel stair and face the frontier defense guard rail rod, not only elegant in appearance, and also very practical.

Summary of the invention

According to background technology, the purpose of this utility model is to avoid above-mentioned deficiency, provide a kind of by column, cross bar, elbow is formed, cross bar length can be regulated in installation process, and column adopts the rotatable elbow that adapts to the differing tilt angles stair, and its structure and type of attachment satisfy the tool-type stair guard rail that the simple or fast quick-detach of assembling requires.

To achieve these goals, the utility model is achieved through the following technical solutions:

A kind of tool-type stair guard rail, mainly by off column (1), receive and run column (2), middle standing pillar (3), return and run column (4) and cross bar (5) composition, wherein: off column (1) runs column (2) with receipts and has identical form of structure, the shaft of column is provided with two unidirectional rotatable elbows (11), return the shaft that runs column (4) and be provided with two two-way rotatable elbows (41), two T type through hole steering knuckles (31) are set on the shaft of middle standing pillar (3), be sleeved on the cross bar (5) that constitutes adjustable length together jointly by large diameter cross bar (51) and little external diameter cross bar (52), can both fixed by hexagon socket head cap screw (54) and hold-down nut (55) between its two; Unidirectional rotatable elbow (11) and two-way rotatable elbow (41) on cross bar (5) and the column shaft, can be connected with the buckle (57) that the cloudy snap-fitting of turning gland (12) is formed by the cross bar sun snap-fitting (53) of cross bar (5), cross bar (5) is locked with T type through hole steering knuckle (31) the employing soket head cap screw (56) on the column shaft, head of screw adopts anti-dismounting nut form, and column shaft and structural plane adopt expansion bolt (62) to carry out structure by steel plate (61) and fix.

Owing to adopted technique scheme, the utlity model has following advantage and effect:

1, design of the present utility model meets the related content of the plant equipment structural reliability design main points in the safety production technique, comprises that the reliability of anti-environmental design, simplification and standardized designs, raising joint portion, structural safety design, are provided with safety device etc.

2, the utility model has been realized tool and regularization, can be used in the protection of various stair in the housing construction.

3, cross bar adjustable length of the present utility model, elbow is rotatable, to adapt to different length, the protection of different angles stair bench;

4, the utility model structural element has adopted and has been different from the general pin hand of common buildings steel pipe, can use simple special tool to carry out assembly and disassembly, convenient transportation and storage.

5 the utility model adopt buckle to connect aspect the node connection, and fixedly the aspect adopts bolt, and is simple in structure, cheap, and working service and repairing are simple and easy.

6, the utility model is saved material usage, helps environmental protection and energy saving.

The specific embodiment

By Fig. 1 to Fig. 5 illustrate, a kind of tool-type stair guard rail, mainly by off column 1, receive and run column 2, middle standing pillar 3, return and run column 4 and cross bar 5 compositions, wherein: off column 1 runs column 2 with receipts and has identical form of structure, the shaft of column is provided with two unidirectional rotatable elbows 11, return the shaft that runs column 4 and be provided with two two-way rotatable elbows 41, two T type through hole steering knuckles 31 are set on the shaft of middle standing pillar 3, are sleeved on the cross bar 5 that constitutes adjustable length together jointly, can both be fixed by hexagon socket head cap screw 54 and hold-down nut 55 between its two by large diameter cross bar 51 and little external diameter cross bar 52; Unidirectional rotatable elbow 11 and two-way rotatable elbow 41 on cross bar 5 and the column shaft, can be connected with the buckle 57 that the cloudy snap-fitting 12 of turning gland is formed by the cross bar sun snap-fitting 53 of cross bar 5, cross bar 5 is locked with the T type through hole steering knuckle 31 employing soket head cap screws 56 on the column shaft, head of screw adopts anti-dismounting nut form, and column shaft and structural plane adopt expansion bolt 62 to carry out structure by steel plate 61 and fix.

Other knows, considers that field worker quality is relatively low, and form of structure of the present utility model can not be too complicated; Consider on-the-spot quick and easy for installationly, reduce the use of fixedly connected modes such as screw as far as possible, adopt cloudy (sun) buckle to be connected between cross bar and the column; Consider the length of stair bench, the difference at angle of inclination, cross bar has partly adopted the design that can stretch, the rotatable design of elbow part; Consider to prevent that the workman from will dismantling railing and diverting to other purpose, adopted the steel pipe different, adopted soket head cap screw fixing of cross bar in addition, designed anti-dismounting protective cap as the main material of making railing with on-the-spot scaffolding steel pipe specification; Consider the steadiness of stair railing, stair railing and staircase structure face adopt expansion bolt to fix.

During installation, at first assemble column and cross bar on the staristep that will install, be put into the installation site in advance, regulate the spacing of middle standing pillar, both guaranteed that the column spacing was not more than 2 meters, make between the column spacing about equally again, railing is stressed even and attractive in appearance like this.

After adjusting the installation site, through the bolt hole perforating on the staircase structure face on the column footing fixation steel plate 61, fastening expansion bolt 62 is installed with Churn drill.

Adjust the installation site of soket head cap screw 56 at last, guarantee, in order to avoid influence the overall appearance effect at downside.Fastening soket head cap screw 56 installs.

By Fig. 2 cloudy snap-fitting 12 is shown, wherein is provided with cloudy buckle groove 121.

By Fig. 3 positive snap-fitting 53 is shown, it is provided with joint projection dop 531.

By Fig. 4 the locking form of cross bar 5 is shown, wherein adopts soket head cap screw 56 lockings, ailhead adopts anti-dismounting nut form.

By Fig. 5 fixed structure form between cross bar is shown, wherein puts hold-down nut 55, be screwed into hexagon socket head cap screw 54 both are fixed in the weldering of the end of large diameter cross bar 51.
