Description
Technical field
The present invention relates to a kind of construction guard rail, particularly relate to a kind of stair and face limit construction protection railing and the installation method of guard rail.
Background technology
In construction, carrying out operation be required for carrying out security protection facing deathtrap, limit, with prevention work, personnel fall from eminence, cause workman's casualty accident and unnecessary loss.
Generally, facing bound defence rail is field fabrication, measures and faces limit size, then has taken steel pipe material, then scene is welded, owing to various limit situations of facing are different, face bound defence rail size the most different, after using at one, dismounting also cannot recycle after coming, and remove with gas welding when removing, waste material, waste man-hour;Meanwhile, the angle of weld ell can not freely regulate, and is unsuitable for reusing, and only re-starts regulation after cutting, even if some railing can freely regulate angle, but complicated structure, cost is high, mounting or dismounting inconvenience;It addition, the length of stair is irregular, the guard rail for the stair of different length needs individually to be fabricated separately, and thus easily causes the waste caused because material blocks.
Summary of the invention
For the deficiencies in the prior art, the invention aims to solve that stair in prior art face limit construction protection railing mounting or dismounting inconvenience, the angle of corner elbow can not freely regulate, railing length is non-adjustable and does not adapt to the defects such as the stair of different length, and provide a kind of be convenient to mount and dismount, the angle of corner elbow can freely regulate, the stair with certain length adjustability face limit construction protection railing and installation method.
In order to solve above-mentioned technical problem, present invention employs following technical scheme:
A kind of stair face limit construction protection railing, face limit vertical rod spaced apart, the cross tube being placed in all vertical rod tops including tree root along stair and be connected to the sheer pole in the middle part of all vertical rods, described cross tube includes straight cross bar and is connected to the elbow of straight crossbar end, described elbow grafting or be socketed in the end of straight cross bar, and both superposition section are tightened by bolts fixing.
Preferably, the top of described vertical rod is provided with clip, described clip is made up of top half and the latter half, the latter half is connected to the top of vertical rod, the side of top half is rotatably coupled on the latter half, and the opposite side of top half is connected on the lower half by screw bolt and nut thus is fixedly clamped by cross tube.
Preferably, the top of described vertical rod has upwardly extending first fixed plate, and the bottom of the latter half of described clip has the second fixed plate downwardly extended, and is coupled together by screw bolt and nut between described first fixed plate and the second fixed plate.
Preferably, described sheer pole is band steel, and sheer pole is bolted in all vertical rods.
Preferably, described cross tube is parallel with sheer pole.
Preferably, the bottom of described vertical rod is provided with base, and described base is fixed on stair by swell fixture.
The stair of the present invention face the advantage of limit construction protection railing and are:
Construction protection railing is decomposed into four parts by the present invention: vertical rod, cross tube (straight cross bar and elbow), sheer pole (band steel), is bolted connection, is convenient to mount and dismount between various piece;Meanwhile, for the railing that scene is welded compared by this knockdown guard rail, each several part can use batch production to make, and can avoid the waste caused because material blocks, and this knockdown guard rail also has the advantage conveniently leased.
The cross tube of the present invention is made up of straight cross bar and elbow two parts, and elbow is bolted the end at straight cross bar, and owing to elbow uses separately positioned, unclamping bolt can carry out free regulation to the angle of elbow.
Using telescopic joint between straight cross bar and the elbow of the present invention, unclamping bolt can be adjusted the length of both intersection, thus makes whole cross tube have certain length adjustability, it is possible to adapt to the stair of different length.
A kind of stair face the construction method of limit construction protection railing, comprise the steps:
1) vertical rod is installed: first determine the installation site of each vertical rod, then hole in installation site according to bolt hole reserved on vertical rod base, cleaning eye sediment, vertical rod is in place, expansion bolt is installed, fastening expansion bolt, is fixed on the base of vertical rod installation site, and makes vertical rod firm without rocking;
2) cross tube is installed: first according to the length of stair, selecting the straight cross bar of appropriate length, then by elbow grafting or the end that is socketed in straight cross bar, both superposition section are tightened by bolts fixing, obtain the cross tube with elbow, finally cross tube is fixed on the top of all vertical rods;
3) sheer pole is installed: select adaptive sheer pole according to the spacing of vertical rod, sheer pole is fixed on bolt the middle part of all vertical rods.
Preferably, construction method also comprises the steps: 4) brushing: carry out cleaning rust cleaning to installing the staircase protective handrail fixed, and at the external coating paint of staircase protective handrail.
Stair of the present invention face the installation method advantage of limit construction protection railing and are:
This method is for the railing that scene is welded, material can be greatly saved, reduce cost, remarkable in economical benefits, and the installation method relative to traditional defense railing, this method technique is simpler, and mounting or dismounting are more convenient, and safety is higher, cost is less expensive, and can reuse, preferably achieve from studying to the conversion applied, meet building industry to tool, standardized development trend.
Accompanying drawing explanation
