Description
Technical field
The present invention relates to a kind of building operations guard rail, particularly relate to the mounting method that a kind of stair face limit construction protection railing and guard rail.
Background technology
In building operations, carry out operation and all need to carry out security protection facing deathtrap, limit, with preventive works, personnel fall from eminence, cause workman's casualty accident and unnecessary loss.
Usually, facing bound defence rail is field fabrication, measures and faces limit size, then has got steel pipe material, then scene is welded, because the various limit situation of facing is different, it is also different to face bound defence rail size, after a place uses, dismounting also cannot recycle after coming, and remove with gas welding when removing, waste material, wastes man-hour; Meanwhile, the angle of weld ell can not free adjustment, is unsuitable for reusing, re-starts adjustment after only having cutting, even if some railing can free adjustment angle, but complicated structure, cost is high, mounting or dismounting inconvenience; In addition, the length of stair is irregular, and the guard rail for the stair of different length needs separately to make separately, so just easily causes the waste caused because material blocks.
Summary of the invention
For the deficiencies in the prior art, the object of the invention is in order to solve stair in prior art face limit construction protection railing mounting or dismounting inconvenience, corner elbow angle can not free adjustment, railing length is non-adjustable and can not adapt to the defects such as the stair of different length, and provide a kind of and install and remove conveniently, the angle of corner elbow free adjustment, the stair with certain length adjustability can face limit construction protection railing and mounting method.
In order to solve the problems of the technologies described above, present invention employs following technical scheme:
A kind of stair face limit construction protection railing, comprise that tree root faces limit vertical rod spaced apart along stair, the cross tube that is placed in all vertical rod tops and the sheer pole be connected in the middle part of all vertical rods, described cross tube comprises 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 the first half and the latter half, the latter half is connected to the top of vertical rod, the side of the first half connects in the latter half rotationally, and the opposite side of the first 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 the first fixed head upwards extended, and the bottom of the latter half of described clip has the second fixed head to downward-extension, is coupled together between described first fixed head and the second fixed head by screw bolt and nut.
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 advantage that stair of the present invention face limit construction protection railing is:
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), be bolted connection between various piece, and mounting or dismounting are convenient; Meanwhile, the railing that scene is welded compared by this knockdown guard rail, and each several part can adopt batch production to make, and can avoid the waste caused because material blocks, and this knockdown guard rail also has the advantage of conveniently leasing.
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 arrange because elbow adopts to be separated, unclamping bolt can carry out free adjustment to the angle of elbow.
Straight cross bar of the present invention is connected with adopting sleeve pipe between elbow, and unclamping bolt can regulate the length of both intersection, so just makes whole cross tube have certain length adjustability, can adapt to the stair of different length.
Stair face a construction method for limit construction protection railing, comprise the steps:
1) vertical rod is installed: the installation site first determining 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 installation site by the base of vertical rod, and makes vertical rod firm without rocking;
2) cross tube is installed: first according to the length of stair, select the straight cross bar of appropriate length, then by elbow grafting or the end being 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: the spacing according to vertical rod selects adaptive sheer pole, with bolt, sheer pole is fixed on 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 paint at the external coating of staircase protective handrail.
The mounting method advantage that stair of the present invention face limit construction protection railing is:
This method is for the railing that scene is welded, greatly can save material, reduce costs, remarkable in economical benefits, and relative to the mounting method of traditional defense railing, this method technique is simpler, and install and remove more convenient, safety is higher, cost is cheaper, and can reusing, achieving preferably from studying to the conversion of applying, meet builing industry to tool, standardized development trend.
