Abstract
The invention discloses single upright and double upright connection. The single upright and double upright connection is composed of an upper single upright, right-angle couplers, large cross bars, rotary buckles and lower double uprights, the joints at the top layers of the uprights can use lap joints, the joints at the other parts of the uprights must use butting couplers, the lap length should be larger than or equal to 1 meter when lapping, more than two rotary buckles are used for buckling firmly, the distance between the outer edge of each buckle and the upright end is larger than or equal to 100 millimeters, the distance between each upright joint and the close large cross bar is less than or equal to 1/3 of the step height, the distance between adjacent joints should be larger than 500 millimeters, one of the lower uprights extends to form the upper single upright, and the lower upright should bear 70% of all the load of the upper single upright and a half of the load of the lower upright; the upper single upright is simultaneously lapped with the lower double uprights, a small cross bar supports the upper single upright, and the small cross bar is arranged between the lower double uprights; the lap part is provided with at least three rotary buckles, and the three buckles are firmly connected to reinforce the support force for the large cross bar.
Description
Technical field:
The present invention relates to a kind of scaffold, especially design the connection of a kind of single vertical rod and two vertical rod.
Background technology:
Scaffold building personnel must examine qualified professional scaffolder through existing national standards " special operation workers safety technics is with reference to rule " (GB5036), eligible can be taken appointment with certificate, Safety helmet must be worn to set up personnel, set up ground and must establish security area, necessary team-work when stopping over, prevent down bar to hurt sb.'s feelings, when setting up anti-fall canopy, people must not stand in color steel watt centre, prevents high falling.
Summary of the invention:
Object of the present invention is exactly defect in order to overcome prior art and provides the connection of a kind of single vertical rod and two vertical rod.
To achieve these goals, the technical solution adopted in the present invention is:
The connection of a kind of single vertical rod and two vertical rod, by upper single vertical rod, right-angle coupler, leger, rotary buckle and lower pair of vertical dry composition, the joint of vertical rod is except top layer can adopt lap joint, all the other must adopt carries out butt joint to clasp, lap length during overlap joint should not be less than 1 meter, buckle with being not less than two rotary buckles, the outward flange of fastener is not less than 100mm to rod end distance, the distance of vertical rod joint and close leger should not be greater than walk high by 1/3rd, the height of adjacent joint should be greater than 500mm, upper single vertical rod is formed by the extension of in the vertical rod of bottom, this bar should by bear all upper 70% of single vertical rod load and the half of bottom load consider, upper single vertical rod simultaneously and lower pair of vertical rod overlap, upper single vertical rod is bearing on little cross bar, little cross bar is then placed between lower pair of vertical rod, overlap is no less than three road rotary buckles, three road fasteners immediately, to strengthen leger holding power.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the invention process:
In figure, 1, upper single vertical rod, 2, right-angle coupler, 3, leger, 4, rotary buckle, 5, lower pair of vertical rod.
Detailed description of the invention:
Below in conjunction with accompanying drawing, the present invention is further illustrated.
The connection of a kind of single vertical rod and two vertical rod, by upper single vertical rod (1), right-angle coupler (2), leger (3), rotary buckle (4) and lower pair of vertical dry (5) composition, the joint of vertical rod is except top layer can adopt lap joint, all the other must adopt carries out butt joint to clasp, lap length during overlap joint should not be less than 1 meter, buckle with being not less than two rotary buckles (4), the outward flange of fastener is not less than 100mm to rod end distance, the distance of vertical rod joint and close leger (3) should not be greater than walk high by 1/3rd, the height of adjacent joint should be greater than 500mm, upper single vertical rod (1) is formed by the extension of in the vertical rod of bottom, this bar should by bear all upper 70% of single vertical rod (1) load and the half of bottom load consider, upper single vertical rod (1) simultaneously and lower pair of vertical rod (5) overlap, upper single vertical rod (1) is bearing on little cross bar, little cross bar is then placed between lower pair of vertical rod (5), overlap is no less than three road rotary buckles (4), three road fasteners immediately, to strengthen leger (3) holding power.
