6, support meanss 6 include first plate above top flange plate 50,60, two the second plates located at the lower section of top flange plate 50
61 and two the 3rd plates 62 for being respectively arranged on the both sides of top flange plate 50, and two the second plates 61 are respectively positioned at the first plate 60
Both ends, the second plate 61 are sequentially connected with the 3rd plate 62 and the first plate 60 from bottom to up, in the first plate 60, the second plate 61 and the 3rd plate 62
Gusset is closed to form an accommodating chamber, and top flange plate 50 is fastened in accommodating chamber, so as to form left-hand thread structure, support meanss 6 are firm
On top flange plate 50.Preferably, the 3rd plate 62 is identical with the thickness of top flange plate 50, and is be arranged in parallel with top flange plate 50,
So that left-hand thread best results.
In the present embodiment, guide rail 10 is i shaped steel, bottom and the bolt connection of the first plate 60, will be led by support meanss 6
Rail 10 on top flange plate 50, so as to avoid the direct bump contact steel beam surface of guide rail 10, causes to damage girder steel securely
Finish paint, and avoid clashing with structures such as longeron WELDING STUDSs.
When using above-mentioned extension type construction platform, support body 2 is first slid into the correct position of guide rail 10, then used
Sleeper etc. is retained, and then expansion bracket 30, which slides, extend out to the left and right sides of support body 2, then by elevating mechanism 32 by operation horizontal
Platform 31 is promoted to proper height, after the completion of use, can reduce the height of job platform 31, is located at the expansion bracket 30
It is interior, the counter motion again of expansion bracket 30, bounce back in support body 2.
Job platform 31 can move along the direction of guide rail 10 in the extension type construction platform of the present embodiment, and can along perpendicular to
The direction telescopic moving of guide rail 10 so that the boundary of works area of operating personnel is very wide, without repeating to hang or dismantle, need to only move i.e.
Bolt weldering can be carried out to the gusset plate that diverse location is distributed, efficiency of construction is high, uses manpower and material resources sparingly, moreover, with it is common assembled up and down
Truss structure compare, the job platform of the application is extended on the outside of support body so that operating space is big, is easy to construction operation.
The present invention is not limited to the above-described embodiments, for those skilled in the art, is not departing from
On the premise of the principle of the invention, some improvements and modifications can also be made, these improvements and modifications are also considered as the protection of the present invention
Within the scope of.The content not being described in detail in this specification belongs to prior art known to professional and technical personnel in the field.
