Detailed Description
The present invention will be further described with reference to the drawings and examples, which should not be construed as a limitation to the present invention.
The embodiment of the utility model provides a: what use during suspension bridge steel truss stiffening girder hoist and mount welding construction faces limit protective structure, as shown in figure 1-3, including side direction open-ended base structure, a plurality of base structure joint is on girder steel panel 8 to fix through fastening bolt 4, base structure top surface welded fastening is provided with 1 vertical pole setting 5, vertical pole setting 5 is provided with 2-3 holes 6 of wearing along its direction of height interval, connects through many wire rope 7 between a plurality of base structures and constitutes whole face limit protective structure. The base structure comprises a long-strip-shaped upper base 1 and a long-strip-shaped lower base 3, one ends of the upper base 1 and the lower base 3 are fixedly connected through a connecting steel plate 2, the upper base 1, the connecting steel plate 2 and the lower base 3 form an Contraband-shaped structure with a lateral opening, and a fastening bolt 4 penetrating through the top and the bottom of the upper base 1 is arranged on the upper base 1.
Two ends of the steel wire rope 7 are connected with rope clamps 9, and the rope clamps 9 are clamped at the penetration holes 6. The tensioned steel wire rope 7 is limited and fixed by using a rope clamp 9.
Go up base 1 and lower base 3 and form with the channel-section steel preparation, vertical pole setting 5 uses the angle steel preparation to form, and convenient for material selection.
This face limit protection architecture, through 2 channel-section steels preparation honest upper base 1 and lower base 3, rethread connecting plate 2 becomes a whole with upper base 1 and the welding of lower base 3, opens two bolt holes at upper base 1 top for penetrate fastening bolt 4. Base structure installs in the reservation notch position department of girder steel top surface during the use, and during base structure's side direction opening was gone into to girder steel panel 8 cards, through fastening bolt 4's fastening effect to utilize the counter-force principle of base 3 channel-section steel down, form counter-force structure, through the fastening bolt 4 at top, exert normal pressure, with the frictional force of base 3 channel-section steel and girder steel panel 8 under the increase bottom, thereby play firm effect. The wire tightener and the rope clamp 9 are used for limiting the steel wire rope 7, so that protection and alternate propulsion are realized.
