Abstract
The invention discloses an adjustable fixing assembly of a cantilever beam. The adjustable fixing assembly comprises a U-shaped clamp, a bottom fixing plate, bolt seats, adjusting bolts and pressure plates. Two legs of the U-shaped clamp penetrate reserved holes and are fixed by the aid of the bottom fixing plate, the bolt seats are welded on the inner side of a transverse rod of the U-shaped clamp, each four corresponding adjusting bolts are symmetrical to one another and are connected onto the corresponding bolt seats in a threaded manner, and each pressure plate is hinged to the four corresponding adjusting bolts. The adjustable fixing assembly has the advantages that H-section steel can be fastened by the aid of the adjustable fixing assembly at any time, and accordingly the safety of a discharging platform can be improved.
Description
Technical field
The present invention relates to a kind of discharging platform of building operations, specifically the syndeton of discharging platform oblique pull steel cable.
Background technology
In carrying out high-building construction process, often adopt the mode of encorbelmenting to set up discharging platform, so be provided with Cantilever Beams in respective storey, by fixture, by Cantilever Beams and the fixing mode of body of wall, disperse to bear load, guarantee the safety of discharging platform.When Cantilever Beams is installed, need to be on cast-in-situ floor reserving installation hole, the mode that existing fixed form generally adopts concreting to bury, but because the heavy burden on discharging platform is all changing at any time, under long-time, gap between fixture and Cantilever Beams can increase gradually, causes Cantilever Beams to occur loosening, even makes discharging platform topple over.
Summary of the invention
The present invention to realize object be: a kind of fixture that can be fastening to the adjusting of Cantilever Beams is at any time provided.
For achieving the above object, technical scheme proposed by the invention is: Cantilever Beams is adjustable fixture, comprise U-shaped card and bottom fixed board, two legs of described U-shaped card pass preformed hole and fix by bottom fixed board, also comprise bolt block, adjusting bolt and pressing plate, described bolt block is welded on the cross bar inner side of U-shaped card, and four described adjusting bolts are symmetrical and be threaded and be connected on bolt block, and described pressing plate and four adjusting bolts are hinged.
Cantilever Beams of the present invention is adjustable, and fixture advantage is: between Cantilever Beams and fixture, exist loosening, can make pressing plate that Cantilever Beams is fastening by fastening adjustment bolt, because four adjusting bolts are simultaneously to pressing plate applied thrust, reaction force is distributed in four adjusting bolts, generally there is not vibration frequently in Cantilever Beams, adjusting bolt is difficult for loosening.
Finally, consider that Cantilever Beams and pressing plate contact area are less, on described pressing plate, be provided with rubber layer; Rubber layer and Cantilever Beams contact have increased the frictional force between convex surface.
Accompanying drawing explanation
Fig. 1 is the structural representation of the adjustable fixture of Cantilever Beams mentioned of the embodiment of the present invention.
Fig. 2 is the top view of Fig. 1.
The specific embodiment
The adjustable fixture of Cantilever Beams as depicted in figs. 1 and 2, comprise U-shaped card 2 and bottom fixed board 6, two legs of U-shaped card 2 are through preformed hole fixing by bottom fixed board 6, also comprise bolt block 3, adjusting bolt 4 and pressing plate 5, bolt block 3 is welded on the cross bar inner side of U-shaped card 2, four adjusting bolts 4 are symmetrical and be threaded on bolt block 3, and pressing plate 5 and four adjusting bolts 4 are hinged.
Between Cantilever Beams 1 and U-shaped card 2, exist loosening, can fastening adjustment bolt 4, adjusting bolt band dynamic pressure plate 5, compress gradually Cantilever Beams 1, because four adjusting bolts 4 are simultaneously to pressing plate 5 applied thrusts, Cantilever Beams 1 reaction force can be distributed in four adjusting bolts 4, because Cantilever Beams does not exist vibration frequently, adjusting bolt is difficult for loosening.Consider that Cantilever Beams 1 and pressing plate 5 contacts area are less, on pressing plate 5, be provided with rubber layer; Rubber layer and Cantilever Beams contact have increased the frictional force between them.
Claims (2)
1. the adjustable fixture of Cantilever Beams, comprise U-shaped card and bottom fixed board, two legs of described U-shaped card pass preformed hole and fix by bottom fixed board, it is characterized in that: also comprise bolt block, adjusting bolt and pressing plate, described bolt block is welded on the cross bar inner side of U-shaped card, four described adjusting bolts are symmetrical and be threaded and be connected on bolt block, and described pressing plate and four adjusting bolts are hinged.
2. the adjustable fixture of Cantilever Beams according to claim 1, is characterized in that: on described pressing plate, be provided with rubber layer.
