[specific embodiment]
Below in conjunction with accompanying drawing the present invention is described in further detail.
Fig. 1 is dismountable bracket 1 stereogram of the present invention.The dismountable bracket 1 of the present invention comprises standing part 2 and support section 3.And described reassembling type bracket is an all-welded structure.Standing part 2 comprises stationary plane 21 and supporting surface 22.Supporting surface 22 is towards concrete, and the angle of supporting surface 22 is corresponding with the concrete external surface, makes supporting surface 22 stable being held on the concrete, strengthens dismountable bracket 1 resistance to overturning.Stationary plane 21 is a vertical plane, which is provided with through hole 23, and described through hole 23 passes stationary plane 21 and supporting surface 22.
Support section 3 links together with the bottom of standing part 2, and described support section 3 is a polygon that outwards protrudes.It is provided with the bottom surface 32 and an end face 31 that tilts of a level.Support section 3 can stretch in the concrete, works to support whole dismountable bracket 1.The bottom surface 32 of level plays a supportive role simultaneously, and prior art by stretching into the support section 3 in the concrete, makes that the load of the dismountable bracket 1 of the present invention is bigger by being welded to connect bracket relatively.
Please be simultaneously with reference to Fig. 2, the through hole 23 on the stationary plane 21 is one group, and through hole 23 is horizontal.
Please also refer to Fig. 1-3 below.This dismountable bracket 1 also is provided with fastening devices, and described fastening devices comprises fixed bar 4, pad 41 and nut 42.Described fixed bar 4 is a finish rolling deformed bar.Pad 41 pads that described fixed bar 4 two ends are equipped with pad 41 and nut 42, one ends are located on the stationary plane 21, are fixed on the stationary plane 21 by the end of nut 42 with fixed bar 4.Simultaneously, the other end of fixed bar 4 also is fixed on the concrete medial surface by pad 41 and nut 42.Because the dismountable bracket 1 of the present invention is fixed on the concrete by fixed bar 4 and nut 42, not only easy for installation, it can be pulled down repeated use after using, pull down the back simultaneously the mud jacking reparation is carried out in the hole that stays on the concrete, it is attractive in appearance to avoid destroying concrete.
