Support installing part comprises the first plate body and the second plate body; First plate body and the second plate body are rectangular plate body; First plate body is horizontally disposed with; Second plate body is vertically arranged; First plate body is integrally connected with the lower end of the second plate body is vertical by its rear end; First plate body is provided with the first erection bolt hole of row's up/down perforation; Second plate body is provided with before and after a row to the second through erection bolt hole;
Above-mentioned anchor ear is connected by connecting bolt with support installing part.
Further scheme is: the first double team plate, second of above-mentioned anchor ear sandwiches plate, the first junction plate is the width band steel plate identical with thickness with the second junction plate.
Further scheme is: it is miter angle that first of above-mentioned anchor ear sandwiches plate and second angle sandwiched between plate.
Further scheme is: the second junction plate of above-mentioned anchor ear and second angle sandwiched between plate is 135 degree of angles.
Further scheme also has: the material of above-mentioned support installing part is angle steel.
The utility model has positive effect: (1) angle steel tower bracket fixing device of the present utility model, and structure is simple, cost is lower, easy for installation.(2) angle steel tower bracket fixing device of the present utility model, adopts batch production prefabricated, and size is unified, easily expansion, intensity are high, not yielding.(3) angle steel tower bracket fixing device of the present utility model, it in use, only needing assembly to be bolted is fixed on the tower material of angle steel tower, bolt mounting bracket can be used on this device, without the need to resemble in prior art need to change the tower material of existing angle steel tower or on the tower material of angle steel tower perforate with mounting bracket, thus both time saving and energy saving, and construction safety can also be ensured.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
(embodiment 1)
See Fig. 1 to Fig. 3, the angle steel tower bracket fixing device of the present embodiment, form primarily of anchor ear 1, support installing part 2 and connecting bolt 3.
Anchor ear 1 sandwiches plate 11, second primarily of first and sandwiches plate 12, first junction plate 13 and the second junction plate 14 one composition.First sandwiches plate 11, second sandwiches plate 12, first junction plate 13 and the second junction plate 14 and is width, band steel plate that thickness is identical; First sandwiches plate 11 is vertically arranged; Second sandwiches plate 12 inclined upward setting left; First sandwiches the curved one in lower end that the lower end and second of plate 11 sandwiches plate 12 is connected, and preferred miter angle in the first double team plate 11 and second sandwiches between plate 12 angle the present embodiment; First junction plate 13 and the second junction plate 14 are all horizontally disposed with; The curved one in upper end that first junction plate 13 sandwiches plate 11 by its left end and first is connected; First junction plate 13 is provided with the first bolt hole 13-1 of up/down perforation; The curved one in upper end that second junction plate 14 sandwiches plate 12 by its right-hand member and second is connected; And preferred 135 degree of angles in the second junction plate 14 and second sandwiches between plate 12 angle the present embodiment; Second junction plate 14 is provided with the second bolt hole 14-1 of up/down perforation.
Support installing part 2 is primarily of the first plate body 21 and the second plate body 22 one composition; First plate body 21 and the second plate body 22 are rectangular plate body; First plate body 21 is horizontally disposed with; Second plate body 22 is vertically arranged; First plate body 21 is integrally connected with the lower end of the second plate body 22 is vertical by its rear end; First plate body 21 is provided with the first erection bolt hole 21-1 of row's up/down perforation; Second plate body 22 is provided with before and after a row to the second through erection bolt hole 22-1.
Preferably angle steel is adopted in material the present embodiment of support installing part 2.
The anchor ear 1 of the present embodiment and support installing part 2 all adopt batch production prefabricated, and during use, on-site consolidation connects, the size of anchor ear 1 and support installing part 2 according to the angle steel tower of practice of construction object need determine.
Connecting bolt 3 is for being connected anchor ear 1 with support installing part 2.
