Under a kind of Bailey bracket lower edge, hang i iron hood type device
Technical field
The utility model relates to hangs i iron hood type device under a kind of Bailey bracket lower edge.
Background technology
The current sharply period of expansion of highrise building that is in,, more and more higher building continues to bring out, and the application of backform system is also more and more extensive.In traditional backform system, Bailey bracket lower edge is that the mode that is bolted or welds is connected with crane girder i iron, and these connected mode versatilities are not strong, are not easy to dismounting at any time yet and move; For this reason, according to the feature of Bailey bracket self, invented under a kind of Bailey bracket lower edge and hung i iron hood type device, it is easy to operate, and highly versatile is convenient to dismounting at any time and is moved.
Utility model content
Technical problem to be solved in the utility model is to provide under a kind of Bailey bracket lower edge and hangs i iron hood type device, can significantly improve operating personnel's construction efficiency, and safe and reliable.
Technical problem to be solved in the utility model is achieved through the following technical solutions:
Under a kind of Bailey bracket lower edge, hang i iron hood type device, it is characterized in that: comprise platform connector i iron, U-shaped hood type fixture, junction plate and high-strength bolt, the bottom of described U-shaped hood type fixture is connected with described junction plate; Described U-shaped hood type fixture is embraced described platform connector i iron; Described high-strength bolt wears the two ends of described U-shaped hood type fixture, and connects with the top flange plate of described platform connector i iron; Described junction plate is provided with T-shaped groove, and the top flange plate of crane girder i iron inserts described T-shaped groove.
In such scheme, the width of described T-shaped groove is slightly larger than the width of described crane girder i iron top flange plate, and described T-shaped groove and described crane girder i iron top flange plate match.
In such scheme, described platform connector i iron and described crane girder i iron are perpendicular.
Compared with prior art, the beneficial effects of the utility model:
The utility model is that a kind of for hanging the fixture of i iron under Bailey bracket lower edge, it is simple in structure, easy to operate, highly versatile, and dismounting at any time, has improved the flexibility ratio of Bailey bracket combination, has widened the application surface of Bailey bracket.

In figure, 1-platform connector i iron, 2-U type hood type fixture, 3-crane girder i iron, 4-junction plate, 5-high-strength bolt.
Detailed description of the invention
In order to understand better the utility model, further illustrate content of the present utility model below in conjunction with accompanying drawing, but the utility model is not only confined to the following examples.
As Figure 1-3, hang i iron hood type device under a kind of Bailey bracket lower edge, comprise platform connector i iron 1, U-shaped hood type fixture 2, junction plate 4 and high-strength bolt 5, the bottom of described U-shaped hood type fixture 2 is connected with described junction plate 4; Described U-shaped hood type fixture 2 is embraced described platform connector i iron 1; Described high-strength bolt 5 wears the two ends of described U-shaped hood type fixture 2, and connects with the top flange plate of described platform connector i iron 1; Described junction plate 4 is provided with T-shaped groove, and the top flange plate of crane girder i iron 3 inserts described T-shaped groove.
The width of described T-shaped groove is slightly larger than the width of described crane girder i iron 3 top flange plates, and described crane girder i iron 3 top flange plates just can insert described T-shaped groove.
Described platform connector i iron 1 is perpendicular with described crane girder i iron 3.
In backform system installation process, need under Bailey bracket lower edge, hang i iron electrified monorail system is installed, U-shaped hood type fixture is entangled to platform connector i iron, then fix by high-strength bolt, again crane girder i iron top flange is inserted to the T-shaped groove on the lower end junction plate of U-shaped hood type fixture, Bailey bracket platform connector and crane girder i iron can be connected into an entirety.
