Steel pipe is transported, during installation, by deploying reinforcing plate successively around articulated section, connecting hole is alignd with fixing hole, and pass through bolt
Coordinate and fix, to fix reinforcing plate lower side and fixed plate, while steel pipe bottom end face is welded and fixed with fixed plate top surface, because
This makes construction very convenient, and it is very accurate to strengthen Board position.
In a kind of above-mentioned hollow steel pipe fixed structure, upper Positioning holes are provided with described gap slot, and work as reinforcing plate
When intrados is fitted on outer wall of steel pipe, described connecting hole is alignd with upper Positioning holes, and bolt, and spiral shell are bolted with connecting hole
Bolt end is screwed onto in upper Positioning holes.
Under normal circumstances, coordinated using bolt and connecting hole and upper Positioning holes and fixed, can be close to reinforcing plate intrados
On outer wall of steel pipe.
In a kind of above-mentioned hollow steel pipe fixed structure, described fixed plate is provided with some lower Positioning holes, and works as steel
When ttom of pipe end end face offsets with fixed plate top surface, described upper Positioning holes and lower Positioning holes alignment, and positioned by bolt
It is fixed.
Therefore overall positional accuracy can be improved.
In a kind of above-mentioned hollow steel pipe fixed structure, described reinforcing plate lower side and fixed plate top surface welding are solid
It is fixed.
Therefore the intensity of entirety can be improved.
In a kind of above-mentioned hollow steel pipe fixed structure, described fixed plate and reinforcing plate is steel plate.
Compared with prior art, the utility model has the following advantages that:
Under normal circumstances, reinforcing plate medial surface is fitted on outer wall of steel pipe, and now connecting plate is embedded in gap slot, with convenient
Steel pipe is transported, during installation, by deploying reinforcing plate successively around articulated section, connecting hole is alignd with fixing hole, and pass through bolt
Coordinate and fix, to fix reinforcing plate lower side and fixed plate, while steel pipe bottom end face is welded and fixed with fixed plate top surface, because
This makes construction very convenient, and it is very accurate to strengthen Board position.

Embodiment
The following is specific embodiment of the utility model and with reference to accompanying drawing, further is made to the technical solution of the utility model
Description, but the utility model is not limited to these embodiments.
As Figure 1-3, a kind of hollow steel pipe fixed structure of the utility model, including circular tube shaped hollow steel pipe 1 and tabular
Fixed plate 2, the top surface of fixed plate 2 is provided with some fixing holes 21, and the bottom end face of steel pipe 1 is vertical with the axis of steel pipe 1, and steel pipe 1 is the bottom of close to
The outer wall at end is provided with some articulated sections 11, axis and the diameter parallel of steel pipe 1 of articulated section 11, and some articulated sections 11 along steel pipe 1
Circumference is angularly distributed, in addition to some arc reinforcing plates 3, and the one side of reinforcing plate 3 is hinged on articulated section 11, the inner arc of reinforcing plate 3
Face is fitted on the outer wall of steel pipe 1 successively, and reinforcing plate 3 has the lower side concordant with the bottom end face of steel pipe 1, the intrados of reinforcing plate 3
Connecting plate 31 is provided with close to lower side position, connecting plate 31 is provided with connecting hole 32, and the outer wall bottom of steel pipe 1 is provided with some gap slots
12, and connecting plate 31 is embedded in gap slot 12 successively, and the bottom end face of steel pipe 1 can be made to be welded and fixed with the top surface of fixed plate 2, and lead to
