Abstract
An auxiliary device for butt joint of large steel tubes comprises multiple lug plates arranged on the outer walls of the ends of the two steel tubes in butt joint. Clamping plates are arranged in pairs on the two sides of two lug plates and located on the outer walls of the two steel tubes in butt joint respectively, and the positions of the two lug plates are in a straight line correspondingly. The lug plates and the clamping plates are connected through bolts and nuts. Each lug plate is provided with multiple first fixing holes. Each clamping plate is provided with multiple second fixing holes. The bolts penetrate through the first fixing holes and the second fixing holes and are assembled with the nuts. The auxiliary device for butt joint of the large steel tubes can guarantee accurate alignment and welding quality of the large steel tubes, and is simple in arrangement structure, easy to manufacture and convenient to operate.
Description
Technical field
A kind of large-scale steel pipe butt joint auxiliary device of the utility model, docks for large-scale steel pipe.
Background technology
In high-story architecture construction, often adopt large-scale steel pipe grid posts structure, the diameter of steel pipe reaches 2 meters above and need to dock in the air at height.The flange plate bolt connected mode that steel pipe docking adopts conventionally.Which exists that overhead connection difficulty is large, construction cost is large, affect the shortcomings such as building is attractive in appearance and do not adopted.And exist at the aerial directly welding manner of height, contraposition is inaccurate, welding quality is difficult to the problem guaranteeing, the steel pipe being particularly in tilted layout docking problem is particularly outstanding.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of large-scale steel pipe butt joint auxiliary device, can guarantee large-scale steel pipe contraposition accurately and welding quality.And arrange simple in structure, be easy to make, easy to operate.
The technical scheme that the utility model is taked is: a kind of large-scale steel pipe butt joint auxiliary device, comprise a plurality of otic placodes that are arranged in two docking steel tube end part outer walls, lay respectively at the both sides that two docking outer wall of steel pipe, position correspondences are two otic placodes of straight line and be laid with in pairs clamping plate, described otic placode is connected by bolt, nut with described clamping plate.Each otic placode is provided with a plurality of the first fixing holes, and each clamping plate is provided with a plurality of the second fixing holes, and bolt is through the first fixing hole, the second fixing hole and nut assembling.
It is axle center that described a plurality of otic placode be take docking steel pipe central shaft, is equidistantly vertically distributed in docking steel tube end part outer wall.
Described the first fixing hole, the second fixing hole are circular hole, and the first fixing hole is concentric with the second fixing hole and internal diameter is identical.
Described the first fixing hole is two rows, is evenly distributed on otic placode.Described the second fixing hole is two rows, is evenly distributed on clamping plate.
Described otic placode is apart from docking steel tube end part certain distance.
A kind of large-scale steel pipe butt joint auxiliary device of the utility model, by otic placode, clamping plate and bolt, the nut laid on docking steel pipe.Can docking steel pipe contraposition accurately, then the welding of docking steel pipe can guarantee welding quality.Be specially adapted to the overhead connection of large-scale steel pipe, especially can solve the large problem of steel pipe docking difficulty being in tilted layout.

The specific embodiment
As shown in Fig. 1 ~ Fig. 5, a kind of large-scale steel pipe butt joint auxiliary device, comprise a plurality of otic placodes 1 that are arranged in two docking steel pipe 5 end outer walls, lay respectively at the both sides that two docking steel pipe 5 outer walls, position correspondences are two otic placodes 1 of straight line and be laid with in pairs clamping plate 2, described otic placode 1 is connected by bolt 3, nut 4 with described clamping plate 2.Each otic placode 1 is provided with a plurality of the first fixing holes 6, and each clamping plate 2 is provided with a plurality of the second fixing holes 7, and bolt 3 is through the first fixing hole 6, the second fixing hole 7 and nut 4 assemblings.
It is axle center that described a plurality of otic placode 1 be take docking steel pipe 5 central shafts, is equidistantly vertically distributed in docking steel pipe 5 end outer walls.The utility model is each root docking steel pipe 5 end preferably, arranges that 1, four otic placode 1 of four otic placodes is evenly distributed on four quadrantal points places on the circumferential section that docks steel pipe 5, as shown in Figure 2.
The utility model preferably the first fixing hole 6, the second fixing hole 7 is circular hole, and the first fixing hole 6 is concentric with the second fixing hole 7 and internal diameter is identical.The utility model preferably the first fixing hole 6 is two rows, is evenly distributed on otic placode 1; The second fixing hole 7 is two rows, is evenly distributed on clamping plate 2, as shown in Figure 3, Figure 4.While guaranteeing steel pipe docking, location is more accurate, increases bonding strength.
Described otic placode 1 is apart from docking steel pipe 5 end certain distances, and while preventing from docking, two otic placode 1 phase mutual interference, affect docking, and described certain distance is: the neutral gear that leaves this place's steel-pipe welding.
Implementation step:
In processing space, otic placode 1 is welded on to the outer wall of docking steel pipe 5, with crane, steel pipe 5 to be docked is winched to fixing steel pipe top, one by one clamping plate 2 are laid in to otic placode 1 both sides, in the first fixing hole 6, the second fixing hole 7, penetrate bolt 3 fastening nut 4, so far complete the location of docking steel pipe 5 and fix, then docking the welding of steel pipe seam 8.Weld rear dismounting clamping plate 2, cut off otic placode 1.
