The bolt connection is one of the common connection modes between steel pipe structure rod pieces, the common direct welding connection mode is increasingly popular in the prior assembly type structure, a large amount of welding operation needs to be carried out on site, the requirement of the assembly type structure cannot be met, and a steel pipe structure rod piece connection mode which is convenient to construct and environment-friendly needs to be developed; the steel pipe is inconvenient to operate simultaneously on two sides, and a common bolt and nut connection fastening method cannot be used, so that a novel connection structure which can operate on one side, has superior performance and convenient and reliable construction and meets the requirements of building industrialization is urgently needed.
To this end, those skilled in the art have proposed an assembly type steel pipe connection structure using a one-side bolt connection to solve the problems set forth in the background above.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an adopt unilateral bolted connection's assembled steel pipe connection structure to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme:
the utility model provides an adopt unilateral bolted connection's assembled steel pipe connection structure, includes arc backing plate and connecting bolt, connecting bolt runs through main steel pipe, is connected with the nut behind the arc backing plate, and the branch pipe is fixed in on the arc backing plate.
As a further aspect of the present invention: the branch pipes include a left branch pipe and a right branch pipe.
As a further aspect of the present invention: the branch pipe is made of round steel, rectangular steel or I-shaped steel.
As a further aspect of the present invention: the arc-shaped base plate is matched with the main steel pipe.
As a further aspect of the present invention: the connecting bolts are in a plurality of groups and are symmetrically arranged on the main steel pipe.
As a further aspect of the present invention: the connecting bolt is perpendicular to the main steel pipe axis.
As a further aspect of the present invention: and a gasket is arranged between the screw cap and the main steel pipe.
Compared with the prior art, the beneficial effects of the utility model are that: the installation is more simple and convenient, and the fastening effect is reliable, need not to accomplish with the help of special instrument, satisfies the demand of assembled structure. In addition, only one side is needed for operation during use, so that bolt fastening operation can be completed, the problem that both sides of the steel pipe structure rod piece are not convenient to construct simultaneously is solved, and the steel pipe structure rod piece can be applied to actual construction and is good in using effect.

Detailed Description
The technical solution of the present patent will be described in further detail with reference to the following embodiments.
The first embodiment is as follows: referring to fig. 1-4, an assembled steel pipe connection structure using single-side bolt connection includes an arc-shaped backing plate 1 and a connection bolt 2, wherein bolt holes are reserved on the arc-shaped backing plate 1 and a main steel pipe 3, the connection bolt 2 is connected with a nut 4 after penetrating through the bolt holes on the main steel pipe 3 and the arc-shaped backing plate 1 during connection, a branch pipe 5 is fixed on the arc-shaped backing plate 1, and the branch pipe 5 includes a left branch pipe 51 and a right branch pipe 52 which are respectively welded to the arc-shaped backing plate 1.
The branch pipe 5 is round steel, rectangular steel or I-shaped steel.
The arc-shaped base plate 1 is matched with the main steel pipe 3.
The connecting bolts 2 are a plurality of groups and symmetrically arranged on the main steel pipe 3, and the connecting bolts 2 symmetrically arranged enable the connecting device to be stressed more uniformly.
The connecting bolt 2 is vertical to the axis of the main steel pipe 3.
Example two: this embodiment is a further improvement of the previous embodiment: be provided with gasket 6 between nut 4 and the main steel pipe 3, gasket 6 increases area of contact, reduces pressure, prevents to become flexible, protection connecting bolt 2.
The utility model discloses a kind of bolted connection structure between two steel pipes, reasonable in design only needs one side operation, the construction of being convenient for, and structural stability is strong, makes things convenient for the mill to prefabricate, and this structural system can realize standardized production, is applicable to the assembled structure, has improved construction speed, has reduced construction period, has reduced engineering cost.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
