Abstract
The utility model relates to a kind of external hanging type attachment device, including first connecting portion (1) and second connecting portion (2), the first connecting portion (1) and the second connecting portion (2) are arranged at obtuse angle；The first connecting portion (1) is attached in a plane of concrete structure (4) and is fixedly connected with the concrete pipe sheet splice bolt (3) in concrete structure (4)；The second connecting portion (2) is attached in another plane of concrete structure and fixes with one end of T connector bolt, and the other end of T connector bolt is fixedly connected with bracket.Bracket and concrete pipe sheet splice bolt are attached by the utility model external hanging type attachment device, so that bracket is easy to be fixed in tunnel, and the inner wall without destroying tunnel, easy for installation and stable structure.
Description
Technical field
The utility model relates to a kind of attachment devices, are especially that external hanging type attachment device is used in a kind of subway tunnel.
Background technique
Currently, the installation of most of subway tunnel cable, pipeline and equipment mainly uses anchor bolt mode, that is, use drilling side
Method mechanically or chemically anchor bolt will be implanted into concrete pipe sheet, using the cohesive force of mechanical swelling or chemical glue come fixed pipelines bracket.
Which is big to concrete pipe sheet structural damage, long in time limit, the big maintenance replacement cost height of construction environment pollution.In order to solve tradition
The defect of anchorage style, pre-buried anchor connector when can be prefabricated by concrete pipe sheet, for the fixed installation of equipment and pipeline,
Not damaged installation system starts to start to be applied in subway tunnel as a result,.
Meanwhile there are concrete inclined-plane and needing to connect with connecting bracket along loop tunnel, it is therefore desirable to which one is not
Tunnel wall can be damaged, and meet the external hanging type attachment device of tunnel structure.
Utility model content
The technical issues of the utility model devises a kind of external hanging type attachment device, solves be in existing tunnel construction,
Lacking a kind of pair of tunnel will not damage, while meet the external hanging type attachment device of tunnel structure.
In order to solve above-mentioned technical problem, the utility model uses following scheme:
A kind of external hanging type attachment device, it is characterised in that: including first connecting portion (1) and second connecting portion (2), described
One interconnecting piece (1) and the second connecting portion (2) are arranged at obtuse angle；The first connecting portion (1) is attached to concrete structure (4)
A plane on and be fixedly connected with the concrete pipe sheet splice bolt (3) in concrete structure (4)；The second connecting portion
(2) it is attached in another plane of concrete structure and is fixed with one end of T connector bolt, the other end and branch of T connector bolt
Frame is fixedly connected.
Further, the first connecting portion (1) is provided with connecting hole (11), and the concrete pipe sheet splice bolt (3) passes through
The connecting hole (11) is simultaneously fixed by nut with the first connecting portion (1).
Further, the second connecting portion (2) is equipped with square bolt hole (21), and limit is equipped in square bolt hole (21)
Piece, square bolt hole (21) and limit film cooperation prevent T connector bolt from rotating.
Further, there are two the square bolt hole (21) sets, respectively the first square bolt hole (21) and second rectangular
Bolt hole (22).
Further, the bracket is the bracket of the power supply unit, drainage equipment and the evacuation platform that use in tunnel.
The external hanging type attachment device has the advantages that
Bracket and concrete pipe sheet splice bolt are attached by the utility model external hanging type attachment device, so that bracket holds
It is easily fixed in tunnel, and the inner wall without destroying tunnel, easy for installation and stable structure.

Specific embodiment
Below with reference to Fig. 1 to Fig. 2, the utility model is described further:
A kind of external hanging type attachment device, including first connecting portion 1 and second connecting portion 2, first connecting portion 1 and the second connection
Portion 2 is arranged at obtuse angle；First connecting portion 1 be attached in a plane of concrete structure 4 and with the concrete in concrete structure 4
Concrete pipe sheet splice bolt 3 is fixedly connected；Second connecting portion 2 is attached in another plane of concrete structure and and T connector
One end of bolt is fixed, and the other end of T connector bolt is fixedly connected with bracket.
First connecting portion 1 is provided with connecting hole 11, and concrete concrete pipe sheet splice bolt 3 passes through connecting hole 11 and passes through spiral shell
Mother is fixed with first connecting portion 1.Second connecting portion 2 is equipped with square bolt hole 21, is equipped with limit in square bolt hole 21
Piece, square bolt hole 21 and limit film cooperation prevent T connector bolt from rotating.There are two square bolt hole 21 is set, respectively first
Square bolt hole 21 and the second rectangular bolt hole 22.
Bracket and concrete concrete pipe sheet splice bolt are attached by the utility model external hanging type attachment device, so that
Bracket is easy to be fixed in tunnel, and the inner wall without destroying tunnel, easy for installation and stable structure.
Illustrative description has been carried out to the utility model above in conjunction with attached drawing, it is clear that the realization of the utility model not by
The limitation of aforesaid way, if the method concept of the utility model and the various improvement of technical solution progress are used, or without
It improves and the conception and technical scheme of the utility model is directly applied into other occasions, in the protection scope of the utility model
It is interior.
