Abstract
The utility model discloses an anti-sliding type steel structure connecting device. The anti-sliding type steel structure connecting device comprises a pair of square hollow connecting square bars, a detachable connecting core tube is arranged between the connecting square bars, the edge of one side of each connecting square bar is provided with a perforative connecting through hole, and the connecting core tube comprises a cylindrical core tube body. A pair of axially-arranged adjusting long grooves and a pair of locking circular groove arrays composed of locking circular grooves are symmetrically arranged on the side wall of the core tube body, and a pair of locking screws penetrates through the connecting through holes and the connecting core tube respectively. Due to the fact that the steel structure connecting device is provided with the locking circular grooves, a user can select the grooves according to actual needs, the steel structure connection flexibility is greatly improved, connection is firm, and the practicability is high.
Description
Technical field
The utility model relates to a kind of steel work, or rather, is a kind of anti-slip type steel structure connecting device.
Background technology
In structural steelwork adopt the members such as girder steel that shaped steel, tubing etc. make, steel column, steel truss more, and utilize screw to connect.In the time carrying out square steel connection, conventionally utilize external cover frame to be fixed, connection dynamics is limited, and in addition, the orientation distance of this cover frame is single, cannot regulate.
Utility model content
The utility model is mainly to solve the existing technical problem of prior art, thereby a kind of anti-slip type steel structure connecting device is provided.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of anti-slip type steel structure connecting device, the connection square steel of the hollow that described anti-slip type steel structure connecting device comprises a square shaped, between described connection square steel, be provided with a dismountable connection-core cylinder, one lateral edges of described connection square steel is provided with a connecting through hole running through, described connection-core cylinder comprises a core cylinder main body cylindraceous, on the sidewall of described core cylinder main body, be provided with symmetrically adjusting elongated slot and a pair of locking annular groove array being formed by locking annular groove of a pair of axial setting, connecting through hole described in a pair of lock bolt runs through respectively and described connection-core cylinder.
As the utility model preferred embodiment, the setting party of described adjusting elongated slot is to mutually vertical with described locking annular groove.
Anti-slip type steel structure connecting device of the present utility model utilizes adjusting elongated slot and the locking annular groove on connection-core cylinder, user can be run through lock bolt the connecting through hole connecting on square steel, and make lock bolt run through adjusting elongated slot, then be rotationally connected square steel, make lock bolt snap in locking annular groove.This steel work is owing to having multiple locking annular grooves, and user can select according to actual needs, has greatly expanded the flexibility of steel structure connection, is connected firmly, practical.

Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.
As shown in Figures 1 to 4, the connection square steel 2 of the hollow that anti-slip type steel structure connecting device 1 of the present utility model comprises a square shaped, between this connection square steel 2, be provided with a dismountable connection-core cylinder 3, one lateral edges of this connection square steel 2 is provided with a connecting through hole running through 21, this connection-core cylinder 3 comprises a core cylinder main body 31 cylindraceous, on the sidewall of this core cylinder main body 31, be provided with symmetrically adjusting elongated slot 32 and a pair of locking annular groove array being made up of locking annular groove 33 of a pair of axial setting, a pair of lock bolt 4 runs through respectively this connecting through hole 21 and this connection-core cylinder 3.
The setting party of this adjusting elongated slot 32 is to mutually vertical with this locking annular groove 33.
The anti-slip type steel structure connecting device of this utility model utilizes adjusting elongated slot and the locking annular groove on connection-core cylinder, user can be run through lock bolt the connecting through hole connecting on square steel, and make lock bolt run through adjusting elongated slot, then be rotationally connected square steel, make lock bolt snap in locking annular groove.This steel work is owing to having multiple locking annular grooves, and user can select according to actual needs, has greatly expanded the flexibility of steel structure connection, is connected firmly, practical.
Be not limited to this, any variation of expecting without creative work or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
