The utility model content
The purpose of this utility model is to propose a kind of tree net formed steel construction connected node system, and it is reasonable in design, and simple in structure firmly accuracy is good, is convenient to construction, and is with low cost, thereby overcome deficiency of the prior art.
For achieving the above object, the utility model has adopted following technical scheme:
A kind of tree net formed steel construction connected node system, comprise that complex root connects rod member, it is characterized in that, described connected node system also comprises ring-stiffened rib, shrouding, backing plate and bolt, described shrouding is fixedly installed on an end port part that connects rod member, behind described screw bolt passes backing plate, ring-stiffened rib and the shrouding with to be connected rod member one end fixedly connected.
Say further, also be provided with limiting plate on the described shrouding.
Described ring-stiffened rib comprises a circle tube member, and described backing plate is sticked on the inwall of circle tube member.
Described backing plate profile is curved surface.
Seal with steel plate at described circle tube member two ends, and on the described steel plate LED lamp is installed.
Compared with prior art, advantage of the present utility model is:
(1) quite complicated steel work is connected, become simple, be convenient to process and install by design cleverly, and manufacturing and construction precision height;
(2) can guarantee to connect the angle of rod member by the gradient of processing shrouding end face, make the establishment of steel work more accurate;
(3) all connection rod member all is fixed on mainly on the ring-stiffened rib that is made of steel cylinder by high-strength bolt, connects very firmly, safety;
(4) backing plate of curved surface is set in the ring-stiffened rib, can further increases the frictional force of backing plate and steel cylinder inwall, thereby increase bonding strength.
In general, the utility model is simple in structure, is easy to processing, is convenient to construction, system's machining accuracy height, and appearance looks elegant connects reliable, safety, is suitable for setting up as complicated steel work such as net type, umbellate form, branch type.

The specific embodiment
Below in conjunction with an accompanying drawing and a preferred embodiment the technical solution of the utility model is elaborated.
See also Fig. 2-3, present embodiment comprises that steel connects rod member 1, high-strength bolt 2, shrouding 3, backing plate 4, ring-stiffened rib 5 and LED lamp 6; Wherein, ring-stiffened rib 5 is a circular steel cylinder, shrouding 3 is fixedly installed on rod member 1 and the end that the steel cylinder outer wall is connected, and shrouding 3 can form required profile with the predetermined connection angle of steel cylinder by machining according to rod member 1, high-strength bolt 2 passes the steel cylinder barrel fixedlys connected with rod member 1 with shrouding, and can be provided with limiting plate restriction high-strength bolt play (not shown) on the shrouding, more tight for allowing bolt 2 combine with the steel cylinder barrel, can set up a backing plate 4 in steel cylinder, backing plate 4 can be processed to the curved surface that cooperates with the steel cylinder inwall.The two ends of steel cylinder can be sealed with a tube internal diameter steel plate of a size by diameter, on steel plate the LED lamp can be installed, and LED lamp cabling can be arranged in the inner chamber of rod member.
Above embodiment is only for the usefulness that the utility model is described, but not to restriction of the present utility model, person skilled in the relevant technique is under the situation that does not break away from spirit and scope of the present utility model, do various conversion or modification, all belonged to category of the present utility model.
