Description
Technical Field
The utility model relates to a steel construction technical field, in particular to high strength bolt is used to bolt ball node.
Background
The space lattice structure is widely applied in the world in recent years, particularly in China, the common node form of the space lattice structure is a welding ball node and a bolt ball node, for the bolt ball node space lattice structure, a rod piece is connected with the bolt ball node through a high-strength bolt, a shallow groove and a deep groove are carved on the surface of the bolt along the axial direction, a screw hole is formed in a sleeve, when in construction and installation, the sleeve is sleeved into the bolt, a pin is firstly screwed into the screw hole of the sleeve until the top end of the sleeve is pushed to the shallow groove, the sleeve can be rotated to drive the bolt to rotate together through the pin, so that the bolt can be screwed into a corresponding screw hole of a bolt ball until the surfaces of the sleeve and the bolt ball are tightly pushed, at the moment, the pin is required to reach the bolt deep groove, then the pin is rotated again until the top end of the bolt is pushed into the deep groove, in the installation process, the synchronous rotation, the pin is easy to be twisted off, causes the unable tightening of high strength bolt, promptly "false twisting" phenomenon, and this is one of the key problem that generally exists in bolt ball node grid structure installation at present, moreover, adds man-hour to bolt and rotatory sleeve, needs additionally to carry out drilling process, leads to the manufacturing procedure many, and process time is long, the cost-push.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a main aim at provides a high strength bolt is used to bolt ball node can effectively solve the problem that the pin is easily twisted off among the background art, and manufacturing procedure is many.
In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a high strength bolt for bolt ball node, includes the bolt ball, a plurality of screws have been seted up on the bolt ball, every the screw rotates and is connected with the bolt, the bolt includes bolt head, dead lever and threaded rod from the right side to a left side in proper order, the bolt head is T type structure, the bolt passes through threaded rod and screw threaded connection, the dead lever is non-cylindrical structure, the member has been cup jointed to the bolt head, the outside of dead lever cup jointed rather than outer lane assorted axle sleeve, just the outer lane of axle sleeve is hexagonal prism structure.
Preferably, the outer ring of the fixing rod is of a quadrangular prism structure, a hexagonal prism structure or an octagonal prism structure.
Preferably, the diameter of the fixing rod is smaller than that of the bolt head, and the joint of the fixing rod and the bolt head is connected through an arc surface.
Preferably, the inner ring of the shaft sleeve is provided with an inner ring matched with the cambered surface.
Preferably, the length of the shaft sleeve is greater than that of the fixing rod.
Preferably, the outer diameter of the sleeve is smaller than that of the rod.
Compared with the prior art, the utility model discloses the beneficial effect who produces is:
1. this high strength bolt for bolt ball node, when installing the use, cup joint the member at the bolt head, cup joint the shaft sleeve, the dead lever outer lane phase-match of shaft sleeve inner chamber and screw rod this moment, both are locked each other, just can carry out threaded connection with bolt and bolt ball through rotatory shaft sleeve, can not use the pin, avoided "false twisting" phenomenon because of the fracture production of pin, guarantee the security of structure, only need process the inner circle of shaft sleeve, and the process of the pinhole of having saved processing, processing is simple and convenient.
2. This high strength bolt for bolt ball node is less than the diameter of bolt head through the diameter that sets up the fixed bar, plays spacing effect to the axle sleeve, and avoids through setting up such stop device of pin, and the inner circle that directly passes through the axle sleeve after the processing locks mutually with the bolt, and the processing of driling when having avoided setting up the pin saves manufacturing procedure, practices thrift process time.
3. This high strength bolt for bolt ball node, the junction of dead lever and bolt head is connected through the cambered surface for both connect more tightly, avoid the cracked condition of junction.

Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.
As shown in fig. 1-5, a high strength bolt for bolt ball node, includes bolt ball 1, a plurality of screws 2 have been seted up on bolt ball 1, every screw 2 rotates and is connected with bolt 5, bolt 5 includes bolt head 51, dead lever 53 and threaded rod 54 from the right side to a left side in proper order, bolt head 51 is T type structure, makes things convenient for the member to fix, bolt 5 passes through threaded rod 54 and 2 threaded connection of screw, dead lever 53 is non-cylindrical structure, makes axle sleeve and dead lever lock mutually, avoids using the pin, bolt head 51 has cup jointed member 4, the outside of dead lever 53 has cup jointed rather than outer lane assorted axle sleeve 3, and the outer lane of axle sleeve 3 is hexagonal prism structure, makes things convenient for the fastening operation.
In this embodiment, the outer ring of the fixing rod 53 is a quadrangular prism, a hexagonal prism or an octagonal prism structure, so that the shaft sleeve and the fixing rod can be better locked.
