Abstract
The utility model discloses a late-model steel net frame bolt ball joint structure, mainly comprising a connecting body, a bolt, a sleeve and the fixing element of the bolt and the sleeve, wherein, the fixing element is composed of a keyway on the bolt and a flat key inserted in the sleeve. A spring device is also arranged in the connecting body. The utility model has the advantages of reasonable structure, rapid installation and convenient loading and unloading, and the mutual turning resistance ability between the bolt and the sleeve is increased by more than three times.
Description
The utility model belongs to zero, the parts of grid structure with bolt-sphere joints, and specifically, it relates to a kind of structure of coupling head of steel mesh frame bolted spherical node
The steel mesh frame is a kind of building framework, and a kind of steel mesh frame of bolted spherical node is wherein arranged, and its coupling head is mainly by forming with affixed connected body, the bolt that is threaded with bolt sphere and the sleeve of connecting rod.Sleeve and bolt are affixed by fixture.Fixture is a jackscrew, and sleeve and bolt is affixed.The main deficiency of this class coupling head is: the top wire hole on the sleeve is inclined to one side slightly, and jackscrew just be can't hold out against bolt, thereby produces the slip or the jackscrew phenomenon that fractures; Owing to require top wire hole to align when installing, therefore cause construction, inconvenience is installed; , jackscrew fractures dismounting, replacing trouble in case taking place.
The purpose of this utility model is exactly in order to overcome the deficiencies in the prior art, propose a kind of rational in infrastructure, the reliability height; The steel mesh frame bolted spherical node coupling head of installation, replacing, convenient disassembly.
The purpose of this utility model be achieved in that the utility model by desire the connected body 2 affixed with the connecting rod 1 of steel mesh frame, bolt 4 and the sleeve 5 that desire is threaded with bolt sphere (node) 3 formed.Fixture between sleeve and the bolt is made of the internal keyway on the outside keyway on the bolt 6, flat key 7 and the sleeve 8, and flat key is set in the internal keyway on the sleeve.
Owing to adopted technique scheme, major advantage of the present utility model is: rational in infrastructure, and make the anti-mutual turning power (anti-shear ability) between bolt and sleeve increase more than three times; Convenient disassembly is installed rapidly.
The drawing of the utility model accompanying drawing is described as follows:
Fig. 1 is a structural representation of the present utility model.
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing: in an embodiment, connected body is a concentric reducer circular cone cavity, and the spring 9 that presses bolt head wherein is housed.Be stamped spring base 10 on the spring.A hole is arranged with back-up ring 11 on spring base, spring base is limited in the chamber of connected body.Because the above-mentioned spring assembly in the connected body makes in installation process, bolt can not be withdrawn into and connect in the body cavity; And after bolt and bolted node sphere were fastening, spring played anti-loosening effect again.
Claims (2)
1, a kind of steel mesh frame bolted spherical node coupling head, form by connected body, bolt and sleeve, sleeve and bolt are affixed by fixture, and it is characterized in that: fixture is made of the internal keyway on the outside keyway on the bolt, flat key and the sleeve, and flat key is set in the internal keyway of sleeve.
2, according to the coupling head of the described steel mesh frame of claim 1 bolted spherical node, it is characterized in that: connected body is a concentric reducer circular cone cavity, and the spring that presses bolt head wherein is housed, and is stamped spring base on the spring, one hole ring washer is arranged on spring base, spring base is limited in the chamber of connected body.
