Abstract
The utility model relates to an ultrastrength bolt connecting device for grid structure, principally comprising a pole pipe, a bolt ball, a conic head or a closing plate, a high strength bolt and a liner. The device is characterized in that the identical screw clasps are arranged in the bolt ball, on the high strength bolt, in the circular hole of the conic head or the closing plate, and in the liner. The high strength bolt is screwed in from the hole of the conic head or the closing plate, and the liner outside of the conic head or the closing plate is screwed on the high strength bolt. The conic head or the closing plate is welded with the pole pipe to form a fixing end, and meanwhile the part of the high strength bolt stretching out of the liner is screwed into the bolt ball. The utility model has the advantages of convenient processing, manufacturing and usage, improving the work efficiency.
Description
The utility model relates to a kind of building structure, is meant a kind of net frame high-strength bolt linkage especially.
At present, the production of space truss structure, though can realize the production of batch production (Automation of Welding), assembling aided process at the scene is various, the assembling Quality Control degree-of-difficulty factor is higher.By Chinese utility model patent: 92234561.9 disclosed " a kind of no pin link techniques ", though improved many than original pin connection, but because the method for using welding is fixed high-strength bolt and conehead or shrouding, and the high temperature of welding certainly will make the intensity of conehead or shrouding and high-strength bolt junction descend, and has stayed the hidden danger of engineering construction; Simultaneously in sleeve, high-strength bolt Surface Machining groove and breach, also have certain degree of difficulty and corresponding machining period.
The purpose of this utility model is to overcome the deficiency in the background technology and a kind of net frame high-strength bolt linkage is provided.
The utility model purpose is achieved in that it is mainly by rod tube, bolt sphere, conehead or shrouding, high-strength bolt, sleeve are formed, and it is characterized in that: in the bolt sphere, on the high-strength bolt, in the circular hole of conehead or shrouding, all attacked identical spiral shell in the sleeve and buckle; High-strength bolt is screwed into and screws out in the hole of conehead or shrouding, sleeve is screwed on the high-strength bolt outside conehead or shrouding, conehead or shrouding and rod tube weld together, and form a fixed end, and the part that high-strength bolt is stretched out outside sleeve is screwed in the bolt sphere.
Wherein, described fixed end links for no pin; It is a kind ofly can directly be screwed into steel ball, and by high-strength bolt conehead or shrouding and sleeve is connected to holistic stressed member.
Advantage of the present utility model is: process, manufacture, use all easily, improved operating efficiency.
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the schematic diagram of high-strength bolt in the utility model.
Fig. 3 is the vertical view of the utility model middle sleeve.
Fig. 4 is the front view of the utility model middle sleeve.
Fig. 5 is the fragmentary cross-sectional view that conehead is connected with high-strength bolt in the utility model.
Fig. 6 is the fragmentary cross-sectional view that shrouding is connected with high-strength bolt in the utility model.
Below in conjunction with Figure of description and embodiment, the utility model is further described:
As Fig. 1-shown in Figure 6, the utility model mainly is made up of rod tube 8, bolt sphere 4, conehead or shrouding 1, high-strength bolt 2, sleeve 3.Wherein, in bolt sphere 4, on the high-strength bolt 2, in the circular hole of conehead or shrouding 1, all attack identical spiral shell in the sleeve 3 and buckle 9,7,5,6: high-strength bolt 2 is screwed into and screws out in the hole of conehead or shrouding 1; Sleeve 3 is screwed on the high-strength bolt 2 outside conehead or shrouding 1; Conehead or shrouding 1 weld together with rod tube 8; Form a fixed end, fixed end links for no pin, and fixed end is by high-strength bolt conehead (shrouding) and sleeve to be connected to a whole stressed member, and the part that high-strength bolt 2 stretches out outside sleeve 3 is screwed in the bolt sphere 4; The platform of conehead or shrouding 1 and rod tube 8 joints are an inclined-plane 10 that shrinks, and the stub end of conehead 1 is a hollow cavity 11, and its bore is identical with rod tube 8 diameters.
