Description

TECHNICAL FIELD

[0001] The present application relates to the field of metal net rack construction, in particular to a new type of ball valve bolt ball connecting node. BACKGROUND

[0002] The space property of the connecting structure of the net shell structure can fully exert the superiority of the three-dimensional shortcut force transmission of space. The node plays a key role in the three-dimensional force of the net shell structure. At present, there are many node forms applied in the space net shell and net rack structure, which are mainly divided according to the structure: welded hollow ball node, bolt ball node, related node and welded steel plate node. The welded hollow ball node and the bolt ball node are the most commonly used node forms in the single-layer net shell structure.

[0003] Welding has high requirements on the overall compression capacity and the anti-seismic capacity. The residual capacity of welding can cause brittle failure of the overall structure during the welding process, easily deforming the thin-walled rod, and the welding quality is not easy to guarantee, which is time-consuming and laborious. At present, the high-strength bolt connection of the net rack node often exists in the situation of not being tightened, or the gap and looseness at the connection, which makes the bearing capacity of the net rack structure not meet the design requirements, affects the installation quality, and leads to the increase of the structure deformation.

[0004] The above situations are common in the field construction process, and the connection quality of the space net rack rod cannot be completely guaranteed. Therefore, a detachable node connection mode which is simple to operate, convenient to install, time-saving and labor-saving and can improve the work efficiency is needed to solve the problems of inconvenient connection and unguaranteed installation quality in the current traditional space net rack rod connection. SUMMARY

[0005] In view of the problems of large labor intensity, low construction efficiency and unguaranteed construction quality in the current net rack node connection construction process, the present application provides a new type of ball valve bolt ball connecting node. In the construction process, the operation of rotating the net rack rod is not needed, only the side of the rod with the clamping groove is engaged with the bolt ball valve groove of the designed position node, after the rod of the designed position node is engaged, the connection of the ball valve and the bolt rod is realized through the high-strength bolt, and the complete ball is formed by connecting the ball valves through the high-strength bolt.

[0006] The technical solution adopted by the present invention to solve the technical problem is to provide a novel spherical valve type bolted spherical connection node, which includes: a filling spherical valve, a connecting spherical valve, and a connecting rod. The connecting spherical valve is composed of two small spherical valves and a connecting plate. The small spherical valve includes a spherical seat, on the arc surface of which bolt holes are provided. On one side of the spherical seat, a connecting wing is provided, and on the other side, a fixing groove is provided. One end of the connecting rod is snapped into the fixing groove, and the two small spherical valves are assembled and fixed by high-strength bolts passing through the connecting plate and the bolt holes. Multiple filling spherical valves and multiple connecting spherical valves are assembled to form a sphere and are connected and fixed.

[0007] Preferably, the filling spherical valve includes a side plate, a web plate, and a rib plate. The side plate is provided with bolt holes, and the web plate and the rib plate are perpendicularly arranged to improve the structural strength. The connecting wing is provided with bolt holes, and the side plate and the connecting wing are fixed by high-strength bolts passing through the bolt holes.

[0008] Preferably, the connecting rod includes a bolt rod, a sleeve, an opening and closing sealing plate, and a web member. The bolt rod includes a bolt rod shaft. On both sides symmetrically at one end of the bolt rod shaft, fixing bosses are provided, and at the other end, fixing threads are provided. The fixing bosses are in a "Feng" type structure, and the fixing groove is in a "Feng" type structure matching the fixing bosses to ensure that the fixing bosses are firmly snapped into the fixing groove. The connecting end of the web member is inserted into the opening and closing sealing plate, and the tail of the sleeve contacts the opening and closing sealing plate. A double-headed high-strength bolt is used for connection, and the sleeve is tightened by screwing a nut into the fixing threads.

[0009] Preferably, the filling spherical valve and the connecting spherical valve are connected by high-strength bolts.

[0010] Preferably, by assembling the filling spherical valves and the connecting spherical valves at various angles, applications in various usage scenarios are achieved.

DETAILED DESCRIPTION

[0023] The preferred embodiments of the present application will be described in more detail below. Although the preferred embodiments of the present application are described below, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present application is more thorough and complete, and the scope of the present application is fully conveyed to those skilled in the art.

[0024] As shown in Figures 1-2 , Figures 4-6 The present embodiment provides a new ball valve type bolt ball connection node, which comprises a filled ball valve 1, a connected ball valve 2, and a connecting rod 3. The connected ball valve 2 is composed of two small ball valves 210 and a connecting plate 6. The small ball valve 210 includes a ball seat 212, which is provided with a bolt hole 5 on the curved surface. The ball seat 212 is provided with a connecting wing 211 on one side and a fixing groove 213 on the other side. The connecting rod 3 is inserted into the fixing groove 213. The two small ball valves 210 are spliced and connected and fixed by high-strength bolts passing through the connecting plate 6 and the bolt hole 5. Multiple filled ball valves 1 and multiple connected ball valves 2 are spliced to form a spherical shape and are connected and fixed. As shown in Figure 3As shown, the filled spherical valve 1 includes side plates 101, web plates 102, and rib plates 103. The side plates 101 are provided with bolt holes 5. The web plates 102 and the rib plates 103 are arranged perpendicular to each other to improve the structural strength. The connecting wing 211 is provided with bolt holes 5. The side plates 101 and the connecting wing 211 are fixed by high-strength bolts passing through the bolt holes 5.

[0025] As Figures 7-8 shown, the connecting rod 3 includes a bolt rod 310, a sleeve 320, an opening and closing sealing plate 330, and a web member 340. The bolt rod 310 includes a bolt rod shaft 311. On both sides symmetrically at one end of the bolt rod shaft 311, there are fixed bosses 312, and at the other end, there is a fixed thread 313. The fixed boss 312 has a "Feng" - shaped structure, and the fixed groove 213 has a "Feng" - shaped structure matching the fixed boss 312. The "Feng" - shaped structure can ensure that the horizontal card slot transmits the axial force of the rod, and the vertical card slot is used to prevent the bolt rod from twisting, ensuring that the fixed boss 312 is firmly stuck into the fixed groove 213. The connecting end of the web member 340 is inserted into the opening and closing sealing plate 330, and the tail of the sleeve 320 contacts the opening and closing sealing plate 330. A double - headed high - strength bolt is used for connection, and the sleeve 320 is tightened by screwing a nut into the fixed thread 313.
