Problems solved by technology

Among them, bolt balls are often used in steel structure grids. As a sphere with multiple internal threaded holes, bolt balls can be used to connect multiple threaded rods to a node. Bolt balls can be mainly used in oil-free underground wells Oil production equipment, casing explosion expanders, oil pipe diameter gauges and other fields; most of the existing bolt balls have the problem of poor firmness and stability of the ball itself and its connection structure to threaded rods

Embodiment 1

[0020] A kind of bolt ball for steel structure connection, see figure 1 , the bolt ball for steel structure connection includes two hemispherical shells 1, the hemispherical shells 1 are provided with "ten" shaped reinforcing ribs 2, the inner ends of the reinforcing ribs 2 are provided with connecting screws 3, the ends of the hemispherical shells 1 Connecting screw holes are provided at the connecting screw rod 3 on the inner wall of the part, and four horizontal "L"-shaped arcuate grooves 4 are evenly distributed on the inner side wall of the hemispherical shell 1, and the circumferential direction of the arcuate surface groove 4 The groove surfaces are all arc-shaped surfaces, the radial groove surface of the arc-shaped groove 4 is a plane, and the circumferential side walls of the four rib plates of the reinforcing rib 2 are all set as arc-shaped surfaces matching the circumferential groove surfaces; see figure 2 , one of the hemispherical shells 1 is provided with a rai...

Embodiment 2

[0024] A kind of bolt ball for steel structure connection, similar to embodiment 1, the difference is, see Figure 4 , The cross-section of the corner post 8 is a right-angle sector. This can facilitate the joint connection between the corner post 8 and the "cross" shaped reinforcing rib 2.

[0025] preferred, see Figure 4 , the two sides of the corner post 8 are respectively connected with connecting plates 10, and the connecting plates 10 are respectively in contact with the side walls of the ribs. This can facilitate the connection of the corner post 8 with the rib plate through the connecting plate 10 . The connecting plate 10 can be connected to the corner post 8 through a bolt structure or a welding structure, and the connecting plate 10 and the corner post 8 can also be provided as an integrated structure.

[0026] Preferably, the connecting plate 10 and the rib plate are configured as metal parts connected by a welding structure.

[0027] preferred, see Figure 4 ,...

Embodiment 3

[0031] A kind of bolt ball for steel structure connection, similar to embodiment 1, the difference is, see Figure 5 , the circumferential groove surface of the arc groove 4 is an inclined arc surface. That is, if point a is taken on the circumferential groove surface of the arc groove 4, then the intersection point of the extension line of point a and the perpendicular to the central axis of the reinforcing rib 2 and the outer wall of the hemispherical shell 1 is point b, then the arc surface is made through point a The tangent line L1 of the circumferential groove surface of the groove 4 is the tangent line L2 of the outer wall of the hemispherical shell 1 through point b, and the angle between the tangent line L1 and the tangent line L2 is greater than 0° and less than 90°. In this way, the firm performance of the combined connection structure between the rib 2 and the hemispherical shell 1 can be further improved.

[0032] Preferably, the four circumferential side walls o...

Abstract

The invention discloses a bolt sphere for steel structure connection. A connecting screw rod extends into a connecting screw hole, and is in rotation connection with the inside of the connecting screwhole, then peripheral side walls of four rib plates of a reinforcing rib are respectively in contact with peripheral groove surfaces in a matched manner, and the radial side walls on the same side ofthe four rib plates of the reinforcing rib are all in contact with the radial groove surfaces; four outer connection screw holes uniformly distributed in the peripheral direction are formed in the side walls of hemispherical casings respectively; after a convex column of the reinforcing rib of one hemispherical casing extends to a column hole of the reinforcing rib of the other hemispherical casing, the two hemispherical casings are folded to form the bolt sphere; corner columns are arranged between adjacent rib plates of the crossed reinforcing ribs; inner connection screw holes are formed at the outer connection screw holes in the side walls of the corner columns, so as to improve the self firmness and stability of the sphere and the firmness and stability of a connection structure fora threaded rod piece.

Description

technical field [0001] The invention relates to the technical field of steel structures, in particular to a bolt ball for connecting steel structures. Background technique [0002] At present, steel structure, as a structure composed of steel materials, has become one of the main types of building structures. The steel structure is mainly composed of steel beams, steel columns, steel trusses, etc. The components or parts are usually connected by welds, bolts or rivets; steel structures are widely used in large factories, venues, super high-rises and other fields because of their light weight and easy construction. Among them, bolt balls are often used in steel structure grids. As a sphere with multiple internal threaded holes, bolt balls can be used to connect multiple threaded rods to a node. Bolt balls can be mainly used in oil-free underground wells In the fields of oil production equipment, casing explosion expanders, oil pipe diameter gauges, etc.; most of the existin...
