Abstract
The utility model belongs to the field of design and installation of steel structures, and discloses an integral cast-steel ball joint support which comprises an integral ball unit, a sliding base support, a box, an upper ball casing and the like. The integral cast-steel ball unit consists of a cast-steel ball joint and a rotary spherical core connected integrally, the sliding base support is mounted in the box, the upper ball casing is mounted above the box, a small ball of the steel ball unit is embedded in a groove of the base, and the upper ball casing above the box is fixedly connected with the box. The small ball of the ball joint support is used as the rotary spherical core integrally to be cast with the cast-steel ball joint which is connected with the same, so that a large integrally ball joint support is formed. Fillet welding between the ball joint support and the steel cast ball joint is avoided, and affection to structural safety due to poor quality of ultrathin steel cast is avoided.
Description
Technical field
The utility model belongs to structural steel design, installing area.
Background technology
Ball hinged support is mainly used in building large span network support node, be particularly useful for the airport, be station, Subway Facilities, stadiums, assembly hall exhibition room etc., in the network of steel work, ball hinged support (see figure 1) and connected upper and lower chord joint point spheroid are generally made respectively, employing is welded to connect rear formation support node (seeing Fig. 2, the model after the welding).Upper and lower chord joint point spheroid and bearing contact surface intractability are large, part engineering node spheroid intended diameter is larger, the general casting that adopts, weld seam is long between spheroid and bearing, ball hinged support ball and cast steel node ball fillet weld seam are owing to super thick cast steel welding quality is difficult to guarantee to affect structural safety.
Summary of the invention
The utility model purpose is to overcome above-mentioned not enough problem, and a kind of Contiuum type cast steel ball hinged support is provided, and is simple in structure, bears and transmit horizontal loading and the vertical load ability is strong, safe and reliable.
The technical scheme that the utility model adopts for achieving the above object is: a kind of Contiuum type cast steel ball hinged support, comprise conjoined cast steel ball portion and sliding bottom part, conjoined cast steel ball portion employing node cast steel ball and sphere turn the core integral-casting and are one, in the sliding bottom fixed installation casing, the casing top is equipped with spherical shell, the sphere of conjoined cast steel ball portion turns in the ball recess that core is inlaid in base, and the upper spherical shell of casing top is fixedly connected with casing.
Integrally casting has the rod member changeover portion on the described node cast steel ball.
The utility model takes the ball hinged support bead to turn core and the cast steel ball that links to each other (upper and lower chord joint point cast steel ball) monoblock cast as sphere, form huge Contiuum type ball hinged support, avoid ball hinged support ball and node cast steel ball fillet weld seam, avoided owing to super thick cast steel welding quality is difficult to guarantee to affect structural safety.Be in addition the welding quality of guarantor's node cast steel spheroid with the chord member weld seam that links to each other, adopt conjoined cast steel spherical zone rod member changeover portion, the Contiuum type ball hinged support turns the core monoblock cast by node cast steel ball (lower-chord panel point spheroid) and sphere, make node cast steel spheroid become the bearing inalienable part, in order to bear and to transmit horizontal loading and vertical load, safe and reliable.

The specific embodiment
Describe the utility model in detail below in conjunction with Fig. 3-5.
A kind of Contiuum type cast steel ball hinged support as shown in Figure 3, comprise conjoined cast steel ball portion (such as Fig. 4) and sliding bottom part (such as Fig. 5), conjoined cast steel ball portion employing node cast steel ball 1 turns core 2 integral-castings with sphere and is one, sliding bottom is that base 3 is fixedly mounted in the casing 4, the casing top is equipped with spherical shell 5, the sphere of conjoined cast steel ball portion turns in the ball recess that core 2 is inlaid in base, the upper spherical shell of casing top and casing be bolted to connection so that sphere to turn core spacing.Integrally casting has rod member changeover portion 7 on the described node cast steel ball.
During use, pipe trussed roof rod member is welded on the node cast steel ball by the rod member changeover portion on the node cast steel ball, node cast steel ball and sphere turn the core disjunctor, sphere turns core and puts into the semi-circular base groove, not only can rotate with base spaced winding cast steel ball and the spherical logical line of the centre of sphere that turn core, and can and the base vertical line between any direction form angle.
Claims (2)
1. Contiuum type cast steel ball hinged support, comprise conjoined cast steel ball portion and sliding bottom part, it is characterized in that: the conjoined cast steel ball portion adopts node cast steel ball and sphere to turn the core integral-casting and is integral, in the sliding bottom fixed installation casing, the casing top is equipped with spherical shell, the sphere of conjoined cast steel ball portion turns core and is inlaid in the base ball recess, and the upper spherical shell of casing top is fixedly connected with casing.
2. a kind of Contiuum type cast steel ball hinged support according to claim 1, it is characterized in that: integrally casting has the rod member changeover portion on the described node cast steel ball.
