Abstract
Welding welded hollow spherical joint is widely used in large -span spatial structure as one of spatial structure node form. The main destruction form of welded ball is cut destruction, and the reason is great when the sphere diameter, leads to the spheroid relative when thin, its connect steel pipe draw press spheroidal process in the middle of, handing -over department can take place to flake or press the sunken condition, or even the member directly breaks away from the spheroid. Through evenly setting up the cyclic annular stiffening rib that four the same width are the fourth welded ball diameter, stiffening rib and member and sphere welding in original welding clean shot ball wall outside to increase welding welded hollow spherical joint's bearing capacity.
Description
Technical field
This utility model belongs to large span spatial structure field, particularly relates to a kind of welded hollow spherical joints design, and large span spatial structure is widely used in the buildings such as various large-scale stadium, hangar, Convention and Exhibition Center, all types of industries Factory Building.
Background technology
At present, owing to state of China adult is many, along with the continuous enhancing of national power, build more bigger physical culture, lie fallow, put on display, air harbor, long-span space or the super-span space buildings thing such as hangar, to meet the demand of China's economic growth and social progress.Welded hollow spherical joints is the important component part of long-span space building, needs to bear pulling force and the pressure that rod member transmits.
Welded hollow spherical joints, as one of space structure joint form, is widely used in large-span space structure.Discrete rod member becomes a structure by set of node, so in spatial mesh structure system, the tectonic sieving of node and intensity are all highly important.Welded hollow spherical joints applicating history is the longest, has simple structure, easy to connect, does not produce the advantages such as node bias, thus is widely applied.Rod member axle power effect is mainly born in solder sphere junction, and solder sphere itself is also axially symmetric structure simultaneously, and rod member all acts on the centre of sphere, so stress does not has bias.The main failure mode of solder sphere is mainly sheared destruction, and reason is when sphere diameter is relatively big, and when causing spheroid relatively thin, its joint steel pipe is in the middle of the process of tension and compression spheroid, and the situation that junction can flake or collapse, even rod member directly depart from spheroid.For improving the bearing capacity of weldering hollow ball node, a kind of bearing need to be researched and developed and draw more greatly load and the Novel welding hollow ball node of pressure load.
Summary of the invention
In order to overcome the deficiency of existing welded hollow spherical joints, this utility model provides a kind of Novel welding hollow ball node, increases the bearing capacity of this welded hollow spherical joints.
This utility model solves its technical problem and be the technical scheme is that by being uniformly arranged the ring-type ribbed stiffener that four identical width are 1/4th solder sphere diameters outside original welding hollowing ball ball wall, ribbed stiffener welds with rod member and sphere, thus increases the bearing capacity of welded hollow spherical joints.
Effective benefit of the present utility model is to increase Load-carrying capacity of welded hollow spherical, simple in construction.
Accompanying drawing explanation
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is this utility model front view.
Fig. 2 is this utility model top view.
Detailed description of the invention
In the construction stage, in Fig. 1, first rod member (3) is welded with former welding hollowing ball (1), after welding terminates, more ring-type ribbed stiffener (2) two twenty percent 90 degree that 4 identical is welded on rod member (3) and former welding hollowing ball (1).When rod member (3) transmits pulling force or pressure, ring-type ribbed stiffener (2) helps to undertake pulling force and pressure, thus strengthens Load-carrying capacity of welded hollow spherical.
Claims (3)
1. this utility model is a kind of welded hollow spherical joints, it is characterized in that: be uniformly arranged four identical ring-type ribbed stiffeners outside former solder sphere ball wall.
Welded hollow spherical joints the most according to claim 1, is characterized in that: ring-type ribbed stiffener width is 1/4th solder sphere diameters.
Welded hollow spherical joints the most according to claim 1, is characterized in that: ring-type ribbed stiffener thickness is identical with solder sphere wall thickness.
