Abstract
The utility model discloses a truss inner ring support node structure, which comprises a welded hemispherical support, wherein the lower half part of the welded hemispherical support is a steel pipe column structure, the upper end of the welded hemispherical support is provided with a plurality of truss a support stay bars uniformly distributed on the hemispherical surface, and the truss a support stay bars extend upwards in a divergent shape; and the plurality of truss a support stay bars and the welding hemispherical supports are connected with the intersecting nodes in an intersecting manner. The utility model discloses a this kind of truss inner ring support node structure adopts the hemisphere face as the support basis, evenly transmits the top atress for welding hemisphere support through many truss a support vaulting poles of form of dispersing to the structure of having guaranteed the steel truss can not receive the destruction.
Description
Technical Field
The utility model relates to a truss inner ring support node structure belongs to construction technical field.
Background
The stadium is the indoor building that carries out the sports match, and the sports is taken exercise or is held the concert, comprises stadium, stadium and grand stand three usually, and the plane is the ellipse, is the space steel pipe truss ceiling along the room lid around the stand. The steel awning is of a single space truss structure formed by a space pipe truss supported on a concrete column of the stand by a cantilever at the front end and a lattice truss column which is connected with the front end and falls to the two-layer platform, and the main trusses are connected through the circumferential space truss and the tensioning round steel support to form a space truss system together.
In the application process of the steel truss, the force applied to the steel truss is mainly transmitted to the bearing columns of the building through the support, so that the selection of the support is more important, when the bearing columns are inclined due to settlement or shake or incline due to factors such as earthquake and the like, the support acts on the steel truss, the structures of the support and the steel truss are damaged, and the safety of the whole building is further harmed.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a truss inner ring support node structure to overcome the not enough that exists among the above prior art.
The utility model discloses a realize like this:
a truss inner ring support node structure comprises a welded hemispherical support, the lower half part of the welded hemispherical support is of a steel pipe column structure, the upper end of the welded hemispherical support is welded with a hemispherical surface, a plurality of truss a support struts are uniformly distributed on the hemispherical surface, and the truss a support struts extend upwards in a divergent shape; and the plurality of truss a support stay bars and the welding hemispherical supports are connected with the intersecting nodes in an intersecting manner.
The utility model discloses a this kind of truss inner ring support node structure adopts the hemisphere face as the support basis, evenly transmits the top atress for welding hemisphere support through many truss a support vaulting poles of form of dispersing to the structure of having guaranteed the steel truss can not receive the destruction. The utility model discloses simple structure, it is convenient to be under construction, is worth promoting.
Drawings
Fig. 1 is a schematic structural view of the present invention;
fig. 2 is a sectional view taken along line a-a in fig. 1.
Description of reference numerals: 1-truss a support brace rod, 2-welding a hemispherical support and 3-intersecting node.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
As shown in fig. 1 and 2, a truss inner ring support node structure comprises a welded hemispherical support 2, the lower half part of the welded hemispherical support 2 is a steel pipe column structure, the upper end of the welded hemispherical support is welded with a hemispherical surface, a plurality of truss a support stay bars 1 are uniformly distributed on the hemispherical surface, and the truss a support stay bars 1 extend upwards in a divergent manner; the plurality of truss a support stay bars 1 are connected with the welding hemispherical supports 2 in a penetrating way to a penetrating node 3. The truss inner ring support node structure adopts a hemispherical surface as a support base, and the stress on the upper part is uniformly transmitted to the welding hemispherical support 2 through the divergent multiple truss a support stay bars 1, so that the structure of the steel truss is not damaged.
Of course, the above is only the specific application example of the present invention, and the present invention has other embodiments, and all technical solutions formed by equivalent replacement or equivalent transformation fall within the protection scope claimed by the present invention.
