The utility model discloses a welding ball node is as whole support to structural feature according to truss last chord corner sets up truss an main chord member and truss an web member, can be convenient for high efficiency realize the truss in the connection of last chord position.
Description
Technical Field
The utility model relates to a truss chord angle department connected node 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.
The overall projection of the stadium steel structure is similar to an ellipse, one is the largest in the span and the other is the smallest in the span. The steel structure column end is connected with the spherical steel support. The steel pipe connecting joints are round pipe intersecting joints and ball pipe joints. The steel structure awning is composed of a plurality of main trusses, a plurality of annular truss units and a plurality of supporting units. The main truss is divided into two parts, one part is a lattice column, and the other part is a truss girder.
Due to large engineering quantity and complex construction procedures, the construction environment and the operation conditions in the construction implementation stage are considered, the structure construction is completed within a set construction period, and the difficulty is very high. Because the main difficulty of the stadium is the construction of the steel truss, how to construct the steel truss structure of the stadium is an important technical scheme for solving the technical problem of the construction of the stadium.
In the prior art, utility model patent CN110541365A applied by eight offices of central construction, fourth construction limited company discloses a construction method of a multi-layer steel truss building, comprising: arranging a plurality of reinforced concrete pedestals on the ground in the area corresponding to the steel truss to be arranged; arranging a support frame for bearing the load of the steel truss on the reinforced concrete base, wherein the support frame extends upwards to the bottom of the bottom steel truss; the steel trusses from the bottom layer to the top layer are sequentially arranged on the support frame from bottom to top, the steel trusses are integrally connected with the main body frames on the two sides of the steel trusses, and the main body frames on the two sides of the steel trusses are constructed from bottom to top before or while the steel trusses are arranged; through set up the support frame in steel truss below, the support frame can provide the support for the steel truss of treating the construction for the installation of steel truss can go on in step with the construction of both sides main body frame in the middle of the building.
In addition, a utility model CN107254917A applied by the southeast Net frame of Zhejiang province Limited company discloses an ultra-large span multi-stage prestressed steel truss structure and a construction method thereof, which comprises a steel truss and a double-cable lower chord node fastening device, the bottom parts of the two ends of the steel truss are respectively provided with a universal ball hinged joint, a plurality of continuously distributed double-cable lower chord joint fastening devices are arranged below the steel truss, the steel truss and the double-cable lower chord node fastening device are positioned through a V-shaped stay bar, two ends below the steel truss are respectively provided with a multi-directional cable cross fixing node, the steel truss and the multi-directional cable cross fixing node are positioned through the multi-chord supporting rod, the double-cable lower chord node fastening device, the steel truss and the multi-directional cable cross fixing node are positioned through the main chord double pulling cable, and the multi-directional cable cross fixing node and the steel truss are positioned through the inclined pulling cable.
For the truss connection node, the technical difficulty of the truss connection node at the corner, especially the upper and lower chord corners, is often high, so the design of the steel truss node connection structure at the upper and lower chord corners is very important for the steel truss construction, however, no ideal scheme is provided for the technology in the prior art.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a truss last quarter corner connected node to overcome the not enough that exists among the above prior art.
The utility model discloses a realize like this:
a truss upper chord corner connecting node comprises a welding ball node, wherein three truss a web members are arranged on the welding ball node, the extending directions of the three truss a web members are positioned on a plane, and the included angle of two adjacent truss a web members is 50-70 degrees; two truss a main chords are oppositely arranged in the direction orthogonal to the plane formed by the three truss a web members.
The utility model discloses a welding ball node is as whole support to structural feature according to truss last chord corner sets up truss an main chord member and truss an web member, can be convenient for high efficiency realize the truss in the connection of last chord position. The utility model discloses a truss last quarter corner connected node can be applied to such as during large-scale building steel construction connection such as gymnasium, stadium well, simple structure moreover, and the construction is swift, is worth promoting.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Description of reference numerals: 1-welding a ball joint, 2-truss a main chord member and 3-truss a web member.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
As shown in fig. 1, the truss upper chord corner connecting node comprises a welding ball node 1, three truss a web members 3 are arranged on the welding ball node 1, the extending directions of the three truss a web members 3 are positioned on a plane, and the included angle between two adjacent truss a web members 3 is 50-70 degrees; two truss a main chords 2 are provided in opposition to each other in a direction orthogonal to a plane formed by the three truss a web members 3.
The utility model discloses regard as the base with welding ball node 1 during implementation, connect truss an web member 3 and truss an owner chord member 2 respectively according to last chord truss characteristics, until accomplishing the truss connection of whole truss last quarter corner position.
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.
