Abstract

The utility model discloses a light steel pipe net rack node member which comprises a steel pipe net rack node steel pipe column and node connecting plates, wherein the node connecting plates are uniformly distributed and fixedly connected along the axis of the steel pipe net rack node steel pipe column, and are provided with connecting holes. As the connecting plates of the net rack nodes are uniformly distributed and fixedly arranged on the external circumference along the axis of the steel pipe net rack node steel pipe column, acting force applied by the slant bracing of all direction member bars on the nodes is uniformly applied on the centre line intersection point of the steel pipe column by the connecting plates of the net rack nodes so as to lead the steel pipe column to receive force more uniformly and reasonably, thus effectively avoiding lateral bending and torsion of the steel pipe column due to uneven stress, and guaranteeing the safety of the structure. The connecting plate of the net rack node adopts a semi-circular structure, and is applicable to various net rack structures, thus improving processing efficiency, being suitable for the connection of all nodes of a mainbody structure, and reducing complex procedures of manufacture and field installation. The light steel pipe net rack node member has the advantages of enough strength, rigidity and stability, better force-receiving and force-transfer, simpler and more convenient installation and dismounting, lighter weight and more convenient processing.

Description

A kind of light steel pipe rack node component
Technical field
The utility model relates to a kind of light steel pipe rack node component.
Background technology
Steel pipe frame structure joint form commonly used mainly comprises form of structure such as ordinary steel pipe support node, the solid steel pipe frame node of peace moral, space truss structure node in the current architecture configuration construction.Wherein ordinary steel pipe support node mainly comprises fastener type steel pipe frame and bowl fastening type steel pipe frame.Fastener type steel pipe frame connected node citation form has three kinds: right-angle coupler, rotary buckle and to clasp.Right-angle coupler is used for two steel pipes and is the square crossing connection; Rotary buckle is used for two steel pipes and is arbitrarily angled interconnection; The butt joint that clasp is used for two steel pipes connects.The center line of each rod member of ordinary steel pipe support node can not be intersected in a bit, and secondly, node connector is a foundry goods, the cost height.The solid steel pipe frame node of peace moral mainly is made up of the connector in spacer pin, termination connector and the vertical rod, the termination connector of cross bar and bearing diagonal is inserted in the connector of vertical rod in the steel pipe frame, spacer pin is inserted in the connector, its advantage is that structural-load-carrying capacity is strong, node connects efficient and convenient, but the center line of solid each rod member of steel pipe frame node of peace moral can not be intersected in a bit, and bearing diagonal is the eccentric structure member.Space truss structure node pattern mainly is the connection of solder sphere, bolt sphere, solder sphere, bolt sphere quality requirement height, welding, bolt are mainly taked in the connection of steel pipe, and welding, bolt are the emphasis of quality control in the construction and installation of steel tubular structure, thereby the cost of space truss structure is higher relatively.
Summary of the invention
For overcoming the defective that prior art exists, the utility model provides a kind of light steel pipe rack node component, can not be intersected in a bit and the more high relatively drawback of cost of space truss structure with the center line that solves each rod member of steel pipe grid node.
The utility model purpose is achieved in that this light steel pipe rack node component comprises steel pipe grid node steel pipe column and node junction plate, and described along the uniform node junction plate that is connected on the axis of steel pipe grid node steel pipe column, the node junction plate is provided with connecting hole.
The technological progress that the utility model is obtained: be packed in outer shroud along steel pipe grid node steel pipe column axis on week because the junction plate of this grid node is uniform, the active force that all directions rod member bearing diagonal applies on its node through the junction plate stepless action of grid node on the center line joint of steel pipe column, make steel pipe column stressed more evenly rationally, thereby effectively avoided lateral bending that steel pipe column causes because of discontinuity, reverse, thereby guaranteed the safety of structure.The junction plate of grid node adopts semicircular structure, applicable various space truss structure, junction plate is adopted unified radius size, not only improved the working (machining) efficiency of factory greatly, also can be applicable to the link of each position of joints of agent structure easily, pattern is unified substantially, reduce produce in factory and field erected complicated procedures of forming, can make main body structural steelwork total cost reduce by 3.1%, and have enough intensity, rigidity and stability, stressed, power transmission is better, installing/dismounting is easier, weight is lighter, processes more convenient.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is Fig. 1 user mode structural representation.
The specific embodiment
For further describing the utility model, be described further below in conjunction with accompanying drawing.
As shown in Figure 1, this light steel pipe rack node component is made of steel pipe grid node steel pipe column 1 and node junction plate 2, along the node junction plate 2 that is a semicircular structure of the uniform profile that is connected on the axis of steel pipe grid node steel pipe column 1, present embodiment node junction plate 2 is 4, and node junction plate 2 is provided with connecting hole 3.As shown in Figure 2, be the structural behavior schematic diagram behind the utility model connection bearing diagonal rod member 4,2 of bearing diagonal rod member 4 and node junction plates are connected.
Those skilled in the art or those skilled in the art are except that the quantity according to node junction plate 2 disclosed in the utility model and connected bearing diagonal rod member 4, also can take alternate manner outward, be set to corresponding or symmetrical 2,3,5 or 6 as node junction plate 2, on the node junction plate 2 in order to the quantity of the connecting hole 3 that connects bearing diagonal rod member 4 according to the construction requirement setting.These modes all should be understood in scope of the present utility model, are subjected to the restriction of the utility model claim.

Claims (3)
