Abstract
The utility model relates to a spatial multiplexing K type node of a steel tube component, belonging to the field of building engineering. The node comprises a chord member and web members, wherein the value range of included angles between the chord member and the web members and between the web members is 30-150 degrees. When the web members and the chord member are both round steel tubes, the amount of the web members extending out from any outward side of the nodes of the round steel tubes is less than or equal to four times of a value obtained by rounding the ratio of the diameter of the chord member and the average diameter of the web members. When the chord member and the web members are both square steel tubes, rectangular steel tubes or diamond steel tubes, the amount of the web members extending out from any outward side of the nodes of the round steel tubes is less than or equal to four times of a value obtained by rounding the ratio of the cross section perimeter of the chord member and the average perimeter of the cross sections of the web members. In the utility model, transverse ribbed stiffeners are arranged along the radial direction in the chord member and the web members, and vertical ribbed stiffeners are arranged along the axial direction in the chord member and the web members. The utility model limits the amount of the web members and the included angle between the members, thereby ensuring that the stress of the whole node structure is more reasonable, and enhancing the stability of the structure.
Description
Technical field
The utility model relates to composite K type node of steel tube component space, belongs to building engineering field.
Background technology
Space structures obtains application more and more widely in construction work at present, especially being applied in the important buildings such as large span, high-intensity industrial premises, platform shed, stadiums more.Node is an ingredient important in the space structures, and space structures why can three-dimensional stressed, space behavior, and node plays a part crucial.The scope of geometric configuration, node panel thickness and the node thicker region of rationally definite node and the set-up mode of stiffening rib are the assurance safety of structure, improve stock utilization, effectively reduce one of key issue of steel using amount.And the complexity of node and bar cross section form are closely related, and rod member adopts pipe, square tube, rectangular tube uniform section form usually.
At present, the joint form ubiquity of steel tube component is following not enough in the domestic space structures:
1. joint form is comparatively simple, and it is bigger that chord member outer web member in node place stretches out the quantity limitation.
Joint form, structure, manufacture craft are occupied important status in the space structures subject, constantly bringing forth new ideas of joint form develops and just can play corresponding impetus to the development of space structures.And the joint form of steel tube component is comparatively simple in the present domestic space structures, and it is bigger that chord member outer web member in node place stretches out the quantity limitation, is difficult to tackle the node requirement of the complexity that may occur in the space structures engineering.
2. the space nodes form of square tube member seldom.
At present, because the pipe cross section is non-directional, most widely used general in space structures.Up to now, Chinese scholars has been carried out some researchs for pipe panel point etc., makes pipe trussed construction node technology obtain certain development.And square tube (rectangular tube) cross section is because high directivity is mainly used in plane frame, so the space nodes form of square tube member seldom.When the square tube truss in the space structures intersects, will have several rod members to meet at same node, geometrical relationship and stressed all very complicated, at this moment just need to adopt novel and also flexibly joint form finish crossing of each rod member.
The utility model content
In order to address the above problem, the utility model proposes a kind of composite K type node of steel tube component space.The utility model is optimized the quantity of angle between each rod member and web member, makes overall structure stressed more reasonable, can tackle the comparatively complicated node requirement that may occur in the space structures engineering.
To achieve these goals, the utility model has been taked following technical scheme.The utility model comprises chord member and web member, and web member is fixedlyed connected with chord member.The span of the angle between angle between chord member and the web member and web member and the web member is 30 degree～150 degree.
Described chord member and web member are round steel pipe, after web member quantity that the outside a certain side in round steel pipe node place is stretched out rounds smaller or equal to the ratio of chord member diameter and each web member average diameter 4 times.
Described chord member and web member are square steel pipe or rectangular steel pipe or rhombus steel pipe.After web member quantity that the outside a certain side in steel pipe node place is stretched out rounds smaller or equal to the ratio of chord member section girth and each web member cross section average perimeter 4 times.
In described chord member and web member, be disposed radially transverse stiffener, be provided with vertical stiffening rib vertically.
The utility model is compared with the node of general space structures steel tube component, the quantity of web member and the angle between each rod member are limited, the stressed of integral node structure more driven rationally, strengthened stability of structure, the comparatively complicated node requirement that may occur in the space structures engineering be can tackle, wider range of application and good prospects for application had.In addition, the utility model also is provided with transverse stiffener and vertical stiffening rib in rod member, guaranteed the local stability of member, form the bigger nodes domains of rigidity, the internal force of web member can effectively be transmitted, go for the situation that arbitrarily angled web member crosses like this, thereby avoided employing super large cast steel node.
