Abstract
The invention relates to a joint for a unit type space truss and belongs to the technical field of E04 fixing construction. The present space truss has the defects of joint stress concentration, single space topological relation, non-unitization, and high design and manufacturing costs. A designer wants to construct the unit type space truss. A connecting mode of the joint of the unit type space truss is divided into longitudinal connection and lateral connection, wherein the thread connection is served as the longitudinal connection and the shaft hole connection is served as the lateral connection. A lateral rod piece is composed of two force rods, so that the stress concentration is reduced; meanwhile, the designer sets a position of a connecting point on the joint by referring to a diamond crystal structure; the stability of the structure is increased; and the joint is suitable for more space topological relation.
Description
Technical field
The present invention relates to a kind of joint of modular space truss, divide the technical field that belongs to the E04 fixed buildings by International Patent Classification (IPC) (ipc).As the joint of modular space truss, be applicable to finish the connection between the space truss rod member.
Background technology
Space truss mainly is divided into two large members, flat and sphere type at present.Famous space truss system has in the world, German MERO, Singapore RAMCO-YKK, Japanese NIPPON STEEL, U.S. STARNRT.These space truss system is an of great value invention with respect to original building structure, and it has realized large span effectively, the structure technology requirement of light dead-weight.But the architectural development trend that faces the future, existing space truss system still has some deficits, and it be difficult to solve quick simple designs, and joint part stress such as concentrates at the problem.Along with the human cost of structure design is more and more higher, modular space truss system also can more and more have superiority in market competition.
Summary of the invention
The object of the invention is to design a kind of joint of modular space truss system, solving the applicable multiple spatial topotaxy in same joint, joint part stress such as concentrates at the technical problem.
Technical scheme: the designer divides into vertical connection with the connected mode in the joint of modular space truss with main force's bar bearing of trend and is connected two kinds with side direction.The rod member that vertically connects adopts with the joint and is threaded, and the rod member that side direction connects adopts axis hole to be connected with the joint.Guarantee that the rod member that side direction connects is two power bars, subtract pauciarticular stress and concentrate.Simultaneously, the designer arranges the position of tie point on this joint with reference to the stationary atom structure of diamond crystal, improves on the one hand the stability of this joint institute commensurate structure, increases on the other hand the possibility that this joint adapts to more spatial topotaxies.
Architectural feature: this joint provides respectively one or more interfaces that are threaded longitudinally, the side direction annular arrangement one or more layers, one or more, symmetrical or asymmetrical axis hole connecting interface.The interface that is threaded in this joint can bear pressure and curved power in the structure behind overlap joint, and the axis hole connecting interface can bear pressure and torsion.
Beneficial effect: this joint can replace original ball-and-socket joint in practical engineering application, the two kinds of interfaces in this joint and arrangement mode can for building system more structures overlap joint is provided may.Multiple space overlapping mode can be realized in a kind of joint of interface arrangement mode, reduces the cost of processing step save design and manufacturing for the production in joint and design.
Description of drawings: the present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the arrange contour structures (vertically two hickeys, the double-deck Triaxial hole interface of side direction) of situation of a kind of interface in this joint.
Fig. 2 is a kind of overlapping mode that this joint cooperates the beam shape feature structure that rod member finishes.
Fig. 3 is a kind of overlapping mode that this joint cooperates the cylindricality feature structure that rod member finishes.
Fig. 4 is a kind of overlapping mode that this joint cooperates the sets of brackets on top of the columns feature structure that rod member and a kind of degree of freedom restriction system finish.
Claims (3)
1. the joint of a modular space truss provides respectively one or more interfaces that are threaded before and after main force's bar bearing of trend, main force's bar bearing of trend side direction annular arrangement one or more layers, one or more, symmetrical or asymmetrical axis hole connecting interface.
2. joint according to claim 1, it is characterized in that: on same joint according to the difference of transmitting power, the different rod member interface that distributes, a kind of is the interface that is threaded of anti-pressure and curved power, a kind of is the axis hole connecting interface that anti-pressure and torsion are avoided unidirectional curved power.
3. joint according to claim 1 is characterized in that: on the joint, the interface that is threaded, the side direction annular arrangement axis hole connecting interface of main force's bar bearing of trend are set on main force's bar bearing of trend.
