Description
Technical Field
The invention relates to a joint connection structure design, in particular to a steel-wood combined joint connected by steel sleeves.
Background
In an actual reticulated shell structure, a spherical joint is often acted by a multidirectional axial force, and when the load of a branch pipe is small, the multidirectional stress state is close to the one-way stress state of a main pipe. The unidirectional compression is slightly higher than the multidirectional compression bearing capacity, but the difference is not large, and the multidirectional compression is mainly unidirectional. The current specifications do not specify the multidirectional stress performance and the node connection mode of the node, and the research on the aspect is yet to be further developed.
With the development of modern technology and the improvement of living requirements of people, the wood structure begins to develop towards a large-span and multi-story high-rise direction, the connecting node of the wood structure often needs higher rigidity and can bear larger bending moment and shearing force, and the traditional connecting mode such as mortise-tenon connection and the like can not meet the requirements. Due to the complexity of the node form, the traditional nodes such as the adhesive bolt nodes cause uncertainty of the bearing capacity value of the node in the actual design. In fact, for a specific node instance, there should be a corresponding bearing capacity design guidance formula. However, the node forms in the general design rules are simple and cannot be accurately applied to some specific node forms used in the project design.
The wood members are mainly connected through pin type shear parts, the lateral stiffness of the structure is low, and the node can be damaged by transverse grain splitting of wood. Therefore, the connection mode of the wood members in the wood structure, the connection form between the wood and the concrete or steel and the cooperative working mechanism are also the key points of the research of the wood structure.
Currently, research and discussion on the composite structure of the two components is limited to the performance analysis of the single component. The structural composition form is mostly that steel is used as a plate member, and a wood structure is arranged on two sides and connected with a steel member through bolts or rivets to play a supporting role. The main difficult problem of the two composite structures is the research on the nodes, the research on the problem is not mature at present, and the importance of the node problem lies in the improvement of the seismic performance and the integral stability of the node on the whole structure. The construction of domestic building nodes mostly still continues to use the construction mode of wood structures, bolt connection and rivet connection.
Disclosure of Invention
In order to solve the problem, the invention provides a steel-wood combined node connected by steel sleeves, which can be widely applied to the structure of a wood latticed shell to enable a building to have very effective ductility and energy consumption capability.
In order to solve the technical problems, the technical scheme adopted by the invention is as follows: the steel-wood combined node comprises a hollow ball, wherein a steel sleeve is arranged on the hollow ball, the steel sleeve and the hollow ball are detachably connected, a plurality of wood rods are arranged, and the wood rods are connected with the hollow ball through the steel sleeve.
Preferably, the edge of the steel sleeve is an arc-shaped groove, the steel sleeve is attached to the hollow ball through the arc-shaped groove, and the attachment position is welded.
Preferably, the steel sleeve is detachably connected with the wooden pole through a stud.
Preferably, the hollow ball is formed by combining and welding two steel hemispheres.
Preferably, the peg is a self-tapping screw.
The steel-wood combined node connected by the steel sleeve can achieve the following beneficial effects:
1) the manufacturing process is simple, the construction is fast, the steel sleeve and the hollow ball are easy to manufacture, and the construction difficulty is greatly reduced.
2) The integral rigidity of the node is high due to the embedding effect of the steel sleeve, load can be effectively transmitted to the hollow ball through the stud, the embedding effect can reduce the influence caused by random defects such as wood knots, and the like, and therefore the tensile strength of the node is improved. This also enables the node to bear a larger load and a larger span than a conventional node; the steel-wood combined node connection has better ductility.

FIG. 2 is a schematic structural diagram of a hollow sphere of the present invention;
fig. 3 is a schematic structural view of a steel sleeve of the present invention.
Description of the drawings: 1. a wood pole; 2. a steel sleeve; 3. a stud; 4. the hollow ball.
Detailed Description
The invention is further described below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
The steel-wood combined node connected by the steel sleeves can be widely applied to a wood latticed shell structure and comprises hollow spheres 4, the hollow spheres 4 are provided with the steel sleeves 2, the steel sleeves 2 are detachably connected with the hollow spheres 4, a plurality of wood rods 1 are arranged, and the wood rods 1 are connected with the hollow spheres 4 through the steel sleeves 2; the edge of the steel sleeve 2 is an arc-shaped groove, the steel sleeve 2 is attached to the hollow ball 4 through the arc-shaped groove, and the attached part is welded; the steel sleeve 2 is detachably connected with the wood rod 1 through a stud 3; the hollow ball 4 is formed by combining and welding two steel hemispheres; the stud 3 is a self-tapping screw.
The spherical stress distribution is very clear, the positions with larger stress are all distributed around the spherical shell at the joint of the steel inserting plate and the spherical surface, and the spherical stress far away from the welding position falls off sharply along with the distance, which prompts that the stress of the spherical body has the characteristics of small mutual interaction effect and small related action on the joint of a plurality of rods under the action of multidirectional stress.
The joint of the wood rod, the steel sleeve and the steel pipe is a weak link of the node, and when the node integrally enters a plastic stage and continues to be loaded, the node displacement is rapidly increased and enters a plastic failure state. Therefore, the node design should be left with sufficient margin so that the node is safe and reliable. The full-thread self-tapping screw has an obvious effect on reinforcing the strength of the node.
The above is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
