Description
Technical Field
The invention relates to a node connection structure design, in particular to a welded hollow sphere node connected by steel inserting plates.
Background
The wood structure building becomes the first choice of the current green building with the advantages of green environmental protection, heat preservation, energy conservation, earthquake resistance, sound insulation and the like. The characteristics of the design standardization, the component factory production and the construction assembly are closely matched with the development trend of the assembly type building in China. In 2015, a scheme for promoting green building material production and application actions is jointly issued by the ministry of industry and informatization, the ministry of housing and urban and rural construction, and the scheme clearly proposes to vigorously develop the wood structure building. Compared to steel or cement based concrete, the construction of structural timber requires less energy and emits much less carbon dioxide to the atmosphere. The use of structural timber by itself or in combination with other building materials is therefore becoming increasingly popular with the aim of effectively reducing the adverse environmental impact of the construction industry. Over the past 30 years, engineered wood has been widely used in conjunction with reinforced concrete slabs to develop wood-concrete composite floors that improve the performance of structures in terms of vibration, ductility, fire resistance, etc. However, few have studied the combined use of structural wood and steel.
Due to the large span and the large size of the section of the member of the modern wood structure, the node design becomes a difficult problem. The construction of pure wood structure is limited by material characteristics, and the mechanical property advantages of concrete, steel and other materials can be utilized to complement wood, so as to provide an innovative wood mixed structure system. At present, steel-wood combined nodes, such as steel clamping plate bolt nodes, steel filling plate bolt nodes, bar planting nodes, adhesive bolt nodes and the like, are mainly adopted for large-span wood structure nodes. Compared with the traditional mortise and tenon joint, the modern wood structure joint has the advantages of convenience in processing, reliable performance, high rigidity, high bearing capacity and the like.
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, 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, and most of the structures of the building nodes in China still adopt the structural mode of a wood structure, the mode of bolt connection and the mode of rivet connection.

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 invention relates to a welded hollow ball joint connected by steel inserting plates, a hollow steel ball 4, wherein the surface of the hollow steel ball 4 is provided with a steel inserting plate 2, and a wood rod 1 is detachably connected with the hollow steel ball 4 through the steel inserting plate 2; the hollow steel ball 4 is respectively composed of two hollow hemispheres; the steel inserting plate 2 is welded with the surface of the hollow steel ball 4; the steel inserting plate 2 is in threaded connection with the wood rod 1 through a stud 3; the peg 3 may be a self-tapping screw.
The hollow steel ball 4 is formed by splicing and welding two hemispheres, so that the quality of a welding seam is critical, the process requirement cannot be met, and the first-level welding seam standard can be met; the steel inserting plate 2 is processed into an arc at one end and then is connected with the hollow steel ball 4 in a welding mode, and the load of the wood pole is transferred to the steel ball. The steel inserting plate 2 is provided with a hole which is connected with the wood pole 1 through a full thread self-tapping screw. The wood node is easy to tear and damage the wood, and the node reinforced by the self-tapping screw effectively inhibits the cracking of the wood due to the engaging force of the self-tapping screw; in order to reduce the node quality as much as possible and avoid the situation that the welding quality of the thick plate is difficult to guarantee, the hollow steel ball is not made of the thick plate.
The welded hollow ball joint connected by the steel inserting plate can be widely applied to joint design of a wood grid structure, the distribution of spherical stress is very clear, the positions with larger stress are all distributed around the ball shell at the joint of the steel inserting plate and the spherical surface, and the spherical stress far away from the weld toe falls rapidly along with the gradual distance of the spherical stress, which prompts that the stress of the ball body is characterized in that the mutual interaction effect of the hollow ball joints converged on a plurality of rod pieces under the action of multidirectional stress is very small, and the related action is small.
And secondly, the joint part of the wood rod, the steel inserting plate and the steel pipe is a weak link of the joint, and when the whole joint enters a plastic stage and continues to be loaded, the displacement of the joint is rapidly increased and the joint 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.
