Assembly type wood structure reticulated shell pin connecting mechanism

Abstract

In order to solve the technical problems, the invention designs and assembles a pin connecting mechanism which is suitable for a multi-rod-piece crossed node in a large-span wood reticulated shell structure. The connecting mechanism comprises a specially-shaped steel connector, a continuous wood rod piece, a discontinuous wood rod piece, a through bolt and pins. The connecting mechanism is characterized in that the specially-shaped steel connector is formed by welding an overturned slotted part and four steel plates in an inclined crossed mode; and in order to facilitate accurate positioning and assembly on the spot, an upper row of reserved hole positions of the four steel plates is separately upwards formed with an opening. At a node joint, other wood rod pieces are discontinuous exceptthat one wood rod piece is kept continuous. According to the assembly type wood structure reticulated shell pin connecting mechanism disclosed by the invention, the connector is easily unified in specification, batch production can be realized, construction is convenient, the field mounting speed is low, the weight of a node part is relatively small, the exposed surface of a steel connector is relatively small, and the structural appearance shows a pure wood structure feeling while seen from bottom to top.

Description

technical field [0001] The invention relates to the field of building structures, and is mainly applied to multi-bar intersection joints in large-span wooden reticulated shell structures. Background technique [0002] Wood has many advantages such as greenness, environmental protection, and energy consumption reduction. my country is vigorously developing green buildings and vigorously advocating wood structures. It is of great significance for reducing energy consumption and protecting the environment, and it is also an important direction for future architectural development. [0003] Wooden structure refers to the engineering structure whose main force-bearing components are made of wood. With the advancement of modern technology and the improvement of people's living standards, modern wooden structures in China are also booming. The application range of wooden structures has expanded from traditional buildings to modern buildings. Breakthroughs have been made in terms of...

Problems solved by technology

[0004] The dome structure is one of the more classic structural forms in long-span wooden structures. The single-layer reticulated shell system is widely used. The nodes are important parts in long-span wooden structures. At present, the method of connecting nodes with the help of metal connectors has become a Mainstream, but most of them use steel hubs, steel splints or T-shaped embedded steel plates to connect wood components, which have high rigidity, and the metal parts are heavy and unsightly. In traditional connection methods, the metal connectors are usually exposed in the air. Not only is it poorly coordinated with the wooden atmosphere, but it also affects the durability of the steel. Therefore, the self-weight, construction speed, appearance and durability of the node parts of the long-span wooden structure need to be improved
