Description

Technical Field

[0001] This invention relates to the field of reconstituted bamboo component connection technology, and in particular to a rigid connection node for a reconstituted bamboo frame with adjustable angles for some of the rods. Background Technology

[0002] Bamboo is a fast-growing natural biomass building material with excellent mechanical properties. my country has abundant bamboo resources, which can meet the rapidly growing demand for building materials. However, as a natural material, the use of bamboo is limited by its geometric shape and physical properties, hindering its application and promotion in the construction field. With the development of industrial technology, existing processing techniques have developed various new bamboo composite materials. Among them, reconstituted bamboo is made by reorganizing raw bamboo, rolling it into filaments along the grain, and then drying, impregnating, assembling, and hot-pressing to form bamboo products. Compared with raw bamboo, reconstituted bamboo has higher load-bearing capacity and more reliable connection methods. Its special processing technology retains the mechanical properties of raw bamboo while overcoming its inherent defects.

[0003] During my country's past rapid development in the construction industry, steel and cement were the primary building materials used, leading to widespread skepticism about the application of reconstituted bamboo in building structures. Furthermore, the use of reconstituted bamboo as a novel material in structural construction is still in its early stages, with few mature structural systems currently available for practical engineering applications, hindering its widespread adoption. Therefore, despite its excellent mechanical properties, the primary applications of reconstituted bamboo are currently limited to home decoration and landscape architecture.

[0004] Typically, pin connections and steel connectors, or a combination of both, are used to assemble reconstituted bamboo structures. However, nodes relying solely on bolts and steel connectors require high installation precision, posing a significant challenge to on-site assembly techniques and hindering the engineering application of reconstituted bamboo. Currently, the angles of member connections are relatively fixed, but deviations during actual construction may not guarantee the expected angular accuracy, causing inconvenience. Furthermore, for ordinary bolted connections, the load-bearing capacity is mainly determined by the bearing strength of the pin groove, failing to fully utilize the strength of the reconstituted bamboo material, resulting in insufficient bending capacity and rotational stiffness of the nodes. To achieve effective moment transfer at reconstituted bamboo member connection nodes while facilitating construction, a structural form that does not require high on-site installation precision but enables rigid node connections is needed, thereby promoting the widespread application of reconstituted bamboo structures. Summary of the Invention

[0005] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a rigid connection node for a reconstituted bamboo frame with adjustable angles of some of the members. The installation accuracy can be reduced by welding between the steel connectors, and the steel connectors are bolted to the secondary members. It can be installed at various angles as required.

These components make the connection more stable and easier to connect.

[0007] According to the present invention, a rigid connection node for a reconstituted bamboo frame with partially adjustable rod angles is provided. A third steel plate connector is fixedly connected to the opening of the channel steel connector, and the first steel plate connector penetrates the third steel plate connector.
