Description

Technical Field

[0001] This utility model relates to a node connection structure, specifically a node connection structure for a raw bamboo structure, and belongs to the field of architecture and civil engineering. Background Technology

[0002] 1. Patent Title: A Cross-Connector for Raw Bamboo; Application Number: CN 211395986 U

[0003] A cross-connector for raw bamboo includes a base plate and positioning stakes. The base plate is horizontally arranged, and the positioning stakes are vertically arranged cylindrical shapes located on the upper side of the base plate. The positioning stakes have several first through holes arranged vertically at intervals and penetrating radially. The axes of these first through holes are staggered. Each first through hole contains a limiting screw, with both ends of the limiting screw extending beyond the first through hole. The base plate extends circumferentially beyond the positioning stakes. The base plate has several second through holes arranged vertically around the positioning stakes. Each second through hole contains a vertically arranged adjusting screw. An adjusting nut is screwed onto the upper and lower sides of the base plate corresponding to the position of the adjusting screw. Two adjusting nuts are clamped on both sides of the base plate. At least one clamp is located on the lower side of the base plate. This connector is used for cross-connecting raw bamboo, featuring a simple structure, convenient operation, stable and reliable connection, and an aesthetically pleasing appearance. The clamps can also be removed to extend the length of the raw bamboo.

[0004] 2. Patent Title: A Joint Connection Structure for Raw Bamboo Structure; Application Number: CN 214006024 U

[0005] A joint connection structure for raw bamboo includes raw bamboo, connectors, and bolts. The connectors are one or more types, such as straight connectors and cross connectors. The raw bamboo is inserted into the inner cavity of the connector. At least one bolt is perpendicularly installed on the side of the connector, penetrating the raw bamboo and connecting them. The gap between the outer wall of the raw bamboo and the inner wall of the connector is filled with adhesive, and a rubber ring is placed on the outer end face of the gap to block and prevent adhesive leakage. The joint connection structure provided by this utility model is easy to assemble. The straight connectors and cross connectors are connected to each other using ear plates, with arbitrary angles and flexible connections. The lightweight internal filling suppresses local buckling of the raw bamboo inward, effectively transferring the force of the joint and ensuring the connection effect of strong joints.

[0006] The above technologies have basically solved the problem of vertical and angular cross-connection of raw bamboo, but they do not take into account the hinge performance of the connection nodes, which may lead to unreasonable mechanical transmission, inability to adapt to deformation and insufficient structural stability. They also do not take into account the convenient adaptation of raw bamboo with different diameters, which may lead to problems such as complicated construction and waste of materials. Summary of the Invention

[0007] The technical problem to be solved by this utility model is to provide a cross-connector for raw bamboo, which is used for cross-connection of raw bamboo. It aims to solve the problem of reasonable mechanical transmission of cross-connection nodes of raw bamboo and adapt to deformation to ensure the stability of the overall structure. In addition, it also aims to provide a convenient and adaptable method for raw bamboo with different diameters.

[0008] 1. A connecting node component for intersecting raw bamboo, characterized in that it comprises: a raw bamboo, with concrete poured at one end and bolts prefabricated in the concrete; a factory-prefabricated metal part with screw grooves and arc-shaped joints, wherein the raw bamboo and bolts with bolt caps are screwed into the metal part with screw grooves; two semi-circular metal combined sleeves, wherein a second raw bamboo is placed inside the metal combined sleeves; and a plastic gasket, wherein the plastic gasket is attached to the inner wall of the metal combined sleeves to ensure that the second raw bamboo is tightly fitted to the metal combined sleeves.

[0009] 2. According to the above-mentioned connecting node component for cross-shaped raw bamboo, the metal combination sleeve is characterized in that: the diameter of the metal combination sleeve can be adjusted within a certain range, and by adjusting the diameter of the metal combination sleeve, the plastic gasket can be tightly attached to the surface of raw bamboo of different diameters, thereby achieving a stable connection of raw bamboo of different diameters.

[0010] In bamboo construction, the metal plates at the joints where bamboo stalks intersect feature a unique and ingenious design. The use of curved and semi-curved shapes is a significant design consideration. When the bamboo is affected by external environmental factors, such as wind, slight vibrations, or thermal expansion and contraction due to temperature changes, the curved or semi-curved structure of the metal plates allows the bamboo to move slightly within a certain range. This slight movement prevents excessive stress concentration caused by rigid connections when facing various external forces and natural changes, thus avoiding damage and cracking of the bamboo. This effectively improves the stability and durability of the entire bamboo structure, allowing it to better adapt to different working conditions and ensuring the normal functioning of its overall structure.

[0011] The metal fittings used for cross-connecting raw bamboo utilize adjustable-diameter metal sleeves and internal plastic gaskets. In practical applications of raw bamboo construction, the diameter of raw bamboo often varies. Using conventional fixed-size connectors would present numerous inconveniences and compatibility issues. However, the adjustable-diameter metal sleeve effectively solves this problem. It can be adjusted according to the specific diameter of the raw bamboo. Whether the diameter is large or small, a simple adjustment of the metal sleeve's diameter ensures the gasket fits tightly against the bamboo surface, achieving a secure connection. In this way, a single component can meet the connection needs of raw bamboo of different diameters, significantly improving construction efficiency, reducing the hassle of preparing multiple connectors of different sizes due to variations in bamboo diameter, and also lowering costs to some extent. This makes raw bamboo construction more convenient, efficient, and economical in actual construction. Attached Figure Description
