Description

Bolt assembly for connecting plates

Technical Field

The utility model belongs to the technical field of hardware fitting, concretely relates to bolt assembly is used in panel connection.

Background

The wood connection is a key part of a wood structure, the requirements of design and construction are strict, the force transmission is clear, the toughness and the tightness are good, the structure is simple, and the inspection and the manufacture are convenient. Common connection methods include mortise and tenon joint, wood structure connection, tooth connection, bolt connection and nail connection. The mortise-tenon joint is characterized in that the timber is utilized to bear and transmit force so as to simplify the structure of beam-column connection; the mortise and tenon embedding effect is utilized, so that the structure has certain adaptability when bearing horizontal external force. The wood structure connection is also called adhesive connection, is still widely applied to the traditional wood structure building in China so far, and has the defects of large weakening of the stress area of wood and low economy of materials. The tooth connection is used for the connection mode of the truss node, the end of the pressure lever is made into a tooth shape and directly propped in the tooth groove of the other rod piece, and the pressure is borne and the force is transferred by the wood. The bolt connection and the nail connection are in a wood structure, the working principle of the bolt and the nail is the same, namely the bolt and the nail are pressed by wood on the hole wall of the bolt and the nail due to the fact that the relative movement of the components is prevented, the bolt and the nail are sheared and bent, and the wood is sheared and split. In order to fully utilize the good flexibility of bending of the bolts and the nails and extrusion of the wood, the problem that the wood is sheared and broken or split due to too thick bolts and nails, too dense arrangement or too thin members is avoided. There are provisions in construction for minimum thickness of timber, minimum spacing of the bolts and nails. At present, when two blocks of panels need the right angle mode to be combined, often adopt self tapping screw or trinity connection eccentric wheel screw to install, it is inconvenient to dismantle easily on the one hand, and on the other hand installation is insecure, seam easily behind the long-term atress.
