Abstract
The invention discloses a friction type connecting method of a steel structure high-strength bolt based on a particle anti-slip effect, which does not need a special contact surface treatment process, and directly presses particles into steel plates connected by the high-strength bolt and then screws the high-strength bolt so as to improve the anti-slip coefficient of the high-strength bolt. The particles are pressed between the two connecting plates as required: the particles can be deformed but can not have cracks when pressed into the plate, and no gap is formed when the connecting plate is pressed. The particles need to meet specific mechanical properties and geometrical properties and are arranged around the high-strength bolt hole in a specific manner. The invention has low requirement on the surface of the connecting steel plate, directly presses the particles into the steel plate to form stable dents, tightly fixes the particles in the pressed dents by utilizing the pretension force of the high-strength bolt, prevents mutual slippage between contact surfaces by clamping and mutual limitation of the particles and the dents, obviously improves the anti-slippage coefficient of the high-strength bolt connecting contact surfaces, and simultaneously efficiently simplifies the surface treatment process of the component.
Description
Technical field
The invention belongs to field of civil engineering, be specifically related to a kind of steel structure high strength bolt friction-type connection method based on granule resistant slide effect.
Background technology
The anti-slip coefficient on high-strength bolt contact surface decides the frictional force size of connected plate, therefore uses during high-strength bolt the contact surface of component generally through special handling so that it is cleaning is also coarse, to improve its anti-slip coefficient.The existing Code for design of steel structures of China recommends the contact surface processing method adopted to include: sandblasting (ball), sandblasting (ball) are coated with inorganic zinc rich paint, sandblasting (ball) raw red rust afterwards afterwards, wire brush is removed floating rust or do not process.Ripe process of surface treatment can obtain the anti-slip coefficient of 0.3-0.5, but needs after plate sandblasting to assemble immediately to prevent surface from again getting rusty；It is coated with inorganic zinc rich paint after sandblasting and can reduce contact surface anti-slip coefficient, it is adaptable to outdoor structure such as science of bridge building but not high-rise building steel structure；After sandblasting, raw red rust need to consider the time of the getting rusty impact on coefficient of friction, needs again to remove floating rust during installation, and complex process and cycle are long.Additionally, contact surface is when moist or install when drenching with rain and will seriously reduce anti-slip coefficient, need strictly to avoid and ensure junction dry tack free in construction operation.Thus, develop a kind of new and effective high-strength bolts and become needs.
