As preferably, described press-in granule arrangement has concentric circular distribution, distributed rectangular, and press-in granule need to meet detailing requiments to bolt hole back gauge and ensure to fit tightly between steel plate, should be not less than 2 times that are pressed into particle diameter, wherein 3-5 times the most suitable.
As preferably, the press mode of described press-in granule can be divided into three kinds: (1), with released load after the vertical load extrusion indenture in resistant slide face, then tightens high-strength bolt.(2) extrude indenture with the vertical load in resistant slide face, tighten released load after high-strength bolt.(3) vertical load in resistant slide face is provided by high-strength bolt pretightning force, extrudes indenture on weathering steel surface when tightening high-strength bolt.
The present invention has the following advantages compared to existing technology:
1. there is the resistant slide performance of excellence, effectively solve the problem that weathering steel high-strength bolts resistant slide performance is not enough.Compared to conventional surface treatment technology, anti-slip coefficient doubles, and reaches more than 0.8.
2. simplifying construction technology, need not consider the roughness of steel contact surface, only need easy clean contact surface, be pressed into granule in advance and produce to stablize indenture around bolt hole, then tight a bolt the clamping by granule Yu indenture.Significantly reduce fabrication and processing difficulty so that it is be easier to promotion and application.
3. do not destroy weathering steel surface protection film, it is ensured that its service life.When surface near bolt is carried out Local treatment by conventional surface treatment technology such as wire drawing etc., its protecting film of destructible, its feature such as weather-proof can not be taken into account, thus reducing service life.And the present invention breaches the existing restriction forming effective anti-slipping property energy by connecting contact surface treatment, only it is pressed into several granules on surface, does not destroy weathering steel surface protection film, it is ensured that its service life.
