It is strong that above-mentioned screen fastener bears shock loads performance, and stabilized structure, does not affect the anticorrosive coat of Gate plate and base material, and easy accessibility.
On the double-screw bolt of interior connecting bolt, be also provided with spacing collar, disk is between spacing collar and the bolt head of interior connecting bolt.Can prevent like this loosening of interior connecting bolt, further strengthen the stability of fastener.
The above-mentioned center that is preferably located at disk through hole.Can further strengthen like this stability of fastener.
Hollow circular cylinder is 20-24mm deeply, and the diameter of disk is 4-6cm.Can further ensure like this stability of fastener.
Disk is provided with leaking hole.Can make like this rainwater etc. drain in time, the application life of extension fixture.
Preferably, leaking hole has 4, is relatively located between two on disk, and leaking hole aperture is 5-7mm.Like this ensureing in draining, steadiness that can assurance device.
The periphery of disk is provided with water delivery tank, and the groove depth of leaking water is 1-2mm, and wide is 1-2mm.Can further ensure that like this water can drain in time.
The bolt head of interior connecting bolt is provided with interior hexagonal.Can improve like this convenience of installing.
The double-screw bolt external diameter of interior connecting bolt is 10-12mm, and the internal diameter of hollow circular cylinder is 8-10mm.The stabilized structure of energy ensuring equipment like this.
The NM technology of the utility model is prior art.
This fastening system adopts exempts from welding design, has resistance to shock loads, the advantage being fastened securely; Fastening speed is installed fast, improves efficiency of construction; Good economy performance, does not affect girder steel anticorrosive coat, reusable.
