Concrete wedge anchors the bolt rod is provided with two expansion pipes, so that there is a fracture squeeze and friction area between the anchor bolt and the concrete hole wall, thereby inserting the plastic deformation of the steel and concrete.
The threaded tooth surfaces at both ends of the expansion tube may have the effect of engaging the pressing surface of the hole wall.
The “spring” action of the expansion tube in the radial direction, the bolt is controlled by itself when the alternate anchor bolt is installed
The lever can only move unidirectionally towards the bottom of the hole.
The tooth surface of the outer thread of the expansion tube can be significantly reduced concrete wedge anchors Attenuation of anchoring force and pull-out slip, and effectively improve the performance of anchor bolts under dynamic load and combined load.
Compared with existing similar products under the same conditions concrete wedge anchors The overall performance is more stable, the loss of anchoring efficiency is less, the structure is simpler, the processing difficulty is less, and the performance price ratio is higher. Using thick standard nuts and flat washers, bolts and expansion tubes are produced from high-strength alloy steel hot-rolled rods. The strength of the steel is 10.9, and the thickness of the galvanized layer is 20-20 μm for harsh environments, 13-15 μm for medium environments. Good The environment is 8-10 μm. According to actual needs, fixdex concrete wedge anchors can also be produced using other steel or stainless steel with comparable performance.
Fixdex concrete wedge anchors The concrete bore used is the same as the outer diameter of the product. When installing the anchor bolt, the diameter of the expansion pipe is reduced after being squeezed by the hole wall and squeezed into the hole with the bolt rod. When tightening the nut to pre-tighten the anchor bolt, the bolt rod moves out of the hole. Because the resistance of the taper surface of the bolt rod entering the expansion tube is less than the frictional resistance between the expansion tube and the hole wall, the bolt rod cone surface is squeezed into the expansion tube to force it to expand into the hole wall. Taper hole, combined effect makes anchor bolt produce strong anchoring force. The fixdex anchor has both the anchoring mechanism of expansion and reaming of the same type of anchor. The larger the pull force of the Wedge anchor / Through bolt, the more obvious the subsequent expansion of the expansion tube, and the stronger the anchoring effect of the anchor bolt.
Scope of application
concrete wedge anchors It is a new product for high-strength and heavy-duty building anchors. It is suitable for the connection of reinforced concrete structures, hard stone and steel structures (profiles, equipment, embedded parts, accessories) under stress. For example: installation of steel frames for curtain walls (aluminum-plastic panels, dry-hanging stone), installation of heavy equipment such as elevators, power distribution cabinets, large ducts, heavy-duty shelves, civil air defense doors, fire stairs and machine tools, installation of grid roofs, Load-bearing members such as steel corbels, steel structures and additional layers, steel plate embedded parts, reinforced steel plates, high-speed road crash barriers and large-scale advertising, municipal, railway, highway signage and other metal accessories
