Abstract
The utility model relates to a reinforcing steel bar mechanical anchor device, comprising reinforcing steel bars, and concrete blocks fixedly connected with the reinforcing steel bars; an anchor device is fixedly arranged at a pre-anchoring end of the reinforcing steel bars, the outer side or inner and outer sides of the anchor device are casted in the concrete; spiral bars or spiral grooves are rolled at the outer side of the anchor device by a rolling method. The reinforcing steel bar mechanical anchor device has simple and firm structure, the spiral grooves are rolled at the outer side of the anchor device by a rolling method, so as to lead the anchor device and the concrete to be reliably anchored; the anchor device is particularly suitable for anchoring of high strength reinforcing steel bars. The reinforcing steel bar mechanical anchor device is easy to be manufactured and implemented, the cost is saved, thus being beneficial to being popularized and implemented.
Description
One, technical field:
The utility model relates to the mechanical anchoring device in a kind of reinforced concrete structure, is specifically related to a kind of reinforcing steel bar machinery anchor device.
Two, background technology:
In order to guarantee the safety of reinforced concrete structure, reinforcing bar anchoring reliably is its necessary and sufficient condition, and the reliable anchorage length of reinforcing bar in concrete is by concrete strength and reinforced steel bar strength decision.By " The Concrete Structure Design regulation " GB 50010-2002 regulation, anchorage length of steel bar is generally got 30-40 times of bar diameter.
Along with the raising of reinforced steel bar strength can cause the growth of anchorage length, for example application of HRB500 grade reinforcing steel, the anchorage length of 25mm diameter reinforcing bar can reach 1250mm, and this will increase the risk of bonding failure, and causes the anchoring difficulty at beam, post node.
Three, utility model content:
The utility model is to overcome the deficiency that prior art exists, and designs and produce a kind of reinforcing steel bar machinery anchor device.
Technical scheme:
A kind of reinforcing steel bar machinery anchor device, comprise reinforcing bar, the concrete block of fixedlying connected with reinforcing bar is installed with an anchor device in the pre-anchored end of reinforcing bar, this anchor device outside or medial and lateral are cast in the concrete, and this anchor device outside has rolled out spiral bar or helicla flute by rolling depression method.
Described anchor device and affiliated reinforcing bar are by being threaded.
Described anchor device is cylindrical, perhaps is equilateral prismatic, perhaps is spherical.
Described anchor device is that No. 45 steel are made.
The beneficial effects of the utility model:
1, reinforcing steel bar machinery anchor device of the present utility model, it is simple in structure that firmly in order to make anchor device and concrete anchoring reliable, the anchor device external surface uses rolling depression method to roll out helicla flute, and this anchor device is particularly suitable for the anchoring of high strength cast iron.
2, reinforcing steel bar machinery anchor device of the present utility model is made easily and is implemented, and saves cost, is beneficial to very much promotion and implementation.
Four, description of drawings:
Fig. 1 is one of the utility model reinforcing steel bar machinery anchor device structural representation.
Five, specific embodiments:
Embodiment one: referring to Fig. 1, numbering 1 is a reinforcing bar among the figure, 2 is anchor device, and 3 is helicla flute, and 4 is screw thread, a kind of reinforcing steel bar machinery anchor device, comprise reinforcing bar 1, the concrete block of fixedlying connected with reinforcing bar is installed with an anchor device 2 in reinforcing bar 1 pre-anchored end, this anchor device outside is cast in the concrete, and these anchor device 2 outsides have rolled out helicla flute 3 by rolling depression method.
Described anchor device 2 is connected by screw thread 4 with affiliated steel 4 muscle.
Described anchor device is cylindrical, perhaps is equilateral prismatic, perhaps is spherical.
Described anchor device 2 is that No. 45 steel are made.
