As preferably, described grooved rod is connected with fiber mesh muscle by structure glue and two ends elbow.
As preferably, described bow " type rod is connected with fiber mesh muscle by structure glue and two ends elbow.
As preferably, described " work " word rod is directly connected with fiber mesh muscle by structure glue.
As preferably, when connected mode adopts when vertical, described latch rod inserts fiber mesh muscle Nodes preformed hole by structure glue is connected with fiber mesh muscle; When connected mode adopts when oblique, described latch rod is directly connected with fiber mesh muscle by structure glue, or is formed through the preformed hole braiding of Nodes by fiber bundle resin pickup.
As preferably, described fiber mesh muscle and pitman are by fiber and resin solidification moulding, fiber comprises carbon fiber, glass fiber, basalt fibre, aramid fiber or hybridization fiber, be preferably carbon fiber, resin adopts unsaturated polyester (UP), vinylite, epoxy resin, phenolic resins and all kinds of structure glue, is preferably epoxy resin.
As preferably, described concrete is ordinary concrete, steel fibrous concrete, epoxy resin concrete, aqueous epoxy resins concrete or RPC.
Beneficial effect: the present invention by adding three-dimensional fiber grid muscle in concrete substrate, can in concrete, form the three-dimensional net structure running through continuously and mutually separately, the toughness that grid ribs has because of the concrete substrate mutually running through with it obtains toughness reinforcing, and concrete is because the skeleton rigidity carrying effect of fibrillar meshwork structure reinforcement is enhanced.Toughness and the cracking resistance that therefore can significantly improve the tension of concrete component and flexural strength, concrete component, can also alleviate construction weight, corrosion-resistant, electromagnetic shielding.Be applicable to the fields such as bridge board, road slab, building structure.
