Abstract

The invention discloses a high-strength fiber reinforced composite material connecting piece and a formula and manufacturing process thereof. The connecting piece comprises an anchor fiber rod and aninjection molding intermediate body; a dovetail groove or a locking groove is formed in the anchor fiber rod; the injection molding intermediate body wraps the middle section of the anchor fiber rod;and a screw thread is disposed in the injection molding intermediate body. By changing the structures of the anchor fiber rod and the injection molding intermediate body, the contact area of the connecting piece and concrete can be greatly increased, and thus the drawing force is enhanced. The drawing force of the connecting piece can reach 15-20 kN; by changing the cross section shape of the anchor fiber rod, the stretching and bending degrees of the composite material are greatly improved; and the stretching strength of the connecting piece can reach 900-1100 MPa, and the bending strength ofthe connecting piece can reach 1000-1200 MPa.

Description

technical field

[0001] The invention relates to the technical field of construction, in particular to a high-strength fiber-reinforced composite material connector and its formula and manufacturing process. Background technique

[0002] The high-strength fiber-reinforced composite material connector is an intermediate used to ensure a tight connection between the insulation layer and the wall. At present, the connectors of Thermomass imported from the United States are mainly used in the market, and those produced in China also imitate the imported products. The final use is to connect the inner and outer walls and fasten the insulation layer. The structural design and production process are roughly the same. At present, there are still some defects in the design of the connectors. One is that the contact surface with the cement is not large enough, which will directly affect the pull-out force in the connection. Greatly degrades the overall performance of the joint. [00...
