Steel reinforcement is a common reinforcement in building materials. Reinforced concrete is one of the most widely used building components in the field of civil engineering, and the problem of corrosion of the steel bars inside the reinforced concrete is always concerned. For bridge structures, particularly coastal and cross-sea bridges, because the natural environment of the bridge structure at the position can accelerate the corrosion of reinforcing steel bars, the bridge structure faces many diseases, and the bridge piers in tidal range areas are particularly obvious. Compared with steel bars, fiber Reinforced composite (Fiber Reinforced Polymer, or Fiber Reinforced Plastic, FRP for short) bars have the following advantages: the reinforced fiber comprises Carbon Fiber (CFRP), glass Fiber (GFRP), basalt Fiber (BFRP) and Aramid Fiber (AFRP), and the adoption of FRP ribs to replace reinforcing steel bars is an effective scheme for solving the corrosion problem of the reinforced fiber.
The FRP ribs have the defects of linear elastic materials, brittle failure and the like, and besides CFRP ribs, the problem of low elastic modulus is particularly prominent, so that FRP-steel composite ribs, namely FRP wrapped outside the inner core steel bars, appear. The composite reinforcement not only avoids the corrosion of the reinforcement, but also solves the problems of various defects of the FRP reinforcement, has wide development prospect, but has poor machinability to block the further development of the FRP reinforcement, and particularly cannot be simply welded or mechanically connected like the reinforcement in the connection aspect. When the existing connection mode is adopted to connect two FRP-steel composite bars, the service life is short.
In view of this, 1-5, the present embodiment provides a reinforcement 10, the reinforcement 10 includes a structural member 100, a connecting member 200, and a grouting material 300.
The structural member 100 includes a first rod 110 and a second rod 120, and the first rod 110 and the second rod 120 are composite rods. The first rod member 110 includes a first reinforcing bar 111 and a first sleeve 112 covering the first reinforcing bar 111. The first steel bar 111 is a rod made of metal, and in this embodiment, the first steel bar 111 is a steel bar. The first sleeve 112 is made of Fiber Reinforced composite (Fiber Reinforced Polymer, or Fiber Reinforced Plastic, FRP for short), which has the following advantages: the composite material is corrosion-resistant, light, high in strength, fatigue-resistant and electromagnetic-insulating, wherein the reinforcing fibers comprise Carbon Fibers (CFRP), glass Fibers (GFRP), basalt Fibers (BFRP) and Aramid Fibers (AFRP). When the first sleeve 112 made of the fiber reinforced composite material is sleeved outside the first steel bar 111, the first rod 110 has high strength, rigidity and ductility, and also has good corrosion resistance, and the service life of the first rod 110 is longer. In this embodiment, the fibers of the first sleeve 112 extend along the axial direction of the first steel bar 111 (i.e. the length direction of the first steel bar 111) to enhance the load resistance.
In order to make the connection between the first reinforcing bars 111 and the first sleeve 112 more secure, in this embodiment, before the first sleeve 112 covers the first reinforcing bars 111 outside the first rod 110, the outer circumferential wall of the first reinforcing bars 111 may be sandblasted to make the outer circumferential wall of the first reinforcing bars 111 rough, so as to enhance the adhesion between the first sleeve 112 and the outer circumferential wall of the first reinforcing bars 111, and make the first sleeve 112 not easily separate from the first reinforcing bars 111.
To further prevent the first sleeve 112 from being separated from the first reinforcing bar 111, a protrusion may be further provided on the outer circumferential wall of the first reinforcing bar 111. After the outer peripheral wall of the first steel bar 111 is provided with the first sleeve 112, the protruding portion can give the first sleeve 112 a supporting force along the axial direction of the first steel bar 111, and the first sleeve 112 and the first steel bar 111 are prevented from being separated along the axial direction of the first steel bar 111.
The second rod 120 includes a second reinforcement bar 121 and a second sleeve 122 covering the second reinforcement bar 121. The second steel bars 121 are rod members made of metal, and specifically, in this embodiment, the second steel bars 121 are steel bars. The second sleeve 122 is made of a fiber reinforced composite material. When the second sleeve 122 made of the fiber reinforced composite material is disposed outside the second steel bar 121, the second rod 120 has high strength, rigidity, and ductility, and also has good corrosion resistance, and the second rod 120 has a longer service life.
In order to connect the second reinforcing bars 121 and the second sleeves 122 more firmly, in this embodiment, before the second sleeves 122 are disposed outside the second reinforcing bars 121 in the second rod 120, the outer circumferential wall of the second reinforcing bars 121 may be subjected to sand blasting to make the outer circumferential wall of the second reinforcing bars 121 rough, so as to enhance the adhesion between the second sleeves 122 and the outer circumferential wall of the second reinforcing bars 121, and make the second sleeves 122 not easily separate from the second reinforcing bars 121.
To further prevent the second sleeve 122 from being separated from the second reinforcement bar 121, a protrusion may be further provided on the outer circumferential wall of the second reinforcement bar 121. After the outer circumferential wall of the second steel bar 121 is sleeved with the second sleeve 122, the protrusion can provide the second sleeve 122 with a supporting force along the axial direction of the second steel bar 121, so as to prevent the second sleeve 122 and the second steel bar 121 from being separated along the axial direction of the second steel bar 121.
The connection member 200 is used to connect the first rod 110 and the second rod 120 so that the first rod 110 and the second rod 120 can be combined into a rod having a longer length. Specifically, the connection member 200 includes a metal pipe 210 and a third sleeve 220 covering the metal pipe 210. The metal pipe 210 is made of metal, and specifically, the metal pipe 210 may be made of the same material as the first steel bar 111 and the second steel bar 121. The third sleeve 220 may be made of a fiber reinforced composite material, and specifically, the third sleeve 220 may be made of the same material as the first sleeve 112 and the second sleeve 122. The fibers in the third sleeve 220 may extend in the axial direction of the metal pipe 210 to enhance the load resistance of the third sleeve 220.
Similarly, in order to improve the adhesion between the metal pipe 210 and the third sleeve 220, the outer wall surface of the metal pipe 210 may be sandblasted (so that the outer wall surface of the metal pipe 210 is provided with a rough layer), and then the third sleeve 220 may be provided on the outer peripheral wall of the metal pipe 210. And a convex portion may be further provided on the outer circumferential wall of the metal pipe 210, and the convex portion can give a supporting force to the third sleeve 220 in the axial direction of the metal pipe 210, and prevent the third sleeve 220 and the metal pipe 210 from being separated in the axial direction of the metal pipe 210.
In this embodiment, since the structure of the connection member 200 is substantially the same as that of the first pin 110, the greatest difference is that the metal pipe 210 has a cylindrical space at the center. Both the connection member 200 and the first pin 110 can be manufactured by substantially the same process, reducing the manufacturing cost. Specifically, in this embodiment, the processing processes of each component may be pultrusion processes of the FRP-steel composite reinforcement.
When the connecting member 200 connects the first rod 110 and the second rod 120, one end of the first rod 110 faces one end of the second rod 120 (for convenience of description, the end of the first rod 110 facing the second rod 120 is referred to as a first end, and the end of the second rod 120 facing the first rod 110 is referred to as a second end), and the axis of the first rod 110 and the axis of the second rod 120 are substantially overlapped. One end of the metal pipe 210 covers the first end of the first rod 110, and the other end of the metal pipe 210 covers the second end of the second rod 120. The grout 300 fills the gap between the metal pipe 210 and the first and second ends. After the grouting material 300 is coagulated and molded, the first rod 110, the second rod 120 and the connection member 200 can be fixed as a whole.
In the rib 10 of the embodiment, the grouting material 300 is used to fill the gap between the connecting member 200 and the first and second ends, so that the first rod 110, the second rod 120 and the connecting member 200 can be sufficiently stressed, and the metal tube 210 inside the connecting member 200 is made of a metal material, so that the connecting member 200 has better strength, rigidity and ductility, so that the connecting portion between the first rod 110 and the second rod 120 can bear larger stress, and the service life is prolonged. Meanwhile, the outer side of the metal pipe 210 is provided with the corrosion-resistant third sleeve 220, so that the connecting member 200 has better corrosion resistance, and the service life of the whole rib material 10 is further prolonged.
In this embodiment, the first sleeve 112 completely covers the outer peripheral wall of the first end, the second sleeve 122 completely covers the outer peripheral wall of the second end, and the third sleeve 220 completely covers the outer surface of the metal tube 210. So that the first sleeve 112 can protect the first end better, the second sleeve 122 can protect the second end better, and the third sleeve 220 can protect the metal tube 210 better.
The end wall of the first end (the end wall of the first rod 110 facing the second rod 120) may be in contact with or spaced apart from the end wall of the second end (the end wall of the second rod 120 facing the first rod 110). In this embodiment, the end wall of the first end is in contact with the end wall of the second end, which can make the connection between the first rod 110 and the second rod 120 more reliable.
The end wall of the first end and the end wall of the second end may be located at any position in the metal pipe 210 in the axial direction of the metal pipe 210. In this embodiment, the end wall of the first end and the end wall of the second end are in contact with each other and are located at the middle position of the metal tube 210, so that the stress between the connection member 200 and the first rod 110 and the second rod 120 is more balanced, and the connection effect of the connection member 200 is better.
In order to make the connection of the rib 10 more secure, in this embodiment, the metal portions of the end walls of the first end and the second end may be connected by metal, including welding, mechanical connection, and the like, and then the grouting material 300 is filled in the gap between the metal tube 210 and the first end and the second end.
In order to prevent the metal tube 210 and the grouting material 300 from generating relative displacement, in the present embodiment, the inner circumferential wall of the metal tube 210 is provided with an internal thread. The arrangement of the internal thread enables the metal pipe 210 and the grouting material 300 to be meshed after being coagulated and molded, so that the grouting material 300 can give a force to the metal pipe 210 along the axis direction of the metal pipe 210, and the metal pipe 210 and the grouting material 300 are prevented from generating relative displacement.
The number and the arrangement position of the internal threads in the metal tube 210 depend on actual requirements, and in the embodiment, two internal threads, namely a first internal thread 260 and a second internal thread 270, are disposed in the metal tube 210. The portion of the metal tube 210 opposite to the first end is provided with a first internal thread 260, and the portion of the metal tube 210 opposite to the second end is provided with a second internal thread 270. In this embodiment, the first female screw 260 and the second female screw 270 can prevent the relative displacement between the connection member 200 and the grout 300.
In addition to providing two internal threads, the first internal thread 260 and the second internal thread 270, in the metal pipe 210, the relative displacement between the grouting material 300 and the metal pipe 210 can be prevented by means of ribbing, welding a steel ring, and the like on the inner surface of the end of the metal pipe 210.
The grout 300 fills the gap between the metal pipe 210 and the first and second poles 110 and 120 by injection. In order to facilitate the injection of the grouting material 300, in the present embodiment, the connection member 200 is provided with a first hole 230, and the first hole 230 penetrates the metal pipe 210 and the third sleeve 220 in a direction perpendicular to the axial direction of the metal pipe 210. After the relative positions of the connection member 200, the first rod 110 and the second rod 120 are fixed, the grouting material 300 is introduced into the gap between the first hole 230 and the second hole.
In order to increase the introduction speed of the grouting material 300, in this embodiment, the connection member 200 is further provided with a second hole 240, the second hole 240 penetrates through the metal tube 210 and the third sleeve 220 along a direction perpendicular to the axial direction of the metal tube 210, the first hole 230 faces the first end, the second hole 240 faces the second end, and the hole axis of the first hole 230 is parallel to the hole axis of the second hole 240. The second hole 240 is provided to increase the introduction speed of the grouting material 300.
In another embodiment, the first hole 230 may be used for injecting material, the second hole 240 may be used for discharging material and exhausting gas, and when the grouting material 300 injected from the first hole 230 is discharged from the second hole 240, the grouting material may be terminated after the introduced grouting material 300 is considered to substantially meet the requirement. At this time, during the material injection, it is necessary to seal the ports at the two ends of the metal pipe 210 in the axial direction thereof with sealing members, so that the grouting material 300 can fill the gaps between the metal pipe 210, the first rod 110, and the second rod 120.
In this embodiment, the connection member 200 is further provided with a viewing hole 250, the viewing hole 250 penetrates the metal pipe 210 and the third sleeve 220 in a direction perpendicular to the axial direction of the metal pipe 210, and the viewing hole 250 is located between the first hole 230 and the second hole 240 in a direction parallel to the axial direction of the metal pipe 210. The observation hole 250 can discharge air between the first hole 230 and the second hole 240 in the metal pipe 210 when the first hole 230 and the second hole 240 are simultaneously injected, thereby increasing the injection speed. On the other hand, whether the grouting material 300 is completely injected and whether the gap between the metal pipe 210, the first rod 110 and the second rod 120 is filled can be observed. The observation hole 250 can also observe the alignment and contact of the first rod 110 and the second rod 120, and can also locate the position of the first rod 110 relative to the metal tube 210 and the position of the second rod 120 relative to the metal tube 210. In addition to positioning the position of the first rod 110 and the position of the second rod 120 relative to the sleeve 200 through the viewing hole 250, a middle position-limiting baffle or a stop lever can be placed at the position of the viewing hole 250 to position the positions of the first rod 110 and the second rod 120 relative to the metal tube 210 in a square manner.
In another embodiment, when the first hole 230 is used for injecting material and the second hole 240 is used for discharging material, the observation hole 250 needs to be covered by a transparent member to prevent the grouting material 300 from being led out from the observation hole 250.
In this embodiment, the hole axis of the viewing hole 250 is perpendicular to the hole axis of the first hole 230 and the hole axis of the second hole 240. In this scheme, the position of muscle material 10 is arranged when can being convenient for annotate the material, has promoted the convenience.
