Abstract
A prestress FRP rib screw pressurizing binding ground tackle comprises an anchor rod 2, a binding resin 3, a nut 4, a FRP rib or rope 7, wherein the anchor rod 2 is a cylinder, the external circle is provided with a thread and covered with a nut, the inside is provided with a cylindrical or a conical groove, the bottom of which is provided with a pore, the FRP rib or rope passes through the pore and is integrally positioned in the cylindrical or conical groove of the anchor rod, the groove is filled with binding resin 3. The utility model is characterized in that the anchor rod 2 of the ground tackle is inside provided with a pressure screw 1, the upper half in the anchor rod is provided with an internal thread, a sealing ring 6 is arranged at the bottom of the anchor rod, the outer rim of the pressure screw 1 is connected with the thread through the anchor rod. The ground tackle makes the binding resin firmly covered on the FRP rib or rope to combine the FRP rib or rope and the anchor rod as integration, thereby providing better anchor effect and higher carrying capacity than the FRP rib binding ground tackle without pressurizing, and no pressurizing equipment is required during implementation process. The utility model is of convenient construction and low cost.
Description
Technical field:
The utility model relates to a kind of presstressed reinforcing steel anchoring body device, particularly a kind of bond-anchorage body device of pre-stress FRP muscle.
Background technology:
Development along with prestressing technique, in building operations, set about research both at home and abroad and replaced common prestress wire with fibre reinforced composites (FRP) muscle or rope (hereinafter to be referred as FRP muscle or rope), because shearing resistance and the compressive strength of FRP are lower, as still continue to use existing structure intermediate plate anchor, will produce the stripped thread phenomenon or break the phenomenon of FRP muscle or rope.For this reason, the applicant applied for a series of pre-stress FRP muscle anchoring body device patents in 2002, wherein, and " the bond-anchorage body device of pre-stress FRP muscle " (number of patent application: 02242610.8) promptly be one of them; The bond-anchorage body device of this pre-stress FRP muscle is made up of pre-stress FRP muscle, anchor cup, binding resin, this anchor cup is the cylinder bodily form, screw thread is arranged on the periphery and be with nut, have taper or columniform groove in it, bottom land has an aperture, the pre-stress FRP muscle passes aperture, and integral body is arranged in the taper or the cylindrical groove of anchor cup, fills binding resin in the groove.Plurality of advantages such as this anchor device has the weather excellent, and antiseptic property is good, and the intensity height is in light weight, and the bulk life time of anchoring system is long.Its weak point is: the binding resin of perfusion in the raw, the one, have bubble, the 2nd, not too tight with contacting of pre-stress FRP muscle, influence anchoring effect; Secondly, the perfusion binding resin need use pressurized equipment, and it is not too convenient to construct, the cost height.
Summary of the invention:
The technical problems to be solved in the utility model is: existing pre-stress FRP muscle bond-anchorage body device perfusion binding resin need use pressurized equipment, and it is not too convenient to construct, the cost height; The binding resin of perfusion influences the problem of anchoring effect in the raw, and provide a kind of and need not use any pressurized equipment, easy construction, cost is low, the pre-stress FRP muscle screw rod pressurization bonding ground tackle that anchoring effect is better, supporting capacity is higher.
The technical scheme that solves its problems referred to above is: a kind of pre-stress FRP muscle screw rod pressurization bonding ground tackle, comprise the anchor cup, binding resin, nut, FRP muscle or rope, this anchor cup is the cylinder bodily form, screw thread is arranged on the periphery, and be with nut, have cylindrical or conical groove in it, bottom land has an aperture, FRP muscle or rope are worn small holes, integral body is arranged in the taper or the cylindrical groove of anchor cup, fill binding resin in the groove, it is characterized in that: a pressurization screw rod is arranged in the anchor cup of described ground tackle, and the first half has internal thread in the anchor cup, the bottom of anchor cup is equipped with a sealing ring, and outer rim and the anchor cup of pressurization screw rod are by being threaded.
Because a pressurization screw rod is arranged in the anchor cup of the utility model ground tackle, screw in the anchor cup less than the screw rod that will pressurize before solidifying at binding resin after filling binding resin, screw-in along with the pressurization screw rod, the volume of the binding resin in the anchor cup reduces and its pressure increase, thereby make binding resin closely knit and bond firmly on fibre reinforced composites (FRP) muscle or rope, FRP muscle or rope and anchor cup are combined as a whole, compare with the FRP muscle bonding ground tackle that does not have pressurization, it is better to have anchoring effect, supporting capacity is higher, and need not use any pressurized equipment in the implementation process, easy construction, low cost and other advantages.
Description of drawings:
Fig. 1～Fig. 2: the pre-stress FRP muscle screw rod pressurization bonding ground tackle structural representation of the utility model.
The specific embodiment:
Embodiment:
A kind of pre-stress FRP muscle screw rod pressurization bonding ground tackle, by pressurization screw rod 1, anchor cup 2, binding resin 3, nut 4, sealing ring 6, FRP muscle or rope 7 are formed, this anchor cup 2 is the cylinder bodily form, screw thread is arranged on the periphery, and be with nut 4, have columniform groove in it, bottom land has an aperture, FRP muscle or rope 7 pass aperture, and integral body is arranged in the cylindrical groove of anchor cup 2, fill binding resin 3 in the groove, one pressurization screw rod 1 is arranged in the anchor cup 2 of described ground tackle, the first halves have internal thread in the anchor cup 2, and the bottom of anchor cup is equipped with a sealing ring 6, and the outer rim of pressurization screw rod 1 and anchor cup 2 are by be threaded (referring to Fig. 1), among the figure, 5 is anchor plate.
As a kind of conversion of the utility model embodiment, the groove of opening in the described anchor cup 2 also can be that top is the conical tank (referring to Fig. 2) cylindrical, that the bottom is cone shape.
In the various embodiments described above, described binding resin 3 is the modified epoxies with toughness reinforcing, fast hard, enhancing, anti-aging function.
Described sealing ring 6 adopts Y
xShape or O shape circle.
