GFRP Dowel Bars Rau Pob Zeb Pavements

   GFRP dowel bars for Concrete Pavements are typically Grade 60 (ASTM A615) plain uncoated steel or coated steel (zinc galvanized, epoxy or other coating material) of various cross sectional areas to accommodate anticipated loads.

Nyob rau hauv kev tsim kho ntawm pob zeb slabs, txawm nyob rau hauv qib, elevated, los yog lwm yam, pob qij txha, paub los ntawm xws terminology li expansion, contraction, thiab lwm yam, yog lub hom phiaj nyob rau hauv lub slab los tswj qhov chaw tawg nyob rau hauv, los yog txav ntawm lub slab yuav tshwm sim. Cov pob qij txha no tuaj yeem raug txiav rau hauv cov pob zeb tom qab cov khoom siv pob zeb tau muab tso thiab ua kom tawv, rau hauv cov pob zeb thaum lub sij hawm tso, los yog txhais los ntawm ntau yam kev sib koom ua cov ntaub ntawv uas tau muab tso ua ntej qhov kev tso kawm.

Qee qhov xwm txheej, cov khoom siv sib txuas sib txuas ua ke, dowel tuav, raug pov rau hauv cov slabs kom lub dowel bar longitudinal center yog nruab nrab taw tes longitudinally ntawm qhov sib koom ua ke. Cov khoom siv no ua haujlwm, feem ntau, txwv kev txav ntsug ntawm cov slabs uas nyob ib sab, thaum tso cai rau cov slab txav mus rau kab rov tav. Dowel tuav, Txheej rau tam sim no, steel, dowel tuav thiab dowel baskets yog los tiv thaiv, los yog forestall corrosion, xeb, ntawm cov hlau vim ib puag ncig los yog project tej yam kev mob.

Khoom yam ntxwv thiab kev thov

1. Tsis muaj qhov tsis zoo, tawg rau ntawm qhov chaw thiab sab hauv, txhua lub bar xim xim (ntsuab lossis lub teeb daj).

2. tuaj yeem tiv taus cov sawing, milling, npaj, drilling, tshuab dhos thiab lwm yam kev ua haujlwm.

3. Nws muaj damping zoo, creep tsis kam, qaug zog tsis kam, tawg tsis kam, kub tsis kam, kev nyuaj siab corrosion thiab lwm yam.

Khoom Parameter (specification) ntawm pob zeb pavement dowels

Khoom feature thiab daim ntawv thov ntawm FRP Dowel bar

Pulwell fiberglass dowel bar yog cov lus teb rau cov lus hais saum toj no. Iav Fiber Reinforced Polymer (GFRP) Dowel Bars muaj ntau qhov zoo thaum siv los ua cov khoom siv thauj khoom thauj mus rau txoj kev taug mus ntev. Lub Achilles Heel ntawm pob zeb pavement yog qhov sib koom ua ke. Kev sib koom tsis ua haujlwm feem ntau yog tshwm sim los ntawm corrosion ntawm steel dowel bar. Pulwell Dowel tuav yuav tsis xeb los yog corrode, xauv ib qho kev sib koom ua ke los yog ua rau spalling ntawm cov pob zeb ib puag ncig. Tsis tas li ntawd, thaum muab qhov tsim nyog shear peev xwm ntawm qhov sib koom ua ke, qhov qis qis ntawm GFRP Dowel tuav txo qhov qaug zog ntawm cov pob zeb nyob ib puag ncig lub dowel.

Cov txiaj ntsig ntawm Pulwell Dowel tuav

1.Impervious rau Chloride Ion thiab tshuaj tua kab mob

2. 1/4 qhov hnyav ntawm tsoos steel dowels txhais tau tias:

Kev tuav tau yooj yim dua

Tsawg dua kev raug mob

Kev txhim kho sai dua

3. Modulus ntawm Elasticity ze rau pob zeb dua li cov hlau

Tsawg kev ntxhov siab hauv pob zeb nyob ib ncig ntawm lub dowel

Tso cai rau qis zog pob zeb

4. Tsis tas yuav Grease Dowels

Lub cev muaj zog ntawmCorrosion pov thawj Dowel bar
