Kev piav qhia
Lub tswv yim ntawm welded steel fabric / mesh yog thawj zaug npaj rau xyoo 1901, thaum thawj daim ntawv thov loj yog xyoo 1908. Hauv xyoo 1922, nws tau raug sim los ua cov khoom tsim nyog rau txoj kev tsheb loj. Thaum kawg ntawm Ntiaj Teb Tsov Rog II, nws tau pom nws lub zog vim tias nws yuav tsum tau ua haujlwm tsawg thiab sijhawm. Nws tau pom tias yog cov khoom siv txhawb zog zoo tshaj plaws los pab Tebchaws Europe rov tsim dua tom qab tsov rog. Ua ntej lub lem ntawm lub xyoo pua, nws tau txais raws li ib tug siv tau daim ntawv ntawm pob zeb reinforcement nyob rau hauv lub tsev. Nws kuj tau txais txiaj ntsig zoo hauv lwm cov haujlwm xws li tshav dav hlau khiav thiab ntau lub tsev tsim vaj tsev.
Qhov no reinforcement welded hlau mesh panels yog ua los ntawm ribbed steel tuav los ntawm qhov chaw vuam rau slab thiab phab ntsa. Cov ribbed steel pas nrig siv tau tuaj yeem txhim kho kev sib raug zoo rau cov pob zeb thiab txo qis cov pob zeb tawg uas yuav tshwm sim los ntawm kev ua vaj tse shrinkage. Cov yam ntxwv no ua rau cov ribbed steel weld mesh dav siv los ua cov khoom siv hauv tsev rau thaiv slab qauv reinforcing, thiab hollowed slabs reinforcement, lub tsev phab ntsa thiab txhawb phab ntsa. Hauv kev siv tswv yim, nws yog feem ntau siv nrog cov rooj zaum bar raws li kev txhawb nqa.
Cov ntaub ntawv thiab hom:
Ribbed steel bar mesh tuaj yeem muab faib ua peb hom raws li cov ntaub ntawv: Kub dipped galvanized, electro galvanized lossis stainless hlau. Nws tuaj yeem muab faib ua ob hom raws li steel bar qhov ntau thiab tsawg siv: hom hnyav (inch ntawm bar lossis pas nrig 12mm yam tsawg kawg nkaus) thiab lub teeb hom (inch ntawm rebar rods los ntawm 3mm txog 10mm). Ribbed steel welded mesh tuaj yeem muab faib ua lub qhov square thiab lub qhov sib npaug raws li qhov qhib hom.
