三(san)、使用方法

1、在現場檢測墻體時采用擺(bai)動(dong)沖擊(ji)，將(jiang)掛球(qiu)(qiu)(qiu)架立(li)于墻邊(bian)，調整好高(gao)度(du)(du)(du)，使球(qiu)(qiu)(qiu)體中(zhong)心點(dian)對正沖擊(ji)點(dian)，將(jiang)抓(zhua)球(qiu)(qiu)(qiu)架立(li)在旁邊(bian)，抓(zhua)球(qiu)(qiu)(qiu)裝(zhuang)置高(gao)度(du)(du)(du)對應在掛球(qiu)(qiu)(qiu)架上的刻(ke)(ke)度(du)(du)(du)位置，高(gao)刻(ke)(ke)度(du)(du)(du)距(ju)(ju)球(qiu)(qiu)(qiu)沖擊(ji)中(zhong)心1.02米，低刻(ke)(ke)度(du)(du)(du)距(ju)(ju)球(qiu)(qiu)(qiu)沖擊(ji)中(zhong)心0.61米，旋(xuan)轉抓(zhua)球(qiu)(qiu)(qiu)裝(zhuang)置吸住球(qiu)(qiu)(qiu)，移動(dong)抓(zhua)球(qiu)(qiu)(qiu)架，使鋼絲繩(sheng)拉直(zhi)，旋(xuan)轉抓(zhua)球(qiu)(qiu)(qiu)裝(zhuang)置放(fang)球(qiu)(qiu)(qiu)，沖擊(ji)墻體。

2、豎直自由落(luo)體沖擊方法。

將試樣(yang)保護層向(xiang)上平(ping)放于光滑的剛性(xing)底(di)板(ban)(ban)上，使試樣(yang)緊貼底(di)板(ban)(ban)。

試(shi)(shi)驗(yan)分為(wei)3J和10J兩級(ji)，每級(ji)試(shi)(shi)驗(yan)沖(chong)(chong)(chong)擊10個(ge)點(dian)(dian)。3J級(ji)沖(chong)(chong)(chong)擊試(shi)(shi)驗(yan)使用質量為(wei)500g的(de)鋼球，在距離(li)試(shi)(shi)樣(yang)(yang)上表(biao)面(mian)0.61m高度(du)自(zi)由降落沖(chong)(chong)(chong)擊試(shi)(shi)樣(yang)(yang)。10J級(ji)沖(chong)(chong)(chong)擊試(shi)(shi)驗(yan)使用質量為(wei)1000g的(de)鋼球，在距離(li)試(shi)(shi)樣(yang)(yang)上表(biao)面(mian)1.02m高度(du)自(zi)由降落沖(chong)(chong)(chong)擊試(shi)(shi)樣(yang)(yang)。沖(chong)(chong)(chong)擊點(dian)(dian)應(ying)離(li)開試(shi)(shi)樣(yang)(yang)邊緣至(zhi)少100mm，沖(chong)(chong)(chong)擊點(dian)(dian)間距不(bu)得(de)小于100mm。以沖(chong)(chong)(chong)擊點(dian)(dian)及其周圍開裂作為(wei)破(po)壞的(de)判定標準(zhun)。
