RELATED ARTICLES外墻保溫抗沖擊試驗儀是外保(bao)溫系統抗沖擊試(shi)驗(yan)(yan)裝(zhuang)置(zhi)(zhi)(zhi)是我公司根據JGJ144-2004《外墻外保(bao)溫工(gong)程(cheng)技術規程(cheng)》A..5和B.3條研制(zhi)的(de)試(shi)驗(yan)(yan)裝(zhuang)置(zhi)(zhi)(zhi)。該裝(zhuang)置(zhi)(zhi)(zhi)可對外墻外保(bao)溫系統的(de)抗沖擊性能進行實驗(yan)(yan)室(shi)或(huo)現場(chang)試(shi)驗(yan)(yan),該裝(zhuang)置(zhi)(zhi)(zhi)結(jie)構(gou)簡(jian)單,使(shi)用方便,高度可調,采(cai)用磁力(li)抓球方式,操作使(shi)用方便,整機(ji)移動方便,適(shi)于在現場(chang)使(shi)用。
二、外墻保溫抗沖擊試驗儀技(ji)術參數
1、鋼球重量:0.5kg 1kg
2、沖擊高度調節范圍:0.6-1.3米
3、外形尺寸:350*350*1500mm
4、整機重量:12kg
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)。
