腳手架變形的原因及改進廣西鋼管租賃

2021-10-20 14:54:07

首先,腳手架扎根的懸臂鋼梁撓度變形超過規定值,需要加強懸臂鋼梁后面的錨固點,用鋼支撐和U型支架擰緊鋼梁,以抵抗屋面。預埋鋼圈與鋼梁之間有一個開放空間,必須用馬楔固定。逐一檢查吊在鋼梁外端的鋼絲繩,并全部緊固,確保受力均勻。柳州鋼管租賃

其次,如果腳手架的卸拉系統部分損壞,應立即按照原方案制定的卸拉方法進行恢復,并對變形部位和桿件進行矯正。例如,為矯正腳手架向外變形,每個隔間設置5t鏈條,剛性拉點隨結構收緊而放松。同時在各點向內拉緊鏈條,直至變形糾正,完成剛拉連接,在各卸載點拉緊鋼絲繩,使受力均勻,鏈條展開。柳州鋼管

第三,梯形腳手架因基礎沉降而部分變形。在雙排架的橫截面上,設置八字形或剪刀形,每隔一排立柱設置一組,直到變形區排出。八字跨度或剪刀支撐腳必須位于堅實可靠的基礎上。

當腳手架斷裂變形時,說明它有一些危險因素。此時,我們需要保護和維護它,而不是視而不見,把它變成一場災難。所以,腳手架的變形對我們來說是一個暗示,我們需要理解這個暗示是什么意思。廣西鋼管租賃
