耐磨环氧地坪施工後切割伸縮縫的註意事項
核心提示:混凝土环氧地坪工程施工完畢後都要做最後彩色沥清地坪一步的處理,即环氧地坪伸縮縫的切割及處理,耐磨地坪也不例外。耐磨环氧地坪施工後切割伸縮縫的註意事項:1、準確掌握切割伸縮縫的時機是關鍵,切早瞭容易崩邊、切完瞭起不到作用。耐磨地坪的伸縮縫切割的最佳時間即為施工完工後的第二天。除合理掌握時間外,切割伸縮縫的順直取決於彈線和切割兩方面,必要情況下可以借助紅外線發射器彈線,挑選技術熟練的工人切割,以此保證切割出來的伸縮縫是順直的。切割伸縮縫的寬度一般為3-5mm,深度一般為水泥混凝土厚度的1/3-1/2,切割伸縮縫後分隔出的水泥混凝土區域塊的長、寬尺寸以6-8m為宜,可以按柱距或設計圖紙要求為準。
Core Tip: After the construction of the concrete floor project, the last step should be done, that is, the cutting and treatment of floor expansion joints, wear-resistant floor is no exception. Precautions for cutting expansion joints after abrasion resistant epoxy floor construction:
1. Accurate grasp of the timing of cutting expansion seam is the key, cutting early easy to collapse edge, cutting finished can not play a role. The best time for cutting the expansion joint of the wearable floor is the second day after the completion of construction. In addition to a reasonable grasp of time, cutting expansion seam straightness depends on both the line and cutting, if necessary, with the help of infrared projectile line, select skilled workers to cut, in order to ensure that the cut out expansion seam is straightforward. The width of the cut expansion joint is generally 3-5mm, and the depth is generally 1/3-1/2 of the cement concrete thickness. The length and width of the cut expansion joint are 6-8m, and the column spacing or the design drawing can be used as the standard.
2、透水地坪切縫後,應立即將在伸縮縫兩側產生的水泥灰漿清除,避免幹燥後難於清理。
2. After slitting, the cement mortar produced on both sides of the expansion joint should be removed immediately to avoid difficult cleaning after drying.
3、填縫前需將縫內小石子、渣土等用鉤子鉤清,再用工業吸塵器清除縫內粉塵,必要時可用水沖洗,待幹燥後再根據設計要求填縫。
3. Before filling the seam, the pebbles and slag in the seam should be cleared by hook, and then the dust in the seam should be removed by industrial vacuum cleaner. When necessary, the seam should be washed with water, and then the seam should be filled according to the design requirements after drying.
4、伸縮縫底部先填塞(6個單位直徑)的海綿膠條,頂部用聚氨酯填縫膠專用打膠槍均勻填充。填充時註意填充均勻、飽滿,不得有空洞、斷頭等現象,邊填充邊修飾,使表面光滑、順直、美觀。同時,避免對伸縮縫邊緣及以外的區域造成污染,一旦污染應及時清除,必要時可借助對耐磨地坪無腐蝕的化學溶劑。
4. The bottom of the expansion joint is filled with sponge tape (6 unit diameters), and the top is filled with polyurethane sealant gun. When filling, pay attention to filling uniform, full, no cavities, broken ends and other phenomena, while filling edge modification, so that the surface smooth, straight, beautiful. At the same time, avoid contamination on the edge of expansion joint and other areas, once the contamination should be removed in time, if necessary, with the help of non-corrosive chemical solvents on the wear-resistant floor.
