环氧地坪施工對於膨脹縫(伸縮縫)的處理

在环氧地坪工程中，大部分都使用混凝土作為基礎，而混凝土基礎存在這一個人力無法改變的因素，就是混凝土會根據环境溫度進行熱脹冷縮，所以混凝土澆築後必須切割有伸縮縫作為混凝土自身熱漲冷縮的緩沖空間，那麼對於膨脹縫的處理，總結給出瞭以下幾點建議：
In epoxy floor engineering, most of the use of concrete as a foundation, and concrete foundation there is a human force can not change the factor, that is, the concrete will be based on the ambient temperature for thermal expansion and cold contraction, so the concrete after pouring must be cut expansion joints as the concrete's own thermal expansion and cold contraction buffer space, so on. In the treatment of expansion joints, the following suggestions are summarized.

一、暗縫的處理
First, the treatment of dark joints.
1.應該及時清除膨脹縫隙裡的沉積物;
1., we should remove the deposits in the expansion slot in time.
2.在縫隙中填入彈性墊襯物，墊襯物到地面的高度通常為縫寬的一半;
2. fill the gap with elastic pad. The height of the mat to the ground is usually half the width of the seam.
3.塗上底漆後再用环氧砂漿填平縫隙;
3. apply primer and then use epoxy mortar to fill the gap.
4.在膨脹縫上可再鋪上玻璃纖維加強網以加強修補材料附著強度防止開裂;
4. on the expansion joint, glass fiber reinforced mesh can be laid to reinforce the adhesion strength of the repair material and p环氧地坪revent cracking.
5.在加強網上塗上环氧漆，完成膨脹縫的處理。
5., we should strengthen epoxy coating on the web and complete the treatment of expansion joints.
二、明縫的處理
Two. Treatment of open seam
1.在塗裝完成的表面沿膨脹縫切割
1. cutting along the expansion joint on the finished surface.
2.在縫的兩邊貼上分色紙
2. affix colored paper on both sides of the seam.
3.填入填入彈性墊襯物，墊襯物到地面的高度通常為縫寬的一半
3. fill in the elastic pad. The height of the mat to the ground is usually half the width of the seam.
4.在縫內打入填縫膠並壓實
4. sealant and compacting in the seam.
5.立刻撕去分色紙，完成明縫處理。
5. tear off the coloured paper immediately and finish the open seam treatment.
三、墻角的處理
Three, the processing of the corner.
墻面和地面相交的地方需要處理成圓弧形，以防止塗裝時滲漏到拉縫，並且更利於地面以後的使用和清潔維護;
The area where the wall and the ground intersect needs to be treated as a circular arc to prevent leakage to the joints when painting, and is more conducive to the use of the ground after cleaning and maintenance;
1.打磨清潔墻角，保證幹燥、無油污、無松脫物。
1. polish and clean the corners of the wall to ensure dry, oil free and no loose objects.
2.用封固底漆封固。
2. seal with primer.
3.用聚合物水泥或环氧砂漿抹成圓弧形。
3. use polymer cement or epoxy彩色沥清地坪 mortar to form circular arc.
