    配资盘施工中出現空鼓開裂的原因及解決方法

    2019-06-03 09:03:39 慧投金融配资 閱讀

    空鼓是施工中在進行原混凝土地面處理時常遇見的問題。空鼓現象我們無法用眼睛来判斷,也容易忽略,當把漆做上去之後從表面来看也很好,但由于是工廠車間,需長期经受叉車、推車、重型機械等的碾軋,時間長了,空鼓處就會破損、脫落,就會嚴重影響的使用壽命。

    Ground floor empty drum is a common problem encountered in the construction of Nanjing epoxy floor when the original concrete ground is treated. Empty drum phenomenon can not be judged by eyes, but it is easy to overlook. When epoxy floor paint is made, it is also very good from the surface. But because it is a factory workshop, it needs long-term rolling by forklift, cart, heavy machinery and so on. Over a long period of time, the empty drum will break down and fall off, which will seriously affect the service life of epoxy floor.

    空鼓開裂的原因

    Reasons for Cracking of Epoxy Floor Drum

    1、工期時間限制,在穿插施工時混凝土強度未达标準的情況下,安裝及後續工程急于趕工期,同時施工單位對地面養護不夠等原因,造成混凝土表面強度過低。

    1. Time limit of construction period. When the strength of concrete is not up to the standard during the construction, the installation and follow-up works are in a hurry to catch up with the construction period. At the same time, the construction unit does not maintain the ground enough, which causes the surface strength of concrete to be too low.

    2、混凝土施工前,基層水泥套漿不均勻,用撒水泥的方法圖帶水泥均勻套漿,影響面層和基層的粘接力。

    2. Before concrete construction, the cement slurry of base course is not uniform. The method of spraying cement is used to map the uniform slurry of cement, which affects the adhesion between surface layer and base course.

    3、施工前準備工作,未将混凝土繼承中的水泥漿和裝修階段天棚掉落的石膏清理幹淨,造成與面層混凝土粘結接力下降,出現表面施工後空鼓及開裂現象;

    3. Preparations before construction did not clean up the cement slurry inherited from the concrete and gypsum dropped from the ceiling during the repair stage, which resulted in the decrease of the bonding force with the surface concrete and the appearance of hollowing and cracking after surface construction.

    4、施工時,混凝土施工時为将雙向配筋放在細石混凝土面層的上不,導致面層抵抗力降低,混凝土因收縮長生面層開裂現象;

    4. During the construction, in order to put the two-way reinforcement on the surface of fine stone concrete, the resistance of the surface layer is reduced, and the cracking of the surface layer is caused by the shrinkage of the concrete.

    5、人工誤差,人工攪拌混凝土,混凝土配計量存在一定誤差,局部恒凝土的強度未达到标準要求,因強度不夠,汽車在車庫所産生的停車及轉彎刹車時産生較大摩擦,造成表面起砂,在車道轉彎處比直線車道大,才成車道破損和其他較为嚴重的問題。

    5. Artificial errors, artificial mixing concrete and concrete mixing measurement have certain errors. The strength of local constant-setting soil does not meet the standard requirements. Because of the insufficient strength, the parking and turning braking of the car in the garage produce greater friction, resulting in sand on the surface, which is larger at the turning of the lane than that of the straight lane. Only then can the lane be damaged and other serious floor problems occur.

    空鼓開裂的解決方法

    Solution to the Cracking of Epoxy Floor Drum

    1、将空鼓位置全部切除,地面清理幹淨。

    1. Remove all empty drum positions and clean up the ground.

    2、将地面清理幹淨,浮灰、碎砂,漿膜等其它污物。

    2. Clean up the ground, float ash, crushed sand, slurry and other dirt.

    3、将澆水潤濕。面層施工前1-2天,應對基層認真進行澆水濕潤,使基層具有清潔、濕潤、粗糙的表面。

    3. Wet the floor with water. 1-2 days before the construction of the surface layer, the grass-roots should be watered and wetted carefully, so that the grass-roots has a clean, wet and rough surface.

    4、配资盘施工。施工時注意一下幾點:

    4. Floor construction. A few points should be paid attention to during construction:

    (1)控制好水泥砂漿水灰比

    (1) Controlling the Water-cement Ratio of Cement Mortar

    (2)控制好施工時間,防止壓光過早或者過遲

    (2) Controlling construction time to prevent premature or late calendering

    (3)注意地面平整度,以及室内淨高的控制

    (3) Pay attention to the control of ground evenness and indoor net height

    5、施工完成24小時候澆水養護。

    5. Watering maintenance 24 hours after completion of construction.
