Anti-floating anchor structure of super long basement concrete floor
The invention discloses an anti-floating anchor structure of a super long basement concrete floor. The anti-floating anchor structure comprises a bedrock layer, a concrete floor and an anchor hole formed from the concrete floor downwards to the bedrock layer, an anchor (1) is arranged in the anchor hole, and an elastic material layer (2) is arranged on the outer side of the anchor between the topsurface of the concrete floor and the bedrock layer. According to the anti-floating anchor structure, the elastic material layer is arranged on the outer side of the anchor between the top surface ofthe concrete floor and the bedrock layer, the deformation characteristics of the elastic material layer are used to avoid the rigid contact between the anchor and the concrete floor, the constraint effect of the anchor is released, the mutual lateral stress between the concrete floor and the anchor in the consolidation and contraction deformation is reduced, namely, the restraint of the self consolidation and contraction deformation of the anchor on the concrete floor can be effectively reduced, and cracking of the concrete floor due to the limitation of the anchor is avoided.
本发明公开了一种超长地下室混凝土底板抗浮锚杆结构，它包括基岩层、混凝土底板及自混凝土底板向下开设到基岩层中的锚孔，在锚孔内设有锚杆（1），在混凝土底板顶面与基岩层之间的锚杆外侧设有弹性材料层（2）。本发明在混凝土底板顶面与基岩层之间的锚杆外侧设置弹性材料层，利用弹性材料层的变形特性，避免锚杆与混凝土底板刚性接触，释放锚杆的约束效应，减少混凝土底板在固结收缩变形中与锚杆之间产生的相互侧向应力，即能有效地减少锚杆对混凝土底板自固结收缩变形的约束，避免因锚杆限制而引起的混凝土底板开裂。
