Construction method of VNA directional passing super-flat floor
The invention relates to the field of floor construction, in particular to a construction method of a VNA directional passing super-flat floor. Before concrete pouring, steel bar frames and dowel bars are pre-arranged at positions corresponding to bin dividing seams and kerf shrinkage seams, telescopic joints of the dowel bars are fixed to the positions corresponding to the seams, and when the surface of the floor is subjected to a large load, concrete blocks on the two sides of the seams are moved, and the dowel bars can stretch out and draw back, so that stress transmission between the adjacent concrete blocks on the two sides of the seams is increased, and therefore uneven settlement of a concrete pavement caused by large load of local stress of the concrete pavement is prevented; and the adjacent concrete blocks are jointly stressed through stress transmission, so that buckling deformation of the bin dividing seams and the shrinkage seams under the long-term load effect is reduced, and the flatness of the super-flat floor is guaranteed.
本申请涉及地坪施工的领域，尤其是涉及一种VNA定向通行超平地坪的施工方法，混凝土浇筑前，在分仓缝和切缝缩缝对应的位置处预置钢筋架和传力杆，传力杆的伸缩节点处对于缝的位置，在地坪表面受到较大荷载时，导致缝两侧的混凝土块发生移位，此时传力杆可以进行伸缩，增加缝两侧相邻的混凝土块之间的应力传递，以防止混凝土路面局部受力较大荷载造成混凝土路面不均匀沉降，传递应力使相邻的混凝土块共同受力，从而减少分仓缝和缩缝在长期荷载作用下出现翘曲变形的情况，保证超平地坪的平整度。
