Technical Field
The application relates to the field of house construction, in particular to a construction method of a basement structure.
Background
The existing basement is that the height of the ground of a room lower than the ground level of the outdoor is more than one half of the net height of the room, and a multi-storey and high-rise building needs a deeper foundation.
The basement in the building construction adopts the construction of jumping the storehouse, and the roof beam cantilever end that construct earlier are overlength, need carry out long-time back-jacking. The Chinese checkers method is characterized by that it fully utilizes the "resisting and releasing" characteristic principle of that the concrete is not stable in performance and can easily release internal stress before it is completely solidified in 5-10 days, and is characterized by that the building foundation or large-area concrete plane mechanism is divided into several zones, and constructed according to the principles of "block-dividing planning, block-separating construction, layer-pouring and integral forming", and its mode is identical to that of Chinese checkers, i.e. one section is poured at intervals. The interval time of two adjacent sections is not less than 7 days, so that the violent temperature difference and drying effect of the initial concrete construction part are avoided, and a post-cast strip is not required to be left.
With respect to the related art among the above, the inventors consider that the following drawbacks exist: in the prior art, the temporary column or the back jacking frame body is additionally arranged below the top plate for supporting, so that the construction cost is high, the temporary column or the outward-conveying frame body material needs to be chiseled after the subsequent top plate is connected, and the labor cost and the construction period are increased.
