Description
Technical field
The present invention relates to a kind of building construction technologies, more specifically, it relates to a kind of prevention terrace differential settlement knot
Structure and construction method.
Background technology
Currently, usually needing large-area fill-back earth when the relatively low place of topography carries out engineering construction, pile foundation is built
For, the agent structures such as column, wall lower part is often arranged pile foundation and settles smaller, but indoor terrace is generally using recent fill
The rigid terrace of base, when banketing thicker, sedimentation it is larger, close to column, wall position terrace by pile foundation influenced sedimentation it is smaller, because
This, indoor terrace be usually present it is apparent it is uneven sink, to influence the normal use of building.
Chinese patent publication No. CN103806435A discloses a kind of terrace settlement treatment method and floor structure, existing
One group of vertical reinforcing bar is uniformly squeezed into some backfill layers, vertical reinforcing bar bottom is contacted with the bearing layer of underground,
Bar-mat reinforcement in the top and reinforced concrete floor of vertical reinforcing bar is welded into a whole, will by one group of vertical reinforcing bar
The weight transmitting of terrace surface is to bearing layer, to prevent settling.Common scaffolding steel pipe can be used in the steel pipe that the present invention uses,
It is of low cost, meet design requirement as supporting course support；Bar-mat reinforcement also can be connected to be formed with regular reinforcement, easily be bought；Weight
It is new to fill out the easily constructions such as backfill, graded sand and stone laying, concrete cast.The present invention is suitable for terrace during use or small
There is the processing after sedimentation in type Equipment Foundations, but complicated, and construction is inconvenient.
Invention content
The present invention overcomes indoor terrace sedimentation unevenness, influence the deficiency for building normal use, provide a kind of pre- defense sector
Level ground differential settlement structure and construction method, it assures that the uniform settlement of indoor terrace, ensures the normal use of building, simultaneously
Convenient for intuitively finding out the settling height of terrace.
In order to solve the above-mentioned technical problem, the present invention uses following technical scheme：A kind of prevention terrace differential settlement knot
