Technical Field
The utility model relates to a post-cast belted steel silk screen built-up plate, in particular to post-cast strip side is solid, and interior wire net combination formwork system props up.
Background
In order to prevent harmful cracks possibly generated by uneven temperature and shrinkage of a cast-in-place reinforced concrete structure in the construction process, temporary construction joints are reserved at corresponding positions of a foundation slab, a wall and a beam during construction in the former period according to design or construction specification requirements, the structure is temporarily divided into a plurality of parts by the temporary construction joints, the parts are shrunk through the inside of the components, concrete is poured and tamped at each temporary construction joint during construction in the later period, and the structures are connected into a whole. The post-cast strip is concrete poured and pounded at the temporary construction joint. High-rise and super high-rise buildings are more and more in modern building construction, and foundation parts of the buildings are deeper and deeper. The post-cast strip of foundation slab and wall body adopts traditional post-cast strip to reserve the mode of establishing mostly, and the post-cast strip must pour the post-cast strip concrete after the major structure construction is accomplished, therefore must continuously carry out precipitation in order to guarantee that the groundwater level is below the foundation slab. Long-term precipitation not only increases construction cost, but also wastes underground water resources. In addition, for deep underground foundation engineering, if earth is not quickly backfilled after the foundation is finished, potential hazards are brought to the safety of the foundation engineering, and the construction of other procedures can be influenced without backfilling the foundation earth, so that the construction period of the engineering is influenced.
In recent years, the problems are solved by adopting an advanced water-stop post-cast strip construction technology, wherein the advanced water-stop strip is formed by adding a telescopic concrete bottom plate or a guide wall at a temporary construction joint during early construction, and arranging a rubber water-stop strip at the expansion joint. Such a water stop used at the post-cast position and cast prior to the post-cast is called a leading water stop. The advanced water stop belts are all related to the retention of an expansion joint in the middle of the advanced water stop belt, an extruded polystyrene board or a wood fiber asphalt board is filled in the expansion joint, and a rubber water stop belt is arranged in the middle of the expansion joint. However, the structure has certain defects, and the rubber waterstop is easy to deviate and crack in the concrete pouring construction due to poor fixation; the extruded polystyrene board or the wood fiber asphalt board has insufficient strength to cause deformation in construction. The defects can cause the leading water stop to leak water, bring adverse effects to the water prevention of the post-pouring strip and seriously bring adverse effects to the building safety.
