Description
Technical field
The present invention relates to a kind of advanced construction methods of cover board and post-cast strip for the construction of top plate pouring after settlement.
Background technology
The setting of pouring after settlement is in order to prevent between the main building of skyscraper and group room or basement because of the difference of sedimentation
Different difference causes to cause structural cracks.By the requirement of code for structural design and construction specification, the concrete of pouring after settlement
Cast, it is necessary to wait for main building（It is high-rise）Structure all constructed（Top out）It can construct later.But it is applied in building
In work, especially in the engineering construction of last decade, most of high building project need to be inserted into interior decoration and tube net outside in advance
And municipal administration, road, afforestation project etc., but because scene can not be closed in time, basement finishing and electromechanical installation can be poured due to after
Band percolating water affects, and exterior components can not almost construct.
The prior art, which solves the above problems, utilizes following construction method：In structure construction, alter-pouring strips mould plate is designed to
Independent system is separated with other templates, convenient for the form removable outside post-cast strip region.The construction of first floor floor construction finishes, the buildings Ji
Using armored concrete prefabricated cover board covering on plate, and with overall structure synchronous construction waterproof layer and backfill, when construction according to
4m spacing, which is stayed, sets 3m high, diameterPouring hole of 300 concrete reinforced pipes as concrete.Pass through again after structure sediment stabilization
Concrete pouring hole pours self-compaction expansive concrete into post-cast strip.
But there is also following disadvantages for the above-mentioned prior art：First, it can not ensure the close of the prefabricated cover board edge joint position in post-cast strip
Closing property.Secondly, geometric error caused by the differential settlement of post-cast strip both sides can not be become by the prefabricated cover board of armored concrete
Shape is offset, and is existed and is finished the hidden danger that waterproof roll damages to having constructed.In addition, to being poured after L-shaped, cross or fold-line-shaped
Band does not solve the cover board piece of turning point.Finally, must reserve concrete casting hole on top plate coiled material, top plate waterproof coiled material without
Method seal closure.

The present invention is used for the cover board of top plate pouring after settlement construction, further, the cover board body, first as described above
Connector and the second connector are integrally formed, and whole is in convex shape.
The present invention is used for the cover board of top plate pouring after settlement construction as described above, further, on first connecting plate
At least two bolt connecting holes are offered, bolt connecting hole is of a straight line type arrangement, shaped form arrangement or irregular arrangement.
The present invention is used for the cover board of top plate pouring after settlement construction as described above, and further, two cover boards are attached
When, the four side of the cover board body of first cover board is fixed to and is formed by plate in the channel steel of second cover board and cover board body
Mother-son mouth position.
The cover board that the present invention is used for the construction of top plate pouring after settlement as described above further includes further sealing compound, described
Sealing compound is filled in the gap position that the cover board body of two adjacent cover boards is formed.
In order to realize above-mentioned second purpose, the present invention provides a kind of advanced construction method in basement roof post-cast strip, including
Following steps：
Step 1, alter-pouring strips mould plate is installed below structure floor, binds post-cast strip steel bar；
Step 2, concrete pumping hose is installed, between concrete pumping hose is placed in top plate double steel bar mesh sheet,
Double steel bar mesh sheet muscle smears lubricant, and concrete pumping hose carries out prestretching after installing, it is ensured that concrete pumping hose
It can smoothly be pulled；
Step 3, cover board is installed, is secured the lid to above structure floor；The cover board is any one of claim 1-4 institutes
The cover board for the construction of top plate pouring after settlement stated；
Step 4, on the inner corner trim position casting concrete inclined-plane that the cover board connecting component of cover board is formed；
Step 5, the laying water-proof coiled material above structure floor and cover board backfills element soil on waterproof roll；
Step 6, the post-cast strip position installation concrete lift-up between structure floor pours device；
Step 7, it after agent structure binds or in the case of meeting design requirement, carries out concrete lift-up and pours, in structure
Post-cast strip is formed between floor.
The present invention advanced construction method in basement roof post-cast strip as described above, it is preferable that in step 3, cover board is logical
