The making of described bottom plate rear pouring tape resistance to compression plate is meant that the thickness of making the resistance to compression plate is 1/2-1/3 of ater-casting width, and be no more than base plate thickness, the width of resistance to compression plate is 2m, and make 45 degree hypotenuses, and configuration is two-way concrete slab up and down, and reinforcing bar inserts in the basement bottom board with 45 degree, wherein resistance to compression plate middle part is provided with rubber fastening band, the rubber fastening band upper and lower surface is filled up a kind of in pitch flax silk or the cystosepiment, is not destroyed with the protection rubber fastening band, plays the permanent water-resistant effect; The resistance to compression plate re-lays the thick SBS modified asphalt waterproof coiled material of one deck 4mm at its external surface after watering and smashing maintenance; The two-way concrete slab up and down that resists then on the pressing plate carries out colligation.
Described rubber fastening band adopts the rubber fastening band of Ω type, and will add the pitch flax silk in the top and bottom of rubber fastening band.
The making of described bottom plate rear pouring tape is meant that employing builds than the expansive concrete that former concrete grade improves one-level, wherein mixes the UEA-H concrete expansion waterproof agent of 10% place of cement; The grade beam main reinforcement at position, ater-casting does not block hoop and encrypts, the base plate reinforcing bar does not also block and sets up the additional bar that is no less than former arrangement of reinforcement 15% and stretches into each 1000mm of both sides, ater-casting, the retained flat in ater-casting, the thick steel plate for sealing water waterproof of 3mm is adopted at the base plate middle part, and the both sides, ater-casting adopt the dense mesh that easily closes up to isolate the interception concrete.
The making of described side wall ater-casting is identical with the way of bottom plate rear pouring tape; but be provided with in the outside 300mm thick water the steel concrete protection side plate of smashing simultaneously with other position side walls; the same side wall of arrangement of reinforcement; width is 2m; with side wall with high, so just formed tight waterproof system, the ater-casting do not water smash before; can carry out the side wall waterproofing work, return soil.
Beneficial effect of the present invention is: the present invention adopts to stay and establishes the ater-casting and solve the problem that the long and plane change of shape in house produces distress in concrete, and basement is not seeped water, and guarantees workmanship, satisfies daily instructions for use.
The specific embodiment
Embodiment 1
A kind of basement post-pouring zone construction process of present embodiment indication comprises the making of bottom plate rear pouring tape resistance to compression plate, the making of bottom plate rear pouring tape, the making of side wall ater-casting.The making of bottom plate rear pouring tape resistance to compression plate is meant that the thickness of making the resistance to compression plate is 1/2-1/3 of ater-casting width, and be no more than base plate thickness, the width of resistance to compression plate is 2m, and makes 45 degree hypotenuses, configuration is two-way concrete slab up and down, and rubber fastening band adopts the rubber fastening band of Ω type; The rubber fastening band non-deformability of Ω type is strong, can not adopt yi word pattern waterstop or reclaimed rubber waterstop, and will add the pitch flax silk thereon, plays the effect of permanent waterproof.Reinforcing bar inserts in the basement bottom boards with 45 degree, and wherein resistance to compression plate middle part is provided with rubber fastening band, and the rubber fastening band upper and lower surface is filled up a kind of in pitch flax silk or the cystosepiment, is not destroyed with the protection rubber fastening band, plays the permanent water-resistant effect; The resistance to compression plate re-lays the thick SBS modified asphalt waterproof coiled material of one deck 4mm at its external surface after watering and smashing maintenance; The two-way concrete slab up and down that resists then on the pressing plate carries out colligation.The bottom plate rear pouring tape resistance to compression plate that present embodiment is made has the impermeable ability in crack that do not produce.
The making of bottom plate rear pouring tape is meant that employing builds than the expansive concrete that former concrete grade improves one-level, wherein mixes the UEA-H concrete expansion waterproof agent of 10% place of cement; Before concreting, remove the foreign material in the ater-casting, the corrosion reinforcing bar should remove and embroider, and the concrete loose stone that both sides are watered earlier cuts, and cleans up, and can increase the adhesion stress between the new-old concrete like this.The grade beam main reinforcement at position, ater-casting does not block hoop and encrypts, the base plate reinforcing bar does not also block and sets up the additional bar that is no less than former arrangement of reinforcement 15% and stretches into each 1000mm of both sides, ater-casting, the retained flat in ater-casting, the thick steel plate for sealing water waterproof of 3mm is adopted at the base plate middle part, and the both sides, ater-casting adopt the dense mesh that easily closes up to isolate the interception concrete.Will in time clear up if having slurries and concrete to flow into the ater-casting, best two sections alter-pouring strips mould plates will stay 500mm long-term job plate, are beneficial to concrete and flow out.Construction period, the both sides, ater-casting should properly be supported, to guarantee member and structure thereof supporting capacity and the stability in the construction stage.Base plate is built two skin bricks along place, both sides, ater-casting, covers with nine clamping plate, crashes in the ater-casting to prevent other objects, keeps the cleaning of ater-casting, prevents other objects, is brought into the ater-casting as wood chip by water, has water in time to discharge as the ater-casting, to prevent corrosion of steel bar.The bottom plate rear pouring tape that present embodiment is made has been strengthened the function of waterproof.
The making of side wall ater-casting is identical with the way of bottom plate rear pouring tape; but be provided with in the outside 300mm thick water the steel concrete protection side plate of smashing simultaneously with other position side walls; the same side wall of arrangement of reinforcement; width is 2m; with side wall with high, so just formed tight waterproof system, the ater-casting do not water smash before; can carry out the side wall waterproofing work, return soil.
The ater-casting retention time is no less than two months, or waters behind the agent structure knot top again and smash, and the quality of strict control concrete raw material, and the aggregate mud content is below 1%, and cement is selected the lower Portland cement of the heat of hydration for use, should keep somewhere test block in accordance with regulations when building.Build 2 skin brick water storing conservations in both sides after the concreting of ater-casting, side wall will often manually water, and curing time was 2 weeks.
