Technical field
The present invention relates to a kind of anti-floating construction method of NZ internal mold, particularly relate to the built-in hollow tube mode anti-floating construction method of a kind of cast-in-situ concrete.
Background technology
For a long time, cast-in-place concrete building roof uses the girt strip plate or with the solid floor of cap, thereby the former uses function because the existence of beam has reduced the impact of building clear height, and the furred ceiling expense is high, and pipeline is installed inconvenience, and soundproof effect is poor, long construction period; The latter is from great, unsuitable large span, large bay, cap inconvenience finishing.Traditional cast-in-place concrete building roof can not meet modern architecture large space, large bay, large load, use the demand of flexible function.NZ internal mold (polyethylene foam material that is wrapped up and strengthened by the B0B adhesive tape) cast-in-situ hollow building roof technology is exactly a kind of new architecture of for overcoming these drawbacks, arising at the historic moment.It obtains liking of more and more owners in conjunction with numerous advantages, particularly along with building, uses the variation of function, and this form of structure has wide development space.But how to guarantee that it is the general bias construction difficult problem that runs in construction that the NZ internal mold does not produce because of concrete in the cast-in-place concrete construction process buoyancy floats.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of NZ of preventing internal mold does not make built-in hollow tube mode that the NZ internal mold anti-floating construction method of floating occur because of the buoyancy of mobile concrete generation in the cast-in-place concrete hollow building roof work progress.
For solving the problems of the technologies described above, NZ internal mold anti-floating construction method provided by the invention, will be pressed in muscle and support for shuttering at the bottom of muscle at the bottom of Anti-floating reinforcing steel bar on the NZ internal mold and plate, plate by iron wire and be linked to be integral body, allow the very light NZ internal mold of density be in annular pressured state.
Concreting time-division two-step pouring, build for the first time to thickness of slab 1/2 place, treats before concrete initial set to build the concrete on top 1/2 again.
Adopt the NZ internal mold anti-floating construction method of technique scheme, be linked to be integral body by being pressed in muscle and support for shuttering at the bottom of muscle at the bottom of Anti-floating reinforcing steel bar on the NZ internal mold and plate, plate, allow the very light NZ internal mold of density be in annular pressured state, thereby avoided solving the NZ internal mold anti-floating problem of cast-in-place concrete floor because concrete allows it change its Ying Chu position to the buoyancy of its generation.Cause internal mold to destroy for avoiding concreting internally to be molded as excessive buoyancy, adopt the way of placement layer by layer in concreting process, namely first floor concrete casting to 1/2 thickness of slab, treat after vibration compacting to build layer concrete before concrete initial set again.This way has guaranteed that the concreting of internal mold bottom space is closely knit, avoided in the primary concreting process being difficult for finding vibrating head under shake and a little cause destruction to the NZ internal mold.Can effectively solve the NZ internal mold by the method and the problem of floating occur in concreting process, thereby guarantee floorslab concrete structure construction quality.
In sum, the present invention is that a kind of NZ of preventing internal mold does not produce because of the concrete that flows in the cast-in-place concrete hollow building roof work progress buoyancy makes built-in hollow tube mode that the NZ internal mold anti-floating construction method of floating occur.
Description of drawings
Fig. 1 is the measure of anti float schematic diagram.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
NZ internal mold anti-floating construction method provided by the invention, step is as follows:
(1), at the bottom of diving board on the slab form 1 that has installed the muscle line of ink marker, outside 5 positions, the crosspoint peripheries 15mm of muscle at the bottom of the plate that the pipe die installation site is arranged, symmetrical electricity consumption is drilled in jewel hole on template 1, aperture 5-8mm.
(2), muscle 5 at the bottom of the plate of colligation hollow building cover, and at the bottom of plate the reinforcing bar crosspoint of muscle 5 at interval of 800 * 800(㎜) pad one plate topping cushion block 4.
(3), with the eyelet of No. 12 iron wires 2 by having bored, muscle at the bottom of plate 5 is become an integral body with the horizontal steel tube colligation of full hall support for shuttering 3.
(4), by designing requirement, install NZ internal mold 9, then press 2 Anti-floating reinforcing steel bars 8 with plate gluten 6 same specifications on every row NZ internal mold 9, then No. 16 iron wire 7 colligations of muscle 5 use at the bottom of this Anti-floating reinforcing steel bar 8 and plate are firm.Thereby the Anti-floating reinforcing steel bar 8 that will be pressed on NZ internal mold 9 is linked to be an integral body with muscle 5 at the bottom of plate and full hall scaffold 3.Connect into whole drawing and see Fig. 1.
(5), plate gluten colligation
After the complete plate gluten 6 of colligation, can make muscle 5 at the bottom of plate, Anti-floating reinforcing steel bar 8, plate gluten 6 form the space structures that can be subjected to the temporary construction load, can be used as the temporary construction passage after spreading the bamboo frame plate, to facilitate the workman to operate and to prevent from trampling on internal mold.
(6), concreting
During construction, first build post position concrete, after the vertical structure concrete vibrating is closely knit, then casting beams board position concrete.For NZ internal mold 9 cast-in-situ hollow floor plates, if once concreting is pushed up to plate, the rib of slab position is covered by concrete, not only be inconvenient to vibrate but also make 9 times air of NZ internal mold be difficult for discharging, be easy to cause 9 times concrete vibrating leakiness of NZ internal mold, occur that honeycomb, pitted skin even leak muscle and hole.So for preventing the concrete vibrating leakiness of NZ internal mold 9 and base plate, the concrete of every thickness of slab has been built in two steps.
1), whole NZ internal mold 9 concrete ribs of every block of plate are watered to 1/2 height, should use 30mm diameter internal vibration rod 10 parallel inner membrance directions careful vibrated concrete successively, vibrating spear inserts spacing 300mm.All flanks spacing in accordance with regulations vibrate, and must not leak and shake, and make 9 times air exhaustings of NZ internal mold except clean, and 9 times concrete vibratings of NZ internal mold are closely knit.
2), after all concrete ribs of this piece plate are built vibration compacting, before being controlled at concrete initial set, the concreting of residue thickness of slab to design elevation, and is carried out secondary to concrete rib targetedly and is shaken again.
3) use the vertical direction vibro-rammer surface concrete of concrete flat slab vibrator along fix N Z internal mold 9, then just flat with floating rule, then with cylinder, roll, after initial set with wood wipe one's face compacting, pressing, receipts light.
(7), form removable
Protect the form removal test block according to the concrete real curing of keeping somewhere, remove floor base plate template 1 after concrete pressure testing report reaches the form removable condition, No. 12 iron wires 2 that expose at concrete floor adopt abrasive machine worn.
