Description
Technical field
The present invention relates to technical field of buildings, and in particular to a kind of post-cast strip anti-cracking waterproof structure construction technique.
Background technology
Often pour slightly expanded concrete in post empiricism in post-cast strip at home, slightly expanded concrete can be poured with after
Concrete with both sides is linked to be an entirety and plays good waterproof effect.
But for many years show that post-cast strip position is still the multiple position for occurring percolating water phenomenon through engineering practice, it is main
The reason is that the effects that uneven settlement of foundation and sole plate anti-floating influences, concrete generation sedimentation in post-cast strip both sides is excessive to be caused
Cracking is to generate leakage phenomenon.
There are gaps between steel wire and base in traditional handicraft simultaneously, and concrete vibrating is in the process often from gap
It flows into post-cast strip, post-cast strip inner concrete is caused to deposit, not only need to increase recruitment cleaning post-cast strip inner concrete but also shadow
Ring post empiricism quality.
Based on problem above, the present invention is desirable to provide a kind of post-cast strip anti-cracking waterproof structure construction technique, improves post-cast strip
Construction quality.
Invention content
The present invention provides a kind of post-cast strip anti-cracking waterproof structure construction technique, it is therefore intended that solves to carry in above-mentioned background technology
There are gaps, concrete vibrating often to be poured after being flowed into gap in the process between steel wire and base in the traditional handicraft gone out
Band in, cause post-cast strip inner concrete deposit the problem of.
To achieve the above object, the present invention provides a kind of post-cast strip anti-cracking waterproof structure construction technique, Specific construction step
To be as follows,
Step 1, material prepare：
Prepare construct common water-proof concrete, microdilatancy water-proof concrete, steel plate for sealing water, structure reinforcing bars, microlith waterproof
Concrete, B reinforcing bars, close hole wire netting and flitch etc.；
Step 2, microlith water-proof concrete item pour：
After base cleaning is clean, mold is made with flitch in post-cast strip both sides, pours wide 3cm, is highly protected with lower layer's reinforcing bar
Covering thickness, microlith water-proof concrete item of the length along the elongated setting in post-cast strip；
Step 3, post-cast strip steel bar binding, close hole steel wire, hang mould at steel plate for sealing water installation：
Microlith water-proof concrete item starts to bind the structure reinforcing bars 6 of board bottom, structure reinforcing bars after maintenance reaches some strength
After the completion of binding, close hole steel wire net rack is made using B reinforcing bars and close hole wire netting, the close hole steel wire net rack of lower layer is installed, then will
Steel plate for sealing water is fixed on the close hole steel wire net rack of lower layer, then installs the close hole steel wire net rack on upper layer, the structural steel on binding plate top
Plate top is finally put into above structure reinforcing bars and hangs mould with flitch by muscle；
Step 4, post-cast strip both sides water-proof concrete pour：
Hang mould complete it is qualified by inspection after, common water-proof concrete is cast in post-cast strip both sides, it is desirable that concrete vibrating
It is closely knit, cover water seasoning after the completion of concreting；
Step 5, microdilatancy water-proof concrete pours in post-cast strip：
It waits for that common water-proof concrete maintenance is completed and reaches the design requirement time limit, starts to pour post-cast strip inner concrete, pour
Rubbish in the close hole steel wire net rack and post-cast strip of post-cast strip both sides should be first cleared up before building, and is cut loose concrete and rushed with clear water
Wash clean adjusts structure reinforcing bars.It is anti-with the microdilatancy of a grade higher than common water-proof concrete intensity after the completion of preparation
Water coagulation soil is poured, it is desirable that vibration compacting, water seasoning after the completion of microdilatancy water-proof concrete pours.
Preferably, in step 3, the close hole steel wire net rack surrounding is the B8 reinforcing bars of welding, midfeather welding support
B8 reinforcing bars constitute framework of steel reinforcement, and close hole steel wire is fixed on framework of steel reinforcement with tied silk and constitutes close hole steel wire net rack.
Preferably, in step 3, steel plate for sealing water is fixed on the method for the close hole steel wire net rack of lower layer using spot welding, and
Welding, which cannot weld, hinders burn-through steel plate for sealing water.
Preferably, in step 4, after common water-proof concrete casting complete, close hole steel wire net rack and water-stopping steel are checked
Whether plate is reinforced because concreting generates movement if any movement at any time.
Preferably, in step 5, layer pico- arch camber highest point in microdilatancy water-proof concrete face is than common waterproof when receiving light
Concrete, which is higher by 3~5cm, to be advisable.
Preferably, the thickness of the steel plate for sealing water is 3mm.
As can be seen from the above technical solutions, compared with prior art, the present invention has the following technical effects：
1) microlith water-proof concrete item is arranged between base and lower layer's reinforcing bar, highly with lower layer's thickness of protection tier,
Length along the elongated setting in post-cast strip, can prevent the concrete of post-cast strip both sides from due to structure reinforcing bars separate close hole steel wire without
Method is installed in place and is flowed into post-cast strip in gap between the bed course and structure reinforcing bars that generate, also serves as the protective layer of lower layer's reinforcing bar
Cushion block.
2) it microlith water-proof concrete item, close hole steel wire net rack and hangs mould one and works after tunneling boring has blocked from top to bottom and pour
With the excessive of both sides concrete, it is effectively guaranteed the construction quality of post-cast strip.
3) steel plate for sealing water be arranged among structural slab to the microdilatancy water-proof concrete in post-cast strip can and post-cast strip two
The connection of the common water-proof concrete of side plays booster action, can be effective against uneven settlement of foundation and sole plate is anti-
The effects that floating, influences post-cast strip and both sides concrete generates differential settlement, while steel plate for sealing water is arranged in post empiricism seam portion
Position substantially prolongs infiltration circuit.
4) concrete of two layers of steel plate for sealing water and post-cast strip is combined closely, and to play the role of good cracking resistance impervious.
5) layer pico- arch camber in post-cast strip inner concrete face when receiving light after the completion of the concreting of post-cast strip, in this way can be on top
Water can quickly flow away in the case of meeting water, play good drainage.
