Abstract
The invention discloses a kind of the old and new's flat-top cracked concrete construction method, processing method is comprised the steps of: being checked, is made marks, preparing waterproof material and construction, checking whether leak after construction.Construction method disclosed by the invention has good leakproofness and globality, and flat-top is avoided to crack from the negative again in the future.
Description
Technical field
The present invention relates to the realm of building construction, and in particular to a kind of the old and new's flat-top cracked concrete construction method.
Background technique
The method of the bottom plate of traditional flat roof, top plate and exterior wall crack resistence is divided into post-cast strip in conjunction with the seamed of deformation joint
Formula design method and post-cast strip or reinforcing strip combination concrete add two kinds of gapless design method of swelling agent, and cracking is necessarily brought
The problem of leak.Thus waterproof is exactly a fresh topic always, whether tunnel, bridge, road, build or our days
The house often lived, waterproof all can not be ignored.Construction method of the present invention is suitable for: new flat-top cracks, old flat-top cracking does not drop,
Old flat top surface aging is serious but situations such as tenesmus.
Summary of the invention
To overcome above-mentioned deficiency, the object of the invention provides a kind of the old and new's flat-top cracked concrete construction method.
The solution of the present invention is as follows: a kind of the old and new's flat-top cracked concrete construction method, the construction method includes following
Step:
(1) polish: casting concrete flat-top checks whether there is cracking phenomena to the comprehensive polishing of flat-top after demoulding；
(2) it marks: 6-8 long drill bit is installed on electric hammer, cracking point both ends are up punched from the negative, according to bit model
Difference at most makes a call to three eyes, is then penetrated in eye, marked with 7 word steel；
(3) preparation waterproof material: cement, thick sub- sand and old stone are mixed into concrete by 1:3:3；
(4) telescopic steel pipe, jack and jump frame are put up at flat-top reverse side cracking, is cracked with black mark-line in reverse side flat-top
Point locates two black mark-lines of bullet toward each 12cm in both sides, long to be no more than 3.26m, black mark-line bullet well total 24cm wide；
(5) blade is controlled in 5mm depth with machine for cutting floor bricks, is then cut from two black mark-lines toward centre, cuts one layer of electricity consumption
Light one layer of the shovel of shovel, the most 3cm of reverse side flat-top cut-in groove are deep, and when cutting places a high-power hair dryer simultaneously and siphons away dust；
(6) toward each 25cm in both sides, two black mark-lines of bullet, each long 3.5m of two black mark-lines are positive again at the flat-top cracking of front
Cracking point groove is cut in the presence of water, and after positive 3cm depth concrete is cut, 7cm is recycled after cleaning out, is continued down
3cm depth is cut, and slightly spade is fallen with tool, washes that open washing is straight, and cracking point is straight toward both sides difference 25cm black mark-line in front
It is access at lower 6cm, cutting machine-cut slightly shovels less than 6cm depth with tool, and 6cm deep shovels oblique groove at an oblique groove
When, power shovel toward at recycling 7cm sideling toward shoveling at 25cm black mark-line；
(7) with electric hammer by upper drill bit on collar tie beam down symmetrically bore four drilling eyes, eye depth 2cm, slightly by flat steel reinforcement cage
Curve half-moon-shaped, the drilling eye that both ends are respectively aligned to collar tie beam both ends is inserted into, and some arches is played, above and below upper and lower 6 screw-thread steels
It hooks, one is hooked in the main reinforcement of flat-roofed house, and one is hooked on the flat steel reinforcement cage of arch, according to the orientation of main reinforcement, sets at every 10cm
One is set, the position of 50cm wide puts in after being placed on that flat-top is suitable for reading with 6 screw-thread steels and cutting through, by hand hammer jail, often
One is arranged at 15cm, forms a steel mesh；
(8) band steel muscle cage bottom lower template is made with jack in reverse side, template gap is filled up with weaved cotton cloth, with big function
Rate hair dryer blows away dust, and concrete is stirred, and dilutes after-pouring at flat-top tieing, and slurry concrete pours small with 220v afterwards
Type vibrating head shakes concrete tightly, is polished concrete with nog plate；
(9) after concreting is good, naturally dry；
(10) Fang Chi that a wide 70cm, high 10cm, long 4m are built at concreting fills water to beat tide and inspection
It tests.
A kind of above-mentioned the old and new's flat-top cracked concrete construction method, tool in the step (6) by hand chisel or
Power shovel.
Beneficial effects of the present invention: it is positive and negative to solve flat-top for a kind of the old and new's flat-top cracked concrete construction method of the present invention
The problem of leak is cracked repeatedly in face, entire waterproof work have good leakproofness and globality, flat-top reverse side are avoided to crack.
