Description
Technical field
A kind of terrace construction technique belongs to floor construction technical field, relates generally to a kind of concrete abrasion-resistant floor construction work
Skill.
Background technology
The service range of terrace is modern industrial enterprises terrace, business terrace, big-and-middle-sized parking lot terrace, garage parking
Level ground, commercial square, station terminal, school's sports ground, logistics warehouse terrace, hospital's terrace, office's terrace, swimming pool terrace,
Tourist attraction terrace, various recreation centers terrace, various research and development fields terrace, in a word, as long as using the ground of concrete
Level ground face can make terrace, and terrace has that anti-pressure ability is strong, wear-resistant Chengdu is high, dust-proof, grease proofing, impermeabilisation, easy to clean etc.
Premium properties, in actual applications using more and more extensively, however, terrace is urgently to be resolved hurrily in the presence of some in work progress
The problem of, for example terrace generation crack, poor toughness, anti-fatigue ability are low, and tensile strength is low, shock resistance fragmentation, later maintenance dimension
Accomplish this height, terrace service life is short.
The content of the invention
In order to solve the above problems, the invention discloses a kind of concrete abrasion-resistant terrace construction technique, terrace is enhanced
Toughness, crack resistance are strong, anti-fatigue ability is high, extend the service life of terrace.
The object of the present invention is achieved like this：
A kind of concrete abrasion-resistant terrace construction technique, comprises the following steps：
Step one：Base treatment：Basic unit is cleared up, absolute altitude is carried out and compacting is constructed；
Step 2：Template is laid：Template laying is carried out according to concrete point bin location；
Step 3：Concreting：Constructed using sequence placing mode；
Step 4：Leveling, is constructed using being flattened from periphery to center centralized system, and concrete surface flatness is met construction will
Ask；
Step 5：Wearing layer, the spreading of three progress high-abrasive materials of part are laid, and is carried out levelling.
Step 6：Maintenance：Sealing compound is sprayed, cracking is prevented；
Step 7：The slot cementation of fissures is constructed.
The detailed process of base treatment described in step one includes：Base cleaning is clean；Bottom element soil is compacted；Paving
If broken sandstone simultaneously and is conserved.
The plain soil compaction coefficient is 0.95, and flatness scope is 0-3mm.
Step 3 specifically includes procedure below：The double-deck polypropylene isolated film of laying；The preparation of concrete；Poured using a point storehouse
The method of building is poured；Progress is vibrated levelling.
The preparation method of the concrete includes：Steel fibre, sand and rubble are stirred；Once add in stirring thing
Add water mud, flyash, zeolite powder, silicon ash water and auxiliary agent is stirred.
The slump of the concrete is less than 5cm,.
Step 5 is specifically included：When concrete initial set is to 50%-60%, one layer of quartz sand particle is dispensed；Carry out floating carry
Slurry, it is 0-3mm to make its flatness；Second of quartz sand particle spreading is carried out, floating warehouse, flatness reaches 0-3mm；Carry out the
Three times quartz sand particle is dispensed, and floating warehouse, flatness reaches 0-2mm.
The ratio between consumption of three spreadings quartz sand particle is 4:1:1.
Step 7 is specifically included：After concreting 30h-60h, lancing operation is carried out, deep and concrete thickness ratio is stitched
For between 1/3-3/5.
The slit width is 3-5mm.
The present invention compared with prior art, has the advantages that steel fibre is abundant and is uniformly filled in coagulation
Each place of soil, is improved terrace toughness, using the terrace high mechanical properties of construction technology of the present invention, solves coagulation
Soil criticize occur cracking, hollowing, flake, flatness not enough etc. quality problems, reduce cost, and reduce the later stage
The service life of maintenance cost and extension terrace, without assembling reinforcement, in casting and compacting of concrete, it is not necessary to pump, improves and pours
Speed, easy construction, without large-scale construction equipment, low cost, speed of application is fast, short time limit, with better economy effect
Benefit；Rolled steel dosage reduction power consumption is reduced, low-carbon environment-friendly economizes on resources.
Embodiment
The specific embodiment of the invention is described in further detail below.
A kind of concrete abrasion-resistant terrace construction technique of the present embodiment, comprises the following steps：
Step one：Base treatment：Base cleaning is clean；Bottom element soil is compacted, the plain soil compaction coefficient is
0.95, flatness scope is 0-3mm；The broken sandstone of 15mm-30mm specifications is laid, laying depth is 20mm, and coefficient of loose laying is
1.2, it is compacted using 20t road rollers, compacting factor is more than in 0.95, compacting process according to actual needs, is moistened on a small quantity
It is wet；0-15mm year sandstone is laid, thickness is 40mm, compacting is entered using road roller, carry out gap filling and levelling, laying is completed
Conserved afterwards, the broken sandstone is the crushed-gravel that sand content is 3%,
Step 2：Template is laid：Template laying is carried out according to concrete point bin location, using the side form of channel-section steel seat concrete, and
Fixed using triangular reinforced bar support；During formwork, the upper flat absolute altitude of template is consistent with bottom surface absolute altitude；
Step 3：Concreting：Constructed, specifically included using sequence placing mode：Lay the thick polypropylene of bilayer 0.15mm
Provided with the epoxy glue layer that 0.1mm is thick between film, two layers of polypropylene film；Using double-deck isolated film as an entirety,
Prevent occurring misplacing in work progress and breakage, meanwhile, epoxy glue layer has good insulation and toughness, to the later stage
Concrete pour with good basic effect；
Transmission rod is installed, sets up straight by spacing of the power transmission between dry and transmission rod on locating template, locating template in template both sides
Footpath is drilled, and transmission rod one end is fixed for one section, the transmission rod is uniformly arranged in transmission rod through drilling by spot welding with support
At terrace plate thickness 1/2；The transmission rod is vertical with locating template, and the outside of transmission rod brushes pitch and carries out colligation again in advance
On support,
The preparation of concrete：Steel fibre, sand and rubble are stirred；Cement, flyash, boiling are once added in stirring thing
