Abstract
The invention relates to a construction method for a roof, in particular to a concrete construction method for a large parking roof. The concrete construction method for the large parking roof can solve the technical problems in construction for the parking roof, and comprises the following steps: clearing a base layer, laying a polypropylene fabric protective layer, surveying and setting out, snapping a line, sloping, pulling the line, manufacturing a dividing joint, binding steel bars, placing a cushion block of the protective layer, watering, humidifying, pouring concrete, finishing the surface, maintaining, resecting an extruded sheet at the dividing joint, pouring sealing paste and performing inspection and acceptance. The construction method is characterized in that the extruded sheet is sandwiched in a concrete conical rushed tape as the dividing joint for forming divided blocks in uniform size for pouring concrete, thereby not only solving the problem of formwork support, and improving the efficiency, but also ensuring the quality.
Description
Technical field
The present invention relates to a kind of job practices that is used for roofing, be specially a kind of job practices of the large-scale roofing concrete of parking.
Background technology
With respect to common roofing, the quality of the roofing requirement of parking is higher, and desired concrete thickness is also bigger, generally will cover a layer concrete again on common roofing.Traditional parking during the roofing concrete surface construction, prop up mold materials mainly based on wooden model, punching block, there is the defective of support system complexity, destructible waterproofing course, finished product corner angle destructible in these formwork ways, especially grasp for draining roof pitch in a organized way is extremely difficult, and the construction effect is low, cost is high.The job practices of developing a kind of novel large-scale roofing concrete of parking has become problem demanding prompt solution.
Summary of the invention
The present invention provides a kind of job practices of the large-scale roofing concrete of parking for the technical problem of the construction that solves the roofing of parking.
Job practices of the present invention is realized by following technical scheme: a kind of job practices of the large-scale roofing concrete of parking; step is that base cleaning is also spread the Polypropylene topping, measures unwrapping wire; snap the line is looked for the slope; backguy, make the lattice seam, assembling reinforcement, put the topping cushion block, it is moistening to water; build concrete, receive the face maintenance; the extruded sheet at lattice seam place excises downwards, and perfusion sealing compound is checked and accepted.
The present invention adopts density to be not less than 30Kg/m
3Extruded sheet stitch bar as lattice, spacing 5m, the C25 pea gravel concreten taper floating screed band of the wide 100mm of each shop fixtures of plate both sides carries out concrete with this formwork way and builds, and concrete solidifies the back and forms piecemeal limit mould naturally, build concrete then, its feature is to adopt extruded sheet to be clipped in the concrete taper to rush in and do the lattice seam in the band, forms lattice piece of uniform size and comes concreting, has both solved a modulus problem, improve efficient, guaranteed quality again.
Description of drawings
Fig. 1 is a roofing surface structure schematic diagram of the present invention,
Fig. 2 is one of roofing tangent plane structural representation of the present invention,
Fig. 3 is two of a roofing tangent plane structural representation of the present invention.
Among the figure: 1-lattice seam, 2-basic unit, 3-Polypropylene topping, 4-concrete, 5-reinforcing bar, 6-concrete floating screed band, 7-extruded sheet, 8-topping cushion block, 9-sealing compound.
The specific embodiment
Meaning as shown in the figure, a kind of job practices of the large-scale roofing concrete of parking, step be,
1, shop, basic unit 2 cleaning back Polypropylene topping 3, and basic level requirement cleans out the foreign material in the basic unit to ensure the quality of products, and basic unit is the SBS waterproof roll, must keep coiled material not have destruction.Spread Polypropylene topping preparation cement paste, lay polyethylene polypropylene cloth topping, protection bottom coiled material is not destroyed, and Polypropylene overlaps all 〉=50mm.
2, measure unwrapping wire, snap the line is looked for the slope; According to the roofing Design Requirement Drawing, drainage grade is 1%, and the design drain gully amounts to 20, according to the dividing ridge, roofing is divided into 20 bulks, each piece is the central plan drainage grade with the drain gully, eject grade line on parapet top, the interim patch block cake in middle part is looked for the slope.
3, backguy and utilize extruded sheet 7 to make lattices seam 1, look for the slope according to institute's patch block cake backguy, backguy is that 120mm is thick with the concrete consistency of thickness highly in theory, and extruded sheet 7 highly is 100mm, and the thick operation leeway of 20mm (extruded sheet intensity is more than the 30Kg/ ) is left in the bottom.Bottom, the every limits of extruded sheet 7 is fixing with the wide C25 taper pea gravel concreten floating screed band 6 of 100mm, to form in length and breadth the lattice piece to spacing 5m.Require this moment about the outstanding concrete floating screed bands 6 outer 30mm of assurance of extruded sheet 7, extruded sheet thickness is wide with designing requirement lattice seam, and it is thick to be 20mm.
4, assembling reinforcement 5, put topping cushion block 8, bar gauge, spacing are φ 8@250, carry out colligation at each lattice piece place, and 40mm spacer spacing 800mm places.
5, water moistening; watering moistening is a preceding most important work of concreting; except that the satisfied moistening requirement of a segment base layer; main because of summer high temperature at a time when the construction; Polypropylene topping bottom is SBS waterproof roll and plastic extrusion heated board; easily accumulation of heat is watered and can be reduced a part of basic unit temperature.
6, build concrete 4, the maintenance of receipts face, because the bottom is waterproofing course and extruded sheet insulation layer, so concrete is had special requirement, merchant's concrete sand coarse aggregate ratio is little, and it is big that coarse aggregate content is wanted, in the water/binder ratio 0.5, about slump 130mm, must add retarding agent, to slow down the rate of release of bottom water heat-transmission.
Avoid the high temperature period at noon, take to build in morning, afternoon operation, build in the process, taper concrete floating screed band waters moistening at any time, be beneficial to concrete combination, during the lattice that vibrates seam floating screed band periphery, guarantee in the vibrating spear oscillating region, to get final product, must not cross herein and shake, in case segregation has influence on lattice seam place intensity.Behind the vibration compacting, two human 6m darbys adopt the mode of low raising shovel that the gradient is found out along dividing strip.Before the final set, concrete surface is received face 3 times at least with disk sander.If concrete part, lattice seam place is a dry state, needs to clap the slurry press polish and handle with plasterer's trowel.After the final set, cotton-wadded quilt covers timely water seasoning, because concrete admixture retarding agent, curing time is no less than 14d.
7, the extruded sheet 7 at lattice seam place excises downwards, and concreting is intact, and the lattice portion of sewing on is regular naturally after 7 days splits, with the wallpaper cutter along lattice seam rejecting 15mm downwards.
8, perfusion sealing compound 9 is checked and accepted.Concreting is intact poured into sealing compound after 28 days in the lattice seam of rejecting, sealing compound is pressed into the concave surface seam with autocratic tooled joint rod in the lattice seam.
