As Fig. 3, before channel-section steel is installed: look for absolute altitude, play the surface layer horizon, by had on the metope+the horizontal absolute altitude line of 50cm, promptly build the absolute altitude line, measure the horizon of ground surface layer, bullet around on the metope, and require corridor beyond the room, landing, the absolute altitude of marking time echoes mutually, connects consistent; Base treatment: concrete floor 18 plucking during structure construction, need the dust cleaning totally, the laitance coating that will be bonded in the basic unit shovels then, with buck greasy dirt is brushed, and with clear water basic unit is rinsed well at last; It is moistening to sprinkle water: sprinkle water moistening the previous day at the pouring construction surface concrete to substrate surface, base treatment and watering are moistening, and that concrete construction face is prevented that the mass defect in hollowing and crack from exerting an influence is very big, must carry out in strict accordance with technological requirement in the construction.
As Fig. 4, described utility model comprises machine cuts working face cut-off rule 12, and adjustment height base 13 usefulness Φ 14 screw expansion screws 11 are squeezed in the floor, channel-section steel 1, and first castable 14, last castable 15 is every striding castable 16.
As Fig. 3, this is the most critical place that is related to the concrete construction surface evenness, physical strength and the hardness of considering mould are the cores of control working face planeness, the utility model has been abandoned the absolute altitude mould of traditional employing high strength cement mortar floating screed as concrete construction face, adopt channel-section steel 1, be made into adjustment height base 13 channel-section steel moulds; Effective selection of channel-section steel mould has also been created good " track " for the use of evener.
Two channel-section steel distances: two channel columns are channel-section steel thickness apart from adding 60mm, add the thickness that 30mm is an extruded sheet 3 again; Adjustment height base 13 usefulness Φ 14 screw expansion screws 11 are squeezed in the floor, and adjustment height base 13 is being provided with apart from every channel-section steel 400mm place, 1 two ends and middle part, totally three channel-section steels 1.
As Fig. 2, nut is welded with steel plate 6 soldering and sealing, middle part punching in the termination, steel plate 6 and frame column dieback; Nut 7 is dead with screw rod 8 welderings, screw terminal 17.In order to prevent in the working face concreting process that channel-section steel 1 tilts, the spy is provided with adjustable terminations at channel-section steel 1 two ends and is fixed on the concrete column 9, increases the stability of channel-section steel mold integral.
As Fig. 1, it be direct cutting concrete or reserve ways such as batten that tradition is divided slot, and the inside concrete after can occurring cutting apart seaming and cutting and cutting picks that to cut a hole difficulty big, need spend a large amount of labours; Or batten takes out comparatively difficulty, cuts apart defectives such as tape edge is comparatively crude and not straight after the moulding simultaneously.Cutting apart seaming and cutting for the ease of concrete construction face cuts with inner concrete and picks cutter, the utility model has been innovated the branch slot and has been kept somewhere new method, be after adjustable channel-section steel mould installs, 15mm extruded sheet 3 is pasted channel-section steel 1 side, be noted that especially extruded sheet 3 is apart from channel-section steel upper surface 10mm, be convenient to keep divide the straight attractive in appearance of slot after the moulding, should notice that simultaneously it must be the thickness that mast axis adds half extruded sheet 3 that channel-section steel is laid the position, sideline, thick extruded sheet 3 riding positions of 15mm are just in time promptly divided the centre position of slot for the axis center like this, concrete construction joint also just in time in minute slot, has avoided the concrete construction joint place crack to occur effectively.
After the channel-section steel mould all installs and fixes, building before the pea gravel concreten working face, in moistening basic unit brush together 1: 0.4~0.5 (cement: plain-water slurry water), Shua area is not excessive, to avoid the air-dry surface layer hollowing that causes of overlong time cement paste with brush with the shop pea gravel concreten.
In Fig. 5-1 and 5-2, machine cuts working face cut-off rule 12 uses schematic diagram as among Fig. 5-2, the wide machine cuts seam 19 of 2mm, and the wide cutter scope 20 of manually picking of 16mm, seam material 21, working face thickness 2, reinforced concrete floor 18 are passed through in filling in the seam.
Because one-time-concreting concrete construction face width degree is that a post is striden, the concrete smoother is proposed requirements at the higher level, aluminium floating rule or aluminium beam rigidity commonly used at present all can't satisfy the leveling needs, perhaps too heavy operating difficulties, this engineering has been introduced the small-sized evener of automation, the leveling bar is the long jack truss of 9m, directly is free to move the double action that has leveling and vibrate above the channel-section steel mould of both sides.
Vibrating in press polish limit, small-sized evener limit, for the first time in burnishing process, spreads out and puts on concrete more than establishing 3 people, will cheat recess and fill and lead up, and protruding place is evened out.The concrete that mainly vibrates of press polish for the second time.Around pillar, in the middle of the post evener press less than the place pave with spade, firmly smear pressure with wood float again.
Behind the working face concrete initial set, the people steps on, and footprint is arranged but when not sinking, carries out troweling with finisher, will all smear line pressing, compacting, press polish.
Working face press polish completion back 24h covers the watering maintenance with gunnysack, keeps moistening.Curing time is no less than 7d, notes not allowing ballast and collision between curing time.When concrete reach intensity 50% the time can the cutting slot, unsuitable indwelling time is oversize, otherwise the ultra-long concrete working face can produce cracking.Dividing slot is 20mm, and machine cuts seam 19 is 2mm, manually picks cutter scope 20 and is 16mm.Because in advance at joint-cutting position of sound production extruded sheet 3, promptly made things convenient for joint-cutting, also make things convenient for and behind joint-cutting, the concrete slag is removed and do not needed to pick the staking inner concrete, also guaranteed to divide the no burr straight, attractive in appearance of slot simultaneously.After treating that concrete strength reaches requirement, the gravel-concrete between the cleaning seam adopts special-purpose caulking material to tamp in the seam.
