Detailed Description
The invention is further described below, but the scope of protection of the invention is not limited thereto:
the invention relates to a novel construction method for a sponge type large-area planting laminated plate roof, which comprises the following steps:
1) preparation before construction: preparing materials, instruments and the like for standby;
2) inspecting the laminated slab before installation: checking the horizontal elevation of the support: and measuring the top surface elevations of the horizontal ridges of the wall, the beam and the frame body from two different observation points by using a measuring instrument, wherein when the laminated slab is installed, the maximum allowable value of the height of the supporting top is L/700 and is less than or equal to 5mm, 5mm is on the horizontal line, and 5mm is below the horizontal line.
3) Setting a laminated slab support: the phi 48 multiplied by 2.75mm full steel pipe fastener type scaffold has the vertical and horizontal distances of the upright posts of 1000mm, the step distance of the scaffold of 1.8m, and the supports are erected in a mode of sharing the beam plate and the upright posts. 38 multiplied by 88 battens are fully paved on the horizontal steel pipe at the top of the laminated slab support, the distance is 250mm, 915 multiplied by 1830 plywood templates with the thickness of 13mm are fully paved on the laminated slab support, the laminated slab support in the middle skip layer area of 23-24/C-F shafts of 1# main building, 18-19/L-N shafts of 1# skirt house and 11-12/C-F shafts of 2# skirt house is in a high formwork supporting range, the full steel pipe fastener type scaffold with the vertical and transverse distances of 900mm is supported, and the step distance of the scaffold is 1.5 m. The support is built in a mode of sharing beam plates and upright columns.
4) Hoisting the laminated slab: the laminated slab is hoisted by a tower crane, 4 hoisting points are used for hoisting each floor slab, and lifting hooks are embedded at the positions of the hoisting points. The hoisting cable chain adopts a special cable chain and 4 closed lifting hooks, the stress is averagely shared, the multipoint balanced hoisting is carried out, the length of a single cable chain is not less than 4m, the gravity centers of a main lifting hook, a hoisting tool and a component of the hoisting equipment are ensured to be superposed in the vertical direction in the hoisting process, the horizontal included angle between the hoisting cable and the component is not less than 60 degrees, the stability is ensured as much as possible in the hoisting process, the inclination and the large-amplitude swing are avoided, the horizontal component is hoisted to about 200mm away from the ground in the hoisting process, whether the hoisting cable has a skew twist or a clamping phenomenon or not and the stress of each hoisting point is uniform in hovering inspection, when the installation position of the composite slab component is close to 600mm, the component is supported by hand and then slowly descends to be in place, the component is hoisted to the same direction in sequence, and the prefabricated composite slab is hoisted slowly to avoid impact; the method comprises the steps of entering a seat according to a design drawing or a mounting layout of the laminated slab, slightly adjusting alignment according to the laying length of a support required by the drawing by using a crowbar, tightening a lifting rope by using a tower crane if necessary, arranging anchoring steel bars thrown out from two ends of the prefabricated laminated slab in time after the prefabricated laminated slab is mounted in place, connecting the anchoring steel bars of the laminated floor slab with opposite plate steel bars, and preventing the floor slab from being bent upwards or downwards to be vertical to the surface of the plate and pressing the floor slab below the plate. And the length of the anchoring reinforcing steel bar extending over the center line of the beam is ensured to be not less than 5d, after the floor slab is laid, the lower edge of the slab should not be uneven, gaps should not appear, gaps at the positions of the supports which cannot be locally adjusted and avoided should be plugged, and the supporting upright rods can be properly adjusted, so that the bottom surface of the slab is kept flat and seamless.
5) Installing upper-layer steel bars of the floor slab: 1/water and electricity pipeline lays and inspects qualified back installation floor upper reinforcing bar, roof reinforcing bar lays the direction and lays according to the construction scheme, because of the truss direction is different, require lower floor's reinforcing bar to lay under the truss, it is inseparable to combine with prefabricated floor to water the layer after guaranteeing, for reinforcing bar and the template that the protection has been laid, lay the wooden springboard when inspection is accepted and concreting is gone up in order to avoid the reinforcing bar to receive to trample and cause the reinforcing bar protective layer to be too thick, the reinforcing bar must not cut off at will, need to break the reinforcing bar with the fingers and thumb in order to guarantee that the reinforcing bar is complete if the entrance to a cave.
6) Pouring a concrete leveling layer: before concrete pouring, sundries on the laminated floor slab should be cleaned and sprinkled with water for moistening, but no open water should be used. The concrete of the superposed layer is compactly vibrated to ensure that the superposed layer and the prefabricated layer are combined into a whole, after the post-cast layer is poured, the plastic film is adopted for covering and curing for 8-12 h, the curing time is at least 7d, the curing time can be prolonged when the temperature is the highest in summer, the concrete pouring mix proportion and the heat preservation measure are paid attention to during the construction in winter, and the construction in winter is avoided as far as possible because the post-cast layer is thinner.
7) Setting a steam-isolating layer: the PE film is selected as the steam-proof layer in the steel structure roof system, the proper thickness of the PE film is 0.3 mm, the rubber adhesive tape is adopted to process the seam of the PE film in the construction process, the steam-proof layer is guaranteed to be airtight, and meanwhile the PE film on the peripheral equal details and the whole roof are guaranteed to form an airtight whole.
8) Laying a sponge type planting layer module: the material for laying the filter layer is preferably 150g of non-woven fabric and ceramsite, so that the water permeability and air permeability of the movable greening module are ensured, and the non-woven geotextile roll is prevented from being damaged before being installed and unfolded. The geotextile rolls are piled in flat places without water accumulation, the pile height is not more than four rolls, and the geotextile rolls are required to be covered by opaque materials to prevent ultraviolet aging. The integrity of the label is kept during the carrying and storing processes of the geotextile, the handwriting is clear and recognizable, a worker can cut the geotextile after straightening two sides when cutting the non-woven fabric, a layer of ceramsite is paved at the bottom of the container, 150g of non-woven fabric is paved, the total thickness is 10 mm-20 mm, a matrix is paved, the matrix is uniformly paved in a movable greening module in advance before planting, the thickness is generally 80-100 mm, the greening module adopts a special roof greening planting matrix, a keel is paved, and angle steel is used as a supporting clamping groove at the back on the roof anti-skid shelter to serve as a welding foundation. The length of the foundation angle steel is 10 mm-20 mm longer than the width of the angle steel, one edge of the foundation angle steel is aligned with the anti-skidding shielding during welding, the foundation angle steel is welded in a lap-joint welding mode, 1-3 layers of side welding seams are welded between the steel bar and an angle steel base plate, the welding seams are full, the surfaces of the welding seams do not have defects or weakening phenomena, the supporting angle steel and the foundation angle steel can be welded after the foundation angle steel is welded and checked to be correct, and the lap-joint welding mode is mainly used in the same way.
