Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the present invention is further detailed explanation.
Consult shown in Fig. 1 and Fig. 2, construction elevator basis 21 is positioned in structure roof 22, and of the present invention oneKind construction elevator strengthening of foundation device 1 is supported between structure roof 22 and understructure 23 reinforces this structureTop board 22. Bracing means 1 of the present invention comprises what four support with adjustables 11 and four diameters were 110mmSupporting steel tubing string 12, supporting steel tubing string 12 is supported between structure roof 22 and understructure 23, adjustableBearing 11 is located between the lower end of supporting steel tubing string 12 and the upper surface of understructure 23. Support with adjustable 11Upper end be provided with adjusting screw(rod) 112 and form, the lower end of supporting steel tubing string 12 is respectively equipped with an adjustable plate 113,On adjustable plate 113, offer the screwed hole mutually screwing togather with adjusting screw(rod) 112, by regulating support with adjustable11 regulate the height of supporting steel tubing string 12, thereby make the upper end abutting structure top board 22 of supporting steel tubing string 12Lower surface. Between the upper end of supporting steel tubing string 12 and the lower surface of structure roof 22, be further welded withThe steel plate cushion block 16 of thick 20mm, it is of a size of 250mm × 250mm. Between four supporting steel tubing strings 12Horizontal brace 14 and diagonal brace 15 its support reinforcements are set. Four supporting steel tubing strings 12 are all placed on construction elevatorUnder shaped steel foundation beam. Shown in Fig. 3, it is new that structure roof below is at least provided with 2 layers of this practicality from top to bottomThe bracing means 1 of type, and the bracing means 1 arranging on every floor will ensure in supporting steel tubing string 12 in the heartUnder on a vertical line. The reinforcement measure that adopts construction elevator strengthening of foundation device 1 of the present invention, has reached guarantorCard construction quality, shortens the construction period, saves the effect of financial cost.
Now with set up full hall scaffold reinforce and apply construction elevator strengthening of foundation device of the present invention carry out throughJi performance analysis.
If 1 adopts the mode of setting up full hall scaffold, structure roof is reinforced: Area of bearing 6.0m× 6.0m, adopts Φ 48, the steel pipe of wall thickness 3.0. Use altogether 16# channel-section steel, 6m × 4 (root) × 19.752 (kg/ m) × 3 (layer)=1422kg; Full hall scaffold vertical pole ' s span 0.6m, every layer uses vertical rod is 121,Liftoff 10cm arranges the bar of sweeping the floor together, and steel pipe length is 6 × 11=66m; The vertical cross-tie of twice is set, steelLength of tube is 66 × 2 × 2=264m; The vertical bridging of twice is set, and using steel pipe length is 24m, every layerUse 121 of jackings;-3 layers use the long vertical rod of 5m, use altogether steel pipe length to be: 121 × 5=605m;-2Layer uses the long vertical rod of 5m, uses altogether steel pipe length for 605m;-1 layer uses the long vertical rod of 4.5m, uses altogetherSteel pipe length is: 121 × 4.5=544.5m.
To sum up, adopt full hall scaffold to support structural slab, need material as follows:
(1) 16# channel-section steel, 1.422t; 4500 yuan × 1.422t=6400 unit;
(2) use altogether steel pipe: 605+605+544.5+24+264+66=2108.5m, with the calculating of 18 months rental periods,Need hire charge: 2108.5 × 0.02 × 30 × 18=22771.8 unit; Need altogether fastener hire charge: 121 × 3 × 3 ×0.012 × 30 × 18=7056.72 unit; Jacking hire charge: 121 × 3 × 0.03 × 30 × 18=5880.6 unit; Freight charges3000 yuan
Amount to: 22771.8+7056.72+5880.6+3000=38709.12 unit.
(3) set up, remove (containing having bad luck material) and need altogether labour cost:
5 work day × 4 day × 2 (take, tear open) × 200=8000 units.
Above three totals: 6400+38709.12+8000=53109.12 unit, needs 8 days durations.
If 2 adopt construction elevator strengthening of foundation device of the present invention, structural slab is reinforced: need altogether materialAs follows:
(1), the steel pipe of diameter 110mm: 4 × 5+4 × 5+4 × 4.5=58m; Diagonal brace, cross bar amount to 45Rice. 20 × (58+45) × 4.5=9270 unit.
(2), 50 jacking 4 × 3=12. Keep in mind with each 150 yuan, need altogether: 150 × 12=1800 unit.
(3), set up, remove labour cost: 2 × 0.5 × 200 × 2=400 unit, it is 300 yuan that freight charges are kept in mind.
Need altogether expense: 9270+1800+700=11770 unit.
Reduce expenses: 53109.12-11770=41339.12 unit, 7 days reductions of erection time.
Indulge the above: adopt construction elevator strengthening of foundation unit engineering of the present invention to save altogether more than 40,000 yuan, improveOperating efficiency, shortened the duration.
Below embodiment has been described in detail the present invention by reference to the accompanying drawings, and those skilled in the art canAccording to the above description the present invention is made to many variations example. Thereby some details in embodiment should not formLimitation of the invention, the present invention by the scope defining using appended claims as protection model of the present inventionEnclose.
