In order to guarantee result of use and to save material, described reinforced concrete body internal upper part has D=25 pull bar preformed hole 8, and bottom has the reserved hole for hoist 10 of D=50; Described corrosion resistant plate 1 is thick is 1mm, and the bondline thickness of steel bonding glue 2 is 0.5mm, and general steel plate 3 is that thick 6mm is just dull and stereotyped; Described channel-section steel spacer bar 4 diameters are 12mm(Φ 12), stiffener 6 diameters are 12mm(Φ 12), ring muscle 9 diameters are 6mm(Φ 6), stiffener 11 diameters in bottom are 16mm(Φ 16); Described channel-section steel 7 is 50 channel-section steels, and built-in fitting 12 is L50 angle steel.
When the utility model is used, through pre-embedded steel slab and Cast-in-place concrete basis 14, be fixed together, segmentation is carried out prefabricated.
The utility model innovation is loose tool plate at the bottom of prefabricate reinforced concrete, at general steel plate or be directly coated with steel bonding glue on concrete bed die, paste thin corrosion resistant plate (as the corrosion resistant plate of 1mm or 0.4-0.6mm), the technical problem that it is difficult that the end template of spending less money to solve concrete prefabricated parts is constructed, the utility model adopts the very thin corrosion resistant plate of normal thick steel sticking, or in other hard substrate the construction technology of the corrosion resistant plate of album leave, also can be used for the construction in other field, market segment is open, economic benefits, prefabricated box beam, T-shaped beam, the end loose tool plate that cored slab is used, the conventional cast-in-situ reinforced concrete that adopts is constructed, change loose tool plate at the bottom of prefabricate reinforced concrete into, installation forming construction again, member is produced loose tool plate of the complete end and can be transported to new production site after dismountable and reinstall to use, reach reusing of end loose tool, can cost saving, reduce building waste, accelerating construction progress, be beneficial to environmental protection, and obtained extraordinary useful technique effect through practical probation, interrelated data is as follows,
Existing prefabricated box beam, T-shaped beam, is bonded in the corrosion resistant plate of thickness 1MM on original or newly-built end loose tool plate surface layer with steel plate glue above loose tool on loose tool or at the bottom of newly-built reinforced concrete at the bottom of cored slab, spends minimum money to reach the effect of stainless steel end template.Specifically:
Clean cleaning with water above loose tool plate,, after anhydrous parching, to require tyre surface flatness to be less than 1 millimeter, flatness is greater than 1 millimeter, increase adhesive glue consumption.Being ready to thickness is 1 millimeter, width is that 996 millimeters (for 30 rice bin beams) or width are 496 millimeters (for 30 meters of T beams), length is the corrosion resistant plate of 1500 millimeters, and every section of reinforced concrete bed die is prepared 2 corrosion resistant plates, and HD657 adhesive is at every turn by 1.5 kilograms, criticize and be put on end loose tool surface layer, THICKNESS CONTROL is at 1-2 millimeter, batch floating whole after, corrosion resistant plate compacting is installed, guarantee that the corrosion resistant plate of installing is smooth, straight.Solidify 48 hours;
Cost analysis is as follows: the every weight per square meter of thick material 304 corrosion resistant plate of 1MM is 7.93 kilograms * 16.5 yuan=131 yuan, and 120 yuan every kilogram of adhesives are pressed 0.5 kilogram of calculating for every square, are 60 yuan/square, 30 yuan/square meter of expenses of labour, 221 yuan/square meter of meter.At the bottom of 30 rice bin beams, loose tool is 30 squares * 221 yuan/square meter=6630 yuan.At the bottom of 30 meters of T beams, loose tool is 15 square meter * 221 yuan/square meter=3315 yuan.
The utility model prefabricated case beam, T beam, cored slab production line bed die adopts prefabricate reinforced concrete bed die; be arranged in concrete techniques of bottom die base, element precast finishes again, steel; muscle concrete bed die is transported to new job location and repeats to install and use, and reaches saving fund, shortens and builds beam field time.
First by figure, give the reinforced concrete of reinforced concrete bed die processed, then install thick 6 millimeters, wide 996 millimeters (for 30 rice bin beams), wide to 496 millimeters (for 30 meters of T beams), the positive plain plate of long 3 meters.On positive plain plate, criticize and touch adhesive, paste corrosion resistant plate, construction technology and cost analysis are with reference to content 1.
This prefabricate reinforced concrete die structure design technology and conventional cast-in-situ reinforced concrete bed die construction method economic efficiency contrast are analyzed:
