[0002] At present, water towers in many countries use prefabricated water tanks, and prefabricated water tanks are more common due to water seepage and water leakage. Foreign owners and supervisors have proposed that water tower water tanks must be constructed with cast-in-place concrete. The height of the water tower is large. If it is supported by steel pipes with floor-standing full hall fasteners In order to meet the strength and rigidity requirements of the support frame, the distance between the vertical poles near the root of the water tank is too close, and the construction of the scheme is too difficult, and the cost is high and the construction period is long

Embodiment 1
[0025] A water tank aerial cast-in-place method for an inverted conical shell water tower cable-stayed formwork, comprising the following steps:
[0026] (1) Pierce the steel bars 15 on the upper and lower sides of the inner and outer double-ring steel pipe support 1, then lift the inner and outer double-ring steel pipe support 1, and lift it to the top of the reserved vertical steel bar slightly higher than the concrete support tube 5 of the water tower, Align the relationship between the steel bars and the openings of the inner and outer double-ring steel pipe supports 1, pass through the vertical steel bars while falling, and then pour concrete; Control the level of the column end supporting steel beam 9; then install the second joint inner and outer double annular steel pipe support 1 above the column end supporting steel beam 9 in the same way as above, and carry out concrete pouring;
[0027] The inner and outer double annular steel pipe support 1 includes an inner steel...

Disclosed is a water tank cast-in-site method of an inverted conical shell water tower cable-stayed formwork in air. The water tank cast-in-site method of the inverted conical shell water tower cable-stayed formwork in the air includes: firstly, installing internal and external double annular steel tube support seats, and welding a stand column end support steel girder on a connection portion between two segments of the internal and external double annular steel tube support seats; then, welding the bottom of a central stand column on the stand column end support steel girder, and welding a stand column side support between the top of a water tower concrete support cylinder and the central stand column; installing a hydraulic lifting device system, and then hydraulically lifting an inclined truss; next, welding support corbels on the internal and external double annular steel tube support seats, and then dropping the inclined truss on the support corbels, and fixing the support corbels through welding; finally, installing a steel wire rope strand. An installation method of the water tank cast-in-site method of the inverted conical shell water tower cable-stayed formwork in the air is simple to operate, and high in installation efficiency and good in safety due to the fact that the inclined truss is overall lifted through hydraulic pressure.
Description
technical field [0001] The invention belongs to the field of civil engineering, and in particular relates to an aerial cast-in-place method for a water tank with a cable-stayed formwork for an inverted cone shell water tower. Background technique [0002] At present, water towers in many countries use prefabricated water tanks, and prefabricated water tanks are more common due to water seepage and water leakage. Foreign owners and supervisors have proposed that water tower water tanks must be constructed with cast-in-place concrete. The height of the water tower is large. If it is supported by steel pipes with floor-standing full hall fasteners In order to meet the strength and rigidity requirements of the support frame, the spacing between the vertical poles near the root of the water tank is too close, and the construction of the scheme is too difficult, and the cost is high and the construction period is long.
