AI Technical Summary
When the concrete on the inner wall of the water tank in the inverted conical water tower is constructed, the existing formworkless construction method makes it difficult to vibrate the concrete and prone to "falling" phenomena, resulting in a deviation in the thickness of the cone inclined wall, poor density, poor appearance quality and waterproofing effect.
The construction structure of the inner mold is adopted with the embedded anchor rod supporting the inner mold. The inner mold has good stability and can be fully vibrated during the pouring process of concrete, with high density to avoid "falling".
By supporting the inner mold with embedded anchor rods, the concrete is fully vibrated and high density, avoiding the "fall" phenomenon, and improving the construction quality of the cone under the water tank.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building construction, in particular to a lower cone construction structure of a water tank in an inverted cone-shaped water tower. Background Art
[0002] At present, a common construction method for the inner wall concrete construction of the water tank in the inverted cone water tower is concrete pouring without formwork. This method requires adjusting the slump of concrete, reducing the slump of concrete, adding early strength agent, and improving the self-plasticity of concrete. This construction method makes it difficult to vibrate the concrete. In the absence of formwork, the concrete vibration is very likely to "fall", causing the thickness of the inclined wall of the cone to deviate. Due to insufficient concrete vibration, the density of the inclined wall concrete is poor, the appearance quality is poor, and the waterproof effect is poor. Utility Model Content

Here, the schematic implementation mode of the utility model and its description are used to explain the utility model, but are not used as a limitation of the utility model.
[0016] See also Figure 1-Figure 3 The utility model provides a construction structure of the lower cone of a water tank in an inverted conical water tower, comprising a lower ring beam 1 of the water tank cone, a full frame 4 is erected on the periphery of the lower ring beam 1 of the water tank cone, and a bottom formwork 5 of the lower cone of the water tank is laid on the full frame 4; a cushion layer 6 is cast on the bottom formwork 5, and a plurality of rows of anchor rods 7 are pre-buried in the cushion layer 6 along the generatrix direction of the lower cone 3 of the water tank, and the lower cone steel bars of the water tank are tied on the cushion layer 6, and the lower cone steel bars of the water tank are tied and fixed to the anchor rods 7; an inner mold 8 is penetrated on the anchor rods 7 and located on the outside of the lower cone steel bars of the water tank, and a gasket is arranged between the inner side of the inner mold 8 and the lower cone steel bars of the water tank to control the thickness of the protective layer; a wooden slat 9 is penetrated on the same row of anchor rods 7 and located on the outside of the inner mold 8, and a nut 10 is arranged on the anchor rod 7 to lock the wooden slat 9.
[0017] During implementation, concrete pads 2 can be set at the lower part of the lower ring beam 1 of the water tank cone; the concrete pads 2 are arranged in a circle with a spacing of 500mm. The concrete pads 2 are set to facilitate the threading of ropes after the prefabrication of the water tank cone is completed for overall lifting. The cushion layer 6 is made of light aggregate concrete with a thickness of about 50mm; the bottom of the bottom mold 5 is against the outer side of the lower ring beam 1 of the water tank cone, and the bottom of the inner mold 8 is against the top surface of the lower ring beam 1 of the water tank cone; an external frame is set up outside the full frame 4 for auxiliary construction.
[0018] A tie rod 11 is arranged between two adjacent wooden slats 9 at the same height, so as to reinforce the wooden slats 9 at the same height in series; the tie rods 11 can be arranged in an up-and-down staggered manner.
