Background Art
[0002] The traditional shear wall direct buried distribution box bottom shell pre-buried installation method uses a wooden formwork support structure to reserve a hole during construction. After the shear wall construction is completed, the wooden formwork support structure is removed, the reserved hole is polished regularly, the distribution box body is installed, and the reserved hole gap is repaired. The traditional construction method has the disadvantages of secondary finishing and cracking of the wall at the edge of the box shell, which wastes a lot of manpower and materials. Although the construction method of pre-buried the box body with the main structure can effectively avoid the above problems, in the construction process of super high-rise buildings, the shear wall is relatively thick and large. Affected by the large amount of concrete pouring, the construction load generated during concrete pouring and vibration, the strength of the box body itself cannot withstand it, and it is very easy to have quality defects such as leakage inside the box shell, deviation of the box shell, displacement, and deformation.

[0005] The supporting assembly includes a cross bracket, a vertical supporting rod, a horizontal supporting rod and an internal supporting rod. The cross bracket is in a cross shape and includes a horizontal section and a vertical section. The interior of the cross bracket is a hollow structure and a thread is arranged on the inner wall. The vertical supporting rod and the horizontal supporting rod are screw structures. The two vertical supporting rods are symmetrically installed one above and one below at both ends of the vertical section of the cross bracket, and the two horizontal supporting rods are symmetrically installed at both ends of the horizontal section of the cross bracket.

[0006] The distal ends of the vertical support rod and the horizontal support rod are both provided with hexagonal columns, so as to facilitate the use of a wrench to rotate the support rod.
[0007] The support assembly also includes a support plate, which is a hollow truncated cone structure made of stainless steel; the height of the cone is h < 2 cm; the upper bottom surface of the support plate is welded and fixed to the vertical support rod, the horizontal support rod and the end of the internal support rod, and the lower bottom surface of the support plate is in contact with the inner wall of the box; when the support rod supports the inner wall of the box, it is supported by the lower bottom surface of the truncated cone to increase the support area.
