Description

Technical Field

[0001] The utility model belongs to the technical field of installation of household weak-current boxes, in particular to a standardized inner support of a household weak-current box. Background Art

[0002] The traditional method of pre-installing weak-current boxes is to reserve holes and then install the boxes. This method can easily cause dimensional deviations and displacements in the pre-buried holes. The secondary piping operation space is limited, making construction extremely difficult and the quality of pipe connections difficult to guarantee. Therefore, most of the weak-current phases currently entering households are pre-installed. Before pouring concrete, the boxes are fixed in place at the installation location, and then the walls are poured. The pre-installed method can ensure that the boxes are well embedded in the concrete walls, avoiding the need to fill, repair and plaster the gaps around the boxes later.

[0003] At present, most household weak-current boxes are installed in a pre-buried manner. During the installation process, since the box is hollow and has a weak pressure-bearing capacity, the box may be compressed and deformed after concrete pouring, resulting in the inability to install the box core and cover after the box is installed. Therefore, a standardized internal support for the household weak-current box is required. The inner wall of the box can be supported by a supporting structure to prevent the box from being deformed by the squeezing of concrete, thereby increasing the installation efficiency of the household weak-current box.
