Background
In construction, some concrete structures such as floor slabs are reserved with reserved holes which are reserved for construction, sometimes called manholes, and construction workers can perform construction operations through the reserved holes.
When these preformed holes are not used by constructors, the constructors need to block the preformed holes, so that the constructors are prevented from falling from the preformed holes in the construction process, and the basic requirements of construction safety specifications are met.
In order to operate conveniently in the actual work progress, constructors generally adopt a apron to directly cover and establish on the preformed hole, and when needing to use the preformed hole, constructors take off the apron from the preformed hole again.
The direct covering mode for covering the prepared hole has the following defects:
firstly, a constructor is inconvenient to fix a cover plate covered on a preformed hole, so that the cover plate can slide, and the preformed hole has potential safety hazard of untight plugging;
secondly, later stage constructor need pour the concrete in the preformed hole to make whole floor structure complete, and constructor only adopts the apron to cover the preformed hole and establishes the shutoff, and the apron can not provide support for follow-up concreting, thereby causes the wasting of resources to a certain extent.
