If these vertical openings are not protected, there will be great safety hazards. If these openings are simply covered with wooden boards without being fixed, the protection may be removed easily, causing safety hazards. In the case of fixed protection, the removal and installation of the protection will be more frequent, resulting in corresponding waste of manpower and materials.

[0006] Preferably, the upper angle steel assembly includes an upper angle steel and a connecting pipe, and the lower angle steel assembly includes a lower angle steel and a threaded sleeve. The upper angle steel and the connecting pipe are fixedly connected, and the length direction of the connecting pipe is vertical. The lower angle steel and the threaded sleeve are fixedly connected, and the connecting pipe and the threaded sleeve are coaxial. The connecting pipe is slidably connected to the screw rod, and the threaded sleeve is threadedly connected to the screw rod.

[0007] Preferably, the upper angle steel includes a horizontal portion of a steel plate and a vertical portion of a steel plate, the plane where the horizontal portion of the steel plate is located is horizontal, the plane where the vertical portion of the steel plate is located is vertical, the horizontal portion of the steel plate and the vertical portion of the steel plate are fixedly connected, the lower end of the horizontal portion of the steel plate is in contact with the upper end surface of the floor main body, and the vertical portion of the steel plate is in contact with the side of the mounting hole.

[0008] Preferably, the inner diameter of the connecting pipe is larger than the outer diameter of the screw.

[0009] Preferably, the cover mechanism also includes a telescopic support strip, a sliding groove is opened on the side of the cover body, the telescopic support strip includes a support strip body and an elastic pad, the support strip body is horizontally slidably connected to the sliding groove, and the lower end of the support strip body is in contact with the upper end of the elastic pad.

[0014] A construction method for a quick-install reusable protective cover plate, using the quick-install reusable protective cover plate, comprises the following steps: Step 1: Fit the upper and lower angle steels to the mounting holes; Step 2: Rotate the screw rod to make the upper angle steel and the lower angle steel clamp the main body of the floor slab; Step 3: Slide and pull the telescopic support strip out of the sliding groove, clamp it, and then fold the cover plate body so that the cover plate body and the telescopic support strip are in contact with the upper end surface of the floor plate body.

[0015] Compared with the prior art, the advantages and positive effects of the present invention are: (1) The cover plate body is rotatably connected to the upper angle steel assembly through a hinge, and the cover plate mechanism is transformed into a clamp-type flap form, so that one side of the cover plate mechanism can be fixed on the floor plate body through the angle steel mechanism.

When a worker accidentally steps on the cover plate body, the support bar body transmits the pressure to a place away from the edge of the installation hole to avoid collapsing the edge of the installation hole, thus playing a safety protection role; (4) The upper end of the lower limit piece is detachably connected to the lower end of the screw rod, and the lower limit piece serves as a safety protection to prevent the lower angle steel from falling off during installation; (5) The elastic buffer is detachably connected to the cover plate body. The elastic buffer plays an elastic role to avoid rigid contact between the cover plate body and the floor plate body, and avoids generating loud noise when in contact.
