Embodiment 1

[0041] Such as figure 1 As shown, it is an embodiment of the present invention, a safety protection method for the outer floor passage door of the construction elevator, comprising the following steps:

[0042] S1. Infrastructure construction

[0043] Step 1, set up a vertical scaffold 1 outside the building body, and the vertical overlap of the scaffold 1 is suitable for vertical transportation;

[0044] Step 2, according to the floor spacing of the building body, set up a floor entrance and exit channel platform 2 outside each floor;

[0045] Step 3. Install the outward-opening iron door 3 on the outside of the platform 2 of the floor entrance and exit passage, and install the locking piece outside the outward-opening iron door 3;

[0046] S2. Locking piece installation

[0047] Step 4, outside the elevator 18, an outward-opening iron door 3 is installed. The outward-opening iron door 3 includes two groups of semi-iron doors 4, and the two groups of semi-iron doors 4 move...

Abstract

The invention discloses a safety protection method for an outer floor access door of a construction hoist, and belongs to the technical field of building construction. The safety protection method comprises the steps that firstly, a scaffold is erected, and a floor entrance and exit access platform is erected outside each floor; an outward-opening type iron door is arranged on the outer side of each floor entrance and exit access platform, and a locking piece is arranged outside each outward-opening type iron door; an outward-opening type iron door is arranged outside the hoist, the outward-opening type iron door comprises two sets of half iron doors, first inductors and induction plates are arranged at the upper ends of the two sets of half iron doors, and the induction ends of the first inductors face the induction plates; an electric push rod is arranged on one set of half iron door, and the output end of the electric push rod moves towards the other set of half iron door; an adsorption group and a second power supply are arranged on the other set of half iron door, and a limiting column is arranged at the output end of the adsorption group; a connecting groove is formed in a limiting block, and the bottom end of the limiting column is matched with the connecting groove; and the second power supply is suitable for supplying power to the adsorption group. The problems that the outward-opening type iron door cannot be conveniently closed and cannot be effectively closed and locked are solved.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a safety protection method for an outer floor passage door of a construction elevator. Background technique [0002] After the concrete structure construction of high-rise building projects is completed, elevators are generally used to complete the transportation of basic materials or manpower. Floor access platforms are set between floors and elevators, and outward-opening iron doors are installed to make it convenient for people to enter and exit; [0003] When using the outward-opening iron door outside the floor entrance and exit passage platform, the operator will actively close the outward-opening iron door to ensure the safety of the edge of the floor entrance and exit passage platform, but there is uncertainty due to artificial closure. It is easy to cause forgetting or man-made damage, which makes the outward-opening iron door unsafe and increas...
