In order to further protect the safety of the construction workers, the utility model also includes several protective railings, one end of which is close to the fixed column or the auxiliary column, and the other end extends to the outside of the construction structure. With such a structural design, all open doors on both sides Corresponding protective railings are provided to strengthen the protection of the life safety of construction workers when they enter and exit.

For the convenience of fixing the main column and the auxiliary column on the construction structure smoothly, the bottom of the fixed column, the top of the adjustable column and the bottom of the auxiliary column are all equipped with a fixed foot plate, and the fixed area can be increased at the same time. Enhance the stability of the entire mast.

Further, the auxiliary beam is fixed to the main beam by bolts, and the main beam is connected to the fixed column by bolts. Such a structural design facilitates disassembly and assembly.

In order to facilitate construction and open the open door leaf to facilitate the construction personnel's operation, the open door leaf has two leaves, which are respectively connected with the fixed column and the auxiliary column through hinges.

Further, the fixed column and the adjustable column can be connected by bolts or pins. At this point, the adjustable column can be moved up and down along the fixed column according to the actual height, and then fixed with bolts or pins. It is easy to operate and easy to use. flexible.

Preferably, the fixed column, the adjustable column, the auxiliary column, the auxiliary beam and the main beam are all made of square steel pipes, which is conducive to improving the load-bearing and stability of the entire gantry.

Beneficial effects: the utility model is suitable for the floor construction of most frame structures. The main column in the utility model can be adjusted according to the actual height of the actual building floor, with strong adaptability and flexible use; at the same time, the middle column unit, the main beam and Parts such as the open-type door leaf adopt standardized design, which can improve the turnover rate of the utility model.

Detailed ways

The technical solutions of the utility model are described in detail below, but the protection scope of the utility model is not limited to the embodiments.

As shown in Figures 1 and 2, a protective door frame for a turnaround standardized construction elevator floor of the present utility model includes two vertically arranged main columns 1 and a main beam 2 transversely connected between the two main columns 1 , the middle position below the main beam 2 is vertically provided with an intermediate column unit 3, and an open door leaf 4 is respectively installed between the intermediate column unit 3 and the main column 1; wherein, the main column 1 includes a fixed column 11 and an adjustable column 12, The adjustable column 12 is inserted and fixed on the top of the fixed column 11 and can be moved up and down along the height direction of the fixed column 11; The sub-beams 32 at the upper and lower ends are welded with steel mesh sheets 33 inside the rectangular frame formed by the sub-columns 31 and the sub-beams 32 , and the top of the sub-columns 31 is fixedly connected with the main beam 2 .

Wherein, the fixed column 11 and the adjustable column 12 may be connected by bolts or bolts.

This embodiment also includes several protective railings 5, one end of the protective railing 5 is close to the fixed column 11 or the secondary column 31, and the other end extends to the outside of the construction structure.

Wherein, the bottom end of above-mentioned fixed column 11, the top end of adjustable column 12 and the bottom end of secondary column 31 are all equipped with fixed foot plate 6; Between secondary beam 32 and main beam 2 are fixed by bolts, and main beam 2 is fixed with bolts. Column 11 is connected.

There are two openable door leaves 4 in this embodiment, and they are respectively connected to the fixed column 11 and the auxiliary column 31 through hinges.
