Description

Elevator shaft working platform

The invention relates to a working platform, and more particularly to an elevator shaft working platform.

The traditional elevator shaft construction method is to install a safety net under the elevator shaft, and use steel or steel pipe as a support material, and the support material is covered with a template or a solid wooden board as a working platform. After that, the inner wall mold and the outer wall mold are assembled at the edge of the elevator shaft, and the steel bars are arranged between the inner wall mold and the outer wall mold, and then grouted to form a vertical shaft of the elevator.

When assembling the inner wall mold and the outer wall mold, about 20 cm of the group mold and the demoulding space are left around the work table. However, the full-panel wood does not provide the modular and demolished space, or the modular and demolished space must be reserved, which may cause problems due to non-compliance with regulations and excessive open space.

In view of this, there is a need to propose a solution to solve the above problems.

The object of the present invention is to provide an elevator shaft working platform which can be folded up to free enough modular space to facilitate the construction of an elevator vertical well.

In order to achieve the above objective, the elevator shaft working platform of the present invention comprises a first pedal portion, a second pedal portion, a third pedal portion, two first folding portions, two second folding portions, two first hinges, and two The second hinge and the two third hinges. The first pedal portion has a first side, a second side, a third side and a fourth side, wherein the first side is opposite to the third side and is connected to the second side and the fourth side. The second pedal portion has a fifth side, a sixth side, a seventh side and an eighth side, wherein the fifth side is opposite to the seventh side and is connected to the sixth side and the eighth side, and the fifth side is Adjacent to the third side. Each of the first folding portions has a ninth side, a tenth side, a tenth side and a twelfth side, wherein the ninth side is opposite to the tenth side and is connected to the tenth side and the twelfth side . Each of the second folding portions has a thirteenth side, a fourteenth side, a fifteenth side and a sixteenth side, wherein the thirteenth side is opposite to the fifteenth side, and the fourteenth side and the The sixteen sides are connected. The tenth sides of the two first folding portions are respectively connected to the second side and the fourth side of the first step portion by a first hinge, and the first folding portion can be folded to the first by the first hinge On the pedal section. The fourteenth sides of the two second folding portions are respectively connected to the sixth side and the eighth side of the second pedal portion by a second hinge, and the second folding portion can be folded to the second hinge On the two pedals. The eleventh side of the first folded portion is connected to the thirteenth side of the second folded portion by a third hinge.

An elevator shaft working platform according to the present invention, wherein the first folded portion can then be folded to the second fold after the first folded portion is folded over onto the first step portion and the second folded portion is folded over to the second step portion The upper pedal portion is turned over to the second pedal portion.

The working platform of the elevator shaft according to the present invention can be fully laid in the opening of the elevator shaft before the assembly of the template, and it is not necessary to reserve the group mold and the demolishing space like the traditional method, so as to achieve the safe working environment of the elevator shaft without opening, to maintain The safety of the construction workers. When the mold is needed, the folded portion can be folded up to free up enough modular space to facilitate the formation of the elevator vertical well. After the mold is completed, the folded portion can be lowered to cover the remaining space after the template is assembled, and the safe elevator shaft working environment without the falling opening can be reached again. In the future, when the mold is to be demolished, the folded portion is folded again, and the demolished space is vacated. After the template is removed, the folded portion is lowered, that is, it is returned to the state where the elevator shaft is initially fully covered.
