Background technique

In the prior art, in places such as Hong Kong and Singapore, large-scale iron formwork is often used for construction. Large-scale iron formwork usually uses steel plates with a thickness of 4mm as the panels, and uses angle iron, channel steel and other profiles as the skeleton to bear the force, and is combined and welded into a After being integrated, it becomes a formwork with a relatively large size, which is used for the construction of cast-in-place concrete for the structure of the floor or non-structural walls. Compared with aluminum formwork and wood formwork, the use of iron formwork has obvious advantages in that it can greatly increase the construction speed and significantly improve the quality of cast-in-place concrete, thereby saving construction costs.

When using iron formwork for construction, because iron formwork needs to be installed on the exterior wall of the building, it is required to be equipped with a working platform for supporting the iron formwork and providing access for construction personnel. Usually, the working platform is also welded and combined with steel plates, angle irons, channel steel, I-beams and other profiles. Usually the working platform is hung on the exterior wall facade during building construction by screws or other connection forms. Cooperate with the supporting iron formwork to pour the concrete of the wall body, at the same time, it can provide the working position for the workers to operate the iron formwork, and at the same time provide safety guarantee for the workers to operate.

Generally speaking, the workbench is usually designed with two floors, the upper floor is used to support the iron formwork and the construction floor, and the lower floor is used to repair the connection position between the construction formwork and the concrete wall. In special cases, the workbench can also be designed with three or four floors according to the construction requirements.

During the construction of iron formwork, the floor of the first floor is usually divided into left and right parts, one part is constructed first, and the other part is carried out later. For example, when the left part is pouring the concrete wall, the right part is used for the construction of the next floor. After the construction of the left part of the wall is completed, the large iron formwork used in the left part of the wall is transported to the right part by tower crane, and the construction of the right part of the wall is carried out. The process of lifting the formwork is called flying formwork. At the same time, due to factors such as the shape of the building, some formwork is not suitable for flying to another part. This part of the formwork is called the registration board. Generally speaking, the registration board will be placed on the ground with a tower crane for storage, and it will be used in construction. , then hoist it from the ground to the floor for use.

Therefore, existing this workbench and construction method need take larger ground space to store formwork, especially difficult solution for the less high-rise construction site of construction site, and formwork will use tower crane to lift up and down repeatedly, It needs to take up a lot of time for the tower crane, which is not only labor-intensive and time-consuming, but also increases the construction cost.
