Description

Technical Field

[0001] This invention belongs to the field of building technology, specifically relating to a sloping keel support device and formwork. Background Technology

[0002] Currently, the formwork erection method used for sloping concrete components such as sloping panels, sloping beams, and sloping stair slabs is a main joist + triangular wedge timber support system. This means that sloping panels, beams, and stair slabs require inclined formwork for erection. The bottom of the formwork is fixedly connected to the secondary joists, and the top of the scaffold is supported by horizontal main joists. The main and secondary joists are connected by triangular wedge timber for transitional support, thus achieving formwork erection. The load transfer path is as follows: the load of the sloping component is transferred through the formwork to the secondary joists, then distributed from the secondary joists to the main joists via the triangular wedge timber, and finally transferred to the ground foundation through the scaffolding upright system. The main joists are mostly made of φ48.3×3.6mm steel pipes, while the secondary joists are generally made of 40×80mm timber or 40×40×2.5mm square steel. The formwork is usually made of 12-14mm thick plywood, and different angles of triangular wedge timber are used for different sloping angles.

[0003] However, the above-mentioned formwork erection method has the following drawbacks: First, different angled triangular wedges need to be made for inclined components of different angles, resulting in a large amount of timber waste and increasing erection costs. Second, the fixation between the triangular wedges and the secondary and main joists is unstable. Under pressure from above, the triangular wedges may slip, posing a safety risk. Third, the triangular wedges need to be placed one-to-one between the secondary and main joists. When there are many secondary joists, a large number of triangular wedges need to be connected, resulting in low formwork erection efficiency and difficulty in ensuring erection accuracy. This may lead to uneven and ineffective force transmission, creating a safety risk. Summary of the Invention
