Pouring Hollow Core Concrete. This system consists of an outer steel formwork, an H-shaped steel piece acting as the outer formwork and weight-bearing component for tensioning the prestressed steel wires. It is assembled by inserting the steel wires into a wedge-shaped slot for cutting the wires and drilling holes for inserting steel pipes, resulting in a hollow core precast prestressed concrete wall panel. The inner steel formwork is a T-shaped steel piece placed horizontally, perpendicular to the panel manufacturing platform. Pre-fabricated angle iron is used to secure the corners, forming a rectangular frame with a smooth, level inner concrete edge along the formwork. The manufacturing process of precast prestressed concrete wall panels using the 2-axis steel wire tensioning system before pouring hollow core concrete involves prestressing the steel wires around the panel in both axes. A steel pipe is inserted into the center of the precast concrete panel and pulled out as the concrete begins to harden, resulting in a hollow core precast concrete wall panel. The method for installing precast prestressed concrete wall panels using a 2-core hollow core steel wire tensioning system involves installing the precast wall panels on concrete ground beams. Construction steel is embedded in the concrete ground beams. The hollow core precast wall panels are installed by inserting all construction steel bars into the hollow core. Liquid concrete is poured into the hollow core of the panel. Construction steel is threaded through the steel loops on the sides of the panel to secure the panel joints. Liquid concrete is then poured to seal the joints. Threaded couplers are used to connect the construction steel bars, ensuring a continuous connection throughout the building. This installation method ensures that the precast concrete wall panels are interconnected with construction steel from the bottom to the top floor, resulting in a strong reinforced concrete structure for the entire building. ------03/04/2020------(OCR) Page 1 of 1.

On the side of the H-shaped steel (H), the size is larger than the steel wire for pulling (4) at the position specified by the engineer. It has special characteristics, namely, it is a steel in the shape of an H (H) placed horizontally, with the central axis of the steel in the shape of an H (H) acting as a load-bearing device for the 2-axis steel wire tensioning. The drilling of a circular hole (6) on the side of the steel in the shape of an H (H) serves as a channel for cutting the steel wire for tensioning (4) and as a channel for checking the correct stretching distance of the steel wire for tensioning (4) according to engineering principles before cutting the steel wire. One end of the steel is wedge-shaped (1 0) and the other end has a wedge-shaped channel (11), allowing the two steels to pass through and be joined together in a wedge-like manner, to serve to allow the outer steel formwork to stretch between each other and assemble at a right angle according to the specified design. The drilling of a circular hole (12) on the side of the steel in the shape of an H (H) and welding of a steel pipe in the transverse direction are used as a channel for pulling the steel pipe with the tensioning lugs (1 3) in the production of the wall panel, which makes the wall panel 2.

The special characteristic is that the steel pipe with steel lugs (13) is pulled out of the precast concrete wall panel to create a hollow space in the precast concrete wall panel. This is done by pulling while the concrete is beginning to harden with a motor puller (19). Then leave the time for the concrete to harden to the strength according to the engineering calculations, then cut the steel wire for pulling (4), causing the concrete to be compressed.
