The construction screw is a novel building material tool that serves as a support for stress transfer and adjustment during the overall lifting of a building. It comprises: support rods, reinforcing bars, and a support plate surface. The support rods are fixed underneath the support plate surface, while the reinforcing bars are securely connected to the support rods. Adjusting screws are installed at the lower ends of the support rods. A grooved sliding base is positioned on the upper surface of the support plate, within which a sliding disk is placed. An adjusting screw is located on one side, with its end pressing against the sliding disk, allowing the sliding disk to move via the action of the screw. This design ensures smooth and reliable stress transfer through the support plate and facilitates easy adjustment of positional offsets during the lifting of the building.
The upper and lower brackets mentioned by construction screw manufacturers typically refer to the parts used for supporting beam and plate formwork in adjustable-height top supports and scaffolding, which are used in conjunction with cup-lock scaffolding to serve as the upper top support and lower bracket, respectively. These parts are known by different names in different regions, also referred to as U-shaped supports, oil supports, or screws, with the standardized term being adjustable base top supports. Their specifications usually range from φ26 to φ34. The screws are generally processed from round steel on a thread rolling machine, with a U-shaped steel plate welded on top as the top support and a flat steel plate welded on the bottom as the bottom support. The screw nuts are made of cast iron.
