abstract:
The utility model relates to a multi-modal nozzle screw, which is used for connecting and fixing vertical formwork engineering in building construction. It consists of two small nozzles, two outer rods and an inner rod. The outer rod and the inner rod are connected through a connecting pipe, the threads at both ends of the inner rod are connected with the internal thread holes of the connecting pipe in a threaded way, and the internal thread of the outer rod is connected with the external thread holes of the connecting pipe in a threaded way to form a complete set of screws. When dismantling the formwork, it is not necessary to burn screws, and the outer rod is separated from the connecting pipe with a wrench, so the formwork is easy to fall off. In order to meet the needs of engineering and the choice of operators, the design of connecting pipes is diversified, including circular connecting pipes, semi-circular connecting pipes and square connecting pipes. It not only saves labor and is convenient to operate, but also eliminates all common quality problems of old traditional screws. Solve the big problems of huge screw combustion and environmental pollution; Its successful development ensures the progress and quality of construction projects, thus eliminating the old traditional screws.
Main propositions:
It is characterized in that it is divided into three sections and consists of fittings such as a connecting pipe (1), an outer rod (2), an inner rod (3) and the like. The outer rod (2) and the inner rod (3) are connected through a connecting pipe (1), and the threads at both ends of the inner rod (3) are connected with the connecting pipe. A complete set of screw is formed, and the nozzle (1) is designed in various styles. The outer rod (2) is divided into a conical rod and a round straight rod, the inner rod is a smooth round rod and a threaded rod, and the gasket (5) between the nozzle (1) and the cushion block (6) is divided into two kinds of Fiona Fang.
