The template fastener has a simple structure and is easy to install. Workers using square column fasteners can reinforce the column formwork within 20 minutes. Once launched, it was welcomed by most construction workers. Let me give you a detailed introduction to template fasteners.
1. Formwork fastener is a new type of fastener used to construct square columns in building construction. It is suitable for the quick reinforcement of the square column after the custom square column template and the ordinary template template. Its novel structure and installation method are obviously different from traditional frame pipe and channel steel reinforcement.
2. Formwork fastener is a specially customized supporting fixture for fixing square column formwork. Its appearance consists of a galvanized card plate corresponding to four elbows. One end of the card board is arranged in a curved structure, and each card board is provided with a plurality of fixing holes with equal intervals along the length direction. The wedge-shaped fixing pin passes through the through hole and the fixing hole to fix the limit sleeve and the clamping plate to form a square column template fastener that is convenient for installation and disassembly.
3. Formwork fasteners are more practical than traditional reinforcement methods. The size can be adjusted according to different specifications of columns, and it is suitable for reinforcement of different specifications and sizes. A set of multi-purpose, the material is more wear-resistant, easy to store, to achieve the ideal state of greatly increasing the turnover times and reducing the cost of building materials.
The template fastener is scientific and reasonable, the structure is simple, the installation and disassembly are convenient, and it is easier to keep after disassembly.
There are many types of materials for making stainless steel screws, and they can be divided into several categories according to the structure at room temperature: austenitic type: such as 304, 321, 316, 310, etc.; martensite or ferrite type: such as 430, 420, 410 Wait; Austenite is non-magnetic or weakly magnetic, while martensite or ferrite is magnetic. Due to component segregation or improper heat treatment during smelting, a small amount of martensite or ferrite in austenitic 304 stainless steel will result. In this way, 304 stainless steel will have weak magnetic properties. After 304 stainless steel is cold worked, the structure will also be transformed into martensite. The greater the degree of cold working deformation, the more martensite transformation and the greater the magnetic properties of the steel. Like a batch of steel belts, Φ76 tubes are produced without obvious magnetic induction, and Φ9.5 tubes are produced. Because the bending deformation...
