What are the characteristics of building fasteners? Building fasteners are a component of construction machinery. The steel pipe fastener is an intermediate connecting part connecting the guide rail and the slippers. The guide rail is fixed on the guide rail pillowcase and has the function of maintaining the gauge and preventing the guide rail from moving vertically and horizontally relative to the guide rail pillowcase.

On the track of the concrete slipper, the elasticity of the concrete slipper is very weak, so the fastener provides sufficient elasticity. Many builders don't know much about the characteristics of building fasteners, but apart from knowing that building fasteners are an indispensable part, they don't know what characteristics they have. Let me introduce the characteristics of building fasteners.

Building fastener is an important part of ensuring the safety of construction machinery and protecting the safety of personnel and equipment. Its low cost, large role, is an indispensable part of the construction project. Building fasteners have different characteristics in different models, and the tensile strength also has its own advantages. If the use conditions are different, other types of construction fasteners can be selected to ensure efficiency.

What are the characteristics of building fasteners?

1. construction fasteners have the function of ensuring safety. In the case of side-slip of construction equipment, they can effectively pull the equipment to the normal position. They have anti-skid function to ensure that the steel pipe and construction fasteners are consistent with the state and prevent the steel pipe from slipping. In the maintenance of building fasteners, the entire building fasteners are galvanized and passivated dual anti-rust treatment, which has strong anti-rust ability and long service life. Therefore, there will be no corrosion and damage to the current, maintenance after construction is also very convenient, and maintenance costs are greatly reduced.

Building fasteners generally refer to the intermediate connecting parts connecting two parts, which are often used to fix steel pipe supports with an outer diameter of 48mm in construction. Fasteners are divided into right-angle fasteners (cross fasteners and directional fasteners), rotary fasteners (movable fasteners and universal fasteners), butt fasteners (straight fasteners and direct fasteners), etc.

The production method of the fastener includes the production method of the cover and the intermediate hot pressing process. The production method of the cover is as follows: the steel plate is pressed into a blank and then the blank is heated, the shape of the cover is pierced by a punch, the workpiece enters the punch to drill bolt holes after cooling, the workpiece is placed on the shotcrete machine, and the outer sides of the opening hole are respectively protruded and formed.

The production method of the middle part is that after the steel plate passes through the stamping blank, a long hole is drilled at the cross-shaped longitudinal installation bolt position, the workpiece is heated, and the shape of the middle part is stamped according to the mold. After cooling, place the workpiece on an inclined table and refine each hole to shape. An advantage of the present invention is that the method of production of the fastener is a hot stamping process. The process is to improve the toughness of fasteners, not easy to deformation, fasteners after hot stamping to increase the R arc, increase the bayonet joint surface area, increase the contact area, increase friction, so that the building fasteners more secure and stable.
