Bracket[1]The word "Scaffold" is translated from the English word "Scaffold", which is originally a term in the construction industry. It specifically refers to the temporary support set up when building a building. This support will be removed as the building is completed.But nowadays, stents are widely used and can be found everywhere in work and life, such as tripods for cameras, heart stents used in the medical field, etc.
3. Application in life: notebook support, air conditioning support, pipe support, etc.
4. Application in production activities: greenhouse and greenhouse support, etc.
According to the stress position of the support
1. Overall[2]Stressed support: the vertical pole and the horizontal pole are connected to form a whole frame through a wheel, a bowl buckle or a fastener. When the load and internal force of the vertical pole are transmitted downward, the horizontal pole connected to it can play the role of distributing the load and bear the load together with the vertical pole.
2. Single row of axially stressed supports: since there are few horizontal connections between single row supports, the construction load is mainly transmitted from top to bottom along single row supports.The adjacent supports do not affect each other, and each row of supports plays the role of supporting load separately.
3. Simply supported flexural support: the support erected during construction of some door openings or river crossings is usually relatively large in span, and the construction load is uniformly distributed on the cross beam of the support, so that the cross beam will have a certain deflection and deformation, thus playing the role of bearing the load.
Cardiac stent

yesInterventional cardiac surgeryIt is a commonly used medical device for dredging arteries and blood vessels.The main materials are stainless steelNiTi alloyOr cobalt chromium alloy.It first appeared in the 1980s and has experienced the development of metal stent, coated stent and soluble stent.
hydraulic support

edit
hydraulic support It is a structure used to control the underground pressure of coal mining face.The external load of mining pressure acts on the hydraulic support.In the mechanical system of the interaction between the hydraulic support and the surrounding rock of the mining face, if the resultant force of each support part of the hydraulic support is exactly the same line as the resultant force of the external load acting on the hydraulic support by the roof, the hydraulic support is very suitable for the surrounding rock of the mining face.

PV bracket isSolar photovoltaic power generation systemIn order to place, install and fix the solar panel, a special support is designed.General materials include aluminum alloy, steel structure and stainless steel.PV support products include ground support system, plane roof support system, adjustable angle roof support system, inclined roof support system, column support system, etc.
Camera bracket

edit
If the camera is only fixed to monitor a certain position and does not need to rotate, only the camera bracket can meet the requirements.Common camera brackets are simple to install, inexpensive, and of various types.Common supports are short, long, straight and curved, and different models are selected according to different requirements.The outdoor support mainly considers whether the load capacity meets the requirements, and then the installation position. Because many outdoor cameras in different occasions have special installation positions, some are installed on poles, some are installed on tower cranes, and some are installed on iron frames... For various reasons, the existing support may be difficult to meet the requirements, and need to be processed or improved,I won't say more here.
