Construction of the arch stand aside should consider several factors
Building templates production have been related to the safe use, building templates and bracket member after entering the required product acceptance, after the relevant standards can be used. Building templates and embedded parts, holes for design and technology required to meet the requirements of the bracket when building templates reserve of construction arch, should consider the following factors:

(1) support (arch) frame to withstand the full elastic deformation Loads.
(2) Flexible because static live load and impact load generated by deformation.
(3) to load because of inelastic deformation member joint produced by extrusion.
(4) non-elastic deformation due to foundation settlement arising.
