No matter what the product is, the problem will affect the use, Baotou EPS The surface of the decorative line is cracked, the internal steel is corroded, and the corrosion leaks out; Manufactured when not installed EPS Honeycomb, pit surface and leakage rib of components will rust; EPS decorative line has been installed. If the top explosive screw is used to fix it, the top explosive screw will rust; If the embedded reinforcement is welded, the welded parts will rust without rust prevention treatment. If the parts are connected to the main body due to rust, and the parts fall, it will cause serious safety problems.
The safety problems of installing EPS decorative molding are: due to the corrosion of reinforcement, the solidity of components is damaged; The screw holes of EPS decorative lines are not standard and easy to fall off; There are no uniform rules and methods for the length of the top burst screw fixed on the main structure.
The top explosion screw has no rust prevention measures; There are no rust prevention measures for the welded joints of steel welded connections. The part has low local strength and poor durability. Due to the spraying method, the spray gun is blocked or the blade is damaged, and only glass fiber or mortar is sprayed. The pre mixing method will result in uneven mixing and misplaced glass fibers. Regular inspection shall be carried out during production and operation.
Since EPS decorative lines are thin-walled components, "dry wear" or "wet wear" is easier than thick components (such as concrete components), and the degree of dry and wet deformation is also greater. If it is constrained by rigidity, it will not release dry and wet deformation, which will produce a large internal force, so it is easy to pull the surface of the board. Special attention shall be paid to avoid or reduce the strict restrictions in EPS decorative line design.
The glass fiber used in EPS decorative line will be corroded by alkali in cement stone for a long time, which will greatly reduce the tensile strength and bending strength of EPS decorative line. Therefore, when designing EPS decorative lines, the 28d aging strength cannot be used as the calculation basis, but the aging attenuation strength needs to be used as the computer basis.
