Description

Technical Field

[0001] This utility model relates to elevator metal components, and more particularly to an elevator metal component. Background Technology

[0002] 1. Example 1: Chinese Patent Publication No. CN203497899U discloses a composite door panel for elevators, comprising a door panel face, a filling layer, a rear sealing plate, and a door panel end cap. The filling layer is located between the door panel face and the rear sealing plate, and is bonded to both the door panel face and the rear sealing plate. The door panel end cap is fixed to one side of the door panel face and the filling layer. The filling layer is filled with a lightweight composite material.

[0003] The above-mentioned methods of increasing the thickness of the filler layer and covering the filler layer with a rear sealing plate do not solve the problem of the structural strength of the door panel itself. The overall structural reinforcement through the rear sealing plate results in an excessively thick and complex structure, requiring more materials and resulting in low production efficiency.

[0004] 2. Currently, in the field of elevator technology, elevator wall panels are mostly made of single-layer stainless steel plates. Then, iron or steel frames are welded or fixed to the back of the stainless steel plates as reinforcing ribs to increase strength, but the problem of the structural strength of the stainless steel plates themselves has not been solved. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an elevator metal component with a reasonable structural design that can achieve the required strength without the need for fixed reinforcing ribs on the back, thereby reducing the number of parts and the complexity of the structure.

[0006] The solution to the above technical problem is as follows: An elevator metal component includes a stainless steel plate, a high-temperature hot melt adhesive layer, a zinc metal upper layer, an iron plate layer, and a zinc metal lower layer; the iron plate layer is wrapped between the zinc metal upper layer and the zinc metal lower layer. Stainless steel plate, high-temperature hot melt adhesive layer, zinc metal upper layer, iron plate layer, and zinc metal lower layer are sequentially connected and fixed to form elevator metal components; the zinc metal upper layer and zinc metal lower layer are plated on the upper and lower surfaces of the iron plate layer. The thickness of the stainless steel plate is 0.15mm to 0.6mm; the thickness of the high-temperature hot melt adhesive layer is 0.05mm to 0.2mm; and the total thickness of the upper zinc metal layer, the iron plate layer, and the lower zinc metal layer is 1.4mm to 2.0mm.

[0007] The amount of zinc metal used on the surface of the iron plate layer is 80 g / m² to 120 g / m².

[0008] The thickness of the upper and lower zinc metal layers is 6.0 micrometers to 8.5 micrometers, and the remainder is the thickness of the iron plate layer.

[0009] The adhesive material of the high-temperature hot melt adhesive layer is PET polymer adhesive film hot melt adhesive.

[0010] The advantages of this utility model for an elevator metal component are as follows: This product achieves the required strength without the need for a fixed reinforcing rib on the back, reducing the number of parts, simplifying the structure, improving production efficiency, and resulting in a simpler structure. From a mechanical performance perspective, this product achieves a bending stiffness ≥15kN / mm² (measured value) through the direct composite of 0.15mm~0.6mm thin stainless steel sheet and 1.4mm~2.0mm double-sided galvanized stainless steel sheet, which is more than 40% higher than traditional single-layer stainless steel door panels. In terms of process cost innovation, eliminating the traditional reinforcing rib welding process reduces three production steps, lowering manufacturing costs by 30%. It also avoids surface finishing work caused by welding heat deformation, maintaining the integrity of the stainless steel surface decoration and preventing rust at the weld points of the reinforcing ribs. The lightweight and noise reduction are combined; the composite interface damping effect can reduce elevator operating noise by 3-5dB(A). The ribless bimetallic composite design reduces the number of parts and simplifies assembly. This product has passed the salt spray test for over 1000 hours (GB / T10125-2021), meeting the requirements for use in high-humidity coastal environments. Its fire resistance meets the GB / T2408-2008 Class A standard. The integrated corrosion-resistant composite design eliminates the need for a painting process, reducing costs by 30%. It also exhibits excellent bending and deformation properties; the double-sided galvanized stainless steel sheet has good bending and elongation properties, and bending will not damage the stainless steel sheet.

This product achieves a breakthrough in mechanical performance: through the direct composite of 0.15mm~0.6mm thin stainless steel sheet and 1.4mm~2.0mm double-sided galvanized stainless steel sheet, a bending stiffness of ≥15kN / mm² (measured value) is achieved, which is more than 40% higher than that of traditional single-layer stainless steel door panels. In terms of process cost innovation, eliminating the traditional reinforcing rib welding process reduces three production steps, lowering manufacturing costs by 30%; it also avoids surface finishing work caused by welding heat deformation, maintaining the integrity of the stainless steel surface decoration, and preventing rust at the weld points of the reinforcing ribs. Lightweight design and noise reduction work together; the composite interface damping effect can reduce elevator operating noise by 3-5dB(A). The ribless bimetallic composite design reduces the number of parts and simplifies assembly. This product has passed the salt spray test for over 1000 hours (GB / T10125-2021), meeting the requirements for use in high-humidity coastal environments, and its fire resistance meets the GB / T2408-2008 Class A standard.

This thickness is suitable for large passenger elevators with a load capacity of 2000 kg to 3000 kg. The large internal volume of the elevator car and the wide plate make the inner wall panel of the elevator car stronger, increase the weight of the elevator car, and improve the stability of operation.

This thickness is suitable for medium-sized passenger elevators with a load capacity of 1000 kg to 2000 kg, suitable for most buildings.
