Problems solved by technology

However, due to the limitations of its material and processing technology, this kind of honeycomb hollow board has very low strength and limited service life within a few years, so it cannot be applied to the field of building construction and formwork in essence.
[0005] Furthermore, at present, for example, the yield strength of a 2.5mm thick stainless steel plate is generally less than 0.235kMPa, which cannot meet the load-bearing strength and 70-year life requirements of ordinary building wall panels or floor slabs

Abstract

The invention provides a high-strength stainless steel hollow composite plate for building construction or template. The composite plate comprises a stainless steel surface plate, a stainless steel bottom plate, a stainless steel honeycomb plate and stainless steel side plates, wherein the stainless steel honeycomb plate is arranged between the stainless steel surface plate and the stainless steel bottom plate, and the stainless steel honeycomb plate is obtained by adopting mold pressing integrated molding; and the stainless steel side plates are arranged between the stainless steel surface plate and the stainless steel bottom plate for edge sealing.

Description

technical field [0001] The invention belongs to the technical field of building construction or formwork of buildings such as buildings, and more specifically relates to a high-strength stainless steel hollow composite plate for building construction or formwork and a manufacturing method thereof. Background technique [0002] At present, the traditional cast-in-place shear wall structure has problems such as heavy on-site workload, waste of building materials, waste of building water, and serious environmental pollution. The vertical connection structure of prefabricated shear walls mostly adopts sleeve grouting connection, steel bar welding connection and indirect lap joint grouting anchor connection. The sleeve grouting connection has problems such as high cost of the sleeve and is not suitable for the use of steel bars with thinner cross-sections; the steel bar welding connection has problems such as heavy on-site welding workload and difficult to guarantee welding quali...
