Profiled steel sheet composite board as well as roofing board, floor board or wall panel with composite boards

Abstract

The invention relates to a profiled steel sheet composite board as well as a roofing board, a floor board or a wall panel with the composite boards. The profiled steel sheet composite board comprises a profiled steel sheet and a filler, wherein the profiled steel sheet is a ribbed plate; the profiled steel sheet serves as the force-bearing main body of the composite board; a cavity at the lower part of the profiled steel sheet is filled by the filler; an auxiliary steel material is welded on one side or the bottom of the vertical plate rib; a steel wire mesh piece is attached and welded on the lower open surface of the profiled steel sheet; the profiled steel sheet at the closed surface of the profiled steel sheet is used for resisting pressure, while the auxiliary steel material is used for bearing tension, and the two components work cooperatively by use of the plate rib to resist the bending moment. The composite board is low in weight and high in strength; under the same span and load, the dead weight of the composite board is about 1/5 of that of the traditional profiled steel sheet concrete floor board, and therefore, product support is provided for the realization of a large-span beamless space.

Description

technical field [0001] The invention relates to the field of housing engineering, in particular to a novel profiled steel composite panel suitable for roof panels, floor panels and wall panels. Background technique [0002] The building structure of a house is a very "selfish" structure, and a large part of its carrying capacity is used to bear its own weight. The strength-to-weight ratio (the ratio of carrying capacity to its own weight) is an extremely important indicator for measuring building materials and building products. Especially for slab-type spanning flexural members, the strength-to-weight ratio is a key factor. In addition, in seismic design, the greater the self-weight, the greater the earthquake action. Self-weight is one of the decisive factors in structure and foundation design. At the same time, housing construction is affected by its functional requirements, and building materials and products are also required to have functions such as environmental prot...

Problems solved by technology

[0003] At present, the light-weight panels at home and abroad are mainly color steel composite panels. The disadvantage is that in order to achieve a certain span, it must be used with steel purlins. The construction process is complicated, and the durability, water resistance, fire resistance, and airtightness are poor. In particular, color steel composite panels cannot be used as floor slabs, and some lightweight concrete slabs have also appeared in the domestic market, but the strength-to-weight ratio is poor and the manufacturing process is relatively complicated, so the application is limited, especially basically cannot be used as a certain span The use of floor slabs
