One-truss steel bar floor support plate with disassembly-free bottom form

Abstract

The invention discloses a one-truss steel bar floor support plate with a disassembly-free bottom form. The one-truss steel bar floor support plate is characterized by being formed by combining the disassembly-free bottom form, capital-omega-shaped material connecting pieces, self-tapping screws, lower chord longitudinal steel bars in a one-truss steel bar structure, upper chord longitudinal steel bars and web member wave-shaped steel bars with bent feet. According to the one-truss steel bar floor support plate with the disassembly-free bottom form, the longitudinally-arranged steel bars are single steel bar trusses, compared with triangular steel bar trusses in a steel bar truss floor support plate with a metal bottom form, due to the fact that the number of the lower chord longitudinal steel bars and the number of the web member steel bars used in each truss are both one smaller than the number of the steel bars used in the steel bar truss floor support plate with the metal bottom form, the steel content is greatly reduced, the steel content is closest to that of a traditional cast-in-place slab system, and the bottom of the disassembly-free bottom form can be directly subjected to puttying decoration; and according to the one-truss steel bar floor support plate with the disassembly-free bottom form, the cost is saved for a construction side, the fast turnover target is achieved, the workload of deepening design is saved for a design side, the construction progress is accelerated for the construction side, the construction quality is better controlled, and the productivity is completely released for a component producer, so that all project participants obtain respective benefits.

Description

technical field [0001] The invention relates to the technical field of prefabricated buildings, in particular to a bottom formwork without dismantling-a truss reinforced floor deck. Background technique [0002] The most widely used prefabricated floor slab components in prefabricated steel structure engineering are metal floor steel truss floor decks. Metal floor steel bar truss floor decks are equipped with multiple parallel triangular steel trusses (three-dimensional space), relying on triangular space trusses Contributing stiffness, so during the construction period, it can achieve a large span of more than 2 meters without support, and the overall weight is light, convenient for construction and many other advantages; but the disadvantages are also obvious, because the bottom surface of the metal base plate is smooth, it cannot be putty directly for decoration, and the metal base plate needs to be removed Or make a suspended ceiling for decoration, and the steel content...

Problems solved by technology

[0002] The most widely used prefabricated floor slab components in prefabricated steel structure engineering are metal floor reinforced truss floor slabs. Metal slab steel truss floor slabs are equipped with multiple parallel triangular steel trusses (three-dimensional space), relying on triangular space trusses Contributing stiffness, so during the construction period, it can achieve a large span of more than 2 meters without support, and the overall weight is light, convenient for construction and many other advantages; but the disadvantages are also obvious, because the bottom surface of the metal base plate is smooth, it cannot be putty directly for decoration, and the metal base plate needs to be removed Or make a suspended ceiling for decoration, and the steel content is relatively large, especially in the current market where the price of steel bars is rising fiercely, the cost is slightly high

It is these two shortcomings that affect its application and promotion in the field of concrete construction, especially residential projects
