Embodiment 1

[0043] see Figures 1 to 6 The shown embodiment 1 of the broken-line profiled hollow steel plate of the present invention includes two layers of profiled steel plates combined and fixed to form a hollow structure, and the two layers of profiled steel plates are nested and matched with each other. Specifically, it includes a locking plate 1 and a bone buckling plate 2 . Each locking plate 1 is formed by bending at least one steel plate. Each bone buckle plate 2 is formed by bending at least one steel plate.

[0044] The locking plate 1 is provided with a plurality of downward opening cavities 11 along the horizontal direction, and the cavities 11 are bent multiple times by the locking plate 1 to form an inverted trapezoidal cross-sectional shape at the top horizontal lower end; The cavity one 11 is horizontally symmetrical along the vertical axis, forming a symmetrical pressure bearing capacity. A locking plate gap 12 is provided between the outer walls of each adjacent cavi...

Embodiment 2

[0056] see Figures 7 to 11 The difference between the shown embodiment 2 of the broken-line profiled hollow steel plate of the present invention and the embodiment 1 is that the bone buckle plate 2 is two layers nested in sequence.

[0057] The support body 21 includes a stacked first support unit 215 and a second support unit 216, the first support unit 215 and the second support unit 216 are formed by continuous reverse bending of the bone deduction plate 2 . Specifically, the bone buckle plate 2 is bent into a first side 201 , a second side 202 , a third side 203 , a fourth side 204 , a fifth side 205 , a sixth side 206 , a seventh side 207 and an eighth side 208 .

[0058] The first side 201 , the second side 202 , the seventh side 207 , and the eighth side 208 constitute the second support unit 216 and together form the second cavity formed in the second support unit 216 . The third side 203, the fourth side 204, the fifth side 205, and the sixth side 206 together form...

Embodiment 3

[0069] see Figures 12 to 15 The shown embodiment 3 of the folded-line profiled hollow steel plate of the present invention is different from the embodiment 2 in that the bone deduction plate 2 is continuously bent to form three fold-line-shaped supports 21 and the support The three cavities formed inside the body 21 include the first support unit 221, the second support unit 222, the third support unit 223 and the first cavity 231, the second cavity 232, the third cavity 233, except the Each cavity of the bone deduction plate 2 outside the first cavity is nested with the support body 21 of the bone deduction plate 2 of the next layer.

[0070] In this embodiment, there is a support body gap between every two adjacent second support units and two adjacent third support units. Each adjacent two second supporting units 222 are stretched horizontally to form contact, and at the same time, the outer walls of two adjacent third support units 223 are horizontally expanded to form c...

Abstract

The invention discloses a fold line type profiled hollow steel plate. The fold line type profiled hollow steel plate comprises locking plates, wherein a plurality of cavities I are formed in the locking plates in the horizontal direction; each locking plate is formed by bending a steel plate; the profiled steel plate is arranged as a buckling bone plate; a plurality of supporting bodies are arranged on the buckling bone plate in the horizontal direction; each supporting body is a fold line type supporting body formed by bending a steel plate; a cavity is formed in each supporting body; and when the locking plates are connected with the buckling bone plate, the supporting bodies are nested in the cavities I. According to the profiled hollow steel plate disclosed by the invention, through the profiled hollow steel plate and the unique space design, excellent section characteristics are obtained, the bearing capacity of a component is improved, and the constant load of a building plate is reduced; hollow lattices are formed among profiled plate layers, so that air convection is obstructed, and the requirements of sound insulation, heat insulation and fire prevention are met; and the profiled hollow steel plate can replace a concrete floor, a concrete wall plate and a roof plate, and is more green and environment-friendly.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a folding line-shaped pressed hollow steel plate. Background technique [0002] The situation of standardized design → factory production → prefabricated construction adopted by prefabricated buildings determines that it is superior to traditional building construction in many aspects, and solves and avoids many difficulties faced by the current traditional construction site. Compared with cast-in-place buildings, the main advantages of prefabricated buildings are high assembly efficiency, high precision, green environmental protection (less construction waste), and can greatly reduce labor dependence. [0003] Prefabricated building components are mainly precast concrete (Precast Concrete, PC) structure, steel structure and wood structure, and the three types of components have their own advantages and disadvantages. The PC structure of prefabricated buildings in my country is...
