Abstract
The invention discloses a steel plate polyvinyl alcohol cement-based composite anti-explosion plate which comprises a polyvinyl alcohol composite filler, a foamed aluminum filler, a supporting plate, a U-shaped groove steel plate, a high-strength bolt and a steel cushion block, wherein the polyvinyl alcohol composite filler is arranged on the steel plate; a foamed aluminum filler is arranged between the two polyvinyl alcohol composite fillers; inserting two support plates into the grooves of the U-shaped groove steel plate to form a cavity; placing the polyvinyl alcohol composite filler sandwiched with the foamed aluminum filler in the cavity; the supporting plate and the U-shaped groove steel plate are provided with symmetrically arranged bolt holes; the supporting plate and the U-shaped groove steel plate are connected on the polyvinyl alcohol composite filling body through high-strength bolts; and a steel cushion block is arranged between the U-shaped groove steel plate and the high-strength bolt. The explosion-proof plate has the advantages of simple structure, light weight, high strength, and the capability of dissipating and absorbing explosion energy, and because the steel plate is used as the cavity of the explosion-proof plate, the structure is simple, the weight is light, fragments are not easy to generate, secondary disasters caused by the fragments are effectively avoided, and the explosion-proof plate can be better used for buildings with explosion-proof requirements.
Description
Technical Field
The invention relates to the technical field of building structures, in particular to a steel plate polyvinyl alcohol cement-based composite anti-explosion plate.
Background
At present, most building structures adopt reinforced concrete plates, steel reinforced concrete plates and the like as floor slabs, and are used for civil high-rise buildings, multi-storey houses, office buildings, commercial centers and the like. However, the existing reinforced concrete slab and the existing steel reinforced concrete slab do not have the anti-explosion performance, and the reinforced concrete slab or the steel reinforced concrete slab is exploded out of the hole under the action of the explosive load, even the collapse phenomenon occurs, and the local damage of the building structure and the local collapse of the building can be caused.
Disclosure of Invention
In order to solve the technical problems, the invention aims to provide a steel plate polyvinyl alcohol cement-based composite anti-explosion plate, which has the following specific technical scheme:
a steel plate polyvinyl alcohol cement-based composite anti-explosion plate comprises a polyvinyl alcohol composite filler, a foamed aluminum filler, a support plate, a U-shaped groove steel plate, a high-strength bolt and a steel cushion block;
a foamed aluminum filler is arranged between the two polyvinyl alcohol composite fillers; the effects of anti-explosion and energy absorption are achieved;
inserting the two supporting plates into the grooves of the U-shaped groove steel plate to form a cavity;
placing the polyvinyl alcohol composite filler sandwiched with the foamed aluminum filler in a cavity;
the supporting plate and the U-shaped groove steel plate are provided with symmetrically-arranged bolt holes;
the supporting plate and the U-shaped groove steel plate are connected to the polyvinyl alcohol composite filling body through high-strength bolts;
and a steel cushion block is arranged between the U-shaped groove steel plate and the high-strength bolt.
The preferable scheme of the steel plate polyvinyl alcohol cement-based composite anti-explosion plate is that the U-shaped groove steel plate is formed by welding three steel plates.
The preferable scheme of the steel plate polyvinyl alcohol cement-based composite anti-explosion plate is that the polyethylene cement composite filler is formed by casting in a cast-in-place mode.
The invention has the beneficial effects that: the invention provides a steel plate polyvinyl alcohol cement-based composite anti-explosion plate with anti-explosion performance, and the polyvinyl alcohol cement-based composite material has great bending deformation capacity through the energy absorption characteristic of a foamed aluminum filling body, and the generated cracks during bending deformation are fine and micro cracks distributed in the tensile region of the bending deformation and have certain impact capacity. Therefore, the anti-knock board is formed by the foamed aluminum filler, the polyvinyl alcohol cement-based composite material and the support plate and the U-shaped groove, and has extremely high toughness. The anti-explosion plate treated by the method is used as a floor slab of a building structure, and the anti-explosion performance is improved, so that the condition that the floor slab is damaged or even collapses due to internal explosion of an important building structure to cause casualties and damage to facilities is avoided. The utility model discloses can be used for multilayer among the civil residential building, high-rise floor structure, the floor structure of commercial center building, the floor structure of office building as have the building structure of antiknock requirement in, can adopt the compound anti-explosion board of this invention steel sheet polyvinyl alcohol cement base to play blast proof measure to building structure's such as multilayer, high-rise civil residential building, commercial center building, office building floor.

Detailed Description
As shown in fig. 1-2, the steel plate polyvinyl alcohol cement-based composite explosion-proof plate comprises a polyvinyl alcohol composite filler 1, a foamed aluminum filler 2, a support plate 3, a U-shaped groove steel plate 4, a high-strength bolt 5 and a steel cushion block 6;
a foamed aluminum filler 2 is arranged between the two polyvinyl alcohol composite fillers 1;
inserting the two support plates 3 into the grooves of the U-shaped groove steel plate 4 to form a cavity;
placing the polyvinyl alcohol composite filler 1 sandwiched with the foamed aluminum filler 2 in a cavity;
the supporting plate 3 and the U-shaped groove steel plate 4 are provided with symmetrically-arranged bolt holes;
the supporting plate 3 and the U-shaped groove steel plate 4 are connected to the polyvinyl alcohol composite filling body through a high-strength bolt 5;
and a steel cushion block 6 is arranged between the U-shaped groove steel plate 4 and the high-strength bolt 5.
The U-shaped groove steel plate 4 is formed by welding three steel plates.
And casting in a cast-in-place mode to form the polyethylene cement composite filling body.
