Steel plate and polyvinyl alcohol cement based composite antiknock board

Abstract

The invention discloses a steel plate and polyvinyl alcohol cement based composite antiknock board which comprises two polyvinyl alcohol composite fillers, a foamed aluminum filler, two supporting plates, U-shaped-channel steel plates, high-strength bolts and steel cushion blocks. The foamed aluminum filler is arranged between the two polyvinyl alcohol composite fillers; the two supporting plates are inserted in channels of the U-shaped-channel steel plates to form a cavity in a surrounding way; the polyvinyl alcohol composite fillers, with the foamed aluminum filler between them, are arranged in the cavity; the supporting plates and the U-shaped channel steel plates are provided with bolt holes in symmetrical arrangement, and are connected to the polyvinyl alcohol composite fillers through the high-strength bolts; the steel cushion blocks are arranged between the U-shaped-channel steel plates and the high-strength bolts respectively. The steel plate and polyvinyl alcohol cement based composite antiknock board has the advantages of simple structure, light weight, high strength and high capacity of dissipating and absorbing explosion energy. To be specific, as the steel plates are used for making the cavity of the antiknock board, the antiknock board is simple in structure, is light, is not easy to fragment so as to effectively avoid secondary disasters caused by fragments, and accordingly is effectively applicable to buildings having requirements on explosion protection.

Description

technical field [0001] The invention relates to the technical field of building structures, in particular to a steel plate polyvinyl alcohol cement-based composite anti-explosion board. Background technique [0002] At present, most building structures use reinforced concrete slabs and steel concrete slabs as floor slabs, which are used for civil high-rises, multi-storey residences, office buildings, commercial centers, etc. However, the existing reinforced concrete slabs and shaped steel concrete slabs do not have anti-blast performance. Under the action of explosion loads, the reinforced concrete slabs or shaped steel concrete slabs are blown out of holes, and even collapse occurs from time to time, which will cause local damage to the building structure. Even cause partial collapse of the building. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the object of the present invention is to provide a steel plate polyvinyl alcoho...
