Abstract

The fire resistant structural panel with a PIR core relates to the construction branch, namely to the composite elements of building construction, and is intended for the manufacture of fire resistant load bearing structures.
A fire resistant structural panel with a polyisocyanurate PIR core is composed of outer upper and lower boards, an adhesive material, a strut framework and a filler. Wherein the strut framework is made as contiguous regular hexagons (honeycomb).
The outer boards and the strut framework (4) are made of cement-cellulose and the filler (5) is a polyisocyanurate foam PIR.
All strut framework (4) is made of strips (7) which have a form based on a half of hexagon wherein the strips (7) are assembled to create cells (6) of the strut framework (4) and they have at least one round hole (8) on a side of the hexagon.

Description

  • The claimed invention relates to the construction branch, namely to the composite elements of building construction, and is intended for the manufacture of fire resistant load bearing structures.
  • There are many different materials for the outer shell and inner core, different design and methods of connection panels. Well know are structural panels with internal structure.
  • For example, the known three-layer wall panel SU727786 , consisting of outer layers made of asbestos board, adhesive materials, packages of mineral wool panels and edges in polyester foam. The disadvantage of this invention is a low load strength.
  • Also known patent US 2011/0047932 which one's building panel consists of upper and lower outer board (preferably laminated), an adhesive material and a matrix of structural stiffeners. This building achieves better results as to structural load bearing capacity than the previous panel however the absence of a filling material reduces final resistance characteristics.
  • The closest to the claimed invention is a honeycomb panel described in the patent RU 136 064 , which consists of the outer upper and lower board, an adhesive material, a matrix of structural stiffeners shaped in a form of attached to one another regular hexagons (honeycomb) and a filler, for which are used dry bulk materials or polymerizing materials. The material used for the outer board is or a thin metal sheet (steel, aluminum, zinc aluminum alloy) or a foil, or a fiberglass, or a carbon fiber, an aramid or a cloth or a paper sheet.
  • All these materials have poor fire resistance properties and as inside stiffeners are formed monolithically, it is difficult to manufacture. When as a filler is used dry loose material, the inner cells do not participate in the load transmission, what reduces the load bearing properties of the panel. Polymerizing materials fill the inner structure completely, however materials proposed for that purpous, in the mentioned patent description, are fragile and have low profile of fire resistance properties.
  • As a base for this invention is a task to create a structural fire resistant panel by adapting its core strut framework, its outer board layers, its core filler, to higher fire resistance requirements, load bearing and to simplify its fabrication.
  • The problem is solved in the present invention by a fire resistant structural panel with a polyisocyanurate PIR core, consisting of an outer upper and lower boards, an adhesive material, a strut framework inserted between the outer boards, wherein the strut framework made as a regular contiguous hexagons (a honeycomb) and a filler placed inside the strut framework cells, wherein the outer layers and struts are made of cement-cellulose and a polyisocyanurate foam PIR is the filler and all struts are made of strips formed on a base of a half of regular hexagon, wherein the strips are assembled to form regular hexagon strut framework with at least one round hole in side of each half of hexagon.
  • The present invention, in an exemplary, but not exhaustive embodiment, is visualized in the drawings:
    • Figure 1 - a general view of the fire resistant structural panel with a polyisocyanurate PIR core with w partial cut of the top board.
    • Figure 2 - a general view of the strut framework
    • Figure 3 - a detailed view of struts
    • Figure 4 - a detailed view of assembled strut framework
  • The claimed fire resistant structural panel with a polyisocyanurate PIR core is composed of outer upper 1 and lower 2 boards, an adhesive material 3, a strut framework 4 inserted between the outer upper 1 and lower 2 boards and a filler 5 placed inside cells 6 formed by the strut framework 4. The strut framework 4 is made as a regular contiguous hexagons (a honeycomb). Wherein all struts are made of strips 7 assembled to form the cells 6 of the strut framework 4, the strips have at least one round hole 8 on a side of the hexagon.
  • Each cell 6 of the strut framework 4 is filled by the filler 5 made of a polyisocyanurate foam PIR, which is poured by the round holes on sides of the hexagons.
  • Both outer boards of the panel and the strut framework's strips are produced of cement-cellulose what increase considerably the fire resistance properties of the panel. Also the quality of the polyisocyanurate foam PIR increase those characteristics. The strips have at least one hole on a side of each half of a hexagon what facilitates accurate fulfilment of inner cells of the strut framework by the polyisocyanurate foam PIR what enables a transmission of loads by the panel's core, enhancing by this mechanical properties of the panel. The fabrication is also simplified by the fact, that the strut framework is composed of modular, repetitive strips.
