Embodiment 1

[0045] The fire protection structure provided by this embodiment, such as Figure 1 to Figure 13 As shown, it includes a plurality of fireproof modules; each fireproof module includes a skeleton 3 and a surface fireproof layer 4, and the surface fireproof layer 4 is fixedly connected to the outer surface of the skeleton 3 by fasteners; the skeleton 3 of a plurality of fireproof modules is connected in sequence to A plurality of surface fireproof layers 4 are formed into a closed cylindrical shape, and adjacent skeletons 3 are clamped and / or fixedly connected by fasteners, and the plurality of skeletons 3 can be matched and fixedly sleeved on the component 1 .

[0046] Wherein, the adjacent frameworks 3 can be fixed by clamping, can be fixed by fasteners, or can be fixed by clamping, and then the adjacent frameworks 3 can be further fixed by fasteners.

[0047] When the fire protection structure is assembled with the component 1, the fire protection structure is directly fixed ...

Embodiment 2

[0086] The fabricated structure provided in this embodiment includes component 1 and the fire protection structure provided in this embodiment. When the fire protection structure is assembled with the component 1, the fire protection structure is directly fixed and sleeved on the component 1, the frame 3 of the protective device does not need to be welded with the component 1, and the frame 3 and the surface fireproof layer 4 are connected by fasteners , the adjacent frames 3 are fixed by clamping and / or fasteners, and the whole assembly process does not require welding work, so that the process of assembling the fire protection structure is more convenient, and no welding work can reduce the risk of fire.

[0087] Further, the cross-sectional shape of the component 1 is rectangular or I-shaped, and the component 1 can be used as a beam, a column or a diagonal support member.

Abstract

The invention provides a fireproof protective structure and an assembly type structure, and relates to the fireproof technical field. The fireproof protective structure comprises a plurality of fireproof modules, wherein each fireproof module comprises a framework and a surface fireproof layer, and the surface waterproof layer is fixedly connected to the outer surface of the framework through a fastening part; the frameworks of the multiple fireproof modules are sequentially connected, and the multiple surface fireproof layers define a sealed barrel shape, adjacent frameworks are in blocking connection and / or are fixedly connected through the fastening part; and the multiple frameworks can be matched and in fixed sleeve connection on components. While the fireproof protective structure isassembled with the components, the fireproof protective structure is directly in sleeve connection on the components, and the frameworks of the fireproof protective device do not need to weld with thecomponents; moreover, the frameworks and the surface fireproof layers are connected through the fastening parts, the adjacent frameworks are fixed by blocking connection and / or the fastening parts, and the whole assembly process does not need welding operation, so that the assembly process of the fireproof protective structure is relatively convenient; and moreover, fire risk can be reduced as welding operation is absent.

Description

technical field [0001] The invention relates to the technical field of fire protection, in particular to a fire protection structure and an assembled structure. Background technique [0002] The prefabricated steel structure building has the characteristics of construction industrialization and housing industrialization. It is the product of the transformation of traditional construction methods to modern construction methods such as intensive, economical, green, environmental protection and technology. It is also a new carrier of green buildings, and the steel used in buildings can be Recycling has broad development prospects and far-reaching social value. [0003] Although the prefabricated steel structure has the above advantages, the fire resistance of the steel structure is poor. When the temperature exceeds 300°C, the strength of the steel will decay rapidly, and the bearing capacity of the steel will decrease by 70% when the temperature exceeds 500°C. Fire protection...
