Abstract
The utility model relates to a fire-proof plugging sheet material which is used for openings formed when cables, pipelines and the like pass through floor slabs or walls in fire-proof sealed buildings, or used as fire baffle walls of cable trenches and cable tunnels. The utility model belongs to fire-proof plugging materials. The fire-proof plugging sheet material comprises at least two layers ofmineral wool slabs and at least one layer of steel mesh which are pressed, wherein the upper and the lower surface layers are the mineral wool slabs, and at least 0.1-thickness fire-proof coatings arecoated on the surfaces of the mineral wool slabs. The fire-proof plugging sheet material can be cut into any shape for being suitable for fire-proof plugging of openings with various sizes and penetrating objects in use. The fire-proof plugging sheet material can be matched with fire-proof seal gum for bonding and sealing in construction, thereby having excellent gas tightness and smoke tightness.
Description
Technical field
The utility model relates to a kind of fireproof blocking sheet material, and be used for fire proof seal building cable, pipeline etc. and pass the hole that floor or body of wall form, or as the back-fire relief partition wall of cable duct, cable tunnel.Belong to fire-proof sealing material.
Background technology
Building masonry wall and floor inevitably will be reserved hole and pass in order to allow cable, pipeline etc. to run through thing when design, this has destroyed as the body of wall of fire separation member and the fire endurance of floor.If fireproof blocking can not be carried out effectively in these apertures, at first be that fire compartment has lost integrality and validity, secondly, in the fire, these holes will become the passage of flame, smog and toxic gas, cause huge property loss and casualties.
The material that is commonly used to these holes of fireproof blocking has back-fire relief bag, anti-chamotte and inorganic putty, and these materials appear its great defective and drawback in the uses of more than ten years in the past gradually.The close cigarette effect that the fireproof blocking system that can not satisfy the back-fire relief bag should play also can't satisfy the air-tightness requirement of some special industry needs, and back-fire relief wraps in the work progress the very difficult control of construction quality, is difficult to the anti-fire action that guarantees that it should reach.Anti-chamotte majority contains chlorinated paraffin wax and organic solvent, and long-term use meeting causes corrosion to cable and metal crane span structure, pipeline etc., forms disaster hidden-trouble on the contrary.Inorganic putty range of application is narrow, and cracking, construction inconvenience easily.
In addition, these products also are not suitable for the fireproof blocking of large hole, can not satisfy the specification requirement as cable tunnel, cable duct back-fire relief partition wall.
Summary of the invention
At above-mentioned deficiency, the purpose of this utility model provides a kind of hole that fire proof seal building cable, pipeline etc. pass floor or body of wall formation that is used for, particularly seal large hole and, can guarantee close property of good cigarette and bubble-tight fireproof blocking sheet material after the installation as the back-fire relief partition wall of cable duct, cable tunnel.
This fireproof blocking sheet material by two-layer at least mineral wool board and at least one deck steel screen layer press and to form, the upper and lower surface layer is a mineral wool board, the mineral wool board surface applied is the thick fire resistant coating of 0.1mm at least.
Described mineral wool board is at least a in the rock cotton board, aluminium silicate wool plate, ceramic beaverboard of high-intensity high-density, and its compressive strength is that apparent density is greater than 100kg/m greater than 2kPa
3This mineral wool board has good self-supporting ability and heat-proof quality.
Described steel wire is selected from galvanized hexagonal wire mesh, embroider net, twist at least a in the flower net.Its tension, tear-proof that is used to increase fireproof blocking sheet material is shock resistance together, the impact property of anti-fire-fighting lance when particularly increasing test.
Described fire resistant coating has the fiery carbonization expansion character of chance, and expansion charcoal layer has good anti-ablation property and heat-proof quality.
In use, this fireproof blocking sheet material can cut into arbitrary shape to be suitable for various bore hole sizes and the fireproof blocking that runs through thing.Cooperate fireproof seal gum during construction, thereby reach excellent air-tightness and the close property of cigarette in order to bonding and fluid sealant.
Below in conjunction with accompanying drawing the utility model is further described.
