Description
Technical Field
The utility model relates to a fire prevention apron for industrial building specifically is a light-duty fire prevention apron.
Background
The high-rise factory building or large-scale factory building area is big, the number of piles is many, and according to the fire prevention standard requirement of country, each floor is as independent fire prevention subregion, if there is the trompil, unsatisfied independent fire prevention subregion requirement, must run opposite directions the hole and adopt the apron shutoff.
In industrial buildings, openings are often required. In order to not affect fire partition division, a cover plate is required to be arranged to seal the holes, the cover plate is required to meet a certain fire resistance limit, and the influence of fire on other floors cannot be influenced while the influence of fire on each floor is avoided; meanwhile, when the cover plate needs to be hoisted, the cover plate needs to meet the requirements of opening and hoisting.
The prior hole cover plate comprises a metal cover plate, a reinforced concrete cover plate and a light fireproof material cover plate. Common hole cover board is mostly metal covering board and reinforced concrete apron, and its self weight is big, and hoist and mount are inconvenient, open difficulty, fire behavior is poor. The metal cover plate needs to be coated with fireproof paint on the surface to meet the requirement of the fire resistance limit, the surface coating is easy to collide and fall off in the opening process, and the fire resistance limit is difficult to guarantee. The light fireproof material cover plate cannot meet the bearing requirement, severe consequences such as falling of workers are easily caused in the trampling process, and the fire resistance limit of the standard requirement cannot be met.
Disclosure of Invention
The utility model aims to solve the technical problem that, to prior art not enough, provide a light-duty fire prevention apron, this fire prevention apron has characteristics such as bearing, fire prevention, matter light, easy equipment concurrently, and opens the convenience, is difficult impaired.
The utility model provides a technical scheme that above-mentioned technical problem adopted does: the utility model provides a light-duty fire prevention apron, includes support chassis and rock wool layer, the rock wool layer fill the setting and be in support chassis's inboard, the both sides surface on rock wool layer cover respectively and be equipped with the light PLASTIC LAMINATED, every the surface of light PLASTIC LAMINATED cover and be equipped with the steel sheet, every the steel sheet fix support chassis on, wherein one the four corners welding on surface of steel sheet have metal rings.
The utility model discloses protection cover plate adopts the equipment structure of support chassis, rock wool layer, light PLASTIC LAMINATED and steel sheet, has alleviateed the weight of apron greatly, and rock wool layer and light PLASTIC LAMINATED combined use simultaneously can effectively improve fire behavior to this fire protection cover plate has characteristics such as bearing, fire prevention concurrently, matter light, easy equipment, and opens the convenience, is difficult impaired. When the fireproof cover plate is used, the holes can be sealed by placing a plurality of blocks on the floor slab around the holes according to the size of the holes in the floor slab.
Preferably, the support framework comprises a main keel and a secondary keel which are connected into a whole, the main keel is arranged along the periphery of the rock wool layer, the secondary keel is fixed on the main keel, and the secondary keel is arranged at intervals along the length direction of the main keel. The supporting framework can ensure that the bearing capacity of the fireproof cover plate meets the requirements.
Furthermore, the main keel and the auxiliary keel are respectively made of I-shaped steel or channel steel, and the auxiliary keel is welded on the main keel.
Preferably, the volume weight of the rock wool layer is 80-150 kg/m3。
Preferably, the light fireproof plate is a calcium silicate plate or a fireproof gypsum plate.
Preferably, the thickness of the light fireproof plate is 9-25 mm, and the thickness of the steel plate is 3-7 mm.
Compared with the prior art, the utility model has the advantages of as follows: the utility model discloses light-duty fire prevention apron adopts the equipment structure of support chassis, rock wool layer, light PLASTIC LAMINATED and steel sheet, has alleviateed the weight of apron greatly, and rock wool layer and light PLASTIC LAMINATED combined use simultaneously can effectively improve fire behavior to this fire prevention apron has characteristics such as bearing, fire prevention concurrently, matter light, easy equipment, and opens the convenience, is difficult impaired.

Detailed Description
The present invention will be described in further detail with reference to the following embodiments.
The light fireproof cover plate of embodiment 1, as shown in fig. 1, comprises a support framework and a rock wool layer 2, wherein the rock wool layer 2 is filled inside the support framework, and the volume weight of the rock wool layer 2 is 100 kg/m3The outer surfaces of two sides of the rock wool layer 2 are respectively covered with light fireproof plates 3, the outer surface of each light fireproof plate 3 is covered with a steel plate 4, each steel plate 4 is fixed on the supporting framework, and four corners of the surface of one steel plate 4 are welded with metal lifting rings 41.
In embodiment 1, the support chassis is including linking main joist 11 and false keel 12 as an organic whole, and main joist 11 is laid along rock wool layer 2's periphery, and false keel 12 is fixed on main joist 11, and false keel 12 is laid along the length direction interval of main joist 11.
In example 1, the main runner 11 and the cross runner 12 are made of i-steel or channel steel, and the cross runner 12 is welded to the main runner 11.
In example 1, the lightweight fireproof plate 3 was a calcium silicate plate, the thickness of the lightweight fireproof plate 3 was 12 mm, and the thickness of the steel plate 4 was 5 mm.
The light-weight fire-retardant covering sheet of example 2 differs from that of example 1 in that in example 2, the light-weight fire-retardant sheet 3 is a fire-retardant gypsum board.
When the light fireproof cover plate is used, the holes can be sealed by placing a plurality of blocks on the floor slab around the holes according to the size of the holes in the floor slab.
The effect diagrams of the light fireproof cover plate placed on the floor slab around the hole in a lap joint mode are shown in figures 2-4. The holes 5 are located on the building floor 6, adjacent to the wall 7, and inside the balustrade 8. The 3 light fireproof cover plates (i.e. the plates 1, 2 and 3 in fig. 2) are overlapped on the floor slab 6 around the hole 5, and the hole 5 is sealed.
