Abstract
The utility model discloses a kind of airduct passing through floors fire proof construction, comprise horizontally disposed floor and vertically arrange and pass the airduct of described floor, it is characterized in that: described floor location place is provided with fire proof construction in described airduct, described fire proof construction comprises and is welded on the horizontally disposed short brace of airduct inwall, the hot melt sheet be connected with described short brace, is connected and is positioned at the metal gate valve below described short brace with described hot melt sheet.By being arranged at the metal gate valve that hot melt sheet is connected, when the intensity of a fire along airduct spread and on burn hot melt sheet time, hot melt sheet fuses, and now metal gate valve will be taken advantage of a situation and to be rotated around pin joint, thus blocks whole airduct internal diameter completely, avoids the intensity of a fire upwards.
Description
Technical field
The utility model relates to fire proof construction, particularly relates to a kind of airduct passing through floors fire proof construction.
Background technology
Owing to needing the layout of carrying out pipeline in floor structure, often need to be passed from floor by airduct, when client needs pipeline to pass, pipeline can be allowed to pass from airduct and avoid pounding wall, fire proof seal process will be carried out during use, and be embedded with a lot of airducts at the beginning of building in order to follow-up use, so for empty untapped, once a certain resident family catches fire, the intensity of a fire will be spread along the airduct of sky.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of airduct passing through floors fire proof construction, can effectively completely cut off burning things which may cause a fire disaster and spread.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of airduct passing through floors fire proof construction, comprise horizontally disposed floor and vertically arrange and pass the airduct of described floor, described airduct is hollow cylindrical structure, its innovative point is: in described airduct, described floor location place is provided with fire proof construction, described fire proof construction comprises and is welded on the horizontally disposed short brace of airduct inwall, the hot melt sheet be connected with described short brace, be connected with described hot melt sheet and be positioned at the metal gate valve below described short brace, described metal gate valve comprises horizontally disposed connecting rod, be welded on the auxiliary contiguous block of the vertical setting of welding on described connecting rod and with described hot melt sheet, weld and be arranged on described horizontally disposed connecting rod and the second contiguous block be positioned at immediately below described horizontally disposed connecting rod, the valve metal film hinged with described second contiguous block, gap is left between described valve metal film and described airduct inwall when described hot melt sheet does not fuse, and gapless between described valve metal film and described airduct inwall during the fusing of described hot melt sheet.
Preferably, described horizontally disposed connecting rod is at least provided with described second contiguous block hinged with described valve metal film.
Preferably, on described airduct inwall, welding is provided with spacing short-movie, and described spacing short-movie props up described valve metal film when hot melt sheet does not fuse.
Preferably, on described airduct inwall, at least welding is provided with a described spacing short-movie.
Preferably, the airduct part that described airduct contacts with described floor has swathed fire proofing material.
Preferably, described airduct has swathed material which can retain moisture away from the airduct part of described floor.
The invention has the advantages that: by being arranged at the metal gate valve that hot melt sheet is connected, when the intensity of a fire along airduct spread and on burn hot melt sheet time, hot melt sheet fuses, and now metal gate valve will be taken advantage of a situation and to be rotated around pin joint, thus block whole airduct internal diameter completely, avoid the intensity of a fire upwards.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the structural representation of a kind of airduct passing through floors of the utility model fire proof construction.
In figure: 1-floor, 2-airduct, the short brace of 3-, 4-hot melt sheet, 5-connecting rod, 6-assist contiguous block, 7-second contiguous block, 8-valve metal film, the spacing short-movie of 9-, 10-fire proofing material, 11-material which can retain moisture.
Detailed description of the invention
A kind of airduct passing through floors fire proof construction of the present utility model comprises horizontally disposed floor 1 and vertically arranges and pass the airduct 2 of floor 1, and airduct 2 is hollow cylindrical structure.In airduct 2, floor 1 position is provided with fire proof construction, fire proof construction comprises and is welded on the horizontally disposed short brace 3 of airduct 2 inwall, the hot melt sheet 4 be connected with short brace 3, be connected with hot melt sheet 4 and be positioned at the metal gate valve below short brace 3, metal gate valve comprises horizontally disposed connecting rod 5, be welded on the auxiliary contiguous block 6 of the vertical setting of welding on connecting rod 5 and with hot melt sheet 4, weld and be arranged on horizontally disposed connecting rod 5 and the second contiguous block 7 be positioned at immediately below horizontally disposed connecting rod 5, the valve metal film 8 hinged with the second contiguous block 7, gap is left between valve metal film 8 and airduct 2 inwall when hot melt sheet 4 does not fuse, and hot melt sheet 4 gapless between valve metal film 8 and airduct 2 inwall when fusing.
In order to ensure the rotate effect of valve metal film 8, horizontally disposed connecting rod 5 is at least provided with second contiguous block 7 hinged with valve metal film 8.
When not fusing to prevent hot melt sheet 4, metal gate valve is conducted oneself with dignity and pulls apart hot melt sheet 4, and on airduct 2 inwall, welding is provided with spacing short-movie 9, and spacing short-movie 9 props up valve metal film 8 when hot melt sheet 4 does not fuse.In order to ensure result of use, on airduct 2 inwall, at least welding is provided with a spacing short-movie 9.
In order to ensure flameproof effect, airduct 2 part that airduct 2 contacts with floor 1 has swathed fire proofing material 10; Airduct 2 has swathed material which can retain moisture 11 away from airduct 2 part of floor 1.
By being arranged at the metal gate valve that hot melt sheet 4 is connected, when the intensity of a fire along airduct 2 spread and on burn hot melt sheet 4 time, hot melt sheet 4 fuses, and now metal gate valve will be taken advantage of a situation and to be rotated around pin joint, thus blocks whole airduct 2 internal diameter completely, avoids the intensity of a fire upwards.
Above an embodiment of the invention has been described in detail, but content being only the preferred embodiment of the invention, the practical range for limiting the invention can not being considered to.All equalization changes done according to the invention application range with improve, within the patent covering scope all belonging to the invention.
