Abstract
The utility model discloses interim fire dam of metal mesh relates to a fire dam structure that plays sealed effect in the production process of colliery. Its purpose is in order to provide the interim fire dam of metal mesh that a security height, intensity are high, with low costs. The utility model discloses interim fire dam of metal mesh includes inside frame and wall, inside frame includes the metal crossbeam that metal mainstay that a plurality of vertical directions in edge placed and n root edge horizontal direction were placed, a plurality of metal mainstay align to grid, and the high summary of metal mainstay is greater than the tunnel height, the metal crossbeam connects gradually with the branches such as n+1 of every metal mainstay respectively, and the length of metal crossbeam slightly is greater than the width in tunnel, the wall is located inside frame front and back both sides, and the wall is made by the metal mesh, and the wall surface scribbles fire -retardant sealable coating layer.
Description
Technical field
This utility model relates to technical field of mine safety, particularly relates to a kind of fire dam structure playing sealing function in coal production process.
Background technology
Efficient colliery requisite technology in downhole production of Shi Shuan lane exploitation constructed by underground coal mine temporary airtight wall, is controlling ventilation, is intercepting in the process of the harmful gas such as goaf gas and carbon monoxide and all play an important role.Tradition temporary airtight wall mainly has wooden partition, work stone wall, interim air duct fabric wall, brick wall etc..Protecting against shock fire dam as mining in the one disclosed in Chinese invention patent CN102777208A, arranges wood siding wall in concrete sandwich both sides and fixes.There is the not high defect of safety such as leak out, inflammable that easily ftractureed by down-hole dynamic pressure change in this temporary airtight wall, expend material and manpower, man-hour more simultaneously, relatively costly, is not suitable with the development of modernization high yield and high efficiency mine.
Utility model content
The technical problems to be solved in the utility model is to provide the wire netting temporary airtight wall that a kind of safety is high, intensity is high, cost is low.
This utility model wire netting temporary airtight wall, including inner frame and metope, the metal beam that described inner frame includes the some metal mainstays vertically placed and n root is placed in the horizontal direction, several metal mainstays are evenly distributed, and the height of metal mainstay is slightly larger than head-room, described metal beam is sequentially connected with the n+1 Along ent of each metal mainstay respectively, the length of metal beam is slightly larger than the width in tunnel, both sides before and after the internally positioned framework of described metope, metope is made up of wire netting, and metope outer surface scribbles fire-retardant seal coating.
This utility model wire netting temporary airtight wall, wherein said metal mainstay and metal beam are steel pipe.
This utility model wire netting temporary airtight wall, wherein said metope is spliced by polylith wallboard, and every block of wallboard is made up of one or more layers bar-mat reinforcement and the staggered overlap joint of wire gauze.
This utility model wire netting temporary airtight wall, the aperture of wherein said bar-mat reinforcement is more than 10cm, and the mesh of steel wire is less than 1mm.
This utility model wire netting temporary airtight wall, the thickness of wherein said coating is 3～6mm.
This utility model wire netting temporary airtight wall difference from prior art is in that this utility model wire netting temporary airtight wall adopts the inner frame being made up of metal mainstay and metal beam, and the metope being made up of wire netting is installed outside inner frame, metope scribbles fire-retardant seal coating.The whole inner frame of this utility model wire netting temporary airtight wall and metope adopt all-metal to make, it is ensured that body of wall high intensity under tunnel, will not deform because of down-hole dynamic pressure change and damage.Metope adopts wire netting to coordinate fire-retardant seal coating, it is possible to well play fire-retardant and anlistatig effect, it is prevented that the generation of down-hole contingency.Constitute all optional conventional metal material of material of inner frame and metope, such as steel pipe, reinforcing bar etc., it is possible to that effectively reduces fire dam constructs cost.
Below in conjunction with accompanying drawing, wire netting temporary airtight wall of the present utility model is described further.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model wire netting temporary airtight wall.
Detailed description of the invention
As it is shown in figure 1, this utility model wire netting temporary airtight wall includes inner frame, inner frame includes four metal mainstays being vertically set up in parallel 5 and two metal beam being set up in parallel in the horizontal direction 4.Metal mainstay 5 and metal beam 4 are steel pipe.The diameter of metal mainstay 5 is 5cm, and length is slightly larger than head-room.Four metal mainstays 5 are arranged between the top board 1 in tunnel and base plate 6 uniformly.The top of metal mainstay 5 is arranged in the groove on the downside of back 1, and clamps with chock 7.Two metal beam 4 are fixed with four metal mainstays 5 respectively and are connected, and the diameter of metal beam 4 is 5cm, and length is slightly larger than span length.Two metal beam 4 are connected to two trisection point places of each metal mainstay 5.The two ends, left and right of metal beam 4 reach outside inner frame, and insert among the coal body 3 of the left and right sides, tunnel.Being provided with the metope being spliced into by polylith wallboard 2 on inner frame, wallboard 2 is made up of the staggered overlap joint of one or more layers bar-mat reinforcement and wire gauze, and wherein the aperture of bar-mat reinforcement is more than 10cm, and the mesh of steel wire is less than 1mm.Being coated with fire-retardant seal coating on metope, the thickness of coating is 3～6mm.
This utility model wire netting temporary airtight wall carries out according to following steps when constructing:
1) four metal mainstays 5 of the parallel installation in left and right between the coal body 3 of the left and right sides, tunnel；
2) installing metal beam 4 at the Along ent place of metal mainstay 5, metal beam 4 is fixing with metal mainstay 5 successively to be connected, and constitutes inner frame；
3) metope being overlapped to form by bar-mat reinforcement or steel wire is installed on inner frame；
4) use spray pump at the fire-retardant seal coating of metope surface spraying.
Embodiment described above is only that preferred implementation of the present utility model is described; not scope of the present utility model is defined; under the premise designing spirit without departing from this utility model; various deformation that the technical solution of the utility model is made by those of ordinary skill in the art and improvement, all should fall in the protection domain that this utility model claims are determined.
