With the pursuit of people for good life and longitudinary of beautiful home, under the great promotion of national and local environmental protection policies, the treatment and modification of coal yards of coal-fired power plants enter a comprehensive speed-up stage, the complete sealing of the coal yard is comprehensively realized by newly-built units, and the totally-closed modification of stock unit coal yards becomes a main form of the environmental protection modification of the coal yard. In the totally-enclosed reconstruction of a coal yard of a stock unit, most of the coal yard adopts a steel net rack form, the biggest advantages of the steel net rack are mature technical scheme, long design life and stable and reliable construction, and the problems of large investment, long construction period and great economic burden and cost pressure on enterprises exist. In recent years, a gas film totally-enclosed coal yard also appears, which is a special building structure form, and gas film buildings are gradually popularized and applied in China in recent years due to the advantages of high construction speed, low manufacturing cost, large span, light weight, low requirement on the foundation and the like. However, the air film coal yard needs to continuously blow air inwards to maintain the pressure in the film, and if the power is cut off, the safety of the operation of the air film is threatened, and two paths of mutual standby power supplies and a power supply mode of a diesel generator have to be adopted in the design to ensure the safe operation.
With the rapid development of renewable energy sources, the environmental protection pressure and the cost pressure of coal-fired power plants are continuously increased, researchers continuously explore new structural forms, and in the totally-enclosed reconstruction of coal yards, a comprehensive optimization scheme with reasonable investment cost, simple operation and maintenance and safe and reliable construction is urgently expected to be found.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome above-mentioned prior art's shortcoming, provide a totally closed building structure in rack membrane structure coal yard, the investment cost of this structure is low, and it is simple to maintain, and safe and reliable.
In order to achieve the above object, the totally closed building structure of net rack membrane structure coal yard include steel truss structure and rack foundation, wherein, steel truss structure includes rack upper chord and rack lower chord, wherein, rack lower chord is located the below of rack upper chord, and is connected through a plurality of depression bars between rack lower chord and the rack upper chord, and the top of rack upper chord is provided with the light membrane, and wherein, the light membrane passes through the press film cable tie and connects on rack upper chord, and the tip of rack upper chord and the tip of rack lower chord all are fixed in on the rack foundation.
The net rack lower chord and the net rack upper chord are formed by splicing net rack balls and rod pieces.
A ladder stand and a horse way are arranged in the steel mesh frame structure, and a lighting system is arranged on the side face of the horse way.
The bottom of the steel grid structure is provided with a fire-fighting water pipe and a fire-fighting water cannon.
And an indoor air quality monitoring device, a carbon monoxide and gas concentration monitoring device and an infrared monitoring device are arranged below the steel grid structure.
The utility model discloses following beneficial effect has:
totally closed building structure in rack membrane structure coal yard when concrete operation, adopt the rack design, cancel the purlin design, outside enclosed construction adopts light membrane simultaneously, its new building structure form between steel rack structure adds various steel sheet and aerifys the membrane structure, the utility model discloses utilize the steel rack as building inside support frame, the outside adopts light membrane to seal to reduce the investment cost of coal yard low, maintain simultaneously simply, safe and reliable, the practicality is extremely strong.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Wherein, 1 is the net rack basis, 2 is net rack upper chord, 3 is net rack lower chord, 4 is the net rack ball, 5 is the depression bar, 6 is the light film, 7 is the film pressing rope, 8 is the cat ladder, 9 is the packway, 10 is fire-fighting water pipe, 11 is the fire water cannon, 12 is lighting system, 13 is indoor air quality monitoring devices, 14 is carbon monoxide and gas concentration monitoring devices, 15 is infrared monitoring devices.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings:
referring to fig. 1, the totally closed building structure of net rack membrane structure coal yard include steel truss structure and rack basis 1, wherein, steel truss structure includes rack upper chord 2 and rack lower chord 3, wherein, rack lower chord 3 is located the below of rack upper chord 2, and is connected through a plurality of depression bars 5 between rack lower chord 3 and the rack upper chord 2, and the top of rack upper chord 2 is provided with light film 6, wherein, light film 6 connects on rack upper chord 2 through press mold cable 7, and the tip of rack upper chord 2 and the tip of rack lower chord 3 all are fixed in on rack basis 1.
The net rack lower chord 3 and the net rack upper chord 2 are formed by splicing net rack balls 4 and rod pieces; a ladder stand 8 and a riding track 9 are arranged in the steel net rack structure, and a lighting system 12 is arranged on the side surface of the riding track 9; the bottom of the steel grid structure is provided with a fire-fighting water pipe 10 and a fire-fighting water cannon 11; an indoor air quality monitoring device 13, a carbon monoxide and gas concentration monitoring device 14 and an infrared monitoring device 15 are arranged below the steel net rack structure.
The steel truss structure of the totally closed building of the coal yard adopts the design without purlin, the building appearance adopts the form of three-core circle structure, the outside of the building and gable walls on both sides are sealed by light film 6.
