Description
Technical Field
The invention belongs to the field of environmental protection of coal-fired power plant coal yards, and relates to a totally-enclosed building structure of a net rack membrane structure coal yard.
Background
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.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provides a totally-enclosed building structure of a net rack membrane structure coal yard, which has the advantages of low investment cost, simple maintenance, safety and reliability.
In order to achieve the purpose, the totally-enclosed building structure of the net rack membrane structure coal yard comprises a steel net rack structure and a net rack foundation, wherein the steel net rack structure comprises a net rack upper chord and a net rack lower chord, the net rack lower chord is positioned below the net rack upper chord, the net rack lower chord and the net rack upper chord are connected through a plurality of pressure bars, a light membrane is arranged above the net rack upper chord, the light membrane is connected to the net rack upper chord through a pressure membrane cable belt, and the end part of the net rack upper chord and the end part of the net rack lower chord are both fixed on the net 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 invention has the following beneficial effects:
the invention relates to a totally-enclosed building structure of a net rack membrane structure coal yard, which adopts net rack design, cancels purlin design, adopts a light film as an external closed structure, and is a new building structure form between a steel net rack structure colored steel plate and an inflatable membrane structure.
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 invention is described in further detail below with reference to the accompanying drawings:
referring to fig. 1, the totally enclosed building structure of the net rack membrane structure coal yard comprises a steel net rack structure and a net rack foundation 1, wherein the steel net rack structure comprises a net rack upper chord 2 and a net rack lower chord 3, the net rack lower chord 3 is positioned below the net rack upper chord 2, the net rack lower chord 3 is connected with the net rack upper chord 2 through a plurality of pressure bars 5, a light film 6 is arranged above the net rack upper chord 2, the light film 6 is connected to the net rack upper chord 2 through a pressure film rope 7, and the end part of the net rack upper chord 2 and the end part of the net rack lower chord 3 are both fixed on the net rack foundation 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.
After the roof net rack is formed by steel members, the tensioned light membrane 6 is arranged on the net rack according to design requirements, the building system is self-balanced and has good stability, the roof is simple in shape, and the opening part is not limited.
In the same span coal yard closed, the net rack membrane structure coal yard totally-enclosed building has the following characteristics. The unit investment of the film material is lower than that of the color steel plate, and the shape is kept without using an air blower for inflation as in the air film structure; as the purlines are cancelled, the coal yard with the same scale is closed, and the steel consumption for per square meter of the net rack film scheme is saved by about 5kg compared with that of the net rack structure scheme; the weight of the enclosure structure is lighter relative to that of the color steel plate; the light transmittance of the film material can reduce the electricity consumption for building illumination; the construction period is slightly shorter than that of the grid structure; compared with a color steel plate, the film material is more resistant to corrosion of various strong acids and strong bases, and the maintenance cost is lower in the service life.
The technical idea of the present invention is described above only, and the scope of the present invention should not be limited thereby, and any modification made based on the technical idea of the present invention is within the scope of the present invention.
