The price of LED display screen is mainly composed of screen price, control system, computer amplifier sound class, engineering construction and so on.
The screen body and control system are provided by professional LED display manufacturers (yuan/square meter, the control system depends on the size of the screen area), for a penny of goods, it is recommended that customers choose the products that are suitable for their own use, not just look price.
The price of civil engineering infrastructure consists of earthwork excavation backfill, concrete, steel and other materials and machinery and labor costs. The quotation of this part is the unit of earthwork and concrete, which is the unit of price, that is, yuan/square. The weight of steel bar is the unit of price, that is, yuan/ton. The number of days of construction is the unit of quotation, that is, yuan/workday. The general valuation can be unified for the volume of reinforced concrete, which can be valued between 1000-1500 yuan, and the price is lower when the volume is large. The volume of the foundation of the civil engineering is generally equal to the area of ​​the upper screen. For example, the general base volume of a 40-square screen is about 40 square meters. The actual parameters need to be designed by a professional design institute.
The price of the steel structure frame consists of steel materials, steel materials, rework, welding labor, and auxiliary materials. The re-processing of steel materials and materials is quoted in terms of weight, that is, yuan/ton. Welding labor is based on the number of days, that is, yuan/workday. The general valuation can be uniformly priced as the weight of the steel material, ie yuan/ton. Steel materials are generally 5500-7000 yuan / ton (adjusted according to market prices), plus in the general 1000-1500 yuan / ton (adjusted according to reprocessing methods), welding labor is generally 2000-3500 yuan / ton, auxiliary materials in 500 Yuan/ton or so, so the general steel structure construction is 9,000-11,000 yuan / ton (excluding reprocessing). In the LED display project, the general frame weight can be estimated at 0.15 ton / square meter. If the column is installed, the column is estimated to be 0.4 ton / m, and the double column should be doubled.
The price of the exterior decoration project consists of decorative materials, decorative labor, and auxiliary materials. The quotation of decorative materials and auxiliary materials is based on the area of ​​the unit of price, that is, yuan/square meter, and the decoration labor is based on the number of days, that is, yuan/workday. The general valuation can be uniformly priced as the area of ​​the decorative material, ie yuan/square meter. Aluminum-plastic panel (double-sided) decoration is generally 450-650 yuan / square meter. The LED display is like a hexahedron. As long as all the surface area is subtracted from the display area, it is the decorative area, plus 15% of the processing loss is the final area.
The price of the strong and weak electric wiring project consists of cables, pipeline trunking, installation of pipeline trunking, and labor for laying the line. Cables, pipeline trunking and installation are all based on the length of the unit of price, that is, yuan / meter, the line of labor is based on the number of days, that is, yuan / working day. The general valuation can be unified for the calculation of the wiring length. Because the price specifications of the line pipe and the wire slot are many and the installation methods are different, this part of the quotation is difficult to be empirically calculated, and can only be actually calculated. In actual engineering, this line pipeline slot can generally utilize weak current engineering. Already laid, if the construction can only be calculated according to the actual situation. There are many specifications for strong electric cables, and the market price changes greatly. Therefore, cables with large cross-sections should be placed in place by Party A as much as possible. Among the weak current cables, the 8-core network cable is generally estimated at 4 yuan/m2, and the shielded flexible cable is generally estimated at 4 yuan/m2, and the optical fiber is generally estimated at 8 yuan/meter. For each end of the fiber, an additional material cost of 2,000 yuan (welding, pigtail, etc.) is required.
