Q:What are the construction materials, components, fittings and equipment in construction?

3. Equipment: a complete device which belongs to the unique function of each function of the construction project. There are systems, equipment and conventional equipment, such as: elevator, automatic fare collection, HVAC, gas fire protection, etc..

Q:Where are the hanging baskets for the building?

It is strictly prohibited to use hanging baskets as vertical transport facilities for personnel and materials; no staff member is allowed to climb from a basket to a B basket

Q:Where are the mechanical pressurization air supply facilities set up?

The purpose of setting up a mechanical pressurization air supply smoke prevention system is to provide evacuation routes and shelters without smoke interference in the event of a fire in the building. Therefore, in the closed door, pressing position, and the fire floor must maintain a certain pressure difference, the position of the air pressure value is a relative positive pressure); at the same time, in the open part of the pressure when the door can have enough air velocity in the opening section, to effectively prevent the intrusion of flue gas, the safety of personnel ensure evacuation and refuge.

Q:What are the principles, performances and uses of the commonly used construction machinery equipment?

1.: concrete pump principle: concrete pump driven by motor pump system, the conveying capacity of constant power control of hydraulic system of concrete pump automatic control, manual control can also be used to select the concrete delivery volume. Performance: 1. using the hydraulic system of double pump double open circuit, the main pump valve swing circuit and S circuit are separate for fault diagnosis and removal; 2. pumping hydraulic circuit adopts the main valve pilot pressure control; 3. hydraulic system has safe relief protection, while the main pumping system overpressure, oil pump automatic pressure cutting off; 4. switching circuit with constant voltage supply with the energy storage device, so as to guarantee reliable swayingforce large and have the advantages of energy saving effect; 5. pumps and valves are used continuously, the world famous brand is more reasonable and more reliable and easily realized commodity concrete transport quantity adjustment; 6. hydraulic pipeline with cone seal pipe joint sealing material; 7. pumping circuit adopts a valve block mode of high and low voltage switch, convenient, no leakage; 8. with oil and oil filter technology, foreign body into the hydraulic system. Further improve the hydraulic system reliability and component life; 9. hydraulic hose hose. Use: widely used in commercial concrete demand for large, high grade and strict quality requirements, long conveying distance of high-rise buildings, municipal construction, electric power, energy, transportation and other civil and industrial buildings, especially the construction of the narrow space more show its true colour of a hero.

Q:What kind of electrical equipment do you have? What are the main components of each device?

1 、 electrical equipment part of electrical equipment mainly refers to: substation and distribution of power equipment and local scattered power, lighting distribution box. Such as: dry type power transformer, high voltage and low voltage power distribution cabinet, control the use of DC cabinet (with battery), standby uninterruptible power supply cabinet, lighting distribution box, power distribution box (cabinet), power factor capacitor compensation cabinet and standby diesel generator etc.. The utility model is characterized in that the rated voltage is mostly 10KV380V/220V by the combination of independent functional electric components, and the voltage is only 24V or 12V in the control system only.

Q:What measures can effectively reduce the construction accident rate?

Hefei construction workers training _ security technology to prevent accidents: prevent the basic starting point of safety accidents is to take measures to restrict energy and dangerous material, to prevent the accidental release. Common safety techniques for preventing accidents are eliminating dangerous sources, limiting energy or dangerous substances, isolating and so on.

Q:What type of industry does the machinery and building accessories processing belong to?

There are only three tax categories in our country: 1 consumption tax, 2 VAT, 3 special tax (agriculture). Therefore, as long as the manufacturing or processing of industrial value added tax on enterprises. It has nothing to do with the economic nature, classification and categories of an enterprise.

Q:What are the main functions of construction equipment monitoring system?

The total of the console cameras and auxiliary equipment (such as camera, PTZ, shield) control generally adopts the bus mode, a control signal to the camera near the terminal in the terminal box decoding, decoding box will total console from the control signal encoding solution, a control action command signal, a variety of actions to go camera control and auxiliary equipment (such as lens zoom, pan rotation etc.). In the case of some cameras that are close to the control center, in order to save money, the command signal, which is the "on or off" signal, can also be sent directly by the console. In short, according to the composition of the system and requirements, can be considered in order to complete the overall console design requirements or order requirements.

Q:What functions should be achieved in mechanical structure design?

The main features of the mechanical structure design are: (1) it is a set of thinking, drawing and calculation (sometimes necessary experiments) in one of the design process, is involved in machinery design, the most specific, the largest volume of work, in the whole process of mechanical design, an average of about 80% of the time for the structure design plays an important role in the success of mechanical design. (2) the multi solution of mechanical structure design, that is, the mechanical structure that satisfies the same design requirement, is not the only one. (3) the mechanical structure design stage is a very active design link, often needs to cross repeatedly. Therefore, in the design of mechanical structure, it is necessary to understand the basic requirements of the mechanical structure from the whole of the machine

Q:What are the sectors of machine building and parts processing?

Industry to classify, it is not very strict. For example, the insurance industry, mining, energy, food, hotels, real estate services industry, garment industry, advertising industry, aerospace, aviation, chemical, chemical, construction, health care, education, training, computer, metal smelting, fire, police, soldiers, accounting, beauty, body, media, publishing, wood, paper retail, wholesale, agriculture, tourism, justice, lawyers, sports, sports, arts, entertainment, medical, art, design, banking, finance, Internet, music, dance, postal, courier, transport, consulting services.
