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

: construction engineering materials, components, fittings, equipment, each refers to: 1, engineering materials: engineering materials mainly refers to raw materials. Such as: sand, stone, steel, etc., there is no processing materials. 2, structural parts: the main structure here is the main structure of the building, the two structure and other accessories. Most of the semi-finished products and the structure of part of the installation accessories, such as: beam beam, continuous beam, beam, beam, cantilever beam, curved beam; steel, timber, concrete beam.

Q:How are buildings, installations and materials divided?

Provisions on the division of equipment and materials for engineering construction? [answer] the division of equipment and materials in engineering construction is directly related to the reasonable division of investment structure, budget preparation and calculation of construction output value. In order to reasonably determine the project cost, strengthen the investment in the process of construction and management, the equipment and materials in the engineering construction is unclear, especially the universal controversial common problems and put forward the principle of division of fifteen copies of "national unified installation project budget quota" of the equipment and materials are divided, the provinces, autonomous regions and municipalities directly under the central government and the relevant departments of the State Council, the Department should be combined with the local situation, formulate rules for its implementation, and report to the Ministry of construction for the record.

Q:What are the world famous mechanical equipment exhibition?

2 、 Las Vegas Construction Machinery Exhibition (Conexpo-Con/Agg) sponsored by the American equipment manufacturers association, the American precast concrete association, the United States sand association. It is the world's second largest construction machinery exhibition after BAUMA. The exhibition, sponsored by the American Association of equipment manufacturers, has been held every three years for nearly a hundred years. The next exhibition will be held on March 2017 7-11. The exhibition is of great size and numerous merchants. It has focused on world famous brands such as Caterpillar, Komatsu, Liebherr and Volvo.

Q:What are the details of construction machinery parts in sand casting?

(1) all kinds of equipment and equipment with the arrival of the body parts, as equipment and components, gas pipelines and accessories such as materials, power capacitors on the construction equipment and materials division rules, various electric fans and electrolyzer etc.. 1, high voltage circuit breaker, platform, shortwave communication equipment and shortwave TV antenna device, natural white afrodite, chemical equipment parts, recycling. For the completion of the building, elevator rails are materials, catalyst, screen (including the box and the instrument has been installed in place, by the design unit to provide manufacturing drawings, unit combination instrument, strengthen the investment in the process of construction and management, and other accessories are materials; non standard equipment, sliding contact line

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 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:The building electrical iron pipe and the pipe line fixing member connected to what is called, what is called the iron pipe and the 86 fixed part of tin

Pipe or direct protection, construction of special operation personnel of construction electrician training materials, focus on the "construction of special operations personnel management regulations", "construction of special operations personnel safety technology assessment program (Trial)", "construction of special operations personnel safety operation skills examination standard (Trial)" and other relevant provisions safety, technical knowledge and skills to master for construction electricians were explained, the book has 10 chapters, including: basic knowledge, common low-voltage electrical appliances and Motor City, power supply and grounding earthing protection system.

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

The function of the mechanical structure is mainly realized by the geometry of the machine parts and the relative position between the parts. The geometry of a part is made up of its surface, and a part usually has a number of surfaces, some of which are in direct contact with the surface of other parts, and this part of the surface is referred to as the functional surface. The connecting part between the functional surfaces is called the join surface

Q:What are the mechanical drawing software?

Personally, CAD is suitable for large machines or buildings, and CAXA is the real machine industry's universal software, and can also save drawings in various formats.
