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:China mechanical net

There are mechanical product development and design, mechanical equipment transformation, mechanical equipment maintenance, data inquiries, standard inquiries, mechanical professional translation, mechanical CAD and other mechanical and technical services.

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

Lighting distribution box and other small appliances, slot box, detection control device, air inlet, bell, industrial TV, muffler and its components, dust removal equipment, and the communication line at the same time, a combination of the components installed. (4) refractory used for masonry at site.

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

2.: Principle: loader loader work, powered by a flywheel of the diesel engine to the hydraulic torque converter, the torque converter will drive to the gearbox, and before and after the output flange of the gearbox, the power output of the gearbox after the transmission shaft are respectively transmitted to the front and back drive axle to drive the wheels forward. Performance: 1) Central articulated frame, turning radius is small, flexible and convenient operation in narrow space; 2) using hydraulic mechanical transmission, according to the size of the external resistance and automatic stepless speed change, which can make full use of engine power, and improve the maneuverability, simplifies the loader operation. Is to protect the transmission parts and engine; 3) adopts full hydraulic steering, power shift transmission, hydraulic or flexible manipulation, portable and flexible machine; 4) stable and reliable operation; wide use of low-pressure off-road tires, rear axle swing, with good cross-country performance and through the performance by 5); gas cap oil disc brake system and brake foot up, emergency braking system, the braking performance is safe and reliable; 6) with advanced structure and bright cab. The air conditioning system operates more comfortably. Uses: loaders are mainly used for shovel, loading, unloading, transport of soil and stone a kind of bulk materials, rock and hard soil can also be slightly shovel operations.

Q:Building materials, equipment, components and fittings products must have "three certificates" is what cards?

Three is a business license, certificate of product quality, product quality inspection certificate. Business license is the legal provisions of some industries must be licensed, and handled by the competent department of the operating permit, such as tobacco monopoly license, drug business license, business license and other dangerous chemicals.

Q:Changsha Sanlian Building Machinery Fittings Factory

The company in Changsha Hongdun business online can not find, provided by his address: two Changsha section of Xingsha Economic Development Zone Yuan Ming Road, I checked 114 specially call 12580 to booking the hotel near the road, not the road. Definitely a liar.

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

The design of mechanical structure is based on the overall design, according to the principle of the program to determine and draw a specific structure, in order to reflect the required functions. Is the working principle of the abstract concrete into some parts, the specific content in determining the structure of the material, shape, size, tolerance, heat treatment and surface conditions at the same time, we must consider the process, strength, stiffness, accuracy, and other parts of the relationship between each other and other issues. So, the direct product structure design is the technical drawings, but the design work is not a simple mechanical drawing, drawing only express design language, specific integrated technology is the basic content of structural design.

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

3., machinery manufacturing is also a kind of industry, many industries have parts manufacturing, processing links. Therefore, the processing of parts does not belong to a particular industry.

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.
