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:Mechanical bearings, all types? Roughly

The most representative rolling bearings, widely used, can bear radial load and two-way axial load. For high speed and low noise, low vibration occasions with steel dust cover or seal type bearing rubber sealing ring in pre filled with the appropriate amount of grease, the outer ring stopper bearing ring or flange, namely axial positioning, and easy to install in the housing. The size of the maximum load type bearing is the same as that of the standard bearing, but there is a loading groove in the inner and outer rings, which increases the number of balls loaded and improves the rated load.

Q:What is the difference and connection between equipment manufacturing and machine building?

In accordance with the standards of classification, including metal products, general machinery manufacturing, machinery manufacturing, transportation equipment manufacturing, electronic and communication equipment manufacturing industry, electrical machinery and equipment manufacturing, instrumentation and office machinery manufacturing seven deducted 186 small consumer related manufacturing industry after class. Equivalent to the European countries referred to as "capital goods manufacturing", that is, we often say "the production of means of production industry."".

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: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:Changsha Sanlian Building Machinery Fittings Factory

In addition, you can check the input path, or the name of the unit on the map. It will remind you that there is no unit in Changsha and no way. In addition, we received a fax, saying that you want to order what goods, may wish to go to the other party's local industrial and commercial Red Shield network to check whether there is this unit

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 are the main functions of construction equipment monitoring system?

This belongs to information management engineering. The control part is the "heart" and "brain" of the whole system. It is the command center to realize the function of the whole system. The control part is mainly composed of the main console (some systems also have a secondary console). The main function of the total console: video signal amplification and signal distribution, image correction and compensation, image signal and image signal (including switching or voice signals) record, cameras and auxiliary components (such as camera, PTZ, shield) control (remote control) and so on.

Q:What are the safety protection equipment, machinery and equipment, construction machinery and accessories for construction enterprises?

For Turner, fitter, main work gloves, hats, goggles for welder, etc.; there are gloves, shoes cover, goggles, insulated shoes etc.;...... ;
