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:What are the mixing arms of the concrete mixer?

Mixing arm concrete mixer is a component of the mixing arm itself and divided into lateral mixing arm (positive and negative points), stirring arm (also have positive and negative points), stirring arm below is the bearing seat connected, connected with 4 sets of high strength bolts with stirring arm. The top is equipped with wear-resistant mixing blades, connecting with mixing blades, high-strength bolts 2 sets. In addition, some manufacturers have designed mixing side bonded shaft swivel, is installed in the interval between the stirring arm fixed and rotated in two ways.

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

When our company went to the training center of the Department of industrial engineering of Tsinghua University, the professor of Qinghua University told us about it. Equipment manufacturing industry is a general term for the equipment provided for the national economy and national security

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

9. (2) all kinds of cables. (4) either in production or life or attached to the building water pump, cabinet and equipment brought with all equipment, busbar support porcelain ramming material, manufacturing units or commissioned the construction enterprises in the construction site of the factory or production equipment, valves, acid. (2) a variety of metering device, especially the universal controversial problems put forward the principle of classification, dynamic, containers and other equipment, such as mechanical transmission, electrical, ladder, refractory lining, tower, is directly related to the investment, a reasonable division of various air conditioners, socket, heat exchanger, and the telegraph facsimile equipment, perlite, furnace metal embedded parts are the equipment. 7, transportation.

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 is a door rack for a construction site? How high is it generally?

Door scaffolding has not yet unified design and product standards, the products of different specifications, quality is inconsistent. Not only for construction units to use and management of great difficulties, is not conducive to the promotion of applications, but also to the construction safety risks. Therefore, it is necessary to organize and issue a unified standard for door scaffolding

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

3. excavator principle: Excavator through the hydraulic pump to the power of the engine to hydraulic motors, hydraulic cylinders and other executive components, to promote the operation of the device, so as to complete all kinds of operations. Performance: new Isuzu engine, euro II emission, international standards, more into power for you, lower fuel consumption; with high torque rotary mechanism, improve the starting torque of rotary and rotary reducing drift; with a new high efficiency, low noise, large displacement of the main pump, provided high efficiency machine to deal with the bad working conditions; and to strengthen the work of device according to the quarry condition, increase its reliability; strengthen the lengthened crawler frame, while reducing the ground pressure, improve the performance of the fault diagnosis system; new, prolong the overhaul cycle, reduce maintenance cost. Use: 1) building and building foundation excavation; (2) mining soil, stripping mining field covering layer; (3) the quarry, tunnel, underground powerhouse and heap loading operation in the field of material; 4) excavation channel, canal and waterway dredging; (5) replacement of the devices can be pouring lifting and installation, piling, rammed earth etc..

Q:What are the sub projects of a construction project?
