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:What are the world famous mechanical equipment exhibition?
3, the French international civil engineering and Construction Machinery Exhibition (INTERMAT) the European Construction Committee (CECE), founded in 1988, tenth in 2015, is one of the three famous exhibition of world engineering machinery and construction machinery field, three years. France INTERMAT exhibition exhibits covering mining machinery, earthmoving machinery, concrete machinery, lifting machinery, pavement and compaction machinery, piling machinery, industrial vehicles, pneumatic tools, drilling machinery, building materials machinery, mining machinery and other engineering and construction machinery and spare parts industry. Paris International Construction Machinery Exhibition in Europe - the Middle East - Africa (EMEA) region has a unique position.
Q:Mechanical bearings, all types? Roughly
Spherical roller bearings have two raceways in the inner and outer ring raceways between spherical assembly, a drum shaped roller bearings. The center of curvature of the raceway of the outer race is consistent with the center of the bearing, so it has the same self-aligning function as the self-aligning ball bearing. When the axle and shell are bent, the axial load in two directions can be automatically adjusted. Radial load capacity, suitable for heavy load and impact load. Inner diameter is tapered bore bearings can be installed directly. Or the use of tight sets, the demolition cylinder installed on the cylindrical shaft. The cage uses a steel plate holder, a polyamide forming cage and a copper alloy car holder.
Q:Construction machinery production need to deal with what documents?
The person in charge of the enterprise, the person in charge of the project, full-time safety management personnel in "safety assessment qualified" column content according to the "three persons" Safety Assessment Certificate (fill in the contents of enterprise work safety management staff should meet the enterprise production safety management, the safety management department staff with the qualification to the total contract for not less than 5, not less than 3 professional contracting labor subcontracting, not less than 1; the construction site should be equipped with full-time safety management personnel according to the project size can be determined, according to the construction area of less than 10 thousand M2 project has at least a part-time staff of more than 10 thousand M2; project 1 - 2 full-time staff; more than 50 thousand M2 large sites, according to different professional safety management group);
Q:What is a door rack for a construction site? How high is it generally?
This depends on the erection of the height of the general 3 steps and within 5-6 yuan a meter, assuming the erection of 4.5 meters high, 22.5-27 yuan a square. This is calculated in accordance with single-layer, the higher the more expensive, 9 meters in 65 yuan or so square. In accordance with the establishment of meters, in accordance with the erection of the volume of the calculation.
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 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 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 sub projects of a construction project?
Appendix B Construction Engineering Division (sub branch) engineering, sub project division, B.0.1 Construction Engineering Division (sub branch), engineering, sub projects can be divided into table B.0.1. Table B.0.1 division number of construction works, sub works and sub projects
Q:How are the machine parts stacked?
Then there is a point to note, that is, from there to get used, must be put back where, so that will be organized, all things are owned by you, it will not mess.
