- 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 kind of electrical equipment do you have? What are the main components of each device?
- Electrical equipment, electrical parts, electrical equipment, electrical components: mainly refers to other construction equipment matching, power driven, electrical heating, electrical lighting, and other direct consumption of electricity and into other parts of energy. Such as: motor and electric heater and start control equipment, decorative lighting lamps and the switch socket, television communication and intelligent engineering for power supply and transformation or environmental protection dust and kitchen fume and other special DC power supply etc.
- Q:Where are the hanging baskets for the building?
- It is forbidden to take a stool or put a ladder on a hanging basket to work higher; it is not allowed to work alone in a basket, and no electric machinery or equipment can be placed in the basket;
- 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

- 1., industry generally refers to its production of similar products, or with the same process, or to provide similar labor services division of economic activities, categories.
- Q:How do the welding parts in the welding drawings of the machine parts indicate the technical requirements of the drawings?
- Therefore, the medium carbon steel has the most extensive application in the medium strength level. Besides being used as building material, it is widely used in the manufacture of various mechanical parts. Welding: 1 the preheating is conducive to reducing carbon steel heat affected zone is the most
- Q:What are the mechanical drawing software?
- The 3D map only contact with SolidWords and Pro/E, Pro/E is better than Solidwords in general, but Solidwords is very simple to use, see Help tutorials you can learn to draw a three-dimensional map is not particularly complex easily to estimate a few days is enough. But any one of the two kinds of software, want to do not understand the words, expert advice is not really easy. UG and MasterCAM haven't touched much, but I've heard that it's suitable for processing stereogram.
