Compared with the concrete structure

Compared with the concrete structure, the steel structure has the following advantages: (1) the steel structure material strength is high, the structure self weight is light Steel structure has high strength. Compared with concrete structure, the cross-section area of steel structure beam and column is sbssteelstructure small, which can increase the effective use area. Generally, the cross-section area of high-rise steel structure column accounts for about 3% of the building area, while the cross-section area of high-rise concrete structure accounts for 7% - 9% of the building area. (2) The construction speed of steel structure is fast. Most components of steel structure are produced in the factory and transported to the site for overall assembly through welding or bolt connection. The steel structure can be used as the construction load of bearing structure to reduce the formwork work during construction, so the cost is reduced and the construction speed is greatly accelerated. The construction speed of steel structure is about 1.5 times that of concrete structure. (3) The layout of pipeline is convenient in the structural space of steel structure. Truss members or hollow members can be used, which makes the layout of pipeline more convenient, and the replacement and repair of pipeline more convenient. However, if the concrete structure is adopted, the beam should not be perforated, and the pipeline generally passes under the beam, thus occupying part of the space. In the case of the same floor height, the floor height of steel structure can be smaller than that of concrete structure, which can reduce the area of peripheral parapet. (4) The environment of steel structure construction is polluted. During the construction of steel structure, sand, stone, soil, cement and other materials are seldom used, so that the flying dust, waste accumulation and noise are avoided from the root woodPollution. (5) The steel structure construction conforms to the sustainable development steel structure manufacturer policy. The steel structure industry is a green package environmental protection construction industry, which is relatively reasonable in the use of resources and energy, and relatively less in the damage to the environment. It is a breakthrough to solve the environmental problems. Steel is a kind of material with high recycling value, and leftovers can be recycled. For buildings of the same scale, the emission of harmful gases during the construction of steel structure is only 65% of that of concrete structure.

the door is a small space

the door is a small space but complex structure component, including door lock, window regulator, horn, anti-collision beam, waterproof layer and sound insulation layer. Sometimes it makes annoying noises. Owners of Buick New Regal need to pay attention to the condition of door hinge, window regulator and other parts, find out the problems in time and repair them. 1. The abnormal sound of the door hinge and limiter of new Regal is because the door is often opened and closed, the door hinge and limiter are vulnerable to wear and tear, and also very easy to produce abnormal noise. If the door is not lubricated in time, it will increase the wear, corrosion and even failure damage. Therefore, it is necessary to keep the door hinge lubricated to reduce the wear degree and open and close the door easily. 2. The abnormal noise of the window lifter and door lock mechanism of new Regal is located in the interior of the door, which is also the part of the door that is prone to pr...
