Q:What are the advantages of steel structure houses?
With the development of urban construction and the increase of high-rise buildings, the development of steel structure in our country is very fast. As a kind of green environmental protection building, steel structure residence has been listed as the key project by the Ministry of construction. Especially in China's large and medium-sized city, more people and less land resources, and people to the residential density, green environment requirements more and more high, wide range of application of steel structure housing, is China's production of the inevitable result of the development of.
Q:How is the roof of the steel structure closed?
Light steel construction usually need to do edge has the following parts: roof, wall, cornice, corner, wall, door, window, Hupon, and parts of the edge ventilation and lighting. If there is a parapet gable and eaves gutter, then the practice will vary.Before the company's approach to the roof is to use a cover plate to cover both sides of the roof, this approach has the following shortcomings:1) fold the edge of the roof at the site of the need to cut the gap in the field, the construction speed is slow, the quality is not easy to prove;2) the edge plate and the roof plate do not have a reliable connection surface, the connection is not firm, and the utility model is usually connected by an aluminum pulling nail, and is easy to disengage;3) in theory, it relies on the turning at the bottom of the ridge to play the role of expansion, but in fact, it can make the stretching force of the bend long cut the fixed aluminum rivet, so it can not get the telescopic effect at all;
Q:In the installation of steel structure, insulation foil should be placed in the side wall or side wall? Why?
This is just the general case. Basically not strictly required.
Q:Where are welded parts of steel structures to be subjected to nondestructive testing?
The appearance of the weld is smooth and beautiful, and there shall be no welding defects, such as blowhole, undercut, flowing, welding failure, incomplete sealing angle and non sealing.
Q:How much is one ton of steel structure installed?
If the pipe truss, or grid, to 2000-3000 tons of installation costs, depending on the complexity of the structure and the amount of steel to be fixed.
Q:What is the steel structure of portal frame and frame difference
The bent frame is composed of a roof truss (or a roof beam), a column and a foundation, wherein the column is hinged with the roof truss and is rigidly connected with the foundation. It is the basic structure form of the single story factory building.
Q:Ask the two grouting steel structure column anchor bolts for what?
The steel column is the anchor bolt stress, because most of the construction of two pouring simply failed, not what role will the package effect, prevent the anchor bolts under the influence of environment corrosion. If the construction is qualified, should also participate in stress
Q:Can the steel structure workshop be used as the ground lead of lightning rod?
The use of steel bars as lightning protection equipment should comply with the following requirements: 1 buildings should use reinforced concrete roof, beams, columns, steel reinforcement as the base line.
Q:How to detect crack of steel structure quickly and effectively
Crack detection usually adopts the method of magnetic particle inspection, of course, the ray flaw detection method can achieve the same effect, and is more effective for the deeper crack, but the cost is high. Ultrasonic theory can be done, but manual inspection at the scene, the workload is too large, basically impossible to achieve.
Q:How much is steel per square meter of steel foundation?
Generally speaking, the independent base steel content is in 50~60Kg/ cubic concrete.
