Q:What are the main structures and sub structures in the steel structure?
Briefly, such as a column, a beam, a beam, a braceThe main load-bearing structure of the column, beam and so on is the main structureThe beam, the bracing, etc. are the structures
Q:What is steel structure steel plate?
The penetration welding spot welding, welding should be prepared before the arc welding test pieces, adjust the welding current. Because the floor plate at the bottom of horizontal and vertical supporting formwork, pouring concrete material should not be too concentrated, the plate vibrator timely allocation of vibration.
Q:Why can't epoxy paint be used in outdoor steel structures?
Epoxy paint used as primer, iron red epoxy primer, epoxy zinc primer can be matched with acrylic polyurethane paint, fluorocarbon paint, etc. for outdoor weatherproof coating.
Q:I want to make light steel structure. What tools do I need?
Another major content of the construction of steel structure is welding. The field welding equipment is mainly manual welding. As the labor costs are increasing day by day, in order to improve the efficiency, the gas shielded welding is becoming more and more popular at the installation site. Welding auxiliary equipment is the drying equipment of welding rod: drying machine.
Q:What do we call a steel rivet in the hippocampus? What's the difference between them?
The pull nail of the hippocampus is a kind of metal link with unique structure and high riveting strength. It belongs to new fastening parts. The utility model has good filling hole performance, good air tightness and high riveting strength. The utility model is suitable for riveting fields with high surface requirements, high riveting strength and requirements for sealing performance.
Q:What are the raw materials of steel structure?
In the early stage of steel structure engineering, we should pre bury and embed the steel bar, that is, the anchor bolt. The material of the anchor bolt is Q235B. There are big and small.
Q:Where are welded parts of steel structures to be subjected to nondestructive testing?
All welds shall be full weld, and the weld height shall be in accordance with the drawing design requirements, and the minimum weld angle shall not be lower than the thickness of the sheet to which it is attached. Pay special attention to the welding height at the bottom flange and bracket. Butt welded flange plate to mouth, gouging completely after welding, arc welding lead must be added before the weld shall not be lower than the parent material, and more than high not greater than 2mm, more than high or welding to grinding clearance with grinder. After welding arc plate will lead plane, with grinder will edge polishing.
Q:How can the steel structure be laid with flame retardant PVC pipe?
In the place where the lamp needs to be installed, use the steel wire to bridge and fix the flame retardant PVC {TagsLink:0}. Stand with the wire slot, lay the power or bury the ground.The steel wire laying trough is only available to the upper air inlet
Q:How can the steel structure be divided into Liang Hezhu?
Both have in common is: on the one hand from the perspective of the conceptual design, in the earthquake when they want to appear first in frame beam or beam plastic hinges instead of frame column or shear wall, the so-called "strong column and weak beam" and "strong wall and weak beam"; on the other hand, from the angle of structure, both must meet the seismic structural requirements, specifically to the longitudinal steel frame beams and beams (including steel beam bottom and top beam) must meet the requirements of seismic anchorage length in the anchor into the mount, corresponding to the same level of seismic frame beams and beam stirrup spacing and diameter of encryption area requirements are the same.
Q:How much is the square metre of steel structure engineering cost now?
As we all know, the cost of the steel structure house is basically the same as that of the traditional concrete structure, but the use area can be more than 5%, and the average carbon emission should be about 35% lower. It is an ideal choice for the development of a low carbon economy.Light steel structure residential structure refers to the use of steel structure as load-bearing structure, with environmental protection, light body, energy-saving materials for residential structures. At present, the light steel structure in China's construction industry accounted for less than 5%, while Europe and the United States and Japan developed countries have reached more than 50%. The development of residential steel structure in our country is very large.
