Q:The meaning of UT in steel structure
Acceptance specification requirement 100% is primary flaw detection, and level two requires only 20% flaw detection, ut refers to ultrasonic testing.
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:Why can't epoxy paint be used in outdoor steel structures?
Epoxy paint has the advantages of good adhesion, tough film, corrosion resistance, rust resistance and moisture resistance. It is widely used as antirust primer for steel structure and antirust coating for interior steel structure.However, epoxy paint should not be used as a finish coat directly to households
Q:What is the edge of the steel structure?
The main points and methods of construction are as follows:(1) will continue to spread to the roof membrane vertical wall, form a waterproof membrane, flashing a height of not less than 250mm.(2) joints in the roof and the wall of the daughter of vertical handover, mortar leveling layer should be put into a circle or 45 degree slope, brush roll of adhesive, the adhesive sheet density, avoid roll overhead or break, and laying a layer of coil.(3) to receive an flashing coil head fixed on the vertical wall surface coil to prevent decline. The general approach is: cut out a long groove in the vertical wall, reducing coiled material pressed into the groove, and then screw pressure sealing materials filled with waterproof sealing strip, wipe cement mortar protection. The walls on the upper part of the groove shall also be waterproof.Common explanation: flashing refers to the waterproofing roof parapet, cornice or roof wall, its main role is to ensure that the level of the roof cornice and parapet, wall is washed by rain, and the rest of the protection of the roof waterproof layer (not water).
Q:What are the raw materials of steel structure?
Steel column, steel beam, column bottom plate, steel beam connecting plate, column beam connecting plate and so on, the material of these parts should be decided according to the design requirement.
Q:What is called a steel rivet?
It's going to be an antique. Aluminum or steel rivets are used for locking structures when they are used for retaining structures, not for structural purposes. As for the thin steel plate, the steel structure is not good, and at the very least, the structural professional pays little attention to rivet pulling.
Q:How can the steel structure be divided into Liang Hezhu?
The two are not the same, lies in the seismic design, allowing the beam stiffness is greatly reduced, in some cases it can even be allowed to quit the job, but the beam stiffness only allowed to reduce, and not allow it to withdraw from work, so the specification of secondary beam is not resting on the coupling beam however, secondary beams could take on the frame of the. General beam cross height is small (less than 5), with shear transfer, so the specification provides some of the beams and frame beam different in structure, is a requirement of coupling beams is encrypted and frame beam stirrup length can be divided into encryption area and non encrypted area, two is the reinforcement on the beam waist the made clear that "wall horizontal distribution reinforcement should be the waist beams through continuous beam configuration in the range when the beam section height pull; more than 700mm, the two sides of the longitudinal structure of reinforced beam is arranged along the high range (waist band) diameter should not be less than 10mm, the distance should not be greater than 200mm; cross ratio not more than 2.5 of the beam, the longitudinal structure of reinforced beams (on both sides of the waist band) area of the reinforcement ratio should not be less than 0.3%" and will be incorporated into the provisions of a strong, and waist reinforcement in beams as long as the "when the beam web height h W = 450mm, in the two side beams along the height of the longitudinal structure configuration should be reinforced, each side of the vertical reinforcement (not including the upper and lower beam reinforcement and erect steel) 0.1% of the cross-sectional area should not be less than the web section area of bhw, and the distance should be less than 200mm." And not a strong clause.
Q:Brief discussion on safety measures of steel structure installation
Taking into account the safety net suspended after a splash in the welding of Mars is extremely easy to cause the safety net caused by burning fire accident, according to my specific circumstances of the project, installed in the column, the beam column prior contact - bracket welded, fixed pillar, beam installation, the direct use of the bracket as operating platform. Welding type "O" ring at the stigma as seatbelt use. Thus, the utility model has become an economical and practical, convenient and quick safety protection net.
Q:Can the steel structure workshop be used as the ground lead of lightning rod?
The building of the steel beam, steel column, ladder and other metal components and metal curtain wall column should be taken as the lead line, but between the various parts shall be connected through electrical, the copper zinc alloy welding, welding, crimping crimping, sewing, screw or bolt connection; the cross section should be according to the specification in table 5.2.1 the specified value; each metal component can be coated with an insulating material.
Q:How much is the square metre of steel structure engineering cost now?
If only the frame, comprehensive cost at about 1500-1800 yuan / square meters, is a basic frame and a partition, an area of 100 square meters, two floors cost about 300 thousand yuan, and now the cost general steel frame structure cost is relatively close, with the to further optimize the industrial degree and the improvement of building materials, is expected to cost can also be reduced continuously.
