Does the 22# B I-beam length not need to overlap, local patches can find what standard?
The waist reinforcement rib and anti twisting waist reinforcement structure of two kinds, two kinds of binding position in the beam on both sides (called waist muscle is definitely in the waist) beam waist rib plate is removed with plate thickness, according to the height of your waist reinforcement and stirrup number uniform layout. The waist ribs without plates are evenly arranged on both sides of the beam stirrups according to the height of the stirrups and the number of the ribs. The waist structural reinforcement of the anchor lap and 15d, anti twisting reinforcement anchorage and lap mode and a kind of beam.
2. in the middle of the 1/3 areas overlap, two joints center is not more than 1.3 times, lap length is 100% overlap, more than is 50% lap3. binding of tension or compression of steel bars less than 1.3 overlap length belongs to the same area, as long as more than 1.3 times overlap is not the same area. 500mm is used for mechanical connection of staggered, mechanical connections staggered not only to meet 500mm, but also greater than 35dThe 4. argument is not correct, for example, you know that your iron beam overlap region should be 1/3 in a cross street, under the iron bearing area is close to 1/3 (some four molecules bearing an atlas) in this region have staggered 50% joints (center to center more than 1.3 times the length of lap).
According to the thickness of the section steel and the importance of the component, there are two ways. 1. Align and leave the gap; after welding, weld the plate on the web along the circumference; and then, the butt welding of the web shall be 45 degrees oblique (flange shall not be oblique cut). No matter, the weld should be after checking, and draw the detail construction. 1 on the iron two in the cross 1/3 overlap, the center to the center of the joint length of more than 1.3 times, the length of overlap is 50% stagger, if the center of overlap to the center is not more than 1.3 times, lap length is 100% overlap! The joint area has nothing to do with the construction of the lumbar tendon
You don't know the temperature here said the bar where there is no temperature, upper beam reinforcement, roof panel is generally no upper reinforcement area, consideration of temperature shrinkage cracking and reinforcement plate set temperature, temperature stress and reinforcement lap length of reinforcement and their own Ll
