The space block of reinforcing steel bar slants little, whole together board go up to see a place placed space block only, and did not use significant step to undertake fixed. Look from whole, colligation of reinforcing steel bar did not open a line, reinforcing steel bar is not flat, and up and down two reinforcing steel bar stagger completely setting, also did not see reinforcing steel bar is maintained child. These problems are small issue, but processing is bad to can cause reinforcing steel bar to show muscle, the phenomenon of floor craze. It is column reinforcing steel bar appears here slant phenomenon, give floor to should continue according to practice column of the standard colligation muscle of at least 3 band, undertake secure and be protectived to column reinforcing steel bar. Better way is to use electric welder to undertake spot welding, such firmer. Person specially assigned for a task also should be arranged to undertake protecting veins that stand out under the skin in the process of beat concrete, mud is versed in work staff also wants to notice finished product is protected. Reinforcing steel bar slants after beat concrete the phenomenon is very serious, the specification does not have pair of column before construction advocate the position of muscle has review a case in which a death sentence has been passed by a lower court. This working procedure is a very important working procedure, cannot careless carelessness. In the process of beat concrete, without arrangement person specially assigned for a task undertakes protective to reinforcing steel bar, bring about the reinforcing steel bar in shaking marvellous beat process to go the phenomenon also is a reason. The sentence that handles program had better be to pass design unit to agree. As construction the person of the same trade of the unit should have encountered such problem. Floor reinforcing steel bar is messy, not complete colligation reachs the designated position. Another reason may be factitious in construction process trample was caused. Want to arrange personnel to undertake farther rehabilitate is perfected after colligation of reinforcing steel bar is finished so, ensure the integral effect of project of reinforcing steel bar. The makings below band muscle is more optional, norms size is differ, the reason is before construction the tell sb one's real intentions to the worker is less than, the construction consciousness of work staff is too poor, too optional. Selecting a very good team and group so is very important thing, a good team and group can save a lot of businesses to project of a construction, on management OK and a lot of more relaxed. The obligate cop of ministry of the foot of a wall shears force too concentration, a section can be formed in wall shears force, cause certain effect to cutting the structural security of force wall. Water and electricity installs all door to should undertake optimizing to the position of cop, reasonable install all sorts of cop equably apart, avoid to be centered in same a position. If be the situation that cannot prevent really,fall, want to undertake be strengtheninged accordingly handling measure to this part. Cut the phenomenon with force metope occurrence rustily reinforcing steel bar, the layer of covering layer mat that main reason holds the reinforcing steel bar when the model in wall shears force namely was not installed reach the designated position, perhaps had not adopted aspirant travel to secure, cause the effect in the because of concrete concussion in concrete beat process and vibrating head, cause covering layer shift or be short of break, reinforcing steel bar stands by pattern plate. The as time elapse after form removal, reinforcing steel bar is divided ceaselessly by the water in air or rainwater, conserve appears with the influence of water rustily, rubiginous mark permeates concrete surface to create such appearance.
