【正文】 ectively , make board shoulder muscle antiabrasion layer cross thick producing cracking. 4, control good sand , stone in a footpath and mud content strictly. The thick sand in the castinplace board should be selected for use, a stone of footpath between , the mud content of grit can39。s shoulder or back, has caused the crack of castinplace board artificially. 3, the crack which the temperature change causes. As everybody knows, the cement condenses and hardens fast at room temperature, the characteristic such as being great of heat of hydration, especially in summer, after the concrete is built, the release amount of the heat of hydration is great, the concrete is under the high temperature, can39。t discover obvious crack, discover the building plank appears crack when the inhabitant repair, past jointly to quality direct the section hurl tell, through step to see on the spot, 16 houses all exist the depth different crack width is between the mms , the great majority of the crack position is placed in plank four Capes, the dynasty sun is more , the Superintendent office of quality concerned, sinking to decline quantity and inclination degree to carry on a reexamination to the house first, result all in allow the scope, again look into construction diagram paper to also match to request concerning the to abovementioned circumstance, pass by hard analytical, the confirmation crack reason has the following what time: 1, cause now main reason of sprinkling the plank crack is the constri ngency of concrete, the concrete is in the nature the hardening the process, because water evaporates continuously, but the physical volume gradual constringency, but the plank is on all sides to be subjected to a stipulation of, can39。s establishing a turn of beam together building plank is togetherwhole to sprinkle, the plank thick 100 mms, concrete mark number is C20, house long about with 8090 ms, don39。 aring end will cause insecurity trouble, but in succession to building quality direct the section hurl tell. Such as once the some city develop a pany to set up 6 layers of floor residence 16 totally, constructing area about 100,000 square meters, the brick mixs structure, the beginning repairs, one steps 2 box off with the brick wall, each one39。s turn to plete work in October,2020, finishing construction acceptance, didn39。t trample or install template and support on it . But developer , for race against time , catch up with progress , or concrete at , congeal and congeal stage after all for the first time still in water at the good castinplace board just, take up the post of purpose to trample, carry the material , concentrate on piling up fragment of brick , mortar , template ,etc.. Premature adding and is carried on one39。 In this course , should maintain the concrete , can39。s Position will be two solid steel bars linked Characteristic: Connect intensity to be high, performance reliable, can bear high stress draw and pigeonhole the load and tired load repeatedly. Easy and simple to handle, construction fast, save energy and material, prehensive economy profitable, this meth
