After the problem of Nanhua Commercial Building was dealt with, Zhou Yuan's vacation had already ended, and Chen Qiang continued to live his "single life on weekdays"!

The weather in Luancheng is gradually warming, the difficulty and cycle of concrete maintenance have decreased a lot, and the construction progress on each construction site has been significantly accelerated!

The progress of Nancheng Garden is unusually fast, many buildings have already been capped, and the roof of the last building is ready to pour concrete. According to the usual practice, Mr. Yang took Wu Cheng and Chen Qiang to Nancheng Garden to check the construction quality of roof reinforcement!

Today to check the roof steel bar of Building No. 6 of Nancheng Garden, that is, half a year ago Chen Qiang went down to check the quality of the digging pile for the first time, Chen Qiang felt very amazing and a sense of achievement, feeling that the child he raised was growing up strongly, and today I finally saw him grow up! The construction progress of Building No. 6 is really fast, from Chen Qiang's first time going down the well to the acceptance of the roof reinforcement, a total of only 8 months! It seems that in order to ensure the timely delivery of the house, the South Urban Construction Division is also fighting!

Nancheng Garden Building No. 6 has a total of 33 floors, today's acceptance is the 33rd layer of roof reinforcement, this is a routine supervision and inspection, after the completion of the roof reinforcement construction, the main core project of Building 6 is completed!

The construction elevator of Building 6 of Nancheng Garden is currently only accessible to the 22nd floor, Chen Qiang and they need to climb the outer frame to reach the construction surface of the 33rd floor of the roof steel bar, this kind of thing is generally Wu Cheng and Chen Qiang go up to see it, today Mr. Yang proposed to go up to see it in person!

Mr. Yang took Wu Cheng and Chen Qiang to Lu Defei, designers, supervisors and on-site representatives of Nancheng Real Estate Company together to the roof steel work surface "walked", today there are 11 floors to climb, the vertical height is about 33 meters, the sky is raining lightly, the group is cold and cold when crawling on the outer frame, and the spring of the city is poured back to late winter by a rain!

The outer frame is generally made of steel pipes, a little outer frame tread is composed of two steel pipes, some are composed of one, the handrail is also a steel pipe, the links between the steel pipes are completed by fasteners, and the quality of the general outer frame is good! The outer frame will also be covered with a construction net, and the outer frame between the floors will generally be provided with a fall-proof nylon net, which can not only prevent personnel from falling, but also prevent construction materials from falling and causing safety accidents! The outer frame is generally composed of many cubic structures, and the outer frame ladder shuttles in the cubic structure, and often the position and steps of the ladder are not standard, and it is more difficult to climb than ordinary stairs!

A group of people must wear a helmet when climbing, otherwise it is easy to hit their heads, and it is not an ordinary pain to hit the outer frame! Because of the light rain today, the group also wore construction gloves when climbing to prevent the harvest from being cut and dirty! Even so, climbing up to the roof can still stain your clothes, as some passages can only be passed sideways!

A group of people came to the roof steel construction work surface, a hundred meters from the ground, and there is no closed fence around, especially after climbing eleven floors, the average person is estimated to be scared of the legs, but for people who participate in this kind of work all year round, only the cold of the body, no fear in the heart!

The acceptance of the roof reinforcement is relatively simple, take the construction drawings and check whether the number and specifications of the beam and slab reinforcement are the same! The steel bar of the plate is generally a two-way double-layer steel bar, and it is clear at a glance that the difference in specifications is round steel or cold-rolled rebar! The reinforcement of the beam is more complicated, one should check the anchorage length of the plate reinforcement in the beam, the second is to check the anchorage and lap length of the reinforcement between the beam and the column, and the third is to check the lap of the reinforcement at all corners!

The construction technology and craftsmanship of the South Urban Construction Division are generally guaranteed, especially his full-time team, but it is definitely not possible to be attached to the South China Commercial Building! The acceptance of the roof reinforcement of the sixth building of Nancheng Garden is good, Wu Cheng and Chen Qiang did the inspection and review together accompanied by Lu Defei, supervision and design, the actual situation and construction quality meet the design and specification requirements, and only need to check the internal information to be completed! After listening to the reports of Wu Cheng and Chen Qiang, Mr. Yang decided to return to the conference room for a meeting!

As the order of going upstairs, Mr. Yang was the first to go down, about three floors or so, Mr. Yang was in the middle of the ladder from the 30th to the 29th floor, suddenly a step of the stairs made of steel pipes loosened and fell, plus there was a light rain in the sky, the whole steel ladder was relatively slippery, the slope of the ladder was very steep, Mr. Yang's whole body fell down at once, Mr. Yang's hands supported on the handrails on both sides but did not hold up, the whole body fell directly, fortunately, each layer has a safety net to prevent construction materials from falling, Teacher Yang didn't fall downstairs!

Mr. Yang's elbow and the left side of his head collided with the steel pipe in the process of falling, but fortunately he was wearing a helmet so there was no head injury, and his left hand and elbow were slightly injured. Lu Defei was the first to rush to the bottom of Mr. Yang's falling position, and reached out to pull Mr. Yang at the position closest to Mr. Yang, and at the same time notified the safety officer below to hurry up with the safety rope, Mr. Yang put on the safety rope, Lu Defei fixed the buckle of the safety rope on the concrete pillar, Mr. Yang tightly grasped the nylon rope of the safety net with both hands, and after confirming that he did not continue to fall, Mr. Yang slowly moved in the direction of the steel frame and ladder, although the process was very slow, but finally there was no danger, and he returned to the main passage smoothly!

Wu Cheng and Chen Qiang were frightened when they saw Mr. Yang falling, Mr. Yang has never had a safety problem when he inspected the construction site for so many years, and today he actually fell and it is the construction site of a large enterprise like Nancheng Construction Division, so many people walked by and didn't find a problem when they came up! At this time, no one thought about investigating the reason, only thinking about whether Mr. Yang could return safely!

After Mr. Yang returned to the safe place, he asked Lu Defei to carefully check whether there were any problems with the other outer stairs to prevent similar situations from happening again! Lu Defei arranged for someone to conduct a careful inspection, and after confirming that there was no problem, Lu Defei informed everyone to continue walking! Mr. Yang originally wanted to continue to walk in front, but Lu Defei rushed to the front to lead the way, and the group successfully returned to the conference room of the project department for a meeting, along the way Mr. Yang didn't say anything, Lu Defei didn't know what to talk about, Wu Cheng and Chen Qiang didn't dare to ask anything, even if there were any questions, they had to ask privately in private!

The acceptance meeting went very quickly, and Mr. Yang said one thing separately in the final summary: "The last building of the Nancheng Garden Project was successfully capped, which is gratifying, but the Nancheng Construction Division should add safe and civilized construction, especially high-altitude work, and the safety rope must be tied, and the supervision and construction unit must be carefully checked!" ”

Mr. Yang did not criticize Lu Defei, but Chen Qiang felt that Mr. Yang did not name him and said that it would make Lu Defei more uncomfortable, there was the matter of Nanhua Commercial Building in the past, and then there was the problem of the outer shelf of Nancheng Garden, and the matter of the gathering of migrant workers in Nanyuan in Nancheng also had Lu Defei's figure, and it was difficult for Lu Defei to explain clearly to Mr. Yang!

Teacher Yang may know that it is useless to get angry and question, rather than saying something that is completely useless after venting, it is better not to say it, and see what other moths can come out!

Wu Cheng and Chen Qiang both felt that Teacher Yang was really too angry, if it was the two of them, they would definitely be very angry, Teacher Yang just knocked on the side, such concentration and bearing Chen Qiang and Wu Cheng will take at least about twenty years!

The cause of some accidents is coincidence or accident, and the cause of some accidents you will never figure out, and it may be the best way to solve it if you don't figure it out, so why is it necessary?
