Designer

As soon as Qian Xin left in a hurry, there was a gust of wind next to the apprentice's work station, and he disappeared after turning a corner.

Zhao Dongwen was wondering when he saw the fat man who ran out of his office back to his computer and clicked the mouse anxiously. While waiting for the copy, he tapped his fingers on the table in a mess, then rudely tore off the USB flash drive, and shouted when he ran: "Wang!" Chun, give me a computer and take it away."

Liang Qin asked curiously, "What's wrong?"

The fat man strode away without looking back: "The lighting roof of Building 6 seems to have collapsed."

Liang Qin was stunned for a moment, and turned to look up the blueprint, but Zhao Dongwen's heart thumped, and a guilty panic suddenly enveloped him.

Liang Qin wasn't looking at him at all, but Zhao Dongwen couldn't help but confirm it once. Seeing her facing the computer, he quietly clicked on the drawing folder that was sent by mistake.

The folder with a long string of Xs at the end was marked by him based on the experience taught by Qian Xinyi. He found the Liang Tu of Building No. 6 and clicked on it. The horizontal line said 300*600.

He has almost no idea of ​​how much load it can bear, but since the lighting roof has collapsed, his hand holding the mouse trembled uncontrollably, knowing that it must be too small.

Trembling, he switched back and clicked on the correct version, his face turned pale with shock from the marked words, 400*1000.

In the doomsday series of movies, I always like to use the reinforced concrete of the city as the scene. The natural grayscale has a kind of cold desolation, which we often call ruins.

In order to protect the scene for accountability, after the casualties were rescued, the atrium was surrounded by the general contract. When Qian Xinyi stepped on the roof of the 5# house and looked down, he felt this feeling in his heart—the ruins.

The deformed concrete fragments overlapped in disorder, the steel bars were broken and connected in the gaps, the dust that was raised in the sky when the accident happened returned to stability, and the buried blood and tears disappeared without a trace.

Over the years, he has done and seen no less than a hundred projects. The wall fell over and the slab went through, but the situation where the reinforced concrete main beam was pulled off was really the first time Qian Xinyi encountered it.

He was stunned for a long time, still feeling like a clumsy prank.

The girder, which is taller than half a person, is broken by just dozens of large steel pipes that are not even covered with glass. Such a low probability is like a person wearing a hat. It's as outrageous as a broken cervical spine... How is this possible?

The remnants of the beams glued to the roof are indeed a bit thin, and the steel bars can be seen in the section, and there is no suspicion of cutting corners, but even with this small size, the glass is only less than 3 meters long, and the remaining nearly 20 meters are leaks. The empty state, logically speaking, shouldn't be broken like this.

Chen Xi'an had read Fatty's later calculations. Since he didn't mention it, Qian Xinyi believed that Xiao Liang was fine, but his eyelids were twitching, and he felt secretly uneasy.

When the incident happened suddenly, a good old man like Chen Ruihe became a fire-breathing dragon in a hurry. He wanted to find the responsible party before He Jianyun arrived, and suppress the situation to the minimum loss range as quickly as possible.

The general contractor, design institute, and consultants were quickly called to the scene, and then went to the accident site without touching the ground. The relevant construction team waited on the temporary basketball court in front of the meeting room early in the morning, waiting for the holding of the accountability meeting.

Design institutes and consultants who didn't know much were taken to the scene to see the situation and let them know whose problem it was.

After a few months, Fatty didn't remember the size of the main beam at this position when he calculated it. When he saw the small beam, he thought he was 600 high, so he didn't say anything.

The consultant hired by this company is quite professional, but his attention is on the steel beams, because the steel beams belong to the scope of their drawings, but the main structure is not.

After roughly looking around, Chen Ruihe found someone to call them back, and the meeting started with an unprecedented oppressive atmosphere.

Chen Ruihe was obviously furious, he didn't even talk about the scene, and went straight to the point.

"Relevant units have seen it, the lighting roof above the atrium of our Building 6," he sneered, raised his hand and made a wrist downward movement: "It has collapsed! When I received the call, I thought Lao Nie is teasing, me, playing..."

He said the last three words word by word. As soon as he finished speaking, he pressed his palm hard on the table and made a muffled "bang". He was startled, and his face was disgusted.

The fat man turned on the computer, called up the structural plane of the corresponding position, and when he saw it, his eyebrows were curled up. He wanted to tell Qian Xin that there seemed to be something wrong with Liang Gao. He pawed Qian Xinyi under the table with his foot, and then motioned him to look at the picture with his eyes.

As soon as Qian Xin pointed the computer screen at himself, he saw 400*1000 clearly marked on the drawing range adjusted by the fat man at a glance. He slid the mouse to measure it manually, and found that the width was right, and it was still 400.

Qian Xin felt strange, how did the scene become 300*600?

While he was looking at the picture, Chen Ruihe continued with a sullen face: "There are not many companies in China that can do this project like this. If this matter spreads, we don't have to mess around in the industry. Shame! Huh!" The general manager has been exhorting and exhorting, safety first, safety first, is this the safety we promised him?"

"I don't even bother to talk too much. When will the discussion come out and when will the meeting end? I'm very annoyed right now, so try not to let me hear mutual excuses. Yes, no, no. The old rules, start from the design stage, Xinyi, you come first."

As soon as Qian Xin pulled out the power cord, he handed the computer over to him, and faced everyone: "This is the CAD drawing we gave when the site said that it was going to print the blueprint of the process version. The drawing is very clear, and the beam given is 400* 1000, I haven’t laid out the exact size of the beam at the site, but I’m sure it doesn’t match the drawing.”

"I have to raise a question first. The 300*600 beams do exist, but they are the pictures submitted for approval at the very beginning. At that time, Mr. He had not yet decided that the atrium should be sealed with a daylighting roof. He raised the demand in September last year. , when our structure was ±9, we changed the beam section according to the support reaction force proposed by the consultant, and the back is always the girder.”

Chen Ruihe glanced at the date of the folder, it was the version used to post pictures, he nodded, and asked someone to pass the computer to Zhang Hang's bald leader: "Old Nie, what do you want to say?"

Not all leaders are like Qian Xinyi, who will go through the entire drawing because they are worried. Reading the drawing is the work of the subordinates. They control the overall principle and basically know nothing about the details.

Mr. Nie took over the computer and pretended to look at it: "The beam that was broken, we re-wired it. The specific size is 315*611, not counting the reasonable error of the structure. The beam we constructed should be based on 300*600. On the drawing of our design institute, it is indeed a 1000-high girder, but our general contractor will never dare to tamper with the things of the design institute. We must construct according to the drawing, and the construction blueprint is in the archives. You can ask Mr. Chen and our big design institute to review, Xiao Zhang, you can go to the archives and get two sets of drawings."

He didn't show timidity at all, so it can be seen that what he said was not a lie, so the contradiction was immediately aroused, and both sides had their reasons, so whose one was more tenable?

Chen Ruihe is biased towards Qian Xinyi in his heart, educated people are easy to deal with, his thoughts and expressions are clear, and he is more convincing. He has been very happy to cooperate with Qian Xinyi until now, and Qian Xinyi's people His character and sense of responsibility are trustworthy.On the contrary, this bald head is a bit treacherous, boasting in front of him and scolding him behind his back, he is completely clear about the ghost and ghost, and he often digs holes for him during the operation of the project.

Zhang Hang said wait a moment, turned around and lowered his eyes to show a cold sneer, he likes Qian Xinyi's confident look just now, how confident he was in the early stage, when the truth is finally revealed, his expression will change How wonderful, Zhang Hang thought about it for a while, and was full of anticipation for the ending.

Chen Ruihe didn't want to waste time, so he let the discussion continue to scroll down, and rolled to the consultant. He came in a hurry and didn't bring anything. He asked Qian Xinyi to connect to the computer, connect to the wifi on the construction site, and download the email from the mailbox to prove that he At that time, the load submitted to the design institute was 60KN and there was no problem with the connection method of the steel beams.

The ball was kicked to the construction team, several units were in a hurry and began to smear each other, Chen Ruihe made a fuss and asked them to talk about it one by one, but they all promised that it was not their fault, everyone was arguing in full swing, and no one paid attention to it The general contractor technician looking for the blueprint has not come back for a long time.

Because the original file room leaked, the new one was moved to the innermost part of the second-floor board room. Zhang Hang squatted on the steel-plated aisle to call He Jianyun and explained the current situation. He Jianyun asked him about Chen Xi'an Did he come, he said no, He Jianyun asked him to find a way to get Chen Xi'an over.

When Zhang Hang returned to the meeting room, he was empty-handed, and the room was full of dullness. Obviously, there was no breakthrough in the problem. Everyone looked at the person who came in. Zhang Hang said: "The archives are changed, and the materials are very messy. I found the blueprint, but Mr. He just called the general contractor's office and said he would be here in 2 hours."

After conveying the news, he went out to look for diagrams again. Since it doesn't make sense to talk about it, he calculated it and looked at the beam sections of two sizes, which one can be calculated.

There are not many people with structural computing skills on site, one is a fat man, and the other is a technician from the management company. The two of them are equally divided, and it is almost laborious to calculate. In addition, there are so many people staring at each other. The pressure is even greater. slow.

Qian Xin felt anxious when he saw it, so he couldn't help but call Chen Xi'an. The meeting of C Construction Institute just ended there, and he was on his way to send Gao Yuan home. He heard that he would be here in 50 minutes.

Until this time, Qian Xinyi thought that there was nothing wrong with them.
