Bamboo springboard: the chief culprit of safety hazards In recent years, with the continuous development of high-rise buildings, the types of scaffolds for building facades have also been constantly innovating, but there has been little change in the springboard, especially in Fujian. The journal correspondent visited Fujian in various construction sites and obtained numerous first-hand information. The bamboo resources in Fujian are relatively abundant, and bamboo scaffolding is basically used for scaffolding on the external walls of buildings. The raw material used in the bamboo springboard is bamboo. The bamboo springboard has great potential safety hazards in its use due to its characteristics such as combustion and vulnerability.
Case 1: March 2, 2011, Nanshan District Xili Honghualing section of the landscape improvement project a wall workers fell from the 4th floor, sent to the Xili People's Hospital died after the rescue was invalid, the cause of the accident is due to bamboo springboard collapse caused Cause tragedy.
Case 2: In the afternoon of June 24, 2008, a fire broke out in the "Beihai Pearl" Meteorological Tower, which is currently under construction in Jiayuguan City, the "China Meteorological Tower". The position of the fire was on the scaffolding outside the tower of the weather tower. The fire was not very great, but the burning position extended from the podium to the height of nearly 80 meters, which made it very difficult to save the fire. The incendiary was a bamboo springboard that was placed on a scaffold. A construction worker informed that the cause of the fire was sparked Mars that ignited the bamboo springboard, and the bamboo springboard further fueled the fire.
It is an indisputable fact that the bamboo springboard has a great potential for safety. The tragedies that occurred in the construction industry in recent years are numerous. Compared to bamboo springboards, steel springboards have obvious advantages in terms of safety performance and economic considerations.
Yuantuo Brand Steel Springboard: Safeguard construction workers' safety, economical benefits, and high investment efficiency. Safety and environmental protection Yuantuo brand steel springboards can be perfectly matched with various types of scaffolds. Scaffolding is also laid on the edge of the erection process. Therefore, whether it is It is safer to use it from the installation process. The use of steel springboards can completely avoid the fire hazards caused by various reasons, and will not help the fire in a fire hazard. The neat appearance of the scaffold after installation can greatly enhance the construction image of the company and highlight the noble sentiments of the construction company and its owner-oriented people and respect for life. In addition, a large number of felling bamboos cause great damage to the vegetation and soil erosion. Therefore, the use of steel springboards has also saved the country’s forest resources, leaving a green hill for future generations. It is an excellent environmental protection product.
The economic benefit is high with the market price. The average price of a bamboo springboard is 12 yuan. Although the one-time cost is low, because the bamboo springboard can only be used for one project, if the use time exceeds one year, it cannot be continued. Use, but analysis from a long-term economic point of view is not cost-effective. The price of a steel springboard is about 68 yuan (210*45*3000). Although the cost of one-time investment is relatively large, the steel springboard can be used continuously for a short period of time. Furthermore, since the middle two steel pipes of the Steel Pipe scaffold using the bamboo springboard as the pedal are only subjected to the construction load transmitted from the bamboo diving board, after the steel springboard is used as the springboard, the two middle steel pipes in the steel pipe scaffold can be saved. It also greatly saves the actual cost of scaffolding. Steel springboards are more economical than bamboo springboards.
Take the medical engineering building of the First Hospital of Putian City as an example. The Medical Technology Building of the First Hospital of Putian City has a building area of ​​27820m2, including the ground floor of l5 floors, a basement floor, a total building height of 67.97M, a length of 60M, and a width of 45M (among them The main building is 16m wide, and the podium below the third floor is 10m wide).
Saving steel pipe analysis: The actual erection area (vertical surface projection) of the external scaffold of this project is 13874m2. When using the bamboo springboard: According to the calculation of the steel pipe used per square meter of scaffolding is about 4.81m, the weight of steel pipe per meter is 3.84kg, the weight of the common steel pipe is 256T, the fastener is used 2.17 per square meter, and the common fastener is 30106; Yuantuo brand steel springboard: about 3.61m of steel pipe used per square meter of scaffolding, sharing steel pipe weight 192t, saving 64 tons of steel pipe, savings rate of 25%: 1.45 fasteners per square meter, shared fasteners In 2011, there were 9998 fasteners saved, and the saving rate was 33%.
Yuantuo brand pedal investment analysis: investment comparison according to 6 meters long scaffolding calculation, the use of bamboo raft 1*1 specifications need 6 total 6*12=72 yuan, need to lay two large crossbar 2*90=180 Yuan, need more than 10 fasteners 10*5=50 yuan. The use of just springboard 3*240 specification requires four pieces total 4*75=300 yuan, 6 pieces of mushroom buckles are needed 6*5=30 yuan, and the initial use of just springboard is more than 300+30-180-72-50=28 Yuan, the initial cost of using a steel springboard for every 6 meters is 28 yuan more.
The above two types of analysis only elaborated the expenditures in one project. More importantly, steel springboards can also be recycled and used for at least six years. However, bamboo springboards can only be used for one year. Furthermore, in the recycling process, bamboo springboards need to be Pens are expensive waste disposal costs, but steel springboards can be sold at a high price of about 2,950 yuan per ton as scrap after 6 years of use.
In summary, the Yuantuo brand steel springboard is slightly higher than the bamboo springboard in individual projects, but the steel springboard is a very cost-effective investment product in the long-term perspective. More importantly, the use of steel springboards has fully demonstrated the responsible and people-oriented glorious image of engineering and construction companies, and has made indelible contributions to leading industry standards and promoting the harmonious and sustainable development of the industry.
