Information
With the rapid progress of urban and urban construction, new support system materials and construction techniques have emerged, which has enabled the single project project to be comprehensively upgraded and reduced in terms of construction period, cost, safety and civilization. In order to make all the peers fully understand the cost performance of the new wheel-type steel scaffolding and the traditional fastener-type scaffolding, the following comparison is made:
 
1. Speed ​​up the construction period
 
Take the 100m2 square meter housing construction project as an example. The traditional fastener-type formwork support frame is calculated according to the 8-hour working time per day. It takes 1.5 days or 12 hours (requires 8 technicians and 4 general workers). The new wheel-type formwork support frame only takes 0.5 days or 4 hours (because the wheel-type formwork support system does not need to be time-consuming and labor-intensive to tighten the fasteners; it only needs to be installed directly, right The requirements of the workers are not high, only one technical worker is required to have 8 general workers. Calculated by the now popular four-story four-family residential building: one unit is about 320m2, the traditional one requires 4.8 days, the new one requires 3.2 days, and the first is 1.6 days. The total construction period is 41.6 days faster with a 26-storey residential building.
 
2, a layer of cost savings
 
a: Manual: The traditional fastener-type support frame is calculated according to the above construction period: (8 technicians * 250 yuan / work day + 4 handy workers * 130 yuan / work day) = 2520.00 yuan. The new type of wheel-type support frame is calculated according to the above construction period: (1*250 yuan/piece of workday +8*130 yuan/piece of workday)*0.5=645.00 yuan.
 
b: Material: 1. Traditional fastener steel pipe: 320m2*3.8m*0.008 yuan/m (daily)=9.73 yuan; fasteners: 320m2*3*0.007 yuan/piece (daily)=6.72 yuan.
 
2, the new type of wheeled steel pipe
 
320m2*3m*0.02 yuan/m (daily) = 19.20 yuan. Two comparisons: (9.73 + 6.72) - 19.20 = - 2.75 yuan. By calculating and analyzing one layer, labor costs can be saved by 1875.00 yuan, and material costs can be increased by 2.75 yuan.
 
3. Analysis from the invisible cost
 
The loss of traditional scaffolding fasteners is large; it is easy to lose; the maintenance volume is large, and the maintenance cost is high; the new type of wheel-type steel pipe has no fasteners, basically no loss, and the maintenance amount is not large. According to the above analysis, the cost of the wheeled frame alone from the material rental is higher than the traditional steel pipe scaffolding. However, the cost is analyzed from the total occupation period. For example, the basement uses a traditional steel pipe scaffolding layer for 28-30 days, and the new wheeled steel pipe scaffold takes 23 days. The calculation result is (steel pipe scaffolding) (9.73+6.72)*30 days=493.5 yuan. (wheeled steel pipe scaffolding) 19.20 * 23 days = 441.6 yuan. The result is 493.5-441.6=51.9 yuan (taking the basement 320m2 as an example, the rental fee is 0.16 yuan per square meter). Add labor cost savings of 1875.00 ÷ 320 = 5.86, comprehensive analysis: 5.86 + 0.16 = 6.02, a total savings of 6.02 / m2 yuan
 
4. Safe and civilized construction
 
The traditional steel pipe scaffolding vertical set spacing needs to be controlled by humans to meet the standard. The wheeled steel pipe scaffolding vertical column spacing setting does not require artificial technology to control it, because it will uniform the length of the crossbar when the manufacturer designs and produces. If it is made, it only needs to be formatted according to the space size to achieve the horizontal and vertical standards. The stability of traditional steel scaffolding requires scissors to control, and the wheeled steel scaffold does not require scissors, because its wheel is stuck in four directions with a horizontal crossbar. From the point of view of civilized construction and material management, traditional fastener-type steel scaffolding requires a large space for material storage, because the steel pipe has a large length and size, and the number of fasteners needs to be invested more in storage. Manual construction can meet the needs of on-site civilized construction. The vertical and horizontal rod dimensions of the wheel-type steel pipe scaffold are designed and produced according to the engineering space size, the size is relatively uniform, the manual input is less in storage, the storage is relatively neat, and the floor space is small.
 
Multifunctional wheeled scaffolding construction introduction
 
First, the introduction of wheeled scaffolding
 
The wheeled scaffold is called the multi-functional wheeled scaffold. It is a new type of building support system derived from the socket type coiled steel tube bracket. Compared with the disc-type steel tube bracket, it has the characteristics of large bearing capacity, fast construction speed, strong stability and easy management.
 
The wheeled scaffolding achieved three firsts in the history of scaffolding development: the “first” realized the steel pipe scaffold without any special locking parts on the structure; the “first” realized no activity on the steel pipe scaffolding Parts; "the first" realized China's independent intellectual property rights to the overall new steel pipe scaffolding. This product has been widely used in roads and bridges, municipal engineering, and is widely used in housing construction.
 
Second, the construction characteristics
 
1. It has reliable two-way self-locking ability;
 
2, without any moving parts;
 
3. It is convenient and convenient to transport, store, erect and dismantle;
 
4. The force performance is reasonable;
 
5, can be freely adjusted;
 
6. Standardized packaging of products;
 
7. Reasonable assembly, its safety and stability are better than bowl-type and superior to door-type scaffolding.
