Benefit analysis
Economic benefits
The quality problems of the host structure are generally: cracking, mold expansion, sinking, root rot, slab staggering and the like; the processing mode is generally as follows: and (5) polishing and repairing. The statistics is obtained according to the internal condition of the department and the industry consultation: the main structure repair cost is generally 300 yuan/layer, can simply divide according to its repair position, and the broken root of mountain wall wrong platform: structural panel crack =2:1 due to insufficient thickness; the cost of removing the wall column is generally 1200 yuan/layer, can be roughly divided according to the repair area, difficulty and repair probability, the wall column base expands the mould: distortion of the small short-limb shear wall: uneven door opening: uneven wall surface of the shear wall: the top plate is uneven = 3.
From the above information the following analysis can be performed:
gable part
Compared with the traditional process, the process has the advantages that the gable formwork is hung with the thickness of 100mm, the number of embedded screws at the bottom is increased, each embedded screw sleeve is 0.2 yuan, 100 embedded screw sleeves are consumed in each layer, and the screws can be repeatedly used, so that calculation is not carried out.
Compared with the conventional process, the process can save the cost of repairing the embedded sleeve to be avoided by subtracting the cost of the embedded sleeve, namely 200- (0.2 x 100) =180 yuan/layer. The problem that the gable part is not fixed in place is well controlled, so that the cost caused by the fact that the plastering thickness of the outer wall is integrally increased due to the fact that the gable is staggered is avoided, the integrity and the attractiveness of the outer vertical surface of the soil body structure are improved, and the economic benefit and the social benefit are remarkable.
Wall column foot part
Compared with the traditional process, the process adds a circle of locking template, subtracts mortar plugging and reduces the polishing cost by about 300 yuan per layer.
The length of each layer of shear wall is 113.25m, the width of the shear wall is about 12.4m, the lock-up template is made of underground engineering waste templates or leftover materials, the cost is neglected, the templates are repeatedly considered according to 1 layer per 10 layers, and the residual value is 0; the plugging cost of the cement mortar is plugging cross section (simplified into triangle) × 2 × plugging length (wall length + wall width) × mortar unit price =1/2 × 0.05 × 2 (113.25 + 12.4) × 500=157.06 yuan/layer; therefore, the construction method saves 300+157.06=457.06 yuan/layer. And can be fine reduce the concrete waste, reduce the building rubbish and produce, convenient construction.
Small short-limb shear wall
After the small short-limb shear wall is pulled through and reinforced, the deviation problem can be obviously improved, the picking and repairing are avoided, and the cost for manufacturing the communicating screw rod is ignored. Therefore, the cost of the rejecting repair is saved by about 200 yuan/layer.
Flatness of door opening
Wall flatness of shear wall
The adjustment of the flatness of the shear wall surface only reduces the hitting cost by about 300 yuan/layer, so the cost is saved by 300 yuan/layer. And the flatness of the shear wall is improved, and the integral attractiveness is improved.
Flatness of roof
The top plate mainly controls the distance between the first vertical rod and the plate edge to be not more than 300mm, and the secondary die correction is carried out before pouring, so that the disturbance caused by construction is reduced, and no extra cost is increased. The cost is saved by about 100 yuan/layer.
Sheet thickness control
The unit price is about 0.5 yuan/layer by adopting a finished product thickness controller, the extra cost of the finished product thickness controller is 150 x 0.5=75 yuan/layer according to the calculation of using 150 pieces per layer, and the repairing cost of the traditional process is about 100 yuan/layer. So the total cost is saved by =100-75=25 yuan/layer.
In conclusion:
compared with the traditional construction process, the actual measurement achievement system construction method in the stage of improving the main structure saves =180+457+200+300+ 100+25 + 1562 yuan/layer in total, and has remarkable economic benefit.
