How much is the construction cost of self-built houses in rural areas of Hebei? What should be paid attention to in construction?

Li Jianlizhu, Hebei, majoring in construction in Shijiazhuang, will answer your questions.

First, the cost and budget of rural self-built houses

1. Pile foundation engineering: 100 Yuan/m2.

2. Reinforcement: 45kg/ m2, and the price is usually 160 yuan/m2.

3. Concrete: 0.3-0.5 cubic meters per square meter, and the price is usually per square meter 165 yuan.

4. Masonry works: 120 yuan /m2 (high multi-storey content and low high-rise content).

5. Indoor installation works (including fire fighting): 120 yuan/square meter (according to the grade of the house, multi-storey buildings are relatively low. )

6. Roofing works: 15 yuan/m2.

7. Doors and windows (generally excluding entrance doors) are usually 150 yuan/m2. For high-grade aluminum alloy doors and windows, the price is usually in 300 yuan/square meter.

Second, matters needing attention in rural residential construction

1, foundation treatment

The foundation treatment of rural self-built houses mainly needs to pay attention to moisture-proof and waterproof problems in order to keep indoor dry, refreshing, comfortable and clean.

2, the difference between constructional column and frame column

Structural columns and frame columns are both reinforced concrete columns. Many people don't understand the difference between the two, and then they are fooled by the construction team and can't reach the solid residence they want.

3. Thickness and reinforcement of cast-in-place floor slab

Generally, the floor thickness should be greater than 10cm, and the reinforcement should be arranged in two layers: the bottom reinforcement and the surface reinforcement mesh. The rebar spacing should be within 15cm. However, the floor thickness of many rural self-built houses is less than 10cm, and there is only one layer of steel bars. This problem cannot be ignored.

4, wall masonry

Whether it is block or red brick, there are holes left by scaffolding Rachel on the outer wall of rural self-built houses. When painting the wall, the holes must be blocked with bricks and stones first, and then plastered with nets, otherwise it is easy to seep.

5, simply supported beam and frame beam reinforcement

According to the stress characteristics, when the reinforcement of simply supported beam is arranged, its longitudinal stress reinforcement is placed below. However, the longitudinal reinforcement of the frame beam is placed in the upper part in the bearing position and in the lower part in the mid-span position, which must not be confused. Otherwise, it will not only waste its materials, but also bring potential safety hazards to construction workers.

6. Pay attention to the installation of doors and windows

The doors and windows of the house must be installed vertically, and the plastering on both sides of the hole should be vertical. The gap between the door and window frame and the wall should be filled with efficient thermal insulation materials, such as polyurethane foam or polyethylene foam, and then sealed from the inside and outside with caulking sealant to reduce cracking and air leakage.
