First, the problems that should be paid attention to in meeting the functional requirements
1, all rooms? Such as bedrooms, living rooms, halls, garages, farm tools depots, grain depots, bathrooms, kitchens, restaurants, stairs, livestock pens, etc. The number of rooms should be sufficient and the relationship between rooms should be appropriate.
2. How big is this room? For example, the minimum area of a single bedroom is not less than 6M2, the minimum area of a double bedroom is not less than 10 M2, and the living room is not less than12m2; There should be no less than 4 kitchens; The length of the solid wall for placing furniture shall not be less than 3M, and the kitchen operation surface shall not be less than 2.1m; The width of the double bedroom should not be less than 3.3M, and the clear height of the bedroom should not be less than 2.4M If the dimensions are not well grasped, it will cause inconvenience for long-term use.
3, according to the principle of quiet partition, clean partition to organize the relationship between the functional rooms.
4, make the main function room (bedroom, living room) have a good orientation, meet the requirements of sunshine, natural lighting and natural ventilation.
According to the lighting requirements, the side window area of bedroom, living room and kitchen should not be less than 1/7 of the ground. According to the ventilation requirements, the openable ventilation window area should not be less than110 ~1/20 of the room floor.
5. If air conditioners are installed, shading and heat insulation shall be carried out according to energy-saving standards.
6. Bedrooms and living rooms should be arranged on the side facing away from the noise flow, and measures should be taken to control the interference of surrounding noise.
7. Paint for interior decoration should contain no harmful substances (such as formaldehyde, benzene, phenol, etc.). ). so as not to harm people.
II. Matters needing attention in meeting safety requirements
1. The foundation should be solid. Before construction, exploration should be carried out, or a pit should be dug for the engineering geologist to confirm the reliability of the foundation. Natural foundation is not afraid of low bearing capacity, but uneven bearing capacity. Reliable measures should be taken according to the actual situation to lay the foundation for the disaster prevention reliability and durability of houses. Special attention should be paid to the prevention of landslides in mountainous areas.
2, the wall should pay special attention to integrity, to prevent collapse in the earthquake disaster. The main method to strengthen the integrity is to select suitable materials, construction methods and structural measures (such as column selection, ring beam and Rachel reinforcement, etc.). ).
The roof should be light, in case it collapses and hurts people during the earthquake. Using wooden frame, steel frame and light slab roof is much better than hanging tiles with reinforced concrete.
4. Non-combustible materials should be used around places with fire sources to prevent the fire from spreading.
5. Building houses in areas where floods and mudslides may occur should be designed according to flood control buildings, with spillway at the lower part and refuge platform at the upper part.
6, should have lightning protection measures.
Three, should pay attention to meet the durability requirements.
1. General rural houses should be designed according to the design service life of 50 years (Category III). If it is easy to replace structural members in structural design, it can also be considered as 25 years (category 2).
2. The seismic fortification category can be considered as Class C .. The earthquake does not collapse, the small earthquake does not crack, and it can be repaired.
3, in order to ensure the durability requirements, the performance of the materials used should be reliable enough, such as the strength of the concrete used should not be lower than C20, reinforcement should not be less than the stress and structural requirements; The steel used should have sufficient tensile strength, yield strength and elongation, and the content of sulfur and phosphorus should be within the allowable range, and counterfeit and shoddy products should not be used. The strength grade of stressed masonry should meet the design requirements, and the mortar strength and block quality must also meet the requirements.
4. Steel embedded parts and embedded wooden bricks shall be properly kept.
5, wooden components should be prepared to prevent termites.
6, close to the fire and high temperature parts should be fire-resistant.
7. The roof should adopt the top of slope as far as possible, and the flat top should have a large slope to ensure the smooth drainage of rainwater.
8, the main components should be easy to maintain.
Four, in order to meet the economic requirements, the following countermeasures can be taken.
1, using local materials;
2. Materials are used properly and are not wasted;
3, do not engage in floral decorations;
4. Use efficient light sources and water-saving appliances.
