A solar collector component construction
Construction of passive solar houses, solar collector components include a direct benefit from the windows, air heater, sun between. The framework of these components is best steel material, to reduce the occlusion of the box fan, solar energy, to maximize the draw to meet the insulation requirements.
     Directly benefit from the installation of windows, air collectors, and other components made of stainless steel embedded parts, connectors, such as non-stainless steel galvanization processing should be done. The connectors on each side at least two, and connection spacing not greater than 400 mm. In order to prevent that during use, due to the window cracks and construction joints caused by cold air infiltration, the gap between the border and the wall full application of sealant to fill embedded dense, smooth surface, free from cracks, packing materials, methods, meet the design requirements. Sash Mounted economic and durable, and good sealing effect of the elastic seal.
Second, the roof construction sequence and construction methods
Passive solar housing surface insulation practice in two forms, a flat roof roofing, and the other is the roof of pitched roof.
A flat roof construction sequence and construction methods
The construction sequence of the flat roof: roof, leveling layer, separated from the gas layer, the insulating layer, to find the slope layer, leveling layer, waterproof layer, protective layer.
Insulation layer is generally used to heat insulation materials (polystyrene foam board) and bulk insulation materials (perlite), the thickness determined according to the local latitude and climatic conditions, the general use of polystyrene foam board thickness of 120 mm or more in the poly l  eveling layer of styrene foam board 600 × 600 mm the configuration Ф6 steel mesh; bulk insulation materials of construction should be located, aerated concrete support pad evenly between the support pads stacked packed in plastic bags sealed bulk insulation material, thickness 180 mm, the support pads capped with a thin concrete slab. Other practices with the same general construction.
Pitched roof construction sequence and construction methods
The pitched roof roofing is a common form of rural passive solar houses. The pitched roof is generally 26 ° -30 °. Usually are ① purlin roof grass-roots structure, Wang Ban, sailing, battens; 2 purlins, rafters, battens; ③ The purline, rafter, reed foil, Mud.
Pitched roof to roof insulation commonly used indoor truss-out scaffolds, truss-out scaffolds, light steel keel hanging gypsum board or acoustic panels suspended wooden PVC board or plywood, sorghum stalks, wiping hemp gray. Insulation materials are polystyrene foam board, bags of perlite, rock wool blankets.
Third, the ground construction methods
Passive solar house floor in addition to the features of a typical home ground, but also with thermal storage and insulation functions, the heat dissipation due to ground less, only about 5% of the total housing cooling, so the sun room on the ground and the ground of ordinary housing slightly different. Its practice in two ways:
An insulating ground method
(1) factors of soil compaction, a layer of linoleum or plastic film to moisture.
(2) Shop 150-200 mm thick dry slag used to insulation.
(3) Shop 300-400 mm thick rubble, broken bricks or gravel is used for thermal storage.
(4) normal ground.
(2) cold ditch
600 mm deep, 400-500 mm wide trench dug around the building foundation, filled with dry slag insulation.
Four, the sun room inspection requirements
Completion and acceptance and the acceptance of the general construction of sun room, similar, to file acceptance, and part of the sub-project is divided into acceptance.
(A) file acceptance
A. The project uses a variety of insulation materials, heat storage materials and components and parts must have a product quality certification, quality inspection reports, the approach of sampling re-examination report card.
Two. Laying on the compound walls, floors and roof insulation material way, pull connected tendons, and other concealed work shall be in strict accordance with the drawings require the construction works records need to do a good job.
3. Check for design changes, if there is, check the design change procedures are complete, the material substitution notice are complete.
4. Check on the construction diary and quality of the project deal with the problem record is complete.
(B) part of the project acceptance
A. Part of the project should be on the process after the end of the acceptance of quality, representatives of project supervision, design, construction and construction units to participate in the inspection personnel. On a process of acceptance after the next process will not be permitted for the next process.
Two. Foundation engineering acceptance should check the insulation works, insulation materials, moisture compliance with design requirements, as well as hidden works records.
3. Ground works should be ground construct hierarchical inspection, construction inspection records should be.
4. The composite wall construction process according to the following intermediate acceptance:
1) the use of insulation materials should have the certificate of origin and re-examination certificate, to confirm the indicators meet the design requirements.
2) The insulation material should be placed closely seamless, such as voids should be filled insulation materials, good construction records.
3) masonry mortar bottom ash full of greater than 80%, to meet more than up to 60% gray, all gray joints shall meet the dense state.
4) construction unit and construction unit should be strictly according to design requirements to do a good job of construction records and quality inspection records, serious archiving.
5) cold bridge site must be handled by the design and construction of units of mutual inspection, identified to meet the design requirements.
