Prefabricated Cement House Construction Drawings
Currently, there are no directly available complete construction drawings for prefabricated cement houses, but key design points and construction specifications can be understood through relevant reference materials.
Core Parameters of Prefabricated Template Drawings for Cement Mobile Houses:
The template requires extremely high dimensional accuracy, with length errors controlled within ±2mm and width errors within ±1.5mm to ensure tightness during component assembly. The support structure adopts a truss design, capable of withstanding a pressure of 500kg/m², meeting construction load requirements. The connection nodes of the template use a combination of welding and bolts, with weld lengths not less than 50mm and M12 bolts selected for both strength and stability. For surface treatment, the template must be polished to a surface roughness of Ra0.8μm and use a 6mm-thick Q235 steel plate as the panel. The main reinforcement consists of HRB400-grade steel bars with a diameter of 12mm, spaced 150mm apart, while the distribution reinforcement uses HPB300-grade steel bars with a diameter of 8mm, spaced 200mm apart, forming a high-strength steel bar framework. The assembly joints are sealed with sealing strips with a Shore hardness of 70 degrees to prevent concrete leakage during pouring; the lifting points are reinforced with 10mm-thick reinforcing plates and clearly marked; drainage holes with a diameter of 50mm are spaced 2m apart to prevent water accumulation in the template; the template must be derusted and painted with two coats of anti-corrosion paint, each with a thickness of not less than 50μm, to extend its service life.
Scope of Application and Construction Points of the 16G906 National Standard Drawing Set:
This drawing set focuses on the construction process of vertical steel bar grout sleeve connections for prefabricated concrete shear wall residential structures. It covers key aspects such as the composition of the structural system, component stacking and finished product protection, lifting and installation processes, cast-in-place joint treatment, and waterproof joint construction for exterior wall panels. For example, components must be stacked on dedicated skids to prevent deformation; before lifting, the component numbers and positions must be verified to ensure accurate installation; cast-in-place joints must be filled with high-strength grout and vibrated densely; exterior wall panel joints must be treated with both waterproof strips and sealant to prevent leakage. The drawing set also provides safety construction requirements, calculation examples, and acceptance record forms, offering standardized guidance for on-site operations.
Extended Suggestions for Construction Drawing Design:
In actual projects, it is necessary to integrate template parameters with prefabricated structural specifications based on building functional requirements. For example, in the design of cement mobile houses, reference can be made to the steel bar configuration and connection methods of the template to optimize wall seismic performance; using the lifting process from the 16G906 drawing set, a component transportation and installation plan can be formulated to ensure construction efficiency and quality.
