Prefabricated Cement House Eaves

Prefabricated cement house eaves are eaves made from prefabricated cement components, widely used in residential and supporting building projects, with specific design requirements and construction preparation processes.

Engineering Applications

In some residential and supporting building projects with a large total floor area, including multiple multi-story residential buildings and commercial supporting facilities, all building eaves use prefabricated cement components. The total number of components is large, with individual component dimensions ranging from 1.2m to 3.6m in length, 0.3m to 0.6m in width, and 0.12m to 0.18m in thickness, and individual weights ranging from 80kg to 280kg. However, there are length limitations for cement house eaves, with a maximum length not exceeding 1.5 meters. Taking a 4*8-meter cement house as an example, eaves can only be installed on one side at the front and back. There may be special cases regarding the maximum length (the original text '70' may be incorrect).

Design Requirements

Prefabricated cement house eaves must meet architectural appearance decoration needs, possess good waterproofing, anti-permeability, and durability, with a design service life of 50 years, ensuring stability and reliability during long-term use.

Construction Preparation

• Technical Preparation: Organize relevant personnel for drawing review, prepare construction technical disclosure documents, accurately set out and position, and conduct incoming inspection of components to ensure construction accuracy and standardization.
• Material Preparation:
  • Prefabricated Cement Eave Components: Produced by qualified prefabricated component factories, with a concrete strength grade of C30, an anti-permeability grade of P6, a smooth and defect-free surface, dimensional deviations in compliance with standards, and quality certification documents required upon arrival.
  • Connection Materials: Use HRB400-grade steel bars as connecting bars, with diameters ranging from 12mm to 16mm, in compliance with relevant standards; prepare high-strength grouting materials with performance meeting requirements.
  • Waterproofing Materials: Select polymer cement-based waterproof coatings with performance meeting regulations, and prepare waterproof sealants for sealing component joints and nodes.

Price Information

Prices for prefabricated cement eaves vary among manufacturers and specifications. For example, Shandong Sishengrui Building Materials Co., Ltd. offers cement eave boards starting at 18.00 yuan per meter (minimum order of 100 meters); Zheng'en in Baoding, Hebei, supplies eave board plastic molds at 40.00 yuan per meter; and Fuzhou 1.2-centimeter cement fiber board eave ceilings in Huaibei, Anhui, are priced at 51.00 yuan per sheet.
