Embodiment Construction

[0040] The production of the UHPC waterproof layer of the building roof can be divided into five working steps: preparation of UHPC dry mix, on-site mixing of UHPC mix, pouring and paving construction, setting of construction joints, and maintenance:

[0041] 1. Prepare UHPC dry mix in the factory: 1 part of Portland cement, 0.1-0.3 parts of silica fume, 0.1-0.3 parts of mineral admixture, 1.0-1.5 parts of graded sand, 0.003-0.02 parts of shrinkage reducer, 0.002~0.01 part of curing agent and 0.01~0.1 part of water reducing agent are put into the mixer according to the proportion, mixed evenly, and packed for use.

[0042] 2. On-site mixing of UHPC mixture: transport the UHPC dry mixture to the site. First put the UHPC dry mix into the mixer, add water and mix according to the water / glue (total of cement, silica fume and mineral admixture) ratio of 1:0.13~0.22, and add 1.5% by volume after the mixture becomes cohesive ~5% steel fiber, stir evenly and pour out of the machine. ...

Abstract

The invention relates to a permanent waterproof layer of a building roof. The invention adopts ultra-high-performance concrete, and the integral roof waterproof layer is laid in one or more pouring constructions. The obtained waterproof layer body and seams have reliable functions of anti-crack, anti-seepage, waterproof and thermal insulation layer protection, and can simultaneously improve the strength and rigidity of the roof structure. The waterproof layer is durable and long-lasting, and the working life is the same as that of the building. The construction joint bonding joint and strengthening method of the invention can ensure the crack resistance, seepage resistance and waterproof performance of the joint interface. The permanent waterproof layer of the present invention has relatively simple laying and construction, and is suitable for waterproofing and maintenance of new building roofs and old building roofs of different structures, especially for flat roofs with relatively high loads such as planting, water storage, and parking. The waterproof layer of the cement-based composite material with both toughness and rigidity has no aging problem, and the waterproof and seepage-proof reliability of construction joints is high, which can permanently solve the problem of easy leakage of building roofs.

Description

technical field [0001] The invention relates to a building roof permanent waterproof layer material and a construction method, belonging to the technical field of building materials and building construction. Background technique [0002] Roof waterproofing is an essential link in roof construction and an effective way to prevent roof rainwater leakage. The roof panel is usually a reinforced concrete structure. During use, it is affected by natural temperature and dry and wet changes, solar radiation, wind, rain and snow, and indoor cold and heat sources. , and the changing temperature and humidity will cause the inner and outer temperature and humidity differences of the concrete slab. These temperature and humidity deformation and temperature and humidity differences often lead to cracking and water seepage of the concrete roof slab. The construction joints of cast-in-place concrete roof slabs and the joints of prefabricated components are another weak link of waterproof ...
