Abstract
There is provided a method for making glass-fiber reinforced expansion cement and plastic-film composite water-proof layer structure for roofs and its expansion seam structure. The water-proof composite structure for roofs is of plate with a certain size and the expansion seam structure between the plates is of tile-imitation type. Advantage: long service-life, light weight and without leakage source.
Description
The present invention relates to a kind of waterproof technology of roofing for building, especially use water-proof technology for roofing of glass-fiber reinforced expansion cement.
Used waterproof technique in the construction work was divided into flexible water and rigid waterproofing two major types in the past; Flexible water is meant organic flexible waterproof layer made from asphalt felt or other organic waterproof coiled materials, and main drawback is to be subjected to solar radiation that catabiosis easily takes place, and work-ing life is short.Rigid waterproofing then refers to those waterproof plates with brittle concrete or mortar making, and the waterproof layer of using flexible joint material (ointment) to be connected again has the advantage of long service life, but has two fatal weakness simultaneously; First from great, every square metre about 100 kilograms, increases load of buildings greatly; It is easily aging that the second interlocking waterproof plate stitches used ointment, easily forms leak source.
Task of the present invention is for solving the easily aging and rigid concrete waterproof layer of above-mentioned organic flexible waterproof layer from great, the weakness of plate filleting easy to leak.Utilize GREC and organic plastics film composite methods to solve the roof waterproof problem, fundamentally solve the existing deadly defect of above-mentioned two class waterproof techniques.
Content of the present invention comprises: the roof waterproof layer structure of GREC and plastic-film composite and expanded joint structure and making method, the roof waterproof layer composite structure is the plate that certain size is arranged, simulating tile type structure (seeing Fig. 1, shown in Figure 2) is adopted at the expansion joint between the plate; The roof waterproof layer composite structure comprises that original roof construction layer 1(comprises thermal insulation layer), mortar levelling layer 2, plastics film sealing coat 3, GREC layer 4; The simulating tile type expanded joint structure is that branch storehouse stalk 5 is laid in the requirement of pressing board piece size on established estate surface layer 1, and when making the roof waterproof layer plate, two plates are submitted at a minute storehouse stalk 5 and built up the simulating tile type structure; The GREC waterproof layer is made by low basicity expansive cement mortar and glass fibre.
The prescription of low basicity expansive cement mortar is:
Low basicity expansive cement: sand: water: water reducer=1: 0.5～2.5: 0.25～0.55: 0～0.01 glass fibre can be with fiberglass gridding cloth or with the non-twist spun yarn of glass, when making the GREC waterproof layer, as making strongthener with fiberglass gridding cloth, every shop one deck grid cloth, spray one time mortar, determine lapping scrim layer number and sandblast slurry number of times as required, when making strongthener with the non-twist spun yarn of glass fibre, non-twist spun yarn prescinded be mixed in the mortar, be ejected on the plastics film sealing coat 3.
Used plastics film, glass fibre and low basicity expansive cement, water reducer etc. all are the commercially available prod.
Roof waterproof composite structure construction procedure can be referring to accompanying drawing 1～4.
On the basis of original roofing 1, smear the cement sand bed levelling, determine the size of each plate of waterproof layer roofing, carry out branch storehouse stalk 5, pressing board piece size and expansion or contraction joints need paving plastic film sealing coat 3, make GREC waterproof layer 4 again, when making the back plate face mutually, institute's expansion or contraction joints of staying is made and is become the simulating tile type structure between two plates, perform the back screeding and compaction, secondary screeding and compaction after the initial set, screeding and compaction for the third time before the final set, topped, the watering maintenance.
When making GREC waterproof layer 4, as strengthen 1 sand-cement slurry of every shop one deck grid cloth spray with fiberglass gridding cloth, the 3 layers of grid cloth in general shop get final product, when strengthening, spun yarn can be cut off with cutting machine, dispel with pressurized air as the non-twist spun yarn of usefulness glass fibre, in the mortar spray gun, mix with mortar, be sprayed onto on the plastics film sealing coat, deposit to the thickness of requirement, press epimere institute recitation of steps screeding and compaction three times, topped, watering is supported and is raised.
Effect of the present invention is to reach work-ing life more than 10 years, and considerably beyond existing organic flexible waterproof layer, and from heavy and light, specific rigidity concrete roof waterproof layer alleviates 75～80%, and there is not leak source in no ointment filleting, is a kind of ideal waterproof technique.
