Description
Technical field
The present invention relates to a kind of concrete paving and structural construction premoulded expansion joint filler and preparation method thereof,
It is mainly used in building field.
Background technology
Expansion joint is an important component part of fabric structure, and its main purpose arranged is to adapt to
The reason such as variations in temperature and inhomogeneous settlement of ground and the deformation that causes, build especially for cement concrete
Thing, arranges expansion joint and just seems more important.Owing to cement concrete etc. can produce necessarily in hardening process
Contraction distortion, and the temperature rise that causes of hardening, also lead to expand and shrink, add and become in ambient temperature
Change and under External Force Acting, it will cause plate interiors to produce stress and cause the destruction of plate.In order to avoid these
Problem, presets seam between cement concrete structure at a certain distance so that concrete slab can be the most swollen
Contracting, thus effectively reduce the intralaminar part stress produced because of variations in temperature, External Force Acting, it is to avoid the destruction of plate.
Therefore, the setting at building expansion joint, for ensureing structural safety and the operation of building, has particularly significant
Meaning.
Cork Expansion Joint filler is to abound with the oak bark (cork) in Qinling Mountain Areas, size-reduced, screening, vertical
Pure granulated cork obtained by selecting crude drugs with winnower and horizontal selecting crude drugs with winnower, as aggregate, mixes with the polyurethane glue of special formulation
(this brood lac acidproof, alkaline-resisting, water-fast, oil resistant, resistance to go mouldy, ageing-resistant and endurance, can cementing various metals
With nonmetal, have the biggest cementing strength, and a flexible and percentage elongation of 400%, use temperature be 1～
150 DEG C), curing molding under certain pressure and temperature, then formed by microtome, have excellent can
Compressibility, show as material by compression after volume diminish accordingly, during compression lateral without or seldom have expansion (lateral
Flowing), after pressure eliminates, material can resile.
But cork Expansion Joint filler is high to the requirement of raw material, complicated process of preparation does not utilize and pushes away on a large scale
Extensively.
Joint filler (expansion joint plate) is in addition to the soft art of resin type, and the most conventional also has；(the China fir of softwood without knot
Batten), foam rubber, rattan or cork asphalt felt, Colophonium agate forms fat and glass mat conjugate etc..
Soft plank (Lignum seu Ramulus Cunninghamiae Lanceolatae), compressibility is very poor, not corrosion resistant, need to use tar, and Colophonium makees preservative treatment, dirty
Dye environment, China's timber resources is in short supply, and price is also rising steadily, and volume recovery is low, and actually used price surpasses
Cross cork.
Foam rubber: standard regulation density is more than 0.48, and therefore computed price is higher than cork Expansion Joint filler 2
More than Bei, and China's synthetic rubber more than half rely on into, unsuitable large-scale popularization, moreover aging speed also than
Cork is fast.
Colophonium class material: without compressibility, hot plastic flow, chill crisp, hot day easily drapes over one's shoulders extrusion and takes away, cold day
Cement pavement shrinks and easily causes gap, rainwater, and sandstone easily invades.For making up the Incoercibility of Colophonium, because of
This, foreign standard regulation must add the elastic and compressibilities such as rattan, granulated cork, rubber grain, asbestos
Material, in order to overcome the rheological characteristic of Colophonium, it is necessary to the in addition double-deck wrapping such as glass mat or asphalt felt
With solid shape, complex process, sanitary condition is poor, and compressibility is the least.
