Rubber fastening band is the most frequently used a kind of auxiliary products, utilizes the compressive resistance of rubber and bounce to carry out appropriate design, can form structure sealing system, thus play the effect of sealing, reach the effect of permanent sealing, and play the effect of damping, buffering.Therefore effectively must improve the backward technique of traditional waterstop, improve the water resistance of waterstop, the needs of modern project could be met.For this reason, the multi-function back of development a kind of " good, the environment protection energy-saving efficient of water resistance, attractive in appearance durable in use " paste expanding type rubber waterstop be special timely, be have far-reaching.
Utility model content
The multi-function back that technical problem to be solved in the utility model is to provide one " good, the environment protection energy-saving efficient of water resistance, attractive in appearance durable in use " pastes expanding type rubber waterstop.
The utility model adopts following technical scheme:
A kind of multi-function back pastes expanding type rubber waterstop, comprises rubber water-proof base band, is symmetrically distributed in the expansion sealing strip of described rubber water-proof base band longitudinal centre line both sides and is arranged on the function sealing edge strip of described rubber water-proof base band two avris; Described expansion sealing strip and function sealing edge strip are all arranged on the one side of rubber water-proof base band towards structure upstream face.
As further improvement of the utility model, between the expansion sealing strip and function sealing edge strip of rubber water-proof base band longitudinal centre line homonymy, be provided with reinforcing rib, described reinforcing rib is also arranged on the one side of rubber water-proof base band towards structure upstream face; Form tensile connection plate between expansion sealing strip, between the expansion sealing strip of homonymy and reinforcing rib, form decompression junction plate, between the reinforcing rib of homonymy and function sealing edge strip, form slow pressure junction plate.
Further, described expansion sealing strip is set to extend out arc surfaced, extend out pointed shape or extend out planar shaped.
Good effect of the present utility model is as follows:
The new construction mode that the utility model adopts " plane tension, cambered surface expand ", utilize inclined-plane to extend out, cambered surface connect profile advantage, the pressure produced before making full use of concreting, impels waterstop to form self bounce, can reach sealing effectiveness in various degree.When external water pressure is too large, utilize hydro-expansive rubber, gradually by under the condition of water, increasing pressure by expanding, improve the sealability of waterstop in limited range, the most stable, the most reliable sealing requirement can be reached.
The utility model adopts new technology, the new technology of " main frame is extruded, subsidiary engine compound ", expanded rubber and General Purpose Rubber can be combined with each other in extrusion, an entirety can be formed by microwave vulcanization, the level of processing of rubber industry can be brought up to a new stage, the way of the alternative bonding of energy is bonded at Expandable strip the old technique on waterstop, can reach the target of " industrial upgrading, product renewal ".
