Abstract
(B, ) the utility model discloses a power station seam stagnant water structure, it is equipped with seam provided groove (3) including concrete panel (2) that have seam (1), seam (1) top, and seam provided groove (3) in -connection has rubber bar (4), rubber bar (4) top is provided with arched plastic filler (5), and the top of plastic filler (5) is provided with child base cloth (6), the upper and lower both sides of child base cloth (6) all are provided with polyurea elastomer (7). The utility model discloses an installation rubber bar prevents that water pressure from changing and the destruction of seam deformation to the plastic filler, scatter through setting up the stress branch of child base cloth in with the polyurea elastomer, improve the anti ability of tearing of polyurea elastomer, still bond the plastic filler on concrete panel through child base cloth and polyurea elastomer. The utility model discloses not only can prevent concrete panel's damage, improve structural stability, still have the advantage that the construction portably goes with sealing effect. (B, )
Description
Technical field
the utility model relates to a kind of seam and stops water-stopping structure, particularly a kind of power station joint water stop structure.
Background technology
when there is seam on the concrete slab in power station, need to adopt water-stopping structure butt joint to carry out patching.At present, existing water-stopping structure normally adopts plastic filler pointing seam, then in plastic filler surface coverage antiseepage protective cover sheet, and antiseepage the protective cover sheet expansion bolt made through antirust treatment or stainless steel material and angle steel or band steel are fixed.But the fixed work order of the antiseepage protective cover sheet of this water-stopping structure is more complicated, and need to offer installing hole on concrete slab, damage concrete slab; In addition; the not easily compacting of antiseepage protective cover sheet both sides; expansion bolt comes off in the easy frost heave in fluctuation of water table district of cold district; structural stability is poor; there is the defects such as overlapping the slot between periphery fissure and panel vertical lap seam; not only construction technology is comparatively complicated, and easily forms sealing weak spot, and stagnant water effect is undesirable.
therefore, existing power station joint water stop structure also exists damage concrete slab, structural stability is poor, construction technology is more complicated and stagnant water effect is undesirable problem.
Utility model content
the purpose of this utility model is, provides a kind of power station joint water stop structure.The utility model can not only prevent the damage of concrete slab, improves structural stability, also has easy construction and the good advantage of stagnant water effect.
the technical solution of the utility model: a kind of power station joint water stop structure, comprises the jointed concrete slab of band, is provided with seam preformed groove, is connected with rubber bar in seam preformed groove above seam; Be provided with the plastic filler of arch above rubber bar, the top of plastic filler is provided with tire base cloth; The upper and lower both sides of tire base cloth are provided with polyurea elastomer.
in the joint water stop structure of aforesaid a kind of power station, described in the polyurea elastomer be positioned on the downside of tire base cloth be individual layer polyurea elastomer, the polyurea elastomer be positioned on the upside of tire base cloth is some strata urea elastomers.
compared with prior art, the utility model improves power station joint water stop structure, preventing variation in water pressure and seam deformation to the destruction of plastic filler, improve structural stability and sealing by installing rubber bar; By arranging tire base cloth, the stress dispersion in polyurea elastomer being opened, improving the lear energy of polyurea elastomer, improving structural stability further, thus improve the stability of stagnant water effect and water-stopping structure.Plastic filler is also bonded on concrete slab by tire base cloth and polyurea elastomer by the utility model; eliminate the setting of antiseepage protective cover sheet in traditional water-stopping structure and expansion bolt; not only avoid offering of installing hole, prevent the damage of concrete surface, also facilitate construction.Therefore, the utility model can not only prevent the damage of concrete slab, improves structural stability, also has easy construction and the good advantage of stagnant water effect.
Accompanying drawing explanation
fig. 1 is structural representation of the present utility model.
being labeled as in accompanying drawing: 1-seam, 2-concrete slab, 3-seam preformed groove, 4-rubber bar, 5-plastic filler, 6-tire base cloth, 7-polyurea elastomer.
Detailed description of the invention
below in conjunction with embodiment, the utility model is further described, but not as the foundation limited the utility model.
embodiment.A kind of power station joint water stop structure, is formed as shown in Figure 1, comprises the concrete slab 2 of band seam 1, is provided with seam preformed groove 3, is connected with rubber bar 4 in seam preformed groove 3 above seam 1; Be provided with the plastic filler 5 of arch above rubber bar 4, the top of plastic filler 5 is provided with tire base cloth 6; The upper and lower both sides of tire base cloth 6 are provided with polyurea elastomer 7.
the described polyurea elastomer 7 be positioned on the downside of tire base cloth 6 is individual layer polyurea elastomer, and the polyurea elastomer 7 be positioned on the upside of tire base cloth 5 is some strata urea elastomers.
during installation, rubber bar 4 plug is filled to bottom seam preformed groove 3, then plastic filler 5 pointing is entered seam preformed groove 3, last blade coating polyurea elastomer 7 also pastes tire base cloth 6 in polyurea elastomer 7, is fixed plastic filler 5 by the connection of polyurea elastomer 7 and concrete slab 2; Eliminate the setting of antiseepage protective cover sheet in traditional water-stopping structure and expansion bolt, not only avoid offering of installing hole, prevent the damage of concrete surface 2, also facilitate construction.During use, rubber bar 4 butt joint 1 tentatively seals, and variation in water pressure and seam 1 deformation can be prevented the destruction of plastic filler 5, improves structural stability and sealing; Stress dispersion in polyurea elastomer 7 can be opened by tire base cloth 6, improves the lear energy of polyurea elastomer 7, improves structural stability and sealing further; Thus improve the stability of stagnant water effect and water-stopping structure.And polyurea elastomer 7 itself also has certain sealing and stagnant water effect.
