Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Example (b): the utility model provides a polymer self-adhesion back of body pastes waterstop, as figure 1 and figure 2, including rectangular shape waterstop body 1 and four convex ribs 2 of setting at 1 upper surface of waterstop body, seted up a plurality of T type grooves 3 on the waterstop body 1, still seted up a plurality of through-holes 5 on the waterstop body 1, through-hole 5 is located between two adjacent T type grooves 3 to link two adjacent T type grooves 3, and the coating of 1 lower surface of waterstop body has from adhesive tape layer 4, and a plurality of T type grooves 3 and through-hole 5 are filled with to self-adhesive tape layer 4. Operating personnel is when the coating of 1 lower surface of waterstop body is from viscose layer 4, will cover 1 lower surface of waterstop body from viscose layer 4 completely, when self-adhesive glue layer 4 pours into a plurality of T type grooves 3 into in, self-adhesive glue layer 4 circulates through-hole 5 between two adjacent T type grooves 3, and fill in full through-hole 5, make and obtain from viscose layer 4 and run through in this body of waterstop 1 completely, will be from viscose layer 4 and the better whole that connects into of waterstop body 1, make self-adhesive glue layer 4 more firm bonding on waterstop body 1. Through 4 firm bonding together with waterstop body 1 and concrete layer from viscose layer to seal the infiltration passageway between waterstop body 1 and the concrete layer, reduced and produced the gap and the infiltration problem that arouses between waterstop body 1 and the concrete layer.
Like figure 1 and figure 2, all filled sponge layer 6 in a plurality of T type groove 3, sponge layer 6 outer peripheral edges and the 3 cell walls in T type groove cooperate, and sponge layer 6 can effective absorption pour into self-adhesive layer 4 in T type groove 3 into, reduces from adhesive layer 4 and has the condition that the bubble produced in T type groove 3 to reinforcing is from adhesive layer 4 at T type inslot 3 cohesive strength. The lower surface of the water stop body 1 is densely provided with the concave 7, and the densely provided concave 7 is beneficial to better adsorption and bonding of the lower surface of the water stop body 1 to the self-adhesive layer 4, so that the glue coating amount of the lower surface of the water stop body 1 is ensured, and the possibility of low bonding strength of the self-adhesive layer 4 caused by too little glue coating amount is reduced. One side of keeping away from waterstop body 1 from viscose layer 4 is provided with barrier film 8, and operating personnel need take off barrier film 8 on viscose layer 4 earlier, paste waterstop body 1 on concrete layer again for waterstop body 1 and concrete layer are firm to be in the same place. The isolating film 8 is arranged to prevent the self-adhesive layers 4 from being adhered to each other in the process of curling, packaging and storing the water stop body 1, so that subsequent construction is influenced; and the problem that the bonding strength of the self-adhesive layer 4 is not high in the subsequent use process due to the fact that the self-adhesive layer 4 is exposed in the external environment for a long time and is wet, damaged or adsorbed with impurities is solved.
As shown in fig. 1, four first trapezoidal grooves 9 are further formed in the water stop body 1, the convex ribs 2 are connected in the first trapezoidal grooves 9 through glue, the protective film 11 is arranged on the upper surface of the water stop body 1 and in the first trapezoidal grooves 9, and the net-shaped stripes 10 are further arranged on the upper surface of the water stop body 1. Operating personnel takes off protection film 11 earlier in the work progress, after laying waterstop body 1 on concrete layer, again with fin 2 from the terminal surface sliding of waterstop body 1 to first dovetail groove 9 in to inject glue in the first dovetail groove 9, make the firm bonding of fin 2 in first dovetail groove 9, finally pour the concrete to waterstop body 1 upper surface. The protection film 11 effectively reduces the possibility that the upper surface of the water stop body 1 is abraded and damaged in the packaging and transportation process of the water stop body 1. The convex rib 2 is detachably connected to the water stop belt body 1, the storage space of the water stop belt bodies 1 stacked together is effectively reduced, and convenience is provided for transportation of the water stop belt bodies 1. When pouring concrete to the upper surface of the water stop body 1, the net-shaped stripes 10 help the upper surface of the water stop body 1 to better adsorb the concrete, and increase the friction force between the upper surface of the water stop body 1 and the concrete so as to facilitate better pouring work.
As shown in fig. 3, one side of the water stop body 1 is provided with a trapezoidal bump 12, the other side is provided with a second trapezoidal groove 13, when two water stop bodies 1 need to be spliced together for use, an operator slides the trapezoidal bump 12 on one of the water stop bodies 1 to be connected into the second trapezoidal groove 13 on the other water stop body 1, so that the trapezoidal bump 12 is clamped with the second trapezoidal groove 13, glue is injected into the second trapezoidal groove 13, the trapezoidal bump 12 is bonded in the second trapezoidal groove 13, and the two water stop bodies 1 are spliced together firmly. But 1 splicing structure's of waterstop body design has played better whole waterproof effect, has improved the flexibility that waterstop body 1 used greatly.
The operation process is as follows: operating personnel need take off from the barrier film 8 on the viscose layer 4 earlier, lay and paste on concrete layer with waterstop body 1 again, make waterstop body 1 and the firm bonding together of concrete layer, then take off protection film 11, slide to first dovetail groove 9 with fin 2 from the terminal surface of waterstop body 1 again, and to pouring glue in first dovetail groove 9, make the firm bonding of fin 2 in first dovetail groove 9, finally pour the concrete to waterstop body 1 upper surface, accomplish the installation.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications of the present embodiment with inventive contribution as required after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.
