Abstract
The utility model discloses a slowly water-expansion rubber water-stop strip used for civil engineering and hydraulic engineering, belonging to the rubber product technical field. The utility model comprises a band-shaped lath provided with a central hole and at least one expansion line, and a slow expansion membrane is wrapped outside the expansion line. The slowly water-expansion rubber water-stop strip provided by the utility model solves the problems that the ordinary water-stop strip quickly expands with water to cause the concrete and the expansion line after installing to form a gap which affects the water-stop effect. The utility model can be widely used for various civil engineering and hydraulic engineering which need water-stop.
Description
Technical field
The utility model belongs to the rubber technical field, relates to a kind of slowly water-swellable rubber fastening band in civil engineering, the hydraulic engineering, that include centre bore and at least one expansion line that is used in specifically.
Background technology
In water conservancy and civil works,, generally adopt rubber fastening band in order to reach the purpose of anti-seep water.At present, employed rubber fastening band is generally taked in the centre bore one or both sides one slat gum expansion line to be set at least, and this expansion line has the characteristics that water expands rapidly of meeting, and therefore has good stagnant water effect.But also there are some defectives in use: the first, in the transportation or storage process before installation,, thereby can reduce the sealing performance of rubber fastening band if after being caught in the rain or being immersed in water, expansion line expands rapidly; Second, in the casting concrete process, water in the concrete also can make expansion line expand, sometimes before concrete setting, the expansion line swelling state that reached capacity, after the concrete setting, the moisture that expansion line absorbs is separated out gradually, expansion line just can shrink naturally, forms the slit at the concrete that solidifies between expansion line.So not only reduced the stagnant water effect of waterstop, easily seeped water all the better, leak.
The utility model content
The purpose of this utility model just provide a kind of install and use that Shi Buhui meets that water expands immediately, after the concrete setting and can not form the slowly water-swellable rubber fastening band in slit between expansion line.
For achieving the above object, the technical solution adopted in the utility model is: the slowly water-swellable rubber fastening band, comprise the band shape lath that has centre bore and at least one expansion line, and be enclosed with slow swollen film in the outside of described expansion line.
Its additional technical feature is: described expansion line is fixed in the one or both sides of described band shape lath; Described expansion line is protruding on described band shape lath; Described expansion line is recessed in described band shape lath, and slow swollen film is affixed on the expansion line, with it sealing; Described expansion line is fixed in the two ends of described band shape lath.
Slowly water-swellable rubber fastening band provided by the utility model compared with prior art, have the following advantages: one, be enclosed with slow swollen film in the outside of waterstop expansion line, existence that should slow swollen film can delay expansion line meets water and expands immediately, has avoided after the concrete setting and the generation in slit between expansion line; Its two, be enclosed with slow swollen film in the outside of waterstop expansion line, can avoid in storage and transport process because of being drenched with rain or the inefficacy of expanding of other chance regimen conditions.
Description of drawings
Fig. 1: expansion line is the slowly water-swellable rubber fastening band structural representation of convex;
Fig. 2: expansion line be recessed in band shape lath the structural representation of slowly water-swellable rubber fastening band;
Fig. 3: expansion line is another kind of recessed slowly water-swellable rubber fastening band structural representation in band shape lath;
Fig. 4: two ends have the slowly water-swellable rubber fastening band structural representation of circular expander line.
The specific embodiment
Be described in further details below in conjunction with the structure of drawings and Examples the slowly water-swellable rubber fastening band that the utility model proposed.
As shown in Figure 1, the slowly water-swellable rubber fastening band comprises the band shape lath of being made by elastomeric material 1, centre at this band shape lath 1 is provided with centre bore 2, from centre bore 2 to constituting sealing district 3 termination, two ends, (expansion line can be two or many as required to be fixed with fixedly muscle 4 and expansion line 5 in this sealing district 3, also can be arranged at a side or the two sides of band shape lath), and be enclosed with slow swollen film 6 in the outside of expansion line 5.
Because expansion line 5 is by slow 6 sealed envelope of swollen film, in storage and transport process, even if be caught in the rain or bubble, slow swollen film 6 decomposition also need about 10-15 days, thereby have delayed the time that expansion line 5 contacts with water and be unlikely to reduce the result of use of waterstop.In work progress, because the existence of slow swollen film 6, the time retardation that expansion line 5 contacts with concrete, in the concrete setting process, slow swollen film 6 absorbs the water in the concrete and slowly decomposes, and takes the time, make that the time of concrete setting is consistent with the slow swollen film resolving time, then after the concrete setting, closely contact between concrete and the expansion line 5, do not have again the slit to produce.
The expansion line 5 of slowly water-swellable rubber fastening band provided by the utility model can adopt recessed structure in band shape lath groove 7 as shown in Figure 2, or recessed second kind of structure in band shape lath as shown in Figure 3, also can be the structure that as shown in Figure 4 two ends have circular expander line 8.The shape of slow swollen film 6 and the shape of expansion line 5 are complementary, and promptly expansion line 5 is covered by slow swollen film 6 sealings.
Claims (5)
1, slowly water-swellable rubber fastening band comprises the band shape lath that has centre bore and at least one expansion line, it is characterized in that: be enclosed with slow swollen film in the outside of described expansion line.
2, slowly water-swellable rubber fastening band as claimed in claim 1 is characterized in that: described expansion line is fixed in the one or both sides of described band shape lath.
