Only show for directly understanding the important element of the present invention.

The specific embodiment

Utilize 1 to schematically illustrate a joint strip in Fig. 1, it comprises a bar 2 and a plurality of rib 3, and described rib advantageously is molded on the bar 2.First rib 3 is used to improve water channel and so sealing joints.Rib 3 advantageously has projection 4, and it is used to improve fixing in building and because bigger water circulation is used for sealing.Joint strip uses in known manner, for example is used for the seal operation seam.This is owing to the distribution of building in the concrete segmentation forms, yet wherein the common force closure of each segmentation ground connects, because reinforcement passes each segmentation.Joint strip is made of the PE of PVC-P, PVC/NBR, modification, dissimilar elastic bodys usually.

Present maintenance rib 5 arranged according to the present invention on bar 2, it is used to keep injection hose or other encapsulant such as expansion bar etc.Keep rib 5 to have projection 6 equally in according to the embodiment of Fig. 1, this projection realizes and projection 4 identical functions of rib 3, additionally also is used to block material to be kept.Keep the structure of rib 5 and the diameter with geometry, the particularly flexible pipe of material to be kept or flexible pipe is relevant basically on bar and with respect to the setting of rib 3, but have nothing to do with the type of employed flexible pipe.Can keep injection hose or material arbitrarily by holding device thus.Keep rib 5 advantageously on the whole length of joint strip, to extend, yet also can constitute discontinuously, yet prerequisite is to guarantee reliable maintenance.

Injection hose should have enough cross sections at this for good workability, for processing is firm, injection material should be possible under less pressure from the outflow of hose system under the concrete state of injection, injected system should not be connected with concrete too much, so otherwise may have problems when extruding.

Use a plurality of different systems as injection hose.The PVC inner flexible tube of circle that when injecting concrete, for example has the perforation of dual fabric encapsulation piece, cement paste stops (filtering function) to the adding of the flexible pipe inside meticulous fabric by dual fabric encapsulation piece; PVC inner sleeve circle, that have dual fabric encapsulation piece perforation or fluting, the slit of encapsulation piece and the tap of inner flexible tube biasing ground are provided with; The system that constitutes by plastics or rubber profile semicircle or rectangle with injection channel; The flat hose of the no additional packets sealing of making by PVC of fluting, the flexible pipe slit should close and only open under injection pressure keeping under the pressure of spreading concrete, so that stop the infiltration of cement paste when fluid concrete; Flat hose with a plurality of injection channels, each injection channel can be used for an injection process (multiple injection) individually.Keep rib then suitable with injection hose to be used certainly, yet can keep a plurality of different injected systems by the present invention in principle.

The injection material that can be injected into injection hose for example is cement paste, polyurethane resin or foam, epoxy resin, acrylic resin etc.

Joint strip is shaped and has heteroid maintenance rib in Fig. 2, wherein respectively keeps rib to have a similarly basic geometry basically.Keep rib 5 to correspond essentially to the maintenance rib of Fig. 1, keep rib 7 to compare more longways and far be provided with the rib 3 that is equipped with keeping rib 5.Can realize that thus can reliably keep the injection hose 8 bigger than injection hose 9 by keeping rib 7, this injection hose 9 keeps by keeping rib 5.Usually surely not two injection hose are arranged on the joint strip, yet joint strip allows shown in figure 2, uses the injection hose of different geometries respectively, and need not corresponding replacing joint strip.Certainly also possible when the joint strip of broad is to use the maintenance rib of other geometry, thereby can also keep other different injection hose.

Fig. 3 and Fig. 4 show another possibility, can be equipped with the maintenance rib as joint strip, so that can keep different injection hose.Keep rib 5 and 7 to be arranged side by side, thereby short rib 5 long ribs 7 more closely are positioned on the affiliated rib 3 for this reason.The flexible pipe 9 that then has than minor diameter according to Fig. 4 can be clamped between rib 5 and the rib 3 simply, and aside the maintenance rib 7 of She Zhiing is only born sealing function at this.Have larger-diameter flexible pipe if should use, rib 5 can remove and flexible pipe can keep by means of rib 7 simply so.

In other shape shown in Fig. 5 and Fig. 6 according to maintenance rib of the present invention.Maintenance rib 10, illustrates with respect to the rib 5 that illustrates before in Fig. 5 with respect to angle 11 of rib 3 inclinations at this.Be pulled to rib 10 belows of bending simply according to the present flexible pipe 9 of Fig. 6, and kept by rib.Angle 11 is in this selection like this, makes the flexible pipe maintenance that is fixed, and the maintenance system is uncorrelated with the flexible pipe geometry as far as possible.Illustrate on the right side in Fig. 6, utilize the flexible pipe that also can keep having other geometry fully simply in the system shown in this, because rib 10 is by crooked simply, angle of inclination 11 reduces certainly thus.Although almost vertical with bar at this rib 10, flexible pipe 8 maintenance that is fixed is because rib 10 is defeated on the flexible pipe by means of the returning spring that the bending by rib produces.Keep the accurate geometry of rib 10 therefore must so construct, make and obtain enough returning spring power, and rib 10 can not rupture from bar according to employed 1 material.Keep rib 10 to be similar to and keep rib 5 and 7 to have projection 6, the maintenance that is used to improve.

According to Fig. 7, keep rib 12 also can be arranged on the rib 3, keep rib to realize squarely or with an angle 11, thereby also can be kept reliably in this injection hose.The setting of injection hose and maintenance are similar to Fig. 5 and Fig. 6 setting, yet keep rib 10 to be arranged on the bar 2 at this.Keeping rib 12 to be similar to shown maintenance rib at this has the flexible pipe that projection or those widened sections be used to improve and keeps.

Certainly the invention is not restricted to embodiment shown and that describe.The for example different maintenance ribs that illustrate can make up arbitrarily each other.
