Abstract
The invention discloses a mounting method for an in-built detachable rubber water stop tie, mainly comprising the following steps: fixing a bottom steel plate respectively to the concrete at the two sides of a settlement joint via expansion bolt mechanisms or in the way of welding the steel plate with the inner reinforcing steel bars of the concrete; blocking the gap between the bottom steel plate and the concrete with epoxide resin slip-casting; coating polysulfide rubber on the surface of the settlement joint and the surface of the bottom steel plate; mounting the rubber water stop tie on the bottom steel plate; mounting an upper steel pressure plate and fixing the plate with the rubber water stop tie. The bottom steel plate can be fixed by means of chiseling the concrete until the reinforcing steel bars are exposed and then welding the bottom steel plate to the reinforcing steel bars, or of punching the concrete without reinforcing steel bars, injecting epoxide resin into the punched holes, fixing the expansion bolts in the holes, welding the bottom steel plate to the expansion bolts and at last welding all gaps between the expansion bolts and the bottom steel plate. The mounting method for an in-built detachable rubber water stop tie of the invention has good effect on preventing water seepage and is reliable in mounting the rubber water stop tie, and the mounted rubber water stop tie is easy to replace.
Description
Technical Field
The invention relates to the field of constructional engineering, in particular to a method for installing a rubber water stop for a settlement joint of a building.
Background
The settlement joint between buildings is easy to cause water seepage, and water is generally prevented by embedding a rubber water stop belt in the settlement joint. When the embedded water stop is damaged due to various reasons and causes seam water seepage, the embedded water stop needs to be repaired, and a rubber water stop needs to be installed on the inner surface of the structure again for water prevention.
The general maintenance construction process is to stick the rubber water stop belt to the surface of concrete directly, and then to add a steel pressing plate on the surface, and to screw it up with expansion bolt. Because the surface of the concrete seems to be flat, but actually is not flat, the rubber water stop cannot be completely attached to the concrete, and a gap exists between the rubber water stop and the concrete, so that water leakage is caused, and the aim of completely blocking water cannot be achieved.
Therefore, a new installation method is needed to make the rubber waterstop more resistant to water penetration.
Disclosure of Invention
The invention aims to provide an installation method of a built-in detachable rubber waterstop, which can effectively fasten and seal the rubber waterstop and solve the problem that water leakage can occur after the rubber waterstop is installed.
The method is realized by the following technical scheme:
the construction process features that the bottom steel plate is installed to the surface of concrete, the rubber water stop band is fastened by the bottom steel plate and the upper and lower steel pressing plates, and polysulfide rubber is painted between them. Therefore, the rubber water stop can be effectively fastened and sealed, and the phenomenon that water leakage occurs after the rubber water stop is installed is solved.
The installation and construction process of the built-in detachable rubber waterstop is as follows:
respectively fixing the bottom steel plate on the concrete at two sides of the settlement joint through an expansion bolt mechanism or in a mode of welding with a steel bar in the concrete, and plugging a gap between the bottom steel plate and the concrete by epoxy resin grouting; coating polysulfide rubber on the surface of the settlement joint and the surface of the bottom steel plate, and installing a rubber water stop on the bottom steel plate coated with the polysulfide rubber; and installing an upper steel pressing plate and pressing and fixing the rubber water stop and the upper steel pressing plate by fastening nuts.
The method for fixing the bottom steel plate can be as follows:
(1) chiseling the concrete until the reinforcing steel bars are exposed, and welding the bottom steel plate on the reinforcing steel bars;
or,
(2) punching a hole in the concrete without the steel bar, filling epoxy resin into the hole, and fixing the expansion bolt in the hole; and then, welding and fixing the bottom steel plate on the expansion bolts, and welding and sealing all gaps between the expansion bolts and the bottom steel plate.
In addition, before the polysulfide rubber is coated, water-soluble polyurethane grouting, leakage-stopping quick cement and polyphenyl plastic filler are sequentially injected into the settlement joint.
And fixing the rubber water stop belt and the upper steel plate by using bolts or expansion bolts.
If the rubber water stop is to be replaced, the upper steel pressing plate is detached, the old rubber water stop is taken down, the new rubber water stop is replaced, and the upper steel pressing plate is installed and fixed.
Compared with the prior construction process, the installation method of the built-in detachable rubber waterstop has the characteristic of good water penetration prevention effect, and the rubber waterstop is firmly installed and can be conveniently replaced.
Drawings
FIG. 1 is a schematic view showing the installation of a built-in detachable rubber water stop
1-concrete, 2-settlement joint, 3-polysulfide rubber, 4-rubber waterstop, 5-bottom steel plate, 6-upper pressing steel plate, 7-bolt, 8-expansion bolt, 9-fastening nut, 11-epoxy resin grouting, 12-reinforcing steel bar, 13-hole and 14-epoxy resin cement
Detailed Description
There are reinforcing bars in the concrete on the left side of the settlement joint 2 and no reinforcing bars in the concrete on the right side.
Firstly, water-soluble polyurethane grouting, leakage stoppage double-quick cement and polyphenyl plastic filler are sequentially injected into the settlement joint 2.
Chiseling the concrete on the left side of the settlement joint until the reinforcing steel bars 12 are exposed, and welding the bottom steel plate 5 on the reinforcing steel bars;
if no steel bar is in the concrete on the right side of the settlement joint, a hole 13 is drilled in the concrete, and epoxy cement 14 is filled in the hole to fix the expansion bolt 8. And fixedly welding the bottom steel plate on the expansion bolts, and welding and sealing all gaps between the expansion bolts and the bottom steel plate.
And (3) sealing the gap between the bottom steel plate and the concrete by using epoxy resin grouting 11, and coating polysulfide rubber on the surface of the bottom steel plate and the surface of the joint.
Then the rubber waterstop is arranged on the bottom steel plates at two sides, and then the upper steel pressing plate is arranged. The bolts 7 and the fastening nuts 9 on the left side and the expansion bolts 8 and the fastening nuts 9 on the right side are tightened to fix the rubber water stop and the upper steel pressure plate.
Claims (2)
1. The installation method of the built-in detachable rubber waterstop is characterized by comprising the following steps:
respectively fixing the bottom steel plate on the concrete at two sides of the settlement joint through an expansion bolt mechanism or in a mode of welding with a steel bar in the concrete, and plugging a gap between the bottom steel plate and the concrete by epoxy resin grouting;
