Detailed Description
In order to make the technical problems, technical solutions and advantageous effects to be solved by the present invention more apparent, the present invention is described in detail below with reference to the embodiments. It should be noted that the specific embodiments described herein are only for explaining the present invention and are not used to limit the present invention.
The mechanical interlocking type water stop steel plate structure comprises a subsection water stop steel plate, wherein the subsection water stop steel plate is processed and formed in a factory, only small subsections with the length of 6-9 meters are processed under the transportation condition, the thickness of the steel plate is generally 3mm, U-shaped notches with the width of about 6-10 mm and the depth of about 20-30 mm are punched at the edges of two ends of the subsection water stop steel plate during factory processing, and the U-shaped notches are tooth pits.
The connecting body (c) is mainly characterized in that the connecting body (c) is an integral component and is processed and packaged in a factory; welding and forming by welding seams and nine by using one 4mm thick steel outer sheet plate and two 4mm thick inner sheet plates; a gap with the width of about 3.5-4 mm is reserved between the inner leaf plate and the outer leaf plate to form a connecting groove, and the groove is filled with soft plastic organic structural adhesive and non-cured waterproof material which slowly expands when meeting water, namely the filler; and after the filler is filled in the connecting groove, the connecting groove is sealed by a plastic packaging rubber strip and isolated from the outside.
The inner sheet is mainly characterized in that the bent part of the steel plate is processed into proper wave shape to form wave-shaped teeth, the wave crest height of the wave-shaped teeth is about 2-3 mm, and the wavelength is about 6-10 mm; the bending angle of the steel plate at the corrugated teeth is slightly smaller, so that the connecting groove gap at the corrugated teeth is smaller than the thickness of the sectional water stop steel plate.
The total length of the water stop steel plate in the actual engineering is usually different from several meters to dozens of meters and hundreds of meters, and a plurality of sectional water stop steel plates need to be lengthened to realize the required length. The mechanical interlocking type water stop steel plate structure is an extension technology, a connecting piece can be understood as a socket, and a segmented water stop steel plate can be understood as a plug connector.
When in operation, firstly, the plastic packaging rubber strip (I) on the connecting piece (III) is completely torn off to expose the filler, the segmented water-stopping steel plate (I) is forcibly inserted into the connecting groove at one side of the connecting piece, and the waveform teeth are pressed at the tooth pits to realize mechanical occlusion; at the moment, because the gap between the wave-shaped teeth and the outer leaf plate is smaller than the thickness of the water stop steel plate, the wave-shaped teeth steel plate is tilted, the gap is extruded to be large, the steel plate at the wave-shaped teeth is elastically deformed to generate pressure perpendicular to the surface of the steel plate, the connecting piece tightly holds the segmented water stop steel plate, relative displacement in all directions between the wave-shaped teeth and the segmented water stop steel plate is limited, so that the wave-shaped teeth and the outer leaf plate are meshed into a whole, another segmented water stop steel plate is inserted into the connecting groove at the other side of the connecting piece, and the process is repeated to lengthen the segmented water stop steel plate to the required length.
The sectional water steel plates are matched with the connecting piece and used for realizing the occlusion connection of the left water stop steel plate and the right water stop steel plate; be equipped with the organic structure glue of soft form of moulding in the connecting piece spread groove, non-solidification water and slowly expand waterproof material as packing the seventy degrees, about two stagnant water steel sheets insert the connecting piece and connect the back, pack and to be full of steel sheet, spread groove concatenation department and have irregular surface, hole and clearance, a small amount of packing is extruded and should be cleared up, produces the adhesion simultaneously, with connecting piece and steel sheet bonding together, guarantee that the junction is closely knit not have the cavity, seamless, can make the junction effectively stagnant water, thoroughly prevent the seepage, reach the purpose of stagnant water.
And after concrete is poured, the slowly-expanding material meets free water in the concrete, the slowly-expanding material can generate expansion deformation with the maximum volume of about 1.2-1.5 times, and can fully extrude all irregular surfaces, cavities and gaps of the joint, meanwhile, as the hydration reaction of the concrete is slowed down, the free water is reduced, the strength of the concrete is enhanced, and the filler can fully extrude tiny gaps between the joint and the concrete and generate enough internal stress to thoroughly prevent leakage.
The mechanical interlocking type water stop steel plate structure is processed and formed in a factory and then is transported to a construction site for splicing and installation.
The above description is only for illustrating the implementation process and principle of the mechanical engagement type water stop steel plate structure, and is illustrative and not restrictive, and those skilled in the art can make many forms without inventive work and without departing from the spirit and scope of the utility model, and all modifications directly derived or suggested by the disclosure of the present invention shall fall within the scope of the utility model.
