Description
Technical Field
The utility model relates to a waterproof technical field of building especially relates to a deformation joint waterproof construction.
Background
The underground engineering deformation joint has high hydrostatic pressure bearing capacity. The traditional structure is a medium-buried type, an external type and a detachable type water stop belt, the success rate is not high, and particularly, the medium-buried type water stop belt is in a ten-seam nine-leakage mode; the problems of water and soil inadequacy exist in the Aladdin, the femalescence and the viscose anchor type waterproof belt introduced many years ago, the traditional civil engineering seam remaining process is too rough and cannot achieve at least straightness, and the later one cannot be popularized due to the construction period and the rough construction; for wider seams, the water pressure is high, and the three are not suitable.
The common disadvantages of the first five are: the sealing, seepage-proofing and water-stopping and antistatic pressure both depend on physical extrusion. A gap is formed between the water stop belt and the civil engineering concrete body, and the sealing is reliable without a water-resistant adhesive. Although the deformation joint is mostly contracted and deformed on two sides, the deformation joint also stretches, subsides and even possibly twists (earthquakes). If so, the compressive force at the local gap may be weakened, thereby causing leakage.
The secondary disadvantages are: in order to make the pressure resistance strong, the material is thick and hard, and heavy, therefore, the waterstop is accurately positioned in the dense reinforcing steel bars, and the difficulty is caused. The concrete pouring construction is very careful, and a new process is adopted and practice is carried out when necessary, so that success is possible. In fact, in the engineering practice, the introduced alatin and femaleto compressed sealing bodies are frequently subjected to grooving again and seam correction by adopting special mortar in the domestic engineering practice, so that the effect is achieved. Only one item is needed, the investment is doubled, and the construction period is doubled.
A further disadvantage is the inconvenience of maintenance. Mainly refers to three traditional structures, any maintenance is destructive, and almost all the treatment is temporary and permanent, and finally drainage is mostly performed by drainage or a water receiving tray is arranged to cover leakage. This solution, regardless of the negative consequences of long-term drainage, is not considered a normal maintenance.
The latest anchor-sticking water-stopping system is mostly used on the upstream surface of a top plate and a side wall in engineering practice, and a bottom plate can only be used on the downstream surface, so that the conversion between the upstream surface and the back surface is difficult.
Therefore, there is a need to develop a new technology to solve the above problems.

The following is described in more detail in conjunction with the accompanying drawings:
the structure shown in figure 1 and figure 2 comprises a first concrete plate 20 and a second concrete plate 21 which are used for the top surface, wherein no less than 45kg/m is embedded between the first concrete plate and the second concrete plate3Before the XPS template 4 is used for pouring deformation joints, angle steel 8 is accurately embedded at the upper openings of two sides of the joints, the through length of the angle steel 8 is less than 50 multiplied by 40 multiplied by 4, anchor bars phi 6 and L are 350mm, the positions, the lengths and the arrangement of welding joints are shown in the figure, and the welding joint h is more than or equal to 6. The angle steel 8 should be pre-welded with a threaded screw at a distance of 300. In order to ensure that the screw is perpendicular to the angle steel 8, the angle steel can be screwed in by using screw threads. The screw 7 penetrates out of the back face of the angle steel by no less than 10mm, after calibration, the periphery of the angle steel is fully welded, and the height of a welding line is no less than 10. The longitudinal positions of the angle steels on the two sides of the seam are accurately positioned in a staggered way according to the positions of the screws, such as the sizes shown in the figure. Screw 7 (nominal diameter) M16, total length is about 65, and the clear height of angle steel is 50mm above. The crude hex nut d16, H about 15, S about 30. Rough large gaskets: d16.5, D about 50, S about 60.
The width of the deformation joint is between 30mm and 50 mm; filling butyronitrile foam rubber strips 2 into deformation joints between the first concrete plate 20 and the second concrete plate 21, removing temporary mould strips at the upper ends of the joints before rubber-plastic strip construction, cleaning concrete surfaces, coating permeable epoxy for one time, after drying, applying special water-resistant sealant 3 on two sides, then compressing and plugging the rubber-plastic strips, and uniformly pushing down to be in place to enable the rubber-plastic strips to be arranged on the stripsThe lower two sides are naturally piled up to form colloid. After the strength is reached, special waterproof sealant is applied to the two sides of the upper end of the rubber-plastic strip to strengthen the adhesion. After the sealant is strong, 35 thick sealant is filled in the seam, the width of the sealant is the same as that of the seam, and the sealant is not less than 45kg/m3The XPS slat 1 is protected. Above the XPS protective strip 1, a 3.5 thick stainless steel dowel plate 12 was placed. Narrower than the slit by 8, centrally arranged and longitudinally segmented.
Set up steel pressing plate 9 respectively on first concrete slabs 21 and second concrete slabs 20, steel pressing plate is thick 8mm, sews up the side plane and is the concavo-convex form, as shown in figure 1: at the anchoring part, the steel pressing plate is suspended with a seam edge of 25mm, and at other positions, as shown in figure 2, the steel pressing plate is suspended with a seam edge of 12mm, and a pressing plate seam with the width of 13mm is formed between the two steel pressing plates. The concave-convex shape is designed to disperse the hydrostatic pressure borne by the sealing strip. In order to further prevent the sealing strip from excessively bearing pressure and deforming, a stainless steel force transmission plate 12 with the thickness of 3.5 is designed, and as mentioned above, the plate is thin, does not influence the deformation of the seam, and is enough for dispersing water pressure.

The side wall and the flat top can be provided with no protecting cover. If the ceiling leaks, the ceiling should be opened for maintenance. As temporary emergency, a stainless steel water tray with the thickness of 0.7 can be arranged, and after the water guide hose is connected out, the water guide hose is clamped on anchor bolts at two sides, and the two sides are glued and fixed.
The utility model discloses a structure has following advantage:

The deformation joint is regular, the deformation joint is suitable for multidirectional deformation, the width of the joint is 30-50 mm, and the waterproof and reliable effects are achieved. The back water surface is assembled, the whole process is dry operation, and the installation is easy. Visual inspection can be carried out during operation, and the maintenance is simple and convenient. The chemical sealing not only eliminates gaps and has better sealing effect, but also ensures that the material is softer and is attached along with the gaps, so the requirement on civil engineering is relatively low-the construction of civil engineering nodes is poor, and the improvement is not expected and only can be bypassed. The steel plate pressing not only bears the pressure high, installs and removes conveniently moreover, has avoided destructive maintenance to prolonged entire system's normal life, had obvious sustainability. The new structure abandons the traditional water stop belt structure integrating sealing, water proofing and hydrostatic pressure resistance, so that extremely irregular deformation joints caused by traditional civil engineering construction are avoided, and the nine-joint ten-joint nine-joint theory has the possibility of rewriting.
