Technical Field

[0001] The utility model relates to the technical field of waterproof sealing, in particular to a waterproof sealing structure for a steel support penetrating wall portion. Background Art

[0002] The steel support through-the-wall part refers to the part where the steel support system passes through the wall during construction. The steel support system is mainly used for temporary support and fixation in construction to ensure that the structure remains stable during construction and prevent collapse or deformation. The temporary support system in the steel support system needs to be removed, and the hole through the wall needs to be repaired after removal.

[0003] The existing sealing method is to reserve a circle of water-stopping steel plates at the hole in advance, and then pour concrete on both sides for sealing. However, the construction joints at the junction of new and old concrete are prone to leakage, and once leakage occurs, subsequent repairs will be more troublesome. Therefore, this application proposes a waterproof sealing structure for the steel support through the wall to solve the above problem. Utility Model Content

[0007] A further improvement of the technical solution of the utility model is that the portable disassembly and assembly blocking mechanism includes two blocking pieces that fit the shape of the inner wall of the installation hole, and the two blocking pieces are embedded on the inner wall of the installation hole facing each other.

[0008] A further improvement of the technical solution of the utility model is that both of the two blocking members are made of materials that can undergo elastic deformation.

[0009] A further improvement of the technical solution of the utility model is that a baffle plate is fixedly connected to the inner side of one of the blocking members, and the baffle plate is fixedly connected to the inner side of the other blocking member.

[0010] A further improvement of the technical solution of the utility model is that an annular sealing groove is provided on the inner wall of the installation hole near the reserved plate, and a grouting groove connected to the outer surface of the wall is provided on the inner wall of the annular sealing groove.

[0011] A further improvement of the technical solution of the utility model is that a pipe sleeve is fixedly connected to the inner wall of one of the blocking pieces, a rotating screw is threadedly connected to the inner wall of the pipe sleeve, and one end of the rotating screw is movably connected to the inner wall of the other blocking piece.

[0012] A further improvement of the technical solution of the utility model is that a rotating handle is fixedly connected to the outer surface of the rotating screw.

[0013] A further improvement of the technical solution of the utility model is that: a guide groove is provided at the bottom of the embedded groove, and the guide groove is communicated with the outer side of the wall.

DETAILED DESCRIPTION

[0024] The present invention is further described in detail below in conjunction with the embodiments:

[0025] Example 1

[0026] like Figure 1-6 As shown, the utility model provides a waterproof sealing structure for a steel support through-wall portion, comprising a wall body 1, the wall body 1 being the outer wall of a basement, a mounting hole 2 being opened on the wall body 1, a pre-buried groove 3 being opened in the middle of the mounting hole 2, a reserved plate 4 being fixedly connected to the inner wall of the pre-buried groove 3, a sealing plate 5 being fixedly connected to one side of the reserved plate 4, an outer waterproof plate 6 being integrally cast on the side of the inner wall of the mounting hole 2 close to the sealing plate 5, the outer waterproof plate 6 being a concrete structure integrally cast, a portable disassembly and assembly sealing mechanism being arranged on the side of the inner wall of the mounting hole 2 away from the sealing plate 5, soil needs to be backfilled on the side close to the outer waterproof plate 6, which may come into contact with groundwater and cause leakage, and the outer waterproof plate 6 is arranged with a certain gradient change, by The inner wall of the mounting hole 2 is fitted with the shape of the outer waterproof plate 6. Therefore, the infiltrated water needs a longer infiltration path. The setting of the outer waterproof plate 6 can delay possible infiltration, which is the first waterproof measure. The reserved plate 4 and the sealing plate 5 are generally steel plates, or other materials that can play a waterproof role. The reserved plate 4 is embedded in the embedded groove 3 and cooperates with the sealing plate 5 to form a second waterproof measure. At the same time, with the function of the portable disassembly and assembly sealing mechanism, a sealing structure is formed inside the basement, which is the third waterproof measure. Through the multi-level waterproof setting, the possibility of infiltration is slowed down. At the same time, when infiltration occurs, it is also convenient to quickly repair leaks in the basement, avoiding the problem of inconvenient repair caused by integrated casting.

[0027] Furthermore, the portable disassembly and assembly sealing mechanism includes two sealing parts 9 that fit the shape of the inner wall of the mounting hole 2. The two sealing parts 9 are embedded on the inner wall of the mounting hole 2 facing each other. The two sealing parts 9 are embedded in the mounting hole 2 close to the inside of the basement, and the shape of the sealing parts 9 also has a certain gradient change, which prolongs the infiltration path of the infiltrated water and delays the infiltration. When leakage or material aging occurs, they can also be quickly replaced and repaired to avoid the problem of inconvenient repair due to integrated casting.

[0028] Furthermore, the two sealing parts 9 are both made of elastically deformable materials, and the two sealing parts 9 have an interference fit with the inner wall of the mounting hole 2 to improve its sealing performance. When the leak needs to be repaired, the sealing parts 9 are removed and replaced with suitable sealing parts 9.

[0029] Furthermore, a baffle plate 10 is fixedly connected to the inner side of one of the blocking pieces 9, and one of the blocking pieces 9 and the baffle plate 10 are connected by means of bolt fixing or bonding, and the baffle plate 10 is fixedly connected to the inner side of the other blocking piece 9. When the two blocking pieces 9 are spliced, the baffle plate 10 installed on one of the blocking pieces 9 overlaps the inner side of the other blocking piece 9. During installation, the baffle plate 10 can be bonded to the inner side of the other blocking piece 9 or fixedly connected by other means, and a certain sealing treatment is performed on the splicing gap between the two blocking pieces 9.

[0030] Furthermore, an annular sealing groove 8 is provided on the inner wall of the mounting hole 2 near the reserved plate 4, and a grouting groove 11 connected to the outer surface of the wall 1 is provided on the inner wall of the annular sealing groove 8. Sealing slurry can be poured into the annular sealing groove 8 and adjacent gaps through the grouting groove 11. The sealing slurry is polyurethane slurry or other sealing slurry, which fills the annular sealing groove 8 and adjacent gaps. After the polyurethane slurry hardens, a relatively stable sealing structure is formed.

[0031] Furthermore, a pipe sleeve 12 is fixedly connected to the inner wall of one of the sealing members 9, and a rotating screw 13 is threadedly connected to the inner wall of the pipe sleeve 12. One end of the rotating screw 13 is movably connected to the inner wall of the other sealing member 9 to ensure that the rotation of the rotating screw 13 is not affected. By rotating the rotating screw 13, the length of the rotating screw 13 entering the pipe sleeve 12 can be adjusted. When the two sealing members 9 are installed, the overall length of the pipe sleeve 12 and the rotating screw 13 is short, which does not affect the installation of the two sealing members 9. After the sealing members 9 are installed, the rotating screw 13 is rotated to make the rotating screw 13 slide toward the outside of the pipe sleeve 12. The overall length of the pipe sleeve 12 and the rotating screw 13 is lengthened, which squeezes the two sealing members 9 and makes the sealing members 9 fit more closely to the inner wall of the mounting hole 2.

[0032] Furthermore, a rotating handle 14 is fixedly connected to the outer surface of the rotating screw 13 to facilitate the rotation of the rotating screw 13 .

[0033] Furthermore, a guide groove 7 is provided at the bottom of the embedded groove 3 , and the guide groove 7 is connected to the outside of the wall 1 . When some infiltrated water enters the embedded groove 3 , the infiltrated water is gathered and guided to the outside of the wall 1 through the guide groove 7 .

[0034] The working principle of the waterproof sealing structure of the steel support penetrating the wall is explained in detail below.

[0035] like Figure 1-6 As shown, first, the reserved plate 4 is embedded in the embedded groove 3, and the sealing plate 5 is fixed on the reserved plate 4 to form one of the waterproof measures, and then the outer waterproof plate 6 is integrally cast in the installation hole 2 near the backfill side to form the outermost waterproof measure, and then the two plugging members 9 are embedded in the installation hole 2 near the inside of the basement, and the rotating screw 13 is rotated to make the rotating screw 13 slide to the outside of the pipe sleeve 12, and the overall length of the pipe sleeve 12 and the rotating screw 13 is lengthened, which squeezes the two plugging members 9, so that the plugging members 9 and the inner wall of the installation hole 2 fit more closely, and finally, the sealing slurry is poured into the annular sealing groove 8 and the adjacent gaps through the grouting groove 11. The sealing slurry is polyurethane slurry or other sealing slurry, and the annular sealing groove 8 and the adjacent gaps are filled. After the polyurethane slurry hardens, a relatively stable sealing structure is formed to improve the sealing performance.
