[0027] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0028] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0029] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0031] Combine the following Figures 1 to 3 , describing an embodiment of the utility model.

[0032] According to an embodiment of the utility model, a wall bushing assembly is provided, comprising:

[0033] The first plate 2 is suitable for being fixedly connected to the side of the wall 1 facing the outdoors. The first plate 2 is provided with a first hole 21. Along the axis direction of the first hole 21, the projection of the first hole 21 does not overlap with the projection of the structural steel bars of the wall 1. The wall 1 is provided with a through hole corresponding to the first hole 21.

[0034] The casing 3 passes through the wall 1 via the through hole, and the interior of the casing 3 is suitable for accommodating equipment pipelines.

[0035] The wall sleeve assembly provided in the present embodiment makes it possible to avoid the position of the structural steel bars of the wall 1 when opening a through hole for accommodating equipment pipelines corresponding to the first hole 21, thereby avoiding damaging the structural steel bars of the wall 1 and causing damage to the original structure. In addition, opening a hole in the wall 1 corresponding to the first hole 21 can greatly reduce the size of the hole and reduce the adverse effects on the main structure.

[0036] Specifically, a steel bar scanner can be used to detect the position of the structural steel bars, or the method of stripping the steel bar protective layer can be used to find the position of the structural steel bars (it should be noted that the method of stripping the steel bar protective layer is well known to those skilled in the art), and mark them so that when the first plate 2 is fixed on the side of the wall 1 facing the outdoors, the projection of the first hole 21 along its axial direction avoids the structural steel bars.

[0037] As a preferred implementation form, the axis of the first hole 21 is parallel to the thickness direction of the wall 1. At the first hole 21, a water drill is used to drill a through hole in the wall 1 along the axis direction of the first hole 21. Since the projections of the first hole 21 and the structural steel bars of the wall 1 do not overlap along the axis direction of the first hole 21, the through hole does not pass through the location of the structural steel bars, thereby avoiding damage to the structural steel bars and causing damage to the original structure, thereby avoiding potential safety hazards. In the related art, the use of a hole opener or a rope saw to open a hole still has the problem of the hole being too large. The use of a water drill to open a through hole corresponding to the first hole 21 and to form a hole in one go can greatly reduce the size of the hole and reduce the adverse effects on the main structure compared to the use of a hole opener or a rope saw to open a hole.

[0038] A second plate 6 is fixedly connected to the first plate 2 on the side of the wall 1 facing the interior, and a second hole is opened in the second plate 6 corresponding to the first hole 21. The sleeve 3 passes through the first hole 21, the through hole and the second hole in sequence, and the two ends of the sleeve 3 passing through the wall 1 are fixedly connected to the first plate 2 and the second plate 6 respectively, so as to enhance the overall stability of the wall sleeve assembly.

[0039] In some embodiments, in combination Figures 1 to 3 As shown, there is a gap between the first plate 2 and the wall 1 to form a first cavity, and a second cavity is formed between the outer peripheral wall of the sleeve 3 and the inner wall of the through hole. The first cavity is connected to the second cavity, and the first cavity and the second cavity are suitable for accommodating the structural adhesive 4.

[0040] The wall-penetrating sleeve assembly provided in this embodiment fills the first cavity and the second cavity with structural adhesive 4 so as to form a fixed connection between the sleeve 3 and the wall 1, and between the first plate 2 and the wall 1, thereby improving the overall stability of the wall-penetrating structure.

[0041] Specifically, the spacing between the first plate 2 and the wall 1 is L, wherein 0mm<L≤10mm, and the gap between the first plate 2 and the wall 1 is suitable for forming a first cavity; the spacing between the second plate 6 and the wall 1 is S, wherein 0mm<S≤10mm, and the gap between the second plate 6 and the wall 1 is suitable for forming a third cavity; the gap between the outer peripheral wall of the sleeve 3 and the inner wall of the through hole is suitable for forming a second cavity, and the first cavity, the second cavity and the third cavity are connected and filled with structural adhesive 4, and the structural adhesive 4 adopts building structure Class A adhesive, such as perfusion steel adhesive, so as to be suitable for bonding and fixing the first plate 2, the second plate 6 and the sleeve 3 to the wall 1 through the structural adhesive 4.

[0042] Additionally, areas on both sides of the wall 1 corresponding to the first plate 2 and the second plate 6 are partially recessed to form grooves, so as to increase the contact area between the structural adhesive 4 and the wall 1 after the first cavity and the third cavity are filled with the structural adhesive 4, thereby enhancing the reliability of the adhesion.

[0043] In some embodiments, in combination Figures 1 to 3 As shown, a circle of sealing layer is arranged around the edge of the first plate 2, the sealing layer is suitable for sealing the opening of the first cavity, and a pouring gap connected to the first cavity is opened on the top of the sealing layer to be suitable for pouring structural adhesive 4 into the first cavity through the pouring gap.

[0044] The wall sleeve assembly provided in this embodiment provides a sealing layer at the edge of the first plate 2 to seal the opening of the first cavity, thereby preventing the structural adhesive 4 from leaking from the gap between the first plate 2 and the wall 1 when filling the first cavity with the structural adhesive 4.

[0045] Specifically, the enclosing layer is constructed of sealant, and a circle of enclosing layer is also provided at the edge of the second plate 6. The enclosing layer can also be constructed of a straight plate or a curved plate fixedly connected to the gap between the edge of the first plate 2 or the second plate 6 and the wall 1. A pouring gap connected to the first cavity or the second cavity is reserved at the top of the enclosing layer. Construction personnel are suitable for pouring structural glue 4 into the first cavity or the second cavity through the pouring gap. The enclosing layer is suitable for preventing the structural glue 4 from leaking in the gap between the first plate 2 or the second plate 6 and the wall 1 before the first cavity, the second cavity and the third cavity are filled with the structural glue 4.

[0046] In some embodiments, in combination Figures 1 to 3 As shown, the first plate 2 is provided with at least one first hole 21 , the number of the sleeves 3 matches the number of the first holes 21 , and each first hole 21 is provided with a sleeve 3 .

[0047] Preferably, when there are a plurality of first holes 21 , the plurality of first holes 21 are evenly and equidistantly distributed on the first plate 2 .

[0048] In some embodiments, in combination Figures 1 to 3 As shown, the sleeve 3 is sealed and connected to the first hole 21 .

[0049] The wall bushing assembly provided in this embodiment seals the junction between the bushing 3 and the first hole 21 to improve the waterproof effect of the junction between the bushing 3 and the first hole 21, thereby avoiding the hidden danger of water leakage at this location.

[0050] Additionally, the junction between the sleeve 3 and the second hole is also sealed.

[0051] In some embodiments, in combination Figures 1 to 3 As shown, the casing 3 comprises a steel pipe, the first plate 2 comprises a steel plate, and the steel pipe and the steel plate are fully welded together.

[0052] Specifically, the sleeve 3 includes a metal tube or a non-metal tube, and the first plate 2 and the second plate 6 include a metal plate or a non-metal plate. When the sleeve 3 is a metal tube and the first plate 2 and the second plate 6 are metal plates, a sealed connection form of full welding connection is adopted; when the sleeve 3 is a non-metal tube and the first plate 2 and the second plate 6 are non-metal plates, a sealed connection form of applying a sealant at the joint is adopted.

[0053] As a feasible implementation form, the sleeve 3 is a steel pipe, and the first plate 2 and the second plate 6 are both steel plates. The steel pipe is fully welded to the first hole 21 and the second hole, and the steel plate and the steel pipe are welded around each other to ensure the sealing and improve the waterproof ability to avoid water leakage. Before the first plate 2 and the second plate 6 are mounted on the wall, the surface of the wall 1 at the corresponding position is cleaned, the surface covering soil and floating slurry are removed, and the wall is polished to meet the requirements of steel bonding. The bonding surface of the steel plate needs to be polished with an angle grinder to reveal the metallic luster. The rougher the steel plate surface should be polished, the better. The grinding direction should be parallel to the force direction of the steel plate, and then the steel surface is wiped with acetone. After the steel plate is polished, it should be protected to prevent rusting again. Use a spatula to apply the structural adhesive to the surface of the wall 1 and the local area of ​​the steel plate pasting surface, and then paste the steel plate to the wall 1. After the steel plate and the wall 1 are firmly bonded, a circle of enclosure layer is set at the edge of the steel plate, and a pouring gap is opened on the top of the enclosure layer to facilitate pouring the structural adhesive 4 into the first cavity, the second cavity and the third cavity through the pouring gap. The structural adhesive 4 adopts pouring steel adhesive, which has high bonding strength, excellent waterproof performance, and dense pouring, so that the steel pipe, steel plate and structure are bonded as a whole, which improves the waterproof performance and structural strength, strengthens the structure, and improves the safety of the structure.

[0054] In some embodiments, in combination Figures 1 to 3 As shown, a waterproof layer 5 is provided on the side of the wall 1 facing the outdoors, and the waterproof layer 5 is suitable for sealing the junction between the first plate 2 and the wall 1 .

[0055] The wall sleeve assembly provided in this embodiment improves the waterproof effect at the junction between the first plate 2 and the wall 1 by making the waterproof layer 5 seal the junction there, thereby avoiding the hidden danger of water leakage at this location.

[0056] Specifically, the waterproof layer 5 is fixed to the side of the wall 1 facing the outdoors and covers the junction between the first plate 2 and the wall 1 to seal the gap between the first plate 2 and the wall 1, thereby preventing water leakage.

[0057] In some embodiments, in combination Figures 1 to 3 As shown, the waterproof layer 5 includes a sealant layer 51 , which is arranged around the edge of the first plate 2 to seal the interface between the edge of the first plate 2 and the wall 1 .

[0058] Specifically, a circle of sealant is applied along the edge of the first plate 2 to form a sealant layer 51, thereby sealing the gap at the junction of the first plate 2 and the wall 1, which is beneficial to improving the waterproof effect there.

[0059] In some embodiments, in combination Figures 1 to 3 As shown, the waterproof layer 5 also includes a waterproof roll 52 , which is applied to the first plate 2 and the wall 1 to seal the sealant layer 51 .

[0060] Specifically, the waterproof coiled material 52 extends from the first plate 2 to the wall 1 and covers the sealant layer 51 , so as to isolate the sealant layer 51 from external moisture, thereby enhancing the water-blocking effect of the sealant layer 51 .

[0061] In some embodiments, in combination Figures 1 to 3 As shown, the waterproof layer 5 also includes a waterproof mortar layer, which is located on the side of the waterproof roll material 52 away from the wall 1 and covers the waterproof roll material 52 to be suitable for sealing the waterproof roll material 52.

[0062] Specifically, the waterproof mortar layer covers the waterproof roll 52 and covers the junction between the waterproof roll 52 and the wall 1 and the first plate 2, thereby sealing and protecting the waterproof roll 52, and further improving the effect of preventing water leakage at the junction of the first plate 2 and the wall 1. By strengthening waterproofing on the outside of the wall 1 and the first plate 2, that is, by providing a sealant layer 51, a waterproof roll 52 and a waterproof mortar layer, adding multiple waterproof barriers is conducive to greatly reducing the hidden danger of water leakage.

[0063] Obviously, the above embodiments are only examples for clear explanation, and are not intended to limit the implementation methods. Although the embodiments of the present utility model are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present utility model, and such modifications and variations are all within the scope defined by the present utility model.
