Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to an air tightness and waterproof reinforcement structure of an external wall through-wall pipeline of an ultra-low energy consumption building without demolding. Background Art

[0002] On September 22, 2020, during the 75th United Nations General Assembly, my country set the goal of achieving carbon peak by 2030 and carbon neutrality by 2060. Carbon peak and carbon neutrality in the construction industry are crucial to the realization of the "dual carbon" goal. To achieve energy conservation and emission reduction in the construction industry, the development of ultra-low energy consumption buildings is one of the important means. Compared with the original energy-saving buildings, ultra-low energy consumption buildings have higher requirements in terms of thermal insulation performance and overall air tightness of the building. Door and window components and wall opening areas are the key considerations.

[0003] At present, the methods for air tightness, waterproofness and thermal insulation of through-wall pipe openings are too complicated and the construction efficiency is low. The structure is relatively complex and the completion quality is poor, making it difficult to truly meet the requirements of ultra-low energy consumption buildings. For example: the gap between the pipe insulation layer and the reserved hole in the civil engineering cannot be dense. The waterproof vapor permeable membrane and the waterproof vapor barrier membrane need to be completely wrapped during construction. The waterproof vapor permeable membrane and the waterproof vapor barrier membrane must be pre-cut and processed. In addition, during actual construction, there are problems such as loose wrapping and inadequate wrapping of local concave corners. The work efficiency is low and the construction quality is difficult to guarantee. The embedded sleeve does not consider the outward slope when reserving the outer wall. At the same time, the slope of the through-wall pipe cannot meet the design requirements when it is placed. This makes the construction measures of high inside and low outside often unable to be met on site. The above problems pose hidden dangers to the waterproof and airtightness construction quality of through-wall pipes in ultra-low energy consumption buildings.

[0004] Therefore, providing an economical, efficient and high-quality wall sleeve construction process is one of the problems facing the construction market. Summary of the invention

[0005] The purpose of the utility model is to provide an airtight and waterproof reinforcement structure for external wall through-the-wall pipes of ultra-low energy consumption buildings that do not require formwork removal based on the above-mentioned deficiencies in the prior art. The pipes are installed using wall through-the-wall sleeves and inverted cone-shaped silicone sleeves. The pipes are non-contact with the wall through-the-wall sleeves. The inverted cone-shaped silicone sleeves are used to block thermal bridges at the pipe site. The inverted cone-shaped silicone sleeves are compacted to enter the air layer and the waterproof coating acts together to make the airtightness, thermal insulation and waterproof properties between the pipe and the wall through-the-wall sleeves meet the technical requirements.

[0006] The purpose of this utility model is achieved by the following technical solutions:

[0007] An air tightness and waterproof reinforcement structure for wall-penetrating pipes on the exterior wall of an ultra-low energy consumption building that does not require formwork removal is used to arrange the pipes through the wall, and is characterized in that it includes a wall-penetrating sleeve and an inverted conical silicone sleeve, wherein the wall-penetrating sleeve is arranged to penetrate the wall, the pipe hole size of the wall-penetrating sleeve is matched with the outer diameter size of the pipe, the inverted conical silicone sleeves are respectively arranged at both ends of the wall-penetrating sleeve, the inverted conical silicone sleeves have inner holes, the pipe is penetrated in the wall-penetrating sleeves, and the two sides are limited by the inverted conical silicone sleeves to form an inner high and an outer low shape from the inside to the outside of the wall.

[0008] The inner hole side wall of the inverted cone-shaped silicone sleeve is a structure that is thick at the top and thin at the bottom, and the inverted cone-shaped silicone sleeves on both sides are reversed up and down.

[0009] The outer wall and the inner wall of the inner hole form a certain slope from the outside to the inside of the wall, with the outer side lower and the inner side higher.

[0010] A closed air layer is formed between the wall sleeve and the inverted cone-shaped silicone sleeve.

[0011] The wall sleeve is arranged to vertically penetrate the wall.

[0012] The outer side of the wall is provided with a formwork-free insulation layer.

[0013] Premixed anti-cracking mortar plastering layers are coated on both sides of the wall, and a waterproof structure is arranged on the inner side of the premixed anti-cracking mortar plastering layers.

[0014] The waterproof structure is a waterproof coating or a waterproof coiled material.

[0015] The advantages of the utility model are:

[0016] 1) The structural design is reasonable. The gap between the wall sleeve and the pipeline is not filled with traditional polyurethane foam materials, but with hydrophobic rock wool and other insulation materials, so as to achieve the insulation effect through the closed air layer;

[0017] 2) Install inverted cone-shaped silicone sleeves before and after the wall sleeve and in opposite directions to naturally form a 5% internal high and external low structural requirement for the pipeline, effectively avoiding the inadequate setting of the slope of the wall sleeve on site;

[0018] 3) Using the "red wine bottle cork" structure and the principle of internal and external pressure difference to achieve the filling between the inverted cone-shaped silicone sleeve and the wall sleeve and pipeline, together with the air layer to form insulation, heat preservation and high airtightness;

[0019] 4) Apply a layer of 1.0mm thick waterproof coating on the surface of the inverted conical silicone sleeve on both sides and the junction of the pipe to increase the waterproof performance at the root of the pipe;

[0020] 5) Meet the requirements of air tightness and waterproofness of ultra-low energy consumption and mold-free exterior wall penetration pipes; waterproof coating, inverted cone-shaped silicone sleeve, and air layer can enable the wall penetration pipe to adapt to the adverse effects of vibration, expansion and contraction of the wall penetration opening of the external protective wall;

[0021] 6) It can make the wall-penetrating pipes achieve high airtightness, no leakage, and no thermal bridge. At the same time, it has fewer construction processes, high construction efficiency, and reliable construction quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following is a further detailed description of the features of the present invention and other related features through embodiments in conjunction with the accompanying drawings to facilitate understanding by technicians in the same industry:

[0025] like Figure 1-2 As shown, marks 1-9 in the figure respectively represent: concrete wall 1, wall sleeve 2, pipe 3, inverted cone-shaped silicone sleeve 4, exterior wall formwork-free insulation layer 5, enclosed air layer 6, premixed anti-cracking mortar finishing layer 7, waterproof coating 8, and auxiliary installation iron sheet 9.

[0026] Example: Combination Figure 1 and Figure 2 As shown, the air tightness and waterproof reinforcement structure of the ultra-low energy consumption building formwork-free external wall through-wall pipeline in this embodiment is used to set the pipeline 3 through the wall on the concrete wall 1. The concrete wall 1 includes adjacent inner and outer insulation walls. In some examples, the concrete wall 1 can be a variety of masonry walls.

[0027] The structure in this embodiment includes:

[0028] The wall sleeve 2 penetrates the concrete wall 1 and the external wall formwork-free insulation layer 5, and the outer wall of the wall sleeve 2 is fixedly connected to the concrete wall 1. In some examples, the external wall formwork-free insulation layer 5 can be an inner insulation layer and other external insulation materials such as rock wool, EPS board, etc.

[0029] The pipeline 3 extends into the wall sleeve 2 and passes through the external wall mold-free insulation layer 5 to the outside. There is an inverted cone-shaped silicone sleeve 4 and a closed air layer 6 between the pipeline 3 and the wall sleeve 2. In some examples, the pipeline 3 can be a PVC pipe.

[0030] Inverted conical silicone sleeves 4, two inverted conical silicone sleeves 4 are respectively sleeved on both sides of the pipe 3. Each inverted conical silicone sleeve 4 has an inner hole for the pipe 3 to pass through, and the side wall of the inner hole is thick at the top and thin at the bottom, and the outer wall and the inner wall of the inner hole naturally form a 5% slope with the outer side lower and the inner side higher; the two inverted conical silicone sleeves 4 on both sides of the pipe 3 are reversed up and down, so that the pipe 3 naturally forms a structural state of high inside and low outside on both sides of the concrete wall 1.

[0031] The enclosed air layer 6 is sealed on both sides by the inverted cone-shaped silicone sleeve 4, forming a pressure difference between the inside and outside of the concrete wall 1 through-wall hole to isolate the fluidity of the internal and external gases, and at the same time, it can also form an air insulation layer better.

[0032] The premixed anti-crack mortar plastering layer 7 is arranged on both sides of the concrete wall 1 to ensure the anti-crack performance of the wall and further ensure the smoothness of the wall surface.

[0033] The waterproof coating 8 is applied to the contact surface between the pipe 3 and the external wall formwork-free insulation layer 5, and on the indoor side, the waterproof coating 8 is applied to the inner surface of the concrete wall 1 to play a waterproof role. In some examples, the waterproof coating 8 can be a waterproof roll.

[0034] In this embodiment, in order to facilitate the installation of the inverted conical silicone sleeve 4, an auxiliary installation iron sheet 9 is provided, and the auxiliary installation iron sheet 9 is pressed on the contact surface between the inverted conical silicone sleeve 4 and the wall sleeve 2, so that the outer surface of the inverted conical silicone sleeve 4 is expanded and the silicone is pressed into the wall sleeve 2 and forms a better sealing state. Then, the inverted conical silicone sleeve 4 on the other side is pressed into the wall sleeve 2 through the auxiliary installation iron sheet 9.

[0035] In actual construction, this embodiment has the following construction process:

[0036] 1) Install the wall sleeve 2, position the wall sleeve 2 through the steel bars of the concrete wall 1, and penetrate the external wall formwork-free insulation layer. After positioning, pour concrete from both sides of the wall sleeve 2 at the same time, and fix the wall sleeve 2 after pouring;

[0037] 2) Install the pipe 3, insert the pipe 3 into the inverted cone-shaped silicone sleeve 4 and extend it through the concrete 1 and the outside of the external wall formwork-free insulation layer 5, while ensuring that the internal channel of the inverted cone-shaped silicone sleeve 4 is high inside and low outside, and insert another inverted cone-shaped silicone sleeve 4 into the other side of the pipe 3 on the inner side of the concrete wall 1 in the reverse direction;

[0038] 3) Fix the inverted conical silicone sleeve 4 on both sides respectively, and press the inverted conical silicone sleeve 4 into the air layer 6 between the wall sleeve 2 and the pipe 3 through the auxiliary installation iron sheet 9 and the pressure tool. The silicone of the exposed hole part of the inverted conical silicone sleeve 4 needs to be pressed in as tightly as possible. When pressing in the inverted conical silicone sleeve 4 on the other side, pay attention to use the auxiliary installation iron sheet 9 to tighten the inverted conical silicone sleeve 4 on the other side to prevent the thrust generated by the internal enclosed air layer 6.

[0039] 4) Apply waterproof coating 8, generally 1.0 mm thick, which covers the connection between the pipe 3 and the concrete wall 1 and evenly covers the surface of the inverted cone-shaped silicone sleeve 4.

[0040] In some examples, during the process of pressing the inverted conical silicone sleeve 4 into the air layer 6 between the wall sleeve 2 and the pipe 3 in step 3), a handheld hot spray gun may be used for heating, local cutting may be performed, and the cut surface may be polished and smoothed with a grinding wheel.

[0041] The working principle of this utility model:

[0042] 1) Using the principle of red wine bottle cork, combined with the inherent high and low temperature resistance, weather resistance, easy processing, waterproofness, softness and resilience, good impact resistance and other characteristics of silicone, inverted cone-shaped silicone sleeves 4 (large outside and small inside) are inserted at both ends of the pipe 3 to achieve the effects of heat preservation, waterproof and vapor isolation, and anti-deformation.

[0043] 2) Silicone is easy to process and can realize a structure in which the pipe 3 is high inside and low outside in the inner hole of the inverted conical silicone sleeve 4.

[0044] 3) The air pressure difference between the enclosed air layer 6 and the outside of the pipeline 3 is used to form the effects of self-sealing, heat preservation, and waterproofing.

[0045] In the specific implementation of this embodiment: the outer diameter of the inverted cone-shaped silicone sleeve 4 is 20 mm larger than the diameter of the wall sleeve 2; the inner diameter of the inverted cone-shaped silicone sleeve 4 is 30 mm smaller than the diameter of the wall sleeve 2; the height of the inverted cone-shaped silicone sleeve 4 is 80 mm, similar to the appearance of a red wine bottle cork.

[0046] The waterproof coating 8 is turned up 10-20 mm at the intersection of the pipe 3 and extends 100 mm outside the surface of the inverted cone-shaped silicone sleeve 4 and the external wall mold-free insulation layer 5.

[0047] The hole diameter of the wall sleeve 2 is larger than the diameter of the pipe 3 by 100 mm.

[0048] The thickness of the external wall formwork-free insulation layer 5 is 10mm-15mm.

[0049] Although the above embodiments have described the concepts and embodiments of the purpose of the utility model in detail with reference to the accompanying drawings, ordinary technicians in this field can recognize that various improvements and modifications can still be made to the utility model without departing from the scope of the claims, so they are not described one by one here.
