Description

Technical Field

[0001] The invention relates to a pipeline wall penetration device, in particular to a pipeline wall penetration device for integrating a thermal insulation structure and a manufacturing and construction process thereof. Background Art

[0002] At present, it is very important to promote the integrated technology of ultra-low energy consumption building insulation structure. However, traditional construction technology and equipment are difficult to meet the high air tightness, no thermal bridge, good insulation and energy saving characteristics of the integrated ultra-low energy consumption building insulation structure.

[0003] In the process of opening the traditional external wall opening, the main structure of the external wall concrete needs to be provided with a casing (or a reserved hole) and the pipeline is passed through the through hole. The pipeline and the casing (or reserved hole) are filled with insulation materials. Then, a waterproof vapor barrier membrane / waterproof vapor permeable membrane is pasted on the inside and outside of the main structure of the external wall to seal the gap between the pipeline and the through hole. Subsequently, an insulation layer is pasted on the outside of the external wall. The insulation at the pipeline position should be cut to avoid it. Finally, the plastering finish on the outside of the insulation is carried out. Based on the traditional through-wall pipe construction method and device, it can be found that the through-wall pipe and the casing are two separate devices, and there is an incoherent construction process. To ensure airtightness, the indoor and outdoor sides of the main structure still need a waterproof vapor barrier membrane / waterproof vapor permeable membrane to seal the pipeline circumference.

[0004] The integrated structure of the thermal insulation structure is generally composed of three parts: the reinforced concrete main structure, the thermal insulation layer, and the concrete protective layer. This system requires the simultaneous construction of the reinforced concrete main structure on the indoor side, the thermal insulation layer in the middle, and the outermost concrete protective layer. If the traditional casing device and construction technology are used, the pipeline openings of the thermal insulation layer and the protective layer will need to be excavated twice after the exterior wall construction is completed, which will destroy the waterproof tightness between the pipeline and the protective layer, and easily lead to cracking and water seepage problems. The thermal insulation between the casing and the pipeline can only be filled on one side, and the density cannot be guaranteed. The waterproof and breathable membrane on the outer surface of the reinforced concrete main structure on the outdoor side cannot be pasted, and airtightness measures cannot be achieved. It can be seen that the application of traditional casing devices and construction technology in the integrated system of building thermal insulation structure will lead to problems such as difficulty in engineering construction, failure to achieve design indicators, and failure to guarantee construction effects.

[0043] The pipeline wall penetration device for thermal insulation structure integration is suitable for thermal insulation structure integrated external wall construction. The casing 2 forms an integrated structure through the first ring rib 4 and the main pipeline, which can ensure the airtightness of the device itself, and only needs to be installed once during construction, reducing the construction process steps.

[0044] The casing 2 is used to be installed in a reinforced concrete wall 17. The filling space 7 between the casing 2 and the main pipeline 1 is filled with a heat-insulating material 12 to insulate the front end of the main pipeline and ensure the heat insulation of the pipeline wall penetration device.

[0045] The rear end of the sleeve 2 is sealed by a movable buckle cover 3, which is convenient for filling the thermal insulation material 12 and forming the thermal insulation structure. The structure of the first ring rib 4, the third ring rib 8, the movable buckle cover 3 and the end ring rib 9 is conducive to fixing the pipeline wall penetration device on the external wall structure, and the annular groove 13 above can be in close contact with the concrete to form a tight sealing surface, reducing the use of waterproof vapor barrier membrane or waterproof breathable membrane.

There is at least one inner ring rib 6, which can support the casing 2 to prevent deformation and displacement of the casing 2. At the same time, the filling space 7 is divided into at least two cavities by the inner ring ribs 6. The cavity near the front end is used to fill ordinary thermal insulation material 12, while the cavity near the rear end is used to fill thermal insulation material 12 with a high combustion grade, so as to achieve the fireproof performance of the pipeline wall penetration device.

[0055] When filling the insulation material 12, a tool is first used to inject the foam insulation material 12 into the front cavity through the ring rib through hole 16, and then the insulation material 12 with a combustion grade of Class A is filled into the rear cavity.

[0058] The manufacturing process of the pipeline wall penetration device of the present invention is used to manufacture the above-mentioned pipeline wall penetration device for integrated insulation structure. Through a special manufacturing and assembly process, an integrated pipeline wall penetration device is formed, which is convenient for the construction of the integrated insulation exterior wall structure.

[0059] The construction process of the pipeline wall penetration device for integrating thermal insulation structure of the present invention comprises the following steps.

[0060] a. Tie the steel bars to the reinforced concrete wall 17 of the exterior wall, and fix the pipeline wall penetration device for the integrated insulation structure to the steel bars of the main structure.

[0061] b. An insulation layer 18 and connecting components are fixedly installed on the outer side of the steel bar, and the rear part of the main line 1 of the pipeline wall penetration device with integrated insulation structure passes through the insulation layer 18, the inner side surface of the insulation layer 18 is in contact with the outer end surface of the movable buckle cover 3, and the thickness of the insulation layer 18 is less than the distance between the movable buckle cover 3 and the rear end of the main line 1.

[0062] c. Formwork is set up on both sides of the exterior wall, and the formwork on both sides is respectively in contact with the two ends of the main pipeline 1, and a gap is formed between the outer formwork and the exterior wall insulation layer 18.

[0065] f. The removable sealing cover 10 at the rear end remains in its original state, and when the outdoor pipeline is installed, the removable sealing cover 10 at the rear end is removed.

[0066] The integrated exterior wall of the insulation structure requires that the reinforced concrete wall 17 and the outer self-compacting concrete layer 19 be cast at the same time. It is impossible to reserve space for the wall-penetrating pipe, and it can only be installed by drilling holes later. This damages the exterior wall structure. At the same time, it is difficult to ensure the airtightness between the sleeve 2 and the wall. The contact surface between the reinforced concrete wall 17 and the insulation layer 18 is located inside the wall, making it difficult to construct a waterproof membrane.

[0067] The construction process of the present invention adopts a pipeline wall penetration device for thermal insulation structure integration. The device is a pre-processed integrated structure that is adapted to the size of the thermal insulation integrated exterior wall. During construction, the pipeline wall penetration device can be directly fixedly installed on the steel bars of the reinforced concrete wall 17 according to the designed threading position, and then the thermal insulation layer 18 is installed at the designed position. The main pipeline 1 passes through the thermal insulation layer 18, and concrete can be poured after the template is supported to form the inner reinforced concrete wall 17 and the outer self-compacting concrete layer 19, and the thermal insulation layer 18 is wrapped in the exterior wall structure to form the exterior wall structure in one piece. At the same time, the concrete poured in the reinforced concrete wall 17 is also in close contact with the outside of the casing 2 to form a sealing surface. The insulation between the casing 2 and the main line is completed during the production process of the pipeline wall penetration device, and no separate construction is required at a later stage. The pipeline wall penetration device also does not require subsequent hole opening and installation. In addition, since there is no need to construct a waterproof breathable membrane and a waterproof vapor barrier membrane, the construction steps and construction difficulty are reduced. There is no need to destroy the wall, thereby avoiding the impact of secondary excavation on the airtightness of the exterior wall structure.

[0068] The present invention has good air tightness, no thermal bridge, convenient construction, low cost, and no need for on-site secondary treatment. It can effectively solve the problems of protective layer leakage, unqualified air tightness, great difficulty in secondary construction, high construction cost, etc. caused by the need to open holes in traditional embedded pipes in the construction of ultra-low energy consumption building insulation integrated structure, and has obvious economic and social benefits.
