Description

Technical Field

[0001] The present invention belongs to the technical field of wall waterproofing and thermal insulation construction, and particularly relates to a water stop, a waterproofing and thermal insulation assembly and a waterproofing and thermal insulation structure for a trough plate exterior wall, and a construction method for adding a waterproofing and thermal insulation structure to an existing trough plate exterior wall. Background Art

[0002] Corrugated panels are ribbed panels with a grooved cross-section. Due to their factory prefabrication, ease of construction, time savings, and aesthetically pleasing appearance, they are widely used in the exterior walls of modern industrial plants. However, most existing factory buildings are very old, and their corrugated exterior walls lack waterproofing and thermal insulation, or their performance fails to meet current industry standards. Furthermore, they have long suffered from environmental erosion and damage, making them difficult to meet user needs. In the context of urban renewal, if these factory buildings are to be reused, their exterior walls must be repaired and renovated, with new waterproofing and thermal insulation measures added to improve their performance.

[0003] The waterproof and thermal insulation construction methods for building exterior walls can generally be divided into two types: external insulation and internal insulation, according to the different classifications of the location of the insulation layer. The external insulation measure is to install the insulation layer and the waterproof layer together on the outside of the exterior wall. This method is usually suitable for exterior walls with smooth exterior surfaces. For exterior walls composed of trough-shaped panels with uneven exterior surfaces, the construction of the insulation layer is more difficult. The internal insulation measure is to install the insulation layer and the waterproof layer on the inside and outside of the exterior wall respectively. The methods for fixing the insulation layer in the internal insulation measures generally include bonding, nail anchoring, and keel fixing. The bonding method is suitable for situations where the area and thickness of the insulation layer are not large. For the insulation of factory exterior walls, in order to achieve the ideal insulation effect, the area and thickness of the insulation layer are generally large, so this method is not very applicable. When fixing the insulation layer using the nail anchoring method and the keel fixing method, it is usually necessary to insert screws, bolts and other components deep into the wall, which may cause secondary damage to the trough-shaped panel exterior wall. Therefore, these two methods are not good. Moreover, compared with conventional integrally cast walls, walls formed by splicing and combining trough panels have more joints, and the joints of the walls are weak spots in waterproofing. The existing waterproof and thermal insulation structure has poor effect, and the existing construction method cannot improve the waterproof and thermal insulation performance of the trough panel exterior wall without changing its original appearance.

[0068] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. The advantages and features of the present invention will become more apparent from the following description and claims. It should be noted that the drawings are greatly simplified and not to exact scale, and are intended solely to facilitate and clearly illustrate the embodiments of the present invention.

[0069] Example 1:

[0070] refer to Figures 1 to 18 This embodiment provides a waterproof and thermal insulation structure for an exterior wall of trough panels 13, comprising a waterproof and thermal insulation assembly and a plurality of trough panels 13. The waterproof and thermal insulation assembly comprises a water stop 2, thermal insulation panels 3, and fixings 4. Preferably, the waterproof and thermal insulation structure may further include: a waterproof coating 10 applied to the exterior side of the trough panels 13; a waterproof mortar 11 filling the joints between adjacent trough panels 13; and thermal insulation material 12 filling the spaces between the thermal insulation panels 3 of adjacent trough panels 13.

[0071] Several trough plates 13 can be stacked in layers, and windows 14 can be set between two adjacent layers of trough plates 13. Each layer of trough plates 13 can include multiple trough plates 13 placed in sequence at the same height, and a joint is formed between the ends of two adjacent trough plates 13. A groove 1 is opened on the outer peripheral surface of the trough plate 13.

[0072] The water stop 2 includes a structure that is compatible with the groove 1, such as a protrusion or a bump. The water stop 2 is embedded between two adjacent trough plates 13, and a joint with the water stop 2 as the bottom and the opening facing the outdoors is formed between the two adjacent trough plates 13. The joint can be filled with waterproof mortar 11, so that the waterproof performance of the outer wall of the trough plate 13 is enhanced by the water stop 2 without damaging the outer wall of the trough plate 13.

[0073] The insulation board 3 is located on the side of the trough board 13 facing the indoor room. As an example, the insulation board 3 can be made of XPS extruded polystyrene board. The insulation board 3 can be adhered to the trough board 13 through a first layer of adhesive material 7.

[0074] The fixing member 4 is located on the side of the insulation board facing the indoor space. The fixing member 4 is connected to the water stop 2 and is used to fix the insulation board 3. More specifically, each insulation board 3 is abutted against a portion of the adjacent fixing member 4, and the insulation board 3 is fixed by the squeezing action of the fixing member 4. The fixing member 4 is preferably fixedly connected to the water stop 2. Therefore, when installing the fixing member 4, it is not necessary to drill holes in the trough plate 13, thereby preventing damage to the trough plate 13.

[0075] The joints formed between adjacent trough plates 13 are separated by the cooperation between the water stop 2 and the groove 1, and the side of the joint close to the room is sealed, so that the above-mentioned joint forms an open cavity only connected to the outside, so that the waterproof mortar 11 can be further filled in the joint, and the insulation board 3 is reinforced by the fixing member 4. The insulation board 3 can be fixed without driving screws, bolts and other parts into the wall of the trough plate 13, and the wall of the trough plate 13 will not be damaged.

[0076] It should be noted that the above-mentioned waterproof and heat-insulating structure can be used for the renovation and upgrading of the existing trough plate 13 exterior wall, and can also be used for the waterproof and heat-insulating application of the newly built trough plate 13 exterior wall.

[0077] Therefore, the waterproof and heat-insulating structure can seal the gap between two adjacent trough plates 13 through the cooperation between the waterproof and heat-insulating component and the groove 1, and fill the waterproof mortar 11 in the joint, thereby improving the waterproof effect. Combined with the waterproof coating 10 coated on the surface of the trough plate 13, the waterproof performance of the outer wall of the trough plate 13 is further enhanced. In addition, the insulation board 3 is pasted with the first adhesive material 7, and the insulation board 3 is fixed in combination with the fixing part 4 in the waterproof and heat-insulating component, without damaging the outer wall of the trough plate 13 itself, and the insulation board 3 can be fixed. The insulation board 3 is combined with the insulation material 12 filled in the gap to improve the insulation effect of the wall.

[0078] As a preferred embodiment, the grooves 1 have a square cross-section and extend along the length or width of the trough plate 13 within their respective outer circumferences. Two grooves 1 on any adjacent outer circumferences of each trough plate 13 are connected, allowing the waterstop 2 to completely conform to the outer circumference of the trough plate 13, ensuring that a waterstop 2 can be positioned between each gap between two adjacent trough plates 13 to achieve waterproofing. The waterproof coating 10 applied to the outdoor side of the trough plates 13 and the waterproof mortar 11 filling the joints between adjacent trough plates 13 further enhance the waterproofing of the trough plate 13 exterior walls.

[0079] As a preferred embodiment, the waterstop 2 includes a web 201 and two flanges 202. The web 201 is in the shape of an elongated strip and is sandwiched between two adjacent trough plates 13 to form a joint. The two flanges 202 are located on either side of the web 201 and fit into the groove 1 on the trough plate 13. The two flanges 202 preferably extend along the length of the web 201 and are perpendicular to the web 201. As a preferred embodiment, the cross-section of the waterstop 2 is in the shape of a cross, with the two flanges 202 symmetrically located on either side of the web 201. The side of the web 201 without the flange 202 is flush with the indoor side of the trough plate 13 to facilitate subsequent welding of the fixing member 4. The thickness of the web 201 is equal to the width of the joint between the trough plates 13. The waterstop 2 of the above structure can be standardized, which facilitates construction. When the specifications of the trough plates 13 and the groove 1 are unified, the construction difficulty can be effectively reduced.

[0080] As a preferred embodiment, when two water stop members 2 are connected, the ends of adjacent flanges 202 are provided with a 45-degree cut surface so that the ends of the flanges 202 of the two adjacent water stop members 2 fit together, preventing rainwater from penetrating through the end gaps of the two adjacent water stop members 2, thereby improving the sealing and waterproof performance.

[0081] As a preferred embodiment, the fixing member 4 includes a connected connecting plate 401 and an anchor plate 402. The connecting plate 401 is used to fix the fixing member 4 to the water stop member 2. The connecting plate 401 and the water stop member 2 are preferably welded together. The anchor plate 402 is used to fix the insulation board 3. As a preferred method, the connecting plate 401 and the anchor plate 402 are vertically connected to each other and are in a "T" shape. The insulation board 3 is clamped and fixed between the anchor plate 402 and the groove plate 13. The cross-sectional shapes of the connecting plate 401 and the anchor plate 402 are preferably rectangular, which can increase the contact area between the fixing member 4 and the insulation board 3 and achieve a better fixing effect.

[0082] As a preferred embodiment, the waterproof insulation component also includes a number of anchors 5. A number of holes 403 are provided on the anchor plate 402. Each hole 403 is distributed on both sides of the connecting plate 401 and passes through along the thickness direction of the anchor plate 402. The anchor 5 is in the shape of a rod. One end of the anchor 5 passes through the hole 403 on the anchor plate 402 and penetrates into the insulation board 3. The other end of the anchor 5 is located in the hole 403, and the end of the anchor 5 located in the hole 403 is fixed in the hole 403 by the anchoring glue 6 that fills the hole 403. One end of the anchor 5 is inserted into the insulation board 3 to fix the insulation board 3, and the other end is located in the hole 403, so that the surface of the side of the anchor plate 402 located inside the wall remains flat without any bulges, making the wall more tidy and beautiful.

[0083] As a preferred embodiment, the insulation board 3 is adhered to the side of the trough plate 13 facing the room through a first adhesive material 7, and the other side of the insulation board 3 is in contact with the anchor plate 402. The other side of the insulation board 3 opposite to the trough plate 13 is adhered with a finishing material 9 through a second adhesive material 8. The second adhesive material 8 should cover the fixing part 4. The insulation board 3 is adhered and fixed by the first adhesive material 7 and then reinforced by the fixing part 4. The insulation effect can be achieved without damaging the trough plate 13. The second adhesive material 8 and the finishing material 9 can improve the aesthetic effect of the wall.

[0084] Example 2:

[0085] refer to Figures 1 to 18 This embodiment provides a construction method for adding a waterproof and thermal insulation structure to the exterior wall of an existing trough plate 13, using the above-mentioned waterproof and thermal insulation structure. The construction method specifically includes the following steps: steps S1-S4, and further includes steps S5-S6.

[0086] S1. Dismantle the existing trough-shaped plate 13 and windows 14 of the exterior wall.

[0087] As a preferred embodiment, before performing step S1, the method further includes:

[0088] Inspect and clean the existing channel plate 13 exterior wall;

[0089] All the trough panels 13 and windows 14 of the existing trough panel 13 exterior wall are numbered and accurately positioned.

[0090] Check whether the trough plate 13 is damaged so that it can be repaired or replaced in time. During subsequent hoisting, the trough plate 13 can be installed according to the number so that the trough plate 13 can be returned to its original position.

[0091] In step S1 , the trough plate 13 may be removed only after all windows 14 are removed. The removal process should avoid damaging adjacent components.

[0092] As a preferred method, step S1 also includes: repairing each trough plate 13, each window 14, the partially undemolished wall 15 of the existing trough plate 13 exterior wall, and each frame column 16 supporting the existing trough plate 13 exterior wall. The repair work can improve the aging and damaged parts of the above-mentioned components to increase strength, extend service life, and improve aesthetic effects.

[0093] S2. A groove 1 is provided on the outer peripheral surface of the joint formed by each trough plate 13 and the adjacent trough plates 13, each trough plate 13 is fixed back to its original position and a water stop 2 is embedded in the joint between each trough plate 13.

[0094] As a specific implementation method, in step S2, each trough plate 13 is fixed back to its original position in turn by hoisting. After each trough plate 13 is hoisted and fixed, one side flange 202 of several water stop members 2 is promptly embedded in the corresponding groove 1 of the trough plate 13. When hoisting the adjacent trough plate 13, ensure that the other side flange 202 of the water stop member 2 on the trough plate 13 is inserted into the corresponding groove 1 of the adjacent trough plate 13.

[0095] As a preferred embodiment, the structure and position of the grooves 1 on each trough plate 13 are consistent, thereby reducing the difficulty of construction.

[0096] S3. Fill the joints between the trough-shaped plates 13 with waterproof mortar 11, and preferably also cover the surfaces of the trough-shaped plates 13 and the partially undemolished wall 15 facing the outdoor side with waterproof coating 10.

[0097] During actual construction, the color style of the waterproof coating 10 in the joint can be consistent with the original appearance of the existing trough plate 13 exterior wall, making the exterior wall color unified and more beautiful. The waterproof mortar 11 should be full and dense and flush with the outer surface of the trough plate 13.

[0098] S4. Fix the fixing member 4 to the surface of the water stop member 2 exposed to the indoor side, and fix the insulation board 3 to the side of the trough plate 13 facing the indoor side through the fixing member 4.

[0099] Specifically, a connecting plate 401 for connecting the fixing members 4 is fixed by welding to the surface of the waterstop 2 exposed indoors. As a preferred embodiment, when welding the fixing members 4 to the surface of the waterstop 2 exposed indoors, several fixing members 4 are welded to the web 201 of the waterstop 2 at equal intervals along the length of the waterstop 2 via the connecting plate 401. The number of fixing members 4 is set according to actual construction requirements.

[0100] As a preferred embodiment, the method for fixing the insulation board 3 in step S4 specifically includes: applying a first layer of adhesive material 7 on the indoor side of each trough-shaped board 13 and the partially undemolished wall 15 and bonding the insulation board 3, driving an anchor 5 into each insulation board 3 and fixing the anchor 5 with an anchor glue 6.

[0101] S5. Fill the gap between the insulation plates 3 of two adjacent trough-shaped plates 13 with insulation material 12.

[0102] During actual construction, the insulation material 12 should fill the gaps and be flush with the surface of the insulation board 3. By providing the insulation material 12, the insulation effect is further improved. The insulation material 12 can be a known liquid solidifiable material or a solid insulation material.

[0103] S6. Apply a second layer of adhesive material 8 on the surface of the insulation board 3 and adhere a finishing material 9. The second layer of adhesive material 8 is, for example, an adhesive.

[0104] The waterproof coating 10 on the outdoor side of the existing trough plate 13 exterior wall and the finishing material 9 on the indoor side are both sealed at the window 14 according to conventional technical requirements to ensure that the window 14 and the trough plate 13 are tightly connected and there is no gap. The waterproof and thermal insulation structure of the partial undemolished wall 15 of the existing trough plate 13 exterior wall is implemented according to conventional technical requirements and completed together with the waterproof and thermal insulation structure of the exterior wall trough plate 13 area. The trough plates 13 and windows 14 that are severely damaged and difficult to repair should be updated and replaced in the original style.

[0105] In terms of improving waterproof performance, the construction method of this embodiment embeds water-stopping parts 2 in each joint of the outer wall of the trough plate 13, fills waterproof mortar 11, and covers the outer surface of the trough plate 13 with waterproof coating 10. While restoring the original appearance of the existing outer wall of the trough plate 13, it significantly improves the weak waterproof part of the joint between the trough plates 13, thereby effectively improving the waterproof performance of the existing outer wall of the trough plate 13.

[0106] To improve thermal insulation performance, this embodiment secures the insulation board 3 to the interior of the existing trough panel 13 by providing a fixing member 4 on the waterstop 2 and combining adhesive material, anchors 5, and anchoring glue 6. Compared to exterior wall insulation fixing methods such as bonding, nailing, and stud fixing, this embodiment not only effectively secures the insulation board 3, which has a larger bonding area and thickness, but also eliminates the need to drive screws or other components deep into the wall. This improves the thermal insulation performance of the existing trough panel 13 exterior wall while avoiding secondary damage to the trough panel 13.

[0107] The above description is only a description of the preferred embodiments of the present invention and does not limit the scope of the present invention. Any changes and modifications made by ordinary technicians in the field of the present invention based on the above disclosure shall fall within the scope of protection of the claims.
