Abstract
Description
Technical Field
[0001] This utility model relates to the field of building base concrete construction structure technology, and in particular to a self-healing concrete building facade structure. Background Technology
[0002] Self-healing concrete possesses self-healing capabilities. For example, Chinese Patent CN116199482B provides a crack-healing concrete composition, comprising the following raw material components by weight: 1000 parts coarse aggregate, 500-800 parts fine aggregate, 250-400 parts cement, 35-50 parts silica fume, 130-200 parts mineral powder, 3-10 parts water-reducing agent, and 80-200 parts microbial-loaded self-healing particles. The microbial-loaded self-healing particles, from the inside out, consist of: a core layer, a first coating layer, and a second coating layer. The core layer is a porous material loaded with Bacillus subtilis; the first coating layer is a first cross-linked sodium alginate; and the second coating layer is a second cross-linked sodium alginate containing nutrient solution and polycarboxylate water-reducing agent. This crack-healing concrete composition exhibits good self-healing performance and rapid self-healing speed when microcracks occur after the concrete has cured into cement. Self-healing concrete can be used for building base protection, such as on the vertical building surface of underground garages (or other similar construction scenarios), to play a protective role. However, in actual use, although it has good micro-crack repair performance, under the condition of the facade structure (plus the harsh environmental conditions that may exist in underground garages, such as dampness and vibration), self-healing concrete may fall off before the repair is completed. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model provides a self-healing concrete building facade structure, which solves the problem that self-healing concrete may detach before the repair is completed in existing technologies.
[0004] According to an embodiment of this utility model, a self-healing concrete building facade structure includes an erected building base and an adhesive concrete layer covering the building base, as well as a self-healing concrete layer covering the surface of the adhesive concrete layer. The adhesive concrete layer has a first channel penetrating both sides, and an inner support strip is laterally arranged within the self-healing concrete layer. The inner support strip is fixedly connected to a protrusion, and the protrusion is embedded in the adhesive concrete layer. The adhesive concrete layer between the self-healing concrete layer and the building base provides better strength to the entire structure. When cracks appear in the outer self-healing concrete layer, it will automatically repair itself. During this process, the inner support strip and the adhesive concrete layer maintain stability, preventing premature detachment before repair is complete. This solves the problem in existing technologies where self-healing concrete may detach before repair is complete.
[0005] Furthermore, the protrusions include a plurality of protrusions arranged along the length of the inner support bar.
[0006] Furthermore, the first channel is inclined and its higher end is away from the self-healing concrete layer.
[0007] Furthermore, it also includes a support plate that rests against the building base, with both the bonding concrete layer and the self-healing concrete layer located above the support plate.
[0008] Furthermore, the side of the support plate that abuts against the building base has a recessed notch.
[0009] Furthermore, a receiving groove is recessed on the surface of the pallet away from the bonding concrete layer.
[0010] Furthermore, a support plate is installed above the bonding concrete layer and the self-healing concrete layer.
[0011] Furthermore, the building base layer is covered from bottom to top with multiple sets of bonding concrete layers, self-healing concrete layers, and support plates, with a second channel forming a circle between the upper and lower adjacent support plates.
[0012] Furthermore, a pipe is inserted into the second channel.
[0013] Furthermore, the thickness of the self-healing concrete layer is less than the thickness of the bonded concrete layer.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] The stability of the overall structure is increased by setting an adhesive concrete layer. When cracks appear in the self-healing concrete layer on the outside, it will automatically repair itself. During the process, the inner support strips and adhesive concrete layer can maintain the stability and prevent the self-healing concrete from falling off before the repair is completed. This solves the problem in the prior art that the self-healing concrete may fall off before the repair is completed. Attached Figure Description

[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.
[0023] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0024] In an exemplary implementation, such as Figure 1-3As shown, this embodiment provides a self-healing concrete building facade structure, which includes an erected building base 1 and an adhesive concrete layer 2 covering the building base 1, and a self-healing concrete layer 3 covering the surface of the adhesive concrete layer 2. The adhesive concrete layer 2 is provided with a first channel 4 penetrating both sides of it. An inner support strip 5 is also provided laterally inside the self-healing concrete layer 3. The inner support strip 5 is completely covered inside the self-healing concrete layer 3 and is not exposed. The inner support strip 5 is fixedly connected with a protrusion 6, and the protrusion 6 is partially embedded in the adhesive concrete layer 2. The bonding concrete layer 2 reinforces the structure between the building base layer 1 and the self-healing concrete layer 3, making the overall structure more stable. Simultaneously, the internal support strips 5 provide support, preventing the self-healing concrete layer 3 from sagging even if cracks appear, thus ensuring it won't detach during the repair process. This solves the problem in existing technologies where self-healing concrete may detach before the repair is complete. In a further embodiment, the thickness of the self-healing concrete layer 3 is less than the thickness of the bonding concrete layer 2. The self-healing concrete layer 3 is located on the outer side, directly contacting the outside, while the bonding concrete layer 2 is located in the middle and therefore not in contact with the outside, making it less prone to cracking. In other words, the self-healing concrete layer 3 protects the inner bonding concrete layer 2. Even if cracks appear in the self-healing concrete layer 3, it can self-heal. Furthermore, the self-healing concrete layer 3 uses self-healing concrete (as described in the background section of the prior art (publication number CN116199)). The self-healing concrete provided by Chinese Patent 482B has a high raw material cost. Making the self-healing concrete layer 3 thinner can reduce the overall cost. In a more specific solution, there can be multiple internal support strips 5, which provide upward support to the self-healing concrete layer 3 in the longitudinal direction. The protrusions 6 can be multiple in the length direction, partially embedded in the bonding concrete layer 2, making them more stable and thus providing a more stable upward support. In a further solution, the building base layer 1 and the self-healing concrete layer 3 can be connected by a first channel 4. After the self-healing concrete layer 3 develops cracks, a small amount of water vapor may enter and infiltrate the internal structure, condensing into water inside. The first channel 4 can allow this water to be discharged outward, preventing a large amount of water from accumulating inside. More specifically, the first channel 4 can be inclined, with the higher end facing away from the self-healing concrete layer 3, which can better prevent water from entering and accumulating in the internal structure.
[0025] like Figure 1-4As shown, the facade structure also includes a support plate 7, which abuts against the building base 1. Both the bonding concrete layer 2 and the self-healing concrete layer 3 are located above the support plate 7. The support plate 7 can also be installed above the bonding concrete layer 2 and the self-healing concrete layer 3. This allows multiple sets of bonding concrete layers 2, self-healing concrete layers 3, and support plates 7 to be laid from bottom to top on the building base 1, forming multiple regional structures on the building base 1. This makes each region less prone to cracking and less likely to affect each other. Furthermore, a notch 8 is recessed on the side of the support plate 7 that abuts against the building base 1. The notch 8 can be filled with bonding concrete, thereby forming a whole between the bonding concrete layers 2 in the upper and lower regions; in a further embodiment, the support plate 7 has a recessed groove 9 on the plate surface opposite to the bonding concrete layer 2, and the groove 9 between the upper and lower adjacent support plates 7 forms a circular second channel 10. This second channel 10 can allow water from the internal structure to be discharged outward. More specifically, a pipe 11 can also be inserted in the second channel 10 (one end of the pipe 11 can be located in the middle of the bonding concrete layer 2, and the other end can be connected to the outer surface of the self-healing concrete layer 3) to better discharge the internal water.
[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
