Description

Technical Field

[0001] This utility model relates to the field of wall renovation, and in particular to a structure and interior partition wall for wall renovation. Background Technology

[0002] When renovating and reinforcing the brick walls of old brick houses, the traditional approach, to preserve the original structural features as much as possible, is to first reinforce the walls with reinforced concrete, and then apply plaster to create the decorative surface. After reinforcement, the wall's structural layers, from the inside out, are: the original brick structure, the newly poured reinforced concrete layer, the plaster layer, the putty layer, and the paint layer. The newly poured reinforced concrete layer plays a crucial role in reinforcing the original brick structure, and its construction involves multiple steps, including tying reinforcing bars, erecting formwork, and pouring concrete.

[0003] However, the aforementioned traditional reinforcement methods have significant drawbacks. The processes of formwork erection, plastering, and puttying are quite complex and time-consuming, making it difficult to meet the requirements of projects with short construction cycles. Therefore, it is necessary to develop a new wall structure and reinforcement method to effectively reduce the construction cycle of renovation and reinforcement. Utility Model Content

[0004] The purpose of this utility model is to overcome the problem of long construction period when renovating and reinforcing the walls of old brick houses in the prior art, and to provide a structure and internal partition wall for renovating walls.

[0005] In a first aspect, the present invention provides a structure for modifying a wall, comprising: A shotcrete layer is provided, which is connected to the surface layer of the existing wall; a steel mesh is arranged inside the shotcrete layer. A keel layer, wherein the keel layer is connected to the surface layer of the shotcrete layer; The rock slab is fixedly connected to the keel layer; The decorative panel is connected to the side of the rock panel facing away from the keel layer.

[0006] This utility model provides a structure for renovating walls, in which the shotcrete layer and the internal steel mesh together form a reinforcement layer. This reinforcement layer adheres tightly to the surface of the existing wall, and through the synergistic effect of the steel bars and concrete, significantly enhances the load-bearing capacity of the existing wall, effectively improving its structural safety and stability. The keel layer functions to fix the PVC panels onto the shotcrete layer, providing a reliable support structure for the subsequent installation of the decorative panels. The decorative panels are fixed to the surface of the PVC panels, serving a decorative function to beautify the wall. Various materials and styles of decorative panels can be selected according to different design requirements to meet diverse decorative styles.

[0007] The shotcrete layer is applied using a shotcrete process, where concrete is directly sprayed onto the surface of the existing wall. Compared to traditional concrete pouring methods that require formwork, this process eliminates the need for formwork, simplifying the construction process, reducing the workload of formwork installation and removal, thereby effectively saving construction time and improving construction efficiency.

[0008] In the construction of the decorative surface layer, this solution uses the keel layer and the PVC board to fix the decorative panel, adopting a prefabricated dry construction method. Compared with the traditional wet construction method of plastering, puttying, and painting layers, dry construction eliminates the need to wait for the plaster and putty to dry before proceeding to the next step, avoiding construction delays caused by drying time and further shortening the construction cycle. At the same time, the prefabricated construction method helps ensure the consistency and stability of construction quality, improving the overall construction effect.

[0009] In summary, the structure for wall renovation provided by this utility model can effectively shorten the construction cycle and improve construction efficiency in the renovation and reinforcement of old brick house walls, while ensuring that the renovated wall has sufficient load-bearing capacity and good decorative effect.

[0010] The aforementioned Meiyan board, also known as Meiyan cement board, is a type of decorative fiber cement board. It is primarily made from cement, plant fibers, and adhesives, and is processed through steps such as pulping, molding, cutting, pressing, high-temperature steam curing, single-sheet drying, and sanding.

[0011] The arrangement of the keel layer is flexible; it can be a single-layer structure, i.e., only one main keel is set; or it can be a double-layer structure, consisting of a main keel and a secondary keel.

[0012] Preferably, the keel layer includes a main keel and a secondary keel. The main keel is vertically fixed to the surface layer of the shotcrete layer, and the secondary keel is horizontally fixed to the main keel. The PVC panel is fixedly connected to the secondary keel. In this design, the main keel is responsible for fixing the secondary keel, while the secondary keel is responsible for fixing the PVC panel. From the perspective of effect analysis, compared with the case of only setting one layer of main keel, this design, through the cooperation of the main keel and the secondary keel, allows for more precise leveling during installation. Because the double-layer structure allows for adjustment of the installation position of the PVC panel from different directions, it effectively improves the flatness of the PVC panel after installation, resulting in a more aesthetically pleasing and neat wall surface.

[0013] The main keel can be fixed to the sprayed concrete layer by pre-embedded bolts, structural adhesive, or expansion bolts.

[0014] Preferably, the main keel is equipped with a support clip, which is fixed to the shotcrete layer by expansion bolts. In this design, the support clip serves a dual purpose: firstly, it tightly secures the main keel to the expansion bolts; secondly, it levels the main keel, ensuring its flatness during installation. Compared to using structural adhesive, fixing with expansion bolts offers superior stability. Compared to pre-embedded bolts, expansion bolts do not require prior pre-embedding. In actual construction, pre-embedded bolts require precise positioning, and any deviation in the pre-embedded position makes subsequent adjustments difficult. Expansion bolts, however, can be flexibly positioned according to site conditions; installation is completed simply by drilling holes in the shotcrete layer at suitable locations, greatly improving construction flexibility and convenience.

[0015] Preferably, the system further includes a baseboard located between the decorative panel and the floor, the baseboard being connected to the PVC panel via a wooden base plate. In this design, the wooden base plate allows adjustment of the thickness gap between the baseboard and the PVC panel, ensuring the spacing meets design requirements. Simultaneously, the wooden base plate also serves to secure the baseboard, ensuring its stable installation.

[0016] Preferably, the decorative panel is replaced with gypsum board, and wallpaper is pasted on the surface of the gypsum board.

[0017] Preferably, the thickness of the sprayed concrete layer is 40mm-80mm.

[0018] Preferably, the thickness of the rock slab is 12mm-16mm.

[0019] In a second aspect, the present invention provides an internal partition wall, comprising an existing wall and a structure for modifying the wall as described in the first aspect, wherein the structure for modifying the wall is provided on both sides of the existing wall.

[0020] This utility model applies the structure used for wall modification to both sides of the existing wall, which can effectively shorten the construction cycle and improve construction efficiency in the renovation and reinforcement of the interior partition wall, while ensuring that the modified wall has sufficient load-bearing capacity and good decorative effect.

[0021] Preferably, the existing wall has through holes along its thickness direction, and through reinforcing bars are provided in the through holes. The two ends of the through reinforcing bars are respectively connected to the shotcrete layers on both sides of the existing wall.

[0022] In this design, the main function of the through-wall holes is to provide a passage for the through-wall reinforcing bars. The through-wall reinforcing bars enhance the connection between the shotcrete layers on both sides of the existing wall, ensuring a tight bond between the shotcrete layers and the existing wall, thereby significantly improving the overall structural connection performance and stability.

[0023] The through-wall reinforcement comes in two forms: straight and with hooks at both ends. If the through-wall reinforcement is straight, it needs to be tied to the reinforcing mesh in the shotcrete layer using binding wire to secure it. When the through-wall reinforcement has hooks at both ends, the hooks directly hook onto the reinforcing mesh in the shotcrete layer to achieve the connection.

[0024] Preferably, both ends of the through-wall reinforcement bar have hooks. In this design, the hooks are used to hook onto the reinforcing mesh in the shotcrete layer. Compared with straight through-wall reinforcement bars, the design with hooks at both ends significantly enhances the connection effect, making the connection more stable and effectively reducing the risk of detachment.

[0025] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model provides a structure for renovating walls, which can effectively shorten the construction cycle and improve construction efficiency in the renovation and reinforcement of old brick house walls, while ensuring that the renovated walls have sufficient load-bearing capacity and good decorative effect. This utility model provides an internal partition wall. By applying the structure used for wall modification to both sides of an existing wall, the internal partition wall can effectively shorten the construction cycle and improve construction efficiency in the renovation and reinforcement project, while ensuring that the modified wall has sufficient load-bearing capacity and good decorative effect.
