[0035] The embodiments of the present utility model will now be described in detail with reference to the accompanying drawings. These embodiments are only used to more clearly illustrate the technical solution of the present utility model, and are therefore merely examples and should not be construed as limiting the scope of protection of the present utility model. The specific structure of the present utility model is as follows: Figures 1-7 As shown in the image.
[0036] In modular concrete structures, the integrated thin-shell composite wall is formed by prefabricating, processing, and packaging the building facade materials in a factory, and then combining them with other prefabricated components to form a modular building.
[0037] Example 1: To solve one of the above-mentioned technical problems, the present invention adopts the following technical solution: an integrated thin-shell composite wall in a modular concrete structure, including a thin-shell structural plate 1, a precast beam 2, a precast wall 3, and matching embedded parts and reserved holes; the thin-shell structural plate 1 is installed along the front-back direction on the outer side of the vertically arranged precast wall 3; a precast beam 2 is provided at the top of the precast wall 3; the embedded parts include an anchor plate 6 and several embedded nuts 7, the middle part of the anchor plate 6 is embedded inside the precast beam 2 and both its left and right ends extend to the outside, and each of the embedded nuts 7 is embedded on both sides of the precast wall 3 and the precast beam 2 and is used to support the wall diagonal bracing respectively;
[0038] The precast beam 2 and the precast wall 3 are fixed by splicing them together vertically, and the thin-shell structural plate 1 and the precast wall 3 are fixed together by fixing them from front to back.
[0039] Based on any of the above technical solutions, a further optimization is made as follows: a number of lifting nails 8 are spaced apart on the top of the precast beam 2, the number of lifting nails 8 is not less than 2 and they are located in the middle area of the top of the precast wall 3; the lifting weight of the lifting nails 8 is not less than 4 tons, and they are used for component factory transfer and on-site hoisting operations.
[0040] It should be explained that placing the lifting nail 8 on top of the precast beam 2 and in the middle of the top of the precast wall 3 is to ensure that the position of the lifting nail 8 is precisely matched with the lifting center of gravity of the modular building unit, avoiding tilting of the components during the lifting process and ensuring the stability of transportation and lifting. The design of the lifting nail 8, which can lift a weight of not less than 4 tons, can meet the overall weight requirements of the precast components (including thin shell structural panel 1, precast beam 2, and precast wall 3), eliminating the need for disassembly and lifting, reducing the number of on-site lifting operations, making installation convenient and construction fast, while reducing the risk of component collisions caused by multiple lifting operations and ensuring construction quality.
[0041] Based on any of the above technical solutions, a further optimization is made by providing a number of threaded blind holes 11 at intervals at the bottom of the precast wall 3.
[0042] It should be explained that the pre-drilled threaded blind hole 11 at the bottom of the precast wall 3 is to enable the precast wall 3 to be quickly connected to the foundation or other precast units below. No additional drilling is required on site; the fixing can be completed directly by bolts engaging with the threaded blind hole 11. This avoids damage to the wall structure caused by on-site drilling and ensures the accuracy of the connection position. It also realizes the advantages of factory prefabrication, which allows for precise control of component quality and avoids construction errors, reduces on-site operation procedures, further shortens the construction period, and reduces labor costs.
[0043] Based on any of the above technical solutions, a further optimization is made as follows: wall-side through grooves 12 are respectively provided on the two side walls of the precast wall 3 along their height direction, and the top of each wall-side through groove 12 extends to the bottom of the precast beam 2.
[0044] It should be explained that the wall-side through-groove along the height of the precast wall 3 and extending to the bottom of the precast beam 2 serves the core function of providing a pre-set laying channel for building intelligent systems (such as security and lighting pipelines) and green building systems (such as fresh air and underfloor heating pipelines). This eliminates the need for later slotting in the wall or precast beam 2, protecting the structural integrity of the components and ensuring smooth and continuous pipeline layout, avoiding pipeline intersections and conflicts. It also meets the requirements for integration with intelligent and green building systems, enhancing design flexibility while reducing on-site pipeline construction workload, thus achieving the advantages of cost savings and improved construction efficiency.
[0045] Based on any of the above technical solutions, a further optimization is made: each reserved hole is set at a preset position on the precast wall 3 and the precast beam 2.
[0046] It should be explained that the pre-drilled holes in the precast wall 3 and precast beam 2 at the preset locations are planned in advance based on the functional requirements of the building (such as pipeline installation and equipment installation). During factory prefabrication, the dimensional accuracy and positional accuracy of the holes can be ensured through precision machining. There is no need for secondary drilling on site, which avoids quality problems such as component cracking and dimensional deviation caused by on-site drilling. At the same time, it can directly adapt to the installation requirements of various systems. Factory prefabrication can control quality, reduce construction errors, further improve construction efficiency, and ensure the overall performance of the building.
[0047] Based on any of the above technical solutions, a further optimization is made: both the precast wall 3 and the precast beam 2 are provided with reinforcement 9 structures inside; the reinforcement 9 in the precast wall 3 is arranged longitudinally in the vertical direction.
[0048] It should be explained that the reinforcement 9 structure inside the precast wall 3 and precast beam 2 is designed to meet the structural strength requirements of the components and ensure that the walls and beams can withstand the building's self-weight and external loads (such as wind and seismic forces). The reinforcement 9 inside the precast wall 3 is arranged longitudinally in the vertical direction, which matches the vertical stress characteristics of the wall and can effectively distribute the vertical load, preventing cracking of the wall due to uneven stress. This design avoids the arbitrariness of on-site reinforcement 9 by standardizing the reinforcement 9 in the factory (precisely controlling the spacing and specifications of the reinforcement 9), improving the overall quality and controllability of the building, and ensuring the safety and stability of the modular structure.
[0049] Example 2: Compared with Example 1, this example also includes the following technical features:
[0050] Based on any of the above technical solutions, a further optimization is to add a transverse reinforcing rib 10 along the left and right directions at the location of the embedded nut 7, and the transverse reinforcing rib 10 is connected to the longitudinal reinforcing rib 9.
[0051] It should be explained that the embedded nut 7 is used to connect the wall diagonal brace, which is a stress concentration point. The addition of transverse reinforcing bars 10 along the left and right directions and their connection with the longitudinal reinforcement bars 9 can form a local stress reinforcement structure, effectively dispersing the horizontal force transmitted by the diagonal brace and preventing damage to the concrete around the embedded nut 7 due to stress concentration. At the same time, the connection between the transverse reinforcing bars 10 and the longitudinal reinforcement bars 9 can make the reinforcement bar 9 structure form a whole, improving the shear and torsional resistance of the precast wall 3, improving the overall quality and quality control of the building, and ensuring the reliability of the wall support.
[0052] Based on any of the above technical solutions, a further optimization is made: the reinforcement 9 in the precast beam 2 is arranged longitudinally in the left and right directions, and additional dense reinforcement 5 is added in the up and down directions at the keyway 4 position at the beam end.
[0053] It should be explained that the precast beam 2 mainly bears the lateral load (such as the weight of the upper component and the horizontal force). The reinforcement 9 is arranged longitudinally in the left and right directions to accurately bear the lateral force and avoid the beam bending deformation. The keyway 4 at the beam end is the key part of the splicing of the precast beam 2 and the adjacent component. The load needs to be transferred during the splicing. The addition of dense reinforcement 5 in the up and down directions can enhance the structural strength of the keyway 4 and prevent the keyway 4 from cracking or breaking due to stress during the splicing process.
[0054] Based on any of the above technical solutions, the following optimization is made: all the reinforcement 9 are located inside the component and are not exposed, and the ends of the reinforcement 9 are connected to the embedded parts embedded in the precast wall 3 and the precast beam 2 to enhance the overall structural stability.
[0055] It should be explained that the reinforcement 9 is located inside the component and is not exposed, which can prevent the reinforcement 9 from being affected by the external environment (such as rain and humidity) and corroding, thus extending the service life of the component. At the same time, it ensures the flatness of the component's exterior surface, which facilitates the subsequent installation of the thin shell structural panel 1. The end of the reinforcement 9 is connected to the embedded part, which allows the reinforcement 9 and the embedded part to form an integral force system. This allows the load to be effectively transferred to the embedded part through the reinforcement 9, and then to the adjacent components through the embedded part, thereby improving the overall stress stability of the modular unit.
[0056] Based on any of the above technical solutions, a further optimization is made as follows: keyways 4 are respectively provided on the end faces of the two ends of the precast beam 2. The keyways 4 are grooves that are recessed into the interior of the precast beam 2, and the inner wall surface of the groove is a rough surface.
[0057] It should be explained that the inwardly recessed keyways 4 at both ends of the precast beam 2 are designed to precisely fit with the protrusions of adjacent precast beams 2 or building frames, enabling rapid positioning during splicing, reducing on-site adjustment time, and facilitating convenient installation and fast construction. The inner wall of the groove is designed to be rough, which increases the contact area and friction between the keyway 4 and the protrusion. If used with an adhesive, it can also improve the bonding strength, ensuring more effective load transfer after splicing and preventing loosening at the splicing points.
[0058] Based on any of the above technical solutions, the following further optimization is made: the thin-shell structural panel 1 is made of environmentally friendly materials and is fixedly attached to the outside of the prefabricated wall 3 with both ends flush with the prefabricated wall 3, covering the entire height of the prefabricated wall 3 in the vertical direction and having sound insulation, heat insulation and thermal insulation properties.
[0059] It should be explained that fitting the outer side of the precast wall 3 with both ends flush and covering the entire height ensures the integrity and aesthetics of the building facade, reduces splicing gaps, and prevents rainwater from seeping in through the gaps. Its sound insulation, heat insulation, and thermal insulation properties can directly improve the living comfort of the building and reduce the need for additional thermal insulation and sound insulation layers in the later stages. At the same time, factory prefabrication can ensure the dimensional accuracy of the thin-shell structure panel 1 and ensure its compatibility with the precast wall 3.
[0060] This utility model also includes the following advantages: 1. The prefabrication and on-site installation of the integrated thin-shell composite wall in the modular concrete structure of this utility model can reduce waste in terms of labor and materials, thus lowering construction costs. The fast construction speed can shorten the construction period, further reducing the cost of labor and materials.
[0061] 2. In modular concrete structures, the integrated thin-shell composite walls are prefabricated in the factory, allowing for precise control of component dimensions and quality, effectively avoiding errors and quality issues during construction. Furthermore, the integrated thin-shell composite walls in modular concrete structures utilize high-quality, environmentally friendly materials, providing better sound insulation, heat insulation, and thermal insulation performance, thus improving the overall quality of the building.
[0062] 3. The components of the integrated thin-shell composite wall in a modular concrete structure can be customized according to design requirements, enabling a wide variety of facade effects. Furthermore, the integrated thin-shell composite wall in a modular concrete structure can be integrated with other building systems to provide more diverse spatial layouts and functional requirements.
