Abstract
Description
Technical Field
[0001] The invention relates to the technical field of building engineering, and in particular to a bolt-connected assembled high-strength lightweight frame wall structure system. Background Art
[0002] Prefabricated buildings refer to buildings that transfer a large number of on-site operations in traditional construction methods to factories, where building components are processed and manufactured in factories and transported to construction sites, where they are assembled and installed on site through reliable connection methods. Currently, the commonly used concrete prefabricated building technology systems mainly include the following types:
[0003] One is the prefabricated concrete shear wall (fully assembled) structural system, in which the vertical load-bearing shear wall is prefabricated, and the horizontal structural components are in the form of composite beams and composite floor slabs. The other is a cast-in-place concrete frame or cast-in-place concrete shear wall, combined with an external prefabricated concrete wall panel system; the cast-in-place concrete frame is a vertical load-bearing frame column that is cast in-place, and the horizontal structural components are in the form of composite beams and composite floor slabs. The other is a modular integrated building (MiC building): The characteristic of MiC building is that the entire room or space unit (including interior decoration) is completed in the factory.
[0004] However, despite the many advantages of prefabricated construction methods, such as fast construction speed and labor saving, there are still many challenges and problems in the actual operation process. One of the most significant problems is the wide variety of components; for example, in the above two systems, the main components such as beams, columns, and wall panels are all independently manufactured and then transported to the construction site for assembly. Some components even need to be cast on site. Such a system process leads to a high amount of on-site construction, high quality requirements for industry practitioners, and professional training. In addition, the standardized process is complex and the system inertia is large, making it difficult to achieve the goal of fully realizing prefabricated construction, and the assembly efficiency is low and difficult to meet expectations. The second problem is that for concrete wall panels, their own weight is heavy, which brings great difficulty to the installation process, increases construction costs, and has high energy consumption and carbon emissions. The third problem is that the external prefabricated wall panels have the disadvantages of large installation workload, high requirements for waterproofing of board seams, and weak joints, which makes it difficult to avoid quality problems in the later stage. The fourth problem is that MiC buildings face technical challenges such as difficult module transportation and high hoisting costs. Summary of the invention

[0021] The technical effects of the present invention are mainly reflected in the following aspects:
[0022] The present invention integrates the traditional beams, columns and wall panels into an integrated prefabricated wall panel component, which greatly reduces the types of components to be assembled on site, improves the standardization of prefabricated components, reduces the overall weight, and is quick to install. All prefabricated components are flat components, which are convenient for factory production, reduce production costs, improve production efficiency, and ensure production quality. The prefabricated components have a high degree of standardization and commonality. Flat prefabricated components are easy to transport, improve transportation efficiency, and are easy to pass through rural roads. They are easy to store in factories and construction sites. The requirements for construction site lifting equipment are not high. The entire process is bolted for installation, the connection is reliable, the installation is quick, the labor intensity is low, and the installation technology requirements are not high.
[0023] The present invention combines materials of different strengths into an integrated prefabricated wall panel, giving full play to the advantages of each material while effectively avoiding the disadvantages of each material. Specifically, the frame that needs to withstand vertical and horizontal forces is made of reinforced concrete to ensure the structural strength of the wall; the embedded autoclaved aerated concrete board has good thermal insulation performance, improves the energy-saving performance of the building, and reduces carbon emissions. The prefabricated wall panel of the present invention manufactures the autoclaved aerated concrete board and the concrete frame into an integrated prefabricated component in the factory, avoiding the problem of waterproofing the joints of lightweight wall panels during on-site construction.
[0024] The prefabricated composite wall panel composed of an inner page and an outer page with a thermal insulation material in between in the present invention is suitable for use in cold and extremely cold regions. The inner page is made of a high-strength reinforced concrete frame to ensure the basic structural strength of the wall, and an autoclaved aerated concrete board is embedded in the frame; the outer page is an autoclaved aerated concrete board hung on the frame; the thermal insulation material can be rock wool, polystyrene board, etc. Such a combined design not only takes advantage of the high-strength structural advantage of reinforced concrete, but also utilizes the lightweight and thermal insulation properties of the autoclaved aerated concrete board with a certain strength, and the thermal insulation effect is enhanced by the thermal insulation material. The combination of the three allows the present invention to effectively reduce indoor heat loss, maintain a suitable indoor temperature, and reduce heating energy consumption, thereby creating a more comfortable living environment for the residents.
[0025] The present invention adopts bolt connection technology. No matter whether it is the connection between prefabricated wall panels (prefabricated wall panels on the same layer and prefabricated wall panels on the upper and lower layers) or the connection between prefabricated wall panels and other prefabricated components (such as balconies, stairs, etc.), bolts are used for fixing, thereby ensuring the reliability of the structural connection points, simplifying the installation process, avoiding the complex processes of traditional on-site steel bar binding and on-site formwork pouring and concrete connection, and simplifying the separate construction and installation of beams, columns, and wall panels in existing prefabricated buildings into the overall installation of wall panels, thereby reducing the time of on-site operations and reducing labor intensity.
[0026] The bolt connection technology of the present invention can quickly realize the splicing of the right-angle wall and the plane wall of two prefabricated wall panels through the 45° inclined surface design on the vertical frame of the prefabricated wall panel; and the use of U-shaped connecting plates, grouting sleeves and extrusion sleeves makes the longitudinal connection of the upper and lower prefabricated wall panels more convenient. These designs not only improve construction efficiency, but also reduce quality problems caused by improper on-site operations. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] A prefabricated high-strength lightweight frame wall panel, such as Figure 1The prefabricated wall panel with integrated modularity shown in the figure includes a frame 11 made of reinforced concrete to enhance the strength and durability of the overall structure, thereby alleviating the problem of relatively weak strength of the node connection parts of the lightweight wall panel; the frame 11 is embedded with an autoclaved aerated concrete board 12, and the embedded autoclaved aerated concrete board 12 has good thermal insulation performance, which reduces the weight of the wall panel while maintaining sufficient strength. The frame 11 is composed of two vertical frames and two horizontal frames, and the outer sides of the two vertical frames have a vertical 45° inclined surface 13, and the vertical frames are provided with bolt mounting holes 14 that are connected to and perpendicular to the 45° inclined surface 13; the upper and lower end faces of the vertical frame are provided with operating grooves 15, and the operating grooves 15 have visible vertical steel bars 16. The use of autoclaved aerated concrete panels 12 in the prefabricated wall panels is the best solution of the present invention, but there are also cement concrete strips such as concrete hollow wall panels, ceramsite concrete hollow (solid) wall panels, and foam concrete wall panels that have the same appearance and size as the autoclaved aerated concrete panels 12 and are similar in purpose. From the perspective of materials, the raw materials of the above four types of wall panels all have cement and sand. From the perspective of material classification, they are all lightweight concrete strips.

Specifically, the grouting machine injects grout from the grouting hole, and the grouting is completed when the grouting hole of the grouting sleeve 24 overflows and the contact surface of the upper and lower vertical frames also overflows.
[0060] See Figure 5 The connection between the upper and lower layers of prefabricated wall panels shown can also be connected by an extrusion sleeve 23: the prefabricated wall panels also include vertical steel bars 16 visible in the operating groove 15, and the upper and lower steel bars can be inserted into the extrusion sleeve 23; when the upper and lower layers of the two prefabricated wall panels are connected, the vertical steel bars 16 of the upper and lower vertical frames are aligned, inserted into the extrusion sleeve 23 and extruded and connected with tools to achieve the upper and lower layer connection and fixation of the two prefabricated wall panels.
