[0002] With the advancement of technology and the growing adoption of low-carbon and environmentally friendly concepts, prefabricated building structures are becoming increasingly common in modern architecture. Prefabricated buildings shift much of the traditional on-site construction work to the factory floor. Components and accessories (such as floor slabs, wall panels, stairs, and balconies) are manufactured in the factory, transported to the construction site, and assembled and installed on-site using reliable connections.

[0003] In the current structural construction of most prefabricated buildings, traditional construction methods such as formwork, pouring and demoulding are still required after the installation of prefabricated components to ensure the integrity and stability of the structure. In addition, the insulation layer and finishing layer of the wall need to be installed later. This will undoubtedly increase the construction process and affect construction efficiency. The increase in construction processes may even cause secondary pollution to the building and the environment. Utility Model Content

[0004] The utility model provides an integrated wall structure of an assembled building, which is used to solve the shortcomings of the prior art, such as the need to carry out formwork, pouring and demoulding processes after the installation of prefabricated components, and then install the insulation layer and finishing layer of the wall at a later stage, which increases the construction process and affects the overall integrity of the building structure.

[0032] The following combination Figure 1-Figure 5 The embodiments of the present invention are described.

[0033] like Figure 1-Figure 5As shown, this embodiment provides an integrated wall structure for a prefabricated building, comprising interior panels 200, exterior panels 100, and a grid frame 300. The interior panels 200 and exterior panels 100 are spliced ​​and laid on both sides of the grid frame 300. A concrete filling layer 400 is poured within the cavity formed by the interior panels 200, exterior panels 100, and grid frame 300, forming an integrated structure with the interior panels 200, exterior panels 100, and grid frame 300. Based on the frame structure, the interior panels 200 and exterior panels 100 serve as a formwork that does not need to be disassembled, and together with the concrete filling layer 400, they form a wall, achieving a cast-in-place construction of the wall with its own interior and exterior layers. In this embodiment, the concrete filling layer 400 can also be made of ordinary concrete or lightweight concrete. The use of lightweight concrete can maintain the integrity of the building. At the same time, due to its light weight, high strength, thermal insulation, shock resistance and anti-seepage characteristics, it can save multiple construction processes such as later decoration and insulation, thereby improving construction efficiency.

[0034] The keel grid 300 provided in this embodiment includes two rows of parallel vertical frames 310. A plurality of crossbeams 320 can be fixed between the two rows of vertical frames 310. A plurality of transverse reinforcement bars 330 can be fixed to the crossbeams 320 to ensure the integrity and stability of the frame structure. The crossbeams 320 can also be provided with slots into which the transverse reinforcement bars 330 can be inserted. The slots constrain the installation position of the transverse reinforcement bars 330, simplifying the installation of the transverse reinforcement bars 330 and increasing the speed of manufacturing the keel grid 300.

[0035] In this embodiment, the exterior panel 100 is provided with a bolt hole 110 on the side near the vertical frame 310. The exterior panel 100 is secured to the vertical frame 310 via a bolt structure 500. The interior panel 200 can also be secured to the vertical frame 310 via the bolt structure 500 or a threaded structure. This allows the interior panel 200, the exterior panel 100, and the keel grid 300 to form a relatively stable whole, and also serves as a longitudinal reinforcement within the keel grid 300. Unlike conventional bolt-on dry-hanging structures, the bolt structure 500 used in this embodiment consists solely of expansion bolts and nuts, eliminating the ear-hanging structure found in conventional bolt-on dry-hanging structures. Instead, C-shaped channel steel is used as the vertical frames 310. The notches of two rows of vertical frames 310 are aligned relative to each other, and fastening holes 311 corresponding to the expansion bolts are directly provided at the bottom of the grooves of the vertical frames 310. Tighten one end of the expansion bolt into the back bolt hole 110, and pass the other end through the fastening hole 311 and fasten it to the vertical frame 310 with a nut, thus ensuring the integrity and integrity between the exterior panel 100 and the keel grid 300. Furthermore, thread fasteners can be applied to the connections between the expansion bolt, the vertical frame 310, the interior panel 200, and the exterior panel 100 to prevent loosening during the subsequent pouring of the concrete filler layer.

[0036] In the integrated wall structure provided in this embodiment, masking paper can also be provided at the gaps where the exterior panels 100 and the interior panels 200 are spliced ​​and laid, which can be used to prevent the concrete filling layer from overflowing from the gaps during pouring and can also beautify the wall.

[0037] When constructing the integrated wall structure provided in this embodiment, the keel grid 300 can be constructed first. First, two rows of vertical frames 310 are arranged along the wall, and then transverse reinforcement bars 330 are laid on the crossbeams 320 to complete the overall framework. The interior panels 200 and exterior panels 100 can then be fixed to both sides of the keel grid 300 using the back bolt structure 500. This serves as a non-removable formwork for the building structure and also acts as a longitudinal reinforcement, reinforcing the keel grid 300. After the interior panels 200 and exterior panels 100 are laid, a concrete filling layer 400 can be poured into the cavity formed by the interior panels 200, exterior panels 100, and keel grid 300. After waiting for curing, the construction process of the integrated wall structure is completed.

[0038] In this embodiment, the exterior trim 100 is preferably made of stone-like ceramic panels, which can be customized with various textures and colors, such as stone and paint, and possesses multiple properties, including high flexural strength, strong impact resistance, acid and alkali resistance, corrosion resistance, fire resistance, and easy cleaning. The interior trim 200 is preferably made of fiberglass boards, which offer excellent heat and moisture resistance, good workability, and can be used as a soft-cover base layer, allowing fabric, leather, and other materials to be directly wrapped on top to create a beautiful wall surface.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
