Description

Technical Field

[0001] The invention relates to a prefabricated assembled exterior wall, in particular to an assembled exterior wall for a large-storey factory building and an installation method thereof. Background Art

[0002] Currently, masonry is commonly used for the exterior walls of high-rise factory buildings (over 6 meters tall). This high height requires the construction of operating platforms, the casting of concrete ring beams between floors, and the casting of structural columns between frame columns. This approach results in a long construction period and high costs.

[0003] Generally speaking, a fast construction method is to use prefabricated assembly, that is, if the wall is made into an assembled component, efficient and safe construction can be achieved. CN117344932A discloses a reinforced concrete and foamed ceramic composite external wall panel and its construction method. It provides a solution of using prefabricated assembled components as the wall, but this solution has several problems. 1. The bottom connection method is used, and under the premise of a high height of the external wall panel, it is easy to fall over; 2. Generally speaking, windows need to be opened on the wall of the factory building, but if this solution is adopted, there will be a problem of nowhere to install the window frame. 3. Even if an area for installing the window frame is reserved in the external wall panel, since the window frame can only be supported by the foamed ceramic panel, the foamed ceramic panel may be damaged. Summary of the Invention

[0004] The purpose of the present invention is to provide an assembled exterior wall for a large-story factory building and an installation method thereof. By being embedded in the frame plane and adapting to factories with large story heights and large column spacing, efficient construction of the exterior wall of a large-story factory building without scaffolding is achieved.

[0005] The present invention is achieved through the following technical solutions: an assembled exterior wall for a large-story factory building, comprising prefabricated wall panels, window frames, and water retaining boards;

[0006] The prefabricated wall piece is extended transversely and includes a lightweight wall panel and a prefabricated outer frame, wherein a plurality of lightweight wall panels are arranged transversely to form a lightweight wall panel group, and reinforced concrete is poured around the outer periphery of the lightweight wall panel group to form a prefabricated outer frame, and the lightweight wall panel group and the prefabricated outer frame together constitute the prefabricated wall piece;

[0007] The prefabricated outer frame is formed by two connecting beams and two connecting columns. At least one vertically extending reinforced concrete reinforcement rib is provided inside the prefabricated outer frame, and both ends of the reinforcement rib are connected to the connecting beam. A positioning notch is provided at the outer edge of the rear side of the middle part of the connecting column. Main anchor plates are embedded at the four top corners of the rear side of the prefabricated outer frame. Lifting embedded parts are provided on the top surface of the prefabricated outer frame and at the positions corresponding to the connecting columns and reinforcement ribs.

[0008] If the prefabricated wall panels are installed from top to bottom in a building frame structure, the building frame structure is formed by structural beams and structural columns or by structural beams, structural columns and the ground; a steel corbel and a secondary anchor plate are installed on the inner wall surface of the structural column, the positioning notch is embedded in the steel corbel, and the secondary anchor plate and the main anchor plate are connected by a connector;

[0009] Wherein, any two adjacent prefabricated wall panels are spaced apart or closely attached; when two adjacent prefabricated wall panels are spaced apart, the window frame is installed between the two adjacent prefabricated wall panels; when two adjacent prefabricated wall panels are closely attached, a lightweight wall panel missing area is provided in some prefabricated wall panels and the window frame is installed in the lightweight wall panel missing area;

[0010] The water retaining plate is installed on the front side of the structural column, and the width of the water retaining plate is greater than that of the structural column to block the gap between the structural column and the prefabricated wall piece.

[0011] A method for installing an assembled exterior wall for a high-rise factory building, characterized by comprising the following steps:

[0012] Step 1, Pre-construction Preparation: Confirm the dimensions of the prefabricated wall panels, the distribution of lightweight wall panels within the prefabricated wall panels, the installation locations of the prefabricated wall panels, and the installation locations of the window frames as required, and lay out steel corbels and auxiliary anchor plates at designated locations on the structural columns of the building frame structure;

[0013] Step 2: Hoisting the prefabricated wall panels: Hoist the prefabricated wall panels to the corresponding positions by hoisting the embedded parts, and push the prefabricated wall panels into the building frame structure so that the positioning notches of the prefabricated wall panels are embedded in the steel brackets. Then, the main anchor plates of the prefabricated wall panels and the secondary anchor plates of the structural columns are welded together by connecting parts;

[0014] Step 3: Install the window frame: When two adjacent prefabricated wall panels are spaced apart, the window frame is installed between the two adjacent prefabricated wall panels. When two adjacent prefabricated wall panels are closely attached, the window frame is installed in the area where the lightweight wall panels are missing from the prefabricated wall panels. Fill the gaps around the window frame with foam glue.

[0015] Step 4: Install waterproof strips: Install a second waterproof strip in the gap between the structural column and the prefabricated wall panel. If two adjacent prefabricated wall panels are closely attached, install a first waterproof strip and a first airtight strip in the gap from the outside to the inside.

[0016] Step 5, install the water retaining plate: install the water retaining plate on the front side of the structural column. The water retaining plate blocks the gap between the structural column and the prefabricated wall panel.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. A positioning notch provided in the middle of the connecting column of the prefabricated outer frame serves as a load-bearing fulcrum for limiting in-plane displacement, and main anchor plates are provided at the four corners of the prefabricated outer frame as non-load-bearing fulcrums for limiting out-of-plane displacement. This allows the prefabricated exterior wall of the present invention to avoid the need to set up an on-site operating frame during construction, thereby enabling the rapid construction of large-height exterior walls.

[0019] 2. The prefabricated exterior frame extends horizontally and is equipped with reinforcing ribs to ensure the strength and rigidity of the prefabricated wall panels, preventing them from being damaged during or after installation. This also provides a guarantee for the installation of window frames. This structure makes it possible to produce prefabricated exterior wall panels according to the column spacing (usually 8-12m).

[0020] 3. The positioning notches of the precast wall panels and the steel brackets on the structural columns enable rapid installation during the hoisting process of the precast exterior frame. The steel brackets serve as load-bearing fulcrums, bearing the weight of the precast wall panels. After installation, the main and secondary anchor plates are welded together to form a single piece, ensuring that the precast exterior wall can withstand horizontal loads and prevent it from falling off.

[0021] 4. The window frame installation method is flexible. It can be installed between adjacent prefabricated wall panels or directly inside the prefabricated wall panels, ensuring design diversity.

[0022] 5. The water retaining board realizes reliable waterproofing at the joints between the structural columns and the prefabricated wall panels. On the premise of setting waterproof strips at the gaps between the components, the overall waterproofness of the exterior wall is further improved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0038] The present invention is described in detail below with reference to the accompanying drawings:

[0039] like Figure 1-4 As shown: An assembled exterior wall for a large-story factory building, including prefabricated wall panels, window frames 3 and water retaining boards 4;

[0040] The prefabricated wall piece is extended horizontally and includes a lightweight wall panel 2 and a prefabricated outer frame 1, wherein a plurality of lightweight wall panels 2 are arranged horizontally to form a lightweight wall panel group, and reinforced concrete is poured around the outer periphery of the lightweight wall panel group to form a prefabricated outer frame 1. The lightweight wall panel group and the prefabricated outer frame 1 together constitute the prefabricated wall piece;

[0041] The prefabricated outer frame 1 is formed by two connecting beams 11 and two connecting columns 12. At least one vertically extending reinforced concrete reinforcement rib 13 is also provided in the prefabricated outer frame 1, and both ends of the reinforcement rib 13 are connected to the connecting beam 11. A positioning notch 14 is provided at the outer edge of the rear side of the middle part of the connecting column 12. Main anchor plates 15 are embedded at the four top corners of the rear side of the prefabricated outer frame 1. Lifting embedded parts 16 are provided on the top surface of the prefabricated outer frame 1, corresponding to the connecting columns 12 and the reinforcement rib 13.

[0042] If the interference wall piece is installed from top to bottom in the building frame structure, the building frame structure is formed by the structural beam 91 and the structural column 92 or by the structural beam 91, the structural column 92 and the ground; a steel corbel 81 and a secondary anchor plate 82 are installed on the inner wall surface of the structural column 92, the positioning notch 14 is embedded in the steel corbel 81, and the secondary anchor plate 82 and the main anchor plate 15 are connected by a connector 17;

[0043] Any two adjacent prefabricated wall panels are spaced apart or closely attached. When two adjacent prefabricated wall panels are spaced apart, the window frame 3 is installed between the two adjacent prefabricated wall panels. When two adjacent prefabricated wall panels are closely attached, a portion of the prefabricated wall panels has a lightweight wall panel missing area, and the window frame 3 is installed in the lightweight wall panel missing area.

[0044] The water retaining plate 4 is installed on the front side of the structural column 92, and the width of the water retaining plate 4 is greater than the structural column 92 to block the gap between the structural column 92 and the prefabricated wall piece.

[0045] Because the prefabricated outer frame 1 is a reinforced concrete structure, it can provide a certain strength for the prefabricated wall panels, ensuring that the internal window frames are not easily damaged during transportation and ensuring the strength after installation. Considering the long distance between the two structural columns in the building frame structure, reinforced concrete reinforcement ribs 13 are installed in the prefabricated outer frame 1 to further ensure the overall strength of the prefabricated wall panels and ensure that the prefabricated outer frame 1 will not crack during the subsequent lifting process or after installation.

[0046] Positioning notches 14 and steel corbels 81 primarily provide support for the precast wall panels. The steel corbels serve as load-bearing fulcrums, bearing the weight of the precast wall panels. Once installed, the primary and secondary anchor plates are welded together to form a single piece, ensuring the precast exterior wall can withstand horizontal loads and prevent collapse.

[0047] Since the prefabricated outer frame 1 is a reinforced concrete structure with reinforcement ribs 13 added to the structure, it can bear the weight of the window frame. The window frame can be installed between adjacent prefabricated outer frames 1 or directly set in the prefabricated outer frame 1 according to needs.

[0048] When two adjacent prefabricated wall panels are closely attached, a water-retaining protrusion 51 is provided on the rear of the upper fitting surface of the prefabricated wall panel, and an inner groove 52 is provided on the rear of the lower fitting surface of the corresponding prefabricated wall panel to match the contour of the water-retaining protrusion 51. This structure is mainly for waterproofing.

[0049] When two adjacent prefabricated wall panels are closely attached, the gap between the two prefabricated wall panels is provided with a first waterproof strip 61 and a first airtight strip 62 from outside to inside. The first waterproof strip 61 mainly plays a waterproof role.

[0050] A second waterproof strip 63 is provided between the structural column 92 and the prefabricated outer frame 1. The first waterproof strip 61 also provides waterproofing. The combination of the first and second waterproof strips 61, 63 allows for joint maintenance during the building's life without affecting interior use.

[0051] The connecting piece 17 is an angle iron. The anchor plate and the auxiliary anchor plate are connected by the angle iron.

[0052] When the window frame 3 is installed between the two adjacent prefabricated wall panels, the space between the window frame 3 and the prefabricated wall panels is filled with foam glue.

[0053] When the window frame 3 is installed in the area where the lightweight wallboard of the prefabricated wall piece is missing, foam glue is filled between the window frame 3 and the lightweight wallboard 2 and the prefabricated outer frame 1 .

[0054] A method for installing an assembled exterior wall for a large-story factory building comprises the following steps:

[0055] Step 1, pre-construction preparation: confirm the size specifications of the prefabricated wall panels, the distribution of the lightweight wall panels 2 within the prefabricated wall panels, the installation positions of the prefabricated wall panels, and the installation positions of the window frames 3 according to the requirements, and lay out the steel brackets 81 and auxiliary anchor plates 82 at the designated positions of the structural columns 92 of the building frame structure;

[0056] Step 2, hoisting the prefabricated wall piece: hoist the prefabricated wall piece to the corresponding position by hoisting the embedded parts 16, and push the prefabricated wall piece into the building frame structure, so that the positioning notch 14 of the prefabricated wall piece is embedded in the steel bracket 81, and then the main anchor plate 15 of the prefabricated wall piece and the auxiliary anchor plate 82 of the structural column 92 are welded together by the connecting piece 17 (such as Figure 5-10 , 13);

[0057] Step 3, install the window frame 3: when two adjacent prefabricated wall panels are spaced apart, the window frame 3 is installed between the two adjacent prefabricated wall panels; when two adjacent prefabricated wall panels are closely attached, the window frame 3 is installed in the area where the lightweight wall panels are missing from the prefabricated wall panels; the gap around the window frame 3 is filled with foam glue (such as Figure 8 、 10 , 13);

[0058] It should be noted that if the window frame 3 is installed in a prefabricated wall panel, the window frame 3 and the lightweight wall panel 2 can be cast together on the prefabricated outer frame 1 at the prefabrication factory before hoisting. However, such a design may cause damage to the window frame during transportation, and additional protective measures must be taken.

[0059] Step 4, install waterproof strips: a second waterproof strip 63 is provided in the gap between the structural column 92 and the prefabricated wall piece; if two adjacent prefabricated wall pieces are closely attached, a first waterproof strip 61 and a first airtight strip 62 are provided in the gap from the outside to the inside (e.g. Figure 11shown);

[0060] Step 5, install the water retaining plate 4: install the water retaining plate 4 on the front side of the structural column 92, and the water retaining plate 4 blocks the gap between the structural column 92 and the prefabricated wall (such as Figure 12 、 14 shown).

[0061] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
