Description

Technical Field

[0001] This utility model belongs to the field of wall panel installation technology, and in particular relates to an installation structure for prefabricated exterior wall panels. Background Technology

[0002] Precast exterior wall panels are typically made of concrete, lightweight materials, or other composite materials, and are prefabricated in factories or on-site. They offer advantages such as thermal insulation, heat insulation, fire resistance, lightweight construction, and environmental friendliness. Depending on the raw materials and structural form used, precast exterior wall panels can be categorized into various types, such as GRC (glass fiber reinforced cement) wall panels, PCW (polyester gypsum board), and PSF (steel wire mesh sandwich molded profiles). Currently, with the increasing demands for green building and energy conservation and emission reduction, as well as rising labor costs, new composite insulation wall panels are widely used in modern construction projects to replace traditional brick masonry methods.

[0003] Currently, polyurethane sandwich insulation panels are commonly used as exterior wall panels in steel structure workshops. During installation, these panels are directly fixed to the frame with screws, and then installed sequentially from top to bottom. Most existing exterior wall panels use a snap-fit ​​structure on both sides for connection. While this traditional structure offers precise positioning, ease of installation, and strong stability, it doesn't allow for effective replacement of individual panels after installation. Replacing a damaged panel requires removing all the panels above it sequentially, which is labor-intensive, cumbersome, inefficient, and risks damaging intact panels above, leading to uncontrollable construction costs. Therefore, we propose a prefabricated exterior wall panel installation structure to address these issues. Summary of the Invention

[0004] In view of this, in order to solve the problem that traditional installation structures are not conducive to the disassembly and replacement of a single wall panel, this utility model provides an installation structure for prefabricated exterior wall panels.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an installation structure for a prefabricated exterior wall panel, comprising an exterior wall panel body, wherein two upper connecting parts are symmetrically arranged on the top two sides of the exterior wall panel body, and a lower connecting part is arranged at the bottom middle position of the exterior wall panel body, and a mating space is formed between the two upper connecting parts to fit and engage with the lower connecting part.

[0006] The installation structure also includes an installation strip, which is used to simultaneously limit and abut against the two upper and lower connecting parts. Two positioning elements are symmetrically fixed on the inner side of the installation strip. The two positioning elements are fixedly connected to the keel with the fixing screws to achieve synchronous positioning of the upper and lower connecting parts, thereby completing the fixed installation of the exterior wall panel body. In addition, the fixed installation of the exterior wall panel body by the positioning elements can be used for the disassembly and replacement of a single exterior wall panel body.

[0007] Furthermore, the positioning element includes a positioning tube fixedly disposed on the inner side of the mounting strip, and a semi-circular groove for cooperating with the positioning tube is provided on the side of the two upper connecting parts that are close to each other, and an arc-shaped notch for cooperating with the positioning tube is provided on the side of the lower connecting parts that are far from each other.

[0008] Furthermore, the outer side of the mounting strip is symmetrically provided with two first T-shaped holes that communicate and cooperate with the corresponding positioning tubes. The first T-shaped holes are used for the installation of fixing screws.

[0009] Furthermore, two locking strips are symmetrically fixed on the inner side of the mounting strip, and the outer sides of the two upper connecting parts are provided with locking grooves that are positioned and engaged with the corresponding locking strips.

[0010] Furthermore, two second T-shaped holes are symmetrically opened on the outer side of the mounting strip, and a connecting screw is inserted to complete the fixed connection between the mounting strip and the two upper connecting parts.

[0011] Furthermore, the lower connecting part has a through hole on its side, and the mounting strip has a perforation corresponding to the through hole on its side.

[0012] Furthermore, the length of the through hole is greater than the length of the perforation.

[0013] The embodiments of this utility model have the following beneficial effects: This invention achieves precise alignment between two upper connecting parts and one lower connecting part through their cooperation. Furthermore, the fixing of the mounting strip to the keel provides simultaneous limiting and resisting effects for both the upper and lower connecting parts, thus achieving synchronous positioning and fixing of the two exterior wall panels. The entire installation structure is simple to operate, offers strong connection stability, and allows for the removal and replacement of individual exterior wall panels after installation by disassembling the mounting strip. This effectively reduces the amount of work and improves construction efficiency, while eliminating the need to sequentially remove other intact exterior wall panels, thus avoiding the risk of damage.

Detailed Implementation

[0017] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of this utility model. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0018] Example 1: Please refer to Figures 1-8 This embodiment provides an installation structure for a prefabricated exterior wall panel, including an exterior wall panel body 10. Two upper connecting portions 101 are symmetrically and integrally provided on the top of the exterior wall panel body 10. Both upper connecting portions 101 are close to the inner edge of the exterior wall panel body 10, allowing for close-fitting installation with the keel. The sides of the two upper connecting portions 101 that are furthest from each other are flush with the sides of the exterior wall panel body 10 that are furthest from each other. A lower connecting portion 102 is provided at the bottom center of the exterior wall panel body 10, also close to the inner edge of the exterior wall panel body 10, allowing for close-fitting installation with the keel. A certain length of gap exists between the two upper connecting portions 101, forming a mating space 103, which is perfectly matched to the length and width of the lower connecting portion 102. When the upper and lower exterior wall panel bodies 10 are installed together, the lower connecting part 102 can be precisely engaged within the mating space 103 formed between the two upper connecting parts 101, thus ensuring precise alignment of the two exterior wall panel bodies 10 and guaranteeing that both sides of the wall panel are on the same horizontal line, preventing installation misalignment and maintaining a consistent width of the longitudinal wall joint. The upper connecting part 101 and the lower connecting part 102 have the same height and width, with the height matching the height of the reserved horizontal joint between the two exterior wall panel bodies 10, while the width does not exceed half the overall width of the exterior wall panel body 10.

[0019] In one aspect of this embodiment, to facilitate the fixed installation of the exterior wall panel body 10 onto the keel frame, the installation structure also includes an installation strip 20 for limiting and abutting the two connecting parts 101 and 102. Two positioning tubes 202 are symmetrically fixed on the inner side of the installation strip 20, that is, on the side that limits and abuts the upper connecting parts 101 and 102. The positioning tubes 202 can be integrally formed or welded to the installation strip 20. Two first T-shaped holes 201 are symmetrically opened on the outer side of the installation strip 20 to communicate and cooperate with the corresponding positioning tubes 202. Semicircular slots 1011 are opened on the sides of the two upper connecting parts 101 that are close to each other. When positioning the exterior wall panel body 10, the mounting strip 20 can be positioned through the positioning tube 202 and passed through the semi-circular groove 1011, abutting against the outer side of the upper connecting part 101. This ensures that the inner side of the exterior wall panel body 10 and the end of the positioning tube 202 away from the mounting strip 20 both abut against the keel. Then, the fixing screw 30 is passed through the first T-shaped hole 201 and the positioning tube 202 and fixedly connected to the keel. The screw head of the fixing screw 30 abuts against the first T-shaped hole 201, completing the fixing of the mounting strip 20 and limiting the contact of the upper connecting part 101, thus achieving the fixed installation of the exterior wall panel body 10. The positioning insertion of the positioning tube 202 into the semi-circular groove 1011 provides a positioning effect for the mounting strip 20, ensuring that both ends of the mounting strip 20 are flush with the sides of the two upper connecting parts 101 that are far apart, preventing misalignment. Simultaneously, it facilitates the installation of the fixing screw 30, ensuring stability during installation.

[0020] Furthermore, arc-shaped notches 1021 are provided on the opposite sides of the lower connecting portions 102. When the upper exterior wall panel body 10 is aligned with the lower exterior wall panel body 10, and the lower connecting portion 102 is aligned between the two upper connecting portions 101, a positioning docking space 103 is formed between the mounting strip 20 and the two upper connecting portions 101 because the lower exterior wall panel body 10 has been pre-fixed using the mounting strip 20. The lower connecting portion 102 can achieve precise alignment between the two exterior wall panel bodies 10 vertically through this docking space 103, ensuring not only the horizontal alignment between the two sides of the exterior wall panel body 10 but also the horizontal alignment of the outer side of the exterior wall panel body 10. In addition, when the exterior wall panel body 10 is placed from top to bottom, it can be precisely engaged with the outer wall of the positioning tube 202 through the arc-shaped notches 1021, thus completing the alignment.

[0021] When installing the bottom outer wall panel body 10, the installation strip 20 can be fixed to the keel frame by fixing screws 30 through the positioning marks. Then, the outer wall panel body 10 is positioned and overlapped on the two positioning tubes 202 through the lower connecting part 102 for preliminary positioning. Then, the upper installation strip 20 is installed to complete the fixed installation of the bottom outer wall panel body 10.

[0022] When installing the uppermost exterior wall panel 10, the mounting strip 20 can be left unsecured initially. Instead, use manual labor or support rods to provide auxiliary support for the adjacent lower exterior wall panel 10. Then, install the uppermost exterior wall panel 10 by pushing it horizontally (if there is no pre-reserved space at the top, i.e., installation from top to bottom is not possible) and align it with the keel. Finally, insert the mounting strip 20 to secure the exterior wall panel 10. During the horizontal pushing process, the interlocking of the arc-shaped notch 1021 and the positioning tube 202 will not affect the installation of the exterior wall panel 10. Furthermore, this method allows for easy replacement of individual exterior wall panels 10 if any becomes damaged later. The damaged panel can be removed from both the top and bottom mounting strips 20, the damaged panel removed, and a new panel can be pushed in and installed. Finally, the mounting strip 20 can be reinstalled, enabling the replacement of a single exterior wall panel 10 and improving practicality.

[0023] This utility model can be used in the field of installation structure of prefabricated exterior wall panels, and can also be applied to other fields of this utility model.

[0024] Example 2: This example is a further improvement on the previous example: as follows Figures 1-8 As shown, two retaining strips 203 are symmetrically fixed on the inner side of the mounting strip 20. The retaining strips 203 can be integrally formed or welded. A retaining groove 1012 is provided on the outer side of each of the two upper connecting parts 101, and the retaining groove 1012 engages with the retaining strip 203 for positioning. When the mounting strip 20 is positioned against the outer side of the upper connecting part 101, the retaining strip 203 can be engaged in the retaining groove 1012, further improving the positioning and installation of the mounting strip 20, and simultaneously improving the fit between the upper connecting part 101 and the lower connecting part 102.

[0025] In one aspect of this embodiment, two second T-shaped holes 205 are symmetrically formed on the outer surface of the mounting strip 20, and the two second T-shaped holes 205 are respectively formed at both ends of the mounting strip 20. After the mounting strip 20 is fixed and abuts against the upper connecting part 101, a connecting screw 40 can be passed through the second T-shaped hole 205 to connect with the upper connecting part 101. The screw head of the connecting screw 40 also directly abuts against the second T-shaped hole 205, thereby completing the fixation between the two ends of the mounting strip 20 and the two upper connecting parts 101 respectively. This can effectively prevent the two ends of the mounting strip 20 from warping outward due to deformation, and at the same time enhance the stability of the outer wall panel body 10, thereby further improving the stability of the installation.

[0026] Example 3: This example is a further improvement on the previous example: as follows Figures 1-8As shown, a through hole 1022 is provided on the side of the lower connecting part 102, and a through hole 204 corresponding to the through hole 1022 is provided on the side of the mounting strip 20, with the length of the through hole 1022 being greater than the length of the through hole 204. After the mounting strip 20 is in limiting contact with the upper connecting part 101 and the lower connecting part 102, a fitting effect can be achieved. When the exterior wall panel body 10 is damaged and needs to be replaced, the mounting strip 20 needs to be removed first. First, remove the fixing screws 30 and connecting screws 40. Since the gap between the upper and lower exterior wall panel bodies 10 is small, a tool, such as a long hook, can be used to first pass through the through hole 204, then hook the entire inner side of the mounting strip 20, and then pull it outward to pull out the mounting strip 20. If it is deformed, simply replace it with a new mounting strip 20, thus facilitating the removal of the mounting strip 20.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of this technical solution, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
