Description

Technical Field

[0001] This invention belongs to the field of building decoration technology, specifically relating to a GRC component installation structure and installation method. Background Technology

[0002] High-rise buildings, due to their unique shapes, undergo fundamental changes in technical rationality, functional diversity, and economic feasibility as the number of stories and height increase, thus increasing the complexity and difficulty of high-rise construction. Therefore, many buildings tend to use prefabricated GRC (Glass Fiber Reinforced Concrete) components when constructing their facades. However, the installation technology, construction operability, and structural stability of GRC components have always been technical challenges that the construction industry urgently needs to solve. Traditional installation methods mainly rely on direct anchoring with expansion bolts and back-welded steel frame support, which has the following problems: 1. The drilling process for expansion bolts can easily lead to the propagation of microcracks in the concrete, weakening the structural cross-section. When encountering areas with dense reinforcement, the drill bit is very likely to break the main reinforcement or stirrups, causing irreversible damage to the main structure. Furthermore, expansion bolt connections have low installation precision and significant errors, making accurate installation of GRC components impossible. In addition, expansion bolts may experience anchorage failure, leading to GRC detachment.

[0003] 2. The post-installed steel frame has a large steel section and is heavy, requiring segmented hoisting, positioning, and welding at high altitudes. It is subject to both wind loads and tower crane swaying, resulting in a short working window and prolonged worker exposure to edge openings, posing a high risk of fall. Furthermore, the steel frame has poor durability; prolonged exposure to the environment makes it prone to corrosion, reducing the structure's safety. Maintenance requires erecting a suspended platform for rust removal and repainting, leading to high ongoing maintenance costs. Summary of the Invention

Slide grooves are opened on the profile slide rails, and connecting holes are opened on the connecting plates. The components are then connected by bolt and nut connectors. During the connection process, the bolt and nut connectors can slide within the slide grooves to adapt to the GRC components, thereby achieving precise installation of the GRC components.

[0037] See Figures 1-9 This application provides a GRC component installation structure 100, mainly used for installing GRC components 200 on a building wall 300. Both ends of the GRC component 200 are connected to the corresponding side of the wall 300 through the GRC component installation structure 100, as shown in the figure. The GRC component installation structure 100 mainly includes a profile slide rail 110, a connecting plate 120, and a bolt and nut connector 130. The profile slide rail 110 has a groove 111 along its length. One end of the connecting plate 120 is fixed to the end of the GRC component 200, and the other end has a connecting hole. The bolt and nut connector 130 includes a bolt 131 and a nut 132, used to fix the profile slide rail 110 and the connecting plate 120 through the groove 111 and the connecting hole. The profile slide rail 110 can be pre-embedded in the wall 300, and the connecting plate 120 is pre-fixed to the end of the GRC component 200. During use, the GRC component 200 is hoisted to the installation position, aligning the connecting plate 120 with the profile slide rail 110. The profile slide rail 110 and connecting plate 120 are then initially fixed using bolt and nut connectors 130. Further adjustments to the overall position of the GRC component 200 are made by sliding the bolts 131 (i.e., the GRC component 200 and connecting plate 120) within the slide groove 111. After confirming there are no abnormalities, the bolt and nut connectors 130 are tightened to lock and secure the component. This connection structure, through the design of the slide groove 111, allows for adaptive adjustment of the GRC component 200 via sliding, thereby achieving precise installation of the GRC component 200.

[0038] See Figure 2In some embodiments, the back of the profile slide rail 110 also has a pre-embedded rib 140, which is pre-embedded in the wall 300 as a whole with the profile slide rail 110 to enhance the connection firmness.

[0039] Furthermore, we use stirrups as embedded bars 140 on the construction site, which are welded to the back of the profile slide rail 110. The stirrups can be arranged horizontally or vertically.

[0040] See Figure 3 , Figure 4 , Figure 5 In some embodiments, at least one notch 112 is provided at the slide groove 111. When installing the GRC component 200, the installer passes the nut portion of the bolt 131 through the notch 112 and slides it to the corresponding position within the slide groove 111. Then, the connecting hole of the connecting plate 120 is fitted onto the bolt 131, and finally, the nut 132 is screwed onto the bolt 131, thus initially fixing the GRC component 200 to the profile slide rail 110. Compared to existing installation methods, the installation process is simpler and more convenient, and also facilitates fine-tuning of the GRC component 200.

[0041] See Figure 6 In some embodiments, the two side walls inside the profile slide rail 110 each have a first slot plate 113. The two first slot plates 113 are arranged in parallel and symmetrically, and a sliding channel is formed between the two first slot plates 113. During installation, the nut part can be slid into the sliding channel. The nut part can slide in the sliding channel, but cannot rotate. The nut part can slide in the sliding channel to meet the fine adjustment of the GRC component 200. The nut part is stuck in the sliding channel and cannot rotate, which makes it convenient to screw the nut 132 onto the bolt 131 and tighten it, making the operation simpler.

[0042] Furthermore, the end of the sliding channel is configured in a "flared" shape (not shown in the figure) to facilitate the sliding of the nut part from the flared opening into the sliding channel.

[0043] Furthermore, we can also use hexagonal flange bolts (bolt 131), such as... Figure 6 Hexagonal flange bolts mainly consist of an integrally formed hexagonal head, a flange, and an externally threaded bolt. The diameter of the inscribed circle of the hexagonal head is slightly smaller than the width of the sliding channel, while the diameter of the circumscribed circle is larger than the width of the sliding channel. This ensures that the bolt can only slide within the sliding channel and cannot rotate. Furthermore, the diameter of the flange is larger than the width of the sliding channel, allowing it to be secured between the first slot plate 113 and the profile slide rail 110, preventing the hexagonal flange bolt from falling out. During use, the hexagonal flange bolt can be secured between the first slot plate 113 and the profile slide rail 110, eliminating the need for manual support and simplifying operation.

[0044] See Figure 7 In some embodiments, the profile slide rail 110 is equipped with a pair of L-shaped second slot plates 114, forming a sliding channel between the pair of L-shaped second slot plates 114. The sliding channel is aligned with the slide groove 111. The nut 132 is installed inside the sliding channel and can slide within it. The inscribed circle diameter of the nut 132 is slightly smaller than the width of the sliding channel, and the circumscribed circle diameter of the nut 132 is larger than the width of the sliding channel, to meet the requirement that the nut 132 can only slide within the sliding channel and cannot rotate. In use, the nut 132 is located in the sliding channel, eliminating the need for manual assistance from the construction worker. Simply pass the bolt 131 through the connecting hole and the slide groove 111 in sequence, and then screw it onto the nut 132, freeing up one hand of the construction worker (for assistance) and making the connection operation simpler.

[0045] Furthermore, at least one slot 112 can be provided at the slide groove 111, so that during installation, the nut 132 can be pre-installed into the sliding channel through the slot 112. Alternatively, the nut 132 can be pre-installed in the sliding channel.

[0046] Furthermore, the end of the sliding channel is configured in a "flared" shape (not shown in the figure) to facilitate the sliding of the nut 132 from the flared end into the sliding channel.

[0047] See Figure 8 In some embodiments, the profile slide rail 110 has a built-in slider 115, and a nut 132 is fixedly installed on the slider 115, with the nut 132 aligned with the slide groove 111. During installation, the installer first slides the slider 115 along its length within the profile slide rail 110 until the nut 132 aligns with the connecting hole. Then, the bolt 131 is passed through the connecting hole and the slide groove 111 in sequence and screwed onto the nut 132 to complete the initial connection. Since the slider 115 can only slide along its length within the profile slide rail 110, the installer only needs to tighten the bolt 131 to complete the connection and locking, making it more convenient to use. Specifically, as shown... Figure 8 As shown, the slider 115 can be made of a profile slightly smaller than the profile slide rail 110, and the nut 132 can be connected to the slider 115 by welding.

[0048] This application, through progressive optimization of various solutions, from improvements to the basic connection structure to detailed installation processes, effectively solves the problems of cumbersome construction, long cycle, and insufficient reliability of expansion bolts in traditional GRC installation. It is suitable for rapid connection scenarios between GRC components and the main structure in various building decoration projects, and has high practical value and promising prospects for promotion.

[0049] See Figure 8 In some embodiments, the GRC member 200 has at least one bend, specifically... Figure 8In the illustrated embodiment, the GRC component 200 has three bends: a first bend 210 located in the middle, and second and third bends 220 and 230 located at both ends. By providing bends on the GRC component 200, in addition to enhancing its aesthetic appeal, it also provides a certain amount of expansion and contraction, preventing the risk of detachment caused by tensile forces resulting from structural deformation, and also providing some tolerance during installation.

[0050] See Figure 1-9 Another embodiment of this application provides a GRC component installation method, based on the GRC component installation structure 100 described in any of the above embodiments, specifically including: S100: construction preparation; S200: installation of GRC component 200; S300: sealing of profile slide rail 110.

[0051] Step S100 includes: S101: The profile slide rail 110 has dimensions of 150mm in length, 44mm in width, and 38mm in height, with a rectangular slot 112 formed on it, measuring 30mm in length and 17mm in width. Since the top of the profile slide rail 110 needs to remain parallel to the structural surface during the pre-embedding process, a stirrup support method is used. The GRC component 200 involved in this application is custom-made, with a zigzag shape, bending inwards in the middle of the GRC (bending section), the bending length of which is determined according to the size of the GRC component 200.

[0052] S102: After the profile slide rail 110 and the stirrups are processed, the stirrups are welded and fixed on the back of the profile slide rail 110. After the welding is completed, end caps are installed at both ends of the profile slide rail 110, and the grooves 111 and openings 112 of the profile slide rail 110 are sealed with tape to prevent concrete from entering the interior of the profile slide rail 110 during subsequent construction.

[0053] S103: The connecting plate 120 involved in this application is 120mm long and 16mm wide. At one end of the connecting plate 120, a rectangular installation hole (i.e., connecting hole) 30mm long and 10mm wide is cut from the end of the connecting plate 120 with the length centerline as the center, and the connecting plate 120 is bent into a right angle. When prefabricating the GRC component 200, the uncut end of the connecting plate 120 is pre-embedded in the GRC component 200, while the end with the hole is installed facing the outside of the GRC component 200.

[0054] Step S200 includes: S201: Before structural construction, the installation position of GRC component 200 is determined by measuring and setting out according to the design drawings of GRC component 200, and the stirrups are connected with the installation position of connecting plate 120 as the center.

[0055] S202: After the profile slide rail 110 is installed, its position and elevation must be checked again to ensure they meet the design requirements. The binding of the stirrups must also be thoroughly checked to ensure there is no loosening or misalignment. The construction site should then be cleaned up, and excess materials and tools removed to prepare for the subsequent concrete pouring process.

[0056] S203: During the wall pouring process, a designated person should monitor the status of the profile slide rail 110. If any signs of displacement or deformation are found, the pouring operation should be suspended and corrected to ensure that the position and elevation of the profile slide rail 110 meet the requirements. Concrete pouring personnel should reasonably control the vibration spacing and duration to ensure concrete compaction while avoiding concentrated concrete accumulation and contact between the tamping rod and the profile slide rail 110, thus minimizing the impact on the profile slide rail 110. After the concrete strength reaches the design standard, the formwork should be removed, and any concrete residue adhering to the top of the profile slide rail 110 should be cleaned, and the tape in the operating hole should be removed.

[0057] S204: Use lifting equipment to smoothly hoist the GRC component 200 to the designated installation position. During hoisting, ensure the stability of the component and avoid swaying or tilting. Adjust the specific position of the GRC component 200 to precisely align the mounting opening (connection hole) of the connecting plate 120 with the profile slide rail 110. Insert the nut into the slide groove 111 through the slot 112 of the profile slide rail 110, and pass the bolt 131 through the slide groove 111 and the mounting opening in sequence. Lift the bolt 131 by hand and put the nut 132 on, and initially fix it with the nut 132.

[0058] Step S205: After all mounting points on the GRC component 200 are initially secured with nuts 132, the overall position of the GRC component 200 is further adjusted by sliding it along the profile slide rail 110. During the adjustment process, the horizontality and verticality are checked. After confirming that there are no abnormalities, the nuts 132 are fully tightened, thus completing the fixation of the entire GRC component 200. After the GRC component 200 is securely fixed, check whether the nut connections are tight to avoid safety hazards in subsequent use due to loosening.

[0059] Step S300 includes: S301: After the GRC component 200 is installed and fixed, inject cement mortar with a strength higher than that of the wall concrete into the profile slide rail 110 to enhance the connection strength between the GRC component 200 and the wall concrete. After the cement mortar has completely cured, apply anti-rust paint to the exposed metal parts.

[0060] In summary, the beneficial effects of this application include: 1. By simultaneously welding the 300mm steel mesh in the wall with the stirrups and profile slide rails 110, the problem of secondary drilling and structural damage required by traditional post-anchoring is solved. This allows for simultaneous construction of the main structure and the GRC component 200, shortening the construction period. It also solves the problem of the need to install a steel frame on the back of the GRC component 200, which involves complex installation procedures and high construction risks, reducing the time spent working at heights during installation and improving safety.

[0061] 2. By replacing the traditional point-type expansion bolt anchoring with continuous anchoring of the profile slide rail 110 (achieved through the slide groove 111), the problems of anchoring failure of expansion bolts and GRC panel detachment are solved. The load is evenly transferred to the main structure (wall 300) along the length of the profile slide rail 110, which significantly improves the wind resistance and long-term safety of the GRC external system.

[0062] 3. By incorporating bends in the GRC components' 200mm exterior design, the problem of GRC deformation and cracking caused by stress or minor structural settlement during installation is resolved. This achieves stress buffering and extends the component's service life. Simultaneously, the bend design visually enhances the building's facade's layering and three-dimensionality, improving the overall decorative effect.

[0063] 4. By adding the first slot plate 113, the problem of bolt 131 being prone to deflection and not being firmly fixed when installed in the slide groove 111 is solved. The bolt 131 can form a stable engagement structure with the inner wall of the profile slide rail 110 through the first slot plate 113, which improves the convenience of bolt 131 installation and connection reliability in high-altitude operations.

[0064] 5. By setting a second slot plate 114 inside, the problem of limited construction flexibility caused by the need for rotation and locking operation of nut 132 in a narrow space during installation is solved. This allows nut 132 to move freely along the length direction within the profile slide rail 110, simplifies the alignment process of bolt and nut connector 130, and improves the convenience and efficiency of installation.

[0065] 6. By adopting the method of welding the nut 132 and the slider 115 into one piece, the problems of easy sliding and insufficient positioning accuracy of the nut 132 when installed in the profile slide rail 110 are solved. This ensures that the nut 132 remains stable during installation and avoids affecting the screwing in of the bolt 131 due to positional displacement. At the same time, the structure of welding the nut 132 and the slider 115 can effectively disperse the stress concentration at the bolt 131 connection part and enhance the load-bearing capacity of the node.
