Description

Technical Field

[0001] The invention relates to the technical field of special-shaped curved panels, and in particular to an installation method for a special-shaped large-curved glass fiber reinforced cement exterior wall panel. Background Art

[0002] In recent years, with the continued rapid development of my country's construction industry, city skylines have been constantly reshaped, and the design concept of building facades has undergone a profound shift from a functional to an aesthetically pleasing approach. Against this backdrop, exterior wall decoration is no longer limited to traditional flat paving or simple shaping, but is evolving towards personalized, artistic, and dynamic designs. Specially shaped, large-surface glass fiber reinforced cement (GRC) exterior wall panels, with their unique curved aesthetics and excellent mechanical properties, have rapidly become the material of choice for high-end construction projects. However, the installation process of these panels faces technical bottlenecks such as difficult precision control, lengthy processes, and frequent splicing defects due to the complexity of the curved surface. Balancing "design aesthetics" and "construction feasibility" has become a critical issue that the industry urgently needs to address. Summary of the Invention

[0003] In order to solve the above problems, the present invention provides a method for installing special-shaped large-curved glass fiber reinforced cement exterior wall panels, which can achieve rapid installation of exterior wall panels while ensuring the reliability of installation quality.

[0023] Example 1

[0024] like Figures 1 to 3 As shown, the present invention provides a method for installing special-shaped large-curved glass fiber reinforced cement exterior wall panels, which specifically includes the following steps:

[0025] Step 1: Level the base layer and clean the surface of the exterior wall where the exterior wall panel 1 is to be installed. At the same time, square the structure, find the rules, pop out the vertical and horizontal lines, and pop out the positioning lines of the embedded parts according to the design drawings and actual needs. The cleaning of the exterior wall surface should mainly remove dust and scum to ensure the flatness of the exterior wall.

[0026] Step 2: Install the embedded parts and keel 3. Install the embedded parts according to the positioning line and perform a pull-out test. Weld the keel 3 and the embedded parts according to the layout position of the construction layout drawing. First install the keels 3 at both ends of the same facade, and then install the middle keel 3 in sequence by pulling the line through.

[0027] Step 3: Install the exterior wall panel 1. First, pre-embed the connecting steel bars 8 on the exterior wall panel 1. Weld the back-attached steel frame 2 onto the connecting steel bars 8. The upper and lower parts of the back-attached steel frame 2 are respectively provided with upper hanging connectors 4 and lower plug connectors 5. The keel 3 is respectively provided with an upper mounting hole plate 6 and a lower mounting groove 7 that cooperate with the upper hanging connector 4 and the lower plug connector 5. The exterior wall panel 1 is connected to the keel 3 by an upper hanging and lower plug method. The whole operation process is simple, effectively improving the construction efficiency and saving the construction cost.

[0028] Step 4: Adjust and fix. After the exterior wall panel 1 is installed, adjust the horizontality and verticality. After the adjustment is completed, fix the upper hanging connector 4 to the upper mounting hole plate 6 with bolts, and fix the lower plug connector 5 to the lower mounting groove 7 with marble glue. The horizontality is adjusted by placing a copper wire pad between the upper hanging connector 4 and the upper mounting hole plate 6 to make the upper edge of the exterior wall panel 1 flat. The verticality is adjusted by adjusting the gap between the exterior wall panel 1 and the exterior wall.

[0029] Step 5: Gluing and cleaning: Glue the flat seams of the exterior wall panel 1 and clean the exterior wall panel 1.

[0030] Specifically, in step three, before installing the exterior wall panels 1, the panels are pre-planned using a building information model (BIM). Pre-embedded openings for connecting rebar 8 are pre-set and numbered horizontally and vertically along the exterior wall, from right to left and from bottom to top. Pre-planning the exterior wall panels 1 using a building information model (BIM) allows for visualization of complex nodes and pre-reservation of each required opening location, further improving installation efficiency and reducing construction costs.

[0031] Specifically, in step 3, two adjacent exterior wall panels 1 are subjected to edge grinding and corner clamping processing to ensure that the joints between the two adjacent exterior wall panels 1 are straight and even without skew, misalignment or edge damage.

[0032] Specifically, in step 3, the exterior wall panel 1 on the upper portion of the exterior wall is hoisted using a crane and a tower crane, and the exterior wall panel 1 is transported up and down using a hanging basket. A foam board is installed on the side of the hanging basket that is close to the wall to prevent the exterior wall panel 1 from colliding. When the exterior wall panel 1 is transported using a hanging basket, the exterior wall panel 1 may shake during transportation. To ensure that the exterior wall panel 1 does not collide with the exterior wall, it is essential to install the foam board on the hanging basket.

[0033] Specifically, in step five, a hydrophobic coating is sprayed on the cleaned exterior wall panel 1 to achieve a waterproof effect.

[0034] In addition to the above-mentioned preferred embodiments, the present invention has other implementation modes. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection requested by the present invention.
