Description

Technical Field

[0001] This utility model relates to the field of curved curtain wall structure technology, and in particular to a prefabricated curved curtain wall structure with reserved deformation space. Background Technology

[0002] With the development of modern architectural aesthetics, curved and arc-shaped designs are increasingly used on building facades. Prefabricated curtain walls have become the mainstream construction method due to their advantages such as factory production, quick on-site installation, and easy quality control.

[0003] However, when applying prefabricated technology to curved curtain walls, the problems of thermal stress and structural deformation still exist. Specifically, traditional curved curtain walls often use rigid connections or simple glue seals between unit panels. Under the influence of environmental factors such as temperature changes, wind loads, and earthquakes, the curtain wall support structure will experience certain displacement and deformation. The rigidly connected unit panels cannot effectively absorb these deformations, resulting in stress concentration or even cracking of the glass or panels. The sealant is also torn, causing potential water leakage. Therefore, we propose a prefabricated curved curtain wall structure with reserved deformation space. Utility Model Content

[0004] In view of the problems of thermal stress and structural deformation in the existing prefabricated curved curtain wall structures, this utility model is proposed.

The side of the curved unit panel has a lateral folded edge that bends inward toward the curtain wall. The joint mechanism includes a male profile, a female profile, and a sealing strip. The male profile and the female profile are respectively installed on two adjacent lateral folds and interlock to form a cavity. The sealing strip is installed at the interlocking joint of the male profile and the female profile. A reserved deformation groove is formed in the cavity in a direction perpendicular to the curtain wall surface. The width L of the reserved deformation groove is 15mm to 40mm.

Detailed Implementation

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] Reference Figures 1-6 A prefabricated curved curtain wall structure with reserved deformation space is provided. This prefabricated curved curtain wall structure with reserved deformation space includes multiple curved unit panels 1, a connecting mechanism 2 for fixing the curved unit panels 1 to the main structure, and a joint mechanism 3 set between two adjacent curved unit panels 1. The side of the curved unit panel 1 has a lateral flange 101 that bends inward toward the curtain wall. In application, the lateral flange 101 that bends inward toward the side of the curved unit panel 1 enhances the edge stiffness of the curved unit panel 1 and provides a stable mounting base for the joint mechanism 3. The joint mechanism 3 includes a male profile 301, a female profile 302, and a sealing strip 303. The male profile 301 and the female profile 302 are respectively installed on two adjacent lateral folds 101 and interlock to form a cavity 304. The sealing strip 303 is installed at the interlocking joint of the male profile 301 and the female profile 302. A reserved deformation groove is formed in the cavity 304 in a direction perpendicular to the curtain wall surface. The width L of the reserved deformation groove is 15mm to 40mm. In application, the cavity 304 formed by the interlocking of the male profile 301 and the female profile 302, with a reserved deformation groove of 15-40mm, allows the curtain wall to expand and contract freely under temperature and wind loads, avoiding stress concentration that could cause panel cracking or glue joint tearing. At the same time, the sealing strip 303 covers the interlocking joint, forming a physical and airtight barrier to reduce the risk of leakage.

[0023] Reference Figure 1 , Figure 2 as well as Figure 4 The connecting mechanism 2 includes a support 201 fixed to the main structure and a connecting bolt 203 fixed to the arc-shaped unit plate 1. The support 201 has an elongated hole 202 (hole length ≥ 30mm). The connecting bolt 203 is threadedly connected to a connecting nut 204. The connecting bolt 203 is installed on the support 201 through the elongated hole 202 and the connecting nut 204. Adjustment gaps are provided between the support 201 and the connecting bolt 203 in three dimensions. In application, the elongated hole 202 on the support 201 cooperates with the connecting bolt 203 to realize the planar adjustment of the installation position, and the connecting nut 204 provides height fine adjustment. The design of the three-dimensional adjustment gap can compensate for construction errors and structural deformation to improve installation accuracy and adaptability.

[0024] Reference Figure 1 , Figure 2 as well as Figure 5 The curved unit panel 1 can be a curved glass panel, a curved metal panel, or a curved artificial board panel. In application, it is clear that the curved unit panel 1 can be glass, metal plate, or artificial board, thus broadening the scope of application of the technology to adapt to different building appearance requirements.

[0025] Reference Figure 2 and Figure 3 The male profile 301 is provided with a guide hook 3011 at its end, and the female profile 302 is provided with a slot 3021 that is adapted to the guide hook 3011. The female profile 302 is installed on the male profile 301 through the slot 3021 and the guide hook 3011. In application, the guide hook 3011 on the male profile 301 and the slot 3021 on the female profile 302 are plugged in to install, which simplifies the on-site assembly process, ensures the fastening accuracy, and reduces human error.

[0026] Reference Figure 2 and Figure 3The sealing strip 303 is a hollow Ω-shaped strip, such as a hollow Ω-shaped EPDM rubber strip. In application, the hollow structure of the Ω-shaped sealing strip 303 gives the strip high elasticity and compression rebound ability to adapt to repeated deformation and maintain sealing performance for a long time.

[0027] Reference Figure 5 and Figure 6 The bottom of the cavity 304 is provided with a drainage hole 305. In application, the drainage hole 305 at the bottom of the cavity 304 can drain the rainwater that seeps in in time, which can prevent water accumulation from corroding the profile or causing damage from frost heave, thereby extending its service life.

[0028] The working principle of this utility model is as follows: Main structure positioning and support 201 installation stage: First, position the support 201 on the main structure (such as steel beam, concrete wall) according to the construction drawings, and fix it by welding or anchor bolts to ensure that the distance error between adjacent supports 201 is ≤2mm. Then, adjust the three-dimensional position of the support 201 and reserve the adjustment gap (5mm in the horizontal / vertical direction and 3mm in the thickness direction is recommended). The hoisting and initial fixing stage of the arc-shaped unit plate 1: hoist the arc-shaped unit plate 1 to the design position, pass the connecting bolt 203 through the elongated hole 202 on the support 201, and do not tighten the connecting nut 204 temporarily to keep the arc-shaped unit plate 1 in a fine-adjustable state; Assembly stage of joint mechanism 3: First, fix the male profile 301 to the lateral fold 101 on an arc-shaped unit plate 1 with screws, and fix the female profile 302 to the lateral fold 101 on the adjacent arc-shaped unit plate 1. Then, push the adjacent arc-shaped unit plate 1 horizontally so that the guide hook 3011 on the male profile 301 slides into the slot 3021 on the female profile 302 to form a cavity 304. At the same time, check the width of the deformation groove (L=15–40mm). Finally, insert the sealing strip 303 into the fastening joint. Three-dimensional precision adjustment and locking stage: First, use tools (such as laser instruments) to check the flatness of the curtain wall surface, and eliminate errors by adjusting the position of the connecting bolt 203 in the elongated hole 202 (horizontal displacement), the height of the connecting nut 204 (vertical displacement), and the gap of the support 201 (thickness direction). After confirming that there are no errors, tighten the connecting nut 204 and spot weld it to prevent loosening, and at the same time lock the connecting screws of the profiles (male profile 301, female profile 302).

[0029] Drainage and sealing test phase: Water is injected into cavity 304 to verify the unobstructedness of drainage hole 305, and at the same time, a water spray test is conducted on sealing strip 303 to ensure no leakage.
