Description

Technical Field

[0001] This utility model belongs to the technical field of general building curtain wall construction under IPC classification E04B2 / 88, and particularly relates to an improved curtain wall structure technology with multi-angle broken line structure and effect, which is applicable to the field of architectural decoration. Background Technology

[0002] The zigzag unitized glass curtain wall is a special type of unitized glass curtain wall, characterized by its zigzag shape. It consists of multiple unit panels arranged in a zigzag pattern on a plane or in space, breaking the monotony of traditional straight-line curtain walls and adding a unique visual effect and dynamic aesthetic to the building facade. It is often used in projects that pursue unique architectural styles and shapes.

[0003] With continuous innovation in architectural design, zigzag unitized glass curtain walls are being used more and more widely in buildings due to their unique appearance.

[0004] Currently, there is a small amount of publicly available research and application in the field of zigzag unitized glass curtain wall technology.

[0005] Patent application 202322308215.7 discloses a folded glass curtain wall system, including a transition structure and glass panels arranged in a folded line. The outer corners of the glass panels are fixed by structural adhesive. The transition structure includes a main body and an inner corner limiting structure at the ends. The inner corner limiting structure includes a steel plate in the middle. An inverted L-shaped connector and a first limiting member are fixed to the upper end of the steel plate. The first limiting member is fixed to the steel plate by bolts. This application uses the transition structure to fix three sides of the glass panel to the steel plate keel. Then, the remaining side of the glass is fixed to the adjacent glass forming the folded line by structural adhesive. Finally, it is sealed with an aluminum plate.

[0006] In the existing technology, the design and installation of folded-line unitized glass curtain walls, especially multi-angle folded-line unitized glass curtain walls, in the field of building exterior decoration can usually only be achieved by manufacturing aluminum alloy keels with different specific angles and special components for upper and lower horizontal folded lines, and then custom-installing and assembling the multi-angle folded-line unitized glass curtain walls with specific structures. This traditional manufacturing and installation method has a complex manufacturing process and high cost.

[0007] The existing technology has the following drawbacks:

[0008] In existing technologies, multi-angle zigzag unitized glass curtain walls are adjusted and fixed by manufacturing aluminum alloy keels at different angles. However, due to numerous influencing factors during construction, the accuracy of installation positioning cannot be guaranteed. Therefore, it is necessary to design a new connection system structure that meets the architectural design requirements for the appearance of multi-angle glass curtain walls while ensuring safety, reliability, and ease of installation. Utility Model Content

[0009] To solve the above problems, this utility model designs a multi-angle zigzag unit glass curtain wall connection structure. Through the point and surface intersection construction design, it can easily achieve adjustment of different angles, which not only meets the architectural design requirements for the appearance of multi-angle glass curtain walls, but also ensures safety, reliability and convenient installation.

[0010] To address this, this utility model provides a multi-angle zigzag unitized glass curtain wall connection structure. On the exterior facade of the building, specifically the front facade of the main structure, adjacent sections are fixedly extended forward with a longer steel structural keel and a shorter U-shaped steel member. Glass panels are installed on both sides of the front end of the longer steel structural keel via aluminum alloy vertical frames, forming a forward-protruding angled curtain wall unit. Glass panels are installed on both sides of the front end of the shorter U-shaped steel member via unit male and female vertical frames, forming a rear-protruding angled curtain wall unit. Unit male and female vertical frames are installed between the front end of the steel structural keel and the front end of the shorter U-shaped steel member, forming a sloped transition connecting curtain wall unit. Adjustable telescopic transition structures are provided at the front ends of both the steel structural keel and the U-shaped steel member to allow for adjustable forward and rearward protrusion angles of the curtain wall. Through the aforementioned connection structure, multiple sets of continuous forward-protruding angled curtain wall units, sloped transition connecting curtain wall units, and rear-protruding angled curtain wall units constitute a multi-angle zigzag unitized glass curtain wall.

[0011] The front end of the steel structure keel is connected to the H-shaped aluminum alloy adapter via the aluminum alloy central vertical bracket and the second connecting bolt. The front end of the H-shaped aluminum alloy adapter is connected to the aluminum alloy central vertical frame via the first connecting bolt. The rear of the H-shaped aluminum alloy adapter is fitted with a first eye-shaped pad and a second connecting bolt, which connects to the aluminum alloy central vertical bracket. The H-shaped aluminum alloy adapter is connected to the aluminum alloy central vertical bracket via the first eye-shaped pad and the second connecting bolt. A second eyeglass-shaped pad is installed at the front end of the U-shaped steel component and connected to the Z-shaped anti-jump component via the third connecting bolt. The front end of the Z-shaped anti-jump component is connected to the male and female vertical frames of the unit via aluminum alloy brackets.

[0012] Furthermore, to achieve the above objectives, this utility model is configured as follows:

[0013] In particular, an aluminum backing plate is installed behind the glass panel mounted on the vertical frame of the aluminum alloy; another set of aluminum backing plates is installed on the front facade of the male and female vertical frames of the unit, and thermal insulation rock wool board is installed behind this set of aluminum backing plates.

[0014] In particular, the H-shaped aluminum alloy adapter has an H structure, which is composed of two vertically hinged plates with corresponding holes at both ends connected together in the middle front side. The front side (short end) of the H-shaped aluminum alloy adapter has corresponding round holes on the outer wall, and the rear side (long end) of the H-shaped aluminum alloy adapter has corresponding elongated holes on the outer wall.

[0015] In particular, the vertical hanger in the aluminum alloy has a fork-shaped structure, with a hinge hole in the middle of the front of the vertical hanger and a U-shaped fork seat at the rear with a corresponding opening at the rear end.

[0016] In particular, the first eye-shaped pad and the second eyeglass-shaped pad are vertical plate structures with two horizontal through holes that are parallel to each other at the top and bottom, and with straight holes that are longitudinally opened in the middle or at the top and bottom.

[0017] In particular, the aluminum alloy hanger is a parallel vertical two-piece clamping plate structure connected together by a vertical perforated base plate on the rear bottom side, and a connecting hole is opened at the front edge of the two vertical clamping plates, and a limiting latch structure is formed by protruding downward at the rear bottom edge of the two vertical clamping plates.

[0018] In particular, the U-shaped steel component is a channel steel structure. A second spectacle-shaped pad is inserted between the openings at the front end of the U-shaped steel component and the corresponding elongated slots on the vertical outer walls on both sides. A third connecting bolt is then inserted through the transverse inner hole.

[0019] In particular, the Z-shaped anti-jump component includes a Z-shaped perforated curved noodle plate, that is, fastening holes are opened on the upper outward edges on both sides and the bottom middle of the Z-shaped anti-jump component 16.

[0020] In particular, the aluminum alloy cover plate, the aluminum alloy middle vertical frame, and the unit male and female vertical frames are mutually compatible profiles. Specifically: the front end of the aluminum alloy middle vertical frame has a tapered outer edge, with an adjusting screw at the top of the outer end of this tapered outer edge. Rotating the adjusting screw allows adjustment of the tilt angle at which the glass panel is mounted on the front end of the aluminum alloy middle vertical frame; a slot is provided next to the adjusting screw, into which the glass panel and sealant filler are embedded. The rear edge of the aluminum alloy cover plate is folded inward and snaps onto the outer side of the tapered outer edge of the front end of the aluminum alloy middle vertical frame. The front of the unit male and female vertical frames has a Y-shaped structure. The unit male and female vertical frames include two male and female frame structures with mutually compatible edges, which are aligned and snapped together at the middle and rear of the unit male and female vertical frames and then locked at the rear end between the rear openings of the aluminum alloy hanger.

[0021] In particular, a block-shaped keel support is fixedly installed on the lower side of the front facade of the steel structure keel before it extends out from the main building structure.

[0022] This utility model facilitates easy adjustment and positioning, and allows for quick construction. The eye-shaped pad frame design supports multi-angle installation and adjustment. To ensure reliable connection of the vertical hangers in the aluminum alloy system, the eyeglass-shaped pad frame and adjusting bolts transmit force, achieving structural safety and making the system stable and reliable. The H-shaped aluminum alloy adapter connects to the vertical keel in the aluminum alloy system via connecting bolts, facilitating assembly and ensuring connection strength while simplifying adjustment. Furthermore:

[0023] 1) Flexible angle adjustment: Through the structural design of point and surface intersection, it can effectively adapt to various complex changes in angle of broken line, improving the flexibility of curtain wall design; and easily realize the adaptive adjustment of curtain wall installation at different angles.

[0024] 2) Easy installation: The connection between the components is simple, which facilitates construction and can effectively improve construction efficiency and shorten the construction period.

[0025] 3) High stability: Limiting and anti-jumping components are set in the installation structure to ensure the stability and reliability of the connection, and improve the overall safety and service life of the curtain wall.

[0026] 4) The structure has been optimized and improved, with close coordination between components, accurate positioning, enhanced sealing of connections, and improved performance of the curtain wall. This ensures the structural safety of the multi-angle glass curtain wall, high system installation precision, a stable and reliable structure, and balances economic practicality with aesthetic appeal.

Detailed Implementation

[0033] It should be noted that:

[0034] In the description of this utility model, unless otherwise expressly specified and limited, the terms "comprising" and "having," and any variations thereof, are intended to cover other possible options under the same logic not listed. For example, a process, method, system, product, or device comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such process, method, product, or device. The terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationships commonly used when the utility model product is in use. They are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the utility model. Furthermore, the terms "first," "second," "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance. Furthermore, terms such as "horizontal," "vertical," and "suspended" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," not that the structure must be completely horizontal, but can be slightly tilted. The terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components.

[0035] Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. In case of any conflict, the definitions in this specification shall prevail.

[0036] In this invention, from a structural design perspective, to adapt to the changing shape of the zigzag curve, the construction of the unit panels is more complex and diverse, requiring consideration of factors such as angle variations between panels, connection methods, and sealing performance. Regarding material selection, in addition to conventional glass and aluminum alloy profiles, materials with special properties may be used to meet the mechanical and functional requirements of different parts of the zigzag structure. In terms of construction and installation technology, due to the irregular geometry of the zigzag curtain wall, higher requirements are placed on installation precision and construction processes, necessitating more accurate measurement and positioning techniques to ensure the overall quality and aesthetic appearance of the curtain wall.

[0037] The connection structure of the zigzag-shaped unitized glass curtain wall has certain limitations when dealing with multi-angle changes. For example, the connection structure has poor adaptability and cannot meet the needs of different angle combinations of zigzags; the stability and sealing of the connection are difficult to guarantee under complex angle conditions; the installation process is relatively cumbersome, affecting construction efficiency, etc. Therefore, a new type of connection structure is needed to solve these problems.

[0038] The principle of this utility model is as follows:

[0039] 1) Connection component design: This connection structure includes a special connector with multiple adjustable connection points, capable of being adjusted according to different polygonal angles. For example, a rotatable and telescopic connector is used, and through precise mechanical design, it can freely change angles within a certain range to adapt to various complex polygonal combinations.

[0040] 2) Sealing Measures: High-performance sealing materials and structures are used at the connection points. A multi-layered sealing design, such as a combination of elastic sealing strips and sealant, ensures effective prevention of rainwater and air penetration at different connection angles, thus improving the curtain wall's sealing performance.

[0041] 3) Optimized Installation: The design features a convenient installation method, with modular connectors for easy and rapid assembly on-site. Detailed installation markings and positioning devices are also provided, enabling installers to accurately and quickly complete the installation of the connection structure, thus improving construction efficiency.

[0042] This utility model mainly includes aluminum alloy hangers, U-shaped steel parts, eyeglass-shaped pads, connecting bolts, unit male and female vertical frames, Z-shaped anti-jump parts, H-shaped aluminum alloy adapters, and aluminum alloy central vertical hangers, etc.

[0043] This utility model innovatively optimizes the connection system of multi-angle zigzag unit glass curtain walls, reliably solves architectural design problems, takes into account appearance requirements, ensures safety and reliability, and is easy to install, saving time and being highly efficient.
