Step type curtain wall fixing structure

Abstract

The invention discloses a step type curtain wall fixing structure, which comprises a first curtain wall plate and a second curtain wall plate which are adjacent to each other and are different in height, and is characterized in that the first curtain wall plate is provided with a first longitudinal extension part facing a wall body, and the second curtain wall plate is also provided with a second longitudinal extension part facing the wall body; and the first longitudinal extension part and the second longitudinal extension part are hung and fixed through a fixing frame arranged on the longitudinal beam. And a necessary deformation space is provided for curtain wall plates which are easy to expand with heat and contract with cold, such as polycarbonate and the like, by adopting split mounting type hanging and fixing. And when the temperature changes, the plates can release thermal stress through mutual extrusion, so that the deformation or tearing risk is remarkably reduced, and the service life is prolonged. The installation process is simple and convenient, and fixation can be completed only by pushing in and falling down depending on gravity.

Description

Technical Field

[0001] This invention relates to the field of building curtain walls, and in particular to a stepped curtain wall fixing structure. Background Technology

[0002] Figure 1 and Figure 2 A novel curtain wall module unit is demonstrated, characterized by a significant difference in thickness between adjacent first curtain wall panels 1 and second curtain wall panels 2 in the direction perpendicular to the wall surface. Figure 3 This demonstrates an existing fixing method: the first curtain wall panel 1 and the second curtain wall panel 2 are respectively locked to the two non-intersecting adjacent sides of a pair of corner brackets 310 and 320 using fasteners. To meet the requirements of lightweight curtain walls, the first curtain wall panel 1 and the second curtain wall panel 2 are typically made of polycarbonate, a material prone to significant thermal expansion and contraction under changes in ambient temperature. The existing fixing method completely locks the curtain wall panels to the corner brackets, which may cause the polycarbonate panels to deform or even tear under extreme weather conditions. In addition, the existing solution leaves a gap 330 between adjacent first curtain wall panels 1 and second curtain wall panels 2, which is covered with sealant 331. Due to the poor weather resistance of the sealant, cracking or peeling is likely to occur after 2-3 years of use. Summary of the Invention

[0003] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A stepped curtain wall fixing structure includes a first curtain wall panel and a second curtain wall panel that are adjacent to each other and have different heights. The first curtain wall panel has a first longitudinal extension portion toward the wall, and the second curtain wall panel also has a second longitudinal extension portion toward the wall. The first longitudinal extension portion and the second longitudinal extension portion are fixed by a fixing bracket set on a longitudinal beam.

[0004] Furthermore, the fixing frame has a U-shaped mounting groove that extends in the same direction as the longitudinal beam, and the first longitudinal extension portion and the second longitudinal extension portion are tightly fitted together and inserted into the mounting groove.

[0005] Furthermore, the fixing frame is provided with a hanging component, the rod of the hanging component passes through the mounting groove, and L-shaped hanging grooves are provided on both the first longitudinal extension portion and the second longitudinal extension portion. The hanging and fixing is achieved by pushing the hanging groove into the rod.

[0006] Furthermore, a threaded structure is provided on the outer circumferential surface of the rod, and a nut that engages with the threaded structure is provided on the second side of the fixing frame.

[0007] Furthermore, both the first and second curtain wall panels are made of polycarbonate.

[0008] Furthermore, it also includes: a first support frame for fixing the longitudinal beam, the first support frame being a sub-frame; and a second support frame, the second support frame being a main load-bearing frame surrounding the first support frame.

[0009] Furthermore, the first support frame is a 40 aluminum frame, and the second support frame is an 80 aluminum frame.

[0010] The beneficial effects of this invention are as follows: The stepped curtain wall fixing structure provided by this invention adopts a modular hanging fixing method, providing necessary deformation space for curtain wall panels such as polycarbonate that are prone to thermal expansion and contraction. When the temperature changes, the panels can release thermal stress through mutual compression, thereby significantly reducing the risk of deformation or tearing and extending service life. Its installation process is simple; fixing is completed simply by pushing it in and relying on gravity to fall. Attached Figure Description

[0020] In the specification, when an element is described as being "on," "fixed" to, "connected" to, or "joined" to another element, the element may be directly located on, fixed to, connected to, joined to, or in contact with the other element, or there may be an intermediate element present. In the specification, the description of a feature being arranged "adjacent" to another feature may refer to a feature having a portion that overlaps with the adjacent feature or a portion located above or below the adjacent feature.

[0021] It is understood that although the terms "first," "second," etc., may be used herein to describe different elements, these elements should not be limited by these terms. These terms are merely used to distinguish one element from another. Therefore, a first element may be referred to as a second element without departing from the teachings of this application.

[0022] Exemplary embodiments of this application will now be described with reference to the accompanying drawings. However, it should be understood that this application can be presented in many different ways and is not limited to the embodiments described below. It should also be understood that the embodiments disclosed herein can be combined in various ways to provide further additional embodiments. Throughout the drawings, the same reference numerals denote the same or functionally identical elements.

[0023] Figure 4 and Figure 5 This invention showcases a novel assembly and fixing structure for a stepped curtain wall, comprising a longitudinal beam 300 fixed to a first, laterally extending support frame 100 and a fixing bracket 340 fixed to the longitudinal beam 300. The longitudinal beam 300 extends at a 90° angle to the first support frame 100. The fixing bracket 340 has a U-shaped cross-section and a U-shaped recessed mounting groove 341, which extends in the same direction as the longitudinal beam 300. A hanger 342 is also fixed to the fixing bracket 340. The rod 344 of the hanger 342 is inserted into the fixing bracket 340 from the first side 340a, passes through the mounting groove 341, and exits from the second side 340b. The outer circumferential surface of the rod 344 is threaded and locked by a nut 343 from the second side 340b.

[0024] The curtain wall module is assembled from a first curtain wall panel 1 and a second curtain wall panel 2. Both the first and second curtain wall panels 1 and 2 have inwardly extending first and second longitudinal extension portions 1a and 2a, respectively, with mounting grooves 3 formed on these portions. From a side view, the mounting grooves 3 are L-shaped. The first and second longitudinal extension portions 1a and 2a fit tightly together and are inserted into the mounting groove 341, pushing the rod 344 into the opening of the mounting groove 3. As the first and second curtain wall panels 1 and 2 fall under gravity, the rod 344 moves with the mounting groove 3 to its deepest point, thus achieving fixation.

[0025] In some embodiments, the first curtain wall panel 1 and the second curtain wall panel 2 are made of polycarbonate.

[0026] The beneficial effect of this fixing structure is that by tightly fitting the longitudinal extensions of the first curtain wall panel 1 and the second curtain wall panel 2 together into the mounting groove 341 of the fixing frame 340, the visible gaps reserved to cope with thermal expansion and contraction in traditional solutions are effectively reduced, making the curtain wall appearance cleaner and more continuous. Since the adjacent panels are assembled and fixed rather than completely rigidly locked, necessary deformation space is provided for curtain wall panels such as polycarbonate that are prone to thermal expansion and contraction. When the temperature changes, the panels can release stress through mutual compression, greatly reducing the risk of deformation or tearing caused by thermal stress and extending the service life of the curtain wall. At the same time, the assembly method of this structure is simple; the hanging and fixing can be completed by pushing in and gravity dropping.

[0027] Reference Figure 6 Furthermore, it also includes a second support frame 200 as the main load-bearing frame, and the first support frame 100 is placed within the frame enclosed by the second support frame 200.

[0028] In some implementations, the first support frame 100 is a 40 aluminum frame and the second support frame 200 is an 80 aluminum frame.
