Description

Technical Field

[0001] This utility model relates to the field of glass curtain walls, and more specifically, to a glass curtain wall anti-impact buffer device. Background Technology

[0002] In glass curtain wall projects, large-sized single-pane glass is often used to meet the requirements of architectural transparency and aesthetics, resulting in a significant increase in weight. However, existing buffer connection structures between the glass and the keel are mostly located on the side of the glass, with the connection direction (horizontal) perpendicular to the glass's own weight direction (vertical). In this structural layout, the glass's weight must be indirectly transferred to the keel through the side connection structure. This causes the connection structure and the load-bearing guide structure used for buffering (such as horizontal guide rails) to bear additional loads perpendicular to their extension direction for extended periods, easily leading to stress concentration. Simultaneously, components such as springs and airbags in the buffer structure not only bear impact cushioning but also indirectly bear part of the glass's weight. After long-term use, these components are prone to fatigue and performance degradation, potentially leading to loosening of the connection structure, bending deformation of the load-bearing guide structure, or even breakage, severely affecting the safety and service life of the curtain wall.

[0003] How to invent an anti-collision buffer device for curtain wall glass to improve these problems has become an urgent problem to be solved by those skilled in the art. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a curtain wall glass anti-impact buffer device, which aims to improve the problem that large-size heavy curtain wall glass, due to the side buffer connection structure being perpendicular to the direction of gravity, causes stress concentration in the connection and load-bearing guide structure under long-term additional load, and the buffer element is prone to fatigue and decay due to bearing gravity, which in turn leads to structural loosening, deformation or even breakage, affecting the safety and service life of the curtain wall.

[0005] This utility model is implemented as follows: A curtain wall glass anti-impact buffer device includes a glass mounting structure and a keel connecting plate. The glass mounting structure includes a fixing frame, and the front surface of the fixing frame has an installation groove in which glass is embedded. The rear side of the fixing frame is provided with a sliding part, which is fixedly connected to the rear surface of the fixing frame by several connectors. A buffer support assembly is fixedly installed on the front surface of the keel connecting plate. The buffer support assembly includes two horizontally extending and parallel horizontal guide rails. The sliding part is slidably installed on the two horizontal guide rails. Each horizontal guide rail has a vertical guide rail integrally provided at its front end. A support wedge block is provided between the two vertical guide rails. The support wedge block is slidably connected to the two vertical guide rails. A linkage wedge block is integrally provided at the bottom end of the rear surface of the fixing frame. The linkage wedge block and the support wedge block are respectively provided with inclined surface structures that can fit together. The support wedge block is connected to the horizontal guide rails through an elastic buffer reset member.

[0006] In a preferred embodiment of this utility model, a plurality of evenly distributed assembly connection parts are integrally provided on the periphery surface of the keel connecting plate.

[0007] In a preferred embodiment of this utility model, a diagonal brace is fixedly connected between the bottom surface of each horizontal guide rail and the front surface of the keel connecting plate.

[0008] In a preferred embodiment of this utility model, a damping device is connected between the glass mounting structure and the keel connecting plate.

[0009] In a preferred embodiment of this utility model, the damping device is a viscous damper.

[0010] In a preferred embodiment of this utility model, a horizontally arranged base plate is fixedly connected to the bottom surface of the supporting wedge block, and one end of an elastic buffer reset member is fixedly connected to the bottom surface of each horizontal guide rail, and the other end of each elastic buffer reset member is fixedly connected to the upper surface of the base plate.

[0011] In a preferred embodiment of this utility model, one end of the inclined surface of the linkage wedge block near the rear surface of the fixing frame is set as a horizontal overlapping surface, and the supporting wedge block is integrally provided with a horizontal support section corresponding to the horizontal overlapping surface, and the upper surface of the horizontal support section abuts against the horizontal overlapping surface.

[0012] In a preferred embodiment of this utility model, the top of each vertical guide rail extends and protrudes above the corresponding horizontal guide rail, and a first anti-collision pad is fixedly installed on the surface facing the horizontal guide rail. Second anti-collision pads are fixedly installed on both sides of the support wedge block and the front surface of the connection between the two vertical guide rails.

[0013] The beneficial effects of this utility model are as follows: The curtain wall glass anti-impact buffer device obtained by the above design, when in use, by setting the inclined surface cooperation structure of the linkage wedge block and the support wedge block, combined with the surface contact design of the horizontal overlapping surface and the horizontal support section, the glass weight is transformed from the traditional side connection transmission to the vertical and inclined support transmission, realizing the sharing of glass weight, avoiding the horizontal connection structure and the load-bearing guide structure (horizontal guide rail) from bearing the entire weight of the glass and generating additional load, reducing the risk of structural deformation or fracture, realizing the buffer function and the weight sharing function, improving the fatigue resistance and service life of the structure, meeting the stable load-bearing requirements of large-size and heavy glass, and ensuring the long-term reliability of the buffer function, thus improving the safety and durability of the glass curtain wall.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Please see Figures 1 to 4This utility model provides a technical solution: a curtain wall glass anti-impact buffer device, including a glass mounting structure 1 and a keel connecting plate 2. The glass mounting structure 1 includes a fixing frame 101, with a mounting groove on the front surface of the fixing frame 101, in which glass 4 is embedded. A sliding part 102 is provided on the rear side of the fixing frame 101, and the sliding part 102 is fixedly connected to the rear surface of the fixing frame 101 by a plurality of connectors 103. A buffer support assembly 3 is fixedly installed on the front surface of the keel connecting plate 2, and the buffer support assembly 3 includes two horizontally extending and parallel horizontal guides. The sliding part 102 is slidably mounted on two horizontal guide rails 301. Each horizontal guide rail 301 has a vertical guide rail 303 integrally provided at its front end. A support wedge block 304 is provided between the two vertical guide rails 303. The support wedge block 304 is slidably connected to the two vertical guide rails 303. A linkage wedge block 104 is integrally provided at the bottom end of the rear surface of the fixing frame 101. The linkage wedge block 104 and the support wedge block 304 are respectively provided with inclined surface structures that can fit together. The support wedge block 304 is connected to the horizontal guide rail 301 through an elastic buffer reset member 307.

[0022] It should be noted that the fixing frame 101 is a metal frame with a mounting groove on the front side adapted to the thickness of the glass 4. After the glass is embedded, it is fixed with sealant. The sliding part 102 is a steel slider, which is connected to the rear surface of the fixing frame 101 through the connector 103. The buffer support assembly 3 is welded to the front side of the keel connecting plate 2. The sliding part 102 is slidably connected to the horizontal guide rail 301 to achieve horizontal sliding. The vertical guide rail 303 is integrally formed or welded to the horizontal guide rail 301. The support wedge block 304 has sliding connection parts on both sides that are adapted to the vertical guide rail 303, which can slide up and down along it. The linkage wedge block 104 is integrally formed with the fixing frame 101. The angle of the inclined surface ensures that when it is in contact with the inclined surface of the support wedge block 304, it can convert the vertical force (the direction of glass gravity) into a horizontal buffer force. The elastic buffer reset part 307 can be a high-strength spring. One end is hooked to the pre-set hanging ear at the bottom of the horizontal guide rail 301, and the other end is connected to the support wedge block 304. When impacted, the spring is stretched / compressed to achieve buffering, and resets after impact.

[0023] Please tell the cashier month Figure 3 and Figure 4 The keel connecting plate has several evenly distributed assembly connection parts integrally formed on its two circumferential surfaces.

[0024] The keel connecting plate is integrally welded around its two circumferences, and the connection can be designed as an ear plate with a slotted hole. During installation, bolts are passed through the slotted hole of the ear plate to connect it to the building keel. The slotted hole can compensate for installation errors and accommodate displacement caused by temperature deformation, ensuring a firm connection. This simplifies the on-site installation process, improves installation accuracy and efficiency, and enhances the connection stability between the device and the building structure, distributing stress and avoiding structural failure caused by localized stress concentration.

[0025] Furthermore, a diagonal brace 302 is fixedly connected between the bottom surface of each horizontal guide rail 301 and the front surface of the keel connecting plate 2.

[0026] The diagonal brace 302 is made of steel round tubing, with one end welded to the bottom of the horizontal guide rail 301 and the other end welded to the front surface of the keel connecting plate 2. The welding position corresponds to the area below the midpoint of the horizontal guide rail, ensuring uniform force transmission and forming a triangular support structure. Utilizing the stability of a triangle, it disperses the vertical load and horizontal impact force borne by the horizontal guide rail, preventing guide rail deformation. This enhances the structural rigidity of the buffer support assembly 3, extends the service life of the guide rail, ensures the smoothness and stability of the glass sliding buffer, and avoids problems such as glass displacement jamming and buffer failure caused by guide rail deformation.

[0027] Furthermore, a damping device is connected between the glass mounting structure 1 and the keel connecting plate 2.

[0028] An installation space is reserved between the glass mounting structure 1 and the keel connecting plate 2. The two ends of the damping device are connected to the fixing frame 101 and the keel connecting plate 2 respectively through hinges. The damper is arranged at an angle or horizontally, which is adjusted according to the installation space. When impacted, the glass causes the fixing frame 101 to shift, and the damping device generates resistance, dissipating the impact energy. This supplements the energy dissipation capacity of the elastic buffer reset component 307, realizing a two-stage buffer of elastic buffering combined with damping energy dissipation, effectively reducing the amplitude and duration of vibration of the glass and structure, improving the impact resistance of the device, and protecting the glass and the main building structure.

[0029] Furthermore, the damping device is a viscous damper 308.

[0030] The viscous damper 308 determines its damping coefficient and stroke based on the glass size, weight, and design impact force. During installation, the connection points between the hinges at both ends of the damper and the fixing frame 101 and the keel connecting plate 2 must ensure that the damper can rotate flexibly with the glass displacement to avoid jamming and ensure stable output of damping force. The linear energy dissipation characteristics of the viscous damper 308, in conjunction with the elastic buffer reset component 307, form a more reasonable response curve, effectively controlling the maximum displacement and acceleration of the glass. Compared with other damping forms, its energy dissipation is more continuous and stable, adaptable to impact conditions of different intensities.

[0031] Furthermore, a horizontally arranged base plate 306 is fixedly connected to the bottom surface of the support wedge block 304, and one end of an elastic buffer reset member 307 is fixedly connected to the bottom surface of each horizontal guide rail 301, and the other end of each elastic buffer reset member 307 is fixedly connected to the upper surface of the base plate 306.

[0032] The bottom of the supporting wedge block 304 is welded to a horizontally arranged base plate 306 via a connecting rod to ensure connection strength. A pre-installed connecting support is located at the bottom of the horizontal guide rail 301. One end of the elastic buffer reset component 307 is hooked to the support, and the other end is hooked to a corresponding hanging point on the upper surface of the base plate 306. The elastic component is directly connected to the supporting wedge block 304, resulting in more precise displacement response, improved buffering efficiency and reset reliability, and ensuring long-term stable operation of the device.

[0033] Furthermore, one end of the inclined surface of the linkage wedge block 104 near the rear surface of the fixing frame 101 is set as a horizontal overlapping surface 105, and the supporting wedge block 304 is integrally provided with a horizontal support section 305 corresponding to the horizontal overlapping surface 105, and the upper surface of the horizontal support section 305 abuts against the horizontal overlapping surface 105.

[0034] A horizontal overlapping surface 105 is machined on one end of the inclined surface of the linkage wedge block 104 near the rear side of the fixed frame 101. A horizontal support section 305, integrally cast, is cast at the corresponding position of the supporting wedge block 304. After installation, the upper surface of the horizontal support section 305 abuts tightly against the horizontal overlapping surface 105, forming surface contact. This disperses the gravity load and prevents wear and deformation caused by localized stress concentration on the inclined surface. Changing from line contact to surface contact improves the stability and reliability of gravity transmission, extends the service life of the wedge block, and ensures the accuracy of the initial state of the buffer mechanism, avoiding buffer function abnormalities caused by the inclined surface detaching.

[0035] Furthermore, the top of each vertical guide rail 303 extends and protrudes above the corresponding horizontal guide rail 301, and a first anti-collision pad 309 is fixedly installed on the surface facing the horizontal guide rail 301. A second anti-collision pad 310 is fixedly installed on both sides of the support wedge block 304 and the front surface of the connection between the two vertical guide rails 303.

[0036] The first anti-collision pad 309 is made of rubber and cut to fit the shape of the top side of the vertical guide rail 303. It is fixed to the top of the vertical guide rail 303 facing the horizontal guide rail 301 by strong adhesive or pre-embedded bolts. The second anti-collision pad 310 is also made of rubber and is attached or fixed to the front surface of the connection between the support wedge block 304 and the vertical guide rail 303. In cases of excessive displacement of the sliding part 102 and the fixing frame 101, the anti-collision pads make contact first, using the elasticity of rubber to absorb energy and buffer the impact, avoiding direct collision between metal parts.

[0037] Working principle: In the initial state, the inclined surfaces of the linkage wedge block 104 and the support wedge block 304 are tightly fitted together, and the horizontal overlapping surface 105 forms surface contact with the horizontal support section 305. The weight of the glass 4 is transferred to the linkage wedge block 104 through the fixing frame 101. The inclined surface of the support wedge block 304 and the horizontal surface of the horizontal support section 305 share the weight of the glass 4 directly borne by the horizontal guide rail 301 through inclined and vertical support, reducing the possibility of deformation of the horizontal guide rail 301 causing displacement obstruction or even breakage. When the glass 4 is subjected to vertical surface impact force, the fixing frame 101 slides along the horizontal guide rail 301 towards the keel connecting plate 2 through the sliding part 102. The linkage wedge block 104 moves synchronously, and its inclined surface pushes the support wedge block 304 to slide downward along the vertical guide rail 303, and the horizontal overlapping surface 105 separates from the horizontal support section 305. When the supporting wedge block 304 descends, the bottom plate 306 connected to the bottom stretches the elastic buffer reset component 307, converting the impact energy into elastic potential energy; simultaneously, the viscous damper 308 generates damping force through internal fluid flow to dissipate energy and suppress the glass displacement velocity. After the impact force disappears, the elastic buffer reset component 307 contracts, causing the bottom plate 306 and the supporting wedge block 304 to reset. The inclined surface of the supporting wedge block 304 pushes the linkage wedge block 104 to move in the opposite direction, causing the glass installation structure 1 to return to its position along the horizontal guide rail 301 until the horizontal overlapping surface 105 and the horizontal support section 305 are re-fitted, restoring the gravity-sharing state. Through the separation of gravity and buffer paths, the guiding and conversion of displacement direction by the inclined surface of the wedge block, and the dual energy dissipation system of elasticity and damping, the problem of guide rail deformation caused by gravity is solved, and efficient buffering and reliable reset are achieved, improving the impact resistance and stability of the curtain wall.

[0038] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
