Description

Technical Field

[0001] This invention relates to the field of building door and window safety protection technology, specifically to a reinforcement device that can be quickly disassembled and installed without damage, for improving the wind pressure resistance of building doors and windows such as sliding doors and windows under extreme weather conditions. Background Technology

[0002] The widespread use of large-area glass doors and windows in urban high-rises and coastal buildings brings advantages in lighting and views, but also exposes them to significant risks during typhoons and other strong winds. Existing wind-resistant reinforcement solutions mainly fall into two categories: one is permanent methods such as welding and drilling bolt fixing, which, while reliable in strength, damages the building structure and is irreversible, affecting aesthetics and daily use; the other is temporary products such as windproof panels and simple suction cups, which often suffer from low structural strength, incomplete load-bearing systems, poor versatility, and inconvenience in storage.

[0003] Therefore, existing solutions cannot simultaneously meet the comprehensive requirements of high wind resistance, completely non-destructive installation, rapid and flexible disassembly and assembly, and wide adaptability to various scenarios. The fundamental reason lies in the lack of a systematic design concept that can modularize anchoring, force transmission, and load distribution functions, and construct an efficient and detachable load transfer path from the surface of doors and windows to the main body of the building. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] The technical problem to be solved by this invention is: how to overcome the shortcomings of the prior art and provide a modular wind-resistant reinforcement device that can be quickly installed and disassembled without damaging the structure of doors, windows and walls, and has sufficient wind resistance and wide adaptability to size and profile, so as to safely and conveniently meet the protection needs of various doors and windows under extreme wind pressure.

[0006] (II) Technical Solution

[0007] To solve the above-mentioned technical problems, the present invention provides a detachable wind-resistant reinforcement device for doors and windows, comprising:

[0008] At least two connecting components, wherein the connecting components are U-shaped fixing clips for clamping door and window profiles or flat fixing bases for fixing to the wall;

[0009] At least one reinforcing crossbar, the two ends of which are detachably connected to the connecting components located on both sides;

[0010] At least one intermediate connecting mechanism, the intermediate connecting mechanism including a suction cup assembly and / or a sub-beam with contact components; the intermediate connecting mechanism is detachably and positionally adjustable and mounted on the reinforcing crossbar;

[0011] The intermediate connecting mechanism is used to adsorb or support the surface of the door and window through its contact parts, and transfer the wind pressure load to the reinforcing crossbar, and further distribute it to the door and window profiles or the main body of the building through the connecting components, thereby forming a detachable force transmission path between the door / window and the main body of the building.

[0012] Preferably, the contact component is a suction cup or a cushioning pad.

[0013] Preferably, the suction cup assembly includes a suction cup, a lead screw, and an adjusting nut and a wing nut for locking the lead screw to the reinforcing crossbar.

[0014] Preferably, the sub-beam is adjustablely mounted on the reinforcing crossbar via a connector; the connector is an extended wing bolt, and the sub-beam is provided with a welded long nut that mates with it; or the connector includes a hinged bolt assembly.

[0015] Preferably, the U-shaped fixing clamp includes a clamp body, a screw, and a damage-preventing disc, and has a single-point or double-point locking structure.

[0016] Preferably, the reinforcing crossbar is a hollow tubular structure with connecting through holes, or a telescopic structure with a large tube inside a small tube.

[0017] Preferably, the sub-beam is fixed to the reinforcing crossbar by a double-hole connecting piece and an extended wing bolt.

[0018] (III) Beneficial Effects

[0019] Compared with the prior art, the detachable wind-resistant reinforcement device for doors and windows provided by the present invention has the following significant advantages:

[0020] 1. Completely non-destructive installation: It adopts mechanical clamping, adsorption or top pressing methods, without the need for any drilling, welding or bonding on doors, windows or walls, perfectly protecting the integrity and aesthetics of the original structure.

[0021] 2. Systematic Improvement in Wind Resistance: Through modular design, a highly efficient load transfer chain is constructed, consisting of "intermediate connecting mechanism → reinforcing crossbar → connecting components." This design gathers and transfers the dispersed wind pressure acting on the surface of doors and windows to the reinforcing crossbar, which is ultimately borne by the anchor points, thereby significantly suppressing the overall deformation, vibration, and risk of detachment of doors and windows.

[0022] 3. Excellent modularity and adaptability: It offers two anchoring methods, U-shaped clips and flat bases, as well as various intermediate connection solutions such as direct adsorption, sub-beam adsorption, and sub-beam top support. Users can flexibly select and combine modules according to specific door and window types, profile specifications, installation environment, and wind speed, achieving wide adaptability to diverse scenarios such as sliding doors and casement windows.

[0023] 4. Ultimate convenience and reusability: All connection points use standardized fasteners that can be operated manually or with simple tools, making the installation process intuitive and quick. After disassembly, the main components can be compactly stored, facilitating transportation and long-term reuse.

[0024] 5. Higher safety redundancy: The combination of multiple intermediate connecting mechanisms arranged in a distributed manner with the rigid main crossbar forms a multi-path force transmission system, which improves the reliability of the device under extreme conditions.

[0099] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention.

[0100] Example 1: Direct Adsorption

[0101] See Figure 1 , Figure 3 , Figure 4 and Figure 5 The device in this embodiment mainly includes two connecting components (single nut U-shaped fixing clamp), a reinforcing crossbar, and multiple suction cup components.

[0102] The connecting assembly (single nut U-shaped fixing clamp) includes a clamp body (2), a screw (3), and a damage-preventing disc (4). By rotating the screw (3), the damage-preventing disc (4) can be driven to press against the surface of the door frame profile to achieve fixation. The damage-preventing disc (4) can rotate freely at the end of the screw (3) to avoid scratching the profile.

[0103] The reinforcing crossbar (45) has through holes (9, 15) at both ends. During installation, the screw (3) passes through the through holes (9, 15) of the connecting component and the reinforcing crossbar (45) in sequence, and is locked by the wing nut (5), thereby fixing the reinforcing crossbar (45) between the two connecting components.

[0104] The suction cup assembly includes a suction cup (8), a lead screw (7), an adjusting nut (6), and a wing nut (5). The lead screw (7) passes through the through holes (10-14) on the reinforcing crossbar (45), and the suction cup (8) adheres to the glass or frame surface. By adjusting and locking the adjusting nut (6) and the wing nut (5), a reliable connection between the suction cup assembly and the reinforcing crossbar (45) can be achieved, thereby transferring the wind pressure load to the reinforcing crossbar.

[0105] Example 2: Adsorption type with sub-beam (sub-beam is located on the outside of the reinforcing crossbar)

[0106] See Figure 6 , Figure 7 , Figure 8 and Figure 9 This embodiment introduces a secondary beam structure based on embodiment 1 to distribute the stress.

[0107] This embodiment uses two connecting components (four-nut U-shaped fixing clamp, 40) as support base points. The connecting component includes a clamp body (52), two wing bolts (16, 21) and corresponding anti-damage discs (22, 23), which can achieve stable clamping at two points.

[0108] A perforated reinforced crossbar (see) Figure 7 It is fixed to the connecting assembly by an extended wing bolt (51) and a double-hole connecting piece (41).

[0109] Multiple sub-beams (including major sub-beams 24, 26, 29, 31 and minor sub-beams 25, 27, 28, 30) are longitudinally (perpendicular to the reinforcing crossbar) detachably fixed to predetermined positions on the reinforcing crossbar via double-hole connecting pieces (41) and extended wing bolts (51). Each sub-beam is equipped with suction cup assemblies at both ends for adsorbing glass or metal frames, thereby transmitting pressure more evenly to the main crossbar.

[0110] Example 3: Wall-mounted

[0111] See Figure 10 and Figure 11 This embodiment can be used when the strength of the door and window frame is insufficient.

[0112] This embodiment uses two flat-plate connecting components as support bases. These components are equipped with expansion screw holes (32, 34) and screw holes (33), allowing them to be directly fixed to the solid walls on both sides of the doors and windows using expansion screws, providing the most stable support. After fixing, the installation method of the reinforcing crossbar and the intermediate connecting mechanism (suction cup assembly or system with sub-beam) is the same as in Embodiment 1 or 2.

[0113] Example 4: Adsorption type with sub-beam (sub-beam is located inside the reinforcing crossbar)

[0114] See Figure 6 , Figure 12 , Figure 13 , Figure 14 and Figure 15 This embodiment is applicable to situations where multiple sliding doors are connected, and demonstrates an implementation using more than two connecting components.

[0115] Five thin connecting components (40) are respectively inserted into and secured to the vertical gaps between the door panels. A perforated reinforcing crossbar (45) is placed and secured to this row of connecting components.

[0116] A long nut (36) is welded to the middle of the sub-beam (42). During installation, the suction cups (38, 39) at both ends of the sub-beam are first attached to the predetermined positions on the glass surface. Then, the extended wing bolts (51) are passed through the corresponding through holes on the reinforcing crossbar (45) and screwed into the long nut (36) of the sub-beam (42). By tightening the nuts on the extended wing bolts (51), a top support connection is formed between the sub-beam and the reinforcing crossbar, thereby connecting the glass and the reinforcement system as one unit.

[0117] Example 5: Top-support type with cushioning layer

[0118] See Figure 16 and Figure 17 This embodiment is an improvement on embodiment 4. It replaces the sub-beam (42) with a suction cup in embodiment 4 with a sub-beam (47) with a buffer pad (43). Except for the contact parts being replaced by the buffer pad, the connection between the sub-beam and the reinforcing crossbar is exactly the same as in embodiment 4. The buffer pad provides a larger flexible contact surface, enhancing the resistance to positive wind pressure.

[0119] Example 6: Top-support type with hinged bolt connection

[0120] See Figure 17 , Figure 18 and Figure 19 This embodiment provides another adjustable angle connection method between the sub-beam and the reinforcing crossbar.

[0121] An elongated hole is made in the sub-beam (47) with a buffer pad layer (48). The ring end of the hinge bolt (44) is inserted into this hole, and then a bolt (46) is inserted from the side of the sub-beam through the ring and locked with a nut to form a hinge. The screw end of the hinge bolt (44) passes through the through hole on the reinforcing crossbar (45) and is fixed with a wing nut (5). This connection method allows the sub-beam to self-adjust within a certain angle, which is suitable for situations where the glass surface is not parallel to the reinforcing crossbar and can effectively avoid local stress concentration in the glass.

[0122] Example 7: Telescopic Reinforced Crossbar

[0123] See Figure 20 To further enhance adaptability, the reinforcing crossbar in this embodiment adopts a two-section telescopic design with a larger tube enclosing a smaller tube. The total length of the crossbar can be adjusted by loosening and tightening the fastening bolts at the joint to accommodate door and window openings of different widths. After adjustment and locking, its function is the same as a one-piece crossbar. When stored, retracting the crossbar greatly saves space.

[0124] Example 8: Multi-bar window reinforcement

[0125] See Figure 21 This embodiment demonstrates the application of the device of the present invention on multiple reinforcing crossbars, suitable for window reinforcement.

[0126] Four connecting components (single-nut U-shaped fixing clips) are used to secure the window frame to a sturdy location. Two reinforcing crossbars (49, 50) are then fixed to their respective connecting components. Finally, suction cup components are installed on each reinforcing crossbar and attached to the glass surface. The principle is similar to that of Example 1, where multiple crossbars work together to improve the overall wind resistance of large windows.

[0127] Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
