Description

Technical Field

[0001] The utility model relates to a rolling shutter door, in particular to a device for strengthening the wind pressure resistance of the exterior wall rolling shutter door. Background Art

[0002] Rolling shutter doors can be set with large door openings, which can fully meet the needs of users to move in equipment and goods. They are often used in various buildings. Due to the large area of ​​rolling shutter doors, in strong wind pressure areas such as coastal and mountainous areas, the rolling shutter doors themselves are not strong enough to resist wind pressure, which often causes varying degrees of damage to the rolling shutter doors.

[0003] Rolling shutter doors are constructed with multiple articulated panels connected in series. They rotate upward and downward within a fixed slideway, pivoting around a reel above the door. Similar to a wall, a rolling shutter door serves as a horizontal partition. It consists of 13 components: a curtain panel, base plate, guide rails, supports, reel, housing, control box, roller, stopper, lintel, manual quick-release switch, pushbutton switch, and safety device. They are typically mounted on a stable structural system on either side of the door opening. Rolling shutter doors are suitable for buildings across various industries, especially those with larger openings, which can fully accommodate the movement of equipment and materials of various sizes. In coastal, mountainous, or plateau regions, buildings in these areas often face specific requirements for wind resistance due to the geographical environment. For rolling shutter doors with openings wider than 4 meters, traditional approaches to improve the curtain panel structure or thicken the material to enhance the product's inherent strength, or simply adding vertical reinforcement systems on the inside and outside, fail to effectively improve the door's overall wind resistance.

[0004] Therefore, the known rolling door structure has the above-mentioned inconveniences and problems. Utility Model Content

[0025] Figure 1 This is a schematic structural diagram of an embodiment of the present utility model;

[0026] Figure 2 This is a schematic diagram of a grid-type wind pressure resistance device according to an embodiment of the present invention. DETAILED DESCRIPTION

[0027] The present invention will be further described below with reference to the embodiments and the accompanying drawings.

[0028] Example 1

[0029] Please refer to Figure 1 and Figure 2 This enhanced wind pressure-resistant device for exterior wall rolling shutter doors takes into account local wind loads, calculates the strength of the shutter blades to determine the effective wind pressure-resistant area of ​​the shutter itself, divides the load-bearing area of ​​the rolling shutter door, and arranges keels at the divisions. Based on the length and width of the divisions, the strength of the profile is calculated to determine the cross-section of the keel profile. This effectively utilizes the rolling shutter door's additional wind-resistant system to protect the shutter blades from typhoon damage. An I-beam (galvanized 10# channel steel) runner 7 is installed and secured to the doorposts on both sides, close to the top of the rolling shutter door. A pulley block 8 (1t model) is installed on the I-beam runner. A latch 9 (350 type) is secured to the windproof upright 5 using self-tapping screws or welding. The windproof upright 5, with the latch installed, is secured to the pulley block 8. The windproof upright fixing supports 3 and 4 are then secured to the doorposts using expansion bolts or welding. (The supports are made of 5mm thick steel plate with a groove formed in the groove, which is 5mm wider than the width of the windproof crossbar 6 to facilitate crossbar installation and removal.) Install the lifting lugs (2) (made of φ12mm round steel) at each end of the windproof crossbar (6) and place it on the brackets on either side of the doorpost. To facilitate installation and removal of the windproof crossbar during operation, install mini hand chain hoists (1) on top of each side of the door (with a fall chain length 1.2 times the door's clear height). During construction, first install the windproof vertical poles, then the windproof crossbars, ensuring that the vertical poles are inside the crossbars. For ease of installation and removal, high-strength aluminum alloy square tubes can be used for both the vertical and crossbars. The specifications are confirmed by strength calculations based on the wind loads the profiles can withstand. Follow these steps to install the windproof vertical poles and crossbars on both the inside and outside of the door.

[0030] Example 2

[0031] Manufacturing method of the utility model for enhancing the wind pressure resistance device of the exterior wall rolling shutter door:

[0032] 1. Divide the force-bearing area of ​​the rolling shutter door.

[0033] 2. Fix the I-beam slideway 7 (galvanized 10# channel steel) close to the upper opening of the rolling door and fix it to the doorposts on both sides by expansion bolts or welding.

[0034] 3. Install the pulley block 8 (model 1t) on the I-beam slideway.

[0035] 4. Fix the pin 9 (type 350) to the wind-resistant pole 5 using self-tapping screws or welding.

[0036] 5. Fix the wind-resistant vertical pole with the installed pins on the pulley assembly through the pins.

[0037] 6. Install the wind-resistant vertical pole fixing supports 3 and 4 and fix them to the doorposts through expansion bolts or welding (the fixing parts are made of 5mm thick steel plates into grooves, the width of the grooves is 5mm larger than the width of the wind-resistant crossbars, which is convenient for the installation and removal of the crossbars).

[0038] 7. Install the hanging ears 2 (made of φ12mm round steel) at both ends of the wind-resistant crossbar 6 and place it on the brackets on both sides of the doorpost.

[0039] 8. Considering that the horizontal bar of the wind-resistant device is easy to install and remove during the use of the rolling door, mini hand hoists are installed on the top of both sides of the rolling door (the length of the fall chain is 1.2 times the net height of the rolling door).

[0040] During construction, first install the wind-resistant vertical poles, then the wind-resistant horizontal poles, ensuring that the vertical poles are inside the horizontal poles. For ease of installation and removal, high-strength aluminum alloy square tubes can be used for both wind-resistant vertical poles and horizontal poles, with specifications confirmed by force calculations. Both the inside and outside of the rolling shutter door require installation of the wind-resistant vertical poles and horizontal poles according to the above construction steps.

[0041] The above embodiments are intended only to illustrate the present invention and are not intended to limit the present invention. Persons skilled in the art may make various modifications or variations without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions are intended to fall within the scope of the present invention and are defined by the claims.
