Description

Technical Field

[0001] The invention belongs to the field of outdoor sunshade structures, and in particular relates to a high-load-bearing ultra-wide waterproof blade based on a composite material, and application of the blade. Background Art

[0002] Outdoor louver awnings are an ideal shading solution for modern homes and commercial spaces. They can not only effectively block strong direct sunlight and reduce indoor temperatures, but also allow the circulation of natural wind and improve living and working comfort. They are the only choice for those who pursue a high-quality living and working environment.

[0003] At present, the shutter structure of the louver awning is mostly made of aluminum alloy blades, which has excellent corrosion resistance and is particularly suitable for outdoor use. However, the strength of aluminum alloy is insufficient. When the span is too large, it is easy to bend and fall, causing leakage, which restricts the size of the louver awning. At the same time, the bearing capacity of aluminum alloy blades is insufficient, resulting in insufficient snow load capacity of the louver awning, which is not suitable for outdoor use in cold areas. Summary of the invention

[0004] Based on the above-mentioned problems in the prior art, the present invention provides a high-load-bearing and ultra-wide waterproof blade based on composite materials, including a blade body made of aluminum alloy, wherein the blade body is spliced ​​together from several sections, including a load-bearing section and an extension section, and both the load-bearing section and the extension section are provided with an inner cavity, and an anti-bending reinforcement structure is fixedly installed in the inner cavity of the load-bearing section, wherein the anti-bending reinforcement structure extends from one end of the load-bearing section to the other end, and the anti-bending reinforcement structure is made of steel and has a hardness greater than that of the blade body, and the anti-bending reinforcement structure resists the falling and bending of the blade body; the inner cavities of the load-bearing section and the extension section are filled with hard foam glue, and the anti-bending reinforcement structure is fixed by embedding the hard foam glue.

[0007] Among them, a protrusion on the inner cavity wall of the blade body is provided with a snap-in rib that matches the anti-bending reinforcement structure. The snap-in rib and the inner cavity wall cooperate to form an installation slot, and the anti-bending reinforcement structure is snap-installed into the installation slot.

[0008] Among them, the high-load-bearing and ultra-wide waterproof blade based on composite materials also includes a secondary reinforcement structure, and the secondary reinforcement structure includes a third reinforcement part and a fourth reinforcement part that are integrally formed and interconnected with each other. The fourth reinforcement part is vertically arranged up and down when the blade body is in a flipped closed state, and the third reinforcement part and the fourth reinforcement part are vertically arranged or the third reinforcement part is rotated to a vertical state when the blade body is in a flipped open state; a secondary card slot matching the secondary reinforcement structure is arranged on the inner cavity wall of the blade body, and the secondary reinforcement structure is snap-fitted and installed in the secondary card slot; a flip hole for connecting to a flip shaft is also arranged on the blade body, and the louver structure realizes the flipping of the blade body through the flip shaft, and the anti-bending reinforcement structure and the secondary reinforcement structure are both arranged between the main shaft hole and the flip hole and lift the weight of the blade body in this part, that is, the anti-bending reinforcement structure and the secondary reinforcement structure act as counterweights at the same time so that the weight of the side with the anti-bending reinforcement structure and the secondary reinforcement structure is equal to or greater than the other side with the position of the main shaft hole as the center boundary.

[0009] Among them, a hook is provided on one side of the load-bearing section, and a matching hook groove is provided on one side of the extension section; or a groove is provided on one side of the load-bearing section, and a matching hook is provided on one side of the extension section.

[0024] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Embodiment 1:

[0026] As attached Figure 1-6 A high load-bearing ultra-wide waterproof blade based on a composite material is shown, comprising a blade body 1 extruded from an aluminum alloy, wherein the blade body 1 is spliced ​​from two sections, namely a load-bearing section 2 and an extension section 3, wherein the load-bearing section 2 and the extension section 3 are both provided with two inner cavities arranged side by side, two hooks 4 are provided on one side of the load-bearing section 2, and the two hooks 4 are arranged up and down, and two matching hook grooves 5 are provided on one side of the extension section 3, and the load-bearing section 2 and the extension section 3 are spliced ​​into a complete blade body 1 by two sets of mutually matching hooks 4 and hook grooves 5, and the opening of the hook groove 5 of the upper set is The opening is downward, and when the corresponding hook 4 is connected to the hook groove 5, the hook groove 5 extends from the extension section 3 to the load-bearing section 2 and blocks the splicing gap between the two sections. A glue groove 6 is formed between the end of the hook groove 5 and the upper surface of the load-bearing section 2, and sealant is injected into the glue groove 6. A rectangular drainage groove 7 is provided on the upper surface of the extension section 3, and a stepped drainage groove 7 is provided on the upper surface of the load-bearing section 2. The step of the drainage groove 7 gradually decreases in the direction away from the hook 4. The blade body 1 is provided with a glue injection cavity 8 between two groups of mutually matching hooks 4 and hook grooves 5, and sealant is poured into the glue injection cavity 8. The glue injection cavity 8 can be selected whether to inject or inject sealant according to actual needs. When the waterproof requirement is relatively high, both can be injected or injected. When the waterproof requirement is not high, sealant can be selectively injected only into the glue groove 6, or even neither the glue groove 6 nor the glue injection cavity 8 can be injected to reduce the selling price.

[0027] The inner cavity of the load-bearing section 2 is provided with four clip ribs 9 protruding on the inner cavity wall, two of which are arranged in the inner cavity close to the extension section 3 and cooperate with the inner cavity wall to form an installation slot 10, and the other two clip ribs 9 are arranged in another inner cavity of the load-bearing section 2 and cooperate with the inner cavity wall to form a secondary slot 11, and a matching anti-bending reinforcement structure 12 is clipped and installed in the installation slot 10. The anti-bending reinforcement structure 12 is made of steel, and its hardness and structural strength are greater than the blade body 1 made of aluminum alloy; the anti-bending reinforcement structure 12 extends from one end of the load-bearing section 2 to the other end and resists the falling and bending of the blade body 1. The four inner cavities of the blade body 1 are filled with hard foam glue 13, and the hard foam glue 13 is used to fix and embed the anti-bending reinforcement structure 12 and support the inner cavity structure of the blade body 1. The embedding of the hard foam glue 13 can slow down the oxidation corrosion of the anti-bending reinforcement structure 12, and also support the inner cavity of the blade body 1, so that the wall thickness of the blade body 1 can be reduced, and the production cost can be reduced.

[0028] As a preferred embodiment, the anti-bending reinforcement structure 12 includes a first reinforcement part 14 and a second reinforcement part 15 which are integrally formed and interconnected. The second reinforcement part 15 is vertically arranged up and down when the blade body 1 is in a flipped closed state, and the first reinforcement part 14 and the second reinforcement part 15 are vertically arranged. In practical applications, angle steel can be used as the anti-bending reinforcement structure 12. A main shaft hole 16 for connecting to a rotating shaft is arranged on the load-bearing section 2 of the blade body 1, and the blade body 1 is connected to the frame of the louver structure through a rotating shaft; the end of the second reinforcement part 15 away from the first reinforcement part 14 is in a clearance fit with the hole wall of the main shaft hole 16, the other end of the second reinforcement part 15 is in a clearance fit with the vertical wall of the inner cavity, and the end of the first reinforcement part 14 away from the second reinforcement part 15 is in a clearance fit with the horizontal wall of the inner cavity, that is, one end of the anti-bending reinforcement structure 12 abuts against the main shaft hole 16, and the other end abuts against the inner cavity wall. The rotating shaft, the anti-bending reinforcement structure 12 and the blade body 1 form a mutually supporting structure that can be used in To a certain extent, the supporting force is transmitted and the bending force of the falling is dispersed, thereby improving the overall structural strength. The load-bearing section 2 of the blade body 1 is also provided with a flip hole 17 for connecting with the flip shaft. The louver structure realizes the flipping of the blade body 1 through the flip shaft. The mounting slot 10 and the auxiliary slot 11 are both arranged between the main shaft hole 16 and the flip hole 17, so that the anti-bending reinforcement structure 12 is also installed between the main shaft hole 16 and the flip hole 17 and the weight of the blade body 1 in this part is increased, so that the weight of the side where the anti-bending reinforcement structure 12 is arranged is slightly greater than the other side with the main shaft hole 16 as the center. In actual application, the rotating shaft of the louver structure blade is generally arranged in the middle of the blade to achieve the purpose of offsetting the weight on both sides of the rotating shaft, so that the flipping of the blade can be realized more conveniently and easily. However, the louver structure generally sets a water tank under the blade to receive the water flowing from the top of the blade to prevent rainwater from entering the awning. The wider the blade, the larger the space occupied by the blade when it turns and swings downward, that is, the greater the distance between the water tank and the blade, the easier it is for water to float into the awning when the blade flows into the water tank, affecting the user experience. In addition, the louver structure will also require wider side beams to install the blades and the water tank, affecting the appearance of the louver structure, which is also a factor that restricts the width of the blade. Therefore, setting the anti-bending reinforcement structure 12 in the blade body 1 can not only improve the strength of the blade body 1, but also increase the weight of one side of the blade body 1, that is, the other side of the blade body 1 needs a larger weight to offset. In other words, a main shaft hole 16 deviating from the middle of the blade can be set so that the side of the blade that swings upward is larger than the side that swings downward, and then the weight of the two sides is parallel to the anti-bending reinforcement structure 12, so as to achieve the purpose of not occupying too much space under the blade even if the blade is widened, avoiding increasing the distance between the water tank and the blade and the width of the side beam, that is, a wider and larger blade can be made.

[0029] An end cover 18 is provided at each end of the blade body 1, and the ends of the load-bearing section 2 and the extension section 3 are fixedly connected to the end cover 18 at the corresponding end. The setting of the end cover 18 can improve the looseness caused by the gap between the hook 4 and the hook groove 5, so that the splicing of the load-bearing section 2 and the extension section 3 is more stable; a waterproof rubber strip 19 is provided on one side of the blade body 1, and a splicing hook 20 that cooperates with the waterproof rubber strip 19 to compress waterproofing is provided on the other side of the blade body 1. Adjacent blade bodies 1 are connected and waterproofed through the cooperation of the waterproof rubber strip 19 and the splicing hook 20.

[0030] When assembling the blade provided in this embodiment, the anti-bending reinforcement structure 12 is first installed in the installation slot 10, and then the hard foam glue 13 is poured into the inner cavity of the blade body 1. The polymer foam layer formed after the foaming reaction of the foam glue completely fills the inner cavity of the blade body 1. Then the load-bearing section 2 and the extension section 3 are spliced ​​together, and it is selected whether to inject sealant into the glue groove 6 and the glue injection cavity 8 as needed. Finally, the end cover 18 is installed to both ends of the blade body 1 to complete the installation.

[0031] Currently, among the louver awning products on the market, the maximum width of the blades is about 250mm, while the blades provided in this patent can reach more than 300mm.

[0032] The following is a comparison of the natural bending test of conventional blades with different wall thicknesses and the blades provided by this patent. The two ends of the blade are fixed, the middle part falls naturally, and the maximum bending amount is measured. The results are as follows:

[0033]

[0034] In the sample of this patent, the weight of the aluminum alloy is 3.8kg / m, the weight of the steel structure is 1.5kg / m, the weight of the hard foam is 0.2kg / m, and the total weight is 5.5kg / m.

[0035] From the test data in the table above, it can be seen that the blade disclosed in this patent is wider, lighter and has the same or even stronger structural strength than conventional blades. At the same time, after testing, the snow load exceeds 200kg / m 2 The bending and falling amount of the blade is only 20mm. After the load is removed after 10 hours, the blade can return to normal falling and bending amount.

[0036] Embodiment 2:

[0037] The difference between this embodiment and the first embodiment is that a secondary reinforcement structure 21 is installed in the load-bearing section 2. Figure 7As shown, the secondary reinforcement structure 21 includes a third reinforcement part 22 and a fourth reinforcement part 23 that are integrally formed and connected to each other. The fourth reinforcement part 23 is vertically arranged up and down when the blade body 1 is in the flipped closed state. The third reinforcement part 22 and the fourth reinforcement part 23 are arranged vertically. The secondary reinforcement structure 21 is snap-fitted and installed in the secondary slot 11. In practical applications, angle steel can also be used as the secondary reinforcement structure 21. In this embodiment, the anti-bending reinforcement structure 12 and the secondary reinforcement structure 21 are both arranged between the main shaft hole 16 and the flip hole 17 and increase the weight of the blade body 1 in this part, so that the weight of one side where the anti-bending reinforcement structure 12 and the secondary reinforcement structure 21 are arranged is equal to the weight of the other side with the main shaft hole 16 as the middle boundary. Similarly, the secondary reinforcement structure 21 can not only increase the strength of the blade, but also act as a counterweight. In practice, the secondary reinforcement structure 21 plays a more counterweight role, that is, the secondary reinforcement structure 21 does not need to completely penetrate the entire blade body 1, and the corresponding length can be set as needed to achieve the purpose of parallel weight.

[0038] The above-mentioned embodiments only express two implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
