Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy technology, and in particular to a double-layer rod connection structure of aluminum alloy. Background Technology

[0002] Aluminum alloy structures have advantages such as high durability, lightweight and high strength, integration, industrialization, full assembly, exquisite appearance and high degree of completion. Aluminum grid shell structures are gradually replacing steel grid shell structures and have become the main structural form.

[0003] The existing cross-sectional dimensions of aluminum alloy components for buildings are insufficient to meet the needs of increasingly complex large-span reticulated shell structures. The structural members lack strength and stiffness, and it is not easy to adjust the cross-sectional height of aluminum alloy components, which reduces the stability of aluminum alloy members during use. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model proposes a double-layer aluminum alloy rod connection structure. The double-layer aluminum alloy rods are connected by ring groove rivets or welding, which can effectively solve the problems of insufficient strength and rigidity of aluminum alloy components. The double-layer rod structure can overcome the limitations of extrusion equipment on component size, increase the cross-sectional height of aluminum alloy components, and also take into account the aesthetics of the building.

[0005] The technical solution to achieve the purpose of this utility model is: an aluminum alloy double-layer rod connection structure, comprising:

[0006] Upper rod;

[0007] A lower rod is located below the upper rod, and the lower rod is connected to the upper rod by annular groove rivets or welding, and both the lower rod and the upper rod are aluminum alloy rods.

[0008] In some embodiments, the top of the lower rod is provided with a flange lug corresponding to the bottom of the upper rod, and the flange lug is connected to the bottom of the upper rod by a ring groove rivet.

[0009] In some embodiments, the top of the lower rod and the bottom of the upper rod are connected by a connecting plate, the connecting plate being connected to the top of the lower rod by a grooved rivet, and the connecting plate being connected to the bottom of the upper rod by another grooved rivet.

[0010] In some embodiments, the top of the lower rod is provided with a U-shaped slot, and the bottom of the upper rod is inserted into the U-shaped slot, thereby connecting the upper rod and the U-shaped slot by annular groove rivets or welding.

[0011] In some embodiments, when the upper rod and the U-shaped slot are connected by welding, the thickness of the U-shaped slot is greater than the thickness of the lower rod, and the thickness of the portion of the upper rod inserted into the U-shaped slot is greater than the thickness of the remaining portion of the upper rod. The welded portions of the upper rod and the U-shaped slot are thickened to account for the impact of welding on the strength of the aluminum alloy. This thickening process improves the structural strength of the aluminum alloy rod; the specific thickening value and locations can be determined according to the design.

[0012] In some embodiments, the top of the lower member and the bottom of the upper member are connected by a connecting plate. The connecting plate is welded to corresponding portions of the upper and lower members, and the thickness of the portion of the lower member corresponding to the connecting plate is greater than the thickness of the rest of the lower member, and the thickness of the portion of the upper member corresponding to the connecting plate is greater than the thickness of the rest of the upper member. The welded portions of the upper and lower members are thickened to account for the impact of welding on the strength of the aluminum alloy. Thickening improves the structural strength of the aluminum alloy member; the specific thickening value and location can be determined according to the design.

[0013] In some embodiments, the grooved rivet is a countersunk grooved rivet or a single-sided grooved rivet.

[0014] In some embodiments, the upper rod and the lower rod are provided with corresponding buckles.

[0015] In some embodiments, the cross-sectional shape of the upper and lower members is not limited to T-shaped, Π-shaped, I-shaped or ☐-shaped, and the connecting plate can be provided on one side or both sides.

[0016] In some embodiments, local thickening is required during welding to account for the reduction in strength and stiffness of the aluminum alloy caused by welding. The number of annular groove rivets is determined according to the principle of equal strength.

[0017] In some embodiments, the upper rod and the lower rod are respectively provided with a connecting post and a fixing post. The connecting post is connected to the inner tube, and the fixing post is connected to the outer tube. A portion of the inner tube is inserted into the outer tube, and the length of the portion of the inner tube inserted into the outer tube is adjustable. After adjustment, the inner tube and the outer tube can be connected in a limited position.

[0018] In some embodiments, multiple connecting columns and fixing columns are provided, spaced apart along the upper and lower members.

[0019] Compared with existing technologies, the significant advantages of this invention are:

[0020] This utility model's aluminum alloy double-layer rod connection structure breaks through the limitations of extrusion equipment on component size, proposing a double-layer composite component that effectively solves the problem of insufficient strength and stiffness in aluminum alloy structures.

[0021] The double-layer aluminum alloy structure uses grooved rivets or welding to connect the upper and lower members, ensuring the transmission of force and the overall synergistic effect of the components.

[0022] The upper and lower members are equipped with corresponding buckles, which can be used to connect decorative panels to cover the sides and ensure the aesthetics of the building.

[0023] This utility model uses connecting plates on both sides of the upper and lower rods, which are fixed by ring groove rivets or welding. Then, a connecting post is installed in the upper rod and a fixing post is installed in the lower rod. Pressing the limiting post moves the sliding block, and the telescopic spring retracts. Then, the inner tube is sleeved on the outer tube. Releasing the limiting post allows the telescopic spring to return to its elasticity, so that the limiting post is located in the limiting hole. Repeated operation can adjust the distance between the outer tube and the inner tube, thereby supporting the upper and lower rods, improving the strength of the upper and lower rods after fixation, and improving the efficiency of use.

[0024] This invention solves the problem that the cross-sectional dimensions of existing aluminum alloy components for buildings are insufficient to meet the needs of increasingly complex large-span reticulated shell structures, the structural members have insufficient strength and stiffness, and the cross-sectional height of aluminum alloy components is not easy to adjust, thus reducing the stability of aluminum alloy components during use.

[0037] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0038] This utility model provides an improved aluminum alloy double-layer rod connection structure. The technical solution of this utility model is as follows:

[0039] Example 1:

[0040] like Figure 1 As shown, the aluminum alloy double-layer rod connection structure of this utility model includes an upper rod 1 and a lower rod 2, wherein the lower rod 2 is located below the upper rod 1, or, in embodiment one, the upper rod 1 is placed on the lower rod 2. The upper rod 1 and the lower rod 2 are connected by a ring groove rivet 3. Both the upper rod 1 and the lower rod 2 are aluminum alloy rods, and the aluminum alloy rods are integrally extruded aluminum alloy.

[0041] Furthermore, the cross-section of the upper member 1 is π-shaped, and the cross-section of the lower member 2 is I-shaped.

[0042] Furthermore, the top of the lower rod 2 is provided with a flange lug corresponding to the bottom of the upper rod 1, and the flange lug is connected to the bottom of the upper rod 1 by a ring groove rivet 3.

[0043] Furthermore, corresponding buckles 4 are provided on the upper rod member 1 and the lower rod member 2. The buckle 4 provided on the lower rod member 2 is provided at the edge of the top flange of the lower rod member 2, and the buckle 4 provided on the upper rod member 1 is provided at the edge of the top flange of the upper rod member 1. The buckle 4 is provided on the lower surface of the top flange of the upper rod member 1. A decorative plate can be installed at the corresponding buckle 4 on the corresponding side, and the side portion of the upper rod member 1 can be covered by the decorative plate to meet the architectural aesthetics. Preferably, the buckle 4 is in an "L" shape; through the "L" shape setting, the installation of the decorative plate is facilitated.

[0044] Furthermore, the ring groove rivet 3 is a countersunk head ring groove rivet or a single-sided ring groove rivet, and a single-sided ring groove rivet is used in the closed cross-section. The ring groove rivet 3 can be made of stainless steel or other materials. The number of the ring groove rivets 3 can be determined according to the equal strength principle.

[0045] Embodiment 2, as Figure 2 shown, the top of the lower rod member 2 and the bottom of the upper rod member 1 are connected by a connecting plate 5. The connecting plate 5 and the top of the lower rod member 2 are connected by a ring groove rivet 3, and the connecting plate 5 and the bottom of the upper rod member 1 are connected by another ring groove rivet 3.

[0046] Furthermore, the cross-sections of the upper rod member 2 and the lower rod member 1 are both T-shaped.

[0047] Still further, the connecting plate 5 is provided on both sides of the upper rod member 2 and the lower rod member 1. The connecting plate 5 is an aluminum alloy plate or a stainless steel plate.

[0048] Embodiment 3, as Figure 3 shown, the top of the lower rod member 2 is provided with a U-shaped slot 6, and the bottom of the upper rod member 1 is inserted into the U-shaped slot 6. Furthermore, the upper rod member 1 and the U-shaped slot 6 are connected by a ring groove rivet 3.

[0049] Furthermore, the cross-sections of the upper rod member 2 and the lower rod member 1 are both T-shaped.

[0050] Embodiment 4, as Figure 4 shown, the cross-section of the upper rod member 1 is in a dry shape, and the cross-section of the lower rod member 2 is T-shaped. The top of the lower rod member 2 and the bottom of the upper rod member 1 are connected by two connecting plates 5. The connecting plate 5 and the top of the lower rod member 2 are connected by a ring groove rivet 3, and the connecting plate 5 and the bottom of the upper rod member 1 are connected by another ring groove rivet 3.

[0051] Embodiment 5, as Figure 5 shown, the top of the lower rod member 2 is provided with a U-shaped slot 6, and the bottom of the upper rod member 1 is inserted into the U-shaped slot 6. Furthermore, the upper rod member 1 and the U-shaped slot 6 are connected by welding.

[0052] Furthermore, during welding, the thickness of the U-shaped slot 6 is greater than the thickness of the lower member 2, and the thickness of the portion of the upper member 1 inserted into the U-shaped slot 6 is greater than the thickness of the remaining portion of the upper member 1. Specifically, during welding, local thickening is required to account for the reduction in strength and stiffness of the aluminum alloy member caused by welding. Thickening can improve the structural strength of the aluminum alloy member; the specific thickening value and location can be determined according to the design.

[0053] Furthermore, the cross-sections of both the upper member 2 and the lower member 1 are T-shaped.

[0054] Example 6, as Figure 6 As shown, the top of the lower member 2 and the bottom of the upper member 1 are connected by a connecting plate 5. This connecting plate is welded to the corresponding portions of the upper member 1 and the lower member 2. The thickness of the portion of the lower member 2 corresponding to the connecting plate 5 is greater than the thickness of the rest of the lower member 2, and the thickness of the portion of the upper member 1 corresponding to the connecting plate 5 is greater than the thickness of the rest of the upper member 1. Specifically, during welding, local thickening is required to account for the reduction in strength and stiffness of the aluminum alloy member caused by welding. Thickening can improve the structural strength of the aluminum alloy member. The specific thickening value and the thickening location can be determined according to the design.

[0055] The cross-sectional shape of the first and second rods of this utility model is not limited to T-shaped, π-shaped, I-shaped or ☐-shaped, but can also be other shapes.

[0056] When setting up the connecting plate, it can be set on one side or both sides.

[0057] This utility model proposes an aluminum alloy double-layer rod connection structure, transforming single-layer components into double-layer components. This overcomes the height limitations imposed by extrusion equipment, effectively solving problems such as insufficient strength and stiffness in aluminum structural components, while also ensuring the overall synergistic effect of the components. This connection structure offers advantages such as simple construction, energy efficiency, environmental friendliness, good permeability, corrosion resistance, aesthetic appeal, and maintenance-free operation. It meets the requirements of green materials, green construction, and green building.

[0058] Example 7:

[0059] like Figure 7 and Figure 9As shown in Embodiment 7, the upper rod 1 and the lower rod 2 are respectively provided with a connecting post 10 and a fixing post 11, which are arranged opposite to each other. An inner tube 7 is connected to the connecting post 10, and an outer tube 8 adapted to the inner tube 7 is connected to the fixing post 11. When the upper rod 1 and the lower rod 2 are connected, a portion of the inner tube 7 extends into the outer tube 8, and the length of the portion of the inner tube 7 extending into the outer tube 8 is adjustable so that the length of the inner tube 7 and the outer tube 8 after connection can be adapted to the distance between the corresponding flanges of the upper rod 1 and the lower rod 2. After the inner tube 7 is adjusted to the correct position, the inner tube 7 and the outer tube 8 can be connected in a limited manner.

[0060] Furthermore, combined Figure 8 As shown, multiple connecting columns 10 and fixing columns 11 are provided, which are spaced along the flange plates of the upper rod 1 and the lower rod 2. The connecting columns 10 and fixing columns 11 are also provided on both sides of the flange plates of the upper rod 1 and the lower rod 2. The connection strength between the upper rod 1 and the lower rod 2 is improved by the spaced inner tube 7 and outer tube 8.

[0061] Furthermore, the inner tube 7 and the outer tube 8 can be fitted onto the corresponding connecting post 10 and fixing post 11. The inner tube 7 and the outer tube 8 can also be connected to the corresponding connecting post 10 and fixing post 11 by bolts or welding.

[0062] Furthermore, corresponding parts of the inner tube 7 and the outer tube 8 are provided with connecting holes. After adjusting the length of the inner tube 7 inserted into the outer tube 8, connecting bolts can be inserted into the corresponding connecting holes to achieve the limiting connection between the inner tube 7 and the outer tube 8, thus restricting the position adjustment function of the inner tube 7.

[0063] In another preferred embodiment, multiple limiting holes 9 can be formed on the outer tube 8, and a movable groove can be formed near the end of the inner tube 7. A sliding block 12 and a limiting post 13 are slidably connected in the movable groove. A telescopic spring 14 is connected between the limiting post 13 and the sliding block 12. The telescopic spring 14 can push the sliding block 12 and the limiting post 13 out of the corresponding movable groove. By pressing the sliding block 12 and the limiting post 13, the telescopic spring 14 can be compressed, allowing the sliding block 12 and the limiting post 13 to retract into the inner tube 7. Thus, when the inner tube 7 is inserted into the outer tube 8, the sliding block 12 and the limiting post 13 can be pushed inward. When the end of the inner tube 7 moves downward to the position of the corresponding limiting hole 9 on the outer tube 8, the telescopic spring 14 can cause the sliding block 12 and the limiting post 13 to extend out of the corresponding limiting hole 9, thereby limiting the inner tube 7 and the outer tube 8. If further adjustment of the position of the inner tube 7 is needed, the sliding block 12 and the limiting post 13 can be pushed inward to retract them, and then the position of the inner tube 7 can be adjusted.

[0064] The specific working method is as follows: During use, the connecting plates 5 on both sides of the upper rod 1 and the lower rod 2 are fixed by welding. Then, the inner tube 7 is inserted into the outer tube 8, and the overall length of the inner tube 7 and the outer tube 8 is less than the distance between the corresponding flange plates of the upper rod 1 and the lower rod 2. Then, the outer tube 8 is clamped onto the fixing post 11, and the outer tube 8 is connected to the fixing post 11 by bolts or welding. Then, the inner tube 7 is moved upward to adjust it, and the inner tube 7 is clamped onto the connecting post 10. When moving and adjusting the inner tube 7, the limit between the inner tube 7 and the outer tube 8 can be contacted first. After adjusting the position of the inner tube 7, the inner tube 7 and the outer tube 8 are limited (this can be done with bolts, or with a mechanism consisting of a pressable sliding block, a limit post, and a telescopic spring). Then, the inner tube 7 is connected to the connecting post 10. This realizes the use of the outer tube 8 and the inner tube 7 to support the upper rod 1 and the lower rod 2, improves the strength of the upper rod 1 and the lower rod 2 after fixation, and improves the efficiency of use.

Matters not covered in this utility model are common knowledge to those skilled in the art.
