Description

Technical Field

[0001] The invention relates to the technical field of building structures, and in particular to a light aluminum-wood composite beam. Background Art

[0002] As an innovative structural form in the field of modern architecture, the background technology of aluminum-wood composite beams combines the excellent performance of aluminum alloy materials with the natural advantages of wood. With the growing demand for lightweight, durable, environmentally friendly and convenient construction in the construction industry, traditional single-material beams can no longer meet all requirements. Therefore, aluminum-wood composite beams came into being and became a structural solution with multiple advantages.

[0003] In the patent named as light steel-wood composite beam, the patent with the authorization number of CN114016665B proposes to combine the high strength and good plasticity of steel to make the building more solid and durable. However, the existing steel-wood composite structural components are single in form, mostly in the form of hot-rolled steel and wood separate combination, and the components are heavy in mass, high in production cost, cumbersome in assembly, and cannot be disassembled and replaced, which is difficult to meet the modern development trend of economical and practical with large bearing capacity. By combining C-shaped steel with multi-layer bakelite, the overall seismic performance is enhanced and the overall weight and cost of the composite beam components are reduced. However, during use, the overall mass of the C-shaped steel is heavy, and the two C-shaped steels need to be welded before being connected to each other. After welding, it is not easy to separate and replace the structural components. At the same time, during the welding process, the two C-shaped steels need to be tightly compacted in real time to reduce the gap therein. Once cracks appear at the welding point, the cracks will extend during long-term use, which is more likely to cause separation. For this reason, a light aluminum-wood composite beam is proposed. Summary of the invention

[0004] The object of the present invention is to provide a light aluminum-wood composite beam to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a lightweight aluminum-wood composite beam, comprising two C-shaped aluminum side beams, wherein the two C-shaped aluminum side beams are integrally formed with two snap-fitting edges on opposite sides, and the two snap-fitting edges are fixedly connected to a plurality of snap-fitting protrusions on a side away from the C-shaped aluminum side beam, wherein the snap-fitting protrusions are in an isosceles trapezoid, and the upper bottom edge of the snap-fitting protrusions is fixedly connected to a side of the snap-fitting edge away from the C-shaped aluminum side beam, and the lower bottom edge of the snap-fitting protrusions faces the other C-shaped aluminum side beam, and the plurality of snap-fitting protrusions on the outer sides of the two C-shaped aluminum side beams are staggered, and the two C-shaped aluminum side beams are snap-fitted to each other through the plurality of snap-fitting protrusions, and a built-in hollow chamber is formed between the two C-shaped aluminum side beams, and a hollow filling aluminum frame is installed inside the built-in hollow chamber, and gap filling structures are connected to both sides of the snap-fitting protrusions.

[0006] Preferably, the gap filling structure includes a plurality of compressed wood chip boards, the isosceles outer walls on both sides of the snap-in protrusions are provided with limiting grooves, the compressed wood chip boards are snap-fitted to the inner walls of the limiting grooves, a grouting pipe is installed inside the limiting grooves, the grouting pipe is located between the compressed wood chip board and the limiting grooves, a plurality of water outlet holes are opened outside the grouting pipe, a soft liquid infusion pipe is connected to the grouting pipe, a one-way valve sheet is installed at the inlet of the grouting pipe, the soft liquid infusion pipe is used to inject water into the interior of the grouting pipe and inject water into the compressed wood chip board through the plurality of water outlet holes outside the grouting pipe, and after the water is injected into the interior of the compressed wood chip board, the compressed wood chip board will expand to fill the gaps where the plurality of snap-in protrusions are snapped into each other.

[0007] Preferably, a wear-resistant rubber snap-in bag is integrally formed on the outside of the grouting pipe, and the wear-resistant rubber snap-in bag is in the shape of an inverted triangle. The sharp corners of the wear-resistant rubber snap-in bags on the isosceles sides on both sides of the snap-in protrusion are in opposite directions, and a plurality of water outlets are connected with part of the wear-resistant rubber snap-in bags. The wear-resistant rubber snap-in bag is used to inject adhesive into the limiting groove through the grouting pipe, so that a part of the wear-resistant rubber snap-in bag is expanded by the adhesive and snapped with the wear-resistant rubber snap-in bags with opposite sharp corners. After a part of the wear-resistant rubber snap-in bag is expanded, it will be inserted into the compressed wood chip board that has already expanded and separated, forming an extruded filling inside the compressed wood chip board.

[0008] Preferably, another part of the wear-resistant rubber snap-in bag is fixedly connected to a sealing elastic membrane on one side close to the inner side wall of the limiting groove, and a closed cavity is formed between the sealing elastic membrane and the other part of the wear-resistant rubber snap-in bag. The closed cavity is filled with a non-Newtonian liquid. The non-Newtonian liquid is used to harden during vibration, thereby forming a hardened connection between the wear-resistant rubber snap-in bags that are snap-fitted to each other at the sharp corners, thereby improving the connection stability.

[0009] Preferably, a portion of the non-Newtonian liquid is filled with magnetic powder, and another portion of the non-Newtonian liquid is filled with iron powder. The filling of the magnetic powder and the iron powder causes the adjacent and snap-fitted wear-resistant rubber snap-fit ​​bags to approach and attract each other due to the magnetic attraction between the magnetic powder and the iron powder.

After the secondary welding, the welding points are welded along the gaps between the plurality of snap-fit ​​protrusions, and crack extension will not occur.

[0017] In the present invention, after the two C-shaped aluminum side beams are mutually clamped by a plurality of clamping protrusions, water is injected into the interior of the grouting pipe. After the water is injected into the interior of the grouting pipe, the water is evenly transported to the compressed wood chip board through the external water outlet. After the water enters the compressed wood chip board, the water causes the compressed wood chip board in the original compressed state to expand and diverge to the original state. When the compressed wood chip board expands and diverges to the original state, the compressed wood chip board in the original state gradually fills the gap between the two clamping protrusions, thereby filling the gap between the two C-shaped aluminum side beams, reducing the shaking space during vibration, and reducing the phenomenon of unstable connection.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Embodiment 1: Figure 1 As shown, the present application provides a lightweight aluminum-wood composite beam, comprising two C-shaped aluminum side beams 100, wherein the two C-shaped aluminum side beams 100 have two integrally formed snap-fitting edges 101 on opposite sides thereof, and the two snap-fitting edges 101 are fixedly connected to a plurality of snap-fitting protrusions 102 on a side away from the C-shaped aluminum side beam 100, wherein the snap-fitting protrusions 102 are isosceles trapezoidal, and the upper bottom edge of the snap-fitting protrusions 102 is fixedly connected to a side of the snap-fitting edge 101 away from the C-shaped aluminum side beam 100, and the lower bottom edge of the snap-fitting protrusions 102 faces the other C-shaped aluminum side beam 100, and the plurality of snap-fitting protrusions 102 on the outer sides of the two C-shaped aluminum side beams 100 are staggered, and the two C-shaped aluminum side beams 100 are snap-fitted to each other via the plurality of snap-fitting protrusions 102, and both sides of the snap-fitting protrusions 102 are connected to a gap filling structure.

[0030] Specifically, during use, the staff can assemble the two C-shaped aluminum side beams 100 through the snap-fitting protrusions 102 during the assembly process. During the assembly process, the snap-fitting protrusions 102 between the two C-shaped aluminum side beams 100 can achieve multiple continuous snap-fits through dislocation. After achieving multiple continuous snap-fits, even if two connected C-shaped aluminum side beams 100 are used without welding, good stability can be achieved. At the same time, after using the snap-fitting protrusions 102 to achieve the connection between the two C-shaped aluminum side beams 100, welding can be performed using multiple snap-fitting protrusions 102 as contact points to further increase the connection stability between the two C-shaped aluminum side beams 100. After welding, even if cracks appear at the welding points, because the welding is at the snap-fitting connection between the snap-fitting protrusions 102, continuous pulling of the cracks will not cause continuous breakage, thereby reducing the occurrence of continuous cracks.

[0031] Furthermore, the shape of the snap-fitting protrusion 102 is an isosceles trapezoid, and the snap-fitting between two adjacent C-shaped aluminum side beams 100 is achieved by a plurality of isosceles trapezoidal snap-fitting protrusions 102, one of the isosceles trapezoids will be snapped into the gap between the two snap-fitting protrusions 102 of the other C-shaped aluminum side beam 100, thereby forming a concave-convex snap-fitting, thereby enhancing the overall connection stability.

[0032] like Figure 1-Figure 3 As shown, a built-in hollow chamber is formed between the two C-shaped aluminum side beams 100, and a hollow filling aluminum frame 104 is installed inside the built-in hollow chamber. The hollow filling aluminum frame 104 is a square support frame composed of four triangular hollow aluminum support frames, and the four triangular hollow aluminum support frames are fixedly connected by multiple first connecting bolts 103.

[0033] Specifically, during use, after the two C-shaped aluminum side beams 100 are clamped together by a plurality of clamping protrusions 102, a hollow filling aluminum frame 104 will be installed in the middle position of the two C-shaped aluminum side beams 100. The hollow filling aluminum frame 104 is used as the middle support beam of the two C-shaped aluminum side beams 100, and the hollow filling aluminum frame 104 is a square support frame formed by four triangular hollow aluminum support frames. The four triangular hollow aluminum support frames are combined to improve the overall support stability. The stability of the triangle is utilized and the corners of the four triangles are arranged relatively to each other, so that an "X"-shaped support skeleton is formed in the middle position of the square support frame, which enhances the stability while increasing the overall support strength.

[0034] Furthermore, the hollow inner cavity of the triangular hollow aluminum support frame is filled with lightweight concrete. By filling the lightweight concrete, the internal space of the hollow filled aluminum frame 104 is filled again to increase its overall stability and strength, and multiple hollow filled aluminum frames 104 are threadedly connected by multiple first connecting bolts 103 to increase their connectivity. The reason for not designing it as an integrated square with an "X"-shaped support column in the middle is that the multiple triangles have a certain degree of stable support during the mutual extrusion process, and the side walls of the multiple triangular hollow aluminum support frames will have stronger support during the stabilization process than the single-layer side walls.

[0035] like Figure 1 As shown, upper and lower spacing filling layers are formed between the hollow filling aluminum frame 104 and the two C-shaped aluminum side beams 100 , and a plurality of wood composite boards 105 are filled between the upper and lower spacing filling layers.

[0036] Specifically, during use, if aluminum alloy is used alone as a crossbeam, the consumption is relatively large. During use, multiple wooden composite panels 105 can be filled between the C-shaped aluminum side beams 100 and the hollow filling aluminum frame 104 to fully utilize the energy-saving and environmental protection advantages of the wooden structure, and combined with the strength and good plasticity of the aluminum profile, the building is made more sturdy and durable.

[0037] Furthermore, a plurality of connecting threaded rods 800 are connected through the two C-shaped aluminum side beams 100, and the connecting threaded rods 800 are threadedly connected to the plurality of wooden composite boards 105. The plurality of wooden composite boards 105 and the two C-shaped aluminum side beams 100 are connected by the connecting threaded rods 800, and nuts are used to tighten the two ends of the connecting threaded rods 800, so that the plurality of wooden composite boards 105 are fully abutted against the inner wall of the C-shaped aluminum side beam 100 when cooperating with the connecting threaded rods 800.

[0038] like Figure 1 As shown, two triangular hollow aluminum support frames close to the inner wall of the C-shaped aluminum side beam 100 are fixedly connected to the C-shaped aluminum side beam 100 by a plurality of second connecting bolts 700 .

[0039] Specifically, the side of the hollow filling aluminum frame 104 close to the wooden composite board 105 is limited by the C-shaped aluminum side beam 100 and the multiple wooden composite boards 105, and the hollow filling aluminum frame 104 away from the wooden composite board 105 is fixed and limited between the C-shaped aluminum side beam 100 through multiple second connecting bolts 700, and the hollow filling aluminum frame 104 composed of multiple triangular hollow aluminum support frames is fixed for the second time as a whole.

[0040] The technical solution in the above-mentioned embodiment of the present application has at least the following technical effects or advantages: relative to the prior art, in the present embodiment, in the process of connecting the two C-shaped aluminum side beams 100, a plurality of snap-in protrusions 102 are interconnected to form a snap-in connection, and secondary welding can be performed after the connection. After the secondary welding, the welding points are welded along the gaps between the plurality of snap-in protrusions 102, and crack extension will not occur. Even if cracks occur at the welding points, the connection stability between the two C-shaped aluminum side beams 100 can still be maintained, thereby increasing the overall strength and ease of assembly.

[0041] Embodiment 2: Considering that in actual use, during the welding process, although the snap connections between the multiple snap-in protrusions 102 can be welded from above, there will still be gaps at the side walls where the multiple snap-in protrusions 102 are snapped. The existence of the gap may provide shaking space when the beam body is vibrated. The existence of the shaking space will increase the vibration amplitude, resulting in the phenomenon of connection stability. In view of the above technical problems, the present application proposes a gap filling structure to solve the above technical problems, specifically:

[0042] like Figure 4-Figure 5 As shown, the gap filling structure includes a plurality of compressed wood chip boards 201, and the isosceles outer walls on both sides of the clamping protrusion 102 are provided with limiting grooves 200. The compressed wood chip boards 201 are clamped on the inner walls of the limiting grooves 200. A grouting pipe 202 is installed inside the limiting grooves 200. The grouting pipe 202 is located between the compressed wood chip boards 201 and the limiting grooves 200. A plurality of water outlet holes 203 are provided outside the grouting pipe 202. The grouting pipe 202 is connected to a soft A one-way valve sheet 600 is installed at the inlet of the infusion pipe and the grouting pipe 202. The soft infusion pipe is used to inject water into the interior of the grouting pipe 202 and inject water into the compressed wood chip board 201 through multiple water outlet holes 203 outside the grouting pipe 202. After the water is injected into the compressed wood chip board 201, the compressed wood chip board 201 will expand, and the expanded compressed wood chip board 201 will fill the gaps between the multiple clamping protrusions 102 that are clamped together.

[0043] Specifically, after the two C-shaped aluminum side beams 100 are connected by using multiple snap-in protrusions 102, the staff can also use the soft infusion tube connected to the filling machine. After connecting the filling machine to the soft infusion tube, the user can deliver water into the grouting tube 202. When the water enters the interior of the grouting tube 202, the interior of the grouting tube 202 will be filled with water and the water in the grouting tube 202 will be injected into the compressed wood chip board 201 located in the limiting groove 200 through multiple water outlets 203 opened on the outside of the grouting tube 202. When the compressed wood chip board 201 contacts the water, it will expand as a whole, and the compressed volume will expand to the original uncompressed state. When the compressed wood chip board 201 between adjacent snap-in protrusions 102 is fully expanded, it will fully fill the snap-in gap between the snap-in protrusions 102, further increasing the connection stability between the two C-shaped aluminum side beams 100.

[0044] The technical solution in the above-mentioned embodiment of the present application has at least the following technical effects or advantages: Compared with the first embodiment, in the present embodiment, after the two C-shaped aluminum side beams 100 are connected to each other through a plurality of snap-fitting protrusions 102, water is injected into the interior of the grouting pipe 202. After the water is injected into the interior of the grouting pipe 202, the water is evenly transported to the compressed wood chip board 201 through the external water outlet 203. After the water enters the compressed wood chip board 201, the water will cause the compressed wood chip board 201, which was originally in a compressed state, to expand and diverge to its original state. When it expands and diverges to its original state, the compressed wood chip board 201 in its original state will gradually fill the gap between the two snap-fitting protrusions 102, thereby filling the gap between the two C-shaped aluminum side beams 100, reducing the shaking space during vibration, and reducing the phenomenon of unstable connection.

[0045] Embodiment 3: Considering that during use, although the compressed wood chip board 201 can fill the gaps between the multiple clamping protrusions 102 after being expanded by water flow, the compressed wood chip board 201 in the expanded state is relatively loose and has poor stability. In view of the above technical problems, the present application proposes the following technical solutions to solve the above technical problems, specifically:

[0046] like Figure 5As shown, a wear-resistant rubber snap-fitting bag 300 is integrally formed on the outside of the grouting pipe 202. The wear-resistant rubber snap-fitting bag 300 is in the shape of an inverted triangle. The sharp corners of the wear-resistant rubber snap-fitting bags 300 on the isosceles sides on both sides of the snap-fitting protrusion 102 are in opposite directions. A plurality of water outlet holes 203 are connected with part of the wear-resistant rubber snap-fitting bags 300. The wear-resistant rubber snap-fitting bags 300 are used to inject adhesive into the limiting groove 200 through the grouting pipe 202, so as to use the adhesive to make a part of the wear-resistant rubber snap-fitting bag 300 expand and to generate a snap connection with the wear-resistant rubber snap-fitting bags 300 with opposite sharp corners. After a part of the wear-resistant rubber snap-fitting bag 300 expands, it will be inserted into the compressed wood chip board 201 that has already expanded and separated, forming an extruded filling inside the compressed wood chip board 201.

[0047] Specifically, during use, when the staff injects water into the grouting pipe 202 to cause the compressed wood chip board 201 to expand and fill the gaps between the multiple snap-in protrusions 102, the staff observes that the compressed wood chip board 201 has fully expanded, and then uses the filling machine to connect the grouting pipe 202 again, and injects adhesive into the grouting pipe 202. After the adhesive is injected into the grouting pipe 202, the adhesive will gradually penetrate into the compressed wood chip board 201 that has expanded and separated through the multiple water outlet holes 203. When the adhesive is dry, the adhesive can solidify the expanded and dispersed compressed wood chip board 201, and the stability between the multiple snap-in protrusions 102 is further increased through the solidified compressed wood chip board 201.

[0048] Furthermore, when the adhesive is injected into the interior of the grouting pipe 202, the adhesive will fill part of the wear-resistant rubber snap-fit ​​bag 300 connected to the water outlet 203, and fill the interior of the grouting pipe 202, so that the interior of multiple wear-resistant rubber snap-fit ​​bags 300 are filled and expanded. When the wear-resistant rubber snap-fit ​​bags 300 expand, they will further squeeze the relatively loose compressed wood chip board 201, so that the compressed wood chip board 201 is more tightly connected when the adhesive is injected, reducing the gap, and further increasing its connection stability and tightness.

[0049] Furthermore, by setting the one-way valve plate 600, during the process of injecting the adhesive, the one-way valve plate 600 can effectively prevent the adhesive and water from flowing back when the staff separates the filling port of the filling machine from the inlet of the grouting pipe 202.

[0050] Furthermore, when the adhesive completely enters into the expanded compressed wood chip board 201 and part of the wear-resistant rubber snap-in capsule 300, part of the wear-resistant rubber snap-in capsule 300 can be filled and the remaining part of the wear-resistant rubber snap-in capsule 300 can be completely expanded. When the wear-resistant rubber snap-in capsule 300 expands, the wear-resistant rubber snap-in capsules 300 on the adjacent snap-in protrusions 102 will contact each other, and the expanded wear-resistant rubber snap-in capsules 300 between the adjacent sides are in opposite directions, realizing the mutual snap-in phenomenon, further reducing the gap between the multiple snap-in protrusions 102, and further increasing the connection stability.

[0051] The technical solution in the above-mentioned embodiment of the present application has at least the following technical effects or advantages: relative to embodiment 2, in this embodiment, the staff can inject adhesive into the interior of the grouting pipe 202, and the adhesive can bond the loose compressed wood chip board 201 when entering the interior of the grouting pipe 202. At the same time, the adhesive remaining in the grouting pipe 202 can fill part of the wear-resistant rubber snap-fit ​​bag 300 after curing, so that the wear-resistant rubber snap-fit ​​bag 300 expands. After the wear-resistant rubber snap-fit ​​bag 300 expands, the loose compressed wood chip board 201 can also be squeezed, so that the connection between the loose compressed wood chip boards 201 is tighter, ensuring the connection stability between the multiple snap-fit ​​protrusions 102.

[0052] Embodiment 4: Considering that the simple wear-resistant rubber snap-fitting capsule 300 is relatively soft in texture, the soft wear-resistant rubber snap-fitting capsule 300 cannot play a good role in fixing and limiting in the process of mutual snapping. Therefore, in view of the above technical problems, the present application proposes the following technical solutions to solve the above technical problems, specifically:

[0053] like Figure 7-Figure 8 As shown, another part of the wear-resistant rubber snap-fit ​​capsule 300 is fixedly connected to a sealing elastic membrane 400 on one side close to the inner wall of the limiting groove 200, and a closed cavity is formed between the sealing elastic membrane 400 and the other part of the wear-resistant rubber snap-fit ​​capsule 300. The closed cavity is filled with a non-Newtonian liquid 401. The non-Newtonian liquid 401 is used to harden during vibration, thereby forming a hardened connection between the wear-resistant rubber snap-fit ​​capsules 300 that are mutually engaged at the sharp ends, thereby improving the connection stability.

[0054] Specifically, during use, non-Newtonian liquid 401 is pre-filled into the partially closed cavity. At the same time, when the water flow causes the compressed wood chip board 201 to diverge and separate, and when the adhesive gradually enters the grouting pipe 202, the partially unsealed wear-resistant rubber snap-fit ​​bag 300 will be filled with adhesive. After the compressed wood chip board 201 diverges and separates, the non-Newtonian liquid 401 in the closed cavity will push the sealing elastic membrane 400 and part of the wear-resistant rubber snap-fit ​​bag 300 to return to their original state.

[0055] like Figure 8 As shown, when all the wear-resistant rubber snap-in capsules 300 are restored to their original state, the wear-resistant rubber snap-in capsules 300 on the adjacent side can be in a mutually snap-in state, and through the setting of the non-Newtonian liquid 401, when the mutually snap-in wear-resistant rubber snap-in capsules 300 are subjected to impact force, the non-Newtonian liquid 401 located inside the closed cavity will harden. The hardened non-Newtonian liquid 401 is combined with the wear-resistant rubber snap-in capsules 300 to avoid the problem that the soft wear-resistant rubber snap-in capsules 300 cannot play a good limiting and fixing role during the mutual snap-in process.

[0056] like Fig. 9 As shown, a portion of the non-Newtonian liquid 401 is filled with magnetic powder 500, and another portion of the non-Newtonian liquid 401 is filled with iron powder. The filling of the magnetic powder 500 and the iron powder causes the adjacent and clamped wear-resistant rubber clamping capsules 300 to approach and attract each other due to the magnetic attraction between the magnetic powder 500 and the iron powder. When approaching and attracting each other, the connection between the clamped wear-resistant rubber clamping capsules 300 becomes more stable.

[0057] Specifically, in order to strengthen the connection tightness between multiple wear-resistant rubber snap-fit ​​capsules 300 in the normal state, magnetic powder 500 can be filled inside part of the non-Newtonian liquid 401, and iron powder can be filled inside another part of the non-Newtonian liquid 401, so that the wear-resistant rubber snap-fit ​​capsules 300 with magnetic powder 500 and iron powder and the non-Newtonian liquid 401 are attracted to each other and approach each other, so that the snap-fit ​​tightness of the wear-resistant rubber snap-fit ​​capsules 300 in the normal state is better.

[0058] The technical solution in the above-mentioned embodiment of the present application has at least the following technical effects or advantages: relative to embodiment three, in this embodiment, a closed cavity is formed by cooperating with a sealing elastic membrane 400 inside a part of the wear-resistant rubber snap-fit ​​capsule 300, and a non-Newtonian liquid 401 is pre-filled inside the closed cavity. The non-Newtonian liquid 401 makes the wear-resistant rubber snap-fit ​​capsule 300 harden during the vibration process. The hardened non-Newtonian liquid 401 cooperates with the wear-resistant rubber snap-fit ​​capsule 300 to strengthen the mutual clamping tightness between multiple wear-resistant rubber snap-fit ​​capsules 300, thereby avoiding the occurrence of unstable clamping.

[0059] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
