Description

Technical Field

[0001] This utility model relates to the field of load-bearing beams, specifically a deformation-resistant composite structure load-bearing beam. Background Technology

[0002] Load-bearing beams refer to those beams that play a supporting and load-bearing role in the building structure. Beams are beams that run parallel to the transverse walls in a building and are mainly used to support the weight of the floor slabs and roof and transfer this weight to the walls or columns.

[0003] However, the current load-bearing beams still have some shortcomings. The existing load-bearing beams have not fully considered the anti-deformation structure. If the load-bearing beams do not fully consider the anti-deformation structure during use, structural deformation and collapse may occur during subsequent use, causing great safety hazards, seriously affecting the service life of the load-bearing beams, and making it inconvenient for workers to use the anti-deformation composite structure load-bearing beams. Utility Model Content

[0004] The purpose of this utility model is to provide a deformation-resistant composite structure load-bearing beam to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a deformation-resistant composite structure load-bearing beam, comprising a supporting beam, a fixing frame, and a mounting frame. The supporting beam is an I-shaped structure and is composed of composite components, including a high-strength wing plate, a high-strength web plate, a honeycomb aluminum core material, and an adhesive. The fixing frame is located on the outer side of the end of the supporting beam, and the end of the supporting beam is provided with connecting bolts. The supporting beam is fixedly connected to the fixing frame by the connecting bolts. The mounting frame is welded to the outer wall of the fixing frame, and the surface of the mounting frame is provided with mounting bolts. A fixing protrusion is welded to the rear side of the mounting frame.

[0006] Furthermore, the high-strength wing plates are disposed on the upper and lower sides of the supporting crossbeam, and high-strength web plates are welded between the high-strength wing plates.

[0007] Furthermore, both the high-strength wing plate and the high-strength web plate are metal alloy structures, and the inner side of the high-strength web plate is provided with a honeycomb aluminum core material.

[0008] Furthermore, an adhesive is provided at the connection between the honeycomb aluminum core and the high-strength web, and the honeycomb aluminum core is bonded to the high-strength web by the adhesive.

[0009] Furthermore, a metal connector is fixedly connected to the inner side of the end of the supporting beam, and circular holes are provided on both sides of the metal connector, and the metal connector is connected to the connecting bolt through the circular holes.

[0010] Furthermore, the number of mounting bolts is eight, and the eight mounting bolts are arranged in pairs, with the four pairs of mounting bolts arranged in a centrally symmetrical structure on the four sides of the mounting frame.

[0011] Furthermore, buffer pads are provided on the outer sides of both the connecting bolts and the mounting bolts, and the buffer pads are engaged with the supporting crossbeam and the surface of the mounting frame.

[0012] Furthermore, there are two fixed protrusions, which are welded to the rear sides of the fixed frame respectively.

[0013] This utility model provides a deformation-resistant composite structure load-bearing beam, which has the following beneficial effects:

[0014] 1. This utility model is equipped with a composite component. During the use of the load-bearing beam, the high-strength flange and high-strength web of the metal alloy structure bear the bending stress. The honeycomb aluminum core material inside the high-strength web transmits shear force and prevents buckling. The honeycomb aluminum core material is bonded to the high-strength web with an adhesive. The adhesive disperses the load across the entire bonding surface, avoiding the stress concentration phenomenon of traditional mechanical connections, improving the overall load-bearing capacity of the structure, enhancing the deformation resistance of the load-bearing beam, extending the service life of the load-bearing beam, and preventing structural deformation and collapse during subsequent use. It also facilitates the use of the deformation-resistant composite structure load-bearing beam by the staff.

[0015] 2. This utility model is equipped with a fixed frame. During the use of the load-bearing beam, the end of the support beam is connected to the fixed frame using connecting bolts, and the fixed protrusion is fixed using concrete or cement structures, thereby completing the fixation of the fixed frame. This ensures the stability of the load-bearing beam, facilitates the secure installation of the load-bearing beam by workers, and prevents the structural connection from loosening during subsequent use. This makes the subsequent use of the load-bearing beam safer and facilitates the use of the anti-deformation composite structure load-bearing beam by workers. Attached Figure Description

[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0021] like Figures 1-3 As shown, a deformation-resistant composite structure load-bearing beam includes a support beam 1, a fixing frame 3, and an mounting frame 6. The support beam 1 has an I-shaped structure and is composed of a composite component 2. The composite component 2 includes a high-strength wing plate 201, a high-strength web plate 202, a honeycomb aluminum core material 203, and an adhesive 204. The high-strength wing plate 201 is disposed on the upper and lower sides of the support beam 1, and the high-strength web plate 202 is welded between the high-strength wing plates 201. Both the high-strength wing plate 201 and the high-strength web plate 202 are metal alloy structures, and the honeycomb aluminum core material 203 is disposed on the inner side of the high-strength web plate 202. The connection between the honeycomb aluminum core material 203 and the high-strength web plate 202 is provided with adhesive 204, and the honeycomb aluminum core material 203 is bonded to the high-strength web plate 202 through the adhesive 204.

[0022] The specific operation is as follows: the high-strength flange 201 and high-strength web 202 of the metal alloy structure bear the bending stress. The honeycomb aluminum core material 203 set inside the high-strength web 202 transmits shear force and prevents buckling. The honeycomb aluminum core material 203 is bonded to the high-strength web 202 by adhesive 204, which makes it convenient for workers to use the anti-deformation composite structure load-bearing beam.

[0023] like Figures 1-3As shown, the fixed frame 3 is located on the outer side of the end of the supporting beam 1, and the end of the supporting beam 1 is provided with connecting bolts 4. The supporting beam 1 is fixedly connected to the fixed frame 3 through the connecting bolts 4. The inner side of the end of the supporting beam 1 is fixedly connected with metal connectors 5, and the metal connectors 5 have circular holes on both sides. The metal connectors 5 are connected to the connecting bolts 4 through the circular holes. The mounting frame 6 is welded to the outer wall of the fixed frame 3, and the surface of the mounting frame 6 is provided with mounting bolts 7. There are eight mounting bolts 7, which are arranged in pairs. The four groups of mounting bolts 7 are arranged in a centrally symmetrical structure on the four sides of the mounting frame 6. The outer side of the connecting bolts 4 and the mounting bolts 7 are provided with buffer pads 8, which are engaged with the supporting beam 1 and the surface of the mounting frame 6. The rear side of the mounting frame 6 is welded with two fixed protrusions 9, which are welded to the two rear sides of the fixed frame 3 respectively.

[0024] The specific operation is as follows: the worker inserts the end of the support beam 1 into the inside of the fixed frame 3, and then uses the connecting bolt 4 to connect the end of the support beam 1 to the fixed frame 3. The connecting bolt 4 passes through the metal connector 5 that is fixedly connected to the inside of the end of the support beam 1 to ensure that the support beam 1 is fixed firmly. Then, using the fixing protrusions 9 welded on both sides of the rear of the fixed frame 3, the fixed frame 3 is installed in a suitable position, and the fixing protrusions 9 are fixed with concrete cement or other structures to complete the fixing of the fixed frame 3. The mounting frame 6 welded to the outer wall of the fixed frame 3 is installed using the mounting bolt 7 to ensure the stable installation of the fixed frame 3, thereby ensuring the stability of the load-bearing beam and facilitating the worker's use of the anti-deformation composite structure load-bearing beam.

[0025] In summary, this anti-deformation composite structure supports the crossbeam according to... Figures 1-3In the structure shown, during the use of the load-bearing beam, firstly, the high-strength flange 201 and high-strength web 202 of the metal alloy structure bear the bending stress. The honeycomb aluminum core 203 inside the high-strength web 202 transmits shear force and prevents buckling. The honeycomb aluminum core 203 is bonded to the high-strength web 202 with adhesive 204. Then, the worker extends the end of the support beam 1 into the inside of the fixed frame 3, and then uses connecting bolts 4 to connect the end of the support beam 1 to the fixed frame 3. The metal connector 5, which is fixedly connected to the inner side of the end of beam 1, is passed through to ensure the stability of the supporting beam 1. Then, the fixing protrusions 9 welded on both sides of the rear of the fixing frame 3 are used to install the fixing frame 3 in a suitable position, and the fixing protrusions 9 are fixed with concrete cement or other structures to complete the fixing of the fixing frame 3. The mounting frame 6 welded to the outer wall of the fixing frame 3 is installed with mounting bolts 7 to ensure the stable installation of the fixing frame 3, thereby ensuring the stability of the load-bearing beam and facilitating the use of the anti-deformation composite structure load-bearing beam by the staff.
