Description

Technical Field

[0001] This utility model relates to the field of building support steel structure, specifically a prefabricated exterior wall support structure. Background Technology

[0002] In recent years, with the continuous progress of society, the construction industry has also developed rapidly. Prefabricated buildings have become the mainstream of my country's future construction development. After the prefabricated exterior walls are installed, they should be calibrated in time and temporary diagonal support measures should be taken between them and the floors. Because some projects are steel frame structures, diagonal supports cannot be erected when the prefabricated exterior walls encounter steel beams, thus reducing the convenience of supporting the prefabricated exterior walls.

[0003] Therefore, how to provide a prefabricated exterior wall connection structure that does not require diagonal bracing is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a prefabricated exterior wall support structure to solve the technical problem of convenient connection between the prefabricated exterior wall and the steel beam.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated exterior wall support structure, including steel columns and a wall, the surface of which is coated with a concrete layer, the steel columns being fixedly installed to the concrete layer via two rows of connecting components, the connecting components including embedded parts and connecting plates, each of which has four sets of through holes, the inner side of which is provided with embedded reinforcing bars, and the outer side of which is fixedly welded with connecting parts, the connecting parts being welded and fixed to the steel columns.

[0006] By adopting the above technical solution, a stable connection between the wall and the steel column is ensured, and the load-bearing capacity and wind pressure resistance of the overall structure are improved. At the same time, the connection components include embedded parts and connection plates, each with four sets of through holes, which are connected together by through-hole welding of embedded steel bars. This connection method not only enhances the strength of the connection nodes, but also makes the construction process simpler and faster, improves construction efficiency, and reduces construction costs.

[0007] Furthermore, a right-angle chamfer is formed on the inner side of the through hole, and the embedded steel bar, embedded parts, and connecting plate are welded through the through hole.

[0008] By adopting the above technical solution, it is easier to center and position the pre-embedded steel bars during perforation and plug welding, thereby improving the accuracy and quality of welding.

[0009] Furthermore, the four sets of pre-embedded steel bars are arranged in a rectangular array with a length of 100mm.

[0010] By adopting the above technical solution, this arrangement makes the connection nodes more uniform under stress, avoids excessive local stress, and improves the load-bearing capacity of the connection nodes. At the same time, the length of the pre-embedded steel bar is 100mm, which not only ensures sufficient anchorage length, but also makes construction more convenient and faster, thus improving construction efficiency.

[0011] Furthermore, the two columns of connecting components are arranged in a mirror image along the thickness centerline of the steel column, and each column of connecting components consists of several connecting components arranged at equal intervals.

[0012] By adopting the above technical solutions, the wall is made more uniform and symmetrical when subjected to force, which improves the stability of the overall structure. At the same time, each column of connecting components is composed of several connecting components arranged at equal intervals. This equidistant arrangement allows the connecting nodes to distribute the load more evenly when subjected to force, avoiding the occurrence of local overload.

[0013] Furthermore, the embedded part is a 200x150x10 steel plate, and the connecting part is an L75x50x8 angle steel.

[0014] By adopting the above technical solution, the steel plate of this size and material has sufficient strength and rigidity to withstand large loads and deformations, ensuring the stability of the connection node. At the same time, the connector is an L75x50x8 angle steel. The structural form of the angle steel allows it to withstand both tensile and compressive forces, enhancing the load-bearing capacity of the connection node.

[0015] Furthermore, a supporting angle steel is fixedly welded to the right-angled inner side of the connector, and the connecting plate is a structure of two rectangular steel plates, which are embedded in the inner side of the concrete layer.

[0016] By adopting the above technical solution, the stability and shear resistance of the connection nodes are enhanced, enabling the wall to be more stably supported on the steel columns when subjected to lateral forces. Simultaneously, the connection plate consists of two rectangular steel plates embedded inside the concrete layer. This embedding method creates a strong connection between the connection plate and the concrete layer, improving the overall structure's durability and safety.

[0017] In summary, the present invention has the following main advantages:

[0018] 1. This utility model, through the connecting components, ensures a tight connection between the embedded parts and the connecting plate with four sets of pre-embedded steel bars, effectively transferring the load borne by the wall. At the same time, the outer side of the embedded parts is fixedly welded with connecting parts, which are then welded and fixed to the steel columns, directly and firmly connecting the wall and the steel columns together, enhancing the stability of the overall structure. This not only improves the installation stability of the prefabricated exterior wall but also significantly increases its load-bearing capacity. In addition, it simplifies the construction process, reduces the difficulty and complexity of on-site operations, and thus effectively improves construction efficiency.

[0019] 2. The pre-embedded steel bars of this utility model are connected to the pre-embedded parts and connecting plates by through-hole plug welding, which ensures a tight bond between the steel bars and the pre-embedded parts and connecting plates, forming a stable connection node. This tight bond allows the load to be effectively transferred between the wall and the steel column, improving the overall load-bearing capacity of the structure. At the same time, the through-hole plug welding method also enhances the shear strength and stiffness of the connection node, enabling the structure to remain stable when subjected to lateral forces or vibrations.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0026] Example 1:

[0027] A prefabricated exterior wall support structure, such as Figure 1-4As shown, the structure includes a steel column 1 and a wall 2. The surface of the wall 2 is coated with a concrete layer 3. The steel column 1 is fixedly installed to the concrete layer 3 via two rows of connecting components 4. The connecting components 4 include embedded parts 401 and connecting plates 404. Both the embedded parts 401 and the connecting plates 404 have four sets of through holes 403. Embedded steel bars 402 are inserted through the inner side of the through holes 403. Connecting parts 405 are fixedly welded to the outer side of the embedded parts 401. The connecting parts 405 are welded and fixed to the steel column 1, ensuring a stable connection between the wall 2 and the steel column 1 and improving the overall structure. The structure has a strong load-bearing capacity and wind pressure resistance. Meanwhile, the connecting component 4 includes an embedded part 401 and a connecting plate 404, both of which have four sets of through holes 403. They are connected together by through-hole plug welding of embedded steel bars 402. This connection method not only enhances the strength of the connection node, but also makes the construction process simpler and faster, improves construction efficiency, and reduces construction costs. In addition, a connecting part 405 is fixedly welded to the outside of the embedded part 401. The connecting part 405 is welded and fixed to the steel column 1, which further enhances the connection stability between the wall 2 and the steel column 1.

[0028] Example 2:

[0029] See Figure 3 , Figure 4 The inner side of the through hole 403 has a right-angle chamfer. The embedded steel bar 402 is plugged and welded to the embedded part 401 and the connecting plate 404 through the through hole 403, which makes it easier to center and position the embedded steel bar 402 during the plugging and welding, improving the accuracy and quality of the welding. At the same time, the plugging and welding of the embedded steel bar 402 to the embedded part 401 and the connecting plate 404 through the through hole 403 makes the connection node more robust and reliable, able to withstand larger loads and deformations, and improves the durability and safety of the overall structure.

[0030] See Figure 4 The four sets of pre-embedded steel bars 402 are arranged in a rectangular array with a length of 100mm. This arrangement makes the connection node more uniform under stress, avoids excessive local stress, and improves the load-bearing capacity of the connection node. At the same time, the length of the pre-embedded steel bars 402 is 100mm, which not only ensures sufficient anchorage length, but also makes construction more convenient and faster, improving construction efficiency. In addition, the rectangular array arrangement also makes the connection node more neat and beautiful in appearance, enhancing the overall image of the building.

[0031] See Figure 1 , Figure 2The two rows of connecting components 4 are arranged in a mirror image along the thickness centerline of the steel column 1, and each row of connecting components 4 consists of several connecting components 4 arranged at equal intervals, which makes the wall 2 more uniform and symmetrical when under stress, improving the stability of the overall structure. At the same time, each row of connecting components 4 consists of several connecting components 4 arranged at equal intervals. This equidistant arrangement allows the connection nodes to distribute the load more evenly when under stress, avoiding local overload. In addition, the combination of mirror image arrangement and equidistant arrangement makes construction more convenient and faster, improving construction efficiency and quality.

[0032] See Figure 2 , Figure 3 , Figure 4 The embedded part 401 is a 200x150x10 steel plate, and the connector 405 is an L75x50x8 angle steel. The steel plate of this size and material has sufficient strength and rigidity to withstand large loads and deformations, ensuring the stability of the connection node. At the same time, the connector 405 is an L75x50x8 angle steel. The structure of the angle steel allows it to withstand both tensile and compressive forces, enhancing the load-bearing capacity of the connection node. In addition, the combined use of steel plate and angle steel makes the connection node more aesthetically pleasing and improves the overall image of the building.

[0033] See Figure 2 , Figure 3 , Figure 4 The connector 405 has a supporting angle steel welded to its right-angled inner side. The connecting plate 404 consists of two rectangular steel plates embedded inside the concrete layer 3, enhancing the stability and shear resistance of the connection node. This allows the wall 2 to be more stably supported on the steel column 1 when subjected to lateral forces. Furthermore, the embedded nature of the connecting plate 404 ensures a strong connection between it and the concrete layer 3, improving the overall structure's durability and safety. The combined use of the supporting angle steel and the embedded connecting plate 404 also makes construction more convenient and faster, improving construction efficiency and quality.

[0034] The implementation principle of this embodiment is as follows: The surface of the wall 2 is coated with a concrete layer 3 to enhance its structural strength. The steel column 1 and the concrete layer 3 are fixedly installed through two rows of connecting components 4. The connecting components 4 consist of embedded parts 401 and connecting plates 404, which are connected together by four sets of embedded steel bars 402 through holes and plug welded to form a stable connection node. Connecting parts 405 are also fixedly welded to the outside of the embedded parts 401. The connecting parts 405 are welded to the steel column 1, thereby realizing a firm connection between the wall 2 and the steel column 1. This structural design not only improves the installation stability and load-bearing capacity of the precast exterior wall, but also simplifies the construction process and improves construction efficiency.
