Description
Technical Field
[0001] The utility model relates to the technical field of column structures, in particular to a structure in which a concrete column end is reinforced by outer-wrapped steel plates and angle steels. Background Art
[0002] A column is the main vertical structural member in a building, supporting the weight of objects above it. It is a basic structure in the construction field. In existing technologies, column structures are mostly made of concrete and have load-bearing capacity.
[0003] However, when a column structure made of pure concrete encounters a high-intensity destruction, the surface may be damaged to a certain extent, or even deformed significantly. Therefore, there is a column structure of an applied steel structure in the prior art, in which angle steels are fixed on the side edges of the column to increase the strength.
[0004] However, in actual use, the angle steel only wraps the side edges of the column, and the increased strength is limited. When encountering damage such as earthquakes or high-intensity impacts, deformation and damage will still occur. The bearing capacity and ductility of the concrete column ends need to be improved. Utility Model Content
[0005] In order to improve the bearing capacity and ductility of the column structure, the present application provides a structure in which the concrete column ends are reinforced with steel plates and angle steels.
[0006] The present application provides a structure for reinforcing concrete column ends with steel plates and angle steels, which adopts the following technical solutions:
[0007] A structure in which the ends of concrete columns are reinforced with steel plates and angle steels, comprising a column, a panel frame and a plurality of angle steels. The angle steels are arranged on the column, and inner plates are provided between adjacent angle steels to connect them. The inner plates abut against the column, and the panel frame is sleeved on the column and connected to the angle steels. The inner wall of the panel frame abuts against the inner plates and the angle steels.
[0008] By adopting the above technical solution, the tips of adjacent angle steels are connected by inner plates, and the inner plates cooperate with the angle steels to form an internal frame to surround the concrete column, thereby improving the bending bearing capacity of the column structure. The internal connecting angle steels improve the stability of the angle steel fixation under the fixed cooperation of the panel frame, and reduce the possibility of the angle steel being impacted and falling off during use. At the same time, the inner plate supports the column. Both the inner plate and the panel frame can be composed of steel sections. While cooperating with the angle steel to further improve the bearing capacity of the column, the wrapping force of the steel plate on the concrete column is improved, the protective force of the column structure surface is improved, the possibility of damage to the column structure surface after collision is reduced, and the vertical bearing capacity and deformation capacity of the column structure are improved. At the same time, the improvement of the column structure strength can improve the overall ductility of the building.
[0009] Preferably, the enclosure frame is composed of a plurality of outer plates connected together, the outer plates are connected to two adjacent angle steels, and the outer plates are pressed against the inner plates and the angle steels.
[0010] By adopting the above technical solution, the steel outer plates are welded to form a panel frame. During installation, the outer plates and the angle steels are welded and fixedly connected so that the inner walls of the outer plates are abutted against the inner plates. Then, the adjacent outer plates are welded and fixedly connected to form a panel frame, thereby further improving the strength of the column structure and the convenience of installation.
[0011] Preferably, the outer plate is provided with a welding groove, and the outer plate is connected to the inner plate.
[0012] By adopting the above technical solution, the bottom side wall of the welding groove can be welded to the inner plate or angle steel through the welding groove, which improves the welding convenience and increases the connection area between the outer plate, the angle steel and the inner plate, thereby improving the stability of the outer plate installation and fixing, thereby ensuring the strength.
[0013] Preferably, the inner plate is provided with a glue injection groove, and the glue injection groove is not communicated with the welding groove.
[0014] By adopting the above technical solution, the surface of the concrete column itself may be uneven. After the angle steel and inner plate are installed, there may be a certain gap between the inner wall of the angle steel or the inner wall of the inner plate and the column. The gap space can be injected with glue through the glue injection groove to fill the gap, so that the column and the inner plate or angle steel are tightly connected, thereby improving the structural strength of the column. The angle steel and inner plate are usually connected to the concrete column by glue. By filling, it can be fully ensured that the inner plate and the angle steel contact the concrete column, so that after the glue evaporates and fixes, the inner plate and the angle steel are fixed to the column. At the same time, the same glue injection groove can be used to observe whether there is glue flowing out to detect whether the glue injection fills the gap. At the same time, the glue injection groove is not connected to the welding groove, so that the surface of the concrete column is not exposed, ensuring surface protection, thereby improving the bending bearing capacity.
[0015] Preferably, the angle steel is provided with a connecting block, the connecting block is inserted into the welding groove, the connecting block is connected to the inner plate, and the connecting block is connected to the outer plate.
[0016] By adopting the above technical solution, the connecting block is inserted into the welding groove and abutted against the welding groove. The connecting block can provide positioning for the installation of the outer plate. At the same time, the connecting block abuts against the inner wall of the welding groove to share the pressure caused by the gravity of the outer plate, limit the outer plate in the vertical direction, and improve the stability of the outer plate connection and installation. The connecting block is welded to the angle steel and the inner plate. The connecting block improves the stability of the connection between the angle steel and the inner plate, reduces the possibility of deformation and cracking caused by excessive force at the connection between the angle steel and the inner plate, thereby improving the durability and strength of the column structure. The welding of the connecting block and the outer plate can increase the connection area between the outer plate and the angle steel, improve the stability of the connection between the outer plate, the angle steel and the inner plate, thereby improving the durability and strength of the column structure.
[0017] Preferably, the connection between adjacent outer plates is located at the back of the angle steel limb.
[0018] By adopting the above technical solution, the tip of the angle steel limb is welded to the inner plate, and the welding position between adjacent outer plates is set at the back of the angle steel limb, which can stagger the positions of the two welds, thereby improving the stability of the connection and the bearing capacity of the column structure.
[0019] Preferably, the angle steel is provided with a connecting rod, the outer plate is provided with a connecting groove, and the connecting rod is inserted into the connecting groove.
[0020] By adopting the above technical solution, the connecting rod is inserted into the connecting groove, and the outer plate is positioned and limited by the connecting rod pressing against the inner wall of the connecting groove, which facilitates the positioning operation when the outer plate is installed on the angle steel. While facilitating the installation of the outer plate, the outer plate is supported to a certain extent by the connecting rod pressing against the inner wall of the connecting groove.
[0021] Preferably, the connecting groove passes through the outer plate, and the connecting rod is connected to the outer plate.
[0022] By adopting the above technical solution, the outer plates are connected by connecting rods, thereby increasing the connection area between the outer plates and the inner wall, and improving the stability of the connection between the outer plates and the angle steel.
[0023] In summary, this application includes at least one of the following beneficial technical effects:
[0024] 1. The columns, enclosure frames, angle steels, inner and outer panels are arranged. The angle steels are arranged at the four corners. The inner panels are connected to the tips of the adjacent angle steels by welding. The four outer panels are welded together in sequence to form the enclosure frame. The enclosure frame surrounds the angle steels and the inner panels. The angle steels and the outer panels are welded together. The welding connection position can be set on the top wall or bottom wall or grooved for welding. The welds between the outer panels are set at the back of the angle steels to avoid the welds between the angle steels and the inner panels. The column is made of concrete. The main body can be cast first and then the angle steels, inner panels and outer panels can be installed in sequence, thereby improving the strength of the column structure and thus improving the ductility of the entire building.
[0025] 2. By setting welding grooves and connecting blocks, the connecting blocks are welded to the angle steel and inner plate to improve the strength of the connection between the angle steel and the inner wall. At the same time, the connecting blocks are inserted into the welding grooves and abutted against the welding grooves. The inner wall of the outer plate is welded to the angle steel and the inner plate through the welding grooves, thereby increasing the welding area and improving the stability of the connection between the outer plate, the angle steel and the inner plate. At the same time, the connecting blocks are welded to the surface of the outer plate, further improving the stability of the outer plate installation, thereby improving the wrapping force of the steel plate on the concrete column, the three-dimensional compressive resistance of the concrete, and improving the bearing capacity of the column;
[0026] 3. By setting up the glue injection groove, the surface of the concrete column itself may have some unevenness. Therefore, after the angle steel and the inner plate are installed, there may be a certain gap between the inner wall of the angle steel or the inner wall of the inner plate and the column. The glue injection groove can be used to inject glue into the gap space between the concrete column, the angle steel and the inner plate to fill the gap, so that the column and the inner plate or the angle steel are tightly connected, thereby improving the overall strength. At the same time, the same glue injection groove can be used to observe whether there is glue flowing out to detect whether the glue injection fills the gap. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following is combined with Figure 1-3 This application is described in further detail.
[0032] The embodiment of the present application discloses a structure in which the end of a concrete column is reinforced with a steel plate and angle steel. Figures 1 to 3It includes a column 1, a panel frame 4 and four long strip angle steels 2. The column 1 is made of concrete. The angle steels 2 are fixed on the four side edges of the column 1 and wrapped with glue or other means. Several steel inner plates 3 are arranged between adjacent angle steels 2. The inner plates 3 are long strips and the two sides of the inner plates 3 are welded and fixedly connected to the tips of the adjacent angle steels 2. The thickness of the inner plates 3 is consistent with the thickness of the side walls of the angle steel 2. The length of the inner plates 3 is about 100mm. Glue injection grooves 31 are formed between adjacent inner plates 3, and the inner side walls of the inner plates 3 are pressed against the surface of the column 1. The panel frame 4 is put on the column 1. The panel frame 4 is composed of four steel outer plates 41. The outer plates 41 are pressed against the outer walls of the angle steel 2 and the outer walls of the inner plates 3. The outer plates 41 are welded and fixedly connected to the angle steel 2 and the inner plates 3. The two adjacent outer plates 41 are welded and fixedly connected, and the weld is set at the back of the angle steel 2. By setting up an inner plate 3 to fix the adjacent angle steels 2 and cooperating with the outer plate 41 to surround the surface of the column 1, the surface protection of the column 1 is improved. At the same time, through a circle of steel structure and welding connection, the vertical bearing capacity of the column 1 is improved, thereby improving the column structure strength and the deformation capacity of the column end.
[0033] In order to improve the stability of the installation of the outer plate 41, refer to Figure 1 and Figure 2 The outer panel 41 is provided with a plurality of welding grooves 411 that are not connected to the glue injection grooves 31. The welding grooves 411 are located away from the connection positions of other external connectors. The welding grooves 411 are staggered with the inner panel 3. The length of the welding grooves 411 is arranged in the horizontal direction and is longer than the length of the inner panel 3. A connecting block 21 is provided at the connection between the angle steel 2 and a portion of the inner panel 3. The connecting block 21 is welded and fixedly connected to the angle steel 2 and a portion of the inner panel 3. The connecting block 21 is adapted to be inserted into the welding grooves 411, and the outer wall of the connecting block 21 is flush with the outer wall of the outer panel 41. The connecting block 21 is welded and fixedly connected to the outer panel 41. In another embodiment, the connecting block 21 is adapted to fill the welding grooves 411 to improve the overall flatness of the outer panel 41 surface. The outer panels 41 are provided with connecting grooves 412 extending through the side walls. Several L-shaped connecting rods 5 are welded to the outer walls of the angle steel 2. These rods 5 fit into the connecting grooves 412 on the two connected outer panels 41. The outer walls of the connecting rods 5 are flush with the outer walls of the outer panels 41, and the connecting rods 5 are welded to the outer panels 41. A circle of welds around the weld grooves 411 securely connects the outer panels 41 to the angle steel 2 and inner panels 3, while also securing the bottom of the welded connecting block 21 to the inner side of the outer panels 41, thus completing the secure installation of the outer panels 41. The provision of multiple weld grooves 411 increases the weld area between the outer panels 41, the angle steel 2, and the inner panels 3, thereby improving the stability of the outer panel 41 installation.
[0034] The implementation principle of the structure of a concrete column end reinforced with steel plates and angle steels in the embodiment of the present application is as follows: a plurality of inner plates 3 are used to connect adjacent angle steels 2, and a panel frame 4 composed of outer plates 41 is provided, thereby forming a double-layer protective column body 1, which completely wraps the surface of the column body 1, thereby improving the surface protection and bending bearing capacity of the column structure. At the same time, the inner plates 3 and outer plates 41 made of steel plates improve the overall strength, forcing the internal concrete to be compressed in three directions, thereby improving the concrete strength. The inner plates 3 connect adjacent angle steels 2, improving the installation stability of the angle steels 2 while strengthening the bending bearing capacity of the internal surrounding structure. At the same time, the outer plates 41 are connected to the angle steels 2 and the inner plates 3 at multiple welding points, thereby further improving the vertical bearing capacity of the column structure through the steel structure. The internal steel sleeve formed by welding the angle steels 2 and the inner plates 3, and the panel frame 4 formed by welding the outer plates 41, are also welded together between the two layers of steel structure, thereby improving the vertical bearing capacity and bending bearing capacity, thereby improving the strength of the column structure and thereby improving the ductility of the entire building.
[0035] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
