Description

A connection structure between the base of a steel column and a composite slab in a steel structure. Technical Field

[0001] This utility model relates to the field of steel structure technology, specifically to a connection structure between the base of a steel column and a composite plate in a steel structure. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. They are mainly composed of steel beams, steel columns, steel trusses, and other components made of steel sections and plates, and are treated with rust removal and prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. The components or parts are usually connected by welds, bolts, or rivets.

[0003] In existing technologies, the lower end of the corner where the composite slab meets the steel column is generally a right angle. However, because there are welds between the steel column and the steel beam, the right angle cannot be combined with the weld when the composite slab falls onto the steel beam, which can easily cause the edges and corners to warp, leading to instability of the steel structure and construction difficulties. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a connection structure between the base of a steel column and a composite slab in a steel structure. This structure has advantages such as a smooth surface without warping edges or corners at the junction of the steel column and the composite slab, and solves the following technical problem: the lower end of the corner where the composite slab and the steel column are located is generally a right angle. However, due to the weld between the steel column and the steel beam, the right angle cannot be combined with the weld when the composite slab falls onto the steel beam, which easily causes warping edges and corners, leading to instability of the steel structure and difficulties in construction.

[0005] To achieve the above objectives, this utility model provides a connection structure between the base of a steel column and a composite slab in a steel structure. The structure includes a column, with a first support plate fixed on each of the four sides of the column. A second support plate is fixed on each of the four sides of the column below the first support plate. A composite slab body is fixed between the first and second support plates. The side of the composite slab body facing the column has a bevel angle. The top and bottom of the left and right sides of the column are provided with reinforcing mechanisms to enhance the stability of the first and second support plates.

[0006] The reinforcing mechanism includes four positioning blocks, four first mounting blocks, four second mounting blocks, four support rods, and several high-strength bolts. The four positioning blocks are fixed to the top and bottom of the left and right sides of the column. The four first mounting blocks have positioning grooves on the side facing the column. The four support rods are fixed between the opposite sides of the first and second mounting blocks. The upper and lower ends of the left side of the first mounting blocks and the left and right ends of the upper surface of the second mounting blocks have threaded holes. The high-strength bolts are threadedly connected to the threaded holes.

[0007] By adopting this technical solution, the joint between the column and the composite slab body is made flat and without any warped edges or corners, thereby improving the stability of the steel structure.

[0008] Furthermore, the positioning block is shaped like a triangular prism, and the dimensions of the inner cavity of the positioning groove are adapted to the dimensions of the positioning block.

[0009] By adopting this technical solution, the position of the first mounting plate can be located, which facilitates installation.

[0010] Furthermore, the angle between the support rod and the first mounting block and the second mounting block is an acute angle, and the inner cavity of the support rod is fixed with reinforcing ribs.

[0011] By adopting this technical solution, the added reinforcing ribs improve the strength of the support rod, thereby extending its service life.

[0012] Furthermore, threaded grooves are provided on both sides of the column, on both ends of the upper surface of the first support plate, and on both ends of the lower surface of the second support plate. The other side of the high-strength bolt passes through the threaded hole and extends into the inner cavity of the threaded groove.

[0013] By adopting this technical solution, the threaded groove facilitates the screwing of high-strength bolts into the threaded groove through the threaded hole, thereby fixing the first and second support plates.

[0014] Furthermore, limiting members are provided at both ends of the inner cavity of the second mounting block, and the limiting members are used to limit the second mounting block.

[0015] By adopting this technical solution, the limiting component facilitates the installation of the second mounting block.

[0016] Furthermore, the limiting component includes two sliders, two connecting plates, and two threaded rods. Fixed cavities are provided at both ends of the inner cavity of the second mounting block. The sliders are slidably connected to the fixed cavities. The two connecting plates are fixed on the opposite sides of the two sliders. The opposite sides of the two connecting plates penetrate the second mounting block and extend to the side away from the second mounting block. The threaded rods are rotatably connected to one side of the connecting plate through bearings.

[0017] Furthermore, the slider moves linearly up and down within the fixed cavity and does not separate from each other, and guide holes adapted to the size of the connecting plate are provided on both the left and right sides of the second mounting block.

[0018] Furthermore, mounting grooves are provided at both ends of the opposite sides of the first support plate and the second support plate, and the threaded rod is threadedly connected to the mounting groove.

[0019] By adopting this technical solution, it is easy to fix the second mounting block to the first support plate and the second support plate.

[0020] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0021] The connection structure between the steel column base and the composite slab of this steel structure adopts a bevel at the joint between the column weld and the composite slab body, and the bevel angle is cut to 45 degrees. This facilitates the joint between the composite slab body and the weld, making the joint between the column and the composite slab body flat and without warping edges or corners, thereby improving the stability of the steel structure. In addition, the reinforcement mechanism can strengthen the first and second support plates, thereby improving the stability of the first and second support plates. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please refer to Figure 1. In this embodiment, the connection structure between the steel column base and the composite slab includes a column 1. First support plates 2 are fixed to all four sides of the column 1. Second support plates 3 are fixed to the lower sides of the first support plates 2 on all four sides of the column 1. A composite slab body 4 is fixed between the first support plates 2 and the second support plates 3. The composite slab body 4 has a slope angle 5 on the side facing the column 1. Reinforcing mechanisms 6 are provided at the top and bottom of both sides of the column 1 to enhance the stability of the first support plates 2 and the second support plates 3.

[0029] It should be noted that by using a bevel angle 5 at the joint between the weld of column 1 and the composite plate body 4, and cutting the angle of bevel angle 5 to 45 degrees, the joint between the composite plate body 4 and the weld is facilitated, and the joint between column 1 and composite plate body 4 is flat and without warping edges or corners.

[0030] Please refer to Figures 2 and 3. To improve the stability of the first support plate 2 and the second support plate 3, the reinforcing mechanism 6 in this embodiment includes four positioning blocks 61, four first mounting blocks 62, four second mounting blocks 63, four support rods 64, and several high-strength bolts 65. The four positioning blocks 61 are fixed to the top and bottom of the left and right sides of the column 1. Each of the four first mounting blocks 62 has a positioning groove 66 on the side facing the column 1. The four support rods 64 are fixed between the opposite sides of the first mounting blocks 62 and the second mounting blocks 63. Threaded holes 67 are opened at the upper and lower ends of the left side of the first mounting block 62 and at the left and right ends of the upper surface of the second mounting block 63. The high-strength bolts 65 are threaded into the threaded holes 67. The first mounting block 62 can be fitted onto the outer surface of the positioning block 61, so that the positioning groove 66 on one side of the first mounting block 62 fits onto the outside of the positioning block 61. Then, two high-strength bolts 65 are screwed into the threaded groove through the threaded holes 67, thereby fixing the first support plate 2 to the column 1.

[0031] In this embodiment, the positioning block 61 is shaped like a triangular prism, and the dimensions of the inner cavity of the positioning groove 66 are adapted to the dimensions of the positioning block 61. The angle between the support rod 64 and the first mounting block 62 and the second mounting block 63 is an acute angle, and a reinforcing rib is fixed to the inner cavity of the support rod 64. The reinforcing rib provided in the inner cavity of the support rod 64 improves the strength of the support rod 64.

[0032] Threaded grooves are provided on both sides of the column 1, at both ends of the upper surface of the first support plate 2, and at both ends of the lower surface of the second support plate 3. The other side of the high-strength bolt 65 passes through the threaded hole 67 and extends into the inner cavity of the threaded groove. Limiting members 68 are provided at both ends of the inner cavity of the second mounting block 63 to limit the second mounting block 63.

[0033] Referring to Figure 4, to facilitate the fixing of the second mounting block 63 to the first support plate 2 and the second support plate 3, the limiting member 68 in this embodiment includes two sliders 682, two connecting plates 683, and two threaded rods 684. Fixed cavities 681 are provided at both ends of the inner cavity of the second mounting block 63. The sliders 682 are slidably connected to the fixed cavities 681. Moving the connecting plates 683 towards the side closer to the first and second support plates 3 causes the sliders 682 to move within the fixed cavities 681. The two connecting plates 683 are fixed to the opposite sides of the two sliders 682, and both opposite sides of the connecting plates 683 penetrate the second mounting block 63 and extend away from it. The threaded rods 684 are rotatably connected to one side of the connecting plates 683 via bearings. Rotating the threaded rods 684 screws into the inner cavity of the mounting groove, thereby fixing the second mounting block 63 onto the first and second support plates 3.

[0034] In this embodiment, the slider 682 moves linearly up and down in the inner cavity of the fixed cavity 681 and does not separate from each other. The left and right sides of the second mounting block 63 are provided with guide holes that are adapted to the size of the connecting plate 683. The left and right ends of the opposite side of the first support plate 2 and the second support plate 3 are provided with mounting grooves. The threaded rod 684 is threadedly connected to the mounting groove.

[0035] Understandably, by screwing the high-strength bolts 65 into the threaded groove through the threaded holes 67, the fixing stability of the first and second support plates 3 can be strengthened, thereby improving the stability of the steel structure.

[0036] The working principle of the above embodiments is as follows:

[0037] By using a bevel angle 5 at the joint between the weld of column 1 and the composite plate body 4, and cutting the angle of bevel angle 5 to 45 degrees, it is easier to join the composite plate body 4 with the weld, so that the joint between column 1 and composite plate body 4 is flat and without warping edges or corners. To improve the stability of the first support plate 2 and the second support plate 3 fixed to the column 1, the first mounting block 62 can be fitted onto the outer surface of the positioning block 61, so that the positioning groove 66 opened on one side of the first mounting block 62 fits onto the outer side of the positioning block 61. Then, two high-strength bolts 65 are screwed into the threaded groove through the threaded hole 67, thereby fixing the first support plate 2 to the column 1. Then, the connecting plate 683 is moved closer to the first and second support plates 3. The movement of the connecting plate 683 drives the slider 682 to move in the inner cavity of the fixing cavity 681. Then, the threaded rod 684 is rotated to screw the threaded rod 684 into the inner cavity of the mounting groove, thereby fixing the second mounting block 63 onto the first and second support plates 3. Then, the high-strength bolts 65 are screwed into the threaded groove through the threaded hole 67, thereby strengthening the fixing stability of the first and second support plates 3. Reinforcing ribs are set in the inner cavity of the support rod 64 to improve the strength of the support rod 64.
