Technical Field
[0001] This utility model relates to the technical field of steel structure connectors, specifically a steel structure factory column base connection component for anti-settlement reinforcement. Background Technology
[0002] As a major steel-producing country, my country has long used steel for factory construction, specifically categorized into light steel and heavy steel structure factories. Column bases are the fundamental components of steel structure factory buildings, primarily used for load-bearing.
[0003] When installing column bases, it is usually necessary to pre-cut grooves in the ground and pour reinforced concrete bases. Several sets of threaded rods extend from the bases to connect with the column bases. In the entire steel structure factory building, apart from the connection with the top beams, the bottoms of the column bases are independent of each other, and the bases themselves have limited volume. Under the weight of the factory building, there is still a certain probability of settlement. When a single column base settles, it will affect the deformation of the beams at the corresponding positions, causing the overall deformation of the factory building and creating safety hazards. Therefore, the column bases do not have the function of preventing settlement.
[0004] Now, a novel anti-settlement reinforcement steel structure column base connection component is proposed to solve the above problems. Utility Model Content
[0005] The purpose of this utility model is to provide a steel structure factory column base connection component for anti-settlement reinforcement, so as to solve the problem mentioned in the background art of not having the function of anti-settlement of column bases.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a steel structure factory column base connection component for anti-settlement reinforcement, comprising a concrete fixed base, a steel outer shell fitted onto the top of the concrete fixed base, four sets of pre-drilled screw holes on the top of the steel outer shell, extension arms welded laterally on the left and right sides of the steel outer shell, two sets of first reinforcing support plates welded to the front and rear ends of the top of the extension arms, external protrusions welded to the front and rear ends of the steel outer shell, three sets of screw through holes opened inside the external protrusions, three sets of threaded rods inserted laterally between the two sets of external protrusions, anti-loosening nuts fitted onto the outside of the threaded rods, a first docking plate welded to one end of the extension arm, multiple sets of first docking screw holes opened inside the first docking screw holes, second reinforcing support plates welded to the front and rear ends of the sides of the first docking screw holes, second docking plates welded to the front and rear ends of the extension arm, multiple sets of second docking screw holes opened inside the second docking plates.
[0007] As a further technical solution of this utility model, the shape and size of the inside of the steel outer shell are adapted to the shape and size of the outside of the concrete fixing base, and the front and rear ends of the concrete fixing base and the steel outer shell are flush.
[0008] As a further technical solution of this utility model, the bottom ends of the steel outer shell and the extension arm are flush, and the vertical center line of the extension arm about the steel outer shell coincides.
[0009] As a further technical solution of this utility model, the steel outer shell and the first reinforcing support plate are welded and fixed, and the top of the first reinforcing support plate is lower than the top of the steel outer shell.
[0010] As a further technical solution of this utility model, the outer diameter of the threaded rod is adapted to the inner diameter of the screw through hole, and the threaded rod passes through the interior of the screw through hole.
[0011] As a further technical solution of this utility model, the extension arm and the second reinforcing support plate are welded and fixed, the top ends of the first reinforcing support plate and the second reinforcing support plate are flush, the first docking plate and the second docking plate have the same shape and size, and the position and size of the first docking screw eye and the second docking screw eye correspond one-to-one.
[0012] Compared with the prior art, the beneficial effects of this utility model are: the anti-settlement reinforcement steel structure factory column base connection component not only realizes the function of anti-settlement of column base, but also realizes the function of tension reinforcement, and also realizes the function of easy docking connection; (1) By setting up a steel outer shell, pre-drilled screw holes, extension arm and first reinforcing support plate, when in use, the concrete fixed base is used as the column foot installation base. The concrete is pre-grooved and poured in the ground. Before installing the column foot, the steel outer shell is hoisted and fitted onto the outside of the concrete fixed base. The bolt rods at the top of the concrete fixed base pass through the pre-drilled screw holes to facilitate the subsequent installation of the column foot. The extension arm extends to both sides to increase the contact area between the concrete fixed base and the ground, thereby increasing its load-bearing capacity and reducing the probability of sinking. The first reinforcing support plate provides top support and reinforcement for the extension arm, improving its structural strength and realizing the function of preventing column foot settlement. (2) By setting out external protrusions, threaded rods, anti-loosening nuts and threaded rod holes, when in use, as the steel outer shell is hoisted and fitted onto the outside of the concrete fixed base, the threaded rods are inserted along the threaded rod holes on the external protrusions and the anti-loosening nuts are tightened for underground reinforcement. Through the traction reinforcement of six sets of threaded rods, the structural stability of the steel outer shell can be further increased, and the function of traction reinforcement is realized. (3) By setting a first docking plate, a first docking screw hole, a second reinforcing support plate, a second docking plate and a second docking screw hole, when in use, the bottom of the two sets of column feet are docked through the extension arm. The first docking plates on the side of the extension arm fit together, and the bolts are driven in along the first docking screw hole to dock.

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.
[0016] Example: Please refer to Figure 1-5 A steel structure factory column base connection component for anti-settlement reinforcement includes a concrete fixed base 1, a steel outer shell 2 sleeved on the top of the concrete fixed base 1, four sets of pre-drilled screw holes 3 on the top of the steel outer shell 2, extension arms 4 are welded laterally on the left and right sides of the steel outer shell 2, and two sets of first reinforcing support plates 5 are welded to the front and rear ends of the top of the extension arms 4 respectively. The internal shape and dimensions of the steel outer shell 2 are compatible with the external shape and dimensions of the concrete fixing base 1. The front and rear ends of the concrete fixing base 1 and the steel outer shell 2 are flush. The bottom ends of the steel outer shell 2 and the extension arm 4 are flush. The vertical center line of the extension arm 4 about the steel outer shell 2 is coincident. The steel outer shell 2 and the first reinforcing support plate 5 are welded and fixed. The top of the first reinforcing support plate 5 is lower than the top of the steel outer shell 2. The extension arm 4 is added on the basis of the base to improve the anti-settlement ability. Specifically, such as Figure 1 and Figure 2 As shown, the concrete fixed base 1 serves as the column foot installation base. It is pre-grooved and poured in the ground. Before installing the column foot, the steel outer shell 2 is hoisted and fitted onto the outside of the concrete fixed base 1. The bolt rods at the top of the concrete fixed base 1 pass through the pre-drilled screw holes 3 to facilitate the subsequent installation of the column foot. The extension arm 4 extends to both sides to increase the contact area between the concrete fixed base 1 and the ground, thereby increasing its load-bearing capacity and reducing the probability of sinking. The first reinforcing support plate 5 provides top support and reinforcement for the extension arm 4, improving its structural strength.
[0017] The steel outer shell 2 has external protrusions 6 welded to both sides of the front and rear ends. The external protrusions 6 have three sets of screw through holes 9 inside. Three sets of threaded rods 7 are horizontally inserted between two sets of external protrusions 6. The threaded rods 7 are fitted with anti-loosening nuts 8. The outer diameter of the threaded rods 7 is matched with the inner diameter of the screw through holes 9. The threaded rods 7 pass through the interior of the screw through holes 9 for easy locking and reinforcement. Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, as the steel outer shell 2 is hoisted and fitted onto the outside of the concrete fixed base 1, the threaded rod 7 is inserted along the threaded rod through hole 9 on the outer protrusion 6, and the anti-loosening nut 8 is tightened for underground reinforcement. Through the traction reinforcement of six sets of threaded rods 7, the structural stability of the steel outer shell 2 can be further increased.
[0018] One end of the extension arm 4 is welded with a first docking plate 10. The first docking plate 10 has multiple sets of first docking screw holes 11 inside. The front and rear ends of the first docking screw holes 11 are respectively welded with second reinforcing support plates 12. The front and rear ends of the extension arm 4 are respectively welded with second docking plates 13. The second docking plates 13 have multiple sets of second docking screw holes 14 inside. The extension arm 4 and the second reinforcing support plates 12 are welded and fixed. The tops of the first reinforcing support plates 5 and the second reinforcing support plates 12 are flush. The first docking plates 10 and the second docking plates 13 have the same shape and size. The positions and dimensions of the first docking screw holes 11 and the second docking screw holes 14 correspond one-to-one, which facilitates docking in pairs. Specifically, such as Figure 1 , Figure 4 and Figure 5As shown, the bottoms of the two sets of column bases are connected by an extension arm 4. The first docking plates 10 on the side of the extension arm 4 fit together, and bolts are driven into the first docking screw holes 11 to connect them. The second reinforcing support plate 12 can increase the structural stability of the first docking plate 10. Multiple column bases of the factory building are also connected underground at the same time, connecting the weight of the individual column bases into a whole, further improving the anti-settlement ability.
[0019] Working Principle: In use, the concrete fixed base 1 serves as the column base, pre-cast in a groove in the ground. Before installing the column base, the steel outer shell 2 is hoisted and fitted onto the outside of the concrete fixed base 1. The bolt rods at the top of the concrete fixed base 1 pass through the pre-drilled screw holes 3 to facilitate subsequent column base installation. The extension arm 4 extends to both sides, increasing the contact area between the concrete fixed base 1 and the ground, thereby increasing its load-bearing capacity and reducing the probability of subsidence. The first reinforcing support plate 5 provides top support and reinforcement for the extension arm 4, enhancing its structural strength. As the steel outer shell 2 is hoisted and fitted onto the outside of the concrete fixed base 1, the threaded rod 7 is inserted along the threaded through hole 9 on the outer protrusion 6 and tightened with the anti-loosening nut 8 for underground reinforcement. Through the traction reinforcement of six sets of threaded rods 7, the structural stability of the steel outer shell 2 can be further increased. The bottoms of the two sets of column bases are connected by an extension arm 4. The first docking plates 10 on the side of the extension arm 4 fit together, and bolts are driven in along the first docking screw holes 11 to connect them. The second reinforcing support plate 12 can increase the structural stability of the first docking plate 10. Multiple column bases of the factory building are also connected underground. The second docking plate 13 and the second docking screw holes 14 provide convenience for corner docking, forming a mesh support underground, connecting the weight of the individual column bases into a whole, and further improving the anti-settlement capacity.
