Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of steel structure connection devices, in particular to a connection device for steel structures with an anti-corrosion function. Background Technique
[0002] A steel structure is a structure mainly composed of steel materials and is one of the main building structure types. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of sections and steel plates. Welds, bolts or rivets are usually used to connect between the components or parts. Because of its light self-weight and simple construction, it is widely used in large factories, stadiums, super high-rise buildings and other fields. And the connecting piece is a connecting tool between steel structure components and plays an indispensable and important role in the connection and use of steel structure components. Therefore, the performance of the connecting piece is crucial.
[0003] For the existing connection device for steel structures, when connecting and assembling two groups of steel members, connecting plates are mostly used, and screw holes are opened at corresponding positions on the surfaces of the plates and the steel members, and then washers and bolt nuts are used for locking and fixing. However, in this way, the bearing capacity of the connection structure is relatively small and the applicable range is single. At the same time, opening screw holes on the steel structure is likely to cause weakening of the component cross-section, and the screws will become loose under long-term dynamic load, which is likely to cause the connection at the joint to be not tight.
[0004] Therefore, in view of this, research and improvement are carried out on the existing structural deficiencies, and a connection device for steel structures with an anti-corrosion function is proposed. Content of the Utility Model
[0005] The purpose of the utility model is to provide a connection device for steel structures with an anti-corrosion function to solve the problems raised in the above background technique.
[0006] To achieve the above purpose, the utility model provides the following technical solution: A connection device for steel structures with an anti-corrosion function, including a connection cylinder, ring plates are fixedly installed on both the left and right sides of the outer surface of the connection cylinder, assembly plates are arranged on the opposite sides of the surfaces of the ring plates, screw holes one are opened at corresponding positions on the protruding block parts of the assembly plates and the surfaces of the ring plates, locking bolts are threadedly connected to the inner surfaces of the screw holes one, fixing mechanisms are fixedly installed on both the upper and lower sides of the surfaces of the assembly plates away from the ring plates, and both the connection cylinder and the assembly plates are made of stainless steel and a paint layer is coated on the surface.
[0007] Preferably, the fixing mechanism includes elastic plates fixedly installed on both the upper and lower sides of the surfaces of the assembly plates away from the ring plates, fixing plates are fixedly installed at the ends of the elastic plates away from the assembly plates, and both the fixing plates and the elastic plates are made of stainless steel and a paint layer is coated on the surface.
[0008] Preferably, the fixing mechanism further includes protruding plates fixedly installed on both the left and right sides of the surface of the fixing plate, and screw holes II are formed on the surfaces of the protruding plates.
[0009] Preferably, the fixing mechanism further includes fastening bolts threadedly connected inside the screw holes II, and the fastening bolts penetrate through the screw holes II of the two corresponding protruding plates above and below.
[0010] Preferably, steel structural members are inserted and arranged on both the left and right sides of the inner surface of the connecting cylinder, and one end of the steel structural member extending out of the connecting cylinder penetrates through the middle cavity of the assembly plate and the middle part of the covering cavity formed by the upper and lower fixing plates.
[0011] Preferably, a counterbore is formed around the screw hole I on the surface of the ring plate close to the assembly plate side, and the diameter of the counterbore is larger than that of the screw hole I.
[0012] Preferably, a sealing gasket is embedded inside the counterbore, and the diameter of the sealing gasket matches that of the counterbore, and the inner diameter matches that of the screw hole I.
[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0014] 1. Through the settings of the connecting cylinder, ring plate, assembly plate, screw hole I, locking bolt and fixing mechanism, the overall fixed installation method does not require drilling holes on the surface of the steel structural member, preventing the problem that the cross-section of the member is weakened by the method of opening screw holes on the surface of the steel structural member for connection, and the screws under long-term dynamic load will become loose, resulting in loose connection at the joint and causing safety accidents. Moreover, the main connecting parts in this device are made of stainless steel and coated with a paint layer, making it not easy to rust and rot during use;
[0015] 2. Through the settings of the counterbore and the sealing gasket, the counterbore sinks towards the inner side of the ring plate, enabling the sealing gasket to be installed in a sunken manner, thereby avoiding a large joint generated after the assembly plate and the ring plate are connected, reducing the generation of gaps, enabling the assembly plate and the ring plate to be more closely fitted, and at the same time, the sealing gasket can cover and seal the joint where the locking bolt penetrates through the two plate bodies, preventing the bolts at the gap from rusting, and the soft rubber material of the sealing gasket itself can buffer a certain dynamic load, increasing the stability of the locking bolt assembly and tightening.

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0021] As Figures 1 - 3 shown, a connecting device for a steel structure with an anti-corrosion function includes a connecting cylinder 1. Ring plates 2 are fixedly installed on both the left and right sides of the outer surface of the connecting cylinder 1. Assembly plates 3 are arranged on the opposite sides of the surfaces of the ring plates 2. First screw holes 4 are provided at the corresponding positions of the protruding block parts of the assembly plates 3 and the surfaces of the ring plates 2. Locking bolts 5 are threadedly connected to the inner surfaces of the first screw holes 4. Fixed mechanisms 6 are fixedly installed on both the upper and lower sides of the surfaces of the assembly plates 3 away from the ring plates 2. The connecting cylinder 1 and the assembly plates 3 are both made of stainless steel and are coated with a paint layer on the surface.
[0022] By adopting the above technical solutions, the paint layer on the surfaces of the connecting cylinder 1 and the assembly plates 3 and their own stainless steel materials make the connecting cylinder 1 and the assembly plates 3 not easily rust and corrode; the assembly plates 3 are aligned with the ring plates 2 by using the first screw holes 4, and then locked by using the locking bolts 5 to fix the assembly plates 3 to the connecting cylinder 1, so that the fixed mechanisms 6 can be fixedly assembled with the connecting cylinder 1 to form a complete connecting device part;
[0023] The fixed mechanism 6 fixes the steel structure member 7 to the assembly plate 3, and the assembly plate 3 is fixed to the connecting cylinder 1, that is, the steel structure member 7 is fixed to the entire connecting device.
[0024] Furthermore, the fixed mechanism 6 includes elastic plates 601 fixedly installed on both the upper and lower sides of the surfaces of the assembly plates 3 away from the ring plates 2. Fixed plates 602 are fixedly installed at the ends of the elastic plates 601 away from the assembly plates 3. The fixed plates 602 and the elastic plates 601 are both made of stainless steel and are coated with a paint layer on the surface.
[0025] By adopting the above technical solutions, the elastic plates 601 have a certain degree of deformability and tortuosity, and can drive the fixed plates 602 to move and expand, which is convenient for the installation of the steel body.
[0026] Further, the fixing mechanism 6 further includes protruding plates 603 fixedly installed on both the left and right sides of the surface of the fixing plate 602, and screw holes two 604 are formed on the surfaces of the protruding plates 603.
[0027] Further, the fixing mechanism 6 further includes fastening bolts 605 threadedly connected inside the screw holes two 604, and the fastening bolts 605 penetrate through the screw holes two 604 of the two corresponding upper and lower protruding plates 603.
[0028] Further, steel structure members 7 are inserted and arranged on both the left and right sides of the inner surface of the connecting cylinder 1, and one end of the steel structure member 7 extending out of the connecting cylinder 1 penetrates through the middle cavity of the assembly plate 3 and the middle part of the covering cavity formed by the upper and lower fixing plates 602.
[0029] By adopting the above technical solutions, the steel structure member 7 is inserted into the middle of the upper and lower fixing plates 602, and the upper and lower fixing plates 602 are covered outside the steel structure member 7. By screwing the fastening bolt 605 through the screw hole two 604 of the protruding plate 603, the upper and lower fixing plates 602 can be locked, so that the fixing plate 602 tightly covers and fixes the steel structure member 7.
[0030] Further, a sink 8 is formed around the screw hole one 4 on the surface of the ring plate 2 close to the assembly plate 3 side, and the diameter of the sink 8 is larger than that of the screw hole one 4;
[0031] A sealing washer 9 is embedded and installed inside the sink 8. The diameter of the sealing washer 9 matches that of the sink 8, and the inner diameter matches that of the screw hole one 4.
[0032] By adopting the above technical solutions, the sink 8 sinks towards the inner side of the ring plate 2, so that the sealing washer 9 is installed in a sunken manner, thereby avoiding a large joint after the assembly plate 3 and the ring plate 2 are connected and reducing the generation of gaps;
[0033] The sealing washer 9 can cover and seal the joint where the locking bolt 5 of the two plate bodies penetrates, preventing the bolts at the gap from rusting. The soft rubber material of the sealing washer 9 itself can buffer a certain load force, increasing the stability of the assembly and locking of the locking bolt 5.
[0034] Working principle: When using the connecting device for steel structures with anti-corrosion function, first, install the sealing washer 9 inside the sunk groove 8. Then, align the assembly plate 3 with the ring plate 2 through the first screw hole 4, and lock them tightly with the locking bolt 5 to fix the assembly plate 3 to the connecting cylinder 1. Then, insert the steel structure member 7 into the middle of the upper and lower fixing plates 602 and penetrate through the through cavity in the middle of the assembly plate 3 and insert it into the connecting cylinder 1. After inserting to the specified depth, at this time, the upper and lower fixing plates 602 are wrapped around the outside of the steel structure member 7. Thread the fastening bolt 605 through the second screw hole 604 of the protruding plate 603 to lock the upper and lower fixing plates 602, so that the fixing plates 602 tightly wrap and fix the steel structure member 7, fix the steel structure member 7 and the assembly plate 3, and the assembly plate 3 is fixed to the connecting cylinder 1, that is, the steel structure member 7 is fixed to the entire connecting device. This is the working principle of the connecting device for steel structures with anti-corrosion function.
