Description

Technical Field

[0001] This utility model belongs to the technical field of steel structure components, specifically relating to a steel structure building connector for buildings. Background Technology

[0002] Steel structure is a building structure constructed primarily of steel. There are many types of steel structures, one of which is square tube steel structure. It is a steel structure that uses square tubes (steel tubes with rectangular or square cross-sections) as the main load-bearing components and is widely used in construction, bridges, machinery manufacturing, and other fields. Steel structure connectors are components used to connect adjacent square tube steel structures into a whole, which play a role in reinforcing the integrity and stability of the structure and transferring loads. The authorized document with announcement number CN222332971U discloses a steel structure connector, which is a conventional component.

[0003] When using steel structure connectors to connect adjacent square tubes, the square tubes are generally inserted into the connectors and secured with bolts. The outer surface of the square tube is in contact with the inner surface of the connector, resulting in a small contact area and few support points for the square tube. In this method, the bolts are exposed and easily loosened by vibration, leading to reduced bolt tightness. In addition, in humid environments, the bolts come into contact with moisture molecules in the outside air, which can cause corrosion and rust. The square tube ends also have few support points and are not shielded, which are drawbacks.

[0004] Existing connectors used to connect adjacent square tube steel structures have the problem of not adding support points to the ends of the square tubes. To address this, this application proposes a steel structure connector for building construction. Utility Model Content

[0026] 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.

[0027] Please see Figures 1 to 5 This utility model provides a technical solution: a steel structure building connector, including a sleeve connector 1 for connecting square tube steel structures, wherein a bolt post 13 penetrates the top surface of the sleeve connector 1. Figure 1In this design, A and B are adjacent square tubes. When adjacent square tubes A and B are connected, they are inserted into the interior of the sleeve connector 1 and reinforced by bolts 13. An inner support tube 4 is fixed inside the opposing surfaces of the sleeve connector 1. Square tubes A and B are fitted onto the outside of the inner support tube 4. The outer surface of one end of square tubes A and B contacts the inner surface of the sleeve connector 1, and the inner surface of one end of square tubes A and B contacts the outer surface of the inner support tube 4, increasing the support points for square tubes A and B. Through the synergistic action of the sleeve connector 1 and the inner support tube 4, the ends of square tubes A and B are limited, and the contact support points are increased. The pressing assembly includes a pressing rod 11 that slides through the surface of the sleeve connector 1 and a spring plate 14 installed inside the sleeve connector 1. A protrusion 141 is fixed to one end of the spring plate 14. The spring plate 14 is made of a metal material with elasticity and reset function, such as spring steel. The pressing rod 11 applies a pressing force, squeezing the spring plate 14. One end of the spring plate 14 moves without affecting the installation of the extension sleeve 2. The limiting frame 3 is installed on the opposite surface of the sleeve connector 1. The limiting frame 3 has a reinforcing bolt 32 passing through it. The outer surface of the limiting frame 3 is provided with a reinforcing plate 31. Square tubes A and B pass through the limiting frame 3. Under the reinforcement of the reinforcing bolt 32, the limiting frame 3 further limits the square tubes A and B. The reinforcing plate 31 supports the extension sleeve 2 and prevents the extension sleeve 2 from deforming under force. The extension sleeve 2 is sleeved on the outside of the limiting frame 3. The inner side wall of the extension sleeve 2 is provided with opposing first locking blocks 21 and opposing second locking blocks 22. Square tubes A and B pass through the corresponding extension sleeves 2. The extension sleeve 2 is sleeved on the outside of the limiting frame 3. The first locking block 21 and the opposing second locking block 22 are inserted between the opposing reinforcing plates 31. The extension sleeve 2 and the limiting frame 3 are stably connected.

[0028] In this embodiment, one end of the spring plate 14 located inside the sleeve connector 1 is a "U"-shaped hook. One end of the pressing rod 11 inserted into the sleeve connector 1 is fixedly connected to the spring plate 14. The protrusion 141 is a triangular prism structure. A pressing force is applied to the pressing rod 11, and the pressing rod 11 squeezes the spring plate 14. One end of the spring plate 14 moves, and the protrusion 141 moves with the spring plate 14.

[0029] In this embodiment, the spacing between adjacent reinforcing plates 31 on the same side of the surface of the limiting frame 3 is the same as the height of the corresponding first locking block 21 and the width of the second locking block 22. The extension sleeve 2 is sleeved on the outside of the limiting frame 3, and the first locking block 21 and the second locking block 22 are limited by the reinforcing plate 31.

[0030] In this embodiment, the extension sleeve 2 is a cuboid box with one side surface open. A square groove is provided in the center of the sealed side surface of the extension sleeve 2. Square tube A and square tube B pass through the extension sleeve 2. The extension sleeve 2 is fitted on the outside of the limiting frame 3.

[0031] In this embodiment, the surface of the first locking block 21 is provided with a groove 211 that cooperates with the protrusion 141. The protrusion 141 is inserted into the groove 211 to limit the first locking block 21, thereby making the extension sleeve 2 installed stably. It can be further reinforced by screws.

[0032] In this embodiment, a recessed slot is provided on the opposite surface of the sleeve connector 1. The limiting frame 3 is a hollow structure. The internal gap of the limiting frame 3 corresponds to the slot. Square tube A and square tube B pass through the limiting frame 3 and are inserted into the slot. A rubber sleeve 5 is fitted on the outer surface of the inner support tube 4. The rubber sleeve 5 plays a role in absorbing vibration.

[0033] In this embodiment, a sealing sleeve 12 is threadedly connected to the outer surface of the pressing rod 11. The sealing sleeve 12 serves to seal the gap between the pressing rod 11 and the sleeve connector 1.

[0034] Working principle and usage process of this utility model:

[0035] When the steel structure of square tube A and square tube B is connected, square tube A and square tube B pass through the extension sleeve 2 and the limiting frame 3 and are inserted into the slot of the sleeve connector 1.

[0036] The outer surfaces of square tubes A and B are in contact with the inner surfaces of the limiting frame 3 and the sleeve connector 1. The inner surfaces of square tubes A and B are in contact with the rubber sleeve 5 on the outside of the inner support tube 4. This increases the support points of square tubes A and B, increases the contact area between the steel structure building connector and square tubes A and B, reduces the load (stress) per unit area, expands the load transfer area, and avoids excessive local stress that could cause steel deformation or tearing. The rubber sleeve 5 also plays a role in absorbing vibration.

[0037] Square tubes A and B are reinforced by bolted column 13 and reinforcing bolt 32;

[0038] The extension sleeve 2 moves and is fitted onto the outside of the limiting frame 3. The extension sleeve 2 covers the reinforcing bolt 32 to prevent the reinforcing bolt 32 from contacting external moisture molecules and to prevent it from being corroded and rusted.

[0039] As the extension sleeve 2 moves, it applies a pressing force to the pressing rod 11. The pressing rod 11 squeezes the spring plate 14, one end of the spring plate 14 moves, and the protrusion 141 moves with the spring plate 14.

[0040] When the extension sleeve 2 is in contact with the sleeve connector 1, the pressing rod 11 is released, the spring plate 14 is reset, and the protrusion 141 on the spring plate 14 is embedded in the groove 211 to limit the first locking block 21 and thus limit the extension sleeve 2.

[0041] In summary: The steel structure connector of this application has added support points at the ends of the square tube. The square tube passes through the extension sleeve 2 and the limiting frame 3 and is inserted into the interior of the sleeve connector 1. The outer surface of the square tube is in contact with the limiting frame 3 and the sleeve connector 1, and the inner surface of the square tube is in contact with the rubber sleeve 5 on the outside of the inner support tube 4. This increases the contact area and support points of the square tube, increases the contact area between the steel structure connector and the square tube, reduces the load (stress) per unit area, expands the load transfer area, and avoids excessive local stress that could lead to deformation or tearing of the steel.

[0042] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
