Description

Technical Field

[0001] This utility model relates to the field of building steel structure technology, specifically to a fast-assembly energy-saving steel structure. Background Technology

[0002] In the field of modern construction, steel structures are widely used in projects such as industrial plants, high-rise residential buildings and long-span bridges due to their advantages such as high strength, light weight and recyclability. However, existing steel structures still have many problems in practical applications. The installation process of traditional steel structures usually requires a lot of on-site welding and bolt tightening work, which not only has low construction efficiency and consumes a lot of manpower and time costs, but also poses safety hazards due to the high temperature and sparks generated by on-site welding, which requires a high level of technical skills from construction personnel and reduces the overall construction progress.

[0003] In view of the above, this application is hereby submitted. Utility Model Content

[0004] The purpose of this utility model is to provide a fast-assembly energy-saving steel structure to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides a quick-assembly energy-saving steel structure, including two interlocking steel profiles, a locking sleeve is fitted at the joint of the two steel profiles, a plate is installed on the locking sleeve, a locking block is installed on the bottom surface of the plate, a slot is opened on the steel profile for the locking block to be inserted, a positioning rod is installed on the plate, a positioning bolt is connected to the bottom end of the positioning rod, and the positioning bolt is threaded to the locking sleeve.

[0006] Furthermore, the card block has an internal receiving groove, and the positioning rod is rotatably mounted on the outer wall inside the receiving groove. A connecting rod is rotatably connected to the rotating sleeve, and a pin is rotatably connected to the other end of the connecting rod. The inner wall of the card groove is provided with a card hole for the pin to be engaged.

[0007] Furthermore, the card block has a sliding opening that connects to the receiving groove, and the pin is slidably connected inside the sliding opening.

[0008] Furthermore, multiple positioning rods are provided, and the multiple positioning rods are distributed in a rectangular array on the plate.

[0009] Furthermore, the bottom surface of the lock sleeve is provided with a threaded through hole, and the positioning bolt is threadedly connected inside the threaded through hole.

[0010] Furthermore, the inner wall of the threaded through hole is provided with an internal thread, and the outer wall of the positioning bolt is provided with an external thread that matches the internal thread.

[0011] Furthermore, an annular groove is formed on the outer wall of the positioning rod, and the rotating sleeve is rotatably connected inside the annular groove.

[0012] Furthermore, the top surface of the lock sleeve is provided with an embedding groove, and the flat plate is installed inside the embedding groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this utility model, after two steel profiles are joined together, a locking sleeve is fitted onto the joint. The flat plate is inserted into the slot of the steel profile through the bottom card block to complete the initial positioning. The positioning rod on the flat plate is rotated, which drives the bottom positioning bolt to be threaded into the threaded through hole of the locking sleeve. The bolt tightening force makes the flat plate press the locking sleeve to fix the steel profile. This achieves plug-and-lock, and the installation time is shortened compared with the traditional process.

[0015] 2. In this utility model, when the positioning rod rotates, its outer wall rotates within the receiving groove, and the connecting rod pushes the pin to slide along the sliding opening, eventually locking into the locking hole of the slot, forming a double locking structure of the locking block and the pin, which enhances the connection stability and fatigue resistance, makes the structure perform well under dynamic loads, reduces assembly errors, and ensures better construction quality, while also being efficient, safe, and stable.

[0021] 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.

[0022] Please see Figures 1-4 This utility model provides a technical solution: a quick-assembly energy-saving steel structure, including two interlocking steel profiles 1, a locking sleeve 2 is fitted at the joint of the two steel profiles 1, a flat plate 3 is installed on the locking sleeve 2, a locking block 7 is installed on the bottom surface of the flat plate 3, a slot 5 is opened on the steel profile 1 for the locking block 7 to be inserted, a positioning rod 4 is installed on the flat plate 3, and a positioning bolt 8 is connected to the bottom end of the positioning rod 4, and the positioning bolt 8 is threadedly connected to the locking sleeve 2.

[0023] Specifically, after the two steel profiles 1 are joined, the locking sleeve 2 is fitted onto the joint, forming a preliminary limit by wrapping the joint of the steel profiles 1. The locking block 7 on the bottom of the flat plate 3 is inserted into the slot 5 of the steel profile 1, realizing the initial locking and positioning of the flat plate 3 and the steel profile 1. The bottom end of the positioning rod 4 on the flat plate 3 is connected to the positioning bolt 8. By rotating the positioning bolt 8, it is threaded onto the locking sleeve 2. The tightening force of the bolt is used to pull the positioning rod 4, so that the flat plate 3 presses the locking sleeve 2, thereby firmly fixing the two steel profiles 1. No on-site welding is required. The quick installation is achieved through the locking of the locking block 7 and the slot 5 and the threaded connection of the positioning bolt 8, which greatly shortens the construction time.

[0024] As a technical optimization of this utility model, the card block 7 has an internal receiving groove 10. The positioning rod 4 is rotatably mounted on the outer wall inside the receiving groove 10 with a rotating sleeve 11. A connecting rod 12 is rotatably connected to the rotating sleeve 11. The other end of the connecting rod 12 is rotatably connected to a pin 14. The inner wall of the card slot 5 is provided with a card hole 6 for the pin 14 to be inserted.

[0025] Specifically, the positioning rod 4 is located in the receiving groove 10 of the locking block 7, and the rotating sleeve 11 is sleeved on the outer wall of the positioning rod 4 and can rotate. When the positioning rod 4 rotates, it drives the rotating sleeve 11 to rotate. The rotating sleeve 11 is connected to the pin 14 through the connecting rod 12. When the rotating sleeve 11 rotates, the connecting rod 12 pushes the pin 14 to slide along the sliding opening 13, and finally makes the pin 14 engage in the locking hole 6 of the locking groove 5, forming a double locking of the locking block 7 and the pin 14. After the pin 14 is engaged in the locking hole 6, it can prevent the lateral displacement between the profile steel 1 and the plate 3. With the longitudinal fastening of the positioning bolt 8, a three-dimensional locking is formed.

[0026] As a technical optimization of this utility model, the card block 7 is provided with a sliding opening 13 that connects to the receiving groove 10, and the pin 14 is slidably connected inside the sliding opening 13.

[0027] Specifically, the sliding opening 13 on the locking block 7 connects to the receiving groove 10, and the pin 14 slides within the sliding opening 13. Its sliding trajectory is defined by the shape of the sliding opening 13, ensuring that the pin 14 can be accurately aligned and inserted into the locking hole 6 under the push of the connecting rod 12. The sliding opening 13 provides a guide for the pin 14, preventing the pin 14 from shifting during movement and ensuring the reliability of the locking action. The design of the sliding opening 13 allows the pin 14 to be finely adjusted within a certain range, adapting to the processing error of the profile steel 1 and improving assembly compatibility.

[0028] As a technical optimization of this utility model, multiple positioning rods 4 are provided, and the multiple positioning rods 4 are distributed in a rectangular array on the plate 3.

[0029] Specifically, multiple positioning rods 4 are arranged in a rectangular array on the plate 3. Each positioning rod 4 is connected to the locking sleeve 2 by a positioning bolt 8, forming a fastening structure with multiple points of uniform force, thus avoiding local deformation caused by excessive force at a single point.

[0030] As a technical optimization of this utility model, the bottom surface of the lock sleeve 2 is provided with a threaded through hole 9, and the positioning bolt 8 is threadedly connected inside the threaded through hole 9.

[0031] Specifically, the inner wall of the threaded through hole 9 on the bottom surface of the lock sleeve 2 is provided with an internal thread, and the external thread on the outer wall of the positioning bolt 8 engages with the internal thread. When the positioning bolt 8 is rotated, the rotational force is converted into axial tension by utilizing the helix angle of the thread, so that the plate 3 presses the lock sleeve 2 tightly.

[0032] As a technical optimization of this utility model, the inner wall of the threaded through hole 9 is provided with an internal thread, and the outer wall of the positioning bolt 8 is provided with an external thread that matches the internal thread.

[0033] Specifically, the annular groove on the outer wall of the positioning rod 4 provides rotation space for the rotating sleeve 11, which can rotate freely in the annular groove while maintaining coaxiality with the positioning rod 4, ensuring that the action of the connecting rod 12 pushing the pin 14 is not interfered with by the rotation of the positioning rod 4.

[0034] As a technical optimization of this utility model, an annular groove is provided on the outer wall of the positioning rod 4, and the rotating sleeve 11 is rotatably connected inside the annular groove.

[0035] As a technical optimization of this utility model, the top surface of the lock sleeve 2 is provided with an embedding groove, and the flat plate 3 is installed in the embedding groove.

[0036] Specifically, the embedding groove on the top surface of the lock sleeve 2 provides an installation groove for the plate 3. After the plate 3 is embedded in the groove, the groove wall can restrict the horizontal displacement of the plate 3, ensuring that the relative position of the plate 3 and the lock sleeve 2 is accurate, which facilitates the alignment of the locking block 7 and the locking groove 5.

[0037] Working principle: After the two steel profiles 1 are joined together, the locking sleeve 2 is fitted onto the joint. The plate 3 is inserted into the slot 5 of the steel profile 1 through the bottom locking block 7 to complete the initial positioning. The positioning rod 4 on the plate 3 is rotated, which drives the bottom positioning bolt 8 to be threaded to the threaded through hole 9 of the locking sleeve 2. The bolt tightening force makes the plate 3 press the locking sleeve 2, thus achieving the initial fixation of the steel profile 1.

[0038] When the positioning rod 4 rotates, its outer wall rotating sleeve 11 rotates in the receiving groove 10, and pushes the pin 14 to slide along the sliding opening 13 through the connecting rod 12, and finally gets into the locking hole 6 of the locking groove 5, forming a double locking structure of the locking block 7 and the pin 14. Multiple positioning rods 4 are distributed in a rectangular array, which, together with the locking sleeve 2, embeds into the groove on the top surface to limit the plate 3, ensuring that the load at the docking point is evenly distributed and improving the overall structure.
