After welding, cooling, slag removal, and anti-rust paint are required. The construction time is long and the construction efficiency is low.

[0003] In addition, it is difficult to control the quality of the welds during the steel frame welding construction, and welding stress is easily formed on the dome position structure, causing the dome structure to have a reduced stress stability and resulting in safety problems. Utility Model Content

[0004] The purpose of the utility model is to provide an assembled base steel frame connection structure based on mechanical connection, so as to solve the problem of low structural safety caused by welding connection of the base steel frame.

[0007] The second square tube has a buckling plate provided on one opposite side wall of its end portion, the buckling plate being used to buckle with the notch;

[0008] A socket connector, which is sleeved on the connection between the first square tube and the second square tube;

[0009] A first U-shaped fastening member, having a first connecting plate on one side and an outer bending plate on the other opposite side;

[0010] The second U-shaped fastening component has a second connecting plate on one side and an inner bending plate on the other side. The outer bending plate is buckled with the inner bending plate, and the second connecting plate is fixedly mounted on the first connecting plate by a bolt connector.

[0015] As a further description of the above technical solution:

[0016] The length of the first U-shaped fastening member is greater than or equal to the length of the sleeve.

[0017] As a further description of the above technical solution:

[0018] A reinforcing rod is arranged between the two buckling plates.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0020] 1. In the present invention, the bottom of the base steel frame is fixed to the original building by high-strength bolts. When two stainless steel square tubes on the base steel frame are connected, they are connected to each other in a mortise and tenon manner by fastening the end plates and notches of the two. Then, the socket is put on the connection, and then the two first U-shaped fastening members are fastened by the outer bending plate and the inner bending plate, and preliminarily fixed by the bolt connector. After sliding and adjusting the position to the socket, the bolt connector is locked to complete the detachable mechanical connection. The mechanical connection replaces the original welding connection method, solves the welding stress caused by the difficulty in controlling the construction quality of the welding weld, and greatly improves the stress stability of the structure. It provides a reliable transmission path for the load-bearing of decorative materials such as GRG arranged on the base steel frame, ensuring the safety and stability of the hoisted decorative materials and the base steel frame itself.

[0021] 2. In the present invention, the base steel frame does not need to be reinforced, which simplifies the use of steel in the local reinforcement area of ​​the base steel frame, thereby greatly reducing the weight of the base steel frame itself, meeting the requirements of hoisting decorative materials, and increasing structural safety.

[0022] 3. In the present invention, mechanical connection is used instead of the original welding connection, which eliminates the need for open flame welding at the construction site and eliminates some safety hazards. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Example 1

[0032] See also Figure 1-4 The utility model provides a technical solution: an assembled base steel frame connection structure based on mechanical connection, comprising:

[0033] The first square tube 1 has a notch 11 formed on one of the opposite side walls of the end portion;

[0034] The second square tube 2 has a buckling plate 21 provided on one opposite side wall of its end portion, and the buckling plate 21 is used to buckle with the notch 11;

[0035] A socket 3 is sleeved on the connection between the first square tube 1 and the second square tube 2;

The outer bending plate 42 is buckled with the inner bending plate, and the second connecting plate 51 is fixedly installed on the first connecting plate 41 by a bolt connector 6.

[0038] The base steel frame does not need to be reinforced, which simplifies the use of steel in the local reinforcement area of ​​the base steel frame, thereby greatly reducing the weight of the base steel frame itself, meeting the needs of lifting decorative materials, and increasing structural safety.

[0039] At the same time, mechanical connections are used instead of the original welding connections, eliminating open flame welding operations at the construction site and eliminating some safety hazards.

[0040] The second connecting plate 51 is provided with three bolt connectors 6 arranged along a straight line, which effectively ensures the connection strength.

[0041] The length of the first U-shaped fastening member 4 is greater than or equal to the length of the socket 3, which effectively ensures the connection strength.

[0042] The first square tube 1 is a stainless steel tube, and the second square tube 2 is a stainless steel tube.

[0043] The sleeve 3 is a flexible sleeve, and specifically can be a rubber tube.

[0044] Working principle: The bottom of the base steel frame is fixed to the original building by high-strength bolts. When the two stainless steel square tubes on the base steel frame are connected, the mortise and tenon method is realized by fastening the end plates 21 and the notches 11 of the two. Then the socket 3 is put on the connection, and then the two first U-shaped fastening members 4 are fastened by the outer bending plate 42 and the inner bending plate, and preliminarily fixed by the bolt connector 6. After sliding and adjusting the position to the socket 3, the bolt connector 6 is locked to complete the detachable mechanical connection. The mechanical connection replaces the original welding connection method, solves the welding stress caused by the difficulty in controlling the construction quality of the welding weld, and greatly improves the stress stability of the structure. It provides a reliable transmission path for the load-bearing of decorative materials such as GRG arranged on the base steel frame, ensuring the safety and stability of the hoisted decorative materials and the base steel frame itself.

[0045] Example 2

[0046] Based on the above embodiment, this embodiment further makes the following improved technical solutions: a rubber pad 7 is provided between the first connecting plate 41 and the second connecting plate 51, so that the first connecting plate 41 and the second connecting plate 51 fit together, ensuring the locking effect and further improving the connection strength.

[0048] This embodiment further provides the following improved technical solution based on the above embodiment: a reinforcing rod 8 is provided between the two buckling plates 21 , and the end of the reinforcing rod 8 is inserted into the blind hole on the buckling plate 21 .

[0049] The reinforcing rod 8 effectively prevents the buckling plate 21 from bending and deforming, and effectively ensures the connection strength of the mortise and tenon connection between the stainless steel square tubes. At the same time, the reinforcing rod 8 is detachable, which is convenient for disassembly and replacement of rods of different sizes.
