They have the advantages of light weight, factory manufacturing, fast installation, short construction period, good earthquake resistance, fast investment recovery, and less environmental pollution.

[0003] H-shaped steel is an economical and efficient profile with a more optimized cross-sectional area distribution and a more reasonable strength-to-weight ratio. It is named because its cross-section is the same as the English letter H. Since all parts of the H-shaped steel are arranged at right angles, H-shaped steel has the advantages of strong bending resistance in all directions, simple construction, cost savings and light structural weight, and has been widely used. H-shaped steel is a new type of economical construction steel. The cross-sectional shape of H-shaped steel is economical and reasonable, with good mechanical properties. During rolling, the extension of each point on the cross-section is relatively uniform and the internal stress is small. Compared with ordinary I-beams, it has the advantages of large section modulus, light weight and metal saving.

The utility model has the advantages of novel structure, ingenious design and convenient use, and can weld multiple positions of the steel member at the same time, improves the working efficiency of the steel member, saves a lot of welding seams and labor costs, improves the bearing capacity, and is conducive to wide promotion.

[0005] This patent has some shortcomings when used, such as: the device in this patent combines and forms components by welding multiple H-shaped steels with fixing plates, but because it is fixed by welding, it is extremely inconvenient to disassemble, which is not conducive to the recycling and utilization of components; in addition, the device in this patent is not convenient for users to adjust H-shaped steels in different directions according to their needs, and it is not convenient to connect with other connecting parts.

[0049] A fixing mechanism, which is located in the storage cavity 15 and is used to fix the connecting member 2 to the base 1;

[0050] A round rod 22, the round rod 22 is rotatably mounted in the round hole 19, and one end of the round rod 22 is connected to the fixing mechanism;

[0051] A limit assembly, which is located at the position of the annular groove 20 and is used to constrain and limit the rotation direction of the round rod 22;

[0052] In this embodiment, the fixing mechanism includes:

[0053] There are two plug blocks 16, which are symmetrically arranged and slidably installed in the storage cavity 15. An elliptical disk 17 coaxially connected to the round rod 22 is arranged between the two plug blocks 16. The two plug blocks 16 and multiple tension springs 18 are symmetrically fixed on the circumferential side of the elliptical disk 17. The vertical plate 13 is provided with a socket 14 that is compatible with the plug block 16, and the plug block 16 is plugged into and matched with the corresponding socket 14.

[0054] In this embodiment, the limiting component includes:

[0055] The annular block 23 is rotatably mounted in the inner cavity of the annular groove 20 and is coaxially connected to the round rod 22. A plurality of chute grooves 21 equidistantly distributed around the circumference of the annular groove 20 are provided on the circumferential wall. A limit block 25 is slidably mounted in the chute 21. A spring 26 is fixed between the limit block 25 and the inner wall of the chute 21. A plurality of limit holes 24 matching the limit blocks 25 are provided on the annular block 23. The limit blocks 25 are plugged into and matched with the limit holes 24.

[0056] In this embodiment, the limiting component also includes:

[0057] The positioning block 27 is fixedly mounted on the outer wall of the base 1. One end of the round rod 22 passes through the side wall of the positioning block 27 and extends to the outside and is fixed with a turntable 30. Two vertically distributed positioning holes 28 are provided on the round rod 22 and located inside the positioning block 27. A through hole is provided on the positioning block 27. A latch 29 is inserted and installed in the through hole on the positioning block 27. One end of the latch 29 passes through the positioning hole 28 and passes out from the through hole on the other side to the outside.

[0058] The operating principle of the device is as follows:

[0059] During installation, the connector 2 is plugged and installed on the top of the base 1. Then the operator holds the turntable 30 and rotates the round rod 22 through the turntable 30, and uses the round rod 22 to drive the fixing mechanism to work. It is worth noting that in the initial state, the two plug blocks 16 in the fixing assembly are retracted in the storage cavity 15 under the tension of multiple tension springs 18, and the elliptical disk 17 is in a vertical placement state. The circumferential wall of the elliptical disk 17 in the present device is always in contact with the inner side walls of the two plug blocks 16. At this time, the multiple tension springs 18 of the elliptical disk 17 are in contact with the inner side walls of the two plug blocks 16. In the natural contraction state, when the fixing assembly works, the oval disk 17 gradually rotates to a horizontal placement state, and the two ends of the oval disk 17 push the plug block 16 outward, and push the plug block 16 from the storage cavity 15 to the outside. In this process, multiple tension springs 18 are gradually stretched, and the outer end of the plug block 16 penetrates into the slot 12 and finally snaps into the inner cavity of the socket 14 on the vertical plate 13, thereby realizing the constraint and fixation of the connector 2. In order to ensure that the oval disk 17 will not be reset by the reverse force generated by the multiple tension springs 18, the limit assembly When the work starts, during the rotation of the round rod 22, the annular block 23 rotates synchronously with the round rod 22. The limiting hole 24 on the annular block 23 gradually disengages from the limiting block 25 in the previous direction during the rotation. When the round rod 22 rotates 90°, the newly matched limiting block 25 falls into the limiting hole 24 and restrains the round rod 22 by cooperating with the limiting hole 24. It is worth adding that the front end of the limiting block 25 is a hemispherical protrusion. When the round rod 22 is not subjected to external force {such as operation In the case where the operator holds the turntable 30 to rotate the round rod 22, the round rod 22 will not rotate naturally under the action of the multiple limit blocks 25. Furthermore, in order to ensure the stability of the round rod 22, the operator needs to pull out the latch 29 from the positioning block 27 before rotating the round rod 22. At this time, the latch 29 is no longer matched with the positioning hole 28. When the rotation of the round rod 22 is completed, the latch 29 can be inserted again. Under the action of the latch 29, even if the round rod 22 is affected by external force, the round rod 22 cannot rotate naturally;

[0060] When the operator chooses to fix the steel structure in different directions according to the needs, the end of the H-shaped steel 7 with the through hole 8 is inserted into the limit frame 5, and then the fixing plate 9 is closed, the block 10 at the edge of the fixing plate 9 is matched with the through hole 8, and the fixing bolt 11 is used to realize the rapid fixation and installation of the H-shaped steel 7. The device is easy to install and easy to adjust and disassemble.

[0061] By setting a fixing mechanism and a limiting assembly, the plug block 16 is used to realize the clamping and fixing of the connecting member 2, so that the connecting member 2 can be stably fixed directly above the base 1, and the round rod 22 is constrained by multiple limiting blocks 25 and latches 29, so as to ensure the stability of multiple plug blocks 16 when working; by setting an H-shaped steel 7, a through hole 8 is opened on the H-shaped steel 7, and the fast disassembly and installation of the H-shaped steel 7 is realized by using the clamping block 10 and the fixing bolt 11 on the fixing plate 9, and the advantages of the H-shaped steel 7 having strong bending resistance and simple structure are utilized to greatly improve the overall strength of the steel structure; by setting a connecting member 2, and opening threaded holes 3 in multiple directions on the connecting member 2, a limiting frame 5 is installed at the position of the threaded hole 3 and the H-shaped steel 7 is plugged and installed by using the limiting frame 5, so that the user can install the H-shaped steel 7 in different directions according to actual needs, thereby avoiding the waste of device parts and raw materials and greatly improving the diversity and convenience.
