[0039] like Figure 1-8 As shown, a keel connection device for building steel structure in this embodiment includes a connection body 1, which is composed of two connecting frames 11 arranged in a front-to-back cross pattern. The connecting frames 11 are provided with a connecting channel 12, which is used to install the keel 3. The two connecting frames 11 are rotatably connected by an adjustment mechanism 2.

[0040] The adjustment mechanism 2 includes a pin 21, a first locking component 22, and a second locking component 23. The pin 21 is parallel to the front-back direction. Blind holes 24 are provided on the sides of the two connecting frames 11 that are close to each other. The two ends of the pin 21 are respectively inserted into the blind holes 24. The diameter of the pin 21 is equal to the diameter of the blind hole 24. The first locking component 22 and the second locking component 23 are both used for locking between the two connecting frames 11.

[0041] The first locking assembly 22 includes an arc-shaped strip 22.1, which is fixedly mounted on the front connecting frame 11 and is coaxially mounted with the pin 21. A connecting block 22.2 is fixedly mounted on the rear connecting frame 11. The connecting block 22.2 is provided with a sliding groove 22.3 that matches the arc-shaped strip 22.1. The arc-shaped strip 22.1 passes through the sliding groove 22.3. The connecting block 22.2 is locked to the arc-shaped strip 22.1 by a first screw 22.4.

[0042] Two locking components 22 are provided, and the two locking components are arranged symmetrically about the pin 21.

[0043] The second locking assembly 23 includes two second locking units 23.1, which are arranged in a cross pattern;

[0044] The second locking unit 23.1 includes a locking screw 23.11 and two locking pins 23.12. The two locking pins 23.12 are symmetrically arranged about the pin 21. The locking pins 23.12 abut against the outer walls of the two connecting frames 11 respectively. The locking screw 23.11 passes through the two locking pins 23.12 in sequence. Two locking nuts 23.13 are threaded onto the locking screw 23.11. The two locking pins 23.12 are located between the two locking nuts 23.13. The two locking nuts 23.13 abut against the two locking pins 23.12 respectively.

[0045] There are two locking screws 23.11 in the same second locking unit 23.1, and the two locking screws 23.11 are respectively located on the front and rear sides of the connecting body 1;

[0046] The connecting frame 11 includes two frame bodies 11.1, which are arranged symmetrically front and back. Each of the two frame bodies 11.1 has a mounting groove 11.2 on the side that is close to each other. The two mounting grooves 11.2 form a connecting channel 12. The two frame bodies 11.1 are detachably fixedly connected by bolts 11.3.

[0047] The connecting frame 11 is provided with two first pads 11.4. Both first pads 11.4 are inside the connecting channel 12. The two first pads 11.4 correspond one-to-one with the two frame bodies 11.1 respectively. The two first pads 11.4 are arranged symmetrically front and back.

[0048] The first pad 11.4 is composed of a plurality of first pads 11.41, which are arranged in sequence from front to back;

[0049] The connecting frame 11 is also provided with two tightening screws 11.5. The two tightening screws 11.5 are symmetrically arranged along the width direction of the connecting channel 12. The tightening screws 11.5 are threadedly connected to the connecting frame 11. The two tightening screws 11.5 are used to lock the keel 3 in the width direction.

[0050] Two second pads 11.6 are provided in the connecting channel 12, and the two second pads 11.6 correspond one-to-one with two tightening screws 11.5. The two second pads 11.6 are located between the two tightening screws 11.5. A spring 11.7 is provided on the side of the two second pads 11.6 that are far apart from each other. The spring 11.7 and the second pad 11.6 are both located in the connecting channel 12. The second pad 11.6 is connected to the inner side wall of the connecting channel 12 through the spring 11.7. The tightening screws 11.5 abut against the second pads 11.6.

[0051] Working principle:

[0052] Loosen bolt 11.3 to separate the two frame bodies 11.1. When the two frame bodies 11.1 are combined to form the connecting frame 11, they can be fixed by bolt 11.3.

[0053] During the fixing of the keel 3, the two keels 3 are respectively passed through the two connecting channels 12, and the two first pads 11.4 in the same connecting channel 12 are respectively attached to the front and rear sides of the keel 3. By rotating the tightening screw 11.5, the two second pads 11.6 in the same connecting channel 12 are pushed to be attached to the two sides of the keel 3 in the width direction, and the spring 11.7 is deformed. In addition, by adjusting the number of first pads 11.41, the distance between the two keels 3 can be adjusted. The attachment of the second pads 11.6 to the keel 3 can prevent the tightening screw 11.5 from directly contacting the keel 3, thereby preventing the tightening screw 11.5 from putting excessive local pressure on the keel 3 and causing damage to the keel 3. By adjusting the distance by which the tightening screw 11.5 pushes the second pads 11.6, it can be used for keels 3 of different widths.

[0054] When disassembling the keel 3, rotate the tightening screw 11.5 in the opposite direction, and the second washer will move away from the keel 3 and separate from the keel 3 due to the elastic action of the spring 11.7. Then, loosen the bolt 11.3 and pull the keel 3 out of the connecting channel 12.

[0055] When adjusting the angle between the two keels 3, loosen the first screw 22.4 to tighten the locking nut 23.13, so that both connecting frames 11 can rotate around the pin 21. At the same time, the arc groove moves within the slide groove 22.3, thus achieving the adjustment of the angle between the two keels 3. After the angle is adjusted, tighten the first screw 22.4 to achieve the first locking between the two connecting frames 11. Then, tighten the locking nut 23.13 so that the locking pin 23.12 abuts against the two connecting frames 11 respectively, thus achieving the second locking of the connecting frames 11, thereby improving the stability of the connection between the two connecting frames 11.

[0056] In addition, when disassembling the keel 3, the keel 3 can be removed after removing one side of the frame 11.1, without having to pull out the keel 3, which facilitates the disassembly of the keel 3.

[0057] In summary, by adjusting the angle between the two connecting frames 11, the angle between the two keels 3 can be adjusted. By adjusting the number of the first shims 11.41, the distance between the two keels 3 can be adjusted, thus expanding the applicable range. Moreover, the connecting frame 11 is made of two frame bodies 11.1 spliced ​​together. When disassembling the keel 3, the keel 3 can be removed after removing one side of the frame body 11.1, without having to pull out the keel 3, which facilitates the disassembly of the keel 3.

[0058] In addition to the above embodiments, the present invention also includes other embodiments. All technical solutions formed by equivalent transformation or equivalent substitution should fall within the protection scope of the claims of the present invention.
