[0002] Prefabricated steel structure frames often adopt a multi-module combination connection method to form frame module units. Therefore, connecting parts are generally required to tighten between adjacent prefabricated steel structure frames to ensure the firmness of the connection.

[0003] For example, in the patent document with patent publication number CN203866977U, a connecting component and a combined frame are disclosed, whose main structure includes a fixing plate and a connecting plate, the fixing plate has a first fastening plate and a second fastening plate, and the connecting plate and the second fastening plate are both provided with a fixing portion; one end of the first fastening plate is connected to one end of the second fastening plate, the first fastening plate and the second fastening plate have an angle, and the connecting plate is matched and connected with the first fastening plate.

[0004] From the above, it can be seen that the connecting component mainly cooperates with the first frame bar and the second frame bar through the first fastening plate, the second fastening plate and the connecting plate when connecting and positioning adjacent frames; however, in actual use, the connection points only rely on the connecting plates to bear the weight, and the overall load-bearing effect and positioning and locking effect are poor.

[0012] In any of the above solutions, it is preferred that the upper first beam body and the lower second beam body are components on two different steel structure frames that are adjacent to each other.

[0013] In any of the above solutions, preferably, each of the first nuts and each of the second nuts are anti-slip nuts.

Figure 1-Figure 7 As shown in .

[0030] Example 1: A prefabricated and assembled steel structure frame fastening connection component, comprising two H-shaped connecting seats 1 arranged at intervals, the upper U-shaped cavity 2 of each H-shaped connecting seat 1 being respectively clamped on the bottom of the first beam 3 of the steel structure frame located above it, and the lower U-shaped cavity 4 of each H-shaped connecting seat 1 being respectively clamped on the top of the second beam 5 of the steel structure frame located below it, and each H-shaped connecting seat 1 being respectively fixedly connected to the first beam 3 of the steel structure frame and the second beam 5 of the steel structure frame at the corresponding position, and a linkage anti-detachment component is respectively provided on both sides of the two H-shaped connecting seats 1, and the middle part of each linkage anti-detachment component is fixedly connected to the first beam 3 of the steel structure frame and the second beam 5 of the steel structure frame at the corresponding position. The prefabricated and assembled steel structure frame fastening connection component in the present invention adopts two H-shaped connecting seats 1 as a whole to complete the restraint and limitation function of the upper and lower adjacent steel structure frames, and relies on the connecting parts to complete the fixation and fastening of the two. In order to ensure the anti-slip effect of the connection when used under vibration conditions, the linkage anti-slip components on both sides are used to form an overall linkage anti-slip fastening, which enhances the anti-slip effect of each nut at the connection parts on both sides. At the same time, the connection in the middle can enhance the fixing effect of the entire linkage anti-slip component and the second beam body 5 and the first beam body 3, thereby achieving the purpose of completing multi-point fixation and fastening of the entire component to the second beam body 5 and the first beam body 3.

[0031] In any of the above schemes, it is preferred that a horizontally arranged first stud 6 is respectively provided in each of the upper U-shaped cavities 2, and both ends of the first stud 6 respectively pass through the first beam 3 at the corresponding position and pass out to both sides of the H-shaped connecting seat 1, and first nuts 7 are respectively screwed on the external thread sections of the outer walls at both ends of the first stud 6, and the inner end faces of each of the first nuts 7 respectively abut against the corresponding side walls of the H-shaped connecting seat 1.

[0032] The horizontally arranged first stud 6 adopts a double-headed stud structure, and its two ends pass through the two sides of the H-shaped connecting seat 1. The first nut 7 at the end can be used to fasten the upper part of the entire H-shaped connecting seat 1 and the corresponding first beam body 3, thereby ensuring the stability of the entire structural connection.

[0033] In any of the above schemes, it is preferred that a horizontally arranged second stud 8 is respectively provided in each of the lower U-shaped cavities 4, and both ends of the second stud 8 respectively pass through the first beam body 3 at the corresponding position and pass out to both sides of the H-shaped connecting seat 1, and second nuts 9 are respectively screwed on the external thread sections of the outer walls at both ends of the second stud 8, and the inner end faces of each second nut 9 respectively abut against the corresponding side walls of the H-shaped connecting seat 1.

[0034] The horizontally arranged second stud 8 adopts a double-headed stud structure, and its two ends pass through the two sides of the H-shaped connecting seat 1. The second nut 9 at the end can be used to fasten the lower part of the entire H-shaped connecting seat 1 and the corresponding second beam body 5, thereby ensuring the stability of the entire structural connection.

[0035] By using a plurality of first studs 6 and a plurality of second studs 8 in combination, the fastening effect of each H-shaped connecting seat 1 can be enhanced, so as to achieve the effect of quickly controlling the firm connection between the first beam 3 of the upper steel structure frame and the second beam 5 of the lower steel structure frame, thereby ensuring the firmness of the connection of the beams at the adjacent docking parts of the two steel structure frames.

[0036] In any of the above schemes, it is preferred that the linkage anti-slip assembly includes a horizontally arranged I-shaped connecting plate 10, and a polyhedral cavity 11 is respectively provided at the four corners of the I-shaped connecting plate 10, and each polyhedral cavity 11 is used to cooperate with the outer wall of the first nut 7 or the outer wall of the second nut 9 at the corresponding position.

[0037] When the linkage anti-slip assembly designed in the utility model is installed, it can rely on the multi-prism cavity 11 designed at the four corners of the I-shaped connecting plate 10 on the corresponding side to complete the external locking of the first nut 7 and the second nut 9 at the corresponding position. Since the entire I-shaped connecting plate 10 tightens multiple nuts, it can prevent each nut from slipping off and rotating.

[0038] Example 2: Compared with Example 1, this example also includes the following technical features:

[0039] In any of the above schemes, it is preferred that connecting holes 12 are respectively provided at the upper and lower ends of the middle vertical section of each I-shaped connecting plate 10, and connecting studs 13 are respectively provided between the two connecting holes 12 coaxially arranged on both sides of the second beam body 5 or the first beam body 3, and the two ends of each connecting stud 13 are respectively movable through the second beam body 5 or the first beam body 3 at the corresponding position and extend to the outside of the I-shaped connecting plate 10, and the external thread sections of the outer side walls of the two end portions of each connecting stud 13 are respectively screwed and installed with anti-loosening nuts 14, and the inner ends of each anti-loosening nuts 14 respectively abut against the outer side walls of the I-shaped connecting plate 10 at the corresponding positions.

[0040] Taking into account the firmness of the I-shaped connecting plate 10 itself, which is used as an anti-slip part to control the first nuts 7 and the second nuts 9, the connecting studs 13 and the anti-loosening nuts 14 located at both ends of the connecting studs 13 are also used here to complete the clamping and positioning of the outer wall of the I-shaped connecting plate 10 in the middle, thereby ensuring the central positioning of the entire I-shaped connecting plate 10, and then achieving the effect of controlling the entire I-shaped connecting plate 10 to clamp and prevent the nuts at the four corners from slipping off.

[0041] In any of the above solutions, it is preferred that the inner side wall of each of the I-shaped connecting plates 10 abuts against the outer side wall of the H-shaped connecting seat 1 at the corresponding position.

[0042] The design of the inner side wall of the I-shaped connecting plate 10 pressing against the I-shaped connecting plate 10 can ensure a tight pressing effect when the two are clamped and positioned.

[0043] In any of the above solutions, it is preferred that the upper first beam 3 and the lower second beam 5 are components on two different steel structure frames that are adjacent to each other.

[0044] It should be noted that when multiple prefabricated and assembled steel structure frames are connected, this component can also be installed between two adjacent butt-jointed beams as needed to complete the fastening assembly of the beams at the corresponding positions and ensure the firmness of the entire connection part; the specific number of installations of this component is determined and selected according to the size of the current frame.

[0045] In any of the above solutions, it is preferred that each of the first nuts 7 and each of the second nuts 9 are anti-slip nuts.

[0046] It should be noted that each I-shaped connecting plate 10 plays the role of controlling the first nuts 7 and the second nuts 9 on the corresponding side to prevent them from falling off, and effectively completes the anti-rotation of the four nuts on the corresponding side through the single component of the I-shaped connecting plate 10; in addition, since each of the first nuts 7 and the second nuts 9 adopts anti-falling nuts, a secondary anti-falling structure can be formed at both ends of each first stud 6 and both ends of the second stud 8, effectively ensuring that the tightening effect of the connection parts of the two different adjacent steel structure frames is achieved under the action of this connection component.

[0047] The thickness of each I-shaped connecting plate 10 in this assembly is 3-5 mm, and the wall thickness of the H-shaped connecting seat is 3-5 mm.

[0048] Among them, each I-shaped connecting plate 10 and H-shaped connecting seat are made of high carbon steel.

[0049] Specific working principle: The prefabricated assembled steel structure frame fastening connection component in the present invention adopts two H-shaped connecting seats 1 as a whole to complete the restraint and limitation function of the upper and lower adjacent steel structure frames.

[0050] When connecting, the two are fixed and fastened by means of studs and nut connectors.

[0051] In order to ensure the anti-detachment effect of the connection when used under vibration conditions, the linkage anti-detachment components on both sides are used to form an overall linkage anti-detachment and overall fastening.

[0052] The structural design of the linkage anti-slipping component can enhance the anti-slipping effect of each nut at the connection parts on both sides, and the middle connection can enhance the fixing effect of the entire linkage anti-slipping component and the second beam body 5 and the first beam body 3, thereby achieving the purpose of multi-point fixation and fastening of the entire component to the second beam body 5 and the first beam body 3.

[0053] In summary, it can be seen that the prefabricated and assembled steel structure frame fastening connection component of this design can realize the fastening connection of the first beam 3 and the second beam 5 of the adjacent parts of the two upper and lower adjacent prefabricated and assembled steel structure frames, ensuring the firmness of the connection parts, and at the same time can be suitable for fastening and anti-slipping under vibration conditions, ensuring the fastening effect of the mobile modular prefabricated and assembled steel structure frame used in a vibration environment; this fastening connection component relies on the H-shaped connecting seat 1 set at adjacent intervals as a constraint, which can realize the control of the second beam 5 on the upper part and the first beam 3 on the lower part to form lateral limits on both sides, and then cooperate with the corresponding The tightening effect of the first stud 6, the first nut 7, the second stud 8, and the second nut 9 can effectively ensure the tightening in the upper and lower directions, and ensure the tightening effect of the first beam 3 and the second beam 5 at the adjacent docking parts of the upper and lower parts of the two adjacent steel structure frames; the whole is composed of rigid carbon steel structural parts, which can ensure its overall supporting effect and connection and tightening effect; the installation of corresponding linkage anti-falling components on both sides of the second beam 5 and the first beam 3 can achieve simultaneous control of the anti-falling of each first nut 7 and the second nut 9, effectively enhancing the anti-vibration and anti-falling effect of the entire nut connection part.

[0054] Due to the anti-slip effect of each first nut 7 and second nut 9 itself combined with the anti-slip effect brought by the socket fitting of each multi-prism cavity 11 of the entire I-shaped connecting plate 10, secondary anti-slip can be achieved, thereby improving the vibration anti-slip effect of the entire connection part as a whole.
