Detailed Implementation

[0021] The present application will be further described in detail below with reference to the accompanying drawings.

[0022] This application discloses a steel structure connection node for prefabricated building construction.

[0023] Reference Figure 1 , Figure 2 The steel structure connection node for prefabricated building construction includes a vertically arranged mounting frame 1, with four circumferentially arranged connecting seats 2 welded and fixed to the outer wall of the mounting frame 1. A horizontal beam frame 3 is horizontally installed and fixed to the side of the connecting seat 2 facing away from the mounting frame 1. A limiting clamping plate 20 is integrally formed on the side wall of the connecting seat 2 facing the horizontal beam frame 3, and a clamping groove 21 is provided on the limiting clamping plate 20. A support plate 22 extending below the limiting clamping plate 20 is also integrally formed at the bottom of the connecting seat 2. An insert plate 30 for insertion into the clamping groove 21 from top to bottom is integrally formed on the outer wall of the horizontal beam frame 3 facing the limiting clamping plate 20. The shape of the insert plate 30 matches the shape of the clamping groove 21. The insert plate 30 inserted into the clamping groove 21 is supported on the support plate 22.

[0024] like Figure 1 , Figure 2 As shown, both the limiting clamp plate 20 and the plug-in plate 30 have first mounting holes 31 that are arranged opposite to each other. First fasteners 32 are inserted into the first mounting holes 31 that are arranged opposite to each other. In this embodiment, the first fasteners 32 are bolts and nuts. The limiting clamp plate 20 and the plug-in plate 30 are tightened and fixed by the first fasteners 32.

[0025] like Figure 1 , Figure 2 As shown, both the connecting seat 2 and the crossbeam frame 3 are fixedly equipped with reinforcing plates 33, with adjacent reinforcing plates 33 arranged opposite each other. Multiple second mounting holes 34 are passed through the reinforcing plates 33, and second fasteners 35 are inserted into two oppositely arranged second mounting holes 34. In this embodiment, the second fasteners 35 are bolts and nuts. First fasteners 32 connect and fix the connecting seat 2 and the crossbeam frame 3 together through the reinforcing plates 33.

[0026] When installing the crossbeam frame 3, first insert the plug-in plate 30 into the clamping groove 21 from top to bottom, and then place the plug-in plate 30 on the support plate 22. The interlocking of the plug-in plate 30 and the clamping groove 21 ensures the accuracy of the crossbeam frame 3's installation position, achieving precise positioning. This significantly shortens the adjustment and correction cycle, thereby improving construction efficiency. Next, the limiting clamping plate 20 and the plug-in plate 30 are connected and fixed together using the first fastener 32, thus fixing the crossbeam frame 3 onto the mounting frame 1. Then, the connecting seat 2 and the crossbeam frame 3 are further connected and fixed using the second fastener 35, further enhancing the stability and reliability of the connection between the connecting seat 2 and the crossbeam frame 3.

[0027] like Figure 1 , Figure 2 As shown, a diagonal brace 4 is installed on the outer wall of the mounting frame 1, located below the crossbeam frame 3. The lower end of the diagonal brace 4 is fixed to the outer wall of the mounting frame 1 by bolts, and the upper end of the diagonal brace 4 is inclined upwards. The crossbeam frame 3 is mounted on top of the diagonal brace 4, and a third fastener 40 is installed on the top of the diagonal brace 4. The third fastener 40 includes a threaded post and a nut. The bottom of the threaded post is fixedly installed on the diagonal brace 4, and the threaded post passes through the crossbeam frame 3 from bottom to top, and is then fixed to the crossbeam frame 3 by the nut. The third fastener 40 is used to fix the crossbeam frame 3 to the diagonal brace 4. The diagonal brace 4 can support the crossbeam frame 3, thereby further improving the load-bearing capacity of the crossbeam frame 3.

[0028] like Figure 1 , Figure 2 As shown, a reinforcing seat 5 is provided between the mounting bracket 1 and the connecting seat 2. One side of the reinforcing seat 5 is welded and fixed to the outer side wall of the mounting bracket 1 along the vertical direction, and the bottom of the reinforcing seat 5 is welded and fixed to the upper surface of the connecting seat 2. The reinforcing seat 5 acts as a reinforcing rib, further improving the stability and reliability of the connection between the mounting bracket 1 and the connecting seat 2.

[0029] like Figure 3 , Figure 4As shown, a column 6 is vertically fixed to the top of the mounting bracket 1. A corresponding insertion seat 60, corresponding to the reinforcing base 5 below, is welded to the outer wall of the column 6. The reinforcing base 5 has insertion slots 50 for the respective insertion seats 60 to be inserted from top to bottom into the reinforcing base 5. The shape of the insertion seat 60 matches the shape of the insertion slot 50. A fourth fastener 51 is provided on the reinforcing base 5 to tighten and fix the insertion seats 60 within the reinforcing base 5. The fourth fastener 51 includes a bolt and a nut. The bolt passes sequentially through the reinforcing base 5 and the insertion seat 60, and is then tightened and fixed by the nut.

[0030] When installing the column 6, first insert the connector 60 into the reinforcing base 5 from top to bottom, aligning it with the connector slot 50. Through the interlocking of the connector 60 and the connector slot 50, the column 6 can be accurately installed on the top of the mounting frame 1. At this point, the column 6 will be initially fixed and secured to the mounting frame 1. Finally, the fourth fastener 51 is used to fix the column 6 to the mounting frame 1 and the connecting base 2, thereby ensuring the reliability of the column 6 after installation.

[0031] like Figure 3 , Figure 4 As shown, a splicing plate 10 is welded and fixed to the inner top wall of the mounting frame 1. Multiple positioning holes 11 are drilled through the splicing plate 10. Insertion rods 61, each inserted into its corresponding positioning hole 11, are welded and fixed to the bottom of the column 6. The diameter of the insertion rods 61 matches the diameter of the positioning holes 11. The mutual insertion and engagement of the insertion rods 61 and the positioning holes 11 further enhances the stability of the connection between the column 6 and the mounting frame 1.

[0032] like Figure 1 As shown, a horizontally arranged mounting plate 12 is welded and fixed to the bottom of the mounting frame 1. The mounting plate 12 has multiple circumferentially arranged third mounting holes 13, which are used for anchor rods to pass through. The mounting frame 1 is fixedly installed on the construction surface by the anchor rods.

[0033] The implementation principle is as follows: When installing the crossbeam frame 3, the plug-in plate 30 is first inserted into the clamping groove 21 from top to bottom, and then the plug-in plate 30 is placed on the support plate 22. Through the mutual plugging and engagement of the plug-in plate 30 and the clamping groove 21, the accuracy of the crossbeam frame 3's installation position is ensured, achieving precise positioning of the crossbeam frame 3. This greatly shortens the adjustment and correction cycle, thereby improving construction efficiency. Next, the limiting clamping plate 20 and the plug-in plate 30 are connected and fixed together using the first fastener 32, thus fixing the crossbeam frame 3 onto the mounting frame 1. Then, the connecting seat 2 and the crossbeam frame 3 are further connected and fixed using the second fastener 35, thereby further enhancing the stability and reliability of the connection between the connecting seat 2 and the crossbeam frame 3.

[0034] When installing the column 6, first insert the connector 60 into the reinforcing base 5 from top to bottom, aligning it with the connector slot 50. Through the interlocking of the connector 60 and the connector slot 50, the column 6 can be accurately installed on the top of the mounting frame 1. At this point, the column 6 will be initially fixed and secured to the mounting frame 1. Finally, the fourth fastener 51 is used to fix the column 6 to the mounting frame 1 and the connecting base 2, thereby ensuring the reliability of the column 6 after installation.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
