Detailed Implementation

[0051] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the disclosure. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present disclosure are shown in the accompanying drawings.

[0052] It should be noted that, where there is no conflict, the embodiments and features described in this disclosure can be combined with each other. This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0053] Example 1

[0054] like Figures 1 to 3 As shown, the prefabricated steel pipe block structure includes a block body 1. One end of the block body 1 has a first upper connecting part 2 and a first lower connecting notch 3, and the opposite end has a second lower connecting part 4 and a second upper connecting notch 5. The first upper connecting part 2 is located above the first lower connecting notch 3, and the second lower connecting part 4 is located below the second upper connecting notch 5. The upper end face of the first upper connecting part 2 is flush with the upper end face of the block body 1, and the lower end face of the second lower connecting part 4 is flush with the lower end face of the block body 1. Both are horizontal planes. The thickness of the first upper connecting part 2 and the second lower connecting part 4 is the same as the thickness of the block body 1.

[0055] The first upper connecting part 2 and the second upper connecting notch 5 are horizontally opposite and matched with each other, and the second lower connecting part 4 and the first lower connecting notch 3 are horizontally opposite and matched with each other;

[0056] A first steel pipe 6 is fixedly installed inside the first upper connecting part 2, and a second steel pipe 7 is fixedly installed inside the second lower connecting part 4. The upper and lower ends of the first steel pipe 6 and the second steel pipe 7 are both open, and the steel pipes are hollow with cavities. The two ends of the first steel pipe 6 pass through the upper and lower end faces of the first upper connecting part 2, and the two ends of the second steel pipe 7 pass through the upper and lower end faces of the second lower connecting part 4. At least one end of the first steel pipe 6 and at least one end of the second steel pipe 7 are used to connect to the first vertical steel pipe connector 8. The first steel pipe 6 and the second steel pipe 7 can be round steel pipes or square steel pipes. In this embodiment, they are specifically square steel pipes.

[0057] The block body 1 is made of ordinary aerated concrete or high-strength ceramsite concrete. Combined with the aforementioned structural design, it is lighter than ordinary density concrete of the same volume and strength grade, making transportation and hoisting more convenient and cost-effective.

[0058] During the production of the block structure, a mold of the corresponding structural size is prepared, the processed first steel pipe 6 and second steel pipe 7 are positioned in the corresponding positions in the mold, and concrete is poured into the mold, compacted, and after preliminary curing, a single block structure is formed.

[0059] Furthermore, the lower end face of the first upper connecting part 2 is a horizontal plane, and the upper end face of the second lower connecting part 4 is a horizontal plane, further ensuring the reliability and convenience of the connection between the two block structures; the heights of the first upper connecting part 2 and the first lower connecting notch 3 are both half the height of the block body 1, and the heights of the second lower connecting part 4 and the second upper connecting notch 5 are both half the height of the block body 1, that is, the heights of the first upper connecting part 2, the first lower connecting notch 3, the second lower connecting part 4, and the second upper connecting notch 5 are all the same, further improving the standardization of the block structure. In the process of connecting the two block structures, the corresponding matching work of the connecting part and the connecting notch is eliminated, that is, the connecting part and the connecting notch can match each other, further improving the construction efficiency.

[0060] like Figure 8 , 9 As shown, the two aforementioned block structures can be connected to form an L-shaped node or a type I node;

[0061] When connected into an L-shaped node: the lower part of the first vertical steel pipe connector 8 is installed to the upper part of the second steel pipe 7 of the second block structure, and then the lower part of the first steel pipe 6 of the first block structure is installed from top to bottom to the upper part of the first vertical steel pipe connector 8. At this time, the two block structures are perpendicular, the first upper connection part 2 of the first block structure is located above the second lower connection part 4 of the second block structure and matches the second upper connection notch 5 of the second block structure. The connection process is convenient and quick.

[0062] When connected into a type 1 node: the lower part of the first vertical steel pipe connector 8 is installed to the upper part of the second steel pipe 7 of the second block structure, and then the lower part of the first steel pipe 6 of the first block structure is installed from top to bottom to the upper part of the first vertical steel pipe connector 8. At this time, the two block structures are parallel, the first upper connection part 2 of the first block structure is located above the second lower connection part 4 of the second block structure, and matches the second upper connection notch 5 of the second block structure. The connection process is convenient and quick.

[0063] When overlapping installation is required in the height direction, the upper block structure and the lower block structure are still connected by the first vertical steel pipe connector 8. The cavities of the steel pipes stacked sequentially in the height direction are interconnected, and concrete can be poured into the steel pipes to further strengthen the entire building structure.

[0064] Example 2

[0065] like Figure 2 , 3 As shown, based on Embodiment 1, a first positioning connection part 9 is fixedly installed inside the first steel pipe 6 and the second steel pipe 7. The first positioning connection part 9 is used to connect the first vertical steel pipe connector 8. The first positioning connection part 9 is rivet-shaped and includes a straight rod part and a limiting part. Both the straight rod part and the limiting part are cylindrical. The diameter of the limiting part is larger than that of the straight rod part. The straight rod part is welded and fixed to the inner wall of the first steel pipe 6 and the second steel pipe 7 respectively. The first steel pipe 6 and the second steel pipe 7 can each be fitted with a separate first vertical steel pipe connector 8, and they are compatible. The two opposite ends of the first vertical steel pipe connector 8 along its length direction have a first vertical insertion notch 10. The first vertical insertion notch 10 is used to engage the first positioning connection part 9. This arrangement facilitates insertion and positioning, making the connection between the first vertical steel pipe connector 8 and the corresponding steel pipe tighter and more reliable.

[0066] The upper part of the first steel pipe 6 and the upper part of the second steel pipe 7 are respectively connected to the first vertical steel pipe connector 8. The first vertical steel pipe connector 8 on the upper part of the first steel pipe 6 is used to connect the block structure installed on the upper part of the block structure, and the first vertical steel pipe connector 8 on the upper part of the second steel pipe 7 is used to connect the block structure at the same height.

[0067] If both the first steel pipe 6 and the second steel pipe 7 are square steel pipes, then the first vertical steel pipe connector 8 is also a square steel pipe. The first vertical steel pipe connector 8 can be appropriately inserted into the first steel pipe 6 and the second steel pipe 7. First vertical insertion notches 10 are respectively opened on the four walls at both ends of the first vertical steel pipe connector 8, for a total of 8 first vertical insertion notches 10. At this time, a first positioning connection part 9 is welded and fixed on the four walls at both ends of the first steel pipe 6, for a total of 8 first positioning connection parts 9. A first positioning connection part 9 is also welded and fixed on the four walls at both ends of the second steel pipe 7, for a total of 8 first positioning connection parts 9. During installation, each first positioning connection part 9 corresponds to a first vertical insertion notch 10. If both the first steel pipe 6 and the second steel pipe 7 are round steel pipes, then the first vertical steel pipe connector 8 is also a round steel pipe. The first vertical steel pipe connector 8 can be inserted into the first steel pipe 6 and the second steel pipe 7 in a corresponding manner. Each end of the first vertical steel pipe connector 8 has four first vertical insertion notches 10, and the spacing between adjacent first vertical insertion notches 10 at the same end is the same, for a total of eight first vertical insertion notches 10. At this time, each end of the first steel pipe 6 has four first positioning connection parts 9 welded and fixed to the inner wall, and the spacing between adjacent first positioning connection parts 9 at the same end is the same, for a total of eight first positioning connection parts 9. Each end of the second steel pipe 7 has four first positioning connection parts 9 welded and fixed to the inner wall, and the spacing between adjacent first positioning connection parts 9 at the same end is the same, for a total of eight first positioning connection parts 9. During installation, each first positioning connection part 9 is located in a corresponding first vertical insertion notch 10. In this embodiment, the types of the first steel pipe 6 and the second steel pipe 7 are consistent with those in embodiment 1, both being square steel pipes.

[0068] Example 3

[0069] like Figure 2 As shown, based on embodiment 1 or 2, a first reinforcing connection part 11 is fixedly installed on the outer side of the first steel pipe 6 and the second steel pipe 7. The first reinforcing connection part 11 is fixedly connected to the block body 1. The first reinforcing connection part 11 is welded and fixed to the outer wall of the first steel pipe 6 and the second steel pipe 7 respectively. During the pouring, the first reinforcing connection part 11 is directly poured and fixed inside the block body 1, so that the steel pipe can be stably and reliably integrated with the block body 1. The first reinforcing connection part 11 is a steel bar, a structural steel or a rivet. In this embodiment, the first reinforcing connection part 11 is in the shape of a rivet.

[0070] Example 4

[0071] like Figures 4 to 7As shown, the prefabricated steel pipe block mechanism includes a block base 12. One end of the block base 12 has a third upper connecting part 13 and a third lower connecting notch 14. A third steel pipe 15 is fixedly installed inside the opposite end. A fourth steel pipe 16 is fixedly installed inside the third upper connecting part 13. At least one end of the third steel pipe 15 and at least one end of the fourth steel pipe 16 are used to connect to a second vertical steel pipe connector 17. The third upper connecting part 13 and the third lower connecting notch 14 correspond to and match the second upper connecting notch 5 and the second lower connecting part 4 in any one of embodiments 1 to 3, respectively. The thickness and height of the block mechanism in this embodiment are the same as the thickness and height of the block structure in the aforementioned embodiments. The third upper connecting part 13 is located above the third lower connecting notch 14. The upper surface of the third upper connecting part 13 is flush with the upper surface of the block foundation 12 and both are horizontal. The thickness of the third upper connecting part 13 is the same as the thickness of the block foundation 12. The upper and lower ends of the third steel pipe 15 and the fourth steel pipe 16 are open. The steel pipes are hollow and have cavities. The two ends of the third steel pipe 15 pass through the upper and lower surfaces of the third upper connecting part 13, and the two ends of the fourth steel pipe 16 pass through the upper and lower surfaces of the block foundation 12. A horizontal fifth steel pipe 18 is fixedly installed at the opposite end of the block foundation 12. The fifth steel pipe 18 is connected to the third steel pipe 15 and is used to connect the horizontal steel pipe connector 19. The third steel pipe 15, the fourth steel pipe 16, and the fifth steel pipe 18 can be round steel pipes or square steel pipes. In this embodiment, they are square steel pipes.

[0072] The block foundation 12 is made of ordinary aerated concrete or high-strength ceramsite concrete. Combined with the aforementioned structural design, it is lighter than ordinary density concrete of the same volume and strength grade, making transportation and hoisting more convenient and cost-effective.

[0073] During the production of the block mechanism, a mold of the corresponding structural dimensions is prepared, the processed third steel pipe 15, fourth steel pipe 16, and fifth steel pipe 18 are positioned in the corresponding positions in the mold, and concrete is poured into the mold, compacted, and after preliminary curing, a single block mechanism is formed.

[0074] Furthermore, the lower end face of the third upper connecting part 13 is a horizontal plane, which further ensures the reliability and convenience of the connection between the block mechanism and the block structure of the aforementioned embodiment. In this embodiment, the lower end face of the third upper connecting part 13 is a horizontal plane, and the upper end face of the second lower connecting part 4 in the aforementioned embodiment is a horizontal plane, making the end matching connection between the block mechanism and the block structure of the aforementioned embodiment more reliable and convenient. The heights of the third upper connecting part 13 and the third lower connecting notch 14 are both half the height of the block foundation 12, that is, the heights of the third upper connecting part 13 and the third lower connecting notch 14 are the same. At the same time, they are the same as the heights of the first upper connecting part 2, the first lower connecting notch 3, the second lower connecting part 4, and the second upper connecting notch 5 in the aforementioned embodiment, which further improves the standardization of the block mechanism. In the process of connecting the block mechanism with the block structure of the aforementioned embodiment, the corresponding matching work of the connecting part and the connecting notch is eliminated, that is, the connecting part and the connecting notch can match each other, which further improves the construction efficiency.

[0075] Example 5

[0076] like Figure 5 , 6 As shown in Figure 7, based on Embodiment 4, a second positioning connection part 20 is fixedly installed inside both the third steel pipe 15 and the fourth steel pipe 16. The second positioning connection part 20 is used to connect the second vertical steel pipe connector 17. The second positioning connection part 20 is rivet-shaped and includes a straight rod part and a limiting part. Both the straight rod part and the limiting part are cylindrical. The diameter of the limiting part is larger than that of the straight rod part. The straight rod part is welded and fixed to the inner wall of the third steel pipe 15 and the fourth steel pipe 16 respectively. Each of the third steel pipe 15 and the fourth steel pipe 16 can be fitted with a separate second vertical steel pipe connector 17, and they are compatible. The two opposite ends of the second vertical steel pipe connector 17 along its length direction have a second vertical insertion notch 21. The second vertical insertion notch 21 is used to engage the second positioning connection part 20. This arrangement facilitates insertion and positioning, making the connection between the second vertical steel pipe connector 17 and the corresponding steel pipe tighter and more reliable.

[0077] The upper parts of the third steel pipe 15 and the fourth steel pipe 16 are each connected to a second vertical steel pipe connector 17. The second vertical steel pipe connector 17 on the upper part of the third steel pipe 15 is used to connect the block mechanism installed on the upper part of the block mechanism, and the second vertical steel pipe connector 17 on the upper part of the fourth steel pipe 16 is used to connect the second lower connecting part 4 of the block structure in the aforementioned embodiment.

[0078] If both the third steel pipe 15 and the fourth steel pipe 16 are square steel pipes, then the second vertical steel pipe connector 17 is also a square steel pipe. The second vertical steel pipe connector 17 can be appropriately inserted into the third steel pipe 15 and the fourth steel pipe 16. Each of the four walls at both ends of the second vertical steel pipe connector 17 has a second vertical insertion notch 21, for a total of eight second vertical insertion notches 21. At this time, each of the four walls at both ends of the third steel pipe 15 has a second positioning connection part 20 welded and fixed, for a total of eight second positioning connection parts 20. Similarly, each of the four walls at both ends of the fourth steel pipe 16 has a second positioning connection part 20 welded and fixed, for a total of eight second positioning connection parts 20. During installation, each second positioning connection part 20 corresponds to a second vertical insertion notch 21. If both the third steel pipe 15 and the fourth steel pipe 16 are round steel pipes, then the second vertical steel pipe connector 17 is also a round steel pipe. Part 17 can be adapted to be inserted into the third steel pipe 15 and the fourth steel pipe 16. Each end of the second vertical steel pipe connector 17 has four second vertical insertion notches 21, and the spacing between adjacent second vertical insertion notches 21 at the same end is the same, for a total of eight second vertical insertion notches 21.

Each end of the fourth steel pipe 16 has four second positioning connection parts 20 welded and fixed to the inner wall, and the spacing between adjacent second positioning connection parts 20 at the same end is the same, for a total of eight second positioning connection parts 20. During installation, each second positioning connection part 20 is located in a corresponding second vertical insertion notch 21. In this embodiment, the types of the third steel pipe 15 and the fourth steel pipe 16 are consistent with those in embodiment 4, both being square steel pipes.

[0079] Example 6

[0080] like Figure 6 As shown, based on embodiment 4 or 5, a second reinforcing connection 22 is fixedly installed on the outer side of the third steel pipe 15 and the fourth steel pipe 16. The second reinforcing connection 22 is fixedly connected to the block foundation 12. The second reinforcing connection 22 is welded and fixed to the outer wall of the third steel pipe 15 and the fourth steel pipe 16 respectively. During the pouring, the second reinforcing connection 22 is directly poured and fixed in the block foundation 12, so that the steel pipe can form a stable and reliable whole with the block foundation 12. The second reinforcing connection is a steel bar, a structural steel or a rivet. In this embodiment, the second reinforcing connection 22 is in the shape of a rivet.

[0081] Example 7

[0082] like Figure 8As shown, the prefabricated type 1 node includes two block structures as described in any one of embodiments 1 to 3 above. The two block structures are parallel. The first upper connecting part 2 of the first block structure is located above the second lower connecting part 4 of the second block structure and matches the second upper connecting notch 5 of the second block structure. The lower part of the first steel pipe 6 of the first block structure is connected to the upper part of the second steel pipe 7 of the second block structure through the first vertical steel pipe connector 8.

The two block structures are perpendicular to each other. The first upper connecting part 2 of the first block structure is located above the second lower connecting part 4 of the second block structure and matches the second upper connecting notch 5 of the second block structure. The lower part of the first steel pipe 6 of the first block structure is connected to the upper part of the second steel pipe 7 of the second block structure through the first vertical steel pipe connector 8.

[0089] L-shaped node construction method:

[0090] The lower part of a first vertical steel pipe connector 8 is installed to the upper part of the second steel pipe 7 of the second block structure. Then, the lower part of the first steel pipe 6 of the first block structure is installed from top to bottom to the upper part of the first vertical steel pipe connector 8. At this time, the two block structures are perpendicular. The first upper connection part 2 of the first block structure is located above the second lower connection part 4 of the second block structure and matches the second upper connection notch 5 of the second block structure. The connection process is convenient and quick.

[0091] After the L-shaped node is installed, concrete can be poured into the connected steel pipes to form a stable whole.

[0092] When L-shaped nodes need to be installed in an overlapping manner in the height direction, the upper block structure and the lower block structure are still connected by the first vertical steel pipe connector 8. The cavities of the steel pipes stacked sequentially in the height direction are interconnected, and concrete can be poured into the interconnected steel pipes to further strengthen the entire building structure.

[0093] Example 9

[0094] like Figures 10 to 14 As shown, the prefabricated T-shaped node includes two aforementioned block structures and one aforementioned block mechanism. The block foundation 12 and the block body 1 have the same thickness and height. The first upper connecting part 2 of the first block structure is located in the second upper connecting notch 5 of the second block structure and is compatible with it. The first upper connecting part 2 of the first block structure and the second lower connecting part 4 of the second block structure are connected by a first vertical steel pipe connector 8. The first block structure and the second block structure are parallel.

[0095] The third upper connecting part 13 of the block mechanism matches the second upper connecting notch 5 of the block structure, and the third lower connecting notch 14 of the block mechanism matches the second lower connecting part 4 of the block structure.

[0096] A horizontal steel pipe connector 19 is fixedly installed on the inner side of the first upper connecting part 2 of the first block structure. The horizontal steel pipe connector 19 is connected to the fifth steel pipe 18. The block mechanism is perpendicular to the block structure.

[0097] The fifth steel pipe 18, the third steel pipe 15, and the first steel pipe 6 of the first block structure are connected.

[0098] A third positioning connection part 23 is fixedly installed inside the fifth steel pipe 18. The third positioning connection part 23 is used to connect the horizontal steel pipe connector 19. The third positioning connection part 23 is rivet-shaped and includes a straight rod part and a limiting part. Both the straight rod part and the limiting part are cylindrical. The diameter of the limiting part is larger than that of the straight rod part. The straight rod part is welded and fixed to the inner wall of the fifth steel pipe 18. The inner end of the horizontal steel pipe connector 19 has a horizontal insertion notch 24. The horizontal insertion notch 24 is used to snap the third positioning connection part 23. This setting facilitates insertion and positioning, making the connection between the horizontal steel pipe connector 19 and the fifth steel pipe 18 tighter and more reliable.

[0099] The fifth steel pipe 18 can be a round steel pipe or a square steel pipe, but its type is consistent with that of the aforementioned third steel pipe 15 and first steel pipe 6. The type of the horizontal steel pipe connector 19 is consistent with that of the fifth steel pipe 18. If the fifth steel pipe 18 is a square steel pipe, then the horizontal steel pipe connector 19 is also a square steel pipe. The horizontal steel pipe connector 19 can be inserted into the fifth steel pipe 18 in a suitable manner. Horizontal insertion notches 24 are respectively opened on the four walls of the inner end of the horizontal steel pipe connector 19, for a total of 4 horizontal insertion notches 24. At this time, a third positioning connection part 23 is welded and fixed on each of the four walls of the fifth steel pipe 18, for a total of 4 third positioning connection parts 23. During installation, each third positioning connection part 23 is located at the corresponding position. Within a horizontal insertion notch 24; if the fifth steel pipe 18 is a round steel pipe, then the horizontal steel pipe connector 19 is also a round steel pipe. The horizontal steel pipe connector 19 can be inserted into the fifth steel pipe 18 in a suitable manner. The inner end of the horizontal steel pipe connector 19 has 4 horizontal insertion notches 24, and the spacing between adjacent horizontal insertion notches 24 is the same, for a total of 4 horizontal insertion notches 24. At this time, 4 third positioning connection parts 23 are welded and fixed to the inner wall of the fifth steel pipe 18. The spacing between adjacent third positioning connection parts 23 is the same, for a total of 4 third positioning connection parts 23. During installation, each third positioning connection part 23 is located within a horizontal insertion notch 24; here, the fifth steel pipe 18 is specifically a square steel pipe.

[0100] Construction method of prefabricated T-shaped joints:

[0101] First, connect the two block structures: insert the lower part of a first vertical steel pipe connector 8 into the upper part of the second steel pipe 7 of the second block structure, and then install the lower part of the first steel pipe 6 of the first block structure from top to bottom into the upper part of the first vertical steel pipe connector 8. At this time, the first upper connecting part 2 of the first block structure is located above the second lower connecting part 4 of the second block structure and matches the second upper connecting notch 5 of the second block structure. The two block structures are parallel.

[0102] Then connect the block mechanism to the first block structure: insert the horizontal steel pipe connector 19 horizontally into the fifth steel pipe 18 to achieve the connection between the block mechanism and the first block structure.

[0103] After the T-shaped node is installed, concrete can be poured into the connected steel pipes to form a stable whole.

[0104] When T-shaped nodes need to be installed in an overlapping manner in the height direction, the upper block structure and the lower block structure are still connected by the first vertical steel pipe connector 8, and the upper block mechanism and the lower block mechanism are still connected by the second vertical steel pipe connector 17. The cavities of the steel pipes stacked sequentially in the height direction are interconnected. The cavities of the third steel pipe 15, the fifth steel pipe 18 of the block mechanism, and the first steel pipe 6 of the first block structure are interconnected. Concrete can be poured into the interconnected steel pipes to further strengthen the entire building structure.
