Description

Technical Field

[0001] This application relates to the technical field of prefabricated steel structures, and particularly to a prefabricated connecting sleeve. Background Art

[0002] A prefabricated building whose structural system is composed of steel (structural) members is called a prefabricated steel structure building.

[0003] In a prefabricated steel structure building, there are two connection methods between steel columns and crossbeams. One is the connection between steel columns and steel beams, and the other is the connection between steel columns and reinforced concrete frame beams.

[0004] Among them, when connecting a steel column and a reinforced concrete frame beam, it is necessary to first set up the steel column, and then weld the steel bars on the steel column on-site. The concrete frame beam is built through the steel bars.

[0005] However, due to the complexity of the construction site, sometimes the on-site operation space is narrow, which is not conducive to the welding operation of steel bars. And welding may damage the steel column, affecting the overall structural strength of the steel column, and there may even be a situation where the welding is not firm. Utility Model Content

[0006] In order to facilitate the connection between steel bars and steel columns, this application provides a prefabricated connecting sleeve. The prefabricated connecting sleeve provided by this application adopts the following technical solutions:

[0007] A prefabricated connecting sleeve includes two oppositely arranged clamping plates and a connecting piece for connecting the two clamping plates. The clamping plates are provided with a plurality of connectors for inserting steel bars;

[0008] The connecting piece includes a fixing block installed on the clamping plate and a high-strength bolt passing through the fixing block. The fixing block is provided with a threaded hole for the high-strength bolt to be screwed into.

[0009] By adopting the above technical solutions, when the clamping plates are used, the two clamping plates are sleeved on the steel column. By screwing the high-strength bolt into the threaded hole of the fixing block, the two clamping plates are fixedly connected to the steel column. Finally, the steel bar is inserted into the connector; this connection method does not require on-site welding, saves installation time, and is less likely to have welding problems.

[0010] Optionally, the clamping plate includes a first surrounding plate and a second surrounding plate that are perpendicularly connected to each other. A plurality of the connectors are evenly distributed on the outer sides of the first surrounding plate and the second surrounding plate. The connector has an internal thread for the steel bar to be screwed into.

[0011] By adopting the above technical solutions, the connecting hole is provided with an internal thread, and the end of the steel bar has an external thread. When connecting, the end of the steel bar is screwed into the connecting hole, so that the steel bar and the connector are connected by threads.

[0012] Optionally, the fixing block is a nut, and the axis of its threaded hole is in the vertical direction.

[0013] Optionally, the fixing block is plate-shaped, and the axis of its threaded hole is in the horizontal direction.

[0014] Optionally, the connecting member further includes a rotating buckle block rotatably connected to the first surrounding plate and a plug rod arranged on the second surrounding plate, and the rotating buckle block is provided with a slot for the plug rod to insert.

[0015] By adopting the above technical solution, when the two clamping plates are connected, the first surrounding plate of one clamping plate is attached to the second surrounding plate of the other clamping plate. At this time, the rotating buckle block is flipped so that the rotating buckle block is sleeved on the plug rod, that is, the plug rod is inserted into the slot. At this time, the fixing blocks of the first surrounding plate and the second surrounding plate correspond to each other, which is convenient for the high-strength bolt to be screwed into the fixing block; moreover, the connection between the plug rod and the rotating buckle block can also improve the structural strength between the two clamping plates, making the connection between the clamping plate and the steel column more stable.

[0016] Optionally, a nut is provided at the end of the plug rod.

[0017] By adopting the above technical solution, after the rotating buckle block is sleeved on the plug rod, a nut is screwed onto the end of the plug rod. Through the blocking effect of the nut, the rotating buckle block is not easily slipped off the plug rod.

[0018] In summary, the present application includes at least one of the following beneficial technical effects:

[0019] 1. When the clamping plate is in use, the two clamping plates are sleeved on the steel column. At this time, the fixing blocks of the first surrounding plate and the second surrounding plate are abutted against each other. The high-strength bolt is passed through the above two fixing blocks, and the two clamping plates are fixed to the steel column by the high-strength bolt;

[0020] 2. When the two clamping plates are connected, the rotating buckle block is flipped so that the rotating buckle block is sleeved on the plug rod, that is, the plug rod is inserted into the slot. At this time, the fixing blocks of the first surrounding plate and the second surrounding plate correspond to each other, which is convenient for the high-strength bolt to be screwed into the fixing block;

[0021] 3. After the rotating buckle block is sleeved on the plug rod, a nut is screwed onto the end of the plug rod. Through the blocking effect of the nut, the rotating buckle block is not easily slipped off the plug rod. Description of the Drawings

[0033] Referring to Figure 2 and Figure 3 , specifically, the splint 1 includes a first enclosing plate 11 and a second enclosing plate 12 that are perpendicular to each other. The first enclosing plate 11 and the second enclosing plate 12 are connected by welding or integrally provided, and the cross-section of the splint 1 after connection is L-shaped.

[0034] A plurality of connectors 13 are evenly distributed on the outer sides of the first enclosing plate 11 and the second enclosing plate 12. The connector 13 has a connection hole 14 for the steel bar 4 to be inserted. The specification size of the connector 13 can be customized according to the specification size of the steel bar, which is convenient for selecting a suitable specification for use at the construction site; and, an internal thread is provided in the connection hole 14, and the end of the steel bar 4 has an external thread. When connecting, the end of the steel bar 4 is screwed into the connection hole 14, so that the steel bar 4 is threadedly connected to the connector 13.

[0035] The connecting member 2 includes a fixing block 21 and a high-strength bolt 22. The fixing block 21 is fixed to the first enclosing plate 11 and the second enclosing plate 12 by welding. The fixing block 21 is provided with a threaded hole for the high-strength bolt 22 to pass through, and the high-strength bolt 22 passes through the threaded hole to connect the two fixing blocks 21.

[0036] When the clamping plates 1 are in use, the two clamping plates 1 are sleeved on the steel column 3. At this time, the fixing blocks 21 of the first enclosing plate 11 are in contact with the fixing blocks 21 of the second enclosing plate 12. The high-strength bolt 22 is passed through the above two fixing blocks 21, and the two clamping plates 1 are fixed to the steel column 3 by the high-strength bolt 22.

[0037] See Figure 4 , in one embodiment, the fixing block 21 is a nut, and the axis of the threaded hole is in the vertical direction; when the two clamping plates 1 are connected, the fixing block 21 of the first enclosing plate 11 of one clamping plate 1 is in contact with the fixing block 21 of the second enclosing plate 12 of the other clamping plate 1 up and down, and the threaded holes of the above two fixing blocks 21 form a vertical line, so that the high-strength bolt 22 is screwed into the threaded holes of the two fixing blocks 21.

[0038] See Figure 5 , in another embodiment, the fixing block 21 is plate-shaped, and the fixing block 21 forms a 45-degree angle with the first enclosing plate 11 or the second enclosing plate 12; when the two clamping plates 1 are connected, the fixing block 21 of the first enclosing plate 11 of one clamping plate 1 is in contact with the fixing block 21 of the second enclosing plate 12 of the other clamping plate 1, and the threaded holes of the above two fixing blocks 21 form a horizontal line, so that the high-strength bolt 22 is screwed into the threaded holes of the two fixing blocks 21.

[0039] See Figure 6 , in addition, the connecting member 2 further includes a rotating buckle block 23 and a plug rod 24.

At this time, the rotating buckle block 23 is flipped so that the rotating buckle block 23 is sleeved on the plug rod 24, that is, the plug rod 24 is inserted into the slot 25. At this time, the fixing block 21 of the first enclosing plate 11 corresponds to the fixing block 21 of the second enclosing plate 12, which is convenient for the high-strength bolt 22 to be screwed into the fixing block 21.

[0041] To improve the stability of the plug rod 24 in the slot 25, a nut 26 is provided at the end of the plug rod 24, and the nut 26 is threadedly connected to the plug rod 24; after the rotating buckle block 23 is sleeved on the plug rod 24, the nut 26 is screwed onto the end of the plug rod 24. Through the blocking action of the nut 26, the rotating buckle block 23 is not easily disengaged from the plug rod 24.

[0042] The implementation principle of an assembled connection sleeve in an embodiment of this application is as follows: When the connection sleeve is in use, two clamping plates 1 are attached to the steel column 3. Then, the rotating buckle 23 is flipped so that the rotating buckle 23 is sleeved on the insertion rod 24. After that, a nut 26 is sleeved on the insertion rod 24. Next, a high-strength bolt 22 is screwed into the fixing block 21 to fixedly connect the two clamping plates 1. Finally, a steel bar 4 is screwed into the connector 13.
