Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a connection structure between SRC column steel frame and RC beam steel reinforcement and its construction method. Background Technology

[0002] Steel-concrete composite (SRC steel-reinforced concrete structure) is one of the main structural forms for future multi-story and high-rise buildings. Due to the lower cost of reinforced concrete, the combination of SRC steel columns and RC (reinforced concrete structure) beam reinforcement is more suitable for promotion and application in my country's engineering practice.

[0003] In the existing technology, the steel frame of SRC column and the steel reinforcement of RC beam are not easy to assemble and disassemble, and the angle is not easy to adjust after installation. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, a connection structure for SRC column steel frame and RC beam reinforcement and its construction method are provided to solve the problems that existing SRC column steel frame and RC beam reinforcement are inconvenient to assemble and disassemble, and that it is inconvenient to adjust the angle after installation.

[0005] To achieve the above objectives, a connection structure between the steel frame of an SRC column and the reinforcing bars of an RC beam is provided, comprising:

[0006] A connecting sleeve, wherein the outer wall of the connecting sleeve is provided with a locking hole, and the connecting sleeve has a first end opposite to each other and a second end for fitting the reinforcing bars of the RC beam;

[0007] The column mounter includes a base plate and an adapter plate for mounting SRC column steel frames. The base plate and the adapter plate are disposed opposite to each other. The base plate has a shaft hole. A plug is formed on the side of the adapter plate facing the base plate. The plug is rotatably inserted into the shaft hole. A through hole is formed in the plug. A pressing block is slidably disposed in the through hole. A receiving hole is formed on the other side of the adapter plate, which is offset from the plug. A locking block is slidably disposed in the receiving hole. A locking connector for insertion into a locking hole is provided on the outer side of the opening of the receiving hole. The adapter plate is equipped with a drive structure for driving the pressing block to extend out of the through hole and the locking block to extend out of the receiving hole and be inserted into the first end of the connecting sleeve.

[0008] Furthermore, there are two pressure blocks, which are slidably disposed at both ends of the through hole. A first screw is rotatably installed in the through hole along the axial direction of the through hole. Threaded holes are opened on the opposite sides of the two pressure blocks. The two ends of the first screw are screwed into the threaded holes of the two pressure blocks. The drive structure is connected to the first screw.

[0009] Furthermore, a second screw is rotatably mounted in the receiving hole and arranged along the axial direction of the receiving hole. The locking block has a threaded hole, and one end of the second screw is screwed into the threaded hole of the locking block. The driving structure is connected to the second screw.

[0010] Furthermore, the adapter plate has a first channel and a second channel communicating with the through hole, the second channel penetrating the receiving hole and communicating with the first channel, and the driving structure includes:

[0011] A rotating shaft is rotatably mounted in the second channel;

[0012] A drive shaft is rotatably mounted in the first channel. One end of the drive shaft is connected to a first worm gear. A first worm wheel is coaxially mounted on the first screw. The first worm gear meshes with the first worm wheel. The other end of the drive shaft is connected to one end of a rotating shaft via a gear. A second worm gear is coaxially mounted on the rotating shaft. A second worm wheel is coaxially mounted on the second screw. The second worm gear meshes with the second worm wheel.

[0013] The adapter plate has a through hole communicating with the second channel, and the other end of the rotating shaft has a plurality of insertion holes arranged along the circumferential direction of the rotating shaft. One end of the locking rod is elastically installed in the through hole, and the other end of the locking rod extends into the second channel and is inserted into a insertion hole to lock the rotating shaft.

[0014] Furthermore, the wall of the perforation is formed with a groove arranged along the axial direction of the perforation, one end of the locking rod is formed with a slider, the slider is slidably disposed in the groove, and a push spring for pushing the slider toward the second channel is installed between the slider and the groove.

[0015] Furthermore, a limiting groove is formed on the inner wall of the shaft hole, and the limiting groove is arranged in a circle along the circumference of the shaft hole. The plug-in is formed with an anti-detachment flange, which is slidably disposed in the limiting groove.

[0016] Furthermore, the locking connector is mounted on the other side of the adapter plate via a support rod.

[0017] Furthermore, a plurality of anti-slip protrusions are formed on the side of the pressing block facing the hole wall of the shaft hole.

[0018] This invention provides a construction method for a connection structure between SRC column steel frame and RC beam reinforcement, comprising the following steps:

[0019] The base plates of the two anchors are respectively installed on opposite sides of the two SRC column steel frames, so that the base plates of the two anchors are collinear.

[0020] Connecting sleeves are fitted to both ends of the RC beam reinforcement;

[0021] Rotate the adapter plates of the two column attachments so that the receiving holes of the two column attachments are aligned with the preset installation positions of the RC beam reinforcement.

[0022] The RC beam reinforcement is embedded between the transition plates of the two column attachments, such that the locking connectors of the two column attachments are inserted into the locking holes of the connecting sleeves at both ends of the RC beam reinforcement, and the first end of the connecting sleeve at both ends of the RC beam reinforcement is aligned with the receiving hole of the transition plate of the two column attachments.

[0023] The drive structure of the column attachment drives the pressing block of the column attachment to extend out of the through hole of the column attachment connector to lock the base plate, and drives the locking block of the column attachment to extend out of the receiving hole of the adapter plate of the column attachment to be inserted into the first end of the connecting sleeve, thereby locking the RC beam reinforcement in the preset installation position.

[0024] The beneficial effects of this invention are as follows: During use, after the RC beam reinforcement is installed between two SRC column steel frames through the connection structure between the SRC column steel frame and the RC beam reinforcement, the position of the RC beam reinforcement is adjusted by rotating the plug and the shaft hole, so that the RC beam reinforcement is installed in the predetermined installation position. After the RC beam reinforcement is installed in the predetermined installation position, the driving structure pushes the pressing block out of the through hole to press against the inner wall of the shaft hole and lock the base plate. The driving structure also pushes the locking block out of the receiving hole so that one end of the locking block is inserted into the connecting sleeve. The connecting sleeve is locked to the adapter plate by the locking block and the locking connector. The connection structure between the SRC column steel frame and the RC beam reinforcement of this invention, when installing the RC beam reinforcement between the SRC column steel frames, on the one hand, allows for convenient and quick adjustment of the RC beam reinforcement position, and on the other hand, provides a more stable and reliable lock for the RC beam reinforcement position. This facilitates the combined installation of the column steel frame and the RC beam reinforcement, and improves the adjustment of the RC beam reinforcement setting angle after installation, thereby improving the construction efficiency of the steel-concrete composite structure.

[0031] The present application 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 merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0032] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] Reference Figures 1 to 5 As shown, the present invention provides a connection structure between the steel frame of an SRC column and the reinforcing bars of an RC beam, comprising: a connecting sleeve 1 and a column attachment 2.

[0034] In this embodiment, each end of the RC beam steel bar 4 is detachably installed on the SRC column steel frame 3 through the connecting sleeve 1 and the column attachment 2.

[0035] Specifically, the reinforcing sleeve 1 is installed at the end of the RC beam reinforcing bar 4. The reinforcing sleeve is threaded to the end of the RC beam reinforcing bar 4. The end of the RC beam reinforcing bar 4 also has an external thread adapted to the internal thread of the reinforcing sleeve.

[0036] In this embodiment, the outer wall of the connecting sleeve 1 is provided with a locking hole. The connecting sleeve has a first end facing each other and a second end for connecting the RC beam reinforcing bars 4.

[0037] The column anchor is installed on the SRC column steel frame 3. Two adjacent SRC column steel frames are arranged opposite each other. The RC beam reinforcement 4 is set on the two SRC column steel frames. The ends of the RC beam reinforcement 4 are detachably installed on the SRC column steel frame 3 through the connecting sleeve 1 and the column anchor 2.

[0038] Specifically, the post attachment 2 includes a base plate 21, an adapter plate 22, a connector 23, a pressing block 24, a locking block 25, and a driving structure.

[0039] The base plate 21 is used to mount the SRC column steel frame 3. In use, such as... Figure 1 and Figure 2 As shown, the substrate is fixed to the side of the SRC column steel frame.

[0040] The substrate 21 and the adapter plate 22 are disposed opposite to each other. The substrate 21 has a shaft hole. A connector 23 is formed on the side of the adapter plate 22 facing the substrate 21. The connector 23 is rotatably inserted into the shaft hole. A through hole a is formed in the connector 23. A pressing block 24 is slidably disposed in the through hole a. The pressing block can move along the axial direction of the through hole, that is, the pressing block can move along the radial direction of the shaft hole.

[0041] A receiving hole b is formed on the opposite side of the adapter plate 22 from the substrate. The receiving hole b is offset from the plug 23. The receiving hole b is not coaxial with the shaft hole, that is, it is eccentrically positioned.

[0042] A locking block 25 is slidably provided inside the receiving hole b. The locking block can move along the axial direction of the receiving hole. A locking connector 26 is provided on the outer side of the opening of the receiving hole b. The locking connector 26 is used to be inserted into the locking hole to connect the connecting sleeve.

[0043] The adapter plate 22 is equipped with a drive structure. The drive structure is used to drive the pressing block 24 and the locking block 25 in a coordinated manner. Specifically, the drive structure is used to drive the pressing block 24 to extend out of the through hole a and the locking block 25 to extend out of the receiving hole b so that they can be inserted into the first end of the connecting sleeve 1.

[0044] During use, after the RC beam reinforcement 4 is installed between two SRC column steel frames 3 through the connection structure between the SRC column steel frame and the RC beam reinforcement 4 of the present invention, the position of the RC beam reinforcement 4 is adjusted by rotating the plug and the shaft hole, so that the RC beam reinforcement 4 is installed in the predetermined installation position. After the RC beam reinforcement 4 is installed in the predetermined installation position, the driving structure pushes the pressing block out of the through hole to press against the inner wall of the shaft hole and lock the base plate. The driving structure also pushes the locking block out of the receiving hole so that one end of the locking block is inserted into the connecting sleeve. The connecting sleeve is locked to the adapter plate by the locking block and the locking connector. The connection structure between the SRC column steel frame and the RC beam reinforcement of the present invention, when installing the RC beam reinforcement between the SRC column steel frames, on the one hand, allows for convenient and quick adjustment of the RC beam reinforcement position, and on the other hand, provides a more stable and reliable lock for the RC beam reinforcement position. This facilitates the combined installation of the column steel frame and the RC beam reinforcement, and improves the adjustment of the RC beam reinforcement setting angle after installation, thereby improving the construction efficiency of the steel-concrete composite structure.

[0045] See Figures 1 to 3 There are two pressure blocks 24. The two pressure blocks 24 are slidably mounted at both ends of the through hole a. A first screw 241, rotatably mounted within the through hole a and arranged along the axial direction of the through hole a, is provided. Threaded holes are formed on opposite sides of the two pressure blocks 24. The two ends of the first screw 241 are screwed into the threaded holes of the two pressure blocks 24. A drive structure is connected to the first screw 241.

[0046] Continue reading Figure 2 and Figure 3A second screw 28 is rotatably mounted in the receiving hole b within the adapter plate. The second screw 28 is positioned along the axial direction of the receiving hole b. A threaded hole is provided in the locking block 25. One end of the second screw 28 is screwed into the threaded hole of the locking block 25. The drive structure is connected to the second screw 28 for transmission.

The second channel c passes through the receiving hole b and connects to the first channel. The first channel is arranged along the axial direction of the shaft hole. The second channel is arranged along the radial direction of the receiving hole. The first channel is perpendicular to the second channel. One end of the second channel connects to the first channel, and the other end of the second channel passes through the adapter plate.

[0049] A rotating shaft 271 is rotatably mounted in the second channel c. A drive shaft 272 is rotatably mounted in the first channel. One end of the drive shaft 272 is connected to a first worm gear. A first screw 241 is coaxially mounted with a first worm wheel. The first worm gear meshes with the first worm wheel. (See reference...) Figure 4 As shown, the other end of the drive shaft 272 is connected to one end of the rotating shaft 271 via a gear. A second worm gear is coaxially mounted on the rotating shaft 271. A second worm wheel is coaxially mounted on the second screw 28. The second worm gear meshes with the second worm wheel.

[0050] The adapter plate 22 has a through hole. The through hole connects to the second channel c. The other end of the rotating shaft 271 has multiple insertion holes. The multiple insertion holes are arranged along the circumference of the rotating shaft 271. One end of the locking rod 273 is elastically installed in the through hole. The other end of the locking rod 273 extends into the second channel c and is inserted into one of the insertion holes to lock the rotating shaft 271.

[0051] See Figure 5 The wall of the perforation has a groove formed along the axial direction of the perforation. A slider 274 is formed at one end of the locking rod 273. The slider 274 slides in the groove. A push spring 275 is installed between the slider 274 and the groove to push the slider 274 toward the second channel c.

[0052] When installing the RC beam reinforcement, first pull the locking rod towards the outside of the hole to release the lock on the rotating shaft, so that the shaft can then drive the pressing block and the locking block. After the RC beam reinforcement is set in the predetermined installation position, lock the RC beam reinforcement with the pressing block and the locking block, and then release the locking rod so that the locking rod is inserted into the hole of the rotating shaft.

[0053] In this embodiment, the other end of the rotating shaft is coaxially connected to a limiting disk, and an insertion hole is provided on the circumferential surface of the limiting disk. An annular groove is formed on the inner wall of the second channel, and the limiting disk is rotatably disposed within the annular groove. A through hole communicates with the second channel through the annular groove.

[0054] See Figure 3 A limiting groove is formed on the inner wall of the shaft hole. The limiting groove is arranged in a circle along the circumference of the shaft hole. The connector 23 is formed with an anti-detachment flange 231. The anti-detachment flange 231 is slidably disposed in the limiting groove.

[0055] Continue reading Figure 3 As shown, the locking connector 26 is mounted on the other side of the adapter plate 22 via a support rod.
