DETAILED DESCRIPTION

[0019] The following is combined with Figure 1-7 This application is described in further detail.

[0020] The present application embodiment discloses a prefabricated concrete beam-column node connection device.

In this embodiment, the horizontal steel sleeve 4 is connected to the middle part of the vertical steel sleeve 3, that is, the horizontal steel sleeve 4 and the vertical steel sleeve 3 together form a three-way steel pipe.

[0021] like Figure 2 As shown, the vertical steel sleeve 3 is provided with two horizontally arranged first slide grooves 31, and the two first slide grooves 31 are arranged in sequence along the vertical direction. A first positioning cylinder 32 is slidably embedded in the first slide groove 31, and the first positioning cylinder 32 is provided with a first guide surface 321 in an annular shape at one end facing the frame column 1; the first positioning cylinder 32 and the vertical steel sleeve 3 are commonly connected with the same first spring 322, one end of the first spring 322 is fixedly connected to the first positioning cylinder 32, and the other end of the first spring 322 is fixedly connected to the vertical steel sleeve 3.

[0022] When the vertical steel sleeve 3 is slidably mounted on the frame column 1, the first guide surface 321 will contact the upper end surface of the frame column 1, so that the first positioning cylinder 32 sinks into the first slide groove 31. At this time, the first spring 322 will be in a compressed state, and the vertical steel sleeve 3 will be able to slide on the frame column 1, so that the vertical steel sleeve 3 and the horizontal steel sleeve 4 can slide to the beam-column node.

[0023] The frame column 1 is provided with two first positioning grooves 11 for the first positioning cylinder 32 to be engaged. When the vertical steel sleeve 3 and the horizontal steel sleeve 4 slide to the beam-column node, the first positioning cylinder 32 will correspond to the first positioning groove 11. At this time, the first spring 322 will return to its natural state, so that the first positioning cylinder 32 is inserted into the first positioning groove 11, thereby realizing the preliminary limiting of the vertical steel sleeve 3 and the horizontal steel sleeve 4.

[0024] A second horizontally arranged slot 33 is provided at both upper and lower ends of the vertical steel sleeve 3. The two second slots 33 are arranged in sequence along the vertical direction. A second positioning cylinder 34 is slidably embedded in the second slot 33. The second positioning cylinder 34 is provided with a second annular guide surface 341 at one end facing the frame column 1. The second positioning cylinder 34 and the vertical steel sleeve 3 are commonly connected with the same second spring 342. One end of the second spring 342 is fixedly connected to the second positioning cylinder 34, and the other end of the second spring 342 is fixedly connected to the vertical steel sleeve 3.

[0025] When the vertical steel sleeve 3 is slidably mounted on the frame column 1, the second guide surface 341 will abut against the upper end surface of the frame column 1, so that the second positioning cylinder 34 sinks into the second slide groove 33. At this time, the second spring 342 will be in a compressed state, and the vertical steel sleeve 3 will be able to slide on the frame column 1, so that the vertical steel sleeve 3 and the horizontal steel sleeve 4 can slide to the beam-column node.

[0026] Two second positioning grooves 12 for the second positioning cylinder 34 to be engaged are provided on the frame column 1. When the vertical steel sleeve 3 and the horizontal steel sleeve 4 slide to the beam-column node, the second positioning cylinder 34 will correspond to the second positioning groove 12. At this time, the second spring 342 will return to its natural state, so that the second positioning cylinder 34 is inserted into the second positioning groove 12, realizing secondary positioning of the vertical steel sleeve 3 and the horizontal steel sleeve 4.

[0027] When the vertical steel sleeve 3 and the horizontal steel sleeve 4 are limited at the beam-column node, the worker will insert the frame beam 2 into the horizontal steel sleeve 4 and force the frame beam 2 to press against the side of the frame column 1 to complete the docking of the frame beam 2 and the frame column 1.

[0028] A third vertically arranged slot 41 is provided on both the upper and lower sides of the horizontal steel sleeve 4. The two third slots 41 are arranged in sequence along the vertical direction. A third positioning cylinder 42 is slidably embedded in the third slot 41. The third positioning cylinder 42 is provided with a third annular guide surface 421 at one end facing the frame beam 2. The third positioning cylinder 42 and the horizontal steel sleeve 4 are commonly connected with the same third spring 422. One end of the third spring 422 is fixedly connected to the third positioning cylinder 42, and the other end of the third spring 422 is fixedly connected to the horizontal steel sleeve 4.

[0029] During the process of the frame column 1 sliding into the horizontal steel sleeve 4, the third guide surface 421 will contact the side end surface of the frame beam 2, so that the third positioning cylinder 42 sinks into the third slide groove 41. At this time, the third spring 422 will be in a compressed state, and the frame beam 2 will be able to slide in the horizontal steel sleeve 4 so that the frame beam 2 can dock with the frame column 1.

[0030] The upper and lower sides of the frame beam 2 are provided with a third positioning groove 21 for the third positioning cylinder 42 to be clamped. After the frame beam 2 is connected to the frame column 1, the third positioning cylinder 42 will correspond to the third positioning groove 21. At this time, the third spring 422 will return to its natural state, so that the third positioning cylinder 42 is inserted into the third positioning groove 21, realizing three-way limiting of the vertical steel sleeve 3 and the horizontal steel sleeve 4.

[0031] A fourth sliding groove 43 is vertically arranged on both the upper and lower sides of the horizontal steel sleeve 4. The two fourth sliding grooves 43 are arranged in sequence along the vertical direction. A fourth positioning cylinder 44 is slidably embedded in the fourth sliding groove 43. The fourth positioning cylinder 44 is provided with a fourth guide surface 441 in an annular shape at one end facing the frame beam 2. The fourth positioning cylinder 44 and the horizontal steel sleeve 4 are commonly connected with the same fourth spring 442. One end of the fourth spring 442 is fixedly connected to the fourth positioning cylinder 44, and the other end of the fourth spring 442 is fixedly connected to the horizontal steel sleeve 4.

[0032] During the process of the frame column 1 sliding and embedding into the horizontal steel sleeve 4, the fourth guide surface 441 will abut against the side end surface of the frame beam 2, so that the fourth positioning cylinder 44 sinks into the fourth slide groove 43. At this time, the fourth spring 442 will be in a compressed state, and the frame beam 2 will be able to slide in the horizontal steel sleeve 4 so that the frame beam 2 can dock with the frame column 1.

[0033] The upper and lower sides of the frame beam 2 are provided with fourth positioning grooves 22 for the fourth positioning cylinder 44 to be clamped. After the frame beam 2 is connected to the frame column 1, the fourth positioning cylinder 44 will correspond to the fourth positioning groove 22. At this time, the fourth spring 442 will return to its natural state, so that the fourth positioning cylinder 44 is inserted into the fourth positioning groove 22, thereby realizing four-fold limiting of the vertical steel sleeve 3 and the horizontal steel sleeve 4.

[0034] The first plug column 5 is slidably embedded in the first positioning tube 32, and the frame column 1 is provided with two first slots 13 arranged horizontally, and the first slots 13 correspond to the first plug column 5 one by one; the frame beam 2 is provided with two fifth slots 25 arranged horizontally, and the fifth slots 25 correspond to the first plug column 5 one by one. After the vertical steel sleeve 3 and the horizontal steel sleeve 4 are connected, the worker will insert the first plug column 5 into the first positioning tube 32, the first slot 13 and the fifth slot 25 in sequence, so that the vertical steel sleeve 3, the frame column 1 and the frame beam 2 are connected as a whole.

[0035] The fourth plug column 8 is slidably embedded in the fourth positioning cylinder 44, and the frame beam 2 is provided with a fourth slot 24 that runs through the upper and lower sides of the frame beam 2. After the first plug column 5 is inserted into the first positioning cylinder 32, the first slot 13 and the fifth slot 25, the worker presses down the fourth plug column 8 on the upper side and pushes up the fourth plug column 8 on the lower side, so that both fourth plug columns 8 are inserted into the fourth slot 24, and at this time the horizontal steel sleeve 4 and the frame beam 2 are connected as a whole.

[0036] The first plug column 5 is provided with a socket 52, and the socket 52 corresponds to the fourth plug column 8 one by one. When the first plug column 5 is inserted through the vertical steel sleeve 3, the frame beam 2 and the frame column 1, the worker can rotate the first plug column 5 so that the socket 52 is vertically set, and then the fourth plug column 8 can be inserted through the horizontal steel sleeve 4 and the frame beam 2 and inserted into the socket 52, so that the first plug column 5 and the fourth plug column 8 are connected as a whole, thereby improving the connection stability of the beam-column node.

[0037] like Figure 2 and Figure 3 As shown, an embedding groove 323 is provided at one end of the first positioning tube 32 away from the frame column 1, and the embedding groove 323 is arranged in a polygonal shape. A pressing plate 51 which can be slidably embedded in the embedding groove 323 is installed on the first plug column 5. When the first plug column 5 is inserted through the vertical steel sleeve 3, the frame beam 2 and the frame column 1, the pressing plate 51 can be embedded in the embedding groove 323, and at this time, the insertion hole 52 will be arranged vertically so that the fourth plug column 8 can be inserted into the insertion hole 52.

[0038] In this embodiment, the embedding groove 323 is rectangular and not square, so when the pressing plate 51 is embedded in the embedding groove 323 , the insertion hole 52 must be vertically arranged so that the fourth insertion column 8 can be inserted into the insertion hole 52 .

[0039] like Figure 4 and Figure 5 As shown, one end of one of the fourth plug posts 8 is connected to a sharp cone 82 through a connecting rod 81, and a spike 83 is installed on the side wall of the connecting rod 81 between the sharp cone 82 and the fourth plug post 8; one end of the other fourth plug post 8 is provided with a receiving groove 84 for the sharp cone 82 and the spike 83 to be inserted in sequence, and a plastic bag 85 is fixedly installed in the receiving groove 84, and the plastic bag 85 is filled with metal glue 86. When the two fourth plug posts 8 are inserted into the corresponding insertion holes 52, the two fourth plug posts 8 will be butted, the sharp cone 82 and the spike 83 will be pressed against the plastic bag 85 in turn, the sharp cone 82 will pierce the plastic bag 85, and the spike 83 will expand the rupture of the plastic bag 85, so that the metal glue 86 in the plastic bag 85 will flow out, and the metal glue 86 will bond and fix the two fourth plug posts 8 together, thereby improving the connection stability of the beam-column node.

[0040] like Figure 4 As shown, a pressing ring 87 is fixedly sleeved on the fourth plug post 8. When the two fourth plug posts 8 are docked, the pressing ring 87 will be pressed tightly against the end of the fourth positioning tube 44, thereby limiting the position of the fourth plug post 8. When the two fourth plug posts 8 are bonded together, the two pressing rings 87 will be pressed tightly against the corresponding fourth positioning tube 44, so that the two fourth plug posts 8 after bonding and fixing are not prone to shaking.

[0041] like Figure 2 As shown, a second plug column 6 is slidably embedded in the second positioning cylinder 34, and two horizontally arranged second slots 14 are provided on the frame column 1, and the second slots 14 correspond one-to-one to the second plug columns 6; a first pressure plate 61 is installed on the second plug column 6, and an inclined guide plate 62 is installed on the first pressure plate 61.

[0042] A third plug column 7 is slidably embedded in the third positioning cylinder 42 , and vertically arranged third slots 23 are provided on the upper and lower sides of the frame beam 2 , and the third slots 23 correspond one to one with the third plug columns 7 ; a second pressure plate 71 is installed on the third plug column 7 , and a pressure seat 88 is installed on the fourth plug column 8 .

[0043] During the process of the fourth plug column 8 being inserted into the horizontal steel sleeve 4, the frame beam 2 and the first plug column 5, the fourth plug column 8 will first press the guide plate 62 through the pressure seat 88, and the guide plate 62 will drive the second plug column 6 to penetrate into the second slot 14 through the first pressure plate 61; then the pressure seat 88 will detach from the guide plate 62 and press the first pressure plate 61, and the first pressure plate 61 will drive the second plug column 6 to continue to be inserted into the second slot 14, so that the vertical steel sleeve 3 and the frame column 1 are connected as a whole; thereafter, the pressure seat 88 will press the second pressure plate 71 while contacting the first pressure plate 61, and the second pressure plate 71 will drive the third plug column 7 to be inserted into the third slot 23, so that the horizontal steel sleeve 4 and the frame beam 2 are connected as a whole; that is, by pressing the fourth plug column 8, the assembly of the second plug column 6, the third plug column 7 and the fourth plug column 8 can be completed at the same time.

[0044] like Figure 4 and Figure 6 As shown, a first pin 63 is installed on the first pressure plate 61, and a first pin groove 343 is provided on the second positioning tube 34. Before the pressure seat 88 contacts the guide plate 62, the first pin 63 will be partially inserted into the first pin groove 343, and the friction between the first pin 63 and the first pin groove 343 will keep the second plug 6 stable in the second positioning tube 34; therefore, after the second positioning tube 34 is inserted into the second positioning groove 12, the guide plate 62 will be located on the movement track of the pressure seat 88, ensuring that the pressure seat 88 can accurately press the guide plate 62, so as to ensure that the pressure seat 88 can press the second plug 6 into the second slot 14 through the guide plate 62 and the first pressure plate 61; when the second plug 6 is inserted into the second slot 14, the first pressure plate 61 will be pressed tightly against the end of the second positioning tube 34, and the first pin 63 will be completely inserted into the first pin groove 343, so that the second plug 6 and the second positioning tube 34 are connected as a whole.

[0045] like Figure 4 and Figure 7 As shown, the second pressure plate 71 is provided with a second insertion pin 72, and the third positioning cylinder 42 is provided with a second pin groove 423. Before the pressure seat 88 contacts the second pressure plate 71, the second insertion pin 72 will be partially inserted into the second pin groove 423, and the friction between the second insertion pin 72 and the second pin groove 423 will keep the third insertion column 7 stable in the third positioning cylinder 42; therefore, after the third positioning cylinder 42 is inserted into the third positioning groove 21, the second pressure plate 71 will be located on the movement trajectory of the pressure plate 88, ensuring that the pressure plate 88 can accurately press the second pressure plate 71, so as to ensure that the pressure plate 88 can press the third insertion column 7 into the third insertion slot 23 through the second pressure plate 71; when the third insertion column 7 is inserted into the third insertion slot 23, the second pressure plate 71 will be pressed tightly against the end of the third positioning cylinder 42, and the second insertion pin 72 will be fully inserted into the second pin groove 423, so that the third insertion column 7 and the third positioning cylinder 42 are connected as a whole.

[0046] The implementation principle of the assembled concrete beam-column node connection device of the embodiment of the present application is as follows: during the connection process of the beam-column node, the vertical steel sleeve 3 will be slidably sleeved on the frame column 1 from top to bottom until the first positioning cylinder 32 is inserted into the first positioning groove 11, and the second positioning cylinder 34 is inserted into the second positioning groove 12; then the worker will insert the frame beam 2 into the horizontal steel sleeve 4 and cause the frame beam 2 to dock with the frame column 1, at which time the third positioning cylinder 42 will be inserted into the third positioning groove 21, and the fourth positioning cylinder 44 will be inserted into the fourth positioning groove 22; then the worker The first plug 5 will be inserted into the first positioning tube 32, the first slot 13 and the fifth slot 25 in sequence, and the pressure plate 51 will be embedded in the embedding groove 323. At this time, the socket 52 will be vertically arranged. After that, the worker will press down the fourth plug 8 on the upper side and push up the fourth plug 8 on the lower side, so that the two fourth plugs 8 are inserted into the fourth positioning tube 44 and the fourth slot 24 in sequence and complete the docking. The sharp cone 82 and the spike 83 will successively pierce the plastic bag 85, and the metal glue 86 in the plastic bag 85 will flow out and bond the two fourth plugs 8 together.

[0047] During the docking process of the two fourth pins 8, the fourth pin 8 will first press the guide plate 62 and then press the first pressure seat 88 and the second pressure seat 88 through the pressure seat 88, the second pin 6 will be inserted into the second slot 14, and the third pin 7 will be inserted into the third slot 23.

[0048] To sum up, workers only need to complete the connection between the first plug-in column 5 and the fourth plug-in column 8 to complete the assembly of the first plug-in column 5, the second plug-in column 6, the third plug-in column 7 and the fourth plug-in column 8 at one time, so that the vertical steel sleeve 3, the horizontal steel sleeve 4, the frame beam 2 and the frame column 1 are connected as a whole, thereby improving the connection efficiency of the prefabricated beam-column node; in addition, the vertical steel sleeve 3, the horizontal steel sleeve 4 and the pressure seat 88 will together form a triangular structure, thereby preventing the vertical steel sleeve 3 and the horizontal steel sleeve 4 from being easily bent, thereby improving the connection stability of the prefabricated beam-column node.

[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
