[0057] The following is combined with Figure 1-8 This application is described in further detail.

[0058] The present application embodiment discloses an assembled prefabricated beam. Figure 1The assembled prefabricated beam includes a crossbeam 1 and a template block 22. The crossbeam 1 is a long square column structure, and the template block 22 is an "L" shaped structure. There are two template blocks 22, which are fixedly installed on the vertical side walls opposite to each other on both sides of the length direction of the crossbeam 1 by fixing bolts. When the crossbeam 1 is installed, it is hoisted to the top of the column at the construction site by a lifting device, so that the bottom of the crossbeam 1 and the part close to the end and the bottom of the template block 22 are respectively abutted against the end surface of the top of the column. In the embodiment of the present application, when assembling and fixing, the two crossbeams 1 are used in coordination with each other, so that the two crossbeams 1 are respectively abutted against the top of the column, and the template blocks 22 on the two crossbeams 1 are abutted against each other, so that the template blocks 22 of the two crossbeams 1 are mutually coordinated to surround and form a casting space 221. The protruding steel bar section reserved on the column is located in the casting space 221, and before pouring concrete, a steel cage needs to be supported in the casting space 221 to increase the strength of the two crossbeams 1 and the column connection node.

[0059] Since the beam 1 is usually prefabricated in a factory, there is a certain distance between the beam 1 and the construction site, and it needs to be transported to the construction site first. The beam 1 usually has a certain length and weight. During transportation, there are certain requirements for the lifting and transportation equipment of the beam 1. At the same time, at the construction site, there are certain requirements for the lifting settings and hoisting space of the beam 1. This leads to the fact that during the entire transportation and installation process of the beam 1, in order to reduce the possibility of conflict between the beam 1 and external fixed buildings, the speed of hoisting and moving the beam 1 needs to be slowed down. At this time, the entire assembly construction of the beam 1 takes a long time.

[0060] See also Figure 2 and Figure 3 In order to shorten the entire assembly construction time of the crossbeam 1, the crossbeam 1 includes a plurality of beam bodies 2. The beam bodies 2 are long square columnar structures. The beam bodies 2 are evenly arranged along the length direction, and adjacent beam bodies 2 abut against each other. The assembled prefabricated beam also includes a connecting column 3 and a fixing column 4. The connecting column 3 is embedded and fixed in the beam body 2. The length direction of the connecting column 3 is parallel to the length direction of the beam body 2, and the connecting column 3 protrudes out of the beam body 2 toward the column. A connecting groove 21 is formed on the side of the beam body 2 away from the column. When adjacent beam bodies 2 abut against each other, the connecting column 3 is inserted into the connecting groove 21 of the beam body 2 on the side close to the column, and there is a gap between the peripheral outer wall of the connecting column 3 and the peripheral groove wall of the connecting groove 21.

[0061] The bottom of the fixed column 4 is fixedly connected with a plurality of support columns 41, and the support columns 41 are embedded and fixed to the column, so that the fixed column 4 is located in the middle of the top of the column, and the fixed column 4 is a long square column structure, and the length direction of the fixed column 4 is parallel to the length direction of the connecting column 3 and is on the same straight line. When the cross beam 1 is placed against the top of the column, the fixed column 4 is located between two opposite cross beams 1. A plug-in groove 42 is formed on the side of the fixed column 4 facing the cross beam 1. When the cross beam 1 is placed against the top of the column until the relative template blocks 22 are abutted against each other, the connecting column 3 of the beam body 2 close to the column is inserted into the plug-in groove 42.

[0062] The fixed column 4 is provided with a limiting component 5. When the template blocks 22 of the relative cross beam 1 abut against each other, the connecting column 3 of the beam body 2 close to the column is inserted into the plug-in slot 42. At this time, the limiting component 5 limits the connecting column 3 from being separated from the plug-in slot 42. The limiting component 5 includes limiting teeth 51 and sliding teeth 52. The limiting teeth 51 have two groups and are fixedly installed on the peripheral groove wall of the plug-in slot 42 symmetrically from top to bottom. Each group of limiting teeth 51 has multiple and are evenly arranged along the length direction. The sliding teeth 52 are symmetrically arranged and fixedly installed on the outer wall of the connecting column 3. When the connecting column 3 is inserted into the plug-in slot 42, the sliding teeth 52 are slidably connected to the limiting teeth 51. When the connecting column 3 is subjected to a force applied toward the outside of the plug-in slot 42, the limiting teeth 51 unidirectionally limit the sliding teeth 52, reducing the possibility of the connecting column 3 sliding toward the outside of the plug-in slot 42. In the embodiment of the present application, the vertical cross-section of the limiting teeth 51 and the sliding teeth 52 is a right triangle structure, and the limiting teeth 51 and the sliding teeth 52 are made of steel material with a certain elastic deformation ability.

[0063] An input pipe 31 and an output pipe 32 are fixedly connected in the connecting column 3, and the lengths of the input pipe 31 and the output pipe 32 are equal to the length of the connecting column 3. The connecting column 3, the input pipe 31 and the output pipe 32 are parallel to each other, and the input pipe 31 is located above the output pipe 32.

[0064] See also Figure 3 and Figure 4, an input groove 43 extending along the length direction is formed in the fixed column 4, and the input groove 43 is respectively connected to the opposite input pipes 31 of the adjacent beam bodies 2 on both sides. A grouting port 431 is formed in the middle position of the top outer wall of the fixed column 4, and the grouting port 431 is connected to the input groove 43. The fixed column 4 is connected to a spacer 47, and the spacer 47 is located at the middle position of the bottom of the input groove 43. The spacer 47 separates the input groove 43. When in use, the grouting pipe of concrete is inserted into the grouting port 431, and the concrete is poured into the input groove 43 through the grouting port 431. At this time, the spacer 47 divides the concrete into two parts, which flow to the input pipes 31 on both sides respectively, so that the concrete flows into the input pipes 31. An upper connecting hole 23 is formed in the beam body 2. When the connecting column 3 is inserted into the connecting groove 21, the upper connecting hole 23 connects the two adjacent input pipes 31, and the concrete flows to the next adjacent input pipe 31 through the upper connecting hole 23 until it flows into the input pipe 31 away from the fixed column 4.

[0065] A return pipe 25 is fixedly installed in the beam body 2 away from the fixed column 4. The return pipe 25 is in a "C" shape. The two ends of the return pipe 25 are respectively connected to the input pipe 31 and the output pipe 32 on one side away from the fixed column 4. After the concrete flows into the input pipe 31 away from the fixed column 4, it flows into the output pipe 32 below through the return pipe 25. A lower connecting hole 24 is formed in the beam body 2. When the connecting column 3 is inserted into the connecting groove 21, the lower connecting hole 24 connects two adjacent output pipes 32. After the concrete flows into the output pipe 32 through the return pipe 25, it flows to the next adjacent output pipe 32 in the direction close to the fixed column 4 through the lower connecting hole 24 until it flows into the output pipe 32 close to the fixed column 4.

[0066] See also Figure 1 and Figure 3 An output groove 44 is formed in the fixed column 4, and the output groove 44 is respectively connected to the relative output pipes 32 of the adjacent beam bodies 2 on both sides. A slurry outlet 441 is formed in the middle position of the outer wall at the bottom of the fixed column 4, and the slurry outlet 441 is connected to the output groove 44. The concrete in the output pipe 32 near the fixed column 4 flows into the output groove 44, and finally flows into the casting space 221 through the slurry outlet 441, so that a connection node is achieved between the two relative beams 1 and the columns.

[0067] See also Figure 3 and Figure 4The assembled prefabricated beam also includes a baffle 26, which is fixed around the end of the beam body 2 away from the fixed column 4, and the baffle 26 is in a "U" shape. A partition groove 27 is formed on the side of the beam body 2 away from the baffle 26. When adjacent beam bodies 2 abut against each other, the baffle 26 is inserted into the partition groove 27 to improve the connection strength of the two connected beam bodies 2. An upper grout groove 28 is formed on the side of the beam body 2 close to the fixed column 4. The upper grout groove 28 extends downward along a stepped trajectory. The upper grout groove 28 is connected to the upper connecting hole 23 and the partition groove 27 respectively. A lower grout groove 29 is formed on the side of the beam body 2 close to the fixed column 4. The lower grout groove 29 extends upward along a stepped trajectory. The lower grout groove 29 is connected to the lower connecting hole 24 and the partition groove 27 respectively. When concrete flows into the upper connecting hole 23 and the lower connecting hole 24, the concrete flows into the upper grout groove 28 and the lower grout groove 29 respectively. When the concrete solidifies, the connection strength between the adjacent beam bodies 2 is improved.

[0068] See also Figure 5 The outer walls of the input pipe 31 and the output pipe 32 are respectively fixed with mounting blocks 33, and the mounting blocks 33 are located in the connecting column 3. The mounting blocks 33 are provided with mounting grooves 331, which penetrate the walls of the input pipe 31 and the output pipe 32 respectively. The mounting blocks 33 are rotatably connected with mounting shafts 34, which pass through the mounting grooves 331 and are perpendicular to the connecting column 3. The outer peripheral side of the mounting shaft 34 is fixedly connected with power blades 341, and there are multiple power blades 341, which are evenly spaced along the circumferential direction.

[0069] See also Figure 6 and Figure 7 A movable groove extending in a direction perpendicular to the length of the connecting column 3 is formed on the groove wall of the connecting groove 21, and there are two movable grooves corresponding to the mounting blocks 33. The connecting column 3 is provided with a connecting block 211, which is slidably connected in the movable groove, and the connecting block 211 is inclined toward one side of the notch of the connecting groove 21 to form a connecting surface 2111.

[0070] The beam body 2 is provided with a connecting spring 212, which is located in the moving groove, one end of the connecting spring 212 abuts against the connecting block 211, and the other end abuts against the groove wall on one side of the groove opening of the moving groove. When the connecting spring 212 is elastically released, it pushes the connecting block 211 to protrude into the connecting groove 21.

[0071] A push block 35 is slidably connected to the outer peripheral side of the connection column 3, and the push block 35 corresponds to the connection block 211. When the connection column 3 is inserted into the connection groove 21, the push block 35 slides on the connection surface 2111, and pushes the connection block 211 into the movable groove, until the push block 35 passes the connection block 211, and the connection spring 212 pushes the connection block 211 to protrude into the connection groove 21, at which time the push block 35 is located on the side of the connection block 211 close to the fixed column 4 and abuts against it.

[0072] See also Figure 5 and Figure 7 The beam body 2 is provided with a transmission assembly 6. When the concrete passes through the input pipe 31 and the output pipe 32, the power blade 341 drives the installation shaft 34 to rotate. At this time, the transmission assembly 6 drives the push block 35 to push the connection block 211 toward the notch side of the connection groove 21, thereby improving the tightness between the two adjacent beam bodies 2 and reducing the possibility of concrete leakage. When the beam body 2 provided with the template block 22 is suspended to the top of the column, the connection column 3 of the beam body 2 for installing the template block 22 is first inserted into the insertion groove 42, and then the beam body 2 is rotated so that the push block 35 is on the horizontal plane, so that the push block 35 abuts against one of the steel bar segments reserved for the column close to the fixed column 4 (the fixed column 4 is at Figure 6 The side marked in the middle improves the tightness between the template blocks 22 during concrete grouting and reduces the possibility of concrete leakage in the pouring space 221. After that, the template blocks 22 can be installed and fixed.

[0073] The transmission assembly 6 includes a transmission screw 61, a transmission worm wheel 62 and a transmission worm 63. The transmission worm 63 is coaxially arranged and fixedly connected with the installation shaft 34. The transmission worm 63 is rotatably connected in the connecting column 3. The transmission screw 61 is rotatably connected in the connecting column 3, and the push block 35 is threadedly connected to the transmission screw 61. The transmission worm wheel 62 is fixedly connected to the end of the transmission screw 61, and the transmission worm wheel 62 is rotatably connected in the connecting column 3. The transmission worm wheel 62 is meshed with the transmission worm 63 and meets the self-locking coefficient. When concrete passes through the input pipe 31 and the output pipe 32, the concrete impacts on the power blade 341, driving the installation shaft 34 to rotate. At this time, the transmission worm 63 is linked with the installation shaft 34, driving the transmission worm wheel 62 to rotate, and then the transmission screw 61 rotates with the transmission worm wheel 62, so that the push block 35 moves toward the notch direction of the connecting groove 21.

[0074] See also Figure 3 The bottom of the fixed column 4 is rotatably connected with a transmission pipe 45, which is connected to the slurry outlet 441, and the bottom of the transmission pipe 45 is closed. A slurry outlet pipe 46 is fixedly connected to the outer peripheral side of the transmission pipe 45, and there are multiple slurry outlet pipes 46 that are evenly spaced along the circumferential direction, and the slurry outlet pipes 46 and the transmission pipe 45 are connected to each other. Concrete flows into the transmission pipe 45 from the slurry outlet 441, and then is sprayed to the peripheral side wall position of the pouring space 221 through the slurry outlet pipe 46, which is conducive to improving the uniformity of concrete pouring.

[0075] See also Figure 3 A partition plate 321 is fixedly connected in the fixed column 4. When in use, the partition plate 321 divides the output slot 44 into an upper output area 322 and a lower output area 323. A power plate 324 is slidably connected to the inner wall of the output slot 44. The power plate 324 is located in the lower output area 323, and there is a gap between the power plate 324 and the partition plate 321.

[0076] The fixed column 4 is provided with a power assembly 7. When the power plate 324 slides, the power assembly 7 drives the transmission tube 45 to rotate. The power assembly 7 includes a power rope 71 and a power coil spring 72. A receiving groove surrounding the transmission tube 45 is formed on the side wall of the slurry outlet 441. The power coil spring 72 is sleeved on the outer peripheral side of the transmission tube 45. The power coil spring 72 is located in the receiving groove. One end of the power coil spring 72 is clamped on the outer wall of the transmission tube 45, and the other end is clamped on the fixed column 4. The power rope 71 is slidably passed through the fixed column 4. The power rope 71 is wound around the outer peripheral side of the transmission tube 45. One end of the power rope 71 is fixedly connected to the transmission tube 45, and the other end is fixedly connected to the side of the power plate 324 away from the fixed column 4. When the power plate 324 is close to the fixed column 4, the power ropes 71 on both sides of the fixed column 4 cooperate with each other and pull the transmission tube 45 to rotate at the same time. At this time, the power coil spring 72 enters a contraction state. When concrete flows into the output tube 32 on the side close to the fixed column 4, part of the concrete flows into the upper output area 322, and the other part flows into the lower output area 323. At this time, the concrete pushes the power plate 324 to move toward the fixed column 4, so that the power plate 324 pulls the power rope 71. At this time, the transmission tube 45 releases the power rope 71, and the power coil spring 72 enters an elastic contraction state, while the transmission tube 45 enters a rotation state. On the one hand, the spraying coverage of the concrete is improved, and on the other hand, the transmission tube 45 drives the slurry outlet tube 46 to rotate, stirs the concrete, and improves the uniformity of the concrete in the pouring space 221.

[0077] A blocking plate 325 is slidably connected in the connecting column 3 (the blocking plate 325 is Figure 8 The output pipe 32 is provided with a control component 8 (the control component 8 is Figure 8 ), when the power plate 324 approaches the blocking plate 325, the control component 8 controls the blocking plate 325 to open the lower output area 323. When the power plate 324 approaches the transmission pipe 45, the control component 8 controls the blocking plate 325 to block the lower output area 323. At this time, the power spring elasticity is released, driving the transmission pipe 45 to rotate, winding the power rope 71, and driving the power plate 324 to move away from the fixed column 4, and the concrete between the power plate 324 and the blocking plate 325 passes through the gap between the power plate 324 and the partition plate 321. At the same time, when the partition plate 321 blocks the lower output area 323, the diameter of the slurry outlet 441 for concrete to flow into is reduced, so that the concrete pressure in the beam body 2 is increased, and the area where the concrete has not spread in the beam body 2 is reduced.

[0078] See also Figure 8 The control assembly 8 includes a first control rope 81, a second control rope 82, a first control block 83 and a second control block 84. The first control block 83 and the second control block 84 are respectively slidably connected to the output pipe 32 (the power plate 324 is in Figure 3The first control block 83 and the second control block 84 are located in the lower output area 323. The power plate 324 is located between the first control block 83 and the second control block 84, and the first control block 83 is located on the side of the power plate 324 away from the fixed column 4.

[0079] The first control rope 81 and the second control rope 82 are respectively slidably arranged through the output pipe 32 (the power plate 324 is Figure 3 One end of the first control rope 81 is fixedly connected to the first control block 83 on the side close to the fixed column 4, and the other end is fixedly connected to the blocking plate 325. One end of the second control rope 82 is fixedly connected to the second control block 84 on the side away from the fixed column 4, and the other end is fixedly connected to the side wall of the blocking plate 325 on the side away from the connection point of the first control rope 81.

[0080] When the power plate 324 slides close to the fixed column 4, the power plate 324 first abuts the second control block 84, and then pushes the second control block 84 close to the fixed column 4. At this time, the second control rope 82 pulls the blocking plate 325 to block the lower output area 323. When the power plate 324 slides close to the blocking plate 325, the power plate 324 first abuts the first control block 83, and then pushes the first control block 83 close to the blocking plate 325. At this time, the first control rope 81 pulls the blocking plate 325 to open the lower output area 323.

[0081] The implementation principle of an assembled prefabricated beam in the embodiment of the present application is as follows: the crossbeam 1 includes a plurality of beam bodies 2, which reduces the space requirements during transportation and hoisting. When the beam body 2 is transported to the construction site, the beam body 2 for installing the template block 22 is first hoisted to the top of the column, and then the beam body 2 is supported by the bracket, and then the beam bodies 2 are continuously placed one by one against the side of the previous beam body 2 away from the fixed column 4, and the connecting column 3 is inserted into the connecting groove 21 of the previous adjacent body. After that, the concrete grouting pipe is inserted into the grouting port 431, and then concrete is poured until the concrete flowing out of the grouting port 441 fills the pouring space 221, and finally the template block 22 is removed after the concrete solidifies.

[0082] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
