Technical Field

[0001] The invention relates to the technical field of connection between an assembled prefabricated foundation column and a main body column, in particular to a connection node between a fully assembled prefabricated foundation column and a fully assembled main body. Background Art

[0002] Prefabricated concrete buildings refer to concrete structures that are designed and constructed mainly through on-site assembly using factory-produced prefabricated concrete components. They are one of the important directions for the development of my country's building structures. Compared with traditional cast-in-place concrete structures, prefabricated concrete buildings can reduce construction waste and better meet the requirements of green construction such as energy saving, material saving, water saving, environmental protection, and sustainable development; their components can be produced in factories, reducing production costs and improving work efficiency.

[0003] When actually connecting the foundation column and the main column, the connection methods mainly include bolt connection, welding connection, anchor connection, splicing connection and grouting sleeve connection. However, no matter what connection method is used, the foundation column needs to be positioned. After the foundation column is positioned, the main column needs to be hoisted with the help of a hoisting device, and then the main column and the foundation column body are connected using the hoisting device.

[0004] At present, the upper end surface of the foundation column is only provided with steel bars, and the lower end surface of the main column is only provided with insertion grooves adapted to the steel bars. Therefore, when aligning the two, in order to ensure that the steel bars and the insertion grooves are correctly docked, it takes a long time to align them, which will lead to low overall installation efficiency. After the docking is completed, the overall center of gravity will move upward, and the overall stability performance will be reduced. Summary of the invention

[0014] Compared with the prior art, the present invention has the following beneficial effects: By setting the alignment structure, with the cooperation between the docking block and the first alignment groove and the second alignment groove, when docking the main column and the basic column body, no manual point positioning is required, and the docking between the main column and the basic column body can be quickly completed, the installation speed is fast, and the operation is relatively simple; At the same time, by setting the expansion component and the driving component, when the main column and the basic column body are docked, the trigger surface of the main column cooperates with the trigger member to drive the rotating member to rotate, and then the rotating member, under the cooperation of the engaging groove and the protrusion, can drive the sleeve ring to descend, thereby forcing the expansion plate to move to the outside of the base, so that the floor area of ​​the basic column body is increased, thereby improving the stability of the basic column body after being connected with the main column, avoiding the phenomenon of reduced stability due to the increase of the center of gravity after docking, and then avoiding the occurrence of some safety accidents; In the initial state, the expansion plate is retracted into the base, at which time the base occupies the smallest area, making it easy to carry the basic column body.

[0026] In addition, in order to better illustrate the present application, numerous specific details are provided in the specific embodiments below. It should be understood by those skilled in the art that the present application can also be implemented without certain specific details. In some examples, methods, means, and elements well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present application.

[0027] See also Figure 1-Figure 8 In an embodiment of the present invention, a fully assembled prefabricated foundation column and a fully assembled main body connection node includes: Main column 1 and foundation column body 2, for details, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 The basic column body 2 is divided into two parts from top to bottom: an alignment column 201 and a base 202. The cross section of the alignment column 201 is the same as that of the main column 1. An alignment structure is provided between the main column 1 and the basic column body 2. The alignment structure includes an alignment member and a positioning member. The alignment member includes a docking block 4 fixedly provided on the basic column body 2. The docking block 4 includes a first alignment block 402 and a second alignment block 401. The first alignment block 402 and the second alignment block 401 are provided in two groups respectively. The positioning member includes a first alignment groove 102 and a second alignment groove 101 formed on the main column 1 , and the first alignment groove 102 and the second alignment groove 101 are respectively adapted to the first alignment block 402 and the second alignment block 401 ; Preferably, see Figure 1 , Figure 2 , Figure 3 , the first alignment block 402 and the second alignment block 401 are arranged at intervals, and the height of the first alignment block 402 is higher than that of the second alignment block 401. In particular, the upper end surfaces of the first alignment block 402 and the second alignment block 401 facing the axis of the basic column body 2 are arranged as inclined guide surfaces, and the first alignment block 402 and the second alignment block 401 are interlaced; In the initial state, the foundation column body 2 is placed on the horizontal ground. When connecting the main column 1 with the foundation column body 2, the main column 1 needs to be hoisted with the help of a hoisting device, and then the main column 1 and the foundation column body 2 are connected by the hoisting device. At this stage, the upper end surface of the alignment column 201 of the foundation column body 2 is only provided with a steel bar 5, and the lower end surface of the main column 1 is also only provided with an insertion groove 105 adapted to the steel bar 5. Therefore, when performing the alignment operation of the two, in order to ensure that the steel bar 5 and the insertion groove 105 are correctly connected, it takes a long time to align, which will lead to a low overall installation efficiency. In the present invention, the main column 1 is hoisted by means of a hoisting device, and when it is lowered for docking, the first alignment groove 102 of the main column 1 will first contact the first alignment block 402. As the main column 1 descends, the front and rear surfaces of the main column 1 can be kept coplanar with the front and rear surfaces of the alignment column 201 under the cooperation of the two sets of first alignment blocks 402 (combined with Figure 1 ), at this time, the second alignment groove 101 of the main column 1 begins to contact the second alignment block 401, and as the main column 1 continues to descend, the two groups of second alignment blocks 401 can force the left and right sides of the main column 1 to remain coplanar with the left and right sides of the alignment column 201, and then the steel bars 5 on the foundation column body 2 can just dock with the insertion groove 105 opened on the main column 1. Compared with the above method, the present invention does not require manual point positioning during docking. With the help of the cooperation between the docking block 4 and the first alignment groove 102 and the second alignment groove 101, the docking between the main column 1 and the foundation column body 2 can be quickly completed, the installation speed is fast, and the operation is relatively simple.

[0028] See also Figure 5A placement chamber is provided in the basic column body 2, a fixed column 6 is provided in the placement chamber, an expansion component is provided on the fixed column 6, and the expansion component includes a lifting member, the lifting member is connected to the expansion member provided in the placement chamber, and when the lifting member descends along the axial direction of the fixed column 6, the expansion member can be driven to expand outward, thereby expanding the floor area of ​​the basic column body 2; The fixed column 6 is also provided with a driving assembly, which includes a trigger member and a rotating member. When the main column 1 is docked with the base column body 2, the main column 1 can force the trigger member to descend. When the trigger member descends, it can drive the rotating member to rotate relative to the fixed column 6, thereby forcing the lifting member to descend. Preferably, see Figure 3 , Figure 4 A plug-in hole 103 is provided on one side where the main column 1 and the basic column body 2 are connected. When the main column 1 and the basic column body 2 are connected, the fixed column 6 can be just inserted into the plug-in hole 103, and a trigger surface 104 is provided in the plug-in hole 103. During the descending process of the main column 1, the trigger surface 104 can contact the trigger member, thereby forcing the trigger member to descend relative to the fixed column 6, and then drive the rotating member to move, so that the lifting member can drive the extension member to expand outward, expand the floor area of ​​the base 202, thereby improving the stability of the basic column body 2 after the docking is completed.

[0029] For details, please refer to Figure 5 , Figure 6 , Figure 7 , Figure 8 The trigger member includes a lifting cylinder 11 sleeved on the fixed column 6, a protrusion 1102 is fixedly provided on the outer wall of the lifting cylinder 11, and the protrusion 1102 is slidably provided in a groove 601 opened on the outer wall of the fixed column 6; Preferably, see Figure 6 The above-mentioned protrusions 1102 are arranged in two groups equidistantly along the circumferential direction of the lifting cylinder 11, and correspondingly, the grooves 601 are opened in two groups equidistantly around the circumferential direction of the fixing column 6. With the cooperation of the grooves 601 and the protrusions 1102, the lifting cylinder 11 can only be lifted and lowered along the axial direction of the fixing column 6.

[0030] The rotating member comprises a rotating cylinder 10 rotatably mounted in the placement chamber, the rotating cylinder 10 is sleeved on the fixed column 6, and a sleeve 12 is coaxially fixedly arranged on the rotating cylinder 10, and the sleeve 12 is provided with an arc-shaped sliding surface 1201 around its circumferential direction; Furthermore, the lifting member includes a sleeve ring 8 sleeved on the rotating cylinder 10, a protrusion 801 is formed on the inner wall of the sleeve ring 8, and the protrusion 801 is slidably arranged in a fitting groove body opened on the outer wall of the rotating cylinder 10; For details, please refer to Figure 5 , a fixing part 7 is arranged in the above-mentioned placement chamber, the rotating cylinder 10 is rotatably connected with the fixing part 7, and a receiving plate 1101 is coaxially fixedly arranged on one end of the lifting cylinder 11 away from the sleeve 12. In the initial state, the lifting cylinder 11 is away from the fixing part 7, and the receiving plate 1101 is higher than the upper end surface of the basic column body 2. At this time, the protruding column 1103 fixedly arranged on the outer wall of the rotating cylinder 10 is away from the rotating cylinder 10 and contacts the arc-shaped sliding surface 1201. In combination with the above, when the main column 1 and the basic column body 2 are docked, the triggering surface 104 will first contact the receiving plate 1101. With the decline of the main column 1, the triggering surface 104 can force the lifting cylinder 11 to decline along the axial direction of the fixed column 6. During the decline, the contact and extrusion of the protruding column 1103 on the arc-shaped sliding surface 1201 can force the sleeve 12 to rotate clockwise (refer to Figure 6 ), at this time, the sleeve 12 rotating clockwise can force the sleeve ring 8 to descend in the axial direction relative to the fixed column 6 under the cooperation of the engaging groove and the protrusion 801, and then force the extension piece to expand outward, thereby expanding the floor area of ​​the basic column body 2.

[0031] For details, please refer to Figure 7 The engaging groove body includes an arc groove 1002 formed on the outer wall of the rotating cylinder 10, a positioning groove 1001 is provided at one end of the arc groove 1002, and a spiral groove 1003 is provided at the other end; The expansion member comprises an expansion plate 3 slidably arranged on the base column body 2, and four groups of the expansion plates 3 are equidistantly arranged along the circumferential direction of the fixed column 6, and each group of the expansion plates 3 is connected to the rotating cylinder 10 through a hinge rod 9; Preferably, see Figure 1 , Figure 2 , Figure 5 , Figure 8 The expansion plates 3 are arranged in four groups equidistantly along the circumferential direction of the fixed column 6. Slide blocks 301 are fixedly arranged on the left and right sides of each group of the expansion plates 3. The slide blocks 301 are slidably arranged in the slide grooves provided on the base 202. With the cooperation between the slide blocks 301 and the slide grooves, the expansion plates 3 can only slide in the horizontal plane. In combination with the above, in the initial state, the sleeve ring 8 is affected by gravity, so that the protrusion 801 can be stably engaged with the positioning groove 1001. At this time, the expansion plate 3 is retracted in the base 202, and the base 202 has the smallest footprint, which is convenient for carrying the basic column body 2; When the basic column body 2 is positioned, the main column 1 is hoisted with the help of a hoisting device, and the main column 1 is aligned with the alignment column 201 by using the cooperation between the docking block 4 and the first alignment block 402 and the second alignment block 401. In the subsequent descending process, the trigger surface 104 can push the lifting cylinder 11 to descend along the axial direction of the fixed column 6. Then, the protruding column 1103 cooperates with the arc-shaped sliding surface 1201 to force the sleeve 12 to rotate clockwise (refer to Figure 6 ), during the clockwise rotation of the sleeve 12, the protrusion 801 will first disengage from the positioning groove 1001, and as the sleeve 12 continues to rotate, the protrusion 801 will now slide in the arc groove 1002 until the protrusion 801 is combined with the spiral groove 1003. The rotating sleeve 12 can cause the groove wall of the spiral groove 1003 to squeeze the protrusion 801, thereby forcing the sleeve ring 8 to descend along the axial direction of the fixed column 6. At this time, under the connection action of the fixed-length hinge rod 9, the descending sleeve ring 8 can push the expansion plate 3 toward the outside of the base 202, causing the floor area of ​​the basic column body 2 to increase, thereby improving the stability of the basic column body 2 after being connected to the main column 1, avoiding the phenomenon of reduced stability due to the increase in the center of gravity after docking, and thus avoiding the occurrence of some safety accidents.
