Description

Technical Field

[0001] This application relates to the technical field of prefabricated buildings, and particularly to a grouting connection node for prefabricated components and its construction process. Background Art

[0002] Currently, during the construction of prefabricated components such as prefabricated walls, grouting is often used for installation. That is, steel bars extending upward from the construction base surface are embedded in the lower component, and grouting sleeves are embedded at the bottom of the upper component to be installed. After the installation of the lower component is completed, when installing the upper component, the upper component is hoisted so that the upper component moves to the position where the grouting sleeve is sleeved downward on the steel bars of the lower component, and then grouting is carried out into the grouting sleeve. After the slurry solidifies, the connection between the upper component and the lower component is completed.

[0003] Among them, when grouting the grouting sleeve, usually a grouting machine is used to send slurry to the slurry inlet hole located on the lower side of the grouting sleeve. After the slurry overflows from the slurry outlet hole located on the upper side of the grouting sleeve, rubber plugs are used to block the slurry outlet hole and the slurry inlet hole. This method is prone to the situation of incomplete grouting, making it difficult to control the connection quality between the steel bar and the grouting sleeve. Summary of the Invention

[0004] In order to improve the connection quality of the component connection node, this application provides a grouting connection node for prefabricated components and its construction process.

[0005] In a first aspect, this application provides a grouting connection node for prefabricated components, adopting the following technical solution:

[0006] A grouting connection node for prefabricated components includes: an upper component, a lower component, an end baffle, and a side baffle; the upper component includes an upper component main body and upper longitudinal bars, and the upper longitudinal bars are located in the upper component main body and extend downward from the upper component main body; the lower component includes a lower component main body and sleeves, and the sleeves are embedded at the top of the lower component main body, and the number and positions of the sleeves correspond one-to-one to the upper longitudinal bars; the end baffle and the side baffle jointly enclose a grouting area communicating with the sleeves, and both the end baffle and the side baffle are detachably connected to the construction base surface;

[0007] The grouting area and the sleeves are filled with slurry; the upper component main body is located above the lower component main body, the bottom of the upper component main body is embedded in the grouting area and abuts against the slurry, the bottom of the upper longitudinal bars is inserted into the corresponding sleeves, and there is a leveling gap between the bottom surface of the upper component main body and the top surface of the lower component main body. The upper component main body has an overflow channel communicating the bottom surface of itself with the external environment on the side surface of itself;

[0008] The side baffle has a first state and a second state. The first state is characterized in that the side baffle blocks the leveling gap, and at the same time, the opening of the overflow channel on the side of the upper member body is exposed to the external environment; the second state is characterized in that the side baffle blocks both the leveling gap and the opening of the overflow channel on the side of the upper member body.

[0009] By adopting the above technical solution, first, a grouting area is enclosed by the side baffle and the end baffle, and grout is poured into the grouting area so that the grout can flow into and fill the sleeve by itself. Then, the upper member is hoisted in place. The side baffle and the end baffle prevent the grout between the upper member body and the lower member body from escaping, and the overflow channel allows the excess grout to overflow through the upper member body, improving the uniformity and flatness of grouting and facilitating the hoisting of the upper member to the set elevation. And during the downward movement of the upper member in the grouting area, a downward pressure can be exerted on the grout to assist the grout in filling the sleeve. In the above way, the fullness of the grout in the sleeve can be improved, and the connection quality of the component connection node can be improved. In addition, by adjusting the state of the side baffle, the opening of the overflow channel can be blocked at the same time after the upper member is hoisted, so that the grout solidifies and blocks in the overflow channel.

[0010] Optionally, the lower member further includes lower longitudinal bars fixed in the lower member body. The lower longitudinal bars correspond to the sleeves one by one and extend into the corresponding sleeves, and the upper longitudinal bars and the lower longitudinal bars in the same sleeve are coaxial.

[0011] By adopting the above technical solution, the lower longitudinal bars extending into the sleeve can enhance the structural strength of the sleeve and the grouting connection node.

[0012] Optionally, the overflow channel includes a transverse grout guiding groove and a longitudinal grout guiding groove. The transverse grout guiding groove penetrates through the opposite sides of the upper member body in the horizontal direction, and the longitudinal grout guiding groove penetrates through the bottom surface of the upper member body and the middle part of the transverse grout guiding groove in the vertical direction.

[0013] By adopting the above technical solution, during the process that the upper member body contacts the grout and moves downward, the grout is pressed into the transverse grout guiding groove through the longitudinal grout guiding groove and then flows out from the transverse grout guiding groove to discharge the excess grout in the grouting area.

[0014] Optionally, the side baffle includes a baffle edge group and a positioning seat. The positioning seat is detachably connected to the construction base surface, and the baffle edge group is arranged on one side of the positioning seat facing the grouting area;

[0015] The retaining edge group includes a first retaining edge, a second retaining edge, and a third retaining edge; the first retaining edge abuts against the construction base surface, and the top surface of the first retaining edge is higher than the bottom surface of the upper member body. The second retaining edge moves up and down above the first retaining edge, and there is an adjusting assembly between the first retaining edge and the second retaining edge for adjusting the position of the second retaining edge. One side of the third retaining edge is hinged to the side of the second retaining edge away from the grouting area, and a supporting assembly for supporting the third retaining edge is vertically adjusted and moved on the positioning seat.

[0016] When the side baffle is in the first state, the first retaining edge faces the leveling gap, the second retaining edge is lower than the notch of the transverse grouting groove, and at the same time, the side of the third retaining edge away from the second retaining edge is higher than the notch of the transverse grouting groove. When the side baffle is in the second state, the first retaining edge faces the leveling gap, the second retaining edge abuts against the outer wall of the upper member body and blocks the notch of the transverse grouting groove, and at the same time, the side of the third retaining edge away from the second retaining edge is lower than the side of the third retaining edge close to the second retaining edge.

[0017] By adopting the above technical solutions, by adjusting the positions of the second retaining edge and the third retaining edge, effective shielding of the leveling gap and the opening of the overflow channel is achieved.

[0018] Optionally, the adjusting assembly includes

[0019] An extension seat, which is arranged on the side of the first retaining edge away from the grouting area;

[0021] A locking head, which is vertically threadedly sleeved on the threaded member and is used to abut against the upper and lower sides of the extension seat to relatively position the extension seat and the threaded member.

[0022] By adopting the above technical solutions, by adjusting the height position of the locking head on the threaded member, the height of the second retaining edge is adjusted so that the second retaining edge can adapt to the height of the transverse grouting groove.

[0023] Optionally, the supporting assembly includes

[0024] A support column, which slides vertically in the positioning seat;

[0025] A rotating column, which is rotatably connected in the positioning seat, one end extends out of the side of the positioning seat away from the grouting area, and the rotation axis of the rotating column is perpendicular to the support column;

[0026] The first bevel gear is rotatably connected to the positioning seat and coaxially sleeved on the outer wall of the support column by threads; and

[0027] The second bevel gear is fixedly sleeved on the rotating column and meshes with the first bevel gear at the same time.

[0028] By adopting the above technical solution, the rotating column is rotated to drive the second bevel gear to rotate, thereby driving the first bevel gear to rotate, and further enabling the support column to move up and down relative to the first bevel gear.

[0029] Optionally, the side baffle further includes a top edge and a guide rod; the top edge is located directly above the first baffle edge and extends along the length direction of the first baffle edge; the guide rod is connected to the top edge, and the guide rod penetrates downward through the second baffle edge and extends into the first baffle edge;

[0030] There is a linkage assembly between the hinge shaft of the third baffle edge and the guide rod. When the third baffle edge rotates, the guide rod is driven to move up and down through the linkage assembly, and when the third baffle edge is positioned relative to the second baffle edge, the guide rod is positioned relative to the first baffle edge;

[0031] When the side baffle is in the first state, the bottom surface of the top edge is lower than the highest point of the third baffle edge; when the side baffle is in the second state, the bottom surface of the top edge can abut against the top surface of the second baffle edge.

[0032] By adopting the above technical solution, when the third baffle edge rotates, it drives the top edge to move up and down, so that when the baffle edge group receives the slurry in the first state, by driving the third baffle edge to swing back and forth to drive the slurry to shake, and at the same time the top edge applies a downward pressure to the slurry to assist the slurry to flow into the overflow channel to fill the overflow channel.

[0033] Optionally, the guide rod includes a linkage section and a driving section connected in sequence from top to bottom; the linkage section is rotatably connected to the top edge, the outer periphery of the linkage section is evenly spaced with linkage teeth along its circumferential direction, the second baffle edge has a perforation for the linkage section to pass through, and a corrugated sleeve is connected between the top of the second baffle edge and the top edge, and the corrugated sleeve encloses the linkage section between the second baffle edge and the top edge; the driving section extends vertically into the first baffle edge, and the driving section is inclined with a stroke groove along its circumferential direction, and a stroke projection abutted against the stroke groove is fixed on the first baffle edge;

[0034] The linkage assembly includes a first gear, a second gear, a third gear, a main bevel gear, and a sub-bevel gear; the first gear is coaxially and fixedly sleeved on the hinge shaft of the third gear edge; the second gear is rotatably connected in the second gear edge and is coaxially fixed with the main bevel gear, the third gear is rotatably connected in the second gear edge and is coaxially fixed with the sub-bevel gear, and the axis of the second gear is perpendicular to the axis of the third gear, the main bevel gear meshes with the sub-bevel gear, and at the same time the third gear meshes with the linkage tooth.

[0035] By adopting the above technical solution, through the cooperation of the linkage section and the linkage assembly, and the cooperation of the driving section and the first gear edge, the linkage between the third gear edge and the guide rod is realized.

[0036] Optionally, the sleeve has a guiding cylinder extending upward from the sleeve, which is used to extend the slurry to indicate the position of the upper longitudinal reinforcement of the upper member.

[0037] By adopting the above technical solution, the guiding cylinder extends out of the slurry so as to visually indicate the position of the upper longitudinal reinforcement, which is convenient for alignment and installation during construction and improves construction efficiency.

[0038] In a second aspect, the present application provides a construction process for a grouting connection node of a prefabricated member, adopting the following technical solution:

[0040] Step 1: The upper member, the lower member, the end stop, and the side stop are respectively manufactured and completed;

[0041] Step 2: Enclose the end stop and the side stop around the circumference of the lower member main body, so as to form a grouting area communicating with the inner cavity of the sleeve above the lower member main body;

[0042] Step 3: Adjust the side stop to the first state, and then pour the slurry into the grouting area. The slurry flows into the sleeve under its own gravity and gradually accumulates in the grouting area, and the slurry in the grouting area is higher than the design elevation of the bottom surface of the upper member main body;

[0045] Step 6: After the slurry reaches a certain strength, remove the end stop, the side stop, and the lifting structure of the upper member.

[0046] In summary, the present application includes at least one of the following beneficial effects:

[0047] 1. By enclosing a grouting area with the end stop and the side stop, after the slurry flows into the sleeve by itself, there is still slurry above the sleeve, so that the slurry can continuously supplement the sleeve during the process of the upper longitudinal reinforcement extending into the sleeve, improving the fullness of the slurry in the sleeve and significantly improving the connection quality of the grouting connection node;

[0048] 2. The leveling gap enables the upper component to have a space for correction, improving the installation quality of the component;

DETAILED DESCRIPTION

[0065] The following is combined with Figure 1 To Attachment Figure 14 This application is described in further detail.

[0066] Embodiment 1:

[0067] The present application embodiment discloses a prefabricated component grouting connection node. Figure 1 and Figure 2 The prefabricated component grouting connection node includes an upper component 1, a lower component 2, an end stopper 6 and a side stopper 7.

[0068] Reference Figure 1 and Figure 3, the upper member 1 includes an upper member main body 101 and upper longitudinal bars 102. The upper longitudinal bars 102 are embedded in the upper member main body 101 and extend longitudinally. A plurality of upper longitudinal bars 102 are distributed in an array. The bottom of the upper longitudinal bars 102 extends downward out of the upper member main body 101, and the bottom of the upper longitudinal bars 102 extends downward out of the bottom surface of the upper member 1. In this embodiment, the upper member main body 101 is a square wall, and the upper longitudinal bars 102 are steel bars.

[0069] The lower member 2 includes a lower member main body 201, a sleeve 202, and lower longitudinal bars 203. The sleeve 202 is in the shape of a hollow cylinder and is embedded in the top of the lower member main body 201. The top surface of the sleeve 202, the top surface of the lower member main body 201, and the construction base surface for installing the upper member 1 are all flush, and the inner diameter of the sleeve 202 is larger than the outer diameter of the upper longitudinal bars 102. The lower longitudinal bars 203 are embedded in the lower member main body 201 and extend longitudinally. A plurality of lower longitudinal bars 203 are distributed in an array in the lower member 2. At the same time, the lower longitudinal bars 203 correspond to the sleeves 202 one by one. The top of the lower longitudinal bars 203 extends coaxially to the bottom of the corresponding sleeve 202 and is fixed to the sleeve 202. In this embodiment, the lower member main body 201 is a square wall, and the lower longitudinal bars 203 are steel bars. In other embodiments, the lower member main body 201 can also be a floor slab of a transfer floor.

[0070] Refer to Figure 1 and Figure 2 , the end stoppers 6 and the side stoppers 7 are both detachably connected to the construction base surface. The end stoppers 6 are opposite to the ends of the upper member main body 101, and the side stoppers 7 are opposite to the sides of the upper member main body 101. The end stoppers 6 at both ends of the upper member main body 101 jointly clamp the side stoppers 7 on both sides to enclose a grouting area. The inner cavity of the sleeve 202 in the lower member 2 communicates with the grouting area.

[0071] When installing the upper member 1, first install the end stoppers 6 and the side stoppers 7, pour the slurry into the grouting area. The slurry flows into the sleeve 202 by its own gravity to fill the sleeve 202 and accumulates in the grouting area. After the slurry is poured, hoist the upper member 1 to face the grouting area and gradually lower it, so that the upper longitudinal bars 102 gradually extend downward into the corresponding sleeves 202. The upper longitudinal bars 102 and the lower longitudinal bars 203 on the same sleeve 202 are coaxial, and the upper member main body 101 is embedded in the grouting area until the height of the upper member main body 101 reaches the design elevation. A leveling gap 4 filled with slurry is formed between the top surface of the upper member main body 101 and the top surface of the lower member main body 201. Wait for the slurry to solidify to a certain strength and then the end stoppers 6 and the side stoppers 7 can be removed. In this embodiment, the height of the leveling gap 4 is 20 mm.

[0072] Refer to Figure 1 and Figure 3, in order to enable the excess slurry to overflow during the process of lowering and pressing the slurry by the upper component 1, an overflow channel 5 is provided on the upper component main body 101. Specifically, a plurality of overflow channels 5 are evenly spaced along the length direction of the upper component main body 101. In this embodiment, the interval between two adjacent overflow channels 5 is 500 mm. Each overflow channel 5 includes a transverse slurry guiding groove 51 and a longitudinal slurry guiding groove 52. The transverse slurry guiding groove 51 horizontally penetrates through the opposite sides of the upper component main body 101 along the thickness direction of the upper component main body 101, and the longitudinal slurry guiding groove 52 vertically penetrates through the middle of the transverse slurry guiding groove 51 and the bottom surface of the upper component main body 101. During the process of the upper component 1 pressing the slurry downward, the excess slurry enters the upper component main body 101 from the longitudinal slurry guiding groove 52 and overflows to the outside of the upper component main body 101 from the transverse slurry guiding groove 51.

[0073] Refer to Figure 1 , Figure 2 and Figure 4 , specifically, the end stopper 6 is in the shape of a square strip and can be detachably fixed to the construction base surface by ground nails. The side stopper 7 includes a positioning seat 72 and a retaining edge group 71. The positioning seat 72 is detachably connected to the construction base surface by ground nails, and a plurality of positioning seats 72 are arranged on each side of the upper component main body 101 along the length direction of the upper component main body 101. The retaining edge group 71 is detachably connected to the side of the positioning seat 72 facing the grouting area, and the side stopper 7 encloses the grouting area through the retaining edge group 71.

[0074] Refer to Figure 4 and Figure 5 , the retaining edge group 71 includes a first retaining edge 711, a second retaining edge 712 and a third retaining edge 713. The first retaining edge 711 is in the shape of a square long strip, and the extending height of the first retaining edge 711 is greater than the extending height of the leveling gap 4. The second retaining edge 712 is located above the first retaining edge 711 and is connected to the first retaining edge 711 through an adjusting component 8. The second retaining edge 712 is located directly above the first retaining edge 711 and is in the shape of a square long strip. An extension part 18 is fixed to the top of the side of the second retaining edge 712 facing away from the grouting area. The third retaining edge 713 is in the shape of a square long strip, and one side of the third retaining edge 713 is hinged to the side of the second baffle facing away from the grouting area through a hinge shaft. It should be noted that the length extending directions and extending lengths of the first retaining edge 711, the second retaining edge 712, the extension part 18 and the third retaining edge 713 are all the same, and the hinge axis of the third retaining edge 713 is parallel to its own length extending direction.

[0075] Among them, the connection mode between the retaining edge group 71 and the positioning seat 72 is that an installation column 11 extending horizontally and perpendicular to the length direction of the first retaining edge 711 is fixed on one side surface of the first retaining edge 711. The installation column 11 has an external thread. The positioning seat 72 is in a square shape and is slidably sleeved on the installation column 11 along the axis of the installation column 11. And a nut is threadedly connected to the installation column 11, and the nut abuts against one surface of the positioning seat 72 facing away from the first retaining edge 711. It should be noted that the bottom surface of the positioning seat 72 is flush with the bottom surface of the first retaining edge 711, and the top surface of the positioning seat 72 is higher than the top surface of the first retaining edge 711.

[0076] In addition, a support assembly 9 is vertically adjusted and moved on the positioning seat 72. The top end of the support assembly 9 abuts against the bottom surface of the third retaining edge 713 to support the third retaining edge 713. By adjusting the height position of the support assembly 9, the rotation angle of the third retaining edge 713 relative to the second retaining edge 712 can be adjusted. The third retaining edge 713 has a top extreme state and a bottom extreme state relative to itself.

[0077] Refer to Figure 4 , when the third retaining edge 713 is in the top extreme state, the upper surface of the third retaining edge abuts against the side edge of the extension part 18 away from the second retaining edge 712. The extension part 18 prevents the third retaining edge 713 from continuing to rotate upward. At this time, the side of the third retaining edge 713 away from the second retaining edge 712 is higher than the hinged side of the third retaining edge 713.

[0078] Refer to Figure 6 , when the third retaining edge 713 is in the bottom extreme state. The lower surface of the third retaining edge 713 abuts against the side edge of the top of the positioning seat 72 away from the first retaining edge 711. The positioning seat 72 prevents the third retaining edge 713 from continuing to move downward. At this time, the side of the third retaining edge 713 away from the second retaining edge 712 is lower than the hinged side of the third retaining edge 713.

[0079] Refer to Figure 1 and Figure 4 , furthermore, the retaining edge group 71 has a first state and a second state under the combined action of the adjusting assembly 8 and the support assembly 9. Specifically, when the retaining edge group 71 is in the first state, the bottom surface of the first retaining edge 711 abuts against the construction base surface, the bottom surface of the second retaining edge 712 abuts tightly against the top surface of the first retaining edge 711, and the surfaces of the first retaining edge 711 and the second retaining edge 712 facing away from the positioning seat 72 are flush. At the same time, the third retaining edge 713 is in the top extreme position. At this time, the first retaining edge 711, the second retaining edge 712 and the construction base surface jointly enclose a grouting area. Combining Figure 6 , when the retaining edge group 71 is in the second state, the bottom surface of the first retaining edge 711 still abuts against the construction base surface, and the second retaining edge 712 moves upward relative to the first state, creating a gap between the first retaining edge 711 and the second retaining edge 712. At the same time, the third retaining edge 713 is adjusted to the bottom extreme position.

[0080] Before hoisting the upper member 1, the retaining edge group 71 is first adjusted to the first state, and then the slurry is poured into the grouting area. Then, the upper member 1 is hoisted to the design elevation, and the retaining edge group 71 remains in the first state during the hoisting process of the upper member 1. After the hoisting of the upper member 1 is completed, the first retaining edge faces the leveling gap 4, the second retaining edge 712 is lower than the notch of the transverse slurry guiding groove 51, the top surface of the second retaining edge 712 is flush with the lowest point of the notch of the slurry guiding port, and at the same time, the side of the third retaining edge 713 away from the second retaining edge 712 is higher than the topmost end of the notch of the transverse slurry guiding groove 51. The top surface of the second retaining edge 712, the outer side surface of the upper member body 101, and the second retaining edge 712 jointly enclose a storage cavity 12 with an upward opening, and the slurry overflowing from the notch of the transverse slurry guiding groove 51 is stored in the storage cavity 12.

[0081] After the hoisting of the upper member 1 is completed and the slurry overflow is completed, the storage cavity 12 is filled with slurry to make the slurry in the storage cavity 12 higher than the notch of the transverse slurry guiding groove 51, so that the slurry can automatically flow into and fill the transverse slurry guiding groove 51 and the longitudinal slurry guiding groove 52. Subsequently, the retaining edge group 71 is adjusted to the second state. The first retaining edge 711 still maintains the sealing state of the leveling gap 4, while the second retaining edge 712 moves upward to block the notch of the transverse slurry guiding groove 51, and the third retaining edge 713 inclines downward away from the second retaining edge 712 to guide the excess slurry away. The retaining edge group 71 remains in the second state until all the end stoppers 6 and the side stoppers 7 are removed after the slurry reaches the demolding strength. It should be noted that when the retaining edge group 71 is in the first state or the second state, both ends of the third retaining edge 713 away from each other respectively abut against the two end stoppers 6 to prevent the slurry from overflowing from the ends of the third retaining edge 713.

[0082] Refer to Figure 5 As shown in, further, for the adjusting assembly 8, multiple groups of adjusting assemblies 8 are evenly spaced along the length direction of the first retaining edge 711. Each group of adjusting assemblies 8 includes an extension seat 81, a threaded member 82, and a locking head 83. The extension seat 81 is fixed at the top position on the side of the first retaining edge 711 close to the positioning seat 72 and is in a square shape. The threaded member 82 has a threaded section with an axis extending vertically. In this embodiment, the threaded member 82 is a stud fixed to the surface of the second retaining edge 712 facing the positioning seat 72 through a connecting plate, and the threaded member 82 penetrates downward through the extension seat 81. The locking head 83 is in the shape of a nut and two locking heads 83 are provided in each group of adjusting assemblies 8. Both locking heads 83 are threadedly sleeved on the threaded member 82, and the two locking heads 83 respectively abut against the upper and lower sides of the extension seat 81 to position the threaded member 82 relative to the extension seat 81, that is, to relatively position the first retaining edge 711 and the second retaining edge 712. By adjusting the position of the locking head 83, the position of the second retaining edge 712 relative to the first retaining edge 711 can be adjusted.

[0083] Moreover, a displacement blocking head 19 in the shape of a nut is coaxially and fixedly sleeved on the threaded member 82, and the displacement blocking head 19 is located below the two locking heads 83. When the blocking edge group 71 is in the second state, the displacement blocking head 19 and the extension seat 81 jointly clamp the lower locking head 83 among the two locking heads 83. At this time, the distance between the first blocking edge 711 and the second blocking edge 712 is the largest.

[0084] Referring Figure 5 and Figure 7 For the support assembly 9, the support assemblies 9 correspond to the positioning seats 72 one by one. Each support group includes a support column 91, a rotating column 92, a first bevel gear 93, and a second bevel gear 94. The support column 91 is cylindrical and vertically slides in the positioning seat 72, and the top end of the support column 91 extends upward out of the positioning seat 72. A square guide portion 13 is fixed to the bottom of the outer peripheral wall of the support column 91. A guide groove for the vertical sliding of the guide portion 13 is provided in the positioning seat 72 to limit the rotation of the support column 91 in the positioning seat 72. The rotating column 92 is cylindrical and rotates in the positioning seat 72, and the axis of the rotating column 92 is perpendicular to the axis of the support column 91. One end of the rotating column 92 extends out of the positioning seat 72 and is fixed with a handle. The first bevel gear 93 is rotatably connected in the positioning seat 72, and at the same time, the support column 91 coaxially passes through the first bevel gear 93 in a threaded manner. The second bevel gear 94 is coaxially and fixedly sleeved on the rotating column 92 and rotates together with the rotation of the rotating column 92. At the same time, the first bevel gear 93 meshes with the second bevel gear 94. Thus, by rotating the rotating column 92, the second bevel gear 94 drives the first bevel gear 93 to rotate, and further drives the support column 91 to move up and down for adjustment.

[0085] The embodiment of the present application also discloses a construction process for a grouting connection joint of a prefabricated member, including the following steps:

[0086] Step 1: The upper member 1, the lower member 2, the end blocking member 6, and the side blocking member 7 are respectively manufactured, and the construction of the lower member 2 is completed and the top surface is flush with the construction base surface.

[0087] Step 2: Install the end blocking member 6 and the side blocking member 7 on the construction base surface. The inner side surface of the end blocking member 6, the inner side surface of the side blocking member 7, and the top surface of the lower member body 201 jointly enclose a grouting area; then, adjust the blocking edge group 71 to the first state.

[0088] Step 3: Pour the slurry into the grouting area. The slurry flows into the sleeve 202 under its own gravity and gradually accumulates in the grouting area, and the upper surface of the slurry in the grouting area is higher than the designed elevation of the bottom surface of the upper member body 101.

[0089] Step 4: Hoist the upper component 1. First, hoist the upper component 1 above the grouting area and then gradually lower it, so that the upper longitudinal bars 102 extend vertically into the corresponding sleeves 202, and the bottom of the upper component body 101 is gradually embedded vertically into the grouting area until the design elevation is reached. During this process, the retaining edge group 71 remains in the first state; among them, during the process of pressing the slurry on the upper component body 101, the excess slurry flows through the overflow channel 5 into the storage cavity 12 for storage.

[0090] Step 5: Pour slurry into the storage cavity 12 so that the upper surface of the slurry is higher than the highest point of the notch of the transverse slurry guiding groove 51, so that the slurry automatically flows into the overflow channel 5 to fill the overflow channel 5.

[0091] Step 6: Place a material receiving container opposite to the third retaining edge 713 on the construction base surface. Subsequently, adjust and move the retaining edge group 71 to the second state, so that the notch of the transverse slurry guiding groove 51 filled with slurry is blocked by the second retaining edge 712, and at the same time, the excess slurry is guided by the third retaining edge 713 to flow downward and be recycled into the material receiving container.

[0092] Step 7: After the slurry hardens to a certain strength, remove the end retaining member 6, the side retaining member 7, and the hoisting structure for the upper component 1. The slurry surface at the notch of the transverse slurry guiding groove 51 near one end of the upper component body 101 is flush with the outer surface of the upper component body 101.

[0093] Embodiment 2:

[0094] The difference between the embodiment of the present application and Embodiment 1 is that: the side retaining member 7 further includes a top edge 20 and a guide rod 21.

[0095] Specifically, referring to Figure 8 and Figure 9 , the top edge 20 is located directly above the second retaining edge 712. The top edge 20 is in the shape of a long strip extending along the length direction of the second retaining edge 712. At the same time, the side of the top edge 20 close to the grouting area is flush with the side of the second retaining edge 712 close to the grouting area, and the side of the top edge 20 far from the grouting area extends beyond the side of the second retaining edge 712 far from the grouting area in the direction away from the grouting area.

[0096] Referring to Figure 9 and Figure 10, the guide rod 21 is rotatably connected to the top edge 20. A plurality of guide rods 21 are distributed at intervals along the length direction of the top edge 20, and each guide rod 21 vertically penetrates through the second retaining edge 712 and extends into the first retaining edge 711. Specifically, the guide rod 21 includes a linkage section 211 and a driving section 212 fixedly connected in sequence from top to bottom. The outer periphery of the linkage section 211 is evenly spaced with linkage teeth 22, so that any cross-section of the linkage section 211 is in the shape of a spline. The driving section 212 is in the shape of a circular shaft coaxial with the linkage section 211. The outer diameter of the driving section 212 is smaller than the circumferential dimension enclosed by the linkage teeth 22, and a travel groove 24 is inclinedly opened along the circumferential direction of the outer periphery of the driving section 212.

[0097] The second retaining edge 712 is vertically provided with a through hole for the linkage section 211 to pass through, and the first retaining edge 711 is vertically provided with a sliding hole for the driving section 212 to slide. A travel protrusion (not shown in the figure) is fixed on the inner wall of the sliding hole of the first retaining edge 711, and the travel protrusion abuts into the travel groove 24 of the driving section 212. Thus, when the guide rod 21 rotates relative to the top edge 20, it can move up or down simultaneously through the cooperation and guidance of the travel protrusion and the travel groove 24, and then drive the top edge 20 to move up or down together.

[0098] Refer to Figure 8 and Figure 9 , furthermore, the third retaining edge 713 is hinged to the second retaining edge 712, and the hinge shaft of the third retaining edge 713 is fixed to rotate together with the third retaining edge 713. There is a linkage assembly between the hinge shaft of the third retaining edge 713 and the linkage section 211. When the third retaining edge 713 rotates towards the extension part 18, the linkage assembly drives the guide rod 21 and the top rod to move up. Similarly, when the third retaining edge 713 rotates towards the positioning seat 72, the linkage assembly drives the guide rod 21 and the top edge 20 to move down, so that when feeding the overflow channel 5, the shaking of the third retaining edge 713 can assist the flow of the mortar, reduce internal air bubbles, and apply pressure to the slurry between the top edge 20 and the second retaining edge 712 through the downward pressure of the top edge 20 to extrude the residual air, making it easier for the slurry to flow into the overflow channel 5.

[0099] Refer to Figure 9 and Figure 10, specifically, the linkage assembly includes a first gear 25, a second gear 26, a third gear 27, a main bevel gear 28, and a sub-bevel gear 29. The first gear 25 is coaxially and fixedly sleeved on the hinge shaft of the third gear edge 713, and the third gear edge 713 has a cavity for making way for the first gear 25. Both the second gear 26 and the third gear 27 are rotatably connected in the second gear edge 712, and the axis of the second gear 26 is parallel to the axis of the hinge shaft. The second gear 26 is simultaneously meshed with the first gear 25; the axis of the third gear 27 is parallel to the axis of the linkage section 211, and the third gear 27 is simultaneously meshed with the linkage tooth 22. Both the main bevel gear 28 and the sub-bevel gear 29 are rotatably connected in the second gear edge 712, and the main bevel gear 28 is coaxially fixed with the second gear 26 through a rod, and the sub-bevel gear 29 is coaxially fixed with the third gear 27 through a rod. To facilitate the assembly of the linkage assembly and the guide rod 21, both the first gear edge 711 and the second gear edge 712 are formed by splicing.

[0100] When the third gear edge 713 swings relative to the second gear edge 712, the third gear edge 713 drives the first gear 25 to rotate synchronously, thereby sequentially driving the second gear 26, the main bevel gear 28, the sub-bevel gear 29, the third gear 27, and the linkage section 211 to rotate, and further driving the top edge 20 to move vertically.

[0101] Refer to Figure 8 and Figure 10 . To prevent the slurry from leaking from the perforations to between the second gear edge 712 and the first gear edge 711, a corrugated sleeve 23 corresponding to the guide rod 21 is connected between the top surface of the second gear edge 712 and the top edge 20. The corrugated sleeve 23 encloses the linkage section 211 of the corresponding guide rod 21 between the second gear edge 712 and the top edge 20. And the lower surface of the top edge 20 has a receiving cavity for receiving the compressed corrugated sleeve 23.

[0102] Refer to Figure 8 and Figure 10 . Among them, when the gear edge group 71 is in the first state, the bottom surface of the top edge 20 is higher than the notch of the transverse slurry guide groove 51.

[0103] Refer to Figure 9 and Figure 11 , when the second gear edge 712 moves to block the notch of the transverse slurry guide groove 51, and at the same time the movement blocking head 19 and the extension seat 81 jointly clamp the locking head 83, and the third gear edge 713 abuts against the extension part 18, there is a moving space between the bottom surface of the top edge 20 and the top surface of the second gear edge 712. Refer to Figure 12 . In this state, swing the third gear edge 713 downward until it abuts against the positioning seat 72, drive the top edge 20 to move downward until it abuts against the top surface of the second gear edge 712, and compress and receive the corrugated sleeve 23 into the receiving cavity, so that the slurry between the top edge 20 and the second gear edge 712 is extruded and sent to the third gear edge 713 for derivation, so as to improve the slurry feeding efficiency.

[0104] Furthermore, the top surface of the top edge 20 is an inclined surface that gradually slopes downward away from the grouting area, so as to guide part of the slurry flowing to or pressed onto the top surface of the top edge 20 away from the top edge 20.

[0105] Refer to Figure 11 and Figure 12 In addition, a shielding cloth 30 is connected between the extension part 18 and the third retaining edge 713. The shielding cloth 30 extends along the length direction of the third retaining edge 713. The shielding cloth 30 is made of a flexible and elastically stretchable material. When the third retaining edge 713 abuts against the extension part 18, the shielding part is wrinkled. When the third retaining edge 713 is in the second state and abuts against the positioning seat 72, the shielding cloth 30 unfolds. By means of the shielding cloth 30, it is possible to prevent the slurry from leaking to the hinge shaft of the third retaining edge 713 when the third retaining edge 713 swings.

[0106] The embodiment of the present application also discloses a construction process for a grouting connection node of a prefabricated component. The difference from the construction process in Embodiment 1 is as follows:

[0107] In Step 5, pour slurry into the continuous accumulation cavity 12 so that the upper surface of the slurry is higher than the highest point of the notch of the transverse slurry guiding groove 51, and at the same time make the upper surface of the slurry close to the bottom surface of the top edge 20. Adjust the support column 91 downward by a certain distance so that the third retaining edge 713 can swing between the support column 91 and the extension section to shake the slurry, and at the same time apply pressure to the slurry through the top edge 20 to assist the slurry to flow into the overflow channel 5.

[0108] Embodiment 3:

[0109] The difference between the embodiment of the present application and the above embodiment is that: it further includes a guiding cylinder 10.

[0110] Refer to Figure 13 and Figure 14 In this embodiment, the guiding cylinder 10 is arranged in the sleeve 202. Specifically, the guiding cylinder 10 corresponds to the sleeve 202 one by one and is coaxial with the sleeve 202, and the extension height of the guiding cylinder 10 is less than the extension height of the sleeve 202. The guiding cylinder 10 includes a connecting ring 14 and a connecting rod 15. There are two connecting rings 14. The two connecting rings 14 are circular and coaxial, and the inner diameter of the connecting ring 14 is greater than the outer diameter of the upper longitudinal rib 102. The connecting rod 15 is fixedly connected between the two connecting rings 14 and is arranged at intervals along the circumferential direction of the connecting ring 14. A gap for slurry to flow through is formed between adjacent two connecting rods 15, and the extending length direction of the connecting rod 15 is parallel to the axial direction of the connecting ring 14.

[0111] The inner circumference of the sleeve 202 is recessed with a coaxial reinforcing ring 16, and a connecting block 17 extending inward is fixed on the inner wall of the sleeve 202 near the top end. When the connecting rod 15 cooperates with the guiding cylinder 10, the outer wall of the connecting rod 15 abuts against the inner wall of the reinforcing ring 16, and the connecting block 17 extends into the space between two adjacent connecting rods 15 and is connected to the connecting rod 15. At this time, the connecting block 17 is close to the connecting ring 14 at the lower end of the guiding cylinder 10, and the upper part of the guiding cylinder 10 extends upward out of the top of the sleeve 202. It should be noted that the connection method between the connecting rod 15 and the connecting block 17 is a weak connection. For example, it is connected by using a low-strength adhesive or by using low-strength materials such as plastic or aluminum alloy, so that the connection point between the connecting rod 15 and the connecting block 17 is an easily separable point.

[0112] When pouring the slurry into the grouting area, the connecting block 17 and the connecting rod 15 remain connected, and the upper surface of the slurry in the grouting area is lower than the upper surface of the guiding cylinder 10, and the guiding cylinder 10 extends out of the slurry. When hoisting the upper member 1, the upper longitudinal reinforcement 102 is aligned with the guiding cylinder 10 to improve the efficiency of reaching the design position. During the lowering process of the upper member 1, the upper longitudinal reinforcement 102 first extends into the guiding cylinder 10, and then the bottom surface of the upper member body 101 abuts against the guiding cylinder 10. The downward pressure of the upper member body 101 causes the connection point between the connecting rod 15 and the connecting block 17 to fail, and the guiding cylinder 10 moves downward together under the push of the upper member body 101.

[0113] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
