Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated buildings, and in particular to a connection structure and method of prefabricated structures suitable for marine engineering. Background Art

[0002] Prefabricated buildings refer to buildings that transfer a large amount of on-site work in traditional construction methods to factories, where building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in the factory, transported to the construction site, and assembled and installed on site through reliable connection methods.

[0003] Most of the vertical prefabricated components of existing assembled concrete structures for marine engineering are connected by grouting sleeves and sleeve grouting. During the promotion and application process, it was found that both steel sleeves and cast iron sleeves have their own corrosion problems. The rust in the inner cavity of the sleeve causes the sleeve grouting material poured into the sleeve during assembly to adhere to the rust on the inner wall of the sleeve instead of the sleeve body. When the force of the steel bar is transmitted to the solidified slurry, the rust bonded by the slurry and the sleeve body loosen and peel off, which seriously affects the force transmission between the grouting material and the sleeve. Some rust develops very rapidly, seriously affecting the quality of the grouting sleeve joint, and may even endanger the overall safety of the structure, while causing a waste of sleeve resources.

[0019] The present invention also discloses a connection method of a prefabricated structure suitable for marine engineering, using a connection structure of a prefabricated structure suitable for marine engineering, comprising the following steps:

[0020] S1: embed the spiral foam and the mounting seat into the casting template, leave holes in the prefabricated building board, and after the casting of the prefabricated building board is completed, use hot air or a softener to soften the spiral foam in the spiral hole and take it out, then dock the two prefabricated building boards so that the mounting hole of one prefabricated building board is aligned with the spiral hole of the other prefabricated building board;

[0021] S2: When two prefabricated building panels are spliced, the rubber gasket at the end of the outer shell of one prefabricated building panel abuts against the other prefabricated building panel, and the rubber gasket fills the gap between the spiral hole and the installation hole;

[0022] The rubber gasket is squeezed and thinned when two prefabricated building panels are butted, and the piercing rod pierces the rubber gasket to cause the caulking adhesive in the cavity to overflow, and the caulking adhesive fills the filling groove formed between the two convex strips, so that the spiral hole and the installation hole are butted and sealed when the two prefabricated building panels are butted;

[0023] S3: Then the staff pours mortar into the prefabricated building board through the grouting port, and the mortar enters the central tube through the grouting port. The moving block in the central tube is pushed by the mortar and moves along the central tube. After the moving block abuts against the baffle at the end of the central tube, the baffle on the moving block is no longer pressed by the inner wall of the central tube. The baffle moves to the outside of the central tube under the elastic force of the elastic telescopic rod, and the moving block is confined in the central tube.

[0024] When the moving block moves, it drives the connecting ribs into the spiral holes of another prefabricated building panel;

[0025] S4: After the stopper moves away from the moving block, the mortar enters the working groove through the slurry passage, and the mortar flowing out of the working groove flows into the mounting hole and the spiral hole. The mortar in the working groove pushes the toggle plate, and the toggle plate drives the rotating rod to rotate. The multiple toggle plates outside the rotating rod rotate synchronously. When the toggle plate rotates, a force is applied to the stopper rod. When the toggle plate no longer abuts against the stopper rod, the connecting rib is reset and rotated under the action of the torsion spring, and the connecting rib swings left and right with the rotating shaft as the center, so that the mortar is fully filled in the mounting hole and the spiral hole;

[0026] Part of the mortar flowing out of the working groove flows into the liquid inlet cavity of the connecting rib, and the mortar in the liquid inlet cavity is discharged from the discharge hole. The discharged mortar pushes the force-bearing sheet, so that the force-bearing sheet outside the rotating ring moves the mortar in the spiral hole circumferentially, and the mortar is fully filled in various places inside the spiral hole, so that the mortar is in close contact with the surface of the connecting rib and the inner wall of the spiral hole;

[0027] S5: As the mortar in the spiral hole continues to increase, the mortar applies thrust to the fan-shaped block on the fixed seat deep in the spiral hole. The fan-shaped block is forced to rotate around the pin shaft, and the fan-shaped block drives the push rod to push the top of the connecting rib, limiting the connecting rib so that the connecting rib is confined in the spiral hole, and the hook at the end of the push rod hooks the hanging hole on the connecting rib, further strengthening the connection between the two prefabricated building panels;

[0028] S6: With the continuous injection of mortar, the fan-shaped block deep in the spiral hole can no longer be pushed. At this time, the grouting work is completed, and the staff seals the grouting port to complete the connection of the two prefabricated building panels.

[0029] Compared with the prior art, the present invention provides a connection structure and method for assembled structures suitable for marine engineering, which has the following beneficial effects:

[0031] 2. The connection structure and method of the prefabricated structure suitable for marine engineering are as follows: a rubber gasket is arranged at the end of the outer shell, and the rubber gasket fills the gap between the spiral hole and the installation hole. The rubber gasket is squeezed and thinned when two prefabricated building panels abut against each other. The puncture rod punctures the rubber gasket and causes the caulking adhesive in the cavity to overflow. The caulking adhesive is filled in the filling groove formed between the two convex strips, so that the spiral hole and the installation hole are butt-sealed when the two prefabricated building panels abut against each other, thereby avoiding overflow during grouting.

[0032] 3. The connection structure and method of the prefabricated structure suitable for marine engineering, wherein the mortar in the working groove pushes the toggle plate, the toggle plate drives the rotating rod to rotate, and multiple toggle plates outside the rotating rod rotate synchronously. When the toggle plate rotates, a force is applied to the baffle rod. When the toggle plate no longer abuts against the baffle rod, the connecting rib is reset and rotated under the action of the torsion spring, and the connecting rib swings left and right with the rotating shaft as the center, so that the mortar is fully filled in the installation hole and the spiral hole, thereby eliminating the grouting gap and improving the connection strength.

[0033] 4. The connection structure and method of the prefabricated structure suitable for marine engineering, part of the mortar flowing out through the working groove flows into the liquid inlet cavity of the connecting rib, and the mortar in the liquid inlet cavity is discharged from the drainage hole. The discharged mortar pushes the force-bearing plate, so that the force-bearing plate outside the rotating ring moves the mortar in the spiral hole circumferentially, and the mortar is fully filled in various places inside the spiral hole, so that the mortar is in close contact with the surface of the connecting rib and the inner wall of the spiral hole, thereby enhancing the connection strength and stability.

[0034] 5.

[0049] Example 1: Reference Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 7 and Fig.10 , a connection structure of an assembled structure suitable for marine engineering, comprising a prefabricated building panel 1, and further comprising:

[0050] A spiral hole 2, which is opened at the end of the prefabricated building board 1, and a spiral foam 201 is arranged in the spiral hole 2;

[0051] A mounting hole 3 is provided at the end of the prefabricated building board 1, a mounting seat 4 is fixedly arranged in the mounting hole 3, and a connecting rib 5 matching with the spiral hole 2 is arranged in the mounting seat 4;

[0052] A toggle mechanism, which is disposed in the mounting seat 4 and is used to drive the connecting rib 5 to shake; and

[0053] The grouting port 6 is provided on the prefabricated building board 1 , and the interior of the mounting seat 4 is communicated with the grouting port 6 .

[0054] Furthermore, the connecting ribs 5 are made of fiber-reinforced plastic (FRP) ribs.

[0055] Specifically, the spiral foam 201 and the mounting seat 4 are embedded in the casting template, and a hole is left in the prefabricated building board 1. After the casting of the prefabricated building board 1 is completed, the spiral foam 201 in the spiral hole 2 is softened and taken out by hot air or a softener, and then the two prefabricated building boards 1 are docked, so that the mounting hole 3 of one prefabricated building board 1 is aligned with the spiral hole 2 of the other prefabricated building board 1, and the staff pours mortar into the prefabricated building board 1 through the grouting port 6, and the mortar enters the mounting seat 4 through the grouting port 6. The slurry automatically drives the toggle mechanism to work and moves the connecting rib 5 into the spiral hole 2. The connecting rib 5 is made of FRP fiber material, which has the advantages of light weight, high tensile strength, strong corrosion resistance, strong material bonding, and strong magnetic wave permeability. When the toggle mechanism is working, it drives the connecting rib 5 to swing left and right in the spiral hole 2. There is no need to use a steel grouting tube, and there will be no problem of failure caused by rust of the grouting tube. It is also more economical and affordable, suitable for the construction of prefabricated buildings in marine engineering, and can achieve the effect of eliminating grouting gaps and high connection strength.

[0056] Example 2: Reference Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 , a connection structure of an assembled structure suitable for marine engineering. On the basis of Example 1, further, the mounting seat 4 includes a central tube 401 fixed in the mounting hole 3 and an outer shell 402 sleeved on the outside of the central tube 401, a moving block 7 is slidably connected in the central tube 401, an elastic element 4011 is arranged between the moving block 7 and the inner wall of the central tube 401, a support plate 8 is fixed to the end of the moving block 7, a rotating shaft 801 is arranged on the support plate 8, an end of the rotating shaft 801 away from the support plate 8 is rotatably connected to the connecting rib 5, and a torsion spring 802 for driving the connecting rib 5 to reset and rotate is sleeved on the outside of the rotating shaft 801.

[0057] Furthermore, a rubber gasket 15 is fixedly provided at the end of the outer shell 402, a plurality of convex strips 151 are provided on the outer side of the rubber gasket 15, a filling groove 152 is formed between two adjacent convex strips 151, a cavity 16 for storing caulking glue is provided in the rubber gasket 15, and a piercing rod 4021 for piercing the rubber gasket 15 is provided at the end of the outer shell 402.

[0058] Furthermore, a baffle 4012 is provided on the top of the central tube 401 and is movably opposed to the moving block 7. The bottom of the moving block 7 is slidably connected to a baffle 9 which is movably opposed to the central tube 401. An elastic telescopic rod 901 is provided between the moving block 7 and the baffle 9. When the end of the moving block 7 is opposed to the baffle 4012, the elastic force of the elastic telescopic rod 901 pushes the baffle 9 away from the moving block 7, and a slurry passage 10 is formed between the baffle 9 and the moving block 7.

[0059] Specifically, when two prefabricated building panels 1 are spliced, the rubber gasket 15 at the end of the outer shell 402 of one prefabricated building panel 1 abuts against the other prefabricated building panel 1, and the rubber gasket 15 fills the gap between the spiral hole 2 and the mounting hole 3. The rubber gasket 15 is squeezed and thinned when the two prefabricated building panels 1 abut against each other, and the piercing rod 4021 contacts and pierces the thinned rubber gasket 15 to cause the caulking glue in the cavity 16 to overflow, and the caulking glue is filled in the filling groove 152 formed between the two convex strips 151, so that the spiral hole 2 and the mounting hole 3 are butt-sealed when the two prefabricated building panels 1 abut against each other, so as to avoid overflow during grouting. The staff pours grout into the prefabricated building panel 1 through the grouting port 6. The mortar material enters the central tube 401 through the grouting port 6. The moving block 7 in the central tube 401 is pushed by the mortar material to move along the central tube 401. After the moving block 7 abuts against the baffle 4012 at the end of the central tube 401, the block 9 on the moving block 7 is no longer pressed by the inner wall of the central tube 401. The block 9 moves toward the outside of the central tube 401 under the elastic force of the elastic telescopic rod 901. The moving block 7 is restricted in the central tube 401. When the moving block 7 moves, it drives the connecting rib 5 to enter the spiral hole 2 of another prefabricated building panel 1. After the block 9 moves away from the moving block 7, the mortar material enters the working groove 11 through the slurry passage 10, and the toggle mechanism automatically drives the connecting rib 5 to swing.

[0060] Example 3: Reference Figure 1 and Figure 2 , a connection structure of an assembled structure suitable for marine engineering, based on Example 2, further, a feed pipe 14 for connecting two adjacent central pipes 401 and for the flow of mortar is fixed in the prefabricated building panel 1.

[0061] Specifically, a feed pipe 14 is arranged between two adjacent center tubes 401. When mortar is injected into one of the center tubes 401 through the grouting port 6, the center tube 401 injects mortar into the other center tube 401 through the feed pipe 14. The operation is simple and convenient, and there is no need to frequently perform grouting work through multiple grouting ports 6, thereby reducing the workload and difficulty of the staff.

[0062] Example 4: Reference Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 and Fig.10 A connection structure of an assembled structure suitable for marine engineering. On the basis of Example 3, further, the toggle mechanism includes a working groove 11 opened in the moving block 7, a rotating rod 111 is rotatably connected in the working groove 11, and toggle plates 112 are evenly arranged on the outer side of the rotating rod 111 in a circular shape, and a blocking rod 113 that resists the toggle plate 112 at one end of the connecting rib 5 is fixed.

[0063] Specifically, after the blocking block 9 moves away from the moving block 7, the mortar enters the working groove 11 through the slurry passage 10, and the mortar flowing out of the working groove 11 flows in the mounting hole 3 and the spiral hole 2. The mortar in the working groove 11 pushes the toggle plate 112, and the toggle plate 112 drives the rotating rod 111 to rotate. The multiple toggle plates 112 outside the rotating rod 111 rotate synchronously, and the toggle plate 112 applies a force to the blocking rod 113 when rotating. When the toggle plate 112 no longer abuts against the blocking rod 113, the connecting rib 5 resets and rotates under the action of the torsion spring 802, and the connecting rib 5 swings left and right with the rotating shaft 801 as the center, so that the mortar is fully filled in the mounting hole 3 and the spiral hole 2, thereby achieving the effect of eliminating the grouting gap and improving the connection strength between the prefabricated building panels 1.

[0064] Example 5: Reference Figure 1 and Fig.11 A connection structure of a prefabricated structure suitable for marine engineering. On the basis of Example 4, further, a liquid inlet cavity 501 is opened in the middle of the connecting rib 5, a plurality of annular grooves 502 are opened on the outer side of the connecting rib 5, and a liquid discharge hole 503 connected to the liquid inlet cavity 501 is opened on the annular groove 502. A rotating ring 12 is rotatably connected in each annular groove 502, and a plurality of force-bearing plates 121 are circumferentially arranged on the rotating ring 12.

[0065] Specifically, part of the mortar flowing out of the working groove 11 flows into the liquid inlet cavity 501 of the connecting rib 5, and the mortar in the liquid inlet cavity 501 is discharged from the drainage hole 503. The discharged mortar pushes the force-bearing plate 121, so that the force-bearing plate 121 on the outside of the rotating ring 12 moves the mortar in the spiral hole 2 circumferentially, further making the mortar fully fill all places inside the spiral hole 2, so that the mortar is in close contact with the surface of the connecting rib 5 and the inner wall of the spiral hole 2, thereby enhancing the connection strength and stability between the prefabricated building panels 1.

[0066] Example 6: Reference Figure 1 , Figure 2 , Figure 4 and Figure 6, a connection structure of an assembled structure suitable for marine engineering. On the basis of Example 5, further, a fixing seat 13 connected to the spiral foam 201 is fixed in the spiral hole 2, and a fan-shaped block 131 is rotatably connected to the fixing seat 13 through a pin shaft. A push rod 132 that is movably opposed to the connecting rib 5 is fixed at one end of the fan-shaped block 131, and a hook 133 is provided at the end of the push rod 132. A hanging hole 504 that matches the hook 133 is opened on the connecting rib 5.

[0067] Specifically, as the mortar in the spiral hole 2 continues to increase, the mortar applies a thrust to the fan-shaped block 131 on the fixed seat 13 deep in the spiral hole 2. The fan-shaped block 131 is subjected to the force to rotate around the pin shaft, and the fan-shaped block 131 drives the push rod 132 to push the top of the connecting rib 5, limit the connecting rib 5, so that the connecting rib 5 is restricted in the spiral hole 2 to prevent the connecting rib 5 from shaking, and the hook 133 at the end of the push rod 132 is hooked on the hanging hole 504 on the connecting rib 5 to further strengthen the connection between the two prefabricated building panels 1. As the mortar is continuously injected, the fan-shaped block 131 deep in the spiral hole 2 can no longer be pushed. At this time, the grouting work is completed, and the staff seals the grouting port 6 to complete the connection work of the two prefabricated building panels 1.

[0068] The present invention also discloses a connection method of a prefabricated structure suitable for marine engineering, using a connection structure of a prefabricated structure suitable for marine engineering, comprising the following steps:

[0069] S1: pre-embed the spiral foam 201 and the mounting seat 4 into the casting template, and leave a hole in the prefabricated building board 1. After the casting of the prefabricated building board 1 is completed, the spiral foam 201 in the spiral hole 2 is softened and taken out by hot air or a softener, and then the two prefabricated building boards 1 are butt-jointed, so that the mounting hole 3 of one prefabricated building board 1 is aligned with the spiral hole 2 of the other prefabricated building board 1;

[0070] S2: When two prefabricated building panels 1 are spliced, the rubber gasket 15 at the end of the outer shell 402 of one prefabricated building panel 1 abuts against the other prefabricated building panel 1, and the rubber gasket 15 fills the gap between the spiral hole 2 and the installation hole 3;

[0071] The rubber gasket 15 is squeezed and thinned when the two prefabricated building panels 1 are butted, and the piercing rod 4021 pierces the rubber gasket 15 to cause the caulking adhesive in the cavity 16 to overflow, and the caulking adhesive fills the filling groove 152 formed between the two convex strips 151, so that the spiral hole 2 and the installation hole 3 are butted and sealed when the two prefabricated building panels 1 are butted;

[0072] S3: Then the staff pours mortar into the prefabricated building board 1 through the grouting port 6, and the mortar enters the central tube 401 through the grouting port 6. The moving block 7 in the central tube 401 is pushed by the mortar and moves along the central tube 401. After the moving block 7 abuts against the baffle 4012 at the end of the central tube 401, the stopper 9 on the moving block 7 is no longer pressed by the inner wall of the central tube 401. The stopper 9 moves to the outside of the central tube 401 under the elastic force of the elastic telescopic rod 901, and the moving block 7 is confined in the central tube 401.

[0073] When the moving block 7 moves, it drives the connecting rib 5 to enter the spiral hole 2 of another prefabricated building panel 1;

[0074] S4: After the stopper 9 is away from the moving block 7, the mortar enters the working groove 11 through the slurry passage 10, and the mortar flowing out of the working groove 11 flows into the mounting hole 3 and the spiral hole 2. The mortar in the working groove 11 pushes the toggle plate 112, and the toggle plate 112 drives the rotating rod 111 to rotate. The multiple toggle plates 112 outside the rotating rod 111 rotate synchronously, and the toggle plate 112 applies a force to the blocking rod 113 when rotating. When the toggle plate 112 no longer abuts against the blocking rod 113, the connecting rib 5 resets and rotates under the action of the torsion spring 802, and the connecting rib 5 swings left and right with the rotating shaft 801 as the center, so that the mortar is fully filled in the mounting hole 3 and the spiral hole 2;

[0075] Part of the mortar material flowing out of the working groove 11 flows into the liquid inlet cavity 501 of the connecting rib 5, and the mortar material in the liquid inlet cavity 501 is discharged from the discharge hole 503. The discharged mortar material pushes the force-bearing sheet 121, so that the force-bearing sheet 121 outside the rotating ring 12 moves the mortar material in the spiral hole 2 circumferentially, and the mortar material is fully filled in various places inside the spiral hole 2, so that the mortar material is in close contact with the surface of the connecting rib 5 and the inner wall of the spiral hole 2;

[0076] S5: As the mortar material in the spiral hole 2 continues to increase, the mortar material applies a thrust to the fan-shaped block 131 on the fixed seat 13 deep in the spiral hole 2. The fan-shaped block 131 is forced to rotate around the pin shaft, and the fan-shaped block 131 drives the push rod 132 to push the top of the connecting rib 5, limiting the connecting rib 5 so that the connecting rib 5 is confined in the spiral hole 2, and the hook 133 at the end of the push rod 132 hooks the hanging hole 504 on the connecting rib 5, further strengthening the connection between the two prefabricated building panels 1;

After the casting of the prefabricated building board (1), use hot air or a softener to soften the spiral foam (201) in the spiral hole (2) and take it out. Then, dock the two prefabricated building boards (1) so that the mounting hole (3) of one prefabricated building board (1) is aligned with the spiral hole (2) of the other prefabricated building board (1); S2: When two prefabricated building panels (1) are spliced ​​together, the rubber gasket (15) at the end of the outer shell (402) of one prefabricated building panel (1) abuts against the other prefabricated building panel (1), and the rubber gasket (15) fills the gap between the spiral hole (2) and the installation hole (3); The rubber gasket (15) is squeezed and thinned when two prefabricated building panels (1) are in contact with each other, and the piercing rod (4021) pierces the rubber gasket (15) to cause the caulking adhesive in the cavity (16) to overflow, and the caulking adhesive is filled in the filling groove (152) formed between the two convex strips (151), so that the spiral hole (2) and the installation hole (3) are butted and sealed when the two prefabricated building panels (1) are in contact with each other; S3: Subsequently, the staff pours mortar into the prefabricated building board (1) through the grouting port (6), and the mortar enters the central tube (401) through the grouting port (6). The moving block (7) in the central tube (401) is pushed by the mortar and moves along the central tube (401). After the moving block (7) abuts against the baffle (4012) at the end of the central tube (401), the baffle (9) on the moving block (7) is no longer pressed by the inner wall of the central tube (401). The baffle (9) moves toward the outside of the central tube (401) under the elastic force of the elastic telescopic rod (901), and the moving block (7) is confined in the central tube (401); When the moving block (7) moves, it drives the connecting rib (5) to enter the spiral hole (2) of another prefabricated building panel (1); S4: After the stopper (9) moves away from the moving block (7), the mortar enters the working groove (11) through the slurry passage (10), and the mortar flowing out of the working groove (11) flows into the mounting hole (3) and the spiral hole (2). The mortar in the working groove (11) pushes the toggle plate (112), and the toggle plate (112) drives the rotating rod (111) to rotate. The multiple toggle plates (112) outside the rotating rod (111) rotate synchronously. When the toggle plate (112) rotates, it applies a force to the stopper (113). When the toggle plate (112) no longer abuts against the stopper (113), the connecting rib (5) resets and rotates under the action of the torsion spring (802), and the connecting rib (5) swings left and right with the rotating shaft (801) as the center, so that the mortar is fully filled in the mounting hole (3) and the spiral hole (2); Part of the mortar material flowing out of the working groove (11) flows into the liquid inlet cavity (501) of the connecting rib (5), and the mortar material in the liquid inlet cavity (501) is discharged from the liquid discharge hole (503). The discharged mortar material pushes the force-bearing plate (121), so that the force-bearing plate (121) outside the rotating ring (12) moves the mortar material in the spiral hole (2) in a circumferential direction, and the mortar material fully fills all places inside the spiral hole (2), so that the mortar material is in close contact with the surface of the connecting rib (5) and the inner wall of the spiral hole (2); S5: As the mortar material in the spiral hole (2) continues to increase, the mortar material applies a thrust to the fan-shaped block (131) on the fixed seat (13) deep in the spiral hole (2), and the fan-shaped block (131) is forced to rotate around the pin shaft, and the fan-shaped block (131) drives the push rod (132) to push the top of the connecting rib (5), limiting the connecting rib (5) so that the connecting rib (5) is restricted in the spiral hole (2), and the hook (133) at the end of the push rod (132) hooks the hanging hole (504) on the connecting rib (5), further strengthening the connection between the two prefabricated building panels (1); S6: As the mortar is continuously injected, the fan-shaped block (131) deep in the spiral hole (2) can no longer be pushed. At this time, the grouting work is completed, and the staff seals the grouting port (6) to complete the connection work of the two prefabricated building panels (1).
