Description

Technical Field

[0001] This application relates to the field of building construction, and in particular to a barrier structure for pouring works. Background Technology

[0002] In cast-in-place concrete frame structures, to meet seismic fortification requirements, a strong column-weak beam design principle is typically adopted, meaning the concrete strength of the beams is lower than that of the columns. Because the concrete strengths of the beams and columns differ, the concrete used for the beams and columns needs to be isolated. After being covered by formwork below the floor slab, a first and a second pouring trench are formed. The first trench is used for pouring horizontal beams, and the second trench is used for pouring vertical columns; the first and second trenches are connected. Both the first and second trenches contain reinforcing cages, which consist of multiple reinforcing bars and stirrups. The multiple reinforcing bars are arranged in a rectangular loop, and then the stirrups are wrapped around and tied to each reinforcing bar.

[0003] Currently, the isolation of beam and column concrete typically uses air-filled barriers. Before pouring the column concrete, multiple air-filled barriers are inserted side-by-side into the first pouring trench for isolation. After inflation, the air-filled barriers are secured within the gaps of the reinforcing cage itself and between the reinforcing cage and the first pouring trench, thus maintaining their stability. Concrete is then poured into the second pouring trench, with some flowing into the first pouring trench and being blocked by the air-filled barriers. After the column concrete has initially set but before it has completely solidified, the air-filled barriers are deflated and removed. After the air-filled barriers are removed, concrete is poured into the second pouring trench. The concrete in the first pouring trench solidifies to form the beam, and the concrete in the second pouring trench solidifies to form the column.

[0004] Regarding the aforementioned technologies, the inventors believe that when the partition airbags are inserted side-by-side into the first pouring groove, they are generally clamped together by two stirrups to keep them fixed and reduce the possibility of displacement due to compression by the concrete. However, after the two stirrups clamp the partition airbags, they will vertically block the concrete, resulting in a smaller contact area between concrete of different strengths, thereby reducing the connection strength between them. Summary of the Invention

[0005] In order to improve the connection strength between concretes of different strengths, this application provides a barrier structure for pouring projects.

[0006] This application provides a barrier structure for pouring concrete, which adopts the following technical solution:

[0007] A barrier structure for pouring concrete includes two opposing first side plates and two opposing second side plates. A support plate is rotatably mounted between the two first side plates. The support plate has a clamping opening and multiple barrier airbags. The barrier airbags pass through the clamping opening. A support rod is fixedly mounted between the two second side plates. The support rod has multiple first pressure rods, each corresponding to a barrier airbag. A first sleeve is threaded onto each first pressure rod. A first pressure block is mounted on one end of each first pressure rod. One end of each barrier airbag is clamped by the clamping opening, and the other end is pressed by the first pressure block. The first sleeve abuts against the support rod.

[0008] By adopting the above technical solution, the deflating airbags become soft, and then multiple airbags are tilted and placed into the first pouring groove. The rotating support plate is adjusted according to the tilt of the airbags, and then one end of each airbag passes through the clamping opening. Each airbag is inflated, and after expansion, the clamping opening clamps one end of the airbag, causing adjacent airbags to press against each other, thus acting as a barrier. Then, the first pressure block presses against the other end of the airbag, and the first sleeve presses against the support rod, thereby keeping the airbags fixed and reducing the possibility of them moving under the pressure of the concrete.

[0009] Next, concrete is poured into the second pouring tank. After the concrete in the second pouring tank has initially set but before it has fully solidified, the air vents are deflated, and then the air vents are removed. After the air vents are removed, concrete is poured into the second pouring tank. After the concrete in the first pouring tank solidifies, it forms the beams, and after the concrete in the second pouring tank solidifies, it forms the columns.

[0010] By setting the airbags at an angle, the contact area between the concrete in the first and second pouring troughs is increased, thereby improving the connection strength between concretes of different strengths.

[0011] Optionally, the end of the first sleeve away from the first pressure block is sealed, and a pressure groove is provided at the end of the first sleeve away from the first pressure block, with the inner wall of the pressure groove tightly abutting against the body of the support rod.

[0012] By adopting the above technical solution, when the first sleeve is pressed against the support rod, the support rod enters the inside of the pressure groove, and the rod body of the support rod is engaged with the inner wall of the pressure groove, thereby reducing the occurrence of movement after the first sleeve and the support rod are squeezed against each other.

[0013] Optionally, the opposite side walls of the pressure groove are inclined, and the distance between the two side walls of the pressure groove gradually decreases from the groove opening to the groove bottom. The inner wall of the pressure groove and the body of the support rod both have anti-slip textures.

[0014] By adopting the above technical solution, the support rod may accumulate dust, thus increasing its diameter. The inclined sides of the pressure groove facilitate the support rod's entry into the groove. Simultaneously, wear during use reduces the support rod's diameter, and the inclined sides of the pressure groove further ensure the support rod's body abuts against the inner walls of the groove.

[0015] Optionally, the support plate is provided with a second pressure rod, a second sleeve, and a second pressure block. The second sleeve is installed on the support plate, the second pressure rod is threaded through the second sleeve, and the second pressure block is located inside the clamping opening. The second pressure block is fixedly connected to one end of the second pressure rod, and the second pressure block is used to compress the airbag.

[0016] By adopting the above technical solution, the diameter of the baffle airbag is set according to the gap between two adjacent steel bars, and different sizes of baffle airbags are used for beams of different sizes. When it is necessary to clamp the baffle airbag, the second pressure rod is rotated to drive the second pressure block to extend and press against the baffle airbag, thereby facilitating the clamping of baffle airbags of different diameters inside the clamping opening.

[0017] Optionally, the side wall of the support plate is provided with a sliding opening, which is connected to the clamping opening. The second sleeve of each clamping opening is slidably disposed in the sliding opening. A limit block is fixedly installed on the outer wall of the second sleeve, and a groove is provided on the inner wall of the sliding opening for the limit block to slide.

[0018] By adopting the above technical solution, the support sleeve slides inside the sliding opening, which facilitates the alignment of the first pressure block with the partition airbag, and thus facilitates the first pressure block to press the partition airbag. When the first pressure block presses the partition airbag, the limiting block abuts against the inner wall of the sliding groove, thereby restricting the sliding of the second sleeve inside the sliding opening.

[0019] Optionally, a connecting rod is provided between the first side plate and the second side plate, and both the first side plate and the second side plate are provided with sliding holes for the connecting rod to slide through.

[0020] By adopting the above technical solution, the connecting rod passes through the sliding hole, thus facilitating the adjustment of the distance between the first and second side plates. When the partition airbag is inserted into the first pouring groove, the partition airbag is compressed by the concrete, and the bottom end of the partition airbag is located inside the first pouring groove. This causes the bottom end of the partition airbag to exert an upward thrust on the first pressure block, and the first pressure block exerts an upward thrust on the support rod through the first pressure rod and the first sleeve. The first and second side plates are connected together by the connecting rod, so that the weight of the first side plate is applied to the second side plate, thereby reducing the possibility of the support rod causing the two second side plates to move upward.

[0021] Optionally, a counterweight is placed inside the airbag, and the side of the first pressure block away from the first pressure rod has a magnetic force, which is used to attract the counterweight.

[0022] By adopting the above technical solution, when the airbag is tilted and placed into the first pouring trench, the airbag is not inflated and remains in a soft state. The first pressure block attracts the counterweight, facilitating the adjustment of the airbag's position to avoid the reinforcing cage before tilting it into the first pouring trench. When the first pressure block presses down on the airbag, the counterweight and the first pressure block attract each other, reducing the possibility of relative sliding between them. Simultaneously, the counterweight increases the weight at the bottom of the airbag, reducing the likelihood of it warping under the pressure of the concrete.

[0023] Optionally, rotating rods are fixedly installed on both sides of the support plate. The rotating rods are rotatably inserted into the first side plate. A square rod is provided on the opposite side of each of the two first side plates. One end of the square rod is fixedly connected to the end of the rotating rod away from the support plate. The square rod is provided with a sliding plate. The sliding plate has a square opening for the square rod to slide through. A limit rod is fixedly installed on the side of the sliding plate near the first side plate. The first side plate has multiple limit holes for the limit rod to be damped and inserted. The limit holes are arranged around the rotating rod.

[0024] By adopting the above technical solution, after the airbag passes through the clamping opening and is clamped, the sliding plate is pushed to move towards the first side plate, allowing the limiting rod to insert into the limiting hole. The limiting rod engages with the inner wall of the limiting hole, thus restricting the rotation of the support plate. By restricting the rotation of the support plate, the possibility of the top of the airbag moving when subjected to concrete pressure is reduced. Simultaneously, when the airbag passes through the clamping opening, the limiting rod and the limiting hole may not be aligned on the side of the airbag perpendicular to the support plate. Rotating the support plate aligns the limiting rod with the limiting hole, thereby further clamping the airbag within the clamping opening.

[0025] Optionally, a first limiting plate is fixedly installed at the end of the square rod away from the rotating rod. The first limiting plate is used to restrict the sliding plate from sliding down from the end of the square rod away from the rotating rod. A spring is sleeved on the square rod, and the spring is fixedly installed on the first limiting plate. The spring is used to push the sliding plate to move towards the first side plate.

[0026] By adopting the above technical solution, the spring pushes the sliding plate to move towards the first side plate, thereby reducing the occurrence of automatic sliding due to vibration of the sliding plate, and thus making it easier for the limit rod to remain inserted into the limit hole.

[0027] Optionally, a second limiting plate is hinged to the periphery of the first limiting plate. The second limiting plate is L-shaped and is used to hook the sliding plate.

[0028] By adopting the above technical solution, when it is necessary to rotate the support plate, the second limiting plate hooks onto the sliding plate, and the sliding plate drives the limiting rod to be pulled out from the limiting hole, thereby facilitating the rotation of the support plate.

[0029] In summary, this application includes at least one of the following beneficial technical effects:

[0030] After the partition airbag is inserted into the first pouring groove at an angle, the top of the partition airbag is clamped inside the clamping port. After the first sleeve presses against the support rod, the first pressure rod presses the bottom of the partition airbag through the first pressure block, so that the partition is kept tilted to block the concrete. The contact surface between the concrete of different strengths between the beam and the column is an inclined surface, thereby improving the connection strength between concrete of different strengths.

[0031] The second sleeve slides inside the sliding opening to align the second pressure block with the partition airbag. Then, the second pressure rod is rotated, which moves the second pressure block to press the partition airbag, thus facilitating the clamping of partition airbags of different diameters in the clamping opening.

Detailed Implementation

[0042] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0043] This application discloses a barrier structure for pouring concrete.

[0044] Reference Figure 1 , Figure 2 The floor slab is covered by formwork, which, together with the floor slab, forms a first pouring groove 1 for casting horizontal beams and a second pouring groove 2 for casting vertical columns. The first pouring groove 1 and the second pouring groove 2 are interconnected. Both the first pouring groove 1 and the second pouring groove 2 contain a reinforcing cage 5, which includes multiple reinforcing bars 51 and stirrups 52. The multiple reinforcing bars 51 are arranged in a rectangular loop, and then the stirrups 52 are fitted onto each reinforcing bar 51 and tied tightly.

[0045] Reference Figure 3 , Figure 4 A barrier structure for pouring concrete includes two opposing first side plates 3. A support plate 6 is disposed between the two first side plates 3.

[0046] Reference Figure 4 , Figure 5 Rotating rods 7 are fixedly installed on both sides of the support plate 6. The rotating rods 7 are rotatably inserted into the first side plate 3, thereby facilitating the rotation of the support plate 6 between the two first side plates 3. The two first side plates 3 support the support plate 6, allowing the support plate 6 to span over the position of the first pouring groove 1 in the floor slab.

[0047] Reference Figure 4 , Figure 5Each of the two first side plates 3 has a square rod 8 on its opposite side. One end of the square rod 8 is fixedly connected to the end of the rotating rod 7 away from the support plate 6, and the other end of the square rod 8 is fixedly installed with a first limiting plate 9. The square rod 8 is provided with a sliding plate 11, which has a square opening 12 for the square rod 8 to slide through. The sliding plate 11 is located between the first limiting plate 9 and the first side plate 3. A limiting rod 13 is fixedly installed on the side of the sliding plate 11 closest to the first side plate 3, and the first side plate 3 has multiple limiting holes 14 for the damping insertion of the limiting rod 13. The multiple limiting holes 14 are arranged around the rotating rod 7.

[0048] Reference Figure 4 , Figure 5 Pull the sliding plate 11 away from the first side plate 3 to move it away, allowing the limiting rod 13 to be pulled out of the limiting hole 14, thus facilitating the rotation of the support plate 6. Push the sliding plate 11 towards the first side plate 3 to allow the limiting rod 13 to be inserted into the limiting hole 14, where it engages with the inner wall of the square opening 12 through the rod body of the square rod 8, thereby restricting the rotation of the support plate 6.

[0049] Reference Figure 4 , Figure 5 A spring 15 is fitted onto the square rod 8, and the spring 15 is fixedly installed on the first limiting plate 9. The spring 15 is used to push the sliding plate 11 to move towards the first side plate 3. A second limiting plate 10 is hinged to the periphery of the first limiting plate 9. The second limiting plate 10 is L-shaped and is used to hook the sliding plate 11. When it is necessary to rotate the support plate 6, the second limiting plate 10 hooks the sliding plate 11, thereby lowering the support plate 6. When rotating the support plate 6, the spring 15 drives the limiting rod 13 to insert into the limiting hole 14 through the sliding plate 11. When it is not necessary to rotate the support plate 6, the second limiting plate 10 releases the sliding plate 11, and the spring 15 drives the sliding plate 11 to move towards the first side plate 3, allowing the limiting rod 13 to insert into the limiting hole 14.

[0050] Reference Figure 3 , Figure 6 The support plate 6 is provided with multiple baffle airbags 16, and the support plate 6 has clamping openings 17 for the baffle airbags 16 to pass through. The baffle airbags 16 are deflated to keep them in a soft state. Then, the baffle airbags 16 are inserted obliquely into the first casting groove 1. After the baffle airbags 16 are inserted obliquely into the first casting groove 1, the top of the baffle airbags 16 passes through the clamping openings 17.

[0051] Reference Figure 6 , Figure 7The support plate 6 has a sliding opening 18 on its side wall, which communicates with the clamping opening 17. A second sleeve 20 is slidably disposed inside the sliding opening 18. A limiting block 25 is fixedly installed on the outer wall of the second sleeve 20, and a sliding groove 26 is provided on the inner wall of the sliding opening 18 for the limiting block 25 to slide. The limiting block 25 and the inner wall of the sliding groove 26 are engaged with each other, thereby reducing the possibility of the second sleeve 20 being pulled out of the sliding opening 18.

[0052] Reference Figure 6 , Figure 7 The second sleeve 20 is threaded with a second pressure rod 22, and a second pressure block 24 is fixedly installed at the end of the second pressure rod 22 facing the inside of the clamping opening 17. After the partition airbag 16 is inserted into the clamping opening 17, the partition airbag 16 is inflated. Then, the second sleeve 20 is moved so that the second pressure block 24 is aligned with the partition airbag 16. Then, the second pressure rod 22 is rotated, and the second pressure rod 22 drives the second pressure block 24 to press the partition airbag 16 tightly, thereby clamping the top of the partition airbag 16 inside the clamping opening 17. By moving the second pressure block 24 closer to or further away from the partition airbag 16 through the second sleeve 20, it is convenient to clamp partition airbags 16 of different diameters inside the clamping opening 17.

[0053] Reference Figure 8 A counterweight 27 is placed inside the partition airbag 16. When the partition airbag 16 is tilted and placed into the first pouring groove 1, the counterweight 27 slides towards the bottom of the partition airbag 16, which helps to press the bottom of the partition airbag 16 tightly and reduces the possibility of the bottom of the partition airbag 16 rotating upward under the pressure of the concrete.

[0054] Reference Figure 3 It also includes two opposing second side plates 4, with a support rod 28 fixedly installed between the two second side plates 4. The two second side plates 4 support the support rod 28, allowing the support rod 28 to pass over the position in the floor slab where the first pouring groove 1 is located.

[0055] Reference Figure 3 , Figure 9 The support rod 28 is provided with multiple first pressure rods 21, each corresponding to a baffle airbag 16. A first sleeve 19 is threaded onto each first pressure rod 21, and a first pressure block 23 is installed at one end of each first pressure rod 21. The first sleeve 19 is used to press against the support rod 28, and the first pressure block 23 is used to press against the baffle airbag 16.

[0056] After the partition airbag 16 is tilted and placed into the first pouring groove 1, the first pressure block 23 is used to press the bottom end of the partition airbag 16, and then the first sleeve 19 is rotated. The first sleeve 19 is pressed tightly against the support rod 28, thereby pressing the bottom end of the partition airbag 16 and reducing the possibility of the bottom end of the partition airbag 16 rotating upward under the pressure of the concrete.

[0057] Reference Figure 8 , Figure 9 The first pressure block 23 has magnetic force and is used to attract the counterweight 27. During the process of tilting the partition airbag 16 into the first pouring groove 1, the first pressure block 23 attracts the counterweight 27. Then, by moving the first pressure rod 21, the partition airbag 16 is moved to avoid the steel cage 5, so that the partition airbag 16 can be tilted into the first pouring groove 1.

[0058] Reference Figure 3 , Figure 9 The end of the first sleeve 19 furthest from the first pressure block 23 is sealed, and a pressure groove 29 is formed at the end of the first sleeve 19 furthest from the first pressure block 23. The inner wall of the pressure groove 29 abuts tightly against the body of the support rod 28. When the first sleeve 19 abuts against the support rod 28, the support rod 28 enters the interior of the pressure groove 29 and engages with the body of the support rod 28 through the inner wall of the pressure groove 29, thereby reducing the possibility of the support rod 28 separating from the first sleeve 19 after relative sliding.

[0059] Reference Figure 3 , Figure 9 The two side walls of the pressure groove 29 are inclined, and the distance between the two side walls of the pressure groove 29 gradually decreases from the groove opening to the bottom of the groove. During use, the support rod 28 may wear or accumulate dust, causing changes in its diameter. The inclination of the two side walls of the pressure groove 29 facilitates the insertion of the support rod 28 into the pressure groove 29, allowing the rod body to press firmly against the two side walls of the pressure groove 29.

[0060] Both the inner wall of the pressure groove 29 and the body of the support rod 28 have anti-slip textures. The anti-slip textures help increase the friction between the inner wall of the pressure groove 29 and the support rod 28, thereby reducing the possibility of the first sleeve 19 slipping along the length of the support rod 28.

[0061] Reference Figure 3 , Figure 9 A connecting rod 30 is provided between the first side plate 3 and the second side plate 4. Both the first side plate 3 and the second side plate 4 have sliding holes 31 for the connecting rod 30 to slide through. The baffle airbag 16 is placed obliquely into the first pouring groove 1, with the top of the baffle airbag 16 outside the first pouring groove 1 and the bottom of the baffle airbag 16 inside the first pouring groove 1. The bottom of the baffle airbag 16 is compressed by the concrete, and the weight of the first side plate 3 is pressed onto the second side plate 4 through the connecting rod 30, thereby reducing the possibility of the bottom of the baffle airbag 16 lifting up due to the compression of the concrete.

[0062] The implementation principle of a baffle structure for pouring engineering according to an embodiment of this application is as follows: The first pressure block 23 moves to one end of the baffle airbag 16, allowing the first pressure block 23 to attract the counterweight block 27. Then, the first pressure block 23 is moved by the first sleeve 19 and the second pressure rod 22, allowing one end of the baffle airbag 16 to be inserted obliquely into the first pouring trough 1. There is a baffle airbag 16 between the reinforcing cage 5 and the side wall of the first pouring trough 1, and there is also a baffle airbag 16 between every two adjacent reinforcing bars 51 on the top side of the reinforcing cage 5. Then, the first pressure block 23 is separated from the counterweight block 27, and the bottom end of the baffle airbag 16 falls into the bottom of the first pouring trough 1 under the pressure of the counterweight block 27.

[0063] After the partition airbag 16 is inserted obliquely into the first casting groove 1, the support plate 6 is rotated so that the top of the partition airbag 16 passes through the clamping port 17, and the partition airbag 16 is inflated. Then the second sleeve 20 is moved so that the second pressure block 24 is aligned with the partition airbag 16, and the second pressure rod 22 is rotated so that the second pressure block 24 presses the partition airbag 16 tightly. The second limiting plate 10 is rotated so that the second limiting plate 10 releases the sliding plate 11. The sliding plate 11 moves towards the first side plate 3 under the action of the spring 15, so that the limiting rod 13 is pressed tightly against the first side plate 3. Then the support plate 6 is rotated, and the support plate 6 drives the sliding plate 11 to rotate through the rotating rod 7 and the square rod 8, so that the limiting rod 13 is aligned with the limiting hole 14, and then the limiting rod 13 is inserted into the limiting hole 14. The limiting rod 13 engages with the inner wall of the limiting hole 14, thereby restricting the rotation of the support plate 6, and the top of the barrier airbag 16 is clamped inside the clamping port 17.

[0064] After the top of the airbag 16 is clamped, the first pressure block 23 is pressed against the bottom of the airbag 16. Then the first pressure block 23 and the counterweight 27 attract each other, thereby reducing the possibility of the first pressure block 23 slipping after pressing against the airbag 16.

[0065] After the first pressure block 23 abuts against the airbag 16, the first sleeve 19 is rotated, and the first sleeve 19 moves towards the support rod 28, so that the support rod 28 enters the pressure groove 29 and abuts tightly against the inner wall of the pressure groove 29. By the support rod 28 abutting tightly against the inner wall of the pressure groove 29, the first pressure block 23 presses the bottom end of the airbag 16.

[0066] Concrete is then poured into the second pouring tank 2, filling it completely. Some of the concrete then flows into the first pouring tank 1, where it is blocked by the air-blocking bladder 16. After the concrete has initially set but before it has fully solidified, the air-blocking bladder 16 is deflated, and then removed, allowing more concrete to be poured into the first pouring tank 1. The contact surfaces of the two different strengths of concrete inside the first pouring tank 1 are inclined due to the influence of the air-blocking bladder 16, thereby increasing the contact area between the two types of concrete and improving the bond strength between them.

[0067] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
