Description

Technical Field

[0001] The present invention relates to the technical field of raft construction, and more specifically, the present invention relates to a special device and method for waterproof construction of a flat raft foundation. Background Art

[0002] A flat raft is based on a large reinforced concrete slab with a vast bottom area, which can effectively reduce the base pressure and enhance the bearing capacity of the foundation soil. It can also significantly enhance the integrity of the foundation, thereby better adjusting possible uneven settlements. During the construction of a flat raft foundation, first, measurement and setting out are carried out, then the foundation pit is excavated, and then the cushion concrete is poured. Subsequently, the brick formwork for the foundation raft is built and waterproof treatment is done. Finally, the steel bars are tied and the raft is poured.

[0003] During the waterproof treatment, waterproof coiled materials need to be laid, and the waterproof coiled materials are turned up and extended out of the raft surface by a certain length. After the laying is completed, the turned-up and extended waterproof part needs to be folded inwards on the top of the brick formwork and a layer of bricks is built on it for protection, with the top surface of the bricks flush with the raft surface.

[0004] Currently, when folding the turned-up part inwards on the top of the brick formwork, only stones are used to press it down after folding the turned-up part inwards, and then a layer of bricks is directly built subsequently. However, after the turned-up part is folded inwards, at the bending position, the material on the inner surface is compressed, and the material on the outer surface is stretched. With greater elasticity, it is easy to bulge. When a layer of bricks is built, it is easy to lift the bricks, and subsequent re-treatment is required. Summary of the Invention

Detailed implementation manners

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] As Figure 13 shown, in the current technology, after the upward-return 301 is folded inward, a layer of bricks 400 is laid. After the upward-return 301 is folded inward, at the bending position, the material on the inner surface is compressed, and the material on the outer surface is stretched. With relatively large elasticity, it is easy to bulge and generate a bulging part 500. When a layer of bricks 400 is laid, the bulging part 500 will lift the bricks 400. Therefore, the following technical solutions are proposed.

[0033] Referring to the attached drawings of the specification Figures 1 - 12, A special device for waterproof construction of a flat raft foundation, including a vehicle body 1. On one side of the vehicle body 1, a support frame 2 is installed. At the front side position of the support frame 2, an upper heating component 3 is installed. A connecting frame 4 is installed on the support frame 2, and a power component 5 is installed on the connecting frame 4. A lower heating component 6 and a folding component 7 are installed on the power component 5. The upper heating component 3 includes a linear driving component one 31 fixedly installed on the support frame 2. The output end of the linear driving component one 31 is installed with a heating component 32. The heating component 32 includes an upper heating pipe 321, and the upper heating pipe 321 is used to heat and soften the folding position on the upper surface of the upward return 301 of the waterproof coiled material 300. The lower heating component 6 includes a lower heating pipe 61, and the lower heating pipe 61 is used to heat and soften the folding position on the lower surface of the upward return 301 of the waterproof coiled material 300. The folding component 7 is used to fold the upward return 301 from the folding position.

[0034] In the above technical solution, before folding the upward return 301 of the waterproof coiled material 300, the upper heating pipe 321 is pressed on the folding position on the upper surface of the upward return 301 of the waterproof coiled material 300 to heat and soften the folding position. The lower heating pipe 61 is pressed on the folding position on the lower surface of the upward return 301 of the waterproof coiled material 300 to heat and soften the folding position. In this way, after the upward return 301 is folded, due to softening, the stress on the inner bending part and the outer bending part of the crease is greatly reduced, and the elasticity is reduced. After softening and hardening, the crease position will not bulge again, so that after laying a layer of bricks, the bricks will not be lifted up.

[0035] In this embodiment, as Figures 4 - 6 shown, the power component 5 includes a main support 51 fixedly installed on the connecting frame 4. A main support 51 and a guide frame one 52 arranged side by side are fixedly connected to the main support 51. The guide frame one 52 has an L-shaped sliding groove one composed of a vertical groove one 521 and a horizontal groove one 522. The guide frame two 53 has an L-shaped sliding groove two composed of a vertical groove two 531 and a horizontal groove two 532. At the corner of the L-shaped sliding groove two, there is an obliquely upwardly arranged inclined groove 533.

[0036] Furthermore, a swing frame 54 is arranged between the guide frame one 52 and the guide frame two 53. On one side of the swing frame 54, a movable shaft one 55 is installed, and the movable shaft one 55 slides in the L-shaped sliding groove one. On the other side of the swing frame 54, at a position above the movable shaft one 55, a movable shaft two 56 is installed, and the movable shaft two 56 slides in the L-shaped sliding groove two. On one side of the main support 51, a linear driving component two 57 is arranged. The fixed end of the linear driving component two 57 is hinged to the main support 51, and the output end of the linear driving component two 57 is rotatably connected to the movable shaft one 55.

[0037] It should be noted that the linear driving component two 57 is a cylinder, as Figure 4 and Figure 5As shown, the first movable shaft 55 is located at the lowermost position of the first vertical groove 521. When the second linear drive component 57 pushes the first movable shaft 55 to move upward within the first vertical groove 521, the second movable shaft 56 moves upward within the second vertical groove 531. Then, the second movable shaft 56 enters the inside of the inclined groove 533 and remains stationary, while the first movable shaft 55 slides upward within the arc-shaped groove between the first vertical groove 521 and the first horizontal groove 522, causing the swing frame 54 to swing by 90 degrees. Next, the first movable shaft 55 slides inside the first horizontal groove 522, and the second movable shaft 56 also moves out of the inclined groove 533 and slides inside the second horizontal groove 532. That is to say, when the second linear drive component 57 pushes the first movable shaft 55 upward, the swing frame 54 first moves upward, then rotates 90 degrees, and finally moves horizontally.

[0038] Similarly, when the second linear drive component 57 drives the first movable shaft 55 to return, that is, the first movable shaft 55 first slides inside the first horizontal groove 522, and the second movable shaft 56 first slides inside the second horizontal groove 532; then the second movable shaft 56 enters the inclined groove 533, and the first movable shaft 55 slides downward within the arc-shaped groove between the first vertical groove 521 and the first horizontal groove 522; next, the first movable shaft 55 slides downward within the first vertical groove 521, and the second movable shaft 56 moves out of the inclined groove 533 and slides downward within the second vertical groove 531. That is to say, when the second linear drive component 57 drives the first movable shaft 55 downward, the swing frame 54 first moves horizontally, then rotates 90 degrees, and finally moves downward.

[0039] In this embodiment, as Figures 4 - 7 shown, the swing frame 54 is provided with a cross bar 541, and a sliding shaft 62 is fixedly connected to the lower heating pipe 61. The sliding shaft 62 is slidably installed on the cross bar 541. The lower heating pipe 61 has a lower oil inlet 66 and a lower oil outlet 67, and the lower oil inlet 66 and the lower oil outlet 67 are communicated with the oil supply component.

[0040] It should be noted that the oil supply component includes a storage tank 9 and a circulation pump 91. The input end of the circulation pump 91 is communicated with the storage tank 9, the output end of the circulation pump 91 is communicated with the lower oil inlet 66, the lower oil outlet 67 is communicated with the storage tank 9, and an electric heating device is arranged inside the storage tank 9 for heating the hydraulic oil inside the storage tank 9. The hydraulic oil circulates inside the lower heating pipe 61, so that the temperature of the lower heating pipe 61 rises, facilitating heating the folding position of the upward return 301.

[0041] In this embodiment, as Figure 8 shown, the heating component 32 further includes a rotating shaft 322. The upper end of the middle part of the rotating shaft 322 is hinged to the output end of the first linear drive component 31. The upper heating pipe 321 is connected to the rotating shaft 322 through a connecting shaft 323. The rotating shaft 322 is provided with an upper oil inlet 324 and an upper oil outlet 325 that are communicated with the upper heating pipe 321, and the upper oil inlet 324 and the upper oil outlet 325 are communicated with the oil supply component.

[0042] It should be noted that the linear driving component 1-31 is a cylinder, which is used to drive the upper heating pipe 321 to move. The upper oil inlet 324 is communicated with the output end of the circulating pump 91, and the upper oil inlet 324 is communicated with the storage tank 9.

[0043] In this embodiment, as Figure 3 shown, a backing plate 8 is fixedly installed at the lower side position of the support frame 2, and the backing plate 8 is used to press on the upper surface of the waterproof coiled material 300 located on the top of the brick formwork 200.

[0044] It should be noted that the backing plate 8 is used to press the waterproof coiled material 300 to prevent the waterproof coiled material 300 from detaching from the top of the brick formwork 200 during folding. The brick formwork 200 is a brick wall built around the cushion 100.

[0045] In this embodiment, as Figure 6 shown, the swing frame 54 is provided with a vertical rod 542. The folding assembly 7 includes a pressure roller 72. Fixed shafts 71 are fixedly connected to both sides of the vertical rod 542. The two ends of the pressure roller 72 are slidably connected to the fixed shafts 71. A second spring 73 is sleeved on the fixed shafts 71, and the two ends of the second spring 73 are respectively pressed against the pressure roller 72 and the vertical rod 542.

[0046] In this embodiment, the implementation method is specifically as follows: When performing the waterproof construction of the flat raft foundation, first, move this shear wall to the position where it needs to be folded and turned up 301. As Figure 1 shown, make the turned-up part 301 located above the lower heating assembly 6 and below the upper heating assembly 3. Then, the linear driving component 1-31 drives the upper heating pipe 321 to press on the folding position of the upper surface of the turned-up part 301 of the waterproof coiled material 300. Secondly, the linear driving component 2-57 pushes the movable shaft 1-55 upward to move the movable shaft 1-55 upward a small distance, that is, to make the lower heating pipe 61 press on the folding position of the lower surface of the turned-up part 301 of the waterproof coiled material 300. In this way, the upper heating pipe 321 and the lower heating pipe 61 are respectively located on the upper surface and the lower surface of the folding position (crease) and heat and soften it. After softening, the linear driving component 1-31 drives the upper heating pipe 321 to return, and the linear driving component 2-57 drives the movable shaft 1-55 upward again to make the swing frame 54 swing by 90 degrees. During this process, the lower heating assembly 6 is separated from the turned-up part 301. After the vertical rod 542 swings to the horizontal position, the folding assembly 7 contacts the lower surface of the turned-up part 301, and then the folding assembly 7 moves horizontally to one side of the vehicle body 1, so that the turned-up part 301 can be folded on the waterproof coiled material 300, and the pressure roller 72 presses on the surface of the turned-up part 301. When the folding position is softened, the linear driving component 2-57 pulls the movable shaft 1-55 back to make the lower heating assembly 6 and the folding assembly 7 return to the state as shown in Figure 2 and Figure 4Position. After such folding is completed and it softens and hardens, the crease position will no longer bulge.

[0047] After the first upward return 301 is folded, the next upward return 301 needs to be folded. When the waterproof coiled material 300 is laid, two adjacent pieces need to overlap each other, as Figure 9 shown. Therefore, when moving to the position of the next upward return 301, if the device is directly moved, one end of 61 will move to the overlapping position. At this time, if the upward return 301 is heated and softened, instead of heating the upward return 301 that should overlap above, a part of the upward return 301 below is heated. Therefore, the following technical solution is proposed.

[0048] Refer to the attached Figures 4 - 7 description. Specifically, belt pulleys 63 are rotatably connected to both sides of the cross bar 541. A belt 64 is driven on the two belt pulleys 63. The belt 64 is fixedly connected to the sliding shaft 62. A motor 65 is installed on the cross bar 541. The motor 65 is used to drive one of the belt pulleys 63 to rotate.

[0049] It should be noted that when it is necessary to move to the position of the next upward return 301, first move the vehicle body 1 forward a certain distance, but it should be noted that the lower heating pipe 61 is not moved to the overlapping position. Then drive the cross bar 541 to swing upward through the linear driving component two 57. The lower heating pipe 61 lifts the upward return 301 upward. For example, at this time, the end of the lower heating pipe 61 is located at point B on the upward return 301. Furthermore, drive the belt pulley 63 to rotate through the motor 65, so that the belt 64 drives the sliding shaft 62 and the lower heating pipe 61 to move, so that the lower heating pipe 61 completely moves to the lower part of the lifted upward return 301. In this way, the entire lower heating pipe 61 moves to the lower surface of the upward return 301. Then move the vehicle body 1 forward to the position, but at this time the lower heating pipe 61 also moves forward a certain distance. At this time, it is necessary to drive the lower heating pipe 61 to move back through the motor 65 again, so that the entire lower heating pipe 61 moves back to the lower surface of the upward return 301. Finally, drive the cross bar 541 back to the horizontal position through the linear driving component two 57 to continue the construction.

[0050] The above technical solution can avoid the lower heating pipe 61 extending to the lower surface of the next upward return 301 and prevent heating the next upward return 301 by first lifting the upward return 301 upward and then making the lower heating pipe 61 completely extend into the lower surface of the upward return 301.

[0051] When heating the next upward return 301 after the upward return 301 is folded, the linear driving component one 31 drives the upper heating pipe 321 to move to the folding position. Since the upward returns 301 overlap each other, the upper heating pipe 321 may move to the position of the previously folded upward return, for example, one end of the upper heating pipe 321 presses on as Figure 10The position of point A of the already folded upward return 301 shown fails to contact the next upward return 301 at the lapping position. Therefore, the above technical solution is proposed.

[0052] Referring to the attached drawings of the specification Figures 4 - 7 Specifically, a lead-out shaft 33 is movably inserted into the support frame 2. The end of the rotating shaft 322 is rotatably connected to the front end of the lead-out shaft 33. The rear end of the lead-out shaft 33 has a limit block 331. A first spring 34 is sleeved on the lead-out shaft 33. The two ends of the first spring 34 are respectively pressed against the support frame 2 and the front end of the lead-out shaft 33.

[0053] It should be noted that the linear drive component 31 drives the upper heating pipe 321 to move forward. Under the action of the first spring 34, the lead-out shaft 33 extends. When the limit block 331 contacts the rear end of the support frame 2, the lead-out shaft 33 stops moving, and the linear drive component 31 continues to push the upper end of the middle part of the rotating shaft 322, so that the upper heating pipe 321 swings downward, that is, swings from the front position of point A to the rear side, so as to press on the crease position of the upward return 301. In this way, the end of the upper heating pipe 321 is prevented from pressing on the already folded upward return 301.

[0054] Referring to the attached drawings of the specification Figure 12 This embodiment also provides a construction method for a special device for waterproof construction of a flat raft foundation, including the following steps: Step 1: Move the special device for waterproof construction of the flat raft foundation to the position where the upward return 301 needs to be folded, so that the upward return 301 is located above the lower heating assembly 6 and below the upper heating assembly 3; Step 2: The linear drive component 31 drives the upper heating pipe 321 to press on the folding position on the upper surface of the upward return 301 of the waterproof coiled material 300 to heat and soften the folding position; Step 3: The lower heating pipe 61 presses on the folding position on the lower surface of the upward return 301 of the waterproof coiled material 300 to heat and soften the folding position; Step 4: The folding assembly 7 folds the upward return 301 along the folding position.

[0055] Finally: The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
