Description

Technical Field

[0001] The utility model belongs to the technical field of building construction and relates to a limiting device for waterproof sills. Background Art

[0002] In building construction, waterproof sills are usually cast in place to effectively prevent water from flowing out and at the same time effectively prevent water from damaging other structures. The traditional waterproof sill construction method is to place the waterproof sill on the precast floor slab after casting, and fill the connecting surface of the two with mortar. Although it can meet the requirements of the one-piece molding of the precast floor slab and the waterproof sill, the strength is not enough and there is still a risk of water seepage; another construction method is to place the waterproof sill on the steel cage of the precast floor slab before pouring concrete, and cast it as a whole with the precast floor slab, but the waterproof sill is heavy and will bend the steel bars during the construction process, causing the formed waterproof sill to tilt and fail to meet the construction requirements. For this reason, a limit device for the waterproof sill is needed to solve the above technical problems. Utility Model Content

[0003] In order to solve the above-mentioned technical problems, the utility model provides a limiting device for a waterproof sill, which can accurately control the length of the waterproof sill embedded in the prefabricated floor slab and ensure that the waterproof sill after pouring meets the construction requirements.

[0008] Furthermore, one end of the third oblique rod is rotatably connected to the first oblique rod through a first ear plate, and the other end of the third oblique rod is rotatably connected to the second oblique rod through a second ear plate.

[0009] Furthermore, the support plate is rotatably connected to the first support column via a connecting block, and the end of the first support column away from the connecting block is rotatably connected to the second support column.

[0010] Furthermore, the connecting block is provided with a first groove, and the first supporting column is rotatably connected to the first groove via a limiting block.

[0011] Furthermore, the second support column is provided with a second groove, and is connected to the first support column via the second groove. A driving motor is provided in the second groove to provide power for the rotation of the first support column.

[0012] Furthermore, the support plate is rotatably connected to the reinforcement rod, and the end of the reinforcement rod away from the support plate is connected to the waterproof sill through a steel cable.

[0013] Furthermore, a caster is provided at the end of the second support column away from the first support column.

[0020] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] Reference Figure 1 As shown, a limiting device for waterproof sill can connect waterproof sill 1 and prefabricated floor slab 2, including support plate 3, embedded parts 4 embedded in prefabricated floor slab 2 and connected to waterproof sill 1, and adjustment components 5 connecting embedded parts 4 and support plate 3. Adjustment of adjustment components 5 can drive waterproof sill 1 to move, thereby changing the length of waterproof sill 1 embedded in prefabricated floor slab 2 after pouring. Before pouring concrete on prefabricated floor slab 2, waterproof sill 1 is hoisted above the template of prefabricated floor slab 2, and the height of waterproof sill 1 embedded in prefabricated floor slab 2 is changed by changing the length of adjustment components 5, and the adjustment process is stable and safe. It is equivalent to hoisting waterproof sill 1 onto prefabricated floor slab 2 and embedding it to a certain height of prefabricated floor slab 2 before pouring, so that waterproof sill 1 and prefabricated floor slab 2 after pouring are integrally formed, saving construction time and ensuring the shaping effect of waterproof sill 1.

[0022] Preferably, the adjustment assembly 5 includes a first oblique rod 51 and a second oblique rod 52 which are rotatably connected to each other, one end of both of which is slidably connected to the embedded part 4 , and the other end of both of which is slidably connected to the support plate 3 .

[0023] Preferably, the first diagonal rod 51 is slidably connected to the embedded part 4 through the first slider 53, and the other end is slidably connected to the support plate 3 through the second slider 54. The second diagonal rod 52 is slidably connected to the embedded part 4 through the third slider 55, and the other end is slidably connected to the support plate 3 through the fourth slider 56.

[0024] Preferably, the first slide groove 11, the second slide groove 12, the third slide groove 13 and the fourth slide groove 14 are located in the same plane, which is perpendicular to the horizontal plane. Regardless of the L-shaped part or the straight section of the waterproof sill, the plane where the first slide groove 11, the second slide groove 12, the third slide groove 13 and the fourth slide groove 14 are located is perpendicular to the horizontal plane, so that the hoisting adjustment process is up and down movement without deviation, avoiding affecting the construction effect.

[0025] Preferably, the side of the support plate 3 close to the waterproof sill 1 is provided with a second slide groove 12 for accommodating the second slider 54 and a fourth slide groove 14 for accommodating the fourth slider 56, and the side of the embedded part 4 close to the support plate 3 is provided with a first slide groove 11 for accommodating the first slider 53 and a third slide groove 13 for accommodating the third slider 55. In this embodiment, the outer side of the waterproof sill 1 is wrapped with the embedded part 4. Before pouring concrete, taking the embedded part 4 on the left side as an example, the top of the embedded part 4 is provided with a first slide groove 11, and the first slider 53 moves left and right along the first slide groove 11. The top of the first slider 53 is rotatably connected to the bottom of the first inclined rod 51. Correspondingly, the top of the embedded part 4 on the right side is provided with a third slide groove 13 for accommodating the third slider 55, and the top of the third slider 55 is rotatably connected to the second inclined rod 52. By sliding the first slider 53 in the first slide groove 11 and the third slider 55 in the third slide groove 13, the angle between the first inclined rod 51 and the second inclined rod 52 is changed, thereby achieving the change of the overall height and vertical height of the two. Of course, the left and right embedded parts 4 can be set as a whole, or can be set as two or more, which is not specifically limited here, as long as the same function is achieved. The contact area between the embedded parts 4 and the waterproof sill 1 is increased, so that the force is evenly distributed during the hoisting process, which is safer and more stable, ensuring the safety during the construction process, and also making the hoisting of the waterproof sill 1 more stable, further ensuring the shaping effect of the waterproof sill 1.

[0026] Preferably, one end of the third oblique rod 57 is rotatably connected to the first oblique rod 51 through the first ear plate 15, and the other end is rotatably connected to the second oblique rod 52 through the second ear plate 16. In this embodiment, a hydraulic cylinder is provided between the third oblique rod 57 and the second ear plate 16, and the output end of the hydraulic cylinder is connected to the third oblique rod 57, and the rotation angle between the first oblique rod 51 and the second oblique rod 52 is changed by pushing or pulling the third oblique rod 57.

[0027] Preferably, the support plate 3 is rotatably connected to the first support column 61 through the connection block 31, and the end of the first support column 61 away from the connection block 31 is rotatably connected to the second support column 62. When in use, multiple groups of first support columns 61 and second support columns 62 can be arranged at the bottom of the support plate 3 to stabilize the support plate 3, thereby providing stable support conditions for the hoisting process of the waterproof sill 1.

[0028] Preferably, the connecting block 31 is provided with a first groove 32 , and the first supporting column 61 is rotatably connected to the first groove 32 via a limiting block 63 .

[0029] Preferably, the diameter of the opening of the first groove 32 is smaller than the rotation diameter of the stopper 63. In this embodiment, a connection block 31 is provided at the bottom of the support plate 3, and a circular first groove 32 is provided at the bottom of the connection block 31. The stopper 63 can rotate in the first groove 32, thereby driving the first support column 61 to rotate. The diameter of the stopper 63 is larger than the first support column 61 and larger than the diameter of the opening of the first groove 32, so that the connection block 31 and the first support column 61 can only rotate relative to each other but cannot be separated from each other.

[0030] Preferably, the second support column 62 is provided with a second groove 64, which is connected to the first support column 61 through the second groove 64, and a driving motor is provided in the second groove 64 to provide power for the rotation of the first support column 61. In this embodiment, the top of the second support column 62 is provided with a second groove 64 with an opening facing the first support column 61, and the second groove 64 is provided with a thread matching the first support column 61, and the bottom of the first support column 61 is inserted into the second groove 64. Through the threaded connection between the two, the output end of the driving motor is connected to the bottom of the first support column 61, and the driving motor drives the first support column 61 to rotate, and the top of the first support column 61 performs a rotational motion in the first groove 32, and the up and down displacement of the first support column 61 drives the up and down displacement of the support plate 3. When in use, the motors on both sides can be driven at the same time. When it is necessary to reduce the length of the waterproof sill 1 embedded in the prefabricated floor 2, the driving motor drives the first support column 61 to move upward, and then drives the waterproof sill 1 to move upward against the support plate 3 to reduce the embedded length. When it is necessary to increase the embedded length, the same is true, which will not be further elaborated here.

[0031] Preferably, the support plate 3 is rotatably connected to the reinforcement rod 7, and the end of the reinforcement rod 7 away from the support plate 3 is connected to the waterproof sill 1 through the embedded part 4. In another embodiment, Figure 2 As shown, a reinforcing rod 7 is also provided between the support plate 3 and the embedded part 4. The bottom of the reinforcing rod 7 is fixed to the embedded part 4, and the top thereof is slidably connected to the support plate 3. After the embedded length is adjusted appropriately, the reinforcing rod 7 and the support plate 3 are fixed to each other by tightening the nut, which can not only limit the lateral movement of the support plate 3 (the reinforcing rod 7 here can only move up and down relative to the support plate 3), but also play a stable supporting role for the movement of the waterproof sill 1, effectively avoiding the displacement or tilt of the waterproof sill 1 during the construction process, better ensuring the pouring effect and making its appearance beautiful. Through the coordinated use of the first inclined rod 51, the second inclined rod 52, the reinforcing rod 7 and the embedded part 4, the hoisting of the waterproof sill 1 is made more stable and firm. At the same time, the reinforcing rod 7 is vertically arranged between the support plate 3 and the waterproof sill 1, which enhances the hoisting of the waterproof sill 1, avoids displacement during the concrete pouring process, and thus ensures the construction quality. It should be noted that the reinforcing rod 7 here can be one, two, or even more, and its setting position can be set as long as it does not interfere with the use of the adjustment component, and its number and size are not specifically limited.

[0032] Preferably, a caster 65 is provided at the end of the second support column 62 away from the first support column 61 .

[0033] Embodiment 1:

[0034] The waterproof barrier 1 in this embodiment includes two parts: an L-shaped structure and a straight structure.

[0035] The following is an example of the lifting of the straight structure. Figure 1 As shown, a plurality of connection blocks 31 are provided at the bottom of the support plate 3, and a stop block 63 is embedded in the first groove 32 at the bottom of the connection block 31. The stop block 63 is connected to the second support column 62 through the first support column 61. The bottom of the first support column 61 is threadedly connected to the second support column 62. The driving motor drives the first support column 61 to rotate, thereby driving the first support column 61 to lift up or pull down the support plate 3. When in use, the plurality of first support columns 61 and the second support columns 62 that cooperate with each other provide stable support for the support plate 3, and the height of the support plate 3 can be adjusted.

[0036] The driving caster 65 can drive the support plate 3 to move stably, and then drive the waterproof sill 1 to a preset position, and then adjust the length of the first support column 61 inserted into the second groove 64, and then drive the waterproof sill 1 to descend and insert it into the prefabricated floor. When in use, the caster 65 first hoists the waterproof sill 1 above the prefabricated floor 2, and then adjust the first support column 61 to increase the length of its insertion into the second groove 64, drive the waterproof sill 1 to descend to the vicinity of the specified position, and then adjust the third inclined rod 57, so that the adjustment is more precise, improving the construction quality.

[0037] The outer side of the linear structure waterproof sill is wrapped with an embedded part 4, and the top of the embedded part 4 is provided with a first slide groove 11 (left side) and a third slide groove 13 (right side). The first slide groove 11 is slidably connected with a first slider 53, and the third slide groove 13 is slidably connected with a third slider 55. The first slider 53 and the third slider 55 are both arranged on the central axis of the waterproof sill, and their sliding directions are along the length direction of the waterproof sill. The first slider 53 is rotatably connected with the first inclined rod 51, and the third slider 55 is rotatably connected with the second inclined rod 52. The top of the first inclined rod 51 is rotatably connected with the second slider 54, and the second slider 54 is slidably arranged in the second slide groove 12. The top of the second inclined rod 52 is rotatably connected with the fourth slider 56, and the fourth slider 56 is slidably arranged in the fourth slide groove 14. A third inclined rod 57 is arranged between the lower half of the second inclined rod 52 and the upper half of the first inclined rod 51. The third oblique rod 57 is rotatably connected to the second ear plate 16 via a hydraulic cylinder. The second ear plate 16 is disposed on the second oblique rod 52 . The third oblique rod 57 is rotatably connected to the first oblique rod via the first ear plate 15 .

[0038] When the third diagonal rod 57 is driven to lengthen, the first slider 53 and the third slider 55 approach each other, and the second slider 54 and the fourth slider 56 approach each other. At this time, the waterproof sill 1 moves downward, and the length thereof inserted into the prefabricated floor 2 increases.

[0039] When the third diagonal rod 57 is driven to shorten, the first slider 53 and the third slider 55 move away from each other, and the second slider 54 and the fourth slider 56 move away from each other. At this time, the waterproof sill 1 moves upward, and the length thereof inserted into the prefabricated floor 2 is reduced.

[0040] Therefore, by changing the length of the intersection of the first support column 61 and the second support column 62, the waterproof sill 1 is hoisted to the vicinity of the position point, and then by changing the length of the third diagonal rod 57, the upper and lower positions of the waterproof sill 1 are accurately adjusted, first roughly adjusting and then finely adjusting. The operation process is stable and safe, and the construction quality is improved.

[0041] Different from the straight structure, the embedded parts 4 in the L-shaped waterproof sill are respectively arranged on both sides of the structure, and the sliding direction of the first slide groove 11 and the third slide groove 13 is at a certain angle to the two sides of the L-shaped waterproof sill to ensure the stable lifting of the L-shaped structure. Of course, adaptive adjustment can also be made according to the different structures of the actual waterproof sill. The embedded parts 4 are only arranged on one side of the waterproof sill structure. At this time, its connection structure is consistent with the straight structure, which will not be further explained here.

[0042] Embodiment 2

[0043] Different from the first embodiment, in this embodiment, Figure 2 As shown, the support plate 3 is also provided with a through hole, and the position of the through hole can be staggered with the position of the slide slot. After the reinforcing rod 7 passes through the through hole, it is connected to the support plate 3 through a nut, and the bottom of the reinforcing rod 7 is threadedly connected to the embedded part 4. The reinforcing rod 7 is arranged at a place where the slide slot is far away from the inclined rod, which will not affect the use of the adjustment component 5, and at the same time ensure the stability of the waterproof sill during the hoisting process.

[0044] The beneficial effects of the utility model are that the first support column and the second support column are set as a rough adjustment structure, which can not only support and drive the support plate to move, but also form stable working conditions for the hoisting of the waterproof sill; through the mutual cooperation of the first inclined rod, the second inclined rod and the third inclined rod, the hoisting height adjustment is more accurate, and the rough adjustment is coordinated with the fine adjustment, which is more convenient for on-site construction personnel to make timely adjustments, and the operation is simple and efficient; the reinforcement rod is set to enhance the stability of the connection between the support plate and the embedded parts. At the same time, the inclined rod and the reinforcement rod form a stable support between the support plate and the waterproof sill, effectively avoiding the displacement or tilt of the waterproof sill during the construction process, and better ensuring the casting effect.

[0045] The above is a detailed description of the embodiments of the utility model, but the contents are only preferred embodiments of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
