Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a high-low grade concrete demarcation device. Background Technique

[0002] In the process of modern building structure design, the concrete grade at the column and beam-column joint is higher than that of the beam body. Therefore, in the actual construction process, if the high-grade concrete used at the beam-column joint flows into the area where the low-grade concrete is used for the beam body, it will not only increase the consumption of high-grade concrete, but also affect the overall structural strength of the beam body concrete. After retrieval, the patent with the Chinese patent publication number CN218970664U discloses a high-low grade concrete pouring and separating device for beam-column joints of small-section beams, which includes an installation frame, one side of the installation frame is open, and a number of adjusting plates are installed in the installation frame. A first gap is arranged between two adjacent adjusting plates, and the side formwork of the beam body to be poured is inserted into the first gap. This application has the effect of reducing the high-grade concrete flowing into the area where the beam body is located.

[0003] Although the above technical solution can reduce the high-grade concrete flowing into the area where the beam body is located, due to the existence of steel bars during use, there are corresponding gaps during use. Although the airbag can be used for blocking, the airbag is easily deformed, resulting in partial leakage. At this time, the high-low grade concrete will be mixed, affecting the damping quality, and during use, each airbag needs to be inflated and deflated separately, with cumbersome operations, thus reducing the work efficiency.

[0024] Embodiment 1:

[0025] AsFigure 1 and Figure 2 As shown in Figure 2 , a device for demarcating high and low grade concrete includes a steel bar frame 1 and a formwork frame 2. The steel bar frame 1 is located inside the formwork frame 2. A demarcation mechanism 3 is inserted at the top of the steel bar frame 1. The demarcation mechanism 3 includes a cross bar 31. Two first partition plates 32 are symmetrically and fixedly connected to both sides of the lower surface of the cross bar 31. A plurality of second partition plates 33 are fixedly connected in sequence between the two first partition plates 32 on the lower surface of the cross bar 31. The steel bar frame 1 includes a plurality of main steel bars 11 arranged in a rectangular array. A plurality of stirrups 12 are fixedly sleeved in sequence between the outer surfaces of the plurality of main steel bars 11. The first partition plate 32 is located between the formwork frame 2 and the steel bar frame 1. The second partition plate 33 is located between two adjacent main steel bars 11.

[0026] During use, insert the second partition plate 33 between two adjacent main steel bars 11 correspondingly, and make the two first partition plates 32 respectively located between the inner sides of the two sides of the formwork frame 2 and the outer sides of the two sides of the steel bar frame 1. Then fix the cross bar 31 on the formwork frame 2 through threaded fasteners or the like. At this time, the first partition plate 32 and the second partition plate 33 can initially separate the steel bar frame 1.

[0027] Embodiment 2:

[0028] As Figure 2 and Figure 6 shown in Figure 6 , an adjustment and sealing mechanism 4 is installed inside the demarcation mechanism 3. The adjustment and sealing mechanism 4 includes a first receiving groove 41 opened on one side of the outer surface of the first partition plate 32. A first adjustment plate 42 is slidably connected inside the first receiving groove 41. Two first lead screws 43 threadedly connected to the first adjustment plate 42 are symmetrically and rotatably connected through the first receiving groove 41. Second receiving grooves 44 are opened on both sides of the outer surface of the second partition plate 33. A second adjustment plate 45 is slidably connected inside the second receiving grooves 44. Two second lead screws 46 threadedly connected to the second adjustment plate 45 are symmetrically and rotatably connected through the second receiving grooves 44. Semi-circular grooves 47 matching the main steel bars 11 are opened on the outer surfaces of the first adjustment plate 42 and the second adjustment plate 45. Long holes 48 are opened in the middle of the first partition plate 32 and the second partition plate 33. One end of each of the first lead screw 43 and the second lead screw 46 extends into the long hole 48 and is fixedly connected with a first bevel gear 49. A rotating shaft 410 is rotatably connected through the long hole 48. A second bevel gear 411 meshing with the first bevel gear 49 is fixedly connected to the outer surface of the rotating shaft 410.

[0029] The rotation of the rotating shaft 410 drives the rotation of the second bevel gear 411. Through the first bevel gear 49, the corresponding first lead screw 43 and second lead screw 46 can be driven to rotate, thereby driving the corresponding first adjusting plate 42 and second adjusting plate 45 to move. Then, under the action of the semi-circular groove 47, the gap between the main steel bars 11 can be blocked, achieving complete closure and avoiding the mixing of high and low-strength concretes during pouring, improving the pouring effect, and thus solving the problem that the device cannot be completely closed and partial mixing of high and low-strength concretes will affect the building quality.

[0030] Embodiment 3:

[0031] As Figures 2 to 7 shown, a driving mechanism 5 is installed inside the demarcation mechanism 3 and is matched with the adjustment and sealing mechanism 4. The driving mechanism 5 includes a long groove 51 opened at the top of the cross bar 31. The top end of the rotating shaft 410 extends into the long groove 51 and is fixedly connected with a third bevel gear 52. A driving shaft 53 is rotatably connected through the long groove 51. The outer surface of the driving shaft 53 is fixedly connected with a fourth bevel gear 54 meshing with the third bevel gear 52. Both ends of the driving shaft 53 are fixedly connected with turntables 55.

[0032] Rotating any turntable 55 can drive the driving shaft 53 to rotate. The rotation of the driving shaft 53 drives the fourth bevel gear 54 to rotate, and then multiple rotating shafts 410 can be driven to rotate simultaneously through multiple third bevel gears 52. The operation is simple and the work efficiency is improved, thus solving the problem that the existing device needs to be operated separately, resulting in a reduction in work efficiency.

[0033] Working principle: During use, insert the second partition 33 between two adjacent main steel bars 11, and make the two first partitions 32 located between the inner sides of the formwork frame 2 and the outer sides of the steel bar frame 1 respectively. Then, fix the cross bar 31 on the formwork frame 2 through threaded fasteners. At this time, the first partition 32 and the second partition 33 can initially separate the steel bar frame 1.

[0034] Rotating any turntable 55 can drive the driving shaft 53 to rotate. The rotation of the driving shaft 53 drives the fourth bevel gear 54 to rotate, and then multiple rotating shafts 410 can be driven to rotate simultaneously through multiple third bevel gears 52. The operation is simple and the work efficiency is improved, thus solving the problem that the existing device needs to be operated separately, resulting in a reduction in work efficiency.

[0035] The rotation of the rotating shaft 410 drives the rotation of the second bevel gear 411. Through the first bevel gear 49, the corresponding first lead screw 43 and the second lead screw 46 can be driven to rotate, so that the corresponding first adjusting plate 42 and the second adjusting plate 45 can be driven to move. Then, under the action of the semi-circular groove 47, the gap between the main steel bars 11 can be blocked, and complete closure can be achieved, avoiding the mixing of high and low strength concretes during pouring, improving the pouring effect, and thus solving the problem that the device cannot be completely closed and part of the high and low strength concretes will be mixed, which affects the construction quality.
