Description

Technical Field

[0001] The utility model relates to the technical field of blocking reserved holes in external walls, in particular to a blocking device for reserved holes of cantilevered I-beams. Background Art

[0002] In construction projects, cantilevered I-beams are required as supports for the construction of unloading platforms and external scaffolding supports of high-rise buildings to ensure the orderly progress of the construction process. After the main construction is completed, the cantilevered I-beams need to be removed in time, and the holes reserved for the cantilevered I-beams on the wall need to be sealed with concrete. When sealing the holes reserved for cantilevered I-beams on the wall, the traditional sealing method is to support formwork on both sides of the reserved holes, then pour concrete, and remove the formwork after the concrete solidifies; but in the specific construction process, since the formwork needs to be supported on the outside of the main body and suspended grouting is required, the formwork support and grouting process are more difficult during the construction process, and it is easy to cause water seepage on the external wall due to unstable formwork support during pouring.

[0003] In order to overcome the above problems, a Chinese patent with patent number CN209891691U discloses a water-seepage-resistant external wall cantilever frame I-beam reserved hole plugging device, which utilizes the steel wire for pulling and fixing the template and the PVC sleeve to achieve the installation of the outer template and the inner template at the reserved hole, thereby ensuring the waterproof effect of plugging the reserved hole. However, when the above-mentioned plugging device is in use: when removing the inner and outer templates on the reserved hole, the device needs to first release the fixation of the inner and outer templates, then take the steel wire for pulling and fixing the template, and then plug the PVC sleeve, which makes the construction process cumbersome and inconvenient to quickly plug the reserved hole.

[0004] Therefore, the utility model proposes a cantilever frame I-beam reserved hole blocking device to solve the problems existing in the above-mentioned prior art. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] When implementing: Figure 1-4 As shown, the utility model provides a solution: a cantilever frame I-beam reserved hole blocking device, comprising:

[0026] An exterior wall 1, wherein a reserved hole 2 is opened on the surface of the exterior wall 1, and an outer template 3 and an inner template 4 are respectively installed on both sides of the exterior wall 1, and a blocking mechanism 5 for blocking the reserved hole 2 is arranged between the surfaces of the outer template 3 and the inner template 4;

[0027] The blocking mechanism 5 includes a reinforcing rib frame 51 arranged on the inner wall of the reserved hole 2, and a plurality of mounting rods 52 are fixedly connected to the inner side of the reinforcing rib frame 51, and a plurality of connecting rods 53 are fixedly connected to one side of the outer template 3 and the inner template 4, and the surface of the connecting rod 53 is clamped on the inner wall of the mounting rod 52, and the inner wall of the connecting rod 53 is slidably connected with a mounting block 54, and a connecting frame 55 is fixedly connected to one side of the mounting block 54, and the surface of the mounting block 54 is clamped on the inner wall of the mounting rod 52, and a blocking component 56 is arranged between the surfaces of the outer template 3 and the inner template 4.

[0028] When it is necessary to seal the reserved hole, the reserved hole is chiseled and flushed, and the reinforcing rib frame 51 is placed into the reserved hole 2. The inner template 4 and the outer template 3 are respectively in contact with the reserved hole 2, so that the connecting rod 53 is clamped on the mounting rod 52, and the connecting frame 55 is driven to move up, so that multiple mounting blocks 54 are simultaneously clamped into the mounting rod 52, so that the inner template 4 and the outer template 3 respectively seal the reserved hole 2, at this time, concrete is poured into the inclined surface on the inner template 4, so that the concrete flows into the reserved hole 2, and then the poured concrete is vibrated and compacted. After the concrete in the reserved hole 2 solidifies, the connecting frame 55 is driven to move down, and the connecting frame 55 moves down to drive multiple mounting blocks 54 to retract into the connecting rod 53, release the fixation of the inner template 4 and the outer template 3, and pull the inner template 4 and the outer template 3 away from the blocked reserved hole 2. At this time, the blocked reserved hole 2 is painted with waterproof material to ensure that the blocking of the reserved hole 2 is simple.

[0029] As a preferred embodiment, Figure 3As shown, the blocking assembly 56 includes a protective rod 562 fixedly connected to the top of the connecting frame 55, the front ends of the outer template 3 and the inner template 4 are rotatably connected to a screw rod 561, the surface of the screw rod 561 is threadedly connected to the inner wall of the protective rod 562, and one side of the outer template 3 and the inner template 4 is fixedly connected to a cover block 564.

[0030] The screw rod 561 rotates to drive the protection rod 562 and the connecting frame 55 to move upward, thereby fixing the outer template 3 and the inner template 4 on the reserved hole 2.

[0031] The cover block 564 ensures that when the inner template 4 and the outer template 3 are removed, due to the tight fit between the multiple round blocks and the reserved holes 2, the inner template 4 and the outer template 3 are easier to be pulled out as a whole, rather than being locally stuck or damaged, thereby ensuring that the removal of the inner template 4 and the outer template 3 is more convenient.

[0032] As a preferred embodiment, Figure 3 and Figure 5 As shown, the front ends of the outer formwork 3 and the inner formwork 4 are fixedly connected with a protective tube 566, the surface of the protective rod 562 is slidably connected to the inner wall of the protective tube 566, the inner wall of the screw rod 561 is slidably connected with a reinforcing rod 568, and the surface of the reinforcing rod 568 is clamped to the inner wall of the protective tube 566. The protective tube 566 and the protective rod 562 are used to prevent concrete from adhering to the screw rod 561, thereby reducing the wear of the screw rod 561.

[0033] The reinforcing rod 568 is used to lock the screw rod 561, ensuring that the inner formwork 4 and the outer formwork 3 are fixed to the outer wall 1 more stably.

[0034] As a preferred embodiment, Figure 3 As shown, the inner walls of the outer template 3 and the inner template 4 are both provided with a movable groove 563, the surface of the connecting frame 55 is slidably connected to the inner wall of the movable groove 563, and the surface of the connecting frame 55 is fixedly connected with a shielding block 567. The shielding block 567 is used to cover and block the movable groove 563, thereby preventing impurities from entering the movable groove 563.

[0035] As a preferred embodiment, Figure 3 As shown, the surface of the protection rod 562 is fixedly connected with an anti-deflection block 565, and the surface of the anti-deflection block 565 is slidably connected to the inner wall of the protection tube 566. The movement of the protection rod 562 drives the anti-deflection block 565 to move in the protection tube 566, ensuring that the protection rod 562 can remain stable during movement.

[0036] When the cantilever frame I-beam reserved hole blocking device of the utility model is used: the reserved hole is chiseled and flushed, the reinforcing rib frame 51 is placed in the reserved hole 2, the inner template 4 and the outer template 3 are respectively against the reserved hole 2, so that the connecting rod 53 is clamped on the installation rod 52, and the screw rod 561 is rotated. The screw rod 561 rotates through the connecting frame 55 to drive multiple installation blocks 54 to be clamped in the installation rod 52 at the same time, so that the inner template 4 and the outer template 3 respectively block the reserved hole 2. At this time, the inclined plate on the inner template 4 is tilted. Concrete is poured into the inclined surface to make the concrete flow into the reserved hole 2, and then the poured concrete is vibrated to make it dense. After the concrete in the reserved hole 2 solidifies, the screw rod 561 is rotated, and the screw rod 561 rotates through the connecting frame 55 to drive multiple mounting blocks 54 to retract into the connecting rod 53, thereby releasing the fixation of the inner template 4 and the outer template 3, and pulling the inner template 4 and the outer template 3 away from the blocked reserved hole 2. At this time, the blocked reserved hole 2 is coated with waterproof material to ensure that the blocking operation of the reserved hole 2 is simple.

[0037] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
