Description

Technical Field

[0001] The utility model relates to the technical field of building construction equipment, in particular to an eccentric circle rotating hole blocking device. Background Art

[0002] During construction, there will be a need for pipes to pass through the floor slabs. Usually, when the floor slabs are poured, holes for pipes will be reserved. To facilitate the installation of pipes, the inner diameter of the reserved holes will be larger than the outer diameter of the pipes. After the pipes are installed, the gaps will be filled with concrete.

[0003] In existing technology, a formwork larger than the opening is typically cut to block the lower opening. A wire is fixed in the center, passed through the floor slab, and tied to a wooden stick placed above the upper opening. However, construction errors during floor slab pouring and pipe installation can cause the pipes to be misaligned with the reserved holes. Traditional formwork cannot be reused and must be recut each time, resulting in significant material loss. Furthermore, using wire for lifting can lead to loose formwork sealing, resulting in concrete leakage, misalignment, and inconsistent construction quality. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Example 1:

[0030] See also Figure 1-5 The present invention describes the above technical solution in detail through the following embodiments:

[0031] An eccentric circle rotating hole plugging device, comprising:

[0032] The fixed splint 1 includes two half rings 11, which are connected by an adjustment component. The half rings 11 are used to clamp the pipe 6. A mud support plate 2 is provided under the fixed splint 1, and an outer movable plate 3 is rotatably installed under the mud support plate 2.

[0033] The half ring 11 is divided into two by a stainless steel round tube, and the inner diameter of the half ring 11 is about 114mm. There is a gap between the half rings 11, the gap at the bottom is smaller, and the gap near the adjustment component is larger.

[0034] A fixing plate 12 and a clamping plate 13 are welded to the top of the outer sides of the two vertical sides of the half ring 11 respectively, and the fixing plates 12 and the clamping plates 13 on the two half rings 11 are opposite to each other.

[0035] A U-shaped groove is provided on the side of the clamping plate 13 away from the half ring 11 .

[0036] The adjustment assembly includes a T-shaped screw 14 , which is rotatably connected to the fixed plate 12 , and a head of the T-shaped screw 14 is slidably connected to the clamping plate 13 , and the head of the T-shaped screw 14 passes through the clamping plate 13 and is threadedly connected to a fixing nut 15 .

[0037] A washer 16 is mounted on the T-shaped screw 14 to improve the fixing effect. After the T-shaped screw 14 passes through the clamping plate 13, the fixing nut 15 is rotated to adjust the opening size of the half ring 11, making it easier to clamp the pipe 6.

[0038] The mud support plate 2 is not concentric with the fixed splint 1. The mud support plate 2 includes two support plates 21. The two support plates 21 are fixedly connected to the two half rings 11 respectively. A limiting structure is provided on the outer side of the support plate 21. A first limiting plate 25 is concentrically provided on the bottom surface of the support plate 21.

[0039] The supporting plate 21 is welded to the outer bottom of the semi-ring 11. The center of the supporting plate 21 differs by 15 mm from the center of the semi-ring 11. The supporting plate 21 is made by cutting steel plates, and the outer diameter of the supporting plate 21 is 190 mm.

[0040] The limiting mechanism includes two limiting rings 23 , which are fixedly connected to the two supporting plates 21 through limiting blocks 22 . Two guide grooves 24 are separated between each limiting ring 23 and the supporting plate 21 by the limiting blocks 22 .

[0041] The width of the guide groove 24 is 8 mm, the inner diameter of the limiting ring 23 is 206 mm, and the outer diameter of the limiting ring 23 is 220 mm.

[0042] There are two first limiting plates 25 , and the size and shape of each first limiting plate 25 are the same as those of the supporting plate 21 .

[0043] The first limiting plate 25 is fixed to the supporting plate 21 by welding.

[0044] The outer movable plate 3 and the mud support plate 2 are not concentric, the bottom surface of the first limiting plate 25 is flush with the bottom surface of the outer movable plate 3, and the outer movable plate 3 and the mud support plate 2 are located on the top surface below the floor slab 4 to block the through hole 5.

[0045] The center of the outer movable plate 3 and the mud support plate 2 differ by 15 mm.

[0046] The outer movable plate 3 includes two rotating plates 31 . The outer diameter of the rotating plate 31 is larger than the limiting ring 23 . Four limiting rods 33 are evenly welded on the top surface of the rotating plate 31 . The limiting rods 33 are inserted into the guide groove 24 and are slidably connected to the guide groove 24 .

[0047] The rotating plate 31 is made by cutting a steel plate. The inner diameter of the rotating plate 31 is 190 mm, and the outer diameter of the rotating plate 31 is 250 mm.

[0048] The limiting rod 33 can be a screw rod or a round steel bar, and the outer diameter of the limiting rod 33 is smaller than the width of the guide groove 24.

[0049] A rotation groove 32 is eccentrically provided on the inner side of the rotation plate 31 . The inner diameter of the rotation groove 32 is the same as that of the first limiting plate 25 . The first limiting plate 25 is rotatably mounted in the rotation groove 32 .

[0050] The first limiting plate 25 cooperates with the rotating plate 31 to block the through hole 5 .

[0051] When the operator of this embodiment uses the device, he removes the outer movable plate 3 and loosens the fixing nut 15 to separate the T-shaped screw 14 from the clamping plate 13, thereby separating the two half rings 11.

[0052] Keep the bottom surface of the mud support plate 2 facing upward, so that the two half rings 11 clamp the pipe 6, rotate the T-shaped screw 14, insert the T-shaped screw 14 into the clamping plate 13 and tighten the fixing nut 15 to achieve preliminary fixation.

[0053] Place the rotating plate 31 on the mud supporting plate 2 so that the limiting rod 33 is inserted downward into the guide groove 24 .

[0054] According to the eccentric angles of the pipe 6 and the through hole 5, the outer movable plate 3 and the mud supporting plate 2 are adjusted.

[0055] After the adjustment is completed, the fixing nut 15 is loosened to allow the half ring 11 to slide along the pipe 6 , but the T-shaped screw 14 will not separate from the clamping plate 13 .

[0056] Use a tool such as a wooden stick to push the device to slide along the pipe 6 until the rotating plate 31 and the first limiting plate 25 abut against the lower surface of the floor slab 4 and block the through hole 5.

[0057] Tighten the fixing nut 15 again and slide the device downward.

[0058] Then, concrete is injected from above the through hole 5. After the concrete solidifies, the device is removed for easy circulation and use.
