For those skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0026] Please refer to Figure 1 The embodiment of the utility model provides a modularized plugging device for concrete formwork, including inner support part, adjusting part and two joints 4, the plug 5 can be detachably arranged on the joint 4 for plugging the assembling hole set up on the concrete formwork.

[0027] It should be noted that the plug 5 can be selected to be conical or stepped and the hole is embedded with each other, and the surface of the plug 5 is provided with a waterproof layer, the waterproof layer is formed by brushing waterproof paint, to realize the waterproof function of the end part after plugging.

[0028] Please refer to Figures 1 to 2 In the embodiment, the outer part of the inner support part has at least three equidistant distribution of strutting devices 200, the strutting device 200 can expand outward relative to the inner support part, so that the inner support part can be fixed in the formwork assembling hole; The adjusting part is arranged at one end of the inner support part and is used for controlling the opening and closing of the strutting device 200; The adjusting part is used for controlling the strutting device 200 to open on the surface of the inner support part, so that the inner support part is fixed in the formwork assembling hole, so as to facilitate the modular assembly of different plugs 5 to plug different diameter assembling holes.

[0029] Specifically, the inner support part includes a reinforcing rod 11 and a reinforcing rod sleeve 12, the reinforcing rod 11 extends into the reinforcing rod sleeve 12 and is slidably connected with the reinforcing rod sleeve 12, so that the reinforcing rod 11 can be adjusted in extension and retraction in the reinforcing rod sleeve 12.

[0030] Please refer to Figures 2 to 3 The strutting device 200 includes a connecting rod, an arc plate 23 and a guide piece, wherein the connecting rod includes two support seats 21 and two groups of rotating rods 22, one group of rotating rods 22 includes two rotating rods 22, the end portions of the two support seats 21 and the two rotating rods 22 are rotatably connected to form a parallelogram, the two groups of rotating rods 22 are simultaneously distributed in parallel on both sides of the support seat 21, one support seat 21 is arranged on the surface of the reinforcing rod sleeve 12, so that the other support seat 21 can be adjusted in parallel with the reinforcing rod sleeve 12 and the distance therebetween.

[0031] In this way, the adjustable parallelogram structure of the opening device 200 has good adjustability. When adjusting the opening and closing of the opening device 200, the expansion or contraction of the opening device 200 can be realized by controlling the movement of the reinforcing rod sleeve 12. When the opening device 200 expands, the arc-shaped plate 23 on the outer side can tightly fit the inner wall of the formwork assembly hole, forming a stable support.

[0032] It is further explained that the arc-shaped plate 23 is connected with the support base 21 away from the reinforcing rod sleeve 12, and the surface thereof is arc-shaped and faces away from the side direction of the reinforcing rod sleeve 12.

[0033] In this way, the contact area between the opening device 200 and the inner wall of the formwork assembly hole is increased, and the tightness and reliability of the plugging are improved.

[0034] The adjusting part includes an end plate 31 and a screw rod 32. One end of the reinforcing rod 11 is provided with an internal screw hole 111. The end plate 31 is arranged on one end of the reinforcing rod 11. The screw rod 32 is connected with the end plate 31 and is screwed into the internal screw hole 111. By rotating the screw rod 32, the opening and closing degree of the opening device 200 can be accurately controlled.

[0035] In actual operation, the construction personnel only need to use a hexagonal wrench to insert into the hexagonal 321 at the end of the screw rod 32, and rotate the screw rod 32 clockwise or counterclockwise, so as to make the opening device 200 expand outward or contract inward, thereby realizing the adaptive plugging of different diameter assembly holes.

[0036] One end of the reinforcing rod 11 is provided with a mounting plate 14. The reinforcing rod sleeve 12 is provided with a guide hole 121 at one end facing the mounting plate 14. The mounting plate 14 is provided with a guide rod 13 matched with the guide hole 121.

[0037] The cooperation of the guide rod 13 and the guide hole 121 ensures the stability and linearity of the reinforcing rod 11 when sliding in the reinforcing rod sleeve 12, prevents the reinforcing rod 11 from deviating or shaking during the sliding process, and improves the reliability and service life of the whole device.

[0038] The guide is connected between the support base 21 and the mounting plate 14. The guide includes a sliding plate 24. One end of the sliding plate 24 is fixed with the support base 21, and the other end is slidably connected with the mounting plate 14. The surface of the mounting plate 14 is provided with a sliding groove, and the sliding plate 24 is slidably connected with the sliding groove.

[0039] In this way, the horizontal movement of one end of the part that can be expanded by the opening device 200 is limited, so that the opening device 200 can only move in the radial direction of the reinforcing rod 11.

[0040] Please refer to Figure 4The end plate 31 is provided with a rotating seat 311 at one end of the inner threaded hole 111, the screw rod 32 is rotationally connected with the rotating seat 311, and the end of the screw rod 32 is provided with an internal hex 321 accommodated in the end plate 31.

[0041] The rotating seat 311 enables the screw rod 32 to transmit power more stably when rotating, and ensures that the opening and closing action of the expansion device 200 is accurate, and meanwhile, the internal hex 321 is convenient for the construction personnel to operate with common tools, thereby improving the convenience and efficiency of construction.

[0042] In actual use, the inner support part of the device is inserted into the formwork assembly hole, the screw rod 32 is rotated by using the internal hex 321 with a tool, the screw rod 32 is threadedly connected with the reinforcing rod 11, the reinforcing rod sleeve 12 indirectly connected with the screw rod 32 slides relative to the reinforcing rod 11, and since one end of the arc-shaped plate 23 of the expansion device 200 is limited to slide on the mounting plate 14, the sliding of the reinforcing rod sleeve 12 enables the parallelogram structure composed of the two support seats 21 and the two groups of rotating rods 22 in the expansion device 200 to rotate, so that the distance between the arc-shaped plate 23 and the reinforcing rod sleeve 12 changes, that is, the arc-shaped plate 23 expands outward, until the arc-shaped plate 23 tightly fits the inner wall of the assembly hole, the fixing of the device is realized, the plug 5 with a proper size is selected according to the diameter of the formwork assembly hole and is installed on the joint 4, the plug 5 just blocks the opening of the assembly hole to prevent concrete leakage, after the concrete is poured, the plug 5 is rotated for quick disassembly, the screw rod 32 is rotated again to make the expansion device 200 contract, so that the device can be easily taken out of the formwork for next use, the whole process is simple to operate and does not need complicated tools, thereby greatly improving the construction efficiency and reducing the construction cost, and meanwhile, the forming quality of the concrete member is effectively ensured.

[0043] In this document, the front, back, up, down and other orientation words are defined according to the positions of the parts in the drawings and the positions of the parts relative to each other, just to express the technical scheme clearly and conveniently. It should be understood that they are relative concepts, which can be changed accordingly according to different ways of use and placement, and the use of the orientation words should not limit the scope of the utility model.

[0044] In the case of no conflict, the above-mentioned embodiments and features in the embodiments can be combined with each other.

[0045] The above-mentioned is only the preferred embodiment of the utility model, and does not limit the utility model, any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
