Description

Technical Field

[0001] The invention relates to the technical field of scaffolding and formwork, and in particular to an inflatable anti-leakage plugging device for a beam and slab post-casting strip. Background Art

[0002] The beam-slab is a combination of interacting beams and slabs in the floor slab. The post-cast strip is a concrete strip left at the corresponding position of the foundation slab, wall, and beam in accordance with the design or construction specifications to prevent harmful cracks that may be caused by uneven shrinkage or settlement of reinforced concrete structures during construction. The inflatable anti-leakage plugging device can withstand water pressure after the concrete is poured to prevent leakage of the post-cast strip, ensuring that water in the building's basement, pool, pipes, etc. is not leaked, effectively avoiding later maintenance and treatment. Technical inspiration for the inflatable anti-leakage plugging device; Research on inflatable leak-proof plugging devices found the following problems: The inflatable anti-leakage plugging device usually inflates the airbag to form support inside the gap of the post-casting strip. Since the post-casting strip of the beam and slab is usually made of concrete, when the concrete solidifies, there are bulges inside the concrete gap, and the surface of the airbag is easily damaged and leaked due to the bulges. As a result, the inflatable anti-leakage plugging device cannot prevent the airbag from shrinking rapidly as a whole after the airbag leaks rapidly due to surface damage. At present, CN202210301331.3 in the prior art discloses a post-casting strip formwork structure for preventing slurry leakage, which discloses a formwork structure. The invention comprises two mounting parts located on the supporting floor slab, the mounting part comprises two connecting units and an L-shaped plate connecting the two connecting units together, the connecting unit comprises a bottom plate and a mounting plate located at the upper end of the bottom plate, at least one mounting assembly is arranged between the bottom plate and the mounting plate, the mounting assembly connects the floor and the mounting plate together, the mounting plate of the connecting unit is fixedly connected to the bottom plate of the adjacent connecting unit, the L-shaped plate is just clamped on the mounting plate at the lower end and the bottom plate at the upper end at the same time, a movable groove is provided on the upper end surface of the bottom plate, a first steel bar groove is provided on the bottom of the movable groove, a second steel bar groove is provided on the lower end surface of the mounting plate, and a reinforcing beam is also arranged between the two adjacent L-shaped plates, which can prevent slurry leakage from the formwork; The present invention can mainly solve the problem that the inflatable anti-leakage blocking device cannot prevent the overall shrinkage of the airbag after the airbag leaks rapidly due to surface damage. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides an inflatable anti-leakage plugging device for the post-cast strip of beams and slabs to solve the problems described in the above background technology.

[0004] The purpose and efficacy of the inflatable anti-leakage plugging device for the post-cast strip of a beam and slab of the present invention are achieved by the following specific technical means: an inflatable anti-leakage plugging device for the post-cast strip of a beam and slab, comprising a sealing airbag, the end of which is connected to an air pump, the outer side of the sealing airbag is surrounded by a side airbag, and the outer side of the side airbag is surrounded by an outer ring.

[0005] Furthermore, a pressure gauge and a three-way connection are passed through one end of the blocking airbag close to the air pump, and the air pump is an electric air pump.

[0006] Furthermore, the side airbag is in a semicircular shape, the outer ring is connected to the inside of the side airbag, the outer ring is in a circular shape, and the side airbag surrounds the outside of a plurality of blocking airbags.

[0007] Furthermore, the clamping ring and the shrinking ring are respectively matched and surrounded at the two ends of the outer side of the blocking airbag, and the clamping ring and the shrinking ring are both arranged in an arc shape with an arc angle of 90-120 degrees, and the interior of the clamping ring is hollow.

[0008] Furthermore, a cross bar penetrates one end of the side airbag near the blocking airbag, a sleeve is provided at one end of the cross bar, and an extension rod and a top ring are slidably nested and connected in sequence at one end of the sleeve away from the cross bar.

[0009] Furthermore, the cross bar and the sleeve are integrally combined into a "T" shape, the interior of the sleeve is hollow, and the extension rod is matched with the sleeve.

[0010] Furthermore, the top ring is in a semicircular shape, connected to one end of the extension rod, and the top ring slides on one end of the sleeve through the extension rod.

[0011] Furthermore, convex rings are inlaid on both sides of the inner wall of the clamping ring, a track is passed through the inside of the convex ring, a sliding frame is slidably connected to the inner side of the track, a rotating sphere is hinged at one end of the sliding frame away from the clamping ring, and one end of the rotating sphere is swingably connected to a side plate.

[0012] Furthermore, the protrusions are in a semicircular shape, and 6-8 groups of protrusions are distributed inside the clamping ring. The protrusions are made of the same material as the sealing airbag.

[0013] Furthermore, the track is inclined at 5-35 degrees, the track on both sides of the clamp ring are inclined in opposite directions, the track is matched with a sliding frame, and the sliding frame extends to one end of the track close to the shrink ring.

[0014] Furthermore, the side panel is centered on the rotating sphere, the weight of the upper end of the side panel is 5-10g greater than the weight of the lower end, and the side panel swings in a vertical direction through the rotating sphere.

[0015] Beneficial effects: 1. After the blocking airbag expands due to the entry of air, the side airbag expands synchronously. The air enters the side airbag through the blocking airbag, and the air can impact one end of the top ring. The top ring slides on one end of the sleeve through the extension rod. The extension rod slides and extends on the inner side of the sleeve, and the top ring slides toward one end of the top wall of the side airbag. At this time, the top ring can support one end of the inner wall of the side airbag, so that the side airbag can use the impact generated by the entry of air to increase the support inside the side airbag through the top ring; 2. After the air inside the blocking airbag and the side airbag is exhausted, the air cannot impact one end of the top ring, so the side airbag and the blocking airbag are in a contracted state, and the extension rod is in a movable state at one end of the sleeve, and the top ring is synchronously in a movable state inside the side airbag through the extension rod, so that the side airbag is contracted as a whole outside the blocking airbag; 3. When the blocking airbag expands and contracts as a whole, the blocking airbag is in a state of slow expansion and contraction as a whole, so the clamp ring and the shrink ring are in a state of slow sliding nesting or sliding contraction. When the shrink ring slowly slides to the inside of the clamp ring, one end of the shrink ring is squeezed to one side of the convex ring, and the side plate inside the convex ring slides on the inner side of the track through the sliding frame. When the side plate and the sliding frame slide to one end of the track, the side plate and the sliding frame are in a stagnant state, and the shrink ring continues to slide toward the inside of the clamp ring, which facilitates the overall contraction of the blocking airbag; 4. When the shrink ring slides toward the outside of the clamp ring, the shrink ring is extruded to one side of the side plate through reverse extrusion, and the side plate slides synchronously through the sliding frame. When the sliding frame and the side plate slide to one side of the track, the shrink ring continues to slide toward the outside of the clamp ring, and the clamp ring and the shrink ring can form a surrounding support for the outside of the blocking airbag; 5. When the concrete inside the post-cast strip solidifies and the surface of the sealing airbag is damaged by the concrete, the sealing airbag is in a rapid contraction state, and the shrinking ring quickly retracts to the inside of the clamping ring. The shrinking ring can be quickly squeezed to one side of the convex ring. The convex ring is deformed due to the rapid squeezing of the shrinking ring, so the shrinking ring can be squeezed to one end of the side plate. At this time, due to the rapid impact of the shrinking ring, the side plate is vertically tilted and swung through the rotating sphere. Therefore, the side plates on both sides of the clamping ring can form a limit clamp on one end of the shrinking ring to prevent the shrinking ring from further shrinking toward the inside of the clamping ring. By fixing the shrinking ring, the shrinking ring and the clamping ring as a whole can support the outside of the sealing airbag to prevent the sealing airbag from being unable to support the inside of the post-cast strip due to air leakage due to surface damage of the sealing airbag.

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Example

[0026] As attached Figure 1 To Attachment Figure 8 As shown: Embodiment 1: An inflatable anti-leakage plugging device for a beam and slab post-casting strip, comprising a plugging airbag 1, an end of which is connected to an air pump 101, a side airbag 2 surrounding the outside of the plugging airbag 1, and an outer ring 201 surrounding the outside of the side airbag 2; Among them: a blocking airbag 1, a pressure gauge and a three-way connection are connected to one end of the blocking airbag 1 close to the air pump 101, and the air pump 101 is an electric air pump; The air pump 101 is connected to the power supply circuit via a power line; The side airbag 2 is in a semicircular ring shape, the outer ring 201 is connected with the inside of the side airbag 2, the outer ring 2 is in a circular ring shape, and the side airbag 2 surrounds the outside of the blocking airbag 1; By placing the side airbag 2 on the outside of the plugging airbag 1, it is possible to avoid the situation where the plugging airbag 1 is unable to plug smaller cracks inside the beam and slab post-casting strip due to the large overall volume of the plugging airbag 1. A clamp ring 4 surrounds the outer side of the end of the blocking airbag 1 away from the inflator 101, and shrink rings 401 are slidably nested and connected at both ends of the clamp ring 4, and the shrink ring 401 surrounds the outer side of the blocking airbag 1; The clamp ring 4 and the shrink ring 401 are respectively matched and surround the two ends of the outer side of the blocking airbag 1. The clamp ring 4 and the shrink ring 401 are both arranged in an arc shape with an arc angle of 90-120 degrees. The interior of the clamp ring 4 is hollow. The clamp ring 4 and the shrink ring 401 are respectively matched and surrounded at the two ends of the outer side of the blocking airbag 1, and the clamp ring 4 and the shrink ring 401 can form support for the two ends of the outer side of the blocking airbag 1; Wherein: the air pump 101 is an electric air pump, when the plugging airbag 1 is not inflated, the shrink ring 401 shrinks to the inner side of the clamp ring 4, the plugging airbag 1 is manually placed inside the beam and slab post-casting strip, the air pump 101 inflates the inside of the plugging airbag 1, the plugging airbag 1 gradually inflates, the side airbag 2 and the outer ring 201 inflate synchronously, and the side airbag 2 surrounds the outside of the plugging airbag 1, so that the outside of the plugging airbag 1 can form a tight seal according to the cracks in the beam and slab post-casting strip, so as to avoid the plugging airbag 1 being too large in overall volume, resulting in the plugging airbag 1 being unable to form a seal on the smaller cracks inside the beam and slab post-casting strip; Example 2: Refer to the attached manual Figure 2-4 It can be seen that the difference between Example 2 and Example 1 is that a cross bar 3 is passed through the end of the side airbag 2 close to the blocking airbag 1, a sleeve 301 is provided at one end of the cross bar 3, and an extension rod 302 and a top ring 303 are slidably nested and connected in sequence at the end of the sleeve 301 away from the cross bar 3; Among them: the cross bar 3, the cross bar 3 and the sleeve 301 are combined into a "T" shape, the sleeve 301 is hollow inside, and the extension rod 302 is matched with the sleeve 301; A top ring 303, which is in a semicircular shape and connected to one end of the extension rod 302, and slides on one end of the sleeve 301 through the extension rod 302; Wherein: after the blocking airbag 1 is expanded due to the entry of air, the side airbag 2 is expanded synchronously, and the air enters the side airbag 2 through the blocking airbag 1, and the air can impact one end of the top ring 303, and the top ring 303 slides on one end of the sleeve 301 through the extension rod 302, and the extension rod 302 slides and extends on the inner side of the sleeve 301, and the top ring 303 slides toward one end of the top wall of the side airbag 2. At this time, the top ring 303 can form a support for one end of the inner wall of the side airbag 2, so that the side airbag 2 can use the impact generated by the entry of air to increase the support inside the side airbag 2 through the top ring 303; After the air inside the blocking airbag 1 and the side airbag 2 is exhausted, the air cannot impact one end of the top ring 303, so the side airbag 2 and the blocking airbag 1 are in a contracted state, and the extension rod 302 is in a movable state at one end of the sleeve 301, and the top ring 303 is in a movable state inside the side airbag 2 through the extension rod 302, so that the side airbag 2 is contracted as a whole outside the blocking airbag 1; Example 3: Refer to the attached manual Figure 2 , 5 -8, it can be known that the difference between Example 3 and Example 1-2 is that convex rings 402 are inlaid on both sides of the inner wall of the snap ring 4, a track 403 runs through the inside of the convex ring 402, a sliding frame 404 is slidably connected to the inner side of the track 403, a rotating ball 405 is hinged at one end of the sliding frame 404 away from the snap ring 4, and a side plate 406 is swingably connected to one end of the rotating ball 405; Wherein: the protrusion 402 is in a semicircular ring shape, and 6-8 groups of protrusions 402 are distributed inside the clamp ring 4, and the protrusion 402 is made of the same material as the blocking airbag 1; When the shrink ring 401 slides toward the inside of the clamp ring 4, both sides of the end of the shrink ring 401 can be squeezed to one side of the protrusion 402; The track 403 is inclined at 5-35 degrees, and the tracks 403 on both sides of the clamp ring 4 are inclined in opposite directions. The track 403 is matched with a sliding frame 404, and the sliding frame 404 extends to one end of the track 403 close to the shrink ring 401; The track 403 is inclined at 5-35 degrees, so when one end of the convex ring 402 is not squeezed, the sliding frame 404 is located at the end of the track 403 close to the shrink ring 401; The tracks 403 on both sides of the clamp ring 4 are inclined in opposite directions, so that when the shrink rings 401 at both ends of the clamp ring 4 slide and shrink toward the inner side of the clamp ring 4 at the same time, the shrink rings 401 can be squeezed to the sliding frame 404 at the downwardly inclined end of the track 403 simultaneously; The side plate 406 is centered on the rotating sphere 405, the weight of the upper end of the side plate 406 is 5-10g greater than the weight of the lower end, and the side plate 406 swings in a vertical direction through the rotating sphere 405; The side plate 406 is centered on the rotating sphere 405. The weight of the upper end of the side plate 406 is 5-10g greater than the weight of the lower end. Therefore, when one side of the convex ring 402 is not squeezed, the side plate 406 is tilted 25-45° as a whole, and one side of the upper end of the side plate 406 is in close contact with the inner wall of the convex ring 402. Please refer to the attached manual for details. Figure 8 As shown; Wherein: when the blocking airbag 1 is expanded and contracted as a whole, the blocking airbag 1 is in a slow expansion and contraction state as a whole, so the clamp ring 4 and the shrink ring 401 are in a slow sliding nesting or sliding shrinking state, and when the shrink ring 401 slowly slides to the inside of the clamp ring 4, one end of the shrink ring 401 is squeezed to one side of the convex ring 402, and the inner side plate 406 of the convex ring 402 slides on the inner side of the track 403 through the sliding frame 404, and when the side plate 406 and the sliding frame 404 slide to one end of the track 403, the side plate 406 and the sliding frame 404 are in a stagnant state, and the shrink ring 401 continues to slide toward the inside of the clamp ring 4, so as to facilitate the overall contraction of the blocking airbag 1; When the shrink ring 401 slides toward the outside of the clamp ring 4, the shrink ring 401 is reversely extruded to one side of the side plate 406, and the side plate 406 slides synchronously through the sliding frame 404. After the sliding frame 404 and the side plate 406 slide to one side of the track 403, the shrink ring 401 continues to slide toward the outside of the clamp ring 4, and the clamp ring 4 and the shrink ring 401 can form a surrounding support for the outside of the blocking airbag 1; When the concrete inside the post-cast strip solidifies and the surface of the sealing airbag 1 is damaged by the concrete, the sealing airbag 1 is in a rapid contraction state, and the shrinking ring 401 quickly retracts to the inside of the clamping ring 4, and the shrinking ring 401 can be quickly squeezed to one side of the convex ring 402. The convex ring 402 is deformed due to the rapid squeezing of the shrinking ring 401, so the shrinking ring 401 can be squeezed to one end of the side plate 406. At this time, due to the rapid impact of the shrinking ring 401, the side plate 406 is vertically tilted and swung through the rotating sphere 405. Therefore, the side plates 406 on both sides of the clamping ring 4 can form a limit clamp on one end of the shrinking ring 401 to prevent the shrinking ring 401 from further shrinking toward the inside of the clamping ring 4. By fixing the shrinking ring 401, the shrinking ring 401 and the clamping ring 4 as a whole can support the outside of the sealing airbag 1 to prevent the sealing airbag 1 from being unable to support the inside of the post-cast strip due to surface damage and leakage of the sealing airbag 1.
