Description

Technical Field

[0001] The invention relates to the technical field of concrete pouring construction, in particular to a horizontal insertion type vibration inlet device attached to a template. Background Art

[0002] During construction, vibrating concrete is a crucial step in ensuring its quality. The primary purpose of vibrating concrete is to remove air bubbles and voids through vibration, thereby increasing its density. Failure to fully penetrate the concrete can lead to vibration leakage, which can cause uneven internal structure and insufficient strength. Therefore, during vibrating, ensure that the vibrating rod is fully inserted into the concrete to achieve optimal results.

[0003] Typically, concrete vibration in main structures is accomplished by inserting a vibrating rod vertically into the formwork from above. However, with the advancement of modern construction technology, the amount of steel used in main structures has gradually increased, and the depth and shape of the formwork have become more complex and diverse. In these situations, the traditional method of vertical vibration from above is no longer sufficient to meet construction needs. The dense arrangement of steel bars and the complex shape of the formwork affect the insertion depth of the vibrating rod, resulting in some concrete not being fully vibrated, leading to quality problems such as honeycombing and rough surfaces.

[0004] To address this issue, more advanced vibration techniques are needed, such as side vibration or bottom vibration. Side vibration involves inserting a vibrating rod into the concrete through holes in the side of the formwork. This method allows for better coverage of the concrete, ensuring uniformity and density. Bottom vibration involves vibrating from the bottom up through holes in the bottom of the formwork. This method is particularly suitable for deep or irregularly shaped concrete structures. These innovative vibration methods can effectively address problems that traditional top vibration methods cannot, thereby improving the overall quality of the concrete and ensuring the safety and durability of the building structure.

[0005] However, lateral and bottom vibrations need to cope with the pressure of concrete side and bottom leakage to avoid concrete leakage, and the current technology has not yet solved this problem well. Therefore, it is necessary to propose a more reasonable technical solution to solve the technical problems existing in the existing technology. Summary of the Invention

[0006] In order to overcome at least one of the defects mentioned above, the present invention proposes a horizontal insertion vibration inlet device attached to the formwork, which aims to facilitate the entry of the vibration device by setting an inlet device that cooperates with the formwork, vibrate from the side and bottom of the concrete casting body, and improve the quality of the casting; during the vibration process, the device can overcome the concrete pressure and avoid concrete leakage.

[0007] In order to achieve the above-mentioned purpose, the vibrating inlet device disclosed in the present invention can adopt the following technical solutions: A horizontal insertion vibrating inlet device attached to a template comprises an inner sealing membrane fitted with the template, the inner sealing membrane being provided with an opening structure for a vibrating rod to enter; a pressure-resistant sealing component is provided on the outer side of the inner sealing membrane, the pressure-resistant sealing component comprises a pressure ring connected and fixed to the template and pressing the inner sealing membrane, a plurality of sealing sheets are provided on the pressure ring, the sealing sheets are continuously laid along the circumference of the pressure ring and seal the orifice in the pressure ring; the end of the sealing sheet is connected and cooperated with the pressure ring through a sliding structure, and the sliding structure causes the sealing sheet to move back and forth along the radial direction of the pressure ring to close the opening structure or expose the opening structure.

[0008] The vibration inlet device disclosed above is attached to the side of the template. When pouring concrete, the vibration rod is extended from the outside into the concrete layer for vibration, thereby achieving uniform vibration of the concrete, expelling bubbles therein, and improving the quality of concrete construction.

[0009] Furthermore, the opening structure on the inner sealing membrane is closed under normal conditions, allowing the vibrating rod to enter and vibrate. The inner sealing membrane can adopt a variety of structures, and its structure is not limited to a single one. Here, we optimize and propose one feasible option: the opening structure on the inner sealing membrane includes a cross cut. When the vibrating rod passes through the opening structure, the cross cut opens to form a through hole. When the vibrating rod leaves the opening structure, the cross cut resets and closes. When adopting the above solution, the inner sealing membrane is made of rubber material. The inner sealing membrane formed by the reinforced material has good surface strength and can form a seal. At the same time, there is a pressure-resistant sealing component on the outside to keep the inner sealing membrane from deforming. When the vibrating rod passes through the inner sealing membrane, the cross cut fits tightly with the vibrating rod to prevent the concrete slurry from leaking out.

[0010] Furthermore, the sealing sheet structure can be constructed in a variety of forms, and is not limited to a single one. Here, we optimize and propose one feasible option: the sealing sheet is fan-shaped. When the sealing sheet seals the orifice of the pressure ring, the center of the fan-shaped circle coincides with the circle of the pressure ring. Multiple sealing sheets are laid continuously to form a circular surface. In this solution, the sealing sheets are all rigid structures, and can be made of metal plates. After splicing, they form a stable support surface to support the inner sealing membrane, thereby preventing concrete leakage.

[0011] Furthermore, the sliding structure can achieve radial movement of the sealing plate. This structure can be constructed in various forms. Here, we optimize and propose one feasible option: the sliding structure includes a sliding shaft disposed at the end of the sealing plate, and a sliding hole is provided on the pressure ring to correspond with the sliding shaft. When the sliding shaft slides axially, the sealing plate moves radially along the pressure ring. When adopting this solution, the sliding shaft can be a circular shaft, an elliptical shaft, a polygonal shaft, etc.

[0012] Furthermore, after the sliding shaft and the sliding hole are matched, axial sliding is formed. In order to maintain a stable match between the sliding shaft and the sliding hole, the match between the two is limited. Here, optimization is performed and one of the feasible options is proposed: a limiting structure is matched between the sliding shaft and the sliding hole, and the limiting structure is used to limit the sliding distance between the sliding shaft and the sliding hole.

[0013] Furthermore, the aforementioned limiting structure can adopt a variety of schemes, and its structure is not limited to a single one. Here, we optimize and propose one feasible option: the aforementioned limiting structure includes a limiting groove provided on the sliding shaft, and also includes a limiting block provided at the sliding hole and corresponding to the limiting groove; the aforementioned limiting groove extends to the end of the sliding shaft, and when the sliding shaft is fitted into the sliding hole, the limiting block snaps into the limiting groove; the end of the sliding shaft is also provided with a detachable limiting baffle to close the end of the limiting groove. When adopting the above scheme, the aforementioned limiting groove can be a square groove or an arc groove, and the aforementioned limiting baffle is connected to the sliding shaft via bolts.

[0014] Furthermore, to facilitate axial movement of the sealing plate, allowing it to be opened by a vibrating rod and laterally vibrated in the concrete, the sealing plate structure can be improved. This optimization proposes a feasible option: a guiding bevel is formed at the front end of the sealing plate. When the drill rod contacts the guiding bevel, a force is applied to the bevel, causing the sealing plate to move radially outward. When this solution is adopted, the guiding bevel can be flat or curved to facilitate the use of the vibrating rod's thrust to move the sealing plate.

[0015] Furthermore, to maintain the integrity of the support surface formed by the sealing sheets, the structure of the sealing sheets is optimized, and a feasible option is proposed: a guide structure is formed between adjacent sealing sheets. The guide structure includes a guide groove and a guide protrusion, respectively, provided on the mating surfaces of the two adjacent sealing sheets. When the two sealing sheets are aligned, the guide protrusion and the guide groove cooperate and slide relative to each other. In this solution, the sealing sheet may have a guide groove formed on one side and a guide protrusion formed on the other side; alternatively, a sealing sheet may have a guide groove formed on both sides, and adjacent sealing sheets may have guide protrusions formed on both sides. This structural arrangement strengthens the integrity of the adjacent sealing sheets, ensuring support for the inner sealing membrane even during radial movement.

[0016] Furthermore, to ensure that the sealing plate maintains its radial motion to close the pressure ring orifice, a reset structure is provided to provide a reset force to the sealing plate. This structure can be constructed in a variety of ways, and an optimization is provided herein, with one feasible option being proposed: the sliding structure is also provided with an elastic reset member, which includes a reset spring that provides an elastic restoring force to the sealing plate and moves the sealing plate toward the center of the orifice. When adopting the above solution, the number of elastic reset members is not one, but can be set to two, symmetrically arranged on both sides of the sliding shaft. In other solutions, the elastic reset member can also be combined with the sliding shaft so that the elastic reset member directly applies an elastic reset force to the sliding shaft.

[0017] Furthermore, the connection and fixing method of the pressure ring can adopt various schemes, which are not limited to a single one. Here, we optimize and propose one feasible option: the pressure ring is provided with a plurality of fasteners, which pass through the pressure ring and the inner sealing membrane and connect to the template. The sealing sheet is formed with corresponding avoidance grooves. When adopting the above scheme, the fasteners can be bolts.

[0018] Compared with the prior art, some of the beneficial effects of the technical solution disclosed in the present invention include: The present invention cooperates with the formwork through the vibration inlet device to seal the formwork laterally, thereby preventing the concrete slurry from leaking outwards, and at the same time allows the vibrating rod to extend from the side into the inside of the formwork to vibrate the concrete, helping to improve the quality of concrete pouring construction and reduce the occurrence of bubbles and the formation of honeycomb structures during concrete pouring construction.

[0030] This embodiment will be further explained below with reference to the accompanying drawings and specific examples.

[0031] In view of the fact that vertical vibration of concrete in the prior art is uneven, prone to bubbles and honeycomb structures, and difficult to perform lateral and bottom vibration, which is prone to leakage, the following embodiments optimize and overcome the shortcomings of the prior art.

[0032] Example like Figures 1 to 9 As shown, this embodiment provides a horizontal insertion type vibration inlet device attached to the template 5, including an inner sealing membrane 4 fitted with the template 5, and an opening structure 401 for the vibration rod 7 to enter is provided on the inner sealing membrane 4; a pressure-resistant sealing component is provided on the outer side of the inner sealing membrane 4, and the pressure-resistant sealing component includes a pressure ring 6 connected and fixed to the template 5 and pressing the inner sealing membrane 4, and a plurality of sealing sheets 1 are provided on the pressure ring 6, and the sealing sheets 1 are continuously laid along the circumference of the pressure ring 6 and seal the orifice in the pressure ring 6; the end of the sealing sheet 1 is connected and cooperated with the pressure ring 6 through a sliding structure, and the sliding structure causes the sealing sheet 1 to move back and forth along the radial direction of the pressure ring 6 to close the opening structure 401 or expose the opening structure 401.

[0033] The vibration inlet device disclosed in this embodiment is attached to the side of the template 5. When pouring concrete, the vibrating rod 7 is extended from the outside into the concrete layer for vibration, thereby achieving uniform vibration of the concrete, expelling bubbles therein, and improving the quality of concrete construction.

[0034] The opening structure 401 on the inner sealing membrane 4 is closed under normal conditions, allowing the vibrating rod 7 to enter and vibrate. The inner sealing membrane 4 can adopt a variety of structures, and its structure is not limited to a single one. This embodiment optimizes and adopts one of the feasible options: the opening structure 401 on the inner sealing membrane 4 includes a cross-cut. When the vibrating rod 7 passes through the opening structure 401, the cross-cut opens to form a through hole. When the vibrating rod 7 leaves the opening structure 401, the cross-cut resets and closes. When adopting the above solution, the inner sealing membrane 4 is made of rubber material. The inner sealing membrane 4 formed of the reinforced material has good surface strength and can form a seal. At the same time, there is a pressure-resistant sealing component on the outside to prevent the inner sealing membrane 4 from deforming. When the vibrating rod 7 passes through the inner sealing membrane 4, the cross-cut fits tightly with the vibrating rod 7 to prevent the concrete slurry from leaking out.

[0035] Preferably, in this embodiment, the inner sealing membrane 4 is a rubber membrane with a thickness of 10 mm.

[0036] The structure of the sealing sheet 1 can be constructed in a variety of forms and is not limited to a single one. This embodiment optimizes and adopts one feasible option: the sealing sheet 1 is fan-shaped. When the sealing sheet 1 seals the opening of the pressure ring 6, the center of the fan-shaped circle coincides with the circular shape of the pressure ring 6. Multiple sealing sheets 1 are continuously laid together to form a circular surface. When using this solution, the sealing sheets 1 are all rigid structures and can be made of metal plates. After splicing, they form a stable support surface to support the inner sealing membrane 4, thereby preventing concrete leakage.

[0037] The sliding structure enables radial movement of the sealing plate 1. This structure can be constructed in a variety of forms. This embodiment optimizes and adopts one feasible option: the sliding structure includes a sliding shaft 102 disposed at the end of the sealing plate 1. The pressure ring 6 is provided with a sliding hole corresponding to the sliding shaft 102. When the sliding shaft 102 slides axially, the sealing plate 1 moves radially along the pressure ring 6. When adopting the above solution, the sliding shaft 102 can be a circular shaft, an elliptical shaft, a polygonal shaft, etc.

[0038] After the sliding shaft 102 is matched with the sliding hole, axial sliding is formed. In order to maintain a stable match between the sliding shaft 102 and the sliding hole, the match between the two is limited. This embodiment is optimized and adopts one of the feasible options: a limiting structure is matched between the sliding shaft 102 and the sliding hole, and the limiting structure is used to limit the sliding distance between the sliding shaft 102 and the sliding hole.

[0039] The limiting structure can adopt a variety of schemes, and its structure is not limited to a single one. This embodiment optimizes and adopts one of the feasible options: the limiting structure includes a limiting groove provided on the sliding shaft 102, and also includes a limiting block provided at the sliding hole and corresponding to the limiting groove; the limiting groove extends to the end of the sliding shaft 102, and when the sliding shaft 102 is fitted into the sliding hole, the limiting block snaps into the limiting groove; the end of the sliding shaft 102 is also provided with a detachable limiting baffle to close the end of the limiting groove. When adopting the above scheme, the limiting groove can be a square groove or an arc groove, and the limiting baffle is connected to the sliding shaft 102 by bolts.

[0040] To facilitate the axial movement of the sealing piece 1, enable the sealing piece 1 to be opened under the push of the vibrating rod 7, and enable the vibrating rod 7 to enter the concrete for lateral vibration, the structure of the sealing piece 1 can be improved. This embodiment optimizes and adopts one feasible option: the front end of the sealing piece 1 forms a guiding bevel 101. When the drill rod contacts the guiding bevel 101, a force is applied to the guiding bevel 101, causing the sealing piece 1 to move radially outward. When adopting this solution, the guiding bevel 101 can be a flat surface or a curved surface to help utilize the thrust of the vibrating rod 7 to push the sealing piece 1 into action.

[0041] Preferably, the length of the guiding slope 101 formed on the sealing sheet 1 is determined according to the diameter of the vibrating rod 7 , and is at least greater than the radius of the vibrating rod 7 .

[0042] In order to maintain the integrity of the support surface formed by the sealing sheet 1, the structure of the sealing sheet 1 is optimized and one of the feasible options is adopted: a guide structure is formed between adjacent sealing sheets 1. The guide structure includes a guide groove and a guide protrusion respectively provided on the mating surfaces of the two adjacent sealing sheets 1. When the two sealing sheets 1 are adjacent to each other, the guide protrusion cooperates with the guide groove and slides relative to each other. When adopting the above solution, the guide groove is formed on one side of the sealing sheet 1, and the guide protrusion is formed on the other side; or the guide groove is formed on both sides of a sealing sheet 1, and the guide protrusion is formed on both sides of the adjacent sealing sheets 1. After the adjacent sealing sheets 1 are matched according to this structure, the integrity of the adjacent sealing sheets 1 is strengthened, and the support effect on the inner sealing membrane 4 can be guaranteed even if radial movement occurs.

[0043] In order to ensure that the sealing plate 1 forms a radial movement trend to close the orifice of the pressure ring 6, a reset structure is provided to provide a reset force to the sealing plate 1. The structure can be constructed in various forms. This embodiment is optimized and adopts one of the feasible options: the sliding structure is also provided with an elastic reset member 3, and the elastic reset member 3 includes a reset spring, which is used to provide an elastic restoring force to the sealing plate 1 and move the sealing plate 1 toward the center of the orifice. When adopting the above solution, the number of elastic reset members 3 is not one, but can be set to two, and symmetrically arranged on both sides of the sliding shaft 102; in some other solutions, the elastic reset member 3 can also be matched with the sliding shaft 102 so that the elastic reset member 3 directly applies an elastic reset force to the sliding shaft 102.

[0044] The connection and fixing method of the pressing ring 6 can adopt various schemes, which are not limited to a single scheme. This embodiment optimizes and adopts one feasible option: the pressing ring 6 is provided with a plurality of fasteners 2, which pass through the pressing ring 6 and the inner sealing membrane 4 and are connected to the template 5. The sealing sheet 1 is formed with corresponding avoidance grooves. When adopting the above scheme, the fasteners 2 can be bolts.

[0045] The above are the implementation methods listed in this embodiment, but this embodiment is not limited to the above optional implementation methods. Those skilled in the art can arbitrarily combine the above methods to obtain other various implementation methods. Anyone can derive other various implementation methods based on the inspiration of this embodiment. The above specific implementation methods should not be understood as limiting the scope of protection of this embodiment. The scope of protection of this embodiment should be based on the definition in the claims.
