Description

Technical Field

[0001] This invention relates to the field of concrete pouring construction technology, specifically to a horizontally inserted vibratory inlet device with attached formwork. Background Technology

[0002] In the construction process, a crucial step in ensuring concrete quality is vibration. The main purpose of vibration is to eliminate air bubbles and voids in the concrete, making it more compact. If the vibrator is not fully inserted into the concrete, it may lead to incomplete vibration, resulting in uneven internal structure and insufficient strength. Therefore, when performing vibration, it is essential to ensure that the vibrator is fully inserted into the designated position in the concrete to achieve the best vibration effect.

[0003] Typically, concrete compaction in the main structure is achieved by vertically inserting a vibrator into the formwork from above. However, with the development of modern construction technology, the amount of reinforcing steel used in the main structure has gradually increased, and the depth and shape of the formwork have become more complex and diverse. In this situation, the traditional vertical vibration method can no longer meet construction requirements. The dense arrangement of reinforcing steel and the complex shape of the formwork affect the insertion depth of the vibrator, causing some concrete to not be fully compacted, thus leading to quality problems such as honeycombing and pitting.

[0004] To address this issue, more advanced vibration techniques are needed, such as lateral vibration or bottom vibration. Lateral vibration involves setting vibration holes on the sides of the formwork, through which a vibrator is inserted into the concrete for compaction. This method provides better coverage of all corners of the concrete, ensuring uniformity and density. Bottom vibration, on the other hand, involves setting vibration holes at the bottom of the formwork, vibrating from the bottom up. This method is particularly suitable for deep or irregularly shaped concrete structures. These innovative vibration methods effectively solve problems that traditional top-compaction methods cannot address, thereby improving the overall quality of the concrete and ensuring the safety and durability of the building structure.

[0005] However, lateral and bottom vibration require addressing the pressure of concrete leakage at the sides and bottom to prevent concrete leaks, a problem that current technologies have not yet adequately solved. Therefore, a more reasonable technical solution is needed to address the existing technical issues. Summary of the Invention

[0006] To overcome at least one of the aforementioned defects, this invention proposes a horizontally inserted vibratory inlet device with an attached template. The aim is to facilitate the entry of the vibratory device by setting an inlet device that cooperates with the template, so as to vibrate from the side and bottom of the concrete pouring body and improve the quality of the pouring. During the vibration process, this device can overcome the concrete pressure and avoid concrete leakage.

[0007] To achieve the above objectives, the vibratory inlet device disclosed in this invention can adopt the following technical solution: A transverse vibratory inlet device with an attached template includes an inner sealing membrane that fits into the template, with an opening structure on the inner sealing membrane for a vibrator to enter; an anti-compression sealing assembly is provided on the outer side of the inner sealing membrane, the anti-compression sealing assembly includes a pressure ring that is connected and fixed to the template and presses the inner sealing membrane, and a plurality of sealing sheets are provided on the pressure ring, the sealing sheets being continuously laid along the circumference of the pressure ring and sealing the openings inside the pressure ring; the ends of the sealing sheets are connected and engaged with the pressure ring through a sliding structure, the sliding structure causing the sealing sheets 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 aforementioned vibratory inlet device, by attaching to the side of the formwork, allows the vibrator to be inserted into the concrete layer from the outside during concrete pouring, thereby achieving uniform vibration of the concrete, expelling air bubbles, and improving the quality of concrete construction.

[0009] Furthermore, the opening structure on the inner sealing membrane is normally closed, allowing the vibrator to enter and vibrate. The inner sealing membrane can employ various 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-shaped cut. When the vibrator passes through the opening structure, the cross-shaped cut opens to form a through hole; when the vibrator leaves the opening structure, the cross-shaped cut closes. In this scheme, the inner sealing membrane is made of rubber material, and the inner sealing membrane formed with reinforcing material has good surface strength, enabling it to form a seal. Simultaneously, there is a pressure-resistant sealing component on the outside to keep the inner sealing membrane from deforming. When the vibrator passes through the inner sealing membrane, the cross-shaped cut tightly adheres to the vibrator, preventing concrete slurry leakage.

[0010] Furthermore, the structure of the sealing sheet can be constructed in various 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 closes the orifice of the pressure ring, the center of the fan shape coincides with the circle of the pressure ring, and multiple sealing sheets are continuously laid to form a circular surface. When using the above scheme, 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 enables radial movement of the sealing sheet. Its structure can be constructed in various forms; here, we optimize and propose one feasible option: the sliding structure includes a sliding shaft located at the end of the sealing sheet, and a sliding hole corresponding to the sliding shaft is provided on the pressure ring. When the sliding shaft slides axially, the sealing sheet moves radially along the pressure ring. In this scheme, the sliding shaft can be a round shaft, an elliptical shaft, a polygonal shaft, etc.

[0012] Furthermore, after the sliding shaft and the sliding hole are engaged, axial sliding is formed. In order to maintain a stable engagement between the sliding shaft and the sliding hole, the engagement between the two is limited. Here, optimization is proposed and one feasible option is suggested: the sliding shaft and the sliding hole are engaged with a limiting structure, which is used to limit the sliding distance between the sliding shaft and the sliding hole.

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

[0014] Furthermore, to facilitate the axial movement of the sealing strip and enable it to open under the push of the vibrator, allowing the vibrator to enter the concrete for lateral vibration, the structure of the sealing strip can be improved. Here, we propose one feasible option: the front end of the sealing strip forms a guide slope. When the vibrator contacts the guide slope, it applies a force to the guide slope, causing the sealing strip to move radially outward. In this scheme, the guide slope can be either a plane or a curved surface, used to facilitate the movement of the sealing strip by the thrust of the vibrator.

[0015] Furthermore, to maintain the integrity of the supporting surface formed by the sealing sheet, the structure of the sealing sheet is optimized, and one feasible option is proposed: a guide structure is formed between adjacent sealing sheets. The guide structure includes guide grooves and guide protrusions respectively provided on the mating surfaces of the two adjacent sealing sheets. When the two sealing sheets are adjacent and mated, the guide protrusions engage with the guide grooves and slide relative to each other. With the above scheme, a guide groove is formed on one side of the sealing sheet, and a guide protrusion is formed on the other side; or, guide grooves are formed on both sides of a sealing sheet, and guide protrusions are formed on both sides of adjacent sealing sheets. With this structure, the integrity of adjacent sealing sheets is stronger, and even with radial movement, the support effect on the inner sealing membrane can be guaranteed.

[0016] Furthermore, to ensure the sealing sheet's radial tendency to close the pressure ring orifice, a reset structure is provided to provide a reset force to the sealing sheet. This structure can be constructed in various forms; here, we optimize and propose one feasible option: the sliding structure also includes an elastic reset element, which comprises a reset spring. The reset spring provides an elastic restoring force to the sealing sheet, causing it to move towards the center of the orifice. When using the above scheme, the number of elastic reset elements is not limited to one; it can be two, symmetrically arranged on both sides of the sliding shaft. In other schemes, the elastic reset element can also cooperate with the sliding shaft, allowing the elastic reset element to directly apply an elastic reset force to the sliding shaft.

[0017] Furthermore, the connection and fixing method of the pressure ring can adopt various schemes and is not limited to one. Here, we optimize and propose one feasible option: the pressure ring is provided with several fasteners, which pass through the pressure ring and the inner sealing membrane and are connected to the template. Corresponding clearance grooves are formed on the sealing sheet. 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 this invention include: This invention uses a vibratory inlet device in conjunction with a template to laterally seal the template, preventing concrete slurry from leaking outwards. At the same time, it allows the vibrator to extend from the side into the inside of the template to vibrate the concrete, helping to improve the quality of concrete pouring and reducing the occurrence of air bubbles and honeycomb structures during concrete pouring.

[0030] The following description, in conjunction with the accompanying drawings and specific embodiments, further illustrates this embodiment.

[0031] To address the issues of uneven compaction, air bubbles, and honeycomb structures in existing vertical concrete vibration techniques, as well as the difficulty and potential leakage issues associated with lateral and bottom vibration, the following embodiments optimize and overcome the shortcomings of existing technologies.

[0032] Example like Figures 1-9As shown, this embodiment provides a horizontally inserted vibratory inlet device with an attached template 5, including an inner sealing membrane 4 that fits into the template 5. The inner sealing membrane 4 has an opening structure 401 for the vibrator 7 to enter. An anti-compression sealing component is provided on the outer side of the inner sealing membrane 4. The anti-compression sealing component includes a pressure ring 6 that is connected and fixed to the template 5 and presses the inner sealing membrane 4. A plurality of sealing sheets 1 are provided on the pressure ring 6. The sealing sheets 1 are continuously laid along the circumference of the pressure ring 6 and seal the openings inside the pressure ring 6. The ends of the sealing sheets 1 are connected and cooperated with the pressure ring 6 through a sliding structure. The sliding structure causes the sealing sheets 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. During concrete pouring, the vibrator 7 is inserted into the concrete layer from the outside to vibrate, thereby achieving uniform vibration of the concrete, expelling air bubbles and improving the quality of concrete construction.

[0034] The opening structure 401 on the inner sealing membrane 4 is normally closed, allowing the vibrator 7 to enter and vibrate. The inner sealing membrane 4 can have various structures, and its structure is not limited to a single one. This embodiment optimizes and adopts one feasible option: the opening structure 401 on the inner sealing membrane 4 includes a cross-shaped cut. When the vibrator 7 passes through the opening structure 401, the cross-shaped cut opens to form a through hole; when the vibrator 7 leaves the opening structure 401, the cross-shaped cut closes. In this configuration, the inner sealing membrane 4 is made of rubber material. The inner sealing membrane 4 formed with reinforcing material has good surface strength and can form a seal. Simultaneously, there is a pressure-resistant sealing component on the outside to keep the inner sealing membrane 4 from deforming. When the vibrator 7 passes through the inner sealing membrane 4, the cross-shaped cut tightly fits the vibrator 7, preventing concrete slurry leakage.

[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 various 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 closes the orifice of the pressure ring 6, the center of the fan shape coincides with the circle of the pressure ring 6, and multiple sealing sheets 1 are continuously laid to form a circular surface. When the above scheme is adopted, 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 sheet 1. Its structure can be constructed in various forms; this embodiment optimizes and adopts one feasible option: the sliding structure includes a sliding shaft 102 disposed at the end of the sealing sheet 1, and a sliding hole corresponding to the sliding shaft 102 is provided on the pressure ring 6. When the sliding shaft 102 slides axially, the sealing sheet 1 moves radially along the pressure ring 6. When using the above scheme, the sliding shaft 102 can be a round shaft, an elliptical shaft, a polygonal shaft, etc.

[0038] After the sliding shaft 102 is engaged with the sliding hole, axial sliding is formed. In order to maintain the stable engagement between the sliding shaft 102 and the sliding hole, the engagement between the two is limited. This embodiment optimizes and adopts one feasible option: the sliding shaft 102 and the sliding hole are engaged with a limiting structure. 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 various schemes, and its structure is not limited to a single one. This embodiment optimizes and adopts one feasible option: the limiting structure includes a limiting groove disposed on the sliding shaft 102, and a limiting block disposed at the sliding hole and correspondingly cooperating with 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 is engaged in the limiting groove; the end of the sliding shaft 102 is also provided with a detachable limiting baffle to close the port of the limiting groove. When adopting the above scheme, the limiting groove can be a square groove or an arc groove, etc., and the limiting baffle is connected to the sliding shaft 102 by bolts.

[0040] To facilitate the axial movement of the sealing plate 1 and enable it to open under the push of the vibrator 7, allowing the vibrator 7 to enter the concrete for lateral vibration, the structure of the sealing plate 1 can be improved. This embodiment optimizes and adopts one feasible option: the front end of the sealing plate 1 forms a guide slope 101. When the vibrator 7 contacts the guide slope 101, it applies a force to the guide slope 101, causing the sealing plate 1 to move radially outward. In this scheme, the guide slope 101 can be a plane or a curved surface, used to help utilize the thrust of the vibrator 7 to move the sealing plate 1.

[0041] Preferably, the length of the guide 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] To maintain the integrity of the supporting surface formed by the sealing sheet 1, the structure of the sealing sheet 1 is optimized, and one feasible option is adopted: a guide structure is formed between adjacent sealing sheets 1. The guide structure includes guide grooves and guide protrusions respectively provided on the mating surfaces of the two adjacent sealing sheets 1. When the two sealing sheets 1 are adjacent and mated, the guide protrusions engage with the guide grooves and slide relative to each other. With the above scheme, a guide groove is formed on one side of the sealing sheet 1 and a guide protrusion is formed on the other side; or guide grooves are formed on both sides of a sealing sheet 1, and guide protrusions are formed on both sides of adjacent sealing sheets 1. After the mating with this structure, the integrity of the adjacent sealing sheets 1 is stronger, and the supporting effect on the inner sealing membrane 4 can be guaranteed even if radial movement occurs.

[0043] To ensure the sealing sheet 1 forms a closed pressure ring 6 orifice in the radial direction, a reset structure is provided to provide a reset force to the sealing sheet 1. This structure can be constructed in various forms; this embodiment optimizes and adopts one feasible option: an elastic reset element 3 is also provided at the sliding structure. The elastic reset element 3 includes a reset spring, which provides an elastic restoring force to the sealing sheet 1 and moves the sealing sheet 1 towards the center of the orifice. When using the above scheme, the number of elastic reset elements 3 is not limited to one; it can be two, symmetrically arranged on both sides of the sliding shaft 102. In other schemes, the elastic reset element 3 can also cooperate with the sliding shaft 102, allowing the elastic reset element 3 to directly apply an elastic reset force to the sliding shaft 102.

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

[0045] The above are the embodiments listed in this example. However, this example is not limited to the optional embodiments described above. Those skilled in the art can arbitrarily combine the above methods to obtain other various embodiments. Anyone can derive other various forms of embodiments under the guidance of this example. The above specific embodiments should not be construed as limiting the scope of protection of this example. The scope of protection of this example should be defined in the claims.
