Description

Technical Field

[0001] This utility model relates to the technical field of building construction, and in particular to an adjustable beam and column reinforcement protective layer control device. Background Technology

[0002] In traditional construction projects, the installation of ALC partition panels mainly relies on manual operation and simple tools (such as threaded steel crowbars and fixed support frames), which has significant technical limitations. Specifically:

[0003] Insufficient adjustment precision: Traditional tools lack multi-dimensional adjustment functions, making it difficult to achieve precise control of the installation angle and position of wall panels. This results in installation deviations generally exceeding ±5mm, requiring repeated manual adjustments and leading to low construction efficiency.

[0004] High risk of damage: The contact surface of tools such as crowbars is narrow (usually ≤10cm²), and the local pressure concentration can easily cause gaps or cracks on the wall panel surface, affecting the overall quality of the wall.

[0005] Adaptability limitations: The existing support structure is fixed and cannot adapt to the installation requirements of irregular walls, curved structures or areas with dense reinforcement (such as bridge piers, transfer beam joints, etc.), especially in complex parts such as beam-column intersections and curved formwork, it is difficult to penetrate multiple layers of steel mesh for fixation.

[0006] Poor economic efficiency: Traditional tools are mostly disposable or easily damaged, with weak resistance to concrete impact. They need to be replaced frequently during long-term construction, resulting in high material consumption and maintenance costs.

[0025] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0026] The following is in conjunction with the appendix Figure 1-3 The present invention will be described in further detail below.

[0027] This utility model discloses an adjustable beam and column reinforcement protective layer control device.

[0028] Reference Figures 1-3 An adjustable beam / column reinforcement protective layer control device includes a telescopic rod assembly and a reinforcement positioning assembly fixed to the telescopic rod assembly. The telescopic rod assembly is telescopic along its own length and is provided with an adjustment and locking mechanism for locking the length of the telescopic rod assembly. The telescopic rod assembly is used to support both sides of the beam / column reinforcement 8 to maintain a set distance from the formwork 6.

[0029] This technical solution, through the adjustability and locking function of the telescopic rod assembly, can precisely control the spacing between the beam / column reinforcing bars 8 and the formwork 6, effectively solving the problem of insufficient adjustment precision of traditional tools. Simultaneously, the design of the reinforcing bar positioning assembly avoids damage to the reinforcing bar surface, improving construction quality. Compared with existing technologies, this device has higher adaptability and economy, can meet the needs of complex construction environments, and reduces material waste and maintenance costs.

[0030] The telescopic rod offers precise control, adaptability to complex joints, rapid installation, reduced manual adjustment time, strong resistance to concrete impact, high economic efficiency, reusability, and low long-term cost. It is suitable for large-section beams and columns, as well as irregular structural joints, such as bridge piers, transfer beams, and other areas with dense reinforcement. The telescopic rod can penetrate multiple layers of steel mesh for overall fixation and can be flexibly adjusted in complex locations such as beam-column intersections and curved walls to adapt to curved formwork.

[0031] In this embodiment, the telescopic rod assembly includes at least three telescopic rods connected in sequence. Two telescopic rods are located on the lateral sides of the template 6, and one telescopic rod is located on the top of the beam / column reinforcement 8. The telescopic rods are placed between the template 6 and the beam / column reinforcement 8, so that the template 6 and the beam / column reinforcement 8 maintain a set distance.

[0032] Specifically, the expansion joint assembly, with its three expansion joints, effectively supports the sides and top of the beam / column reinforcement 8, ensuring that the spacing between the reinforcement and the formwork 6 meets design requirements. The expansion joints on the lateral sides of the formwork 6 fix the lateral position of the reinforcement, while the top expansion joint controls the vertical position of the reinforcement. The expansion joints are connected by connectors 5, allowing the entire assembly to be flexibly adjusted in length to accommodate beam / column reinforcement 8 of different sizes.

[0033] The telescopic rod employs a nested hollow tube structure, with its length fixed by an adjustable locking mechanism. For example, the adjustable locking mechanism may include a sleeve; a sleeve is mounted on hollow tube 1, and hollow tube 2 is threadedly connected to the sleeve. Length adjustment and locking are achieved by rotating hollow tube 2. Alternatively, the adjustable locking mechanism may include a pin body and an elastic element. Hollow tube 2 3 has multiple pin holes 4 along its length. The pin body slides on hollow tube 1, and the elastic element applies a preload force to the pin body in the direction of the pin holes 4, causing the pin body to engage with the corresponding pin hole 4, thus achieving quick locking of the telescopic rod.

[0034] By employing a multi-telescopic rod arrangement and an adjustable locking mechanism, the spacing between the beam / column reinforcement 8 and the formwork 6 can be precisely controlled, solving the problems of insufficient adjustment precision and limited adaptability of traditional tools. Compared with existing technologies, this solution not only improves construction efficiency but also reduces the frequency of manual adjustments and lowers the risk of damage during construction.

[0035] In this embodiment, the telescopic rod includes two nested hollow tubes 1 and 3, with their ends supporting the two sides of the beam / column reinforcement 8 respectively. The nested design of the hollow tubes 1 and 3 allows the length of the telescopic rod to be adjusted according to actual needs, thus accommodating beam / column reinforcement 8 of different sizes. Specifically, the hollow tubes 1 and 3 can move relative to each other by sliding or rotating to achieve the telescopic function. As a preferred embodiment, a locking mechanism can be provided between the hollow tubes 1 and 3 to ensure that they are fixed in position after adjustment, preventing displacement during use.

[0036] Therefore, this technical solution achieves adjustable length of the telescopic rod through the design of two nested hollow tubes, thus flexibly adapting to beam / column reinforcement bars of different sizes, solving the problem that traditional fixed-length support devices cannot meet diverse construction needs. Compared with existing technologies, this solution not only improves construction flexibility and efficiency but also reduces installation deviations and repeated adjustments caused by size mismatches. Furthermore, the nested structure design minimizes the space occupied by the telescopic rod in its retracted state, facilitating transportation and storage, further enhancing construction convenience.

[0037] In this embodiment, the adjustment mechanism includes a sleeve. A sleeve is mounted on hollow tube 1, and hollow tube 2 is threadedly connected to the sleeve. The sleeve, as the core component of the adjustment mechanism, achieves relative position adjustment between hollow tube 1 and hollow tube 2 3 through a threaded connection. Specifically, the sleeve can be designed with an internal thread structure, and the outer surface of hollow tube 2 3 has a matching external thread. By rotating the sleeve or hollow tube 2 3, the extension and retraction of hollow tube 2 3 within hollow tube 1 can be achieved. As a preferred embodiment, the sleeve can be made of a high-strength alloy material to improve its wear resistance and service life. Furthermore, the internal thread of the sleeve can be designed with a self-locking structure to prevent loosening of the thread due to vibration or other external forces during use, thereby ensuring the stability of the adjusted position.

[0038] Therefore, this technical solution achieves precise adjustment and locking of the telescopic rod assembly length through a combination of sleeve and threaded connection. Compared with existing technologies, this solution has advantages such as simple operation, high adjustment accuracy, and good stability. Specifically, the threaded connection avoids the problem of insufficient adjustment accuracy caused by the pin hole spacing limitation in traditional pin-type adjustment mechanisms. Simultaneously, the self-locking structure of the sleeve effectively prevents positional shift after adjustment, ensuring that the spacing between the beam / column reinforcement and the formwork 6 always remains at the set value. Therefore, this technical solution can effectively improve construction efficiency, reduce the number of manual adjustments, and reduce construction quality problems caused by improper adjustment in practical applications.

[0039] In this embodiment, the adjustment mechanism includes a pin body and an elastic element. The hollow tube 2 3 has multiple pin holes 4 along its length. The pin body is slidably disposed on the hollow tube 1. The elastic element is used to apply a pre-tightening force to the pin body in the direction of the pin hole 4, so that the pin body is engaged with the corresponding pin hole 4.

[0040] Specifically, the pin body is slidably mounted inside the hollow tube 1 and can move along the length of the hollow tube 1. Multiple pin holes 4 are evenly distributed along the length of the hollow tube 3. Under the preload of the elastic element, the pin body automatically engages with the corresponding pin hole 4, thereby fixing the length of the telescopic rod. The elastic element is a spring, ensuring that the pin body is stably engaged in the pin hole 4, preventing loosening. One end of the pin body protrudes from the hollow tube 1, facilitating user movement of the pin body. As a preferred embodiment, the end of the pin body can be designed as tapered or spherical to facilitate insertion into the pin hole 4 and reduce friction. Furthermore, the diameter and spacing of the pin holes 4 can be adjusted according to actual needs to meet different length adjustment requirements.

[0041] Therefore, this technical solution, through the cooperation of the pin body and the pin hole 4, achieves rapid adjustment and fixation of the telescopic rod length, solving the problems of complex operation and insufficient precision of traditional adjustment mechanisms. Compared with existing technologies, this solution has a simpler structure, a more convenient adjustment process, and can effectively avoid loosening or failure caused by improper adjustment, thus improving the stability and reliability of the device.

[0042] In this embodiment, the end of the telescopic rod is provided with a connector 5 for connecting with the end of an adjacent telescopic rod. The connector 5 can be an L-shaped connecting plate, or it can be designed as a rotatable structure to adjust the angle of the telescopic rod during connection, such as a universal joint with a locking function, which is prior art.

[0043] Therefore, this technical solution, by setting the connector 5, not only simplifies the connection process between adjacent expansion joints but also improves the stability and reliability of the connection, significantly enhancing construction efficiency and reducing construction errors caused by unstable connections. Furthermore, the connector 5 has a simple structure, is easy to manufacture and maintain, and possesses good economic efficiency and practicality.

[0044] In this embodiment, the telescopic rod is integrated with a level calibrator or laser positioning module to monitor the levelness and verticality of the steel mesh.

[0045] The integration of a leveling device or laser positioning module can be achieved through fixed brackets or embedded installation. Fixed brackets securely mount the leveling device or laser positioning module at a specific location on the telescopic pole, ensuring it does not shift during construction. The leveling device can be a bubble level or an electronic level. A bubble level determines levelness by observing the position of the bubble, while an electronic level provides real-time level data via sensors. The laser positioning module measures the verticality of the reinforcing mesh by emitting a laser beam. The emission angle and position of the laser beam can be fine-tuned via an adjustment mechanism to adapt to different construction needs.

[0046] Specifically, the integration of a level calibrator or laser positioning module enables real-time monitoring of the horizontal and vertical alignment of the reinforcing mesh during construction, ensuring that the mesh's position meets design requirements. The level calibrator detects the horizontal state of the expansion joints, promptly identifying and correcting any tilting issues with the reinforcing mesh. The laser positioning module, by emitting a laser beam, measures the verticality of the reinforcing mesh from both sides or the top, ensuring consistent spacing between the mesh and the formwork 6. This integrated approach not only improves construction accuracy but also reduces the frequency of manual adjustments, thereby increasing construction efficiency.

[0047] By integrating a level calibrator or laser positioning module onto the telescopic pole, real-time monitoring of the horizontal and vertical alignment of the reinforcing mesh is achieved, solving the problem of accurately controlling the position of the reinforcing mesh in traditional construction. Compared with existing technologies, this solution has advantages such as high measurement accuracy, ease of operation, and strong adaptability, effectively improving construction quality and efficiency.

[0048] In this embodiment, the rebar positioning component is a U-shaped groove or an elastic clamping claw, with an anti-slip rubber layer or nylon buffer pad on its inner side. The U-shaped groove clamps the rebar through its open end, while the elastic clamping claw secures the rebar through elastic deformation. The anti-slip rubber layer or nylon buffer pad effectively increases the friction between the rebar and the clamping claw, preventing slippage or displacement during construction and reducing damage to the rebar surface.

[0049] Specifically, the U-shaped slot design allows it to accommodate rebars of different diameters. By adjusting the slot opening width, rebars of different specifications can be secured. The elastic clamping claws, through their elastic properties, automatically adapt to the shape of the rebar and provide continuous clamping force during the clamping process, ensuring the stability of the rebar. The thickness and material of the anti-slip rubber layer or nylon cushioning pad can be adjusted according to actual needs to provide optimal anti-slip effect and cushioning performance.

[0050] By employing U-shaped slots or elastic clamping claws as rebar positioning components, combined with an anti-slip rubber layer or nylon buffer pad design, the problem of slippage or displacement that easily occurs in traditional rebar positioning devices during construction is effectively solved, while reducing damage to the rebar surface. Compared with existing technologies, this solution has higher stability and adaptability, can meet the needs of different construction environments, and improves construction efficiency and quality.

[0051] In this embodiment, a concrete spacer 7 is provided between the bottom of the beam and column reinforcement and the formwork 6. The main function of the concrete spacer 7 is to ensure a certain distance between the beam and column reinforcement and the formwork 6, so that the reinforcement can be fully wrapped during concrete pouring, avoiding direct contact between the reinforcement and the formwork 6, and preventing problems such as reinforcement corrosion or insufficient concrete cover. The concrete spacer 7 is usually made of high-strength concrete, which has good compressive strength and durability, and can withstand the pressure of concrete pouring without deformation or damage. In addition, the shape and size of the concrete spacer 7 can be adjusted according to specific construction needs to adapt to different beam and column reinforcement arrangements and formwork 6 structures.

[0052] By setting concrete spacers 7, the problem of inaccurate spacing control between beam and column reinforcement and formwork 6 is effectively solved, ensuring that the concrete cover thickness of the reinforcement meets design requirements. Compared with existing technologies, this solution not only improves construction accuracy but also reduces the risk of reinforcement corrosion caused by direct contact between the reinforcement and formwork 6, while simplifying the construction process and improving construction efficiency.

[0053] In this embodiment, a concrete spacer 7 is provided between the bottom of the beam / column reinforcement 8 and the formwork 6. The concrete spacer 7 is used to support the beam / column reinforcement 8, ensuring that it maintains a set distance from the formwork 6, thereby preventing direct contact between the reinforcement and the formwork 6 and preventing displacement or deformation of the reinforcement during concrete pouring. The material of the concrete spacer 7 is usually high-strength concrete to ensure that it can withstand the weight of the reinforcement and concrete, while having good durability and compressive strength.

[0054] In a preferred embodiment, the concrete spacer 7 can be fixedly connected to the formwork 6 by pre-embedded bolts or a snap-fit ​​structure to ensure that it will not shift due to vibration or external forces during construction. At the same time, the installation position of the spacer should be accurately measured and positioned to ensure that the spacing between the reinforcing bars and the formwork 6 meets the design requirements, avoiding any impact on the quality of concrete pouring due to excessively large or small spacing.
