Description

Technical Field

[0001] This utility model relates to the field of highway bridge construction technology, and more specifically, to an auxiliary device for adjusting the reinforcing bars of the side hinge joint of a hollow slab beam. Background Technology

[0002] In current highway bridge construction, prestressed hollow slab beams are widely used as a type of beam that is easy to install. During the construction of slab beam bridges, after the beams are installed, it is necessary to bend down and adjust the side reinforcement of the hollow slab beams to be horizontal within the limited space of the hinge joint. Under this construction situation, conventional construction methods are difficult, and hinge joint reinforcement adjustment auxiliary devices are usually used to adjust the side reinforcement of the hollow slab beams.

[0003] The existing hinged joint reinforcement adjustment auxiliary device works by fixing the auxiliary device itself to the existing embedded parts or other structures on the upper surface of the hollow slab beam, and then using the lever principle to adjust the side reinforcement of the slab beam to be horizontal. When there is no suitable fixing position on the upper surface of the hollow slab beam, the existing hinged joint reinforcement adjustment auxiliary device cannot be used. Utility Model Content

[0004] This utility model provides an auxiliary device for adjusting the reinforcing bars of the side hinge joint of a hollow slab beam, which can overcome some or all the defects of the prior art.

[0005] According to the present invention, an auxiliary device for adjusting the reinforcing bars of the side hinge joint of a hollow slab beam includes a device body, the device body including a working vertical rod vertically disposed in the hinge joint of an adjacent hollow slab beam, a force transmission sleeve disposed on the working vertical rod that can slide along the axial direction of the working vertical rod, and a reinforcing bar for adjusting the reinforcing bars in the hinge joint of the hollow slab beam disposed at the lower end of the force transmission sleeve.

[0006] This invention addresses the challenge of adjusting the side reinforcement bars of hollow slab beams to horizontal position within the limited space of the hinge joint after installation. The auxiliary device extends into the narrow hinge joint, using a force-transmitting sleeve that slides on the working vertical rod to move the reinforcing bar component, thus adjusting the reinforcement bars within the hinge joint. The force-transmitting sleeve can slide on the working vertical rod, and the position of the reinforcing bar component can be adjusted according to actual needs. This device is applicable to hinge joints of hollow slab beams of different sizes and shapes, demonstrating strong adaptability. Adjusting the reinforcement bars within the hinge joint using the reinforcing bar component allows for quick and accurate positioning and fixing of the reinforcement bars, reducing manual adjustment time and labor intensity, and improving construction efficiency. Furthermore, the device is disassembled and reusable, suitable for multiple construction projects, reducing construction costs and resulting in high economic benefits.

[0007] Preferably, a fixing rod perpendicular to the working vertical rod is provided horizontally in the middle of the working vertical rod, and the working vertical rod and the fixing rod form a cross shape, with the fixing rod located on the upper surface of the hollow slab beam.

[0008] This invention combines a working vertical rod with a fixed rod, with the fixed rod positioned on the upper surface of the hollow slab beam to provide support for the entire device. This eliminates the need to utilize existing structures on the hollow slab beam for device fixation, broadening its application range. The fixed rod and working vertical rod form a cross-shaped structure, increasing the device's stability and preventing tilting or shaking during operation. The fixed rod's position on the upper surface of the hollow slab beam effectively distributes stress, preventing localized stress concentration and improving the device's resistance to deformation. Once the fixed rod contacts the upper surface of the hollow slab beam, the device can be quickly positioned, reducing adjustment time and improving construction efficiency.

[0009] Preferably, the force transmission sleeve has symmetrical sliding grooves on its side along the axial direction, and the fixing rod passes through the sliding grooves and slides into the sliding grooves.

[0010] This invention utilizes a sliding groove to guide the movement of a fixed rod. The sliding groove design allows the fixed rod to slide precisely along the axial direction, ensuring a stable trajectory of the force-transmitting sleeve on the working vertical rod and preventing deviation or jamming. A symmetrical design ensures balance; the sliding grooves are symmetrically arranged along the axial direction, ensuring uniform force distribution on the force-transmitting sleeve during sliding and preventing tilting or wobbling due to uneven force distribution. The sliding fit allows for free adjustment; the sliding fit between the fixed rod and the sliding groove allows the force-transmitting sleeve to be freely adjusted according to actual needs, adapting to the adjustment requirements of hinged rebar at different heights. The sliding groove limits the range of motion of the fixed rod, preventing the force-transmitting sleeve from detaching from the working vertical rod during operation and improving the stability of the device. The cooperation between the sliding groove and the fixed rod reduces shaking during operation, ensuring the accuracy of rebar adjustment.

[0011] Preferably, the top of the force transmission sleeve is symmetrically provided with force-applying components perpendicular to the force transmission sleeve, which are used to make the force transmission sleeve slide relative to the working vertical rod.

[0012] This invention provides workers with a clear point of application for force, allowing them to apply force by stepping on it or pressing it with their hands, thus enabling the force transmission sleeve to slide along the working vertical rod. Symmetrical force application prevents skewing, as the force application components are symmetrically arranged to ensure that the force transmission sleeve is subjected to uniform force during sliding, avoiding skewing or jamming caused by uneven force. The design of the force application components allows workers to apply force by stepping on it or pressing it with their hands, making operation more labor-saving and reducing labor intensity.

[0013] Preferably, the force-applying component is an operating handle or a foot pedal.

[0014] This invention allows for the application of force through either an operating handle or a foot pedal, adapting to different construction needs. When the handle is used, it facilitates handheld operation, allowing workers to easily hold the handle and use their arm strength to push the force transmission sleeve to slide, suitable for fine adjustments and ensuring the accuracy of rebar adjustment. When the foot pedal is used, it allows workers to apply force with their feet, using their body weight to push the force transmission sleeve to slide, making operation more labor-saving and suitable for high-intensity work. In scenarios requiring greater force to adjust rebar, the foot pedal design can significantly reduce the labor intensity of workers.

[0015] Preferably, the sum of the lengths of the two fixed rods is greater than the width of the hinge joint between adjacent hollow slab beams.

[0016] With this invention, the sum of the lengths of the two fixed rods is greater than the width of the hinge joint between adjacent hollow slab beams, thus achieving cross-hinge joint support. This allows the fixed rods to cross the hinge joint and support the upper surfaces of the hollow slab beams on both sides, forming a stable support structure. Attached Figure Description

[0024] In this embodiment, after the hollow slab beam 110 is installed, the side reinforcement 120 of the hollow slab beam 110 needs to be bent downwards and adjusted to be horizontal within the limited space of the hinge joint. This auxiliary device can extend into the relatively narrow hinge joint, and the force transmission sleeve 220 slides on the working vertical rod 210, driving the pressing member 230 to move and adjust the reinforcement 120 in the hinge joint. The force transmission sleeve 220 can slide on the working vertical rod 210, and the position of the pressing member 230 can be adjusted according to actual needs. It can be applied to the hinge joints of hollow slab beams 110 of different sizes and shapes, and has strong adaptability. By adjusting the reinforcement 120 in the hinge joint through the pressing member 230, the positioning and fixing of the reinforcement 120 can be completed quickly and accurately, reducing the time and labor intensity of manual adjustment and improving construction efficiency.

[0026] In this embodiment, the working vertical rod 210 and the fixed rod 240 are combined, with the fixed rod 240 located on the upper surface of the hollow slab beam 110 to provide support for the entire device. This eliminates the need to utilize the existing structure on the hollow slab beam 110 to provide support for the device's fixation, thus broadening its application range. The fixed rod 240 and the working vertical rod 210 form a cross-shaped structure, increasing the stability of the device and preventing it from tilting or shaking during operation. The fixed rod 240, located on the upper surface of the hollow slab beam 110, can effectively distribute the force on the device, avoid local stress concentration, and improve the device's resistance to deformation. After the fixed rod 240 contacts the upper surface of the hollow slab beam 110, the device can be quickly positioned, reducing adjustment time and improving construction efficiency.

The symmetrical design ensures balance. The sliding groove 250 is symmetrically arranged along the axial direction, so that the force transmission sleeve 220 is subjected to uniform force during sliding, avoiding tilting or shaking caused by uneven force. The sliding fit enables free adjustment. The sliding fit between the fixed rod 240 and the sliding groove 250 allows the force transmission sleeve 220 to be freely adjusted in position according to actual needs, adapting to the adjustment requirements of the hinged rebar 120 at different heights. The sliding groove 250 limits the movement range of the fixed rod 240. The design of the sliding groove 250 limits the movement range of the fixed rod 240, preventing the force transmission sleeve 220 from detaching from the working vertical rod 210 during operation and improving the stability of the device. The fit between the sliding groove 250 and the fixed rod 240 reduces the shaking of the device during operation, ensuring the accuracy of the rebar 120 adjustment.

[0029] In this embodiment, the top end of the force transmission sleeve 220 is symmetrically provided with force application members 260 perpendicular to the force transmission sleeve 220. The force application members 260 are used to make the force transmission sleeve 220 slide relative to the working vertical rod 210.

[0030] In this embodiment, the force-applying component 260 provides the worker with a clear point of force application, making it easy for the worker to apply force by stepping on it or pressing it with their hands, so that the force transmission sleeve 220 slides along the working vertical rod 210; symmetrical force application avoids deflection, the force-applying component 260 is symmetrically arranged to ensure that the force transmission sleeve 220 is evenly stressed during the sliding process, avoiding deflection or jamming caused by uneven force; the design of the force-applying component 260 allows the worker to apply force by stepping on it or pressing it with their hands, making the operation more labor-saving and reducing labor intensity.

[0031] In this embodiment, the force-applying component 260 is an operating handle or a foot pedal.

[0032] In this embodiment, the force-applying component 260 can be either an operating handle or a foot pedal to adapt to different construction needs. When it is an operating handle, it facilitates hand operation, allowing workers to easily hold the handle and push the force transmission sleeve 220 to slide using their arm strength. This is suitable for fine adjustments and ensures the accuracy of the rebar 120 adjustment. When it is a foot pedal, it allows workers to apply force with their feet and use their body weight to push the force transmission sleeve 220 to slide, making the operation more labor-saving and suitable for high-intensity work. In scenarios where greater force is required to adjust the rebar 120, the foot pedal design can significantly reduce the labor intensity of workers.
