Description
Technical Field
[0001] This invention relates to the technical field of building construction platforms, specifically to a construction operation structure and method for diaphragm plates in T-beams and box girders. Background Technology
[0002] Box girders and T-beams are types of beams used in bridge engineering. Box girders are hollow inside with flanges on both sides at the top, resembling a box, hence the name. They are classified as single-box or multi-box. T-beams refer to beams with a T-shaped cross-section, where the projecting parts on both sides are called flanges, and the middle part is called the beam rib (or web). During bridge construction, the joints of box girders and T-beams often require manual on-site high-altitude work. During these high-altitude operations, a construction platform is often used between the two box girders. Traditional construction platforms are mostly assembled from steel pipes or hoisted from pre-welded finished products. Using steel pipes for post-assembly increases the time workers spend working at heights and increases the risk of injury.
[0003] After studying existing finished hoisting platforms, the inventors believe that the following technical problems exist: the space between the two box girders is small, the existing hoisting platforms have limited expansion space, and they need to be expanded manually, which increases the difficulty and the risk of operation, and is not convenient for space expansion. Summary of the Invention
[0004] This invention proposes a construction operation structure for diaphragm plates in T-beams and box girders. After the installation frame is installed, the operating space can be automatically expanded, thereby increasing the operating space and improving the safety of the operation.
[0005] This application provides a construction structure for the diaphragm of a T-beam or box girder, including an installation frame, a sliding support platform on the installation frame, an extension plate lifting assembly at the bottom of the installation frame, an extension plate on the extension plate lifting assembly, and a folding extension frame rotatably connected to the installation frame via the touch assembly. It also includes a power assembly for lowering and raising the touch support platform.
[0006] By adopting the above technical solution, the touch support platform can support the operator and, during its descent to the bottom of the mounting frame, provide a force to the touch component to cause the folding extension frame to unfold and expand the operating space, eliminating the need for manual platform expansion and improving safety. As the folding extension frame gradually unfolds, the touch support platform continues to descend to the bottom of the mounting frame, pressing the extension plate to move to the side and gradually flatten it to form an overall operating platform.
[0007] Optionally, the mounting frame includes at least a base plate and four sets of uprights disposed on the base plate and perpendicular to the base plate. The uprights are provided with sliding grooves, and the touch support platform is provided with a sliding part that cooperates with the sliding grooves.
[0008] By adopting the above technical solution: after the mounting frame is installed, the sliding part of the support platform is activated and connected to the slide groove. Under the action of the power component and its own gravity, it can be lowered. During the lowering process, the folding extension frame and the flattened extension plate are gradually opened.
[0009] Optionally, the two sets of uprights are connected by a folding extension frame via a trigger assembly. The folding extension frame includes a rotating rod with one end connected to the trigger assembly, and a surrounding rod hinged to the other end of the rotating rod. The ends of the two surrounding rods on the same side of the mounting frame are hinged together.
[0010] By adopting the above technical solution: under the action of the trigger component, the rotating rod will rotate relative to the surrounding rod, causing the fence to unfold and form an integral fence.
[0011] Optionally, the extension plate lifting assembly includes a telescopic component disposed at the bottom of the mounting frame and an upright plate connected to the telescopic component, and a pull rope is provided between the upright plate and the extension plate.
[0012] By adopting the above technical solution: the upright plate is used to support the extension plate, and the pull rope can initially fix the extension plate. At the same time, when resetting, the extension plate can be pulled back, eliminating the need for manual operation.
[0013] Optionally, the actuation component includes a torque sleeve on a rotating mounting rod, the torque sleeve having a transmission groove that mates with a sliding part.
[0014] By adopting the above technical solution: the inclination direction of the transmission chute is set according to the rotation direction. Since the transmission chute is an inclined chute, during the process of the touch bearing plate descending, its sliding part moves up and down and is always inside the slide and transmission chute, thus forcing the torque sleeve to rotate, thereby achieving the rotation effect of the rotating rod.
[0015] Optionally, the power assembly includes a track fixed between adjacent T-beams or box girders and a traveling mechanism that travels on the track. The upper end of the mounting frame is connected to the traveling mechanism, and the assembly also includes a lifting mechanism for raising and lowering the touch support platform.
[0016] By adopting the above technical solution: the walking mechanism can drive the entire mounting frame to move, facilitating construction in different locations and providing ease of use. The lifting mechanism can lower and raise the support platform, facilitating height adjustment.
[0017] Optionally, the track is a grooved track with a rack at the bottom of the groove. The traveling mechanism includes a servo motor, and a gear is provided on the output shaft of the servo motor. The gear is placed inside the track and meshes with the rack.
[0018] By adopting the above technical solution, the gear can be limited by setting the grooved track, which indirectly realizes the limitation of the mounting frame. When it is necessary to change the construction position, the servo motor is controlled to move. Since the rack is fixed, the gear meshes with the rack, and the servo motor housing is connected to the mounting frame. Therefore, the servo motor will drive the mounting frame to move, thereby realizing the position change and facilitating construction.
[0019] Optionally, the lifting mechanism includes a drum rotatably connected to the top of the mounting frame and a motor that drives the drum to rotate. The drum is equipped with a wire rope, which is connected to a dynamic support platform.
[0020] By adopting the above technical solution, the lowering and lifting of the touch support platform can be achieved by using a motor to drive the drum to rotate and wind or unwind the steel wire rope.
[0021] Optionally, the bottom of the rotating rod is provided with a guide support plate.
[0022] By adopting the above technical solution: firstly, the guide support plate plays a guiding role when the extension plate is about to be flattened; secondly, it supports the extension plate after it has been flattened.
[0023] Another aspect of this application provides a method for constructing a diaphragm structure for T-beams and box girders, characterized by comprising the following steps:
[0024] S1. Fix the track on the side between the adjacent T-beams and box girders, and lower the T-beams and box girders into the gap between the T-beams and box girders to construct the diaphragm structure.
[0025] S2. Construction structure for fixed T-beams and box girder diaphragms: The gears of the traveling mechanism are placed inside the track and mesh with the rack;
[0026] S3. Lower the touch support platform. Before lowering, align the sliding part of the touch support platform with the slide groove. After lowering to a certain distance, the sliding part enters the transmission inclined groove and continues to lower and unfold the folding extension frame.
[0027] S4. The support platform continues to descend and flatten the extension plate to form an overall operating platform, after which construction work can be carried out.
[0028] By adopting the above technical solution: In the initial state, the folding extension frame is folded inside the mounting frame, which facilitates the lowering and installation of the mounting frame. After the mounting frame is lowered and fixed, the operator stands on the touch support platform and lowers the touch support platform through the power component. During the lowering process, the folding extension frame and the flattened extension plate can be automatically opened, which expands the operating area, reduces manual installation, and improves the safety of operation.
[0029] The working principle and beneficial effects of this application are as follows:
[0030] 1. The touch support platform serves two purposes: firstly, it supports the operator; secondly, as it descends to the bottom of the mounting frame, it applies a force to the touch component, causing the folding extension frame to unfold and expand the operating space, eliminating the need for manual platform expansion and improving safety. As the folding extension frame gradually unfolds, the touch support platform continues to descend to the bottom of the mounting frame, pressing the extension plate to move to the side and gradually flatten it to form the overall operating platform.
[0031] 2. After the mounting frame is installed, the sliding part of the support platform is activated and connected to the slide groove. Under the action of the power component and its own gravity, it can be lowered. During the lowering process, the folding extension frame and the flattened extension plate are gradually opened.
[0032] 3. By setting up a slotted track, the gear can be limited, which indirectly achieves the limitation of the mounting frame. When the construction position needs to be changed, the servo motor is controlled to move. Since the rack is fixed, the gear meshes with the rack, and the servo motor housing is connected to the mounting frame. Therefore, the servo motor will drive the mounting frame to move, thereby realizing the position change and facilitating construction. Attached Figure Description

Detailed Implementation
[0043] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.
[0044] like Figure 1 , Figure 2 and Figure 6 As shown, this embodiment discloses a construction structure for the diaphragm of a T-beam or box girder, including an installation frame 100. The installation frame 100 is generally rectangular in shape and is welded from circular steel pipes. In use, its length direction is parallel to the gap between the T-beam and the box girder. A touch support platform 200 is slidably mounted on the installation frame 100. The touch support platform 200 can be made of steel plate and can move up and down inside the installation frame 100. An extension plate lifting assembly 300 is provided at the bottom of the installation frame 100. An extension plate 400 is provided on the 300. The extension plate lifting assembly 300 is used to support and pull the extension plate 400. In the initial state, the extension plate 400 is in an inclined position. The mounting frame 100 is rotatably connected to the folding extension frame 600 through the touch assembly 500. It also includes a power assembly 700 for lowering and raising the touch support platform 200. In the initial state, the folding extension frame 600 is folded inside the mounting frame 100, which can reduce the overall volume and make it easy to lower the entire mounting frame 100 in narrow gaps.
[0045] In this embodiment, the touch support platform 200 serves two purposes: firstly, it supports the operator, acting as a main operating platform; secondly, as it descends to the bottom of the mounting frame 100, it applies a force to the touch component 500, causing the folding extension frame 600 to unfold, thereby expanding the operating space and eliminating the need for manual platform expansion. This also improves safety during use. As the folding extension frame 600 gradually unfolds, the touch support platform 200 continues to descend to the bottom of the mounting frame 100, pressing the extension plate 400 to move to the side and gradually flatten it to form an overall operating platform.
[0046] Reference Figure 3 In this embodiment, the mounting frame 100 includes at least a base plate 110 and four sets of uprights 120 disposed on the base plate 110 and perpendicular to the base plate 110. The base plate 110 serves two purposes: first, it can connect the uprights 120 to ensure the structural consistency of the mounting frame 100; second, it facilitates the installation of the extension plate lifting assembly 300. The uprights 120 are provided with sliding grooves 130, and the touch support platform 200 is provided with a sliding part 210 that cooperates with the sliding grooves 130.
[0047] After the mounting bracket 100 is installed, the sliding part 210 of the support platform 200 is engaged with the slide groove 130 and can be lowered under the action of the power component 700 and its own gravity. During the lowering process, the folding extension bracket 600 and the flattening extension plate 400 are gradually opened.
[0048] Reference Figure 4 and Figure 5 The basic structure and installation of the folding extension frame 600 are as follows: Two sets of uprights 120 are connected by a trigger assembly 500. The folding extension frame 600 includes a rotating rod 610 with one end connected to the trigger assembly 500, and a surrounding rod 620 hinged to the other end of the rotating rod 610. The ends of the two surrounding rods 620 on the same side of the mounting frame 100 along its length are hinged together. Under the action of the trigger assembly 500, the rotating rod 610 will rotate relative to each other, causing the surrounding rods 620 to unfold, forming a complete fence.
[0049] Reference Figure 5 The bottom of the rotating rod 610 is provided with a guide support plate 800. The guide support plate 800 serves two purposes: first, it guides the extension plate 400 when it is about to be flattened; second, it supports the extension plate 400 after it is flattened.
[0050] Looking back Figure 3To facilitate the tilting and retraction of the extension plate 400, the extension plate lifting assembly 300 in this embodiment includes a telescopic member 310 disposed at the bottom of the mounting frame 100 and an upright plate 320 connected to the telescopic member 310. A pull rope 330 is provided between the upright plate 320 and the extension plate 400. The telescopic member 310 can be a gas spring or the like, and it is best to provide two sets, which are respectively disposed at both ends of the upright plate 320. The upright plate 320 can be made of lightweight board material.
[0051] The upright plate 320 is used to support the extension plate 400. The pull rope 330 can initially fix the extension plate 400. At the same time, when resetting, it can pull the extension plate 400 to retract, eliminating the need for manual operation.
[0052] Reference Figure 6 and Figure 7 In order to provide unfolding power to the folding extension frame 600, the trigger component 500 in this embodiment includes a torque sleeve 510 on the rotating mounting rod 120. The torque sleeve 510 has a transmission groove 520 that cooperates with the sliding part 210, and the torque sleeve 510 has rotational torque.
[0053] The inclination direction of the transmission spur 520 is set according to the rotation direction requirement. Since the transmission spur 520 is an inclined groove, during the process of touching the bearing plate to descend, its sliding part 210 moves up and down and is always inside the slide 130 and the transmission spur 520, thus forcing the torque sleeve 510 to rotate, thereby achieving the rotation effect of the rotating rod 610.
[0054] Reference Figure 8 In order to move the overall mounting frame 100 and lift the touch support platform 200, a power component 700 is provided. In this embodiment, the power component 700 includes a track 710 fixed between adjacent T beams or box beams and a traveling mechanism 720 that travels on the track 710. The upper end of the mounting frame 100 is connected to the traveling mechanism 720. It also includes a lifting mechanism 730 for raising and lowering the touch support platform 200.
[0055] The traveling mechanism 720 can move the entire mounting frame 100, facilitating construction in different locations and providing ease of use. The lifting mechanism 730 can lower and raise the support platform 200, allowing for easy height adjustment.
[0056] The track is a grooved track, and a rack 711 is provided at the bottom of the groove. The walking mechanism 720 includes a servo motor 721. A gear 722 is provided on the output shaft of the servo motor 721. The gear 722 is placed inside the track and meshes with the rack 711.
[0057] By setting a slotted track, the gear 722 can be limited, which indirectly achieves the limitation of the mounting frame 100. When the construction position needs to be changed, the servo motor 721 is controlled to move. Since the rack 711 is fixed, the gear 722 meshes with the rack 711. The housing of the servo motor 721 is connected to the mounting frame 100. Therefore, the servo motor 721 will drive the mounting frame 100 to move, thereby realizing the position change and facilitating construction.
[0058] The lifting mechanism 730 includes a drum 731 rotatably connected to the top of the mounting frame 100 and a motor 732 that drives the drum 731 to rotate. A wire rope 733 is provided on the drum 731 and is connected to the active support platform 200.
[0059] The motor 732 drives the drum 731 to rotate, winding or unwinding the wire rope 733 to lower and lift the touch support platform 200.
[0060] Another aspect of this application provides a method for constructing a diaphragm structure for T-beams and box girders, characterized by comprising the following steps:
[0061] S1. Fix the track on the side between the adjacent T-beams and box girders, and lower the T-beams and box girders into the gap between the T-beams and box girders to construct the diaphragm structure.
[0062] S2. Construction structure for fixed T-beams and box girder diaphragms: The gear 722 of the traveling mechanism 720 is placed inside the track and meshes with the rack 711;
[0063] S3. Lower the touch support platform 200. Before lowering, the sliding part 210 of the touch support platform 200 is aligned with the slide groove 130. After lowering to a certain distance, the sliding part 210 enters the transmission inclined groove 520 and continues to lower and unfold the folding extension frame 600.
[0064] S4. The support platform 200 continues to descend and flatten the extension plate 400 to form an overall operating platform, after which construction work can be carried out.
[0065] In its initial state, the folding extension frame 600 is folded inside the mounting frame 100, facilitating the lowering and installation of the mounting frame 100. After the mounting frame 100 is lowered and secured, the operator stands on the touch support platform 200 and lowers the touch support platform 200 via the power component 700. During the lowering process, the folding extension frame 600 and the flattened extension plate 400 can be automatically opened, expanding the operating area, reducing manual installation, and improving operational safety.
[0066] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
