Description

Technical Field

[0001] This application relates to the field of building engineering technology, and in particular to a Bailey panel assembly base. Background Technology

[0002] Bailey bridge panels, also known as Bailey bridge frames, are a type of prefabricated steel bridge structure. They can be quickly assembled and disassembled, making them suitable for complex terrain or emergency scenarios.

[0003] When assembling existing Bailey bridge panels at height, a crane is first used to hoist the panels to the installation location. Then, workers manually adjust the spacing between the Bailey bridge panels to be installed and the already moved panels. Next, connecting plates are used to move the Bailey bridge panels to be installed onto the already moved panels. Finally, the crane hook is removed from the Bailey bridge panels to combine the panels into a Bailey beam.

[0004] However, since each Bailey panel requires a crane to suspend it in the air for an extended period during installation, workers cannot install multiple Bailey beams simultaneously when there are insufficient cranes at the construction site or when there is a lack of suitable space for a sufficient number of cranes to work at the same time.

[0005] In view of this, there is a need to provide a Bailey plate assembly base. Utility Model Content

[0006] To address the issue that existing Bailey bridge installations require prolonged crane operation, and that insufficient crane availability at the construction site hinders the maximization of installation efficiency, this application provides a Bailey bridge assembly base.

[0007] This application provides a Bailey panel assembly base, which adopts the following technical solution: it includes a base, a fixed frame and a movable frame, wherein the base is disposed on the surface to be constructed;

[0008] The fixing frame is fixedly connected to the side of the base away from the surface to be constructed, and the fixing frame is detachably connected to the Bailey panel;

[0009] The movable frame is slidably connected to the side of the base away from the surface to be constructed and is detachably connected to the Bailey panel. The movable frame can move the Bailey panel on the movable frame closer to or further away from the Bailey panel on the fixed frame along the length direction of the base.

[0010] By adopting the above technical solution, when assembling Bailey panels into Bailey beams on a horizontal or inclined construction surface, workers can pre-fix the Bailey panel assembly base to the construction surface. Then, a crane can be used to lift two Bailey panels one after the other and install them on a fixed frame and a movable frame respectively. Next, workers can slide the movable frame according to the model of the connecting plates used until the distance between the two Bailey panels meets the usage requirements of these connecting plates. Then, multiple connecting plates are connected to the two Bailey panels in sequence with bolts and nuts. This allows the Bailey panel assembly base to install connecting plates without the need for a crane to suspend the Bailey panels during the installation of connecting plates. This enables the construction site to install connecting plates on multiple Bailey panel assembly bases simultaneously without being limited by the number of cranes, thus maximizing the installation efficiency of the Bailey panels.

[0011] Specifically, the fixing frame includes a fixing plate, a fixing rod, and a fixing hook. One side of the fixing plate is connected to the base, one end of the fixing rod is connected to the other side of the fixing plate, and the other end of the fixing rod has a fixing slot along the length of the base. The hook handle of the fixing hook is detachably connected to the inner wall of the fixing slot, and the hook tip of the fixing hook extends out of the fixing slot from the opening on the side of the fixing slot near the movable frame. The Bailey panel includes a pair of main beams and multiple crossbeams. The pair of main beams are arranged in parallel and spaced apart. One end of each of the multiple crossbeams is connected to one of the two main beams, and the other end of each of the multiple crossbeams is connected to the other of the two main beams. The main beams have a hanging groove, and the hook tip of the fixing hook can be inserted into the hanging groove and abut against the two main beams between the fixing hook and the fixing plate.

[0012] The movable frame includes a movable plate, a movable rod, and a movable hook. A slide rail is provided on the base along its own length. A slider adapted to the slide rail is provided on one side of the movable plate, and the movable plate is slidably connected to the slide rail via the slider. One end of the movable rod is connected to the side of the movable plate away from the slider. A movable through groove is opened on the other end of the movable rod along the length of the base. The hook handle of the movable hook is detachably connected to the inner wall of the movable through groove. The hook tip of the movable hook extends out of the movable through groove from the opening on the side of the movable through groove near the fixed frame. The hook tip of the movable hook can be inserted into the hanging groove and abut against the two main beams between the movable hook and the movable plate.

[0013] By adopting the above technical solution, workers can quickly connect the Bailey panel to the fixed frame by inserting the hook tip of the fixed hook into the mounting slot of one Bailey panel and placing the Bailey panel between the fixed hook and the fixed plate; workers can also quickly connect the Bailey panel to the moving frame by inserting the hook tip of the moving hook into the mounting slot of another Bailey panel and placing the Bailey panel between the moving hook and the moving plate.

[0014] Furthermore, the fixing frame also includes a fixing diagonal brace, one end of which is connected to the fixing plate, and the other end of which is connected to the side of the fixing rod away from the movable frame.

[0015] The movable frame also includes a movable diagonal brace, one end of which is connected to the movable plate, and the other end of which is connected to the side of the movable rod away from the fixed frame.

[0016] By adopting the above technical solutions, the fixed diagonal brace can strengthen the connection between the fixed rod and the fixed plate; the movable diagonal brace can strengthen the connection between the movable rod and the movable plate.

[0017] Furthermore, a fixing block is provided on the side of the fixing plate away from the base, one of the two main beams is provided with the hanging groove, and the other of the two main beams is provided with the snap-fit ​​groove. The fixing block can be inserted into the snap-fit ​​groove and the two main beams abut against the fixing block and the fixing hook.

[0018] A movable block is provided on the side of the movable plate away from the base. The movable block can be inserted into the snap-fit ​​groove and the two main beams abut against the movable block and the movable hook.

[0019] By adopting the above technical solution, the fixed block can cooperate with the fixed hook to connect the Bailey panel, so that the connection between the Bailey panel and the fixed frame is more stable; the movable block can cooperate with the movable hook to connect the Bailey panel, so that the connection between the Bailey panel and the movable frame is more stable.

[0020] Furthermore, a sliding groove is provided on the side of the slider away from the movable frame, the slide rail is inserted into the sliding groove, an abutment strip is provided on the side wall of the slide rail along its own length, an abutment protrusion is provided at the opening of the sliding groove, and the side of the abutment protrusion near the movable frame can abut against the abutment strip.

[0021] By adopting the above technical solution, when the base is set on an inclined surface to be constructed, the abutment strip can abut against the abutment protrusion and restrict the slider from disengaging from the slide rail in a direction away from the base.

[0022] Furthermore, it also includes a clamping bolt, and the slider has a limiting screw hole leading to the sliding groove. The clamping bolt is screwed to the limiting screw hole, and the screw end of the clamping bolt can abut against the slide rail and restrict the slider from moving along the slide rail.

[0023] By adopting the above technical solution, workers can slide the movable frame along the slide rail by loosening the tightening bolts, and then adjust the distance between the two Bailey plates. After adjusting the distance, workers can tighten the tightening bolts to abut the slide rail between the screw end of the tightening bolt and the abutment protrusion, thereby initially fixing the position of the movable frame on the slide rail.

[0024] Furthermore, a row of snap-fit ​​holes is formed on the abutment strip along the length of the slide rail on the side facing the abutment protrusion. The abutment protrusion has a snap-fit ​​protrusion on the side near the movable frame. The snap-fit ​​protrusion can be inserted into any of the snap-fit ​​holes and abut against the inner wall of the snap-fit ​​hole.

[0025] By adopting the above technical solution, when the tightening bolt is tightened to abut the slide rail between the screw end of the tightening bolt and the abutting protrusion, the snapping protrusion can be inserted into any snapping hole and abut against the inner wall of the snapping hole, so that the moving frame is less likely to move along the slide rail at this time.

[0026] Furthermore, the movable frame also includes an abutment roller, which is rotatably connected to the screw end of the tightening bolt, and the roller surface of the abutment roller abuts against the slide rail.

[0027] By adopting the above technical solution, when the base is set on an inclined surface to be constructed, the clamping bolt will rub against the slide rail when the slider slides along the slide rail. The abutting roller can reduce the friction between the clamping bolt and the slide rail and protect the clamping bolt, so that the screw end of the clamping bolt is not easily damaged due to frequent friction with the slide rail.

[0028] In summary, this application includes the following beneficial technical effects:

[0029] The system includes a base, a fixed frame, and a movable frame. The base is positioned on the surface to be constructed. The fixed frame is fixedly connected to the side of the base away from the surface, and is detachably connected to the Bailey bridge sections. The movable frame is slidably connected to the side of the base away from the surface and is detachably connected to the Bailey bridge sections. The movable frame can move the Bailey bridge sections on it closer to or further away from the Bailey bridge sections on the fixed frame along the length of the base. This allows workers to pre-fix the Bailey bridge assembly base to the surface when assembling the Bailey bridge sections into a Bailey beam on a horizontal or inclined surface, and then use a crane to... The two Bailey panels are then lifted and installed on the fixed and movable frames respectively. Next, the workers can slide the movable frame according to the model of the connecting plates used until the distance between the two Bailey panels meets the usage requirements of these connecting plates. Then, multiple connecting plates are connected to the two Bailey panels in sequence with bolts and nuts. This allows the Bailey panel assembly base to install connecting plates without the need for a crane to suspend the Bailey panels. This enables the construction site to install multiple connecting plates on the Bailey panel assembly base at the same time without being limited by the number of cranes, thus maximizing the installation efficiency of the Bailey panels.

[0036] The following is in conjunction with the appendix Figure 1-5 Further explanation:

[0037] See Figure 1 and Figure 2 In the first embodiment provided in this application, two H-shaped steel bars are horizontally spaced on the construction plane. Three Bailey panel assembly bases are parallelly spaced on the H-shaped steel bars. Each Bailey panel assembly base includes: a base 1, a fixed frame 2, and a movable frame 3. The base 1 is arranged along the width direction of the H-shaped steel bar, and the bottom of the base 1 is connected to the two H-shaped steel bars by bolts. The Bailey panel 4 includes a pair of main beams 41 and a plurality of crossbeams 42. The pair of main beams 41 are arranged in parallel and spaced apart. One end of each of the plurality of crossbeams 42 is connected to one of the two main beams 41, and the other end of each of the plurality of crossbeams 42 is connected to the other of the two main beams 41. A plurality of diagonal reinforcing ribs are also provided between the crossbeams 42 and the main beams 41. Three hanging grooves 411 are spaced apart on one of the main beams 41 away from the base 1, and three snap-fit ​​grooves are spaced apart on one of the main beams 41 closer to the base 1.

[0038] See Figure 2 and Figure 3 The fixing frame 2 includes a fixing plate 21, a fixing rod 22, a fixing hook 23, and a fixing diagonal brace 24. One side of the fixing plate 21 is connected to the base 1. One end of the fixing rod 22 is connected to the other side of the fixing plate 21. A fixing through groove is formed on the other end of the fixing rod 22 along the length of the base 1. A through hole is formed on the hook handle of the fixing hook 23 so that the fixing hook 23 can be detachably connected to the inner wall of the fixing through groove by bolts and nuts. The hook tip of the fixing hook 23 extends out of the fixing through groove from the opening on the side of the fixing through groove near the movable frame 3. A fixing block 211 is provided on the side of the fixing plate 21 away from the base 1 so that... The user can quickly connect the Bailey piece 4 to the fixed frame 2 by first fitting the snap-fit ​​groove of one Bailey piece 4 onto the fixed block 211, then inserting the hook tip of the fixed hook 23 into the hanging groove 411 of the same Bailey piece 4, and finally connecting the fixed hook 23 to the fixed rod 22. One end of the fixed diagonal brace 24 is connected to the fixed plate 21, and the other end of the fixed diagonal brace 24 is connected to the side of the fixed rod 22 away from the movable frame 3, so that the setting of the fixed diagonal brace 24 can strengthen the connection between the fixed rod 22 and the fixed plate 21.

[0039] See Figure 2 and Figure 3The movable frame 3 includes a movable plate 31, a movable rod 32, a movable hook 33, and a movable diagonal brace 34. Two slide rails 11 are provided on the base 1 along its length. Four sliders 311, each corresponding to one of the slide rails 11, are provided on one side of the movable plate 31, allowing the movable plate 31 to be slidably connected to the two slide rails 11 via the four sliders 311. One end of the movable rod 32 is connected to the side of the movable plate 31 away from the sliders 311. A movable through-slot is formed on the other end of the movable rod 32 along the length of the base 1. A through hole is formed on the hook handle of the movable hook 33, allowing the movable hook 33 to be detachably connected to the inner wall of the movable through-slot via bolts and nuts. The hook tip of the movable hook 33 approaches the fixed frame from the movable through-slot. The movable slot extends from one side opening of 2. A movable block 312 is provided on the side of the movable plate 31 away from the base 1, so that the user can first put the snap-fit ​​groove of a Bailey piece 4 onto the movable block 312, then insert the hook tip of the movable hook 33 into the hanging groove 411 of the same Bailey piece 4, and finally connect the movable hook 33 to the movable rod 32 to abut between the movable hook 33 and the movable block 312, thereby realizing the quick connection between the Bailey piece 4 and the movable frame 3. One end of the movable diagonal brace 34 is connected to the movable plate 31, and the other end of the movable diagonal brace 34 is connected to the side of the movable rod 32 away from the fixed frame 2, so that the setting of the movable diagonal brace 34 can strengthen the connection between the movable rod 32 and the movable plate 31.

[0040] The implementation principle of the first embodiment of this application is as follows:

[0041] When assembling Bailey panels 4 into Bailey beams on a horizontal or inclined construction surface, workers can pre-fix the Bailey panel assembly base to the H-beam of the construction surface using bolts and nuts. Then, a crane is used to lift two Bailey panels 4 one after another and install them on the fixed frame 2 and movable frame 3 of the three bases 1 respectively. Next, the workers can slide the movable frame 3 according to the model of the connecting piece 5 used until the distance between the two Bailey panels 4 meets the usage requirements of these connecting pieces 5. Then, multiple connecting pieces 5 are connected to the two Bailey panels 4 in sequence with bolts and nuts. This way, the Bailey panel assembly base does not need to be suspended by a crane when installing the connecting pieces 5, so that multiple connecting pieces 5 on the Bailey panel assembly base can be installed simultaneously on the construction site without being limited by the number of cranes, thus maximizing the installation efficiency of the Bailey panel 4.

[0042] Specifically, the connecting piece 5 can be a rod-shaped steel with connecting lugs at both ends for threading bolts, so that two Bailey pieces 4 can be screwed together by the connecting piece 5 to form a Bailey beam.

[0043] See Figure 4 and Figure 5The second embodiment provided in this application also includes four clamping bolts 6. A sliding groove is provided on the side of the slider 311 away from the movable frame 3. The slide rail 11 is inserted into the sliding groove. Abutment strips 111 are provided on both side walls of the slide rail 11 along its length. Two abutment protrusions 3111 are provided at the opening of the sliding groove. The two abutment protrusions 3111 correspond one-to-one with the two abutment strips 111. The side of each abutment protrusion 3111 closest to the movable frame 3 can abut against a corresponding abutment strip 111, so that when the base 1 is placed on an inclined surface to be constructed, the abutment strips 111 can abut against the abutment protrusions 3111 and restrict the slider 311 from disengaging from the slide rail 11 in a direction away from the base 1. Each slider 311 has a limiting screw hole leading to the sliding groove. The clamping bolts 6 correspond one-to-one with the limiting screw holes. Correspondingly, each clamping bolt 6 is screwed to a corresponding limiting screw hole; the movable frame 3 also includes four abutting rollers 35, each abutting roller 35 corresponding to a clamping bolt 6, each abutting roller 35 being rotatably connected to the screw end of a corresponding clamping bolt 6, and the roller surface of each abutting roller 35 being able to abut against the slide rail 11; each abutting protrusion 3111 is provided with a locking protrusion 3112 on the side near the movable frame 3, the locking protrusion 3112 can be a semi-cylindrical protrusion, and the cross section of the locking protrusion 3112 in the length direction of the slide rail 11 is semi-circular, and a row of locking holes adapted to the locking protrusion 3112 are opened on each abutting strip 111 along the length direction of the slide rail 11 facing the abutting protrusion 3111, so that the locking protrusion 3112 can be inserted into any locking hole and abut against the inner wall of the locking hole.

[0044] The implementation principle of the second embodiment of this application is as follows:

[0045] Workers can slide the movable frame 3 along the slide rail 11 by loosening the clamping bolt 6, and then adjust the distance between the two Bailey pieces 4. When the base 1 is set on the inclined construction surface, the clamping bolt 6 will rub against the slide rail 11 when the slider 311 slides along the slide rail 11. The abutment roller 35 can reduce the friction between the clamping bolt 6 and the slide rail 11 and protect the clamping bolt 6 so that the screw end of the clamping bolt 6 is not easily damaged due to frequent friction with the slide rail 11. After adjusting the distance, workers can tighten the clamping bolt 6 to abut the slide rail 11 between the screw end of the clamping bolt 6 and the abutment protrusion 3111. At this time, the snap-fit ​​protrusion 3112 can be inserted into any snap-fit ​​hole and abut against the inner wall of the snap-fit ​​hole, so as to initially fix the position of the movable frame 3 on the slide rail 11, which makes it convenient for users to quickly install the connecting piece 5 between the two Bailey pieces 4.

[0046] It should be noted that the above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
