Description

Technical Field

[0001] This invention relates to the field of building construction, specifically to an external hanging basket for wet joint construction of highway bridges and its usage method. Background Technology

[0002] In modern bridge construction, precast concrete structures are widely used due to their efficiency and predictability. However, after assembly, gaps often remain between the various parts of the bridge. These gaps have a significant impact on the overall stability and safety of the bridge. Therefore, artificial jointing of these gaps is a crucial step in ensuring the structural integrity of the bridge.

[0003] Joint construction typically takes place at the bottom of the bridge, a location whose unique characteristics make the work exceptionally difficult. Due to the confined space, workers must perform precise operations within extremely limited areas, which is a significant test of their skills and patience. To provide a relatively stable and safe working environment, suspended platforms are usually used. These platforms can accommodate one or more workers and are lifted to the bottom of the bridge by a crane, allowing them to work in a relatively comfortable environment.

[0004] However, existing suspended platform designs also have some problems. While detachable suspended platforms are convenient for transportation and storage, they require handling a large number of bolts during installation and dismantling. This not only increases the complexity of the operation but also prolongs the overall construction time. Furthermore, standard suspended platform dismantling procedures require unmanned operation, but in actual construction sites, sometimes for convenience, workers perform dismantling work directly inside the suspended platform, which undoubtedly increases safety risks. Summary of the Invention

[0005] In view of the above situation and to overcome the defects of the prior art, the present invention provides an external hanging basket for the construction of wet joints of highway bridges and a method for using it, so as to solve the problems involved in the background art.

[0016] Furthermore, a support frame is provided at the bottom of the base plate, and the support frame is fixedly connected to the side plate;

[0017] The support frame includes a support plate, and a number of threaded rods are linearly arrayed at the bottom of the support plate. The support plate is provided with a number of second through holes, and fastening bolts are installed in the second through holes. The fastening bolts pass through the second through holes and are threaded into the threaded holes of the base plate. The bottom of the side plate is provided with a number of first through holes, and the ends of the threaded rods pass through the first through holes and are fixedly connected to the side plate by tightening nuts.

[0018] Furthermore, the tightening nut includes a left-hand tightening nut and a right-hand tightening nut. When the support plate is fixedly connected to the bottom of the base plate, the end of the threaded rod passes through the first through hole and is locked and fixed by the left-hand tightening nut and the right-hand tightening nut. The left-hand tightening nut and the right-hand tightening nut are respectively located on both sides of the side plate.

[0019] Furthermore, the top of the mounting cavity is a top plate, and a pressure sensor is provided on the lower end face of the top plate;

[0020] The bottom of the side slide groove is provided with a mounting hole, and a distance sensor is provided in the mounting hole. The distance sensor is used to detect the position of the guide block.

[0022] Furthermore, the connecting component includes a first plate and a second plate, the first plate being fixedly connected to the second plate, the first plate and the second plate forming a 90° angle, the end of the first plate being provided with a first locking block, the end of the second plate being provided with a second locking block, the side plate and the connecting plate being provided with vertical slots that cooperate with the first locking block and the second locking block, the first locking block and the second locking block being inserted into the vertical slots.

[0023] The method and steps for using external hanging baskets in the construction of wet joints of highway bridges include:

[0024] 1. Install side panels and support brackets:

[0025] The side plate is slidably fitted into the sliding groove of the base plate via the plug-in slider. The support plate of the support bracket is placed at the bottom of the base plate, and the threaded rod is fixed to the side plate by tightening the nut to ensure that the support plate is firmly connected to the bottom of the base plate.

[0026] II. Connecting side panels and connecting plates:

[0027] Connecting members are used to connect adjacent side plates and connecting plates together. The first plate of the connecting member is fixedly connected to the connecting plate by bolts, and the second plate is fixedly connected to the side plate by bolts. Alternatively, the connecting member can be inserted into the vertical slots on the side plate and the connecting plate to achieve relative movement between the side plate and the connecting plate.

[0028] III. Activate the locking mechanism:

[0029] Insert the plug-in plate into the slot on the base plate, and rotate the threaded column to insert the rack into the horizontal insertion hole of the plug-in plate to limit the relative movement between the plug-in plate and the base plate.

[0030] IV. Using external baskets:

[0031] Install slings or hooks on the lifting rings and hoist the entire external basket to the construction location of the bridge wet joint, so that construction workers can enter the external basket to carry out construction operations.

[0032] V. Disassembling the external hanging basket:

[0033] When it is necessary to remove the external basket, use a tool to insert it through the rotating hole and into the top of the rotating threaded column. Rotate the rotating threaded column to disengage the rack from the horizontal insertion hole. At the same time, the anti-slip plate will rest against the ground. Then the connecting plate, side plate and support frame can be removed.

[0034] Compared with the prior art, the beneficial effects of the present invention are:

[0035] The sliding fit between the base plate and side plates, along with the fixed connection of the support frame, ensures stable load-bearing and balance of the suspended platform during construction. A unique locking mechanism, through the coordinated action of components such as racks, gears, rotating shafts, and synchronous belts, achieves reliable connection and rapid unlocking between the plug-in plate and the base plate. Simultaneously, this mechanism integrates pressure and distance sensors to ensure safe use of the suspended platform within prohibited disassembly areas. The design of the connecting components further strengthens the bond between the side plates and the connecting plate, improving the overall structural stability. Furthermore, detailed designs such as the lifting rings and rotating doors fully consider convenience and safety during construction. This application not only boasts a robust structure and simple operation but also effectively improves the efficiency and safety of wet joint construction for highway bridges.

Detailed Implementation

[0047] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0048] Example 1:

[0049] Depend on Figure 1-7 As shown, an external hanging basket for the construction of wet joints of highway bridges includes a base plate 1, with side plates 2 connected to both sides of the base plate. Adjacent side plates 2 are connected together by a connecting plate 3. A support frame 5 is provided at the bottom of the base plate 1, and the support frame 5 is fixedly connected to the side plates 2. A lower plate 32 is connected to the connecting plate 3, and a plug-in plate 33 is connected to the lower plate 32. A slot 77 is provided at the bottom of the base plate 1, and a locking mechanism is installed inside the base plate 1. When the plug-in plate 33 is inserted into the slot 77, the locking mechanism can restrict the relative movement between the plug-in plate 33 and the base plate 1.

[0050] The locking mechanism includes a rack 713, a gear 711, a rotating shaft 710, a synchronous belt 712, a rotating threaded post 76, and a sliding sleeve 75. A horizontal groove 78 is provided in the base plate 1, within which the rack 713 is slidably fitted. A horizontal insertion hole is provided at the end of the insertion plate 33. When the insertion plate 33 is inserted into the slot 77, the rack 713 can be inserted into the horizontal insertion hole to restrict the relative movement between the insertion plate 33 and the base plate 1. A mounting cavity S1 is formed within the base plate 1, and a rotating shaft 710 is rotatably connected within the mounting cavity S1. A gear 711 is mounted on the rotating shaft 710. 11. The gear 711 meshes with the rack 713. A driven synchronous pulley is provided on the rotating shaft 710. Correspondingly, a through hole 71 is provided at the bottom right side of the mounting cavity S1. A sliding sleeve 75 is slidably fitted within the through hole 71. The sliding sleeve 75 has internal threads. A rotating threaded column 76 is rotatably connected within the mounting cavity S1. The rotating threaded column engages with the sliding sleeve 75. A driving synchronous pulley is provided on the rotating threaded column 76. The driving synchronous pulley and the driven synchronous pulley are driven by a synchronous belt. A rotating hole 101 is formed at the top of the rotating threaded column. Side sliding grooves 72 are provided on both sides of the through hole 71. Guide blocks 73 are slidably fitted within the side sliding grooves and are fixedly connected to the sliding sleeve 75. An anti-slip pad 74 is provided at the bottom of the sliding sleeve 75.

[0051] When disassembling the suspended platform, a tool is inserted through the rotating hole 101 and then into the top of the rotating threaded column 76, causing the rotating threaded column 76 to rotate. Since the rotating threaded column 76 engages with the sliding sleeve 75, and the sliding sleeve 75 can move up and down along the through hole 71, the sliding sleeve 75 moves vertically downward under the drive of the rotating threaded column 76, thereby causing the anti-slip pad 74 to gradually approach the ground. At the same time, since the rotating threaded column is connected to the rotating shaft 710 via the synchronous belt 712, and the gear 711 on the rotating shaft 710 can drive the rack 713, the gear 711 drives the rack 713 to move away from the horizontal insertion hole until it is disengaged from the horizontal insertion hole. With the support of the sliding sleeve 75, the connecting plate 3, side plate 2, and support frame of the suspended platform can be disassembled at this time.

[0052] A connecting member 4 is provided at the junction of the side plate 2 and the connecting plate 3. The connecting member 4 includes a first plate 41 and a second plate 42. The first plate 41 is fixedly connected to the second plate 42, and the first plate 41 and the second plate 42 form a 90° angle. The first plate 41 and the second plate 42 can also be formed by bending a single plate at a 90° angle. The first plate 41 is fixedly connected to the connecting plate 3 by bolts, and the second plate 42 is fixedly connected to the side plate 2 by bolts.

[0053] A rotating door 23 is provided on the side plate 2. The rotating door 23 is locked to the side plate 2 by a pin to prevent people from falling out of the basket during operation. Lifting rings 6 are installed on the side plate 2 and the connecting plate 3. Sliding grooves 22 are provided on both sides of the bottom plate 1. Correspondingly, the bottom of the side plate 2 is provided with a sliding block 21 that mates with the sliding groove 22.

[0054] The support frame 5 includes a support plate 51. The bottom of the support plate 51 has a plurality of threaded rods 52 arranged linearly. The support plate 51 has a plurality of second through holes 511, in which fastening bolts are installed. The fastening bolts pass through the second through holes 511 and are threaded into the threaded holes of the base plate 1. The bottom of the side plate 2 has a plurality of first through holes. The ends of the threaded rods 52 pass through the first through holes and are fixedly connected to the side plate by tightening nuts 53. The tightening nuts 53 include left-hand tightening nuts 531 and right-hand tightening nuts 532. When the support plate 51 is fixedly connected to the bottom of the base plate 1, the ends of the threaded rods 52 pass through the first through holes and are locked in place by the left-hand tightening nuts 531 and right-hand tightening nuts 532. The left-hand tightening nuts 531 and right-hand tightening nuts 532 are located on opposite sides of the side plate 2.

[0055] The steps for using the external basket are as follows:

[0056] 1. Install the side panel and support bracket: Slide the side panel into the sliding groove of the base plate using the plug-in slider. Place the support plate of the support bracket at the bottom of the base plate and fix the threaded rod to the side panel by tightening the nut, ensuring that the support plate is firmly connected to the bottom of the base plate.

[0057] 2. Connecting side plates and connecting plates: Connecting components are used to connect adjacent side plates and connecting plates together. The first plate of the connecting component is fixedly connected to the connecting plate with bolts, and the second plate is fixedly connected to the side plate with bolts, realizing relative movement between the side plates and the connecting plate.

[0058] 3. Activate the locking mechanism: Insert the connector plate into the slot on the base plate. Then, by rotating the threaded column, insert the rack into the horizontal socket of the connector plate to restrict the relative movement between the connector plate and the base plate.

[0059] 4. Use of external hanging basket: Install slings or hooks on the lifting rings and hoist the entire external hanging basket to the construction location of the bridge wet joint. Construction personnel can then enter the external hanging basket to carry out construction operations.

[0060] 5. Removing the external basket: When it is necessary to remove the external basket, first use a tool to insert it through the rotating hole and into the top of the rotating threaded column. Rotate the threaded column to disengage the rack from the horizontal insertion hole. At the same time, the anti-slip plate will rest against the ground. Then, the connecting plate, side plate, and support frame can be removed.

[0061] It is important to note that before using the external hanging basket, ensure all components are correctly installed and securely connected. During construction, workers should stand inside the external hanging basket and pay attention to safe operations to avoid accidents. Disassembly work inside the hanging basket is prohibited to prevent accidents. When disassembly of the external hanging basket is necessary, follow the correct procedures and ensure appropriate support and protective measures are in place during disassembly. The above usage steps are for reference only and may not include all details. In actual use, please follow relevant safety regulations and operating guidelines, and adjust and operate according to specific circumstances.

[0062] Example 2:

[0063] The similarities between this embodiment and Embodiment 1 will not be repeated here. The differences are as follows:

[0064] Depend on Figure 1-7 As shown, the top of the mounting cavity S1 is a top plate 714. A pressure sensor 715 is installed between the top plate 714 and the mounting cavity S1. The bottom of the side sliding groove 72 has a mounting hole 716, and a distance sensor 717 is installed in the mounting hole 716. Because this device is prohibited from being disassembled inside the suspended platform, if a worker is disassembling it inside the suspended platform, and is at the top of the top plate 714, forcibly using a tool to rotate the threaded column 76 will cause the rack 713 to disengage from the horizontal insertion hole, and the connecting plate 3 will no longer be connected to the bottom plate 1, posing a safety hazard. However, the installation of the pressure sensor 715 and the distance sensor 717 will prevent this from happening. When the pressure sensor 715 detects someone on the top plate 714, it can transmit a signal to the control board. When the distance sensor 717 detects the movement of the guide block 73, the control board determines that a worker is disassembling the suspended platform, and the control board controls the alarm to sound and the warning light to flash.

[0065] Example 3:

[0066] The similarities between this embodiment and Embodiment 1 will not be repeated here. The differences are as follows:

[0067] like Figure 8-9 As shown, the connecting member 4 includes a first plate 41 and a second plate 42. The first plate 41 is fixedly connected to the second plate 42. The first plate 41 and the second plate 42 form a 90° angle. The end of the first plate 41 is provided with a first locking block 411, and the end of the second plate 42 is provided with a second locking block 412. The side plate 2 and the connecting plate 3 are provided with vertical slots that cooperate with the connecting member 4. When the connecting member 4 is inserted into the vertical slot, the relative movement between the connecting plate 3 and the side plate 2 can be realized.

[0068] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
