Description

Technical Field

[0001] The invention belongs to the technical field of continuous beam construction, and more specifically, relates to a pre-compression bracket for a zero-block of a continuous beam. Background Art

[0002] In modern bridge engineering construction, continuous beam structures are widely used. Block 0 of the continuous beam is located on the top of the pier and is the key starting point for the entire continuous beam construction. Its construction quality and safety directly affect the construction of subsequent beam sections and the structural performance of the entire bridge. During the construction of the block 0 of the continuous beam, temporary supports are usually required to support the formwork and concrete loads during the pouring process. By pre-stressing the support, the actual load or overload applied during the construction of the block 0 can be simulated, thereby comprehensively testing the strength, stiffness and stability of the support, discovering potential safety hazards in the support system in advance and making corrections.

[0003] Among them, sandbags are commonly used preloading materials because their weight is easy to control and they are convenient to carry and stack. However, when using sandbags for preloading, facing the large preloading weight requirement of the zero block of the continuous beam, a large number of sandbags need to be piled up to achieve the required load. This results in a large number of hoisting times and a small single hoisting volume when hoisting the sandbags to the preloading bracket, making the entire hoisting process time-consuming, extending the preloading construction period, and increasing labor costs and equipment usage costs. Summary of the invention

[0004] The object of the present invention is to provide a pre-stressing bracket for the zero block of a continuous beam, so as to facilitate the transfer of sandbags to the bracket of the zero block of the continuous beam for pre-stressing.

[0005] To achieve the above object, the technical solution adopted by the present invention is: to provide a continuous beam zero block preloading bracket, comprising a plurality of frames stacked up and down; Each of the frames has an internal space for accommodating a plurality of sandbags; A lifting piece is fixedly provided on the top of the frame, and the lifting piece is used to be connected with a hook; A connecting piece is fixedly provided at the bottom of the frame, the connecting piece corresponds to the upper and lower positions of the lifting piece, and the connecting piece is used to lock and unlock the lifting piece; A transmission member is connected between the lifting member and the connecting member; Among them, when two adjacent frames are stacked up and down, the lifting member of the lower frame is plugged into and locked with the connecting member of the upper frame; when the frame is lifted, the hook is connected to the lifting member, and the connecting member is driven to move through the transmission member to unlock the connecting member.

[0006] In a possible implementation, the connecting member includes: A connecting part, fixedly arranged at the bottom of the frame, and plugged with the lifting member up and down; A locking portion, which is horizontally slidably disposed on the connecting portion and is suitable for being horizontally plugged into the lifting member; Wherein, the locking portion is connected to the transmission member, and when the transmission member is actuated, the locking portion moves horizontally.

[0007] In a possible implementation, the connection portion is provided with a slot suitable for the lifting member to be inserted in the up-down direction.

[0008] In a possible implementation, the transmission member includes: A triggering part is vertically slidably arranged on the lifting member; A first rack, vertically fixed on the triggering portion; A transmission gear, horizontally rotatably disposed on the frame and meshing with the first rack; A second rack, horizontally fixed on the locking portion and meshing with the transmission gear; Wherein, when the lifting hook lifts the lifting member, the hook extends under the trigger part and abuts against the trigger part, so that the hook pushes the trigger part to move upward; When the locking portion is plugged into the lifting member, the locking portion extends above the trigger portion and abuts against the trigger portion, so that the locking portion restricts the trigger portion from moving upward.

[0009] In a possible implementation, the transmission member further includes: The first spring is fixedly arranged between the first rack and the frame, and is used for pushing the first rack to move downward.

[0010] In a possible implementation, the frame includes: Two frame parts; A plug-in portion, horizontally fixedly disposed on one of the frame portions; A socket part, horizontally fixedly arranged on the other frame part, and horizontally plugged with the socket part; A positioning assembly, arranged on the socket part, for fixing the plug part; Wherein, when the depth of the plug-in portion inserted into the socket portion changes, the size of the internal space changes.

[0011] In a possible implementation, the positioning component includes: A positioning member, which is arranged on the socket portion and has elastic freedom to move toward the socket portion, and the moving direction of the positioning member is perpendicular to the plugging direction of the plug-in portion; Wherein, the plug-in portion is provided with a plurality of plug-in holes evenly distributed along the plug-in direction, and the positioning member is suitable for being plugged into any of the plug-in holes.

[0012] In a possible implementation, the positioning member includes: A plug rod, slidably connected to the socket portion; A second spring, both ends of which are respectively fixed to the insertion rod and the socket portion, and is sleeved on the insertion rod; Wherein, when the second spring is in the original length state, the insertion rod can be inserted into any of the insertion holes.

[0013] In a possible implementation, the frame further includes: A connecting sleeve, horizontally fixedly disposed on one of the frame parts; A connecting rod, horizontally fixedly disposed on the other frame body part and plugged into the connecting sleeve; Wherein, the plug-in direction of the connecting rod and the connecting sleeve is the same as the plug-in direction of the plug-in part and the socket part.

[0014] In one possible implementation, a guide plate is fixedly provided on the top of the frame, and the guide plate has a guide slope. When two adjacent frames are stacked up and down, the upper frame rests on the guide slope and moves along the guide slope, so that the guide slope guides the upper frame to align with the lower frame.

[0015] Compared with the prior art, the present invention provides a prestressing bracket for the zero block of a continuous beam. The beneficial effect is that during the prestressing operation, multiple sandbags can be placed in a frame body, which significantly increases the amount of sandbags lifted in a single time compared to the traditional single sandbag lifting, greatly reduces the number of lifting times, and speeds up the construction progress of the prestressing of the zero block of the continuous beam. In the prestressing of the zero block of a large continuous beam, multiple frames can be stacked up and down to meet the load required for prestressing. When the frames are stacked up and down, the two adjacent frames can be locked together by the lifting parts and the connecting parts, so that the multiple frames are closely connected and will not easily fall or slip. When the frame is lifted, the hook drives the connecting part to unlock through the transmission part, so that the two adjacent frames are separated, and there is no need for workers to climb onto the frame to unlock, which greatly reduces safety hazards.

DETAILED DESCRIPTION

[0019] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0020] See also Figure 1 Now, a preloading bracket for the zero block of a continuous beam provided by the present invention is described. A preloading bracket for the zero block of a continuous beam comprises a plurality of frames 1 stacked up and down. Each frame 1 has an internal space for accommodating a plurality of sandbags at the same time, thereby greatly increasing the preloading weight of a single hoisting, reducing the number of hoisting times, significantly shortening the hoisting time, and accelerating the process of preloading construction.

[0021] See also Figure 1, a lifting member 2 is fixedly provided on the top of the frame 1, and the lifting member 2 is used to be connected to the hook. A connecting member 3 is fixedly provided on the bottom of the frame 1, and the connecting member 3 corresponds to the upper and lower positions of the lifting member 2, and the connecting member 3 is used to lock and unlock the lifting member 2. A transmission member 4 is connected between the lifting member 2 and the connecting member 3. When two adjacent frames 1 are stacked up and down, the lifting member 2 of the lower frame 1 is plugged into and locked with the connecting member 3 of the upper frame 1. When the frame 1 is lifted, the hook is connected to the lifting member 2, and the connecting member 3 is driven to move through the transmission member 4 to unlock the connecting member 3.

[0022] In the preloading of the zero block of a large continuous beam, multiple frames 1 can be stacked up and down to meet the load required for preloading. When the frames 1 are stacked up and down, the two adjacent frames 1 can be locked together through the lifting parts 2 and the connecting parts 3, so that the multiple frames 1 are tightly connected and will not easily fall or slip. When the frame 1 located above is lifted, the hook drives the connecting part 3 through the transmission part 4 to unlock the connecting part 3 and the lifting part 2, so that the two adjacent frames 1 can be separated, without the need for workers to climb onto the frames 1 to perform the unlocking operation, which greatly reduces safety hazards.

[0023] In some embodiments, see Figure 2 The connecting member 3 includes a connecting portion 31 and a locking portion 32. The connecting portion 31 is fixedly arranged at the bottom of the frame 1 and is plugged into the lifting member 2 up and down. The locking portion 32 is horizontally slidably arranged on the connecting portion 31 and is suitable for being horizontally plugged into the lifting member 2. The locking portion 32 is connected to the transmission member 4, and when the transmission member 4 is actuated, the locking portion 32 moves horizontally.

[0024] Specifically, the upper and lower plugging of the connection part 31 and the lifting member 2 provides a basic connection limit for the stacking of the frame 1, so that when multiple frames 1 are stacked up and down, they are not easily misaligned with each other, thereby improving the stability of the connection between the upper and lower adjacent frames 1. When the hook is connected to the lifting member 2, the connection member 3 is in an unlocked state. At this time, stacking the frame 1 on top of another frame 1 can make the lifting member 2 on the lower frame 1 vertically plugged into the connection part 31 on the upper frame 1. Then, disengaging the hook from the lifting member 2 on the upper frame 1 will cause the transmission member 4 to drive the locking part 32 to move horizontally and plug into the lifting member 2 on the lower frame 1, thereby achieving a fixed connection between the upper and lower adjacent frames 1.

[0025] In some embodiments, see Figure 2 The connecting portion 31 is provided with a slot 311 suitable for the lifting member 2 to be inserted in the up-down direction. The slot 311 on the connecting portion 31 provides a plugging position for the lifting member 2, ensuring the coaxiality and verticality when the upper and lower frames 1 are connected.

[0026] In some embodiments, see Figure 2 The transmission member 4 includes a triggering portion 41, a first rack 42, a transmission gear 43 and a second rack 44. The triggering portion 41 is vertically slidably arranged on the lifting member 2. The first rack 42 is vertically fixed on the triggering portion 41. The transmission gear 43 is horizontally rotatably arranged on the frame 1 and meshes with the first rack 42. The second rack 44 is horizontally fixed on the locking portion 32 and meshes with the transmission gear 43.

[0027] When the hook lifts the lifting member 2, the hook extends below the trigger portion 41 and abuts against the trigger portion 41, so that the hook pushes the trigger portion 41 to move upward. When the locking portion 32 is plugged into the lifting member 2, the locking portion 32 extends above the trigger portion 41 and abuts against the trigger portion 41, so that the locking portion 32 restricts the trigger portion 41 from moving upward.

[0028] Specifically, the trigger part 41 is arranged in the space enclosed by the lifting member 2 and the frame 1. When the trigger part 41 is in a natural state, the trigger part 41 is located at the middle height of the lifting member 2. When the frame 1 needs to be lifted, the hook is extended into the lifting member 2 so that the hook is below the trigger part 41. The hook is lifted upward to abut against the lower surface of the trigger part 41 and push the trigger part 41 to move upward. When the trigger part 41 moves upward, it can drive the first rack 42 to move vertically upward, the first rack 42 drives the transmission gear 43 to rotate, the transmission gear 43 drives the second rack 44 to move horizontally, and the second rack 44 drives the locking part 32 to move horizontally and be pulled out of the lifting member 2, thereby realizing the separation between the two adjacent frames 1 above and below.

[0029] In addition, when three racks 1 are stacked up and down, the locking portion 32 on the top rack 1 can be inserted into the lifting piece 2 on the middle rack 1 and abut against the upper surface of the trigger portion 41 on the middle rack 1, ensuring that the trigger portion 41 on the middle rack 1 will not move upward, thereby ensuring the stability of the connection between the middle rack 1 and the bottom rack 1. When multiple racks 1 are stacked up and down, the racks 1 can only be separated and lifted layer by layer from top to bottom, thereby ensuring the overall stability of the multiple racks 1 when stacked.

[0030] In some embodiments, see Figure 2 The transmission member 4 further includes a first spring 45 fixedly disposed between the first rack 42 and the frame body 1 , and the first spring 45 is used for pushing the first rack 42 to move downward.

[0031] Specifically, when the trigger part 41 moves upward, the first spring 45 is compressed to store energy. When the hook and the lifting member 2 are separated, the first spring 45 releases energy to push the trigger part 41 to move downward and reset. The trigger part 41 is reset by the first spring 45, which reduces the problem of poor movement caused by jamming or friction between components and improves reliability during use.

[0032] In some embodiments, see Figure 1 The frame 1 includes two frame parts 11, a plug-in part 12, a socket part 13 and a positioning assembly. The plug-in part 12 is horizontally fixed on one frame part 11. The socket part 13 is horizontally fixed on the other frame part 11 and is horizontally plugged with the socket part 13. The positioning assembly is arranged on the socket part 13 to fix the plug-in part 12. When the depth of the plug-in part 12 inserted in the socket part 13 changes, the size of the internal space changes.

[0033] The size of the internal space of the frame 1 can be adjusted by changing the depth of the plug-in portion 12 in the socket portion 13, thereby adjusting the overall size of the frame 1 and the amount of sandbags contained in the frame 1. In the preloading construction of the continuous beam block 0, the size of the frame 1 and the internal space of the frame 1 can be flexibly adjusted according to different preloading weight requirements and sandbag sizes. For continuous beam projects with a smaller preloading weight, the internal space can be reduced to reduce the amount of sandbags used; for large preloading projects, the internal space can be increased, thereby improving the versatility and adaptability of the frame 1 and reducing the cost of replacing frames 1 of different specifications due to changes in preloading requirements.

[0034] Specifically, when adjusting, the staff only needs to insert the plug-in part 12 into the socket part 13 to an appropriate depth according to the actual preloading requirements, and fix it through a positioning component. No special processing equipment or complicated assembly process is required. It is convenient and fast, improves construction efficiency, and can better meet the changing working conditions in the preloading construction of the continuous beam zero block.

[0035] In some embodiments, see Figure 1 and Figure 3 The positioning assembly includes a positioning member 14 disposed on the socket 13, the positioning member 14 has elastic freedom to move toward the socket 13, and the moving direction of the positioning member 14 is perpendicular to the plugging direction of the plug-in portion 12. The plug-in portion 12 is evenly distributed with a plurality of plug holes 121 along the plugging direction, and the positioning member 14 is suitable for being plugged into any plug hole 121.

[0036] The positioning member 14 has elastic freedom on the socket part 13 and can cooperate with the socket 121 on the plug part 12, so as to realize the positioning of the plug part 12 and the socket part 13 at different splicing depths. When adjusting the internal space of the frame 1, the positioning member 14 can be accurately inserted into the socket 121 at the corresponding position, ensuring that the plug part 12 and the socket part 13 are tightly and stably connected, avoiding deformation of the frame 1 or reduction of the bearing capacity due to loose connection, ensuring the structural integrity and stability of the frame 1, and improving the reliability and safety of the frame 1 when in use.

[0037] In some embodiments, see Figure 3 The positioning member 14 includes an insertion rod 141 and a second spring 142. The insertion rod 141 is slidably connected to the socket 13. The two ends of the second spring 142 are respectively fixed to the insertion rod 141 and the socket 13, and are sleeved on the insertion rod 141. When the second spring 142 is in the original length state, the insertion rod 141 can be inserted into any socket 121.

[0038] When adjusting the size of the frame 1, the plug rod 141 is pulled out from the insertion hole 121, so that the plug part 12 and the socket part 13 can move relative to each other. When the frame 1 is adjusted to the required size, the plug rod 141 is released, so that the plug rod 141 is inserted into the insertion hole 121 at the corresponding position under the drive of the second spring 142, so that the connection between the plug part 12 and the socket part 13 can be achieved.

[0039] In some embodiments, see Figure 1 The frame 1 further includes a connecting sleeve 15 and a connecting rod 16. The connecting sleeve 15 is horizontally fixedly arranged on one frame body part 11. The connecting rod 16 is horizontally fixedly arranged on the other frame body part 11 and plugged with the connecting sleeve 15. The plugging direction of the connecting rod 16 and the connecting sleeve 15 is the same as the plugging direction of the plug-in part 12 and the socket part 13.

[0040] Specifically, the plug-in portion 12 and the socket portion 13 are both arranged on the bottom surface of the frame portion 11 , and the connecting sleeve 15 and the connecting rod 16 are both arranged on the side surface of the frame portion 11 .

[0041] When the insertion depth of the plug-in portion 12 and the socket portion 13 is adjusted, the insertion depth between the connecting sleeve 15 and the connecting rod 16 is also changed simultaneously. The connection between the connecting sleeve 15 and the connecting rod 16 serves to reinforce the two frame parts 11, making the frame 1 more stable as a whole and less likely to deform when carrying sandbags.

[0042] In some embodiments, see Figure 1A guide plate 5 is fixedly provided on the top of the frame 1, and the guide plate 5 has a guide slope 51. When two adjacent frames 1 are stacked up and down, the upper frame 1 rests on the guide slope 51 and moves along the guide slope 51, so that the guide slope 51 guides the upper frame 1 to be aligned with the lower frame 1.

[0043] The guide plate 5 on the top of the frame 1 plays a guiding and aligning role when the adjacent frames 1 are stacked up and down. When the upper frame 1 is placed on the lower frame 1, the upper frame 1 can abut against the guide slope 51 and move along the guide slope 51, thereby automatically correcting the position deviation of the frame 1. The guide slope 51 can make the upper frame 1 slide smoothly into the correct position and align with the lower frame 1, thereby improving the success rate and efficiency of stacking the frames 1 and reducing construction delays caused by alignment problems.

[0044] In summary, compared with the prior art, the present invention provides a continuous beam zero block prestressing bracket. During the prestressing operation, multiple sandbags can be concentrated in the frame 1. Compared with the traditional single sandbag lifting, the amount of sandbags lifted in a single time is significantly increased, the number of lifting times is greatly reduced, and the construction progress of the continuous beam zero block prestressing is accelerated. In the prestressing of large-scale continuous beam zero blocks, multiple frames 1 can be stacked up and down to meet the load required for prestressing. When the frames 1 are stacked up and down, the two adjacent frames 1 can be locked together through the lifting parts 2 and the connecting parts 3, so that the multiple frames 1 are closely connected and will not easily fall or slip. When the frame 1 is lifted, the hook drives the connecting part 3 to unlock through the transmission part 4, so that the two adjacent frames 1 are separated, and there is no need for workers to climb onto the frame 1 to unlock, which greatly reduces safety hazards.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
