Description

Technical Field

[0001] The invention relates to the field of engineering construction, and in particular to a quick-detachable support beam that can be used for a steel-concrete combined hanging box. Background Art

[0002] A high pile cap is a cap whose bottom surface is above the foundation surface, that is, the top elevation of the pile in the pile foundation is above the ground or water surface. Since the bottom of the high pile cap is higher than the ground (or water surface), its force and stability are better than those of the low pile cap. Its force mode is that the pile body is first loaded and then transferred to the cap and the soil. Therefore, the pile body is subjected to greater force, and the pile body is compressed greatly after being loaded, and the pile foundation settlement is also large. High pile caps are mostly used in bridge projects or port and wharf projects. The main function of the cap is to transfer the upper structure load to the foundation through the pile foundation to ensure the safety and stability of the structure.

[0003] Currently, when using high-pile caps to build the main piers of bridges, steel casings are first installed at the predetermined construction site, and the concrete bottom plate and wall panels of the hanging box are prefabricated in the factory. The concrete bottom plate and wall panels are transported to the predetermined construction site and assembled into a hanging box. Support beams are inserted into the steel casings, and then the hanging box is put on the steel casings as a whole and supported by the support beams. Workers then pour concrete into the hanging box to form a cap.

[0004] With regard to the above-mentioned related technologies, after the hanging box is raised in the subsequent process, the support beam needs to be pulled out and used in reverse; however, the hanging box is too large and it is difficult for workers to cross the hanging box and enter the water to extract the support beam. Summary of the invention

[0005] In order to facilitate workers to take out and reuse the support beam inserted in the steel casing, the present application provides a quick-detachable support beam that can be used for a steel-concrete composite hanging box.

[0006] The present application provides a quick-detachable support beam that can be used for a steel-concrete composite hanging box, which adopts the following technical solution:

[0007] A quick-detachable support beam that can be used for a steel-concrete combined hanging box, comprising a support beam body, wherein the support beam body is inserted into a steel casing used in conjunction with the support beam, the support beam body comprises two hinged sections hinged to each other, the steel casing is provided with an installation groove for the hinged sections to slide; a locking assembly is installed on the support beam body for locking the two hinged sections after rotation.

[0008] By adopting the above technical solution, when the hoisting box is lifted, the hoisting box no longer abuts against the supporting beam. At this time, the worker pulls the supporting beam to drive the two hinged sections to rotate relative to each other, and the supporting beam can be lifted from the steel casing and quickly taken out from under the water surface. Through this disassembly method, firstly, it can reduce the process of workers stepping over the hoisting box to take the supporting beam body out of the water, thereby increasing the safety factor of workers' construction, and secondly, the disassembly structure is simple, which is convenient for workers to operate.

[0009] Preferably, the locking assembly includes a locking block and a latch, the locking block is fixedly mounted on one of the hinged sections, a locking groove is provided on the other hinged section, and the locking block is mounted on the other hinged section through the locking groove; the latch is simultaneously penetrated through the fixed block and the hinged section.

[0010] By adopting the above technical solution, when the two hinged sections are rotated and spliced ​​to form the support beam body, the locking block is installed on the other hinged section. At this time, the pin is inserted into the locking block and the hinged section at the same time to complete the locking, and the workers can insert the support beam body into the steel casing; when dismantling the support beam body, it is only necessary to pull out the pin to release the lock of the support beam body by the pin, and then lift the support beam body so that the two hinged sections rotate under their own gravity, which is convenient for workers to lift it from the steel casing.

[0011] Preferably, a reinforcing component is provided on the support beam body for reinforcing the structural strength when the two hinged sections are placed on the steel casing.

[0012] By adopting the above technical solution, because the support beam body is divided into two hinged sections hinged to each other, the overall structural strength is reduced. In order to reduce the bending deformation of the support beam body by the heavy base plate, a reinforcement component is provided on the support beam body. This can effectively improve the structural strength of the support beam body and thereby improve the supporting strength for the base plate.

[0013] Preferably, the upper side of the support beam body is used to abut against the concrete base plate; the reinforcement assembly includes a pair of reinforcement rods and a pair of driving blocks, each of the hinge sections is provided with a sliding groove extending along its own length direction, and the two reinforcement rods are respectively slidably installed on the two hinge sections on the same support beam body through the sliding groove; each hinge section is connected with a driving groove at the groove bottom of the sliding groove, and the driving block is slidably installed on the hinge section through the driving groove, the driving block protrudes from the hinge section on the upper side and is provided with a guide surface, and the concrete base plate abuts against the driving block; the driving block abuts against the reinforcement rod; the two hinge sections on the same support beam body are provided with a connecting groove for inserting the reinforcement rod after sliding on the side close to each other; a reset member for driving the reinforcement rod to return to the corresponding hinge section is provided on the support beam body, and when the concrete base plate is raised, the reset member drives the reinforcement rod to return to its original position.

[0014] By adopting the above technical scheme, after the base plate unit is installed on the steel casing, the lower side of the base plate unit abuts against the two driving blocks on the support beam body, and the two driving blocks are pushed to move in the driving groove toward the steel casing through the action of the guide surface, thereby pushing the reinforcing rod to slide toward the other hinged section, insert into the connecting groove and stabilize in the two hinged sections, thereby improving the stability of the support beam. When the support beam needs to be dismantled, the concrete base plate is lifted, and at this time the reset member drives the reinforcing rod to reset to the corresponding hinged section, and the worker can lift the support beam to complete the dismantling; the reinforcement assembly drives the reinforcing rod to slide through the gravity of the base plate unit, thereby realizing self-locking of the two hinged sections and reducing the use of driving members.

[0015] Preferably, the reset member comprises a spring, the spring is sleeved on the reinforcing rod, one end of the spring is connected to the reinforcing rod, and the other end of the spring is fixed in the sliding groove.

[0016] By adopting the above technical solution, when the workers lift the concrete base plate, the driving block no longer drives the reinforcing rod to be inserted into another hinged section. At this time, the spring drives the reinforcing rod to retract, and the workers can smoothly lift the supporting beam body for recovery.

[0017] Preferably, the hinge point is located on the downward side of the support beam body.

[0018] By adopting the above technical solution, if the hinge point is set at the top, workers need to push the support beam body downward first, so that the two hinged sections can be rotated and completely enter the steel casing before recycling; if the hinge point is set at the bottom, workers can directly lift the support beam body and realize recycling, which speeds up the recycling process.

[0019] Preferably, a hook is fixedly provided on the support beam body, a winch is fixedly provided on the steel casing, a steel hinge rope is fixedly connected to the hook, and one end of the steel hinge rope away from the hook is connected to the winch.

[0020] By adopting the above technical solution, workers hang the steel hinge rope on the supporting beam body through the hook in advance. When the supporting beam body needs to be recovered, the winch can be directly started to speed up the recovery.

[0021] Preferably, a locking bolt is provided on the hook, and the locking bolt is simultaneously passed through the hook tip and the hook body of the hook.

[0022] By adopting the above technical solution, the steel hinge rope is locked in the hook by the locking bolt, thereby reducing the risk of the steel hinge rope being unhooked.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. After the hoisting box is hoisted, it is no longer in contact with the support beam. At this time, the worker pulls the support beam to drive the two hinged sections to rotate relative to each other, and the support beam can be lifted from the steel casing and quickly taken out from under the water. Through this disassembly method, firstly, it can reduce the number of workers stepping over the hoisting box to take the support beam body out of the water, thereby increasing the safety factor of the workers' construction. Secondly, the disassembly structure is simple and convenient for workers to operate.

[0025] 2. After the bottom plate unit is installed on the steel casing, the bottom plate unit abuts against the two driving blocks on the support beam body on the lower side. The two driving blocks are pushed to move in the driving groove toward the steel casing through the action of the guide surface, thereby pushing the reinforcing rod to slide toward the other hinged section, insert into the connecting groove and stabilize in the two hinged sections, thereby improving the stability of the support beam. When the support beam needs to be removed, the concrete bottom plate is lifted. At this time, the reset member drives the reinforcing rod to reset to the corresponding hinged section, and the worker can lift the support beam to complete the removal. The reinforcement assembly drives the reinforcing rod to slide through the gravity of the bottom plate unit, thereby realizing the self-locking of the two hinged sections and reducing the use of driving members.

[0026] 3. The hinge point of the support beam body is set at the bottom, so that workers can directly lift the support beam body for recycling, which speeds up the recycling process. BRIEF DESCRIPTION OF THE DRAWINGS
