Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, specifically to a bridge support prestressing structure. Background Technology

[0002] During bridge construction, the stability and deformation of the cast-in-place scaffolding are key parameters for the overall stability and safety of the bridge. To ensure that the scaffolding meets construction technical requirements, pre-stressing tests are necessary to assess its stability and essentially eliminate inelastic deformation.

[0003] Existing support preloading methods use sandbags or steel ingots and counterweights, which have the following drawbacks: long hoisting and installation time, and difficulty in disassembly after use; uneven load distribution leading to measurement errors, and also posing a risk of falling objects from heights. Utility Model Content

[0004] In view of the above-mentioned technical deficiencies, the purpose of this utility model is to provide a bridge support preloading structure to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a bridge support preloading structure, including a support component and a water storage structure disposed on the support component. The water storage structure includes a detachable support frame and a water storage bladder disposed within the support frame. The support component is also provided with a water supply component for supplying water to and draining water from the water storage bladder.

[0006] Preferably, the support assembly includes a workbench and a support column disposed at the bottom of the workbench, with pulleys installed at the bottom of the support column.

[0007] Preferably, the support frame has fixing rings around its interior for securing the water storage bladder.

[0008] Preferably, the water supply assembly includes a fixing rod and an inlet pipe and an outlet pipe disposed on the fixing rod.

[0009] Preferably, both the inlet pipe and the outlet pipe are connected to a connecting hose, which passes through the support frame and connects to the water storage tank.

[0010] Preferably, the support frame is further provided with a cover plate, which is located on the water storage bladder, and a rotating pressure strip is also provided on one side of the support frame.

[0011] The beneficial effects of this utility model are as follows: This utility model realizes the rapid movement of the pre-stressed structure between bridge sections by cooperating with pulleys and preset slide rails, and by replacing the traditional counterweight handling with water storage bladder injection and drainage, it greatly reduces hoisting time and labor costs.

[0012] This utility model's water storage bladder utilizes the self-leveling properties of liquid to evenly transmit pressure to the support, effectively solving the stress concentration problem caused by traditional sandbag / steel ingot stacking; the fixing rings and ropes position the four corners of the water storage bladder to further prevent displacement and improve the accuracy of deformation measurement data.

[0013] This invention eliminates the need for hoisting heavy counterweights such as sandbags and steel ingots, thereby reducing the risk of falling objects from heights and improving construction safety.

[0014] This invention replaces complex heavy objects with reusable water storage tanks and support frames, and its modular structure facilitates disassembly and transportation. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example:

[0023] like Figures 1-4As shown,

[0024] This utility model provides a bridge support preloading structure, including a support assembly and a water storage structure disposed on the support assembly.

[0025] In this embodiment, the support assembly includes a workbench 11 and a support column 12 disposed at the bottom of the workbench 11. A pulley 13 is installed at the bottom of the support column 12. During use, a slide rail can be pre-set under the bridge to allow the pulley 13 to roll on the slide rail, driving the entire preloading structure to move along the slide rail. By setting the pulley 13, it is convenient to preload the bridge in sections using the entire structure. A stopping structure can also be provided on the support column 12 or the pulley 13 to stop the pulley 13 from sliding. The stopping structure is existing technology, and therefore, this utility model will not elaborate on this structure.

[0026] The water storage structure includes a detachable support frame 21 and a water storage bladder 22 set inside the support frame 21. The support frame 21 is a metal frame with an opening at the top. The metal is not limited and can be stainless steel. Fixing rings 23 are set around the inside of the support frame 21. The fixing rings 23 are tied to the four corners of the water storage bladder 22 by ropes, so that water can be evenly filled into the water storage bladder 22.

[0027] The support assembly is also equipped with a water supply assembly. Specifically, the water supply assembly includes a fixing rod 31 and an inlet pipe 32 and an outlet pipe 33 mounted on the fixing rod 31. The inlet pipe 32 is located above the outlet pipe 33. The inlet pipe 32 and the outlet pipe 33 can be welded and fixed to the fixing rod 31. The size of the inlet pipe 32 and the outlet pipe 33 is not limited. The inlet pipe 32 and the outlet pipe 33 are shown with different orifice sizes in the attached drawings of this embodiment for easy differentiation.

[0028] Both the inlet pipe 32 and the outlet pipe 33 are connected to a connecting hose 34. The connecting hose 34 shown in the attached drawings of this embodiment has different orifice sizes on the inlet pipe 32 and the outlet pipe 33 for easy differentiation. In actual use, the orifice sizes can be the same. The connecting hose 34 passes through the support frame 21 and connects to the water storage tank 22.

[0029] A cover plate 24 is also provided on the support frame 21. The cover plate 24 is located on the water storage bladder 22. A rotating pressure strip 25 is also provided on one side of the support frame 21. The pressure strip 25 is rotatably connected to the support frame 21 by a pin.

[0030] A solenoid valve is installed at the connection between the connecting hose 34 and the support frame 21. A contact sensor is installed on the side of the pressure strip 25 near the cover plate 24. When the liquid level in the water storage tank 22 rises, the cover plate 24 rises accordingly to contact the pressure strip 25, triggering the contact sensor and generating a sensing signal, which is transmitted to the control system. The control system then uses the solenoid valve to cut off water intake, preventing the water storage tank 22 from rupturing due to excessive water filling. The control system is existing technology, therefore, it will not be described in detail here. Preferably, the control system is a combination of a programmable logic controller and control buttons.

[0031] Working principle:

[0032] When using the bridge support preloading structure provided by this utility model, the support assembly is moved to a designated position, the cover plate 24 is placed on the water storage bladder 22 in advance, the pressure strip 25 is rotated above the cover plate 24, the control system is started, and water is injected into the water storage bladder 22 through the water supply assembly. When the water storage bladder 22 gradually expands and causes the cover plate 24 to contact the contact sensor on the pressure strip 25, the control system stops the water inlet through the solenoid valve. When the bridge preloading work is completed, the control system is started and the water is drained through the water supply assembly.

[0033] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
