Description

Technical Field

[0001] The invention relates to the technical field of bridge box girder construction, and in particular to a prefabricated beam mold opening operation platform and a use method thereof. Background Art

[0002] At present, there are fewer and fewer newly built expressways, and more and more reconstruction and expansion projects. In order to fit the span and line of the old bridge, and to meet the clearance and width requirements of the overpass road and waterway, the reconstruction and expansion projects have complex beam shapes, various beam heights, beam lengths and angles, and many non-standard beams.

[0003] During the prefabrication of non-standard beams, the side formwork type needs to be frequently replaced or adjusted. The traditional circular production line has a fixed hydraulic formwork mobile trolley tooling, and the formwork is installed in a fixed position. The hydraulic system and construction platform installed on the formwork are very bulky, with many hydraulic oil pipes. Replacing or adding side forms is time-consuming and laborious. When replacing or adjusting the formwork, the casting station needs to be occupied, which causes traffic jams on the production line and affects the efficiency of beam making. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a precast beam mold opening operation platform which is simple and convenient to replace, adaptable to different templates and improves efficiency, and a method for using the same.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A prefabricated beam mold opening operation platform comprises a plurality of construction frames and a hydraulic station matching the number of the construction frames, a mold opening area is formed between two adjacent construction frames, a plurality of hydraulic jacks are movably connected to the construction frames, each of the hydraulic jacks is connected to a corresponding hydraulic station, during the mold opening operation, each of the hydraulic jacks is connected to a template, and the hydraulic station drives the hydraulic jack to return to disassemble the template.

[0007] As a further improvement of the above technical solution:

[0008] The construction frame includes a plurality of columns arranged at intervals, each of which is welded and fixed to a pre-buried steel plate on the ground, a main beam is connected between the columns, a cross beam is fixed to the top of each column, the cross beam is flush with the upper surface of the column, an operating table is fixed to the cross beam and the columns, and each hydraulic jack is movably connected to the main beam.

[0009] The main beam is buckled with a base which can slide and move along the main beam, and the hydraulic jack is movably hinged on the base.

[0010] During the mold opening operation, the piston rod of the hydraulic jack is connected to the template through a latch.

[0011] The operating platform comprises a platform plate and guardrails. The platform plate is fixedly connected to the crossbeam and the column, and the guardrails are arranged on both sides of the platform plate.

[0012] Diagonal braces are also arranged on both sides of the column.

[0013] It also includes a construction staircase, which includes a pedal and a handrail. One end of the pedal is placed on the ground, and the other end is fixedly connected to the beam. The handrail is arranged on both sides of the pedal.

[0014] The hydraulic station is electrically connected to a control cabinet.

[0015] The hydraulic station comprises an oil pump and oil pipes matching the number of hydraulic jacks, and each of the oil pipes is connected between the oil pump and the hydraulic jack.

[0016] A method for using a prefabricated beam mold opening operation platform comprises the following steps:

[0022] Compared with the prior art, the advantages of the present invention are:

[0023] The present invention sets a construction frame and a hydraulic jack on the construction frame. The hydraulic station drives the hydraulic jack to return to disassemble and separate the formwork of the precast beam. The operation is simple and convenient. Compared with the traditional tooling in which the casting construction platform and the hydraulic system are set as one body, the working platform of the present invention separates the hydraulic jack and the casting construction platform. When the formwork is dismantled and the formwork is replaced, the construction position of the casting platform will not be occupied, thereby improving the construction efficiency. In addition, the hydraulic jack is movably connected to the construction frame, so that it can adapt to the disassembly, replacement and adjustment of different types of formwork.
