Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to a lifting and demolding system. Background Technology

[0002] For example, Chinese invention patent application publication number CN 113530217 A discloses a slipform platform for the construction of beam-slab concrete structures, including a lifting frame. Outer and inner formwork are respectively installed on both sides of the bottom of the lifting frame. A jack is fixedly connected to the top of the lifting frame. Steel trusses are fixedly connected to both sides of the lifting frame. A horizontal measuring component is installed on one side of the lifting frame and fixedly connected to the top of the steel truss. Vertical measuring components are installed on both sides of the top of the lifting frame to measure the verticality of the lifting frame. However, this demolding method is inconvenient for storing the formwork, and the formwork can only move along the length of the beam, not along its width. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a lifting and demolding system, which is conducive to storing the demolded template, separating the bottom template and the side template of the beam, storing them in the open space, and then moving them as a whole along the width of the beam, so as to facilitate the simultaneous pouring of the beam and slab structure in the next construction section.

[0004] To solve the above problems, a lifting and demolding system is adopted, which includes:

[0005] Truss beams are spaced apart, forming an open space between adjacent truss beams;

[0006] The U-shaped frame is set between the truss beams in the open space. It includes two vertical tubes on both sides and a horizontal tube at the bottom. The upper end of the vertical tube is lower than the top surface of the truss beam to reserve storage space. The vertical tube is fixed to the side of the truss beam.

[0007] A portal frame is installed above a U-shaped frame. Multiple portal frames spaced back and forth are connected as a whole by longitudinal beams on both sides of the top. The uprights on both sides of the portal frame are slidably installed in the uprights on both sides of the U-shaped frame, and the top crossbeam is between the longitudinal beams on both sides.

[0008] The hydraulic jack is installed on the bottom horizontal tube of the U-shaped frame, and its upper piston head is fixed to the bottom surface of the top horizontal beam of the portal support frame.

[0009] With this structure, the elevated floor can be used to stack the bottom formwork of the slab and the side formwork of the beam; hydraulic jacks can drive the portal frame to move down, and the portal frame is used to fix the bottom formwork of the slab; after the limit of the portal frame and the U-shaped frame is released, the column can move in the riser; the bottom formwork of the slab is spliced ​​with the corner formwork and the side formwork of the beam, and after the limit of the bottom formwork and the corner formwork is released, the bottom formwork of the slab can be demolded by the hydraulic jack first; after the side formwork of the beam is removed, it is placed on the bottom formwork of the slab; the bottom formwork of the beam is fixed on the truss beam; after the bottom formwork of the slab and the side formwork of the beam are placed in the storage space, it will still not be higher than the bottom elevation of the beam, so the whole structure can slide along the width of the beam and move to the next construction section.

[0010] As a further improvement of this utility model, longitudinal support beams are fixed to the inner sides of the two side uprights of the U-shaped frame, and spaced support plates are installed on the support beams; hydraulic jacks extend between the support plates.

[0011] With this structure, the support plate is used to hold the bottom mold of the slab. After the hydraulic jack retracts, the support plate can support the bottom mold of the slab.

[0012] As a further improvement of this utility model, the column and riser are provided with bolt holes at corresponding positions and are equipped with detachable limiting bolts.

[0013] With this structure, when the portal frame supports the bottom mold plate, a limit bolt can be inserted through the bolt hole to achieve the limit between the portal frame and the U-shaped frame; when demolding, the limit can be released, which is conducive to the demolding of the hydraulic jack.

[0014] As a further improvement of this utility model, a groove is formed around the piston head, the groove has a C-shaped cross-section, and a movable head is slidably assembled in the groove; a crossbar is fixed to the outside of the movable head, and a cross plate is fixed to the outer end of the crossbar; the cross plate slides between two support plates; the two support plates are fixed to the bottom surface of the crossbeam of the portal frame, and an elongated hole is formed on the support plate, with sliding shafts on both sides of the cross plate extending into the elongated hole.

[0015] With this structure, the movable head can rotate along the groove to adjust the support position and ensure parallelism with the crossbeam; the sliding shaft can move along the elongated hole to adjust the extension length to adapt to the length of the crossbeam and prevent the crossbeam from being easily broken due to a single or too close stress point.

[0016] As a further improvement of this utility model, triangular stiffening plates are provided between the longitudinal beam and the column, and between the crossbeam and the column.

[0017] This structure strengthens the joints of the portal frame.

[0018] As a further improvement of this utility model, a horizontal pipe is fixed to the side of the riser so that the column can slide downwards and extend from the riser.

[0019] With this structure, the horizontal tube is fixed to the side of the vertical tube, which does not affect the column extending downward through the vertical tube and helps to increase the telescopic distance.

[0020] As a further improvement of this utility model, guide wheel moving components are installed at the bottom of both ends of the truss beam, and the guide wheel moving components are installed on the track; the track is installed on the unloading block, and the unloading block is installed on the pre-embedded corbel of the lattice column and the structural column.

[0021] With this structure, the guide wheel moving assembly facilitates the overall movement along the track, and the unloading block facilitates the overall descent or elevation, which is conducive to the demolding of the bottom formwork of the beam. It prevents the demolded formwork from hitting the bottom of the beam during the overall movement, and helps to keep the overall structure below the bottom elevation of the beam. After moving to the next construction section, the unloading block is adjusted so that the bottom formwork of the beam moves to the bottom elevation of the beam.

[0022] As a further improvement of this utility model, a ladder frame is also installed at the upper end of the lattice column.

[0023] This structure makes the ladder frame easier for construction workers to use.

[0024] This invention facilitates the storage of the demolded template, separating the bottom template and the side template of the beam, storing them in the elevated layer, and then moving the whole structure along the beam width direction, which makes it convenient to simultaneously pour the beam and slab structure in the next construction section.
