Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, in particular to a T-beam diaphragm casting template structure. Background Art

[0002] The T-beam includes a middle beam extending along the longitudinal direction and a top beam connected to the upper end of the middle beam. The top beam outputs the middle beam to both sides along the transverse direction. The middle beam includes a middle beam steel frame and middle beam concrete cast with the middle beam steel frame. Some T-beams have a number of diaphragms distributed along the longitudinal direction on both sides of the transverse direction of the middle beam. The diaphragms include a diaphragm steel frame and diaphragm concrete cast with the diaphragm steel frame. The diaphragm steel frame is connected with the middle beam steel, and the middle beam concrete is cast with the diaphragm concrete. For T-beams with diaphragms, the diaphragms and the middle beams are not cast together at one time, but are subsequently cast by building fixed diaphragm casting molds on both sides of the middle beam. It is troublesome to install and disassemble the diaphragm mold when casting the diaphragms with the existing molds; the connection strength between the diaphragms and the middle beams is poor, and the thick steel bars (transverse steel bars) of the diaphragm steel frame cannot be accurately positioned. Utility Model Content

[0003] The utility model aims to provide a T-beam transverse diaphragm casting template structure in which a transverse diaphragm mold can be conveniently fixed and removed, thereby solving the problem of inconvenience in installing a movable mold during the casting of the existing T-beam transverse diaphragm.

[0004] The above technical problems are solved by the following technical solutions: a T-beam diaphragm casting template structure, the T-beam includes a middle beam extending along the longitudinal bridge direction and a top beam connected to the upper end of the middle beam, the top beam outputs the middle beam along the transverse bridge to both sides, and a plurality of diaphragms distributed along the longitudinal bridge direction are arranged on both sides of the transverse bridge of the middle beam, the middle beam includes a middle beam steel frame and middle beam concrete cast in the middle beam steel frame, the diaphragm includes a diaphragm steel frame and diaphragm concrete cast in the diaphragm steel frame, the diaphragm steel frame is the same as the middle beam steel frame The beam steel bars are connected together, the middle beam concrete is cast together with the cross diaphragm concrete, including a cross diaphragm casting mold for casting the cross diaphragm, the cross diaphragm casting mold includes a bottom mold, two side molds distributed along the longitudinal bridge direction whose lower ends are connected to the bottom mold, and an end mold connecting one end of the two side molds together, the bottom mold is connected to the mobile chassis through a lifting mechanism, the upper ends of the two side molds are connected together through a longitudinal push-pull rod extending in the longitudinal bridge direction, and the longitudinal push-pull rod is hinged together with one end of an upper telescopic push-pull rod that drives the longitudinal push-pull rod to move toward the middle beam. The process of casting the diaphragm is as follows: the diaphragm casting mold is moved by the mobile base to be connected to the position of the middle beam where the diaphragm is set, the height of the diaphragm casting mold is adjusted to the required height by the lifting structure, the diaphragm steel frame is located in the diaphragm casting mold, the upper telescopic push-pull rod is extended to make the diaphragm casting mold close to the middle beam, the diaphragm casting mold and the middle beam form a diaphragm cavity, concrete is poured into the diaphragm cavity and cast together with the diaphragm steel frame to form a diaphragm. Adjusting the mobile cross bar casting mold is convenient, fast and labor-saving, and the diaphragm casting mold can be easily pressed against the middle beam, and the mobile base frames of the aligned diaphragm casting molds on both sides of the middle beam are connected together by the lower pull rod located under the middle beam.

[0005] Preferably, the movable chassis is provided with running wheels, and the bottom mold plate is connected with supporting feet in a lifting manner. When the diaphragm casting mold is moved into place, the supporting feet are extended to support on the ground and the running wheels are lifted off the ground. This can avoid the running wheels moving during the process of the upper telescopic push-pull rod tightening the diaphragm casting mold, resulting in unreliable tightening, thereby improving the reliability of tightening the diaphragm casting mold.

In the process of moving the movable base to make the diaphragm casting mold approach and move away from the middle beam, the diaphragm casting mold is located in the middle of the movable base to improve the stability during the movement; when the movable base approaches the middle beam to the set position, the diaphragm casting mold is moved on the movable base beyond the movable base and abuts against the middle beam. Since the middle beam is supported on the casting bottom mold during casting, the casting bottom plate exceeds the middle beam along the horizontal bridge direction, so that the side of the diaphragm casting mold facing the middle beam during the hinge process will exceed the mobile base, resulting in poor stability during mobile storage. This technical solution can ensure stable movement, and the diaphragm casting mold can reliably abut against the middle beam when in use.

[0007] Preferably, the lifting mechanism comprises a base frame connected to the movable base in a lateral direction, a longitudinal hinge shaft extending in a longitudinal direction, and two groups of support rods distributed in the longitudinal direction, one group of support rods has two support rods and the middle part is cross-connected by the longitudinal hinge shaft, the lower end of the support rod is connected to the base frame in a lateral direction, and the upper end is connected to the bottom template in a lateral direction, the upper end of one of the two support rods in the two groups of support rods is rotatably connected to the first longitudinal connecting rod, and the upper end of the other support rod is rotatably connected to the second longitudinal connecting rod, the first longitudinal connecting rod is rotatably connected to one end of the pull rod, the second longitudinal connecting rod is threadedly connected to the middle screw of the pull rod, and the other end of the pull rod is provided with a crank. When in use, the lifting and lowering of the lifting mechanism is realized by turning the crank, which is convenient for lifting and lowering.

[0008] Preferably, the top beam includes a top beam steel bar skeleton and top beam concrete cast on the top beam steel bar skeleton, both ends of the top beam steel bar skeleton along the transverse direction of the bridge are exposed to the top beam concrete to form an exposed portion, and the upper end of the upper telescopic push-pull rod is rotatably connected to an axle pin fixed to the exposed portion. It is convenient and reliable to fix the upper telescopic push-pull rod, and it occupies little space.

[0009] Preferably, the side formwork is movably connected to the longitudinal push-pull rod along the longitudinal bridge direction, the lower end of the side formwork is hinged to the bottom formwork, the upper end is hinged to the upper end of the side telescopic push-pull rod, the lower end of the side telescopic push-pull rod is hinged to the bottom formwork, and the end formwork is detachably connected to the side formwork. When demoulding, the end formwork is first removed, and then the side telescopic push-pull rod is retracted to disengage the side formwork from the transverse partition, and the top telescopic push-pull rod is retracted to disengage the side formwork from the middle beam. Demolding is convenient.
