Description

Technical Field

[0001] The utility model relates to a forming die for a multi-angle T-beam component, belongs to the technical field of bridge construction, and is used for beam field construction of multi-angle construction. Background Art

[0002] The cross-section of a T-beam component is T-shaped, with flange plates on both sides and a beam rib or web in the middle. This is equivalent to digging out the concrete in the tensile zone of a rectangular beam that does not work to resist bending strength to form a T-beam.

[0003] In traditional construction, the forming mold of the T-beam includes multiple fixed side molds, multiple partition side molds and partition plugging plates; the partition side molds and plugging plates are made into corresponding molds according to different angles. In a project, there are many types of angles of the T-beam partition side molds (angle molds), and partition side molds with different angles need to be replaced, which has high processing costs, high labor intensity, and low efficiency and economy.

[0004] The T-beam prefabrication production line in the beam yard can only complete the prefabrication of the orthogonal partition side formwork, and the T-beam with a certain angle of oblique partition side formwork needs secondary formwork to complete. During the prefabrication process, part of the length of the main reinforcement of the T-beam with the oblique partition side formwork is hidden in the web of the beam body, and other small-diameter steel bars are bent inside the beam body; before the secondary formwork, the surface of the beam body where the partition is to be cast needs to be roughened to expose the steel bars, and the main reinforcement connecting the steel bar sleeve is extended to the theoretical size; the steel bars with small diameters are straightened, and then the oblique partition side formwork is assembled and concrete is poured; the oblique partition side formwork is supported twice on the T-beam body, and the assembly of the oblique partition side formwork is inconvenient to operate and is prone to leakage, making the appearance of the prefabricated T-beam components uneven, and cracks are prone to appear at the contact between the oblique partition concrete and the T-beam body, affecting the overall quality of the T-beam; when the sharp angle of the partition side formwork is removed after the casting is completed, all blunt-angle molds need to be removed, leaving enough space before removing the sharp-angle mold, which is time-consuming and labor-intensive.

[0009] The utility model discloses an opening and closing mold assembly comprising an oil cylinder installed between the back side of an acute angle fixing plate and the top side of a base; the piston rod end of the oil cylinder is connected via an ear seat installed on the back side of the acute angle fixing plate, and the cylinder end of the oil cylinder is connected via a support installed on the top side of the base.

[0010] The utility model installs an adjusting screw between the back side of the obtuse angle mould folding plate and the rear side frame of the side mould A; the nut on the adjusting screw is rotated to rotate the obtuse angle mould folding plate to a corresponding angle.

[0011] The utility model connects the acute angle fixing plate and the acute angle corner mould folding plate, and the obtuse angle fixing plate and the obtuse angle corner mould folding plate through rotating shafts or hinges.

[0012] The partition angle of the utility model is the angle between the center line of the partition and the perpendicular line of the center line of the T beam; the center line of the partition is the line connecting the midpoints of the top edges of the two blocking plates in the groove A and the groove B.

Since the acute angle mold folding plate is hinged with the acute angle fixed plate, and the obtuse angle mold folding plate is hinged with the obtuse angle fixed plate, the acute angle mold folding plate and the obtuse angle mold folding plate can be conveniently rotated, and the partition angle can be conveniently adjusted. The utility model mold makes a set of molds suitable for components of various angles, saves a lot of mold adjustment sections, saves time and labor; and reduces the labor cost of replacing and debugging the mold in the later stage. The use of adjusting screw rods or oil cylinders to open and close the mold is smoother and more stable, protects the mold, prolongs the service life of the mold, and makes the appearance of the component after casting more beautiful. The utility model method can make the partition and the T-beam body cast and formed at one time, thereby improving the overall quality and strength of the T-beam; after the casting is completed, the acute-angle rotating corner mold component of the partition is directly demoulded by the oil cylinder, and the obtuse-angle rotating corner mold component can be directly demoulded, which greatly saves the process.
