Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings 1 to 4.
The invention relates to a folding core mould of a hollow slab beam for highway construction, which structurally comprises a support rod 1, a unidirectional movable hinge 2, a steel bar bracket and square steel 3, the steel bar supports comprise a plurality of steel bar supports which are divided into transverse steel bar supports 4 and longitudinal steel bar supports 5, the transverse steel bar supports 4 and the longitudinal steel bar supports 5 are arranged at intervals from front to back along the axis direction of the support rod 1, and every two transverse steel bar supports 4 form a group, the symmetrical setting is in the left and right sides of bracing piece 1, and every two vertical steel bar support 5 are a set of, and the symmetry sets up in the upper and lower both sides of bracing piece 1, links to each other through one-way movable hinge 2 between every horizontal steel bar support 4, vertical steel bar support 5 and the bracing piece 1 respectively, and the periphery of horizontal steel bar support 4 and vertical steel bar support 5 is provided with square steel 3, and the shape that horizontal steel bar support 4 and vertical steel bar support 5 periphery formed is identical with the interior storehouse shape of cavity board.
Every horizontal steel bar support 4, vertical steel bar support 5 include vertical reinforcing bar 41, horizontal reinforcing bar 42, slant reinforcing bar 43 and strengthening rib 44 respectively, vertical reinforcing bar 41 one end and one-way movable hinge 2 link to each other, the other end links to each other with horizontal reinforcing bar 42, horizontal reinforcing bar 42's both ends are provided with slant reinforcing bar 43 respectively, be provided with strengthening rib 44 between slant reinforcing bar 43 and the vertical reinforcing bar 41, the shape that horizontal reinforcing bar 42 and slant reinforcing bar 43 are constituteed is identical with hollow slab inner bin shape. Around steel bar support full-spread rectangle square steel 3, 3 sizes of square steel can select for use in a flexible way to adjust out storehouse structure size in the hollow plate, less model square steel 3 or channel-section steel can be used in the cooperation of chamfer department.
The vertical reinforcing steel bars 41, the transverse reinforcing steel bars 42 and the oblique reinforcing steel bars 43 are made of phi 16mm thread steel.
One end of the unidirectional movable hinge 2 is fixed with the support rod 1, and the other end of the unidirectional movable hinge is fixed with the steel bar support. The hinge has a movable angle of 90 degrees.
The support rod 1 is composed of a plurality of sections, and each section is 4-6m long. The sections are hinged through pins. The length can be conveniently adjusted at any time according to the size requirement.
The distance between the adjacent transverse reinforcing steel bar supports 4 and the longitudinal reinforcing steel bar supports 5 is 1 m.
The support rod 1 is made of square steel 3 with the thickness of 30 multiplied by 50 multiplied by 4 mm.
The peripheral square steel 3 is temporarily fixed with the steel bar bracket by using a binding wire; in order to prevent the instability of the steel bar support, the steel bar support and the central support rod 1 are temporarily fixed by binding wires. When the core mould is drawn out, the temporary fixing tie wire can be easily broken, and the phenomenon that the fixing is too firm is avoided. On 1 axis direction along the bracing piece, link to each other through pricking the silk between the steel bar support of homonymy, rotate one when the manual work, can drive a plurality of rotations simultaneously, and then make steel bar support close or expand simultaneously.
Because the surface of the core mould is formed by assembling a plurality of square steels 3, a circle of plastic cloth can be uniformly wound around the core mould in order to prevent the mould from sticking or slurry leakage.
The protective layer is controlled by arranging concrete cushion blocks on two sides of the core mold, and the upper part of the core mold is prevented from floating upwards by adopting a traditional pressing bar mode.
When the hinge drives the steel bar support to unfold, the hollow slab core mold is formed; when the hinge drives the steel bar support to be closed, the outer square steel 3 is retracted, the mandrel can be smoothly drawn out through the winch or the sling, and people do not need to enter the mandrel.
By adopting the hollow slab core mould for construction, the construction cost is saved, the working efficiency is improved, the operation environment of operators is improved, the hollow slab core mould is commented on consistently and is widely popularized on the whole line.
The above-mentioned embodiments are only for understanding the present invention, and are not intended to limit the technical solutions of the present invention, and those skilled in the art can make various changes or modifications based on the technical solutions described in the claims, and all equivalent changes or modifications should be covered by the scope of the claims of the present invention. The present invention is not described in detail, but is known to those skilled in the art.
