Technical Field

[0001] This utility model relates to the field of bridge construction technology, specifically to a formwork for the construction of hollow thin-walled piers that is easy to dismantle. Background Technology

[0002] Hollow thin-walled piers differ from traditional solid piers in that they can reduce masonry work by about 50%. They can be formed by assembling templates, steel sleeves, and inner cores to create a space for pouring, and then pouring in concrete mortar. After it solidifies, it can form a high-strength, lightweight pier column.

[0003] To prevent the space inside the template from shrinking, an inner core needs to be inserted into the mold made of templates before pouring. After the poured material inside solidifies, it is removed. However, most of the inner cores of this type of template in the past lacked auxiliary tools. If the inner core is inserted too deeply, it will be difficult to lift and there is a risk of breakage.

[0004] Now, a new type of formwork for the construction of hollow thin-walled piers that is easy to dismantle is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a formwork for the construction of hollow thin-walled piers that is easy to dismantle, so as to solve the problem of the inner core being inconvenient to remove as mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a formwork for constructing hollow thin-walled piers that is easy to dismantle, comprising a top plate, an inner core longitudinally welded at the center of the bottom of the top plate, a template one longitudinally arranged at the front and rear ends of the bottom of the top plate, template two longitudinally arranged on both sides of the bottom of the top plate, a support rod longitudinally welded at the center of both sides of the bottom of the top plate, and a connecting block fixed at the bottom of the support rod, a slider fixed on the side of the connecting block, a slide rail longitudinally arranged at the center of the outer side of template two, and a toothed groove arranged between the upper and lower parts of the inner side of the slide rail, a gear movably connected inside the side of the slider, and ball bearings movably embedded on the surface of the front and rear ends of the slider.

[0007] As a further technical solution of this utility model, the gear meshes with the tooth groove, and the outer sides of the ball are respectively attached to the front and rear ends of the inner wall of the slide rail.

[0008] As a further technical solution of this utility model, slots are provided longitudinally on both sides inside the first template, and insert rods are fixed longitudinally on both sides of the surface of the second template. Assembly pieces are welded to the lower outer sides of both the first and second templates.

[0009] As a further technical solution of this utility model, the insertion rod is embedded inside the slot, and the insertion rod moves up and down along the inner wall of the slot.

[0010] As a further technical solution of this utility model, a rectangular groove is provided on the lower surface of the top plate, and slides are provided laterally at the front and rear ends of the rectangular groove. A screw hole is distributed between the left and right sides of the slide. A positioning rod is movably connected between the front and rear sides of the rectangular groove. A fixing bolt is threaded to the front and rear ends of the side of the positioning rod. A screw hole is distributed between the front and rear sides of the positioning rod. A mounting plate is laterally fixed to the top of the inner core, and fastening bolts are threaded to the four corners of the mounting plate.

[0011] As a further technical solution of this utility model, the fastening bolt is embedded between the mounting plate and the second screw hole, and the fixing bolt is embedded between the positioning rod and the first screw hole.
