Description

Technical Field

[0001] The utility model relates to the field of construction equipment, and particularly relates to a formwork removal device for building construction projects. Background Art

[0002] With the gradual development of the construction industry, aluminum formwork is widely used in building construction due to its light weight, easy to be produced in a standardized form, and reusable. During the construction of concrete wall formwork, aluminum formwork pull tabs are usually used to fix the inner and outer formwork of the wall, and then concrete is poured. When the concrete strength meets the specification requirements, the formwork can be removed. The middle section of the pull tab is permanently embedded in the concrete, and both ends are exposed on the wall surface, and the ends need to be removed.

[0003] The Chinese utility model patent with the publication number [CN208310229U] discloses a special tool for removing the end of the formwork pull tab, which is composed of a working end, a connecting section, and a handle. The working end is located at the front end, the connecting section is installed at the rear of the working end and welded to it, and the handle is installed at the rear of the connecting section and is sleeved and connected with it; a rectangular notch matching the end of the pull tab is arranged at the front of the working end, and the notch is used to clamp and break the end of the pull tab; a notch is arranged at the front end of the connecting section, and a jack is arranged at the rear; the handle is integrally formed into an L shape by a connecting transition rod and a holding rod that are perpendicular to each other, and anti-slip patterns are processed on the side surface of the holding rod end. This tool has a light structure and is easy to operate, reducing the labor intensity of workers.

[0004] However, a rectangular notch is arranged at the front of the working end of this patent. When in use, the rectangular notch needs to be aligned with the end of the pull tab. However, the rectangular notch is small, and it is difficult to quickly align and insert into the end of the pull tab, and multiple alignments are required, which is rather troublesome. Summary of the Utility Model

[0006] The technical solution is that it includes a crowbar and a crowbar head detachably connected to the crowbar. One end of the crowbar is provided with a handle, and the other end is provided with a bent portion. One end of the bent portion of the crowbar is provided with a jack, and the crowbar head is detachably arranged in the jack.

[0007] The crowbar head is in the shape of a rectangular block, and a crowbar groove is arranged on one side of the crowbar head, and the crowbar groove is used to clamp and break the end of the pull tab.

[0008] An insertion rod is fixedly arranged on the crowbar head, and the insertion rod is inserted into the jack, and the crowbar head is detachably connected to the crowbar through the insertion rod and the jack.

[0009] Preferably, a through hole is opened on one side of the crowbar head, and a clamping block is rotatably arranged in the through hole, and a swing arm is arranged at one end of the clamping block.

[0010] One end of the crowbar close to the handle is provided with a control handle, and a wire is arranged between the control handle and the swing arm.

[0011] Preferably, a plurality of spiral grooves are arranged in an array on the outer wall of the clamping block;

[0012] A plurality of limiting balls are fixedly arranged on the inner wall of the through hole, and each limiting ball is in one of the spiral grooves.

[0013] Preferably, the cross-sectional shape of the jack is a regular polygon, and the cross-sectional shape of the plug rod corresponds to the cross-sectional shape of the jack.

[0014] The beneficial effects brought by the technical solution provided by the embodiment of the present invention are as follows: By using the lever principle, the reinforcement pull tab exposed on the wall surface is broken, so as to achieve the purpose of demolition. It is convenient to use and greatly improves the work efficiency; the pry groove is relatively wide, which is convenient for the quick insertion of the end of the pull tab. At the same time, it can clamp the end of the pull tab more firmly, avoid slipping during the demolition process, and improve the stability and safety of the demolition.
