Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a novel pull-tab removing device. Background Art

[0002] In the actual construction process of the formwork system on the project site, in order to effectively improve the construction efficiency, shorten the construction period, and meet the construction management requirements of "four savings and one environmental protection", the application of new process-based and modular aluminum alloy formwork is increasing day by day, and the application scope is becoming more and more extensive. The pull-tab aluminum alloy formwork system is suitable for super-high-rise buildings or multi-story buildings with a high degree of standardization. It belongs to the quick-disassembly system. During the construction of the concrete wall, the wall formwork on both sides is connected by pull tabs. Each pull tab is designed with through holes on both sides. After the template is adjusted, pins are pinned in the through holes of the pull tab, and finally the pins are driven in to fix it. After the wall concrete is poured and the formwork is removed, the protruding wall pull tabs need to be removed in time.

[0003] For example, a Chinese utility model patent (CN212562519U) discloses a pull-tab type aluminum alloy template pull-tab removal device, which records: "including a pry bar, a handle, a steel plate, and a support block; the steel plate is placed vertically, one side is welded to the handle, and the other bottom side is vertically welded and fixed to the middle of the support block; the pry bar is horizontally arranged at the through hole at the upper left end of the steel plate." However, the above patent uses the method of breaking the pull tab vertically downward, which is more laborious and increases the labor intensity of the staff.

[0024] In order to solve this technical problem, the utility model provides a novel pull-tab removal device, which is applied to a pull-tab type aluminum alloy template;

[0025] It includes a base 1, and support wheels 2 are arranged at the four end corners of the bottom of the base 1.

A clamping assembly is arranged at one end of the connecting frame 8, and a handle assembly is arranged at the other end of the connecting frame 8.

[0026] The novel pull-tab removing device provided by the utility model can break the pull-tab horizontally in half through the overall structural coordination design. Since the pull-tab is relatively thin, it is more labor-saving than breaking the pull-tab vertically downward, thus solving the problem of increased labor intensity of the staff when the original removing device is in use.

[0027] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0028] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings. Example

[0029] Please refer to Figure 1-4 A novel pull-tab removal device comprises a base 1, four end corners of the bottom end of the base 1 are provided with supporting wheels 2, one end of the upper end of the base 1 is symmetrically fixed with a push frame 3, through the supporting wheels 2 and the push frame 3, it is convenient for the staff to push the device to the aluminum alloy template, and the end of the base 1 away from the push frame 3 is symmetrically fixed with a rubber plate 4, through the rubber plate 4, the friction force can be increased after the device is fitted with the aluminum alloy template, so that the position is not easy to shift when the device is used;

[0030] In order to facilitate the breaking and removal of the pull tabs at different heights on the aluminum alloy template, a hydraulic cylinder 6 is fixed to the other end of the upper end of the base 1, and a fixed shaft 7 is fixed to the telescopic end of the hydraulic cylinder 6.

The hydraulic cylinder 6 drives the telescopic rod to drive the fixed shaft 7, the connecting frame 8, the clamping assembly and the handle assembly to adjust the height position, thereby facilitating the breaking and removal of the pull tabs at different heights on the aluminum alloy template;

[0031] Specifically, the clamping assembly includes a fixed frame 9. When the device is attached to the aluminum alloy template, in order to facilitate the clamping of the pull tab and facilitate the subsequent horizontal breaking, a fixed frame 9 is fixed to one end of the connecting frame 8, a sliding column 10 is fixed to the inner side of the fixed frame 9, and a bidirectional screw 11 is rotatably connected to the inner side of the fixed frame 9.

A clamping block 13 is symmetrically threadedly connected to the outer side of the bidirectional screw 11 and located on the inner side of the fixed frame 9, and the clamping block 13 is slidably connected to the sliding column 10.

[0032] Specifically, the grip assembly includes a pry bar 14. After the pull tab is clamped, in order to save effort during the breaking operation, the other end of the connecting frame 8 is provided with a pry bar 14, and the end of the pry bar 14 away from the connecting frame 8 is also fixed with a handle 16. The handle 16 improves the comfort of holding the pry bar 14 and makes it easier to exert force.

[0033] When the device is fitted with the aluminum alloy template, in order to facilitate the positioning of the pull tab so that the pull tab can be located at the center between the two clamping blocks 13, and then the pull tab can be clamped and fixed by the two clamping blocks 13, a positioning plate 5 is also arranged between the two rubber plates 4, and the positioning plate 5 is fixed to the base 1. By moving the device, the positioning plate 5 and the pull tab are driven to be on the same vertical axis, thereby achieving a positioning effect;

[0034] After the pull tab is broken and removed, in order to facilitate collection and storage, a storage slot 20 is provided at the upper end of the base 1 and between the two push racks 3; Example

[0035] The handle assembly provided in Example 1 is further optimized, specifically, as follows Figure 4 As shown, when the handle assembly is not in use, in order to facilitate the storage of the pry bar 14, a rotating shaft 15 is provided at the lower end between the connecting frame 8 and the pry bar 14, and the pry bar 14 is rotatably connected to the connecting frame 8 through the rotating shaft 15. When the pry bar 14 is needed, after the pry bar 14 is turned over and fits with the connecting frame 8 through the rotating shaft 15, in order to facilitate the limiting and fixing of the pry bar 14, a limiting assembly is provided between the pry bar 14 and the connecting frame 8;

[0036] Specifically, the limit assembly includes a fixed seat 17, the upper end of the connecting frame 8 near one end of the pry bar 14 is fixed with the fixed seat 17, the inner part of the fixed seat 17 near one end of the pry bar 14 is slidably connected with a pull rod 18, one side of the pull rod 18 passes through the pry bar 14 and is slidably connected with the pry bar 14, and a spring 19 is fixed between the outer side of the other side of the pull rod 18 and the fixed seat 17, and the elastic characteristics of the spring 19 facilitate automatic reset after the pull rod 18 is pulled;

[0037] The use process of the new pull-tab removal device provided by the utility model is as follows: first, after the device is fitted with the aluminum alloy template, the pull-tab and the positioning plate 5 are on the same vertical axis, and then the hydraulic cylinder 6 is started to drive the fixed shaft 7 to move downward and contract, so that the upper end of the pull-tab is fitted with the bottom end of the fixed frame 9. At this time, the hand valve 12 is rotated to drive the two-way screw 11 to rotate, and then the two clamping blocks 13 are driven to move closer to each other through the limit of the sliding column 10, so that the pull-tab is clamped and fixed, and there is a certain gap between the clamping assembly and the aluminum alloy panel, so that there is room for movement during the subsequent breaking operation. At this time, the handle 16 is grabbed and pushed horizontally, so that the clamping assembly is turned over with the fixed shaft 7 as the axis, and then the pull-tab is broken and removed.
