The surface of the cast (structure) is smooth and beautiful, does not pollute the concrete surface, and can save the secondary plastering process of the wall surface; it is easy to disassemble and assemble, simple to operate, and the project progresses quickly; it can be made into a curved flat formwork. It is suitable for the top formwork, wall formwork, beam and column formwork, balcony formwork, and non-matting super-bright surface plain concrete formwork of high-rise buildings.
[0003] The joints between the wooden formwork board and the wooden squares are fastened with a row of steel nails. Since there are many joints, steel nails can be seen everywhere on the construction site.
[0004] Therefore, construction workers often need to pull out steel nails from wooden formworks. The traditional tools for pulling out nails are pliers or nail hammers, but they can only pull out one steel nail at a time. Now there are nail pullers on the market, which are generally electric or pneumatic, so they also need to be equipped with power supply equipment or gas supply equipment, which is inconvenient to carry, and nail pullers can only pull out one steel nail at a time.
[0005] In summary, the efficiency of existing nail extraction equipment needs to be further improved. Utility Model Content

In addition, specific features, structures, or characteristics in one or more embodiments may be combined in any suitable form.
[0027] The utility model is further described in detail below in conjunction with the accompanying drawings and embodiments.
[0028] like Figure 1 and Figure 2 As shown, an embodiment of the utility model provides a wood formwork nail cleaning device, which includes: a housing 1 and a working part;
[0029] A plurality of positioning grooves 2 are sequentially arranged on the lower side of the shell 1, and a plurality of support plates 3 are sequentially arranged inside the shell 1, wherein the plurality of positioning grooves 2 and the plurality of support plates 3 are alternately arranged, and one end of the upper side of the shell 1 is fixedly connected to an arc-shaped handle 4, and the center of curvature of the arc-shaped handle 4 faces the other end of the upper side of the shell 1;
[0030] The working part includes a lever 5, a bearing rod 6 and a plurality of nail pulling claws 7. The bearing rod 6 is slidably arranged in the shell 1. The upper ends of the plurality of nail pulling claws 7 are respectively fixedly connected to the axial side of the bearing rod 6. Each of the nail pulling claws 7 corresponds to one of the positioning grooves 2. The upper end of each of the nail pulling claws 7 is connected to one of the support plates 3 through a spring 8, which is used to drive the nail pulling claws 7 to move away from the handle. The lever 5 is arranged on the outer side of the arc-shaped handle 4. The middle part of the lever 5 is rotatably connected to one end of the upper side surface of the shell 1, and the lower end of the lever 5 is hinged to the end of the bearing rod 6.
[0031] A wooden formwork nail cleaning device works as follows:
[0032] When the operator uses the device, the lower side of the shell 1 is pressed against the wooden template so that the multiple steel nails on the wooden template are respectively located at the notch positions of the nail pulling claws 7, and then the lever 5 and the arc handle 4 are held so that the upper end of the lever 5 is pressed against the arc handle 4, and the lower end of the lever 5 drives the load-bearing rod 6 and the nail pulling claw 7 to move, and the nail pulling claw 7 overcomes the elastic force of the spring 8 and approaches the arc handle 4, so that the inner edge of the notch of the nail pulling claw 7 fully clamps the steel nail cap.
[0033] On this basis, the operator pulls the arc handle 4 upwards, so that the shell 1 rotates around the end away from the arc handle 4, so that the multiple steel nails are synchronously separated from the wooden template.
[0034] In the technical solution of the utility model, by using the device, multiple steel nails can be removed at one time, which improves the work efficiency compared with the prior art.
[0035] Specifically, the upper end of the nail-removing claw 7 is welded to the axial side of the bearing rod 6 .
[0036] Specifically, the shell 1 is in the shape of a cuboid, and the arc-shaped handle 4 is fixedly welded to one end of the upper side of the cuboid shell 1 .
[0037] Specifically, the upper and lower ends of the support plate 3 are welded to the inner surface of the shell 1 respectively.
[0038] Specifically, the nail-removing claw 7 is L-shaped, so that a shovel plate is formed at the lower end of the nail-removing claw 7, and the shovel plate is a wedge surface, and a notch is provided at the center line of the shovel plate.
[0039] Specifically, an opening 12 is provided at one end of the upper side surface of the shell 1, and the opposite sides of the opening 12 are respectively fixedly connected to the bracket plates 13. A pivot 14 is provided between the two bracket plates. A hole is provided in the middle of the lever 5, and the pivot 14 is rotatably connected to the hole. The lower end of the lever 5 passes through the opening 12 and is hinged to the end of the load-bearing rod 6.
[0040] In a specific implementation, the distances between any two adjacent nail-removing claws 7 are different.
[0041] In this embodiment, specifically, because the distances between two adjacent steel nails on the wooden template are not the same, and in this device, the distances between each two adjacent nail claws 7 are different, this arrangement can increase the probability that the notches of two of the nail claws 7 hook different steel nail caps at the same time, thereby improving the adaptability of the device when used.
[0042] like Figure 1 and Figure 2 As shown, in a specific embodiment, it further includes a protrusion 9, which is fixedly connected to the housing 1, and the protrusion 9 and the arc-shaped handle 4 are located at the distal ends of each other.
[0043] In this embodiment, specifically, the arc handle 4 is fixedly connected to one end of the upper side of the shell 1, and the protrusion 9 is fixedly connected to the other end of the lower side of the shell 1. When the operator pulls up the arc handle 4, the shell 1 rotates around the protrusion 9, driving the load-bearing rod 6 to rotate, thereby driving multiple steel nails to detach from the wooden formwork through multiple nail-removing claws 7.
[0044] like Figure 1 and Figure 2 As shown, in a specific embodiment, a plurality of arc-shaped grooves are arranged in sequence on the inner side of the arc-shaped handle 4 .
[0045] In this embodiment, specifically, the operator holds the lever 5 and the arc handle 4 from the outside of the arc handle 4, and the operator's fingers just fit into the arc grooves in sequence, matching the functional position of the human hand holding the arc handle 4.
[0046] like Figure 3 and Figure 4 As shown, in a specific embodiment, the bearing rod 6 includes a first bearing rod 601 and a second bearing rod 602 , and opposite sides of the upper end of each nail-removing claw 7 are fixedly connected to the first bearing rod 601 and the second bearing rod 602 , respectively.
[0047] In this embodiment, specifically, the opposite sides of the upper end of each of the nail pulling claws 7 are fixedly connected to the first bearing rod 601 and the second bearing rod 602 respectively. When multiple nail pulling claws 7 hook the steel nails and pull out the steel nails, the first bearing rod 601 and the second bearing rod 602 simultaneously adhere to the lower inner surface of the shell 1, and the nail pulling claws 7 are more stable and will not deviate relative to the shell 1, thereby improving the stability of the nail pulling work.
[0048] Specifically, the first bearing rod 601 and the second bearing rod 602 are slidably disposed on the left and right sides of the supporting plate 3 , respectively.
[0049] like Figures 1 to 4As shown, in a specific embodiment, the end of the bearing rod 6 is fixedly connected to the pin 10 , and the lower end of the lever 5 is provided with a waist hole 11 , and the pin 10 is slidably disposed in the waist hole 11 .
[0050] In this embodiment, specifically, when the operator drives the lever 5 to rotate, the position of the pin 10 in the waist hole 11 can be adaptively changed, so that the rotating lever 5 can stably drive the bearing rod 6 to move horizontally.
[0051] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
