Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a device for recovering iron nails of a wooden formwork. Background Art

[0002] Building formwork is a temporary supporting structure, manufactured according to design requirements, which allows concrete structures and components to be formed according to specified positions and geometric dimensions, maintain their correct positions, and bear the deadweight of the building formwork and external loads acting on it.

[0003] The building formwork is fixed and installed by screws, and the building formwork can be reused. When the building formwork is reused, the iron nails on the building formwork need to be removed for recycling. When the iron nails are removed for recycling, the iron nails are prone to bend to a large extent during the removal process, thereby reducing the quality of the iron nail recycling. Utility Model Content

[0004] The utility model aims to solve the disadvantages in the prior art that the nails are easily bent to a large extent during removal, thereby reducing the quality of nail recovery, and proposes a wooden template nail recovery device.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A wooden formwork nail recovery device is designed, comprising a first fixed block, wherein:

[0007] One side of the first fixed block is fixedly connected to two symmetrically arranged plug blocks, a nail-lifting groove is provided between the two symmetrically arranged plug blocks, the bottom end of the first fixed block is slidably connected to an arc block, the upper end of the arc block is rotatably connected to a threaded rod, the bottom end of the first fixed block is provided with a threaded hole, the threaded rod cooperates with the threaded hole, and the second fixed block is fixedly connected to the threaded rod.

[0008] Preferably, the first fixing block and the inserting block are an integral structure.

[0009] Preferably, the spacing between the notches of the nail removal grooves gradually decreases along the length direction of the insert block.

[0010] Preferably, a handle is fixedly connected to the upper end of the first fixing block.

[0011] Preferably, an anti-drop block is fixedly connected to the upper end of the handle.

[0012] Preferably, the first fixed block is connected with an anti-stuck mechanism for preventing the nail from being stuck in the nail pulling groove, the anti-stuck mechanism includes a spring, one end of the spring is fixedly connected to the first fixed block, the other end of the spring is fixedly connected to a push block, the push block is located at the upper end of the nail pulling groove, one end of the push block is connected to two parallel connecting plates, and the two parallel connecting plates can be slidably inserted into the first fixed block.

[0013] Preferably, the other end of the push block is provided with an inclined surface.

[0014] The utility model provides a wooden formwork nail recovery device, which has the following beneficial effects:

[0015] The threaded rod is driven to rotate by the second fixed block, and the arc block moves downward after the threaded rod rotates. The bottom end of the arc block is lower than the bottom end of the plug block, and the fixed block drives the plug block to rotate upward. After the plug block rotates upward, the iron nail is pulled to separate the iron nail from the wooden template, and the distance between the bottom end of the arc block and the bottom end of the plug block is increased, thereby increasing the active radius of the plug block, reducing the curvature of the iron nail when taking the nail, and improving the quality of the iron nail.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Example 1

[0023] Reference Figure 1-3 , a wooden formwork nail recovery device, comprising a first fixing block 1, wherein:

[0024] One side of the first fixed block 1 is fixedly connected to two symmetrically arranged plug blocks 2, the first fixed block 1 and the plug block 2 are an integral structure, a nail-removing groove 3 is provided between the two symmetrically arranged plug blocks 2, and the notch spacing of the nail-removing groove 3 gradually decreases along the length direction of the plug block 2, the bottom end of the first fixed block 1 is slidably connected to an arc block 4, the upper end of the arc block 4 is rotatably connected to a threaded rod 5, the bottom end of the first fixed block 1 is provided with a threaded hole, the threaded rod 5 cooperates with the threaded hole, the second fixed block 6 is fixedly connected to the threaded rod 5, the upper end of the first fixed block 1 is fixedly connected to a handle 7, and the upper end of the handle 7 is fixedly connected to an anti-drop block 8.

[0025] Working process: when the iron nails on the wooden template are removed and recycled, the threaded rod 5 is driven to rotate by the second fixed block 6. After the threaded rod 5 rotates, the arc block 4 moves downward, so that the bottom end of the arc block 4 is lower than the bottom end of the plug block 2, and then the upper end of the iron nail is located in the nail removal groove 3, and the opposite side of the two plug blocks 2 contacts the lower surface of the upper end of the iron nail, and the bottom end of the arc block 4 contacts the wooden template, pushing the handle 7, and the handle 7 drives the first fixed block 1 to rotate, and the first fixed block 1 rotates around the arc block 4, and the first fixed block 1 drives the plug block 2 to rotate upward. After the plug block 2 rotates upward, the iron nail is pulled, so that the iron nail is separated from the wooden template, and the iron nail is recycled. The arc block 4 is driven downward by the threaded rod 5, and the bottom end of the arc block 4 is lower than the bottom end of the plug block 2, so that the distance between the bottom end of the arc block 4 and the bottom end of the plug block 2 is increased, thereby increasing the activity radius of the plug block 2, reducing the curvature of the iron nail when taking out the nail, and improving the quality of the iron nail.

[0026] Example 2

[0027] When the iron nail is removed and recovered by rotating the insert block 2, the iron nail is easily stuck in the nail removal groove 3, which makes it inconvenient to remove the iron nail from the nail removal groove 3. Figure 4As another preferred embodiment of the utility model, on the basis of embodiment 1, the first fixed block 1 is connected with an anti-stuck mechanism 9 for preventing the iron nail from being stuck in the nail removal groove 3, and the anti-stuck mechanism 9 includes a spring 91, one end of the spring 91 is fixedly connected to the first fixed block 1, and the other end of the spring 91 is fixedly connected to a push block 92, the push block 92 is located at the upper end of the nail removal groove 3, and one end of the push block 92 is connected to two parallel connecting plates 93, and the two parallel connecting plates 93 can be slidably plugged into the first fixed block The push block 92 is provided with an inclined surface at the other end, and the iron nail is removed by rotating the insert block 2. The inclined surface of the push block 92 squeezes the iron nail. After the push block 92 is blocked by the iron nail, it slides on the first fixed block 1 through the connecting plate 93. The push block 92 squeezes the spring 91, and the spring 91 generates an elastic force after being compressed. After the iron nail is removed from the wooden template, the elastic force generated by the spring 91 pushes the push block 92, and the push block 92 pushes the iron nail on the nail removal groove 3, so that the iron nail is separated from the nail removal groove 3, which is convenient for removing the iron nail from the nail removal groove 3.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
