Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a special nail punching device for installing a wooden template used in a confined space. Background Art

[0002] Plywood wooden formwork has the advantages of light weight, large board width, low cost, flat board surface, and easy and convenient construction and installation. Although the turnover rate and usage quality are lower than those of aluminum formwork or other finished formwork with greater rigidity, wooden formwork plays an irreplaceable role in some structural dimensions and shapes with complex changes and variable cross-section special-shaped structures. When fixing wooden formwork at the inner corners of some wider structural members, due to the narrow working surface and the obstruction of steel bars, the hands holding the nails have no operating space for positioning. When using a nail hammer to fix the nails, the workers cannot fix the nails by hammering them normally, and it is inconvenient to hammer them. Therefore, when installing wooden formwork on wider and larger structural members, it is necessary to solve the problem of effective and reliable positioning of the nails.

[0003] When fixing the iron nails of the formwork at the inner corners of columns and beams, the operator is blocked by the shear wall reinforcement, column reinforcement and beam reinforcement, and the nails cannot be effectively fixed, making it difficult to ensure the overall stability and reliability of the formwork, and loose concrete may easily leak out of the formwork after pouring. Utility Model Content

By arranging hollow iron parts, impact nails, connecting screw sleeves, hammer caps and magnetic parts, the utility model solves the problem that when fixing the iron nails of the formwork at the inner corners of columns and beams, the operator is blocked by the shear wall reinforcement, column reinforcement and beam reinforcement, and the nails cannot be effectively fixed, making it difficult to ensure the overall stability and reliability of the formwork, and the formwork is prone to loose concrete leakage after pouring.

[0005] To achieve the above purpose, the utility model is implemented through the following technical scheme: a special punching nail device for installing wooden formwork used in confined spaces, comprising a hollow iron piece, an impact nail is inserted into the interior of the hollow iron piece, one end of the impact nail is threadedly connected to a connecting nut, one end of the connecting nut is fixedly connected to a hammer cap, an installation groove is opened on one side of the surface of the hollow iron piece, and an iron-absorbing magnetic part is fixedly installed inside the installation groove.

[0006] Preferably, one end of the surface of the hollow iron piece and the surface of the connecting screw sleeve are both provided with threads, and a nut is threadedly connected to the surface of the threads.

[0007] Preferably, the length of the hollow iron piece is 500 mm, the outer diameter of the hollow iron piece is 14 mm, and the inner diameter of the hollow iron piece is 8 mm.

[0008] Preferably, the length of the impact nail is 600 mm, and the diameter of the impact nail is 5 mm.

[0009] Preferably, the lengths of the two screw threads are both 30 mm, and the length of the nut is 14 mm.

[0010] Preferably, the thickness of the magnetic component is the same as the wall thickness of the hollow iron component.

[0011] The utility model provides a special impact nail device for installing wooden formwork used in a confined space, which has the following beneficial effects:

[0012] During use, pull out the impact nail a certain distance outward, then insert the formwork iron nail into the hollow iron component, and adsorb the iron nail through the magnetic component to avoid the problem of the iron nail falling during operation, so as to facilitate the operation of personnel. Then insert this device between the column reinforcements and align the nailing position, and then use a nail hammer or the like to strike the hammering cap, so that the impact nail impacts the iron nail and nails the iron nail into the connection part of the wooden formwork, realizing the fixing effect of the wooden formwork and avoiding the situation of concrete leakage due to the loose formwork after pouring. After use, the connection between the hollow iron component and the connecting sleeve can be connected through the nut, so as to realize the fixing effect of the two, thus facilitating the personnel to carry this device.
