Abstract
The utility model provides a heat preservation board anchoring nail which comprises an expansion pipe, a screw and a disc. The expansion pipe is provided with a cavity for accommodating the screw, and the disc is fixed at the rear end of the expansion pipe. The heat preservation board anchoring nail is characterized in that a plurality of longitudinal gaps are arranged at the front portion of the expansion pipe, barbs are arranged outside the pipe wall of the expansion pipe among the gaps, protrusions are arranged inside the pipe wall, and a groove for accommodating a nut is formed at the rear end of the expansion pipe. The front portion of the expansion pipe is provided with multiple gaps, the expansion pipe is provided with the barbs and the protrusions, the screw is inserted into the cavity and then extrudes the protrusions, the pipe wall is propped open, and the burrs can well penetrate a heat preservation board. The bearing capacity of the heat preservation board anchoring nail is improved and can reach to more than 0.8KN, and the soundness is good. The groove is formed at the rear end of the expansion pipe and used for accommodating the nut, the exposed portion of the nut after the screw in installed is short, coating of plastering mortar is facilitated, and convenience is brought to later-period construction.
Description
Technical field
The utility model belongs to decoration accessory field, relates in particular to a kind of warming plate anchor nails.
Background technique
Protecting sheet anchor nails is that warming plate is fixed on to a kind of special engineering plastic expansion nail on body of wall.Anchor nails is made up of three parts: the nylon disk on galvanized steel screw and expand tube in expand tube, expand tube that nylon is made.According to the difference of insulation layer thickness, warming plate anchor nails is divided into plurality of specifications, is widely used in building decoration.But existing warming plate anchor nails is installed rear nut and is leaked outside, affects the coating of decorative mortar, and according to the number of plies difference of warming plate, need to use multiple warming plate anchor nails, and anchor nails bearing capacity has to be strengthened.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of warming plate anchor nails, comprise expand tube, screw and disk, in described expand tube, be provided with the cavity for holding screw, described disk is fixed on the rear end of described expand tube, it is characterized in that described expand tube front portion is provided with some longitudinal gaps, the described expand tube tube wall outside between described gap is provided with hangnail, inside is provided with projection, and described expand tube rear end is provided with the groove for holding nut.
Described projection is arc convex.
The quantity in described gap is 3-4.
The beneficial effects of the utility model are: multiple gaps are offered in the front portion of expand tube, and hangnail and projection be set, expression lobes after screw inserts in cavity, tube wall is strutted, hangnail can thrust in warming plate better, improved bearing capacity of the present utility model, more than bearing capacity can reach 0.8KN, soundness is better; In expand tube rear end, groove is set, for holding nut, screw installation rear nut leaks outside partly shorter, is beneficial to the coating of later stage decorative mortar, for construction in later period brings convenience.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
In figure, 1, expand tube; 2, screw; 3, disk; 4, hangnail; 5, projection.
As shown in Figure 1, in expand tube 1, be provided with the cavity for holding screw 2, disk 3 is fixed on the rear end of expand tube 1, and expand tube 1 front portion is provided with four longitudinal gaps, expand tube 1 tube wall outside between gap is provided with hangnail 4, inside is provided with arc convex 5, and expand tube 1 rear end is provided with the groove for holding nut.
When use, screw 2 inserts in the cavity of expand tube 1, and its anterior expression lobes 5, struts the tube wall of expand tube 1 front portion, and most nuts of screw 2 are positioned at groove.
Have been described in detail of the present utility model by embodiment above, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variation and improvement etc. of doing according to the utility model application range, within all should still belonging to patent covering scope of the present utility model.
