Abstract
The utility model provides an aerated concrete lays bricks and uses fastener, belongs to fastener technical field. It includes the fastener body, this internal screwed connection hole that sets up of fastener, fastener body and screwed connection hole are the cylinder structure of reducing, hold to the increase of major diameter end diameter continuity from the minor diameter, and fastener body surface evenly sets up the heliciform connecting plate, and heliciform connecting plate one end is flat mutually with the large diameter one end terminal surface of fastener body. By adopting the above technique, the utility model, obtain aerated concrete lays bricks and uses fastener, squeeze into this aerated concrete lays bricks and uses fastener in the gas concrete lays bricks during the use, twist behind the screw, fastener body minor diameter end struts towards expanding all around, the heliciform connecting plate is to embedding all around, owing to be helical configuration, and are not liable to disengage, therefore, can with the article fix aerated concrete lay bricks and similar light thing on, a structure is simple, the production cost is low, stationary stable is good, and is suitable for popularization and use.
Description
Technical field
The utility model belongs to technical field of fastening, is specifically related to a kind of aerated concrete brick laying fastening piece for being fixed on by object on air brick and analog thereof.
Background technique
Aerated concrete brick laying is the New Building Materials that a kind of light porous, insulation, fireproof performance are good, can follow closely, can saw, can dig and have certain shock resistance.But the fastening pieces such as common setscrew are used in shortcoming air brick existing fastening effect difference, new fastening piece is needed firmly to be arranged on air brick by object.
Model utility content
In order to solve above-mentioned problems of the prior art, the utility model object be to provide a kind of easy to use, good fixing effect for object being fixed on the aerated concrete brick laying fastening piece on air brick and analog thereof.
Described a kind of aerated concrete brick laying fastening piece, comprise fastener body, in fastener body, screw attachment holes is set, it is characterized in that described fastener body and screw attachment holes are the cylindrical structure of reducing, increase from smaller diameter end to larger diameter end diameter continuity, fastener body outer surface evenly arranges helical fastening sheet, and helical fastening sheet one end is equal with fastener body large diameter one end end face.
Described a kind of aerated concrete brick laying fastening piece, is characterized in that described helical fastening sheet is 2-6 sheet, is evenly distributed on fastener body outer wall.
Described a kind of aerated concrete brick laying fastening piece, it is characterized in that described helical fastening sheet termination is set to tip type structure, tip type structure one end is positioned at minor diameter one end, and the spacing of helical fastening sheet termination and termination, fastener body minor diameter one end is 3-5mm.
Described a kind of aerated concrete brick laying fastening piece, is characterized in that the sidewall of fastener body minor diameter one end is provided with 1-3 axial notch.
Described a kind of aerated concrete brick laying fastening piece, is characterized in that the length of axial notch is 1/2 to 2/3 of fastener body total length.
Above-mentioned a kind of aerated concrete brick laying fastening piece, comprise fastener body, in fastener body, screw attachment holes is set, described fastener body and screw attachment holes are the cylindrical structure of reducing, increase from smaller diameter end to larger diameter end diameter continuity, fastener body outer surface evenly arranges helical fastening sheet, and helical fastening sheet one end is equal with fastener body large diameter one end end face.The utility model, by adopting above-mentioned technology, obtains aerated concrete brick laying fastening piece, after being screwed into screw during use, squeeze in gas concrete building brick by this aerated concrete brick laying fastening piece, fastener body smaller diameter end expands towards surrounding and struts, and helical fastening sheet embeds to surrounding, owing to being helicoidal structure, not easily deviate from, therefore, object can be fixed on aerated concrete brick laying and similar lightweight thing thereof, its structure is simple, low cost of manufacture, stability maintenance is good, is suitable for applying.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is plan structure schematic diagram of the present utility model.
In figure: 1-screw attachment holes, 2-axial notch, 3-fastener body, 4-helical fastening sheet.
Embodiment
Below in conjunction with Figure of description, the utility model will be further described, but protection domain of the present utility model is not limited in this:
As depicted in figs. 1 and 2, a kind of aerated concrete brick laying fastening piece of the present utility model, comprise fastener body 3, screw attachment holes 1 is set in fastener body 3, for the ease of expanding and stinging tight, described fastener body 3 and screw attachment holes 1 are the cylindrical structure of reducing by the utility model, increase from smaller diameter end to larger diameter end diameter continuity, fastener body 3 outer surface evenly arranges helical fastening sheet 4, helical fastening sheet 4 one end is equal with fastener body 3 large diameter one end end face, described helical fastening sheet 4 is 2-6 sheet, be evenly distributed on fastener body 3 outer wall, after cylinder type screw is screwed into screw attachment holes 1, minor diameter one end outwards expands, revolve shape fastening sheet 4 also outwards to open simultaneously, firmly be engaged with aerated concrete brick laying, it itself is helicoidal structure, loosen when preventing the time long and exit.
As shown in the figure, described helical fastening sheet 4 termination is set to tip type structure, tip type structure one end is positioned at minor diameter one end, and the spacing of helical fastening sheet 4 termination and termination, fastener body 3 minor diameter one end is 3-5mm, be convenient to squeeze in aerated concrete brick laying, simultaneously in order to prevent fastener body 3 damaged, the utility model is provided with a 1-3 axial notch 2 on the sidewall of fastener body 3 minor diameter one end, and the length of axial notch 2 is 1/2 to 2/3 of fastener body 3 total length, not only add its operation ease, also ensure that the quality of fastener body 3 simultaneously.
