Abstract
The utility model relates to an expansion-tube fastener which comprises a tube body of an expansion tube, and a screw nail which is inserted into the tube body of the expansion tube along an axial direction. The lower part of the tube body of the expansion tube is provided with a plurality of expansion claws, and the upper part of the side wall of the tube body of the expansion tube is provided with an annular embedding slot for a plastic pad; a plastic pad is embedded in the position of the embedding slot for a plastic pad in a dismountable mode, and the upper end surface of the plastic pad and the upper end surface of the tube body of the expansion tube are in the same plane surface. When the utility model is used, when a steel wire gauze is nailed to a wall, such as a polyphenyl plate, a builder can take off an unsuitable plastic pad by hands, and a suitable plastic pad is installed instead, so the steel wire gauze can be conveniently nailed on the wall, such as the polyphenyl plate, according to design requirements; when a glass fiber net is nailed on the wall, such as the polyphenyl plate, the builder can likewise take off an unsuitable plastic pad to install a suitable plastic pad instead, so the glass fiber net can be nailed on the wall, such as the polyphenyl plate, according to design requirements. Thereby, the expansion-tube fastener of the utility model has the characteristics of convenient use, low manufacturing cost and good universality.
Description
Technical field
The utility model relates to the expand tube fastening piece that a kind of construction is used.
Background technique
In various construction, usually need to utilize earlier the expand tube fastening piece that steel wire or glass fiber mesh are followed closely on the outer surface of body of wall, and then utilize slush that steel wire or glass fiber mesh is bonding firmly.In order to ensure bonding strength, when metal lathing, usually should keep a distance that is not less than 4mm between the outer surface of designing requirement body of wall and the steel wire, and when the nail glass fiber mesh, then require the outer surface of body of wall to paste mutually each other with glass fiber mesh, for this reason, existing expand tube fastening piece needs the expand tube of band boss structure plastic mattress and not satisfy construction requirement with these two kinds of structures ability of expand tube of boss structure plastic mattress are above-mentioned, but make two kinds of structure expand tubes and just need two molds, can strengthen the cost of production of expand tube fastening piece producer thus, also can bring inconvenience to construction.
The model utility content
It is a kind of easy to use that the purpose of this utility model is to provide, and cost is low, the expand tube fastening piece that versatility is good.
The utility model expand tube fastening piece, comprise the expand tube body and be inserted in the interior screw of expand tube body vertically, have several bloated pawls in the bottom of expand tube body, the top of described expand tube tube wall has the plastic mattress embedding slot of annular, the place is embedded with plastic mattress removably at the plastic mattress embedding slot, and the upper-end surface of plastic mattress is concordant with the upper-end surface of described expand tube body.
The utility model expand tube fastening piece, the upper-end surface of wherein said plastic mattress radially are provided with at least one straightedge platform in uniform way, and the cross section of each straightedge platform is trapezoidal or semicircle or triangle or a ∩ shape of rectangle.
The utility model expand tube fastening piece, the quantity of wherein said straightedge platform are 2-6.
The utility model expand tube fastening piece, the upper-end surface of wherein said plastic mattress is provided with at least one annular boss along circumference, and the cross section of each boss is trapezoidal or semicircle or triangle or a ∩ shape of rectangle.
The utility model expand tube fastening piece, the quantity of wherein said boss are 1-3.
The utility model expand tube fastening piece, the upper-end surface of wherein said plastic mattress are provided with the round platform of a plurality of cylindrical or rings in uniform way.
The utility model expand tube fastening piece, wherein said plastic mattress is provided with a plurality of through holes, and the bottom of described screw has screw thread, and the quantity of described bloated pawl is 2-4.
The utility model expand tube fastening piece, because the top of its expand tube tube wall has the plastic mattress embedding slot of annular, the place is embedded with plastic mattress removably at the plastic mattress embedding slot, in use, if on body of wall such as the styrofoam metal lathing, the workmen can take off inappropriate plastic mattress with hand, changes the suitable plastic pad, thereby can easily steel wire be followed closely on body of wall such as styrofoam according to designing requirement.If follow closely glass fiber mesh on body of wall such as styrofoam, the same available hand of workmen takes off inappropriate plastic mattress, changes the suitable plastic pad, thereby can easily glass fiber mesh be followed closely on body of wall such as styrofoam according to designing requirement.So it is easy to use that expand tube fastening piece of the present utility model has, cost is low, the characteristics that versatility is good.
