Abstract
The utility model discloses a structure of a deformation gasket; the deformation gasket is arranged in an inner aperture space of an inwards concave hole at the bottom of a bolt in an inwards concave mounting hole mounted on a cement foundation after knocking deformation, so that the stability and reliability of the fixed bolt mounted on the cement foundation can be improved, and the mounted bolt to hardly fall off, and has the characteristic of convenient implementation.
Description
Technical field
The utility model is set bolt construction tool and parts, belongs to the realm of building construction.
Background technology
On buildings such as concrete pedestal, implement in the job practices of set bolt at present, be mostly after the concrete pedestal construction is finished, adopt expand tube bolt mounting means to implement the construction of set bolt, in present expand tube bolt installation, what adopt is the straight hole mounting means, promptly on concrete pedestal, get out a straight hole shape installing hole that inside and outside bore is identical, the bottom tapered slope of inserting the bolt of expand tube in the middle of expand tube of installing hole outwards struts, be pressed on the installing hole hole wall on the concrete pedestal, realize the fixing on concrete pedestal of the bolt in the middle of the expand tube by consequent frictional force, but because this installing hole is the identical straight hole of inside and outside bore, and because the limited aperture of this straight hole, the expand tube deformability is restricted, therefore have only the frictional force between expand tube deformation part and the installing hole hole wall to provide firm guarantee for set bolt, therefore its reliability of fixation is not high, having under the external force condition, especially bolt is subjected under the situation of axial tension and continuation vibration bolt taking place easily and drops, this need be avoided in actual applications, therefore, need do necessary improvement to construct related tool and parts of set bolt, to guarantee to be fixed on the reliability of bolt when using on the concrete pedestal.
Summary of the invention
In view of the foregoing, the purpose of this utility model is to provide a kind of deformed gasket, makes when installing and fixing bolt on concrete pedestal, can either be convenient to implement, and can guarantee that also the set bolt of being installed is reliable and stable in application, the difficult characteristics that come off.
For achieving the above object, the utility model is introduced a kind of deformed gasket, it is characterized in that deformed gasket is straight tubular before not knocking deformation, its length is less than the degree of depth of the boring of being installed, this straight tubular deformed gasket at one end is trapezoidal faces, this straight tubular deformed gasket is at other end internally oblique face, in the cylindrical outer wall of straight tubular deformed gasket along a plurality of pre-slottings seams are arranged on the axis direction, the end that fluting is sewn on straight tubular deformed gasket internally oblique face reaches the end, makes adjacent wall sheet not be connected at an end of internally oblique face.
Operating principle of the present utility model is: the straight hole shape installing hole that gets out on the concrete pedestal is carried out adopting this convex to bore when reaming processing is processed into the convex hole, when installing and fixing bolt, bolt is inwardly inserted in the convex hole until being enclosed within a plurality of deformed gaskets on the shank of bolt one by one behind the bottom and using sleeve and instrument such as hammer is knocked in the bolt bottom with this deformed gasket along shank of bolt with bolt head, the internal diameter of the deformed gasket of knocking in is greater than the shank of bolt external diameter and less than the bolt head external diameter, the deformed gasket of knocking in is in after knocking deformation in the internal orifice dimension space in convex hole in the bolt bottom again, and the external diameter of the deformed gasket after the deformation is greater than the outer aperture and the bolt head external diameter in convex hole, like this, just formed the restriction that bolt head is subjected to deformed gasket, and deformed gasket is subjected to the restriction in the outer aperture in convex hole, and under the filling of adhesive and bonding effect, give further fixing, when bolt is subjected to axial external broach, pass through bolt head, deformed gasket, the restriction in adhesive and outer aperture is transmitted to this pulling force on the concrete pedestal, has so just improved the reliability of this bolt.
Description of drawings
Fig. 1 is the deformed gasket structure chart of the utility model one embodiment.
The specific embodiment
Below be that example illustrates embodiment of the present utility model with the accompanying drawing:
Fig. 1 is the convex drill structure chart of the deformed gasket of the utility model one embodiment; Wherein: deformed gasket is straight tubular before not knocking distortion, the degree of depth in the convex hole that its length is made during less than erection bolt, this straight tubular deformed gasket cross section at one end is trapezoidal faces, see that the cross section shown in 1 among Fig. 1 is processed into an end of trapezoidal shape, this straight tubular deformed gasket is at the cross section of other end internally oblique face, see among Fig. 1 shown in 2 the cross section be processed in an end of inclined plane shape, in the cylindrical outer wall of straight tubular deformed gasket along a plurality of pre-slottings seams are arranged on the axis direction, see shown in 3 among Fig. 1, the end that fluting is sewn on straight tubular deformed gasket internally oblique face 2 reaches the end, makes the adjacent wall sheet not be connected at an end of internally oblique face.
Can produce deformed gasket of the present utility model according to said structure.
The utility model can also be to be processed into arc surface in this straight tubular deformed gasket cross section at one end, so also can reach the purpose of this utility model, and can be so that in processing with more convenient when producing this straight tubular deformed gasket.
Deformed gasket in the utility model can also be that deformed gasket is the hollow metal annulus before not knocking distortion, and have a plurality of wedge shape mouths in this hollow metal annulus outer rim, so also can reach the purpose of this utility model, and can be so that more convenient when processing and producing this open circles annular deformed gasket.
The utility model also is used in the construction occasion that needs set bolt on the other materials except that the cement basis, and this makes application of the present utility model more extensive.
The utility model has been introduced a kind of structure of deformed gasket, has to make when installing and fixing bolt on concrete pedestal, can either be convenient to implement, and also can guarantee the reliable and stable characteristics of set bolt in application of being installed.
Claims (2)
