Abstract
The utility model provides an it is embedded from merit silk expansion bolts relates to the mechanical engineering field. An it is embedded from merit silk expansion bolts comprises integral type button head internal thread expansion bolts and embedded the nail from merit silk wedge. Integral type button head internal thread expansion bolts's circular head can guarantee that anti rust coating thickness is even when the spraying anti -corrosive paint, and embedded do not have the exterior structure after the complete screw in expansion bolts of merit silk wedge nail makes the construction, effectively reduced the possibility that it is embedded from merit silk expansion bolts is corroded, has lengthened life, has improved the engineering quality, adopts embeddedly from merit silk wedge nail, and expansion bolts and the extrusion force of holing between the inner wall are easily controlled to the engineering quality has been guaranteed.
Description
Technical field
This utility model relates to mechanical engineering field.
Background technology
Use the reinforcing of the engineering structure such as Bridges in Our Country, building construction more and paste the technology such as steel plate method.As it is shown in figure 1, be
Guarantee that existing reinforced concrete and steel plate participate in stress jointly, except structure glue between reinforced concrete interface and strengthening steel slab
Outward, in addition it is also necessary to according to certain spacing, expansion bolt is set, prevent strengthening steel slab, structure glue and existing reinforced concrete three it
Between occur failure by shear.
The expansion bolt that the most total technology uses constructs as shown in Figure 2.This type of expansion bolt is in practical engineering application
There are the following problems: when 1, manually tightening nut, it is difficult to ensures the uniformity of screw rod pulling force；2, during rust prevention by applying liquid material paint, hexagonal
Nut edges and corners rust preventive painting layer thickness is difficult to reach the technology requirement of design and construction technical standard order；3, unnecessary lead screw
Not only hinder attractive in appearance, and the modification of lead screw also results in the technical problem such as wage quality and reduction in service life, lead screw
The structure being corroded at first often.
Summary of the invention
For solving above-mentioned technical barrier, this utility model is given a kind of embedded from merit silk expansion bolt.Embedded from merit
Silk expansion bolt by integral type round end internal thread expansive bolt and embedded from merit silk chock nail form；
Integral type round end internal thread expansive bolt has four sections of different hollow structures of diameter, is the premise of L at total length
Under be divided into round end length L1, female thread cavity length L2, wedge length L3, expansion structure length L4；
The round end overall diameter of integral type round end internal thread expansive bolt is D1, the circle of integral type round end internal thread expansive bolt
Head diameter of bore is D2；
The female thread cavity overall diameter of integral type round end internal thread expansive bolt is D3, integral type round end female thread expanding screw
The female thread cavity diameter of bore of bolt is D4；
The circular configuration that cross section is pintongs type of the expansion structure of integral type round end internal thread expansive bolt, can pass through wedge
Son makes the circular configuration of pintongs type strut, and the circular configuration overall diameter of pintongs type is D3, and the circular configuration interior diameter of pintongs type is
D5；
The embedded a diameter of D2 of dome from merit silk chock nail, agrees with in the round end of integral type round end internal thread expansive bolt
Bore dia D2；
The embedded dome from merit silk chock nail has cross recess structure；
By the embedded length from merit silk chock nail of regulation, control a kind of embedded in merit silk expansion bolt and boring
Extruding force between wall.
Beneficial effect
The rounded nose of integral type round end internal thread expansive bolt can ensure that the antirust coat thickness when rust prevention by applying liquid material paint
Uniformly, embedded being completely screwed into after expansion bolt makes construction from merit silk chock nail does not has external structure, effectively reduces embedded
The probability that formula is corroded from merit silk expansion bolt, extends service life, improves construction quality, uses embedded from merit silk
Chock is followed closely, and the extruding force between expansion bolt and drill hole inner wall is easily controllable, thus ensure that construction quality.

The female thread cavity diameter of bore of bolt A is D4；
The circular configuration that cross section is pintongs type of the expansion structure of integral type round end internal thread expansive bolt A, can pass through
Chock makes the circular configuration of pintongs type strut, and the circular configuration overall diameter of pintongs type is D3, the circular configuration interior diameter of pintongs type
For D5；
The embedded a diameter of D2 of dome from merit silk chock nail B, agrees with the round end of integral type round end internal thread expansive bolt A
Diameter of bore D2；
The embedded dome from merit silk chock nail B has cross recess structure；
By the embedded length from merit silk chock nail B of regulation, control a kind of embedded from merit silk expansion bolt and boring
Extruding force between inwall.
A kind of embedded use step from merit silk expansion bolt of example is as follows:
1) boring (diameter=D+2mm of boring)；
2) impurity such as the dust in hole are remained in device cleanings such as vacuum cleaners；
3) first integral type round end internal thread expansive bolt A is inserted in boring, be inserted into embedded from merit silk chock
Nail B；
4) B is followed closely with screw gun screw-in is embedded from merit silk chock, until embedded chock nail is completely embedded into integral type round end
Position in internal thread expansive bolt A cap.
