Description
Technical field
This utility model relates to a kind of Rebar bonding device, particularly relates to a kind of screw-type Rebar bonding device.
Background technology
The flow process that general bar planting applies, namely so-called chemical formula bar planting, mainly first with boring bar tool at the bar planting precalculated position of the concrete structure brill an appropriate number of screw of tapping, recycling steel brush (or jet gun) stretches into the impurity removing in screw in screw, loads medicament in screw. The medicament that current bar planting uses is mainly composed of at the bottom of epoxy resin or cement based, with after hardening for reinforcing steel implant.
But; above-mentioned traditional bar planting method is except in removing screw, the complex steps of impurity is taken a lot of work; if and be applied in the weather of hot humid; the concrete of sea sand and bad etc. the factor of construction quality is mixed plus using; the especially easy corrosion of reinforced concrete construction thing; when the chloride ion of inside concrete rebar surface exceedes certain amount; bar planting medicament can produce creep; when creep reaches to a certain degree; the protectiveness passivating film of rebar surface starts to destroy; then reinforcing bar starts corrosion and expands, and causes concrete layer to chap, avalanche.
Consulting Fig. 1, be an existing planting reinforced bar into concrete device 1, it is adaptable to a concrete structure 10, this concrete structure 10 is equipped with a positioning screw hole 101 in the position arranging this planting reinforced bar into concrete device 1. This planting reinforced bar into concrete device 1 comprises crab-bolt 11, reinforcing bar 12 and a joint unit 13. This crab-bolt 11 includes a screw head portion 111, and is connected with this screw head portion 111 and outer surface is formed around with the threaded shank 112 of an external screw teeth 110 and a screw channel portion 113 extended towards this threaded shank 112 by this screw head portion 111. The threaded shank 112 of this crab-bolt 11 is by this external screw teeth 110, is embedded in this concrete structure 10 with positioning screw hole 101 bolt of this concrete structure 10, and the screw head portion 111 of this crab-bolt 11 then protrudes from the outer surface of this concrete structure 10. This joint unit 13 is located at this reinforcing bar 12 at least one end, and this joint unit 13 includes a spiro portion 131, and this reinforcing bar 12 is screw channel portion 113 bolt by the spiro portion 131 of this joint unit 13 with this crab-bolt 11.
But, owing to this planting reinforced bar into concrete device 1 must fix this crab-bolt 11 in advance, just by the implantation that locks by the spiro portion 131 of this combining unit 13 of this reinforcing bar 12, the installation steps that need to carry out still dislike loaded down with trivial details. Further, since this planting reinforced bar into concrete device 1 comprises multiple element separated from one another, therefore it is difficult to adopt single product line once to make, thus limits manufacture efficiency.Moreover, this crab-bolt 11 must also be processed and this screw channel portion 113 of molding by processing procedure, and coordinate this spiro portion 131 in this screw channel portion 113, also need to be additionally carried out the processing operation of screw thread, therefore cause the shortcoming that processing cost is higher.
Summary of the invention
The purpose of this utility model is in that to provide one not use chemical agent and the screw-type Rebar bonding device that implantation process is simplified.
This utility model screw-type Rebar bonding device, comprises the screw head an of reinforcing bar, the one end being integrally connected to this reinforcing bar and the screw rod of the other end being integrally connected to this reinforcing bar.
The material that this reinforcing bar is identical with building bar employing, for being connected in the way of binding, welding etc. with building bar.
This screw rod includes a body of rod, and the screw thread on this body of rod is located at by a helical ring. When carrying out bar planting operation, it is first be drilled with a boring at an xoncrete structure, then utilize this screw rod to carry out brill attack from this screw head force, any chemical agent need not be used, also the step of impurity that do not need to be purged in this boring especially, this screw-type Rebar bonding device can be made really to implant this xoncrete structure, quickly and complete bar planting operation with simplifying.
The purpose of this utility model and solve its technical problem and also can be applied to the following technical measures to achieve further.
It is preferred that aforementioned threads formula Rebar bonding device, wherein this screw thread be from this body of rod away from one end of this reinforcing bar towards this reinforcing bar spiral extension.
It is preferred that aforementioned threads formula Rebar bonding device, wherein this screw thread has a first edge face and a second edge face pressing from both sides an angle with this first edge face, and this angle is between 30 degree to 60 degree, and comprises endpoint value.
It is preferred that aforementioned threads formula Rebar bonding device, wherein this screw head is through cure process.
It is preferred that aforementioned threads formula Rebar bonding device, wherein at least some of through cure process from extension away from one end of this reinforcing bar of this screw flight.
Beneficial effect of the present utility model is in that: this screw-type Rebar bonding device need not adopt any chemical agent, also do not need to remove the impurity in this prebored hole, and owing to this screw-type Rebar bonding device is formed in one, therefore can be exerted a force by this screw head, utilize this screw rod directly to bore and attack this xoncrete structure, complete bar planting operation with step that is quick and that simplify.
