Description
Technical field
The present invention relates to a kind of locking device of lattice shape reinforcement, especially a kind of locking device that locks lattice shape reinforcement with uniform thickness securely, this device is arranged in the various concrete structures, and be embedded in securely in the joint filler between lattice shape reinforcement and the concrete surface, thereby the adhesion strength between the enhancing joint filler, and a kind of method of using this device to strengthen concrete structure.
Background technology
For improving the intensity of various concrete structures, normally in concrete, bury concrete reinforcement underground such as band shape reinforcing bar, rib shape reinforcing bar and spirality reinforcing bar.Though these reinforcing steel bars have cheapness and have the advantage of suitable intensity, yet, owing to making it, the reason of its weight is not easy carrying and construction, and, the corrosion of steel bar in concrete needs the anti-corrosion measure owing to can causing concrete spalling, and when arranging reinforcing bar in length and breadth, can produce sizable thickness difference.
For remedying the defective of these reinforcing bar reinforcements, Korea S 86-6838 patent application has disclosed a kind of fiber lattice shape reinforcement.In the prior art, lattice shape reinforcement is locked on the concrete surface locking device 1 as shown in Figures 1 and 2.
This locking device 1 is made up of bolt 2, nut 3, packing ring 4 and center (tensioner) bar 6, but there are some defectives in this structure, for example nut 3 must be tightened, reinforcement 5 can't secure lock and reinforcement easily come off etc.In addition, when on concrete surface, holing, can can't accurately locate, also be attended by the danger that damages reinforcement simultaneously because of vibration for forming hole that set bolt uses.
Summary of the invention
Therefore, the object of the present invention is to provide a kind of locking device of lattice shape reinforcement, this device uses rivet shape steady pin, only by hammering (tensioner) lattice shape reinforcement accurately and securely is locked on the concrete surface.
Another object of the present invention is to provide a kind of method that strengthens concrete structure securely, it uses rivet shape steady pin that lattice shape reinforcement is locked in the concrete structure exactly.
According to an aspect of the present invention, the locking device of lattice shape reinforcement comprises a fixed head and a rivet shape steady pin, along being formed with microscler notch on the thickness part of fixed head, be used to insert reinforcement, and steady pin top is formed with a substrate shape head, and wherein the heart is protruding with a hammering (tensioner) bar.In addition, fixed head is made by cement mortar, stainless steel, plated metal, plastics, FRP (glass fiber reinforced plastic) etc., and steady pin is made by the material that stainless steel or plated metal etc. can corrosions.
According to a further aspect in the invention, strengthen the method for concrete surface, may further comprise the steps: remove laitance and dust and water flushing on the concrete surface by using the locking device that constitutes by fixed head and rivet shape steady pin; Lattice shape reinforcement is installed on concrete surface; After fixed head being attached to the bight of reinforcement, pass the steady pin patchhole on the fixed head and on concrete surface, hole with rig; Insert steady pin by steady pin patchhole on the fixed head, hammering (tensioner) center hammering (tensioner) bar, thus make the lower expansion of steady pin that hammering (tensioner) bar is locked on the concrete surface with fixed head; Smearing adhesive aid on the concrete surface with the stickiness between increase concrete surface and joint filler, and; Fill joint filler to the upper face that surpasses locking device.

The invention preferred forms
With reference to the accompanying drawings, to a preferred embodiment of the present invention will be described in detail.
Fig. 3 and Fig. 4 are according to the exploded perspective illustration of locking device of the present invention and user mode figure thereof.Locking device 10 is made of fixed head 11 and steady pin 12, fixed head 11 can adopt quadrangle, pentagon or circular shape, the notch 13 that is used for inserting for reinforcement is microscler, and is formed on the thickness part of fixed head, so that reinforcement can insert wherein.In addition, be formed with the hole 15 that is used to insert steady pin at the center of fixed head 11,15 top is formed with a head arrangement portion 17 in the hole, is used for settling reliably the substrate shape head 16 of steady pin 12.Fixed head 11 adopt not can corrosion material make preferably cement mortar, stainless steel, plated metal, plastics, FRP etc.Simultaneously, different with the bolt/nut form of available technology adopting, steady pin 12 adopts the rivet form.Steady pin 12 is made of shank 18, substrate shape head 16 and center hammering (tensioner) bar 19, when in shank 18 patchholes 15 of steady pin 12, with hammer (or riveting gun) hammering center hammering (tensioner) bar 19, the substrate shape head 16 of steady pin just is fixed in the head arrangement portion 17 of fixed head 11, can expand and be locked in (referring to Fig. 5) on the concrete surface 20 in the bottom of shank 18.Certainly, on concrete surface 20 the hole 15 by fixed head 11 bored the hole in advance.Steady pin 12 is made by the material of not corrosions such as stainless steel or plated metal.
Referring now to Fig. 5, will carry out detailed progressively explanation to the method for using locking device of the present invention to strengthen lattice shape reinforcement, wherein locking device is locked in the concrete structure.
At first, with high-pressure water spraying gun all impurity such as mortar skin on the concrete surface 20 and dust are washed.Then, then reinforcement is inserted in the notch 13 on the fixed head 11 with the lattice shape reinforcement of holding tightly on cleaning concrete face 20.Afterwards, after fixed head being placed desire boring position, pass the hole 15 on the fixed head 11 with the electric drill (not shown) again and on concrete surface, hole.With steady pin 12 15 insertions from the hole, with center hammering (tensioner) bar 19 on hammer (or riveting gun) hammering (tensioner) steady pin top, shank 18 expands steady pin is locked on the concrete surface with locking device 10.Every square metre of locking device 10 of installing at least more than 6 preferably.After installing locking device, adhesive aid 30 is spread upon on the concrete surface, to increase the caking property between concrete and the joint filler 40, then, joint filler 40 is filled to upper face above steady pin 12 after, obtain final placement-face.Thus, the step according to the present invention makes concrete surface clean and tidy and obtain firm enhancing.
Locking device according to use rivet shape steady pin of the present invention, only must can fulfil assignment rapidly by the hammering center-pole, thereby efficient is high, because the lattice shape portion of reinforcement is locked securely, so can not produce the phenomenon that reinforcement comes off from fixed head, again owing to be to pass locking device to hole,, and can prevent damage because of drilling operation plaid matching shape reinforcement material so bore position is accurate.
