Detailed description of the invention
Below, with reference to the accompanying drawings of a kind of embodiment of concrete frame of the present invention.In the present embodiment, the situation that the surperficial concrete frame enforcement antidetonation to being configured in vertically extending ground is strengthened is described.Fig. 1 is the plan view of the concrete frame of the enforcement antidetonation reinforcement of present embodiment, and Fig. 2 is the front view of Fig. 1, and Fig. 3 is the side view of Fig. 1.In addition, below, for convenience of description, in concrete frame, sometimes ground side is called to " front ", a side contrary with ground is called to " rear end side ".
<1. the structure > of concrete frame
As shown in FIG. 1 to 3, the concrete frame 1 of present embodiment is formed on the surface of vertically extending ground S, comprises concrete wall 2 and is embedded in its inner bar construction 3.Below, at the wall of concrete wall 2, ground side is called the back side (the second face), and a side is called surface (first surface) in contrast to this, and surface is working face.Bar construction comprises: the first reinforcing bar body 41 that is configured in the face side of concrete wall 2; Be configured in the second reinforcing bar body 42 of rear side; With the link bar 43 that they are linked.The first reinforcing bar body 41 comprises: the multiple main reinforcements 411 that extend at above-below direction; With multiple secondary reinforcing bar 412 orthogonal with it and that extend in the horizontal direction, they connect to clathrate and form the first reinforcing bar body 41.This first reinforcing bar body 41 roughly separates the mode of extending in face direction (XZ direction) on the first distance L 1 ground with the surface from concrete wall 2 and configures.Separate this first distance L 1, the region of configuration reinforcement body is not equivalent to so-called " topping ".In addition, the position that separates the first distance L 1 from the surface of concrete wall 2 is called primary importance P1(with reference to Fig. 4).
The second reinforcing bar body 42 forms similarly, comprising: the multiple main reinforcements 421 that extend at above-below direction; With multiple secondary reinforcing bar 422 orthogonal with it and that extend in the horizontal direction, their link and form the second reinforcing bar body 42 for clathrate.This second reinforcing bar body 42 roughly separates second distance L2 with the back side from concrete wall 2 and configures in the mode of face direction (XZ direction) extension.Separate this second distance L2, the region of configuration reinforcement body is not equivalent to so-called " topping " yet.In addition, the position that separates second distance L2 from the back side of concrete wall 2 is called second place P2(with reference to Fig. 4).At this, the first distance L 1 is made as same distance with second distance L2, but can appropriate change according to this distance of Construction Condition.The distance of " topping " is preferably identical with the position that the reinforcing bar bodies such as main reinforcement are set.That is to say, primary importance P1 is equivalent to the reinforcing steel bar center position of the main reinforcement 411 in concrete wall 1, and second place P2 is equivalent to the reinforcing steel bar center position of main reinforcement 421.In addition, the first reinforcing bar body 41 and the second reinforcing bar body 42 utilize multiple link bars 43 to link.The mode that link bar 43 extends with the thickness direction at concrete wall 2 is formed as bar-shaped, and the cross section of the grid of each reinforcing bar body 41,42 is connected to each other.
Further, in this concrete frame 1, in order to strengthen antidetonation, be embedded with multiple shearing reinforcing ribs 5.As shown in FIG. 1 to 3, shearing reinforcing rib 5 is formed as bar-shaped, and the mode of extending with the thickness direction at concrete wall 2 is buried underground.The position of burying underground is roughly the inside of the grid of the first reinforcing bar body 41 and the second reinforcing bar body 42.That is to say, be embedded in and the first reinforcing bar body 41 and the non-interference position of the second reinforcing bar body 42.
Fig. 4 is the enlarged drawing that represents the state of burying underground of shearing reinforcing rib.As shown in the drawing, shear reinforcing rib 5 and comprise the deformed bar on surface with the rib of regulation shape.In addition, front end is cutting sharp keen shape at 45 °.The shearing reinforcing rib 5 forming is like this inserted in the boring 21 forming at thickness direction from the surface of concrete wall 2, by being supplied to the mortar immobilization material in boring 21, is fixed in boring 21 equally.In addition, shearing reinforcing rib 5 is configured to extend between the first reinforcing bar body 41 and the second reinforcing bar body 42.That is to say, the distance T between the primary importance P1 in concrete wall 2 and second place P2 is equivalent to shear the length of reinforcing rib.Wherein, owing to forming " topping " in the front of such shearing reinforcing rib 5 and rear end side, the length of therefore shearing reinforcing rib 5 also can be shorter than illustrated.For example, shearing the length of reinforcing rib can be 6 times of its diameter.Wherein, the length D of boring 21 is the first distance L 1 and the summation of shearing the length T of reinforcing rib 5.
<2. the antidetonation of concrete frame is strengthened construction method >
Then the antidetonation that, concrete frame is described is strengthened construction method.The object is here the concrete frame 1 having arranged, and as mentioned above, is to be embedded with the first reinforcing bar body of linking by link bar 43 and the concrete frame 1 of the second reinforcing bar body 41,42.With reference to Fig. 5 and Fig. 6, the burying underground of shearing reinforcing rib 5 of strengthening for antidetonation is described below.
First, as shown in Fig. 5 (a), core drill (core drill) 6 is arranged on to the surface of concrete wall 2, holes.Wherein, the auger of holing is not particularly limited, and also can use Churn drill (hammer drill) etc.The position of holing as mentioned above, is the inside of the grid of two reinforcing bar bodies 41,42.And, as shown in Fig. 5 (b), form the boring 21 that arrives second place P2.After the formation of boring 21 finishes, make clear water in boring 21 interior circulations, 21 inner the cleaning of holing.
Then, prepare mortar cavity (mortar bag, mortar capsule) 7.This mortar cavity 7 is the structures that are accommodated with mortar powder in the bag forming at the hydrophilic material that can be infiltrated by the water such as paper, bonded fabric, and it is formed as bar-shaped.Afterwards, mortar cavity 7 is immersed in water to approximately 2～5 minutes.Thus, water enters the inside of bag, with mortar powder generation hydration reaction.The claylike mud immobilization material generating by hydration reaction starts sclerosis, through after the above-mentioned time, mortar cavity 7 is properly inserted in boring 21.As shown in Fig. 5 (c), mortar cavity 7 is formed as bar-shaped, therefore, lists and mortar cavity 7 is inserted until landfill boring 21 one along boring 21.
Then, as shown in Figure 6 (a), install and shear reinforcing rib 5 at the front end of Churn drill 8, the rearward end of impact shear reinforcing rib 5 on one side, squeezes into shearing reinforcing rib 5 in boring 21 on one side.Thus, the sharp keen leading section of shearing reinforcing rib 5 destroys the cavity (bag, capsule) 7 in boring 21 on one side, enters boring 21 on one side.Like this, as shown in Figure 6 (b), shearing reinforcing rib 5 is driven into until its front end arrives the inner end portion (second place P2) of boring 21.In this process, the claylike mortar immobilization material of deviating from from destroyed cavity 7 spreads all over the whole outer peripheral face of shearing reinforcing rib 5 in boring 21, and by shearing advancing of reinforcing rib 5, mortar immobilization material is stirred in boring 21.Thus, mortar immobilization material is filled in to be sheared between the outer peripheral face of reinforcing rib 5 and the internal face of boring 21, is fixed in boring 21 thereby shear reinforcing rib 5.
The rearward end that is fixed on like this shearing reinforcing rib 5 in boring 21 is positioned at primary importance P1, and the region between this rearward end and concrete wall 2 becomes " topping ", and this area filling in boring 21 has mortar immobilization material.Afterwards, from the 21 remaining mortar immobilization materials that overflow of holing by processing and remove by plasterer.The in the situation that of mortar immobilization material deficiency, again mortar immobilization material is filled in addition in boring 21.Like this, as shown in Figure 6 (c), complete construction.
<3. feature >
As mentioned above, according to present embodiment, the shearing reinforcing rib 5 that is embedded in the inside of concrete wall 2 arranges from a predetermined distance from two walls of concrete wall 2.That is to say, between the shearing both ends of reinforcing rib 5 and the wall of concrete wall 2, be provided with so-called " topping " of not burying reinforcing bar underground.Thereby, can prevent that concrete wall 1 entirety from becoming rigid structure.Its result, can not improve the bending strength of concrete frame 1, and only improve shear strength.Therefore, when for example occur more than design grade earthquake time, as shown in Figure 7, can make concrete frame 1 first bend and destroy and shear failure do not occur.By this bending failure, can absorb seismic energy, can improve the final anti-seismic performance of concrete frame 1 entirety.That is to say, can make bending failure first occur and prevent shear failure, therefore, can avoid the dropping of weight, avalanche.So, for the powerful earthquake that exceedes design, also can avoid the avalanche of concrete frame 1 entirety, can maintain the performance to a certain degree as concrete frame 1.
<4. variation >
An embodiment of the invention have more than been described, but the present invention is not limited to above-mentioned embodiment, only otherwise depart from its aim, just can carries out various changes.For example, shear the structure of reinforcing rib 5, be not limited to said structure, also can carry out various changes.For example, as shown in Figure 8 (a), also can use front end to be formed as cone shape shearing reinforcing rib 5.In addition, as shown in Figure 8 (b) shows, also can use the shearing reinforcing rib 5 that is formed with male thread on surface.That is to say, front end shape or the surperficial shape of shearing reinforcing rib 5 are not subject to particular restriction.
In addition, as long as immobilization material can be fixed in boring 21 shearing reinforcing rib 5, be not just subject to particular restriction, in addition, can not use the immobilization material of cavity (bag, capsule) dress yet.
In the above-described embodiment, will shear reinforcing rib 5 by Churn drill 8 and insert in boring, but this point is not subject to particular restriction yet.As other example, for example, also can use fixture as shown in Figure 9.As shown in Fig. 9 (a), this fixture 9 has the main part 91 of the tubular that is formed with through hole.In main part 91, be provided with the major diameter portion 92 larger than the diameter of boring 21 at the first end relative with boring 21.And, in through hole, can insert and shear reinforcing rib 5 from first end.
In addition, in the through hole of main part 91, inserted columned impact part 93 in the mode that can advance and retreat.Impact part 93 is outstanding from the second end of the main part 91 of a side contrary with first end.And, be provided with the retainer 94 of the ring-type larger than through hole at this ledge.In addition, at the outer peripheral face of impact part 93, between retainer 94 and the second end, reel spring 95 is installed.Thus, impact part 93 antagonistic springs 95 are also pushed into, and in the time that push-on force is removed, return to initial position.In addition, in the time that impact part 93 is pushed into, its leading section is outstanding from first end, and as shown in Fig. 9 (d), its outstanding length is identical with the first above-mentioned distance L 1.
Then, the fixture 9 that utilizes this structure is described, the method for constructing to shearing reinforcing rib 5.First,, as shown in Fig. 9 (a), a part of shearing reinforcing rib 5 is inserted in boring 21.Afterwards, as shown in Figure 9 (b), at the main part 91 of rearward end sectional fixture 9 of shearing reinforcing rib 5.Now, the rearward end of shearing reinforcing rib 5 is inserted into through hole from first end.Under this state, as shown in Figure 9 (c), the rearward end of impact part 93 and Churn drill 8 are linked, or utilize hand hammer etc. to beat.Thus, the rear end side of impact part 93 impact shear reinforcing ribs 5, is passed to holing in 21.Now, at main part 91, owing to being provided with major diameter portion 92, therefore, main part 91 does not enter in boring 21, and in the state of the surperficial butt of concrete wall 2.
Impact part 93 antagonistic springs 95 are also pushed into, and make to shear reinforcing rib 5 and pass to holing in 21, and now, as shown in Fig. 9 (d), the leading section of impact part 93 is outstanding from main part 91, arrives the primary importance P1 in concrete frame 1.But, be provided with retainer 94 at impact part 93, by itself and the second end butt, impact part 93 can not move to the more forward distolateral position than primary importance P1.Therefore the mode that the shearing reinforcing rib 5, being pushed by impact part 93 is positioned at primary importance P1 with rearward end is pushed into.Thereby, can in the rear end side of shearing reinforcing rib 5, " topping " be reliably set.
