Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a frame member for constituting a concrete frame formed on a slope, and in particular, supported by a reinforcing bar or the like which is one of the structural members of the frame, these reinforcing bars. It is related with the frame member suitable for making a strong legal frame etc. by spraying and attaching mortar, concrete, etc. with these.
[0002]
[Prior art]
For example, the slopes that can be used on the roadside or on the site of creation should be prevented by some means, because if the ground or bedrock is left bare, a phenomenon such as collapse will occur. Slope protection is performed by spraying mortar or concrete or by vegetation, but in any case, it is generally performed by forming a so-called legal frame on the slope.
[0003]
The frame is a so-called “foundation” for protecting the slope. For example, as shown in FIG. 4 or FIG. It is made to ensure the fixing at. The slope is protected by spraying mortar, concrete, or soil into the grid-like frame.
[0004]
The above-mentioned frame is generally formed by assembling a mold containing reinforcing bars on the slope and spraying mortar, concrete or the like on the mold. However, the slope is also an inclined surface, and in some cases it is in a mountainous area where large machines are difficult to enter. On top of that, assembling the above-mentioned formwork is a very labor-intensive work. ing.
[0005]
For this reason, for example, in Japanese Patent Application Laid-Open No. 8-20957 or Japanese Patent Application Laid-Open No. 8-296233, “a method for constructing a lattice frame using a coil for a legal frame and a coil for a legal frame” A construction method and a coil reinforcement for forming a method frame have been proposed. As shown in FIG. 7 or FIG. 8, the “coil” used in the techniques described in these publications is not only able to secure a holding portion of the spray material to a certain extent but also a continuous one. Therefore, it is thought that the construction is easy.
[0006]
However, the “coil” proposed in Japanese Patent Laid-Open Nos. 8-20957 and 8-296233 is literally continuous in a coil shape and has a very soft flexibility. Therefore, unless each part is fixed to a reinforcing bar or the like, it can be considered that the pressure at the time of spraying the spray material so as to cover the coil cannot be sufficiently tolerated. If it does so, the operation | work which fixes each part to a reinforcing bar etc. will become serious, and it is thought that this "coil" has worsened workability.
[0007]
Further, as shown in FIG. 7 or FIG. 8, the “coil” proposed in the above-mentioned Japanese Patent Application Laid-Open Nos. 8-20957 and 8-296233 has a linear portion in contact with the slope. Therefore, when the slope is uneven (it is normal that there is unevenness), the coil does not sufficiently touch the slope, and a space is created between the completed slope and the slope. It is also considered that so-called “non-land (lift)” is likely to occur.
[0008]
In addition, the “coil” proposed in the above-mentioned JP-A-8-20957 and JP-A-8-296233 is bulky except when it is packed or transported. It is thought that it is difficult to store and transport. In addition, if it is a continuous type of “coil”, it can be constructed in a dense state, but it cannot be properly dispersed, and the construction position cannot be freely determined, which is very inconvenient in construction. It is thought to be a thing.
[0009]
Therefore, the inventor of the present invention has a simple structure and can sufficiently withstand the pressure at the time of spraying work, and further improve its workability and reduce the cost. The present invention has been completed as a result of extensive research on how to achieve this.
[0010]
[Problems to be solved by the invention]

[0014]
[Means for Solving the Problems]
In order to solve the above problems, first, the means taken by the invention according to claim 1 will be described with reference numerals used in the description of the embodiments described later.
“A frame member 10 for a concrete frame 100 formed on the slope 200 for its protection,
The frame member 10 is positioned so as to intersect with the bottom member 11 to be disposed on the upper side of the slope 200 without contacting the bottom member 11, and is curved or substantially the same as the top surface outline of the slope frame 100. A closed curve-shaped member having a bent top member 12 and a continuous member 13 that is arranged on the upper side of the slope 200 with both ends of the top member 12 and the bottom member 11 being continuous. Formed into
At least one of the bottom member 11 and the top member 12 is formed with at least one engagement recess 14 with which the reinforcing bar 22 constituting the normal frame 100 is engaged.
It is.
[0015]
That is, as shown in FIGS. 4 and 5, the frame member 10 according to claim 1 is disposed between the intersections of the reinforcing bars 22 arranged in a lattice shape and fixed by the anchors 23. The arrangement is as shown in FIG. 1 and FIG. In other words, as shown in FIG. 1, the frame member 10 is first arranged in a state where the bottom member 11 obliquely intersects each reinforcing bar 22 on the slope 200, and at both ends of the bottom member 11, 2 A continuous member 13 of the book is arranged in parallel with each reinforcing bar 22. Then, the end of the top member 12 continues to the other end of each continuous member 13, and this top member 12 is substantially the same as the top surface of the frame 100 as shown in FIG. 2. Therefore, the bottom member 11 is positioned so as to intersect without contacting the bottom member 11.
[0016]
In addition, as shown in FIGS. 1 and 2, the frame member 10 has an engagement recess 14 in which a reinforcing bar 22 constituting the normal frame 100 is engaged with at least one of the bottom member 11 and the top member 12. Therefore, the frame member 10 can be fixed to the reinforcing bars 22 only by engaging the reinforcing bars 22 with the engaging recesses 14. Since this engagement recess 14 is formed by bending or bending a wire, as illustrated in the embodiments described later, the engagement of each reinforcing bar 22 with this is easily performed from the outside of the frame member 10. It can be done. In addition, about each frame member 10 installed on the slope 200, you may make it fix to the slope 200 more firmly by raising an anchor pin in the center part.
[0017]
As described above, when the frame member 10 according to the first aspect is installed on the slope 200, the bottom member 11 inclined obliquely with respect to the reinforcing bar 22, and both ends of the bottom member 11. The two continuous members 13 that are continuous are arranged on the slope 200, and the frame member 10 is generally in close contact with the slope 200 as a whole. Moreover, since the top member 12 of the frame member 10 protrudes on the slope 200 along the outer shape of the method frame 100 to be completed, the frame member 10 has a substantially bowl shape together with the bottom member 11 and the continuous member 13. Thus, a portion where the spraying material 30 can be attached and held satisfactorily is formed.
[0018]
Therefore, when the spraying operation of spraying the spraying material 30 such as ready-mixed concrete or mortar toward the frame member 10 or the like is performed, the frame member 10 is arranged in a very stable state on the slope 200. It does not move due to the spraying pressure, or does not come off from each reinforcing bar 22, and the workability is very good. Further, since the frame member 10 is generally in close contact with the slope 200 as a whole, a “non-land” portion is formed between the completed slope 100 and the slope 200. I do not.
[0019]
The frame member 10 according to the first aspect has the configuration and shape as described above. Therefore, as shown in FIG. It can be summarized as. Therefore, not only the packaging and storage after the frame member 10 is manufactured, but also the transportation to the construction site is very efficient. The workability is excellent.
[0020]
In particular, since the frame member 10 is independent from the conventional “coil” shape shown in FIG. 7 or 8, the installation position can be freely selected. For example, it can be arranged avoiding the slope 200 having large unevenness, and its workability is very good. That is, normally, about two of the frame members 10 are arranged between the intersections of the modulus frame 100. However, it is possible to freely make the number of the frame members 10 one or three.
[0021]
Moreover, in order to solve the said subject, the means which the invention which concerns on Claim 2 took about the frame member 10 which concerns on the said Claim 1,
“By curving or bending the center of the bottom member 11 and the continuous member 13 respectively upward, the continuous portion of the bottom member 11 and the continuous member 13 becomes the leg 15 and abuts on the slope 200. What I did "
It is.
[0022]
That is, in the frame member 10 of this second aspect, the continuous portion of the bottom member 11 and the continuous member 13 is positively formed as the leg portion 15, and for this purpose, the center of the bottom member 11 and the continuous member 13 is formed at the center. These are respectively curved or bent upward. In other words, the frame member 10 is installed on the lath net 21 when the lath net 21 is stretched on the sloped slope 200 as shown in FIGS. 4 and 5. Is. In this case, the first leg portion 15a, the second leg portion 15b, the third leg portion 15c, and the fourth leg portion 15d that are clearly shown in FIGS. The frame member 10 protrudes on the slope 200 from the mesh, and even if there is irregularities on the slope 200 and the lath net 21 itself floats on the slope 200, the frame member 10 is on the slope 200. It will be arranged in a close contact state.
[0023]
Therefore, the frame member 10 of claim 2 can exhibit the same effect as that of claim 1 above, and of course, even if the lath net 21 is present, the floating with respect to the upper surface of the slope 200 is prevented. Therefore, it is possible to reliably prevent unevenness of the slope 100 with respect to the slope 200. On the contrary, when the lath net 21 is in close contact with the slope 200, it is difficult to attach the spray material 30 to the lath net 21, but the frame member 10 according to claim 2 Since the one leg portion 15a, the second leg portion 15b, the third leg portion 15c, and the fourth leg portion 15d can be put in the mesh of the lath net 21, as shown in FIG. It is possible to pull up to a predetermined position on the slope 200.
[0024]
And in order to solve the said subject, the means which the invention which concerns on Claim 3 took about the frame member 10 which concerns on the said Claim 1 or Claim 2,
“The frame member 10 is formed by bending or bending a single wire”
It is.
[0025]
That is, the frame member 10 according to the third aspect is formed integrally by bending or bending a single wire made of iron, which makes the manufacture very It is cheap and easy to do. Note that it does not matter where the bent or curved ends are located on the frame member 10, but the ends of the wires are connected to each other whether they are welded or tied together with a binding wire. Needless to say, there is something to be done.
[0026]
DETAILED DESCRIPTION OF THE INVENTION
Next, the invention according to each of the claims will be described with respect to the frame member 10 that is the embodiment shown in the drawings. The frame member 10 of this embodiment substantially includes the invention of each of the claims. Therefore, in the following, description will be made focusing on the frame member 10 of this embodiment.
[0027]
FIG. 1 is a perspective view showing a state in which one of the frame members 10 according to the present invention is installed around two upper and lower reinforcing bars 22, and this frame member 10 is shown in FIGS. 1 to 3. As described above, the bottom member 11 to be disposed on the upper side of the slope 200 is positioned so as to intersect without contacting the bottom member 11 and is curved or bent in substantially the same manner as the top surface of the slope frame 100. The top member 12 and the continuous member 13 which is arranged on the upper side of the slope 200 with both ends of the top member 12 and the bottom member 11 being continuous are formed. The member 10 is formed in a closed curve by bending or bending a single wire made of, for example, iron wire.
[0028]
Of course, the frame member 10 is formed so that both ends of a single wire are integrated by welding or bundling by a binding wire. Note that the bottom member 11, the top member 12, and the two continuous members 13 that connect these end portions to each other are each formed by a wire rod, and these end portions are welded or bound by a binding wire. It may be formed as a single piece and does not necessarily have to be composed of a single continuous wire.
[0029]
Further, as shown in FIG. 2, the frame member 10 is also attached to the reinforcing bar 22 for constituting the modulus frame 100, so that at least one of the bottom member 11 and the top member 12 is used. At least one engagement recess 14 with which the reinforcing bar 22 constituting the method frame 100 is engaged is formed. The engagement recess 14 is formed by positioning in advance according to the number and position of the reinforcing bars 22 constituting the method frame 100, and the number and position thereof are arbitrary.
[0030]
In the frame member 10 according to the present embodiment, as illustrated in FIG. 1, the continuous portion of the bottom member 11 and the continuous member 13 is positively formed as a leg portion 15. The center of the member 13 is bent or bent upward. In other words, the frame member 10 is installed on the lath net 21 when the lath net 21 is stretched on the sloped slope 200 as shown in FIGS. 4 and 5. Is. Therefore, in the frame member 10, the first leg 15a, the second leg 15b, the third leg 15c, and the fourth leg 15d, which are clearly shown in FIGS. It protrudes from the mesh of the mesh 21 onto the slope 200, and even if there is irregularities on the slope 200 and the lath net 21 itself floats on the slope 200, it is in close contact with the slope 200. It will be arranged in.
[0031]
Further, in the frame member 10 of the embodiment, as shown in FIG. 2, the top member 12 is curved in a semicircular shape upward in the drawing, because the cross section of the completed frame 100 is shown. This is because it is assumed that the shape is a semicircular shape convex upward. Therefore, if the cross-sectional shape of the frame 100 is trapezoidal, the top member 12 may be bent into a trapezoidal shape. If the cross-sectional shape of the frame 100 is square, the top member 12 is also folded into a square shape. Just tune it. In any case, the top member 12 of the frame member 10 needs to be curved or bent in substantially the same manner as the upper surface outer shape of the modulus frame 100.
[0032]
In addition, about the frame member 10 comprised as mentioned above, it will become more suitable if it forms and implements the non-moving body film | membrane which has the zinc flakes excellent in corrosion resistance and the chromium compound as the main component. This is because the entire surface of the frame member 10 is covered with a coating having excellent corrosion resistance by this non-moving body coating, so that rust does not occur and durability strength does not decrease.
[0033]
