Description

  The present invention relates to a method frame mold used for slope stabilization, and more particularly, to a method frame mold for forming a method frame for the purpose of greening a slope.

  A frame for a legal frame is usually composed of a pair of metal meshes and a plurality of spacers disposed between the metal meshes (see, for example, Patent Documents 1 to 6). In such legal formwork, not only “stabilization” of the slope but also “greening” may be the main purpose. When “greening” is the main purpose, the formwork mold (legal frame) is used. ) Is kept to the minimum necessary, and the height of the legal frame form (legal frame) is kept as low as possible.

Japanese Patent No. 2694330 JP 2000-192468 A JP 2001-226975 A JP 2004-346616 A JP 2005-611144 A JP 2005-133499 A

  However, in the above-mentioned frame forms for patent frames 1 to 6, the ends or bent portions of the vertical bars and horizontal bars (bars) constituting the spacer protrude above the reinforcing bars provided inside the mold frame. Therefore, there is a problem that the protruding portion obstructs the binding work of the spacer and the reinforcing bar, the binding of the spacer and the reinforcing bar is difficult, and the workability is poor.

  In addition, the height of the frame is increased because the end or bent part of the bar or vertical bar that constitutes the spacer protrudes upward from the reinforcing bar. A shaded part is formed in the vegetation area, which is not preferable from the viewpoint of greening the slope.

  Therefore, the present invention has been made paying attention to such problems, and can improve the bundling workability between the spacer and the reinforcing bar, and can also suppress the height of the legal frame to the minimum necessary. It aims at providing the formwork for frames.

In order to achieve the above object, a method frame mold according to the present invention is a method frame mold in which a plurality of spacers made of bar material are arranged at a predetermined interval between a pair of wire meshes. Has at least two bar members, and each of the two bar members is connected to one wire mesh on both sides and the other end connection portion connected to the other wire mesh. A horizontal portion extending horizontally from the one end side connecting portion toward the other end side connecting portion at least at the center between the metal meshes, and from the bent portion to the other end side connecting portion. And an inclined portion extending obliquely downward, and is provided in a positional relationship that is symmetrical with respect to the center line between the wire meshes.
Here, the lengths of the horizontal portion and the inclined portion of each of the two bars are substantially the same, and when the two bars are provided in a positional relationship that is symmetrical between the pair of wire meshes, The bent portions may be overlapped.

According to the formwork frame for a frame according to the present invention, the spacer has two bar members, and each of the two bar members is at least between the wire meshes from the one end side connecting portion toward the other wire mesh. A horizontal portion extending horizontally to the bent portion located at the center or more of the center, and an inclined portion extending obliquely downward from the bent portion toward the other end side connecting portion, with respect to the center line between the wire meshes The positions were set so as to be symmetrical. Therefore, by arranging the rebars according to the height of the horizontal part, the end or bent part of the bar material such as vertical bars and horizontal bars that make up the spacer does not protrude upward from the rebars. Are easy to bundle, workability is improved, and the height of the wire mesh is minimized, which is preferable from the viewpoint of greening the slope. Further, since the two bar members constituting the spacer may be symmetrical, there is an effect that the number of parts can be reduced.
In addition, when the lengths of the horizontal portions and the inclined portions of the two bars are substantially the same, and the two bars are provided in a positional relationship that is symmetrical between the pair of wire meshes, When the bent portions are overlapped, a simple formwork frame can be constructed in which only one reinforcing bar is provided immediately below the bent portion.

It is a perspective view of the bar material which constitutes the spacer of the form frame for a legal frame concerning the present invention. (A)-(c) It is explanatory drawing which shows the construction procedure of the legal frame which uses the form frame for legal frames which concerns on this invention, respectively. It is a front view of the other example of the form frame for legal frames which concerns on this invention.

  FIG. 1 is a perspective view of a formwork frame 1 according to the present invention, FIG. 2 is a front view of the formwork frame 1 according to the present invention, and FIG. 3 is a view of the formwork frame 1 according to the present invention. 3 is a perspective view of a bar 31 that constitutes a spacer 3. FIG. As shown in FIGS. 1 and 2, the frame 1 for a legal frame according to the present invention includes a pair of metal meshes 2, a spacer 3 composed of two bar members 31, 31, and a pair of metal meshes 2, 2. A plurality of reinforcing bars 4 are arranged at predetermined intervals in the longitudinal direction of 2, one or a plurality of reinforcing bars 4 are provided in the longitudinal direction and bound to the spacer 3, and then concrete or mortar is placed on the formwork frame 1 for the frame. The frame is constructed by flowing or spraying.

  As shown in FIG. 2, the spacer 3 is composed of two rods 31 and 31 having the same size and shape, and is positioned symmetrically with respect to the center line M between the wire meshes 2 and 2. Established in relationship. As shown in FIG. 3, the bar 31 is folded at both sides into a hook shape or a ring shape and connected to one wire mesh 2 and the other end connection portion connected to the other wire mesh 2. 31b1 is provided, and is locked to the left and right metal meshes 2, 2 so as to be rotatable. For this reason, it is possible to fold and overlap the frame 1 for the frame consisting of the pair of wire nets 2 and 2 and the spacer 3, and the handling at the time of storage and transportation becomes convenient.

  In the frame 1 for the frame according to the present embodiment, the two bar members 31 constituting the spacer 3 are respectively arranged between the wire meshes 2 and 2 from the one end side connecting portion 31a1 toward the other end side connecting portion 31b1. A horizontal portion 31a extending horizontally to the central bent portion 31c and an inclined portion 31b extending obliquely downward from the bent portion 31c toward the other end side connecting portion 31b1.

  Here, in the frame 1 for the frame according to the present embodiment, the horizontal lengths of the horizontal portions 31a and the inclined portions 31b of the two bar members 31 constituting the spacer 3 are substantially the same. For example, if the distance between the metal meshes 2 and 2 is, for example, 250 mm, the horizontal length of the horizontal part 31a and the inclined part 31b is 125 mm, which is 1/2 of 250 mm that is the distance between the metal meshes 2 and 2, respectively.

  Therefore, the bent portions 31c of the two bars 31 are provided at positions overlapping the center line M between the wire meshes 2 and 2, as shown in FIG. Join by welding at points. As a result, it is possible to construct a simple frame 1 having only one reinforcing bar 4 as shown in FIG. 1 immediately below the bent portions 31c of the two bars 31. In the present invention, the bent portions 31c and 31c of the rods 31 and 31 may be joined together by welding or the like, or may not be joined.

  Next, a procedure for constructing a legal frame using the legal frame mold 1 configured as described above will be described with reference to the drawings.

  First, as shown in FIG. 4A, after a lath wire mesh 6 is stretched on the slope 5, the reinforcing bar 4 is temporarily placed. Next, as shown in FIG. 4 (b), the reinforcing frame 4 is used as a guide so that the reinforcing frame 4 is positioned approximately at the center between the pair of wire meshes 2 and 2 of the fixing frame 1. Spread it out.

  Next, as shown in FIG.4 (c), the bending part which is the crossing point of the horizontal part 31a of each bar 31, and the inclined part 31b, ie, the location where the two bars 31 cross the reinforcing bar 4 Pull up to 31c and bind with a binding wire (not shown).

  After the method frame 1 and the reinforcing bars 4 are bound on the slope 5 as described above and a plurality of method frame molds 1 are installed, at the intersections (connection points) between the method frame molds 1. Is installed with a known main anchor (not shown) or the like, while a known auxiliary anchor (not shown) is installed on the outer frame 1 for a plurality of frame frames 1. After fixing to the connection or slope 5, the mortar is sprayed to construct the frame.

  As described above, in the frame 1 for the frame according to the present embodiment, the spacer 3 has the two bar members 31, and the two bar members 31 are folded into the horizontal part 31a and the inclined part 31b, respectively. And the bent portions 31c of the two bar members 31 are arranged so as to overlap each other by being provided in a positional relationship that is symmetrical with respect to the center line M between the metal meshes 2 and 2. Then, the rebar 4 is pulled up and bound to the overlapping bent portion 31c from below until it comes into contact with the bar 31. For this reason, the end portion and the bent portion of the bar 31 constituting the spacer 3 do not protrude above the reinforcing bar 4 (note that the reinforcing bar 4 is disposed below the bar 31, so that the reinforcing bar 4 is positioned above the reinforcing bar 4. Since the outer diameter of the bar 31 protrudes), the spacer 3 and the reinforcing bar 4 are easily bound, and the workability of the binding work and the like is improved. Further, the two bars 31 are the same, and no vertical bar is required, so that the number of parts can be reduced.

  Further, in the frame 1 for the frame according to the present embodiment, since the end portion and the bent portion of the bar 31 constituting the spacer 3 do not protrude upward from the rebar 4, the height of the spacer 3 itself can be kept low. The height of the metal meshes 2 and 2 can be minimized. As a result, the height of the completed frame can be kept as low as necessary, which is preferable from the viewpoint of greening the slope 5.

  Further, when the distance between the metal meshes 2 and 2 is set to 250 mm as described above, for example, the two bar members 31 constituting the spacer 3 are formed by the horizontal portion 31a and the inclined portion 31b as shown in FIGS. The horizontal length is approximately the same 125 mm. Since the inclined portion 31b is inclined by about 15 degrees with respect to the horizontal portion 31a, if the horizontal length is 125 mm, the actual length of the inclined portion 31b is about 128.5 mm. Therefore, the length of both the horizontal part 31a and the inclined part 31b is set to about 125 mm, and the insufficient length 3.5 (= 128.5-125) mm of the inclined part 31b is supplemented by the other end side connecting part 31b1. Then, it becomes possible to construct the spacer 3 by using the two bar members 31 without worrying about the directions of the horizontal portion 31a and the inclined portion 31b. That is, if the horizontal portion 31a of the bar 31 is tilted in the direction of lowering by 15 degrees, it becomes the inclined portion 31b. In this case, the inclined portion 31b is raised by 15 degrees to become the horizontal portion 31a, so the orientation of the horizontal portion 31a and the inclined portion 31b is changed. The spacer 3 can be constructed using two bars 31 without worrying.

  In the spacer 3 described above, as shown in FIG. 2, the horizontal lengths 31a and 31b of the bar 31 constituting the spacer 3 are made substantially the same in the horizontal direction, and the wire meshes 2 and 2 are respectively separated. However, in the present invention, the present invention is not limited to this, and the other end side connecting portion in which the bent portion serving as the boundary between the horizontal portion and the inclined portion is located more than the center between the wire meshes 2 and 2. It may be positioned on the 31b1 side. For example, as shown in FIG. 5, two bars 31 in which the length of the horizontal part 31 a ′ of the bar 31 ′ constituting the spacer 3 ′ is about three times the horizontal length of the inclined part 31 b ′. 'May be provided in a positional relationship that is symmetrical with respect to the center line M between the pair of wire nets 2 and 2. If it does in this way, since bending part 31c ', 31c' of each bar | burr 31 and 31 'will not correspond, but will separate | separate, as shown in FIG. It is possible to construct a method frame mold 1 ′ that can be provided in the bent portions 31c ′ and 31c ′.
