Description

  TECHNICAL FIELD The present invention relates to a method frame for forming a method frame capable of greening a slope (slope) and a method of construction thereof.

  A frame work is used to stabilize the slope. This is because a frame for a frame with reinforcing bars on the inside is installed in a lattice shape parallel to the tilt direction or in the tilt direction and the horizontal direction with respect to the natural slope (slope). Concrete (or mortar) is placed on site. At least one reinforcing bar to be arranged in the mold is necessary to maintain the shape of the normal frame when an external force (particularly tensile force) is applied to the concrete. Patent Document 1 discloses a frame for a legal frame for stabilizing such a slope. Since the main frame for the frame disclosed in Patent Document 1 is mainly intended to stabilize the slope, the section of the mold (height and width) is generally 200 to 300 mm, and the reinforcing bar is 4 in the vertical frame. The main reinforcement.

FIG. 10 is a front view when a conventional formwork is used mainly for slope vegetation.
When only vegetation on a slope with a relatively gentle slope angle is intended, the height of the formwork 51 is generally about 100 to 200 mm. Therefore, in concrete placement, the covering thickness of the rebar 52 is secured and rusted. In order to prevent sticking, it is necessary to arrange the reinforcing bar 52 at the center of the formwork height. In the case of using the frame for a frame disclosed in Patent Document 1 for such an application, in the method of placing a reinforcing bar in advance on a slope, as shown in the figure, the upper bar 54 and the lower bar 55 of the spacer 53 are reticulated. It will be arranged on the upper side of the side frame 56. For this reason, the lower side of the side frame 56 that is not bound by the spacer 53 is easily bent and spread by the pressure at the time of placing the concrete, so that a method frame having an appropriate shape cannot be obtained.

  Patent Document 2 discloses a frame for forming a normal frame in consideration of greening between lattice frames. In the frame method using this frame, a reinforcing bar is installed after the frame is installed. Therefore, when installing the frame on the slope, it is necessary to provide a mark using a rope or the like, and after installing the frame along the mark, it is necessary to remove the mark. It is cumbersome and cumbersome.

  In the present invention, even when using a frame with a relatively small cross section as a slope protection or greening foundation, it is possible to secure a sufficient covering thickness of the reinforcing bar and obtain a frame with an appropriate shape. An object of the present invention is to provide a form for a frame that can simplify the construction process and a method for building a frame using the same.

In order to achieve the object, according to the first aspect of the present invention, there is provided a spacer that is rotatably connected between the left and right mesh-like side frames , the spacer has an upper line and a lower line , and the lower line is divided or continuous. was made from a pair of left and right substantially L-shaped, is fixed to the vertical portion of the left and right L-shaped of the bottom muscle to the upper muscle, the vertical portion of the left and right L-shaped their lower muscle, between the said longitudinal portions mutually it characterized in that the formation of the reinforcing bar holding section lower side is opened to position across the rebar.

In the invention 請 Motomeko 2, in construction law frame using modulo frame for formwork according to claim 1, the reinforcing bar is disposed from the slope at a position of a predetermined height, for the method frame for the iron muscle A frame for a frame is placed on a slope while engaging the reinforcing bar holding portion formed on the frame.

Furthermore, in the invention of claim 3, in the construction of the frame using the frame for the frame of claim 1 , a reinforcing bar is temporarily placed on the slope, and the frame for the frame is made a slope along the reinforcing bar. after placing, characterized in that it binds to lift the iron muscle the method frame mold formed frame in the reinforcing bar holding section.

According to the first aspect of the present invention, the left and right L-shaped vertical portions of the lower bar form the reinforcing bar holding portion formed of a substantially U-shaped space having an open lower side that positions the reinforcing bar between the vertical portions. Therefore, since the reinforcing bar can be easily and accurately positioned at a predetermined position simply by inserting the reinforcing bar into the reinforcing bar holding portion, the reinforcing bar can be easily stored at a predetermined position with respect to the formwork. In addition, since the interval between the binding positions of the upper and lower muscles to the side frame can be widened, the upper and lower muscles can be bound in a well-balanced position so that the distance between the two side frames can be sufficiently maintained, and the concrete inside the mold It is possible to prevent the side frame from being bent and widened by the pressure at the time of placing.

According to the invention of claim 2, since the rebar holding part of the mold is open on the lower side, the rebar is arranged in a substantially U shape after the rebar is floated at a predetermined height with respect to the slope and disposed first. By installing the mold while engaging so as to fit within the reinforcing bar holding portion , the mold can be easily and accurately installed at a predetermined position . For this reason, the reinforcing bar is convenient as a mark when installing the formwork. In addition, the reinforcing bars are accommodated in the reinforcing bar holding part together with the formwork installation, and the reinforcing bar arranging work is completed, so that the reinforcing bar binding work can be performed immediately and the workability is improved.

According to the invention of claim 3, since the lower part of the reinforcing bar holding portion of the mold is open, the reinforcing bar is temporarily placed on the slope, the mold is set up using the reinforcing bar as a mark, and then the reinforcing bar is lifted to substantially Since the reinforcing bar is positioned at a predetermined position by being inserted into the character-shaped reinforcing bar holding part, the binding work of the reinforcing bars can be immediately performed and workability is improved.

FIG. 1 is a perspective view of a formwork frame according to the present invention, and FIG. 2 is a schematic front view thereof.
The form frame 1 for a legal frame according to the present invention is composed of a pair of side frames 2 and spacers 3 made of wire meshes on both the left and right sides. The height of the side frame 2 is, for example, about 100 to 200 mm when the main purpose is slope planting. The spacer 3 is composed of an upper bar 4 and a lower bar 5 and is connected to the side frame 2 so as to be rotatable. As shown in FIG. 1, each connecting portion is formed in a hook shape or a ring shape by folding the end portions of the upper and lower bars 4 and 5, wound around the side frame 2, and rotatably locked. For this reason, the mold 1 can be folded and the side frames 2 can be overlapped, which facilitates conveyance and handling.

The lower line 5 includes a pair of left and right lower lines 5a and 5b having a substantially L shape obtained by bending a straight wire, and is connected to the side frame 2. As described above, one end of each of the lower bars 5a and 5b is locked to the side frame 2, and the other end crosses the upper bar 4, and the crossing portion is fixed by welding or the like. As a result, a substantially U-shaped reinforcing bar holding portion 6 is formed in which the upper side is surrounded by the upper muscle 4 and both sides are surrounded by the left and right lower muscles 5a and 5b. By inserting the reinforcing bar 7 into the reinforcing bar holding part 6 in the substantially U-shaped space formed in the vertical direction in the mold 1 in this way (see FIG. 2), the reinforcing bar 7 has a pair of left and right bottoms as shown. It is sandwiched between the vertical portions of the muscles 5a and 5b and positioned accurately. And after concrete placement, the covering thickness of the reinforcing bar 7 can be sufficiently secured. In addition, about the right-angled bending part of the lower bar | burr 5, it is good also as a structure which gives the rebar 7 into the reinforcing bar holding | maintenance part 6 when the bending process which curves in an arc shape is given and it lifts.

  Moreover, since the space | interval of each bundling position with respect to the side frame 2 of the upper muscle 4 and the lower muscle 5 can be widened, the upper muscle 4 and the lower muscle 5 are shifted to either the upper side or the lower side of the side frame 2. Without being bound, the upper and lower bars 4 and 5 can be bound in a well-balanced position at a position where the distance between the two side frames 2 can be sufficiently maintained, and the side frame 2 is bent by the pressure when concrete is placed in the mold 1. Can be prevented from spreading.

  When installing the formwork 1 on the slope, the reinforcing bars 7 are arranged in advance with a predetermined height with respect to the slope using anchor pins or the like, and the reinforcing bars 7 are attached to the reinforcing bar holding portion 6 whose lower side is opened. It is convenient because the formwork 1 can be installed by using the reinforcing bars 7 as a mark by covering them so as to fit. Furthermore, since the reinforcing bar 7 can be bound to the spacer 3 as it is, the work process is greatly reduced and workability is improved.

FIG. 3 is a front view of the present invention when another spacer is used.
The lower bar 5 of the spacer 3 of the present embodiment has an L-shaped bending angle made obtuse and has a wide open part (rebar fitting part) of the reinforcing bar holding part 6. Thereby, it becomes easy to arrange the reinforcing bar 7 in the reinforcing bar holding part 6 and the workability is improved. Note that one lower bar 5b may be L-shaped by right-angle bending, and the other lower bar 5a may be substantially L-shaped by obtuse angle bending. In this case, it is good also as a structure which hold | maintains the reinforcement 7 elastically using the wire which has elasticity in either the lower reinforcement 5a or 5b, or both. Other configurations, operations, and effects are the same as those in FIG.

FIG. 4 is a front view illustrating a comparative example related to the present invention .
In the lower muscle 5 of the spacer 3 according to this comparative example, in which the lower muscle 5a of the right and left as shown, to expand the distance between 5b, exemplified a case in which two distribution muscle rebar 7 in the horizontal direction, compared Suitable for large size frames with large dimensions. On the other hand, in the case of the present invention, the interval between the pair of left and right lower bars 5a and 5b is narrow as described above, and is set to an interval at which one reinforcing bar 7 can be arranged. It is characterized in that it can be easily positioned by sandwiching the reinforcing bars 7 inserted between the vertical portions of 5b from both sides, and is suitable for a small frame having a relatively small size.

FIG. 5 is a front view of the present invention when still another spacer is used.
(A) is a front view before installation of the mold 1, and (B) is a front view at the time of installation. The upper line 4 of the spacer 3 of this embodiment has one end 4a bent upward and the ends of the lower lines 5a and 5b are wound around the side frame 2. Even with this configuration, the mold 1 can be folded during transportation or storage, and when the mold 1 is installed on the slope, the end 4a of the upper bar 4 and the side frame 2 are bound. Thus, the mold 1 having a trapezoidal cross section can be obtained. Both side frames 2 may be inclined. Since this trapezoidal formwork is used as a horizontal frame and the inclined side frame 2 is arranged on the lower side (back side) of the slope, the slope does not block sunlight against the vegetation base material between the lattice frames. The plant can be grown uniformly and stably. On the other hand, by arranging the inclined side frame 2 on the upper side (top side) of the slope, excess rainwater on the vegetation base material in the grid flows over the law frame to the lower side (麓 side). Plant root rot can be prevented. The end 4a of the upper bar 4 may have a normal hook or ring shape, and the length of the upper bar 4 may be shortened so that the side frame 2 is inclined. Other configurations, operations, and effects are the same as those in the embodiment of FIG. 2, but the lower muscle 5 shown in FIG. 3 may be used.

The lower stripe 5a of the spacer 3 of the present embodiment has a long hole 8 at the hook or ring-shaped ring portion at the connecting portion with the side frame 2. Even with such a configuration, the mold 1 can be folded during transportation or storage, and when the mold 1 is installed on the slope, the vertical line 2a of the side frame 2 is moved in the direction of the arrow. A mold 1 having a trapezoidal cross section can be obtained. Other configurations, operations, and effects are the same as those in the embodiment of FIG. In addition, it is good also as a structure which obtains the effect mentioned above by making the structure of FIG.5 and FIG.6 single or combining, and making both the side frames 2 incline.

FIG. 7 is a front view of the present invention when another spacer is used.
Under muscles 5 of the spacer 3 of this embodiment, the end portion protruding from the side frame 2 upwards, is obtained by the height as that of the legal frame of the concrete after casting. Thus, an operator who sprays concrete after installing the mold 1 can spray the concrete with this height as a guideline to form a frame, so that the work can be performed easily and reliably, and a fixed shape can be obtained. A frame with a good appearance can be obtained (dotted line portion in the figure). Other configurations, operations, and effects are the same as those in the embodiment of FIG.

FIG. 8 is a front view of the present invention when another spacer is used.
The lower stripe 5 of the spacer 3 of the present embodiment is formed by continuously forming the ends of the lower stripe 5a and the lower stripe 5b in FIG. As described above, the above-described effect can be obtained even if the lower wire 5 is bent by one wire. Other configurations, operations, and effects are the same as those in the embodiment of FIG.

FIG. 9 is a flowchart showing an example of a method for constructing a frame using the frame for a frame according to the present invention.
First, the vertical frame reinforcing bars are placed and arranged on the slope, and the horizontal frame reinforcing bars are arranged thereon (step S1). Next, the intersection of the vertical frame reinforcing bar and the horizontal frame reinforcing bar is bound (step S2). Next, the reinforcing bar is lifted and held in a state where the reinforcing bar is floated to a predetermined height by an anchor pin or the like (step S3). Thereafter, the formwork is installed along the reinforcing bars arranged on the slope (step S4), and the reinforcing bars and the formwork are bound (step S5). Next, concrete (or mortar) is placed in the mold (step S6) to form a method frame.

  Although not shown, as another construction method using the formwork of the present invention, a method in which Step S3 and Step S4 are reversed, that is, reinforcing bars are arranged on the slope, and then the formwork is arranged on the reinforcing bars. Then, the reinforcing bars may be lifted and bound to the formwork.

As described above, in the method for constructing a frame according to the present invention, since the reinforcing bars are arranged on the slope in advance and the formwork is installed along the reinforcing bars, the formwork can be installed using the reinforcing bars as a mark. The formwork can be installed at a predetermined position without requiring a positioning mark. For this reason, the work of arranging or removing the mark for installing the mold can be omitted, and the number of work steps is reduced. In addition, since the reinforcing bar is simply and accurately positioned by inserting the reinforcing bar into the reinforcing bar holding part formed in the mold , and the reinforcing bar is placed in a predetermined position in the mold, the binding work of the reinforcing bars simultaneously with the installation of the mold Therefore, workability is improved.
