Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a frame for forming a legal frame used for greening slopes such as roads and land for construction.

[0002]

[Prior art]

 When greening the slope, lay a mesh such as a wire mesh on the slope, arrange the reinforcing bars in a grid on the mesh, and concrete or mortar (hereinafter referred to as mortar etc.) to embed the reinforcing bars. To form a grid-shaped law frame, and spray the vegetation material mixed with various seeds and fertilizers, or place the vegetation bag loaded with the above-mentioned vegetation material inside the law frame. Then, there is a construction method (see, for example, Japanese Patent Publication No. 58-20338) in which various seeds contained in the vegetation material are germinated and grown within the law frame while protecting the expulsion of the vegetation material by the lattice method frame described above. .

According to the current civil engineering standards, the thickness of mortar or the like covering the above-mentioned reinforcing bar (referred to as “covering thickness”) is 5 cm or more from any surface of the reinforcing bar. It is well known that it is obligatory as a quality control standard for obtaining.

[0004]

[Problems to be solved by the device]

 However, since the spraying of mortar, etc. is performed in an unstable place on the slope, the thickness and width of spraying mortar, etc. on the reinforcing bars tend to be non-uniform, which is equivalent to forming a grid-like method frame of a predetermined size. In addition to requiring a high level of skill, it was unavoidable that the dimensions and strength of the grid-shaped method frame varied.

Further, since it is necessary to separate the reinforcing bar from the slope by 5 cm or more, the above-mentioned reinforcing bar is floated on the slope by floating the reticulated body or by using an anchor pin. , The mortar, etc. are sprayed or other work, the net-like body must be stepped on, or by accidentally bending the reinforcing bar or knocking down the anchor pin. It was not possible to ensure the height position as specified, and further it was not possible to confirm from the outside whether or not a layer of mortar, etc. was formed around the reinforcing bar with a specified thickness, and this met the standards. In rare cases, a grid-like method frame was not formed.

The present invention has been made in view of the above circumstances, and it is possible to easily form a lattice-shaped frame according to standard dimensions without requiring skill, and moreover, to reliably position the reinforcing bar at that time. In addition to being achieved, the objective is to provide a framework for forming a legal framework that enables a significant increase in legal framework strength.

[0007]

[Means for Solving the Problems]

 The frame body for forming a legal frame according to the present invention, which has achieved the above object, is arranged so as to straddle the reinforcing bars arranged in a grid on the slope and is sprayed with concrete or mortar to form the legal frame. The frame body is composed of a plurality of trapezoidal horizontal wire rods having a pair of legs on both sides in the longitudinal direction and a plurality of vertical wire rods connecting the horizontal wire rods to each other. A characteristic is that a holding member with a hook formed at the lower end is hung from the wire rod on the ceiling or the rebar placed on it, and the rebar inside the frame is erected and held by the holding member at the middle of the horizontal wire rod in the height direction. is there.

In addition, instead of the horizontal wire having a trapezoidal shape in front view, a polygonal shape of a triangle or more, an arched shape, or one or more concave portions formed by bending the upper side once or more to form a front view It may be a concave polygon. Preferably, a reinforcing bar is placed on the frame body, the holding member is hung from the reinforcing bar on the frame body, and the reinforcing bar in the frame body is erected and held by the holding member.

[0009]

[Action]

 According to the frame body for forming a legal frame having the above-mentioned characteristic structure and the legal frame construction method using the frame body, the frame bodies are arranged in a lattice pattern on the slope at a predetermined pitch, and the hook portion of the holding member is used. A predetermined lattice-shaped method frame is formed on the slope by installing the reinforcing bars and spraying mortar or the like so as to embed them.

At this time, in addition to the position of the reinforcing bar being determined by the holding member, since the frame serves as a guide for the spraying width and the spraying height of the motor, the height and width dimensions of the frame are If the mounting position of the holding member is set in advance based on the quality control standard for obtaining the grid-shaped frame with a predetermined strength, the mortar etc. can be simply embedded in the vertical and horizontal frames including the reinforcing bars. It is possible to easily form a lattice-shaped method frame having a predetermined size and strength in a state where the reinforcing bar is embedded with a covering thickness of a predetermined size, without requiring any skill, simply by spraying.

If the frame is trapezoidal or arcuate when viewed from the front, the frame itself has an excellent function in terms of installation stability on the slope, and further, in such a configuration, the frames are superposed. There is no need to say that it is suitable for transporting, and at this time, by taking the form in which the holding member is detachably / floatably attached and detaching or folding the holding member, it is possible to further improve the transportation surface. It goes without saying that it will be a thing.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a state in which a lattice-shaped method frame 1 formed by using the frame body according to the first embodiment of the present invention is in the process of being formed.

The grid-shaped method frame 1 will be described later in terms of its forming procedure. First, a mesh body 2 such as a wire mesh is laid on the slope A, and the reinforcing bars are arranged on the mesh body 2 at a predetermined pitch. 3 are arranged in a lattice shape, and a plurality of frame bodies 4 and 5 are arranged vertically and horizontally so as to straddle the reinforcing bar 3, and the lattice frame body 6 is formed by these vertical and horizontal frame bodies 4 and 5. In addition, the reinforcing bar 3 is floated and held together with the mesh body 2 at a predetermined height position, and another reinforcing bar 7 is arranged above the vertical and horizontal frame bodies 4 and 5, and the reinforcing bars 3 and 7 are included in the vertical and horizontal directions. It is formed by spraying mortar 8 and the like so as to embed the frame bodies 4 and 5.

When the mortar 8 or the like is sprayed, it is important to lay a sheet 9 on the lattice-shaped portion surrounded by the vertical and horizontal frames 4 and 5 to cure the non-sprayed portion of the mortar 8 or the like.

Then, after spraying the mortar 8 and the like, the sheet 9 is removed, and the curing portion from which the sheet 9 is removed includes various seeds and fertilizers such as turf grass, wild grass and shrubs, and soil and organic matter. A variety of seeds contained in the vegetation material 10 is protected by spraying the vegetation material 10 mixed with wood and water retention material (soil conditioner) and protecting the runoff of the vegetation material 10 with the grid-shaped method frame 1. It germinates and grows inside. In addition, there is a case where a vegetation bag in which a vegetation material is loaded is placed in the above-mentioned curing portion so as to be green.

Next, the structure of the vertical and horizontal frame bodies 4 and 5 used in the above method of frame construction will be described with reference to FIGS. 2 to 4. Both have a trapezoidal shape when viewed from the front so that they are superior in terms of the stability of the installation posture as well as the transporting surface when stacked, that is, the pair of linear ceilings 11a is slanted downward from both sides in the longitudinal direction. A horizontal wire rod 11 having a trapezoidal shape having extended leg portions 11b, and a plurality of vertical wire rods 12 connecting the leg portions 11b to each other. A hanging hook 13b formed on the upper end of the holding member 13 is engaged with the ceiling portion 11a to suspend the holding member 13. The hook portion formed on the lower end of the holding member 13 is suspended. 13c should be located in the middle of the horizontal wire 11 and the slope A in the height direction. It is provided in.

Specifically, the ceiling 11a of the horizontal wire 11 has a length of about 18 cm, the dimension between the lower ends of the pair of legs 11b, 11b is about 30 cm, and the height thereof is about 9 cm. The horizontal wire 11 is welded in the lengthwise direction of the vertical wire 12 with a pitch of, for example, about 20 cm. The length of the vertical wire 12 (that is, the length of the vertical and horizontal frames 4, 5 alone) is about 300 cm, and is 2.30 below the upper end of the leg 11b. Three pieces are welded at a pitch of about 5 cm.

For example, when the length of one span of the lattice frame is 150 cm, two holding members 13 are provided at a pitch of about 50 cm at the middle portion in the length direction. The hook 13b is engaged with a substantially central portion of the ceiling portion 11a of the predetermined horizontal wire 11, and the reinforcing bar 3 is engaged with the hook portion 13c formed at the lower end thereof.

In this embodiment, the holding member 13 is configured to be engaged with the horizontal wire 11 by the hanging hook 13b, so that the holding member 13 can be installed at intervals of the frame body 4. 5 can be arbitrarily changed with respect to the lengthwise direction, and in some cases, it is also possible to provide them at intervals longer than the above 50 cm.

The horizontal wire member 11, the vertical wire member 12, and the holding member 13 are made of, for example, a wire having a diameter of about 4 mm and subjected to rust-proof processing, and the holding member 13 is detachable from the horizontal wire member 11. Therefore, when carrying the vertical and horizontal frames 4 and 5, the holding member 13 can be detached from the frames 4 and 5 with which it is engaged, and the frames 4 and 5 can be easily overlapped and carried. I am trying.

Next, when forming the lattice-shaped method frame 1 on the slope A, first, the reticulated body 2 such as a rhombic wire mesh having a mesh of, for example, about 5 to 6 cm is formed on the pre-shaped slope A. The mesh 2 is laid and appropriately fixed by an anchor (not shown), and the water thread 14 is arranged at a pitch based on the total size of the span length and the frame width of the vertical and horizontal frames 4 and 5 (see FIG. 1). Are stretched in a grid shape, the reinforcing bars 3 are arranged on the mesh body 2 along the water threads 14, and a plurality of vertical frame bodies 4 are installed so as to straddle the reinforcing bars 3 arranged in the grid shape. Then, a horizontal frame body 5 obtained by cutting the wire on the side surface of the intersection is provided so as to be orthogonal to the vertical frame body 4, and the lattice frame body 6 is formed by the vertical and horizontal frame bodies 4 and 5.

At this time, in addition to the fact that the position of the reinforcing bar 3 is fixed by the vertical and horizontal frames 4 and 5, the vertical and horizontal frames 4 and 5 serve as a guide for the spray width of the mortar 8 and the like. In addition, by simply spraying the mortar 8 etc. so as to fill the vertical and horizontal frames 4 and 5, the grid-shaped method frame 1 having the predetermined size and strength in the state where the reinforcing bar 3 is embedded with the covering thickness of the predetermined size is obtained. It can be formed.

That is, in this embodiment, the height of the reinforcing bar 3 floated by the holding member 13 from the slope A is set to 5 cm, and the circumference of the reinforcing bar 3 is fixed to a predetermined thickness (5 cm by the mortar 8 or the like). As described above, the lattice-shaped method frame 1 having a lower end width of about 30 to 40 cm and a height of about 15 to 18 cm is formed.

In the above embodiment, as shown in FIG. 5, when the reinforcing bar 3 is configured to be bound to the reticulated body 2 by a binding wire 17, the rebar 3 and the reticulated body 2 are hooked together with the hook portion 13c. Will be mobilized to. In this case, since the mesh body 2 is floated at a height position of 5 cm from the slope A, the layer of the vegetation material 10 (see FIG. 1) surrounded by the lattice frame body 1 is more than 5 cm. When it is thick, it is effective for preventing the vegetation material 10 from running away.

Further, as shown in FIG. 6, the mesh body 2 may be floated on the slope A by a spacer 22 at an appropriate interval. In this case, the slope A of the mesh body 2 is opposed to the slope A. The height position can be changed arbitrarily, and thus the thickness of the vegetation material 10 can be changed arbitrarily. The spacer 22 may be, for example, "Slope protection lath spacer" of the applicant's application for design registration No. 4418 in 1988, or Japanese Utility Model Publication No. 5-42118. The "spacer pin" can be preferably carried out.

Further, in order to improve the strength of the method frame 1, after the reinforcing bar 3 and the mesh body 2 are placed on the hook portion 13c, the reinforcing bar 3 and the mesh body 2 are hooked with a binding wire or the like. The hooks 13c can be securely connected to the reinforcing bars 3 and the mesh 2 in this case. Further, another reinforcing bar 7 is mounted on the substantially central portion of the ceiling portion 11a of the vertical and horizontal frames 4 and 5, and this reinforcing bar 7 is coupled and integrated with the ceiling portion 11a by a binding wire rod 19 and the mortar 8 is formed. It is also possible to make changes such as increasing the strength of the legal frame 1 by making the spray thickness of the etc. appropriate.

In the case where the holding members 13 are detachably engaged as in the above-described embodiment, the frame bodies 4 and 5 have a trapezoidal shape when viewed from the front, a bow-shaped shape when the end view is widened in the front view, and the like. As described above, it is preferable that the holding members 13 and the frame bodies 4 or 5 are disengaged from each other, so that the frame bodies 4 and 5 can be overlapped and transported. It may be fixed to the ceiling portion 11a by means such as welding, and by doing so, the mounting position of the reinforcing bar 3 by the hook portion 13c can be ensured.

Further, a recess for fitting the hanging hook 13b of the holding member 13 may be formed in a substantially central portion of the ceiling portion 11a, and the hanging hook 13b may be used as a binding wire. For example, it may be bound to the horizontal wire 11. By doing so, the shift of the holding member 13 in the lateral direction as viewed from the front can be eliminated.

Alternatively, a loop portion may be formed on the upper end of the holding member 13, the loop portion may be always coupled to the ceiling portion 11a of the horizontal wire 11, and the loop portion may be rotatably connected around the loop portion. In this case, when the vertical and horizontal frames 4 and 5 are stacked and transported, the holding member 13 can be folded so as not to get in the way.

In all of the above embodiments, the holding member 13 was engaged with the horizontal wire 11. However, the holding member 13 may be configured as shown in FIGS. That is, FIG. 7 and FIG. 8 are a partially exploded perspective view and a vertical sectional view, respectively, showing the constitution of the law frame according to the second embodiment of the present invention. In these drawings, the members denoted by the same reference numerals as those in FIGS. 1 to 4 are the same or equivalent members, and thus detailed description thereof will be omitted.

In these drawings, reference numeral 12a is a vertical wire rod that connects the central portions of the ceiling portion 11a of the horizontal wire rod 11 in a front view to each other, and reference numeral 7 is an upper reinforcing bar provided along the vertical wire rod 12a. On the other hand, a hanging hook 13b is formed at the upper end of the holding member 13, and the holding member 13 is hung on the ceiling portion 11a by engaging the hanging hook 13b with the upper rebar 7. At the same time, the upper hook 7 and the vertical wire 12a are held by the hanging hook 13b. Therefore, since the two reinforcing bars 3 and 7 are embedded in the lattice method frame 1, the strength thereof can be greatly improved, and the installation position of the suspending hook 13b can be displaced in the left-right direction when viewed from the front. Can be completely prevented.

In this case, an inspection pin, which serves as a guide for spraying the mortar 8 and the like with a predetermined covering thickness on the upper reinforcing bar 7, is vertically driven from near the vertical wire 12a. In order to embed the horizontal and vertical frames including the reinforcing bars 3 and 7, for example, by spraying a low slump mortar 8 having a water content of about 7 to 8% with a mortar gun machine, etc. 1 may be formed.

Alternatively, although not shown, the upper rebar 7 may be bound to the vertical wire 12a by a binding wire or the like. In this case, the hanging hook 13b is engaged with the vertical wire 12a. Good. Further, when the strength is sufficient, by omitting the upper rebar 7, it becomes possible to simplify the installation work of the frame body and to make the height of the legal frame 1 low. In any of these forms, the legal framework 1 is based on the quality control standards obliged by the current civil engineering standards, and the covering thickness of the reinforcing bar due to the mortar 8 etc. from any surface of the reinforcing bar. It goes without saying that the size is set to be 5 cm or more.

In addition, although not shown in the drawing, two vertical wires 12a are provided in parallel at intervals of 5 cm, and the holding member 13 is engaged with each of the vertical wires 12a, 12a. It is also possible to arrange two rebars 3 and 3 side by side in a front view, and if the upper rebars 7 and 7 are provided along the two vertical wires 12a and 12a, respectively, It is possible to embed a total of four reinforcing bars in one.

FIG. 9 and FIG. 10 are vertical cross-sectional views of the method frame showing the configuration of the frame body according to still another embodiment of the present invention. In both figures, 11 'is a horizontal wire which constitutes a vertical and horizontal frame, and the shape of this horizontal wire 11' is a pentagon in FIG. 9 and a bow in FIG. Both sides in the length direction of the horizontal wire 11 'are leg portions 11b, 11b. A suspending hook 13b is formed on the upper end of the holding member 13, and the suspending hook 13b is engaged with the wire rod or the upper reinforcing bar 7 of the ceiling portion of the frame body, so that the retaining member 13 has the ceiling portion 11a. Is hung on.

In both figures, the members given the same reference numerals as those of the frame body 1 of the first and second embodiments and their modifications shown in FIGS. 1 to 8 are the same or equivalent members, Detailed description is omitted. In addition, it goes without saying that the modified examples described in detail in the above-described first and second embodiments can be similarly applied to the present embodiment.

FIG. 11 is a vertical cross-sectional view of a method frame showing a structure of a frame body according to still another embodiment of the present invention. In the figure, 11d is a ceiling portion of the horizontal wire 11, and the ceiling portion 11d forms a holding member engaging portion 11h bent downward at a substantially central portion thereof. Therefore, this frame is M-shaped when viewed from the front.

In this embodiment, since the holding member engaging portion 11h bent downward is provided, the hanging hook 11b provided at the upper end of the holding member 13 is the holding member 13 and this hook. Due to the weight of the reinforcing bar 3 placed on the part 13c, the position is fixed to the holding member engaging part 11h, and the construction can be simplified. Further, the upper reinforcing bar 7 can be stably placed on the holding member engaging portion 11h, and the frame body for forming the method frame can be provided with a very simple configuration and method as a whole.

Since the other components are the same as or equivalent to the frame body 1 of the first and second embodiments shown in FIGS. 1 to 6, the same reference numerals are given and a detailed description thereof will be given. Omit it. Further, it goes without saying that the modified examples already described in detail in the above-mentioned first and second embodiments can be similarly applied.

In addition, in each of the above-described embodiments, the lower end portion of the leg portion 11b of each of the horizontal wire members 11 and 11 'may be bent outward or inward to provide a sunken piece.
