[0006]
[Problems to be solved by the invention]
However, each of the molds described in the above publication only bends or covers only the wire that protrudes from the upper side of a pair of opposing wire mesh side frames . Ie, the <1> law frame for formwork publications, although wound by bending the upper end of the vertical line with respect to the horizontal line of the uppermost constituting the mold upper, the vertical line of the lower side Is in a state of being cut off with the end portion protruding downward from the horizontal line . Upper SL law frame wire mesh of publications <2> is covers the vertical and horizontal lines of a synthetic resin material to only the upper edge of the wire mesh upper side, the lower edge of the lower side projecting vertical lines below It is in a state of being cut as it is. As for the upper side covered, the vertical line protrudes from the horizontal line in the same manner as the lower side . Upper SL formwork <3> is are fixed in the lateral direction of the steel wire by bending the longitudinal upper edge of the steel wire, the <1> for the lower edge, as in the publication of <2> The longitudinal steel wire protrudes and remains uncut.
[0007]
If the end of the vertical line protrudes on the lower side of the mold as in the above prior art , the following problems occur.
(1) When the formwork is installed on the natural slope, the edge of the vertical line bites into the natural ground, especially on soft ground, and the height of the formwork is reduced to obtain the design height Therefore, the predetermined stabilization may not be achieved. To cope with this, extra concrete is sprayed higher than the formwork according to the amount of bite of the vertical line, or the height of the vertical line is presumed in advance according to the site. It is necessary to make a formwork. Such extra concrete placement and formwork addition in the field are troublesome and workability is reduced.
(2) When storing or transporting the formwork or carrying it to the installation site on the site, there is a risk of clothing touching the protruding vertical line on the lower side, or touching other members, resulting in damage. Attention is required. For this reason, the packaging for transportation must also be made strict.
(3) When the position is to be corrected after placing the formwork once at the installation location, lift the formwork, remove the bitten vertical line from the ground, and lift the whole formwork The position must be shifted, requiring a lot of labor and poor workability. For example, there is a case where a rhine wire net is laid on the ground surface to stabilize the soil for planting. In this case, after temporarily placing the formwork, even if trying to shift it to a predetermined position, a vertical protrusion that protrudes to the lower side of the formwork It is very difficult to correct the position because the line is caught on the wire.
[0008]
The present invention takes the above-mentioned conventional technology into consideration, and prevents a bite into a natural mountain when installed on a slope to ensure a predetermined formwork cross-sectional area, and is easy to handle during storage and carrying. The purpose of the present invention is to provide a form frame for legal frame that is easy to pack, can be easily adjusted and corrected when installed on site, and has improved workability.
[0009]
[Means for Solving the Problems]
In order to achieve the above object, in the invention of claim 1, in a form frame for a normal frame in which a pair of mesh-like side frames intersecting a vertical line and a horizontal line are connected by a spacer, and the horizontal line is a longitudinal direction, the upper end of the vertical line The technical means of alternately bending the lower and lower ends and winding them around the horizontal lines of the upper side and the lower side and positioning the end on the other end side inside the upper side or the lower side was adopted. According to this configuration, the vertical line does not protrude from the lower side as well as the upper side, and the lower side of the mold is aligned substantially flat (linearly) together with the upper side. Thereby, a predetermined formwork cross-sectional area is ensured, the handling property at the time of storage and carrying is good, and packing is also easy. Furthermore, it is possible to improve the possible workability easily positioning and modifications during installation at the current spot. Moreover, since the upper side and the lower side have the same shape, it is not necessary to confirm the upper and lower sides at the site, and the workability is further improved . Further, by winding the horizontal upper and lower ends of the vertical lines is folded alternately, and the vertical and horizontal lines in upper and lower sides that holds reliably bonded to the mold shape.
[0010]
In the invention of claim 2, in a frame for a frame of law in which a pair of mesh-like side frames intersecting a vertical line and a horizontal line are connected by a spacer composed of upper and lower horizontal bars and vertical bars connecting the horizontal bars , spacer, the horizontal bar of its relative longitudinal line of the side frame, and vertically movable by slidably mounted vertically, up and down the upper and lower ends of the vertical bars of the mesh side frame at the upper limit position of the spacer both A technical means was adopted in which the vertical bar protruded below the lower edge of the mesh-like side frame at the lower limit position of the spacer, which fits between the edges . According to the configuration of this, by the spacer impart a play in the vertical direction without fixing to network-side frame (a slidable), at the time of mold transported by moving the spacer to the upper limit position of the play the entire spacer Fits within the vertical width of the reticulated side frame, and the lower end of the vertical bar can be retracted above the lower edge of the reticulated side frame.When using the formwork, the spacer is lowered to the lower limit of play and the lower end of the vertical bar is moved to the reticulated side. It can project below the lower edge of the frame. As a result, the vertical bars are not caught during transportation, handling is simplified and packaging is simplified. Can be smooth. The play of the spacer may be movable by free fall, or may be moved by hand with a light slide resistance. If free fall is possible, the spacer moves downward only by turning the mold upside down. When the position is changed after the formwork is installed, the position can be adjusted by lifting the spacer. Therefore, the position can be changed more easily than in the case where the spacer protrudes and is fixed as in the prior art.
[0011]
In addition, you may make it wind the edge part of the horizontal line of the said net-like side frame around the vertical line of a horizontal direction both ends (Claim 3). According to the configuration of this, the end portion of each horizontal line of the mesh side frame is wound on the vertical line side, since the end portion of hewn does not project beyond the vertical line, the horizontal line ends workers and those It is easy to handle because it is not caught or damaged. Also, when folding and packing the formwork during transportation or carrying, it is no longer necessary to cover and protect both ends of the mesh side frame with corrugated cardboard, etc. And the packaging work is simplified.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic overall view of a form frame for a legal frame according to an embodiment of the present invention, and FIG. 2 is a detailed view of a part A and a part B thereof. As shown in the figure, the frame 1 for the frame is composed of a pair of left and right reticulated side frames 2 and a spacer 5 connecting them. In this example, each mesh-shaped side frame 2 is formed of a crimp wire mesh in which vertical lines 3 and horizontal lines 4 are woven in a lattice pattern. The spacer 5 is formed by connecting upper and lower horizontal bars 6 and left and right vertical bars 7 in a cross-beam shape, and a plurality of spacers 5 are provided at predetermined intervals along the longitudinal direction of the mesh-like side frame 2 (only one is shown in the figure). ). Both ends of the upper and lower horizontal bars 6 are rotatably attached to the vertical line 3 of the mesh-like side frame 2. Thereby, the net-like side frame 2 can be folded and folded.
[0013]
For example, every other vertical line 3 of the reticulated side frame 2 has an upper end at the uppermost horizontal line 4a (the horizontal line on the upper side of the reticulated side frame 2), as shown in FIG. The lower end is cut at a position above the lowest horizontal line 4b (the horizontal line on the lower side of the net-like side frame 2). Further, the vertical lines 3b alternately arranged between the vertical lines 3a whose upper ends are bent are conversely wound around the horizontal lines 4b whose lower ends are the lower sides as shown in FIG. The upper end is cut at a position below the horizontal line 4a on the upper side. As a result, the length of each vertical line 3 is shorter than the length between the upper side and the lower side of the mesh side frame 2, and the upper and lower ends of each vertical line 3 do not protrude vertically from the mesh side frame 2. The upper and lower sides of the frame are substantially flat (straight). At this time, by folding the end portion of the vertical line inward, the folded end portion is not exposed to the outer surface of the net-like formwork, and is prevented from being caught during work, and the finishing operation of the outer surface is smooth. I can . Contact name vertical lines 3a to bend at the upper side 4a or lower 4b, the position of the 3b, if a position vertical line 3 is folded from the outside to the inside by the position of the wave of the wavy horizontal lines 4, vertical lines 3 of which position It may be.
[0014]
In addition, about a mesh, you may enlarge the mesh of an edge part side from the intermediate part of an up-down direction. Thus, a concrete frame with a stable concrete strength can be obtained with reduced rebound loss . Also, network-side frame 2 may be any one as long upper and lower sides are substantially shaped flat shape without protruding vertical lines is not limited to crimp wire mesh from upper and lower sides of the mold, for example, a vertical line A wire mesh or the like in which the intersections of the horizontal lines are partially or entirely welded can be used.
[0015]
FIG. 3 shows another embodiment of the present invention. This embodiment is provided with a protrusion for preventing slipping into a mold. The net-like side frame 2 has a shape in which the vertical line 3 does not protrude from the upper and lower edges over the entire length. In mold 1 made of such a network-side frame 2, in the present embodiment, fitted with a transverse rod 6 of a portion of the spacer 5 to be slidable in the vertical line 3 of the mesh side frame 2, its lateral bars 6 slide width Z a (play) was between horizontal lines 4 of the upper and lower pair. When the horizontal bar 6 is on the upper horizontal line 4d side (upper limit position of the spacer 5) (dotted line position in the figure), the entire spacer 5 is within the range of the vertical width of the reticulated side frame 2, and the upper end of the vertical bar 7 is It is below the upper edge of the side frame (uppermost horizontal line 4f), the lower end is above the lower edge of the side frame (lowermost horizontal line 4g), and the lower end of the vertical bar 7 is the lower end of the vertical line 3 (lowest position) No horizontal line 4g). Horizontal bar 6 is lower horizontal line 4e side when in the (spacer lower limit position of 5) (solid line position in FIG.), Under the base of the columns 7 from the lower end of the vertical line 3 (horizontal 4g lowermost position) Protruding. The projecting length is set to an appropriate length such as to be caught on a vegetation wire mesh laid on a natural ground. Note that all the spacers of the mold 1 may be slidable spacers 5 as described above , or only a part of the spacers (for example, spacers at both ends or one end) may be slidable. In this case, the other spacers are formed so as to be within the range of the vertical width of the mesh form 2.
[0016]
When folding and transporting the frame 1 for the frame , the spacer 5 is moved to the upper limit position. In this case, the mold 1 can be turned upside down and moved to the upper limit position by dropping the spacer 5 with its own weight. You may make it have some sliding resistance of the extent which it does not fall by its own weight, and it may be lifted by hand. As a result, when carrying, there are no protruding parts on the upper and lower sides of the mold, improving the handleability, simplifying the packaging, and greatly reducing the packaging material such as cardboard.
[0017]
At the time of construction of the frame, the spacer is moved to the lower limit position by its own weight (or by hand) by properly arranging the upper and lower sides and opening the mold 1. As a result, the lower end of the vertical bar 7 of the spacer protrudes from the lower edge of the reticulated side frame 2, so that when the vegetation wire net is laid on a natural ground, the vertical bar 7 is caught on these, and the work does not slip. Can be done smoothly.
[0018]
The range of play is determined so that the cover of the reinforcing bars installed in the legal frame can be appropriately secured at the lower limit position of the spacer 5. For this reason, the length of the play may be changed by adjusting the height of the horizontal bar on the lower side of the spacer 5 or changing the interval between the horizontal lines 4 of the mesh-like side frame 2. The shape of the spacer 5 is not limited to the shape of a cross beam with two vertical bars, but may be a letter with one vertical bar 7. Moreover, it is good also as a formwork which makes the center part of the upper horizontal bar 6 open, makes it the spacer which connected the free end side of the right and left horizontal bar to the vertical bar, and can arrange | position a lower reinforcing bar from the opening.
[0019]
FIG. 4 is an explanatory view of the shape of another embodiment of the present invention. In the figure, the reference numerals are the same as those in FIG . Law frame for formwork This 1 are those linked foldably superimposed with each other via a pair of mesh side frame 2,2 plurality of spacers 5 (the figure shows only one). Each mesh-like side frame 2 is a crimp wire mesh in which vertical lines 3 and horizontal lines 4 are woven in a lattice shape. As in the example of FIG. 1 described above, the upper and lower end portions of each vertical line 3 are bent or shortly cut, and do not protrude upward and downward from the upper side and lower side of the net-like side frame 2.
[0020]
Furthermore, in the embodiment of FIG. 4, the end of each horizontal line 4, as in the case of the vertical lines 3, (see section C details) by attaching vertical line 3 wound by folding, longitudinal lateral end portions It is configured not to protrude outward from the line 3. Therefore, the outer periphery of the reticulated side frame 2 is a straight line that is substantially smooth in the entire top, bottom, left, and right, and the ends of the vertical lines and horizontal lines that are not cut out do not protrude outward.
[0021]
The spacer 5 is, as in the example of FIG. 3 described above may be slidable relative to the vertical. Thus, when packing, the spacer 5 can be sandwiched between both mesh-like side frames 2 and 2 with the upper and lower ends not projecting, and the mold can be folded to make a simple packing. Thus, the spacer 5 can be slid so as to protrude below the lower edge of the reticulated side frame 2 and installed without sliding on the natural slope. In this case, if the spacer shape is vertically symmetric and is slidable in any direction up and down to protrude from the reticulated side frame, the up and down directionality of the mold frame is lost, and the handleability is further improved.
[0022]
【The invention's effect】
As described above, in the present invention according to claim 1, the upper end and the lower end of the vertical line are alternately bent and wound around the horizontal lines of the upper side and the lower side, respectively, and the end on the other end side from the upper side or the lower side. Since it is located inside, the following effects can be obtained.
(1) upper and lower sides Ri substantially planar der, and since part of hewn from the side frame does not project vertically, getting better handling properties during storage or during carrying, less packing material in good rather than packing can also easily. Also, Oite at the time of construction, without being caught by the concrete hose and work clothes, etc., to improve the workability.
(2) Further, the upper and lower ends of the vertical line are alternately wound around the horizontal line, so that the vertical line and the horizontal line are securely coupled to each other on the upper side and the lower side, so that the shape of the mold can be accurately maintained. In addition, the workability can be improved because the end on the other end side may be left uncut.
( 3 ) Moreover, since the upper side and the lower side have the same shape, a formwork for a legal frame that does not need to be confirmed at the site is possible, so that workability can be further improved .
( 4 ) Further , since the lower side of the side frame is flat, when it is installed on a slope, the bite into the natural ground is prevented and the necessary height is maintained, and a predetermined formwork cross-sectional area can be secured. Thus, there is no need to increase by replenishing the mold or after addition of the extra concrete, is improved workability there is no waste.
[0023]
According to the invention of claim 2, at the time of construction is that by projecting from the lower side of the mold the vertical bars of the spacer, it is possible to prevent slippage only scratching the lower end to the ground or lath metal gauze. And at the time of conveyance , the handling property in conveyance can also be aimed at by storing a spacer between the upper and lower edges of a mesh side frame .
[0024]
Furthermore, according to the third aspect of the present invention, the portion of hewn from all the outer peripheral edge of the upper and lower left and right ends of each horizontal line with vertical lines of the mesh side frame be included reticular side frame does not protrude, the operator Ya The handling is further improved because the object is not caught or damaged. Further, when the transportation time and carry, when the packing is folded formwork, it is not necessary to cover and protect the end portions of the net-side frame of cardboard or the like, corner simply by simply binding with string or a belt or the like, The packaging material is reduced and the packaging work is simplified.
