Abstract

<P>PROBLEM TO BE SOLVED: To provide a form panel which is constituted by fixing a reticulate object to a lattice body formed of wire rods and which prevents the reticulate object from being easily disengaged from the lattice body by a force and an impact, applied from the outside, a building form using the form panel, and a concrete foundation. <P>SOLUTION: The form panel is constituted by sandwiching the reticulate object 2 between the opposite lattice bodies 1 and 1a facing each other. The lattice bodies 1 and 1a are superposed on each other by being displaced in the axial direction of lateral wire rods 12 and 12a, so that each longitudinal wire rod 11a of the other lattice body 1a can be juxtaposed to each longitudinal wire rod 11 of one lattice body 1 in such a manner as to be adjacent or close to the axial direction of the lateral wire rods 12 and 12a. Thus, a part of the reticulate object 2 is sandwiched between the longitudinal wire rods 11 and 11a which are juxtaposed in such a manner as to be adjacent or close to each other, so as to be bent in a direction crossing the axial direction of the lateral wire rods 12 and 12a. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

The present invention relates to a formwork panel, an architectural formwork using the formwork panel, and a concrete foundation.
More specifically, a formwork panel configured by fixing a net-like object to a lattice body formed of a wire, in which the net-like object is not easily detached from the grid body due to an external force or impact, and It relates to the formwork for construction and the foundation made of concrete.
In addition, the formwork panel can be smoothly stretched, and the foundation surface after concrete placement can be constructed beautifully in a flat manner. Related to the basics.

  Generally, a building or a civil engineering structure is constructed on a concrete foundation as a foundation. Conventionally, as a concrete formwork used for making a foundation, a wooden plywood board has been used for reasons such as light weight and low cost.

  However, since the plywood corrodes in the ground, it is necessary to remove it after solidifying the concrete, which has been a factor in prolonging the construction period. Moreover, since the removed plywood was incinerated without being reused, valuable wood resources were wasted as a result, which was not preferable from the viewpoint of global environmental conservation.

Therefore, in recent years, as shown in, for example, Patent Document 1 (see FIG. 6), a formwork panel B using a wire mesh 5 has been used. The concrete formwork using this formwork panel B is buried in the ground together with concrete as it is called “discarded formwork”. Therefore, the construction period is shorter than the conventional method that required the removal work of plywood. Can be greatly shortened.
Japanese Patent No. 3090909

  FIG. 7 is a perspective explanatory view showing a method for manufacturing a formwork panel proposed in Patent Document 1. In FIG. As shown in FIG. 7, most of the currently used formwork panels B are constructed by welding a wire mesh 5 to a lattice body 4 formed of wire rods 41, 42, 43, 44. FIG. 8 is a schematic explanatory view showing a cross section corresponding to the II portion of FIG. 7 when assembled. For convenience of explanation, in FIG. 8, the welded portion 6 is marked with a round dot, and the horizontal wire 41 in the left-right direction is hatched.

  Then, as shown in FIG. 6, the formwork panel B transported to the site is bound to a beam reinforcement (not shown in the drawing) on the concrete surface C previously placed by a wire 71 or the like. A plurality are stretched so as to face each other with a required distance. Next, the required number of separators 72 are attached between the opposing formwork panels B and B so as to be bridged.

  When the attaching work of the separator 72 is completed, the concrete pipe laying work is usually completed by attaching the single pipe 73 to the upper edge side of the formwork panel. The concrete foundation is completed by placing and solidifying the concrete in the concrete formwork.

  However, as shown in FIG. 8, the conventional formwork panel proposed in Patent Document 1 simply fixes the wire mesh 5 to the lattice body 4 by welding. In addition, the wire mesh 5 is generally formed of a thin wire rod, and the wire rod may be melted and easily broken by the welding operation, so that excessive welding cannot be performed. For this reason, it cannot be said that fixing the wire mesh 5 to the wire rod is sufficient. For example, when the formwork panels are caught or collided during the assembly work of the moldwork, the wire mesh 5 may come off the wire rod, There was a risk that the part would dent.

  Further, when the end of the separator 72 (see FIG. 6) is locked to the wire rod of the formwork panel B, usually, a part of the wire mesh 5 is broken using a special tool with a sharp tip, A hole for passing the separator 72 is formed. However, if the wire mesh 5 is not sufficiently fixed to the wire rod, the wire mesh 5 itself may come off from the wire rod when the tool is hooked on the wire mesh to break it.

On the other hand, for example, in Patent Document 2, as shown in the partial enlarged cross-sectional view shown in FIG. 9, welding is performed in a state where the wire mesh 5 is sandwiched from the front and back sides by the vertical wire 81 and the horizontal wire 82 which are wire rods. It has been proposed to construct a frame panel C. According to this, since the metal mesh 5 is fixed in a state of being sandwiched from the front and back surfaces by the vertical wire 81 and the horizontal wire 82, the fixing strength of the metal mesh 5 with respect to the wire is considered to be somewhat improved.
Japanese Patent No. 3090909

  However, in the case described in Patent Document 2 (see FIG. 9), a portion where the vertical wire 81 and the horizontal wire 82 intersect each other is a portion where the vertical wire 81 and the horizontal wire 82 overlap each other and sandwich the wire mesh 5 (points). However, it is difficult to say that the strength is improved so much.

  Moreover, unlike the one described in Patent Document 1 (see FIG. 8) in which the wire mesh 5 is fixed in a wave shape by welding, the one described in Patent Document 2 (see FIG. 9) is arranged in the axial direction of the horizontal wire 82. On the other hand, the metal mesh 5 is stretched flat. For this reason, the wire mesh 5 is inferior in yield strength in the tensioning direction. For example, when a force is applied to the wire mesh 5 from a direction intersecting the tensioning direction of the wire mesh 5, the wire mesh 5 is linearly displaced toward the portion where the force is applied. Therefore, a dent is likely to occur in that portion.

As "grid" and "net" in the present invention, a formwork panel is formed with a formwork panel formed of the grid and the net, and mortars are poured into the formwork and filled. In addition, the type of the mortar is not particularly limited as long as it has a strength and a mesh size that are not easily deformed by the pressure of the mortar.
Examples of materials for grids (specifically, the wire constituting the grid) and nets include metals, plastics (fiber reinforced plastic (FRP), etc.), wood, combinations thereof, and other materials. Can do.
Specific examples of the net-like material include expanded metal, punching metal, turtle shell wire mesh, crimp wire mesh, lath and welded wire mesh.

  In addition, the term “wire” used in the present specification and claims is used as a broad concept including “rod”, “rebar”, and “steel wire”. There is no particular limitation.

  The terms “vertical wire” and “horizontal wire” used in the present specification and claims do not limit the direction of the wire during use. Therefore, the formwork panel can also be used so that the vertical wire is oriented horizontally or obliquely, or the horizontal wire is oriented vertically or obliquely.

(Work)
The formwork panel according to the present invention operates as follows.
(A) The formwork panel according to the present invention is configured by sandwiching a net-like material between a pair of opposing lattice bodies. And each 1st wire (vertical wire) of the other lattice body is arranged in parallel in the axial direction of the 2nd wire (horizontal wire) adjacent to or adjacent to each 1st wire (vertical wire) of one grid. In this way, a pair of grids are shifted in the axial direction of the second wire (horizontal wire) and overlapped so that part of the mesh is adjacent to or adjacent to each other between the first wires (vertical wires) arranged side by side. And is bent in a direction intersecting the axial direction of the second wire (horizontal wire).
Therefore, even when a force is applied to the mesh from a direction crossing the stretching direction of the mesh, the bent portion is caught by the first wire (vertical wire), and the mesh is directed to the portion where the force is applied. As a result, the dent is not easily formed.

(B) The above-described formwork panel is also used for the formwork panel formed by combining the wires formed in a lattice shape and facing each other and sandwiching the net-like material between the lattice bodies. Works in the same way. That is, at the place where the wire constituting the facing grid is parallel in the spreading direction, the mesh is bent at the place of the wire that is parallel and sandwiched between the wire, Even if force is applied to the mesh from a direction that intersects the direction in which the mesh is stretched, the bent part is caught by the parallel wires, and the mesh is displaced toward the part where the force is applied. As a result, it is difficult to form a dent in that portion.

(C) Each of the horizontal wire members of the opposing grid body facing each other with the net-like material sandwiched therebetween has the net-like material sandwiched between the vertical wire materials as described above and the opposing grid body Since the mesh is sandwiched between the horizontal wires, the mesh is fixed to the wire more firmly.

(D) For one grid body in which the net is fixed over the entire surface, the other grid body facing the net is fixed while being shifted essentially parallel to the direction in which the formwork panel is stretched. In addition, one of the lattice members protrudes in a direction opposite to the direction in which the other lattice member protrudes in a shifted manner. Thus, when a plurality of formwork panels are stretched to form a formwork for construction, a portion (connecting portion) where the formwork panels are overlapped is overlapped by superimposing the lattice parts that are shifted from each other. Essentially, the thickness of one formwork panel can be made so that both sides of the connected formwork panels are essentially flush.

(E) The formwork panel has connecting portions on both sides to be connected, and one of the connecting portions has one lattice body without the other lattice body and a net, and the other of the connecting portions has one lattice. When the form panel is connected, the connecting part has a structure in which the net is sandwiched between the opposing lattices, and the connected formwork Even if both sides of the panel are essentially flush with each other, they operate in the same manner as the above-described formwork panel.

The present invention has the above-described configuration and has the following effects.
(A) According to the formwork panel according to the present invention, even when a force is applied to the mesh from a direction intersecting the stretching direction of the mesh, the bent portion is the first wire (vertical wire, in parallel). The mesh is not easily displaced in the direction in which the force is applied, and as a result, it is difficult to form a dent in that portion. Thus, according to the formwork panel concerning this invention, it has sufficient intensity | strength that a net-like object does not remove | deviate from a lattice body easily by the force and impact which were received from the outside.

(B) When each horizontal wire of the opposing lattice body is face-to-face with the mesh sandwiched therebetween, the mesh can be more firmly fixed to the wire.

(C) One grid body on which the net-like object is fixed over the entire surface is fixed by shifting the other opposite grid body in a direction essentially the same as the direction in which the formwork panel is stretched. When forming a building formwork by stretching a plurality of adjacent formwork panels while overlapping both ends, the overlapping part of the formwork panel is essentially the thickness of one formwork panel and connected. Both sides of the formed formwork panel can be essentially flush.
Accordingly, when the formwork panels are stacked, the formwork panel can be stretched linearly, unlike the case where the overlapped portion has a thickness corresponding to two formwork panels.
Further, since the formwork panels may be overlapped with each other using the shifted portion as a guide, the overlapping position can be easily determined, and the tensioning operation can be performed smoothly.
Furthermore, since the formwork for construction can be formed by straightly stretching the formwork panel without causing a step, the surface of the foundation after placing the concrete can be constructed beautifully.

(D) The formwork panel has connecting portions on both sides to be connected, one of the connecting portions has one lattice body and the other lattice body and a net, and the other of the connecting portions is one lattice. When the formwork panel is connected, the connecting part has a structure in which the net is sandwiched between the facing grids, and the other grid and the net are not connected. Since both sides of the formwork panel can be essentially flush with each other, the same effect as the above formwork panel can be obtained.

(E) It is possible to obtain a building formwork and a concrete base using a formwork panel having the above-described effects.

  The invention will be explained in more detail on the basis of an embodiment shown in the drawing.

FIG. 1 is a partially enlarged explanatory view showing a first embodiment of a formwork panel according to the present invention,
FIG. 2 is an exploded perspective view for explaining a method for manufacturing a formwork panel,
FIG. 3 is a partially enlarged explanatory view for explaining a method for manufacturing a form panel, and shows a part of a cross section corresponding to the II-II portion of FIG. 2 when assembled.
In FIG. 3, the horizontal wires 12 and 12 a are hatched so that the positional relationship between the wire mesh 2 and the horizontal wires 12 and 12 a can be clearly understood.

  As shown in FIG. 2, the formwork panel A1 shown in FIG. 1 has a pair of lattices formed by intersecting a vertical wire 11 (11a) as a first wire and a horizontal wire 12 (12a) as a second wire. The body 1 (1a) is configured by welding with a wire net 2 that is a net-like material sandwiched therebetween.

  In addition, although the lattice body 1 and the lattice body 1a are the same shapes, the different code | symbol (1 and 1a) is attached | subjected for convenience of explanation. The same applies to the vertical wire 11 (11a) and the horizontal wire 12 (12a) which are constituent members.

  The metal mesh 2 has flexibility, flexibility, or deformability. Specifically, the wire mesh 2 uses expanded metal.

  In the lattice bodies 1 and 1a, a plurality of linear wires 11 (11a) arranged in parallel at equal intervals are arranged at right angles to (intersect) linear wires 12 (12a) arranged in parallel at equal intervals. ) Welded wire mesh is used that is assembled in a well beam and electrically welded at the intersection of each of the wires 11 and 12 (11a and 12a). For convenience of explanation, in FIG. 2, the wire disposed from the lower left to the upper right is defined as the vertical wire 11 (11a), and the wire disposed from the upper left to the lower right is defined as the horizontal wire 12 (12a).

  Then, as shown in FIG. 2, the pair of lattice bodies 1 and 1a are opposed to each other with the wire mesh 2 sandwiched therebetween. In that case, each grid | lattice body 1 and 1a is arrange | positioned so that the vertical wire 11 and 11a may face inside (wire-mesh 2 side).

  Next, as shown in FIGS. 3 (a) to 3 (b), each vertical wire 11 of one grid 1 is connected to each vertical wire 11a of the other grid 1a in the axial direction or length of the horizontal wires 12 and 12a. The pair of lattice bodies 1 and 1a are shifted in the axial direction of the horizontal wires 12 and 12a so as to be arranged adjacent to or adjacent to each other in the direction. And a required location (the part etc. which the wire of each grid | lattice body 1 and 1a overlapped) is welded, and the metal-mesh 2 is fixed to the grid | lattice bodies 1 and 1a.

  In this way (see FIG. 1), the vertical wire members 11 and 11a of the opposing lattice members 1 and 1a are shifted in the axial direction of the horizontal wire members 12 and 12a, and the horizontal wire members of the lattice members 1 and 1a. 12 and 12a are overlapped and fixed in a state where the metal mesh 2 is sandwiched therebetween.

If it does in this way, as shown in FIG.3 (b), a part of metal-mesh 2 will be inserted | pinched between the adjacent vertical line | wires 11 and 11a arranged in parallel, and the axis line of the horizontal line | wires 12 and 12a It will be in a state of bending in a direction that intersects the direction.
In other words, at the place where the vertical wire members 11 and 11a constituting the opposing lattice bodies 1 and 1a are arranged in parallel in the spreading direction, the wire mesh 2 is bent at the place of the vertical wire members 11 and 11a arranged in parallel. It is sandwiched between the vertical wires 11 and 11a.
Thereby, the wire mesh 2 as a whole is in a state of undulating in a wave shape. Hereinafter, the bent portion is referred to as a curved portion 13 for convenience of explanation.

  In addition, the manufacturing method of formwork panel A1 is not limited to the above-mentioned thing, For example, it does not have any trouble in pinching | interposing the metal mesh 2 to the one grid | lattice body 1a previously (for example, a pair of grid | lattice bodies 1 and 1a). After the portion is welded and fixed, the other lattice body 1 may be overlapped and welded.

  Further, as shown in FIG. 1, in the present embodiment, the horizontal wires 12 and 12a of the opposing lattice bodies 1 and 1a are in positions that overlap, but the positions of the horizontal wires 12 and 12a are shifted so as not to overlap. Formwork panels can also be constructed.

  Further, in this embodiment, a lattice member is used in which wires are arranged at right angles. However, the present invention is not limited to this, and the wires are obliquely assembled so that the mesh has a rhombus shape. A configured grid can also be used.

(Work)
The operation of the formwork panel A1 according to this embodiment will be described while comparing with the conventional formwork panel C described in Patent Document 2 (see FIG. 9).

In the case described in Patent Document 2 (see FIG. 9), the portion sandwiching the wire mesh 5 is only the portion where the vertical wire 81 and the horizontal wire 82 intersect.
On the other hand, in the present embodiment, as shown in FIG. 1, the wire mesh 2 is sandwiched between the horizontal wires 12 and 12a of the opposing lattice bodies 1 and 1a (the horizontal wire 12a on the back side is hidden and cannot be seen). As shown in FIG. 3 (b), the wire mesh 2 is sandwiched between adjacent or adjacent vertical wires 11, 11a. That is, in this embodiment, since the wire mesh 2 is sandwiched from both sides by the entire wire arranged in a lattice shape, the wire mesh 2 is firmly fixed to the wire as compared with the conventional wire.

  And as shown in FIG.3 (b), a part of wire mesh 2 is pinched | interposed between the adjacent vertical line | wires 11 and 11a juxtaposed adjacently, and cross | intersects the axial direction of the horizontal line | wires 12 and 12a. The bent portion 13 is formed by bending in the direction. Therefore, unlike the conventional case, even when a force is applied to the wire mesh 2 from the direction intersecting with the direction in which the wire mesh 2 is stretched, the bent portion 13 is caught by the vertical wires 11 and 11a and the wire mesh 2 is moved in the stretch direction. As a result, it is difficult to come off, and as a result, it is difficult to form a recess in a portion where force is applied. Thus, the formwork panel A1 according to the present embodiment has a sufficient strength against an external force and an impact on the wire mesh 2 in particular.

  And, at the time of enforcement, the formwork panel A1 transported to the site is similar to the conventional construction method (see FIG. 6), in the beam arrangement on the concrete surface C previously placed (not shown in the drawing), etc. A plurality of cables are stretched so as to face each other with a required distance while being bound by the wire 71. Next, the separator 72 is attached so as to be bridged between the opposing formwork panels A1 and A1.

  The orientation of the formwork panel A1 to be stretched may be such that the vertical wires 11 and 11a are in the vertical direction as shown in FIG. 1, or the horizontal wires 12 and 11a are reversed 90 degrees from the state of FIG. You may use so that 12a may become an up-down direction. Moreover, the surface to be opposed may be either the front surface or the back surface.

  When the work for attaching the separator 72 is completed, the concrete pipe laying work is usually completed by attaching the single pipe 72 to the upper edge side of the formwork panel A1. The concrete foundation is completed by placing and solidifying the concrete in the concrete formwork.

FIG. 4 is a partially enlarged explanatory view showing a second embodiment of the form panel according to the present invention and showing an overlapping portion of the form panel.
FIG. 5 is a partially enlarged explanatory view showing an overlapped portion when the end sides of the formwork panel according to the first embodiment shown in FIG. 2 are overlapped and joined.

  In FIGS. 4 and 5, the horizontal wires 12 and 12a are hatched so that the positional relationship between the formwork panels A1, A2 and A3 can be clearly understood. Further, the two formwork panels A2 and A3 shown in FIG. 4 have the same shape, but are indicated by different symbols (A2 and A3) for convenience of explanation.

  Of the operations of the second embodiment, the same operations as those described in the first embodiment are not described. Moreover, about the location equivalent to the location shown in Example 1, description is abbreviate | omitted and difference is mainly demonstrated.

When forming a concrete formwork by stretching a plurality of formwork panels, both end portions of adjacent formwork panels that are connecting portions are overlapped.
For example, as shown in FIG. 5, when the formwork panels A1 and A1 described in the first embodiment are overlapped, the overlapped portion becomes the thickness of two formwork panels. For this reason, if the next formwork panel (not shown) superimposed on the right side of the formwork panel A1 superimposed on the outside (for example, the upper side in FIG. 5) does not overlap the inside of the previous formwork panel A1, the formwork The extending positions of the panels A1 and A1 are shifted one after the other. Therefore, if the formwork panel A1 is not stretched alternately on the inner side, the outer side, and the edge side, the formwork panel A1 can not be stretched linearly, and the workability is complicated. It takes time and effort.

  Therefore, in this embodiment, as shown in FIG. 4B, the formwork panels A2 and A3 are formed so that the portion (connecting portion) where the formwork panels overlap is essentially the thickness of one formwork panel. Is configured.

  That is, like the formwork panel A2 shown on the left side of FIG. 4 (a), the other lattice body 1 opposed to the other lattice body 1a to which the wire mesh 2 is fixed over the entire surface is the formwork panel A2. Is shifted essentially in parallel with the direction in which it is stretched (left side in FIG. 4).

  As a result, in the formwork panel A2 shown on the left side of FIG. 4A, one grid body 1a protrudes to the right end side, and the other grid body 1 shifts to the left end side (FIG. 4A (Like the formwork panel A2 shown on the right side).

  In other words, the formwork panels A2 and A3 have connecting portions on both sides to be connected, and one of the connecting portions does not have one lattice body 1 but has the other lattice body 1a and the net 2 and The other has a configuration in which one lattice body 1 is provided and the other lattice body 1a and the net 2 are not present.

  Therefore, as shown in FIG. 4 (b), overlapping portions that are shifted from each other are overlapped, so that the overlapped portions are essentially made as thick as one sheet of the form panel, and the connected forms Both sides of panels A2 and A3 can be essentially flush.

In this manner, when the formwork panels are stacked, the formwork panels A2 and A3 can be stretched linearly, unlike the case where the overlapped portion has a thickness corresponding to two formwork panels.
In addition, since the formwork panels A2 and A3 may be overlapped with each other using the shifted portion as a guide, the overlapping position can be easily determined, and the tensioning operation can be performed smoothly.
Furthermore, since the formwork panel for construction can be formed by linearly stretching the formwork panels A2 and A3 without causing a step, the surface of the foundation after placing the concrete can be beautifully constructed flat.

  Other operations and effects are substantially the same as those of the first embodiment described above, and thus the description thereof is omitted.

  Note that the terms and expressions used in this specification are merely explanatory and are not restrictive, and do not exclude terms and expressions equivalent to the above terms and expressions. The present invention is not limited to the illustrated embodiment, and various modifications can be made within the scope of the technical idea.
