Further, the iron wire supporting portion 131g has an arc shape which is curved and stood up from the lower sideward portions 131d and 131d extending horizontally from the upper ends of the both rising portions 131c and 131c and the lower side portions 131d and 131d. It has a portion 131e, 131e and a horizontal upper side portion 131f connecting between the upper ends of both the arc-shaped portions 131e, 131e, and has a flat spiral shape in a side view. Here, the inner dimension between the lower side portions 131 d and 131 d and the upper side portion 131 f is larger than the outer diameter of the iron wire forming the welded wire mesh.

  In such a spacer 31, the welding wire mesh WM laid on the deck plate DP is lifted, the iron wire constituting the welding wire mesh WM is inserted into the spiral iron wire support portion 131g, and the welding is performed in that state. By lowering the wire mesh WM, the mounting portions 131b and 131b of the spacer 31 are brought into contact with the deck plate DP, and the spacer 31 is erected on the deck plate DP. At this time, the iron wire inserted into the iron wire support portion 131 g is carried on both lower side facing portions 131 d and 131 d of the spacer 31.

FIG.5 and FIG.6 is the top view and front view which show the welding-wire net | network as a grid | lattice-like body based on this invention, The spacer part mentioned later is integrated in several longitudinal bars and horizontal bars. In both figures, parts corresponding to parts shown in FIGS. 1 to 4 are given corresponding numbers.

  As shown in FIGS. 5 and 6, the welding wire mesh (lattice-like body) WM1 includes a plurality of longitudinal strips W1, W1,... Arranged in parallel with each other at a predetermined distance. A plurality of horizontal strips W2, W2,... Intersecting with the longitudinal strips W1, W1,. A plurality of grids M, M,... Are formed by the longitudinal members W1, W1,... And the lateral members W2, W2,. A wire mesh main body (lattice-like main body) wm is formed by the longitudinal bars W1, W1,... And the horizontal bars W2, W2,. In the welded wire mesh WM1 shown in FIGS. 6 and 7, the longitudinal dimensions of the longitudinal strips W1, W1,... Are shorter than the longitudinal dimensions of the transverse strips W2, W2,.

Although the case has been described, the present invention is not limited to this, and an appropriate number of spacer portions sp1, sp1,... May be incorporated at appropriate positions of the wire mesh main body wm. For example, when the dimension of the wire mesh main body wm is 1 m × 2 m, it is preferable to incorporate the spacer portions sp1 and sp1 at the center positions of both long sides in addition to the four corners of the wire mesh main body wm.

  7 is a partially enlarged perspective view of a portion incorporating the spacer portion sp1 of the welding wire mesh WM1 shown in FIGS. 5 and 6, and FIG. 8 is a perspective view of the spacer portion sp1 shown in FIG. In the figures, parts corresponding to parts shown in FIGS. 5 and 6 are given the same reference numerals.

  As shown in FIG. 8, the spacer portion sp1 includes a pair of first frame members 111 and 111 formed by forming a bar material into an inverted convex shape, and a pair of short rod-like second frame members 112 and 112. The first frame members 111 and 111 and the second frame members 112 and 112 are fixed in the form of parallel crosses.

  As in the previous case, the first frame member 111 is a main body formed in a U-shape as a whole, with the both end portions of the contact portion 111b in the shape of a straight line to be abutted against the construction target surface upstanding. Arm portions 111d, 111d in the form of straight lines are extended at both ends of the main body 111a in a posture substantially parallel to the contact portion 111b. The two first frame members 111 and 111 are arranged parallel to each other at a distance from each other, and are circumferential surfaces of the two pairs of opposing arm parts 111 d, 111 d, 111 d and 111 d, ie, the first frame member 111. Second frame members 112 and 112 are provided at positions opposite to the contact portions 111 b and 111 b of 111, respectively. In addition, although the case where the linear contact portion 111b is provided is shown in the present embodiment, the present invention is not limited to this, and an appropriate shape such as an uneven shape or a wavy shape may be used.

  Then, as shown in FIG. 7, the rising portions 111 c and 111 c and the contact portions 111 b and 111 b are provided in the appropriate grids M of the wire mesh main body wm for both first frame members 111 and 111 of the spacer portion sp 1.

In addition, both vertical frame members W1, W1 or horizontal steel strips W2, W2 (in the case shown in FIG. 7) are in contact with each other and both end portions of both second frame members 112, 112 are in contact with each other. A circumferential surface of W1, W1), the contact portion 11b, and 111b so as to contact the opposite position, Aru incorporates a spacer portion sp1 wire mesh body wm.

  Here, the outer dimension between the two first frame members 111 arranged in parallel is the inner dimension between adjacent longitudinal bars W1 and W1 constituting the mesh M incorporating the spacer portion sp1, or adjacent to each other. It is slightly shorter than the inner dimension between the horizontal bars W2, W2. As a result, as shown in FIG. 8, both the first frame members 111, 111 are closely packed in the adjacent longitudinal bars W1, W1 constituting the mesh M or in the adjacent horizontal bars W2, W2. Since it is inserted, it is prevented that the spacer part sp1 shifts | deviates to the direction orthogonal to the longitudinal-row material W1, or the direction orthogonal to the horizontal-strip material W2.

  The dimension from the tip of one arm portion 111d of the first frame member 111 to the tip of the other arm portion 111d is the distance between adjacent horizontal strip members W2 and W2 constituting the mesh M incorporating the spacer portion sp1. The inner size is larger than the inner size between adjacent longitudinal bars W1 and W1. Furthermore, the length dimension of the second frame members 112, 112 is the inner dimension between adjacent longitudinal bars W1, W1 constituting the mesh M incorporating the spacer portion sp1, or the transverse bars W2, W2 adjacent to each other. It is larger than the inside size. As a result, both the first frame members 111, 111 and both the second frame members 112, 112 can be incorporated into the wire mesh main body wm as described above.

  On the other hand, the outer dimensions between the second frame members 112 and 112 are the inner dimensions between adjacent horizontal bars W2 and W2 constituting the mesh M incorporating the spacer portion sp1, or the vertical bars W1 and W1 adjacent to one another. It is slightly shorter than the inner dimension between them. As a result, as shown in FIG. 8, both the second frame members 112, 112 are closely packed in the adjacent horizontal bars W2, W2 constituting the grid M or in the adjacent vertical bars W1, W1. Since it is inserted, it is prevented that the spacer part sp1 shifts | deviates to the direction orthogonal to the horizontal strip material W2, or the direction orthogonal to the longitudinal strip material W1.

  As in the case of the spacer SP shown in FIG. 2, the outer dimension between the first frame members 111 and 111 is the same as the inner dimension between adjacent longitudinal bars W1 and W1 described above, or adjacent to each other. And the outer dimension between the second frame members 112 and 112, the inner dimension between the adjacent horizontal strips W2 and W2, or the adjacent vertical dimension It may be shorter than the inner dimension between the strip members W1 and W1. As a result, the spacer portion sp1 can be shifted in the vertical and horizontal directions within the grid M of the wire mesh main body wm. By the way, although a plurality of welding wire mesh WM1, WM1, ... concerning this form are manufactured in a manufacturing plant, when transporting by a truck etc. from this manufacturing plant to a construction object site, a plurality of welding wire mesh WM1, WM1, WM1 on a loading platform ... load each other. At this time, the spacer portions sp1, sp1,..., Sp1, sp1,..., Sp1, sp1, sp1 of the welding wire mesh WM1, WM1 in the upper and lower welding wire meshes WM1, WM1 by shifting the spacer portion sp1 in the longitudinal and lateral directions The positions of ... can be made different from each other. By this, the gap between the upper and lower welding wire meshes WM1, WM1 can be narrowed as much as possible, and the transport density of the welding wire meshes WM1, WM1 can be improved.

  In such a welding wire mesh WM1, the spacer portions sp1, sp1,... Are respectively incorporated at appropriate positions of the wire mesh main body wm, so the welding wire meshes WM1, WM1,. The installation work of the welding wire mesh WM1, WM1, ... and the spacer parts sp1, sp1, ... is completed simply by installing, and the work of lifting the welding wire mesh to install the spacer after installing the welding wire mesh as in the prior art is omitted. can do. In addition, even if the welding wire meshes WM1, WM1,... Are deviated and the positions of the welding wire meshes WM1, WM1,. Since the sp1,... are incorporated, no displacement occurs in the spacer portions sp1, sp1,. Therefore, the laying work of the welding wire mesh WM1, WM1,... Can be completed in a short time without forcing the worker to do heavy work. Furthermore, in the present welding wire mesh WM1, since the spacer portions sp1, sp1,... Are incorporated in advance in the wire mesh main body wm, the work of fixing the spacer SP to the welding wire mesh WM as described above becomes unnecessary and work efficiency is further improved. It can be done.

Third Embodiment of the Invention
FIG. 9 is a perspective view showing an example of a spacer according to a third embodiment of the present invention, in which 11B shows a first frame member and 12B shows a second frame member. As shown in FIG. 1, in the present spacer SP1, a pair of first frame members 11B and 11B formed as described later using a plate material and a pair of second frames similarly formed as described later using a plate material The members 12B and 12B are connected in plan view in the form of a parallel cross.

  The first frame member 11B is, as shown in FIG. 1, substantially buffalo-headed with both corners hanging. That is, the first frame member 11B has a first main body 11Ba provided with rectangular legs 11Bf and 11Bf arranged in parallel with each other at a predetermined distance, and from the bottom of both legs 11Bf and 11Bf to the legs The first cut portions 31 and 31 are respectively provided on center lines in the width direction of the legs 11Bf and 11Bf between mid-longitudinal positions of the portions 11Bf and 11Bf. The width dimension of the first cut portion 31 is slightly larger than the thickness of the second frame member 12B, and the second frame member 12B can be incorporated into the first cut portion 31.

  The ceiling portion of the first frame member 11B is a rectangular recess, whereby the weight of the first frame member 11B is reduced. On the other hand, the bottom of the first frame member 11B, and the portion between the two legs 11Bf and 11Bf is in the form of a circular arc convex in the direction separating from that portion, whereby both legs 11Bf of the first frame member 11B , 11 Bf have a high structural strength.

  On the other hand, arm portions 11Bd and 11Bd, which are tapered from the shoulders of the first main body 11Ba, respectively, gradually decrease in height as they are separated from the first main body 11Ba are projected, and both arm portions 11Bd, Following the inclination of 11Bd, hook-shaped fixing portions 11Be and 11Be are extended in a posture in which the opening of the hook is directed to the ceiling side of the first main body 11Ba.

Thus, the tip end portions of the end faces ST, ST are engaged with the circumferential surface of the longitudinal wire or the circumferential surface of the transverse wire of the welding wire mesh.

  Further, the side portions 11Bg and 11Bg between the arm portion 11Bd and the side edge of the first main body 11Ba are made to fit one or more longitudinal or horizontal strips constituting another welded wire mesh in the depth direction. The bottoms of the side portions 11Bg and 11Bg are curved to have a curvature according to the longitudinal or lateral bars. In the case of stacking and transporting a plurality of welding wire nets to which the spacer SP1 is attached in advance, as shown in FIG. Since the side portions 11Bbg and 11Bg can be inserted, the bulkiness of each of the laminated welded wire mesh can be further reduced.

  On the other hand, the second frame member 12B includes an inverted U-shaped second main body 12Ba in which rectangular legs are disposed in parallel to each other. The two leg parts constituting the second main body 12Ba are configured as contact parts 12Bb and 12Bb to be brought into contact with the surface to be constructed, and the outer parts of both contact parts 12Bb and 12Bb are made to project from the second main body 12Ba. The ceiling of the projecting portion of the abutting portion 12Bb extends to about the center position of the second main body 12Ba, and a second notch is formed between the projecting portion of the abutting portion 12Bb and the second main body 12Ba. The portions 32, 32 are provided to an appropriate depth following the side edge of the second main body 12Ba. The width dimension of the second cut portions 32, 32 is slightly larger than the thickness of the first frame member 11B, and the first cut portions 31, 31 of the first frame member 11B are incorporated in the second cut portions 32, 32. Thus, the first frame member 11B and the second frame member 12B are fixed in the form of parallel crosses. The first main body 11Ba constituting the first frame member 11B and the second contact portion 12Ba constituting the second frame member 12B are at a height position at which the welding wire mesh to which the spacer SP1 is attached is separated from the target surface It also functions as a carrying part to carry.
