Description

  The present invention provides a construction object surface and a grid-like body when constructing a grid-like body composed of vertical and horizontal strips in a grid shape, such as a welded wire mesh or a net-like fence embedded in concrete. The present invention relates to a spacer for providing a gap between and a lattice-like body provided with a spacer in advance.

  When placing concrete to construct a structure such as a floor of a building, in order to increase the strength of the structure and prevent cracks from occurring in the structure, a plurality of welded wire meshes are provided in the concrete. It is buried.

  FIG. 20 is an explanatory view for explaining a conventional method for constructing a welded wire mesh, in which WM is a welded wire mesh. The welded wire mesh WM has a plurality of vertical strips W1, W1,... And horizontal strips W2, W2,... Arranged in a grid, and the vertical strips W1, W1,. The part where ... intersects is fixed to each other by welding.

  A mold (not shown) is erected around the construction target area, and a plurality of welded metal meshes WM, WM,. At this time, adjacent edges of the welded wire meshes WM and WM overlap each other by a plurality of grids (1 grid in FIG. 20). Next, the welding wire meshes WM, WM,... Are lifted in order, and as shown in FIG. 20, spacers 30, 30,... Such as blocks are interposed between the construction target surface and the welding wire meshes WM, WM,. The welded wire mesh WM, WM,... Is placed on the spacers 30, 30,. As described above, by holding the welding wire meshes WM, WM,... On the spacers 30, 30,..., The welding wire meshes WM, WM,.

  In order to prevent mutual misalignment from occurring in the overlapping portion of adjacent welded wire meshes WM, WM, for example, even when stepped on by a worker working on the welded wire mesh, The overlapping welded wire meshes WM and WM are bound to each other by the binding materials B, B,. In this way, after the construction to the welded wire mesh WM, WM,... Is completed in the construction target area, the concrete is poured into the mold to a predetermined depth where the welded wire mesh WM, WM,. Level the surface.

  However, since the welding wire meshes WM, WM,... Are merely placed on the spacers 30, 30,..., The welding wire meshes WM, WM,. When the deviation occurs, the position of the spacers 30, 30,... Arranged in the portion has to be adjusted again. Therefore, the following spacer is disclosed in Patent Document 1 described later.

  FIG. 21 is a perspective view showing how the spacer disclosed in Patent Document 1 is used. The spacer 31 is formed by bending a metal wire having a diameter of about 5 to 6 mm, and is formed between the two rising portions 131c and 131c raised at a predetermined distance and both the rising portions 131c and 131c. An iron wire support portion 131g for supporting an iron wire constituting the welded wire mesh, and placement portions 131b and 131b that are horizontally bent from the lower ends of both rising portions 131c and 131c and placed on the deck plate DP are provided. Yes. In addition, the iron wire support 131g has an arcuate shape that curves and rises from the lower lateral portions 131d and 131d extending in the horizontal direction from the upper ends of both rising portions 131c and 131c, and the lower lateral portions 131d and 131d. It has the part 131e, 131e and the horizontal upper side part 131f which connects between the upper ends of both arc-shaped parts 131e, 131e, and has made the spiral shape flat in a side view. Here, the inner dimension between the lower lateral portions 131d, 131d and the upper lateral portion 131f is larger than the outer diameter of the iron wire constituting the welded wire mesh.

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

  However, in such a conventional spacer 31, the operation of inserting the iron wire of the welding wire WM into the iron wire support portion 131g of the spacer 31 is the same as before, with each of the welding wire meshes WM, WM, Since the worker has to lift up ..., there is a problem that it takes a long time to attach the spacer 31 to the iron wire of the welded wire mesh WM in addition to forcing the worker to work hard. On the other hand, by inserting the iron wire constituting the welded wire mesh WM into the spiral iron wire support 131g, the spacer 31 follows the movement of the welded wire mesh WM thereafter, but the spacer 31 is fixed to the welded wire mesh WM. Therefore, when the position of the welded wire mesh WM is adjusted due to a shift in the installed welded wire mesh WM, the iron wire inserted into the iron wire support portion 131g of the spacer 31 has both lower lateral portions 131d and 131d. In such a case, the portion of the welded wire mesh WM to which the spacer 31 is attached must be lifted again and the spacer 31 must be readjusted.

In the case where a plurality of welded wire meshes having spacers SP1 attached in advance are transported in a stacked manner, as shown in FIG. 4, the vertical strip material or the horizontal strip material constituting one or more laminated welded wire meshes are used as the spacer SP1. Since it can be made to fit in side part 11Bbg, 11Bg, the bulkiness of each laminated welded wire mesh can be made lower.

  On the other hand, the second frame member 12B includes an inverted U-shaped second main body 12Ba formed by arranging rectangular legs in parallel with each other. Both leg portions constituting the second main body 12Ba are formed as contact portions 12Bb and 12Bb that are brought into contact with the construction target surface, and outer portions of the both contact portions 12Bb and 12Bb are projected from the second main body 12Ba. The ceiling of the protruding portion of the contact portion 12Bb extends to the middle position of the second body 12Ba, and a second notch is provided between the protruding portion of the contact portion 12Bb and the second body 12Ba. The portions 32 and 32 are provided to the appropriate depth along the side edges of the second main body 12Ba. The width of the second cut portions 32 and 32 is slightly larger than the thickness of the first frame member 11B, and the first cut portions 31 and 31 of the first frame member 11B are incorporated in the second cut portions 32 and 32. Thus, the first frame member 11B and the second frame member 12B are fixed in a cross beam shape. The first main body 11Ba constituting the first frame member 11B and the second abutting portion 12Ba constituting the second frame member 12B are at a height position where the welding wire mesh to which the spacer SP1 is attached is separated from the construction target surface. It also functions as a carrying part for carrying.
