Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building such as a mud composed of earth and wall soil mainly composed of water, and a ceiling, floor, wall and pillar composed of concrete mainly composed of cement and water. Inner / outer surface, road surface and road shoulder (slope), viaduct outer surface, ground ground, underdrain and waterway outer surface, etc.

[0002]

2. Description of the Related Art These building interior and exterior surfaces, road surfaces, slopes, ground,
When a waterway surface (these are referred to as civil engineering and construction laminates in the present invention) is formed by a fluid composition having a solidifying property such as mud or concrete (hereinafter simply referred to as fluid composition), the civil engineering In order to secure the strength of the building laminate, a net-like structure such as a wire mesh or mesh wire mesh is embedded inside.

[0003]

These wire meshes, mesh wire meshes, etc., which have been conventionally used, are, first of all, heavy and difficult to carry because they are made of metal, and are difficult to bend. In the case of the civil engineering and construction laminate, a special support frame is required. Secondly, since it is a flat plate, when the civil engineering and construction laminate is thick, insert a spacer or support it with auxiliary bars. Since it is necessary to stack several sheets at the same time, it is difficult to use them, and it is not possible to construct the civil engineering and construction laminate efficiently. And at the construction site of civil engineering and building laminates, it is practically impossible to stack many heavy wire meshes or mesh wire meshes with a certain gap, so using them, It cannot be reinforced in the thickness direction.

[0004]

SUMMARY OF THE INVENTION Therefore, the present invention provides a net-like structure which is lightweight and flexible and can be reinforced in the thickness direction of a civil engineering and construction laminate without any trouble in transportation and construction, thereby making the civil engineering and construction excellent in durability. The purpose is to make it possible to construct a laminate easily.

[0005]

That is, a civil engineering and construction laminate 17 according to the present invention is formed by a solidified fluid composition 11, and a first mesh 12 and a second mesh 13 are connected by a connecting material 15. In addition, a multi-mesh core material 16 having a void layer 14 having a constant thickness is embedded between the first mesh 12 and the second mesh 13, and the void 14 is filled with the fluid composition 11. Is the first feature. A second feature of the present invention is that, in addition to the above first feature, at least one of the first mesh 12 and the second mesh 13 of the multi-mesh core material 16 has the void layer 1
4 has an opening 18 with an inner diameter of 1 mm or more, leading to
The total internal area of all openings (18) existing per 1 m ^{2 of} the mesh 12 or the second mesh 13 is 0.1.
m ² or more, and the multi-mesh core material 16 is composed of yarns such as fibers and metals.

As used herein, the term "civil engineering building laminate" means the interior and exterior surfaces of buildings such as ceilings, floors, walls, columns, road surfaces and road shoulders (slopes), viaduct exterior surfaces, and ground surfaces. , Means what constitutes the outer surface of a culvert or aqueduct. Further, the "fluid composition" is a concrete composition containing cement and water as essential components, and a mud composition containing soil and water as essential components, having fluidity and moisture content. Means that can be solidified by evaporation or hydration reaction of the composition,
Various aggregates such as sand, gravel, stones, styrofoam pieces, and grass, and binders and adhesives such as CMC and PVA are appropriately mixed therein. The inner diameter of the openings 18 of the first mesh 12 and the second mesh 13 is set to 1 mm or more, and all the openings (1 m ² existing per 1 m ^{2 of} the first mesh 12 and the second mesh 13 (1
The total internal area of 8) is set to 0.1 m ² or more so that the fluid composition 11 can flow into the void layer 14 through the opening 18.

When the multi-mesh core material 16 is composed of fiber yarns, the fiber yarns may be synthetic fibers such as polypropylene fibers and aramid fibers, as well as corrosion resistant monofilaments such as carbon fibers, glass fibers and metal fibers. It is used as a single yarn or several yarns are aligned or twisted, and the thickness thereof is appropriately set.

In this case, the multi-mesh core material is used as a warp knitting machine (so-called double Raschel warp knitting machine) or a loom (so-called double moquette loom or double wilton carpet loom) used for manufacturing pile fabrics. It can be manufactured by using a pile loom. That is, in the double Raschel warp knitting machine, the ground chain stitch row 21 formed by arranging the ground warp threads 19 in parallel is connected by the insertion thread 22 and the pile thread ( After knitting the pile fabric raw fabric (16) connected by 15), the pile yarn (15) is cut (so-called center cut) between the upper fabric and the lower fabric to form a cut pile. Two pile fabrics are manufactured at the same time. Further, in the double pile loom, a pile fabric original fabric having a double structure in which a ground yarn (15) is connected between an upper cloth and a lower cloth, which are woven in a double manner by interlacing ground warp threads and ground weft threads ( In the same manner as in the case of the double Raschel warp knitting machine, 16) is subjected to center cutting of the pile yarn to produce two upper and lower cut pile fabrics. However, in the present invention, the double pile fabric original fabric in which the pile yarn (15) is not center cut is used as it is as the multi-mesh core material 16.

Therefore, the "connecting material" in that case corresponds to the pile yarn of the double pile fabric original fabric, but the present invention does not center cut it. Since the connecting material does not form a pile as described above, it is referred to as a "connecting material" in the present invention, not as a "pile thread". However, since the void layer 14 of the multi-mesh core material 16 used in the present invention is filled with the fluid composition 11, the upper cloth or the lower cloth like a double pile cloth original fabric for making a cut pile cloth. Without making the cloth dense, the double raschel warp knitting machine roughens the lateral vibration spacing X and the ground chain stitch row spacing Y of the insertion yarn 22, and the double pile loom roughens the ground warp density and ground weft density. Then, an opening 18 communicating with the void layer 14 is formed in at least one of the upper cloth 12 as the first mesh and the second cloth 13 as the second mesh.

FIGS. 1, 2 and 3 show a multi-mesh core material 16 knitted by a double Raschel warp knitting machine, and FIG. 4 shows a civil engineering and construction laminate 17 using the multi-mesh core material 16. It is a figure showing a section. The multi-mesh core material 16 shown in FIG. 1 has 3 courses (3 ground stitches)
One insert thread 22 is oscillating (wrapping) for each
In the multi-mesh core material 16 shown in FIG. 2, two insertion yarns 22 are laterally oscillated every eight courses from each chain stitch row to the left and right ground chain stitch rows. When such a multi-mesh core material 16 is knitted by a double Raschel warp knitting machine, one knitted fabric 19a of one of the first mesh 12 and the second mesh 13 is moved to the left and right in the knitting width direction. The two separate connecting members 15a and 15b are used as the two stitches 1 of different knitted fabrics on the other side.
9a and 19b, the connecting members 15a and 15b are connected to the first mesh 12 and the second mesh 13 in the knitting width direction.
It is preferable to incline by 30 to 85 degrees with respect to each other, and by doing so, it becomes difficult for the upper and lower ground chain stitch rows to shift to the left and right, and the gap between the first mesh and the second mesh, that is, the thickness of the void layer. It has a stable structure that is kept constant.

FIG. 5 illustrates a multi-mesh core material 16 woven by a double pile loom, the first mesh 12
The second mesh 13 and the second mesh 13 are the weft yarns 24 that are alternately struck above and below the straight warp yarns 23, respectively.
Is woven so as to pass over it and underneath for the ground weft yarn 24 that dives under the ground warp yarn 23. In the weaving process of the first mesh 12 and the second mesh, a connecting material is formed. 15 passes over the ground weft thread 24a that is under the ground warp thread 23a of the first mesh 12, and the ground warp thread 2 of the second mesh 13
First mesh 1 dive under the ground weft yarn 24b over 3b
2 and the second mesh 13 are connected to each other, and at the connecting points between the first mesh 12 and the second mesh 13, the left and right sides of the connecting material 15 are set to the left and right sides of the ground warp 23 in a pair. Of the ground warp yarn 23 and the ground weft yarn 2 which are sandwiched between the warp yarns 25 of FIG.
The first mesh 12 and the second mesh 13 are sandwiched between the first mesh 12 and the second mesh 13.

When the multi-mesh core material 16 is woven by the double pile loom in such a manner, unlike the case of knitting by the double Raschel warp knitting machine, the ground warp 2
3, the ground weft yarn 24, the warp yarn 25 and the connecting material 15 are 180
Since it is not bent so that the length direction changes more than once, it is possible to use metal filaments that are difficult to bend for them. Especially, since the ground warp 23 and the ground weft 24 can be woven straight, It is possible to use a thick metal wire that is difficult to bend as shown in the figure. On the other hand, the warp yarns 25 and the connecting members 15 that are bent up and down and woven have a thickness of about 1 mm like a binding wire used for binding reinforcing bars.
The following relatively flexible and easily bendable metal wires are used.

In the loom, multiple weaving is possible in which a plurality of woven fabrics are simultaneously woven in a state of being overlapped with each other. This is also possible with a double pile weaving machine. Therefore, the first mesh 12 and the second mesh 12 as shown in FIG. Not only the multi-mesh core material 16 that is doubled with the mesh 13 but also the first mesh 12
It is also possible to obtain a multi-mesh core material in which many meshes such as the third mesh, the fourth mesh, the fifth mesh, ... And the like are further connected to the second mesh 13 with a connecting material.

FIGS. 6 and 7 show a multi-mesh core material 16 formed by using an existing wire mesh constructed by welding a warp bar 26 and a weft bar 27. Two
The wire meshes are arranged parallel to each other and face each other.
The weft lines 27b of the mesh 13 are pin-joined and connected to the connecting member 15, and the first mesh 12 and the second mesh 1
3 and the plurality of connecting members 15 form a parallel lever crank mechanism, and a gap between the first mesh 12 and the second mesh 13 is determined according to an inclination angle θ of the connecting member 15 with respect to the first mesh 12 and the second mesh 13. The thickness D of the layer 14 can be adjusted to be used. Both ends of the connecting member 15 are
Weft bar 27a of mesh 12 and weft bar 2 of second mesh 13
It is a hook 29 that fits into 7b, and its hook tip 28 is directed in a direction N intersecting with the axis M of the connecting material body 15.

When the multi-mesh core material 16 is formed by using the existing wire mesh as described above, the length L of the connecting material 15 is set to the wire mesh (12.1) as shown in the figure.
3) It is shorter than the gap G between the weft lines 27, and the first mesh 1
2 and the second mesh 13 with their meridians 26a and 2
6b facing outward, and those wefts 27a and 27b face inward facing each other, and then overlapped,
The meridian 26a of the mesh 12 and the meridian 2 of the second mesh 13
6b Weft lines 2 of the first mesh 12 sandwiched between 6b and alternately arranged
7a and the weft line 27b of the second mesh 13 on both ends of the hook 2
9. 29 is tapped in and the connecting material 15 is pin-joined. By doing so, it is possible to fold the multi-mesh core material 16 thinner than the total thickness of the thickness of the first mesh 12 and the thickness of the second mesh 13 by the thickness of the weft lines 27, and it is not bulky, and many It becomes easy to stack the multi-mesh core materials 16 and to stack and store them on the bed. At the same time, since the connecting member 15 is also located between the warp lines 26a of the first mesh 12 and the warp lines 26b of the second mesh 13 and does not protrude outward, the connecting member 1 may be transported or otherwise moved in the process of moving the multi-mesh core member 16.
It is possible to avoid the problem that 5 collides with other civil engineering and construction materials and comes off, and it is possible to assemble the multi-mesh core material 16 by a simple operation of tapping the connecting material 15 in this way. And at that time, the first mesh 12
If a large number of meshes, such as the third mesh, the fourth mesh, the fifth mesh, ..., And so on are superposed on the second mesh 13 and the second mesh 13, the double mesh core material 16 shown in FIG. The core material 16 can also be easily obtained.

[0016]

The civil engineering and construction laminate 17 according to the present invention has the first mesh 12 and the second mesh 13 inside the connecting member 15.
Since the multi-mesh core material 16 connected by is embedded and reinforced also in the thickness direction, it is excellent in earthquake resistance.

Since the multi-mesh core material 16 is formed by connecting the first mesh 12 and the second mesh 13 with the connecting material 15, the first mesh 12 and the second mesh 13 at the construction site of the civil engineering and construction laminate 17. It is possible to save the trouble of aligning the intervals between the first mesh 12 and the second mesh 13 by inserting a spacer between them and supporting them with auxiliary muscles.

Since the multi-mesh core material 16 can be made of fiber yarns, it is easy to carry, does not take much time for construction work, is flexible and can be easily constructed on curved surfaces, and is a civil engineering construction laminate facing downwards like a ceiling. No special support frame is required for construction.

In the multi-mesh core material 16 in which the weft muscles 27a of the first mesh 12 and the weft muscles 27b of the second mesh 13 are connected by the connecting material 15 having the hooks 29 that fit into the weft muscles 27, the overlap is made. The hook 29 can be tapped on the weft line 27a of the first mesh 12 and the weft line 27b of the second mesh 13 to easily form the hook 29.

Thus, the weft lines 27a of the first mesh 12
When the weft lines 27b of the second mesh 13 and the second mesh 13 are pin-joined with the connecting material 15, the first mesh 12 and the second mesh 13 are separated depending on the inclination angle θ of the connecting material 15 with respect to the first mesh 12 and the second mesh 13. Thickness D of the void layer 14 between
Since it can be adjusted, it can be applied to various civil engineering and building laminates having different thicknesses.

Then, the first mesh 12 and the second mesh 1
3 to 3rd mesh, 4th mesh, 5th mesh,
Even if the multi-mesh core material 16 with three or more meshes overlapping each other is heavy and difficult to carry, such a multi-mesh core material 16 is 1 mesh 12, 2nd mesh 1
3, 3rd mesh, 4th mesh, 5th mesh, ...
While stacking a large number of meshes, the hooks 29 are tapped on the weft lines 27a and the weft lines 27b of the meshes that are in contact with each other in the vertical direction, and the vertical and horizontal meshes can be connected to each other.

The multi-mesh core material 16 is the first mesh 1
Since the second mesh 13 and the second mesh 13 face each other in parallel at a constant distance D, they can stand on a base such as a base concrete, and the anchor bolt 32 is attached to the connecting member 15.
To attach the multi-mesh core material 16 to the frame 31 and
If concrete (11) is driven into the frame 31, the civil engineering and building laminate 17 such as a cloth foundation or a concrete beam can be formed.

As described above, according to the present invention, the bar arrangement work conventionally performed by binding the main bar and the hoop bar with the binding wire is unnecessary, and the civil engineering and construction laminate 17 can be efficiently installed.

However, the multi-mesh core material 16 is incorporated into the reinforcing bar as a reinforcing material of the reinforced concrete (wooden building laminate 17) when the concrete is driven into the reinforcing bar assembled by binding the main bars and hoop bars with the binding wire. It can also be used in. In particular, for large reinforced concrete structures such as concrete beams and bridge piers, concrete is driven in several times, and there is a qualitative difference in the level of concrete between the concrete that is driven in first and the concrete that is driven in later. When the multi-mesh core material 16 is embedded in the boundary portion between the concrete and the concrete which is driven in several times, the qualitative step of the concrete is reinforced and eliminated by the multi-mesh core material 16 in between, and the reinforced concrete structure is improved in strength. It will be stable. In addition, the multi-mesh core material 16 is applied to the crack occurrence location of the concrete structure where the crack is generated, concrete is placed, and the concrete structure is repaired and reinforced. It can also be used partially.
