Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fabric form for forming a mortar and a concrete layer used for civil engineering work such as formation and protection of a slope such as a river bottom and a bank.

[0002]

2. Description of the Related Art Conventionally, a formwork made of a fabric for forming a mortar and a concrete layer has a structure in which upper and lower two-layer fabrics are stitched at regular intervals so as to secure a columnar cavity having an arbitrary size. The upper and lower layers are sewn or joined using a connecting string.

In recent years, a method of securing a columnar hollow portion by a weaving structure has also been proposed. One of the methods is to arrange a warp of a woven fabric having a double woven structure so as to provide a void in the center of the woven fabric. Open and close the double woven portion of the woven fabric so that only the weft has juxtaposed parts in the center, create a character-shaped part, and connect it continuously to form multiple pillars It is a method of creating a woven formwork having a hollow portion, and still another one is a woven fabric having a two-layer structure in which toji yarn is arranged at an arbitrary interval, in which the toji yarn is bisected and divided into two types. Separately move in the same manner as the ground warp in the two opposite layers, and then separately move in the same way as the ground warp in the opposite layer through the empty weave of any length. Created by repeating
While hollow weaving, a vertical wall part having a continuous approximately rhombus-shaped space made of two kinds of stepped thread that goes back and forth diagonally between the upper and lower layers, and a plurality of columnar cavities formed by the ground structure of the upper and lower layers In this method, a required number of adjacent layers are connected to each other by sewing or the like in accordance with the construction area of a two-layer woven fabric mold having a two-layer structure, thereby forming an integrated woven fabric mold having a predetermined size.

[0004]

By the way, the conventional method of fabricating a fabric form having a plurality of columnar cavities in the longitudinal direction by sewing the upper and lower two-layer fabrics is a method for regularly forming a large surface. Needless to say, the complexity of the sewing operation is of course, and since the cross-sectional shape of each column-shaped cavity of the completed fabric form has a substantially circular shape, after filling with mortar, etc., the shape does not become like connecting cylindrical bodies. However, there was a remarkable problem in terms of contact with the ground and uniformity of strength of the completed concrete layer.

In order to solve the above-mentioned problem, a method has been devised in which the upper and lower two layers of fabric are joined so as to be entangled by using a connecting string. In this method, the cross-sectional shape of each columnar cavity is made substantially rectangular. By this, the surface of the finished mortar and concrete layer was made flat and the thickness was made almost uniform, but the connecting string was uniformly entangled and stopped without drilling holes to induce liquid leakage in the upper and lower two-layer fabrics To do this, extremely complicated work was required, and mass production was difficult and had to be very expensive.

[0006] In a method of forming a large number of character-shaped parts by weaving structure and forming one substantially rectangular column-shaped hollow portion each time one is connected by sewing or the like, the surface of the completed mortar and concrete layer is made flat and the thickness is reduced. Although it is possible to realize substantially uniformity, it is necessary to open the fabrics one by one for each columnar cavity and connect them by sewing or the like, which requires extremely complicated work.

A plurality of pillar-shaped cavities are formed by forming a vertical wall portion having a continuous approximately rhombic space by two types of stepped thread which is skewed between upper and lower surfaces during blank weaving. The method of making a woven form having a part is that the material of the form is a flexible material such as fiber, and the thread is inclined between the upper and lower surfaces. The skew angle of the thread becomes variously varied depending on the size and pressure transmission, and it is very difficult to form a mortar and concrete layer with uniform density and thickness as designed, Before and after filling, there was a drawback that the dimensions of the formwork could not be calculated, and in order to create a formwork of a predetermined size, it was necessary to connect and integrate multiple forms together by sewing etc. was there.

[0008] Therefore, an object of the present invention is to reduce the density of the mortar and the concrete layer by making all the ridge angles in the formwork substantially right angles by the vertical wall portion made of the jiji thread juxtaposed substantially perpendicular to the ground structure. Fabric mortar and concrete with uniform thickness and excellent dimensional stability of the formwork, complete with just the required number of juxtapositions without connecting and integrating the forms according to the size of the construction area An object of the present invention is to provide a molding form at low cost.

[0009]

In order to solve the above-mentioned problems, the invention according to claim 1 is directed to reducing the size of a hole (hereinafter referred to as a hole) which is a column-shaped hollow portion constituting a woven fabric having a perforated weave structure. Toji yarns arranged at arbitrary intervals in the width direction are provided with slack of any length corresponding to the thickness of the mortar and concrete layers, and are formed so as to form a single-layered ear portion at an arbitrary width on both side edges. Cut the woven fabric of the perforated bag weaving structure at an arbitrary length, and create the thread by closing the opening of each hole created by the cutting by sewing or the like. A plurality of vertical walls having a plurality of regular voids, and a plurality of holes having a substantially rectangular cross section formed by upper and lower walls formed by a ground structure having an arbitrary density; Fabric fabrics having a single-layered ear A barrel and concrete molding form.

According to a second aspect of the present invention, there is provided a woven fabric having a perforated weave structure, in which a plurality of toji yarns arranged at arbitrary intervals in the width direction in accordance with the size of the holes are arranged in the same location at an arbitrary width. The mortar and mortar made of woven fabric according to claim 1, which are arranged in rows.

According to a third aspect of the present invention, there is provided a woven fabric having a perforated weaving structure, comprising a plurality of toji yarns arranged at arbitrary intervals in the width direction according to the size of the holes, and upper and lower wall portions having an arbitrary length. After moving in the same manner as the upper or lower ground warp of the tubing to be formed, the vertical wall portion is provided with any necessary slack, and then the same as the lower or upper ground warp on the opposite side of the woven cloth. By alternately repeating the movement with the length, the toji yarn is moved in the same way as each ground warp yarn, the regular rectangular multiple spaces of the vertical wall generated while moving, The mortar made of textile and the concrete molding form according to claim 1 or 2, wherein a plurality of holes are connected at arbitrary positions in the longitudinal direction.

Further, according to the present invention, a plurality of rows of toji yarns, which constitute a woven fabric having a perforated weave structure, are arranged at arbitrary intervals in the width direction and at the same location and within an arbitrary width in accordance with the size of the holes. After the bisected and separated two types of toji yarns are moved in the same manner as the ground warp yarns on the upper surface and the lower surface opposite to the lower surface of the woven fabric forming the upper and lower wall portions at an arbitrary length, the vertical wall portion is required. The sagittal thread moves in the same way as the ground warp yarn by alternately repeating the movement of an arbitrary length in the same way as the lower surface and upper surface warp yarn of the opposite side of the woven cloth, respectively, provided slack of arbitrary length. While avoiding uneven distribution in the ground texture on one side, the regular rectangular multiple spaces of the vertical wall portion generated while the toji yarn moves like each ground warp,

By closing the opening surface H by sewing or fusing, a mortar made of textile and a concrete molding form having a predetermined size can be obtained.

[0015] The ear 5 composed of one layer is usually formed by simultaneously weaving by making a binding bag weaving structure with an arbitrary width on both side edges when fabricating a fabric having a porous bag weaving structure. If the purpose is achieved, it is possible to form the two-layer fabric by any other method such as sewing or fusing the same upper and lower side edges with an arbitrary width to form a single-layered ear portion 5, In order to prevent leakage of mortar, etc., the warp density at an arbitrary position around the one-piece ear portion 5 is made denser than that of the ground structure other than that position.

The mortar or the like is pumped in the direction of F from a pumping port provided at an arbitrary position of an arbitrary hole I, and the respective holes I are connected by a regular substantially rectangular space D of a vertical wall portion E. Therefore, the mortar and the like that have been pumped are filled in each hole I while being dispersed in the direction of F ′. Therefore, in the fabric mortar and concrete molding form according to the present invention, a small number of Is provided, all spaces in the mold can be filled with mortar or the like.

In the case of (III), the point at which the toji thread 13 has moved by several wefts in addition to the toji thread 12 is moved in the same manner as the toji thread 12 by the length B 'in (III). In the case (II), the substantially rectangular regular space D of the vertical wall portion E in the case (II) has a plurality of holes I arbitrarily. Are connected linearly at the position (3), and in (III), the lengths B and B 'are connected in a shape other than a straight line such as a zigzag pattern in which the lengths B and B' appear at will.

In FIG. 4 (II), the size of the regular thread space 14 and the regular thread space 15 of the vertical wall portion E in FIG. As described above, the upper surface ground structure 3 and the lower surface ground structure 4 are provided so as to prevent the remnant yarn from being unevenly distributed in the ground structure on one side by the movement of the stepping back while providing the slack of the length ensuring the height C.
The warp thread 14 is, for example, the jiji thread 14 is the warp thread 8,

As shown in the figure, the suction-prevention sheets 19 are juxtaposed in such a manner that the suction-prevention sheets 19 are not exposed at all by the one layer of the ears 5 which are alternately overlapped.

In this case, it is described that the one-piece ears 5 alternately overlap with the upper and lower surfaces of the adjacent side as shown in the figure. However, if it is possible to prevent the suction prevention sheet 19 from being exposed, for example, It is possible to use any other method such as connecting the ears 5 composed of one layer adjacent to each other and bent in the direction of the upper wall of the form using a connector.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Examples of the present invention will be described below with reference to a mortar made of fabric and a concrete molding form using a high-strength nylon yarn for the ground structure and a high-strength polyester yarn for the jiji yarn.

The upper and lower surface textures are woven with a density of warp nylon filament 840D / 2 × 22 filaments / inch and a weft nylon filament 1260D / 1 × 24 filaments / inch, having independent ears on the upper and lower surfaces of both side edges. Width
A plain thread of 2005 mm was used. Toji yarn was made of polyester 1500D / 2 at the same location at an interval of $ 55 mm from the ear. Five toji yarns 14 and four toji yarn 15 in FIG. 3 ground warp yarns between each yarn
Every other thread is placed within a width of $ 20 mm by threading one by one, and the pallet thread 14 moves in the same manner as the warp thread 8 of the top surface texture 3 over a length of $ 50 mm, and then has a length of $ 80 mm. , And then alternately repeat the same movement as the warp 9 of the lower surface texture 4 over a length of ≒ 50 mm, and the resilient thread 15 is the same as the resilient warp always opposite to the resilient thread 14. By alternately repeating the length movement, a 織物 80 mm high woven fabric with a width of ≒ 2005 mm having independent ears on each of the upper and lower surfaces on both sides is ≒ 55 mm.
26 vertical wall portions E having a width of ≒ 20 mm regularly having a substantially rectangular space D having a size of ≒ 50 mm × ≒ 80 mm;
The substantially rectangular opening surface H has 25 holes I of ≒ 55 mm × ≒ 80 mm, and all the holes I are linearly connected by the substantially rectangular regular space D of the vertical wall portion E. We made a woven fabric with a perforated bag weave.

The woven fabric of the perforated bag weave structure thus produced is cut into five pieces each having a length of ｍ5 m, and the cut side edges of the both side edges of the woven fabric are overlapped with each other on the same side edge side to obtain 840 D / By suturing with a width of 30 mm from the side edge by six straight stitches using 1 × 3 nylon sewing thread, one-layered ears 5 are formed on both side edges of the fabric, and all the opening surfaces H are formed. To close both cut edges using the same sewing thread 100 mm inside from the end,
By suturing with three straight stitches and leaving the upper and lower edges of the formwork so as to leave a margin of $ 80mm, a mortar made of woven fabric and concrete molding with a width of $ 2.0m and a length of $ 5.0m can be obtained. Five completed.

The above five woven mortar and concrete molding forms are prevented from being sucked out of the construction slope so that the ears 5 made of one layer are alternately overlapped with the upper and lower sides of the adjacent side as shown in FIG. After placing them side by side on the sheet 19 and driving in the pile at an interval of $ 1 m close to the upper and lower edges of the formwork, a wooden patch of the same width as the margin is pressed against the upper and lower edges of the formwork, and the thickness is 200 mm. After the steel anchor pin is driven to penetrate the backing material and the margin at an interval of, and the driving pile and the anchor pin adjacent to the driving pile are connected and fixed by bolts, cement is 600 kg / m ³ , and water is 360 kg. / M ³ , fine aggregate is $ 1,200 kg / m ³
Make a mortar of each, and from two places, near the center of the length of one hole near the center and near the upper edge of each woven mortar and concrete molding form, through a sharp tip through the upper wall When the height of the formwork is reduced to ≒ 80 mm in all parts, the pumping is stopped, and after pulling out the pumping pipe, correcting the structure of the ground structure at the insertion point is performed. Finished work.

[0030]

In the mortar and concrete molding form of the present invention, all spaces filled with mortar and the like have a substantially rectangular cross-sectional shape, and the vertical wall portions are juxtaposed substantially perpendicular to the ground structure. Since all the ridge angles inside the form are almost right angles because of the resilient thread, the influence of the magnitude and direction of the mortar and other pumping pressure despite the fact that the material of the form is extremely flexible fiber This makes it possible to calculate the dimensions very accurately with little influence on the ground, and to exert the maximum drag against the ground distortion after the laying caused by a large pumping pressure or an earthquake.

The formwork constructed in this way has good dimensional stability, while having excellent flexibility, which enables laying sufficiently conforming to the unevenness of the laying surface. The mortar and concrete molding formwork can be carried to the formwork laying site in an unfinished state, and processing can be added at the laying site to complete the formwork. It can be reflected on the mold.

Further, a large internal space having a substantially rectangular cross-sectional shape composed of only the thread which is juxtaposed substantially perpendicularly to the upper foundation structure and the ground structure of the mortar made of fabric and the concrete molding form of the present invention is a mortar or the like. This makes it possible to greatly expand the range of choice of fillers, and to make the packing density of mortar or the like extremely uniform.

The mortar and concrete molding form of the present invention can be completed only by joining the upper and lower cut edges of a woven fabric having a porous bag weave structure having an arbitrary area. Compared with the formwork, it is possible to make it extremely inexpensively and easily.

Further, the structure in which the thread is juxtaposed substantially perpendicularly to the ground structure hardly limits the height and can secure a stable height. It is possible to sufficiently meet the requirements for the height, and it is possible to always secure a stable flat state height for any requirement for the height.

Further, the ear portions each having an arbitrary width formed on both side edges alternately overlap with the upper and lower surfaces of the adjacent side portions, so that the formwork is prevented from being sucked out by merely juxtaposing the frames without connecting them together. Since the exposure of the sheet can be easily prevented, the processing cost and the transportation cost can be significantly reduced.
