Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the creation of a concrete structure with excellent shear strength, and the present invention relates to the creation of a concrete structure with an excellent shear strength, and a concrete structure in which the shear strength is effectively improved with a relatively small amount of steel material, in a relatively simple and low-floor construction. The present invention is designed to facilitate the use and construction of three-dimensional structures.

Concrete members and other concrete structures using hydraulic substances such as cement, gypsum, or calcium silicates, or fluid mixed substances such as resin mortar or resin concrete have been used in various ways for a long time. Its properties such as excellent compressive strength and durability make it suitable for permanent structures, etc., and since it can be obtained in a relatively low floor space, it is widely used as an indispensable material for various types of construction, civil engineering, etc.

It is also common to use reinforcing bars for the purpose of improving the strength of such concrete members, and it is possible to obtain a considerable increase in strength, but the strength improved by such reinforcing bars is mainly due to tensile strength. There is almost no means to improve the shear strength to an appropriate degree.

However, it is clear that the destructive force that specifically acts on this type of concrete member is a combination of not only compressive force and tensile force but also shear force, no matter what form it takes. The main cause of failure in such concrete members is often due to insufficient shearing strength, and even in the specific design and manufacturing process, sufficient thickness is required for the member to ensure such shearing strength. Therefore, the concrete structure has to be quite thick.
It is well known that it inevitably requires a lot of materials and costs, and is also heavy, requiring heavy muscular work and electrical equipment work for cargo handling and handling.

Of course, steel is a material that is excellent in terms of compressive strength, tensile strength, and shear strength as described above, but this steel material is obtained as a result of metallurgical refining work at high temperatures and over a long period of time. Moreover, it requires more intensive rolling, welding, and other processing to obtain the concrete parts, so it has to be considerably more expensive than concrete parts. has the fatal defect of being easily corroded, which limits its use, and requires a certain amount of anti-corrosion coating, making it even more expensive.

In addition, to form a specific structure, further bending processing,
A cutting process such as torch cutting, a welding process, or a joint process using a coupling material and a large number of bolts and nuts are required, and all of these processes are complicated.

The present invention was created through repeated research and speculation in view of the above-mentioned circumstances.

That is, the reinforcing connecting material used in the present invention uses a material 1 as shown in FIG. They are formed by connecting them so that they fit together.

The material 1 of the lid is a spiral wire rod, and its structure has an axial pitch P corresponding to approximately twice the width W in the connection direction.
In some cases, this material may be appropriately compressed, i.e., the button shown in the figure may be made with sufficient bulk to provide appropriate shear strength as described above. As shown in Figure 1, the spiral is formed with a perfect circular cross section, but depending on the case, it may be formed into an oval or elliptical shape, and furthermore, the wire may only have a circular cross section. square, polygonal, rectangular (strip)
Alternatively, a cross-sectional structure similar to that of a deformed steel bar with a reduced cross-section may be adopted.

Further, in the following illustrations and embodiments, a single wire is used as the material 1, but in some cases, a wire made of a plurality of twisted metal wires may be used.

In order to form such a stranded wire, a suitable length of fibrous material such as metal fiber material or glass fiber is interposed between two or more wire rods, as shown in Fig. 1D. It is clear that the coupling with the injected crosstalk can be improved by making it a solid.

However, in any of these cases, the spiral structure itself is used to connect the materials in a playful manner, and the assembly method is to fix one material and attach the other material to it. While rotating according to the spiral pitch, push along the axial direction of one of the materials and introduce them together, or introduce the materials on both sides in the middle, taking a space smaller than the width of the materials to be brought together and moving the material axis in the same manner as above. In either case, they are properly linked by rotating while pushing in the direction.

Of course, it is also possible to rotate both materials while pushing them in their respective axial directions. Therefore, the reinforcing connecting member shown in FIG. 2 formed in this way is one in which the materials are connected to each other. Even if there is, each material is substantially in a free state and freely bends in the connecting direction, and the width can be appropriately shortened by forming an aggregated state of each material.

These facts indicate that the reinforcing link material of the present invention has excellent characteristics in terms of cargo handling and construction. This shows that the connecting material 2 can be removed, and it also means that it can be set by freely adapting to the shape of the member to be used, the curvature, and unevenness of the construction surface. This means that it is possible to form an extremely compact packing form, and also to be able to arbitrarily form precise material arrangements in certain parts during construction.

A side view of the reinforcing connecting member according to the present invention in the 45° direction indicated by the arrow ■ in FIG. 2 is shown in FIG.
Noticeable peaks 11. Tanibe 12
is formed continuously, and this relationship is similar to that shown in Fig. 2 when viewed from the direction of arrow A portion 12 is formed on the back side of the reinforcing member 2, which is opposite to that shown in FIG.

It is extremely significant that the peaks 11 and valleys 12 are disposed opposite each other on the front and back sides in an intersecting relationship in the inclination direction. Regardless of the structure shown in the side views shown, since the material 1 used is a spiral material curved with a certain inclination as described above, it is possible that the materials are interconnected. For the reinforcing link material thus formed, the special relationships shown in FIGS. 3 and 4 described above are clearly obtained, and the peaks 11. As will be described later, the valley portion 12 effectively functions as a fitting portion or a receiving portion when used.

Copper wire is generally used as material 1, but in some cases synthetic resin material can be used, and even in the case of parent metal materials, plating, chemical treatment, or resin coating may be applied for corrosion prevention purposes. It is preferable to use a material such as stainless steel, and of course, stainless steel or the like may be used.

Since each of the materials 1 of the above-mentioned reinforcing connecting material 2 has a three-dimensional spiral structure, it is clear that the reinforcing bars 2 can be used by appropriately incorporating reinforcing bars into its structure. , this state is shown in FIG.

That is, it is clear that the reinforcing bars 3 can be inserted and arranged in the spiral, and furthermore, the reinforcing bars 3 can be inserted into the spiral, and the third inclined bars 4°4 can be placed on the front side and the back side of the reinforcing connecting member 20, respectively. , 4. Arc-shaped valley 1 as shown in Fig. 4
By arranging the reinforcing bars as shown in FIG. 2, it is possible to obtain a crossed inclined reinforcement structure.

Of course, there is enough space in the width direction to insert the reinforcing bars 3, and in any case, the reinforcing bars can be attached very freely.

However, it goes without saying that the reinforcing bars arranged in this manner can freely obtain the required tensile strength in the concrete member that is the object of the present invention.

Furthermore, the above-mentioned reinforcing bars can also be used as ones connected to the reinforcing connecting member 2 itself. For example, the connecting parts 5 of the materials 1, which are spiral wires, are loosely connected and the connecting parts 5 are connected to each other. If reinforcing bars are inserted to form the reinforcing bars 2, it is possible to use the linking portions to form the reinforcing bars, and to prevent the reinforcing bars from being pulled out, the ends of the reinforcing bars 6 can be It may be bent and connected to the reinforcing connecting member 2.

The reinforcing link material 2 as described above can be used by polymerizing as appropriate, and the polymerization state includes a case where the materials 1 of each reinforcing link 2 to be polymerized are polymerized in the same direction,
There are cases where the materials are polymerized with their directions crossing each other, but in the former case, the material according to the present invention is the third method described above.
, 4, the mountain portion 11 is formed as shown in FIGS. 3 and 4, although it is inclined in the direction shown in FIG. 2. Reinforcement connecting material 2 composited by setting valleys 12 so as to overlap each other
It is easy to understand that the thickness of the structure can be reduced by at least 50%, and by assembling the structure in such a manner that the peaks and valleys engage with each other, multiple reinforcements can be achieved. It can be seen that the connecting members 2.2 can achieve the various strength relationships effectively combined with concrete, especially without welding or other forms of modification.

Furthermore, the state in which the material 1 is polymerized with the spiral axes perpendicular to each other is as shown in FIG. The ridges 11 are fitted into the respective ridges 12 in a symmetrical relationship (in Fig. 2, the arrow ■ direction and the arrow ■ direction are perpendicular to each other, but in this way, the axial direction of the material 1 is In the case where the reinforcing materials 2, 2 are polymerized in the following manner, the direction of the arrow ■ and the direction of the arrow ■ in FIG. It is obvious that the direction is parallel to the direction of the arrow {circle around (2)} in the other reinforcing material due to the cross-polymerization of the other reinforcing material 2 as described above. )
It is clear that both reinforcing links 2.2 can be superimposed in areas of approximately the same thickness (only the thickness increases by the cross-section of the material).

Of course, for such a superposition state in which the materials 1 intersect, an effective union relationship between the two reinforcing connecting members 2, 2 can be obtained, which is more than in the case of the above-mentioned superposition in the parallel state of the materials 1, and welding As mentioned above, the engagement relationship can be formed without any other processing, but it is more preferable that the reinforcing linking material 2 is flexible in the width direction as described above by polymerizing the materials 1 in an intersecting relationship. The flexibility and shrinkability of the reinforcing connecting members 2, 2, which were in a free-flowing relationship that could be fully collapsed in It is to become a connecting material.

Even if it is in a re-spiral shape, each material 1, which clearly has a certain degree of rigidity, is assembled in an intersecting relationship, so that the flexibility in the width direction that each reinforcing connecting member had is lost. can be.

In addition, by overlapping the connected spiral materials 1 as described above, the fitting and polymerizing relationship can be properly maintained, and a simple and appropriate polymerization state can be achieved, just as in the case of attaching to a Velcro tape. Even though it is formed, by fixing it as a rigid body, the fitting relationship becomes stable and an effective bonding relationship is achieved.

However, since it is not specially welded or bound, such bonding and polymerization state can be released as appropriate, and the polymerization state and relative position can be changed, just as in the case of Velcro tape described above. In any case, it should be fully understood that these characteristics are excellent for use at construction sites, etc.

A special example of such cross-polymerization of the materials 1 is shown separately in FIG.

That is, in the case of this FIG. 7, the material group 1a whose spiral axis is positioned along the vertical direction in this figure is constructed in exactly the same way as that shown in FIG. It incorporates a group of materials 1b in which the spiral axis is positioned along the horizontal direction in the drawing, and this material 1b
When assembling the group, the reinforcing connecting member 2 made of the material 1a group is made of a material.

By advancing the material 1b while turning it in the axial direction according to its spiral configuration, accurate incorporation can be achieved based on the relationship between the pitch P and the width W as described above. Can be linked.

The planar structural relationship and lateral structural relationship of the object shown in Fig. 7 are slightly different from those shown in Fig. 6 described above, and in the case of Fig. 7, each material once assembled is Although it is generally not possible to separate the reinforcing materials consisting of group 1a or group 1b as shown in FIG. 6 and described above,
Since the material groups 1a and 1b are precisely combined, the steel material becomes a three-dimensional steel material and each material is rationally connected to exhibit appropriate shear resistance.

However, in general, configuring the structure as shown in Fig. 7 requires a certain number of man-hours and is costly, and even if it is configured as shown in Fig. 6, it is difficult to achieve a shear strength that does not have much significant difference. 6 is sufficient except in special cases.

It is clear from the state of each figure B that sufficient gaps are left in the vertical and horizontal directions for inserting the auxiliary reinforcement in both cases of the above-mentioned buttons shown in Figs. 6 and 7. , and also has a similar insertion gap in the oblique direction.

Therefore, the products shown in Figs. 6 and 7, in which reinforcing bars 3 and 4 are appropriately incorporated in the same manner as in the case shown in Fig. 5, and the reinforcing connecting material 2 is polymerized as described above, have better quality. It is clear what will be shown.

The above description relates to each material and the reinforcing connecting material alone, but the reinforcing connecting material of the present invention as described above can be used by freely connecting in three-dimensional directions such as the Z axis, the Y axis, and the Z axis. can.

This relationship can be fully understood from either the relationship shown in FIG. 5 regarding insertion and assembly of reinforcing bars, or the relationship shown in FIGS. 6 and 7 regarding overlapping use.

In other words, when the reinforcing linking material 2 as described above is intended for linking in three-dimensional directions, it forms a limited polymerized state in only a portion of the reinforcing linking material 2, for example, A in FIG. Or the range corresponding to at least one material 1 at the left end or right end of another similar reinforcing link material with respect to the right end or left end of the reinforcing link material stretched in the state shown in C. It is clear that reliable connection in the width direction can be obtained by overlapping as shown in Fig. 7 and inserting longitudinal reinforcing bars 3 at this overlapping portion.

Similarly, the lower end or upper end of another reinforcing link material is partially overlapped with the upper end or lower end in FIG. Can be connected.

If it is troublesome to insert reinforcing bars 3, by forming an overlapping relationship as shown in Figs. It is also possible to obtain a connection that can effectively transmit tensile force and the like, and in any case, such a connection operation is extremely simple on site.

A connection that is technically more advantageous than the above connection is shown in FIG.

That is, since the reinforcing linking material 2 according to the present invention is able to bend freely for each material 1 as described above, the second reinforcing linking material 2a is placed in the middle of the first reinforcing linking material 2a, which is positioned horizontally in the drawing. One end side 2b' of the reinforcing connecting material 2b is overlapped by the method described above, and the second reinforcing connecting material 2b is bent in the middle to form the other end side 2tj at a right angle or any other arbitrary angle.
It is also obvious that the third reinforcing linking material 2C can be appropriately superposed on the other end of the second reinforcing linking material 2b drawn out in this way.

Of course, if it is necessary to ensure that each reinforcing connecting member assembled in such a connection structure does not come loose even when subjected to tensile force or other forces, it is necessary to install vertical rods or horizontal rods at each overlapping position as appropriate. The reinforcing bars 3 are inserted in the same manner as in the case of assembling the reinforcing bars shown in FIG. 5, and concrete is poured between them to fully integrate them.

In addition to the above-mentioned connections in the vertical and horizontal directions, connections at angles as shown in Fig. 8 can be made at any position, and without the need for welding or tying. It is clear that the present invention, which can be formed freely, has great advantages both on-site and industrially.

As a result, reinforcing connecting materials can be freely used in accordance with each construction purpose and structure, and preferable use for three-dimensional space can always be made easily and appropriately.

As mentioned above, a major feature is that even when two reinforcing connecting materials are polymerized, their thickness does not increase at all.As already explained, the material according to the present invention has sufficient shear strength In general, the thickness of concrete structures can be significantly reduced due to the fact that it adds to the wall thickness, and interior materials ( Although it would be against the characteristics of the reinforcing connecting material (as described above) to double its thickness through polymerization and connection, the reinforcement of the present invention can hardly increase its thickness even through polymerization. Connecting members can maximize the advantages of the concrete structure of the invention.

Some examples of concrete structures according to the invention are shown in FIG.

That is, A for this figure 9. Both B and C show the case of a flat concrete structure, but as mentioned above, the structure according to the present invention can be used in a three-dimensional structure without the need for special joint members. This is obvious from the relationship shown in Fig. 8, and the tube body 20 or the ■-shaped beam 21° having a three-dimensional cross-sectional structure as shown in Fig. 9, E, or the internal cavity as shown in Fig. It can be freely used as a member 22 incorporating various materials 19 for heat insulation and soundproof purposes.

Further, as a concrete structure having a three-dimensional structure according to the present invention, it is possible to appropriately obtain a polygonal pile body 23 or a tube body 24 as shown in G and H in FIG. However, products with excellent strength cannot be obtained unless centrifugal force molding is used.

If this centrifugal force forming is used, the cross section of the product will inevitably have a circular cross section, but according to the present invention, the strength of the polygonal cross section as shown in FIG. A concrete structure with excellent properties can be appropriately manufactured.

In any case, it is sufficient to pour concrete or mortar 8 with reinforcing bars 3 and 4 appropriately arranged on the reinforcing connecting member 2 as described above, and the poured concrete or mortar is It is clear that the reinforcing link material 2 having the three-dimensional structure described above can be appropriately entered and integrally bonded thereto.

As the reinforcing connecting material 2, the diameter of the material 1 can be arbitrarily selected, and for example, wire rods ranging from about 0.2 to 0.3 rrvn can be used, but if the diameter of this wire rod is 0. The present inventor et al. Adopting the depressurization or injection method under normal pressure proposed for the bag, or injection molding with coarse aggregate packed in the spiral of each material in advance as shown in Figure 2 and Figures 5 to 7. You can choose any method such as

For the reinforcing bars 3 and 4 mentioned above, mix concrete or a hydraulic material such as mortar with increased tension as necessary, and after hardening, release the tensile force and apply tensile force to the concrete. be able to.

That is, by arranging deformed PS steel wires or the like as the reinforcing bars 3 and 4 inside the spiral material 1, cracks due to misalignment between the concrete and the reinforcing bars can be prevented, and a large adhesion force can be expected.

Moreover, the distortion of the concrete inside each spiral material 1 in the direction perpendicular to the axial compressive force is restrained by the spiral structure, resulting in an excessively large proof strength.

FIG. 10 shows a unique embodiment of the present invention in which a wall surface, etc. is constructed using a molded body such as a tile, in which a dovetail-like fitting groove 9 is formed on the back surface. A reinforcing connecting material 2 in which two or more materials 1 as described above are connected to a molded body 10 such as a tile is used, and the material 1 (in some cases The intermediate material 1 is employed, and the remaining materials 1 on both sides are bent and folded to form an overlapping state so that a similar relationship can be achieved) are fitted along the length direction of the fitting groove 9.

In other words, since the material 1 has a spiral structure, it has a certain degree of deformability in the radial direction, and can be easily press-fitted by positioning it along the entrance of the fitting groove 9. However, it is also possible to position the end of the material 1 toward the end of the fitting groove 9 and then slide it in the axial direction of the material 1.

Since the reinforcing linking material 2 fitted as described above forms a state in which the portion corresponding to at least one material 1 protrudes from the back surface of the molded object 10, the back surface of the molded object is If the reinforcing connecting member 2 is further properly attached to the protruding portion, a three-dimensional anchor structure can be formed on the back of a flat tile-like molded body, and such an anchor structure can be used. If so, it is clear that effective and stable construction of tiles, etc. can be achieved.

It is well known that a professional tile craftsman is generally required to install the molded body 10, such as a lid tile, on a wall surface using mortar or the like. The reason for the difficult construction required is that it is difficult to attach and fix tiles, etc., which have considerable weight and are essentially flat, to the wall surface, but the reinforcement according to the present invention as described above If the connecting member 2 is used, it is possible to create an extremely effective anchor structure that greatly protrudes from the back side, and it can be constructed easily.

In addition, as described above, at least one portion corresponding to the material 1 is largely protruded from the back surface of the molded body 10.
However, sufficiently stable construction can be achieved, and attachment to the foundation member 15 etc. can be carried out by any method.

In any of the cases shown in Figures 9 and 10 above, the poured concrete and the three-dimensional reinforcing connecting members intersect with each other and are integrally formed, resulting in the formation of concrete. The excellent compressive strength it has and the reinforcing action of the reinforcing link material are accurately integrated three-dimensionally, and of course the bond between them is also strong, and all of the compressive, shear and tensile strengths are improved. Effectively improved concrete structures can be obtained, with the result that even fairly thin layers of concrete can have strength and durability that are fully comparable to those of full-length concrete.

For example, in the case of conventional steel frames and reinforced concrete beams, it is important to carefully assemble a large number of auxiliary reinforcements called stirrups after installing the main steel reinforcement or reinforcing bars, and to tie them together with wire or weld them. It is generally known that the number of man-hours required by the method is extremely high, and the bond between the reinforcing bars and the concrete cannot be properly obtained, so that the strength cannot necessarily be effectively obtained. As a result, it is possible to solve these problems all at once, and it is possible to assemble within a short time, and as mentioned above, it is possible to obtain appropriate strength even with a relatively thin concrete structure. The construction can be extremely advantageous in terms of quality of materials, man-hours, and other aspects.

A specific manufacturing example of the product according to the present invention will be described below.

Manufacturing Example 1 To obtain a strip-shaped concrete structure with a cross section of 2.5 x 10 crrL, three reinforcing bars with a diameter of 6 m were arranged along the length inside the concrete structure according to the conventional method. A reinforcing connecting member 2 of a three-dimensional structure as shown in Fig. 2 is obtained by connecting two of the above-mentioned reinforcing bars and 15 spiral materials formed using 1 ml iron wire with a diameter of 2 cm and a pitch of 4 cTL. A product according to the present invention in which a steel material was disposed inside the product (the amount of steel used in the product according to the present invention was reduced by 24.7%) was manufactured.

The mortar used in these productions had a cement to sand ratio of 1=1 and a water-cement ratio of 0.35, which was prepared by mixing 1% of the amount of cement with a dispersant.

The shear strength of the resulting concrete structure was measured 7 days after demolding.

That is, the above-mentioned strip-shaped concrete structure 15CIr
Place it on the lower support points spaced apart by L, and place the upper pressure points at a position 5cIrL inward from one of the support points and at a distance of 10CrIL beyond the one lower support point. (The distance between the two upper pressurizing points is the same as the distance between the lower supporting points, 15 cm).The test result was 52.8 K? using a known shear strength testing device. /cyit, whereas the one according to the present invention is 74.2 to 9/-,
It was confirmed that the shear strength of the present invention was significantly increased.

Manufacturing Example 2 The reinforcing bars have the same cross-sectional dimensions as those in Manufacturing Example 1 and have a diameter of 2.9 rran (3 wires for the conventional method and 2 wires for the present invention, which is the same as Manufacturing Example 1). The amount of steel used is 3.7% according to the present invention.
Each product was manufactured using the same conditions and materials as Manufacturing Example 1, except that the piano steel wire was manufactured by applying a prestress of 2 to 9.

The shear strength of these products was tested and measured in the same manner as in Production Example 1, and the results showed that the products obtained by the conventional method were 59.
．． 8 K9/cit, whereas that using interlocking reinforcement 2 as described in accordance with the present invention was 80.3 K9/cit.
．． It was found that the shear strength could be sufficiently improved in the same manner as in Production Example 1.

Production Example 3 The same cross-sectional dimensions as in Production Example 1, the same reinforcing bars and the same interconnecting reinforcement material 2 were used, and the fluid kneaded product had a particle size of 0,
The compressive strength of the product filled and molded using a resin mortar containing 3 parts by weight of dry sand with a coarse grain ratio of 1 to 0.6 mrn and 1.2 is around 1100 and 9A□. In such a structure, the shear strength of the structure using the reinforcing connecting material of the present invention as described above (two reinforcing bars) was 411 to 9/crIt, whereas that of the structure using the conventional method that does not use this. The shear strength of (3 reinforcing bars) is 29
It was 5 to 9/CrjL.

According to the present invention as explained above, the shear strength applied to this type of concrete structure can be appropriately improved in general by the reinforcing connecting members connected in a network,
Moreover, the necessary materials are relatively easy to obtain and can be obtained at a low location, and their use in concrete structures is also easy and appropriate, and they can be freely employed in three-dimensional structures, thereby improving the performance of this type of concrete structure. It can be said that this invention has a great industrial effect, since it can be used to a great extent and be used advantageously with a relatively small amount of steel material.
