Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing a main part of two members to be connected. The following description is made by taking concrete as an example of the material of the member. The connecting member of the present invention is used for connecting two members as shown in FIG. 1, for example. These members A and B are each made of a concrete block, and their joint surfaces 1 and 2 are previously provided with dovetail-shaped recesses 1a and 2 respectively.
a. The recess may be rectangular, and 1a and 2a may be of different shapes including the dovetail recess.

FIG. 2 is a sectional view showing an example of a connecting member used to connect the two members A and B. The connecting member 10 has a closed portion J formed separately from a bag 10a made of a flexible material and a partitioning material 10b made of a flexible material or a non-flexible material. The partition member 10b is provided in the vicinity of the constricted portion 13, that is, near the boundary between the joining surfaces 1 and 2, and the bag body 10a and the partition member 10b are bonded with an adhesive, a bolt, a nail, or the like. The connecting member 10 is a tubular bag that is long in a direction perpendicular to the paper surface, and has a hollow convex shape in which a base 11 and a protruding portion 12 are connected by a constricted portion 13. The base 11 has a substantially circular cross section so as to match the shape of the concave portion of the member, and is connected to a protruding portion 12 having a protruding shape via a constricted portion 13. In principle, the base 11 corresponds to the shape of the recess, but any shape may be used since the filler is contained therein. The protrusion 12 may have any shape as long as it can be easily fitted into the recess of the member. The shape of the constricted portion 13 may be any of a curved line, a broken line, and a straight line. Moreover, you may use the partition material 10b which has the collar 10c as needed. This prevents the base from jumping out to the protruding portion side by the pressure when the hollow portion 14 of the base 11 is filled with the filler. The connecting member may have the shape shown in FIG. 2, and the base, the connecting portion, and the protruding portion may be integrally formed of the same material.

The material of the connecting body bag 10a and the partitioning material 10b may be any material as long as it has strength in addition to flexibility. For example, rubber is typical, but other materials such as resin, ceramics, glass, Examples thereof include those woven with inorganic or organic fibers such as carbon and aramid, and nonwoven fabrics. When the material is rubber, resin, aluminum, or the like, the elongated shape having the base and the protruding portion can be easily formed by extrusion molding. Further, it can be easily manufactured by deforming a ready-made plate made of rubber, resin, aluminum, iron, non-ferrous metal or the like with a mold. Further, the woven or non-woven fabric such as carbon fiber and aramid fiber may be molded before or after the use of a mold, solidified with a resin, or molded by heat. As the other non-flexible material of the partition member 10b, in addition to iron and non-ferrous metals, the above-mentioned materials having rigidity are preferable.

FIG. 3 is a sectional view showing a state in which two members A and B are in contact with each other, and FIG. 4 is a sectional view showing a state in which both members A and B are connected.

First, as shown in FIG. 3, the connecting member 10 is attached to the member B. That is, the base 1 of the connecting member 10
1 is fitted into the recess 2a of the member B while crushing. At this time, the constricted portion 13 of the connecting member 10 and the partition member 10b are
However, if there is no problem in contact and subsequent filling of the members A and B, they may be out or over. After attaching the connecting member 10 to the member B in this way, as shown in FIG.
Abut. At this time, when the members A and B are lightweight, the members A and B are temporarily fixed so as not to be peeled off by the filling pressure. Further explaining the state of installation of the partition material,
The base member 11 is inserted while being crushed at the recess opening 17b of the recess of the member B, and the partition member 10b is fitted into the recess opening 17b. If there is a gap between the partition member 10b and the recess opening 17b, the gap may be left as it is, but if there is a bearing, the auxiliary plate may be packed. In addition, even when the collar 10c is provided, the collar may be crushed or inserted obliquely.

The method of filling the filler is such that before the two members A and B come into contact, the base 11 is filled with the filler through the filling port 15b, and then the filler C is injected through the filling port 15b. There are cases. In each case, as shown in FIG.
The hollow portion 14 of the connecting member 10 is filled with the filler c,
Is pressed against and inscribed in the recess 2a of the member B. At this time, the air in the hollow 14 of the recess is discharged from the exhaust port 16b.

Next, when the filler C is injected from the filling port 15a of the member A, the protruding portion 12 is inscribed in the recess 1a of the member A similarly to the above-mentioned member B, and the air in the hollow 14 is provided at an appropriate interval. It is discharged from the exhaust port 16a. The filling of the filler of the member A is performed in accordance with the degree of curing of the filler of the member B, but depending on the material of the filler or the shape of the recess 2a, it may be performed in a non-cured state or a semi-cured state. In addition,
If the air filling the recesses 1a, 2a of the members A, B is discharged from the gap between the joint surfaces 1, 2 or the end of the connecting member, the exhaust ports 16a, 16b can be omitted. As the filler C, mortar, resin, rubber, or the like, if necessary, the above-mentioned organic,
A curable material mixed with inorganic fibers is preferred, but a liquid such as water or oil, or air may be used depending on the purpose of use of the members A and B.

As described above, the joint surfaces 1 and 2 of the members A and B, that is, the joints, are constantly subjected to stress in the horizontal, vertical and oblique directions, and are constantly subjected to repeated stress. When it is important, a connecting material that can cope with this is necessary. The present invention is an invention for solving this problem. That is, various partitioning materials and bags suitable for the purpose of the members A and B can be appropriately selected, which is economical and rational. A material corresponding to the partition member receiving the repeated stress is selected. When a strong tensile stress is applied to the connecting member, the bag responds to the tensile force, and the compressive force accompanying this corresponds to the filler.

FIG. 5 is a cross-sectional view of another connecting member. The difference from FIG. 2 is that the base portion and the protruding portion have substantially the same width, and the bag 20a
And the partition member 20b of the connecting portion J are made of the same material, and a rectangular hollow portion is formed in the left-right direction of the rectangular partition member 20b by eliminating the whole rectangle. As a second embodiment, the bag 20
a and the partition member 20b are cut off to form a separate body as shown in FIG. That is, as shown in FIG. 2, a separate partition member 20b is interposed in the bag body 20a. However, the connecting material made of the same material by integral molding is limited to the material, for example, rubber, resin, etc., so it may not be used as a structural material having a large tensile force, but it is effective as a stretch joint and a waterproof material It is.

0b is installed on one side outside the bag as shown in the figure and on both sides (either of which can be applied to FIG. 2 or FIG. 5) or in the inside of the bag, that is, FIGS. It is good to adopt any one of the cases where it is put inside and installed as sewing or the like as J1 according to the use purpose of the connecting material. The base 21c is made of either flexible or inflexible.

FIG. 7 is a sectional view of another connecting member, which is a modification of FIG. The purpose of this shape is to make it easier to fit the connecting material into the recess. The figure combines the flexible bag 23d,
If necessary, glue the inside with a thin adhesive, and
At the position (2), the filling plate 25d is fitted to the middle side of the bag so as to easily fill the base 21d with the filling material, and sewing or the like J1 is performed. The filling plate 25d has an arbitrary shape, a semi-hollow shape or a hollow shape having holes at both ends of the plate to form a filling passage 24d for the filling plate. Although the partition members 10b are provided on both sides, the specifications may be the same as those in FIG. 6 if necessary. Filling plate 25
d is provided as needed, and depending on the material or shape of the bag, a semi-hollow shape and a hollow shape with holes, or an appropriate hollow in the bag as shown in FIG. 5 without using a shape material. It may be formed. When the base portion 21d, the protruding portion 22d, and the material of the bag body are different from each other, the joint portion may be held as shown in FIG.

FIG. 8 is a cross-sectional view showing members with a frame before connection. As shown, frames 53 and 54 are embedded in the recesses of members A and B, respectively, and connecting member 10 is inserted into base 54 of frame B of member B in the manner shown in FIG.
When the protruding portion 12 is fitted into the frame 53 of the member A, the partition member 10b is positioned near the boundary between the members A and B. This frame has an arbitrary shape. When this frame is provided, an arbitrary recess is easily formed, and when a large stress acts on both members A and B, the frame bears the stress. High joining structure can be obtained. Therefore, the frame may be provided on both or any of the members A and B according to the purpose of use of the member, and the anchor 24 may be provided at an appropriate location as necessary to further increase the adhesion strength between the frame and the member. . After the frames 53 and 54 are attached to the concrete form by an appropriate method, concrete is cast and buried.

In the above-described method of installing the connecting member, the connecting member is installed in the already formed recess or frame, but the present invention is a method of directly embedding the connecting member in the member B. It is an invention for reducing the labor for installing the connecting member and the material cost of the frame and the like.

In the case where the member B is made of concrete, for example, an extensible frame 40 which expands and contracts in the diameter direction of the pipe is prepared. The telescopic mold 40 is made to expand and contract by injecting air into a rubber tube, or in the case of a metal pipe, a part of the telescopic mold 40 is mechanically contracted in the inner space direction. Is mechanically contracted inward.
When returning to the original state, it can be restored by the reverse operation.

The telescopic frame 40 is inserted into the hollow of the base 31 of the bag 35a of the connecting member 30, restored to its original shape, installed on the concrete frame, and the concrete is cast on the member B. After curing, the expandable mold 40 is contracted and extracted in the axial direction by the method described above. The connecting member shown in FIG. 9A is made of the same material as the bag body and the partition member shown in FIG. 2 and integrally formed with an anchor, or formed integrally with the base 21 of the connecting member 20 shown in FIG. I'm using However, if the material of the base 31 of the bag 35a has adhesiveness to concrete, the anchor 34 of the base 31 or the unevenness for improving the adhesiveness is unnecessary.

In FIG. 9B, the bag 36a and the partition member 10b are made of different materials. If the bag cannot be formed integrally with the anchor, the bag is sewn with a thread, an adhesive or a thread 35c, etc., to form a connecting member 30 with an anchor 34c.
a, and installation on a concrete formwork is performed in the same manner as described above. If the connecting members 30 and 30a are cast directly into concrete as described above, the installation cost can be reduced. Needless to say, the connecting members without anchors shown in FIGS. 2 and 5 can be installed by the above-described method.

FIG. 10A is a cross-sectional view showing the shape of another connecting member and the installation state of the material. The connecting member 50 is in a state where the partition member 20b shown in FIG. 5 is hollow and folded, and the base 51 on the right side of the bag is bent. That is, the bag 50a of the connecting member 50 and the cutting material 50c are
Although the same material is integrally formed, the connecting member of the present invention may have the bag body 50a and the partition member 50c made of different materials (not shown) as described above. Therefore, the bag body 50a and the cutting member 50c are sewn with screws, screws, adhesives and sewing. The vicinity of the partition member 50b of the connecting member 50 is a member A
