Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structural material constituting columns and beams of a building, and more particularly to a technical field for joining structural materials made of concrete or similar materials. Applications of this structural material include structural materials such as general buildings, bridges, earth retaining structures, piles, and electric poles.

[0002]

2. Description of the Related Art In general, buildings in the fields of civil engineering and construction are mainly made of materials such as wood, reinforced concrete, steel frame and the like. In particular, the joints such as beams and beams, and beams and columns are complicated in structure, and are subjected to the most stress. Therefore, in order to finish with sufficient quality, manual work is inevitably increased. In particular, in the case of cast-in-place concrete, construction of this joint requires both manual and skilled labor.

[0003]

However, recently, due to labor shortages, the aging of skilled workers, and the cost consciousness of inexpensive finishing, there are many buildings constructed in a rough manner. On the other hand, as reported in the Great Hanshin Earthquake in January 1995, buildings built a while ago had a sufficient number of skilled workers at the time, but in Kobe, for example, 3
About 40% of buildings have collapsed due to construction errors. Thus, the quality of the buildings currently being built is apparently degraded as they are made by skilled workers at the level below that level.

[0004] In addition to the above-mentioned deterioration in quality, the design of the building itself has been simplified recently. For this reason, high-grade buildings such as those found in medieval European architecture have not been seen, and urban spaces have become scrambled. If the design of the building is not good like this, it will not be denied that the mind and mind of the people will be lost, the cultural level will be reduced, and the city will be ruined.

[0005] Therefore, the present invention provides a structural material that can be easily joined to a beam made of concrete or the like, a beam and a column, etc., even if a skilled worker is not used, and also enables a high-grade building. In addition, it is intended to provide a joining method thereof.

[0007] A joining method according to the present invention is a method for joining structural members having the above-described structure. After joining two or more ends of the structural members, the structural members should be joined. It is characterized in that a filler is injected into the hollow portion and solidified. Alternatively, a lid member is fixedly attached to the vicinity of the end, and after facing the ends of at least two or more of the structural materials to which the lid member is attached, a filler is injected into a space defined by the lid member. Then, the structural materials are joined to each other by solidification. In the latter joining method, it is preferable to use a lid member having an elastic body attached to the periphery.

Another joining method according to the present invention is a method for joining structural materials having the above-mentioned structure, wherein a bag is attached near an end of one structural material to be joined. After the structural material and the other structural material face each other, a filler is injected into the bag and expanded to join the structural materials. In addition, as a method of installing the bag, the bag is fixed to the other end of the reinforcing member or the cover, or the end of the expanding bag is stopped at a predetermined position through the cover, the reinforcing or the restraining member. It is preferable that the extension of the bag is restrained. Further, a connection frame may be provided at the other end of the bag. Further, when joining the structural material to be joined to the joint material, after abutting the structural material and the joint material, using any of the joining methods described above, filling and joining the filler material. do it.

If a strong material such as iron is used for the middle frame, the strength of the structural material is improved.

FIG. 9 shows another example of the structural material in which the middle frame is buried.
Shown in This figure is a perspective view showing the structural material in a cut state, so that the shape of the buried medium frame can be understood. This structural material 532 buries and kills the middle frame 632 in which the plurality of protrusions 632a are fixed inside on the inner surface of the hollow tube.
The projection member 632a may be a rod-shaped member, or the rod-shaped tip may be appropriately shaped. The material of the projection material 632a is the medium frame 63
It may be the same or different from 2. Note that, depending on the purpose of use of the structural material, the projecting material may be directly fixed to the inner surface of the hollow tube without using the middle frame.

FIG. 10 shows still another example of the structural material in which the middle frame is buried. Medium frame 6 embedded in this structural material 533
Numeral 33 is a rectangular tube formed by knitting a vertical bar and a horizontal bar. An anchor 633a is provided at an appropriate position to improve the adhesion to the hollow tube. The shapes of the vertical bar and the bar are arbitrary, and the material is the same as that of the above-mentioned medium frame. Further, a surface material 633b may be provided on the front side of the structural material 533 as a decorative material such as a tile or a reinforcing material for a structure. The surface material 633b is made of the same material as that of the middle mold frame 633, and may be partially or entirely stretched, or may be used as an outer mold frame and buried. Such surface materials are shown in Figs.
It can be used for structural materials shown in 9. Note that the medium-sized frame shown in FIGS. 9 and 10 may be further formed into a wavy shape or a spiral shape.

Further, the unevenness of the structural material may be provided on the entire hollow tube, or the unevenness 64 may be provided only in the vicinity of the end portion to be the joining portion, as in the structural material 54 shown in FIG.

Further, the structural material of the present invention can be formed into a form in which a mounting portion such as a groove for mounting an accessory such as a wall material, a door, or a sash is formed on the outside of the structural material when manufactured in a factory. . For example, in the structural material 55 shown in FIG. 12, one or two or more dovetail grooves 65 are provided on the outer surface as attachment portions so that a panel 66 or the like can be fitted therein. A projection 65a is provided on the opposite side. As described above, appropriate unevenness can be provided on the surface of the structural material in the vertical direction or the horizontal direction (not shown) as necessary. Furthermore, the outer surface of the structural material can be provided with various external shapes, including high-grade shapes such as sculptures and patterns.

As shown in FIG. 57, a structure in which a plurality of hollow tubes are integrated into a bundle may be used. Further, a cross-sectional shape as shown in FIGS. 15 and 16 may be used. Structural material 57 shown in FIG.
Reference numeral 1 denotes a shape obtained by removing the inner wall 2a from the structural material 57 in FIG. The structural material 572 shown in FIG. 16 has a shape obtained by removing the middle wall 2b from the structural material 571 in FIG. In the structural material of the type shown in FIGS. 13 to 16, it is not necessary to provide the unevenness 2 on all the inner surfaces, and a hollow portion having no unevenness may be provided depending on the purpose of use. Further, a part of the hollow portion is not hollow, and may have a solid structure in which concrete is cast in a factory.

The structural material comprising the hollow tube of the present invention is not limited to a hollow shape completely closed except at both ends. As illustrated in FIGS. 17 (A) to 17 (C), structural materials 58a, 58b, and 58c having cutouts 581 formed at one or more locations over a part or the entire length of the building material are also included. It is what is done. The hollow portion is provided with appropriate unevenness 2. The width of the cutout 581 and the size of the inner space width 582 depend on the purpose of use of the structural material and the shape of the unevenness 2, but it is preferable that the width of the cutout 581 is smaller than the inner space width 582. The bonding state with the material is assured.

FIG. 18 shows another example of the structural material. This structural material
Reference numeral 59 denotes a U-shape, and a corresponding middle frame 69 is fixed to the inner surface thereof. This medium frame 69 was buried and killed during concrete casting. A projection 69a is formed on the middle frame 69 by punching. Depending on the size, concrete flows out of the hole 69b after punching, so that the hole 69b is closed by an appropriate means as necessary. The middle frame that forms the protruding portion by this punching can also be used for structural materials of the type shown in FIGS. Also, medium-sized frames of the type shown in Figs.
It goes without saying that the medium frame 69 of the type shown in FIGS. 631, 632, 633 and FIG. 18 can be used for structural members of the types shown in FIGS.

Although various types of structural materials have been described above as examples, it is necessary to reinforce these structural materials depending on the shape and purpose of use. FIG. 19 shows an example of a structural material provided with such reinforcement. In this structural material 591, a reinforcing portion 591a is provided at an appropriate position inside the hollow tube. And the reinforcing part 591a
May have one or more openings 591b in its abdomen. The reinforcing portion 591a may be integral with the hollow tube, or may be formed by fitting a material of the same or different material. The space between the two reinforcing portions 591a may be filled with the mold 691.
Alternatively, a medium frame made of a material that can be incinerated or corroded may be used and removed after the concrete has hardened. Alternatively, use an air-inflated rubber medium frame as described above, and open the
You may take it out from 1b. Note that such a reinforcing portion can be provided by any of the types of structural materials described above.

Hereinafter, a method of joining the structural members as described above will be described.

In the embodiment shown in FIG. 20, two structural members 1
After the end faces 1 and 12 to be joined are matched, the filler A is injected from the filling port 12a. In this case, the filler A is
Fill the entire hollow space of 1 and 12. Further, if necessary, the temporary fixing member 13 is used for temporary fixing. As the filler, concrete, mortar, resin, ceramics, rubber and the like are used, and in addition, a non-ferrous metal such as zinc and aluminum or a molten iron can also be used. Further, iron, non-ferrous metal, organic or inorganic fiber, or the like mixed as a reinforcing material of the structural material 1 may be mixed into these fillers as needed. Which filler to use may be determined according to the use of the structural material. In the embodiment shown in FIG. 21, the lid member 14 is attached to the vicinity of the end of each of the structural members 11, 12 via the elastic member 14a around the lid member, and one of the structural members 12 has a hoop streak. After the reinforcing material 15 is inserted and fixed by the spacer 16 or the like, and the end faces are aligned, the filling material A is injected into the space defined by the lid member 14 from the filling port 12a. Is the hollow part of the structural material small?
When the device is installed deep, the auxiliary rod 17 is used as shown in FIG. This auxiliary rod 17 is fixed to one lid member 14.

The embodiment shown in FIG. 23 is a case where two structural members 11 and 12 in which the irregularities 6 are formed by spiral grooves are joined. The central portion of the lid member 18 in this example has a spherical surface bulging toward the end of each of the structural members 11 and 12 to be joined, and an adhesive having lubricity when uncured is applied to the outer periphery of the elastic member 18a. After the application, it is screwed to a predetermined position along the irregularities 6. After the adhesive is cured, the end faces of the structural materials 11 and 12 are aligned,
When the filler A is injected, the circumference of the central portion of the cover member 18 is expanded by the pressure at that time, and the elastic member 18a is brought into close contact with the unevenness 6. Therefore, the filling material A is
There is no leakage from the gap.

In the case where the air in the space where the filler A is injected does not escape from the joint gap in FIGS. 21 to 23, the cover member 18 or the structural members 11 and 12 are provided with appropriate size exhaust holes. A check valve or a filter 85 described later may be provided in the exhaust hole so that the filler A does not leak.

An example in which a joint is constructed with the structural material of the present invention using the above-described joining method will be described in order with reference to FIG.

First, the base plate 21 is fixed to the anchor 22 embedded in the foundation concrete. After welding the reinforcing member 15 to the base plate 21 as required, the lower pillar 23 made of a structural material is erected at a predetermined position and temporarily fixed. Thereafter, a predetermined amount of filler A is injected from the hole when the filling port 24 is provided in the lower pillar 23, or from the upper opening of the lower pillar 23 when the filling port is not provided, and 23 is fixed to the base plate 21. As another method, the reinforcing member 15 may be directly buried in the foundation concrete without providing the base plate 21 and the anchor 22. Next, a lid member attached to one end of the auxiliary rod 25 from the upper opening of the lower pillar 23
26 is inserted inside. In this example, a spring 27 or the like is provided around the lid member 26, the gap between the unevenness 6 is narrowed, and the elastic member supports the lid member 26,
When there is a possibility that the lid member 26 may be lowered by the weight of the filler A, the upper end of the auxiliary rod 25 may be held by an appropriate method.

Next, beams 30 made of a structural material are installed on both sides of the lower pillar 23 using a temporary fixing member 31 or the like as necessary. At this time, it is necessary to insert the lid members 33 arranged at both ends of the connecting rod 32 into the inside of the beams 30 on both sides,
After inserting deeply inside the beam 30 on one side so that it does not interfere with the installation of the beam 30 on the opposite side, install the beam 30 on the opposite side and return the lid members 33 to the respective predetermined positions. It is good to In addition, the lid member 33 is installed at the factory or on site,
If necessary, the reinforcing member 15 may be attached as described with reference to FIG. Finally, after installing the upper pillar 35, the lid members 26, 33,
Filling material A is injected from the filling port 36 into the space defined by 33 and solidified, and the columns 23 and 35 and the beams 30 and
Join 30. The beams 30 may be installed on three or four sides or more as needed, or may be installed in an oblique direction.

In the above example, no lid member is used for the upper column 35. This is because the filling material A is filled by gravity because the filling port 36 is provided above the predetermined filling range. However, it is a preferable method to fix the lid member above the filling port 36 and inject the filling material A with a predetermined pressure since the strength of the solidified filling material A can be increased. Further, the filler A may be filled in the upper space of the lower pillar 23 before the beam 30 is installed.

In the embodiment described above, as a method of attaching the lid member to the structural member in a fixed state, the elastic member attached to the periphery of the lid member is formed as a vehicle tire having a hollow inside, and the lid member is formed in a predetermined shape. Then, compressed air may be sent into the tire to expand it, and the elastic member may be brought into close contact with the unevenness of the structural material.

FIG. 25 is a sectional view for explaining another method of fixing the lid member inside the structural member in a fixed state. In this example, the lid member 40 has a ring-shaped bag body 43 attached to a rim frame 42 provided around a plate member 41, and an injection pipe 44 is connected to the rim frame 42. Structural material using auxiliary rod 17
When the filler B is injected into the bag 43 from the injection pipe 44 after the lid member 40 is inserted to a predetermined position in l, the bag 43 expands and engages with the irregularities 6 of the structural material 1. When the filler B is solidified, the lid member 40 is fixed. This method is uneven
Even if 6 has a complicated shape, the lid member 40 can be fixed in close contact with the inside of the structural material 1. At this time, the filler B is passed from the rim frame 42 to the bag 43 through the inside of the auxiliary rod 17 and the plate 41.
Can also be adopted.

In this manner, the lid member 40 is fixedly mounted in the structural member 1 and the ends of two or more structural members are butted by the above-mentioned method, and then the space is defined by the lid member 40. By injecting and solidifying the filler A, the structural members are joined to each other.

The bag 43 is made of rubber, ceramics, nylon,
A woven or insulative fabric formed from an organic or inorganic material such as aramid, carbon, or glass fiber, and may be coated with an organic polymer material. The bag 43 is attached to the rim frame 42 as shown in FIGS. 26 and 27, for example. The tip of the rim frame 42 can be opened in two as shown in FIG. 26 and is further hollow, and is fitted so as to wrap the core material 46 at the end of the bag body 43 as shown in FIG.
It is inserted into the hollow portion 45 of the rim frame 42, and both are fixed with screws 47. When the core material 46 is inserted into the hollow portion 45, if the elasticity of the hollow portion 45 is poor due to the material of the rim frame 42, the rim frame may be thinned as indicated by the dotted line 42a. When such a rim frame 42 is provided adjacent to the rim frame 48, as shown in FIG. 28, it is only necessary to add a square portion having a groove and a dovetail to the rim frame 48, and if necessary, only the square portion is provided. A plurality of them can be used in combination for adjusting the frame interval. As the material of the rim frame 42, a material such as iron, non-ferrous metal, resin, ceramics, or the like obtained by solidifying inorganic and organic fibers such as carbon fiber and aramid fiber is used.

In the joining method of the structural members using the lid members of the embodiments described above, it is necessary to fix the lid members inside the respective structural members in a fixed state. Next, the lid members are attached to only one side. An embodiment will be described.

FIG. 29 is a sectional view showing a structural member 71 in which a bag 73 is attached in a contracted state near an end to be joined. Bag
73 is sandwiched between the plate members 74 and 75 from the front and rear and is kept in a contracted state by the locking members 83 and 84 or the adhesive tape 83a. In the bag body 73, a chain,
A restraining member 77 such as a bendable string material such as a wire or a rope is stored in a contracted state. The middle part of the bag 73 is the rear plate 75
And is connected to an injection pipe 78 fixed to the injection pipe 78. Injection pipe
Another injection pipe 79 is provided in parallel with 78, and this injection pipe 79 is connected to a ring-shaped bag body 80 provided around the plate 75. The bag body 73 is held at the center of the hollow portion by spacers 81 and 82 provided at several places on the front plate member 74 and the rear plate member 75.

FIG. 30 shows this structural material 71 and another structural material.
FIG. 72 is a cross-sectional view showing a bonded state of No. 72. To join, the ends of both structural members 71 and 72 are abutted against each other, then filler B is injected into ring-shaped bag body 80 from injection pipe 79 to expand, and rear plate 75 is fixed. And then the injection pipe 78
The filling material A is injected into the bag body 73 to expand the bag. As a result, the bag 73 extends into the facing structural member 72 and simultaneously engages with the unevenness of the inner surface of the hollow portion, so that the filler A filled in the bag 73 is solidified and joined as shown in the drawing. Becomes The front plate 74 is provided with a filter 85 that allows air to pass through but does not allow the filler A to pass therethrough.
When A is press-fitted, the air remaining in the bag body 73 is released to prevent a cavity from being formed. Also, when filling material A is injected, locking members 83, 84 or adhesive tape
a comes off. The shape of the unevenness on the inner surface of the structural material 71 is arbitrary. Therefore, depending on the shape of the unevenness, the plate member 74 and the constraint member 77 may not be necessary if the plate member 74 is made thicker. 21 to FIG. 21 without increasing the thickness of the plate 74.
If the 23 lid members 14 and the like are used together, the extension of the bag body in the extending direction of the structural material can be restricted.

As described above, a method of using a single bag and injecting and solidifying a filler into the bag to join the structural members is performed, for example, in a case where a beam is provided at a joint between the lower column and the upper column. When the mouth becomes complicated, it becomes troublesome work in terms of joining the bags and holding the bags. In such a case, the bags may be joined using a connection frame 90 as shown in FIG. Connection frame 90
Consists of one or two or more frame bodies 91, the mounting angle of which is arbitrary, and is shown in FIGS. 26 and 27 in each frame body 91 taking an appropriate shape according to the number and angle of the joining points of the structural material The bag is attached in such a manner. Instead of using frame 91,
As shown in FIG. 32, the rim frame with square members 48 shown in FIG. 28 may be connected to each other by using the dovetail groove and dovetail, and assembled to form a connection frame 90.

A method of joining three or more structural members using such a connection frame will be described below. The connection shown in FIG. 33 is a case where beams in four directions are joined between the lower pillar and the upper pillar, and FIG. 34 shows a main part of the AA cross section of FIG. 33, and FIG. The lower half is shown in FIG. Lower pillar structural material
A connection frame 100 is installed at the upper end of 101, and a column main bar 103 and beam main bars 113 and 123 are arranged so as to fit within the connection frame 100.
The connection frame 100 is held by a main bar when there is a beam main bar or the like, and is held by a spacer 16 or the like when there is no beam bar. At this time, those main bars are reinforced by stirrup bars 104, 114, and 124. Next, a bag 1 is attached to each opening surface of the connection frame 100.
Attach one end of 05, 106, 115, 116, 125. When the bags are contracted along the main muscle and the other ends are supported by the nuts 106a attached to the ends of the main muscle, the bags can be prevented from moving in the extending direction of the structural material. In this way, the bag plays the role of the lid member 135. The nut 106a is screwed into a fixing plate 106b fixed to the beam main reinforcement 123. After that, the structural members 111, 112, 121, 122 of the beams are temporarily fixed on the structural members 101 of the lower pillars by using the temporary fixing members 131, and then the structural members 111, 112, 121, 122 of the beams are further fixed. The structural material 102 is installed, and the structural material 102 of the upper pillar is temporarily fixed using the temporary fixing member 131.

Therefore, a filling pipe is provided at the filling port 130 through the bag and the frame, and when the filler A is injected from the filling port 130, each of the bags 105, 106, 115, 116 and 125 expands. To adhere to the irregularities of each structural material. When the filler A is solidified, the structural members are integrally joined. In addition, if an inflatable material is added to the filler A, the pressure inside the bag body increases, so that the pressing force against the unevenness of the structural material increases. 33 to 35, a bag body is not used for the lower pillar 101, but a bag body is used for the upper pillar 102. As described above, for joining the column and the beam, the reinforcing material and the bag body may or may not be put in the structural material as necessary, or any of them can be combined, and an appropriate method can be selected depending on the purpose of the structural material. . It should be noted that in FIG. 35, the connection frame 100a has a rectangular rim frame 48 as shown in FIG.
This shows an example in which two pieces are used in an overlapping manner. Further, edges of a partition plate 16a provided with holes of an appropriate size as necessary are fitted into the dovetail groove and the protrusion of the connection frame 100a along four sides.
