[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for joining columns, beams, etc. in a building, a building by the joining method, and a technique for using the joining method in combination with a method for fixing a fixed end in a concrete drive. And buildings using that technology.

2. Description of the Related Art In a conventional wooden structure using a wooden material for its main frame in a main structure such as a column or a beam, a floor or a wall, the structure of the frame includes a column or a beam made of the wooden material. Various connections using a tenon, etc.
Not only is it necessary to form various types of joints such as hook joints, but in order to prevent loosening of each joint, it is necessary to reinforce it using binding hardware such as hardware, bolts, and scissors. Since the connection is a pin (joining), the brace is provided, and a structural strength is provided by, for example, providing a guide or a supporting column. In addition, in a new type of frame structure using a moment resistance joint by a bolt joint for a connection, the number of bolts increases, and the arrangement of the bolts is uneconomical, such as the cross-section of columns and beams being determined. ing. To illustrate the above, for example, as shown in FIG.
A box fitting 3 is used at a joint between the through pillar 1 and the second floor beam 2, and a short metal piece 5 is used along the trunk 4 and the through pillar 1. As shown in FIG. 7 (B), the connection between the trunk 4 and the through column 1 adopts a form as shown in the figure, and the connection uses a short metal piece 5 as a binding metal as shown. It is used to reinforce the connection. Further, as shown in FIGS. 7 (C) and 7 (D), for example, in the moment resistance joint between the column 1 and the beam 2, a large number of bolts 6 are driven into the joint. Note that FIG.
(D) is the figure which looked at FIG. 7 (C) from the side surface.

Further, conventionally, when it is desired to construct a simplified building such as a garage for an automobile, since the connection is a pin joint, for example, a boss 7 as shown in FIG. Although it is necessary to provide between the beam 1 and the beam 2, although not shown here, it is considered that it is desirable that the guide 7 is bolted to the column 1 as much as possible so as to have structural strength. ing. Further, as shown in FIG. 7B, in order to prevent deformation of the frame, it is desirable to provide diagonal brace 8 in a diagonal direction.

In such a main structure, in order to improve the structural strength of the frame, the main structure is not installed on the concrete foundation 9 as shown in FIG. As described above, it is conceivable that the wooden pillar 1 is buried directly in the concrete frame 9 such as the concrete foundation to obtain the fixed end of the wooden pillar 1. However, in the method of obtaining the fixed end,
While it is possible to obtain a fixed end with little backlash, and there is an advantage that it is simple and hassle-free,
When the wooden material 1 is directly buried in the concrete frame 9, the wooden material 1 absorbs alkali components in the ready-mixed concrete and deteriorates, or expands due to moisture. There is a problem that a gap is formed between them and the fixing is incomplete.

The joining member 10 has an inner diameter larger than the outer diameter of the column 1 and the beam 2. The gap between the column 1 and the beam 2 and the joint member 10 is filled with a concrete material 11 containing resin or cement, and the column 1 and the beam 2 are joined. At the time of the joining, the joining member 10 is
2, etc., may be fastened and fixed.

FIG. 2 (A) shows another example of a main portion of the joining method of the present invention, and FIG. 2 (B) shows a cross-sectional view of the same. As shown in FIG. 2 (A), a box-shaped joining member 10 is attached to a joint between the beams 2 to be joined. The inner diameter of the joining member 10 is
Is configured to be larger than the outside diameter. The gap between the beam 2 and the joining member 10 is filled with a concrete material 11 containing resin or cement, and the ends of the beam 2 and the beam 2 are joined.

As described above, the joining member 10 is attached to the joint between the column 1 and the beam 2 to be joined, and the concrete containing resin or cement is provided in the gap between the column 1 and the beam 2 and the joining member 10. The material 1 is filled and these pillars 1 and beams 2
The joining member 10 is attached to a joint portion where the beam 2 is to be joined or the beam 2 is to be joined, and the gap between the beam 2 and the joining member 10 is filled with a concrete material 11 containing resin or cement. By joining the ends of the beams 2 to each other, it is not necessary to form various joints using a tenon or the like and various joints such as complicated stitches as in the related art. In order to prevent each joint from loosening,
There is no need to use binding hardware such as bolts and braces, furthermore, there is no particular need for structural reinforcement means such as bracing, staking and stake columns, and furthermore, moment resistance joining by bolt joining to conventional connections. The construction cost can be reduced because a large number of bolts are not required as in the case of the frame structure using the stiffener.

Columns and beams are examples of members constituting a framework in a main structure of a building having a wooden structure, a steel structure, or the like used in the joining method of the present invention. For the columns and beams, for example, a wooden material is used. As the wood material, it can be used in the form of lumber, laminated wood, laminated wood, or other wood or wood processed material.
Those subjected to a treatment such as fire prevention can be used. In consideration of waterproofness, wood material is covered with waterproof resin coating,
Alternatively, a means of performing a waterproof treatment with a waterproof agent is effective. In addition, it is also effective to provide a protrusion such as a sheer connector on a wooden material. For these columns and beams,
A steel material or the like may be used. For example, a combination of a wooden material and a steel material may be used. When using steel on one side,
The joining member may be welded.

A joining member 1 used in the joining method of the present invention.
As an example of 0, a steel pipe can be exemplified as a typical example. The steel pipe is fitted with a U-shaped pipe having an open part, filled with a concrete material 11 containing resin or cement in the gap, and covered with an open part of the U-shaped pipe to form a steel pipe as appropriate. Can be changed.

The resin used in the bonding method of the present invention includes, for example, epoxy resin, urethane resin, acrylic resin and the like. Various additives such as a filler and a plasticizer can be added to the resin. As the resin to be used, it is preferable to use a resin having an adhesive property to a wood material or the like. As the resin, a wood adhesive containing a resin as a main component and various additives such as a filler and a plasticizer can be used. The resin can be used, for example, in a liquid form using a solvent or the like. Further, concrete materials including cement used include cement, concrete materials composed of fine aggregate and coarse aggregate,
A mortar that does not use coarse aggregate and a cement paste that does not use aggregate at all are exemplified. A concrete material comprising cement, fine aggregate and coarse aggregate is formed by mixing cement, fine aggregate, coarse aggregate and water. Examples of the aggregate include sand, crushed sand, gravel, crushed stone, and the like. The aggregate generally accounts for 60-80% of the concrete volume. Concrete materials, including cement, shrink in order to minimize the absorption of water into the wood and minimize the generation of excess water during hardening, and to minimize rattling of the wood. It is preferable that the degree of the degree is as small as possible. AE (entraine) may be added to the concrete material as necessary.
Various admixtures such as a dair) agent, a water reducing agent, and an accelerator (hydration reaction accelerator) can be added. A concrete material containing cement and a resin such as an epoxy resin, a urethane resin, and an acrylic resin may be mixed.

An example of the joining method according to the present invention is as follows. A T-shaped joining member is mounted on a column, a beam is inserted into a beam-side opening of the T-shaped joining member, and the column and the beam are connected to each other. The gap between the column and the beam may be filled with a concrete material containing resin or cement in the gap between the column and the beam.

Next, a description will be given of a technique of using the method of fixing the fixed end of the wood material to the concrete body in addition to the above joining method in the present invention, and a building using the technique. FIG. 3 shows an example of a main part configuration diagram of a method for obtaining a fixed end in addition to the above-mentioned joining method. That is, FIG.
As shown in the figure, the column 1 and the beam 2 are joined together,
An exterior member 13 having a diameter larger than the diameter of the column 1 is attached to a lower end (fixed end) of the column, and a concrete material 11 containing resin or cement is filled in a gap between the column 1 and the exterior member 13. An embodiment in which the lower end portion is filled and buried in the concrete frame 9 is shown. FIG.
FIG. 4A is a cross-sectional view of the lower end of the column 1 shown in FIG. As shown in the figure, the fixed end of the column 1 is fixed in a concrete frame 9 via a concrete material layer 11 containing resin or cement and an exterior member 13. That is, the exterior member 13 is provided outside the concrete layer 11 containing a resin layer or cement, and the concrete layer 11 containing the resin layer or cement is placed inside the exterior member 13 having one end opened and a bottom. The fixed ends of the columns 1, the concrete material layer 11 containing a resin layer or cement, and the exterior member 13 are embedded in the concrete frame 9. FIG. 4 (B) shows another example, and as shown in FIG.
And the fixed end of the column 1 and the resin layer 11 may be embedded in the concrete frame 9. In the above description, an example in which the present invention is applied to erecting a column is shown. However, the present invention can also be applied to a case where a fixed end of a beam or the like is embedded in a concrete frame 9 such as a concrete column or a wall.

FIG. 5 shows an example in which a garage 14 used in a garage of an automobile is constructed by using the above-mentioned construction method.
A T-shaped joint member 10 is attached to the joint between the column 1 and the beam 2 to be joined, and a concrete containing resin or cement is provided in a gap between the column 1 and the beam 2 and the joint member 10. A material (not shown) is filled to join the columns 1 and the beams 2, and the lower end of the columns 1 is placed in a concrete foundation 9 by a resin layer or a concrete material layer containing the resin layer or cement. An example is shown in which it is erected through the layer 11 and the exterior member 13.

As described above, according to the embodiment in which the fixed end is obtained in addition to the joining method, when joining the column 1 and the beam 2, various joints using a tenon or the like, complicated joints and the like are used in joining the column 1 and the beam 2. It is possible to exhibit the advantages of the joining method, for example, it is not necessary to form various kinds of joints, etc., and at the fixed end, even without using bolts or hardware as in the conventional example,
It is possible to make a fixed end with little backlash in structural mechanics,
There is no need for construction work, and it is not affected by the position of bolts, etc.
A fixed end with little backlash in structural mechanics can be made between the wooden material and the concrete frame without requiring a large number of bolts and making the cross section of the wooden material unnecessarily large. In addition, as compared with the method in which the fixed end of the wooden material 1 is directly buried in the concrete frame 9, the wooden material (post) 1 has a concrete material layer 1 containing cement inside the exterior member 13.
1, the gap between the concrete skeleton and the wood material in the drying shrinkage after the concrete is hardened is also affected only by the concrete material layer containing the cement, and the exterior member is formed by the concrete skeleton 9 Can be prevented from penetrating water into the wooden material 1, and the absorption of moisture can be stopped only from the concrete material layer 11 containing cement inside the exterior member. Further, in the garage 14 used in the garage of the automobile as described above, in the conventional example, since the column base and the connection between the column and the beam are pins, a bracing or a bearing wall is provided between the columns. Although it was necessary or required some kind of reinforcement, in the present invention, these are unnecessary, and these braces and the like become unnecessary, so that a wide space can be secured.

A typical example of the exterior member 13 used in the method for obtaining a fixed end of the present invention is a steel pipe, but it may be made of a material such as plastic, and the wooden material 1 is put into the concrete frame 9. Any material can be used as long as it can be fixed and a concrete material layer 11 containing resin or cement can be provided around the fixed end of the wooden material. As the wood material, the same material as that used in the joining method can be used. As the concrete material containing resin or cement used to obtain the fixed end, the same material as that used in the joining method can be used. In addition, concrete frame 9
As the concrete cloth foundation can be exemplified, for example,
Cement, water, fine aggregate, coarse aggregate, and those obtained by kneading, mixing and integrating admixture materials as needed are mentioned.

As a method for obtaining the fixed end of the wood material,
For example, a resin layer is attached to a fixed end (end to be fixed) of a wooden material and embedded in concrete before hardening, or a fixed end of the wooden material is inserted into a steel pipe of an exterior member. , Filled with a concrete material layer containing resin or cement, and embedded in the concrete before hardening, and furthermore, the steel pipe is installed in the hardened concrete, and the wood material is placed inside the steel pipe. And a concrete material layer containing resin or cement is poured into a gap between the wooden material and the steel pipe to form a concrete material layer containing resin or cement.

[Test Example] As shown in FIG.
6mmX1212mm), beam (38mmX1212mm)
88mmX1410mm) 2 is converted to a beam side square steel pipe (50m
mX100mmX176mm, thickness 3.2mm) 10 and pillar side square steel pipe (90mmX90mmX156.5m)
m, 3.2 mm in thickness) was formed into a T-shape, and the gap between the column and the beam and the rectangular steel pipe was filled with epoxy resin and joined. At the lower end of the column, a column-side square steel pipe (90 mm × 90 mm × 156.5 mm, thickness 3.2 mm) 10, a beam 2 is laid horizontally, and a load is applied to the center of the beam 2 to provide a frame structure. The specimen was subjected to a vertical force test. FIG. 6B shows the test results. As shown in the test results, the center displacement of the beam according to the present invention (A)
Is less than half of the displacement of (B) when both ends are pins, and is close to the displacement of the center of the beam of the frame (C) in which the beam and column are rigidly connected and the column base is fixed. By this. It can be seen that the T-shaped joint hardware increases the rigidity of the frame, and the failure is not the joint but the bending of the wood at the center of the beam. A method.

According to the present invention, a joining member is attached to a joint between a column and a beam to be joined, and a concrete material containing resin or cement is filled in a gap between the column and the beam and the joining member. If filled, it is possible to join with sufficiently high structural strength, and it is not necessary to form various joints such as drop joints and conventional joints such as potato joints as in the conventional example, and
There is an advantage that no metal fittings, bolts, braces, etc. for preventing the deformation of the frame are required, and no reinforcing means such as streaking, positioning and supporting columns are required. Also, wood material,
Use the fixed part as a strong fixed end in structural mechanics by fixing it in the concrete skeleton through a resin layer or through a resin material layer or a concrete material layer containing cement and an exterior member such as a steel pipe. Can be
The wood can be fixed to the concrete frame without being affected by the ready-mixed concrete, and there is no need to design special hardware according to the stress as in the case of fixing the wood with bolts. The construction is simplified, the cross section of the column is small, the cross section is not lost, the proof stress is high, and the design is favorable. Therefore, by using these joining methods and fixed ends together, it is possible to easily build a building such as a simplified automobile garage, and since there is no need to provide sidings and braces, it has a wide free space. A garage is obtained.
