In the conventional wooden structure, since the gap is formed between the bolt hole formed in the column member or the beam member and the through bolt, the rigidity of the beam-column joint is not sufficient. Further, in the conventional wooden structure, in a building in which each space is divided by a large number of boundary walls, it was necessary to construct a large number of wall portions on site.

The present invention has been made in view of the above-mentioned problems, and provides a wall-type structure in a wooden structure in which the joints of the main members have sufficiently high rigidity and site construction of the wall structure is unnecessary. With the goal.

[0005]

In order to solve the above problems, in the present invention, a wooden beam member and a wooden wall member are provided, and the beam member and the wall member are the beam member and the beam member. There is provided a wall-type structure in a wooden structure, which is rigidly joined via a rod-like member embedded in the wall member.

According to a preferred aspect of the present invention, the rod-shaped member is a reinforcing bar having a predetermined length, and a part of the reinforcing bar is integrated with the beam member in a hole formed in the beam member. The remaining portion of the reinforcing bar is integrally embedded with the wall member in the hole formed in the wall member.

Further, it is preferable that the wall member is rigidly joined to the base member through a reinforcing bar provided integrally with the wall member in the wall member. Furthermore, it is preferable that the beam member and the wall member are made of a wood structural material.

BEST MODE FOR CARRYING OUT THE INVENTION The wall-type structure in the wooden structure of the present invention includes, as main structural members, a beam member and a wall member made of, for example, a wooden structural material. The beam member and the wall member are rigidly joined via a rod-shaped member such as a deformed reinforcing bar embedded in both members. More specifically, a part of the reinforcing bar is integrally embedded in the hole formed in the beam member with the beam member, and the remaining part of the reinforcing bar is integrally embedded in the hole formed in the wall member with the wall member. Has been done.

Therefore, in the wall-type structure of the present invention, the beam member and the wall member manufactured in advance at the factory may be carried into the site, and the beam member and the wall member may be bonded to each other via the reinforcing bar in the field. As a result, on-site construction of the wall structure is not required, which is particularly advantageous for buildings in which a relatively narrow space is divided through a large number of boundary walls, such as a detached house or an apartment house. . Further, in the wall-type structure of the present invention, since the joint portion of the main members has sufficiently high rigidity, it is possible to secure sufficiently high reliability as a structure.

Embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a diagram schematically showing the overall structure of a wall-type structure in a tree structure according to an embodiment of the present invention. FIG.
The wall type structure is an example in which the present invention is applied to a three-layered rigid frame structure.

In the wall type structure shown in FIG. 1, a wall member 2 and a beam member 3 are provided on a concrete cloth foundation 1 cast in the ground.
A wall type rigid frame structure is formed by and. In FIG. 1, the subscript a is attached to the first layer member, the subscript b is attached to the second layer member, and the subscript c is attached to the third layer member. In addition, the wall members 2a to 2c and the beam members 3a to 3c.

FIG. 2 is a view for explaining the principle of joining the main members of the present invention, and is an enlarged cross-sectional view illustrating the configuration of the joining portion of two beam members arranged in a straight line. As shown in FIG. 2, in this embodiment, the beam members 11 and the beam members 12 arranged in a straight line are, for example, both beam members 11 and 12.
Of a pair of deformed reinforcing bars 21a and 21 integrally embedded in the
It is rigidly joined via b. More specifically, the beam member 11 has a pair of reinforcing bar insertion holes 22a and 22b, and the beam member 12 has a pair of reinforcing bar insertion holes 23a and 2b.
3b is formed. The deformed bar 21a is inserted into the reinforcing bar insertion holes 22a and 23a,
b is inserted in the reinforcing bar insertion holes 22b and 23b.

In this state, the deformed reinforcing bar 21a and both beam members 11 and 12 are integrally formed by injecting a filler such as epoxy resin into the reinforcing bar insertion holes 22a and 23a through the injection hole 24a. Can be joined. In this case, the rebar insertion hole 2 is inserted through the confirmation hole 25a.
It is preferable to visually confirm whether or not the epoxy resin is sufficiently filled in 2a and 23a. Similarly, the rebar insertion holes 22b and 2 are inserted through the injection holes (not shown).
By injecting an epoxy resin into 3b, for example,
Deformed bar 21b and both beam members 11 and 12 can be integrally joined. In addition, it is possible to visually confirm whether or not the epoxy resin is sufficiently filled in the rebar insertion holes 22b and 23b through a confirmation hole (not shown).

Thus, a joint having a sufficiently high rigidity is formed between the beam member 11 and the beam member 12. Unlike the conventional joint using the through bolt, the joint thus formed has no unnecessary protrusion and has very strong resistance to bending moment and shearing force. It should be noted that FIG. 2 illustrates a joint portion of two beam members arranged in a straight line. However, in this embodiment shown in FIG. 1, between the beam member 2 and the wall member 3, and between the wall member 3 and the wall member 3.
2 and also between the wall member 3 and the base member 1.
A rigid joint is formed based on the principle shown in. In addition,
It goes without saying that the diameter and the number of reinforcing bars in each joint are determined based on a predetermined structural calculation.

FIG. 3 is a perspective view showing the structure of the joint between the beam member and the wall member. As shown in FIG. 3, when joining two wall members 32a and 32b to one beam member 31, use reinforcing bars 33a to 33c that penetrate the beam member 31 and reach the two wall members 32a and 32b. You can In this case, the lower wall member 32a includes the reinforcing bars 33a to
It is preferable that the 33c be brought to the site in a form pre-embedded in the factory. In this case, the lower wall member 32a carried into the site is built in, and the beam member 31 and the upper wall member 32b are built so that the reinforcing bars 33a to 33c protruding from the lower wall member 32a pass through. Thus, by injecting the epoxy resin into the predetermined reinforcing bar insertion hole formed in the beam member 31 and the upper wall member 32b, it is possible to easily and reliably construct the rigid joint on site.

FIG. 4 is a perspective view showing a structure of a joint portion of two beam members which intersect each other. As shown in FIG. 4, when the beam member 42 is cross-joined to one end of the beam member 41, both members may be rigidly joined via the beam member 41 and a pair of reinforcing bars 44 embedded in the beam member 42. it can. Also, when the beam member 43 is cross-joined to the center of the beam member 41, both members can be joined via the beam member 41 and the pair of reinforcing bars 45 embedded in the beam member 43. In this way, the two beam members can be easily and reliably field-bonded at the intersection of the beam members including the projecting corner portion and the entering corner portion.

Further, FIG. 5 is a partial cross-sectional view showing the structure of the joint between the wall member and the base member. In FIG. 5,
Only the basic part is shown in a sectional view. As shown in FIG. 5, when the wall member 52 is joined to the reinforced concrete cloth foundation 51 cast in the ground, the wall member 52 and the cloth foundation 51.
It is possible to use the reinforcing bars 53a to 53c that penetrate the.
In this case, it is preferable that the wall member 52 be carried into the site with the reinforcing bars 53a to 53c pre-embedded in the factory. At the site, the cloth foundation 51 is provided with sleeves 54a for inserting the reinforcing bars.
54c is formed. Then, the wall member 52 is built on the cloth foundation 51 while inserting the reinforcing bars 53a to 53c into the sleeves 54a to 54c. Next, by packing the non-shrink mortar 55 in the sleeves 54a to 54c, the wall member 5
2 can be fixed on a reinforced concrete cloth foundation 51.

FIG. 6 is a perspective view showing a typical overall structure of the wall member. As shown in FIG. 6, a reinforcing bar 61 for joining is attached to the upper and lower ends of a load bearing panel 60 that constitutes a wall member.
Preferably, and 62 are each pre-filled at the factory. As described above, the load bearing panel 60 is a wall member integrally formed of a wooden structural material such as LVL. When the load bearing panel 60 constitutes, for example, a wall member of the first layer, the reinforcing bar 62 protruding from the lower end is inserted into the sleeve formed on the cloth foundation, and the reinforcing bar 61 protruding from the upper end is the beam member of the corresponding first layer. It is inserted into the reinforcing bar insertion hole formed in. Thus, by using the load bearing panel 60 in which the reinforcing bars 61 and 62 are embedded in advance, the erection can be performed quickly and safely.

The load-bearing panel 60 has reinforcing bars 61 and 6
It is also possible to carry the load-bearing panel 60 into the field with the reinforcing bar insertion hole formed, without embedding 2.
In this case, cut the LVL into a predetermined shape at the factory,
A load-bearing panel can be manufactured simply by making a hole for the reinforcing bar insertion hole. In the field, it is not necessary to process the loaded load-bearing panel, and only the rigid joint via the reinforcing bar is formed as described above.

Unlike the wall panel in the two-by-four (2'x4 ') construction method, the load-bearing panel 60 made of LVL is an industrial product whose structural specifications and mechanical properties are clearly defined. Therefore, the load bearing panel 60 has much higher load bearing strength (strength) than the same type panel of the two-by-four construction method. As a result, it is possible to realize a building plan with a high opening ratio even with a three-story wall type structure. The height H of the load bearing panel 60 is determined based on the desired shape of the building space and the like. The length L of the load bearing panel 60 is determined based on the desired shape of the building space and the desired structural bearing strength. Further, the thickness T of the load bearing panel 60 is determined based on a desired desired structural strength, a desired heat insulating property, and the like.

FIGS. 7A to 7C are plan views showing a state in which two load bearing panels are joined. As shown in FIG. 7, the two load bearing panels joined to each other through the reinforcing bars have a characteristic of being able to stand by themselves. This property is very advantageous from the viewpoint of workability and cost of erection. As for the floor, a wooden floor may be adopted, or in order to secure living performance, concrete may be placed after laying a deck plate on the beam member.

[0022]

As described above, according to the present invention, it is only necessary to join the beam member and the wall member, which have been carried into the site, through the reinforcing bar on the site, so that the construction of the wall structure on the site is not necessary. Therefore, the wall-type structure of the present invention is particularly advantageous for a building in which a space is divided through a large number of boundary walls.
