Construction panel and connecting structure of construction panel and horizontal member

The present invention relates to a building panel and a connecting structure between the building panel and a horizontal member.

In Patent Document 1, a load-bearing wall structure having a large cross-sectional area is easily formed in a wall forming space defined between a structural column and a horizontal member to improve strength, airtightness, and appearance. The intended bearing wall structure is described. The bearing wall structure will be described with reference to the claims and reference numerals of this document. This load-bearing wall structure is formed with buried wood receiving grooves (2) in the four corners of the wooden prism column (1) in the longitudinal direction, and the wooden Joining grooves (3) are formed in the left and right side surfaces of the prismatic material (1) over the longitudinal direction, and the plurality of wooden prismatic materials (1) are attached to each other on the left and right sides forming the joining groove (3). The padding receiving groove (2) of the adjacent wooden prism column material (1) is brought into contact with the front and rear side surfaces of the wooden prism column material (1) on the longitudinal side of the contact surface. The joining groove (3) of the wooden prismatic material (1) to be matched is matched with the joining surface, and the buried tree (4) is inserted into the matching buried receiving groove (2), and the matching joining groove ( 3) Press-fit (5) connecting each wooden prism (1) into the bearing wall block. A wall-forming space defined by a pair of left and right structural columns (7) arranged at intervals and a pair of upper and lower horizontal members (8) horizontally mounted on the structural columns (7). (9) The load-bearing wall block (6) is built in, and the outer side surfaces of the left and right wooden prisms (1) forming the load-bearing wall block (6) are attached to the inner surface of the structural column (7). At the same time, each end face of each wooden prism column material (1) forming the bearing wall block (6) is attached to the inner side surface of the horizontal member (8), and the bearing wall block (6) is fastened with a fastener (10). Is a load-bearing wall structure fastened to the structural column (7) and the horizontal member (8).

JP 09-184197 A

The conventional load-bearing wall structure described above has the following problems.
1. In order to construct the load-bearing wall block (6), it is necessary to bond with an adhesive. Therefore, it is impossible to reuse the wooden prismatic material (1) constituting the load-bearing wall block (6). Have difficulty.
2. According to the combined structure of the load-bearing wall block (6), the structural pillar (7), and the horizontal member (8), the appearance is reduced, and the structure as shown in FIG. Cannot be built.

<Reason for Problem 1>
In the paragraph 0020 of the same publication, an adhesive is applied between the adjoining surfaces of adjacent wooden prismatic materials (1) and in each joining groove (3), and each wooden prismatic material (1) by press-fitting in employment (5) There is a description of strengthening the connection.
That is, in the prior art, if the adhesive is not bonded with an adhesive, the required strength cannot be obtained because the wooden prismatic material (1) and the hired fruit (5) can slide relative to each other in the thrust direction.
Therefore, adhesion with an adhesive is necessary.
The fastening hardware (10) does not contribute to the formation of the bearing wall block (6) itself.
In the paragraph 0019 of the same publication, the joining grooves (3) of the adjacent wooden prisms (1) are matched on the abutting surface, and the metal connecting the wooden prisms (1) to the matching joining grooves (3). There is a description that a load bearing wall block (6) is formed by press-fitting an actual product (5) made of wood or wood and the wooden prismatic material (1) is closely connected.
That is, since the bearing wall block 6 is completed without involving the fastening hardware (10), the fastening hardware (10) does not contribute to the formation of the bearing wall block (6) itself.
This means
In paragraph 0022 of the same publication, “This load bearing wall block 6 is defined by a pair of left and right structural columns 7 arranged at intervals as shown in FIG. 3 and a pair of upper and lower horizontal members 8 horizontally mounted on the structural columns 7. It is built in the wall-forming space 9 that has been formed. "
It is also clear from the description in paragraph 0024 of the publication that “the load-bearing wall block 6 thus assembled, the structural column 7 and the horizontal member 8 are connected to each other by the fastening hardware 10”. .
As can be seen from the above, in the prior art, it is necessary to bond with an adhesive to form the load-bearing wall block (6). Therefore, the wooden prism column material (1) constituting the load-bearing wall block (6) is re-used. It is impossible or difficult to use.

<Reason for Problem 2>
In the above-described conventional technique, the built-in load-bearing wall block (6), the structural column (7), and the horizontal member (8) are connected by the fastening hardware (10). In particular,
As described in the paragraph 0025 of the same publication, “As shown in FIG. 3, the seat plate 10 a of this wing plate bolt is attached to the outer surface of the structural column 7 at the joint portion of the horizontal member 8 and the structural column 7, and stands at the end thereof. The fastening bolt 10b provided is passed through the horizontal member 8 and tightened with a nut, and a joint member such as a fastening bolt 10c is passed through the structural column 7 from the outer surface of the structural column 7 through an attachment hole drilled in the seat plate 10a. It is pushed into the bearing wall block 6 ”.
According to such a coupling structure, since the fastening hardware (10) is exposed on the outer surface of the structural column (7), there is a problem that the appearance is reduced.
Further, since it is necessary to insert a joint material such as the fastening bolt 10c from the outer surface of the structural column 7 through the structural column 7 and into the load-bearing wall block 6, the structure shown in FIG. It cannot be built continuously.

The problem to be solved by the present invention is to provide a building panel in which a wooden square bar material constituting the building panel can be easily reused.
Moreover, it is providing the connection structure body of the building panel and horizontal member which can improve external appearance property and can construct | assemble a several building panel continuously in a horizontal direction.

In order to solve the above problems, the building panel of the present invention
An architectural panel that constitutes a wall,
A plurality of wooden square bars arranged adjacent to each other so as to contact the surfaces extending in the longitudinal direction and along a direction parallel to the wall surface of the wall;
A through hole penetrating these multiple wooden square bars in a direction perpendicular to the surface extending in the longitudinal direction and parallel to the wall surface of the wall;
A metal bolt that is inserted into the through hole so as to be along a direction parallel to the wall surface of the wall, and fastens the plurality of wooden square bars,
With
The metal bolt is press-fitted into the through hole, and the inner peripheral surface of the through hole and the outer peripheral surface of the metal bolt are in close contact with each other,
Of the plurality of wooden square bars, with respect to the axial direction of the metal bolt, the outer surface of the wooden square bar located on the outermost side is coupled to the head of the metal bolt or the metal bolt A recess for accommodating a nut is formed, and the length of the metal bolt is shorter than the length of the metal bolt in the axial direction of the wall made of the plurality of wooden square bars. And
According to this building panel, the longitudinal direction of the wooden square bar material is determined by the fastening action by the metal bolt inserted through the through hole penetrating a plurality of wooden square bar members in a direction orthogonal to the surface extending in the longitudinal direction. The surfaces extending in the direction can be brought into close contact with each other and can be firmly coupled. Moreover, since the inner peripheral surface of the through hole and the outer peripheral surface of the metal bolt are in close contact with each other, it is possible to reliably prevent the movement of the wooden square bars in the thrust direction.
Conventionally, in the construction field, the bolt is used only as a fastening member, and the inner diameter of the insertion hole of the bolt is formed larger than the outer diameter of the bolt. Therefore, for example, when two or more wooden square bars are fastened with bolts, it is necessary to separately provide a means for preventing the wooden square bars from moving in the thrust direction.
On the other hand, according to the present invention, the inner peripheral surface of the through hole and the outer peripheral surface of the metal bolt are in close contact with each other, so that it is possible to reliably prevent the wooden square bar members from moving in the thrust direction. Therefore, it is not necessary to separately provide a means for preventing movement in the thrust direction.
In other words, according to this building panel, it is possible to construct a building panel in which a plurality of wooden square bars are joined firmly and difficult to move in the thrust direction without using an adhesive, and through which the metal bolt is passed. By pulling out from the hole, the building panel can be broken down into wooden square bars.
Accordingly, the construction of the building panel is facilitated, and the reuse of the wooden bar material constituting the building panel is facilitated.

Furthermore, the metal bolt is press-fitted into the through-hole, and the inner peripheral surface of the through-hole and the outer peripheral surface of the metal bolt can be more securely adhered to each other. The movement in the thrust direction can be prevented more reliably.

In order to solve the above problems, the connecting structure of the building panel and the horizontal member of the present invention is:
A connection structure of the building panel and a horizontal member to which the building panel is coupled,
The metal inserted into the connecting hole provided in the core portion of the wooden square bar material and the horizontal member constituting the architectural panel is a connecting member for connecting the building panel and the horizontal member. A pipe made of metal and a drift pin driven in the orthogonal direction to this metal pipe,
The metal pipe is press-fitted into the connection hole, and an inner peripheral surface of the connection hole and an outer peripheral surface of the metal pipe are in close contact with each other.
According to this connecting structure of the building panel and the horizontal member, the metal pipe in the connecting member is used for the connection provided in the core part of the wooden square bar material and the horizontal member constituting the building panel. It is not exposed to the outside because it is inserted into the hole. Therefore, the appearance can be improved.
Moreover, since the drift pin driven in an orthogonal direction with respect to a metal pipe can be driven in from the panel surface side in the said building panel, it becomes possible to construct | assemble a several building panel continuously in a horizontal direction. .
And since the inner peripheral surface of the said connection hole and the outer peripheral surface of the said metal pipe are closely_contact | adhered, the positional accuracy with respect to the horizontal member of a building panel can be improved.

Further, the metal pipe is press-fitted into the connection hole, and the inner peripheral surface of the connection hole and the outer peripheral surface of the metal pipe can be more closely adhered to each other. The positional accuracy with respect to the horizontal member can be further increased.

(2a) is a cross-sectional view taken along 2a-2a in FIG. 1, and (2b) is a cross-sectional view taken along 2b-2b in FIG. The front view which shows other embodiment of the connection structure with the building panel and horizontal member which concern on this invention. The front view which shows an example of the wall structure which constructed | assembled the several panel 10 for construction continuously in the horizontal direction. 5-5 sectional drawing in FIG. (A) is a front view showing an example of a wall structure in which a plurality of building panels 10 ′ are continuously constructed in the lateral direction, and (b) is a bb cross-sectional view in FIG.

Hereinafter, an embodiment of a construction panel according to the present invention and a connection structure between the construction panel and a horizontal member will be described with reference to the drawings. In each figure, the same reference numerals are given to the same or corresponding parts.

As shown in FIG. 1, the building panel 10 of this embodiment is a building panel constituting a wall so that the surfaces 21 extending in the longitudinal direction are brought into contact with each other, and the wall surface of the wall. A plurality (8 in the figure) of wooden square bars 20 arranged adjacent to each other along a parallel direction, and the plurality of wooden square bars 20 are orthogonal to the surface 21 extending in the longitudinal direction. And the through-hole 22 penetrated in the direction parallel to the wall surface of the wall, and is inserted through the through-hole 22 along the direction parallel to the wall surface of the wall, and the plurality of wooden square bars 20 And a metal bolt 30 for fastening.
The inner peripheral surface of the through hole 22 and the outer peripheral surface of the metal bolt 30 are in close contact.
In addition, in FIG. 1, 40 is a connection member used for the connection structure of the building panel 10 and the horizontal member 50 which will be described later.

According to the building panel 10, the surfaces 21 extending in the longitudinal direction of the wooden square bars 20 can be brought into close contact with each other by the fastening action of the metal bolts 30 and can be firmly coupled. .
And since the internal peripheral surface of the through-hole 22 which penetrates the several wooden square bar material 20 in the direction orthogonal to the surface 21 extended in the said longitudinal direction and the outer peripheral surface of the metal volt | bolt 30 are closely_contact | adhering, The movement in the thrust direction S between the bars 20 can be reliably prevented.

Conventionally, in the construction field, the bolt is used only as a fastening member, and the inner diameter of the insertion hole of the bolt is formed larger than the outer diameter of the bolt. Therefore, for example, when two or more wooden square bars are fastened with bolts, it is necessary to separately provide a means for preventing the wooden square bars from moving in the thrust direction.
On the other hand, according to this embodiment, since the inner peripheral surface of the through hole 22 and the outer peripheral surface of the metal bolt 30 are in close contact with each other, the movement in the thrust direction S between the wooden square bars 20 is bolted. Therefore, there is no need to take another means for preventing movement in the thrust direction.

That is, according to this building panel 10, it is possible to configure the building panel 10 in which a plurality of wooden square bar members are joined firmly and difficult to move in the thrust direction without using an adhesive, and the metal bolt 30. Is extracted from the through hole 22, so that the building panel 10 can be disassembled into wooden square bar units.
Therefore, the construction of the building panel 10 is facilitated and the reuse of the wooden bar material constituting the building panel 10 is facilitated.

Further, according to the building panel 10, it is possible to improve the finish and adhesion by utilizing the smoothness of the wood, thereby not only the structural strength and the heat insulation performance, but also the airtightness and watertightness and It becomes possible to make a panel for building with fire prevention performance. Therefore, the wall that has been conventionally formed by mixing various materials can be made of almost a single material.

The metal bolt 30 is inserted in close contact with a through hole 22 penetrating a plurality of wooden square bars 20 in a direction orthogonal to the surface 21 extending in the longitudinal direction. For example, as shown in FIG. 1, screws may be provided at both ends and nuts 31 may be coupled to both ends. It is also possible to use a bolt having a head at one end. The location and the number of the metal bolts 30 can be set as appropriate. The ones in FIG. 1 are provided at equal intervals.
As shown in FIG. 1 and FIG. 2, of the plurality of wooden square bars 20, the outer side surface of the wooden square bar located on the outermost side with respect to the axial direction of the metal bolt 30 has the metal bolt 30. A recess for accommodating the nut 31 coupled to the head or the metal bolt is formed, and the length of the metal bolt 30 is made of a metal wall of a plurality of wooden square bars 20. It is shorter than the axial length of the bolt.

The threaded portion of the metal bolt 30 is provided only at the end portion (for example, both end portions) to which the nut 31 is coupled, and is not provided at the other portion (the contact surface with the inner peripheral surface of the through hole 22). It is desirable to make it. When a screw portion is provided in a portion of the outer peripheral surface of the metal bolt 30 that comes into contact with the inner peripheral surface of the through hole 22, the metal bolt 30 prevents the wooden square bar member 20 from moving in the thrust direction S. In addition, the threaded portion of the metal bolt 30 may easily bite into the inner peripheral surface of the through hole 22.

The number of the wooden square bars 20 to be provided side by side is arbitrary as long as it is two or more and can be fastened by the metal bolt 30. For example, as shown in FIG.
Moreover, the length of the wooden square bar material 20 can also be set suitably, and the opening for sash can also be formed combining a long wooden square bar material and a short wooden square bar material.

The metal bolt 30 is press-fitted into the through hole 22.
If comprised in this way, since the internal peripheral surface of the through-hole 22 and the outer peripheral surface of the metal volt | bolt 30 can be contact | adhered more reliably, the movement to the thrust direction of the wooden square bar materials 20 will be prevented more reliably. it can.

As shown in FIG. 2, by inserting an actual material 24 having the same length as the wooden square bar material 20 between the wooden square bar materials 20, the outer and inner sides of the building panel 10 are airtight. While being able to improve, a burning allowance fire resistance performance can be improved.
The actual material 24 may be wood, but the fire resistance can be further improved by using a non-combustible material such as a metal or a calcium plate.

According to the connecting structure of the building panel 10 and the horizontal member 50, the metal pipe 41 in the connecting member 40 includes the core portion of the wooden bar member 20 constituting the building panel 10 and the horizontal member. 50 is inserted into the connecting

holes

23 and 53 provided at 50 and is not exposed to the outside. Therefore, the appearance can be improved.

Moreover, since the drift pin 43 driven in the orthogonal direction with respect to the metal pipe 41 can be driven from the panel surface side (the front surface side or the back surface side in FIG. 1A) of the building panel 10, for example, FIG. As shown in FIG. 4, it becomes possible to construct | assemble the several panel 10 for construction continuously in a horizontal direction.
And since the inner peripheral surface of the connection holes 23 and 53 and the outer peripheral surface 42 of the metal pipe 41 are closely_contact | adhered, the positional accuracy with respect to the horizontal member 50 of the building panel 10 can be improved.

The thing shown in FIG. 1 provided the metal pipe 41 in the wooden square bar material 20 arrange | positioned at the both ends of the building panel 10, but the metal pipe 41 is provided in the wooden square bar material 20 other than both ends. The number of the building panels 10 is arbitrary. For example, the building panel 10 shown in FIG. 3 has ten wooden square bars 20 and is wider than that of FIG. 1, so that the connection strength with the horizontal member 50 is improved. The outermost wooden square bar 20 is provided with a long metal pipe 41 'to which a total of four drift pins 43 are connected at both the upper and lower ends, and the inner wooden square bar 20 is shown in FIG. The same metal pipe 41 is provided.

The wall structure shown in FIG. 4 is constructed by continuously building a plurality of building panels 10 in the horizontal direction. The building panel 10 shown in FIG. 1 and the building panel 10 shown in FIG. For convenience, the building panel 10 in FIG. 3 is alternately connected to the reference numeral 10 ′).
