Description

Technical Field

[0001] The present invention mainly relates to a joining structure, a joining member, and a joining method of wooden members capable of shortening the construction period of a building structure and suppressing construction costs in medium and large-scale wooden construction.

Background Art

[0002] In recent years, due to the revision of the Building Standards Law, the promotion of the use of domestic wood by the state and local governments, and the increase in SDGs and ESG investments, the wooden construction of medium and large-sized buildings has been progressing. Wooden construction is cheaper in construction cost than reinforced concrete construction or steel frame construction, and the weight of the building is also lighter. Therefore, it is possible to suppress costs even in the foundation work part, the payback period is short, and the comprehensive cost merit is large. Therefore, wooden construction is increasingly adopted for medium and large-sized commercial buildings. In such wooden buildings, in the joining part, the conventional framework construction method of joining wood by fitting using a tenon, etc., and using a strip metal or a fin plate bolt for reinforcement, or a metal construction method of joining with a drift pin or a bolt using a metal such as a steel plate at the joining part, and further, a method called GIR (Glued-in Rod), a method of inserting a steel bar into wood and filling it with an adhesive, an RH construction method, a Summit HR construction method, a home connector construction method, etc. There are various joining methods.

[0003] In the domestic housing industry, wooden construction is mainly used, and various building materials based on a 910 mm module are manufactured. The processing and production of structural members are also carried out with high-precision processing and incorporation of joining members by computer-controlled machine precutting, and the work at the construction site is short. In medium and large-sized wooden buildings, the utilization of various laminated woods and the development of joining metal members have been promoted, and a large-space wooden structure comparable to reinforced concrete construction or steel frame construction has become possible. However, compared with housing, it is difficult to modularize the building structure, and the working time at the construction site tends to be difficult to shorten. Also, ensuring the strength of the joining part is important.

[0004] Therefore, various technical proposals have been made in the past. For example, a technology has been disclosed whose title is "Method for joining building members, building structure, and method for constructing a building member joining structure" (see Patent Document 1). Specifically, the objective is to "shorten the construction period and reduce construction costs for a building structure equipped with a glue-in rod type building member joining structure," and the solution is as follows: "A box-shaped joining fitting that screws into the beam member is provided in the stepped portion of the beam member in which a metal rod is embedded, and a metal rod exposed on the outer surface is embedded in the column member, with an external thread provided on the exposed outer surface. At the construction site, a tall nut is screwed into the metal rod exposed in the space on the outer surface of the column member, and a bolt that passes through the hole in the beam member joining fitting is screwed into the opposite side of the tall nut, thereby joining the column member and the beam member joining fitting and connecting the beam member and the column member." The invention described in Patent Document 1 is a glue-in rod type joint structure for construction members, in which a metal rod is inserted into a hole in the building member in advance at the factory and fixed with adhesive, and the building members are connected to each other at the construction site by bolts and nuts connected via a connecting member, which is common to the technology of the present invention. However, the invention described in Patent Document 1 differs in that the connecting member is embedded in the beam member, the bolt and high nut are joined at only one place, the high nut is a separate component, and it corresponds to a rigid frame structure in only one direction.

[0005] Furthermore, a technology is disclosed whose title is "Joining structure for wooden columns and wooden beams and method for constructing the same" (see Patent Document 2). Specifically, the objective is to "provide a joining structure for wooden columns and wooden beams and a method for constructing the same that is easy to construct and prevents damage to the beams," and the solution is described as "a joining structure comprising a first wooden column member, a long material such as a steel rod fixed to a second wooden column member positioned above the first column member, and a joint that joins the wooden beam member. The end of the beam member is supported from below by the lower support portion of the joint and from above by the upper support fixed to the joint, so that cracks do not occur during an earthquake. In addition, since the bonding work of the lower end of the long material to the first column member is performed in the factory, the only bonding work required on site is the bonding work of the upper end of the long material to the second column member." However, the technology described in Patent Document 2 differs in that, although it can prevent damage to beams due to earthquakes, the connection between the column member and the beam member is not a glue-in rod type joint structure, which is thought to result in inferior pull-out strength of the beam member, and the bonding work of the upper end of the long material to the second column member must be carried out on-site as in the conventional method.

[0006] Furthermore, a technology is disclosed whose title is "Structure of a connecting part for wooden members" (see Patent Document 3). Specifically, the problem is to "provide a structure for a connecting part for wooden members for joining one wooden member to another member," and the solution is "a structure for a connecting part for wooden members for joining one wooden member to another member, wherein a hole or groove is formed in the wooden member, a rod-shaped member is provided in the hole or groove with adhesive interposed therebetween, the other end of the rod-shaped member protrudes to the outside of the wooden member, the rod-shaped member has a projection or a plurality of protrusions formed on one end side, and a covering portion is formed on the other end side of the projection or protrusion to prevent direct adhesion with the adhesive." However, the technology described in Patent Document 3, as seen in Example 21, involves inserting metal rods into holes in building members in advance at the factory and securing them with adhesive. While it shares some common ground with the present invention in that the building members are connected at the construction site using bolts and nuts via connecting members, the connecting members vary widely as seen in other examples. Furthermore, the main objective of the invention is to overcome the problem of low toughness when tensile force is applied in the opposite direction to the joining direction, which is a problem in conventional methods of joining wooden members, and to prevent damage to the connection part of the wooden members. The present invention has not yet solved the problem of the present invention. In addition, the technology described in Patent Document 3 differs from the present invention in that, regarding the structure of the connection part of the wooden members, it does not involve a structure using a combination of bolts and rods.

[0007] Furthermore, a technology titled "Joining Structure" has been disclosed (see Patent Document 4). Specifically, the objective is to "provide a joint structure for columns and beams that facilitates construction," and the solution is described as follows: "The joint structure is formed at the joint between upper and lower columns and left and right beams. The columns and beams are made of wood, and a lower joining member and an upper joining member are fixed to the upper end surface of the lower column and the lower end surface of the upper column, respectively, and the lower joining member and the upper joining member are joined. The end of the beam positioned to the side of the lower column on the column side and the lower joining member are joined using a beam joining member fixed to the end of the beam and a joining plate extending laterally from the lower joining member." However, although the technology described in Patent Document 4 has in common with the present invention in that it facilitates construction by connecting building members with bolts and nuts via connecting members at the construction site, it differs in that a connecting member is joined between the upper and lower columns, a beam joining member is joined to the connecting member, and it is not a glue-in rod type joint structure.

Embodiments for Carrying Out the Invention

[0020] The joining method of the vertical member and the horizontal member according to the present invention is characterized in that it adopts a configuration that enables the construction of a ramen structure that rigidly joins the joining part of the vertical member such as a column and the horizontal member such as a beam in a wooden building in a short construction period. Hereinafter, it will be described based on the drawings. However, it is not limited to the shape and configuration shown in such drawings, and can be changed within the range where the effects obtained as the creation of the technical idea of the present invention can be exerted.

[0021] FIG. 1 is a basic configuration explanatory drawing for explaining the basic configuration of the joining method of the vertical member and the horizontal member and the fitting according to the present invention. When indicating the direction in this document, the Z-Z direction shown in FIG. 1 is taken as the arrangement direction of the vertical member 10, and the X-X direction and the Y-Y direction are taken as the arrangement directions of the horizontal member 20 arranged on the horizontal plane where they are orthogonal.

[0022] Vertical members 10 are structural members that are erected vertically (in the vertical direction) in the framework of a building. They are members that are placed perpendicular to horizontal members such as beams, girders, and foundations. In wooden houses, these include through columns and intermediate columns. Through columns in wooden buildings are columns that run from the foundation to the eaves, one or more connected together, or columns that span each floor in multi-story buildings. They are generally structural members used in the corners of buildings. It is also preferable to use laminated timber with multiple core members that are stacked and compressed together. As a specific example, it is also preferable to use BP material with a cross-section of 600mm x 600mm, which is made by aligning four square core members with a cross-section of 150mm x 150mm vertically and four horizontally and compressing them together.

[0023] The horizontal members 20 are members that are installed in the horizontal direction of the building and transmit loads such as floors and roofs to the columns, and mainly bear bending stress in beams, girders, girders, and foundations. Furthermore, by making the connection relationship between the horizontal members 20 and the vertical members 10 rigid, a rigid frame structure is formed. It should be noted that there may be floors or levels where there are no floors or roofs and therefore no horizontal members 20 that transmit loads to the columns are required. As a specific example, it is also preferable to use BP material with a cross-section of 750mm x 450mm, which is made by aligning five square core members with a cross-section of 150mm x 150mm vertically and three horizontally and pressing them together.

[0024] The mounting rod 30 has a threaded portion formed on the outer circumference of a reinforcing bar, similar to a glue-in rod joint, and a tall nut 60 is screwed onto one end. It is inserted into a rod insertion hole 40 provided in the horizontal member 20 or vertical member 10.

[0025] The rod insertion hole 40 is a hole for inserting the mounting rod 30 into the vertical member 10 and the horizontal member 20. Specifically, if the diameter of the mounting rod is 20 mm, it is preferable that the rod insertion hole 40 be approximately 25 mm in diameter.

[0026] The adhesive 50 is used to securely fasten the mounting rod 30, which has been inserted into the rod insertion hole 40, to the surrounding wood by inserting it into the rod insertion hole 40 of the vertical member 10 and the horizontal member 20 and treating it with a resin adhesive. Epoxy resin adhesive or polyurethane resin adhesive can be used for the adhesive 50.

[0027] The Takanut 60, as its name suggests, is a nut that is longer in overall length than a regular hexagonal nut. It is also known as a long nut, joint nut, or connecting nut. Aside from its longer overall length, it basically conforms to the dimensions of a hexagonal nut, and hexagonal nuts and Takanuts of the same nominal diameter can generally be tightened with the same tools.

[0028] The connecting fitting 70 is a fitting for joining the vertical member 10 and the horizontal member 20. As shown in Figure 11, the connecting fitting 70 consists of a contact plate 100 that abuts against the contact surface 90 of the vertical member 10 and the horizontal member 20, and a frame 110 that connects them. Through holes 120 for fastening with fixing bolts 80 are provided in predetermined positions in the contact plate 100. As for the material, general structural rolled steel commonly used on construction sites is acceptable, but high-tensile steel plates with high specific strength are also suitable.

[0029] The fixing bolt 80 is a bolt that is screwed into a high nut 60 threaded at the end of the mounting rod. The fixing bolt 80 is a screw-type member that firmly connects the vertical member 10 and the connecting member 70 or the horizontal member 20 and the connecting member 70 by tightening the contact plate 100 of the connecting fitting 70 between itself and the high nut 60. Figure 8 shows an example of a hexagonal bolt 80 being an M20 x 75 mm fully threaded bolt, but other types of bolts with distinctive bolt heads, such as socket head cap screws or bolts with washers, or high-tension bolts made of high-tensile steel or stainless steel may also be used. In particular, high-tension bolts are made of high-tensile steel (tensile strength of 490 N / mm²). 2 More than 1,000N / mm 2The bolt is made of steel (less than 100%) and is designed so that the axial force of the bolt (the tensile force acting in the axial direction of the bolt when used to fasten structural materials with a bolt and nut) is uniform. For the same reason, it is also preferable to use high-tensile steel as the material for the mounting rod 30 and the high nut 60.

[0030] The contact surface 90 is the surface that contacts the contact plate 100, which is the contact surface of the connecting fitting, on the vertical member 10 and the horizontal member 20. It is also preferable to form a stepped surface for positioning on the vertical member 10 or the horizontal member 20.

[0031] The contact plate 100 constitutes the joining fitting 70, is arranged so as to sandwich the frame 110 between two plate-like bodies, and has an insertion hole 120 at a predetermined position.

[0032] As shown in Figure 11, the frame 110 is firmly fixed by welding, sandwiched between two contact plates 100. To ensure a predetermined length in the direction perpendicular to the load, for example, if the vertical member is 600 mm x 600 mm and the horizontal member is 450 mm x 750 mm, the length of the connecting fitting 70 in the direction perpendicular to the load could be approximately 200 mm. In this case, a fixing bolt with a length of 75 mm below the head is used, taking into consideration the need to secure space for tools. It should be noted that the frame 110 is not limited to a grid shape as shown in the embodiments in Figures 11(e) and 11(f) in cross-section. It may also be a rectangular frame, cylindrical frame, or honeycomb shape.

[0033] The through-hole 120 is a through-hole provided in the contact plate 100, through which a fixing bolt 80 is inserted and screwed into a high nut 60 located on the opposite side of the contact plate 100.

[0034] Figure 2 is an explanatory diagram illustrating the connection state of a one-way rigid frame in the connection method and fittings for connecting vertical and horizontal members according to the present invention. In this structure, the horizontal member 20 is rigidly connected to the vertical member 10 only in the X direction, while the other directions are maintained at a right angle with braces, etc. Specifically, as shown in Figure 2, a rigid frame is assembled in a portal shape and arranged in a tunnel shape, with the direction in which the horizontal member 20 is placed forming the rigid frame, and braces are used in the depth direction to prevent the portal shape from collapsing. Since it is difficult to create openings in the wall surface of the braces, this is an example of a structural form suitable for factories, warehouses, gymnasiums, etc. Note that braces (cross bracing), load-bearing walls, beams in the Y direction, etc. are omitted.

[0035] Figure 3 is an explanatory diagram illustrating the connection state of a two-way rigid frame in the vertical member and horizontal member connection method and fittings according to the present invention, showing that the horizontal member 20 is rigidly connected to the vertical member 10 in both the X and Y directions. Specifically, as shown in Figure 3, a major feature of the two-way rigid frame construction method for wooden structures is that it enables rigid connection in two directions, similar to steel structures. Wooden structures generally require bracing and load-bearing walls, so public facilities requiring large openings and large spaces have mainly been constructed using steel or reinforced concrete. However, by using the vertical member and horizontal member connection method and fittings according to the present invention, the connection between the vertical member 10 and the horizontal member 20 can be made into a rigid frame structure similar to that of reinforced concrete structures, eliminating the need for bracing and load-bearing walls, and allowing the load to be supported by the vertical member 10 and the horizontal member 20 alone. This demonstrates that it is possible to create open and spacious spaces even in wooden structures.

[0036] Figure 4 is a flowchart showing the steps of the joining method for vertical and horizontal members according to the present invention. As shown in Figure 4, the procedure for each step of the joining method for vertical and horizontal members according to the present invention is shown. It consists of the rod insertion hole drilling steps A and A2, the mounting rod installation steps B and B2, the joining fitting installation steps C and C2, and the joining steps D and D2 of the vertical and horizontal members. The contents of each step are described below.

[0037] Figure 5 is a process diagram illustrating the rod insertion hole drilling process A and A2 in the joining method of vertical and horizontal members according to the present invention. Figure 5(a) shows the vertical member 10 from the front, Figure 5(b) shows the vertical member 10 from the side, Figure 5(c) shows the horizontal member 20 from the side, and Figure 5(d) shows the horizontal member 20 from the front.

[0038] Rod insertion hole drilling process A is a drilling process that drills rod insertion holes 40 in the ends of the vertical member 10 and the horizontal member 20 for inserting the mounting rod 30, as shown in Figure 5. Specifically, if the diameter of the mounting rod 30 is 20 mm, the hole is drilled to an inner diameter of approximately 25 to 27 mm. The reason for drilling the hole diameter to be 20% to 25% larger than the rod diameter is to improve the ease of installation in mounting rod installation process B by fitting the rod in a loosely fitted state, and to ensure the fluidity of the viscous adhesive. The depth of the hole is determined according to the length of the mounting rod 30.

[0039] Rod insertion hole drilling process A2 is a drilling process that drills rod insertion holes 40 for inserting mounting rods 30 in two directions perpendicular to the horizontal direction of the vertical member 10 and at the end of the horizontal member 20. The specific dimensions are the same as those of rod insertion hole drilling process A.

[0040] Figure 6 is a process diagram illustrating the state of mounting the mounting rod in the mounting rod mounting process B and B2 of the joining method for vertical and horizontal members according to the present invention.

[0041] Figure 7 is a process diagram illustrating the adhesive filling method in the mounting rod installation process B and B2 of the joining method for vertical and horizontal members according to the present invention.

[0042] Mounting rod installation process B, as shown in Figure 6, involves inserting the mounting rod 30, which has a high nut 60 screwed onto it, into the rod insertion hole 40 drilled in the vertical member 10 and the horizontal member 20 in rod insertion hole drilling process A, and as shown in Figure 7, pressing adhesive 50 into the mounting rod 30 from one end to the other end to fill it, thereby mounting the mounting rod 30.

[0043] Mounting rod installation process B2 involves inserting mounting rods 30, which have high nuts 60 screwed into rod insertion holes 40 drilled in rod insertion hole drilling process A2 at two directions perpendicular to the horizontal direction of the vertical member 10 and at the ends of the transverse member 20, and then injecting adhesive 50 to attach the mounting rods 30, similar to mounting rod installation process B.

[0044] Figure 8 is a process diagram illustrating the joining fitting attachment process C-C2, which involves attaching a joining fitting to one side of a vertical or horizontal member according to the present invention.

[0045] Step C, the process of attaching the connecting fitting, is the process of attaching the connecting fitting 70 to either the vertical member 10 or the horizontal member 20 using a fixing bolt 80 via a high nut 60 provided at one end of the mounting rod 30, as shown in Figure 8. Although Figure 8 illustrates the case where the connecting fitting 70 is attached to the vertical member 10 first, the connecting fitting 70 may also be attached to the horizontal member 20 first.

[0046] The joining fitting installation step C2 is a step in which the joining fitting 70 is attached to the vertical member 10 in two directions perpendicular to the horizontal direction or to the horizontal member 20 using fixing bolts 80 via a high nut 60 provided at one end of the mounting rod 30. Although Figure 8 illustrates the case where the joining fitting 70 is attached to the vertical member 10 first, the joining fitting 70 may also be attached to the horizontal member 20 first.

[0047] Figure 9 is a process diagram illustrating the joining process D and D2 of a vertical member and a horizontal member, which connects a joining fitting attached to one vertical member or horizontal member with the other vertical member or horizontal member according to the present invention.

[0048] The joining process D of the vertical member and the horizontal member is a process of fastening the high nut 60, which is provided at one end of the mounting rod 30 fixed to the other vertical member 10 or the horizontal member 20, and the joining fitting 70, which was attached in the joining fitting attachment process C, with the fixing bolt 80.

[0049] The joining process D2 of the vertical member and the horizontal member is a process of fastening the high nut 60, which is provided at one end of the mounting rod 30 fixed to the other vertical member 10 or the horizontal member 20, and the joining fitting 70, which was attached in the joining fitting attachment process C2, with the fixing bolt 80.

[0050] Figure 10 is an explanatory diagram illustrating the joining state of a vertical member and a horizontal member rigidly joined using the joining method and fittings according to the present invention. It shows a state in which the horizontal member 20 is rigidly joined to the vertical member 10 in two directions by the joining fittings 70.

Figure 11(a) is a plan view, Figure 11(b) is a left side view, Figure 11(c) is a front view, Figure 11(d) is a right side view, Figure 11(e) is a cross-sectional view of ee, and Figure 11(f) is a cross-sectional view of ff. In this embodiment, the frame 110 connecting the two contact plates 100 is shown in a grid shape, but it is not limited to this grid shape, and may be a rectangular frame, cylindrical frame, or honeycomb shape. [Industrial applicability]

[0052] The joining method, joining hardware, and joining hardware for vertical and horizontal members according to the present invention are suitable for medium- and large-scale facilities such as schools, hospitals, gymnasiums, and libraries, as well as multi-story wooden houses. Compared to conventional reinforced concrete and concrete structures, they are lighter and contribute to the effective use of domestically produced timber, and are therefore considered to have high industrial applicability.
