Description

[Technical field]

[0001] The present invention relates to a joining structure, joining member, and joining method for wooden members that can shorten the construction period and reduce construction costs of architectural structures, mainly in medium- to large-scale wooden construction. [Background technology]

[0002] In recent years, wooden construction is becoming more common for medium- to large-sized buildings due to revisions to the Building Standards Act, the promotion of the use of domestic timber by the national and local governments, and increased investment in SDGs and ESG. Wooden construction is cheaper to build than reinforced concrete or steel-frame construction, and the weight of the building is light, so there is a possibility of reducing costs even in the foundation work part, and the depreciation period is short, so there are many overall cost benefits, and so wooden construction is increasingly being used for medium- to large-sized buildings for business use. In such wooden buildings, various joining methods exist, such as the traditional frame method, in which timber is joined by joining it together using "tenons" and the metal method, which uses metal such as steel plates at the joints and joins them with drift pins and bolts, and even a method called GIR (Glued-in Rod), in which a steel rod is inserted into the timber and filled with adhesive, the RH method, the Summit HR method, and the Home Connector method.

[0003] In Japan's housing industry, wooden construction is the norm, and a variety of building materials are manufactured based on the premise of a 910mm module. The processing and production of structural components is also performed with high precision using computer-controlled precut machines, and the installation of connecting components is performed with a short amount of time on-site. For medium to large wooden buildings, the use of various laminated timber materials and the development of connecting metal components are progressing, making it possible to create large wooden structures comparable to reinforced concrete and steel frame structures. However, compared to houses, modularizing building structures is difficult, and it tends to be difficult to reduce work time on site. Ensuring the strength of the joints is also important.

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

[0005] Also, a technology entitled "Joint structure between wooden pillar and wooden beam and method for constructing same" has been disclosed (see Patent Document 2). Specifically, the problem is to "provide a joint structure between wooden pillar and wooden beam that is easy to construct and can prevent damage to the beam and a method for constructing same", and the solution is described as "the joint structure includes a first wooden pillar member, a long material such as a steel rod fixed to a second wooden pillar member arranged above the first pillar member, and a joint body to which the wooden beam member is joined. The end of the beam member is supported from below by the lower support part of the joint body and from above by the upper support body fixed to the joint body, so that no cracks will occur during an earthquake. Also, the bonding work of the lower end of the long material to the first pillar member is performed in a factory, so the bonding work on site is only the bonding work of the upper end of the long material to the second pillar member." However, while the technology described in Patent Document 2 can prevent damage to beams due to earthquakes, etc., it differs in that the connection between the column member and the beam member is not a glued-in rod type joint structure, which is thought to result in inferior pull-out strength of the beam member, and in that the work of gluing the upper end of the long material to the second column member must be carried out on site, as in the conventional case.

[0006] Also, a technology has been disclosed with the title of the invention "Structure of a connection part of wooden members" (see Patent Document 3). Specifically, the problem is to "provide a structure of a connection part of wooden members for joining one wooden member to another member", and the solution is "a structure of a connection part of wooden members for joining one wooden member to another member, in which a hole or groove is formed in the wooden member, a rod-shaped member is provided in the hole or groove with an adhesive interposed therebetween, the other end of the rod-shaped member protrudes outside the wooden member, and the rod-shaped member has a protrusion or a plurality of protruding parts formed on one end side and a covering part formed on the other end side of the protrusion or protruding parts to prevent the rod-shaped member from being directly bonded to the adhesive." However, the technology described in Patent Document 3 has something in common with the present invention in that, as shown in Example 21, metal rods are inserted into holes in building components and fixed with adhesive in advance at a factory, and building components are connected at the construction site with bolts and nuts via connecting members, but the connecting members are diverse as shown in other examples, and the main purpose of the invention is to solve the problem of low toughness when a tensile force is generated in the opposite direction to the joining direction, which is a problem with conventional methods of joining wooden components, and to prevent damage to the connecting parts of the wooden components, and does not solve the problems of the present invention. Also, the technology described in Patent Document 3 differs from the present invention in that the structure of the connecting parts of wooden components is not a structure based on a combination of high bolts and rods.

[0007] Also, a technology entitled "Joint Structure" has been disclosed (see Patent Document 4). Specifically, the objective of the present invention is to provide a joint structure between columns and beams that facilitates construction, and the solution is as follows: "The joint structure is formed at the joints between the upper and lower columns and the left and right beams. The columns and beams are made of wood, and a lower joint member and an upper joint 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 joint member and the upper joint member are joined. The end of the beam arranged on the side of the lower column is joined to the lower joint member using a beam joint member fixed to the end of the beam and a joint plate extended laterally from the lower joint member." However, the technology described in Patent Document 4 has some commonalities with the present invention in that building components are connected to each other by connecting bolts and nuts via connecting members at the construction site to facilitate construction, but it differs in that connecting members are joined between the upper and lower columns, beam joint members are joined to the connecting members, and the joint structure is not a glued-in rod type.

FIG. [Figure 11] FIG. 2 is an explanatory diagram of the connecting fitting configuration, illustrating an embodiment of the basic shape of the connecting fitting between vertical members and horizontal members according to the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] The main feature of the method for joining vertical members and horizontal members according to the present invention is that it adopts a structure that enables the construction of a rigid frame structure in a short construction period, in which the joints between vertical members such as columns and horizontal members such as beams in a wooden building are rigidly joined. The method is described below with reference to the drawings. However, the shape and structure are not limited to those shown in the drawings, and may be modified within the scope of the effect of the invention as a creation of the technical idea.

[0021] Fig. 1 is a basic configuration explanatory diagram for explaining the joining method of vertical members and horizontal members and the basic configuration of the joining fittings according to the present invention. Note that when indicating directions on this page, the ZZ direction shown in Fig. 1 is the arrangement direction of the vertical members 10, and the XX direction is the arrangement direction of the horizontal members 20 arranged on the horizontal plane where the XX direction and the YY direction are perpendicular to each other.

[0022] The vertical members 10 are structural members that are erected vertically in the framework of a building, and are members that are placed at right angles to horizontal members such as beams, girders, and foundations. In wooden houses, there are through columns and pipe columns. Through columns are columns that are connected to each other in wooden buildings, and columns that are installed across each floor in the case of multi-story buildings, and are generally structural members used in buildings such as corners. It is also preferable to use core-connected laminated lumber in which many core members are stacked and crimped. As a specific example, it is also preferable to use BP material that is 600 mm x 600 mm in size, in which four square core members with a cross section of 150 mm x 150 mm are aligned vertically and horizontally and crimped.

[0023] The horizontal members 20 are members that are laid in the horizontal minor axis direction of the building and transmit the load of the floor, roof, etc. to the columns, and mainly bear bending stress with beams, girders, girder support, and foundations. The horizontal members 20 are rigidly connected to the vertical members 10 to form a rigid frame structure. There may be floors or stories that do not have floors or roofs and do not require the horizontal members 20 to transmit the load to the columns. As a specific example, it is also suitable to use BP material that is made by lining up five square core members with a cross section of 150 mm x 150 mm vertically and three horizontally and crimping them to 750 mm x 450 mm.

[0024] The mounting rod 30 has a threaded portion formed on the outer periphery of the reinforcing bar material, similar to a glued-in rod connection, and a high nut 60 is screwed onto one end, and is inserted into a rod insertion hole 40 provided in the cross 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 about 25 mm.

[0026] The adhesive 50 is used to insert the mounting rod 30, which has been inserted into the rod insertion hole 40, into the rod insertion holes 40 of the vertical member 10 and the cross member 20, and then treat it with a resin adhesive to fasten it to the surrounding wood.An epoxy-based resin adhesive or a polyurethane-based resin adhesive is used as the adhesive 50.

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

[0028] The connecting metal fitting 70 is a metal fitting for connecting the vertical member 10 and the horizontal member 20. As shown in Fig. 11, the connecting metal fitting 70 is composed of an abutment plate 100 that abuts against the contact surface 90 of the vertical member 10 and the horizontal member 20, and a frame body 110 that connects them, and the abutment plate 100 is provided with insertion holes 120 at predetermined positions for fastening with fixing bolts 80. The material may be general structural rolled steel that is often used at construction sites, but high tensile steel plate with a large specific strength is also suitable.

[0029] The fixing bolt 80 is a bolt that screws into the high nut 60 screwed into the end of the mounting rod, and this fixing bolt 80 is a screw-fitting member for firmly joining the vertical member 10 and the connecting member 70, or the cross member 20 and the connecting member 70, by clamping the abutment plate 100 of the connecting fitting 70 between the high nut 60 and the fixing bolt 80 and tightening it. In FIG. 8, a hexagonal bolt M20×75 mm full thread is shown as an example of the fixing bolt 80, but it may also be one with a distinctive bolt head such as a hexagonal socket bolt or a bolt with an assembled washer, or it may be a high tension bolt made of high tensile steel or stainless steel. In particular, the high tension bolt is made of high tensile steel (tensile strength of 490 N / mm 2 More than 1,000N / mm 2The bolt is manufactured from steel with less than 100% tensile strength, and is designed so that the axial force of the bolt (the tensile force acting in the axial direction of the bolt when it is 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 tensile nut 60.

[0030] The contact surface 90 is a surface that comes into contact with an abutment plate 100, which serves as the abutment surface of the joint fitting on the vertical member 10 and the horizontal member 20. It is also preferable to form a step surface on the vertical member 10 or the horizontal member 20 for positioning.

[0031] The abutment plate 100 constitutes the joint fitting 70, and is disposed so as to sandwich the frame body 110 between two plate-like bodies, with insertion holes 120 formed at predetermined positions.

[0032] As shown in FIG. 11, the frame 110 is sandwiched between two abutment plates 100 and firmly fixed by welding. In order to provide a predetermined length in the direction perpendicular to the load, for example, in the case of a joint metal fitting 70 in which the vertical members are 600 mm x 600 mm and the horizontal members are 450 mm x 750 mm, the length in the direction perpendicular to the load may be about 200 mm. In this case, the head length of the fixing bolt is 75 mm, taking into consideration the securing of space for inserting tools. The frame 110 is not limited to a lattice shape as shown in the cross-sectional views of the embodiments shown in FIG. 11(e) and FIG. 11(f). It may be a rectangular frame, a cylindrical frame, or a honeycomb shape.

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

[0034] Fig. 2 is an explanatory diagram of the joining state of a one-way rigid frame using the joining method and joint fittings of the vertical and horizontal members according to the present invention. The horizontal member 20 is rigidly joined to the vertical member 10 only in the X direction, and the right angles are maintained in other directions by braces or the like. Specifically, as shown in Fig. 2, rigid frames are assembled in a gate shape and arranged in a tunnel shape, with the rigid frame in the direction in which the horizontal member 20 is placed and braces are inserted in the depth direction to prevent the gate shape from collapsing. Since it is difficult to open the wall surface with braces, this is an example of a structural form suitable for factories, warehouses, gymnasiums, etc. Note that braces (diagonal braces), bearing walls, beams in the Y direction, etc. are omitted.

[0035] FIG. 3 is an explanatory diagram of the joining state of a two-way rigid frame using the joining method and joint metal fittings of the present invention for vertical members and horizontal members, and shows that the horizontal member 20 is rigidly joined to the vertical member 10 in both the X and Y directions. Specifically, as shown in FIG. 3, the major feature of the two-way wooden rigid frame construction method is that it enables rigid joining in two directions similar to that of a steel frame structure. Since wooden structures generally require braces and bearing walls, public facilities that require large openings and large spaces have mainly been made of steel frames or reinforced concrete structures. However, by using the joining method and joint metal fittings of the present invention for vertical members and horizontal members, the joint 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, and it is possible to support the load only with the vertical member 10 and the horizontal member 20 without the need for braces or bearing walls, which shows that it is possible to create a space with a sense of openness even in wooden structures.

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

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

[0038] The rod insertion hole drilling process A is a process A for drilling rod insertion holes 40 for inserting the mounting rods 30 into the ends of the vertical members 10 and the horizontal members 20, as shown in FIG. 5. For example, if the diameter of the mounting rod 30 is 20 mm, the hole is drilled so that the inner diameter is about 25 to 27 mm. The reason for drilling the hole diameter to be about 20% to 25% larger than the diameter of the rod is to improve the mounting property in the mounting rod mounting process B by fitting the rods together in a loose fit 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] The rod insertion hole drilling process A2 is a process for drilling rod insertion holes 40 for inserting the mounting rods 30 in two directions perpendicular to the horizontal direction of the vertical members 10 and at the ends of the cross members 20. The specific dimensions are the same as those of the rod insertion hole drilling process A.

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

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

[0042] The mounting rod installation process B is a process in which, as shown in FIG. 6, a mounting rod 30 with a high nut 60 screwed thereon is inserted into the rod insertion hole 40 drilled in the vertical member 10 and the horizontal member 20 by the rod insertion hole drilling process A, and, as shown in FIG. 7, adhesive 50 is pressed in from one end side of the mounting rod 30, filling it up to the other end side, and the mounting rod 30 is installed.

[0043] The mounting rod installation process B2 is a process in which a mounting rod 30 with a high nut 60 screwed into a rod insertion hole 40 drilled in two directions perpendicular to the horizontal direction of the vertical member 10 and at the end of the cross member 20 by the rod insertion hole drilling process A2, and then, as in the mounting rod installation process B, adhesive 50 is injected to install the mounting rod 30.

[0044] FIG. 8 is a process explanatory diagram illustrating a metal connector installation step C-C2 for installing a metal connector to one of a vertical member or a horizontal member according to the present invention.

[0045] As shown in Fig. 8, the connecting metal fitting installation process C is a process in which a connecting metal fitting 70 is attached to either the vertical member 10 or the horizontal member 20 with a fixing bolt 80 via a high nut 60 provided at one end of the mounting rod 30. Note that, although Fig. 8 illustrates an example in which the connecting metal fitting 70 is first joined to the vertical member 10, the connecting metal fitting 70 may be first joined to the horizontal member 20.

[0046] The connecting metal fitting installation process C2 is a process in which connecting metal fittings 70 are attached to two directions perpendicular to the horizontal direction of the vertical member 10 or to the horizontal member 20 with fixing bolts 80 via high nuts 60 provided on one end of the mounting rod 30. Note that while Fig. 8 illustrates an example in which the connecting metal fittings 70 are first joined to the vertical member 10, the connecting metal fittings 70 may be first joined to the horizontal member 20.

[0047] FIG. 9 is a process explanatory diagram illustrating steps D and D2 of joining a vertical member and a horizontal member, which connects a metal connector attached to a vertical member or a horizontal member to another vertical member or horizontal member according to the present invention.

[0048] Process D of joining the vertical member and the horizontal member is a process of fastening the high nut 60 provided at one end of the mounting rod 30 fixed to the other vertical member 10 or the horizontal member 20 to the connecting fitting 70 attached in process C of attaching the connecting fitting, using 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 provided at one end of the mounting rod 30 fixed to the other vertical member 10 or the horizontal member 20 to the joining fitting 70 attached in the joining fitting attachment process C2 with the fixing bolt 80.

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

[0051] Fig. 11 is an explanatory diagram of a joint metal fitting configuration explaining an embodiment of the basic shape of a joint metal fitting for connecting vertical members and horizontal members according to the present invention, in which Fig. 11(a) is a plan view, Fig. 11(b) is a left side view, Fig. 11(c) is a front view, Fig. 11(d) is a right side view, Fig. 11(e) is an e-e cross section, and Fig. 11(f) is an f-f cross section. Note that, in this embodiment, the frame body 110 connecting the two abutment plates 100 is shown in a lattice shape, but it is not limited to this lattice shape and may be a rectangular frame, a cylindrical frame, or a honeycomb shape. [Industrial Applicability]

[0052] The joining method and joining hardware for joining vertical and horizontal members of the present invention are suitable for medium to large facilities such as schools, hospitals, gymnasiums, libraries, and multi-story wooden houses. Since they are lighter than conventional reinforced concrete or concrete structures and contribute to the effective use of domestic timber, they are believed to have high industrial applicability.
