Description

  The present invention relates to a building wood connector for connecting a wooden building cross member and a wooden building vertical member erected on the upper or lower surface of the cross member.

  For example, there is an architectural timber connector used to connect wooden construction cross members such as foundations and beams and wooden construction vertical members such as pillars standing on the upper or lower surface of the cross members. Yes (Patent Document 1 etc.).

  This includes, for example, a metal fitting body formed by forming locking holes on both ends in the lengthwise direction of a rod-like body or a pipe-like body, and the above-mentioned inside of a hollow hole formed in a vertically and vertically communicating manner with a transverse member and a longitudinal member. A metal fitting body is inserted and disposed, and a fastening rod which is inserted through from the side of the cross member toward the boss hole is pierced and locked into the lock hole of the metal fitting body, and the boss is inserted from the side of the vertical member. By fixing the fastening rod inserted through the hole into the locking hole of the bracket body, the bracket body and the horizontal member are connected to each other, and the bracket body and the vertical member are connected to the pin by the fastening rod. Thus, the cross member and the vertical member are connected via the metal fitting body and the fastening rod.

  When the cross member and the vertical member are connected to a T-shape or a cross using such a construction wood connecting tool, the connecting portion is connected to the vertical member from the cross member due to an external force such as an earthquake or a wind. There may be a tensile force that pulls out the material. At that time, the fastening rod for pin-connecting the connection portion receives the resistance force of the wood fiber of the cross member or the vertical member and resists the external force.

  Therefore, considering the number of fastening rods that pin-connect the bracket body, cross member, and vertical member to obtain the required resistance (connection strength) according to the tensile force generated at the connection location, A metal fitting body that is appropriately designed to have a length dimension and the number of locking holes that pass through and lock the fastening rods is adopted and connected.

  By the way, when the strength of the timber itself of the cross member and the vertical member connected by using such a construction wood connector is not balanced, that is, for example, the vertical member (e.g. When the strength of the cross member is weak, when the tensile force pulls out the vertical member from the cross member is generated, the split material is split from the portion where the fastening rod of the weak member (cross member) is inserted. As a result, the desired resistance (connection strength) may not be exhibited.

  Therefore, the length of the metal fitting body is designed to be long and a large number of locking holes are formed in the metal fitting body designed to be long. By pin-connecting at a large number of locations, it is possible to prevent the splitting from occurring and make a strong connection.

  However, when the metal fitting main body is designed to be long in this way, there arises a problem that the metal fitting main body becomes bulky when the cross member or the vertical member is conveyed. That is, in recent years, this type of metal fitting body is often transported to the construction site after being attached to a horizontal or vertical member in advance at a factory other than the construction site. Therefore, as described above, the metal fitting body is elongated. When designed, the bracket body protrudes greatly from the side holes or vertical members of the horizontal and vertical members to which this bracket body is pre-installed, which becomes very obstructive when transporting wood (the load is bulky), and that much wasteful transportation This is costly and contributes to an increase in construction costs.

  The present invention is made in view of the current situation as described above, and provides an epoch-making and extremely practical construction connector that combines both high connection strength and excellent transportability. The task is to do.

  The gist of the present invention will be described with reference to the accompanying drawings.

The divided body 3A is composed of at least two divided bodies 3A, the divided body 3A inserted and arranged in the inside and the divided body 3A inserted and arranged in advance in the relief hole 2a of the longitudinal member 2. A joint locking hole 5A is formed at the end of one divided body 3A of 3A, and the joint locking hole 5A is communicated with the joint. When the locking hole 5B is formed in the other divided body 3A and the cross member 1 and the vertical member 2 are arranged at the connecting position, the end portion where the joint locking hole 5A of the one divided body 3A is formed. Is superposed on the other divided body 3A so that the joint locking holes 5A and 5B communicate with each other, and the cross member 1 or the longitudinal member is connected to the joint locking holes 5A and 5B connected to each other. The metal fittings so that the two divided bodies 3A can be connected and connected by passing through and locking a joint fastening rod 4A inserted through from the side of the material 2 toward the relief holes 1a and 2a. The present invention relates to an architectural wood connector characterized in that the main body 3 is configured.

  Further, an end of at least one of the two divided bodies 3A constituting the metal fitting body 3 is formed in a cylindrical shape, and an end of the other divided body 3A is formed in the cylindrical end. Is formed in a shape that can be inserted and disposed, and when the cross member 1 and the vertical member 2 are arranged at the coupling position, the other split member 3A is inserted into the cylindrical end portion of the one split member 3A. 2. The construction wood connector according to claim 1, wherein the metal fitting body 3 is configured such that the end portions are inserted and arranged so that the joint locking holes 5 </ b> A and 5 </ b> B communicate with each other. Is.

  Further, the two divided bodies 3A constituting the metal fitting main body 3 are formed of a rod-shaped member, and the diameter of one end of the one divided body 3A is larger than the end of the one divided body 3A. 3. The construction wood connector according to claim 2, wherein the end portion of the other small rod-like divided body 3A can be inserted and disposed.

  One split body 3A of the two split bodies 3A constituting the metal fitting main body 3 has a horizontal hole 1 or a vertical member 2 where the one split body 3A is inserted and disposed in advance. The length is set so that the end protrudes from the inside of 1a, 2a, and the joint locking hole 5A is formed in the protruding end, and the cross member 1 and the vertical member 2 are connected to each other. When arranged, the protruding end portion of the one divided body 3A protrudes from the side holes 1a, 2a of the cross member 1 or the vertical member 2 and into the side holes 2a, 1a of the vertical member 2 or the cross member 1 4.

The construction wood connector according to claim 4, wherein the length is set to be shorter than the depth dimension of the hollow holes 2a, 1a.

  Since the present invention is configured as described above, the metal fitting main body can be divided into at least two divided bodies. Therefore, after the metal fitting main body is attached to the cross member or the vertical member in advance in a factory other than the construction site. When transporting to a construction site, the metal fitting main body is divided, and the respective divided bodies can be transported in a state where they are inserted and disposed in the side holes and the vertical members.

  In other words, when a metal body designed to be long is inserted and placed in a horizontal hole or a vertical material, the long metal main body protrudes from the hole so that it is transported. Very disturbing. However, in this respect, the present invention can divide the metal fitting body, and one divided body can be inserted and disposed in the transverse hole of the horizontal member, and the other divided body can be inserted and disposed in the longitudinal hole of the longitudinal member, so that the wood can be conveyed. It is possible to transport the wood satisfactorily without projecting the metal fitting main body from the wood hole.

  That is, for example, if you want to connect firmly so that there is no splitting in the cross member or vertical member, the metal fitting body is designed to be long and have a number of locking holes, and use a number of fastening rods. Although it is desirable to connect the metal fitting main body to the cross member and the vertical member, until now, there has been a drawback that if the metal fitting main body is designed to be long, the transportability is significantly impaired. In this regard, according to the present invention, even if the metal fitting body is set to be long, the metal fitting main body does not get in the way when the wood is conveyed, and the conveyance performance is not significantly impaired.

  In addition, after the cross member and the vertical member are arranged at the connecting position, it is possible to easily connect the two pieces by simply passing through and engaging the joint fastening holes into the joint fastening holes of the two divided bodies which are connected to each other. The body parts can be joined together, and the metal fitting body is composed of a plurality of parts, so that the connection work becomes troublesome and does not require troublesome work.

Realizes a structure in which one split body and the other split body are partially overlapped with each other and the joint locking holes are connected to each other when they are placed at the connection position. In addition, the configuration of the present invention can be designed and realized more easily and reliably.

  In particular, in the invention according to claim 3, the two divided bodies can be simply constituted by a rod-like member, and the end of the other divided body is inserted into the end of one of the divided bodies. Can be easily and reliably realized, and the structure of the present invention can be easily designed and realized with a simple and simple structure, resulting in an architectural wood connector excellent in mass productivity and practicality.

  Further, in the invention according to claim 4, when the cross member and the vertical member are arranged at the connection position, the end portion where the joint locking hole of one divided body is formed is joined to the other divided body. The structure of the metal fitting main body of the present invention, which is superposed on the portion where the locking hole is formed, can be designed and realized more easily and reliably.

  Further, in the invention according to claim 5, when the metal fitting body is attached to the wood in advance, such as a cross member or a vertical material, and transported to the construction site, the length of the metal fitting body protruding in the vertical direction from the wood hole is set. Therefore, it is possible to reliably set the length shorter than that of the prior art, and therefore, it is possible to provide an excellent architectural wood coupler capable of exhibiting the excellent operational effects of the present invention more reliably.

  Embodiments of the present invention that are considered suitable (how to carry out the invention) will be briefly described with reference to the drawings, illustrating the operation of the present invention.

  When the wooden building cross member 1 and the wooden building vertical member 2 standing on the upper surface or the lower surface of the cross member 1 are connected to each other, the cross member 1 and the vertical member 2 are connected in the vertical direction. The metal fitting body 3 of the present invention is inserted and disposed in the tenon holes 1a and 2a, and the fastening rods 4 are inserted through the lateral members 1 and 2 from the sides toward the tenon holes 1a and 2a. The metal fitting body 3 and the cross member 1 and the vertical member 2 are connected (pin-connected) by the fastening rods 4 through the engagement holes 5 of the metal fitting body 3.

  Here, in the present invention, the metal body 3 is not formed of, for example, a single rod-like body or a pipe-like body as in the prior art, but when the transverse member 1 and the longitudinal member 2 are connected together, The divided body 3A is inserted into and disposed in the hole 1a, and the divided body 3A is inserted and disposed in advance in the side hole 2a of the longitudinal member 2. That is, the metal fitting body 3 of the present invention is configured to be divided into the two divided bodies 3A.

  The cross member 1 in which the one divided body 3A is inserted and disposed in advance in the side hole 1a and the vertical member 2 in which the other divided body 3A is inserted and disposed in advance in the side hole 2a are arranged at the connection positions. At this time, the end of one divided body 3A is superposed with the other divided body 3A, and the joint locking hole 5A formed at the end of the one divided body 3A and the joint formed at the other divided body 3A. The stop hole 5B is connected in a polymerized manner, and the joint stop is inserted through the joint locking holes 5a and 5B that are in polymerized communication with each other from the side of the cross member 1 or the vertical member 2 toward the side holes 1a and 2a. By joining and fixing the landing gear 4A, the two divided bodies 3A are joined and connected, thereby connecting the cross member 1 and the vertical member 2 together.

  Therefore, for example, in a factory other than the construction site, one divided body 3A is connected in advance to the side holes 1a of the cross member 1 by the fastening rods 4, and the other divided body 3A is connected to the side holes 2a of the vertical member 2. If connected by the fastening rod 4, at the construction site, the cross member 1 and the longitudinal member 2 are arranged at the coupling position and joined to the joint locking holes 5A and 5B of the respective divided bodies 3A. The cross member 1 and the vertical member 2 can be connected very quickly and easily by only the operation of penetrating and locking 4A.

  For example, the metal fitting body 3 is designed to have a longer overall length and a larger number of locking holes 5 are formed, and accordingly, the horizontal holes 1 and the vertical holes 2 are formed longer (deeper). However, if the metal fitting body 3 is connected to the cross member 1 and the vertical member 2 by using a larger number of fastening rods 4 (pin connection), the metal fitting body 3, the cross member 1, the vertical member 2 and Can be firmly connected to each other, and it is possible to satisfactorily prevent the transverse member 1 and the longitudinal member 2 from being split.

  However, if the metal fitting body 3 is designed to be longer in this way, the metal fitting body 3 can be used as a tenon hole in wood when the metal fitting body 3 is attached to the cross member 1 or the vertical member 2 in advance and then transported to the construction site. There are disadvantages such as a large (long) protrusion from the inside of 1a and 2a that obstructs the conveyance, the load is very bulky, and consequently the conveyance efficiency is impaired and an extra conveyance cost is required.

  However, in this respect, in the present invention, the metal fitting body 3 can be divided into two divided bodies 3A, and each divided body 3A is inserted and disposed in the side hole 1a of the cross member 1 or the side hole 2a of the vertical member 2, respectively. Therefore, even if the overall length of the metal fitting body 3 is designed to be long, the length that each divided body 3A protrudes from the inner holes 1a and 2a of the cross member 1 and the vertical member 2 is shortened. As long as it is set, the metal fitting body 3 can be designed to have a sufficiently long dimension without sacrificing the transportability.

  Accordingly, the cross member 1 and the vertical member 2 can be quickly and easily connected to each other at the construction site, and the workability is excellent. Depending on the design, the cross member 1 may be formed using a long metal fitting body 3 and a number of fastening rods 4. It is an epoch-making architectural wood coupler that exhibits extremely high practical value for this kind of building wood connection, such as being capable of firmly connecting the vertical member 2 and the vertical member 2 and having excellent transportability.

  A first embodiment of the present invention will be described with reference to the drawings.

  The present embodiment is an architectural wood connector for connecting a wooden building cross member 1 and a wooden building vertical member 2 standing on the upper surface or the lower surface of the cross member 1. And a metal fitting body 3 that is inserted into the vertical holes 2 so as to communicate with the vertical member 2 in the vertical direction. The metal fitting body 3 is formed from the side of the cross member 1 and the vertical member 2 from the side. A plurality of locking holes 5 for penetrating and locking the fastening rods 4 penetratingly inserted toward each of the relief holes 1a and 2a are formed, and the cross member 1 is preliminarily connected when the cross member 1 and the vertical member 2 are connected. The divided body 3A inserted and disposed in one ridge hole 1a and the divided body 3A previously inserted and disposed in the horn hole 2a of the longitudinal member 2 are configured to include at least two divided bodies 3A, A joint locking hole 5A is formed at the end of one split body 3A of the two split bodies 3A, and this joint locking hole 5A is polymerized. The joint locking hole 5B to be passed is formed in the other divided body 3A, and when the cross member 1 and the vertical member 2 are arranged at the connecting position, the joint locking hole 5A of the one divided body 3A is formed. The formed end portion overlaps with the other divided body 3A so that the joint locking holes 5A and 5B communicate with each other and are connected to the joint locking holes 5A and 5B connected to each other. The two split bodies 3A can be joined and connected by penetrating and engaging a joint fastening rod 4A that is inserted through from the side of the material 1 or the longitudinal member 2 toward the relief holes 1a and 2a. Thus, the metal fitting body 3 is configured as described above.

  Hereinafter, the present embodiment will be specifically described.

  In the present embodiment, as illustrated in FIGS. 1 to 5, a case where the vertical member 2 is connected to the lower surface of the cross member 1 in a T shape will be described as an example.

  As shown in FIGS. 1 and 4, the cross member 1 is formed with a side hole 1a in a vertically penetrating state, and a stop for inserting the fastening rod 4 through the cross member 1 from the side. The hole 6 is formed so as to penetrate in a substantially horizontal direction from one side surface of the cross member 1 through the relief hole 1a to the other side surface. In the present embodiment, the fastening holes 6 are formed through three positions at the top and bottom of the cross member 1.

  Further, the upper end of the transverse hole 1a of the cross member 1 is formed to have a large diameter, and a fitting engagement hole 8 is provided in which a latching jaw portion 7 of an upper end portion of the metal fitting body 3 to be described later is fitted and abutted and locked. It has a configuration.

  On the other hand, as shown in FIGS. 1 and 4, the vertical member 2 is provided with a horizontal hole 2 a communicating vertically with the horizontal hole 1 a of the horizontal member 1 from the upper end portion downward. A fastening hole 6 for penetrating and inserting the fastening rod 4 from the side of the material 2 is formed so as to penetrate in a substantially horizontal direction from one side surface of the vertical member 2 through the side hole 2a to the other side surface. Yes. In the present embodiment, the fastening holes 6 are formed in two horizontal directions perpendicular to each other at two positions on the vertical member 2.

  As shown in FIG. 1, the metal fitting body 3 includes a divided body 3 </ b> A that is inserted into the side holes 1 a of the cross member 1 and a divided body 3 </ b> A that is inserted into the side holes 2 a of the vertical member 2. The body is composed of divided body 3A.

  In addition, when the cross member 1 and the vertical member 2 are arranged at the connection position, the portion where the joint locking holes 5A and 5B of the two split bodies 3A are formed is superposed, for example, The end sides of the divided body 3A that are superposed on each other are formed in a plate shape, and the cross member 1 and the vertical member 2 are arranged at the connection positions so that the plate end portions of the split members 1A are in the side holes 1a of the cross member 1. Alternatively, various configurations such as plate superposition of the vertical members 2 in the side holes 2a can be adopted. However, in the illustrated embodiment, the end of one divided body 3A is formed in a cylindrical shape, and this cylindrical end is formed in the cylindrical end. By inserting and arranging the end of the other divided body 3A, the portions where the joint locking holes 5A and 5B of the two divided bodies 3A are formed are superposed.

  Specifically, as shown in FIG. 1, the two divided bodies 3A are each constituted by a rod-like member, and the other divided body 3A is configured to have a smaller diameter than the one divided body 3A. And it is comprised so that the edge part of the other division body 3A can be inserted and arrange | positioned at the edge part of this division body 3A.

  In this embodiment, the divided body 3A inserted and disposed in the side hole 1a of the transverse member 1 is configured to have a smaller diameter than the divided body 3A inserted and disposed in the side hole 2a of the longitudinal member 2. The split member 3A on the side of the transverse member 1 having a small diameter is set to a length shape in which an end protrudes from the inside of the relief hole 1a when inserted into the relief hole 1a of the transverse member 1. The joint locking hole 5A is formed at the end. Specifically, as shown in FIGS. 2, 4, and 5, the upper end portion of the divided body 3 </ b> A on the cross member 1 side is provided with a locking jaw portion 7 that horizontally protrudes in a flange shape. A split body 3A on the material 1 side is inserted and disposed from above into a side hole 1a formed in the cross member 1, and the locking jaw 7 is inserted into the insertion locking hole 8 at the upper end of the side hole 1a. Thus, the lower end of the split member 3A on the side member 1 side is formed so as to protrude downward from the side hole 1a of the side member 1 when being brought into contact with and locked.

  Then, when the cross member 1 and the vertical member 2 are arranged at the connection positions, as shown in FIGS. 4 and 5, the end portion in which the joint locking hole 5A of the split member 3A on the cross member 1 side is formed. Protrudes from the side holes 1a of the cross member 1 into the side holes 2a of the vertical member 2, and from the end of the divided body 3A in the side holes 2a of the vertical member 2, the divided body 3A on the vertical member 2 side. The length is set so as to be inserted into the inside.

  4 and 5, the two split members 3A are inserted and fitted into each other, so that the joint locking holes 5A and 5B are overlapped and communicated with each other. The protruding length of the end of the body 3A and the formation positions of the joint locking holes 5A and 5B of each divided body 3A are set.

  However, the protruding length at which the protruding end portion forming the joint locking hole 5A of the split member 3A on the side member 1 side protrudes from the side hole 1a of the side member 1 is such that the side member 1 and the vertical member 2 are mutually connected. When arranged at the connecting position, the protruding end portion is set so as to have a protruding length that does not reach the bottom portion of the longitudinal hole 2a of the longitudinal member 2 (which is shorter than the depth dimension of the longitudinal hole 2a of the longitudinal member 2) (see FIG. 4, 5).

  That is, when the cross member 1 and the vertical member 2 are arranged at the connection position, the joint locking hole 5A formed in the protruding end portion of the split member 3A on the cross member 1 side is divided into the split member on the vertical member 2 side. If it has a projecting length that reaches the polymerization communication position with the joining hole 5B formed in 3A and the fastening hole 6 formed in the position closest to the upper end (close to the cross member 1) of the vertical member 2 Since it is not necessary to project longer than that, it is possible to easily design a length that the metal fitting body 3 projects from the wood at the time of conveyance as compared with the conventional case.

  The split member 3A on the cross member 1 side communicates with the fastening hole 6 of the cross member 1 above the joint locking hole 5A in addition to the joint locking hole 5A at the end. Locking holes 5 are formed in three upper and lower portions, respectively. Each of the locking holes 5 and the joint locking holes 5A is formed by penetrating in a horizontal direction in a rod-like member constituting the divided member 3A on the side member 1 side.

  In addition, the split member 3A on the vertical member 2 side is at least below the joint locking hole 5B that is in communication with the joint locking hole 5A of the split member 3A of the cross member 1 (the bottom of the relief hole 2a). The locking hole 5 is formed at one or more locations on the side. In the present embodiment, when the divided body 3A is inserted and disposed in the relief hole 2a of the longitudinal member 2, the fastening hole 6 formed at a position closest to the upper end of the longitudinal member 2 (close to the opening of the relief hole 2a). The joint locking hole 5B is formed at a location communicating with the locking hole 5, and the locking hole 5 is formed at a location communicating with the fastening hole 6 formed below the fastening hole 6 near the upper end. Each of the locking holes 5 and the joint locking holes 5B is formed by penetrating in a horizontal direction in a rod-like member constituting the split member 3A on the longitudinal member 2 side.

  Accordingly, the fastening rod 4 inserted through the fastening hole 6 formed at the position closest to the upper end of the longitudinal member 2 not only connects the longitudinal member 2 and the split member 3A on the longitudinal member 2 side by pins, As shown in FIGS. 4 and 5, the two members are penetrated and locked into the joint locking hole 5A of the split member 3A on the cross member 1 side and the joint locking hole 5B of the split member 3A on the vertical member 2 side. It is the structure which also serves as the said joining stop rod 4A which joins and joins the divided body 3A.

  In addition, as shown in FIGS. 2, 4 and 5, the end of the split member 3A on the vertical member 2 side is also set to a length that slightly protrudes from the inside of the relief hole 2a of the vertical member 2. Yes.

  As shown in FIGS. 4 and 5, the transverse hole 1a of the cross member 1 is a fool hole set larger than the cylindrical diameter of the split member 3A on the cross member 1 side, and the split member 3A on the vertical member 2 side. The end portion of the vertical member 2 protrudes slightly from the side hole 2a of the vertical member 2 and is inserted into the side hole 1a of the horizontal member 1 so as to be fitted to the side hole 1a. is doing.

  Therefore, when the cross member 1 and the vertical member 2 are arranged at the connection position, the end of the split member 3A on the vertical member 2 side slightly protrudes and fits into the side hole 1a of the cross member 1. The horizontal member 1 and the vertical member 2 are positioned in the horizontal direction, and the horizontal member 1 and the vertical member 2 can be connected more firmly and without backlash in the horizontal direction.

  Only the divided member 3A on the cross member 1 side may project from the inside of the relief hole 1a. However, as in this embodiment, the divided member 3A on the longitudinal member 2 side also protrudes from the inside of the relief hole 2a, and the protruding end portion thereof. Can be fitted to the side hole 1a of the horizontal member 1a so that the horizontal strength between the horizontal member 1 and the vertical member 2 can be eliminated and the connection strength can be improved. For example, the overall length of the metal fitting 3 is slightly increased. Depending on the design, it is possible to design it to be short and to have sufficient connection strength while reducing the number of locking holes 5.

  In addition, as for the rod-shaped member which comprises the two division bodies 3A of this metal fitting main body 3, it is desirable to employ | adopt a member (metal material etc.) with high durability strength.

  In this embodiment, a rod-shaped member having a small diameter is used for the divided body 3A on the side of the cross member 1, and a rod-shaped member having a large diameter is used for the divided body 3A on the side of the vertical member 2. In addition to this, the metal fitting body 3 of the present embodiment is not limited to the above-described configuration, and may be designed in any shape as long as it exhibits the same function as the present embodiment.
