Description

  The present invention relates to a slope-corresponding brace joint hardware for joining a brace applied to a sloped part such as an inclined wall or a sloped ceiling to a building frame, and a building frame structure using the same.

In order to give the building rigidity, it is common practice to use fire and plywood for horizontal construction and braces and plywood for vertical construction.
However, in the case of an inclined ceiling or an inclined wall for satisfying the inclination restriction, the brace has an inclination in two directions, an in-plane direction and an out-of-plane direction. Therefore, it is difficult to construct by the above general construction method. Therefore, in the case of sloped ceilings and sloped walls, hardware is individually designed for each slope.
Patent Document 1 describes a field plate corresponding to an inclined wall.

JP 2011-220072 A

When a brace is attached to a sloped roof or an inclined wall, it is necessary to incline in two directions, the in-plane direction and the out-of-plane direction as described above. If it is only in the in-plane direction, it can be handled by a normal brace joint structure. However, the inclination in the out-of-plane direction can only be dealt with by a metal shape. Therefore, it is necessary to manufacture hardware individually in order to obtain a shape that matches the gradient depending on the shape of the building and the location of use. As a result, the hardware design takes time, and the price of the hardware tends to increase due to the high-mix low-volume production.
Also in the above-mentioned Patent Document 1, there is no description or suggestion about hardware corresponding to various gradients in the out-of-plane direction.

  An object of the present invention is used for joining braces of sloped surfaces such as sloped roofs and sloped walls, and can change the slope in the out-of-plane direction freely, and has a simple structure and supports a slope-compatible brace joint. And it is providing the building frame structure using this.

  The gradient-corresponding brace joint hardware of the present invention includes a screw rod having a male screw portion, a nut portion screwed into the male screw portion of the screw rod, and a joint piece portion for joining the braces of the building frame integrated with the nut portion. A movable brace joint member, and a housing mounting member that supports the end of the screw rod and fixes the screw rod to the building housing. The brace may be made of steel or wooden.

According to this configuration, the movable brace joining member can freely rotate around the screw rod at the nut portion. Therefore, the brace can be freely inclined in the out-of-plane direction. Moreover, since the movable brace joining member is screwed to the screw rod by the nut portion, it does not move unexpectedly in the longitudinal direction of the screw rod. Therefore, it is not necessary for the means for positioning the movable brace joining member in the longitudinal direction of the screw rod, and the structure becomes simple.
In this way, when used for joining braces of sloped surfaces such as sloped roofs and sloped walls, the slope in the out-of-plane direction can be freely changed and a simple configuration is obtained.

In the gradient-corresponding brace joint hardware according to the present invention, the housing mounting member may be composed of two L-shaped plate portions, and both ends of the screw rod are joined to each plate portion.
In the case of this configuration, the two plate portions of the housing attachment member can be attached to these beams and columns at, for example, a joint between the beam and the column of a building. Also, since both ends of the screw rod are joined to two L-shaped plate portions, the movable brace joining member does not interfere with these two plate portions, and other components for avoiding interference are provided. It is not necessary to provide it.

In this invention, the said housing attachment member may be a flat plate shape, and the said screw rod may be the shape bent so that both ends may be joined to the said housing attachment member and the intermediate part may float from the said housing attachment member.
In the case of this configuration, since the frame mounting member is flat, the frame mounting member is not limited to the corner portion between the column and the beam, and the frame mounting member can be installed at an arbitrary position of the beam or column.

Further, in the present invention, there are two housing attachment members, and both ends of the screw rod are fixed to each other, and the two housing attachment members are separated from each other at least by a distance that does not interfere with the movable brace joining member. It is good also as a structure.
In the case of this configuration, since there are two housing mounting members, it is necessary to perform separate mounting work. However, the movable brace joint member interferes with the housing mounting member without specially modifying the shape of the screw rod or the housing mounting member. Can be avoided.

The gradient-corresponding brace joint hardware of any one of the above configurations of the present invention may be configured to have a locking nut that is screwed onto the screw rod on both sides of the nut portion and presses the end surface of the nut portion.
In the case of this configuration, it is possible to prevent the movable brace joining member from rotating by tightening the locking nut after the brace construction is completed. Therefore, for example, when the brace is a member having a function of applying a compressive force, it is avoided that the movable brace joining member rotates and obstructs the transmission of the compressive force. In addition, when a tensile force acts on the brace, there is no problem even if the gradient-corresponding brace joint hardware rotates.

  Since the building frame structure of the present invention includes the gradient-corresponding brace joint hardware of any one of the above-described configurations of the present invention, a common slope-corresponding brace joint hardware can be used even if the slopes are variously different. It is not necessary to use brace connection hardware and can be manufactured at low cost.

  The gradient-corresponding brace joint hardware of the present invention includes a screw rod having a male screw portion, a nut portion screwed into the male screw portion of the screw rod, and a joint piece portion for joining the braces of the building frame integrated with the nut portion. Is used for joining braces on surfaces with slopes, such as sloped roofs and sloped walls. The gradient in the out-of-plane direction can be freely changed, and can be manufactured inexpensively with a simple configuration.

  Since the building frame structure of this invention is provided with the gradient-corresponding brace joint hardware of any one of the above-described configurations of the present invention, a common slope-corresponding brace joint hardware can be used even if the slopes are variously different, and according to individual design. It is not necessary to use brace connection hardware and can be manufactured at low cost.

  A gradient-corresponding brace joint hardware according to a first embodiment of the present invention will be described with reference to FIGS. The gradient-corresponding brace joint hardware 1 includes a screw rod 2 having a male screw portion 2e, a nut portion 3 screwed into the male screw portion 2e of the screw rod 2, and a brace (muscle of the building frame integrated with the nut portion 3). A movable brace joining member 5 having a joining piece portion 4 for joining 8) and a housing attaching member 6 that supports the end portion of the screw rod 2 and is fixed to a building housing.

  In this example, the screw rod 2 is a full screw bolt in which a male screw portion 2e is formed over the entire length. However, the male screw portion 2e is in a range where the nut portion 3 of the screw rod 2 is screwed, for example, only near the center. It is also good. In that case, for example, it is preferable that the male screw portion 2 e has a larger diameter than other portions so that the nut portion 3 can be screwed into the male screw portion 2 e from one end of the screw rod 2.

  The housing mounting member 6 is composed of two L-shaped plate portions 6a and 6b, and both ends of the screw rod 5 are joined to the plate portions 6a and 6b by welding or the like. The plate portions 6a and 6b are provided with a plurality of attachment holes (not shown) through which bolts and screws for attachment to the housing are inserted.

  The nut part 3 in the movable brace joining member 5 is a long nut, and the joining piece part 4 is a rectangular steel plate or the like, and is joined to the nut part 3 by welding or the like. The nut portion 3 and the joining piece portion 4 may be processed from one member. The joint piece 4 has a bolt hole 7 as an attachment hole, and a connection metal 9 at the end of the brace 8 is overlapped on the joint member 5, and the bolt hole 10 and the bolt hole 7 of the connection metal 9 are overlapped. The bolts and nuts (both not shown) inserted through the bolts are tightened and joined. The brace 8 is formed by joining the connection hardware 9 to both ends of a shaft member 8a such as a steel rod, and may have a turnbuckle (not shown) in the middle of the shaft member 8a.

  In the gradient-corresponding brace joint 1, for example, the frame attachment member 6 is fixed to the beam 21 and the column 22 of the building frame by the two plate portions 6 a and 6 b. The brace 8 is joined to the gradient-corresponding brace joint hardware 1.

According to the gradient-corresponding brace joint hardware 1 having this configuration, the movable brace joint member 5 can freely rotate around the screw rod 2 by the nut portion 3. Therefore, the brace 8 can be freely inclined in the out-of-plane direction. Further, since the movable brace joining member 5 is screwed to the screw rod 2 by the nut portion 3, the movable brace joining member 5 does not move unexpectedly in the longitudinal direction of the screw rod 2. A means for positioning in the direction is not necessary and has a simple configuration.
For this reason, this gradient-corresponding brace joint hardware 1 can freely change the gradient in the out-of-plane direction when it is used for joining braces having a slope such as a sloped roof or an inclined wall. And it becomes a simple structure.

  In addition, since the housing attachment member 6 is formed in an L shape, the two plate portions 6a and 6b are joined to the beam 21 and the column 22 at the joint portion between the beam 21 and the column 22 as described above. Can be installed. Further, since both ends of the screw rod 2 are joined to the two plate portions 6a and 6b having an L shape, the movable brace joining member 5 does not interfere with the two plate portions 6a and 6b. It is not necessary to provide other components for avoidance.

In the example of FIG. 1, the nut portion 3 of the movable brace joining member 5 is not particularly restricted. However, as shown in FIG. 2, the screw rod 2 is screwed on both sides of the nut portion 3 to A lock nut 11 that presses the end surface of the nut portion 3 may be provided. The lock nut 11 is, for example, a normal hexagon nut.
In the case of this configuration, after the construction of the brace 8 is completed, by tightening the locking nut 11, there is no play in the thread groove (not shown), it is firmly fixed, and the movable brace joining member 5 rotates. Can be prevented. Therefore, for example, when the brace 8 is a member having a function of applying a compressive force, it is avoided that the movable brace joining member 5 rotates and obstructs the transmission of the compressive force. In addition, when a tensile force acts on the brace, there is no problem even if the gradient-corresponding brace joint hardware rotates.

  FIG. 3 shows another embodiment. Other than the matters to be specifically described, the second embodiment is the same as the first embodiment shown in FIGS. In the gradient-corresponding brace joint 1A according to this embodiment, the housing mounting member 6 has a flat plate shape, the screw rod 2 is joined to the housing mounting member 6 at both ends, and an intermediate portion is lifted from the housing mounting member 6. It is made into the shape bent by. Specifically, the screw rod 2 is positioned between the linearly raised portion 2a at the center, the linear fixed portion 2b joined to the housing mounting member 6 by welding, and between the raised portion 2a and the fixed portion 2b. And an inclined portion 2c.

  In the case of this configuration, since the frame mounting member 6 is flat, the frame mounting member 6 is not limited to the corner portion where the column and the beam are joined, and the frame mounting member 6 is an arbitrary beam 22 or column (not shown in FIG. 3). Can be installed in position.

4 and 5 show an example of a building frame structure in which the gradient-corresponding brace joint hardware 1 and 1A are installed on an inclined wall 31 which is a part of the outer wall of the building. The inclined wall 31 is configured by stretching an exterior surface material (not shown) on an inclined bar 28 installed on the lower and upper beams 23 and 24. The upper beam 24 is in a position retracted from the lower beam 23 and is joined to the upper end of a column 26 built on the lower beam 25. A beam 27 extending to the indoor side is joined to the beam 24.
In FIG. 5, the gradient-corresponding brace joint hardware 1 and 1A are shown in a simplified manner.

  In the example shown in the figure, the slope-corresponding brace joint hardware 1 according to the embodiment shown in FIG. 1 is installed at the corner formed by the upper beam 24 and the column 26 in an upside down orientation from that shown in FIG. Further, a gradient-corresponding brace joint 1A according to the embodiment of FIG. 3 is installed upward on the upper surface of the lower beam 23. Both ends of the brace 8 are joined to the upper and lower gradient-corresponding brace joint hardwares 1 and 1A.

  As described above, by installing the gradient-corresponding brace joint hardware 1, 1 </ b> A according to the above-described embodiment on the inclined wall 31, the movable brace joint member 5 freely rotates, so that it corresponds to an arbitrary gradient of the inclined wall 31. Thus, the brace 8 can be installed.

6 and 7 show a building frame structure using the slope-corresponding brace joint hardware 1 and 1A according to the embodiment of FIG. 1 or FIG. 3 as the slope ceiling. As shown in FIG. 6, beams 41, 42, and 43 are installed in the eave portion, the ridge portion, and the middle thereof, and the roof surface material 46 is stretched thereon. An inclined beam 45 is provided orthogonal to the beams 41, 42, 43 as shown in FIG. 7, and a brace 8 is stretched at a location surrounded by these beams 41, 42, 43, 45. The both ends of the brace 8 use the gradient-corresponding brace joint hardware 1 and 1A according to the embodiment of FIG. 1 or FIG. When the slope-corresponding brace joint hardware 1 of FIG. 1 is used, the slope-corresponding brace joint hardware 1 is connected to the horizontal beams 41, 42, 43 located in the eaves, the ridge or the middle, and the inclined beam 45. The plate portions 6a and 6b are attached. When using the gradient-corresponding brace joint 1A of FIG. 3, it is attached to the beams 41, 42, 43 in the horizontal direction, for example.
In this way, by installing the gradient-corresponding brace joint hardware 1, 1 </ b> A, the movable brace joint member 5 freely rotates, so that the brace 8 can be installed corresponding to an arbitrary slope of the ceiling surface. Can do.

8 to 10 show gradient-corresponding brace joint hardware 1B, 1C, and 1D, respectively, according to still another embodiment of the present invention. These embodiments are examples where the brace 8 is wooden. The brace 8 is specifically a flat rectangular member.
In the embodiment of FIG. 8, a plurality of fixing tool insertion holes 7 </ b> A for joining a wooden brace 8 are provided in the joining piece 4 of the movable brace joining member 5 in the embodiment of FIG. 1. A fixing tool such as a wood screw or a nail is used for the fixing tool insertion hole 7A.

  In the embodiment of FIG. 9, a plurality of fixing tool insertion holes 7A for joining wooden braces 8 are provided in the joining piece portion 4 of the movable brace joining member 5 in the embodiment of FIG.

  In the example of FIG. 10, the housing attachment member 6 includes two divided housing attachment members 6 c and 6 c, and both ends of the screw rod 2 are fixed to the respective divided housing attachment members 6 c and 6 c. The two split housing attaching members 6c, 6c are separated from each other by a distance at which the movable brace joining member 5 does not interfere. In this configuration, a plurality of fixing tool insertion holes 7 </ b> A for joining wooden braces 8 are provided in the joining piece portion 4 of the movable brace joining member 5.

As shown in FIGS. 8 to 10, even if the brace 8 is made of wood, the gradient-corresponding brace joint hardware 1 to 1D can be applied.
In that case, a simple method of constructing wood screws or nails can be adopted in advance, and the cost is very low and cost-effective. The fixing or reinforcing wood screws and nails are more effective than a single one, and the number and arrangement of the fixing tool insertion holes 7A may be appropriately designed according to the required performance. The reinforcing wood screw and nail need not have a special shape, and may be a general wood screw (such as a corus thread) or a nail (such as a CN nail), and a sufficient fixing effect can be obtained. Although it is important that the wood brace 8 is constructed so that there are no steps in the screw heads and nail heads of the wood screws, it is easy to manage the construction and to ensure stable performance. The longer and thicker the wood screws and nails for reinforcement, the higher the reinforcement effect. Moreover, in order to make a wood screw and a nail | claw work effectively, it is good to construct in the place where it sinks most.

  10 can be applied to the steel brace 8 by reducing the number of the fixing tool insertion holes 7A, for example, the number of the fixing tool insertion holes 7A is one. Become. In the case of the embodiment of FIG. 10, since there are two housing attachment members, it is necessary to attach them separately. However, the movable brace joint member 5 is not particularly required for the shape of the screw rod 2 or the housing attachment member 6. Is prevented from interfering with the housing attachment member 6.
