Description

  The present invention relates to a mounting bracket for a diagonal reinforcing member, and more particularly to a mounting bracket for a diagonal reinforcing member for mounting a diagonal reinforcing member used in a ceiling foundation structure.

  A conventional ceiling base structure includes a field edge and a field edge receiver orthogonal to the field edge, and is supported by being suspended from a building structure with a suspension bolt (see, for example, Patent Document 1). .

  By the way, in the case of the ceiling foundation structure having the above configuration, the ceiling finishing board is attached to the field edge with a dedicated screw. On the ceiling, lighting fixtures and air conditioners are suspended from the building structure with suspension bolts, etc., and attached to the ceiling opening at the same height as the ceiling finish board surface. The workers are to inspect and repair lighting fixtures and air-conditioning equipment by looking through the ceiling through the ceiling inspection port, but there are many lighting fixtures on the ceiling, such as theaters, halls, gymnasiums, factories, etc.・ If there are air conditioners, etc., the ceiling will be high enough for people to walk, and a catwalk will be provided for inspection and repair. However, since the catwalk is not installed so as to cover all the ceiling surfaces, there are unavoidable cases where workers walk and inspect and repair conventional ceiling base materials. The conventional ceiling base material does not have a load-bearing structure that allows people to ride on the field edge, so a hanger fitting that connects the suspension bolt and the field edge or field edge receiver can be opened, There is a possibility that an accident occurs in which the edge of the rim falls and the ceiling surface becomes rattled, or in the worst case, the ceiling base material and the ceiling finishing board fall.

  Therefore, a suspended ceiling structure called a grape shelf in which pre-formed square steel is suspended from the building structure and arranged at regular intervals is adopted so that a plurality of people can ride. Even with such a suspended ceiling structure, there may be a problem with vibration resistance against severe shaking such as an earthquake.

  In order to cope with the above problems, as disclosed in Patent Document 1, the brace material is supported by being suspended from a building structure with suspension bolts, and the adjacent suspension bolts are oblique reinforcement members. It is considered that the vibration resistance is enhanced by connecting with (a brace-like member).

  In this case, the brace material is diagonally reinforced by firmly fixing the upper end side to the upper end portion of the suspension bolt and the lower end side to the base material for holding the ceiling plate material in the left and right directions and the front and rear direction of the ceiling. Therefore, the shaking in the respective directions of front, rear, left and right is surely suppressed.

  Conventionally, on-site welding has been performed as a method of fixing the upper end side of the brace material to the suspension bolt and the lower end side of the base material for holding the ceiling plate material. Due to individual differences, uniform strength cannot always be obtained, and it is necessary to perform on-site construction at a high place, so there are problems with safety as well as extra time and labor. .

  Therefore, in recent years, in order to achieve no welding, for example, an upper fixing bracket for fixing the upper end portion of the brace material has been adopted that includes a dedicated hanging bracket and a wing plate bolt. The top end of the brace material is fixed to the suspension bolt by screwing the one end side of the battledore bolt to this latching fitting and screwing the other end of the battledore bolt to the brace material with a tapping screw or the like. I am doing so.

  However, in the case of the upper fixing bracket having the above configuration, the hanging bracket is formed in advance so that the inclination angle between the suspension bolt and the brace material via the hanging bracket is always constant. This makes it difficult to reliably suppress the shaking of the ceiling, resulting in a new problem that it does not meet the seismic standards of the industry.

  As a countermeasure, for example, it is possible to change the mounting angle of the brace material to the base material for holding the ceiling plate material by changing the mounting angle of the wing plate bolt to the brace material. When the installation angle of the wing plate bolt is changed and fixed, the axial direction of the wing plate bolt and the extending direction of the brace material will not match, so if stress due to an earthquake or the like is applied to the brace material, the brace material will easily buckle. Become.

  Therefore, as an upper fixing bracket that fixes the upper end of the brace material, it swings between a clipper member that holds the suspension bolt by tightening the bolt and a coupling member that is fixed to the brace material via a pin or the like. There has also been proposed a structure in which the braces can be freely connected and the mounting angle of the brace material with respect to the base material for holding the ceiling plate can be arbitrarily adjusted.

  However, as described above, in the configuration in which the clipper member and the coupling member are swingably connected, there is an advantage that the angle of the brace material can be adjusted, but the clipper member is fixed to the suspension bolt. For this, an operation of fastening and fixing the clipper member with a bolt is required.

  Also, brace fixing to fix bracing for diagonal reinforcement that reinforces the connection between the suspension bolt suspended by the slab provided on the ceiling of the building and the base material for holding the ceiling plate material suspended from the suspension bolt. As an upper fixing metal fitting, a hook member that is hooked to hold the suspension bolt on the suspension bolt, a battledore bolt that has one end fixed to the brace, and a bolt formed on the other end of the battledore bolt There has already been proposed a configuration in which the hook member and the connecting member are connected to each other through a connecting pin so as to be swingable (see Patent Document 2). .

Japanese Patent Application Laid-Open No. 2008-050784. Utility model registration No. 315964.

  By the way, in the case of the upper fixing bracket disclosed in the above-mentioned Patent Document 2, the upper end of the brace material can be reliably and efficiently fixed to the suspension bolt without requiring any welding work, and the situation in the field is also improved. Although there is an advantage that the mounting angle of the brace material can be freely set within an appropriate range in accordance with the seismic standards of the industry, it can be hooked on the suspension bolt by turning the brace material for diagonal reinforcement However, if the lower end of the brace material for diagonal reinforcement is not in parallel with the rim support, the brace material for diagonal reinforcement and the rim receiver cannot be fixed with screws. In addition, if the lower end of the brace material for diagonal reinforcement is not parallel to the field edge holder, the hook member must be turned parallel to the direction of tightening the brace material for diagonal reinforcement so that it is parallel. There arises a problem that a slack is caused between the suspension bolt and the suspension bolt and the suspension bolt falls off.

  The present invention has been made in order to solve the above-described problems, and includes setting an attachment angle of an oblique reinforcing member (that is, an oblique reinforcing brace material) and hooking a hook member to a suspension bolt. It was made for the purpose of making it possible to perform a series of operations.

  In the present invention, as a first means for solving the above-described problems, a suspension bolt 2 suspended from a slab 1 provided on the ceiling side of a building, and a base for holding a ceiling plate material suspended from the suspension bolt 2 In the mounting member for the diagonal reinforcing member for fixing the upper portion of the diagonal reinforcing member 4 that connects and reinforces the material 3, it is hooked so as to hold the suspension bolt 2 at the upper end portion of the suspension bolt 2 and the inner surface A hook member 11 having a latching portion 11a formed with an internal screw 11b into which the suspension bolt 2 is screwed, a screw portion 12a having one end screwed into an appropriate position of the oblique reinforcing member 4, and the screw portion. An operation member 12 comprising an operation portion 12b on the other end side of 12a and having a pin or bolt 12c attached thereto, and can be moved up and down along the flat plate portion 11c of the hook member 11, and the operation is performed on the side surface. The link member 13 having a notch hole 13c through which a pin or bolt 12c of 12b is inserted and guided, and the operation member 12 is moved upward to set the inclination angle of the oblique reinforcing member 4 and the hook member. 11 is configured so that the suspension bolt 3 can be engaged with the suspension bolt 11 in an interlocking manner.

  With the configuration described above, the setting of the inclination angle of the oblique reinforcing member 4 and the hooking of the hook member 11 to the suspension bolt 2 can be performed in conjunction with each other by moving the operation member 12 upward. As a result, workability is significantly improved. In addition, since the internal thread 11b into which the suspension bolt 2 is screwed is formed in the above-mentioned latching portion, the hook member 11 will not accidentally fall off from the suspension bolt 2.

  In the present invention, as a second means for solving the above-mentioned problem, in the oblique reinforcing member mounting bracket provided with the above-mentioned first means, the linkage member is provided on the side of the hook member 11 on the side of the hooking portion. A circular projection 11e is formed to guide 13 when moving up and down.

  In such a configuration, the linkage member 13 is guided by the circular protrusion 11e and moves accurately, so that the inclination angle setting operation of the diagonal reinforcing member 4 and the suspension bolt 2 hooking on the hook member 11 are performed. The work can be performed more reliably.

  In the invention of the present application, as a third means for solving the above problems, in the diagonal reinforcing member mounting bracket provided with the first or second means, the upper end of the linking member 13 has an oblique reinforcing member. A horizontal portion 13e that is pressed against the lower surface of the slab 1 is integrally formed when the inclination angle 4 is set and when the suspension bolt 2 is hooked on the hook member 11.

  When configured in this manner, the horizontal portion 13e formed at the upper end of the linkage member 13 is pressed against the lower surface of the slab 1 when the inclination angle of the diagonal reinforcing member 4 is set and when the hook member 11 is hooked on the suspension bolt 2. As a result, it becomes difficult to sway against vertical and horizontal earthquakes, and the seismic performance is improved.

  According to the first means of the present invention, the gap between the suspension bolt 2 suspended from the slab 1 provided on the ceiling side of the building and the base material 3 for holding the ceiling plate material suspended from the suspension bolt 2 is provided. In the diagonal reinforcing member mounting bracket for fixing the upper portion of the diagonal reinforcing member 4 to be connected and reinforced, the suspension bolt 2 is hooked so as to hold the suspension bolt 2 at the upper end of the suspension bolt 2 and the suspension bolt 2 is screwed on the inner surface. A hook member 11 having a latching portion 11a formed with an internal screw 11b to be joined, a screw portion 12a whose one end is screwed into an appropriate position of the oblique reinforcing member 4, and the other end side of the screw portion 12a The operation member 12 includes an operation portion 12b to which a pin or bolt 12c is attached, and is movable up and down along the flat plate portion 11c of the hook member 11, and the pin or bolt of the operation portion 12b on the side surface. The link member 13 has a notch hole 13c for inserting and guiding 2c. By moving the operation member 12 upward, the inclination angle of the oblique reinforcing member 4 is set and the suspension to the hook member 11 is set. Since the engagement of the bolt 2 can be performed in conjunction with each other, the inclination angle of the oblique reinforcing member 4 and the suspension bolt 2 of the hook member 11 can be set by moving the operation member 12 upward. The hooking can be performed in conjunction with each other, and the workability is remarkably improved. In addition, since the internal thread 11b into which the suspension bolt 2 is screwed is formed in the hook portion 11a, there is an effect that the hook member 11 is not accidentally dropped from the suspension bolt 2.

  As in the second means of the present invention, in the diagonal reinforcing member mounting bracket provided with the first means, in the diagonal reinforcing member mounting bracket provided with the first means, the hook member 11 is counteracted. When the circular protrusion 11e that guides the linking member 13 when moving up and down is formed on the stop side, the linking member 13 is guided by the circular protrusion 11e and moves accurately. The angle setting operation and the hooking operation of the hook member 11 to the suspension bolt 2 can be more reliably performed.

  As in the third means of the present invention, in the mounting bracket for the oblique reinforcing member provided with the first or the second means, the upper end of the linkage member 13 is set at the inclination angle of the oblique reinforcing member 4 and the hook. When the horizontal portion 13e that is pressed against the surface of the slab 1 is integrally formed when the member 11 is hooked to the suspension bolt 2, the inclination angle of the oblique reinforcing member 4 and the hook member 11 to the suspension bolt 2 are set. At the time of latching, the horizontal portion 13e formed at the upper end of the linking member 13 is pressed against the lower surface of the slab 1, so that it is less likely to sway against vertical and horizontal earthquakes and the seismic performance is improved.

  As shown in FIG. 2, the diagonal reinforcing member mounting bracket T according to the present embodiment is hooked so as to hold the suspension bolt 2 at the upper end portion of the suspension bolt 2 and the suspension bolt 2 on the inner surface. A screw whose one end is screwed into an appropriate position of the hook member 11 having a latching portion 11a formed with an internal screw 11b (see FIG. 3) and a brace material 4 acting as the diagonal reinforcing member. An operation member 12 comprising a portion 12a and an operation portion 12b on the other end side of the screw portion 12a and having a pin or bolt 12c attached thereto, and vertically along the flat plate portion 11c (see FIG. 3) of the hook member 11 The linkage member 13 has a cutout hole 13a that is movable and has a side surface through which a pin or bolt 12c of the operation portion 12b is inserted and guided.

  As shown in FIG. 3, the hook member 11 is substantially entirely a flat plate portion 11c except for the latching portion 11a, and the flat plate portion 11c has a guide surface formed on an end surface of the linkage member 13. An angular protrusion 11d and a circular protrusion 11e that guide and guide 13b (see FIG. 5) when moving up and down are integrally provided. Reference numeral 11f is a pin hole or bolt hole through which one end of the pin or bolt 12c of the operation portion 12b in the operation member 12 is inserted.

  Further, as shown in FIG. 4, the operation member 12 is formed on two opposite sides of a U-shaped support member 14 (see FIG. 6) attached to an appropriate place (that is, the upper end portion) of the brace material 4. The screw portion 12a is inserted into the holes 14a, 14a, and the plate-like operation portion 12b is formed on the other end of the screw portion 12a and has a hole 12d through which the pin or bolt 12c is inserted. . Reference numeral 14b denotes a nut attached to one side edge of holes 14a and 14a formed on two opposite sides of the support member, and the screw portion 12a of the operation member 12 is screwed to the nut 14b. It is supposed to be done. Reference numeral 14 c denotes a screw hole through which a screw 14 d for fixing the support member 14 to the brace material 4 is inserted.

  Further, as shown in FIG. 5, the linking member 13 includes a pair of plate-like members 13b and 13b connected via a connecting portion 13a pressed against the outer periphery of the suspension bolt 2.

The setting of the inclination angle of the diagonal reinforcing member 4 and the hooking portion 11a of the hook member 11 to be hooked to the suspension bolt 2 can be performed in conjunction with each other, and the workability is remarkably improved. In addition, since the internal thread 11b into which the suspension bolt 2 is screwed is formed in the hooking portion 11a, the hook member 11 is not accidentally dropped from the suspension bolt 2. Moreover, since the circular protrusion 11e which guides the linkage member 13 at the time of the up-and-down movement is formed on the side of the hooking portion 11 in the hook member 11, the plate-like members 13b. The end face of 13b is guided by the angular protrusions 11d and the circular protrusions 11e of the hook member 11 and moves accurately, so that the setting operation of the inclination angle of the oblique reinforcing member 4 and the suspension bolt 2 to the hook member 11 are performed. Can be more reliably performed. That is, the rectangular protrusion 11d and the circular protrusion 11e complement the cutout hole 13c. Furthermore, a horizontal portion 13e that is pressed against the lower surface of the slab 1 is integrally formed at the upper end of the linkage member 13 when the inclination angle of the diagonal reinforcing member 4 is set and when the suspension bolt 2 is hooked on the hook member 11. Therefore, the horizontal portion 13e formed at the upper end of the linkage member 13 is pressed against the lower surface of the slab 1 when the inclination angle of the diagonal reinforcing member 4 is set and when the hook member 11 is hooked on the suspension bolt 2. Seismic performance is improved with less vibration against vertical and horizontal earthquakes.
