Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a scaffold wall connecting metal fitting for fixing a scaffold to a wall of a building to maintain buckling strength and stability of the scaffold.

[0002]

[Prior art]

 In conventional scaffolding wall tie fittings, a clamp provided at the base end is generally fixed to a rod member that constitutes a scaffolding such as a building or a building frame, while the length is adjusted by a step such as a turnbuckle. The scaffold is fixed to the wall by connecting the free end of the main part to the wall.

When the tip of the main portion is connected to the wall body, when the wall body is made of precast concrete, an anchor is embedded in the wall, and a screw portion at the tip of the main portion is screwed into this anchor. In the case of a panel wall that does not have such a thickness, generally, anchor bolts are attached to the structural frame, and the tip of the main part is connected to this by means of stay metal fittings.

Japanese Utility Model Publication No. 2-11551 discloses a wall connecting metal member for connecting a tip of a main part to a structural body without using an anchor bolt. The metal fittings are detachably attached to the tip of the main part so that they can be inserted into the gaps in the wall panels such as joints and the longitudinal gaps in the structural frame. At the tip of the insertion piece, a locking part that is thinner than the above-mentioned gaps and that is locked to the inner side surface of the structural body is formed. The part is locked to the structural body.

[0005]

[Problems to be solved by the device]

 However, with conventional wall joints that are connected to the structural frame, when the joint between the outer wall panels is filled with a sealing material such as caulking material, the joint between the anchor bolt and the tip of the main part or the insert itself penetrates into the joint. Because it does, it gets in the way.

[0006] Therefore, when the conventional metal fittings are used, the sealing work can be performed only after the wall panel is built and the wall connecting metal fittings are removed, and the safety of the scaffolding during the sealing work is increased accordingly. , Will be damaged. In addition, since the temporary contractor of scaffolding and the contractor of sealing work are usually different, if the sealing work is sandwiched between the removal of the wall tie and the dismantling work of the scaffolding, the overall efficiency of the outer wall construction will be poor. There is also a problem.

An object of the present invention is to seal joints while being connected to a structural frame, without sacrificing the safety of scaffolding during sealing work, and also for efficiently performing outer wall construction work. , To provide wall fittings for scaffolding.

[0008]

[Means for achieving the object]

 In order to achieve the above-mentioned object, the present invention is connected to a connecting member having one end fixed to a rod member which constitutes a scaffold, and is inserted into a joint of an outer wall panel, and is attached to a structural body of a building by a fastening member such as a screw. It consists of a block-shaped embedded metal fitting to be fixed, and a connection metal fitting that detachably connects this embedded metal fitting and the other end of the above-mentioned connecting metal fitting. While forming a screw hole in the embedded metal fitting, the tip of the connection metal fitting is formed. A threaded portion to be screwed into the above-mentioned screw hole of the embedded metal fitting, and a connection portion to which the other end of the connecting tool is detachably connected is provided on the head of the connection metal fitting. Among the intermediate parts from the screw part to the connection part of the metal fitting, at least the outer periphery of the part that penetrates into the joint is covered with a non-adhesive material such as fluororesin.

The embedded metal fitting may be configured such that the connection metal fitting covers the surface of the hollow with a non-adhesive material. In addition, a Teflon sleeve may be placed on the middle portion of the connection fitting.

[0010]

[Action]

 In this metal fitting, the connection metal fitting that connects the embedded metal fitting and the connector is covered with a non-adhesive material on the outer periphery of the part that penetrates into the joint, so the embedded metal fitting, the connection metal fitting, and the connector are connected. Even if the joint is filled with the sealing material as it is, the sealing material does not adhere to the middle part of the connecting fitting in the joint. Therefore, the connecting fitting can be easily removed from the embedded fitting by loosening the screw part at the tip after sealing the joint. Temporary scaffolding contractors can remove the wall fittings from the wall at the same time as dismantling the scaffold. If the surface of the connecting metal fitting of the embedded metal fitting is covered with a non-adhesive material, it is easy to remove and rotate the connecting metal fitting.

[0011]

【Example】

 Hereinafter, the present invention will be described in detail based on illustrated embodiments. FIG. 1 shows a wall connecting member according to an embodiment of the present invention.

In the figure, reference numeral 1 is a connecting member, which is similar to the above-mentioned main part of the known wall connecting metal fitting, and has the base end part 2 on the scaffold building 3 as shown in FIG. It is fixed to the handrail rod 4 via a clamp, and has a threaded portion 6 at the tip of a round bar.

Reference numeral 7 is a rectangular parallelepiped-shaped metal fitting that completely fits into a joint space 9 between adjacent outer wall panels 8 and 8. Through holes 7a and 7a for driving a drill screw are formed at both ends, and a connecting metal fitting is provided at a center portion. A screw hole 7b for connection with 10 is formed.

Reference numeral 10 denotes the connecting fitting, and a hexagonal head portion 11 is formed with a connecting screw hole 11a into which the screw portion 6 at the tip of the connecting tool is screwed, along the axial direction. A threaded portion 12 1 is provided at the tip of the connection fitting 10 1 so as to be screwed into the connection screw hole 7 b of the embedded fitting 7 and capable of being retracted. Further, the intermediate portion 13 between the head portion 11 and the connecting screw portion 12 of the connection fitting 10 is provided with a concavo-convex portion 13a in the outer peripheral axial direction thereof, and the sleeve 14 is covered so as to follow the concavo-convex portion 13a. Has been. The sleeve 14 is formed of a non-adhesive material such as Teflon, which is difficult for the sealing material 15 to adhere to. The sleeve 14 covers the outer periphery of the middle portion and then heat-treats it to bring it into close contact with the irregularities 13a. . This intermediate portion 13 of the connecting fitting 10 partially enters the joint space 9 when the embedded fitting 7 and the connecting tool 1 are connected to each other.

The surface of the metal fitting of the embedded metal fitting 7, that is, the surface of the metal fitting 10 into which the threaded portion 12 is screwed, is also covered with a similar Teflon sheet 16.

The usage state of this metal fitting will be described with reference to FIGS. 2 and 3. After the outer wall panel 8 is built, first, the embedded metal fitting 7 is inserted into the joint space 9 of the outer wall panel 8 to A drill screw 17 is driven into the through holes 7a, 7a to fix the embedded metal fitting 7 to the front of the structural steel material 18 behind the wall panel. Then, the threaded portion 12 of the connection fitting 10 is screwed into the connection screw hole 7b of the embedded fitting 7 to attach the connection fitting 10 to the embedded fitting 7, and then the threaded portion 6 of the connector 1 is connected to the connection fitting 10. The scaffold is connected to the wall by being screwed into the screw hole 7b.

Then, without removing the wall joint fitting from the structural body 18, a sealing company fills the joint material with the sealing material 15 under a stable scaffold.

After waiting for the sealing material 15 to dry, the scaffolding contractor removes the connector 1 from the connecting fitting 10 and the connecting fitting 10 from the embedded fitting 7. The connecting fitting 10 is in contact with the sealing material 15 at the middle and outer circumference of the joint (see FIG. 3), but since this contact portion is covered by the sleeve 14 made of non-adhesive material, the sealing material 15 Will not adhere. Further, since the Teflon sheet 16 is also attached to the outer surface of the embedded metal fitting 7, the connecting metal fitting 10 can be rotated and pulled out without difficulty when removing the connecting metal fitting 10 from the joint. Since the sleeve 14 is tightly covered with the unevenness 13a on the outer periphery of the middle portion of the connecting fitting, the sleeve 14 does not remain in the joint when it is removed.

After that, a sealing is filled in the hole after the connection fitting 10 is extracted, the surface is finished to be flat, and painting is performed. The above-described series of work is performed along with the dismantling work of the scaffold.

In addition, when connecting the connecting fitting and the connecting tool, in addition to this, the base end of the connecting fitting is made into a rod shape, and a male screw is formed on this, so that the threaded portion at the tip of the connecting tool and this male screw are connected to each other. The structure may be such that the length is adjustable by a turnbuckle.

[0020]

[Effect of device]

 As described above, according to the present invention, the embedded metal fitting fixed to the structural body and the other end of the connecting tool whose one end is fixed to the scaffold are detachably connected by the connection metal fitting. Since the outer periphery of the part that enters the joint is covered with a non-adhesive material, the joint can be filled with a sealing material while the structural body and scaffold are still connected, and the safety of the sealing work is maintained. In addition, the scaffolding temporary dismantling work and the sealing work can be efficiently performed.

Further, since the metal fittings can be arbitrarily connected at the joint position of the wall panel, the scaffolding can be fixed to the structural body at a desired position in consideration of the buckling strength of the scaffolding.
