Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wall tie support reinforcement for reinforcing a wall tie support used for connecting a scaffold assembled to the outside of a building to a building frame with a wall tie material.

[0002]

2. Description of the Related Art Conventionally, when a scaffold is built around a building such as a house, for example, a wall connecting material that is joined to the outer wall of the building is generally used for preventing collapse and stability. The wall connecting material joins the tip of the wall connecting material on the building side, but the wall connecting material generally tends to be weak against compressive force and bending force even though it is strong against tensile force. In particular, in a building in which the outer wall is composed of a wall panel or a PC plate, since the wall joint support of the building is projected from the outer wall surface by using the horizontal joint or the vertical joint which is a panel joint, the cross section having a cross section thinner than the joint width is used. Things will be used, and the resistance to compression and bending will become weaker. FIG. 5 shows an example in which a wall joint receiving metal fitting is projected using a vertical joint in an outer wall panel type house. That is, in the vertical joint portion 24 between the outer wall panels 23, 23,
Wall connecting support 2 to the web portion 25a of the pillar connector 25
The male screw portion 26a of 6 is attached. The male screw portion 27a of the wall joint material 27 is screwed into the female screw portion 26b of the wall joint receiving member 26.

[0003]

In the structure shown in FIG. 5, the outer wall panel 2 is attached to the male screw portion 26b of the wall connecting bracket 26.
Since a cross-section having a narrower width than the joint width between 3 and 23 is used, the resistance to the compressive force and the bending force is weak as described above, and buckling, bending, and bending are likely to occur at the male screw portion 26b. In addition, when an unexpected bending force such as an operator's stepping on the wall connecting material 27 is applied, the wall connecting member 26
May be damaged.

An object of the present invention is to easily attach the wall tie member of the scaffold to the wall tie member when connecting the wall tie member of the scaffold through the wall tie member and to increase the resistance of the wall tie member to various external forces. The object is to provide a wall joint reinforcement that can be reinforced.

[0005]

The wall joint receiving reinforcing metal article of the present invention comprises a bowl-shaped reinforcing metal article and a screw member penetrating the top of the reinforcing metal article.
The reinforcing hardware main body covers the wall joint receiving hardware projecting from the outer wall surface, and the peripheral edge portion thereof is capable of contacting the outer wall surface.
The screw member has an internal thread portion on the outside and an external thread portion on the inside.

[0006]

[Function] In this wall joint receiving reinforcing metal fitting, the peripheral portion of the bowl-shaped reinforcing metal fitting main body is pressed against the outer wall surface by screwing the male screw portion of the top provided on the main body of the reinforcing metal fitting into the wall joint receiving metal fitting. Then, in this state, the wall joint receiving hardware is covered by the reinforcing hardware main body. The tip screw portion of the wall connecting material is screwed into the female screw portion protruding outward from the top of the reinforcing metal body. As a result, the wall tie member is connected to the wall tie receiving metal fitting through the wall tie receiving metal fitting. By interposing the wall joint support metal in this way, even if shearing force or bending force acts on the wall joint material, it can be received by the bowl-shaped reinforcement metal body, so that the wall joint support metal A part of it is converted into tensile force and acts, and the resistance force increases.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 1, the wall joint receiving reinforcing metal member 1 is composed of a reinforcing metal member main body 2 and a screw member 3 provided at the top of the reinforcing metal member main body 2.

The reinforcing metal body 2 is formed in a bowl shape so as to cover the wall joint receiving metal 5 projecting from the outer wall surface, and the peripheral edge portion can abut against the outer wall surface. Packing 4 is provided. The screw member 3 has a female screw portion 3 a protruding to the outside of the reinforcing metal body 2 and a male screw portion 3 b protruding to the inside of the reinforcing metal body 2.

The wall joint support 5 has a male screw portion 5a and a female screw portion 5b, and the male screw portion 5a is joined to the column connector 6. The column connector 6 is a steel frame column made of C-shaped steel or the like, and the adjacent outer wall panels 7 and 7 are arranged so as to extend to the outer surface of the column connector 6 and are bolted to the column connector 6. In the web portion 6a of the pillar connector 6, a screw insertion hole is formed within the joint width of the vertical joint portion 8 formed between both outer wall panels 7, 7, and the above-mentioned back surface of the web portion 6a is formed so as to be aligned with the screw insertion hole. Male screw part 5 of wall joint bracket 5
A nut 9 (FIG. 2) for screwing a is fixed by welding. Instead of the back nut 9, a metal object with a screw hole (not shown) that fits within the joint width is fixed to the outer surface of the web 6a with a screw or the like, and the male screw portion 5a of the wall joint receiving metal object 5 is screwed into the screw hole. Is also good.

The connection of the scaffold wall tie member 10 using the wall tie receiving reinforcement metal 1 is performed by the procedure shown in FIG.
First, as shown in FIG. 2 (A), the male screw portion 5a of the wall joint receiving member 5 is screwed from the vertical joint portion 7 of the outer wall panel 7 to the nut 9 on the rear surface of the web portion 6a of the column connector 6. As a result, the wall joint receiving member 5 is attached to the column connector 6 in a state in which the female screw portion 5b thereof projects from the outer wall surface of the outer wall panel 7 to the outside.

As shown in FIG. 2B, the male screw portion 3b of the screw member 3 of the wall joint receiving reinforcing member 1 is screwed into the female screw portion 5b of the wall joint receiving member 5 thus mounted. As a result, the wall joint reinforcing metal fitting 1 covers the wall joint receiving metal fitting 5 in a state in which the rubber packing 4 at the peripheral portion of the reinforcing metal body 2 is pressed against the outer wall surface of the outer wall panel 6.

To the female threaded portion 3a of the threaded member 3 of the wall tie reinforcing metal 1, for example, a male threaded portion 10a at the tip of a commercially available wall tie material 10 as shown in FIGS. 1 and 2C is connected to connect the wall ties. The coupler 10b at the other end of the material 10 is connected to the scaffolding constituent material 12a of the pipe scaffolding 12 which is erected upright along the building 11 as shown in FIGS. 3 and 4.

According to the wall joint reinforcing metal member 1 having this structure,
Since the rubber packing 4 at the peripheral edge is pressed against the outer wall surface in the state in which the bowl-shaped reinforcing metal body 2 covers the wall joint receiving metal piece 5 projecting from the outer wall surface in this way, as shown in FIG. Even if an unexpected shearing force F or bending force M is applied by, for example, applying the foot A to the wall joint material 9, a part of the force is supported by the reinforcement metal body 2 of the wall joint reinforcement hardware 1 to support the wall joint. It is converted into a tensile force and transmitted to the receiving object 5. The wall tether 5 is generally strong in tension, which increases the yield strength of the wall tether 5. Further, part of the compressive force applied to the wall tie member 10 is borne by the wall tie receiving metal reinforcement 1, and the resistance of the wall tie receiving metal 5 to the compressive force is also improved.

Further, since the peripheral portion of the wall joint reinforcing metal member 1 is pressed against the outer wall surface via the rubber packing 4, the outer wall panel 7 is not damaged. Further, the wall-connecting reinforcing metal fitting 1 can be attached to the wall-connecting metal fitting 4 by simply screwing the male screw portion 3b on the inner side of the reinforcing metal-fitting body 2 into the female thread portion 5b of the wall-connecting metal fitting 5, so that the mounting work is also possible. It's easy.

In the above-described embodiment, the case where the wall joint receiving member 5 is provided by using the vertical joint of the outer wall panel type building has been described, but this is also applied when the wall joint receiving member 5 is provided by using the horizontal joint. The wall tie receiving reinforcement hardware 1 can be used in the same manner as described above. Further, the wall joint receiving reinforcing metal fitting of the present invention can be used in the case of a building other than the outer wall panel system building, and is not limited to the case of being used to reinforce the wall joint receiving metal fitting 5, and can be used for a temporary handrail receiver, a temporary ladder receiver, etc. Can also be used to reinforce these.
