Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a push-pull attachment for a support for reinforcing a frame such as a formwork used in concrete construction of a building during concrete construction.

[0002]

[Prior art]

 Frames such as formwork are used when concrete is used to construct vertical columns or walls of concrete structures such as high-rise buildings. The vertical columns and walls are formed by inserting reinforcing bars into the assembled frame and placing concrete in the voids. The concrete cast in the frame is made of a fluid immediately after the casting and gradually hardened. When the fluid concrete is filled in the frame, the frame receives a pressing force from the inside. This pressing force increases toward the bottom of the frame. If the frame body is deformed by the action of the pressing force from the inside, the standing pillars and walls of the prescribed shape will not be constructed. In addition, the quality of the finished product is also reduced. For this reason, conventionally, the frame body has been constrained by fasteners to prevent deformation.

FIG. 11 shows an example of a conventional technique. Reinforcing bars 10 are erected in the frame 1d for the upright columns, and concrete 11 is filled during the construction. Around the frame 1d, a chain 33, which is one of the fasteners for the frame 1d for preventing the deformation of the frame 1d, is wound up and down, for example. The chain 33 is tightly wound around the frame 1d by tightening means (not shown). On the other hand, a push-pull support member 34 is installed between the frame body 1d and the horizontal existing surface 8 in order to prevent the frame body 1d from being reinforced and tilted and to keep the frame body 1d in a vertical state. As the push-pull support member 34, a rod-shaped body that is laid along the horizontal direction has been conventionally used.

[0004]

[Problems to be solved by the device]

 The conventional support structure for the frame 1d shown in FIG. 10 has the following problems. First, since the push-pull support member 34 that supports the frame 1d is arranged in the horizontal direction, the reinforcing support force of the frame 1d becomes insufficient. Moreover, the frame 1d may be displaced upward. Further, as shown in FIG. 11, there is a risk of interfering with the electric wires 35 and the like installed near the frame 1d. The frame 1d is tightened by the chain 33. The chain 33 has a problem that the frame 1 d is deformed during concrete construction in which tightening is insufficient. Further, depending on the installation location of the frame 1d, it may be difficult to dispose the support member 34.

The present invention solves the above problems, and the frame is securely reinforced and supported without deformation during concrete construction, its supporting strength can be adjusted, and its handleability is good. The purpose of the present invention is to provide a push-pull attachment for supporting a frame that can be installed in a relatively narrow space.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention is a push-pull attachment for support for reinforcement of a frame framed for concrete pouring during concrete construction. It is installed between the locking tool that is removably fixed to the frame body tightening pipe that is installed and the locking tool and the horizontal existing surface on which concrete has been installed, and is inclined at an angle θ with respect to the horizontal existing surface. A push-pull attachment for a frame is provided, which includes a push-pull support member that is disposed as a unit and an extender that is integrally attached to the member and that adjusts the expansion and contraction of the member along the axial direction thereof. To do. More specifically, the above-mentioned locking tool is characterized by forming an arc-shaped portion to which the hook-shaped locking portion of the push-pull support member can be attached. Further, the elastic device is a turnbuckle. Further, a plurality of push-pull support members may be installed between the upper side and the lower side of the frame body at appropriate intervals. Further, the angle θ of the plurality of push-pull support members is 20 [°] or more and 70 [°] or less. Furthermore, the angle θ of the push-pull support member is such that the lower side of the frame is smaller than the upper side. Further, the push-pull support member is characterized by a push-pull attachment tool for supporting a frame body in which a plurality of sets of the lower side of the frame body are arranged from the upper side.

[0007]

[Action]

 First, the periphery of the frame is tightened with the tightening tube. A locking tool is attached to the tightening pipe body, and a push-pull support member is installed between the locking tool and the horizontal existing surface at an angle θ with respect to the horizontal existing surface. Plural sets of push-pull support members will be installed above and below, respectively. The support member is expanded / contracted along the axial direction by an expander / contractor integrally attached to the push / pull support member to adjust the support strength of the frame body. Since the push-pull support member and the locking device are structured such that the hook-shaped locking part of the push-pull support member is attached to the arc-shaped part of the locking device, the push-pull support member is inclined. Even if it is erected, it will be arranged comfortably. Since the lower side of the frame receives more pressing force than the upper side during concrete filling, a larger number of pushing / pulling support members are arranged on the lower side than on the upper side. The angle θ is preferably about 45 °, but the angle θ is smaller than that on the upper side because the lower push-pull support member receives a large force. As described above, the frame body is reinforced and held in the vertical state without being deformed. Further, the support rigidity is effectively achieved by setting the inclination angle of the support member to 20 [°] or more and 70 [°] or less. Also, by arranging the push-pull support member at an angle, there is no interference with surrounding electric wires and the like, and the push-pull support member can be provided in a relatively narrow space.
