Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a vertical straightening tool for a house frame.

[Problems to be Solved by Conventional Techniques and Inventions] In the case of wooden construction, when a so-called skeleton such as a foundation, a pillar, and a girder is completed, it is confirmed whether the skeleton accurately maintains a vertical state or a horizontal state, If not in the correct vertical position,
One of the workers went up to the girder and tied the rope to the girder, and several workers on the ground pulled the rope to correct the skeleton to a vertical state, erected a skeleton and fixed the skeleton. There is.

Since such a straightening method is troublesome, a method has been proposed in which the bar is hooked on a girder and the bar is pulled to correct the bar. An object of the present invention is to provide a vertical correction tool for a house frame in which the connecting structure is set to a special structure so that the rod can be bent and locked well with respect to the hook-shaped rod.

[Means for Solving the Problems]

 The gist of the present invention will be described with reference to the accompanying drawings.

Hook rod 3 fitted and locked to a girder 2 that constitutes a frame 4 of a house
A vertical window 11 is opened in the center of the base rod 3'of the base rod 3 ', and the base rod 3'is inserted into a connecting cylinder 8 provided at the tip of the main rod 1 and fitted into the vertical window 11. The hook 12 is pivotally attached to the connecting cylinder 8 so as to be able to swing back and forth by the shaft 12, and when the hook 3 is pulled up to the upper edge of the connecting cylinder 8 with respect to the hook 3 on the back side. A relief notch 9 is provided at the upper edge of the back side to allow 3 to fall to the back side, and a base end rod 3'of the hooked rod 3 that has fallen back on the opposite front cylinder wall can escape. The present invention relates to a verticality correcting tool for a house frame, which is provided with a portion 10.

[Action]

The hook 2 of the main rod 1 is locked to the girder 2 or the horizontal pillar 2'of the second floor constituting the frame 4 of the completed house, and the rope 6 is attached to the fastener 7 provided at the lower end of the main rod 1, for example. When they are connected and pulled by manpower or using a winder, the hook-shaped rod 3 is moved to the main rod 1.
With respect to the main rod 1, the main rod 1 is obliquely tuned in the pulling direction, and the pulling force can effectively act on the frame 4, without damaging the girder 2. The vertical state of the skeleton 4 can be easily corrected.

〔Example〕

The drawings show an embodiment of the present invention. FIGS. 1 to 4 show a first embodiment and FIG. 5 shows a second embodiment.

The first embodiment will be described.

The two rods are fitted and connected using the rotating nut cylinder 5, and the rotating nut cylinder 5 is rotated to form the main rod 1 so that it can extend and contract. The rods 3 are connected in series, and a ring-shaped stopper 7 for fixing the rope 6 is attached to the lower end of the main rod 1.

The swinging structure of the hook-like rod 3 and the main rod 1 is such that the vertical window 11 is provided at the center of the base-end rod 3'of the hook-like rod 3 fitted and locked to the girder 2 which constitutes the frame 4 of the house. Opened in the longitudinal direction, the base end rod 3'is inserted into the connecting cylinder 8 provided at the tip of the main rod 1, and the hook 12 is attached to the connecting cylinder 8 by the shaft 12 fitted in the vertically long window 11. An escape notch 9 is pivotally attached to the front and rear, and allows the hook-shaped rod 3 to fall to the back side when the hook-shaped rod 3 is pulled up to the upper edge of the back side of the connection tube 8 with respect to the hook-shaped rod 3. An escape opening 10 is provided at the upper edge of the back side, and a base end rod 3'of the hooked rod 3 which is laid back is provided at the opposite front side cylinder wall.

Therefore, if the hook 3 is hooked on the girder 2 and the main rod 1 is pulled,
The hook-like rod 3 is pulled out from the connecting cylinder 8 provided at the tip of the main rod 1, and the base end rod 3'of the hook-like rod 3 is provided with the escape notch 9 and the escape opening 10. Against a vertical window
The shaft 12 located at the lower end of the shaft 11 can be oscillated rearward in the state shown in FIG. 3, and when the hook-shaped rod 3 is raised and inserted into the connecting cylinder 8, the base of the hook-shaped rod 3 is moved. The end rod 3'is locked by the inner peripheral wall of the connecting cylinder 8 so that the swinging of the hook-like rod 3 with respect to the connecting cylinder 8 is locked.

Incidentally, it is desirable that this swinging structure is provided so as not to rattle in the left-right direction and swingable only in the rearward direction when the main rod 1 is in the vertical state as shown in the drawing.

By swinging the hook-shaped rod 3 with respect to the main rod 1, the main rod 1 can be tilted in the pulling direction, so that the pulling force effectively acts on the girder 2 and the girder 2 is not damaged and the operator who moves the girder frame is skeletonized. Therefore, the pulling operation can be performed at a position (arbitrary position) away from No. 4 by a desired distance.

The second embodiment differs from the first embodiment in the structure for expanding and contracting the main rod 1, and is composed of a locking rod 13, a locking pin 14, and a locking hole 15. The other structure is the same as that of the first embodiment.

[Effect of device]

Since the present invention is configured as described above, when the hook-shaped rod is locked to the girder and the main rod is pulled, the main rod is bent in an inclined state with respect to the hook-shaped rod in synchronization with the pulling direction. Without damaging the girder with the hook-shaped rod, and by hooking the hook-shaped rod to the girder with the connecting structure to the girder for this main rod and pulling the main rod, the hook-shaped rod will come out from the connecting tube provided at the tip of the main rod. In addition, the base rod of the hook-shaped rod is pulled out from the connecting cylinder provided with the escape notch and the escape opening in the state shown in Fig. 3 with the shaft located at the lower end of the vertical adjustment window as the fulcrum. When the hook-shaped rod is inserted into the connecting cylinder by raising the hook-shaped rod, the base rod of the hook-shaped rod is locked by the inner wall of the connecting cylinder to lock the hook-shaped rod with respect to the connecting cylinder. To provide a vertical correction tool for a house frame that can correct the verticality of a completed house frame that is extremely easy to handle That.
