Description

[Detailed explanation of the idea] This invention relates to a tool to assist in the erection of pillars at the time of construction.

In wooden construction, a plurality of columns with tenons at the lower ends are assembled in advance into a tower shape on a foundation made by drilling mortise holes at a predetermined pitch horizontally on the foundation concrete, and the columns are placed in the mortise holes. When erecting multiple pillars at the same time by aligning the tenons, a worker is assigned to each pillar and care is taken to ensure that the bottom end of the pillar does not separate from the foundation, but there are some small defects. Due to caution, the pillars were displaced from their bases, causing the pillars to jump up, causing damage to workers and delaying work.

This idea involves placing a vertical channel-shaped fixed frame in advance for each mortise hole in the foundation, and fitting the lower end of the oblique column into a channel-shaped rotating frame that is rotatably fitted into this fixed frame. The purpose is to provide a highly safe pillar erecting aid that prevents the pillar from coming off the base by fitting together and rotating the rotating frame using the fixed frame as a guide to erect the pillar. A specific example of this invention will be described using the drawings.

A vertical channel-shaped fixed frame 1 made by bending a steel plate is secured by a pair of side walls 3, 3 by bending both ends of a back wall 2 at right angles. 4 and 1
A channel-shaped rotating frame 6 composed of a pair of side walls 5, 5 is fitted, and of the three overlapping walls, the two side walls 3,
5, 3, 5 comrades are mounted on shaft 7, rotating frame 6 and fixed frame 1
The fixed frame 1 is pivotably mounted to the open side of one side of the fixed frame 1 around shafts 7, 7 inside.

Incidentally, when the three walls of the rotating frame 6 are inscribed and overlapped with the three walls of the fixed frame 1, the upper edges of the three walls of the rotating frame 6 largely extend beyond the fixed frame 1, and the back of the rotating frame 6 The upper edge of the wall 4 is formed with an ear portion 8 that curves outward in a large manner.

A support piece 9 is formed by bending the lower end extension of the back wall 2 of the fixed frame 1 at right angles to the outside, and is used to prevent the fixed frame from falling.

The auxiliary tools having the above structure are arranged at each mortise opening of the base A, and each of the auxiliary tools is fixed on the base using a fixing device so as to be stable.

Although there are many possible examples of this fixing device, a few preferred specific examples will be described in detail below.A leg plate with a width slightly smaller than the wall width W of the side wall 3 extends outward from the lower end edge of both side walls 3, 3 of the fixing frame 1. 10

A leg wall 13 is integrally formed with the leg plate 10 on the lower side, and a sharp inward protrusion 23 is protruded from approximately the center of the leg wall 13.

14.14 is a movable body that slides on the leg plate 10, and on one end edge of the base plate 15 that faces the leg plate 10, an extension part of the base plate 15 is bent and turned back to form a downward engaging groove 16;
The other end edge extension of 5 is bent upward and then folded back downward to form a vertical wall 17 upwardly and a leg wall 18 downwardly with the substrate 15 as the center. Also, a sharp inward protrusion 23 is provided protrudingly.

Note that instead of the downward engagement groove 16 of the rising piece 11 of the leg plate 10 and the movable body 14, an inward engagement groove 19 is formed in the rising piece 11 of the leg plate 10, and the downward retaining groove 16 of the movable body 14 is omitted. It is also possible to have a structure in which (see Fig. 5).

In the case shown in FIG. 4, the rising piece 11 of the leg plate is
or, in the case shown in FIG. 5, fit the outer edge 20 of the board of the movable body 14 into the inward retaining groove 19 of the leg plate 10, and then assemble the movable body 14 on the leg plate 10. , a tightening bolt 21 and a wing nut 22 are provided between the corresponding vertical walls 12 and 17 of the leg plate 10 and the movable body 14.
are arranged, and the vertical walls 12 and 17 are fastened inwardly to each other.

In addition, as another fixing device, a fixing frame 1 as shown in FIG.
A rising piece 11 parallel to the side wall 3 of the fixed frame 1 is formed at the tip of both leg plates 10 and 10 extending horizontally outward from the lower end edges of both side walls 3, 3. 1
On the other side edge of the fixing frame 1, an extension part of the leg plate 10 is bent downward at right angles to form a leg wall 13, which corresponds to the extension line of the back wall 2 of the fixed frame 1. A sharp inward protrusion 23 is provided in the center of the coast.

A movable plate 3 is superimposed on the leg plate 10 and has both edges abutted against the rising piece 11 and the side wall 3 of the fixed frame 1.
0 is arranged, and a plurality of through holes 31, 31 are bored in the approximately central part of the movable plate 30 in the front-rear direction parallel to the side wall 3, penetrating the leg plate 10, and opening the through holes 31, 31. A wing nut 3 is attached to the screw shaft 32 that selects one and projects onto the movable plate 30.
3 is screwed on, and the movable plate 30 is fixed onto the leg plate 10 so that the amount of extension from the leg plate 10 can be changed.

Also, one end edge of the movable plate 30 has an integrated horizontal rod 3 along the edge.
4 is suspended horizontally, and one or more inwardly pointed sharp claws 35 are attached to the lower end, and a pendulum wheel 36 that can be turned around in position is attached to the upper end for the purpose of controlling the movement of the center of gravity. The horizontal rod 34 is inserted into the body of the wide rod 37, and the locking wide rod 37 is attached to be swingable around the horizontal rod 34 and movable along the horizontal rod 34.

Further, as shown in FIG. 7, as a modification of the large locking rod 37, a leg plate 1 is provided with a leg wall 13 extending downward on one end edge.
A sharp inward claw 41 is attached to the lower end of the lower curved body 40 on the horizontal rod 34 horizontally suspended on the opposite edge of the leg wall, and a center of gravity is attached to the upper end of the straight body 42 connected above the curved body 40. The hook body 43 is fitted with a pendulum wheel 36 that can be turned back in position and has the purpose of operating the movement of the pendulum. It is pivoted so that it can move.

Next, the fixing work of the auxiliary tool using the fixing device will be explained in order. In the case shown in Figs. , the leg walls 13 and 18 of the leg plate 10 and the movable body 14 are held from the sides of the base A while adjusting the spacing between them to match the width of the base A, and the bolt 21 is inserted between the pair of vertical walls 12 and 17. The auxiliary tool is inserted and fixed onto the base A by tightening the wing nut 22.

In the case of FIG. 6, the movable plate 30 is moved according to the width of the base A, the through hole 31 is selected, and the wing nut 33 is attached to the screw shaft 32.
The movable plate 30 is fixed on the leg plate 10 by tightening, and the locking wide rod 37 is moved along the horizontal rod 34 while avoiding the joints on the base A, and the claws 35 of the locking wide rod 37 are moved to the base A. The base A is supported from both sides by the leg wall 13 and the locking rod 37.

In the case of FIG. 7, the inward claws 41 of the hook body 43 are bitten into the side surfaces of the base A, and both sides of the base A are held between the leg wall 13 and the hook body 43.

During the fixing work to the base A, the inward protrusions 23 and 23 provided on the leg walls 13 and 18 are fixed to the base A by tightening bolts or by driving the claws of the locking rods 37 and hooks 43. The pendulum ring 36 attached to the upper end of the locking rod 37 and the hook body 43 is inserted into the side surface of the locking rod 37 to prevent the fixing device from shifting. By rotating and positioning the hook body 43 inside, the center of gravity is moved, and the locking wide rod 37 and the hook body 43 are rotated to the side rod 3.
A clockwise rotational force is applied to the leg wall 13 around the leg wall 13.
The distance between the locking rod 37 and the hook body 43 is increased to make it easier to attach the fixing device to the base. This helps keep the claws 35 and 41 locked to the base A.

After the plurality of auxiliary tools have been fixed on the base by the above operations, the rotating frame 6 is rotated 90 degrees from the fixed frame 1, and the lower end of the pillar is provided with a hozoni protruding from the lower end inside the rotating rotating frame 6 which is in an inverted position. The pillars, pre-assembled in the shape of a tower, are then slowly erected by supporting the lower end of each pillar with an auxiliary tool.

At this time, the fixed frame 1 is pushed by the lower end of the column, and as a result, the biting force of the locking rod and the claws 35, 41 of the hook body into the column side increases more and more.

Due to the presence of the auxiliary tool, the lower end of the column does not come off much further than the top of the base A. In other words, the lower end of the column is erected while being surrounded by the rotating frame 6, which prevents the lower end of the column from jumping up, making it safe. This makes it possible to erect columns with high efficiency, and also reduces the number of workers.

The column surface of the column that is being erected along with the construction frame 6 does not come into direct contact with the fixed frame 1, so there is no damage to the lower part of the column, and once the column is erected, it can be moved from above the fixed frame. The column is supported by a greatly extended pivot frame 6, which provides high safety, and the upper edge of the back wall 4 of the pivot frame 6, where the column tends to fall, is provided with an outwardly curved ear 8. It reduces the contact resistance with the surface and reliably prevents the occurrence of pillar scratches on this surface as well.

In addition, the supporting piece 9 disposed at the lower end of the back wall 2 of the fixed frame 1 is T
When this auxiliary tool is placed at the intersection of the bases assembled in a letter or cross shape, the support pieces 9 come into contact with the bases arranged in a cross shape, and prevent the auxiliary tool from falling backward. , can play a role in promoting the stability of the assistive device.
