Description

[Detailed description of the invention] This invention relates to a fixing device for an erecting aid for a pillar at the time of construction.

In wooden construction, a plurality of columns with tenons formed at the lower ends are assembled in 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 columns at the same time by aligning the tenons of the columns, a worker is assigned to each column.
Even though care is taken to ensure that the bottom end of the column does not separate from the base, the column may slip from the base due to slight carelessness, causing damage to the worker and delaying work. This was the cause of such things.

What was devised for this purpose was a pillar erection aid, in which a vertical channel-shaped fixing frame was placed in advance for each mortise hole in the base.
The lower end of the steel column is fitted into a channel-shaped rotating frame that is rotatably fitted into this fixed frame, and the fixed frame is used as a guide to rotate the rotating frame while the column is erected. The purpose is to secure the safety of the pillars by preventing them from separating from the base, and to facilitate the erection of the pillars.

These pillar erection aids are placed in each mortise hole drilled in the foundation, and are removed after the erection of one group of pillars assembled in a tower-like structure is completed, and then used to move on to the next group of pillars. Because the auxiliary tool is relocated for the erection work, it is desirable that the auxiliary tool be fixed and that its removal be strong and quick.

This invention satisfies these demands in the installation of auxiliary tools, and in the process of erecting columns, the lower end of the column of the rotating frame is held in place to create a strong pressing force that acts on the back wall side of the fixed frame when the rotating frame is erected. The lower end of the retaining leg, ρ, of the leg wall and engaging leg that embraces it from both sides of the base of the leg-seat-shaped fixture placed on both sides of the auxiliary tool, is effectively utilized. The inward-facing claws are made to bite into the side of the base more firmly, making the attachment of the auxiliary tool more secure.1. Next, a concrete example of the fixing device for the erecting aid of the ρ pillar proposed in (4) will be explained using a diagram.

First, for the sake of convenience, I will start by explaining the pillar erection aid. A vertical channel-shaped fixed frame 1 made of bent steel plates has a back wall 2 and a pair of side walls 3, 3 made by bending both ends of a clearing 2 at right angles. Into this fixed frame 1 is fitted a channel-shaped rotating frame 6, which is also composed of a back wall 4 and a pair of side walls 5, 5, and the side walls 3 of both frames among the three overlapping walls are fitted.
, 5.3.5 are mounted on a shaft 7, and are pivotally mounted in the fixed frame 1 by a rotating frame 6 so as to be rotatable about the shafts 7, 7 toward the open side of one side of the fixed frame 1. .

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 is largely curved outward.

Reference numeral 9 denotes a supporting piece 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 with the above structure are installed at each mortise opening of the base A, and the leg-seat-shaped fixing devices that stabilize these auxiliary tools on the base are shown in Figures 1, 2, and 4. As shown in , at the tips of both leg plates 10° 10, which are slightly narrower than the wall width W of the side walls 3 and extend horizontally outward from the lower end edges of the side walls 3, 3 of the fixed frame 1, A rising piece 11 is formed parallel to the side wall 3 of the fixed frame 1, and a rising piece 11 is formed on the other side edge of the leg plate 10 at a coincident opening approximately on an extension line of the back wall 2 of the fixed frame 1. The extension part is bent downward at a right angle to form a leg wall 13, and a sharp inward protrusion 12 is protruded from approximately the center of the leg wall 13.

A movable leg plate 10a is disposed on top of the leg plate 10 and has both edges abutted against the rising piece 11 and the side wall 3 of the fixed frame 1, and is located approximately at the center of the movable leg plate 10a. There are a plurality of through holes 14 in the front-rear direction parallel to the side wall 3.
14 is bored through the leg plate 10, and the through hole 14°1
4 is selected and the wing nut 16 is screwed onto the screw shaft 15 protruding above the movable leg plate 1σa, so that the movable leg plate 10a can be adjusted to change the amount of extension from the leg plate 10 by 4. It is firmly fixed on the leg plate 10.

Furthermore, two horizontal rods 17 are horizontally suspended along the two edges of the movable leg plate 10a, and one or more inwardly pointed claws 18 are provided at the lower end, and the center of gravity is moved at the upper end. Insert the horizontal rod 17 into the body of the square rod-shaped locking leg 20 to which the swing pre-inspection 19, which can be turned back and forth in position and has a white part that causes algae to form, is inserted. The tree is attached so as to be swingable around the horizontal rod 17 and movable upward along the horizontal rod 17.

In addition, as a modification of the square rod-shaped locking leg 20, a lower side is attached to a horizontal rod 17 that is suspended horizontally on the edge opposite to the leg wall of the leg plate 10, which has a leg-wall 13 extending downward on the two end edges. A sharp inward claw 18 is attached to the lower end of the curved side 21 of the curved side 21, and a pre-swing test 19 that can be freely turned back in position has the purpose of controlling the movement of the center of gravity at the upper end of the straight body 22 connected above the curved side 21. The connecting part of the curved side of the hook-shaped locking leg 23 and the straight body is inserted, and the locking leg 23 is pivotally connected to be able to swing around the horizontal rod 17 (Fig. 3). ,”Figure 5).

This auxiliary tool is made by rotating the fixed frame 1 of the rotating frame 6 by 90 degrees and fitting the lower end of the rotating frame 6 into the pillar with a tenon formed at the lower end. The group is slowly erected with the lower end of each group supported by an auxiliary tool.

Prior to the erection work of the pillar using this auxiliary tool, the fixing frame 1 is inserted into the fixing frame 1 in such a way that the mortise hole hole drilled in the base A is held inside the fixing frame 1.
In the case of the fixing device shown in FIGS. 1, 2, and 4, the movable leg plate 10a is placed on the base A, and the movable leg plate 10a is
The movable leg plate 10'□A□ is moved on the leg plate 10 by selecting the through hole 14 and tightening the wing nut 16 to the screw shaft 15.
is fixed, and the square rod-shaped locking leg 20 is moved along the horizontal rod 17 while avoiding the joints on the side of the base A.
Drive the nails 18 into the side of the base A, and the base A is attached to the leg wall 13.
It is held between both sleeves by the locking legs 20.

3 and 5, in the case of a fixed indicator mounting, the inward claws 18 of the curved hook-shaped locking legs 23 are bitten into the side surfaces of the base A, and both sides of the base A are connected to the leg walls 13 and the locking legs. Clamp at 23.

Further, the inward protrusion 12 provided on the leg wall 13 also serves as the retainer leg 20.2.
A part of the pawl 18 in No. 3 is dug into the side of the folding base A during the driving operation to prevent the seller from misaligning the auxiliary tool.

Also, the swing preliminary inspection 19 attached to the upper ends of the locking legs 20 and 23
is rotated to the inside of the locking legs 20 and 23 to move the center of gravity, and the locking legs 20 and '2
i' to apply a clockwise rotational force around the horizontal rod 17, and increase the distance between the leg wall 13 and the claw 18 by 1 meter.
The attachment of the auxiliary tool to the base is made easy, and after the work is completed, the winter melon 18. □This auxiliary tool is placed at each lower end of the group of pillars that are assembled into a tower shape as a group, and the two or more pillars that help maintain the Ig's base and lock are placed. Every time the pillar group verification work is completed, the auxiliary tools are relocated and the pillar group erection work is carried out.
In the fixing work, the inward claws dig into the side of the base A by hitting the outer lower end of the locking leg, and during the removal work. Inward claw 18 by striking the outer upper end of the locking leg
can be pulled out from the side of the base, allowing quick relocation of auxiliary tools. Also, when the column is being erected, the fixed frame 1 is strongly pushed toward the back wall at the bottom end of the column, and the fixed frame A force acts on the person's back to prevent him from falling.

In the locking legs that work to prevent the fixed frame from falling backwards, the biting force of the inward-facing claws into the side of the base is further increased, and the force of fixing the auxiliary tool on the base is increased. It has the effect of increasing the number of people.

In addition, in the case of the square rod-shaped locking legs shown in Figures 1, 2, and 4, the locking legs are in a substantially vertical state when the claws are driven into the base. is the most desirable in terms of maintaining the engagement force, and therefore, the movable leg plate 10a can be moved appropriately to easily bring the locking leg into its optimum state, and the base of the claw portion of the locking leg can be easily maintained. The angular shape of the locking legs is effective in smoothly performing the work when hammering for driving in and releasing.

On the other hand, in the case of the curved hook-shaped locking legs shown in Figures 3 and 5, the foothold can be held in place by hugging the base with the locking leg, so it can be used instantly for several types of bases with different widths. This makes the fixing work easier and has a hanging effect.
