Abstract

PURPOSE:To efficiently assemble a brace by arranging a brace member grasping device for clamping a turnbuckle and a threaded round bar. CONSTITUTION:Many streaks of threaded round bars 10 are parallelly grasped by a brace member grasping device 7. Next by a brace member terminal holding socket 9 mounted to an impact wrench 11, a turnbuckle 12 is screwed in its terminal successively to the threaded round bar 10 grasped in parallel. There after, a grasped position of the threaded round bar 10, with the turnbuckle 12 screwed, is moved to a part of the turnbuckle 12. To the trunbuckle 12 of this threaded round bar 10 moved grasped in parallel, a different threaded round bar is similarly successively screwed, building a brace.

Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a method for assembling braces used as building members and a device used therefor, and particularly, its purpose is to significantly improve the efficiency of assembly work. .

(Prior Art) Generally, a brace is assembled by assembling threaded round rods of various lengths and turnbuckles in advance before going to a construction site.

However, this work was troublesome when there were a large number of pieces.

In other words, if the threaded round bar has long and short lengths, first hold the long object in a vice, turn the turnbuckles one by one by hand, and thread them together, then adjust the grip position to the turnbuckle. After moving it, I screwed together a short threaded round rod.

Because they were turned by hand, efficiency was low, and working with multiple pieces was extremely difficult and made the hands hurt.

Therefore, hand-turning devices such as turnbuckles or handles that were rotated by grasping the end of a threaded round bar were used, but these remained inefficient.

(Problem to be solved by the invention) This invention was made in order to improve the above-mentioned inefficiency and relieve hand pain. The aim is to double the efficiency.

(Means for solving problems) First, the configuration of the apparatus of the present invention will be explained based on the drawings.

The device is a turnbuckle (+2) or a threaded round bar 00)
It consists of a brace member gripping device C) for gripping and holding the brace member, and a brace member end holding socket (9) used separately when screwing.

Brace member gripping device C'? ) consists of two square rods (υ■) stacked one above the other, with a gap adjustment member ■ between the two upper and lower square rods at one end, and an upper square rod ( υ is divided, and the long side end is located on the short side extension piece (4), and is fixed to the extension piece (4) at a fulcrum (■) that can rotate at the above-mentioned upper part. The square rod ■ can be opened and closed with respect to the lower square rod ■, and the other end has a tightening member (6) for tightening between the upper and lower square rods (1) and (2). Basic configuration.

The space between the upper and lower corner bars (1) and (2) above is a gripping part, so if the material is wood, you can leave it as is, but if it is made of metal, an elastic plate (Ll) should be attached. It is necessary to keep it.

The brace member terminal holding socket (■) is made by fitting a bottomed cylindrical elastic material (8) with a tapered inner circumferential surface into a hard body such as metal whose inner circumferential surface has an approximate shape. This is the basic configuration.

In this case, it is preferable to make the part connected to the impact wrench (11) a one-touch type (tin (1)) so that it can be easily replaced. This is because it is necessary to prepare several different sizes depending on the thickness.

In addition, the maximum inner diameter of the brace member terminal holding socket ■ is as follows:
It is necessary to make the diameter of the threaded round bar θΦ or turnbuckle (121) thicker than the diameter of the end.

Next, the assembly method will be described.

The brace assembly method consists of the following steps.

(B) First step of gripping a large number of threaded round bars θ in parallel on the brace member gripping device (7) (I2) The brace member terminal holding socket attached to the impact wrench (11) ■ At the turnbuckle (121 terminal,
The second step of sequentially screwing into the threaded round rods θ held in parallel (moving the gripping position of the threaded round rod θΦ onto which the turnbuckle (121 is screwed) to the turnbuckle (12)) The third step (=) moves and holds the threaded round bar θ0 in parallel.
) turnbuckle (121), attach another threaded round bar,
4th step of sequentially screwing in the same way as the 2nd step Note that, of course, if the threaded round bar 0ω comes in two types, long and short, and you are assembling them, the long one is the first step, and the short one is the first step. This may be the fourth step.

(Function) The brace member gripping device (7) is adjusted with the gap adjustment member ■ to approximate the width of the object to be gripped, and the upper square rod ■
Lift it upward to the position indicated by the chain line as shown by the arrow, arrange the threaded round rods 00) or turnbuckles (121) in parallel at appropriate intervals, and tighten them with the tightening member 0, then the fulcrum ((6) At the center is the extension piece (push down 4, so
As a result, the gap adjustment member (2) is used as a lever fulcrum for pressure contact.

The brace member terminal holding socket (9) is attached to the impact wrench (II) and pressed against the end of the threaded round bar (10) or turnbuckle (12) held by the impact wrench (11). ), the screwing progresses easily without slipping due to friction with the elastic material (8).

When removing or moving the threaded round bar (10) or turnbuckle (@), loosen the tightening member (6) and move it away from the end of the upper square bar (υ) to the position shown by the chain line as shown by the arrow. All you have to do is lift the square rod (1).

(Example) When rotated, both the upper square rod (1) and the lower square rod ■ are made of channel-shaped steel material, and the fulcrum (■ Since it is cut off, it is possible to stand still in a vertical position so that the upper square rod (2) leans against the gap adjustment member (2) when lifted.

In addition, to make it easier to tighten the threaded round rod (1Φ) and turnbuckle (121), an elastic plate (yellow rubber plate) was attached.

Note that the tightening member (2) has a rotating handle for easy operation. Then, in order to rotate it in the direction shown by the arrow, there were notches (4) at the ends of the upper corner rod (1) and the lower corner rod (2), so that they would stop at the stopper (1).

θ is a pivot point for the tightening member (6), and (18) is a handle for lifting the upper square rod 0).

The brace member terminal holding socket (9) shown in Figure 2 is of a one-touch type (impact wrench θ1 with a mallet), and is made of elastic material (8), binding material (5), soft rubber material, and is a consumable item. In order to make it easier to replace, all you have to do is simply fit it on.

(!! is a collar to prevent it from falling off, and although it is provided at the bottom, it is not limited to being rotated, and may be placed elsewhere.

(Effect) As a brace member gripping device a), if the upper square rod ■ and the lower square rod ■ are made longer, it is possible to grip and hold a large number of threaded round rods θΦ and turnbuckles (@). However, unlike the fulcrum (5), the lever fulcrum during gripping becomes 0 part of the gap adjustment member via the extension piece (4), so it can be pressed based on the pre-adjusted gap, and there is some pressure around the fulcrum. This creates a margin and provides an appropriate gripping force.

The brace member terminal holding socket ■ is made of elastic material (
8) Since the inner peripheral surface of
It can hold the end of the holder, and when it wears out, it can be replaced easily by simply fitting it on and taking it off.

As for the assembly method, it is possible to hold a large number of books at once, and they are screwed in one after the other with an impact wrench (10), so it is incomparably more efficient by several tens of times than the traditional method of doing it by hand. This is an industrially useful invention since it is not tiring at all, and the device has a simple configuration and can be provided at low cost.
