Description

[Detailed Description of the Invention] The present invention relates to a clamp used to temporarily fasten the long press to the lintel when the long press is attached and fixed to the lintel.

Conventional clamps of this type include
There is one shown in the figure. In the same figure, 1 is an inverted J-shaped receiving member, and the receiving surface 1 is at the tip of the short rod side.
A is formed, and a receiving piece 1b extending in the same plane as the short rod is formed on the long rod side, and a spiral tube 1c is formed at the tip thereof. Reference numeral 2 designates a screw screw screwed into the screw tube 1c, and a tightening plate 2a is rotatably attached to its upper end, and a grip 2b is attached to its lower end. Note that 2c is the tightening board 2
This is a backing plate such as a rubber disc that is glued to the top surface of a.

Next, when screwing or nailing the long press 3 to the lintel 4, when temporarily fastening the long press 3 to the lintel 4, place the long press 3 on the top of the lintel 4, and place the long press 3 on the receiving surface of the receiving member 1. Long press 1a Horizontal part 3a of 3
Then, hold the spiral tube 2 and turn 2b to raise it, and the contact plate 2c comes into contact with the lower surface of the lintel 4 and tightens. As a result, the long press 3 is fixed to the upper surface of the lintel 4.

By the way, after temporarily fixing the long press 3 to the top surface of the lintel 4, the long press 3 is fixed to the lintel 4 with screws or nails, but since this screwing or nailing is difficult for the worker to see, The drawback was that accurate screwing or nailing could not be performed.

The present invention was developed in view of the above points, and is a method in which a receiving tube is formed on the receiving surface of the receiving member, and screws or nails are inserted into this receiving tube to perform screwing or nailing work. The object of the present invention is to provide a clamp that improves workability and allows screwing and nailing to be performed at accurate positions.

In addition, in the present invention, the screw rod can be freely rotated and locked with respect to the receiving member via the shaft rod, so the tightening plate of the screw rod can be moved in the opposite direction from the receiving surface until the receiving surface of the receiving member comes into contact with the long press. To provide a clamp which greatly improves tightening work by rotating the bolt to the side, bringing the receiving surface into contact with the long press, and then rotating the screw rod toward the lintel side and positioning the tightening plate under the lintel. The purpose is to

An embodiment of the present invention will be described below with reference to FIGS. 2 to 4. Note that the same reference numerals as in FIG. 1 indicate the same members, and explanations thereof will be omitted.

In this embodiment, a shaft tube 6 is inserted into the tip of the long rod side of the receiving member 1, and this shaft tube 6 is rotatable between a stopper 1c formed on the receiving member 1 and a nut 7. The receiving member 1 has several recesses 1d.
is formed, and a small hole 6 formed in the shaft tube 6
The pole 8 inside a is fitted. Note that the pawl 8 is given elasticity by a plate spring 9 having a C-shaped cross section and annular shape wound around the outer circumference of the shaft tube 6, and by rotating the shaft tube 6, the pawl 8 is sequentially moved to another position. Recess 1
It is inserted into d. 10 is a receiving piece fixed to the shaft tube 6, and a spiral tube 11 is fixed to the tip thereof.

Further, this embodiment differs from conventional clamps in that a pipe 1e is integrally formed on a receiving surface 1a formed at the tip of the short rod side of the receiving member 1.

The method of using the clamp in this embodiment will now be described with reference to FIG. 4.The long press 3 is fixed to the lintel 4 by tightening the screw rod 2 in the same manner as in the prior art. At this time, the pipe 1e is located on the top surface of the long press 3, so
A screw 12 is inserted into this pipe 1e, and screwed into the lintel 4 through a long press 3 using an electric screwdriver 13 or the like. Thereby, the screw 12 is screwed straight into the correct position.

In the above embodiment, the screw 12 is screwed in, but it goes without saying that the screw 12 may also be a nail.

Further, in the embodiment, the pipe 1e formed on the receiving surface 1a is one piece, but this pipe 1e
may be two or more, and the structure of the clamp body may be any known structure. The key point is to form the pipe 1e on the receiving surface 1a of the clamp.

As mentioned above, the present invention has the pipe integrally formed on the receiving surface formed on the receiving member.
When tightening, screwing or nailing two parts like a long press and a lintel, insert a screw or nail into the pipe and drive it in with a screwdriver or hammer to integrate the two parts. can be screwed or driven straight into a predetermined position, and since the screw rod is rotatable and lockable relative to the receiving member via the shaft rod, until the receiving surface of the receiving member comes into contact with the long press. Rotate the tightening plate of the screw rod in the opposite direction from the receiving surface,
After the receiving surface is brought into contact with the long press, the screw rod is rotated toward the lintel and the tightening plate is positioned under the lintel, which has the effect of greatly improving the tightening work.

Claims (1)

[Claims for Utility Model Registration] A receiving member in which a receiving surface is formed at the tip of the short rod in an inverted J shape, and a pipe parallel to the short rod is formed in a portion extending from the receiving surface; A shaft tube that is freely inserted into the tip of the long rod side of the receiving member only in the rotational direction and locked at a desired rotation angle; a spiral tube fixed to the shaft tube via a receiving piece; A clamp, characterized in that it moves up and down by being screwed together and rotated, and has a threaded rod that allows a tightening plate rotatably attached to the tip to approach and separate from the receiving surface of the receiving member.
