[Detailed description of the invention]

[0001]

The present invention relates to construction and civil engineering works, for example, combining two steel frames made of H steel, combining a steel frame with a jack base standing on the steel frame, or combining two steel frames. The present invention relates to a connecting device capable of connecting a support to a steel frame.

[0002]

2. Description of the Related Art In the case where a column is connected to a steel frame made of H steel or a chain or the like is similarly connected to a steel frame, Japanese Utility Model Publication No. Sho 62-4131 and Japanese Utility Model Application Laid-Open No. Sho 59-228 are used.
A joint fitting as disclosed in Japanese Patent Publication No. 52 has been developed. These joining brackets comprise a bracket body having a U-shaped cross section and two upper and lower holding pieces, a porto movably screwed to one of the holding pieces, and a clamp or hanging tool connected to the fitting body. Insert a steel frame flange between the two holding pieces, hold this flange with one holding piece and a bolt,
A post is inserted into the clamp, and a chain is attached to the hanging device.

[0003]

However, in the above-mentioned joint, the flange of the steel frame is clamped by one of the clamping pieces and the bolt, so that a large unbalanced load is applied to the bracket body through the steel frame or the support or the chain. When the load is applied, the load acts on the bolt or acts on the plate at the tip of the bolt, and the bolt may be bent or the plate may be damaged. Further, the end surface of the bolt and the plate provided on the bolt have a small contact area with the flange of the steel frame and are pressed and clamped with the bolt, so that the clamping force is weak, and the steel frame may be displaced or come off.

Accordingly, an object of the present invention is to provide a connecting device which does not bend or break a bolt or the like and has a strong clamping force.

[0005]

In order to achieve the above object, a first configuration of the present invention comprises a first arm, a second arm detachably connected to the first arm, and a second arm. A bolt detachably inserted between the first and second arms, a nut screwed to an end of the bolt, a boss provided on the second arm, and a tip provided on the tip of the first and second arms; The first arm is formed in an L-shape by a clamping body and a bifurcated engaging piece extending laterally from a base end of the body, and the second arm is formed by a clamping body. And an engaging piece extending laterally from the base end of the main body, and formed into an L shape, wherein the engaging piece of the second arm is detachably fitted between the forked engaging pieces of the first arm. The bolt is inserted approximately in the middle of each of the main bodies of the first and second arms, and the boss is provided so as to protrude from the outer surface of the engaging piece of the second arm. Skidproof first, and is characterized in that provided at the tip of each body of the second arm. Similarly, a second configuration of the present invention includes a first arm, a second arm detachably connected to the first arm, and a bolt detachably inserted between the first and second arms. , A nut screwed to the end of the bolt, a boss provided on the second arm, and a non-slip member provided on the tip of the first and second arms, wherein the first arm is a clamping body. When,
The second arm is formed into an L-shape with a bifurcated engaging piece extending laterally from the base end of the main body, and the second arm is formed by an engaging piece extending laterally from the base end of the main body. The engagement piece of the second arm is removably fitted between the fork-shaped engagement pieces of the first arm, and the bolt is provided substantially at the center of each body of the first and second arms. Is inserted, the boss is provided to protrude on the outer surface of the engagement piece of the second arm, and the anti-slip member is
A bracket is provided at the tip of each main body of the second arm, and a bracket is rotatably provided on the boss, and a clamp is rotatably connected to the bracket via a universal joint. in this case,
Preferably, the non-slip member is composed of saw-toothed teeth, irregularities or spike-shaped projections in cross section.

[0006]

The steel flange made of H steel is overlapped with two flanges or the steel flange and the base of a jack standing on the steel are overlapped and inserted between the first and second main bodies, and each main body is moved toward each other. When tightened with bolts and nuts,
The two main bodies hold the upper and lower flanges or the flange and the base as holding pieces. At this time, since the bolt acts on each body in the pulling direction, the clamping force between the two bodies is strong. or,
Since the slip of the main body is prevented by the non-slip member provided on each main body, the main body is hardly disengaged.

When the nut 4 is screwed into the screw 3b of the bolt 3, the second arm 2 moves in the direction approaching the first foom 1 and is tightened, and the two arms 2 inserted between the first and second arms 1 and 2 are tightened. A member, for example, a flange portion of a steel frame made of two H steels is sandwiched, and the two steel frames are joined. At this time, the engagement pieces 13 of the second arm 2 are connected to the two engagement pieces 11 of the first arm 1,
11 slides along the gap 9 or groove formed therebetween. Non-slip members 6 provided at the tips of the main bodies 10 and 12 of the first and second arms 1 and 2 have sawtooth-shaped teeth 16 in cross section.
Or a sharp projection 1 provided in the vertical and horizontal directions shown in FIG.
7, 18, the spike-shaped projection 19 shown in FIG. The boss 5 is provided so as to protrude outside the second arm 2, for example, on the outer surface of the base end of the engagement piece 13, and a bifurcated bracket 8 is provided in a shaft hole of the boss 5 via a shaft 7 with an arrow Y ( As shown in FIG. 1), they are connected rotatably in the horizontal direction. The boss 5 may be provided outside the engagement piece 11 of the first arm 1. The shaft 7 has upper and lower ends formed with flanges, nuts or thick portions 7a for retaining. Clamp C is attached to bracket 8 via universal joint 9.
Are rotatably connected, and the clamp C is rotatable. The universal joint 9 includes a shaft 9a and flanges 9b and 9c at both ends. The flanges 9b and 9c are rotatably engaged with the bracket 8 and the clamp C, respectively. The clamp C has two first and second holding pieces 1.

1) According to the first aspect of the present invention, since there are provided two first and second arms and a bolt inserted between the main bodies of the first and second arms, The first and second arms are vertically guided by bolts, and the two attached members inserted between the two arms are clamped by the main bodies of the two arms by tightening nuts, and are strongly connected. You. At this time, the bolt tightens the main body of the second arm with respect to the main body of the first arm in the pulling direction, so that the tightening force is strong, and the displacement of the two mounted members cooperates with the anti-slip member. This prevents the connecting device itself from falling off. Further, even if an eccentric load from the attached member acts on the first and second arms, the first and second bodies carry the same, and it is possible to prevent the bolt from being bent or damaged. Further, since the second arm is provided with a boss, other clamps, chains, and other members can be attached using the boss. 2) According to the invention of claim 2, since the clamp is provided via the boss, the first and second arms are connected to, for example, a steel frame, and the scaffold or the support column is clamped via the clamp. And the struts can be joined close to the steel frame. The clamps can be rotated horizontally or vertically via the bracket and universal joint, and the columns can be joined by rotating the clamps even if the columns are standing upright or placed horizontally. it can. Moreover, even if the position of the support is not located at a fixed position, the clamp can be moved to the position of the support by rotating the bracket horizontally.
