DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connecting clamp interposed between a holding member and a held member and connecting the holding member and the held member.

[0002]

2. Description of the Related Art In various plant constructions, wiring to various devices, wiring to lighting, and the like are sometimes performed using special cables such as armored cables. There are advantages such as laying is not required, the construction period can be shortened, and maintenance is facilitated. This special cable wiring is a method in which a support member is welded to a pipe rack on the skeleton side, such as C-chan, H steel or an L-shaped angle, and a cable is fixed to the support member.

[0003]

However, in such a wiring method, there is a problem that the coating on the skeleton side is melted or burnt at the time of welding. However, it was pointed out that there was a risk of rusting and, at worst, decay. In addition, when the welding location is at a high place, the equipment and preparation for the arc welding and gas welding are complicated, and the safety of working at a high place may be impaired.
Such a problem is a great disadvantage in the wiring work in which it is necessary to narrow the mounting interval of the support member due to the flexibility of the cable, and the number of welding steps increases accordingly. Therefore, there has been a demand for an apparatus and a wiring method that can wire a cable without performing welding work.

Accordingly, the present invention firstly provides an apparatus for fixing a held member such as a support member to a holding member such as a C channel, H steel or an L-shaped angle on the skeleton side without welding, and Thirdly, an object of the present invention is to provide a method of attaching the device, and thirdly, to provide a wiring method "without welding" using the device.

[0005]

SUMMARY OF THE INVENTION The present invention utilizes a "lever" function or a "moment of force" acting on a point when rotating an object around that point, thereby clamping the holding member to the holding member. Is a coupling clamp configured to exert a tightening force and thus an occlusal force. Specifically, as described in claim 1, a connecting clamp interposed between the holding member and the held member, and connecting the holding member and the holding member, the connecting clamp is a concave portion that receives one end of the holding member, The concave portion is formed, and a clamp portion including an upper jaw portion and a lower jaw portion that abuts on the front and back surfaces of one end of the holding member, and a fixing portion that fixes the held member, and the tip of the upper jaw portion is The load of the held member fixed to the fixing portion and located closer to the tip of the holding member than the tip of the lower jaw acts to increase the tightening force of the upper and lower jaws against one end of the holding member.

Here, the holding member is a member constituting a structure, for example, an H-shaped steel, a channel steel (C-channel), a T-shaped steel, an angle steel, etc., which are fixed to the skeleton side of a building. (L-shaped angle, angle material) and the like. The held member is a member that is held by the holding member via a connecting clamp, and refers to, for example, a support member that fixes a cable in wiring work. Further, in order to increase the tightening force of the upper jaw and the lower jaw by the load of the held member fixed to the fixing portion, the position at which the load of the held member is applied to the tightening force of the upper jaw and the lower jaw. What is necessary is just to provide a fixing | fixed part.
In other words, the fixing portion only needs to be at a position where the distance between the tip of the upper jaw portion with respect to the holding member surface and the line of action of the load force of the held member can be obtained from the action of the “moment of force”. It suffices if the position is such that the distance from the lower jaw tip to the back surface of the member and the line of action of the load force of the held member can be taken.

[0007] In addition to the fixing portion, the tip of the upper jaw is located closer to the tip of the holding member than the tip of the lower jaw, so that the weight of the held member fixed to the fixing portion at a predetermined position is reduced. By the action, the connecting clamp exerts a rotating force on the holding member in an outward direction around the respective tips of the upper jaw and the lower jaw. Therefore, since the tightening pressure of the upper jaw and the lower jaw of the clamp portion increases in proportion to the weight of the held member, the held member can be fixed to the skeleton side via the connection clamp without welding. it can.

According to a second aspect of the present invention, there is provided a connecting clamp having a different configuration for reliably exerting the action of the load on the held member, the connecting clamp includes a recess for receiving one end of the holding member, A concave portion is formed, and a clamp portion including an upper jaw portion and a lower jaw portion that abuts on the front and back surfaces of one end of the holding member, and a fixing portion that fixes a held member, and the concave portion faces the holding member. An insertion opening corresponding to the plate thickness of one end of the holding member is formed between each end of the upper jaw and the lower jaw, and one end of the holding member inserted through the insertion opening is connected to the upper jaw and the lower jaw. The clamp portion is provided with a rotation space in which the clamp portion turns outwardly of the holding member until the fixing portion is tightened, and the fixing portion includes a mounting surface provided on the bottom of the lower jaw and a screw hole.

According to this structure, the insertion opening corresponds to the thickness of one end of the holding member and is formed between the opposed upper jaw and lower jaw. The upper jaw and the lower jaw gradually tighten the upper and lower jaws of the holding member and further engage with each other as the connecting clamp is rotated outward of the holding member in the rotation space. become. In addition, since the fixing portion is provided at the bottom of the lower jaw, the distance between the tip of each of the upper jaw and the lower jaw with respect to the front and back surfaces of the holding member and the line of action of the load force of the held member can be secured. The tightening force and the occlusal force of the upper jaw and the lower jaw of the clamp part increase in proportion to the weight of the holding member. Therefore, the upper and lower jaws of the clamp portion securely tighten the holding member, and the held member can be fixed to the skeleton side without welding via the connecting clamp.

In the above invention, as described in claim 3, the lower jaw has a slide surface that slides on the back surface of the holding member when one end of the holding member is inserted through the insertion opening. On the other hand, the upper jaw may be a contact surface that comes into contact with the surface of the holding member when the clamp is rotated. According to such a configuration,
The insertion of the one end of the holding member into the recess from the insertion opening becomes smooth, and after the rotation of the connecting clamp, the upper jaw comes into contact with the surface of the holding member, so that friction between the upper jaw and the holding member is generated. A force is generated, and the connecting clamp is more firmly fixed to the holding member.

In the above invention, in a state where the surface of the holding member is in contact with the abutting surface of the upper jaw, the tip of the lower jaw is formed by a claw biting the back surface of the holding member. It is characterized by becoming. That is, since the lower jaw acts as a claw for the holding member, the coupling clamp is more firmly fixed to the holding member in combination with the frictional force between the upper jaw and the holding member.

According to another aspect of the present invention, there is provided a connecting clamp having a different configuration for more reliably exerting the load action of the held member.
As described in above, a claw that bites the surface of the holding member may be provided at the tip of the upper jaw. In the coupling clamp having the rotation space, after the rotation, the upper jaw serves as a contact surface in contact with the holding member surface, and at the same time, the lower jaw tip acts as a claw for the back surface of the holding member. Therefore, if a claw is also provided at the tip of the upper jaw, the occlusal action by the upper jaw and the lower jaw can be more reliably exerted,
The connecting clamp is firmly fixed to the holding member, and the held member can be fixed to the skeleton side without welding via the connecting clamp.

Further, in the above invention, as described in claim 6, the fixing portion is provided on a side surface of the clamp portion and has a mounting surface that can be mounted on the held member.
It may be constituted by a screw hole provided on the mounting surface. In this connection clamp, since the fixing portion is provided on the side surface of the clamp portion, the width of the selection of the mounting surface is widened, and the degree of freedom of the holding form of the held member is widened.

[0014] Further, as another connecting clamp having a different structure for more reliably exerting the action of the load of the held member and efficiently attaching the connecting clamp to the holding member, When the connecting clamp is rotated outward with respect to the holding member about the point where the tip of the lower jaw contacts the back surface of the holding member in the rotation space, an arc bottom corresponding to the locus drawn by the tip of the holding member. And the slide surface and the contact surface. With such a configuration, when inserting the connecting clamp at one end of the holding member, if the slide surface is moved along the back surface of the holding member, the tip of the holding member abuts against the bottom of the arc, and the connecting clamp is moved outward as it is. If it rotates in the direction, the connecting clamp will rotate smoothly downward, and the other surface of the holding member will smoothly contact the contact surface. Therefore, the connecting clamp can be easily attached to the holding member, and the occlusal action by the upper jaw and the lower jaw can be more reliably exerted. The connecting clamp is firmly fixed to the holding member, The member to be held can be fixed to the skeleton side without welding through the through hole.

As described above, the holding member inserted through the insertion opening is gradually tightened to the upper jaw and the lower jaw as the connecting clamp is rotated in the rotation space, and the tip of the upper jaw is When the claw is provided, the tightening pressure of the upper jaw and the lower jaw of the clamp together with the tip of the lower jaw can be increased to the occlusal force. Therefore, in principle, a crimping tool for crimping the back surface of the holding member is unnecessary. However, if a screwing hole for attaching a crimping tool for crimping the back surface of the holding member is provided in the lower jaw as described in claim 8, a crimping tool such as a screw can be provided through the screwing hole. The contact between the contact surface of the upper jaw and the surface of the holding member can be ensured by pressing the one end of the holding member against the back surface.
In addition, since the rotation of the connection clamp in the inward direction with respect to the holding member is restricted, the occlusal force can be further ensured. In particular, when the action of the force due to the weight of the held member cannot be expected, for example, when the held member is light or the gravity of the held member is sufficient, the occlusal force is insufficient due to the fixed position of the held member. It is effective in the case. It is also effective against an external force such as rotating the connecting clamp inward with respect to the holding member.

In the above invention, as set forth in the ninth aspect, the fixing portion includes a mounting surface in which the outer periphery of the clamp portion is divided into a plurality of portions, and a screw hole provided in the mounting surface. By setting the outer periphery of the clamp portion to a plurality of divided mounting surfaces, it is assumed that one end (blade) of the holding member is fixedly extended in a fixed direction such as a horizontal direction so as to correspond to an environment in which the holding member is arranged. Since the mounting surface of the held member can be selected, the degree of freedom of the holding mode can be increased.

In each of the connecting clamps of the above inventions,
Assuming that the widths of the upper and lower jaws are the same, if a force that swings the connecting clamp acts in a direction perpendicular to the direction in which the upper and lower jaws face each other, the upper and lower jaw tightens. There is a possibility that the urging force and the occlusal force cannot sufficiently counter the rocking force. Therefore, as described in claim 10, by setting the width of the lower jaw approximately twice as large as the width of the upper jaw, the point of action of the tightening force or the occlusal force is provided at a position that can oppose the rocking force. did. As a result, the connecting clamp can be securely attached to one end of the holding member extending in the vertical direction, and a general-purpose connecting clamp that is compatible with all extending directions of the holding member one end can be obtained.

Next, a method of mounting a connecting clamp having a rotating space capable of efficiently performing a mounting operation of the connecting clamp to a holding member among the connecting clamps is described in claim 11. First, from the insertion hole of the connecting clamp, slide the connecting clamp into one end of the holding member along the slide side surface, and push the tip of the holding member against the bottom of the arc, then hold the connecting clamp. It is characterized in that it is turned outward with respect to the member. According to this method, since the holding member rotates around the point where the tip of the lower jaw contacts the back surface of the holding member until the holding member contacts the contact surface of the upper jaw, the connecting clamp is very easily attached to the holding member. Can be installed.

Next, the wiring method using the connecting clamp includes a first step of setting a fastener in a screw hole of the fixing portion, and a step of setting the connecting clamp. From the insertion opening, slide the slide clamp into one end of the holding member along the slide surface, abut the tip of the holding member against the bottom of the arc, and rotate the connection clamp outward with respect to the holding member. It is characterized by comprising two steps, a third step of screwing the held member to the fastener, and a fourth step of fixing a cable to the held member. According to the second step, the connecting clamp rotates around the point where the lower jaw and the holding member come into contact with each other until the holding member comes into contact with the contact surface of the upper jaw. Can be easily installed. In addition, wiring work can be performed without welding by the first, third, and fourth steps.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a connecting clamp according to the present invention will be described with reference to the drawings. FIG. 1 is a side view of a connecting clamp (hereinafter, referred to as a first connecting clamp) according to the first embodiment, and FIG. 2 is a front view of the same.

As shown in FIG. 1, the first connecting clamp 3 is connected to one end 10 of an angle material (an angle material is basically used in the embodiment) fixed to the skeleton side as the holding member 1. The receiving recess 30, the clamp portion 34 including the upper jaw 31 and the lower jaw 32 that form the recess 30 and abut on the front and back surfaces 11 and 12 of the one end 10 of the angle member, and fix a cable or the like as the held member 2. And a fixing portion 4 for fixing a supporting member or the like, which is interposed between the angle member or the like and the supporting member or the like, and connects them.

As shown in FIG. 1, the side surface of the connecting clamp 3 is formed in a substantially jaw shape with a concave portion 30, an upper jaw portion 31 and a lower jaw portion 32 corresponding to the "mouth". Each end 31a, 32a of the upper jaw 31 and the lower jaw 32 is an insertion port 37 for receiving one end 10 of the angle material in the recess 30. The height H (see FIG. 2) of the insertion port 37 is an angle. The height is substantially equal to the thickness t of the material. And the upper jaw 3
1 and the front ends 31a, 32a of the lower jaw 32 contact the front and back surfaces 11, 12 of the one end 10 of the angle material, and
1a is located closer to the angle material tip 13 than the lower jaw tip 32a. In relation to these positions, the fixing portion 4 is provided at a position where the load of the held member 2 can be applied to the tightening force of the upper jaw 31 and the lower jaw 32, that is, at a lower portion of the lower jaw 32. The first connecting clamp 3 having such a configuration is arranged so that the upper jaw 31
A force is applied in the right rotation direction R (outside of the angle material) on the drawing centering on each of the distal ends 31a and 32a of the lower jaw 32. Therefore, the tightening force of the upper jaw portion 31 and the lower jaw portion 32 of the clamp portion 34 increases in proportion to the weight of the support member and the cable fixed thereto, so that the support member can be connected via the connecting clamp without welding. Can be fixed to the skeleton side. Further, not only is welding unnecessary, but also one end 10 of the angle material is received in the recess 30 so that the upper jaw 3
1 and the lower jaw 32 only need to be brought into contact with each other, so that the efficiency of the work of attaching the connecting clamp to the angle member 1 can be improved.

As shown in FIG. 2, the width W of the upper jaw 31 and the lower jaw 32 of the first connection clamp 3 is the same, and the width is the outer circumference 34 of the clamp 34.
When a is used as the fixing portion 4, a hole for screwing can be provided, and it is formed to such an extent that a nut for a bolt can be arranged.

Next, a connecting clamp according to a second embodiment (hereinafter, referred to as a second connecting clamp) will be described with reference to FIGS. FIG. 3 shows a second connecting clamp 3.
A is a perspective view of FIG. 4, and FIG.
(A) is a side view of the connecting clamp in a state where the connecting clamp (3A) is inserted into the angle material (before rotation), and (b) is a state from the state shown in (a). The connecting clamp 3A is rotated outward (downward in the drawing, that is, in the direction of the arrow in FIG. 4B) with respect to the angle member 1 so as to be attached to the angle member 1 (after rotation). It is a connection clamp side view.

The feature of the second connecting clamp 3A is as follows.
Before the held member 2 is fixed, a mechanism (hereinafter referred to as an occlusal force applying mechanism) for previously engaging the upper jaw 31 and the lower jaw 32 with the angle member 1 is provided, and the action of the load of the held member 2 is reliably exhibited. It is in the configuration to make it. That is, as shown in FIGS. 3 and 4A, the concave portion 30 of the second coupling clamp 3A is provided with the upper jaw end 31a and the lower jaw end 32a facing each other.
During the interval H1, the insertion opening 37 corresponding to the plate thickness t of the one end 10 of the angle material is formed. Specifically, the interval H1 and the plate thickness t are
It suffices that the relationship of H1 ≧ t is satisfied, but it is desirable that the thickness H and the interval H1 be closer to each other.

The concave portion 3 of the second connecting clamp 3A
0 is the insertion slot 3 as shown in FIG. 3 and FIG.
7, the front and back surfaces 11 of the angle material 1 inserted through
The upper jaw portion 31 and the lower jaw portion 32 are provided with a turning space 38 in which the clamp portion 34 turns outwardly with respect to the angle material 1 so that the upper portion 12 and the lower jaw portion 32 can be tightened. As shown in FIG. 4A, the rotation space 38 has a predetermined angle α (hereinafter, referred to as a reference angle L) with the surface 11 of the angle material 1 as a reference plane L for rotation.
(The angle is referred to as a rotation angle α).

In the second connecting clamp 3A having such a structure, the connecting clamp 3A is rotated with respect to the angle member 1 fixed to the skeleton side, and as the angle becomes deeper, the upper jaw tip 31a and the lower jaw 31a. The interval H1 between the tips 32a becomes relatively small. 4B, the front and back surfaces 11 and 12 of the angle material are tightened by the upper jaw 31 and the lower jaw 32, as shown in FIG.
It is an occlusal force applying mechanism that can occlude. At the same time, the lower jaw tip 32a gradually moves away from the angle material tip 13, while the upper jaw tip 31a gradually approaches the angle material tip 13, which is similar to the first connection clamp 3 described above. It has a configuration.

As shown in FIG. 4 (a), the fixing portion 4 is provided on the bottom portion 40 of the lower jaw portion 32, and has a mounting surface inclined obliquely upward at an angle α 'substantially equal to the rotation angle α. 4
1 and a screw hole 42. The fixing portion 4 is synchronized with the rotation of the connecting clamp 3A, and is positioned parallel to the surface 11 of the angle member 1 after the rotation, as shown in FIG. Therefore, the load of the held member 2 (not shown) fixed to the fixing portion 4 acts in the vertical direction, and the upper jaw portion 31 and the lower jaw portion 32 of the clamp portion 34 are proportional to the weight of the held member 2. The tightening force and the occlusal force can be increased.

As shown in FIGS. 3 and 4A, the side surface of the concave portion of the lower jaw 32 is formed parallel to the reference plane L for rotation, and one end of the angle material is inserted through the insertion opening 37. 1
When a 0 is inserted, the slide surface 32c is slid to the back surface 12 of the angle material 1. Therefore,
The insertion of the angle material from the insertion opening 37 into the recess 30 becomes smooth.

The inclined surface 5 of the upper jaw 31 is also shown in FIG.
As shown in FIG. 4 (a), the connecting member 3A is formed flat, and when the coupling clamp 3A is turned, the contact surface 31d is in contact with the surface 11 of the angle member 1.
As a result, after the rotation of the connecting clamp 3A, the inclined surface 5 comes into contact with the surface 11 of the angle member 1, so that a frictional force is generated between the upper jaw 31 and the angle member 1, and the connecting clamp 3A 1 firmly fixed.

Since the slide surface 32c is formed flat with respect to the rotation reference surface L, the connecting clamp 3A
, The tip of the slide surface 32 c, that is, the lower jaw tip 32 a forms an acute angle with the back surface 12 of the angle material 1. Since the distance H1 between the upper jaw tip 31a and the lower jaw tip 32a becomes relatively small in proportion to the rotation, the lower jaw tip 32a is attached to the back surface 1 of the angle material 1.
Dig into 2. Therefore, the tip 32a of the lower jaw 32
Can be configured as a claw that bites the back surface 12 of the angle material, and as a result, the coupling clamp 3A is coupled with the frictional force between the upper jaw contact surface 31d and the angle material 1 so that the connection clamp 3A Firmly fixed to

The width W of the upper jaw 31 and the lower jaw 32 of the second connecting clamp 3A is the same as that of the first connecting clamp 3 described above, and as shown in FIG. The clamp portion 34 is formed in a substantially U-shaped groove with its outer periphery 34a as a bottom side. And the outer circumference 34 of the clamp portion
a is the fixing portion 4, a screw hole 4 is formed in the bottom of the groove.
2 can be provided, and a nut for a bolt can be arranged. Such a configuration is the same for the third and fourth coupling clamps described in detail below.

Next, a connecting clamp according to a third embodiment (hereinafter, referred to as a third connecting clamp) will be described with reference to FIGS. FIG. 5 shows a third connection clamp 3.
B is a perspective view, and FIG. 6 shows an attachment procedure when attaching the third connection clamp 3B to the angle material.
(A) is a side view of the connecting clamp 3B before rotation, (b)
Is a side view of the connecting clamp 3B after rotation.

The features of the third connecting clamp 3B are as follows.
The configuration is such that the occlusal force applying mechanism is improved so that the action of the load on the held member 2 is more reliably exerted. That is, a claw 31c that bites the angle material surface 11 is provided on the upper jaw end 31a of the third coupling clamp 3B. In the third connecting clamp 3B, the second connecting clamp 3
Similarly to A, after the rotation of the connecting clamp 3B, the contact surface 31d of the upper jaw 31 comes into contact with the angle material surface 11. At the same time, as shown in FIG.
The second tip 32 a functions as a claw for the angle material back surface 12. Thus, in the third coupling clamp 3B, the claw action of the upper jaw 31 and the lower jaw 32 with respect to the angle member 1 is further ensured by providing the nail 31c at the upper jaw tip 31a.

In the third connection clamp 3B, unlike the second connection clamp 3A, the fixing portion 4 is provided on the side surface 34b of the clamp portion 34. That is,
As shown in FIGS. 5 and 6, the screw holes 42 forming the fixing portion 4 are provided at a branch portion where the upper jaw 31 and the lower jaw 32 branch. If a screw hole 42 is provided at this position, in the horizontally extending angle material 1, the contact points of the upper jaw part 31 and the lower jaw part 32 with respect to the front and back surfaces 11 and 12 of the angle material one end 10 and the held member 2 The distance to the line of action of the load force can be maximized. Therefore, the upper jaw 31
In addition, the tightening force or the occlusal force of the lower jaw 32 can be increased, and the held member 2 can be fixed to the skeleton side without welding through the connecting clamp. Further, the degree of freedom of the holding form of the held member 2 is increased, and it is possible to adapt to the arrangement environment of the holding member 1 such as an angle material.

The screw holes 42 are not limited to the places shown in the drawings, but may be the clamp side 34b of the upper jaw 31 or the clamp side 34b of the lower jaw 32.
May be. Further, the outer periphery 34a of the clamp portion 34
A screw hole 42 may be provided in the hole. FIG. 6B also shows the third connection clamp 3B in addition to the first mounting surface 41a.
As shown in (2), the second mounting surface 41b is provided, and the degree of freedom of the holding form of the held member 2 is increased.

The configuration other than the above is the same as that of the second connecting clamp 3A. Therefore, the third connecting clamp 3B has the same operation and effect as the second connecting clamp 3A.

Next, a connecting clamp according to a fourth embodiment (hereinafter, referred to as a fourth connecting clamp) is shown in FIGS.
It will be described based on. FIG. 7 shows a fourth connection clamp 3C.
FIG. 8 is a central vertical sectional view of the connecting clamp 3C.

The feature of the fourth connecting clamp 3C is as follows.
The configuration is such that the action of the load of the held member 2 is more reliably exerted, and the efficiency of the mounting work of the occlusal force applying mechanism is improved. That is, when the connecting clamp 3C is rotated outward with respect to the angle member 1 around the point P at which the tip 32a of the lower jaw portion 32 contacts the back surface 12 of the angle member, the tip 13 of the angle member 1 becomes An arc bottom 39 corresponding to the locus to be drawn is provided on the inner surface of the recess. The start end of the arc bottom 39 is continuous with the end of the slide surface 32c, and the end of the arc bottom 39 is continuous with the end of the contact surface 31d. And the contact surface 31d, and the side surface shape is fan-shaped.

In the fourth connection clamp 3C, when the connection clamp 3C is inserted into one end 10 of the angle member 1,
By moving the slide surface 32c of the connection clamp 3C along the back surface 12 of the angle material to abut the front end 13 of the angle material against the bottom 39 of the arc and rotating the connection clamp 3C downward in the drawing as it is, Material tip 1
3 is guided by the arcuate bottom portion 39, the connecting clamp 3C rotates, and the surface 11 of the angle member 1 smoothly abuts against the abutting surface 31d. Therefore, the connecting clamp 3C can be easily attached to the angle member 1, and the efficiency of attaching work of the occlusal force applying mechanism can be improved.

In the fourth connecting clamp 3C,
A crimping hole 43 for attaching a crimping tool for crimping the holding member back surface 12 is provided in the lower jaw 32. As shown in FIGS. 7 and 8, the crimping hole 43 is located immediately below the circular arc bottom 39 so that the center axis thereof is orthogonal to the contact surface 31 d and the angle member 1 after the rotation of the coupling clamp 3 </ b> C. Third provided
On the mounting surface 41c.

The reason for providing the pressure bonding hole 43 is as follows. As shown in FIG. 8, the angle member 1 is securely occluded by the claw 31c at the tip of the upper jaw and the tip 32a of the lower jaw. However, when the action of force due to the weight of the held member 2 cannot be expected, for example, when the held member 2 is light, or even when the weight of the held member 2 is sufficient, the weight of the held member 2 depends on the fixing position of the held member 2. If the action of the angle member 1 cannot be expected, the hardness of the angle member 1 may be high and sufficient occlusal force may not be expected. Therefore, in order to make it possible to attach a crimping tool and to make the occlusal force of the connection clamp 3C more reliable, the crimping hole 43 is provided. Also, angle material 1
, The rotation in the inward direction (upward direction U shown in FIG. 8) can be restricted, and the lateral displacement can also be restricted. It is to be noted that if threads are cut in advance in the crimping holes 43, the work efficiency is increased. In addition, the pressure bonding hole 43 can function as the fixing portion 4.

In the fourth connection clamp 3C, the outer periphery 34a of the clamp portion is divided into a plurality of portions to form mounting surfaces. This fixing part 4
As shown in FIG. 8, a first mounting surface 41 a provided parallel to the contact surface 31 d and the angle member 1 after the rotation of the connecting clamp 3 </ b> C and provided on the bottom 40 of the lower jaw 32. Similarly, a second mounting surface 41b provided in parallel with the contact surface 31d and provided above the upper jaw 31, a third mounting surface 41d provided at a position inclined with respect to the contact surface 31d, and a contact. Fourth mounting surface 4 provided at a position orthogonal to surface 31d
1e. Since the mounting surface can be selected from each of the mounting surfaces 41a to 41e, including the third mounting surface 41c, in accordance with the environment in which the holding member 1 such as an angle member is arranged, the degree of freedom of the holding form is increased. For example, as shown in FIG. 14, which will be described later, with respect to an angle material that is fixed in the horizontal direction with respect to the frame and whose blade extends in the horizontal direction,
The support member of the held member 2 can be fixed to the mounting surface 41b, and can also be fixed to the first mounting surface 41a. Further, first and fifth mounting surfaces 41a, 41 are fixed to a channel steel (C channel) which is fixed to the skeleton in an upwardly open U-shape in the horizontal direction and whose blade extends in the vertical direction.
e can be selected. Further, a crimping tool is attached to the crimping hole 43 with respect to the angle material having the blade extending in the horizontal direction and the blade extending in the vertical direction, so that the occlusal force of the connecting clamp 3C is further improved. After being secure, the second mounting surface 41b can also be selected.

The configuration other than the above is the same as that of the second and third connection clamps 3A and 3B. Therefore, the fourth connection clamp 3C is provided with the second and third connection clamps 3C.
The same operation and effects as those of A and 3B are obtained.

Next, a connecting clamp according to a fifth embodiment (hereinafter referred to as a fifth connecting clamp) will be described with reference to FIG. FIG. 9 is a perspective view of the fifth connection clamp 3C '.

The main feature of the fifth connection clamp 3C 'is that the fixing portion 4 provided on the fourth connection clamp 3C is provided.
Fastener setting space S to make it easier to set the fastener
Is provided in the clamp part 34. The fastener setting space S has a width S2 corresponding to a fastener for the screw hole 42 of the first mounting surface 41a, for example, a head and neck length (hereinafter, referred to as a bolt length). The third mounting surface 41d has a width S3 corresponding to a bolt length of a bolt fixed to the screw hole 42 of the fourth mounting surface 41e and a width S1 corresponding to a bolt length of a bolt fixed to the screw hole 42 of the fourth mounting surface 41e. And it is formed so as to penetrate between the clamp portion side surfaces 34b. With the fastener setting space S, the setting operation of the fastener with respect to the fixing portion 4 becomes extremely easy.

Since the configuration other than the above is the same as that of the fourth connection clamp 3C, the fifth connection clamp is 3C
'Has the same effect as the fourth coupling clamp 3C.

Next, a connecting clamp (referred to as a sixth connecting clamp) according to the sixth embodiment will be described with reference to FIGS.
It will be described based on. FIG. 10 shows a sixth coupling clamp 3
D is a perspective view, FIG. 11 is a side view of the connecting clamp, and FIG.
2 is a front view of a state in which a sixth connecting clamp 3D is fixed to the angle member 1 extending in the vertical direction.

The main difference between the sixth connecting clamp 3D and each of the connecting clamps described above is that the width 2W of the lower jaw 32 is approximately twice the width W of the upper jaw 31. In each of the first to fifth coupling clamps, since the upper jaw 31 and the lower jaw 32 have substantially the same width, the upper jaw 31 and the lower jaw 3
When an external force that swings the connecting clamp acts in a direction (see the Y direction shown in FIG. 12) orthogonal to the direction in which the two oppose each other, the occlusal force may not sufficiently counter the swinging force. Therefore, the width of the lower jaw 32 is set to approximately 2 times the width of the upper jaw 31.
As shown in FIG. 12, the occlusal points with the angle material 1 are set to K1 and K2 so as to be able to resist the rightward swinging force as shown in FIG.
On the other hand, the occlusal points with the angle member 1 are provided as K3 and K4 so as to oppose the leftward swinging power. as a result,
The connecting clamp 3D can be securely attached to the one end 10 of the angle member 1 extending in the vertical direction, and can be used in almost all arrangement directions of the angle member 1. Can be

The fixing portion 4 provided on the clamp portion side surface 34b of the sixth connecting clamp 3D is provided so as to protrude from the clamp portion both side surfaces 34b, 34b. Each of the fixing portions 4 is formed in a substantially U-shape. The screw holes 42 are formed in the upper and lower horizontal sides, and the screw holes 42 are formed in the vertical sides. I have. According to the fixing portion 4 having such a configuration, even after the connecting clamp 3D is engaged with the angle member 1, the work of setting the screw for fixing the held member in each hole 42 becomes easy.

The hole indicated by "43" is a crimping hole for mounting a crimping tool for crimping the back surface 12 of the angle material, and has the same effect as the crimping hole 43 of the fourth coupling clamp 3C. There is something to play. Then, this crimping hole 43
Is provided with a thick mounting surface 41 at a position directly below the circular arc bottom portion 39, and is formed by forming a thread therethrough. The configuration other than the above is the same as that of the above-described fourth connection clamp 3C. Therefore, the sixth connection clamp 3D has the same operation and effect as the fourth connection clamp 3C.

Next, referring to FIGS. 13 and 14, the fourth connecting clamp 3C is used to connect the fourth connecting clamp 3C.
The method of mounting will be described. FIG. 13 is a side view of the connection clamp 3C before rotation, and FIG. 14 is a side view of the connection clamp 3C after rotation. First, as shown in FIG. 13, the slide member 32 is slid into the one end 10 of the angle member 1 along the slide surface 32c from the insertion opening 37 of the connecting clamp 3C, and the tip end 13 of the angle member 1 is brought into contact with the circular arc bottom 39. Next, the connecting clamp 3C is rotated outward with respect to the angle member 1, that is, downward in FIG. According to such an attaching method, the angle member 1 is guided to the arc bottom 39 with the point P at which the lower jaw portion 32a contacts the angle member back surface 12 as the center point, and the angle member 1 is connected to the upper jaw portion 3.
Since it rotates until it comes into contact with the first contact surface 31d, it can be mounted very easily. In addition, clamp 3C for connection
When turning in the outward direction with respect to the angle member 1, a turning force may be applied by a gavel or the like. Also,
A tip of a driver or the like may be inserted into the fourth mounting surface 41d, and the driver may be turned outward. afterwards,
If a screw is screwed into the crimping hole 43 and the back surface 12 of the angle material 1 is crimped, the bite can be more reliably engaged. In FIGS. 13 and 14, what is indicated by “6” is a nut for a crimping tool that is fixed to the inner groove of the lower jaw 32 in advance.

Next, a wiring method using the fourth coupling clamp 3C will be described with reference to FIGS. 13, 14, and 15. FIG. FIG. 15 is a side view of a state where a support member as the held member 2 is fixed to the coupling clamp 3C. First, a fastener is set in the screw hole 42 of the fixing portion 4. This set work is performed by connecting clamp 3C
Can be set at the stage of mass production, but may be set one by one at the construction site because it is necessary to match the extending direction of the blade of the angle material 1 fixed to the skeleton side of the construction site. In this embodiment, as shown in FIG. 15, the blade of the angle member 1 extends in the horizontal direction, and it is assumed that the support member is mounted on the second mounting surface 41b. Set bolts from inside.

Next, as shown in FIGS. 13 and 14, the slide side surface 32a is inserted through the insertion opening 37 of the connecting clamp 3C.
The connecting clamp 3C is slid into the one end 10 of the angle material along the line, and the tip 13 of the angle material 1 is
9, and the connecting clamp 3C is rotated outward with respect to the angle member 1. By the second step, the connection clamp 3C is connected to the angle material 1 as described above.
Can be mounted very easily. Then, if necessary, the back surface of the angle material 1 is pressure-bonded with a fastener through the pressure-bonding hole 43.

The side surfaces 34 of the clamp portion 34 like the third connecting clamp 3B and the sixth connecting clamp 3D.
If the fastener can be set after the connecting clamp is fixed to the angle material 1 such as when the fixing portion 4 is provided in b, the fastener may be set after the second step.

Next, the support member 2 is screwed to a bolt set on the second mounting surface 41b. Finally, by fixing the cable 8 to the support member 2, the cable 8 is wired in parallel with the angle member 1 (vertically in the drawing). Thus, in the first, third, and fourth steps, wiring work can be performed without welding. If the "faster clamp (trade name) 9" previously developed by the applicant is used for fixing the cable 8, the working time can be reduced.

Next, an example of using the connecting clamp 3C for purposes other than wiring work will be described with reference to FIG. FIG. 16 shows a case where two connecting clamps 3C, 3C are used for the H-section steel 7 as the holding member 1, and for example, a lighting fixture mounting piece 7A is fixed to the fixing portion 4. According to this mounting method, since each of the connecting clamps 3C, 3C can resist external force acting in the inward direction of the H-shaped steel 7, a lighting fixture or the like can be mounted firmly.

Each of the connecting clamps is manufactured by casting an alloy, for example, an aluminum alloy for casting or stainless steel, and hardening the casting as it is or by applying a heat treatment such as quenching. "Hardness" is preferably about "HRC 35 to 40".

In each of the above embodiments, an angle material having a plate thickness of 5 mm is used as the holding member 1.
In addition, when the plate thickness is different such as 3 mm or 10 mm in thickness, a corresponding connection clamp is used.

[0060]

Next, an embodiment of a fourth connecting clamp 3C will be described with reference to FIG. In this embodiment, an L-shaped angle member of 50 × 50 × 5 (plate thickness t, unit millimeter, the same applies hereinafter) is assumed as the holding member 1. In this case, the width w1 of the clamp portion 34 is 14, the length 11 of the slide surface of the lower jaw portion 32 is 20, and the radius r of the arc bottom portion 39 is 2
0, the width w2 of the nail 31c of the upper jaw 31 is 3, the rotation angle α is 22.5 degrees, the contact surface width w3 of the upper jaw 31 is 14.9, and the tip interval between the upper jaw 31 and the lower jaw 32 is 5 , First mounting surface 4
The width w4 of 1a is 19, and the width w5 of the second mounting surface 41b is 1
8.3, the width w6 of the third mounting surface 41c is 14.6, the width w7 of the fourth mounting surface 41d is 24.5, and the fifth mounting surface 4
The width w8 of 1e is 22.6.

When the connecting clamp of this size is turned outwardly to the above-mentioned turning angle of 22.5 degrees with respect to the L-shaped angle member, the lower jaw tip 32a and the pawl 3 of the contact surface 31d are rotated.

According to the first aspect of the present invention, the tightening force of the upper jaw and the lower jaw of the clamp increases in proportion to the weight of the held member. The member to be held can be fixed to the skeleton side via the. In addition, it is only necessary to receive one end of the holding member in the concave portion and make the upper and lower jaws come into contact with each other, so that welding is not required, and the efficiency of the work of attaching the connecting clamp to the holding member can be improved.

According to the second aspect of the present invention, since the insertion opening corresponds to the thickness of one end of the holding member and is formed between the opposed upper jaw and lower jaw which are opposed to each other,
The holding member inserted through the insertion opening, the upper jaw and the lower jaw gradually tighten the front and back surfaces of the holding member as the connection clamp is rotated in the rotation space outward of the holding member. It is also possible to do. In addition, since the fixing portion is provided at the bottom of the lower jaw, the distance between the tip of each of the upper jaw and the lower jaw with respect to the front and back surfaces of the holding member and the line of action of the load force of the held member can be maintained. The tightening force and the occlusal force of the upper and lower jaws of the clamp part increase in proportion to the weight of the member. Therefore, the upper jaw and the lower jaw of the clamp portion securely tighten the holding member, and the held member can be fixed to the skeleton side without welding via the connecting clamp. This means that screwing such as a screw for supporting the fixed state is not necessary in principle.

According to the third aspect of the present invention, the insertion of the one end of the holding member into the recess through the insertion opening becomes smooth, and after the rotation of the connecting clamp, the upper jaw is moved to the surface of the holding member. , A frictional force is generated between the upper jaw and the holding member, and the connecting clamp is more firmly fixed to the holding member.

According to the fourth aspect of the present invention, since the lower jaw acts as a claw for the holding member, the coupling clamp is more firmly held together with the frictional force between the upper jaw and the holding member. It is fixed to the member.

In the connection clamp having the above-mentioned rotating space, the upper jaw serves as a contact surface in contact with the surface of the holding member after the rotation, and the tip of the lower jaw acts as a claw for the holding member. Therefore, according to the invention described in claim 5, a claw is also provided at the tip of the upper jaw,
The occlusal action of the upper and lower jaws can be exerted, and the upper and lower jaws of the clamp part can securely tighten the holding member, and the held member can be connected to the body without welding via the connecting clamp. Can be fixed to the side.

In the connecting clamp according to the sixth aspect, the fixing portion is also provided on the side surface of the clamp portion, so that the width of selection of the mounting surface is widened and the degree of freedom of the holding form of the held member is widened.

According to the seventh aspect of the invention, when the connecting clamp is inserted into one end of the holding member, the slide surface is moved along the back surface of the holding member so that the tip of the holding member abuts against the bottom of the arc. At the same time, if the connecting clamp is rotated downward, the connecting clamp smoothly rotates downward, and the other surface of the holding member smoothly abuts against the abutting surface. Therefore, the connecting clamp can be easily attached to the holding member, and the occlusal action by the upper jaw and the lower jaw can be more reliably exerted. The connecting clamp is firmly fixed to the holding member, The member to be held can be fixed to the skeleton side without welding through the through hole.

According to the eighth aspect of the present invention, a crimping tool such as a screw is crimped to the back surface of one end of the holding member through the screwing hole, so that the contact surface between the upper jaw and the surface of the holding member is pressed. The contact can be ensured, and the upward rotation of the connecting clamp is restricted, so that the occlusal force can be further ensured. In particular, when the action of the force due to the weight of the held member cannot be expected, for example, when the held member is light or the gravity of the held member is sufficient, the occlusal force is insufficient due to the fixed position of the held member. It is effective in the case. It is also effective against an external force such as rotating the connecting clamp inward with respect to the holding member.

According to the connecting clamp of the ninth aspect, by forming the outer periphery of the clamp portion into a plurality of mounting surfaces, one end (blade) of the holding member is fixedly extended in a fixed direction such as a horizontal direction. Since the mounting surface of the held member can be selected according to the environment in which the holding member is arranged, the degree of freedom of the holding form can be increased.

According to the connecting clamp of the tenth aspect, by setting the width of the lower jaw approximately twice as large as the width of the upper jaw, the point of action of the tightening force or the occlusal force can be reduced between the upper jaw and the lower jaw. It can be provided at a position that can oppose a swinging force acting in a direction orthogonal to the direction. Therefore, the connecting clamp can be securely attached to one end of the holding member extending in the vertical direction, and a general-purpose connecting clamp that is compatible with all extending directions of the holding member one end can be provided.

According to the eleventh aspect of the present invention, since the holding member rotates around the point where the tip of the lower jaw contacts the back surface of the holding member until the holding member contacts the contact surface of the upper jaw, it is extremely simple. The connecting clamp can be attached to the holding member.

According to the twelfth aspect of the present invention, in the second step, the connecting clamp is turned around the point where the lower jaw and the holding member come into contact with each other until the holding member contacts the contact surface of the upper jaw. Due to the rotation, the connecting clamp can be attached to the holding member very easily. In addition, wiring work can be performed without welding by the first, third, and fourth steps.
