Abstract
A clamp for clamping a scaffolding tube (2) to a structural member (5) consists of a U-shaped member (1) adapted to receive the scaffolding tube (2) with the limbs of the member (1) on each side of the tube, each limb of the member (1) having a slot (3) shaped to receive and conform to a part (4) of the structural member (5). The clamp has an eyebolt (6) for urging the tube (2) into contact with the structural member to hold it in position in the slot (3). <IMAGE>
Description
of the slot 3 is inclined at an angle 8 (for example 50) to suit the inclination of the surface of the web 4. However, various other profiles for the slot may be used to co-operate with the surfaces of various structural members, any misalignment being accommodated by rotation of the clamp about the point of contact of the eyebolt 6 with the tube 2 until the upper margin of the slot 3 is the best fit to the surface of the structural member which it is engaging.
Although the invention has been described with reference to the clamping of a beam or girder 5, it will be appreciated that the clamp may equally well be used to clamp a scaffolding tube to a flat plate, composed for example of steel, aluminium or wood, in which case the angle 8 may be made 00.
Claims: (filed on 12 Jan 1983)
1. A clamp for clamping a scaffolding tube to a structural tube to a structural member which consists of a U-shaped member adapted to receive the scaffolding tube with the limbs of the member on each side of the tube, each limb of the member having a slot to receive a part of the structural member, and means for urging the tube into contact with the structural member to hold it in position in the slot.
2. A clamp as claimed in claim 1, wherein the slots in the limbs of the U-shaped member are arranged to receive part of the structural member extending at right angles to the scaffolding tube.
3. A clamp as claimed in claim 1 or 2, wherein the means for urging the tube consists of means for applying a force between the tube and the part of the U-shaped member between the two limbs.
4. A clamp as claimed in claim 3, wherein the means for urging the tube consists of a bolt in a threaded hole in the U-shaped member, the end of the bolt being arranged to contact the tube.
5. A clamp as claimed in any one of claims 1 to 4, wherein the slots have profiles shaped to cooperate with the surfaces of the structural member.
6. A clamp as claimed in claim 5, wherein the structural member is a beam or girder having a web and the margin of the slot remote from the tube is inclined to match the inclination of the surface of the web.
7. A clamp for clamping a scaffolding tube to a structural member, substantially as described with reference to the accompanying drawings.
SPECIFICATION
Clamp
This invention relates to a clamp for the purpose of clamping a scaffolding tube to another member.
Various forms of clamps have been devised over the years for the purpose of clamping scaffolding tubes to each other, for clamping to each other structural members, such as flat plate or metal or timber beams or beams or girders having webs, and for clamping a scaffolding tube to a structural member, but those for the last purpose have either been relatively complicated or have proved difficult to use.
It is an object of the present invention to provide an improved clamp for this last purpose which overcomes these disadvantages.
The present invention consists in a clamp for clamping a scaffolding tube to a structural member which consists of a U-shaped member adapted to receive the scaffolding tube with the limbs of the member on each side of the tube, each limb of the member having a slot to receive a part of the structural member, and means for urging the tube into contact with the structural member to hold them in position in the slot.
In the accompanying drawings: Figure 1 is a side view of one form of clamp according to the present invention;
Figure 2 is an end view of Figure 1; and
Figure 3 is a general view having two such clamps in use.
In carrying the invention into effect according to one convenient mode by way of example,
Figures 1 and 2 show a clamp which consists of a generally U-shaped member 1 dimensioned to receive a scaffolding tube 2. Each limb of the Ushaped member is provided with a slot 3 for receiving the web 4 of a beam or girder 5 engaging the scaffolding tube 2 at right angles to it.
The clamp carries an eye bolt 6 in a threaded hole in the U-shaped member 1 which also has a relief hole 7 to facilitate manufacture.
Clamping is achieved by tightening bolt 6 to urge the scaffolding tube 2 against the web 4 which in turn is urged against the upper part of slot 3.
As shown in Figure 3, for a beam or girder 5 having two webs 4, two clamps are applied to the one scaffolding tube 2.
As will be seen from Figure 1 , the upper margin

Claims (7)
1. A clamp for clamping a scaffolding tube to a structural tube to a structural member which consists of a U-shaped member adapted to receive the scaffolding tube with the limbs of the member on each side of the tube, each limb of the member having a slot to receive a part of the structural member, and means for urging the tube into contact with the structural member to hold it in position in the slot.
2. A clamp as claimed in claim 1, wherein the slots in the limbs of the U-shaped member are arranged to receive part of the structural member extending at right angles to the scaffolding tube.
3. A clamp as claimed in claim 1 or 2, wherein the means for urging the tube consists of means for applying a force between the tube and the part of the U-shaped member between the two limbs.
4. A clamp as claimed in claim 3, wherein the means for urging the tube consists of a bolt in a threaded hole in the U-shaped member, the end of the bolt being arranged to contact the tube.
5. A clamp as claimed in any one of claims 1 to 4, wherein the slots have profiles shaped to cooperate with the surfaces of the structural member.
6. A clamp as claimed in claim 5, wherein the structural member is a beam or girder having a web and the margin of the slot remote from the tube is inclined to match the inclination of the surface of the web.
7. A clamp for clamping a scaffolding tube to a structural member, substantially as described with reference to the accompanying drawings.
