Abstract

The prop connecting ring has an insertion fastener (80) which is a wedge bar inserted into the detention holes of the left and right half ring bodies (40,50) for latching the front ends of the half ring bodies with each other. When the connecting ring is fitted on a prop, the two clamping faces of the half ring bodies and the abutting face serve to clamp and bind the prop. Each of the half ring bodies has insertion holes (42,52) of predetermined number. The rear ends of the half ring bodies are pivotally connected with each other, such that the half ring bodies are pivotally rotated about the pivot sections for opening and closing operation. The clamping faces of the two half bodies are arranged opposite each other for clamping the prop.

Description

The present invention relates generally to a component in the construction field, and is particularly concerned with a column connecting ring which is put on a column is inserted and connected to it in order to support each other in the transverse direction connect. Such a column connecting ring can be attached to a column in any way or the required height.

In Fig. 1, a conventional prop 10 is shown as used in construction. This support 10 has an elongated tubular body 11 on which a plurality of ring bodies 12 is fixedly attached at equal intervals. The upper and lower ends of the tubular body 11 are each provided with an adjustment seat 13 . The extension length of each adjustment seat 13 can be adjusted. Each ring body 12 is provided with a plurality of through openings 14 .

In use, as shown in FIG. 2, the supports 10 are placed upright. Some connecting elements 15 are connected to these through openings 14 of the ring body 12 in order to connect two adjacent supports 10 to one another in the transverse direction. Accordingly, a number of supports can be connected symmetrically to one another to form a framework, such as a scaffold, to support formwork boards.

In the event that the subsurface is not even or even at a construction site, and a lowering of the floor exceeds the maximum extension length of the adjustment seats 13 , the annular bodies 12 of adjacent supports 10 will be arranged at different heights, as in the Fig. 2 is shown. The distance between the supports is fixed, so that the connecting elements 15 must be adjustable in length in order to connect the supports to one another. Such adjustable fasteners are very expensive. In addition, it is necessary to set one connecting element after the other. Such an operation is tedious. In the event that the connecting elements 15 have a different length and the ring bodies 12 are positioned at different heights, non-uniformly distributed forces occur on the frame. This causes problems with regard to security. In addition, the support 10 is provided with a plurality of ring bodies 12 in order to allow a connection by means of the connecting elements at different heights. If the supports are connected to one another in the transverse direction, however, not all ring bodies 12 are used. Therefore, many ring bodies are wasted and the costs are increased.

In FIG. 3, another kind is shown of steel prop 19 can be supported with the form boards. The inner tube 191 of such a support 19 can be inserted into the outer tube 192 in order to adjust the length towards a larger extension length. However, such a support is not equipped with any ring bodies, so that it can only be used in the upright state, and it is impossible to connect adjacent supports in the transverse direction. For this reason, these supports cannot be connected to one another to form a symmetrical framework or framework.

A connecting ring has recently been developed, which is shown in FIG. 4. The water connecting ring 20 has a semi-circular body 22 and a straight lever body 24 which is pivotally connected to the semi-circular body 22 at one end, wherein the semi-circular body 22 can be seen, opened or closed relative to the lever body 24 . A wedge-shaped rod 26 is inserted through a free end of the semicircular body 22 . In use, as shown in FIG. 5, the free end of the semicircular body 22 is inserted through the other end of the lever body 24 . Then the connecting ring 20 is attached around the support 28 . Then the (connecting) rod 26 is moved down to fix the semicircular body 22 and the lever body 24 to the support 28 . Accordingly, the connec tion elements 29 can be connected to the through openings 23 of the semicircular body 22 to connect the support 28 in the transverse direction with an adjacent support.

However, such a connecting ring 20 has some disadvantages, such as: first of all, as shown in FIG. 5, the sections A and B of the connecting ring are adjacent to the support 28 . The contact area is limited, so that the strength of the connection is not high and the connecting ring cannot absorb larger forces if these would occur.

In addition, only one half, in FIG. 5 the left half of the connecting ring, is provided with the through openings 23 in order to establish a connection with the connecting element 29 . The other side of the support cannot be connected to another support in the transverse direction. Therefore, only four supports 28 can be connected to each other in use in such a way that a rectangular framework is formed, while it is impossible to arrange and connect several supports systematically and in the form of a scaffold. In addition, the pivotable ends of the semicircular body 22 and the lever body 24 tend to loosen, so that these two components 22 and 24 tend to swing up and down due to the gap. As a result, the connection strength or strength of this support is moderate.

It is therefore an object of the present invention to provide a column connecting ring to create, which can be freely attached to the support at a desired height can. Therefore, the ring bodies of two adjacent supports can be on the same  Height can be arranged to connect these two supports easier.

It is an object of the present invention to provide such a column connecting ring to further develop such that they are no longer welded to the support does not have to weld several rings to the support at equal intervals need so that the number of connecting rings can be reduced.

It is another object of the present invention to provide such a column ver To create a binding ring, the steel supports can be connected to each other in the transverse direction makes.

Another object of the present invention is to provide such a column ver to create a binding ring that has better clamping properties and higher Allows connecting forces.

Finally, it is an object of the present invention to provide such a column joint to create an extension ring that differentiated a connection of several supports All directions are allowed to build a systematic framework.

This systematically structured scaffolding is also intended to provide an improved support have strength.

In order to achieve the above-mentioned object, the invention has the features described in claim 1 specified features. Advantageous refinements of this are broad ren claims specified.

Referring to FIGS. 6 and 7, there is shown a preferred embodiment of the present invention, said support River binding ring 30 has a left half body 40 and right half body 50 which are pivotally connected at one end to each other. The other ends of the two half-bodies are connected to one another in an overlapping manner, namely by a plug-in attachment 80 .

The left half body 40 is formed out substantially semicircular as a plate body, with some insertion openings 42nd The inner surface of the left half body 40 is designed as a semi-circular clamping surface 44 . The upper and lower edges of the clamping surface 44 are each provided with lip portions 45 protruding outwards. Therefore, the clamping surface 44 has a thickness that is thicker than the wall thickness of the left half body 40 so as to enlarge the contact area. In addition, the front end of the left half body 40 is provided with an insertion opening 46 and the rear end thereof is provided with a pivot opening 41 .

The right half body 50 is also essentially formed as a semicircular plate which is essentially symmetrical to the left half body 40 . The body of the right half body 50 is provided with a plurality of insertion openings 52 . The inner surface of the right half body 50 is a semicircular clamping surface 54 . The upper and lower edges of the clamping surface 54 are each provided with an outwardly projecting arcuate lip section 55 . The top of the front end of the right half body 50 is provided with a projection 56 which extends in the direction of the left half body 40 . The projection 56 is provided at a height which is higher than the body of the right half body. The projection has an upper insertion opening 57 . A clamping plate 58 is fixed below the front end of the right half body 40 and positioned at a height which is lower than the body of the right half body. This clamping plate 58 is positioned below the projection 56 and spaced there by a certain distance in order to define an insertion space 60 . In the lower edge of the clamping plate 58 is provided with an arcuate contact surface 62 . This contact surface 62 and the clamping surface 54 are provided with the same radius of curvature as shown in FIG. 10. The clamping plate 58 is provided with a lower insertion opening 64 which is aligned with the upper insertion opening 57 of the projection.

The rear ends of the left and right half bodies 40 and 50 are received in a carrier 72 of a lining element 72 . Two pins 72 are inserted through the through openings 74 in the chuck element 72 and in the hinge openings 41 and 51 of the rear ends of the left half body 40 and the right half body 50 to the left and right half bodies 40 and 50 with the chuck element 72 in an articulated manner connect. Therefore, the left and right half-bodies can rotate by 40 and 50 around the pins 72 , namely in an open and in a closed state. The front end of the left half body 40 can pivot into the insertion space 60 of the front end of the right half body 50 , the two clamping surfaces 44 and 54 then being opposite one another.

The push-in fixture 80 is a flat wedge-shaped rod that has a narrow lower end and a wide upper end. The push-in fixture 80 has a body which tapers downwards. The lower end of the insertion 80 is inserted through the upper insertion opening 57 of the projection 56 and through the insertion opening 46 of the left half body 40 and through the lower insertion opening 64 of the clamping plate 58 , as shown in FIG. 9, the two halves body 40 and 50 are connected to each other overlapping. The Einsteckbefesti supply 80 , the three insertion openings and the contact surface 62 are positioned exactly on the center line between the two half-bodies (line 11-11 in Fig. 10).

In use, as shown in FIG. 8, the steel support 90 , which is manufactured by the applicant, for example, and as shown in FIG. 3, is not equipped with a connecting ring. A user can attach a plurality of connecting rings 30 to the inner tube 94 and / or the outer tube 92 of the steel support 90 . When attaching, the two half-bodies 40 and 50 are first opened to be attached to the support 90 . Then the front ends of the two half bodies are closed, so that the front end of the left half body 40 extends into the insertion space 60 of the front end of the right half body 50 , as shown in FIG. 9. Accordingly, the clamping surfaces 44 and 54 and the contact surface 62 jointly clamp the outer circumference of the outer tube, as shown in FIGS . 10 and 11. Then the insertion fixture 80 is tapped down into the three insertion openings 57 , 46 and 64 . As shown in Fig. 9, the two side surfaces of the insertion 80 are very closely engaged with the inner wall surfaces of the three insertion openings 57 , 46 and 64 , so that the front ends of the two half bodies 40 and 50 overlap very closely , At the same time, the clamping surfaces 44 and 54 and the contact surface 62 clamp together very closely the outer circumference of the outer tube 92 and engage with it, as shown in FIGS. 10 to 12. Under these circumstances, the connecting ring 30 is very closely and firmly connected to the support 90 .

In addition, if the abutment surface 62 abuts against the wall of the support and if the user flips the insertion fitting 80 downward, this impacted portion (ie, the front portion thereof) of the connecting ring 30 does not drop downward. Therefore, the connecting ring can be held horizontally, even if the plug-in fastening is struck heavily without it tipping. The clamping surface 44 and 54 of the two half bodies 40 and 50 can thus be attached very effectively, with a minimal gap, so that the support is really firmly attached.

In Figs. 10 to 12 it is shown that the connecting ring 30 is applied around the outside lie constricting tube 92 of the steel support 90. With respect to the inner tube 94 of the steel support 90 , which has a smaller diameter, there are two ways of connecting to the inner tube. One possibility is to apply a connecting ring with a smaller diameter to the inner tube. Another possibility is to weld a clamping element 100 to the inner surfaces of the left and right half body 40 and 50 of a connecting ring with the same diameter. The clamping element 100 has a substantially semicircular cross section, as shown in FIGS. 8 and 13 to 15. Such a measure can reduce the inner diameter of the ring body, so that the connecting ring 30 is firmly and tightly fitted on the inner tube 94 . It can be seen from FIGS. 13 to 15 that the inner wall surfaces of the two clamping elements 100 clamp and fix the inner tube 94 without thereby damaging the thread 95 . In addition, the clamping elements 100 clamp the inner tube 94 on a large area, so that a strong binding effect is achieved.

When removing the coupling ring 30, the Einsteckbefestigung is knocked up 80, starting from a state of FIG. 9. After the A stud fastener separated from the insertion opening 46 of the left half body 40 80, the two front ends of the two half bodies 40 and 50 are separated from each other. At this time, the two half-bodies 40 and 50 can be opened and removed from the support.

When the insertion fixture 80 is moved upward, the rivet 82 is stopped on the underside thereof by a shoulder portion 571 which is formed on the upper edge of the insertion opening 57 , as indicated by the broken lines in FIG. 11. Therefore, the insertion fitting 80 is prevented from detaching from the connecting ring 30 . When it is stored, the upper end of the plug-in attachment 80 is tilted downward into a horizontal position, as shown in broken lines in FIG. 6, the plug-in attachment 80 being received in a recess 561 which is attached to one Side of the protrusion 56 is formed to minimize the space required.

The present invention has the following advantages:

• 1. The connecting ring according to the present invention is detachably fitted around the support, which can also be a conventional support, as shown in FIG. 1, around a frame or a steel support 90 according to one of FIGS. 3 or 8 train. Therefore the area of application of the connecting ring is wider. Furthermore, as shown in FIG. 16, in the event that the ground of the place of use is not flat or even, the worker can mount the connecting rings 30 on the supports 90 at the same height in order to connect the connecting elements 120 with the Connection rings 30 easy to connect in the transverse direction. Since the connecting rings 30 are positioned at the same height, the connecting elements 120 , which have a fixed length, can be integrated in the transverse direction. This reduces the cost of the connectors 120 . With a fixed length of the connecting elements and the connecting rings 30 mounted at the same height, the supports 90 can be connected in the transverse direction with very high strength. Therefore, the scaffolding or framework made of these components can carry a higher load.
• 2. The left and right half-bodies of the connecting ring have insertion openings. Therefore, after the attachment to the support, the insertion openings are provided along the entire circumference of the support in order to establish a connection with the connecting elements 120 . Therefore, a plurality of supports, as shown in FIG. 16, can be connected to each other in the transverse direction. In contrast to the conventional structures according to FIGS. 4 and 5, the present invention can very effectively connect the supports in the transverse direction in order to increase the stability. The supports can also be connected diagonally by inclined elements 122 to further increase the stability of the scaffolding.
• 3. The connecting ring according to the present invention has three clamping sections to clamp the support. The contact area is larger, so the Fes activity of the connection is significantly increased or improved.
• 4. When using the connecting ring according to the present invention, the this connecting ring is placed around the support at a certain height, in accordance with the length of the support. The height of the connecting ring is changeable. In addition, it is not necessary to use multiple connecting rings to be provided or mounted on the support so that the costs are reduced become.
• 5. As shown in FIG. 11, the two half-bodies 40 and 50 can be moved in a limited manner in the carrier 72 of the lining element 70 . Therefore, the gap between the two half-bodies is eliminated and the two half-bodies are kept at the same level. Therefore, when the two half-bodies are opened or closed, the two half-bodies are prevented from pivoting up and down and an optimal connecting force can be generated. In addition, the insertion arrangement at the front ends of the two half-bodies can help to keep the two half-bodies at the same level and to reduce vertical swinging.
• 6. The connecting ring according to the present invention makes it possible to connect the supports to one another in many different directions. Therefore, a number of steel supports, as shown in FIG. 8, can be connected to one another in order to build up a systematic or uniform framework which serves as a scaffold. In FIG. 17, a rectangular truss E is set is that serves as part of the backbone. In the assembled state, these units can be connected to one another in the lateral direction and in the longitudinal direction in order to form a large, uniform scaffold, as is shown by way of example in FIG. 18. If it is assembled on site, the corresponding units E can first be installed on the floor. Then the units are lifted with the crane, into the appropriate place, and then assembled in series. This process significantly shortens the time required to assemble the scaffolding, especially at high points, so that efficiency is significantly improved.

In addition, the height of the units can be adjusted. For example, the connecting rings 30 a and 30 b of the support 90 a can be released to adjust the height of the inner tube 94 a. After setting a desired height, the two connecting rings 30 a and 30 b are attached and fixed again. Then the height of another support 90 b can be adjusted. The connecting rings 30 c and 30 d on the support 90 b are made free to adjust the height of the inner tube 94 b. After setting a desired height, the two connecting rings 30 c and 30 d are made festge again. Accordingly, the remaining supports 90 c and 90 d can be adjusted in height so as to adjust the height of the entire scaffold without having to disassemble the units E. This process or work can therefore be carried out very comfortably.

At this point it should be noted that the connection ring according to the the invention, the right half body is provided with a lower clamping plate, where the front end of the left half body overlaps. Such an arrangement can also be modified. For example, this clamp can be in the same Height should be attached like the body of the right half body and the front one The end of the left half body can be attached at a height that is higher than that of the body of the left half body. Accordingly, if the front Ends of the two half bodies are closed, the front end of the left Half body still overlapped with the front end of the right half body.  

The above-described embodiments are provided for illustrative purposes only hen and are intended to describe the present invention, but not the protective cover limit catch. Therefore, there are numerous changes to these embodiments possible without immediately leaving the core of the present invention.

Briefly summarized, a support connection ring according to the invention comprises which is attached and fastened to a building support: two symmetrical half-bodies, which are substantially semicircular, with an inner surface of each Half body is provided with a semicircular clamping surface, as well as a body of each half body with a certain number of insertion openings hen is; the rear ends of the two half-bodies being pivotable with one another are connected, the two half-bodies being opened or closed can; a first insertion opening at a front end of the first half body is formed; a second insertion opening at a front end of the second half body is formed, wherein when the front ends of the two Half bodies are closed, the second insertion opening directly below the first Insert opening is positioned, as well as a rear edge of the front end of the second half body is provided with a contact surface which is positio at a height is kidney, which is lower than the first insertion opening; and with an insert tion, which is designed as a wedge-shaped rod which in the insertion openings two half body is inserted around the two front ends of the two half to connect bodies with each other.
