Description
~L~'7a~7~3 CONNECTING AND PRESSURE-DISTRIBUTING 131,EMENT
FOR CONCRETE STRUCTUR~L MEM~3ERS
This invention relates to reinforced concre-te con~
struc-tion, and more particularly to a connecting and pressure-distributing element for two structural members which are to be concreted in succession in the same plane on a horizontal support and separated from one another by an expansion joint.
A known element has a socket and a bar slidingly insertable in the socket, at least two closed loops made from reinforcing rods, respectively secured to the socket and to the bar, being disposed around and spaced from both the socket and the bar, which socket is intended to be attached to a frontal concrete form and to be embedded with the loops in the structural member to be concreted first, and the bar is intended to be inserted in -the socke-t anchored in the firs-t, set structural member and to be embedded with the loops in the structural member to be concreted later.
Such a connecting and pressure-distributing element is described in European patent application Publication No. 0 119 652 20 (coresponding to applicants' co-pending Canadian patent appli.cation Ser. No. 449,695). A drawback of this design is that when the diameter of the bar is changed, the diameter of the socket wi-th the welded-on loops must be changed in order to enable the bar to be inserted in the socket opening. Hence not only bars bu-t also sockets of different diameters must be used for different purposes. Such connecting and pressure-distributing elements are ~3 - 2 - ,~
7~
used for connectlng structural members in var:;ous typ~s oE
construc-tion, such as for roof slabs, floor slabs, cell:ings, walls, supports, retaining walls, highways, airport runways, and the like, where the structural members are to be fixed in exactly the same plane. The structural members connected by such an element are exposed to the effects of differing temperatures and pressures, so that they should expand and contract in the direction of a joint.
It is an object of this invention to provide an improved connecting and pressure-distributing element in which bars of different diameters can be used without its being necessary to exchange the socket loops on sockets of matching diameters~
The invention provides a connecting and pressure-distributing element for two concrete structural members, which are to be poured in succession in the same plane on a horizon-tal support and are to be separated from one another by an expansion joint, of said element having a socket and a bar slidingly insert-able in the socket, at least two c].osed loops made of reinforcing rods, respectively secured to -the socket and to -the bar, being disposed around and spaced from the socket and the bar, said socket being intended -to be a-ttached to a fron-tal form and to be embedded with the loops in the concrete structural member to be poured first, and -the bar being intended to be inserted in the socket anchored in the first hardened structural member and to embedded with its loops in the concrete structural member to be poured later, wherein the socket comprises a pipe having at least ~.~7~-iO3 25370-5~
three webs of equal height disposed symmetrically around and parallel to its longitudinal axis, over which webs at :Least two steel rings having loops welded on the outside are pressed, said pipe bearing at one end a flange e~tending perpendicular to the longitudinal axis of the pipe and at its other end a vertically adjustable support rod with a lock nut, and wherein a mounting shoe, a-ttachable to the frontal form, is adapted to receive the flange of the pipe in posi-tion attached to the frontal form.
Loops for the connecting and pressure-distributing element may be kept in stock and need not be welded to the socket when the latter is changedO
The webs are preferably longitudinal ribs made in one piece with the pipe, each steel ring having an inside diameter matching the outside diameter of the ribs.
Preferred embodiments of the invention will now be descxibed in detail with reference to the accompanying drawings, in which:
Figure 1 is a perspective view of a socket provided with the spiral-shaped loops, Figure 2 is a perspective view of a mounting shoe for receiving one end of the socket of Figure 1, Figure 3 is a cross-section through the socket of Figure 1, withou-t the loops, in a first embodiment of the invention, Figure 4 is a cross-section through the socket o~ Figure 1, without the loops, in another embodiment of the invention, Figure 5 is an elevation of a steel ring of the socket of Figure 1, to which ring a spiral-shaped loop is welded, -~., - 3a -~ ., ~-, ~74~7~3 F'igure 6 i5 a perspective view o:E the oper~tion at the time of pouring the first concrete structural member, the mounting shoes being attached to the frontal concrete :Eorm for receiving the sockets, and Figure 7 is a sec-tional view of the socket embedded in the first member poured, from which the fron-tal concrete form has been pulled off, - 3b -, ~;
~.~7~7~
and of the bar inserted in the socket and embedded in the ~tructural mem ber subsequently poured.
The element depicted in the drawings is used to connect two con-crete structural members 2, 3 to be poured successively in the same plane on a hori~ontal support 1 and to be separated by an expansion joint 4 as is customary especially in highway and airport runway construction (see Figure 7). The element embedded in the structural members, which are ex-posed to varying temperatures, enables them -to expand and contract with-out constraint. Furthermore, the element serves to distribute over a greater area in the concrete the forces occurring especialiy during ex-pansion and contraction of the structural members.
The connecting and pressure-distributing element comprises a socket 5, a mounting shoe 16, and a bar 6 slidingly insertable into the opening in socket 5. Socket 5 comprises a pipe 9 having at least three webs 10 of identical height disposed symmetrically around pipe 9 and parallel to its longitudinal axis x. Socket 5 further comprises at least two steel rings 11 which are pressed onto webs 10. Welded to each ring 11 from outside is a loop 7 having a spiral-like shape. Each loop 7 is made from reinforcing rods, which are not, however, as thick as the rods of the main reinforcement 20 (Figure 6). Pipe 9 bears at one end 9a a flange 12 extending perpendicular to longitudinal axis x and at the other end 9b a vertically adjustable support rod 13 which can be locked at the desired height by means of a nut 14. Support rod 13 likewise runs perpendicular to longitudinal axis x in a bore made through a bolt 15 on which lock nut 14 is threaded.
Webs 10 are longitudinal ribs made in one piece with pipe 9. The at least two steel rings 11 have the same inside diameter as the out-side diameter of these ribs, so that rings 11 must be pushed over the ribs by means of a press or driven on with a hammer. Loops 7 are welded to rings 11.
As may be seen from Figures 3 and 4, the pipes 9 may have different inside diameters and webs 10 of accordingly differing heights. Rings 11, which all have the same inside diameter and to which loops 7 are welded, may thus be pressed onto pipes 9 having various inside diameters. Rings ~7~
11 with welded-on loops 7 may thus be kept in stock in large quantities.
Pipes 9 with different inside diameters are then used for bars fi of dif'-ferent diameters.
The moun-ting shoe 16 shown in Figure 2 has a U-shaped aperture in-tended to receive one end 9a of pipe 9. Mounting shoe 16 is attached to a frontal concrete form 8 by means of nails driven through nail holes 21 provided for -that purpose. The face of mounting shoe 16 next to frontal concrete form 8 is stepped inwardly around aperture 17 to form a slide-in recess 22 for receiving flange 12. The face of mounting shoe 16 remote from frontal concrete form 8 is provided with two anchoring ribs 18, one on each side of aperture 17. By means of ribs 18, firm anchoring in the concrete of structural member 2 is achieved. The lateral edges of mount-ing shoe 16 include centering slots 19 to facilitate attachment thereof to frontal concrete form 8 and are chamfered toward aperture 17 on the side facing frontal concrete form 8 to achieve firm anchoring when frontal concrete form 8 has been pulled off the first structural member 2 after setting.
Support rod 13 is of steel and has a diameter of about 5 mm. It is guided through bolt 15 and is vertically adjustable therein. Rod 13 serves to support the other end 9b of pipe 9 while socket 5 is being em-bedded in structural member 2. By means of this support, the pressures of the concrete poured to form structural member 2 are intercepted so that socket 5 is not pushed out of its position.
Figure 7 shows two structural members 2, 3 with the embedded socket 5, mounting shoe 16, and bar 6. Here the frontal concrete form has been pulled off the first, set structural member 2, bar 6 inserted in the opening in socket 5, and the second structural member 3 then poured, with bar 6 being embedded therein. Expansion joint 4, formed upon removal of frontal concrete form 8 and filled with insulating material, may also be seen between structural members 2 and 3. After structural member 3 has set, the connection is established. Bar 6, from 16 to 40 mm in diameter, which must match the diameter of the opening in socket 5, is slidingly inserted in the latter.
The connecting and pressure-distributing element described above is ~X7~V3 produced complete at the factory. A-t the construction sitel it is merely adjusted in height and put together. Assembly is very simple as the mounting shoe need only be attached to the frontal concrete form at the desired height and the socket slipped by its flange into the slide-in re-cess of the mounting shoe. The other end of the socket is supported at the desired height by the support rod. Thus, the socket can no longer come down during mounting of the heavy main reinforcement. The loops en-sure better distribution of the pressure in the two structural members.

Loops for the connecting and pressure-distributing element may be kept in stock and need not be welded to the socket when the latter is changedO
The webs are preferably longitudinal ribs made in one piece with the pipe, each steel ring having an inside diameter matching the outside diameter of the ribs.
Preferred embodiments of the invention will now be descxibed in detail with reference to the accompanying drawings, in which:
Figure 1 is a perspective view of a socket provided with the spiral-shaped loops, Figure 2 is a perspective view of a mounting shoe for receiving one end of the socket of Figure 1, Figure 3 is a cross-section through the socket of Figure 1, withou-t the loops, in a first embodiment of the invention, Figure 4 is a cross-section through the socket o~ Figure 1, without the loops, in another embodiment of the invention, Figure 5 is an elevation of a steel ring of the socket of Figure 1, to which ring a spiral-shaped loop is welded, -~., - 3a -~ ., ~-, ~74~7~3 F'igure 6 i5 a perspective view o:E the oper~tion at the time of pouring the first concrete structural member, the mounting shoes being attached to the frontal concrete :Eorm for receiving the sockets, and Figure 7 is a sec-tional view of the socket embedded in the first member poured, from which the fron-tal concrete form has been pulled off, - 3b -, ~;
~.~7~7~
and of the bar inserted in the socket and embedded in the ~tructural mem ber subsequently poured.
The element depicted in the drawings is used to connect two con-crete structural members 2, 3 to be poured successively in the same plane on a hori~ontal support 1 and to be separated by an expansion joint 4 as is customary especially in highway and airport runway construction (see Figure 7). The element embedded in the structural members, which are ex-posed to varying temperatures, enables them -to expand and contract with-out constraint. Furthermore, the element serves to distribute over a greater area in the concrete the forces occurring especialiy during ex-pansion and contraction of the structural members.
The connecting and pressure-distributing element comprises a socket 5, a mounting shoe 16, and a bar 6 slidingly insertable into the opening in socket 5. Socket 5 comprises a pipe 9 having at least three webs 10 of identical height disposed symmetrically around pipe 9 and parallel to its longitudinal axis x. Socket 5 further comprises at least two steel rings 11 which are pressed onto webs 10. Welded to each ring 11 from outside is a loop 7 having a spiral-like shape. Each loop 7 is made from reinforcing rods, which are not, however, as thick as the rods of the main reinforcement 20 (Figure 6). Pipe 9 bears at one end 9a a flange 12 extending perpendicular to longitudinal axis x and at the other end 9b a vertically adjustable support rod 13 which can be locked at the desired height by means of a nut 14. Support rod 13 likewise runs perpendicular to longitudinal axis x in a bore made through a bolt 15 on which lock nut 14 is threaded.
Webs 10 are longitudinal ribs made in one piece with pipe 9. The at least two steel rings 11 have the same inside diameter as the out-side diameter of these ribs, so that rings 11 must be pushed over the ribs by means of a press or driven on with a hammer. Loops 7 are welded to rings 11.
As may be seen from Figures 3 and 4, the pipes 9 may have different inside diameters and webs 10 of accordingly differing heights. Rings 11, which all have the same inside diameter and to which loops 7 are welded, may thus be pressed onto pipes 9 having various inside diameters. Rings ~7~
11 with welded-on loops 7 may thus be kept in stock in large quantities.
Pipes 9 with different inside diameters are then used for bars fi of dif'-ferent diameters.
The moun-ting shoe 16 shown in Figure 2 has a U-shaped aperture in-tended to receive one end 9a of pipe 9. Mounting shoe 16 is attached to a frontal concrete form 8 by means of nails driven through nail holes 21 provided for -that purpose. The face of mounting shoe 16 next to frontal concrete form 8 is stepped inwardly around aperture 17 to form a slide-in recess 22 for receiving flange 12. The face of mounting shoe 16 remote from frontal concrete form 8 is provided with two anchoring ribs 18, one on each side of aperture 17. By means of ribs 18, firm anchoring in the concrete of structural member 2 is achieved. The lateral edges of mount-ing shoe 16 include centering slots 19 to facilitate attachment thereof to frontal concrete form 8 and are chamfered toward aperture 17 on the side facing frontal concrete form 8 to achieve firm anchoring when frontal concrete form 8 has been pulled off the first structural member 2 after setting.
Support rod 13 is of steel and has a diameter of about 5 mm. It is guided through bolt 15 and is vertically adjustable therein. Rod 13 serves to support the other end 9b of pipe 9 while socket 5 is being em-bedded in structural member 2. By means of this support, the pressures of the concrete poured to form structural member 2 are intercepted so that socket 5 is not pushed out of its position.
Figure 7 shows two structural members 2, 3 with the embedded socket 5, mounting shoe 16, and bar 6. Here the frontal concrete form has been pulled off the first, set structural member 2, bar 6 inserted in the opening in socket 5, and the second structural member 3 then poured, with bar 6 being embedded therein. Expansion joint 4, formed upon removal of frontal concrete form 8 and filled with insulating material, may also be seen between structural members 2 and 3. After structural member 3 has set, the connection is established. Bar 6, from 16 to 40 mm in diameter, which must match the diameter of the opening in socket 5, is slidingly inserted in the latter.
The connecting and pressure-distributing element described above is ~X7~V3 produced complete at the factory. A-t the construction sitel it is merely adjusted in height and put together. Assembly is very simple as the mounting shoe need only be attached to the frontal concrete form at the desired height and the socket slipped by its flange into the slide-in re-cess of the mounting shoe. The other end of the socket is supported at the desired height by the support rod. Thus, the socket can no longer come down during mounting of the heavy main reinforcement. The loops en-sure better distribution of the pressure in the two structural members.
