Definitions

  • This invention relates to concrete formwork. It is particularly concerned with formwork of the type employed to produce walls, especially formwork for producing curved walls.
  • One type of concrete formwork is known from British Patent GB-A-2133826. This describes formwork for producing curved walls comprising a deformable panel and a plurality of U-shaped members secured to the panel by their legs and arranged in at least two columns.
  • a soldier i.e., a structural member comprising two, spaced connected beams with aligned holes therein, spans across two or more support members in the same column and is connected thereto by a way of the faces of the members.
  • the outer faces of two adjacent soldiers are connected by an adjustable tie whereby the distance between the soldiers may be altered to vary the curvature of the panel. Any desired height can be accommodated simply by altering the number of U-shaped members in each column and employing different lengths of soldier.
  • the soldiers provide rigidity. In use, two panels, each supported by a plurality of U-shaped members and soldiers, are positioned a distance apart and concrete is cast between them to form a wall.
  • ties are employed which extend between, and beyond the outer sides of, the panels. These ties serve to hold the panels together. Generally they are threaded and, once inserted through the panels, correspondingly threaded nuts are attached to their ends. The nuts are screwed down to pull the panels together and enable them to resist the forces generated by the concrete to be poured therebetween.
  • the bases of the U-shaped members are formed with holes so that the ties can pass through the members and then between the webs of the soldier.
  • the nuts, employed with the ties are bolted down against the outer pair of flanges of the soldier. The soldiers serve to evenly distribute loads generated by the pressure of the concrete acting on the panels which is passed through the ties and the-U-shaped members.
  • French Patent FR-A-2613747 describes concrete formwork including a panel supported by support members comprising wooden beams arranged in pairs.
  • a bracket is attached to each pair of wooden beams by screws.
  • the bracket defines a C-shaped socket for receiving the cross flanges at one end of an I-shaped beam therein.
  • the I-beam is formed from two U-beams connected back to back.
  • the cross flanges at the end of the I-beam have a fixed stop at one extremity and a releasable stop at the other to permit insertion thereof into, and retention thereof by, the C-shaped sockets of the bracket members.
  • I-beams are attached between each adjacent alternate pair of support members, a tie being connected to each beam rather than to each support member.
  • each bracket member includes a support post with an aperture therein whereby it may be attached to a soldier by pinning through the aperture and one of the pairs of aligned holes in the soldier and in that each bracket member also provides a second opposing surface for abutment by the opposite side of the beam to retain the beam in position between the soldiers.
  • ties to be provided at locations other than at the soldiers, that is, a greater number of possible tie positions are available.
  • Known ties are, in fact, capable of supporting greater loads than those to which they are subjected in formwork, such as that known from GB-B-2133826.
  • one tie can be used to support a number of soldiers. Therefore the number of ties which has to be employed is less. The resultant reduction in making good which has to be done to a concrete section is significant.
  • one tie is employed per alternate adjacent pair of soldiers.
  • each bracket member includes an angled portion against the apex of which, in use, the beam abuts.
  • the bracket member may be arranged so that the apex of the angled portion lies between the webs of the soldier to which the bracket member is connected, preferably in the median plane of the soldier. Load transferal to the soldier is therefore along its centre line.
  • the bracket member may further comprise a circular rod spaced from the apex of the angled member, the beam in use passing between the circular rod and the angled member.
  • the distance between the rod and the angled member is made approximately equal to the appropriate beam dimension.
  • the panels may be deformable and the soldiers may additionally be connected by adjustable length link means.
  • the formwork is then suitable for use in the construction of curved walls.
  • Figure 1 shows a section of concrete formwork 2 comprising a panel 4, U-shaped members 6, soldiers 8 and a tie 10.
  • the panel 4 forms part of a panelling wall which is connected to a plurality of the U-shaped members 6.
  • the U-shaped members 6 basically comprise two inclined legs 12 joined together by a base flange 14.
  • the members 6 are secured to the panelling wall through holes in end flanges 16.
  • the plurality of U-shaped members 6 are arranged in a series of columns spaced around the panelling wall.
  • One soldier 8 spans over the U-shaped members 6 in a column to act as a continuity member therefor.
  • the members 6 include support posts (not shown) carried on the base flange 14 thereof. These support posts extend between the webs of the soldiers 8 and are connected thereto. The ends of the support posts extend beyond the soldiers 8 and are arranged to be connected to a turn buckle. Turn buckles are provided between each pair of soldiers and, by employing these to vary the distance between the soldiers, the curvature of the panelling wall can also be varied.
  • the complete concrete formwork includes a second panelling wall, supported by U-shaped members and soldiers, which is spaced from the first so the concrete can cast therebetween.
  • ties are employed which extend between the panelling walls, the ties being held in place by securing their ends which lie on the outer sides of the panelling walls.
  • the ties serve to pull the two sections of the formwork together against the pressure exerted by the concrete to be cast therebetween. Once casting is complete, at least a portion of the ties are removed from the cast concrete with the result that this is left with holes which have to be made good.
  • the ties have been attached by way of the panel supports in whatever form these were provided.
  • the ties pass through holes in the base flanges 14 of the U-shaped members 6 between the webs of the soldiers 8 and their ends are closed by nuts which are tightened up against the flanges of the soldiers 8.
  • At least one tie per column of U-shaped members 6 has to be provided and often two or three per column are necessary.
  • a bracket 18 is attached to each soldier.
  • the bracket 18 comprises a support post 20 dimensioned to fit between the webs of the soldier 8 and formed with a hole 22.
  • the brackets 18 are connected to the soldiers 8 by passing a pin, see 24, through holes in the soldier 8 and the holes 22 in the support post 20 of the bracket 18.
  • the support post 20 carries a baseplate 26 from which two trapezoidal shaped wings 28 extend, the long edge of the wings 28 being connected to the baseplate 26. At their free ends the wings 28 are connected by a circular rod 30.
  • An angle member 32 is mounted to the baseplate 26 between the other ends of the wings 28.
  • a bracket 18 is mounted to each soldier 8 by pinning it thereto. With the brackets 18 in place, a beam 34 can be attached between two of the soldiers 8 by passing it through the apertures of the brackets 18 defined by the wings 28, rods 30 and angled member 32. The distance between the rods 30 and the angle member 32 of the brackets 18 can be so arranged that, no matter at what angle the soldiers 8 are to each other, the beam 34 will be held by the brackets 18 between the apices 36 of the angle members 32 and the rods 30.
  • the beams 34 which are preferably hollow sections, include holes therein through which a tie 10 can be passed.
  • the beams 34 have a plurality of such holes so that the ties 10 can be provided wherever desired.
  • a tie 10 is held in position relative to a beam by attaching a washer 38 and a nut 40 to its free ends.
  • the beams 34 provide additional tie locations.
  • a tie 10 is capable of supporting more than one soldier 8 and, by providing the beams 34, a tie 10 can be positioned so that it will do this.
  • a tie 10 is provided between each alternate adjacent pair of beams 34. Therefore the amount of holes in the concrete cast between the first and second panels of the formwork is halved, with a consequent 50% reduction in the necessary "making good".
  • the angled member 32 of the brackets 18 is positioned so that, when a bracket 18 is connected to a soldier 8, its apex 36 lies on the centre line of the soldier which passes between the webs thereof. Loading on the beam 34 will therefore be transmitted, by the contact thereof with the apices 36 of the brackets 18, through the middle of the soldiers 8. This maximises the strengthening effect of the beams 34.
