Definitions
- the present invention relates to scaffolding unit intended to form working stages and the support structures required in work for use in connection with repair, installation, and maintenance work on bridges and other structures with a deck.
- the invention relates to the creation of repair scaffolding for bridges.
- Publication WO2008132277 discloses one scaffolding arrangement suitable for repair work on a bridge deck.
- the arrangement consists of a number of scaffolding supports to be installed on the deck of the bridge, which are supported from the bridge by bolting the support to the upper surface of the deck of the bridge and then carrying the support on rotatable support elements on the undersurface of the deck.
- Publication O2012062968 discloses an attachment element for attaching a scaffolding support to the deck of a bridge.
- the scaffolding support to be attached is arranged to be carried on two support points to the upper side of the deck of the bridge. At least one of the support points is arranged to take the compressive force of the attachment elements attached to the deck of the bridge and at least one is arranged to take the tensile force.
- the attachment element is arranged to be detachably attached to the deck of the bridge with at least two attachment means and com- prises at least one attachment means for attaching the attachment element to the support point taking the tensile force of the scaffolding support.
- scaffolding supports must be able to carry quite a large load of repair tools, repair workers, and possibly casting formwork and similar, the supports easily become quite massive. Thus, lifting means are needed to handle them and heavy vehicles to transport them. In addition, the installation of the supports usually requires several peo- pie. All these factors increase the repair costs.
- the scaffolding also requires special attachment devices, such as bolts running through the bridge deck and possibly a flat surface in the deck for attachment.
- the formwork required for repairing and casting the edge of the bridge must be moved with jacks and continuous casting in the longitudinal direction of the bridge or deck is not possible. Work is also hindered by the support required by the scaffolding against the undersurface of the bridge.
- the present invention is intended to create a solution, in which the position of the support level formed by the scaf ⁇ folding can be easily altered in the height ' direction .
- the invention is also intended to create a solution, in which adjustment of the height direction does not alter the lateral positioning.
- inventions embodiments are intended to create scaffolding, which can, when desired, be transported in parts and assembled at the point of use.
- inventions embodiments are intended to create scaffolding, the structure of which is simple and easily manufactured.
- the invention' s embodiments are also intended to permit the adjustment within wide limits of the location of the scaffolding' s work stages, formwork, and other structures at least in the height direction of the bridge deck, preferably also in the transverse direction relative to the longitudinal direction of the deck level.
- the invention's embodiments are also intended to permit adjustment of the scaffolding's height-direction position relative to the deck of the bridge or other level at least partly from the top of the deck of the bridge or similar, most preferably from the side of the attachment frame of the scaffolding opposite to the edge of the deck.
- the invention is based on the attachment elements connecting the scaffolding to the bridge deck being attached to the set of carrier arms by means of a pivoted rectangle, preferably a pivoted parallelogram.
- the scaffolding can be dismantled into parts and assembled at the point qf use.
- one scaffold- ing unit comprises only one operating device for altering the vertical position of the set of carrier arms.
- the structure of the scaffolding unit according to the invention is light, but can nevertheless be dimensioned to carry a large load, which is required for carrying the devices and materials to be used in bridge repair work.
- the scaffolding unit can be easily dismantled into parts for transportation and assembled at the point of use. Heavy lifting devices are not needed to move the parts and in ⁇ stallation of the scaffolding can be done even by one workman.
- One of the most important advantages of the invention is that the location of the carrier level formed with the aid of the scaffolding, relative to the undersurface of the bridge, can be easily altered within a large adjustment range without the angle of the carrier level- or the dis ⁇ tance from the edge of the deck essentially changing.
- the components of the scaffolding are plate and beam structures, so that it is cheap to manufacture. In principle, the assembly of the scaffolding unit requires only the pivot pins to be set in place, so that installation work is easy and special tools are not required.
- Figure 1 shows a side view of the scaffolding unit accord ing to the invention.
- Figure 2 is an exploded view of the scaffolding unit of Figure 1.
- Figure 3 shows the scaffolding unit of Figures 1 and 2 in a first adjustment position.
- Figure 4 shows the scaffolding unit of Figures 1 and 2 in a second adjustment position.
- Figure 5 shows a second embodiment of the invention.
- the downward direction is the direction from on top of the deck structure pointing towards its upper surface and the direction pointing upwards is the direction opposite to that.
- the scaffolding unit con- sists of a set of carrier arms 2 for forming work levels and for carrying the work machines and formwork required in the work and connecting the set of arms of the attachment frame 1 to the upper surface of the bridge or other deck structure 15 and for adjusting the ' attitude and location of the scaffolding.
- the set of arms 2 comprises a vertical arm
- the lower beam 3 is a triangular beam or one that is otherwise reinforced at the location of the jack, which, when triangular, comprises a straight lower beam and a triangle formed on top of the lower beam, which consists of two sloping beams and a vertical support connecting the point of the triangle and the lower beam.
- the advantage of this beam construction is lightness and a good load-bearing capacity.
- the upper and lower beams 3, 11 are attached to the attachment frame 1 by means of pivot pins 6 to pivot point 12 and 17 located at a distance from each other vertically, in such a way that the upper beam 11 is attached to pivot point 12 in the upper part of the attachment frame 1 and the lower beam 3 to pivot point 17 beneath it in the lower part of the attachment frame 1.
- the pivot points 12 and 17 of the attachment frame are on the same ' vertical straight line, but by altering the locations of the pivot points the paths of motion of the set of arms can, if necessary, be altered.
- the upper and lower beam 3, 11 are attached by pivot pins 6 to lugs 13 in the end of the vertical arm 4, in which are also formed ' on top of each other on the same straight line in the vertical direction the pivot points 16, 18 to the upper beam 11 and the lower beam 3.
- the pivot points 12, 16, 17, and 18 form, together with the upper and lower beams 3, 11 a pivoted parallelogram, with the aid of which the vertical arm 4 and the transverse carrier beam 5 at its lower end can be moved vertically.
- the transverse carrier beam 5 is attached by pivot pins 6 to lugs 14 at the lower end of the vertical arm 14. In this attachment method, the transverse carrier beam 5 is locked to the horizontal attitude and the pin attachment is intended to create an easily assembled joint.
- the attachment frame 1 can comprise attachment plates, which form a stand arrangement, which preferably includes attachment bolts that can be adjusted vertically, to attach the scaffolding to the bridge deck. The attachment bolts can be fitted into holes drilled in the bridge deck and secured with a chemical binding agent, thus making the attachment strong and reliable.
- the operating device is a jack 9, which is installed on top of the attachment frame 1 between the attachment frame 1 ⁇ and the pivoted parallelogram's triangularly shaped lower beam 3.
- the jack 9 is located at the vertical support under the point of the beam triangle, so that a strong working point is obtained for the jack 9.
- the jack 9 can be a simple screw jack, a hydraulic jack, or some similar lifting device. Because continuous adjustment of the vertical position is not need- ed, the jack can be a simple and strong device.
- the scaffolding is in the upper position and in Figure 4 in the lower position.
- the vertical arm 4- of the scaffolding remains precisely vertical and the carrier beam 5 horizontal.
- the margin of movement of the height adjustment is quite large. This is an extremely important advantage compared to previously known solutions, because in these the adjustment margins have been quite limited and the adjustments diffi ⁇ cult to make.
- the scaffolding of Figure 5 differs slightly from that described above.
- the scaffolding's lower beam 3 is unified, not necessarily straight, and continues to the opposite side of the pivot point between the attachment frame 1 and the lower beam 3 relative to the vertical arm 4.
- the lower beam 3 thus forms a lever extending to both sides of the lower pivot point 17 of the attachment frame 1.
- a hydraulic jack 21 and a screw jack 22 is fitted to the end of this lever, also on the opposite side of the pivot point between the attachment frame 1 and the lower beam 3, relative to the vertical arm 4.
- the shafts of the jacks 21, 22 are supported on the stand 20 of the attachment frame 1.
- Both jacks can be used independently to adjust the position of the vertical arm 4 and the carrier beam 5 with the arm of the lever formed by the lower beam 3, but the adjustment is preferably made with the aid of the hydraulic jack while the position of the scaffolding is locked with the screw jack 22.
- the terms hydraulic jack and screw jack refer to any hydraulic or screw-operated operating device whatever, by changing the length of which compression, or tractive force, or locking in position are achieved.
- the adjustment of position and locking can be done with only a screw jack if desired, but a hydraulic jack can be used as an aid in adjusting the height, or in parallel with the screw jack. Other operating devices or power tools are not required here.
- the adjustment can be made easily and safely on the opposite side of the attachment frame to the bridge deck.
- the lever can also be formed in a corresponding manner in the upper beam 11 or in both beams 3, 11. It is then possible to optionally fit either of the jacks to the upper beam and the other to the lower beam or both ' in connection with either the lower beam or upper beam.
- the scaffolding unit (attachment frame 1) is preferably attached to the deck of the bridge or other structure with the aid of screwed bolts 23 from the stand 20. Attachment to the deck takes place by gluing or casting the bolts into blind holes made in the deck.
- the attachment is made from two stands 20 at a distance from each other and with the aid of the screwed bolts the scaffolding can be raised from the deck, so that a gap 24 forms between the scaffolding and the deck.
- the deck surface can then be worked on and the surface cast with the scaffolding attached.
- the positioning of the scaffolding unit in the height direction relative to the deck of the bridge or other structure takes place by altering, in addition to the pivoted parallelogram, the locations of the attachment points (pivot points) 16 and 18 between the vertical arm 4 and the pivoted parallelogram 12, 16, 17, 18.
- attachment holes 25 on top of each other, which have a predefined distance between them.
- lugs 26 which are arranged on both sides of the vertical arm and in which there are also attachment holes 27 on top of each other, which have a predefined distance between them.
- the distances between the vertical arm's attachment holes 25 are greater than the distances between the lugs' 26 attachment holes 27.
- FIG. 5 shows a dense hole distribution in the carrier beam 5 and four holes in the attachment lugs of the vertical arm. This hole distribution is also flexible and the number and distribution of the holes can be altered to create an adequate adjustment precision. Though a dense hole distribution can also be made in the long load-bearing components such as the vertical arm or the carrier beam, in these it is preferable to use a larger hole distribution, to minimize the number of holes and preserve strength.
- a pivoted parallelogram is preferably used, but the lengths of the sides and the location of the pivots can be altered as required, making it a pivoted rectangle .
- the scaffolding there can be integrated : working ' stages and these can include rails or attachments for formwork, tools such as abrasive water jets, or handrails.
- the scaffolding can be attached to a rail in the bridge deck, so that it can be moved as work progresses parallel to the deck.
- the attachment components there can be toolboxes for the safe storage of tools and other materials and lifting hooks or similar can be installed in the scaffolding so that it can be moved as an entire system.
- the scaffolding unit according to the invention can be transported to the work site ready assembled or dismantled into its principal components. Assembly of the scaffolding unit takes place simply by installing the pivot pins 6 in place and locking them with cotters. Thus in principle, the assembly of the scaffolding unit requires no tools at all.
- the scaffolding unit is easily dismantled into relatively light parts and can be moved to a new location after use. Because several scaffolding units are required for a bridge deck or similar work site, significant advantages are achieved with the aid of easy. assembly, disassembly, and transportation. In place of pivot pins and cotters it is possible, of course, to use other corresponding attachment elements such as bolts and nuts.
