Description

  The present invention relates to scaffolds for supporting stools, siding boards, and formwork, and in particular, the present invention relates to scaffolds for the building and construction industries.

  Traditionally, scaffold systems are used during the construction and / or maintenance of large-scale structures such as, for example, buildings, silos, ships, monuments, and dams. Scaffolds are generally erected on the outside of such constructs and are not commonly used inside. The scaffold, once set up, provides practical access to the building area, is otherwise difficult to access, and is otherwise impossible to reach. In general, such areas are at a height that is beyond the reach of practical ladders and ladders. This system allows workers to work safely and efficiently at a height above the ground or structure foundation level, and also allows safe storage and placement of work materials. Conventional systems generally stand up from the ground, where upright poles are supported on the ground surface and interconnected via a network of cross members and / or step stools, providing stability and rigidity to the framework configuration. give. It is usually necessary to extend the scaffolding as the lower level of the construction is completed or the maintenance work moves upwards. This sometimes necessitates connecting additional uprights to the first upright supported on the ground, and it is necessary to further interconnect the cross members etc. to add stability. As the system gets taller, it may be necessary to attach or secure the scaffold to the construct for additional safety and stability. Once assembled, the traditional scaffolding form is fixed to the structure and cannot be moved unless there is a critical event if the whole is not disassembled. Thus, if the construction work continues to extend upward, the lower level of the scaffold may become unnecessary, wasted waste material, and the scaffold will continue to extend to work at a higher level In order to do this, it is necessary to bring more materials.

  Solutions to these problems have been proposed so far by so-called “second generation” systems. One system known in the prior art is a removable “jump” or “hang” scaffold system. In such a system, the scaffold is stood in a limited height range and is directly anchored to the structure. As work progresses to higher construction or maintenance levels, the scaffold can be removed from the structure and lifted one unit at a new height as required by the crane. Each scaffold unit is then reinstalled and reattached to the structure at a new height. However, such a system is only adapted to scaffold units with an area of approximately 3 to 4 square meters due to the practical limitations in moving and lifting large sections of unit scaffolds by crane. Typically, due to its properties, such systems are used in urban areas or confined areas with limited gap spacing or safety areas. In addition, when performing any of the operations of raising, moving, and re-fixing, it is necessary to consider an average weather condition until the scaffold is safely fixed again. In bad weather conditions, such as strong winds or limited visibility, it is impractical and unsafe to hang a large scaffold unit from a crane into free space. Under such circumstances, re-installation will also be difficult and will be dangerous. Since moving the section of such a system is impractical as described above, the unit will need to be smaller than the preferred size if such conditions are not present, and is therefore necessary. As the number of units increases, more crane operations and additional cranes are required to move them. The high number of scaffolding units associated with the problems associated with such unit movement results in increased construction time and cost as well as increased safety risk associated with unit movement in free space by the crane.

  An alternative system that has been proposed is an automated or “self-propelled climbing” system. Such a system is a self-propelled climbing assembly that is typically used primarily as a vertical wall formwork to form a concrete surface. US Pat. No. 5,500,287 issued to Schworer discloses such a system of “self-propelled climbing” formwork for standing concrete walls. The system includes a scaffolding platform, which is moved by one hydraulic linear drive per rail along an upright transport rail mounted on the wall portion. As the platform is driven to the top of its respective rail, the platform is maintained in that position while the rail continues to be moved upward and secured to the next part of the wall. Thus, in order to advance the platform upward, the system requires a relatively complex two-step process of alternating movement: the platform, then the rail, then the platform.

  US Pat. No. 4,060,385 issued to Fougea is a further well-known system of self-propelled climbing formwork. This system discloses the use of hydraulic actuators to advance and position the formwork frame along the wall under construction. The frame is provided with a plurality of hydraulic actuators, each actuator having one end attached to move the frame along the wall and the other end of each actuator being a bracket mounted on the wall Suitable for hooking on top. During frame movement, a slanted cam engages the bracket to maintain the frame in the required position. The slide carrying arm must then be placed in place to support the frame and then removed to allow the frame to be advanced upward relative to the wall.

  Thus, unlike the system described above, the self-propelled climb system, which requires a relatively small amount of movement along the wall under construction, was incorporated rather than moved by a crane. Shifted automatically by hydraulic jack or ram. Such a system avoids the above-mentioned problems associated with hoisting the unit in free space by a crane, but is relatively expensive and complex and difficult to install. Usually such a system requires a plurality of hydraulic actuators, which also need to be synchronized to maintain a constant and unobstructed movement of the frame without catching on the rails.

  Therefore, it would be advantageous to provide a scaffold system that reduces the above-mentioned problems and limitations associated with prior art systems.

  Furthermore, it would be advantageous to provide a method for deploying a scaffold system that reduces the above-mentioned problems associated with prior art systems.

DESCRIPTION OF PREFERRED EMBODIMENTS

  A scaffold system according to a specific embodiment of the present invention will be described hereinafter with reference to the drawings.

  The term “scaffold assembly” means a configuration of elongate rail members that are interconnected and upright, such as by cross members, step stools, and / or formwork, that form a framework for installation to a structure. A side view of one form of assembly is shown in FIG. It is shown in 1b-1d. It will be appreciated that the elongate members are joined end to end depending on the overall height required and thus the height of the assembly. The plurality of elongate members alternate with the cross members to form a pre-selected width unit or modular scaffold assembly or to suit a particular situation such as, for example, a construction with a unique exterior wall angle. Are interconnected laterally.

  FIG. 1a shows the first bracket 3 of the scaffold system 1 of the present invention installed at the lower level 4 of the building under construction. Although the bracket is shown in a through beam clasp configuration, a through slab and a buried beam / slab clasp configuration are also envisioned. FIG. 1b shows the assembled scaffold assembly 2 extending upwards from the ground surface 5 and is bridged at the first lower level 4 and the second higher level 6 of the construction. The assembly is held at a first level 4 by a bracket 3. The second higher level shows the under construction condition, so the bracket is not yet provided. The scaffold assembly consists of a plurality of upstanding elongated members 7 that are joined and interconnected to form a unitary framework. The work platform 8 and the cross member 9 help to provide rigidity and strength to the framework of the assembly 2.

  FIG. 1c shows a second higher level bracket 3 installed in the building at the second higher level 6 of the construction work. The assembly 2 is again shown being held by the bracket 3 at the second level 6. The third highest level 10 depicted in the figure shows the state under construction. This is the level at which the top step 8 needs to be raised so that it is useful without further extending the scaffold assembly 2.

  The assembly raised to the third higher level 10 is shown in FIG. It is shown in 1d. The base of the assembly is subsequently raised away from the ground surface 5 and the assembly is clamped in place by holding means. The holding means is incorporated in the bracket 3 in this example. The work can now be carried out at the highest level 10 currently under construction. The waste of scaffold material is not at the ground level, and it is still possible for workers to access the lower level 4 and the second level 6. Thereafter, brackets may be added to the highest level and the assembly 2 may be raised further up. The range that the scaffolding system can reach is actually only limited by the highest level of construction and the lifting capacity of the lifting means used, for example the reach limit or weight limit of the crane. FIG. 1a to FIG. 1d shows the brackets 3 installed at the upper and lower levels, but additional brackets 3 are provided adjacent to them at practically the same level, and the brackets 3 holding the assembly 2 are in a grid or row It should be understood that it is effectively formed. Modular or unit section of assembly 2

  FIG. 2a to 2f show the operation sequence of one embodiment of the bracket 3 and the assembly support means. The bracket 3 is attached to the FIG. It is shown in each drawing of 2a to 2f. In this example, the installation is by through beam stop arrangement 24. The bracket 3 includes support means in the form of a pivotable arm 25. The arm 25 is shown pivotally connected to the bracket 23 at its inward end. The outward end is configured to include a brace for engaging the support pin of the elongated member 22. The arm also includes stop means (not shown) for engaging the body of the bracket 23 when in the horizontal position. The stop means prevents the outward end of the arm from pivoting below the horizontal position. In this example, the arm is not intended to pivot below the horizontal direction, but in other configurations and arrangements of the bracket 23, the elongated member 22 may pivot downward depending on the requirements of the particular configuration. It will be appreciated that support means may be included. The outward end of the arm 25 is configured to support a rail pin 27a inserted through the opening 26 of the elongate member 22, whereby the elongate member 22 is supported by the bracket via the arm and pin 27a. If one pin 27a fails, one or more additional pins 27b may be positioned above the first pin to provide relief support for the elongated member 22. .

  FIG. Referring to FIGS. 2a shows an elongate longitudinal upright member of the scaffold assembly 2 in the form of a rail 22 of normal cross section. The rail 22 includes a plurality of openings 26 along its length. A support in the form of a rail pin 27 is shown. The lowest pin 27 is placed and supported in contact with the arm 25. FIG. Although 2a-2f shows only one support configuration, it should be understood that in practice there will be multiple brackets supporting the scaffold assembly over a substantial area inside and outside the construct. It will be apparent to those skilled in the art that the term construction can refer to a completed building or a building under construction. The scaffold system of the present invention is also applicable to buildings and construction work, but can also be used in connection with large-scale structures such as ships, dams, monuments, pylons, and the like. In fact, wherever known systems can be used, the system of the present invention can also be applied. Furthermore, the “drag and drop” nature of the present invention allows access to a variety of difficult building arrangements such as, for example, steps at the building level, or cantilever beams.

  The order in which the scaffold assembly 2 is moved and repositioned is shown in FIG. Description will be made with reference to 2a to 2f. A means (not shown) for raising the assembly 2 is attached to the assembly 2 and the assembly is raised to the next level of construction work. The brackets can be installed in any position in the construct that provides a convenient location for supporting the assembly, but each pin 27 is located below the next higher bracket arm 25, preferably next to the construct. It is made to engage at the level. During the raising operation, the pin 27 contacts the outer end of the arm as it is continuously raised upward, causing the arm 25 to pivot about a pivot point at the inward end of the arm 25. Thereby, the arm allows the support of the elongate member 22, ie the pin 27, to pass continuously upwards (see FIG. 2d in FIG. 2). FIG. As shown in 2e, when the pin 27 passes the farthest point of the outwardly facing end of the arm, the arm returns to its original horizontal position by gravity. FIG. The assembly is then lowered so that the pin 27 rests on the outward end of the arm 25, as shown at 2f. The arm does not pivot below its original horizontal position due to stop means (not shown). Thereby, each bracket 25 bears part of the weight of the elongate member 22, and thus the entire assembly. Thus, the assembly is repositioned to a new level higher than previously (as shown in FIG. 1d in FIG. 1). FIG. 2a to 2f is attached to the bracket shown in FIG. 3a and FIG. It will be described with reference to 3b.

  FIG. 3a shows a bracket according to an embodiment of the present invention, which has arm support means inserted between a pair of pivotally mounted opposing cooperating jaws 32a, 32b.

  FIG. 3b shows a particular embodiment of the bracket 23 for holding a part of the scaffold assembly of the system according to the invention. The bracket 35 shown is configured to mount to the construct via the back plate 36. The bracket includes two pairs of cooperating pivotable arms 32a, 32b and 33a (not shown), 33b. The uppermost arm set 32a, 32b is shown in the released, unlocked position, while the lowermost arm set 33a, 33b is shown in the closed holding position. Each pivotable arm includes a slot for engaging the flange portion of the longitudinal upright elongated member 31 of the scaffold assembly. The elongate member 31 shown includes a pair of U-shaped beams joined in a spaced relationship by a joining plate 35. However, it is envisioned that various other cross-section beams, such as H or I beams, can be used. For example, FIG. Support means 39 such as the arms 25 of 2a to 2f are inserted between the two U channel members 34a and 34b of the elongated member 31. The support is shown in the form of pins 44 inserted through aligned openings in the two channels 34a, 34b. The pin 44 is mounted on the arm 23 and supported by the arm 39, thereby supporting the elongated member 31 of the assembly 2. The additional pin 38 provides supplemental support in the event of a failure of the first pin 44. Thereby, the arm and pin configuration provides a convenient one-way valve or ratchet mechanism for supporting the assembly. The arm 39 includes a receiving bracket 43 towards its outer end, which is aligned to receive the pin 44 during positioning of the elongate member 31. The receiving bracket 43 helps guide the pins 44 into place during assembly disassembly or positioning. FIG. As shown in FIG. 3b, the receiving bracket 43 has a flared or flanged open end to assist in guiding the pin 44 of the member 31 to the proper position on the support arm 39. Yes. This ensures that the assembly is in the correct position and that the pivotable arm is clamped around the corresponding flange of the elongate member 31. Such a receiving bracket helps to mitigate the risk of the assembly tilting in the direction toward and away from the building due to the cantilever effect. If this tilt is very large, the pivotable arm cannot be held in place.

  During installation of the assembly to the construct, the pivotable arm pairs 32a, 32b and 33a, 33b are released and the elongated member is inserted between the channel rails 34a, 34b (25, FIG. 2a in FIG. 2). It is possible to be positioned with respect to the bracket 30 having). It will be appreciated that the scaffold system includes a plurality of such brackets 30 and thus this operation is repeated at a plurality of positions during installation of the assembly 2 to each bracket 30. When the assembly 2 is positioned relative to the bracket 30, the pivotable arm is pivoted to engage the flange on each side of the elongate rail 31. In the example shown in FIG. 3, each pivotable arm pivots on a bolt 37 through a portion of the bracket 30. Thus, it will be apparent to those skilled in the art that the scaffold assembly 2 cannot be disengaged from the bracket during the raising / lowering operation due to the holding means of each bracket 23 that holds the assembly 2. Thus, the modular scaffold assembly 2 can be “dragged” to the next required construction level of the construction and lowered to the support pins 44 until the entire assembly 2 is supported at a higher level. Thus, there is no waiting for favorable wind / weather or time delays in the assembly of expensive and complex hydraulic jack / ram systems. In addition, the assembly can include a high-strength wire mesh cover, a high-load safety net, a metal deck, a metal footrest, a lifting ladder, and a waste platform so that work can be performed smoothly, safely and efficiently. Enable.

  While particular embodiments of the present invention have been described herein, it will be apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit and scope of the invention. .
