Scaffold with an automatic installation characteristic

Abstract

An automatic scaffold for reaching buildings during construction, repair, dyeing, coating, and maintenance. The automatic scaffold includes a scaffold module which has a stack of module layers. Movable columns open the scaffold modules by a drive unit so as to generate a distance between the module layers, wherein the distance is approximately of 2-meter height in which one person can comfortably work, and wherein the movable columns are respectively an outer carrier column which carries the scaffold module upwardly with the movement generated by the drive unit, and an inner movable column which is located inside the outer carrier column and linked to the outer carrier column via a control rod of the drive unit. Each module layer has vertical and horizontal rods, a carrier plate, and guide elements for fixing the vertical rods to the carrier plate.

DETAILED DESCRIPTION OF THE INVENTION

(9) The automatic scaffold (100) of the present invention is suitable for reaching a building during construction, repair, dyeing, coating, and maintenance. The automatic scaffold (100) has a scaffold module (130) which includes module layers (131) that are superimposed, movable columns (110) which can be driven through a drive unit (116) so as to open a distance (A) between the module layers (131) for working, vertical and horizontal rods (119, 120) which are located between the module layers (131) within the distance (A), and guide elements (125) which are located on the carrier plates (118) for fixing the vertical carrier rods (119) thereto.

(10) The outer carrier columns (111) carry the scaffold modules (130) which are connected thereto upwards in the s-direction with the movement generated through the drive unit (116). The drive unit (116) is a motor. Alternatively, the drive unit (116) is a piston with a hydraulic or a pneumatic system.

(11) The automatic scaffold (100) has a circular gear (117) which is set into rotational movement through the drive unit (116), and a control rod (115) which is connected to the circular gear (117), an inner movable column (114) onto which the control rod (115) is fixed and which is located inside a space (113) of the outer carrier column (111), centering elements (112) which have rollers (127) for the linear movement of the inner movable column (114) inside the outer carrier column (111), guide step sections (126) respectively formed on the guide elements (125), guide spaces (128) formed on the carrier plate (118) so that the guide elements (125) can be located thereinto, rod locating elements (124) for locating in a fixed manner the vertical, horizontal rods (119, 120, 121) onto the carrier plate (118), front covers (122) fixed on the module layers (131) of the scaffold module (130), and legs (129) located at the bottom of the vertical carrier rods (119) and fixed onto the floor.

(12) The working system of the automatic scaffold (100) is as follows. The system which is adjustable to the width measurements of the construction or building and which has multiple movable columns (110) can be carried either as a whole on a long vehicle or in parts thanks to its modular structure.

(13) In FIG. 5, a scaffold module (130) is shown which includes preferably 11 module layers (131) on preferably 4 movable columns (110). FIG. 5 shows an uninstalled view of the scaffold (100). In order to start the installation process automatically, the system can be directed through a control unit or a remote control (132). Each scaffold module (130) is carried upwards in the s-direction as a whole in a way that one module layer (131) stays at the bottom. After the module layer (131) denoted with A1 at the bottom has been left, the other scaffold modules (130) are carried completely in the s-direction in a way that the distance (A) is formed. The distance (A) is approximately of 2-meter height, in which one person can comfortably work. After the distance (A) has been formed, another module layer (131) denoted with A2 is left free, and all the other module layers (131) are lifted upwards. Later on, again another module layer (131) denoted with A3 is left free, thus the module layers (131) of the scaffold modules (130) are separated, and intermediate distances (A) are formed (See FIG. 1).

(14) It is the movable columns (110) which provides for the scaffold modules (130) to be carried and left in the s/s1 direction as a whole.

(15) The movable columns (110), on the other hand, provides opening/closing of the scaffold (100) as follows: The scaffold modules (130) are loaded to the outer carrier column (111). In other words, the entire load is carried by the outer carrier columns (111). However, the vertical descending and ascending movement is provided by the inner movable columns (114) for the outer carrier columns (111). Therefore, all the load of the system is on the inner movable column (114). The inner movable column (114) is located in the space (113) of the outer carrier column (111), and in that space (113) the system is provided with movement. The outer carrier column (111) is provided with vertical linear movement in the s/s1 directions through the control rod (115) fixed on the inner movable column (114), and the circular gear (117) driven by the motor on the outer carrier column (111). (See FIG. 6). Centering elements (112) are located in the space (113) of the outer carrier column (111) in order to provide that the movement is rigid and properly linear. The centering elements (112) have rollers (127) for making the movable columns (110) to proceed more easily.

(16) In FIG. 7, on the other hand, the scaffold module (130) is shown individually. The module layers (131) are located in superimposed positions. Guide elements (125) are bedded or centered between the module layers (131). The guide elements (125) located in the guide spaces (128) of the carrier plate (118) at the same time serve as bedding elements for the vertical carrier rods (119) between the module layers (131). The distance (A) is formed by means of the guide elements (125) and the vertical carrier rods (119). By using the rod locating elements (124), the horizontal and vertical rods (119, 120, 121) can be located on the carrier plate (118). (See FIG. 4). After the distance (A) has been formed, the horizontal and vertical rods (119, 120, 121) are attached to the guide elements (125) in a click-fit manner by the staff (See FIG. 2). The superimposition of the module layers (131) forming the scaffold module (130) is provided by the guide spaces (128) created on the carrier plates (118) and the guide elements (125) located within these spaces (128). The upper ends of the guide elements (125) have guide step sections (126) respectively, and the bottom ends of the guide elements (125) are fitted to the guide step sections (126) respectively, and thereby superimposed and closed. As the modular layers (131) are opened, vertical carrier rods (119) are fixed between the guide elements (125).

(17) The carrier plates (118) have one-piece structures. Preferably it is possible to produce them with modular multiple-piece structures. The vertical carrier rods (119) form a skeleton structure by being squeezed between the carrier plates (118). As the carrier plate (118) has a platform and a walking line, the walking path platform on any floor of the scaffold (100) according to the present invention cannot be separately removed. In order to remove a platform on an intermediate floor, all the system should be uninstalled from top to down.

(18) There are vertical and horizontal rods (119, 120, 121) in order to form a distance (A) between the module layers (131). These rods (119, 120, 121) are quickly installed by the staff, and thus a module layer (131) is obtained with a distance (A) for working. The passage from one module layer (131) to the other is provided by ladders (123). In order to move the movable columns (110), a motor serving as a drive unit (116) is used. However, instead of a motor, preferably manual use is possible. Also the movable columns (110) can be provided with the vertical linear movement through lifters with hydraulic or pneumatic systems.
