Definitions

  • the invention relates to a front side railing for securing a front side of a walk-in scaffolding, in particular when constructing this walk-in scaffolding according to claim 1, and a scaffold with such a front side railing according to patent claim 8.
  • the invention further relates to a method for securing the front side of a scaffolding against people falling when assembling the scaffolding according to claim 13.
  • Scaffolding is used in the construction sector for various tasks. Facade scaffolding is used to design the exterior surfaces of buildings, for example to paint them. In civil engineering, scaffolding or shoring is used to bring a wide variety of building parts into position and hold them there. Such building parts can be, for example, prefabricated concrete parts, steel beams or steel structures. Furthermore, elements required for the construction of structures such as temporary structures or formwork with supporting scaffolding can be positioned. Finally, scaffolding is also used in the service or inspection area, for example to bring workers safely to the parts of the system that need to be overhauled in large process engineering plants, such as refineries. In general, the basic requirements for scaffolding are that they must be easy to transport and easy to assemble. The scaffolding is usually constructed from bottom to top.
  • next higher floor is built from the scaffolding floor below.
  • next higher floor is under construction, there is an increased risk of accidents due to falls, as the next higher floor is not yet completely built and does not have all the necessary safety precautions against falls.
  • the most necessary safety precautions must be installed from the floor below to the next floor before workers enter and complete the next floor.
  • scaffolding-mounted safety precautions workers can also be protected when erecting the next higher floor by wearing personal protective equipment while working on the still unsecured, next higher floor.
  • personal protective equipment is expensive and takes time to put on and connect to the scaffolding.
  • a safety railing which can be mounted from one floor to the front of the next higher floor of a scaffolding. This After assembly, the safety railing is arranged between two vertical scaffolding elements on the next higher floor. The disadvantage of this railing is that if this railing is to be removed again on the next higher garage, there is no protection against falling on the front side.
  • a railing for the front sides of scaffolding is known, which is attached to horizontal scaffolding elements of the existing scaffolding levels using hooks.
  • a movable locking mechanism is provided, which must be activated when installing and dismantling the railing on the scaffolding.
  • the handling of this railing is complicated and the length dimension of the railing is large, making it bulky to transport.
  • This object of the invention is achieved by a front side railing for securing a front side of a walk-in scaffolding, according to claim 1.
  • the safety bracket of a front side railing effectively prevents workers or other people who are on the corresponding level of the scaffolding from falling down by blocking the open side on the front side of a scaffolding.
  • the safety bracket has two sections, the protective section arranged at the top when installed and the fastening section arranged underneath.
  • the protective section is constructed in such a way that it effectively blocks the open side of the scaffolding.
  • a U-shaped design has proven to be particularly suitable for this function, which is additionally provided with one or more holding elements within the U and is therefore closed.
  • the fastening section is used to fasten the front railing to the scaffolding.
  • the fastening section has at least two fastening elements.
  • the fastening elements are arranged at a distance from one another, this distance conveniently corresponding approximately to the width of the scaffolding or the distance between two vertically extending elements on the front side of the scaffolding.
  • the fastening elements define a fastening plane with one of their surfaces.
  • the safety bracket of the end railing according to the invention has a side which points towards this scaffolding during assembly and an opposite side which points away from the scaffolding during assembly.
  • the outermost surfaces of the fasteners on the side facing the scaffolding during assembly define the fastening plane.
  • the attachment level therefore represents the the outermost level of the safety bracket, which points towards the scaffolding when mounted on the scaffolding.
  • the fastening level is an imaginary level that serves to define further features of the front railing according to the invention.
  • An end railing according to the invention also has two vertical pins which are intended to be connected to the scaffolding and thus serve to attach the end railing to the part of the scaffolding that has already been constructed.
  • the vertical pins run in the vertical direction and are arranged at a distance from the adjacent fastening elements.
  • the connections between fastening elements and vertical pins form the fastening areas that are arranged between fastening elements and vertical pins.
  • the vertical pins are inserted into recesses that are usually horizontally oriented. After the vertical pins have been inserted into the recesses, the fastening areas rest on parts of the already constructed scaffolding.
  • the vertical pins are arranged in the lower half of the fastening section when installed.
  • the vertical pins end flush with the lower ends of the fastening elements. Due to this arrangement of the vertical pins in the lower area of the safety bracket, the end railing has a compact vertical dimension, which makes it easy to transport and easy to handle.
  • the vertical pins of a front railing according to the invention are intended to be inserted into exceptions which are attached to the upper end of the already constructed part of the scaffolding. Railings from the prior art are partially attached to scaffolding elements that are arranged further down than the upper end of the existing floor. As a result, such railings from the prior art must be of larger dimensions in the vertical direction, which entails disadvantages due to a higher weight and larger dimensions of these railings.
  • the vertical pins are arranged outside the fastening plane and are located on the side of the fastening plane that is oriented towards the scaffolding in the assembled state. Because the vertical pins, which serve to connect to the scaffolding, are arranged outside the fastening plane, the securing bracket in the assembled state is at a distance from vertical elements of the scaffolding that already exist or are yet to be assembled. The safety bracket is therefore arranged outside the other scaffolding elements. This brings a decisive advantage This arrangement outside means that the space between two adjacent, vertical scaffolding elements on the next higher floor is free. As a result, a further, permanently installed front railing can be arranged in this room while the front side railing according to the invention protects this opening against falling.
  • a front railing according to the invention thus combines proper securing of the front side with acceptance by the people who are entrusted with the construction of the scaffolding.
  • the end railing comprises at least one guide, which is intended to secure the end railing against tilting relative to vertically extending elements of the scaffolding at least in one spatial direction, the guide being firmly connected to the protective section and having at least two legs spaced apart from one another in the horizontal direction, wherein the guide protrudes from the protective section in the direction from which the fastening plane points towards the scaffolding when mounted on the scaffolding.
  • at least one guide is provided which, in addition to the previously described vertical pins, establishes a further connection between the end railing and the scaffolding.
  • the front side railing is connected to the scaffolding in two places at different vertical heights. This provides improved protection against workers falling.
  • the leadership occurs in connection with vertical elements of the scaffolding, in particular with vertical supports, which belong to the next higher level of the scaffolding that is under construction.
  • the guide secures the front side railing against tilting at least in one direction.
  • the guide has two legs spaced apart from one another, which can encompass vertically extending scaffolding elements.
  • the guide like the vertical pins, also protrudes from the mounting plane and is therefore arranged outside the securing bracket.
  • This also results in the second connection point of the front side railing, namely between the guide and vertically extending scaffolding elements, that the safety bracket is positioned outside the front side of the scaffolding when the front side railing is attached to the scaffolding.
  • This also ensures in the area of the guide that the space between two vertical elements of the scaffolding, in particular vertical posts, remains free in order to install a permanent standard railing on the front side of the scaffolding in addition to the front side railing.
  • the proposal advantageously provides that the two legs of the guide have different shapes.
  • the two legs of a guide are shaped differently. This means that the guide can be easily and safely mounted on the scaffolding without having any moving parts.
  • a first leg has a hook-shaped functional area and a second leg has a flat functional area, the functional areas being intended to interact with elements of the framework.
  • the functional areas are the areas of the legs that come into contact with other scaffold elements.
  • a first leg has a hook-shaped functional area which is intended to at least partially surround a vertically extending scaffolding element, in particular a vertical handle. This hook-shaped area is designed in such a way that it engages behind a vertical handle when the front railing is assembled, so that the front railing cannot be accidentally removed from the scaffolding.
  • the second leg is flat Functional area and forms a counter bearing to the leg with the hook-shaped functional area. When assembled, the leg with the flat functional area does not reach behind the vertical scaffolding elements.
  • At least two guides are provided, which are arranged horizontally spaced apart from one another on the protective section when mounted on the scaffolding.
  • two guides are provided, each of which is conveniently arranged on one leg of the U-shaped safety bracket in the area of the protective section.
  • the legs that have a flat functional area are at a smaller horizontal distance from one another than the legs that have a hook-shaped functional area.
  • the legs with the flat functional area are arranged further inside than the legs with the hook-shaped functional area on the protective section.
  • a leg with a flat functional area of a first guide is arranged above a leg with a hook-shaped functional area and, in a second guide spaced horizontally from the first guide, a leg with a flat functional area is arranged below a leg is arranged in a hook-shaped functional area.
  • the legs of the two guides are arranged differently in the vertical direction. On one side there is a leg with a hook-shaped functional area above a leg with a flat functional area. For the guide on the opposite side, the arrangement is exactly the other way around.
  • This embodiment makes it possible to assemble or disassemble the front railing by a pivoting movement between two vertical supports, without moving parts are required.
  • the legs with the hook-shaped functional area engage behind the vertical posts and thus secure the front railing.
  • the end railing is then rotated for dismantling about an axis perpendicular to the fastening plane until the two legs with the flat functional area abut the vertical posts, then in this attached state the undercut of the legs with the hook-shaped functional areas to the vertical posts is eliminated and the end railing can be removed from the scaffolding.
  • This special arrangement of the different legs means that the end railing can be separated from the vertically extending scaffolding elements or connected to them in a form-fitting manner by means of a rotary movement.
  • the two legs with a hook-shaped functional area on their side facing away from the protective area have a clear width relative to one another, into which vertically extending elements of the framework can be inserted, this clear width being smaller than the external distance between two adjacent, vertically extending elements of the scaffolding is.
  • the scaffolding is secured in that the end regions of the legs with the hook-shaped functional area have a clear width to one another that is smaller than the external distance between two adjacent vertical posts of the scaffolding.
  • the effective distance between the end regions of these legs can be increased in the horizontal direction by rotating the end railing, which means that in this twisted state the vertically extending scaffolding elements can be inserted between the legs is possible with the hook-shaped functional area. If the front railing is then rotated back to its normal alignment, the effective distance between the two legs is reduced again to the clear width and the front side railing is positively connected to the vertical scaffolding elements.
  • the two legs with a flat functional area have a leg distance on their side facing away from the protective area to each other, which is smaller than the internal distance between two adjacent, vertically extending elements of the framework.
  • the two legs with the flat functional area are positioned relative to one another in such a way that they can be inserted with play between two mutually adjacent vertical stems.
  • the legs with a flat functional area which are offset from one another in the vertical direction, serve as a stop for this rotational movement during the previously described rotational movement of the end railing, which is used for assembly and disassembly.
  • the two legs with the flat functional area prevent the end railing mounted on the scaffold from tilting parallel to the fastening level.
  • the surfaces of the protective section which are oriented towards the scaffold when mounted on the scaffold, are arranged in the fastening plane.
  • the entire safety bracket is designed to be flat.
  • the surfaces of the protective section oriented towards the framework also lie in the fastening plane, which is defined by the surfaces of the fastening elements of the fastening section facing the framework.
  • a flat safety bar is particularly advantageous for storage.
  • the protective section and the fastening section can also be arranged offset from one another, in which case the surface of the protective section facing the framework is not in the fastening plane.
  • the proposal advantageously provides that the entire front railing is designed to be rigid and in particular has no moving parts. It is particularly advantageous that the front railing is rigid. This means that the front railing is robust and reliable even in harsh environmental conditions on a construction site. In the case of railings with moving parts, as are known from the prior art, these moving parts can become dirty or corrode and are then no longer functional. In this case, such railings can pose a major safety risk if the railings no longer function as intended. With a rigid front railing, such wear and tear on moving parts cannot occur, which is very advantageous for longevity and safe function.
  • the vertical pins are essentially vertically oriented when mounted on the scaffolding and are rod-shaped.
  • the vertical pins are straight, in particular rod-shaped.
  • Rod-shaped base materials are available in many different sizes and strengths, making the front railing easy to manufacture.
  • By arranging the vertical pins vertically they can be inserted particularly easily into recesses on the scaffolding.
  • the vertical pins can also be designed to be curved or curved. With such curved vertical pins, the fastening element can be saved and the vertical pins can be connected directly to the fastening elements.
