Definitions

  • the invention relates to an assembly of a preceding-guardrail holder for a scaffolding system and a guardrail, and a method for arranging the guardrail on the scaffolding system using the preceding-guardrail holder.
  • Scaffolding systems are used in construction and the industry to work at places that cannot be reached from the ground.
  • two scaffold types can be distinguished, viz. system scaffolds and frame scaffolds.
  • System scaffolds comprise metal scaffold tubes, and scaffold couplings between these tubes.
  • the space that is formed by four standards, four transverse ledgers and four longitudinal ledgers is called a scaffold bay.
  • scaffold frames which are mutually connected with each other by floor parts.
  • Each scaffold frame comprises two standards which are mutually fixedly connected with each other by at least one transverse ledger.
  • Building up a scaffold bay proceeds in broad outline as follows. First, two vertical scaffold frames are placed at a distance from each other. The scaffold frames are connected at a particular height by means of floors. The assembly of two frame parts and the floors connecting these frame parts is called a scaffold bay.
  • braces may be fitted between the standards and ledgers.
  • a guardrail may be mounted between the standards.
  • the guardrail ensures that a person cannot fall off the floor parts.
  • a toe board may be mounted, which ensures that things on the floor cannot fall off but are held back by the toe board.
  • GB 1,051,164 discloses a coupling ("joint") for connecting a diagonal brace to an upright of a frame scaffold.
  • the joint comprises a joint body which is secured to an upright of a frame scaffold.
  • the diagonal brace is provided at each end with a connecting lug provided with a hole.
  • the joint body is provided with an opening for receiving the connecting lug of the brace.
  • the joint body is further provided with a locking pin slidably mounted in the body and arranged to be inserted through an aperture in the connecting lug of the brace when the brace is coupled to the joint body and whereby the brace is hence secured to the upright.
  • the connection between the joint body and the brace is such that the brace is pivotable around an axis which extends parallel to an axis of the upright to which the joint body is secured.
  • US 3 360 287 A shows a coupling for coupling ledgers or diagonal braces to the uprights of a scaffold.
  • the coupling comprises two pins placed one above the other and which are attached to an upright.
  • the ledgers or diagonal braces are provided at both ends with flat connecting lugs.
  • each flat connecting lug is provided with a slot or hole through which the pins of the coupling can be slipped.
  • the coupling is further provided with a locking element which hinders the ledgers or diagonal braces being able to fall off the coupling, which would result in failure of the scaffolding system.
  • a scaffolding system with a guardrail is for instance known from DE 101 12 369 A1 .
  • a guardrail 14 having at both ends fastening hooks for attachment to a standard of the scaffold frame.
  • a guardrail has the disadvantage that a floor level still unprotected at that moment needs to be entered to be able to mount this guardrail. If no additional provisions and/or means are used, this may be unsafe and in many cases this is also prohibited nowadays. Accordingly, there exists in the market a need for a so-called preceding guardrail.
  • a preceding guardrail is herein understood to be a temporary guardrail which can be placed above a protected floor level to protect an as yet unprotected floor before it is entered. Such a preceding guardrail can be mounted before the scaffold frame has been built up at the level of the preceding guardrail.
  • the firm Layher offers the Advance Guardrail (AGR) system.
  • AGR Advance Guardrail
  • This system consists of two telescopic preceding-guardrail posts and an advanced preceding guardrail. Via an ingenious system the advanced preceding guardrail is mounted to the telescopic preceding-guardrail posts.
  • These preceding-guardrail posts can be mounted, from a particular floor level protected with a preceding guardrail, at the height of an upper, still unprotected floor level and form a temporary preceding guardrail there. After the advanced preceding guardrail has been arranged, the upper floor level can be safely entered to arrange a permanent guardrail there.
  • the disadvantage of this system is that deviating preceding guardrails have to be purchased, which can only be used for the temporary system and which cannot be used further.
  • the object of this invention is to provide an assembly for arranging a temporary preceding guardrail on a scaffolding system, in which a preceding-guardrail holder can be used for placing a temporary preceding guardrail on an upper, unprotected floor level.
  • the invention provides to that end an assembly comprising a preceding-guardrail holder for a scaffolding system comprising standards, ledgers and substantially tube-shaped guardrails according to claim 1. More particularly, the preceding-guardrail holder is configured for cooperation with the guardrails of the scaffolding system.
  • Each guardrail is provided at a longitudinal end thereof with a fastening hook which has a curvature around a curvature axis which is perpendicular to a longitudinal axis of the guardrail.
  • the fastening hook is provided on a radial inner side thereof with a recess, while the distance of the recess to a point on a radial outer side of the fastening hook gradually increases from a first point on the radial outer side to a second point on the radial outer side of the fastening hook, with the second point being more remote from a center of the guardrail than the first point.
  • Such guardrails are already known. An example is the already mentioned guardrail 14 of DE 101 12 369 A1 .
  • the preceding-guardrail holder is provided with a mounting plate and with a retaining plate which extends substantially parallel to the mounting plate.
  • the mounting plate and the retaining plate are mutually connected by a first and a second cross connection element extending perpendicular to the mounting plate and retaining plate.
  • the two cross connection elements are mutually spaced apart and together bound a fastening hook receiving space for receiving the fastening hook of a first guardrail of the above-mentioned guardrails in the fastening hook receiving space.
  • the distance between the first and the second cross connection element is such that, if the fastening hook is received in the fastening hook receiving space and the first guardrail is not supported otherwise, the recess on the radial inner side of the fastening hook rests on the first cross connection element, and the radial outer side of the fastening hook abuts against the second cross connection element, as a result of which the first guardrail is wholly supported by the single preceding-guardrail holder.
  • the preceding-guardrail holder Due to this construction of the preceding-guardrail holder, it is possible to insert the fastening hook of the guardrail in the fastening hook receiving space of the preceding-guardrail holder, and to allow the guardrail to be supported by the preceding-guardrail holder.
  • the preceding-guardrail holder then hangs, as it were, by one end from the preceding-guardrail holder. This makes it possible to place the guardrail from below in a preceding-guardrail holder that is above an as yet unprotected floor level.
  • the preceding-guardrail holder is mounted on a temporary preceding-guardrail post which can be temporarily mounted to a standard.
  • the guardrail can be hung by one end in the preceding-guardrail holder.
  • the free end of the guardrail that is, the guardrail end whose fastening hook has not yet been fitted in a preceding-guardrail holder, is hanging down and can be handled from the lower floor level.
  • a second preceding-guardrail holder can be attached, which is mounted, for instance, to a second temporary preceding-guardrail post. By moving up this second temporary preceding-guardrail post and securing it to the scaffold frame, the upper floor level is protected by the guardrail, which thereby functions as preceding guardrail.
  • the preceding-guardrail holder in this way provides an elegant solution for arranging a temporary preceding-guardrail on an upper floor level.
  • This solution makes use of known guardrails, which are typically available on a building site. Accordingly, no new, specialized preceding-guardrails need to be purchased, while safety during arranging is guaranteed.
  • Arranging of the guardrail can simply proceed by hooking the fastening hook into the fastening hook receiving space. This can be done by a single person.
  • the invention provides an assembly according to claim 1 for arranging a temporary preceding guardrail on a scaffolding system comprising standards, ledgers and substantially tube-shaped preceding guardrails. More particularly, the invention provides an assembly comprising a guardrail and a first preceding-guardrail holder.
  • the guardrail is provided at a first longitudinal end thereof with a first fastening hook which has a curvature around a first curvature axis which is perpendicular to a longitudinal axis of the guardrail.
  • the first fastening hook is provided with a recess on a radial inner side. The distance of the recess to a point on a radial outer side of the first fastening hook gradually increases from a first point on the radial outer side to a second point on the radial outer side of the first fastening hook, with the second point being more remote from a center of the guardrail than the first point.
  • the guardrail may be provided at a second longitudinal end with a second fastening hook which has a curvature around a second curvature axis which is parallel to the first curvature axis, with the second longitudinal end located opposite the first longitudinal end of the guardrail.
  • the curvature of the second fastening hook may be opposite to the curvature of the first fastening hook.
  • the second fastening hook may, just like the first fastening hook, be provided on a radial inner side thereof with a recess, while the distance of the recess to a point on a radial outer side of the second fastening hook gradually increases from a first point on the radial outer side to a second point on the radial outer side of the second fastening hook, while the second point is more remote from a center of the guardrail than the first point.
  • the assembly may further be provided with a second preceding-guardrail holder, with a first preceding-guardrail post and with a second preceding-guardrail post.
  • the first preceding-guardrail post may, on or near an upper side, be provided with the first preceding-guardrail holder, and at a lower side be configured to be supported by a bracket of the scaffolding system, or a temporary bracket on the scaffolding system.
  • the second preceding-guardrail post may, on or near an upper side, be provided with the second preceding-guardrail holder, and at a lower side be configured to be supported by a bracket of the scaffolding system, or a temporary bracket on the scaffolding system.
  • the first preceding-guardrail post can be mounted to the scaffold frame, so that the upper side of the first preceding-guardrail post is located above an upper, unprotected floor level.
  • the first fastening hook of the guardrail can be received in the fastening hook receiving space of the first preceding-guardrail holder.
  • the second preceding-guardrail holder can then be attached to the second fastening hook, by inserting the second fastening hook into the fastening hook receiving space of the second preceding-guardrail holder.
  • the guardrail offers a protection for the respective floor level.
  • the assembly therefore provides a solution for arranging a temporary preceding guardrail on an upper floor level, utilizing known guardrails.
  • the invention further provides a scaffolding system comprising standards, ledgers, and the assembly according to the invention.
  • the invention further provides a method for arranging a temporary preceding guardrail according to claim 15. More particularly, the invention provides a method for arranging a temporary preceding guardrail on a scaffold, the method comprising:
  • the invention provides an assembly comprising a preceding-guardrail holder 10 for a scaffolding system comprising standards, ledgers and substantially tube-shaped guardrails 12, 14.
  • the preceding-guardrail holder 10 is configured for cooperation with the guardrails 12, 14 of the scaffolding system.
  • Each guardrail 12, 14 is provided at a longitudinal end with a fastening hook 16 which has a curvature around a curvature axis 20 which is perpendicular to a longitudinal axis 22 of the guardrail 12, 14.
  • the fastening hook 16 is provided on a radial inner side 24 thereof with a recess 28, while the distance of the recess 28 to a point on a radial outer side 26 of the fastening hook 16 gradually increases from a first point 30 on the radial outer side 26 to a second point 32 on the radial outer side 26 of the fastening hook 16, with the second point 32 being more remote from a center of the guardrail 12, 14 than the first point 30.
  • the preceding-guardrail holder 10 is provided with a mounting plate 34 and a retaining plate 36 which extends substantially parallel to the mounting plate 34.
  • the mounting plate 34 and the retaining plate 36 are mutually connected by a first and a second cross connection element 38, 40, both extending perpendicular to the mounting plate 34 and retaining plate 36.
  • the two cross connection elements 38, 40 are mutually spaced apart, and together bound a fastening hook receiving space 42 for receiving the fastening hook 16 of a first guardrail 12 of the above-mentioned guardrails 12, 14 in the fastening hook receiving space 42.
  • the distance between the first and the second cross connection element 38, 40 is such that if the fastening hook 16 is received in the fastening hook receiving space 42, and the first guardrail 12 is not supported otherwise, the recess 28 on the radial inner side 24 of the fastening hook 16 rests on the first cross connection element 38 and the radial outer side 26 of the fastening hook 16 abuts against the second cross connection element 40, as a result of which the first guardrail 12 is supported wholly by the single preceding-guardrail holder 10.
  • the guardrail 12, 14 with fastening hook 16 is already known.
  • An example is the already mentioned guardrail 14 of DE 101 12 369 A1 .
  • the invention merely concerns the assembly comprising additionally the preceding-guardrail holder 10 which is configured for cooperation with this, known, guardrail 12, 14.
  • the other effects and advantages of the preceding-guardrail holder 10 have already been described in the summary and these effects and advantages are understood to be inserted here by citation.
  • the distance between the first and the second cross connection element 38, 40 is such that if the first guardrail 12 is merely supported by the preceding-guardrail holder 10, the first guardrail 12 makes an angle of 20° to 70° with the horizontal, preferably between 40° and 50°, more preferably about 45°.
  • the first guardrail 12 will tend to hang down obliquely.
  • the guardrail 12 can be simply attached at a higher level and be engaged from a lower level.
  • the preceding-guardrail holder 10 is configured for cooperation with a second guardrail 14 of the above-mentioned guardrails 12, 14. If the first guardrail 12 extends on a first side of the preceding-guardrail holder 10 and the recess 28 of the first guardrail 12 engages the first cross connection element 38, the second guardrail 14 extends on a second side of the preceding-guardrail holder 10 and the recess 28 of the second guardrail 14 engages the second cross connection element 40. The second side of the preceding-guardrail holder 10 is located opposite the first side of the preceding-guardrail holder 10. The first cross connection element 38 and the second cross connection element 40 may be placed at a same height.
  • the fastening hook receiving space 42 becomes symmetrical, as it were. In that case, it makes no difference for the guardrails 12, 14 anymore from which side they are attached to the preceding-guardrail holder 10. In this way, the preceding-guardrail holder 10 can be used to attach a guardrail 12, 14 on both sides. Such a preceding-guardrail holder 10 may for instance be used in a continuous guardrail along a scaffold frame.
  • the first and the second cross connection element 38, 40 are perpendicular to the longitudinal direction of the first guardrail 12, parallel to the curvature axis 20. Such an orientation provides for a stable, reliable attachment of the first guardrail 12 to the preceding-guardrail holder 10.
  • the fastening hook 16 is a plate-shaped hook and the distance between the mounting plate 34 and the retaining plate 36 is such that the plate-shaped hook is fittingly received in the fastening hook receiving space 42.
  • a plate-shaped hook has for instance a minor cross section in the direction of its curvature axis, whereas a cross section radial to the curvature axis is many times greater.
  • a fastening hook receiving space 42 tailored to this shape has as an effect that the first guardrail 12 cannot turn around a tangent of the fastening hook 16. Accordingly, therefore, the guardrail 12 will not move out of a vertical plane that extends parallel to the longitudinal ledgers of the scaffolding system and will be pivotable in that vertical plane only from the initial oblique position to the eventual horizontal position.
  • the preceding-guardrail holder 10 is further provided with a first fastening protection 44 above the fastening hook receiving space 42.
  • the fastening protection 44 is configured for hindering a taking-out of the fastening hook 16 of the first guardrail 12 out of the fastening hook receiving space 42 other than partly by a turning of the first guardrail 12 around the curvature axis 20.
  • the first fastening protection 46 may also be configured for hindering a taking-out of the fastening hook 16 of the second guardrail 14 out of the fastening hook receiving space 42 other than partly by a turning of the second guardrail 14 around the curvature axis 20.
  • the fastening hook 16 By lifting it a little bit, the fastening hook 16, by turning around the curvature axis 20 or an axis parallel thereto, can be taken out of the fastening hook receiving space 42.
  • the fastening protection 44 is so positioned that this movement is not hindered.
  • An example of this is shown in Figure 4 .
  • the blocking of this movement is of importance if the first guardrail 12 is for instance hanging horizontally, for instance because it is supported at a longitudinal end opposite the longitudinal end that is provided with the fastening hook 16. This is for instance the case if the first guardrail is in use and hence extends horizontally.
  • the fastening protection then ensures that the first guardrail 12 cannot be taken or knocked out of the preceding-guardrail holder 10.
  • the first fastening protection 44 can have a first position in which the first fastening protection 44 hinders a taking-out of the fastening hook 16 out of the fastening hook receiving space 42 other than partly by a turning of the first guardrail 12 around the curvature axis 20.
  • the first fastening protection 44 can additionally have a second position in which the first fastening protection 44 allows taking-out of the fastening hook 16 partly by a translation of the first guardrail 12.
  • An example of such a first fastening protection 44 is the tipping closure shown in the figures. In the example of Figures 2 , 3, and 4 , the first fastening protection 44 is in the first position.
  • the first fastening protection 44 hinders a taking-out of the first guardrail 12 by translation.
  • the first fastening protection 44 is in the second position. In this second position it is possible to have the first guardrail 12 make a small turning around the longitudinal axis 22 and then by a translation move it substantially upwards, as a result of which the fastening hook 16 is taken out of the fastening hook receiving space 42 of the preceding-guardrail holder 10. A turning of a few degrees is sufficient then. A turning of for example 5° is sufficient in the example shown to be able to take the first guardrail 10 out of the preceding-guardrail holder 10.
  • the translation may be oriented a little obliquely upward to prevent a collision with the first fastening protection 44. If the first fastening protection 44 is also configured for hindering a taking-out of the fastening hook 16 of the second guardrail 14 out of the fastening hook receiving space 42 other than partly by a turning of the second guardrail 14 around the curvature axis 20, then all that has been described above for the first fastening protection 44 in relation to the first guardrail 12 also holds for the first fastening protection 44 in relation to the second guardrail 14.
  • the preceding-guardrail holder 10 with a second fastening protection 46.
  • This second fastening protection 46 is provided above the fastening hook receiving space 42 and is configured for hindering a taking-out of the fastening hook 16 of the second guardrail 14 out of the fastening hook receiving space 42 other than partly by a turning of the second guardrail 14 around the curvature axis 20.
  • this second fastening protection 46 may, analogously to the first fastening protection 44, have a first position in which the second fastening protection 46 hinders a taking-out of the fastening hook 16 of the second guardrail 14 out of the fastening hook receiving space 42 other than partly by a turning of the second guardrail 14 around the curvature axis 20. Also, the second fastening protection 46 may further have a second position in which the second fastening protection 46 allows taking-out of the fastening hook 16 partly by a translation of the second guardrail 14.
  • the operation of the second fastening protection 46 is analogous to that of the above-described first fastening protection 44. Also the second fastening protection 46 may be, for example, the tipping closure shown in the figures.
