Definitions

  • the present invention refers to a provisional railing conceived to be installed during the construction of buildings, especially during the construction of the staircases, constituting a fundamental safety element to prevent persons in the vicinity from falling into empty space or onto floors below.
  • a safety railing constituted in a way such that it admits adaptation to any inclination of the framework of a staircase.
  • a railing of the type of those which are constituted by two pincer-like telescopic bodies, adjustable by means of an internal screw worked by a lever, so the elements that act as pinching arm in the assembly with respect to the framework have corresponding revolving clamps that facilitate the adaptation thereof to any inclination of the framework.
  • This type of railing has the fundamental inconvenience that, once installed, the upper clamp is located on the horizontal plane or tread of the step, hindering the work of finishing the same.
  • the lower clamp is positioned on the inclined plane which is delimited by the planking of the staircase on the underside thereof, hindering possible work to be carried out on this surface.
  • Another inconvenience detected in this type of railing is that the union between the railings and the battens which configure the safety railing is implemented by placing said battens in the L-shaped supports which the railings incorporate, without having any reliable means of fastening.
  • this safety railing is installed on a staircase, the battens will not be horizontal, since their ends will be resting in supports belonging to railings located at different heights, whereby the surface supporting said battens on each of the supports will not even be that corresponding to the width of said supports. For this reason it is considered that this fastening system is not the most appropriate in a safety railing, and even less so if it is going to be installed in a staircase under construction, since it does not guarantee the minimum level of safety required in this type of device.
  • the object of the present invention is to achieve an adequate railing for its provisional installation on any formwork during the construction of buildings, especially during the construction of the staircases, so that it constitutes a safety element to prevent persons moving in the vicinity from falling into empty space or onto floors below, even in the phase of finishing the surfaces delimited by said railing.
  • the railing disclosed has the advantage over the safety railings known up to now in that the system of anchoring the vertical posts bearing the horizontal protection is not fastened to the horizontal surface of the formwork, hindering in this way the work on this surface, but is instead fastened to the external vertical plane of said formwork.
  • the railing which is disclosed below is specially suitable for its installation during the construction of staircases, although the incorporation of an optional baseboard accessory adapts it for use as a protective element in lift shafts, on balconies and roofs during the construction of the building.
  • the provisional railing object of this invention consists basically of some supports which allow the fastening to the external vertical plane of the formwork of the vertical tubular stanchions, these vertical stanchions being the bearers of the horizontal protection, this assembly constituting a protector for the staircases which is easy to mount and to store.
  • the supports of this provisional railing are installed on the external ends of the framework of the staircase under construction, specifically in the plane perpendicular to that constituted by the tread of each step.
  • the fastening of two of the models of these supports is done with some screws, fixing them to the side of the staircase, while the fastening of the third support model is carried out by anchoring a piece in the concrete.
  • the first of the supports is formed by a fishplate basically rectangular and flat in shape, having a thickness such that it allows the easy anchoring thereof to the formwork of the staircase by means of screws, for which reason it has several drilled holes, usually two, for the correct screwing thereof.
  • the support is completed with a length of tube, termed the bearing tube, in which the vertical, tubular stanchions are inserted, as will be seen later.
  • the fishplate that constitutes the base of the supports has joined thereto a spacing tube the only function of which is to overcome all the projections produced by the actual construction.
  • the spacing tube is located between the fishplate and the bearing tube. The union between this fishplate and said spacing tube is carried out by welding, the spacing tube being positioned parallel to the fishplate so that the surface affected by the welding is as large as possible, guaranteeing thereby a correct join between the two elements.
  • this tube can be chosen according to the needs of each occasion, keeping in mind that the length thereof must never be greater than that of the fishplate and must not impede the screwing of the latter to the formwork, for which reason the holes drilled in the fishplate must always be accessible.
  • spacing tubes can be chosen of more or less diameter or thickness, so that the railing is installed more or less removed from the end of the formwork of the staircase. If it is considered unnecessary to separate the staircase, supports similar to those described will be installed, but without incorporating the spacing tube.
  • the union between the spacing tube and the bearer tube is also carried out by welding and, as in the previous case, they are located parallel to each other.
  • the bearer tube will be welded directly to the fishplate.
  • These bearer tubes have the purpose of holding the vertical tubular stanchions which are introduced in said bearer tubes.
  • the dimensions and form of the bearer tube have to be such that they allow the subsequent introduction of the vertical tubular stanchions, so that if the vertical tubular stanchion which is going to be installed has a rectangular section, the bearer tube will have this same section, the same if this section is round or any other section.
  • the length thereof it will usually be slightly less than that of the spacing tube to which it is welded, so that the greatest possible welding surface is achieved without impeding the fastening of the fishplate to the formwork.
  • the bearer tube has a system of anchoring by means of shackles, generally operated by means of a crank.
  • the support according to a second manner of embodiment of the invention consists basically of a tubular piece mounted horizontally with a second tubular piece joined to the first forming an L.
  • the join of this support to the formwork of the staircase is carried out by screwing a plate which is joined to the end free of the tubular piece.
  • the assembly proceeds of the vertical tubular stanchion, which is located on the second tubular piece of the support, said piece being inserted in the internal cavity of the stanchion.
  • a rod is passed through some lateral holes of the vertical tubular stanchion, which holes coincide with the through-holes made in the side faces of the second tubular piece of the support.
  • the third possible embodiment of the support differs substantially from the previous two, since in this case the union of the same one to the lateral formwork of the staircase is not carried out by screwing.
  • the support in this third embodiment has an anchor piece which, as its name indicates, is anchored in the concrete of the formwork of the staircase presenting its open face toward the exterior of said formwork.
  • said anchoring tube After welding an anchoring tube to the lower part of the front face of the vertical tubular stanchion, said anchoring tube is introduced on the anchor piece, being fastened thereto by shackles due to two gudgeon stops which said tube incorporates.
  • a rod is made to pass through the front holes of the vertical tubular stanchion, the end of said rod being introduced in an upper housing of the anchor piece.
  • This third manner of embodiment of the support also allows the spacing of the railing to be regulated with respect to the external end of the formwork of the staircase, having for this a spacing fishplate which is inserted between the front face of the vertical tubular stanchion and the open face of the anchor piece, limiting the penetration of the anchoring tube in said piece.
  • the vertical tubular stanchion can have diverse embodiments and dimensions, provided that these are appropriate for its correct fastening to the supports fixed to the external formwork of the staircase.
  • Each vertical tubular stanchion has at least one positioning and fastening element to allow the subsequent assembly of the horizontal protection which configures the actual protective railing.
  • These positioning and fastening elements will usually consist of a stepped fishplate fitted with an anchor system by means of shackles, it being possible to vary the number thereof as a function of the height of the vertical tubular stanchion or as a function of the number of horizontal protection elements to be installed on the provisional railing, configuring in this way more or less closed railings.
  • One of the additional advantages of the invention besides the fundamental one of not impeding the work to be carried out in the staircase under construction, is its great versatility and simplicity of assembly.
  • the tube welded to the vertical tubular stanchion brings the horizontal protection near to the staircase, in this way an adequate spacing is achieved in the lower area of the same, which is the working area, without the railing being thereby excessively removed from the staircase, which would impair its function as a safety element.
  • the fact that a same vertical tubular stanchion can be mounted in any one of the three possible supports implies an advantage as to provisioning and storage.
  • the only tool necessary is a drill to screw the fishplate of two of the possible embodiments of the supports to the formwork of the staircase, the remaining operations, such as fastening the vertical tubular stanchion to the bearer tube or that of the horizontal protection to the positioning and fastening element, can be carried out in a simple manner by hand.
  • FIG. 1 An example of embodiment of the invention can be seen therein which consists of a provisional railing (1) constituted basically by a number of supports (2) on which are installed the vertical tubular stanchions (3) which carry the horizontal protection elements (4), the number of these being variable according to that considered necessary in each application.
  • the supports (2) of said provisional railing (1) are installed on the external ends (5) of the framework of the staircase under construction, specifically on the plane perpendicular to that which constitutes the tread (6) of each step.
  • each of them is formed by a fishplate (8), a bearer tube (11) and an anchoring system (12) to hold the vertical tubular stanchion (3) associated with each support (2).
  • the support (2) includes a spacing tube (10) to overcome the projections produced by the actual construction, said tube being placed between the fishplate (8) and the bearer tube (11).
  • the fishplate (8) of the support (2) is basically rectangular and flat in shape, of a thickness such that its easy anchoring to the formwork of the staircase by means of screws (7) is allowed, for which reason it has several drilled holes (9), usually two, for the correct screwing thereof.
  • the fishplate (8) which constitutes the base of the supports (2) usually has a spacing tube (10) joined thereto the only function of which is that of overcoming all the projections produced by the actual construction.
  • the union between said fishplate (8) and said spacing tube (10) is implemented by welding, the spacing tube (10) being mounted parallel to the fishplate (8) so that the surface affected by the welding is as large as possible, assuring in this way a correct union between the two elements.
  • the union between the spacing tube (10) and the bearer tube (11) is also implemented by welding and, as in the previous case, they are mounted parallel to each other.
  • These bearer tubes (11) have the purpose of supporting the vertical tubular stanchions (3) which are introduced in said bearer tubes (11).
  • the bearer tube (11) has a system (12) of anchoring by means of shackles, generally operated by means of crank (13).
  • FIG 4 shows a second possible embodiment of the support (2) which forms part of the provisional railing (1) object of this invention.
  • This support (2) is formed by the union of a horizontal tubular piece (16) with a second tubular piece (17) perpendicular to the previous one, this union forming an L-shaped support.
  • a plate (18) is mounted which has several drill holes (9), so that it is fastened to the framework by screwing.
  • the vertical tubular stanchion (3) is mounted therein.
  • the assembly is carried out by introducing the second tubular piece (17) of the support (2) in the interior cavity of the stanchion.
  • a rod (21) is passed through the side holes (19) which the vertical tubular stanchion (3) has for this purpose, which holes coincide with the through-holes (20) of the second tubular piece (17) which constitutes this second support model (2).
  • supports (2) with tubular pieces (16) of different lengths allows the provisional railing (1) to be installed more or less removed from the external end of the framework (5).
  • the third possible embodiment of the support (2) differs substantially from the previous two, since in this case the union of the same to the external end of the framework (5) is not carried out by screwing.
  • the support (2) in this third embodiment has an anchor piece (22) which, as its name indicates, is anchored in the concrete of the formwork of the staircase, presenting its open face toward the exterior of said formwork. After welding an anchoring tube (23) to the front face of the vertical tubular stanchion (3), said anchoring tube (23) is inserted in the anchor piece (22), being fixed thereto by shackles due to two gudgeon stops (24) which said tube incorporates.
  • This third manner of embodiment of the support (2) also allows the spacing of the provisional railing (1) to be regulated with respect to the external end of the framework (5) of the staircase, having for this a spacing fishplate (26) which is inserted between the front face of the vertical tubular stanchion (3) and the open face of the anchor piece (22), limiting the penetration of the anchoring tube (23) in said piece.
  • each vertical tubular stanchion (3) can have diverse embodiments and dimensions, provided they are compatible with the support (2) installed in the formwork. As is appreciated in figure 2, each vertical tubular stanchion (3) has at least one positioning and fastening element (14) to allow the subsequent assembly of the horizontal protection elements (4) which configure the actual protective railing.
  • these positioning and fastening elements (14) will consist of a stepped fishplate (27) fitted with an anchoring system (12) by means of shackles which can be the same as that employed to fix the vertical tubular stanchion (3) to the bearer tube (11) and the number thereof will be variable as a function of the height of the vertical tubular stanchion (3) or as a function of the number of horizontal protective elements (4) to be installed in the provisional railing (1), configuring in this way more or less closed railings.
  • the anchoring system of the positioning and fastening elements (14) can be suppressed, which in this case would consist of a single stepped fishplate (27) in which the horizontal protection elements are introduced, said fishplate being joined to the tube (15) welded to the vertical tubular stanchion (3) or joined directly to said stanchion in the event that it is not necessary to incorporate the tube (15) through considering that the horizontal protection elements (4) are sufficiently near to the actual staircase.
  • a baseboard accessory (29) is introduced by the lower end of the vertical tubular stanchions (3), before the latter are mounted in the supports (2), which baseboard accessory (29) is fixed to the stanchion by tightening a crank (13) as is appreciated in figure 2.
  • a horizontal protection (4) which is adapted by means of an anchoring system (12) similar to that which each of the positioning elements (14) has.
