Definitions

  • the invention relates to a roller shutter-like cover for repair and assembly pits, according to the preamble of claim 1.
  • a roller shutter-like cover of the type described above can be found, for example, in EP-A-0 115 087. Furthermore, reference is made to the roller shutter-like cover according to GB-A-2 060 754.
  • the two previously known constructions have the disadvantage that they consist of many individual parts in place, ie within a prepared floor recess, must be installed and fixed. The work involved in locksmithing and masonry work at the installation site is disproportionately high, although reworking of the floor recess is very often necessary in order to obtain precise beam guidance and to ensure it in the long term. Above all, a precise assignment of the supporting beam guides and the supporting beam drive must be carried out on the spot, which is only possible with experienced and trained personnel. Local construction workers are therefore usually unusable or, if appropriate, too expensive.
  • the present invention has for its object to provide a cover of the types mentioned that can be assembled and adjusted on site with little effort.
  • the roller shutter-like cover is provided by the manufacturer as a closed structural unit, which then only has to be inserted and fixed on site in the base recess provided.
  • a ready-to-install pit is built, which is transported as a whole or as a unit to the place of use.
  • the structural unit preferably also includes all drive elements, so that only a fine adjustment of the components assigned to one another is required at the point of use. It is no longer a problem if the longitudinal side walls of the base recess do not run exactly parallel to one another.
  • the only decisive factor for the function of the cover according to the invention is the self-contained structural unit, which only has to be fixed within the base recess.
  • Boundary walls of the bottom recess insert spacer elements of different lengths, which are preferably penetrated by fastening anchors of different lengths.
  • the structural unit of the construction according to the invention is completed by the measures according to claim 6. Accordingly, it includes its own water drainage system, so that corresponding precautions no longer have to be taken in the floor recess, as was previously the case.
  • the longitudinal side wall construction according to claim 7 is particularly material-saving and light.
  • roller shutter-like cover according to claims 8 and / or 9 is characterized by the sliding principle known per se (see, among other things, public tender of the Building 5 / IV department of the Office of the Upper Austrian Provincial Government for the construction of the new building of the Autobahnmeisterei in Wels, Austria, from 26 February 1981), the special feature being the support of the supporting beams according to the invention on the running rails, which is ensured by the supporting beams assigned to the supporting beams, the axes of which are preferably designed as an extension of the articulated axes of the chain links. In this way you get a particularly simple and reliable Support beam support, which also has the advantage that the cover can be lifted at its free end by a person accidentally trapped in the installation pit.
  • the accidentally trapped person can free himself from his predicament.
  • This is in the prior art, such as. B. is also embodied by DE-A-33 45 018 or EP-A-115 087, not possible due to the U-shaped guide rails provided there, which are arranged above the actual running rails for the supporting beams and projecting on the end faces of the supporting beams Leadership roles are assigned separately.
  • the U-shaped guide rails are intended to prevent the supporting beams from being lifted upwards; accordingly, the self-liberation described above of a person accidentally trapped in the assembly pit is not possible.
  • the assembly pit 10 shown in FIGS. 1 and 2, partly in side view and partly in section, is provided with a roller shutter-like cover 11 (see FIG. 2) with a plurality of parallel support beams 12, the ends of which are supported on rails 13 arranged on the edge of the pit and are connected on the underside by means of parallel chains 14 running at right angles to the supporting beams.
  • the chains 14 are intended for engagement in chain wheels driven by a drive (geared motor 15 in FIG. 2), which are indicated in FIGS. 1 and 2 with the reference number 16.
  • each support beam 12 forms a link in a chain 14, the joints 17 of which are assigned to the gaps between the support beams 12, arranged in the closed position of the cover 11 at the lower end of the gap and for engaging in circumferential recesses of the chain wheels 16 which slide the supporting beams into the covering position of the covering.
  • a detailed description and representation of this construction is unnecessary.
  • FIGS. 1 and 2 and FIG. 3 show that no measures have been taken to prevent lifting of the supporting beams 12 or rollers 18 from the rails 13 upwards. This is wanted for the reasons described at the beginning.
  • such precautions as z. B. by DE-U-83 00 368 or EP-A-115 087 are mandatory, are not necessary, especially if it is assembly pits of shorter length, z. B. Car assembly pits.
  • rollers 18 are each arranged at a distance from the associated support beam 12 within their frontal boundary, as can be seen in both Fig. 3 and Fig. 4.
  • the rollers 18 are not laterally over the support beam 12. In this way, an overall compact construction can be achieved, in which the running rails and rollers are properly protected from dirt or the like by the supporting beams 12.
  • the vertical support beam guide and the guide of the support beams in the upper and lower deflection area are each formed by laterally arranged, mutually facing U-profile-like guide rails 22 and 23, 24.
  • the running rails 13 including the return rails 21 and the vertical supporting beam guide elements 22, 23, 24 assigned to them are an integral part of a cassette 25 which can be inserted into a floor recess and which is laterally separated by two spaced apart bases and / or on the front side interconnected longitudinal side walls 26, 27 is limited, in the upper region of which the running rails 13 are arranged or formed on the inside for the support of the diametrical ends of the support beams 12.
  • connection of the two longitudinal side walls from one another is carried out by means of connecting crossbeams arranged at the bottom, which are designed to be telescopic, so that the distance between the two longitudinal side walls 26, 27 can be adapted to the width of the bottom recess, not shown, into which the cassette 25 is to be inserted.
  • the telescoping ability of the connection or cross members 28 arranged on the bottom is indicated in FIG. 2 by the double arrow 29.
  • the connecting cross members 28 are known fixing elements, for. B. cross bolts or the like.
  • connecting crossbeams 30 are also provided in the upper region to keep the two longitudinal side walls 26, 27 apart.
  • the connecting crossbeams 30 are designed in accordance with the connecting crossbeams 28.
  • the connecting cross members 28, 30 are each arranged in the corner region of the cassette 24.
  • the connecting cross members 28, 30 are arranged one above the other on the end faces, as can be seen in FIG. 1. However, there is no need for this, provided the space conditions are somewhat different, especially in the area of the upper deflection wheels, namely chain wheels 16.
  • Fig. 2 shows that between the two sprockets 16, a geared motor 15 is arranged, the continuous drive shaft 31 is operatively connected to the two sprockets 16, in Fig. 2, the operative connection between the geared motor 15 and the right sprocket 16 via a connecting tube 32nd takes place, which is telescopically attachable to the drive shaft 31. Accordingly, the construction allows a change in the distance between the two longitudinal side walls 26, 27 also in the drive area.
  • the stub shaft 16 assigned to the right sprocket 16 in FIG. 2, over which the connecting tube 32 is also slid, is identified by the reference number 33.
  • the left sprocket 16 in FIG. 2 is directly operatively connected to the drive shaft 31.
  • the geared motor 15 is mounted on an end support structure 34, as indicated in FIG. 1.
  • a tread 35 is formed on the bottom inside the cassette 25, which is formed either by a tread of a conventional type or - as here - in the form of butt-fitted plates 36 with a corrugated or the like structured surface .
  • the longitudinal side wall 26 (see FIG. 2) of the cassette 25, which has a water collecting and drainage channel 38 which is inclined slightly downwards and extends into a channel parallel to the longitudinal side wall 26 at this arranged below the tread 35 water guide channel 39 opens.
  • the water channel 39 is also slightly inclined in the longitudinal direction of the cassette 25 in one direction and opens into a water catchment basin or a water drain, possibly with an oil and petrol separator.
  • the transverse drainage in the water channel 38 is marked with the arrow 40. Accordingly, the cassette described represents a self-draining unit that is self-contained.
  • the water channels 38 serving as transverse drains are each formed by upwardly open U-profiles into which the base plates 36 are hooked. For this purpose, corresponding hooking elements 41 are arranged on the underside of the base plates 38.
  • the longitudinal side walls 26, 27 of the cassette 25 are formed by vertical struts 42, each of which the upper running rail 13 or a U-profile carrier 43 carrying this with the lower return rail 21st or as here with a U-profile arranged above the same, which also serves as a water channel 39, to form a rigid side wall construction.
  • vertical struts 42 each of which the upper running rail 13 or a U-profile carrier 43 carrying this with the lower return rail 21st or as here with a U-profile arranged above the same, which also serves as a water channel 39, to form a rigid side wall construction.
  • diagonal salon and / or horizontal struts can be provided.
  • the side wall construction described is particularly light and material-saving.
  • the vertical connecting struts 42 are also formed in the present case as U-profiles, i. H. in itself kink and warp resistant.
  • the already mentioned U-profile supports 43 also serve as a running rail for a pit jack, which can be moved back and forth in the longitudinal direction of the cassette 25 or assembly pit.
  • the legs of the U-profile beams each protrude inwards in such a way that the respective lower legs serve as a raceway for the pit jack, while the respective upper legs support the running rails 13 for the supporting beams 12.
  • Fig. 2 an alternative for the chain drive is shown schematically.
  • the corner transmission 44 comprises a first transmission shaft 47, which is guided through the one longitudinal side wall 27 to the outside and is operatively connected (shaft 46) to the chain wheels 16 or their axes of rotation, and a second transmission shaft which is operatively connected to it and continues upwards to the level of the cover 11 Transmission shaft 48, wherein the operative connection between the transmission shafts 46, 47 on the one hand and 47, 48 on the other hand takes place via angular gears 49 and 50, respectively.
  • the transmission shafts 46, 47, 48 together with the associated gear 49, 50 are arranged in the front region of the cassette, so that they do not hinder the movement space within the cassette or assembly pit.
  • an end wall cover in the form of a swing door 51 or the like is provided on the drive side, which enables access to the drive of the cover 11 for assembly and repair.
