Definitions

  • the present invention relates to an operator access door for underground buildings which can be used for telephony applications, as handling and/or electric transformation centers, for water pumping facilities, gas distribution facilities and other uses.
  • the object of the invention consists of an access door allowing the operators to easily access the inside of the building in order to perform the typical maintenance and operation tasks of the installed equipment, designed such that it is resistant to mechanical stress, such as the passage of pedestrians or the passage of vehicles over such building for example, having reduced weight and allowing the incorporation of different closures.
  • the underground buildings used for industrial purposes are generally formed by a body or casing and a cover forming the floor or surface which can traveled over, said cover being able to be covered with any type of covering, such as paving blocks, tiles, etc.
  • the assembly formed by the cover-casing can be of a prefabricated or a civil construction nature, made both of concrete and of other materials, inside which different industrial equipment is housed, such as for electric distribution, telephony, gas or water for example.
  • the indoor operation constructions have the advantage of providing the operators with greater protection against atmospheric agents, and above all making it difficult for passers-by to access the equipment installed therein during the operation.
  • said buildings In order to perform operation and maintenance work, said buildings usually have an opening in their cover which is closed by means of a door.
  • These doors for operation access inside the building can be formed from one single lid or from several lids or semi-trapdoors.
  • some examples of patents and utility models can be mentioned, such as ES2181581 , ES2157770 , ES1055376 and ES1049753 for example, in which these types of doors for operator access are defined.
  • Patent ES2157770 describes a solution in which the access door is formed by two semi-trapdoors, whereas in the rest of the examples the access door is formed by a single lid.
  • the lids of the access doors are formed by several parts, including a preferably bellmouthed and stepped stainless steel perimetric frame, and incorporating therein a concrete plate with a steel framework, sufficiently robust to withstand the stress both due to the passage of pedestrians and due to the passage of vehicles over the door.
  • the lids of the access door are usually aided by an automatic opening and closing system, for example based on pneumatic or hydraulic cylinders compensating for the weight of the door, so that these doors can be easily handled by the operators.
  • lids forming the access door are complemented with protection handrails, which can be folded in the closing, remaining concealed inside the building, whereas in the open position they can be unfolded, such that together with the lids of the door they define a protection surround around the access opening for the purpose of preventing the risk of the passers-by falling inside.
  • the access doors for operators comprise a closure preventing the opening of said door when the industrial equipment which the building contains is in operation.
  • the access doors are normally closed by means of fixing screws which can only be removed through a special key provided by the manufacturer. These fixing screws can be accessed from outside the building, whereby they are exposed to external damage, such as acts of vandalism or atmospheric agents, the latter being able to cause the deterioration of said screws over time, due to rusting for example, and consequently making their removal impossible at the time of performing operation or maintenance work.
  • the access door pivots through a hinged shaft when it is subjected to opening and closing operations.
  • the hinges joining the lid with the frame of the opening of the cover are normally outer hinges, therefore, as occurs with the closure, said hinges are exposed to external damages, problems being able to arise in the opening and in the closing of the lid in operation or maintenance work.
  • the present invention relates to an operator access door for underground buildings, which can be used for telephony applications, as handling and/or electric transformation centers, for water pumping facilities, for gas distribution facilities, etc. and which are structured from a body having a cover at its upper part, these buildings being able to be civil construction buildings or buildings of a prefabricated nature, made both of concrete and of other materials.
  • the operator access door comprising a main lid collapsible with respect to a frame is arranged on the mentioned cover, which lid is formed as a single part, made of a material with reduced weight and with a non-slippery surface, for example a metal material such as cast aluminum, which, as a result of the reinforcement means comprised by said lid, such as transverse and/or longitudinal reinforcement ribs, in turn has sufficient robustness to withstand the stress caused by the passage of pedestrians or even by the passage of vehicles on the lid itself.
  • This lid also allows the easy access of the operators easily and working inside the building in maintenance and operation tasks.
  • an automatic opening and closing system which for example can consist of hydraulic or pneumatic struts which are simpler and have a lesser load than those necessary to open a heavier lid than those known up until now. These struts with a lesser load are in turn able to maintain the lid in its open position, ensuring the locking in this position, preventing any gust of wind or the fall of an object from accidentally closing said lid.
  • the stress which the operator must carry out in order to open and close the lid is the minimal.
  • This lid or main lid incorporates a second auxiliary lid integrated therein, which auxiliary lid conceals and protects at least one closure of the main lid, such as a padlock, a lock, etc., such that said closure cannot be to the object of acts of vandalism nor subjected to atmospheric agents which can deteriorate it.
  • the auxiliary lid is thus provided with at least one closing element in order to prevent accessing the closure of the main lid, this closing element being able to consist of a fixing screw, for example an Allen screw.
  • auxiliary lid when opening the auxiliary lid, it can be completely separated from the main lid or can be joined to the main lid through the mentioned closing element, such that with the loosening of said closing element, this auxiliary lid can be lifted and turned, leaving the access to the closure of the main lid free and preventing the possibility of said auxiliary lid being lost.
  • Another particularity of the operator access door according to this invention relates to the hinging elements which allow pivoting the main lid, which can consist of hinges which are installed at the inner part of the main lid, such that they are protected from external damage.
  • Both the space comprised between the frame and the main lid and the space between the main lid and the auxiliary lid, are duly sealed by means of sealing gaskets, for example rubber gaskets, such that the introduction of water, humidity etc. which can damage the equipment inside the building as well as the closure of the main lid, is prevented.
  • sealing gaskets for example rubber gaskets
  • the access door for underground buildings is complemented with a protection means, such as a fence that is foldable and unfoldable on the frame of the access door for example, such that in the open position of the lid there is defined a protection surround preventing passers-by from accidentally falling inside the building.
  • a protection means such as a fence that is foldable and unfoldable on the frame of the access door for example, such that in the open position of the lid there is defined a protection surround preventing passers-by from accidentally falling inside the building.
  • Figure 1 shows an underground building (12) intended to be used as a handling and/or electric transformation center comprising therein electronic and electrical equipment, formed by a body (2) and an upper cover (1), this building (12) being able to be a civil construction building or a building of a prefabricated nature, made both of concrete and of other materials.
  • the cover (1) of the underground building (12) comprises an access door according to the invention, which is formed by a main lid (4) collapsible toward the outside with respect to a frame (3) integrated in the upper cover (1), which cover has a non-slippery surface, it is configured in a single part and is made of a material with reduced weight, such as a metal material such as cast aluminum.
  • This main lid (4) is also able to resist mechanical stress such as for example those caused by the passage of pedestrians or even by the passage of vehicles over such lid, said lid (4) comprising to that end transverse and longitudinal reinforcement ribs (13) providing it with sufficient mechanical strength.
  • the lid (4) incorporates hydraulic or pneumatic struts (11), used for opening/closing the lid (4), with a lesser load than the struts used up until now.
  • the feature of the reduced weight allows handling the door even without struts (11) in the event of gas loss of any of them, the stress which the operator must carry out in this case being minimal.
  • said main lid (4) in turn comprises a second auxiliary lid (5) integrated therein, which auxiliary lid conceals and protects a closure (6) of the main lid (4) from the outside, which according to the electric company to which said building (12) belongs, can consist either of a padlock closure or a lock closure, as shown in Figure 3 .
  • Said auxiliary lid (5) is complemented with a closing element (7) which can be accessed from the outside, which element can consist of a fixing screw, such as an Allen screw for example, such that by means of its loosening it allows lifting and turning said lid (5) without the latter being separated from the main lid (4) and thus accessing the closure (6).
  • the main lid (4) comprises hinges (8), installed at the inner part of the frame (3), such that they are protected from any external damage they may experience.
  • this access door has a fence (10) that is foldable and unfoldable with respect to the frame (3), forming together with the main lid (4) in its open position a protection barrier preventing passers-by from accidentally falling inside the building (12).
