Description

  The present invention relates to a support structure installed in a passenger boarding / alighting apron for supporting a rotander of a boarding bridge, and a boarding bridge including the support structure.

  In general, this type of boarding bridge includes a rotander provided at one end to be connected to an entrance of a terminal building, a cab provided at the other end to be attached to and detached from an entrance of an aircraft, and the cab and the rotander. And a telescopic tunnel part to be connected. The rotander is supported by a support structure installed in an apron on the terminal side. The support structure is constructed as follows, for example (see Patent Document 1).

First, an apron is excavated for several meters so as to meet the specifications of each airport, and then the foundation formed in the shape of a reverse T is fixed to the excavation surface on the terminal side with an anchor. Further, a substrate made of an iron plate is fixed on the foundation with anchor bolts, and a cylindrical column is erected on the substrate. Thereafter, the excavation surface is filled with concrete, and a series of construction work of the support structure is completed. The support structure constructed in this way is usually constructed at the construction stage of the airport. For example, even a small boarding bridge used for a so-called small machine with a small number of passengers, its rotunda. In order to support this, a support structure having a similar structure has been adopted.

  However, the conventional support structure has a large problem that the construction cost is increased and the construction period is inevitably prolonged because the series of construction work is extremely complicated. It was.

  Further, the support structure was originally developed for a large or medium boarding bridge, and was too high in terms of strength and performance for a small boarding bridge. That is, since the boarding bridge for a small machine is formed with a small height and the like, its center of gravity is also set low. For this reason, the external force such as wind load acting on the boarding bridge is relatively small. Therefore, the support structure that supports the external load does not require much strength and rigidity.

  In addition, the support structure may need to be constructed afterwards due to, for example, a change in the aircraft parking layout. Also in this case, conventionally, a support structure similar to that described above has been constructed. In addition, in the subsequent construction, since complicated procedures are required to obtain permission and approval, there is also a disadvantage that a construction period is required more than necessary.

  Therefore, the present invention has been made in view of such a point, and an object of the present invention is to provide a support structure having a simple structure that can be easily constructed in a short period of time and a boarding bridge having the structure. .

  The support structure for a boarding bridge according to the present invention is a support structure installed in an apron to support a rotander of the boarding bridge, and is fixed to the installation surface of the apron by its own weight. Here, “fixed by its own weight” means that it is fixed by simply placing it without using a fixing tool such as an anchor bolt.

  According to this, the support structure is installed at a predetermined position on the terminal side of the apron, and the rotander of the boarding bridge is supported. In this way, since the support structure only needs to be arranged at a predetermined place to be installed, the construction period at the site is greatly shortened compared to the conventional installation work in which civil engineering work was performed on the apron. The In particular, the support structure according to the present invention is useful when it is necessary to construct the support structure afterwards. In other words, since civil engineering work for the apron at the airport is not performed at all, complicated procedures related to prior approval and approval, etc., are unnecessary, and early construction can be started, resulting in shortening the construction period. Can do. Therefore, it will not interfere with the operation of the airport. Further, since the weight of the support structure is sufficiently secured, the support structure is securely and firmly fixed to the installation surface by its own weight. Thereby, the rotunda is favorably supported.

  The support structure may include a base that is fixed to the apron installation surface by its own weight, and a support that is provided on the base and supports the rotander.

  According to this, the support structure is installed at a predetermined position on the apron terminal side, and the rotander of the boarding bridge is supported by the support column. In this case, since the weight of the base of the support structure is sufficiently secured, it is securely and firmly fixed to the installation surface by its own weight. Thereby, the rotunda is favorably supported.

  Furthermore, you may comprise the said base with a steel frame structure. According to this, it is possible to sufficiently secure the weight by appropriately combining the steel frame members to form the base. In addition, since the structure of the steel frame structure can be easily changed by increasing or decreasing the number of steel members, it has flexibility to cope with various rotanders having different shapes and weights. Furthermore, the cost of the support structure can be reduced.

  The steel frame structure can be covered with a filler. According to this, the strength and weight of the support structure as a structure increase, and the appearance appearance becomes very good.

  Furthermore, the base may be formed in a cylindrical shape. According to this, it becomes possible to reliably support the rotander under substantially the same conditions, regardless of where the boarding bridge is arranged with respect to the support structure. In other words, it is not necessary to arrange the support structure on the installation surface in consideration of the placement position of the boarding bridge. For example, compared to the case where the base is formed in a rectangular shape, the construction work on site is simplified. It will be planned.

  The base may be configured to include a boarding bridge rotander in plan view. According to this, the boarding bridge does not inadvertently roll over due to wind load or the like, and the rotander can be supported in a stable state.

  Furthermore, the boarding bridge according to the present invention includes the support structure for the boarding bridge and is configured such that the rotander is connected to the first floor of the terminal building.

  According to this, since the center of gravity of the boarding bridge itself is set low, the acting wind load and the like are reduced. As a result, the boarding bridge has good stability and its rotander is supported by the support structure.

  Furthermore, the support structure for a boarding bridge according to the present invention has a practical advantage in that its overall configuration is very simple, and therefore it can be manufactured easily and inexpensively.

  As described above, the support structure according to the present invention is significantly different from the conventional structure in which the apron is subjected to civil engineering work and the support structure is integrally constructed in the apron, and the apron is not subjected to any civil engineering work. This was developed under a completely new idea of fixing the support structure to the apron installation surface by utilizing the weight of the support structure.

  As described above, according to the present invention, it is possible to obtain a support structure that has a very simple structure and can be easily constructed in a short period of time and can firmly support the rotander of the boarding bridge.

  Hereinafter, an embodiment of a support structure according to the present invention will be described with reference to the drawings. As shown in FIG. 1, a support structure 1 according to the present embodiment is provided with a base 2 having a predetermined thickness and formed in a substantially square plane, and a central portion of the upper surface of the base 2. The support 3 is provided.

  The base 2 is composed of a frame 4 formed by a plurality of H-sections as shown by broken lines in FIG. 2 and a plurality of mounting plates 5 and 6 installed on predetermined H-sections of the frame 4. The steel frame structure 7 and a filler 8 such as concrete filled around and inside the steel frame structure 7 so as to cover it. Each mounting plate 5, 6 is formed with a pair of screw holes 9. An anchor bolt 10 made of a screw rod is screwed into the screw hole 9, and a nut 11 is fastened to the anchor bolt 10 so that the upper end of the anchor bolt 10 protrudes to the outside. It is fixed. However, the specific configuration such as the shape and material of the base 2 is not limited to this.

  The support column 3 includes a flat rectangular fixing plate 12 provided at the lower end portion to be fixed to the mounting plates 5 and 6 of the base 2, a substantially cylindrical support body 13 provided at a substantially central portion thereof, And a disk-shaped connecting plate 14 provided at the top. The anchor bolts 10 are inserted into a plurality of circular holes (not shown) formed in the fixing plate 12, and the support 3 is fixed on the base 2 by fastening a double nut 15 thereto. Yes. In addition, a plurality of ribs 16 are provided on the outer peripheral surface of the column main body 13 so as to protrude laterally in order to ensure strength. However, the structure of each part of the support | pillar 3 is not restricted to this.

  When installing the support structure 1 having such a configuration in the apron E of the airport, as shown in FIG. 1, the support structure 1 may be arranged so that the base 2 of the support structure 1 is located at the place to be installed. Thus, the installation of the support structure 1 can be easily completed by such work. Therefore, the construction period at the site can be greatly shortened as compared with the conventional installation work in which civil engineering work has been performed on the apron E. In particular, the support structure 1 according to the present embodiment is useful when the support structure 1 needs to be constructed afterwards. In other words, since civil engineering work for the apron E at the airport is not performed at all, complicated procedures related to permission and approval before construction are unnecessary, and early construction can be started, thereby shortening the construction period. be able to. Therefore, it will not interfere with the operation of the airport.

  In addition, since the base 2 has a sufficient weight, the base 2 is firmly fixed to the apron E by its own weight, and does not move carelessly from the installation location.

  The support structure 1 can be constructed by an apron E at the airport or the like, but may be produced in advance in a factory, for example. According to this, since it is only necessary to carry in and install the support structure 1 at the airport, the construction period can be further shortened.

  Next, the case where the support structure 1 is used to support the rotander 31 of the boarding bridge 30 as shown in FIG. 3 will be described.

  As shown in the figure, the boarding bridge 30 connects a rotander 31 connected to an entrance / exit of an airport terminal building, a cab 32 attached to and detached from an entrance / exit of an aircraft, and the cab 32 and the rotander 31. And a tunnel portion 33. Further, the boarding bridge 30 is configured to incline downward toward the rotander 31 side. Thereby, the rotunda 31 can be connected to the entrance on the lower side such as the first floor or the second floor of the terminal building. Further, since the center of gravity of the boarding bridge 30 itself is set low, the acting wind load and the like are reduced. As a result, the boarding bridge 30 has good stability as will be described later, and the rotander 31 is supported by the support structure 1.

  The tunnel portion 33 includes a first tunnel 33a on the rotander 31 side, a second tunnel 33b that is connected to the first tunnel 33a in a telescopic manner, and a connection tunnel 33c that is connected between the second tunnel 33b and the cab 32. It is made up of. A wheel unit 35 having a pair of traveling wheels 34 is attached to the lower part of the connection tunnel 33c. The rotander 31 is configured to be rotatable about a vertical axis.

  When the rotander 31 of the boarding bridge 30 having such a configuration is supported by the support structure 1, the rotander 31 may be installed on the support column 3 of the support structure 1 using, for example, a crane. In a state where the rotander 31 is connected to the entrance / exit of the terminal building, the lower surface portion of the rotander 31 is fixed to the connecting plate 14 of the support column 3 with a bolt or the like (not shown).

  The rotander 31 of the boarding bridge 30 is configured to be included in the base 2 in a plan view as shown in FIG. As a result, the boarding bridge 30 does not inadvertently roll over due to wind load or the like, and the rotander 31 is supported in a stable state.

  In addition, since the support structure 1 according to the present embodiment has an extremely simple configuration including the base 2 and the support column 3, it can be manufactured easily and inexpensively, while the wind load acting on the support structure 1 can be reduced. It has the necessary and sufficient strength to support a relatively small and small boarding bridge 30.

  Furthermore, the steel frame structure 7 that constitutes the base 2 can be easily manufactured to a base 2 having a desired weight by appropriately changing and adjusting the type and number of H-shaped steels to be used. It is. Accordingly, it is possible to flexibly cope with a change in the specifications of the boarding bridge 30 and the like.

  In addition, although the base 2 in the said embodiment is comprised by filling the steel frame structure 7 with the filler 8, the filler 8 should just be filled as needed. If no particular appearance is required, it may be omitted.

  Further, the base 2 is not necessarily required to have the steel frame structure 7. In short, the base 2 may be configured to be fixable to the apron installation surface by its own weight.

  Furthermore, the shape of the base 2 itself of the support structure 1 is not limited to that of the above embodiment, and may be formed in a cylindrical shape. According to this, regardless of the position of the boarding bridge 30 with respect to the support structure 1 due to the relationship with the entrance / exit on the terminal side, the rotander 31 can be reliably supported under substantially the same conditions. It becomes. That is, it is not necessary to arrange the support structure 1 on the installation surface in consideration of the position where the boarding bridge 30 is disposed. For example, compared with the case where the base 2 is formed in a rectangular shape, the construction work at the site is not necessary. Simplification can be achieved.

  In the above embodiment, the rotander 31 of the boarding bridge 30 is configured to be included in the base 2 in plan view. However, this configuration is not necessarily required.

  In addition, the structure of the support 3 such as the shape of the support column 3 can be arbitrarily changed within the range intended by the present invention.

  Note that the support structure 1 according to the present invention does not need to be configured by the base 2 and the column 3 as in the above embodiment. In short, the support structure 1 may be configured to be able to support the rotander 31 of the boarding bridge 30 and be fixed to the installation surface of the apron E by its own weight.

  Further, the boarding bridge 30 to which the support structure 1 according to the present invention can be applied is not limited to the one shown in the above embodiment, and can be widely applied to other boarding bridges 30. is there.

  As described above, the present invention is particularly useful for a support structure for a boarding bridge used for a small machine.

It is a front view which shows the state which supported the rotander with the support structure which concerns on one Embodiment of this invention. It is a top view which shows the base of the same support structure. It is a top view which shows the use condition.
