Description

[0001] Hangar overhead door frame

[0002] Description

[0003] The utility model relates to metal structures and discloses the design of a hangar gate frame, implying the possibility of placing the gate outside the hangar.

[0004] A MOVABLE FRAME IN A SUSPENSION is known from the prior art [JPH02221581A, published 04.09.1990]. The hangar provides in its opening part one or two laid guides 3, when closing the opening part all doors 2 can be located transversely on the guide 3. Then the opening part opens into its end part in accordance with the number of door panels 2, the main block 10 of the shutter box, installed with the possibility of reciprocating movement in the direction orthogonal to the rail 3, along the guide laid in the direction of the surface of the outer door 2 on the floor. When the opening part is opened and in the closed state, in each sheet of door 2, when moving outward, the main block 10 of the gate frame moves in one direction by the amount of the thickness of each sheet of door 2, and all doors 2 are sequentially supplied on the guide 3 or stored in the main block of the frame 10.

[0005] The disadvantage of the analogue is the insufficient rigidity of the structure of the power frame of the overhead gate.

[0006] Also known is a hangar door and a hangar equipped with such a door [EP1059412A1, published 13.12.2000]. The hangar door comprises at least one door panel (21, 22) provided with a door cover intended for movable inclusion in the wall of the hangar (1). The door panel (21, 22) comprises at least one segment (30) of the door panel, in which at least a part of the cover is mounted movably and can assume an open state. Thus, in the open state of the door, it is possible to release an opening in the door panel, thereby actively controlling the influence of the door on the air flows around the door. The hangar (1) equipped with such a door comprises generally a linear guide (11, 14), in which the door panel (21, 22) is mounted with the possibility of linear movement.

[0007] The disadvantage of the analogue is the insufficient rigidity of the design of the load-bearing frame of the overhead gate. A LARGE DOOR DEVICE is also known [JP2003172073 A, published 20.06.2003]. The large door device is made of a lower guide 12, an upper guide groove 13, etc., which arcuately connect the façade of a large building 1 with the outer part of the building 1, and arcuate large doors I la, 11b, which close the façade of the building with the possibility of opening 1, moving along the lower guide 12 and the upper guide groove 13. In accordance with the design of the large door, the large door 11a moves in the directions indicated by arrow A, whereby it arcuately moves between the façade of the building 1 and its right outer part in order to open / close the façade. Next, the large door 11b moves in the directions indicated by arrow A, as a result of which it moves in an arc between the facade of building 1 and its left outer part, opening / closing the facade.

[0008] The disadvantage of the analogue is the insufficient rigidity of the structure of the power frame of the overhead gate.

[0009] The purpose of the utility model is to place the gate outside the hangar.

[0010] The technical result achieved in the utility model is an increase in the rigidity of the power frame of the overhead hangar gates.

[0011] This technical result is achieved due to the fact that the frame of the overhead gates of the hangar contains a load-bearing frame 4, guides 11 for the gate leaves 6, made on the load-bearing frame 4 and the gate leaves 6, located in these guides 11, is characterized in that the load-bearing frame 4 is made of a vertical 1 and horizontal 2 base, wherein the vertical base 1 is fixed to the spans 5 of the hangar, the horizontal base 2 is fixed perpendicular to the vertical base 1 of the hangar, with one side located inside the hangar, and the other ends with a metal truss 3, made outside the hangar parallel to its gate opening 12, wherein the metal truss 3 is made wider than the span 5 of the hangar by the width of the gate 6, and is equipped with guides 11 in its lower part, and the parts of the metal truss 3 protruding beyond the span 5 of the hangar are mounted on support posts 8 with the formation of a box 10 for gate 6,which are located between the support posts 8 and the metal truss 3 of the hangar, wherein the horizontal 2 and vertical 1 bases are secured with stiffening ribs 7, and the stiffening ribs 7 are fastened together by longitudinal beams 9. In particular, guides 17 are secured between the support posts 8, in the center of which a free space 18 is made, made with a length not less than the maximum width of the chassis of the equipment placed inside the hangar.

[0012] The essence of the utility model is explained by drawings.

[0013] Brief description of the drawings.

[0014] Fig. 1 shows a side view of the device.

[0015] Fig. 2 shows the general view.

[0016] Fig. 3 shows a metal truss.

[0017] The following are indicated on the figures: 1 - vertical base, 2 - horizontal base, 3 - metal truss, 4 - power frame, 5 - hangar span, 6 - gate leaves, 7 - stiffeners, 8 - support posts, 9 - longitudinal beams, 10 - box, 11 - guides, 12 - gate opening, 13 - belt, 14 - post, 15 - diagonal, 16 - node, 17 - guides, 18 - free space.

[0018] A hangar is a frame structure, complex building and structure for industrial, warehouse, agricultural, general military, and aviation purposes.

[0019] A truss is a metal structure made of rods connected to each other at nodes and forming a geometric system.

[0020] The frame of the overhead hangar gate (Fig. 1) consists of a vertical base 1, a horizontal base 2, and a metal truss 3. A load-bearing frame 4, consisting of a vertical base 1 and a horizontal base 2, is used to secure the overhead gate. Vertical base 1 is rigidly fixed, for example, by a bolted connection, at the top of the first hangar span 5, above the gate opening 12, which must be closed by the gate. When the vertical bases are mounted on the U-shaped hangar span 5, their unfastened ends form a flat horizontal plane parallel to the floor and located at a height exceeding the height of the equipment stored in the hangar. Horizontal base 2 is mounted perpendicular to it using a bolted connection, serving to accommodate and secure metal truss 3.The metal truss 3 is a spatial horizontal truss structure, realized by means of rigid fastening of trusses with parallel belts to each other with the formation of a rectangular spatial truss structure, for example, by a bolted connection, and is a power element serving to accommodate the gate leaves 6 on itself with the possibility of movement with the help of guides 11.

[0021] To ensure the rigidity of the structure (Fig. 2), the load-bearing frame 4 is equipped with stiffening ribs 7, connecting the vertical 1 and horizontal 2 bases diagonally. To ensure additional rigidity of the structure during the installation of the suspended gate group in the hangar, the following spans 5 are additionally reinforced after the one to which the load-bearing structure 4 is installed, connecting at least the first two spans 5 with stiffening ribs 7. The stiffening ribs 7, located above the horizontal spatial truss structure 3, are additionally connected to each other by longitudinal beams 9, which provides both additional reinforcement of the structure and the possibility of placing and fastening sheet material on them for protective functions. Outside the hangar, on the sides of the suspended gate group, the load-bearing structure 4 is additionally reinforced with support posts 8, forming a box 10, intended for placing gate leaves 6 for protective functions inside it.Between the support posts 8, guides 17 are made at the bottom, providing additional support for the gate leaves 6, while between these guides 17, a free space 18 is made, made in length not less than the maximum width of the chassis of the equipment placed inside the hangar.

[0022] The use of a suspended gate system allows for the saving of useful space within the hangar, as the gates are moved outside the hangar and do not take up space within. This reduces the height of the hangar supports, which reduces the overall metal consumption of the hangar and allows the installation of the gate system in both new and reconstructed hangars.

[0023] The technical result claimed in the utility model is achieved by implementing the load-bearing frame 4 from a vertical 1 and horizontal 2 base, since by implementing the design of the load-bearing frame 4 in this way, it is possible to select the height of the gate opening 12 for various equipment due to the vertical base 1, which is attached to the spans 5 of the hangar, and the perpendicularly located horizontal base 2 allows for the placement of a metal truss 3 with guides 11 for the gate 6 parallel to the gate opening 12, thereby achieving the necessary rigidity of the load-bearing frame, allowing for the placement of the gate 6 outside the hangar, affecting the technical result. Implementing guides 11 for the gate 6 on the metal truss 3 will ensure the rigidity of the structure due to the high bending strength of the metal truss, thereby avoiding the jamming of the gate leaves 6 in these guides 11, thereby affecting the technical result.

[0024] The implementation of a suspended metal truss 3 outside the span 5 ensures a reduction in the required height of the hangar span 5 supports for the passage of equipment inside it, thereby reducing the height of the hangar required for equipment, and accordingly reducing its windage and increasing its rigidity

[0025] The execution of the metal truss 3 wider than the span 5 of the hangar provides the necessary space for the execution of the guides 11, allowing the gate to be moved beyond the gate opening 12, thereby allowing the horizontal movement of the gate in both directions relative to the opening 5 of the hangar and increasing the gate opening 12, thereby freeing up space inside the hangar, allowing the arrangement of the gate leaves 6 outside the hangar and indirectly influencing the technical result.

[0026] The implementation of the metal truss 3 on the support posts 8 in places protruding beyond the span 5 of the hangar will provide additional rigidity to the structure and will allow the formation of a box 10 between the metal truss 3 and the support posts 8 for the gate leaves 6 for the placement, storage and protection of the gate leaves 6 from various types of external influences, and in essence identical to the storage of the shifted gate leaves 6 inside the hangar, thereby affecting the technical result.

[0027] Strengthening the horizontal base 2 and vertical base 1 with stiffeners 7 and fastening them together with longitudinal beams 9 will further strengthen the load-bearing frame 4 of the gate leaves 6, allowing the metal truss 3 to extend beyond the hangar span 5, thereby improving the technical result. A canopy is also formed between the stiffeners 7 and the longitudinal beams 9. Placing protective material on this canopy will provide additional protection for the gate leaves 6 and guides 11 from various external influences.

[0028] Implementing the gate load-bearing frame as described above allows for a 24% increase in the rigidity of the hangar's overhead gate load-bearing frame. This data was obtained during hangar construction in accordance with the text of this utility model. During the construction of the load-bearing frame with supports as described in this utility model, three spatial truss structures were used to construct the metal truss. These structures consist of a metal structure composed of rods connected at 16 joints, forming a geometric system. A flat truss with parallel chords 13 was used to implement the spatial truss structure. The chords 13 are structurally composed of two parallel longitudinal beams with 16 fastening joints located at equal distances from each other on these beams.These 16 fastening nodes are transversely mounted with struts 14 supporting the compressive load, and between two adjacent 16 fastening nodes, diagonal braces 15 supporting both the compressive and tensile loads are installed. Four flat trusses were then rigidly secured to each other by chords to form a rectangle. This example is just one of the options used; other types of truss structures not described here can also be used.

[0029] The method for attaching the door group to the hangar begins with determining the height at which the door group will be mounted. This height is determined by the height of the equipment planned to be stored in the hangar. Next, a vertical base is installed on the first, and if necessary, the second or third, bay of the hangar, to which the load-bearing frame with a horizontal base will be attached. Next, a horizontal spatial truss structure is placed on the horizontal base of the load-bearing frame of the door group and secured to this base. Next, stiffening ribs are attached diagonally between the vertical and horizontal bases of the load-bearing frame of the door group, and connected with longitudinal beams.

[0030] If necessary, to ensure increased rigidity of the structure, the vertical base of the hangar span is connected with stiffening ribs to the next hangar span by an extended horizontal base and connected with stiffening ribs to the hangar spans and the vertical base.

[0031] Constructing a hangar overhead door frame in accordance with this utility model increases the rigidity of the frame structure, allowing the door assembly to be suspended outside the hangar. This allows for the power units and door guides to be mounted on the supporting truss, allowing for a door opening without curbs or additional entry devices. Furthermore, implementing an overhead door frame located outside the hangar reduces the overall hangar volume by reducing the span supports, thereby reducing the hangar's metal consumption and operating costs, as well as the heating and ventilation system.
