Description

[Technical field]

[0001] The present invention relates to a tube structure with improved performance. [Background technology]

[0002] It is to be apparent that the material discussed in this section is merely provided as background information for the present invention and may not constitute prior art.

[0003] Generally, high-speed train systems must solve two resistance problems depending on the speed: first, aerodynamic running bodies are designed to reduce the exponentially increasing air resistance, and second, magnetic levitation systems are introduced to reduce friction between the running bodies and the tracks.

[0004] The technology introduced for this purpose is the Hyperloop system, which is a system that uses magnetic levitation to transport moving vehicles in a sealed tube at a pressure of approximately 0.001 atmosphere or less.

[0005] While the electromagnetic and mechanical systems of such a hyperloop device are important, it is also crucial to realize a tube structure capable of maintaining a sub-vacuum state of approximately 0.001 atmospheres or less, which accounts for more than 50% of the initial investment cost. Summary of the Invention [Problem to be solved by the invention]

[0006] An aspect of the present invention is to provide a tube structure capable of improving resistance to a collapse load while reducing the thickness of a tube main body. [Means for solving the problem]

[0014] The reinforcing block portion may have a minimum installation height in the height direction within a range of 10 to 20% of the installation width.

[0015] The tube body may further include a fastening portion that is installed to protrude from an outer surface of the tube body and is fastened to the reinforcing block portion while penetrating the reinforcing block portion to connect the tube body and the reinforcing block portion.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0023] Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. However, the embodiments of the present invention can be modified in various different forms, and the scope of the present invention is not limited to the embodiments described below. Furthermore, the embodiments of the present invention are provided to more completely explain the present invention to those having average knowledge in the art. The shapes and sizes of elements in the drawings may be exaggerated for clearer explanation.

[0024] The tube structure 10 according to the present invention is intended to be used as a tube in which a running body moves at a fixed interval from the inner surface and the inside is a vacuum, and such a tube structure 10 must have sufficient resistance to collapse load.

[0025] The tube structure 10 of the present invention is intended to introduce into the sealed tube structure 10 a state of 0.001 atmosphere, which is the stratospheric level at 50 km above the ground, instead of the existing atmospheric pressure (1 atmosphere).

[0026] In such attempts, while systems that electromagnetically and mechanically levitate and propel the system are important, it is also important to realize a tube structure 10 that can maintain a vacuum state equivalent to 0.001 atmospheres or less, or a state equivalent to a vacuum, in the infrastructure, which accounts for more than 50% of the initial investment costs.

[0027] FIG. 1 is a diagram showing the thickness difference between a support tube structure that supports a collapse load and a support tube structure that supports a collapse load and a bending load simultaneously.

[0028] When only the collapse load is considered, as in (a) of Figure 1, the thickness of the support tube structure can be made thin. However, when both the collapse load and bending load are considered at the same time, as in (b) of Figure 1, the thickness of the support tube structure must be made thicker.

[0029] The tube structure 10 of the present invention is intended to stably support collapse loads and bending loads while reducing the thickness of the tube body by providing a reinforcing block portion on the tube body.

[0030] FIG. 2 is a diagram showing a tube structure 1 according to a comparative example to be compared with the tube structure of the present invention.

[0031] 2, the tube structure 1 according to the comparative example of the present invention is different from the tube structure of the present invention in that it does not have a reinforcing block part and is formed by connecting a plurality of unit tubes 1a made of steel in the length direction. At this time, the unit tubes 1a are connected by bolting the flanges 1b.

[0032] In the case of the comparative example, in order to maintain a vacuum while resisting the bending load, it is necessary to fabricate a flange 1b that is very precise and capable of resisting the load, which entails the problem of high cost.

[0033] In the comparative example, when the diameter of the tube structure 1 is increased, the thickness of the tube body made of steel also becomes relatively larger. However, in accordance with the design standard for normal pipelines (DNV OS F101), when the diameter is increased to 4 m, the safe thickness of the unit tube 1 a that ensures resistance performance against the collapse load as well as the safety factor increases to 28.4 mm.

[0034] Of course, if the diameter of the tube structure 1 is greater than 4 m, the thickness of the unit tube 1a will be greater than 28.4 mm.

[0035] In the comparative example, the thickness of the unit tube 1a having a large diameter becomes thicker, and the amount of steel required to manufacture the unit tube 1a increases exponentially, resulting in a rapid increase in initial investment costs.

[0036] In addition, in the comparative example, if the diameter of the tube structure 1 becomes larger than 4 m, the thickness of the steel material for manufacturing the unit tubes 1a becomes larger than 28.4 mm, and if the thickness becomes larger than 25 mm, there is a problem that significant constraints are imposed on the production method of the unit tubes 1a.

[0037] Generally, hot rolled coils are set up to produce thicknesses of 25mm or less, and steel products with thicknesses of 25mm or more that cannot be produced with hot rolled coils must be produced as plates. However, plate products have the problem of much higher production costs because they use manufacturing methods (JCO, UOE, roll bending, etc.) that do not allow continuous processes when producing unit tubes.

[0038] Therefore, in the production of the unit tubes that form the tube structure, a continuous process is possible, and the thickness of the tube can be set to 25 mm or less so that the initial investment cost can be reduced.

[0039] For this reason, the tube structure 10 of the present invention can add a reinforcing block portion 200 to the tube body portion, thereby reducing the thickness of the tube body portion 100 to 25 mm or less.

[0040] Hereinafter, components included in the tube structure 10 according to an embodiment of the present invention will be described in detail with reference to FIGS.

[0041] The tube structure 10 according to one embodiment of the present invention may include a tube body portion 100 and a reinforcing block portion 200 .

[0042] The tube body 100 can form a movement path S along which a traveling body moves inside, and the traveling body can move at a certain interval from the inner surface of the tube body 100.

[0043] As an example, the traveling object may be a train that travels along the travel path S inside the tube main body 100 at a speed of 300 km / h or more.

[0044] The tube body 100 can support a collapse load caused by a pressure difference between atmospheric pressure and an internal pressure of the tube body 100 that is lower than atmospheric pressure.

[0045] The tube body 100 can have a vacuum or vacuum-like internal pressure.

[0046] When the inside of the tube body 100 is in a vacuum state, there is no internal pressure in the tube body 100. When it is in a vacuum-like state, an extremely low internal pressure may exist inside the tube body 100. As an example, the tube body 100 may have an internal pressure of 0.001 atmosphere or less in a vacuum-like state.

[0047] The reinforcing block portion 200 is made of a material different from that of the tube body portion 100, and is joined to the tube body portion 100 along the longitudinal direction D1 to reinforce the tube body portion 100.

[0048] The reinforcing block portion 200 can mainly support bending loads generated by the weight of the tube structure 10 itself and the load of a traveling body.

[0049] The reinforcing block portion 200 has a contact surface 210 that contacts the outer surface of the tube body portion 100 in a surface contact manner, and the contact surface 210 may be formed to extend along a length direction D1 of the reinforcing block portion 200.

[0050] The reinforcing block portion 200 is installed along the longitudinal direction D1 of the tube body portion 100, and the reinforcing block portion 200 and the tube body portion 100 may have lengths corresponding to each other.

[0051] The reinforcing block part 200 has a contact surface 210 formed on a lower side thereof, and the contact surface 210 may be continuously formed along a length direction D1 of the reinforcing block part 200.

[0052] The contact surface 210 of the reinforcing block portion 200 contacts the outer surface of the tube body portion 100 in a surface contact manner, and when the tube body portion 100 resists atmospheric pressure, the contact surface 210 of the reinforcing block portion 200 forms a fixed boundary surface, thereby stably supporting the collapse load and bending load acting on the tube structure 10.

[0053] As an example, the contact surface 210 may be formed over the entire length direction D1 of the reinforcing block portion 200.

[0054] The installation width W and minimum installation height H of the reinforcing block portion 200 can be adjusted so that the tube structure 10 can resist a target bending load.

[0055] Here, the installation width W of the reinforcement block portion 200 is the width when the reinforcement block portion 200 is installed in the width direction D3, and the minimum installation height H is the minimum height when the reinforcement block portion 200 is installed in the height direction D2.

[0056] As an example, the reinforcement block portion 200 can have a central installation height HC that is a minimum installation height H on an extension line of the height direction D2 of the central axis O of the tube main body portion 100, and can have an end installation height HE that is greater than the minimum installation height H at the end in the width direction D3.

[0057] The reinforcing block portion 200 can satisfy the load condition of the bending load targeted by the tube structure 10 by varying at least one of the installation width W in the width direction D3 and the minimum installation height H in the height direction D2.

[0058] The reinforcing block portion 200 can have a minimum installation height H on an extension line of a portion corresponding to the central axis O of the tube main body portion 100 in a height direction D2.

[0059] The reinforcement block portion 200 has a central installation height HC, which is an installation height at the center portion in the width direction D3, which has a minimum installation height H, and an end installation height HE, which is an installation height at the end portion in the width direction D3, may be greater than the central installation height HC.

[0060] The reinforcing block portion 200 may have an arc-shaped contact surface 210 formed on the lower side thereof, the contact surface 210 being shaped to correspond to the upper side of the tube body portion 100 .

[0061] For example, the installation height of the reinforcing block portion 200 may increase from the center portion in the width direction D3 toward the end region in the width direction D3.

[0062] The tube structure 10 of the present invention has an advantage that the thickness of the tube main body 100 can be reduced while improving resistance performance against collapse load by reinforcing the rigidity of the tube main body 100 by installing a reinforcing block portion 200 therein.

[0063] Specifically, the tube structure 10 of the present invention has a reinforcing block portion 200 installed on the tube main body portion 100 to reinforce its rigidity, so that the tube main body portion 100 mainly resists the collapse load generated by the pressure difference between the internal pressure of the tube main body portion 100 and the external pressure, i.e., atmospheric pressure, and the reinforcing block portion 200 mainly supports the bending load generated by the weight of the tube structure 10 and the load of the traveling body, etc.

[0064] As a result, the reinforcing block portion 200 mainly resists bending loads, and the tube main body portion 100 mainly resists collapse loads, thereby reducing the thickness of the tube main body portion 100 and improving economy. Unlike the comparative example described above, the thickness of the tube main body portion 100 used in the tube structure 10 is constant, so there is no need to redesign the cross-section of the tube main body portion 100 in response to changes in the loading conditions of the bending load, which has the effect of providing design convenience.

[0065] In the case of the comparative example described above, when the pipe is manufactured according to the design standards of a normal pipeline and the diameter R increases to 4 m, the safety thickness that ensures the resistance performance against the collapse load as well as the safety factor increases to 28.4 mm, but there is a problem that significant restrictions are imposed on the production method of the tube main body 100 manufactured from a metal material such as steel.

[0066] In the tube structure 10 according to one embodiment of the present invention, the thickness of the tube main body 100 can be reduced to 25 mm or less while maintaining the same performance by using the reinforcing block portion 200. This eliminates the constraints on the production method of the tube main body 100 made of a metal material such as steel, unlike the comparative example described above, and has the effect of enabling the tube main body 100 to be produced economically and stably.

[0067] Below, with reference to Table 1 below, we will briefly explain comparative experiments using simulations etc. on central slackness of the first experimental example (steel tube + concrete block) corresponding to the tube structure 10 of the present invention and the second experimental example (steel tube) compared to the first experimental example, and their effects.

[0068] The steel tube applied to the first experimental example applied in this comparative experiment had a diameter (R) of 4 m and a tube thickness of 19 mm, and the steel tube applied to the second experimental example had a diameter (R) of 4 m and a tube thickness of 19 mm, and the concrete block had an installation width (W) of 1 m and a minimum installation height (H) of 0.2 m.

[0069] In both the first and second experimental examples, comparative experiments were carried out under the condition of a span of 24 m.

[0070] In the following Table 1, the dead load is a distributed load, and the second embodiment with the added concrete block has a larger dead load. The live load is the load of the running body, and is the same for the first and second embodiments.

[0071] The central slack in the first experimental example was 2.08, and the central slack in the second experimental example was 1.23. It can be seen that the first experimental example corresponding to the tube structure 10 of the present invention has the effect of reducing the central slack by about 41% compared to the second experimental example.

[0072] [Table 1]

[0073] The tube body 100 is made of a tubular member made of a metal material, the reinforcing block 200 is made of precast concrete, and the contact surface 210 may have a shape corresponding to the outer surface of the tube body 100. The tube body 100 is made of a tubular member having a circular cross section, and the lower surface of the reinforcing block 200 may have an arc-shaped contact surface 210 corresponding to the shape of the upper surface of the tube body 100.

[0074] At this time, the arc-shaped contact surface 210 of the reinforcing block portion 200 and the outer surface of the tube body portion 100 can come into contact with each other in a surface contact manner.

[0075] As an example, the tube main body 100 may be made of a steel material and may be configured as a tubular member having a diameter R of 3 m or more.

[0076] As another example, the tube main body 100 may be made of a steel material and may be configured as a tubular member having a diameter R of 4 m or more.

[0077] The reinforcing block 200 can be coupled to the upper side of the tube body 100 .

[0078] The contact surface 210 of the reinforcing block portion 200 can be in contact with the upper outer surface of the tube body portion 100 in a surface contact manner along the length direction D1.

[0079] When the tube is in a vacuum state with no internal pressure or has internal pressure equivalent to a vacuum state, and an external atmospheric pressure of 1 atmosphere is applied and a live load is applied as a running body moves inside the tube, deformation occurs concentratedly in the upper region of the tube main body 100.

[0080] Therefore, the tube structure 10 of the present invention uses a composite of steel and concrete, and the deformation concentrated on the upper part of the tube body 100 is fixed by the reinforcing block part connected to the upper part of the tube body 100, which induces changes in boundary conditions and makes it easier to control the deformation, thereby improving the load resistance performance of the tube structure 10 overall.

[0081] 6 to 8, the tube main body portion 100 has a plurality of unit tubes 100M arranged in succession along the longitudinal direction D1, and the reinforcing block portion 200 has a plurality of unit blocks 200M arranged in succession along the longitudinal direction D1, and the unit blocks 200M are installed across adjacent unit tubes 100M to connect the adjacent unit tubes 100M.

[0082] For example, the unit block 200M may be connected to the tube body 100 by a fastening portion 300.

[0083] As another example, although not shown, it goes without saying that the unit block 200M and the tube main body portion 100 may be connected by applying a bonding material such as an adhesive between the contact surface 210 of the unit block 200M and the outer surface of the tube main body portion 100.

[0084] A plurality of unit blocks 200M are arranged in series in the length direction D1, and adjacent unit blocks 200M may be connected to each other. Block connectors (not shown) may be installed between adjacent unit blocks 200M to connect the adjacent unit blocks 200M in the length direction D1.

[0085] Of course, the method of connecting adjacent unit blocks 200M is not limited to this method, and it goes without saying that various connecting methods for connecting structures made of precast concrete may be applied.

[0086] 7 and 8, the tube body 100 has a plurality of unit tubes 100M successively arranged along a length direction D1, and a reinforcing block 200 can connect adjacent unit tubes 100M.

[0087] The tube main body 100 has a plurality of unit tubes 100M connected together in the length direction D1, so that a moving path S along which the traveling body moves can be formed.

[0088] 6, the reinforcing block portion 200 includes a plurality of unit blocks 200M arranged in series along a length direction D1. The unit blocks 200M are different in at least one of the installation width W in the width direction D3 and the minimum installation height H in the height direction D2. Kuyu It may include knits.

[0089] As an example, the unit block 200M is a plurality of unit blocks having at least one different installation width W in the width direction D3 and a minimum installation height H in the height direction D2. Kuyu It may include knits.

[0090] Multiple unit blocks Kuyu Among the knits, a unit block having an installation width W and a minimum installation height H that meet the bending load conditions targeted by the tube structure 10 of the present invention is selected. Kuyu You can place nits.

[0091] For example, referring to FIG. 6, the block 200M may include a first block unit 200M-1, a second block unit 200M-2, and a third block unit 200M-3.

[0092] The first block unit 200M-1 may have a first installation width W1 and a first minimum installation height H1, the second block unit 200M-2 may have a first installation width W1 and a second minimum installation height H2 greater than the first minimum installation height H1, and the third block unit 200M-3 may have a second installation width W2 greater than the first installation width W1 and a second minimum installation height H2 greater than the first minimum installation height H1.

[0093] The tube structure 10 of the present invention is made up of a plurality of unit blocks, each of which has at least one of an installation width W in a width direction D3 and a minimum installation height H in a height direction D2 different from the other. Kuyu There is an effect that the load condition of the tube structure 10 can be satisfied by selectively selecting any one of the knits.

[0094] As an example, depending on the pre-calculated design requirements, a first unit block unit 200M-1 can be installed when the span is 20 m, a second unit block unit 200M-2 can be installed when the span is 25 m, and a third unit block unit 200M-3 can be installed when the span is 30 m.

[0095] Multiple unit blocks Kuyu By designing and standardizing the unit in advance to meet various load conditions, multiple unit blocks can be Kuyu Among the units, the unit block that meets the load conditions Kuyu By selecting and applying the knit, rapid and accurate mass production in a factory or the like is possible, which has the effect of improving the workability of the tube structure 10 of the present invention.

[0096] As an example, the reinforcing block portion 200 may have an installation width W in the width direction D3 within a range of 20 to 35% of the diameter R of the tube main body portion 100.

[0097] If the installation width W of the reinforcement block portion 200 is less than 20% of the diameter R of the tube main body portion 100, the tube main body portion 100 and the reinforcement block portion cannot contact each other in a sufficient surface contact manner, and therefore the tube structure 10 may not be able to stably support the collapse load and bending load acting on it.

[0098] If the installation width W of the reinforcement block portion 200 exceeds 35% of the diameter R of the tube main body portion 100, the weight of the reinforcement block portion 200 will increase excessively, increasing the amount of slack in the tube structure 10, which may result in inefficient cross-sectional performance.

[0099] As another example, the reinforcing block portion 200 may have a minimum installation height H in the height direction D2 in a range of 10 to 20% of the installation width W.

[0100] If the minimum installation height H of the reinforcement block portion 200 in the height direction D2 is less than 10% of the installation width W, it may become difficult for the reinforcement block portion 200 to stably support the collapse load and bending load acting on the tube structure 10.

[0101] If the minimum installation height H of the reinforcement block portion 200 in the height direction D2 exceeds 20% of the installation width W, the weight of the reinforcement block portion 200 increases excessively, increasing the amount of sagging of the tube structure 10, which may result in inefficient cross-sectional performance.

[0102] As another example, the reinforcement block portion 200 may have an installation width W in the width direction D3 that is in the range of 20 to 35% of the diameter R of the tube main body portion 100, and a minimum installation height H in the height direction D2 that is in the range of 10 to 20% of the installation width W.

[0103] In this case, as described above, the reinforcing block portion 200 can stably support the collapse load and bending load acting on the tube structure 10, and an excessive increase in the weight of the reinforcing block portion 200 can be prevented, thereby improving the cross-sectional performance of the tube structure 10.

[0104] The tube structure 10 according to another embodiment of the present invention may further include a fastening portion 300 .

[0105] The fastening portion 300 is installed to protrude from the outer surface of the tube body 100 and is fastened in a state of penetrating the reinforcing block portion 200 to connect the tube body 100 and the reinforcing block portion 200 .

[0106] The fastening portion 300 can bring the contact surface 210 of the reinforcing block portion 200 into close contact with the upper outer surface of the tube body portion 100 .

[0107] The fastening portion 300 can detachably connect the tube body portion 100 and the reinforcing block portion 200 .

[0108] The fastening portion 300 detachably fastens the tube body portion 100 and the reinforcing block portion 200, which has the effect of facilitating replacement of damaged components and facilitating maintenance of the tube structure 10.

[0109] In addition, the load conditions of the tube structure 10 can be met in a simple manner by dismantling and reinstalling the fastening portion 300, leaving the tube body portion 100, which mainly resists the collapse load, as it is, and replacing the reinforcing block portion 200 to suit the load conditions.

[0110] 3 and 4, the fastening portion 300 may include a first fastening member 310 and a second fastening member 330.

[0111] The first fastening member 310 is formed to protrude upward from the outer surface of the tube body 100 and can penetrate the reinforcing block 200 .

[0112] The first fastening member 310 may have a lower end joined to an outer surface of the tube body 100 and may extend in a height direction D2 and may pass through a slot hole 230 formed in the reinforcing block 200.

[0113] The first fastening members 310 may have upper ends each having a corresponding height.

[0114] For example, the first fastening member 310 may be a pin member or a bolt member formed to protrude upward from the outer surface of the tube body 100 .

[0115] For example, the first fastening member 310 may be a pin member or a bolt member that is integrally joined to the outer surface of the tube body 100 by welding or the like.

[0116] In a state in which the tube body 100 and the reinforcing block 200 are fastened by the first fastening member 310 and the second fastening member 330 , the first fastening member 310 may further protrude upward from the reinforcing block 200 .

[0117] This is because the minimum installation height H of the reinforcing block portion 200 can be varied depending on the load conditions of the tube structure 10, and a reinforcing block portion 200 having a thicker minimum installation height H can be stably installed.

[0118] After the first fastening member 310 and the second fastening member 330 are installed, the protruding portion of the first fastening member 310 (shown by dashed lines in Figures 3 and 4) can be removed and finishing work can be performed so that it does not protrude from the top surface of the reinforcement block portion 200.

[0119] The second fastening member 330 is detachably fastened to the first fastening member 310 , and can bring the contact surface 210 of the reinforcing block portion 200 into close contact with the outer surface of the tube body portion 100 .

[0120] The second fastening member 330 may be disposed in the inner groove 250 of the reinforcing block portion 200 in a state where the second fastening member 330 is fastened to the first fastening member 310 .
