Description

533256 V. Description of the invention (1) [Field of the invention] The present invention relates to an impact absorption grid and an impact absorption method capable of absorbing the impact force of falling rocks, avalanches, and avalanche soil and sand. [Background of the Invention] A general impact buffer grid is composed of a pillar and a protective net, and the pillars are erected at a certain interval. The protective net is horizontally arranged between the pillars and is made of rope. Currently known protective nets include "S 1 iptype (sliding type)" which uses friction resistance type buffers and absorbs impact by the sliding resistance between the rope and the buffers and "N 〇s 1 iptype (no Slide type) ". For the sliding type mentioned above, please refer to "Figure 17". It is known that a cushion e is provided at the crossing portion of the crossing rope d, and it is arranged across each pillar f as shown in "Figure 18". Most forms of holding the end and the middle of the horizontal rope g between the buffers e, and holding both ends of the horizontal rope g on the buffer between the units f and f as shown in "Figure 19" The form of e. These impact buffer grid systems have the following problems. 1. Compared with the sliding type, the non-sliding type not only has lower impact absorption performance in the protective net, but also its grid body is designed to be large and have a large weight, which makes it difficult to absorb shock at a higher cost. 2. Compared with the non-sliding type, the sliding net has a large amount of deformation during the impact. Therefore, the installation site of the grid cannot be used in various transportation facilities (roads or railways) and near residential areas. Place, so its installation site is subject to restrictions. In addition, because a large number of buffers are used, the buffer

533256 V. Description of the invention (2) Setting up the equipment and holding the rope requires a lot of procedures and time. 3. These two types of common problems include heavy protective nets, and the rope diameter that can be used is limited, so the high-speed improvement of their impact performance is limited. 4. Because the spacing of the protective nets is set at a predetermined interval, most horizontal ropes are arranged in a multi-segment configuration. It is necessary to pay attention to the measures to prevent openings between horizontal ropes. So far, no appropriate technology has been proposed. Based on the above, the present invention is designed in view of the above problems, and designes an impact absorption grid and an impact absorption method of an impact absorption technology that exhibits high impact absorption performance while regulating the opening state between the ropes to be constant. [Objective and Summary of the Invention] The main object of the present invention is to provide an impact absorbing grid and an impact absorbing method, which can increase the impact absorbing performance by hanging a protective rope loop with a buffer function between the pillars. According to the shock absorbing grid and shock absorbing method disclosed in the present invention, the shock absorbing grid and the shock absorbing method are composed of a plurality of supports and a plurality of protective rope loops, wherein two pillars are erected at a predetermined interval, and the protective rope loop is a rope material, and its length It is at least equal to the length between the two pillars, and is held near the end by a buffer to have a buffer function, and the protective rope loop is rolled into a plurality of sections between the two pillars. The protective rope loop also has the function of cushioning, and therefore increases the shock absorption performance. In order to further the purpose, structural features and functions of the present invention

533256 V. Description of the invention (3) It is understood that the detailed description with the illustrations is as follows. [Detailed description of the embodiments] The following describes the implementation modes of the present invention with reference to the illustrations. [Implementation Mode 1 of the Invention] (I) Structure of the shock absorbing grid ^ "Figure 1" is a side view of the partially cut shock absorbing grid 1 0 when the mountain side is viewed from the valley side. The shock absorbing tree 10 of the present invention is provided at a predetermined interval between the main 20 and the pillars 20 and 20, which are wound in a rope loop shape 30 and near the end of the protective rope loop 3 (). The friction resistance tool 40 and the connecting material 50 spanning each of the protective rope loops 30 are basic I-scale elements. Protection Ϊ ΐ It is explained that the upper part of each pillar 2G is connected by a horizontal rod 6G, and a rhombus-shaped barbed wire is installed on one side of the 30 groups of 4 rope loops. The horizontal bar 60 and barbed wire 70 are omitted. poor. However, it is also possible to (two) pillar soil punching steel ΐ 2 zoom in Λ to reveal that the 'pillar 20 series can be steel pipes, concrete' Β This concrete column or elastic pillar, etc., as long as the tt 3 〇 roll reservation The surface may be a curved surface. 7 make 4 anti-cord loops up 2 i support i, there are many fat-shaped positioning protrusions in the face length direction history. ; The σ 疋 position protrusion 2 1 can be prevented from slipping when inserted into the protective rope loop 30. The preferred one is to form a narrower pitch with respect to the support protrusion 21, and the positioning vehicle for the f extension is suitable. Corresponds to the fall of the trail

533256 V. Description of the invention (4) I property becomes better. Specifically, the size of the expected falling rock, the type of avalanche and falling rock, etc. are considered, and the arrangement interval of the protective rope loop 30 in the up and down direction is appropriately selected. It is also possible to provide a depression instead of a protrusion. In addition, the lower part of the pillar 20 is supported on the ground and made of concrete. It is not necessary to fall, but it can be supported by a hinged structure. When the pillar 20 is supported in a pourable state, a buffer device must be interposed therebetween and it must be combined with a control rope. (3) Protective rope loop The protective rope loop 30 is made of very strong tensile endurance, such as PC steel wire or better rope than PC steel wire. It is placed between the adjacent pillars 20 and 20 in a horizontal direction. It is rolled up in a loop-like manner without slackening, and the overlapping portions of j are attached to both ends of the rope by holding them with a buffer 40 or the like. At the end of the rope. There are also stoppers to regulate their release from the bumper 40. ^ 31 ^ 31〇 31 ^ 31ϋ, which extends from the holding position of the buffering device 40 of each protective rope loop 30. It is possible to determine the sUp distance of the protective rope loop 30 when impacted. Pillar iSΓίΐ, in the above case, in addition to the pillar of the terminal, the protective rope loops 30 and 30 are hung from both directions on the pillars 20 A f 2 0 located at the terminal. It is related to the protection rope loops 30 and 30 around the wrong rope ^ 10,000 w and the rope loops 30 are rolled in a chain. In order to ensure that it can form the same level of impact absorption performance as the pillar grid between the pillars: the familiar kiss of the rope ° mouth, forming a protective rope loop 3 0 533256 5. The rope system of the invention description (5) can be configured multiple times Since the force can be transmitted and dispersed in the formation range of the rope loop, the rope diameter of the protective rope loop 30 can be reduced. (4) The buffering device, the buffering device 40, is the overlapping portion of the holding rope loop 30, which can allow the rope to slide and attenuate its impact when the tensile force acting on the protection rope loop 30 exceeds the frictional resistance of the holding portion. A device of force.苐 3 "and" 4 "illustrate the cushioning device 40, which includes: a restraint plate 4 1 formed by cross-folding the center of an elastic steel plate into a cross-section bulb shape; and interposed in the restraint plate 41 Dividing the internal space into two and partitioning the partition board 4 2 to define the accommodation space of the rope; and binding the free end of the restraint board 41 in the contraction direction ', the protective rope is looped by the restraint board 41 and the partition board 4 2 Bolts 4 3 and nuts 4 4 that are connected and connected by 3 0. In addition, the binding force of the bolt acting on the restraint plate 41 is made equal to the restraint force acting on the two ropes, and the restraint plate 41 and the partition plate 42 are brought into contact with each other by crimping the peripheral surface of each rope. The frictional resistance of the part will attenuate the tensile tension acting on the rope. The cushioning tool 40 shown in the figure is a sheet and formed into a plate body. By this, the elasticity of the restraint plate 41 can be used to restraint with an equal force, and at the same time, compared with a weight of several tens of kilograms The conventional cast iron buffer device is smaller and lighter, so it has the advantage of being easier to handle and assemble. In addition to using the items shown in the figure as the buffer 40, it is also possible to use a known frictional resistance type formed by bolts that can hold most of the overlapping portion of the protective rope loop 30 and connect these plates with bolts. Buffers, etc.

533256 V. Description of the invention (6) (5) Connecting material The connecting material 50 is a wavy, thin band or rod-shaped element, and has a length that can be placed on most protective rope loops 30. The arrangement of the connecting materials 50 across most of the protective rope loops 30, 30, ... can maintain the setting interval of each protective rope loop 30, and can transmit strength to each other between adjacent protective rope loops 30 , And can prevent the ropes around the protective rope loops 30 from penetrating, and the impact space (range) of the protective rope loops 30 arranged in multiple sections can be divided into smaller and easy to resist smaller impact objects. The reason why the connecting material 50 is wavy, as shown by the arrow in the vertical direction in "Figure 6", is that it can absorb the impact energy by deforming in the direction of extension of the connecting material 50 when it is impacted. When the wavy portions between the adjacent protective rope loops 30 extend into a straight line, the interval between the protective rope loops 30 will be the largest, and the opening effect above this level can be regulated between the respective protective rope loops 30. Therefore, the wavy shape of the connecting material 50 is generally formed continuously throughout the entire length, as shown in this example, but it is advantageous, but a wavy portion may be formed on a portion of the linear connecting material 50. The material of the connecting material 50 can be a plastically deformable material such as steel or an elastically deformable material such as spring steel, and the material is not particularly limited. When the connecting member 50 is installed, as shown in the "figure 5", the lower end of the branching member 5 1 suspended from the horizontal rod 60 can be connected with the upper ends of the connecting members 50 and 50, facing each other. The branching material 51 and the connecting materials 50 are integrally formed of continuous materials, but they may be formed separately or combined by welding, as shown in the figure, by

V. Description of the invention (Ό Receiving plate 5 which is arranged in a zigzag shape on the inner side and also serves as a space-retaining material 5 and U bolts 5 3 and nuts 5 4 which are capable of accommodating the protective rope loop 30 0 Can also ° That is, bolt holes must be drilled in the ternary overlap of the connecting material 50, the branch material 51 and the receiving plate 52. Insert the U bolt 5 3 of the receiving rope into these two pieces 5 0, 5 1, 5 2 and the nut 5 4 to conclude. About the protective rope loop 3 except the uppermost position ○ As shown in "Figure 6", the combination of the rectangular receiving plate 55 and the U bolt 53 and the nut 54 is supported. = Intersecting part of the rope and the connecting material 50 in multiple stages. By accommodating each of the ropes of the protective rope loop 30 in the valley portion of the connecting material 50 and forming a tie with the U bolt 53, it can be ensured that it is generated with the rope peripheral surface In the case of a large contact area, the contraction force can be set if the relative force can be applied to any one of the rope and the connecting material 50 in excess of the contraction force. Energy is absorbed by its sliding impedance. When the present invention is subjected to various impact forces F acting on the impact absorption grid 10, see "Seventh The impact direction of the impact force F is from the upper part to the lower part in the figure. (1) In the early stage of the conflict, an impact force acts on the side of the protective rope loop 30 arranged in a plurality of sections via the barbed wire 70 and the front side is provided with a buffer 40 F. The impact force F is transmitted to the protective rope loop through the coiled part on the pillar 20. The slow-pressing force 4L is along the full length of the protective rope loop.

Page 10 533256 V. Description of the invention (8) In addition, because the connecting material 50 and the protective rope loops 30, 30 arranged in a plurality of sections intersect, the area is divided into a very small range, so the impact force can be F is stopped, and even small falling rocks can make it impenetrable. This tensile tension will not cause the rope to slip under the range of the holding force of the buffer 40 of the protective rope loop 30, so the rope length of the protective rope loop 30 will not change. Adjacent protective coils 3 0 and 3 0 can transmit power through the pillar 2 0, so the impact force F is transmitted to the protective rope loops 3 0 and pillars 2 which do not directly act, and most of the protective rope loops 3 0 Decentralized support with most pillars. (2) Absorption of impact The deformation strength of the wire mesh 7 and the protective rope loop 30 can absorb a certain degree of impact force F, but the impact absorption grid 10 of the present invention mainly absorbs the impact by most of the following impact absorption effects Force F. (1) The shock absorption effect is generated by the deformation of the connecting material. The impact force F is generated by the force of 30 intervals between the upper and lower protective rope loops. When this force exceeds the deformation strength of the connecting material 50, as shown in "Figure 6", the connecting material 50 is deformed and stretched for a certain length. The deformation resistance when the connecting material 50 is stretched can absorb the impact force F. As the connecting material 50 is stretched, the distance between the upper and lower protective rope loops 30 and 30 is expanded to a certain extent, and when the connecting material 50 is stretched to the maximum, the interval of the protective rope loop 30 is regulated. for sure. (2) Impact absorbing effect caused by the sliding of the connecting material and the rope The impact force F will exert the force of the staggered rope of the protective rope loop 30 and the connecting material 50 in a cross relationship along the rope.

‘JO

When the resistance t exceeds the binding force of the protective rope loop 3 to the right, the rope / connecting material 50 crosses right and absorbs the impact force F. A sliding movement occurs between the two sides, whereby the shock absorbing effect of (3) the cushion in the sliding ring The right impact force F exceeds the grip of the cushion 40. ^ ^ 3. Of ropes and buffers 4. When sliding force will be generated: the frictional resistance constituting the protective rope effectively absorbs the impact force F (SllP) ', and the impact absorption fF generated by sliding the sliding resistance between the protective rope loop and the pillar is used as At the beginning of the sliding movement between the rope and the buffer 40, the length of the rope of the protective rope loop 30 increases, and the coiled part of the side of the protective rope loop 30 and the pillar 20 also slides. The frictional resistance of the entangled portion can also absorb the impact force F. Most of the above-mentioned shock absorption effects can also be used in the case where the excess length portion 3b3b becomes shorter and the stopper abuts against the buffer 40. (3) Other functions of the connecting material In addition to the effect of absorbing the impact force F, the connecting material 50 also has the following effects. As shown in "Figure 8", as the protective rope loop 30 is stretched, a pair of connecting materials 50 and 50 are pulled by the ropes in opposite directions, respectively, and deformed in the horizontal direction. As a result, a pair of connecting materials 50 and 50 which were overlapped before being hit was pulled apart, and the zones of each of the protective rope loops 30 and 30 arranged in multiple stages became smaller. Therefore, when the impact force F is falling, it can prevent subsequent small drops

Page 12 533256 V. Description of the invention (ίο) The transmission of the stone is similarly buffered. "Figure 9" is a cross-sectional view of the grid body when the protective rope loops 30 and 30 arranged in multiple stages are stretched and connected sideways. Among the protective rope loops 30 and 30 arranged in multiple sections, the connecting material 50 arranged on the right side of the front side of the figure is abutted against the ropes 3 0 b and 3 0 c on the back side and regulates the pull of these degrees or more Out. In addition, when the rope 30a forming the front side of the protective rope loop 30 is pulled out sideways, it rarely moves horizontally horizontally and moves in one of the vertical directions. Therefore, the ropes 30a on the front side are inserted between the ropes 3b and 30c on the rear side and the ropes are arranged in the horizontal direction at a smaller interval than the distance between the protective rope loops 30. That is, the arrangement intervals of the ropes 3 a and 30 b are substantially narrower than before the impact force F is applied. The above description is based on the front-side rope, but other ropes can also be inserted between the ropes when the back-side rope is used as a reference. When the arrangement interval of the ropes in the horizontal direction becomes smaller, the load on the wire mesh 70 can be reduced, and the catching ability of the small-caliber falling rocks becomes better. (4) Reasons why the amount of the rope to be pulled out is small Also, the following description explains that the impact absorbing grid 10 of the present invention can have a small amount of sideways opening to the protective rope loop 30. "Fig. 10" is a model diagram of a single type shock absorbing grid for comparison, which is composed of a rope fixed at one end of each pillar, and the center of the overlapping portion of the two ropes is held by a buffer (not shown). In the same figure (A) is the state before being hit, and (B) is the state after being hit. Assume

Page 13 533256 V. Description of the invention (π) For example, when the distance L between the pillars is 6 m, and the distance I of the remaining length of the rope is 0.5 m, the amount of rope out after the impact △ y 1 becomes 1 . 2 5 m. "Figure 11" is a model diagram of the shock absorbing grid of the present invention in which a protective rope loop is hung between the pillars. In the same figure, (A) is the state before being hit and (B) is the state after being hit. For example, when the distance between the pillars is 6 m, and the distance I of the remaining length of the rope is 0.5 m, the amount of rope opening △ y 2 after being hit becomes 0.85 m. However, to simplify the calculation, the length of the loop of the protective rope loop is ignored. In this way, when the amount of sliding (energy absorption) is the same, the amount of rope out is smaller than that of the inventor's protective rope loop 30, which is very important when the impact absorption grid 10 is placed on the road. advantageous. In addition, compared with a single-type article, the impact absorbing grid 10 of the present invention can reduce the caliber of the rope, and also has better conditions such as shear resistance. [Embodiment Mode 2 of the Invention] The following is a description of other embodiment modes. However, in the description, the same parts as the foregoing embodiment mode 1 are denoted by the same symbols, and detailed descriptions thereof are omitted. Instead of using the branching material 51, a pair of connecting materials 50 and 50 can be attached to most of the protective rope loops 30 and 30. By doing so, the branching material 51 can be omitted, and the total number of components can be reduced and the installation can be simplified. Also, in the foregoing embodiment 1, the case where most of the protective rope loops 30, 30 are used as a set of a pair of connecting materials 50, 50 on both sides of the front face and the back face, but Set on the front (hitting surface) or back of the protective rope loop 30

533256 V. Description of Invention (12) Any one of the (12) faces may be used. It is suitable for applications where the impact force F is relatively small. Moreover, the connecting material 50 is not limited to one continuous sheet, and it may be arranged by dividing into a large number of connecting materials along the height direction of the grid body. By dividing the connecting material 50, the portability and assemblability can be improved. Alternatively, the connecting material 50 may be arranged in an oblique direction and attached to the protective rope loops 30 and 30... The configuration of the connecting material 50 can be arranged by combining the oblique directions on one side of the protective rope loops 30, 30, ..., or by alternately changing the oblique direction like a wave. It is also possible to arrange the protection rope loops 30, 30 by changing the oblique direction of the front and back surfaces. [Embodiment Mode 3 of the Invention] The protective rope loop 30 can be in a roll-up mode as shown below. The arrangement of the connecting material 50 is the same as the previously described implementation mode. "Figure 12" is another type of arrangement of the protective rope loop 30 between the pillars 20 and 20 in a flat splayed shape. In this example, compared with the implementation type 1, it can make the winding angle (rolling length) of the protective rope loop 30 relative to the pillar 20 longer, so it can increase the sliding resistance during impact and improve the impact. Absorption performance. Also, as shown in "Figure 13", when the protective rope loop 30 is wound on one or more turns on the entire circumference of the pillar 20, the sliding resistance of the protective rope loop 30 and the pillar 20 can be increased. And improve its shock absorption performance. Also, "Figure 14" shows two rolls at the same height between pillars 20 and 20.

Page 15 533256

In this example, only by increasing the number of winding loops of the protective rope loop 30, the dispersion of the impact force becomes better. "1 j make the 16th figure" is the other type of protrusions 22 provided on one side of the pillars 20 and 20, and adjacent protrusions 22 and 22 = the other type of ring 3 0 . Ho 1 square rope

In this example, it is revealed that when a circle 3 0 is rolled on a protrusion 2 2, a spectrum 2 around the pillar 20 is guarded 2 circles 3 0, 3 0 on a protrusion 21. Alternatively, it may be set to the state of the common protrusion 2 丨. & ,,,, and, in order to prevent the protective cord loop 3 from falling off during impact, the protective cord loop 3 is arranged on the side opposite to the impact direction of the pillar 20 and the protective cord loop 3 is formed, and the bulge is formed on the two parts of the protrusion 22. You can also do it. The use of the protective rope loop 30 on the shock absorbing grid has the following advantages. 1 · Because of the suspension of the protective rope loop with buffer function between the 20 and 20 pillars

3 0 ′ can improve the dispersion of the impact force and the shear resistance, and can provide an impact absorption grid with a higher impact absorption performance. 2 · Compared with a grid body with a flat protective net, it can reduce the opening amount of the protective rope loop 30, so it is more advantageous for installation in a field with a limited opening amount such as a road. 3. Because the number of buffers 40 can be used less, the construction fence can be greatly reduced.

Page 16 533256 V. Description of the invention (14) The time, labor and economic burdens required by the body. 4 · Because the dispersion of the impact force is proportional to the number of rolls of the protective rope loop 30, the impact absorption performance of the whole grid body can be greatly improved. [Implementation Mode 4 of the Invention] The above is the description of the case where the connecting material 50 is provided on the shock absorbing grid composed of the protective rope loops 3 0, 3 0 that are wound between the pillars. A variety of known shock absorbing grids with a large number of ropes straddling between the pillars can also be applied. In this case, 'a plurality of ropes arranged in a plurality of stages are arranged with wave-shaped connecting members toward the crossing direction of the ropes, and at the same time, the ropes arranged in a plurality of stages are connected with each of the connecting members to form a crossing portion. Regarding the fact that the opening state between the ropes is fixed by the connecting material and the shock is absorbed by the buffering effect caused by the plastic deformation of the connecting material and the sliding resistance of the rope, the same as the aforementioned embodiment. This example is an existing or newly installed shock absorbing grid that can be applied to a plurality of ropes with multiple sections arranged between the pillars, so it is quite versatile. Moreover, the impact absorption performance can be greatly improved only by disposing the connecting material. [Achieved effect] The method, according to the impact absorption grid and impact absorption method disclosed in this meal, has the following effects: Improve the impact buffer function of the protective rope loop, because of the impact absorption grid. Month 丨 Broken Endurance ’provides shock absorption performance] 2. Compared to the case of a grid body with a flat protective net, it is possible;)

Page 17 533256 V. Description of the invention (15) The amount of opening of the protective rope loop is very advantageous for places such as roads where the amount of opening is restricted. 3. Because the number of buffers is less, it can greatly reduce the time, labor and economic burdens required to construct the fence. 4. Because the dispersion of impact force increases in proportion to the number of coils of the protective rope loop, the impact absorption performance of the whole grid body can be greatly improved.

5. It can prevent the opening of the rope only by arranging wavy connecting materials on most ropes or protective rope loops. At the same time, it can effectively absorb the impact by the plastic deformation of the connecting materials. The above are only the preferred embodiments of the present invention, and are not intended to limit the scope of the present invention; that is, all equivalent changes and modifications made in accordance with the scope of the patent application for the present invention are covered by the scope of the patent for the present invention. .
