Description

TECHNICAL FIELD

[0001] The present application relates to a rockfall buffering device, more particularly, to a rockfall stress buffering system, and to a building with buffering protection. BACKGROUND

[0002] Rockfall disasters often occur in high mountain and canyon areas. During the falling process of the rockfall, the buildings or roads near the slope may be damaged. It is generally believed that the passive protection of rockfall by using a shed tunnel structure is one of the most effective engineering measures, and similar shielding buildings can also play a protective role. A typical shed tunnel structure is composed of two parts: one is a reinforced concrete frame, and the other is a reinforced concrete roof. The support frame and the roof form an integral structure. In order to protect the roof of the building, a buffering layer is laid on the roof of the building. The buffering protection structure formed by the laid sand can absorb the impact of the rockfall and absorb part of the impact energy, thereby playing a certain protective role. However, due to the large impact of the rockfall, the buffering distance of the sand buffering layer for the rockfall is short, and during the falling process, the roof of the shed tunnel and other buildings may be damaged by the impact, so a new solution is needed to solve this problem.

DETAILED DESCRIPTION

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] This embodiment discloses a rockfall force buffering system, such as Figures 1-4 As shown, the structure includes several buffer components 1, each of which is located on the top of the building 3. Each buffer component 1 includes a buffer seat 7 that can be adjusted vertically for cushioning. The buffer seat 7 can perform vertical elastic cushioning action, and during the impact process, the buffer seat 7 can move downward elastically to absorb the impact, thereby achieving the buffering of the impact of falling rocks.

[0028] A buffer layer 2 is provided on the upper part of each buffer seat 7. The lower part of the buffer layer 2 is supported by each buffer seat 7, forming a continuous sheet-like structure on the upper part of the buffer assembly 1, thereby playing the role of catching falling rocks. Figure 3 As shown, the buffer layer 2 has a multi-layered structure, including a connecting layer 21, a first buffer layer 22, and a second buffer layer 23. The connecting layer 21 has a mesh structure, such as a mesh structure woven from a high-strength limiting material, and is locally connected and fixed to the upper part of the buffer seat 7. The second buffer layer 23 is a flexible rubber material laid on top of the connecting layer 21, and is fixedly bonded to the connecting layer 21 and the first buffer layer 22, so that the connecting layer 21 and the first buffer layer 22 are connected to form a whole, which can buffer and bear falling rocks. Moreover, the buffer layer 2 is a buffer particle layer, such as a layer of soil, which can form a good impact protection on the surface of the buffer layer 2.

[0029] During the impact of falling rocks, when the rock hits the upper part of the buffer layer 2, the impact layer will indent downwards, thus bearing the weight of the falling rock. Simultaneously, multiple buffer components 1 support the lower part of the impact layer. The up-and-down movement of the buffer components 1 absorbs the impact of the falling rock, increasing its protective effect. After being impacted and indented, the buffer layer 2 increases the contact force between itself and the falling rock, reducing the pressure per unit area and thus minimizing the destructive impact of the rockfall.

[0030] like Figure 4As shown, the buffer assembly 1 further comprises a base 4, a support rod 5 and a support spring 6, the base 4 is fixedly installed on the top of the building 3; a through hole one 42 is formed in the middle of the support rod 5, the support rod 5 penetrates the base 4 up and down through the through hole one 42 and forms an up-down guide sliding structure. The upper end of the support rod 5 is connected with a buffer seat 7, and the base 4 and the buffer seat 7 can form an up-down guide sliding structure through the support rod 5. The support spring 6 is sleeved outside the support rod 5 and elastically abuts between the base 4 and the buffer seat 7, and can be elastically supported between the base 4 and the buffer seat 7 through the support spring 6, thereby playing a buffering and absorbing role.

[0031] In order to enable the support rod 5 to freely stretch and retract at the upper part of the building 3, an appropriate hole or cavity can be formed at the corresponding position of the building 3 to accommodate the support rod 5, so that the support rod 5 can smoothly realize the lifting and retracting action.

[0032] In addition, the buffer assembly 1 further comprises a plurality of slide rails 9 and inclined rods 8, which are one-to-one corresponding and form an amplitude-shaped distribution structure on the outer periphery of the base 4, forming a ring-shaped uniform distribution.

[0033] Among them, the slide rail 9 is arranged on the outer periphery of the base 4 and distributed in a spoke shape. The slide rail 9 is provided with a slide 91 therein, and the direction of the slide 91 is along the radial direction of the base 4; a sliding block 92 is slidably connected in the slide 91, and the sliding block can be adjusted in sliding in the slide 91. The inclined rod 8 is connected between the buffer seat 7 and the slide rail 9, and a plurality of inclined rods 8 form a ring of buffer support components on the outer periphery of the support rod 5, thereby maintaining the lifting stability of the buffer assembly 1 and increasing the strength of the impact resistance process.

[0034] The upper end of the inclined rod 8 is connected to the outer periphery of the buffer seat 7 through a spherical joint one 81, and the lower end of the inclined rod 8 is connected to the sliding block 92 through a spherical head structure two, and the spherical joint can realize the swing adjustment of the spherical head, thereby maintaining the smoothness of the action of the upper and lower ends of the inclined rod 8. When the buffer seat 7 is subjected to a downward pressure process, the lower end of the inclined rod 8 will move towards the outer periphery of the base 4, and the sliding block 92 will be laterally displaced to decompose the impact force received by the buffer seat 7, thereby playing an additional buffering protection role.

[0035] In addition, a buffer spring 10 is provided between the slider 92 and the base 4. The number of buffer springs 10 corresponds one-to-one with the inclined rod 8. The buffer spring 10 can provide elastic compensation for the inclined rod 8, thereby improving the buffering effect of the buffer seat 7 under pressure. For this buffer spring 10, one end of the spring acts on the slider 92, and through elastic deformation, it elastically restricts the slider 92 from sliding outward. Specifically, the buffer spring 10 can be a tension spring, with its two ends connected to the slider 92 and the base 4 respectively, thereby playing a role in elastically restricting the slider. The connection position of the buffer spring 10 can also be not connected to the base 4, and it can play a role in elastic support when connected to other positions.

[0036] Furthermore, this embodiment also discloses another rockfall force buffering system. Based on the above embodiment, the structure of the buffer component 1 is further designed, as detailed below. Figures 5-8 Please provide an explanation.

[0037] like Figure 5 , 6 As shown, the base 4 has a hollow structure, and a hollow adjustment cavity 40 is provided inside the base 4. A swing seat is provided inside the adjustment cavity 40, and the circumferential contour of the swing is slightly smaller than the inner circumferential contour of the adjustment cavity 40, so that the swing seat can achieve horizontal movement adjustment within the adjustment cavity 40.

[0038] The upper end of the support rod 5 is supported by the buffer seat 7, and a ball joint connection structure can also be adopted. The support rod 5 and the buffer seat 7 are connected by a ball joint 51, which allows the buffer seat 7 to be adjusted by ball joint swing. By swinging the ball joint of the buffer seat 7, the orientation of the upper part of the buffer seat 7 can be adjusted, thereby adapting to the impact of falling stones at different positions on the upper part of the buffer layer 2.

[0039] A through hole 42 is provided on the upper part of the base 4, which is slidably adapted to the support rod 5. Additionally, a through hole 43 is provided on the lower part of the base 4, allowing the lower end of the support rod 5 to extend smoothly downwards. Furthermore, a central hole 111 is provided in the adjusting seat 11, with a diameter larger than that of the support rod 5, allowing the adjusting seat 11 to fit around the support rod 5 and to be adjusted horizontally.

[0040] In addition, several through holes 3 are provided on the outer periphery of the base 4, and the number of through holes 3 corresponds to the number of slide rails 9. The buffer spring 10 is a tension spring. During installation, one end of the buffer spring 10 is connected to the slider 92, and the other end passes through the corresponding through hole 3 and is connected to the adjusting seat 11, thereby achieving an elastic buffering effect between the slider 92 and the adjusting seat 11. By moving the adjusting seat 11 horizontally, the adjusting seat 11 can achieve a horizontal offset, thereby allowing the inclined rods 8 on both sides of the base 4 to form differential sway. In each set of buffer components 1, the tilt angle of each inclined rod 8 can be adjusted differently, thereby forming different states of force adjustment during the force application process.

[0041] Furthermore, since the adjusting seat 11 connects all the buffer springs 10 together, it can maintain the force stability of the buffer springs 10. When the downward angle of the inclined rod 8 on one side is large, the buffer spring 10 at that side can drive the adjusting seat 11 to move towards that side. Moreover, when the adjusting seat 11 moves towards that side, it can play a role in elastic force compensation between the buffer springs 10 on both sides. When the buffer seat 7 swings in different directions, it can play a role in buffer support. Through the buffer springs 10 at different positions on both sides, it can stabilize the inclined rods 8 on both sides to ensure the force stability of both sides of the buffer assembly 1.

[0042] like Figure 6 , 7 As shown in Figure 8, a retaining ring 112 is fixedly connected to the upper part of the inner circumference of the central hole 111, and an annular seat 113 is slidably connected to the lower part of the inner circumference of the central hole 111. The outer circumferential contour of the annular seat 113 can slide up and down within the central hole 111 for adjustment. Furthermore, a connecting spring 115 is elastically connected between the annular seat and the retaining ring 112. The upper and lower ends of the connecting spring 115 can connect the retaining ring 112 and the annular seat 113, keeping the annular seat 113 in a relatively fixed position, thereby providing an elastic buffering effect through the connecting spring 115.

[0043] The annular seat 113 is fitted around the outer periphery of the support rod 5, and a tapered flare 114 is provided at the lower end of the inner periphery of the annular seat 113. A limiting block 52 is fixedly connected to the lower end of the support rod 5. The upper part of the limiting block 52 is a tapered portion 521, which adapts to the tapered flare 114. When the limiting block 52 moves upward, the tapered portion 521 and the tapered flare 114 are matched to each other, which can play a guiding and limiting role. The lower part of the limiting block 52 is a straight cylindrical portion 522, which is slidably matched with the lower end of the central hole 111. The straight cylindrical portion 522 can extend into the central hole 111. When the straight cylindrical portion 522 moves upward and extends into the central hole 111, the straight cylindrical portion 522 and the central hole 111 will play a limiting role, thereby locking the horizontal movement of the adjusting seat 11.

[0044] like Figure 8 As shown, when the buffer assembly 1 is in its initial state, the support spring 6, through its elastic action, can lift the buffer seat 7 upwards, thereby maintaining the buffer seat 7 in a high position. The limiting block 52 at the lower end of the support rod 5 extends into the central hole 111 of the adjusting seat 11. Through the guiding and limiting action between the limiting block 52 and the central hole 111, it can play a limiting and guiding role. The adjusting seat 11 is limited by the supporting rod 5 and the limiting block 52, which can restrict the adjusting seat 11 to a central and stable position, thereby maintaining the uniformity and stability of the various inclined rods 8 on the outer periphery.

[0045] like Figure 6 As shown, when a falling rock impacts downwards, it exerts impact pressure on the upper part of the buffer layer 2, which in turn exerts impact pressure on the buffer seat 7. During the initial impact process, the limiting block 52 will act as a guide and limiter within the central hole 111. When the impact of the falling rock is greater, it will cause the support rod 5 and the limiting block 52 to move downwards. The limiting block 52 moves downwards and extends out from the central hole 111, forming a... Figure 6 As shown in the diagram. After the limiting block 52 extends out of the central hole 111, the adjusting seat 11 can smoothly swing laterally within the adjusting cavity 40, thereby enabling the tension springs on the outer periphery of the adjusting seat 11 to produce adaptive adjustment movements.

[0046] After the impact of the falling rock, the buffer seat 7 will elastically return upward. During the elastic return process, the conical part 521 at the upper end of the limiting block 52 can be matched with the conical flare 114 at the lower part of the annular seat 113. The conical part 521 and the conical flare 114 will be guided and matched with each other. The conical structure can drive the adjusting seat 11 to move towards the central position of the adjusting cavity 40. Through the two conical structures, an automatic centering action is achieved, thereby maintaining the automatic return of the adjusting seat 11 and keeping the entire buffer assembly 1 in a stable state.

[0047] This embodiment describes a building facility with buffer protection, such as... Figure 1 , 2 As shown, the structure includes a building 3, which is constructed on a mountain slope. For example, the building 3 may be an extension of a highway tunnel or a tunnel entrance. A distributed rockfall buffer system, as described in the above embodiment, is installed at the top of the building 3 to buffer and protect the upper part of the building 3 from falling rocks. In this distributed rockfall buffer system, the buffer components 1 form a uniformly distributed structure, which can form multiple points on the top of the building 3 to achieve buffer support. The buffer components 1 support the buffer layer 2, thereby forming a good buffer protection effect on the top of the building 3.

[0048] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
