Description

Technical Field

[0001] The invention relates to a light-weight house earthquake-resistant structure, and in particular to an earthquake-resistant structure. Background Art

[0002] The seismic resistance of modern house structures, especially those built with lightweight steel and green steel, especially the stability of longitudinal and lateral vibrations, is an important indicator to measure whether the structure is stable. Due to structural problems, lightweight houses suffer the greatest damage in earthquake disasters, especially on the top of the house. Some buildings use glass house structure roofs for aesthetics and lighting. In this way, the glass can easily fall or shatter during the vibration of the house.

[0003] In the research and development cooperation of our company, we found that the top of the light steel structure, especially the glass house whose top structure is not flat, is more likely to be damaged in an earthquake. After research, it was found that in the early stage of an earthquake or a minor earthquake, the main vibration is up and down. The earthquake gradually changes from longitudinal waves (up and down vibration) to transverse waves (left and right shaking), and small earthquakes may have longitudinal waves and then turn into small-level transverse waves. In the design of many existing shock-absorbing structures, the structures that avoid longitudinal and transverse waves of earthquakes are designed together. This makes the shock-absorbing structure shake left and right when it vibrates up and down due to a small amount of transverse waves when it is subjected to longitudinal waves of earthquakes, which will more or less affect the stability of the building.

[0004] This requires a shock-absorbing structure that is stable and flexible and can control the vibration direction of the building to solve the above problems. Summary of the invention

[0005] The present invention aims at the problem that when a building is subjected to longitudinal wave vibration, left-right resonance is generated due to a small magnitude of transverse wave in the existing building anti-seismic structure, resulting in premature damage to the building, and proposes an anti-seismic structure to solve the above problem.

[0006] The solution of the present invention is achieved as follows: an earthquake-resistant structure, comprising a top plate and a bottom, characterized in that an earthquake-resistant mechanism is arranged between the top plate and the bottom, the earthquake-resistant mechanism comprises a telescopic kit, a spring member is arranged on the periphery of the telescopic kit, the telescopic kit comprises a fixed rod member fixed to a base, and an upper rod member slidably connected to the fixed rod member, the upper rod member can move up and down in the fixed rod member;

[0007] A top plate is fixed on the upper part of the upper rod, a spring member is provided between the top plate and the base, and the maximum shrinkage of the upper rod when the rod is fixed is the maximum compression of the spring member;

[0008] The base is installed on the lower base. The base is a circular structure. The area of ​​the lower base is larger than that of the base. When the base is not subjected to external force, the center of the base and the center of the lower base coincide. A bottom sleeve is also provided on the outside of the lower base.

[0009] At least four limiting columns are arranged on the side of the base, and limiting holes are arranged on the side of the base, and the limiting columns are arranged in the limiting holes; a reset member is arranged on the outer side of the base, and the reset member is connected to the contact plate through a connecting member, and the limiting column is arranged on the connecting member;

[0010] The contact plate is arranged at the lower part of the upper rod. When the upper rod drops to the lowest point, it drives the contact plate to move downward, and the contact plate drives the elastic member to move, so that the limit column is separated from the limit hole. When the contact plate is not subjected to force, the contact plate remains in its highest position.

[0011] The technical principle of the scheme of the present invention is: to change the existing earthquake-resistant structure of the building to avoid the unified shock-absorbing method of longitudinal waves and transverse waves, that is, to use limit columns to first limit the shock-absorbing method of the entire earthquake-resistant structure to vibrate up and down, and when the earthquake gradually changes from longitudinal waves (up and down vibrations) to transverse waves (left and right shaking), the left and right earthquake-resistant protection mode of the earthquake-resistant structure is turned on, so that the entire earthquake-resistant structure will not shake left and right due to a small earthquake due to unreasonable setting, thereby prematurely destroying the stability of the lightweight steel structure.

[0012] In the present invention, as a further improvement, one end of the limiting column is a tapered structure. Such a design enables the limiting column to return to its original position more conveniently after leaving the original hole position.

[0013] In the present invention, as a further improvement, the reset member includes a reset spring, one end of the connecting member is connected to the guide wheel of the reset spring, and the other end is connected to the contact plate. When the contact plate is displaced, the reset spring will be pulled back to its original position through the connecting member, so that the limit column can finally return to its original position.

[0014] In the present invention, as a further improvement, the connecting member is a steel wire. Steel wire is the best choice for the connecting member in the present application, and of course other high-strength metals can also be used to achieve the function.

[0015] In the present invention, as a further improvement, the contact plate is connected by a connecting piece, and a steering column is provided at the connection between the connecting piece and the base. That is to say, the contact plate is connected to the guide wheel on the fixed column by a steel wire, and the guide wheel is used in the middle to guide the turning.

[0016] In the present invention, as a further improvement, the reset member also includes a support frame, a guide wheel is provided on the support frame, reset springs are provided on both sides of the rotating shaft, the middle position of the guide wheel is connected to the connecting member, when the connecting member is displaced by force, the guide wheel rotates, and the reset spring is deformed. When the reset spring has completed its deformation, it gradually begins to perform the reset work.

[0017] In the present invention, as a further improvement, at least four anti-vibration springs are arranged between the base and the lower bottom. The function of the anti-vibration springs is to ensure that the base finally returns to the final initial position after the left and right vibrations are finished.

[0018] The outstanding essential features and remarkable improvements of the present invention are:

[0019] 1. The advantage of the present invention is that it changes the problem of premature damage to buildings caused by the integration of longitudinal and transverse wave protection in shock-absorbing buildings in the past, especially for buildings with lightweight structures, such as sun room roofs, lightweight steel frame pointed roof structures and light steel and wood mixed roofs. After research, it was found that the glass on the sun room roof will reduce the life of the glass due to the premature involvement of low-frequency transverse wave vibrations. If the glass quality is poor, it is more likely to burst. The present invention can well overcome this problem.

[0020] 2. The present invention can be well adapted to lightweight building structures by designing the trigger structure of the contact plate and the limit column, and can reduce the seismic resistance problem of lightweight houses with glass structures on the top. At the same time, because the manufactured structure is relatively simple, it can be implemented by combining existing basic equipment with the solution of the present application.

[0021] 3. The present invention has a simple structure and low production cost, and changes the previous structural mode, so it can be conveniently used in a wide range of lightweight building structures. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The present invention is described below with reference to the accompanying drawings and embodiments. Example

[0035] like Figure 1-7 As shown, an earthquake-resistant structure of the present invention includes a top plate 1, a rod 4 is provided at the lower part of the top plate 1, the rod 4 includes an upper rod 4.1 connected to the top plate 1, which can move up and down in a fixed rod 4.2, the fixed rod 4.2 is installed on the upper part of a base 8, a spring member 3 is provided on the periphery of the rod 4, as a shock-absorbing function, the spring member 3 is installed on the periphery of the rod 4 can adopt an existing fixing method such as an rubber ring, when the top plate 1 is not subjected to force, the spring member 3 is only subjected to the natural gravity of the top plate 1, the upper rod 4.1 is in the highest position, a through hole 6 is provided in the base 8, the base 8 is installed in the lower bottom 14, the area of ​​the lower bottom 14 is larger than that of the base 8, in this embodiment, four earthquake-resistant springs 9 connected to the bottom sleeve 13 are provided on the side of the base 8, when the base 8 is not subjected to external force, the center of the base 8 coincides with the center of the lower bottom 14; the outer side of the lower bottom 14 is also provided with a wrapped bottom sleeve 13.

[0036] Limiting holes 7 are provided on the sides of the base 8, and limiting columns 10 that can move left and right are provided in the limiting holes 7. The limiting columns 10 are arranged on steel wires 11. One end of the steel wire 11 is connected to the cross column 18 on the contact plate 5, and the other end passes through the limiting hole 7 and the outer hole 22 of the lower bottom 14, and is connected to the steering column 21 in which the fixing column 12 is arranged through the guide wheel 19. One end of the limiting hole 7 is conical. In the initial state, the conical end penetrates into the outer hole 22 of the lower bottom 14, and most of the tail is in the limiting hole 7, so that the positions of the base 8 and the lower bottom 14 remain fixed. In the present embodiment, four limiting columns 10, four limiting holes 7 and four steel wires 11 are provided, and a reset spring member is provided on the steering column 21. The fixing column 12 is installed on the bottom sleeve 13 during installation.

[0037] A contact plate 5 is also provided in the base 8, a horizontal column 18 for connecting the steel wire 11 is provided on the contact plate 5, the bottom of the contact plate 5 is connected to the telescopic rod 16, and a limit strip 17 is provided on the side of the contact plate 5, which matches the limit groove 15 of the base 8. When the contact plate 5 is not subjected to the contact force of the upper rod 4.1, it is in the highest position.

[0038] The following is the installation and use method of the device of the present invention:

[0039] The present invention is installed in a building structure, such as a light steel glass roof steel structure. The top plate 1 is in contact with and fixed to the upper structure, and the bottom sleeve 13 is fixed to and in contact with the lower structure. The remaining structures are installed according to the schematic diagram. When an earthquake occurs in a building, the longitudinal wave first affects the building, and the rod 4 and the spring member 3 begin to reciprocate up and down due to the vibration. When the amplitude of the longitudinal wave is not large, the upper rod 4.1 vibrates slightly in the fixed rod 4.2 without contacting the contact plate 5. The conical shape of the limiting column 10 penetrates into the outer hole 22 of the lower bottom 14, so that the base 8 remains fixed on the lower bottom 14, thereby ensuring that the building on the top plate 1 will not shake due to the small vibration. As the magnitude of the earthquake increases, the earthquake gradually changes from longitudinal waves (up and down vibrations) to transverse waves (left and right shaking), and the downward floating of the upper rod 4.1 also Gradually increases, when the top plate 1 is subjected to a huge downward external force and the rod 4.1 moves downward significantly, the rod 4.1 passes through the through hole 6 and drives the contact plate 5 to move downward, and the contact plate 5 drives the steel wire 11 to move downward, so that the limit column 10 gradually separates from the outer hole 22 until it reaches its maximum bottom. At this time, since the limit column 10 gradually separates from the outer hole 22 and shrinks into the limit hole 7, there is no direct fixing force between the base 8 and the lower base 14, and since the area of ​​the lower base 14 is larger than that of the base 8, the base 8 can make a small left and right or forward and backward movement in the concave hole in the lower base 14, thereby resisting the transverse waves of the earthquake. (such as Figure 4 ) as shown.

[0040] When the earthquake gradually decreases, the contact plate 5 breaks away from the contact with the upper rod 4.1. Since the other end of the steel wire 11 is connected to the steering column 21, a return spring is provided on the steering column 21. The return spring slowly pulls the steel wire 11 back to its original position, and the limit column 10 gradually returns to its original position. Because the diameter of the outer hole 22 is larger than the conical diameter of the limit column 10, when the cone of the limit column 10 contacts the outer hole 22, it gradually returns to its original position. In this embodiment, the set return spring takes about 5 seconds to pull the steel wire back to its original position. Example

[0041] The difference from the first embodiment is that there are six anti-seismic springs 9 , and by increasing the number of anti-seismic springs, the base 8 is more stable in the lower base 14 .

[0042] Application examples:

[0043] In this application example, Figure 8 As shown, there are 6 earthquake-resistant structures A, which are respectively installed on the columns. The earthquake-resistant structures A passing through the columns are fixed to the upper part of the top plate 1 through the horizontal plate 24 and the vertical plate 23. The horizontal plate 24 and the vertical plate 23 are steel structures with ductility. When an earthquake occurs, the 6 earthquake-resistant structures A have the same overall vibration frequency because of the connection between the horizontal plate 24 and the vertical plate 23. After the limit column 10 is separated from the lower bottom 14, the base 8 can move in the lower bottom 14, and the structures on the horizontal plate 24 and the vertical plate 23 can move as a whole during an earthquake.

[0044] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly illustrating the present invention, and are not intended to limit the implementation. For ordinary technicians in the field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
