Description

Technical Field

[0001] The utility model relates to the technical field of hyperbolic steel grid structures, and specifically relates to an earthquake-resistant hyperbolic steel grid structure. Background Technique

[0002] Hyperbolic steel plate is a kind of plate made mainly of steel and processed by special technology. Its characteristic lies in the adoption of a hyperbolic surface structure design, which makes its surface present a typical curve form, similar to the hyperbola in mathematics. This structure not only endows the hyperbolic steel plate with excellent compressive and bending resistance, but also makes it have a unique rhythm aesthetic feeling visually. The structure is stable. The hyperbolic steel plate is made of steel, so it has excellent strength and stability. Its hyperbolic surface structure design makes the mechanical distribution more uniform, effectively reducing the stress concentration phenomenon of the structure, thereby improving the overall bearing capacity and stability. This makes the hyperbolic steel plate have unique advantages in the structural design of large-span buildings and special-shaped buildings, and can meet the needs of various complex building structures.

[0003] For example, an earthquake-resistant hyperbolic steel grid structure with the application number of CN202123204549.7 relates to the technical field of steel grid structures. When installing the steel grid structure, methods such as the bulk method, the sliding method, and the integral hoisting method are mostly used. Traditional installation mostly rigidly connects the support structure of the steel grid structure with the outside. Although the installation is firm, the earthquake resistance effect is weak during or after installation. It includes a steel grid structure, main supports, and a base. Two groups of main supports are fixedly installed at both ends of the steel grid structure. Bases are arranged below both ends of the main supports. An installation frame is fixedly arranged at the top of the base. An activity groove is arranged at the bottom of the installation frame. A limiting hole is opened inside the installation frame. A support column is arranged inside the installation frame. By providing an installation frame, a support column, and a leaf spring, when installing the steel grid structure, it is installed with external equipment through the installation frame, and the shock absorption and buffering effects can be achieved before and after installation. The support column can move in the limiting hole of the installation frame, and the leaf spring enables the support column to achieve a buffering and shock absorption effect no matter how it moves. However, this earthquake-resistant hyperbolic steel grid structure is easily affected by oxidation and corrosion. Over time, the steel grid structure will rust, reducing the service life of the building, and it has poor heat insulation performance. There will be a high-temperature problem in summer, affecting the comfort of the building. Therefore, in view of this, research and improvement are carried out on the existing structural deficiencies, and an earthquake-resistant hyperbolic steel grid structure is proposed. Content of the Utility Model

[0004] The purpose of the utility model is to provide an earthquake-resistant hyperbolic steel grid structure to solve the problems put forward in the above background technique.

[0005] To achieve the above object, the present utility model provides the following technical solution: an earthquake-resistant hyperbolic steel grid structure, including a first base and a damping shock absorber. The top of the first base is fixedly connected with a damping shock absorber, and the top of the damping shock absorber is fixedly connected with a support mechanism. One side of the first base is fixedly connected with a connecting plate, and one side of the support mechanism is fixedly connected with a steel grid main body.

[0006] Preferably, the support mechanism includes carbon steel fixedly connected to the top of the damping shock absorber, and one side of the carbon steel is fixedly connected with glass wool, and one side of the glass wool is fixedly connected with heat-insulating reflective paint.

[0007] Preferably, the bottom of the heat-insulating reflective paint is fixedly connected with a reinforcing plate, and the bottom of the reinforcing plate is fixedly connected to a support rod.

[0008] Preferably, a reinforcing bracket is fixedly connected to the outside of the reinforcing plate, and a fixing pile is fixedly connected to the bottom of the first base.

[0009] Preferably, one side of the support rod is fixedly connected with a second base, and one side of the second base is fixedly connected with a shock-absorbing mechanism, and an arc-shaped plate is arranged on one side of the shock-absorbing mechanism.

[0010] Preferably, the shock-absorbing mechanism includes a hydraulic rod fixedly connected to one side of the second base, a shock-absorbing spring is arranged outside the hydraulic rod, one end of the shock-absorbing spring is fixedly connected with a baffle, and a shock-absorbing rod is arranged on one side of the baffle.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. Through the setting of the support mechanism and the shock-absorbing mechanism, the heat-insulating performance of the steel structure can be increased by arranging glass wool and heat-insulating reflective paint inside the support mechanism, and the surface of the carbon steel is subjected to anti-corrosion treatment. The traditional hyperbolic steel grid structure is easily affected by oxidation and corrosion. Over time, the steel grid structure will rust, reducing the service life of the building, and having poor heat-insulating performance. There will be a problem of high temperature in summer, affecting the comfort of the building. The added glass wool and heat-insulating reflective paint in the present utility model can isolate most of the solar radiation and conduct heat, reduce the formation of the greenhouse effect indoors, thereby greatly reducing the temperature and improving the internal environment of the building where the hyperbolic steel grid structure is located. The shock-absorbing mechanism added to the side of the base can effectively reduce the impact force from the side, reduce the damage to the bottom of the hyperbolic steel grid structure caused by external pressure, and avoid loosening of the hyperbolic steel grid structure, causing irreparable losses;

[0013] 2. By setting the shock-absorbing damping and the arc-shaped plate, the present utility model increases the structural damping inside the damper, consumes the vibration energy of the support mechanism in the earthquake and vibration environment, achieves the reduction of the vibration response of the structure, and realizes the purpose of earthquake resistance and wind resistance of the structure. The arc-shaped plate can not only serve as a bearing mechanism, but also make the hyperbolic steel grid structure more stable and reduce the vibration amplitude. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0020] As Figure 1 - Figure 2 shown, an earthquake-resistant hyperbolic steel grid structure includes a first base 1 and a damping shock absorber 2. The damping shock absorber 2 is fixedly connected to the top of the first base 1, and the support mechanism 3 is fixedly connected to the top of the damping shock absorber 2. A connecting plate 4 is fixedly connected to one side of the first base 1, and the main body of the steel grid 5 is fixedly connected to one side of the support mechanism 3. The damping shock absorber 2 has a cast steel shell and uses alloy springs, with good earthquake-proof effect. The support mechanism 3 connects the first base 1 and the second base 10. Multiple groups of first bases 1 are arranged on one side of the connecting plate 4, and the distance between each group of first bases 1 is the same. An anti-rust coating is attached to the surface of the main body of the steel grid 5 to avoid being eroded by oxidation reaction.

[0021] As Figure 3 - Figure 4 shown, the support mechanism 3 includes a carbon steel 301 fixedly connected to the top of the damping shock absorber 2. One side of the carbon steel 301 is fixedly connected with a glass wool 302, and one side of the glass wool 302 is fixedly connected with a heat-insulating reflective coating 303. The carbon steel 301 has low cost, high strength and good wear resistance. The glass wool 302 can reduce the temperature of the environment where the steel grid structure is located to a certain extent, quickly and efficiently reduce the temperature. The heat-insulating reflective coating 303 can reflect most of the infrared rays, is non-toxic, safe, long-lasting and has a long service life.

[0022] Furthermore, a reinforcing plate 6 is fixedly connected to the bottom of the heat-insulating reflective coating 303, and the bottom of the reinforcing plate 6 is fixedly connected to the support rod 7. The three groups of reinforcing plates 6 form a triangular structure, which is beneficial to increasing the stability of the steel grid structure. The support rod 7 is located at the bottom of the reinforcing plate 6 and the reinforcing bracket 8, and plays a supporting role for the reinforcing plate 6 and the reinforcing bracket 8.

[0023] Furthermore, a reinforcing bracket 8 is fixedly connected to the outside of the reinforcing plate 6, and a fixing pile 9 is fixedly connected to the bottom of the first base 1. The arc of the reinforcing bracket 8 is consistent with the arc of the support mechanism 3, and the arc center of the reinforcing bracket 8 and the support mechanism 3 is at the same place. The fixing piles 9 are symmetrically distributed at the bottom of the first base 1, and the fixing piles 9 make the steel grid structure more stable with the contact surface.

[0024] Furthermore, a second base 10 is fixedly connected to one side of the support rod 7, and a shock-absorbing mechanism 11 is fixedly connected to one side of the second base 10. An arc-shaped plate 12 is arranged on one side of the shock-absorbing mechanism 11. The shock-absorbing mechanism 11 includes a hydraulic rod 1101 fixedly connected to one side of the second base 10. A shock-absorbing spring 1102 is arranged outside the hydraulic rod 1101. One end of the shock-absorbing spring 1102 is fixedly connected to a baffle 1103, and a shock-absorbing rod 1104 is arranged on one side of the baffle 1103. The baffle 1103 is connected to the second base 10 through the hydraulic rod 1101. The shock-absorbing spring 1102 is aligned with the vertical center line of the hydraulic rod 1101, which can reduce the vibration coming from the side of the steel grid structure. The arc-shaped plate 12 effectively decomposes the external impact force.

[0025] Working principle: When using this earthquake-resistant hyperbolic steel grid structure, first fix the steel grid structure to the contact surface through the fixing piles 9 at the bottoms of the first base 1 and the second base 10. A support mechanism 3 composed of carbon steel 301, glass wool 302 and heat-insulating reflective coating 303 is provided at the top of the damping shock absorber 2 to connect the first base 1 and the second base 10. When subjected to external impact, the main body 5 of the steel grid can relieve most of the impact force. The support rods 7 and the strengthening brackets 8 play a supporting role for the main body 5 of the steel grid. When the side of the main body 5 of the steel grid structure is subjected to impact force, the hydraulic rod 1101 and the shock-absorbing spring 1102 inside the shock-absorbing mechanism 11 interact to relieve the external pressure and reduce vibration. The arc-shaped plate 12 on one side of the shock-absorbing rod 1104 effectively decomposes the impact force on the side. This is the working principle of this earthquake-resistant hyperbolic steel grid structure.
