Description

Technical Field

[0001] The utility model relates to the field of steel bar trusses, in particular to a steel bar truss with an anti-seismic function. Background Art

[0002] Among the traditional earthquake-proof measures for building structures, the commonly used base isolation technology is to set up isolation bearings between the building foundation and the ground to reduce the vibration energy transmitted by seismic waves to the upper structure. However, this traditional method has many shortcomings in practical applications. First, the isolation effect is limited. Traditional isolation design often focuses on the use of standardized isolation bearings, such as laminated rubber bearings. Although these bearings have certain isolation effects, their adaptability and flexibility are relatively insufficient when facing complex and changeable earthquake waves, and they are often unable to effectively disperse and absorb large vibration energy, resulting in the building structure still being damaged under strong earthquakes. Secondly, the construction process is complicated, and a large number of construction operations need to be carried out between the building foundation and the ground, which increases the difficulty and risk of construction. Utility Model Content

[0003] The purpose of the present invention is to provide a steel truss with an anti-seismic function to solve the problems raised in the above background technology.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] A steel truss with an earthquake-proof function comprises: a bottom form, an earthquake-proof component is fixed on the upper side of the bottom form, and the steel truss is attached to the upper side of the earthquake-proof component;

[0006] The shockproof component includes a connecting plate, a buffer component is provided on the lower side of the connecting plate, a bottom mold is fixed on the lower side of the buffer component, a fixing plate is welded on the inner side of the connecting plate, and a bolt is embedded on one side of the fixing plate;

[0007] The buffer component includes a support plate, a screw is provided on the inner side of the support plate, the screw is threadedly connected to the inner side of the bottom mold, a fixing column is fixed on the upper side of the support plate, and a rectangular spring is fixed on the upper side of the support plate.

[0008] Preferably, a connecting plate is fixed to the top of the rectangular spring, and both the connecting plate and the rectangular spring are attached to the outer side of the fixing column.

[0009] The vibration energy is transmitted to the shock-proof component through the fixing plate (the shock-proof component is first fixed to the bottom formwork by screws set on the support plate). The rectangular spring in the shock-proof component serves as the main buffer element, which can further absorb and dissipate the vibration energy. The elastic deformation of the rectangular spring can reduce the direct impact of the vibration on the bottom formwork, thereby protecting the bottom formwork and the structure above it from damage. The support plate and fixed column play a role in supporting and transmitting force, ensuring that the rectangular spring can work stably and reducing the damage of vibration to the internal structure of the building.

[0010] Preferably, the support plate is a "triangle" structure.

[0011] The supporting plate has a "triangle" structure and can form an internal buffer area, which is convenient for connecting plates and fixing plates to perform buffering.

[0012] Preferably, threaded holes corresponding to the screws are provided on the bottom mold and the support plate.

[0013] Preferably, the fixing plate is provided with reserved holes corresponding to the bolts.

[0014] Preferably, the steel truss includes support transverse steel bars, the support transverse steel bars are fixed to the inner side of the fixed plate, the support vertical steel bars are welded to the outer side of the support transverse steel bars, the upper side of the support vertical steel bars is welded with upper chord steel bars, and the upper side of the support transverse steel bars is welded with two lower chord steel bars.

[0015] Preferably, the steel truss further includes web steel bars, and the web steel bars are welded between the upper chord steel bars and the lower chord steel bars.

[0016] The reinforced truss includes support transverse reinforcement, support vertical reinforcement, upper chord reinforcement, lower chord reinforcement and web reinforcement, which can initially disperse and absorb part of the vibration energy.

[0017] Compared with the prior art, the present invention provides a steel truss with earthquake-proof function, which has the following beneficial effects:

[0018] The utility model preliminarily disperses and absorbs external vibration energy through the steel truss, and then transmits the vibration energy to the rectangular spring in the shock-proof component as a buffer element through the fixed plate, which further absorbs and dissipates the vibration energy. The elastic deformation characteristics of the rectangular spring enable it to effectively reduce the impact of vibration on the bottom form and the structure above it, thereby protecting these building structures from damage. Compared with traditional shock-proof measures, the utility model has better vibration absorption effect; and during the installation process, the utility model adopts bolts to connect the fixing plate, preliminarily fix the transverse steel bars of the support, and then adjust the deployment position before welding and fixing. This installation method is simple and firm, which not only improves construction efficiency but also reduces construction costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] A connecting plate 22 is fixed to the top of the rectangular spring 214 , and both the connecting plate 22 and the rectangular spring 214 are attached to the outside of the fixing column 213 .

[0032] The vibration energy is transmitted to the shock-proof component 2 through the fixing plate 23 (the shock-proof component 2 is first fixed to the bottom mold 1 by the screws 212 set on the support plate 211). The rectangular spring 214 in the shock-proof component 2 serves as the main buffer element, which can further absorb and dissipate the vibration energy. The elastic deformation of the rectangular spring 214 can reduce the direct impact of the vibration on the bottom mold 1, thereby protecting the bottom mold 1 and the structure above it from damage.

The rectangular spring 214 in the shockproof component 2 serves as the main buffer element, which can further absorb and dissipate the vibration energy. The rectangular spring 2 The elastic deformation of 14 can slow down the direct impact of vibration on the bottom form 1, thereby protecting the bottom form 1 and the structure above it from damage. The support plate 211 and the fixed column 213 play the role of supporting and transmitting force, ensuring that the rectangular spring 214 can work stably and reduce the damage of vibration to the internal structure of the building.

After adjusting the accurate deployment position, the bolts 24 and the support transverse steel bars 31 are welded and fixed.
