Description

Technical Field

[0001] This utility model relates to the field of wide and flat beam technology, and in particular to a steel-concrete composite wide and flat beam. Background Technology

[0002] When the width of a beam is greater than its height, it is called a wide-flat beam. The height-to-width ratio of a typical rectangular beam is generally between 2.0 and 3.5, while the height-to-width ratio of a wide-flat beam is less than this range.

[0003] As described in announcement number CN217461178U, a wide and flat steel-concrete composite beam is provided, which is equipped with a concrete floor slab. Multiple I-beams are arranged horizontally and evenly within the concrete floor slab, forming a wide and flat steel-concrete beam. The height of this wide and flat beam is less than that of a normal steel-concrete beam, effectively solving the problem of insufficient building height. Multiple steel-concrete web reinforcements are provided within the concrete floor slab and at the middle position of the I-beams. Multiple steel-concrete stirrups and steel-concrete tie bars are provided between the multiple steel-concrete web reinforcements. The multiple steel-concrete web reinforcements, stirrups, and tie bars form a three-dimensional mesh structure around the I-beams to increase the overall strength of the wide and flat steel-concrete beam. This wide and flat beam has a strong resistance to bending and shear force ratio, and a relatively small cross-sectional height, saving indoor space.

[0004] This patented technology has a strong ability to withstand resistance and bending shear force ratio, and a relatively small cross-sectional height, saving indoor space. However, existing wide and flat beams do not have seismic resistance. Under earthquake action, wide and flat beams with low vertical stiffness may not be able to effectively resist seismic forces, resulting in a decrease in the overall stability of the structure and thus affecting the safety of the structure.

[0005] Therefore, we propose a novel type of steel-concrete composite wide flat beam. Utility Model Content

[0009] Furthermore, the guide plate and the guide groove form an interlocking connection, the first spring and the first damping push plate form an elastic structure, and the outer surface of the first damping push plate is in contact with the inner wall of the first slot.

[0010] Furthermore, the first damping push plate is rotatably connected to the connecting rod via a first rotating shaft, and the connecting rod is rotatably connected to the top beam via a second rotating shaft.

[0011] Furthermore, the second damping push plate and the second spring form an elastic structure, and the outer surface of the second damping push plate is in contact with the inner wall of the second slot.

[0027] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0029] Example 1, as Figure 1 - Figure 3 As shown, this utility model provides a steel-concrete composite wide and flat beam, including a wide and flat beam body 1. An anti-seismic component 2 is installed inside the wide and flat beam body 1. First slots 201 are opened on both sides of the anti-seismic component 2. A first spring 202 is connected inside the first slot 201. A first damping push plate 203 is connected to the top of the first spring 202. A top block 204 is connected to the top of the first damping push plate 203. A second slot 208 is opened on the side of the wide and flat beam body 1 near the first slot 201. A second spring 209 is connected inside the second slot 208. A second damping push plate 210 is connected to one side of the second spring 209. A first rotating shaft 211 is connected to the top of the second damping push plate 210. A connecting rod 212 is connected to the surface of the first rotating shaft 211. A second rotating shaft 213 is connected to one side of the connecting rod 212. A top beam 207 is fixedly connected to the top of the second rotating shaft 213. Guide plates 205 are connected to the bottom of both sides of the top beam 207. A guide groove 206 is provided on the other side of the flat beam body 1 near the first slot 201. The guide plate 205 is rectangular in shape, and its position and size match the position and size of the guide groove 206. The guide plate 205 and the guide groove 206 form an interlocking connection. The first spring 202 and the first damping push plate 203 form an elastic structure. The outer surface of the first damping push plate 203 is in contact with the inner wall of the first slot 201. The first damping push plate 203 passes through the first... The rotating shaft 211 and the connecting rod 212 form a rotatable connection. The connecting rod 212 is rotatably connected to the top beam 207 through the second rotating shaft 213. The second damping push plate 210 and the second spring 209 form an elastic structure. The outer surface of the second damping push plate 210 is in contact with the inner wall of the second slot 208. The second damping push plate 210 and the second spring 209 form an elastic structure. The outer surface of the second damping push plate 210 is in contact with the inner wall of the second slot 208.

[0030] The overall effect of Embodiment 1 is that when the wide and flat beam body 1 vibrates after installation, the vibration force causes the top beam 207 to move downward. When the top beam 207 presses downward, it pushes the first damping push plate 203 through the top block 204 to compress the first spring 202, thus achieving a shock absorption effect. The first damping push plate 203 also rubs against the inner wall of the first slot 201, achieving a damping effect. At the same time, the second rotating shaft 213 also rotates with the connecting rod 212, allowing the connecting rod 212 to rotate with the first rotating shaft 211, thereby enabling the first rotating shaft 211 to push the second damping push plate 210 to compress the second spring 202. The compression of spring 09 enhances the shock absorption effect. The first spring 202 and the second spring 209, as the main energy absorption elements, can absorb and store a large amount of vibration energy, thereby reducing the vibration amplitude of the wide and flat beam body 1. The friction between the first damping push plate 203 and the inner wall of the first slot 201 further consumes the vibration energy and improves the shock absorption effect. At this time, the guide plate 205 will also slide in the guide groove 206, playing a guiding role. It ensures the stability and directionality of the top beam 207 when it moves downward, prevents the deviation or swaying caused by vibration, and thus achieves the anti-seismic effect, improving the stability of the wide and flat beam body 1 structure and the safety during use.

[0031] Example 2, as Figure 1 - Figure 3 As shown, a height adjustment component 3 is connected to the bottom of the second slot 208. The height adjustment component 3 includes a base 301. Slots 302 are provided at both the front and rear ends of the base 301. Sliding holes 303 are provided at the four corners of the base 301. Bolts 304 are inserted into the interior of both sides of the base 301. Sliding rods 305 are connected to the four corners of the bottom of the wide flat beam body 1. Insert plates 306 are connected to the front and rear ends of the bottom of the wide flat beam body 1. Threaded holes 307 are provided on the outer surface of the insert plates 306. The outer surface of the sliding rods 305 fits against the inner wall of the sliding holes 303, forming a sliding connection between the sliding rods 305 and the sliding holes 303. An insertion connection is formed between the sliding rods 305 and the slots 302. The bolts 304 pass through the base 301 and form a threaded connection with the threaded holes 307.

[0032] The overall effect of Embodiment 2 is that when the height of the wide and flat beam body 1 needs to be adjusted due to different construction environments, all bolts 304 can be removed from the bolts 304 at the current height, and then the wide and flat beam body 1 can be lifted up so that the insert plate 306 can slide in the slot 302 and drive the slide rod 305 to slide in the slide hole 303. This ensures the stability and directionality of the wide and flat beam body 1 during the height adjustment process. When the height is adjusted to the appropriate position, the bolts 304 can be threaded through the base 301 and fixed with the threaded hole 307 at the current position. The threaded hole 307 is flexibly arranged at multiple height positions, so that the wide and flat beam body 1 can be adjusted to different heights according to different environments. This allows it to better adapt to different installation environments and structural requirements, reduces restrictions during the installation process, and improves construction efficiency.

[0033] Working principle: When the wide and flat beam body 1 is installed and vibration occurs, the first spring 202 and the second spring 209 can effectively resist the vibration. The guide plate 205 and guide groove 206 are also provided to guide the beam during vibration, which improves the stability of the structure and the safety during use. When installing the wide and flat beam body 1, the overall height of the wide and flat beam body 1 can be adjusted according to the actual situation. By adjusting the overall height of the wide and flat beam body 1, it can better adapt to different installation environments and structural requirements, reduce the restrictions in the installation process, and improve construction efficiency.

[0034] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
