Description

Technical Field

[0001] This utility model relates to the technical field of H-beam and concrete composite support structure, specifically a building H-beam and concrete composite support structure. Background Technology

[0002] From a structural perspective, steel-concrete composite structures possess the advantages of both steel and concrete structures. Compared to reinforced concrete structures, due to their higher steel content, steel-concrete composite members have a greater load-bearing capacity for the same cross-section; they also exhibit good ductility and seismic performance. The H-shaped steel frame can be prefabricated in a factory, accelerating on-site construction. Compared to steel structures, the concrete encasing the H-shaped steel-concrete composite member increases the stiffness of the steel component. For the same steel content, H-shaped steel-concrete composite members have greater stiffness than steel structural members. Furthermore, the concrete encasing the H-shaped steel-concrete composite member enhances the fire resistance, corrosion resistance, and stability of the steel component.

[0003] From the perspective of local stability, conventional H-beams are prone to local buckling in their flanges and webs due to stress concentration when subjected to complex loads. Once local buckling occurs, it not only weakens the load-bearing capacity of the H-beam itself but may also trigger a chain reaction, affecting the stability of the entire supporting structure. For example, in some large-span buildings or buildings subjected to significant wind loads or seismic forces, insufficient local stability may cause H-beams to deform or even fail prematurely, threatening building safety. Utility Model Content

[0004] The purpose of this utility model is to provide a combined H-beam and concrete support structure for buildings to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a combined support structure of H-beams and concrete for building construction, comprising H-beams and concrete, wherein a reinforcing mechanism is provided within the steel channel of the H-beams, and a fixing mechanism is provided within the reinforcing mechanism;

[0006] The reinforcement mechanism includes a sliding member, which is symmetrically and fixedly connected to the inner wall of an H-shaped steel channel. A sliding column is slidably connected to the inner wall of the sliding member. Limiting blocks are symmetrically and fixedly connected to the front and rear sides of the sliding column. Limiting grooves matching the limiting blocks are opened on the front and rear sides of the inner wall of the sliding member.

[0007] Preferably, the limiting block surface is slidably connected to the limiting groove to limit the sliding column, so that the sliding column will not move left or right within the sliding member.

[0008] Preferably, the fixing mechanism includes a fixing frame, which is fixedly connected to the sliding member on the side near the H-beam cross plate. Guide rods are symmetrically arranged on the other side of the fixing frame. A fixing ring is fixedly connected to one end of the surface of the guide rod. A spring is sleeved between the inner wall of the fixing frame and the fixing ring on the surface of the guide rod. A locking block is fixedly connected to one end of the guide rod, and a pull plate is fixedly connected to the other end of the guide rod.

[0009] Preferably, the fixing frame is therefore provided with a hole that matches the guide rod, and the surface of the guide rod passes through and slides up and down within the hole.

[0010] Preferably, one end of the spring is fixedly connected to the side of the fixed ring away from the sliding member, and the other end of the spring is fixedly connected to the inner wall of the fixed frame.

[0011] Preferably, the locking block is engaged with the surface of the sliding column by the elastic force of the spring, thereby limiting the sliding column and preventing it from moving up and down easily.

[0012] Compared with the prior art, this utility model provides a composite support structure of H-beams and concrete for buildings, which has the following advantages:

[0013] 1. This building utilizes a composite support structure of H-beams and concrete. The ingenious design of the reinforcement mechanism greatly enhances the local stability of the H-beams. The cooperation between the sliding components and the sliding columns, along with the setting of limiting blocks and limiting grooves, precisely constrains the movement of the sliding columns within the H-beam grooves. During actual stress loading, when the flanges and webs of the H-beams are subjected to stresses that could lead to local buckling, the sliding columns can flexibly adjust their position up and down within the sliding components. Simultaneously, the sliding of the limiting blocks within the limiting grooves restricts their lateral displacement, ensuring that the stress on the local areas of the H-beams remains stable, effectively resisting local buckling and guaranteeing the safe operation of the structure under complex stress environments.

[0014] 2. The building utilizes a combined H-beam and concrete support structure, and its fixing mechanism greatly facilitates construction. During concrete filling, pulling the pull plate disengages the locking block from the sliding column, allowing for flexible adjustment of the sliding column's position and providing sufficient space for concrete filling, preventing structural obstruction from causing incomplete concrete compaction. After filling is complete, releasing the pull plate causes the locking block to re-engage with the sliding column surface under spring force, limiting the sliding column's position and ensuring its stability.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] This utility model provides the following technical solution:

[0025] Example 1

[0026] Please see Figures 1-4 This utility model provides a technical solution: a combined support structure of H-beams and concrete for building construction, including H-beams 1 and concrete 2, a reinforcing mechanism 3 is provided in the steel channel of H-beams 1, and a fixing mechanism 4 is provided in the reinforcing mechanism 3.

[0027] The reinforcement mechanism 3 includes a sliding member 31. The sliding member 31 is symmetrically and fixedly connected to the inner wall of the steel channel of the H-beam 1. The inner wall of the sliding member 31 is slidably connected to the sliding column 32. The sliding column 32 is symmetrically and fixedly connected to the front and rear sides of the sliding column 32. The inner wall of the sliding member 31 is provided with a limiting groove 34 that matches the limiting block 33.

[0028] The limiting block 33 is slidably connected to the limiting groove 34 on its surface to limit the sliding column 32, so that the sliding column 32 will not move left or right within the sliding member 31.

[0029] Example 2

[0030] Please see Figure 5 Furthermore, based on Embodiment 1, a fixing mechanism 4 is obtained.

[0031] The fixing mechanism 4 includes a fixing frame 41, which is fixedly connected to the sliding member 31 on the side near the horizontal plate of the H-beam 1. Guide rods 42 are symmetrically arranged on the other side of the fixing frame 41. A fixing ring 43 is fixedly connected to one end of the surface of the guide rod 42. A spring 44 is sleeved between the inner wall of the fixing frame 41 and the fixing ring 43 on the surface of the guide rod 42. A locking block 45 is fixedly connected to one end of the guide rod 42. A pull plate 46 is fixedly connected to the other end of the guide rod 42.

[0032] The fixing bracket 41 is therefore provided with a hole that matches the guide rod 42, and the guide rod 42 is slidably connected to the hole through the surface of the guide rod 42.

[0033] One end of the spring 44 is fixedly connected to the side of the fixed ring 43 away from the sliding member 31, and the other end of the spring 44 is fixedly connected to the inner wall of the fixed frame 41.

[0034] The locking block 45 is engaged with the surface of the sliding post 32 by the elastic force of the spring 44, limiting the sliding post 32 so that it will not move up and down easily.

[0035] In actual operation, when this device is used, the sliding member 31 in the reinforcing mechanism 3 is symmetrically and fixedly connected to the inner wall of the steel channel of the H-beam 1. The sliding column 32 can slide up and down on the inner wall of the sliding member 31. To limit the left and right movement of the sliding column 32, limiting blocks 33 are symmetrically and fixedly connected to the front and rear sides of the sliding column 32. At the same time, limiting grooves 34 matching the limiting blocks 33 are opened on the front and rear sides of the inner wall of the sliding member 31. When the H-beam 1 is subjected to external load, it will deform to a certain extent. At this time, the sliding column 32 will slide up and down in the sliding member 31 to adapt to this deformation. The limiting blocks 33 slide up and down in the limiting grooves 34, ensuring that the sliding column 32 can only move in the up and down direction, avoiding left and right swaying. This design enables the reinforcement mechanism 3 to enhance the local stability of the H-beam 1 and improve its resistance to deformation, thereby better transferring the load to the entire support structure. The fixing mechanism 4 includes a fixing frame 41, a guide rod 42, a fixing ring 43, a spring 44, a locking block 45, and a pull plate 46. The fixing frame 41 is fixedly connected to the side of the sliding member 31 near the horizontal plate of the H-beam 1. The guide rod 42 is symmetrically arranged on the other side of the fixing frame 41, and a fixing ring 43 is fixedly connected to one end of the surface of the guide rod 42. A spring 44 is sleeved between the inner wall of the fixing frame 41 and the fixing ring 43 on the surface of the guide rod 42. One end of the spring 44 is fixedly connected to the side of the fixing ring 43 away from the sliding member 31, and the other end is fixedly connected to the inner wall of the fixing frame 41. One end of the guide rod 42 is fixedly connected to a locking block 45, and the other end is fixedly connected to a pull plate 46. Under normal use, the spring 44 is in a compressed state, and its elastic force pushes the fixing ring 43, thereby causing the guide rod 42 to drive the locking block 45 to engage with the surface of the sliding column 32, limiting the sliding column 32 and preventing it from moving up and down easily. This ensures that the reinforcement mechanism 3 works in a stable state, enhancing the stability of the entire support structure.
