Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and in particular relates to a construction structure for high and low raft slab column piers reinforced with steel mesh. Background Technology

[0002] High and low raft slab column piers are foundation components in building foundation engineering that adapt to complex terrain or load differences. They consist of column piers connecting raft slabs of varying heights. High raft slabs are suitable for areas with higher elevations or larger loads, while low raft slabs correspond to areas with lower elevations or smaller loads. The column piers facilitate the transfer of forces and structural connection between the two, balancing foundation settlement and dispersing the upper load. They are suitable for building sites with significant elevation differences.

[0003] Currently, in the construction of high and low raft slab-column pier structures, the stress concentration at the connection between the raft slab and the column pier leads to cracking and uneven settlement, especially in complex sites with large load differences. The structure's shear and crack resistance are insufficient. There is a need to design a high and low raft slab-column pier structure reinforced with steel mesh. After reinforcement with steel mesh, the concentrated stress at the connection between the raft slab and the column pier can be effectively dispersed, improving crack resistance and avoiding cracking and uneven settlement problems, even in complex sites and under conditions with large load differences. At the same time, the steel mesh is easy to install, requiring no complicated procedures, and can balance structural stability and construction efficiency, ensuring the long-term reliability of the foundation project. Utility Model Content

[0004] The purpose of this utility model is to provide a construction structure for high and low raft slab column piers reinforced with steel mesh, which has crack resistance, avoids cracking and uneven settlement problems, and is convenient to construct even in complex sites and under conditions with large load differences. It can also balance structural stability and construction efficiency, and ensure the long-term reliability of foundation engineering, thereby solving the above-mentioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A construction structure for high and low raft slab column piers reinforced with steel mesh includes multiple column pier reinforcements welded to the top of a concrete base. A column pier is fixedly connected to the central axis at the top of the concrete base. Multiple supporting main bars are welded to the inner cavity of the column pier. Multiple horizontal stirrups I are fixedly connected to the surface of the four upper supporting main bars. Multiple horizontal stirrups II are fixedly connected to the surface of the four lower supporting main bars. The horizontal stirrups I and II are symmetrical. Wire mesh I is fixedly connected to both the front and rear sides of the four upper supporting main bars. Wire mesh II is fixedly connected to both the front and rear sides of the four lower supporting main bars. Two diagonal bracing bars I are fixedly connected to the rear side of the four middle supporting main bars. Two diagonal bracing bars II are fixedly connected to the front and rear sides of the four middle supporting main bars.

[0006] Preferably, multiple tie bars are fixedly connected to the surfaces of the four main supporting bars in the middle, and the tie bars are located above the first horizontal stirrup and the second horizontal stirrup.

[0007] Preferably, the inner cavity of the horizontal stirrup is provided with multiple reinforcing bars, and the front and rear ends of the reinforcing bars are respectively fixedly connected to two wire meshes.

[0008] Preferably, the inner cavity of the second horizontal stirrup is provided with a plurality of connecting bars, and the front and rear ends of the connecting bars are respectively fixedly connected to two wire meshes.

[0009] Preferably, a transverse support rib is fixedly connected to the central axis on the opposite side of the first and second diagonal bracing ribs.

[0010] The beneficial effects of this utility model are: 1. This utility model forms a frame by using the supporting main reinforcement, horizontal stirrup one, and horizontal stirrup two in combination. Then, the horizontal stirrup one and horizontal stirrup two are reinforced by using the wire mesh one, diagonal bracing one, and diagonal bracing two in combination. Finally, the steel reinforcement is placed in the inner cavity of the column pier and concrete is poured to make the column pier more solid, thus achieving crack resistance and avoiding cracking and uneven settlement problems, even in complex sites and under conditions with large load differences. At the same time, the steel mesh is easy to construct and does not require complicated procedures. It can take into account both structural stability and construction efficiency, and ensure the long-term reliability of the foundation project. 2. By setting tie bars in the steel cage of the raft column pier at high and low positions, this utility model can effectively enhance the overall rigidity of the steel cage, prevent it from deforming and falling apart during concrete pouring, and can precisely fix the relative position of the main supporting bars and the horizontal stirrups one and two in the steel cage, ensuring that the spacing of the steel bars is compliant. 3. By setting up the transverse support ribs, the transverse support ribs support the first and second diagonal support ribs, ensuring that the second diagonal support ribs will not deform, and improving the stability of the position of the first and second diagonal support ribs when they are fixed at both ends of the main support rib.

[0013] In the following description, embodiments of the construction structure of the high and low raft slab column pier reinforced with steel mesh of this utility model will be described with reference to the accompanying drawings.

[0014] Figure 1-5This invention illustrates a construction structure for a high-low raft foundation column pier reinforced with steel mesh, comprising multiple column pier reinforcement bars 2 welded to the top of a concrete base layer 1. A column pier 3 is fixedly connected to the central axis of the top of the concrete base layer 1. Multiple supporting main reinforcement bars 4 are welded into the inner cavity of the column pier 3. Multiple horizontal stirrups 1 5 are fixedly connected to the surface of the four upper supporting main reinforcement bars 4, and multiple horizontal stirrups 2 6 are fixedly connected to the surface of the four lower supporting main reinforcement bars 4. The horizontal stirrups 1 5 and 2 6 are symmetrical. Multiple tie bars 7 are fixedly connected to the surface of the four middle supporting main reinforcement bars 4. The tie bars 7 are located above the horizontal stirrups 1 5 and 2 6. By setting the tie bars 7, the overall rigidity of the steel cage in the high-low raft foundation column pier reinforcement cage can be effectively enhanced, preventing deformation and disintegration during concrete pouring. It can precisely fix the relative positions of the supporting main reinforcement bars 4 and the horizontal stirrups 1 5 and 2 6 within the steel cage, ensuring compliant reinforcement spacing. The tie bars 7 are located in front of the four upper supporting main reinforcement bars 4. Both sides of the rear are fixedly connected with wire mesh 10. Multiple reinforcing bars 8 are installed inside the cavity of the horizontal stirrup 5. The front and rear ends of the reinforcing bars 8 are fixedly connected to two wire mesh 10 respectively. Multiple connecting bars 9 are installed inside the cavity of the horizontal stirrup 6. The front and rear ends of the connecting bars 9 are fixedly connected to two wire mesh 11 respectively. Wire mesh 11 is fixedly connected to both the front and rear sides of the four supporting main bars 4 located below. Two diagonal bracing bars 12 are fixedly connected to the rear side of the four supporting main bars 4 located in the middle. Two diagonal bracing bars 13 are fixedly connected to the front and rear of the four main supporting bars 4. A transverse supporting bar 14 is fixedly connected to the central axis on the opposite side of the diagonal bracing bars 12 and 13. Through the setting of the transverse supporting bar 14, the transverse supporting bar 14 supports the diagonal bracing bars 12 and 13, ensuring that the diagonal bracing bars 12 and 13 will not deform, and improving the stability of the position of the diagonal bracing bars 12 and 13 when fixed at both ends of the main supporting bars 4.

[0015] Working Principle: During construction, this invention involves first pouring a concrete base layer 1 at a predetermined location on the building foundation. Once the concrete base layer 1 reaches the required strength, multiple column pier reinforcement bars 2 are welded and fixed to the top of the concrete base layer 1 at designed intervals, forming the foundation bearing structure for the column pier construction. Subsequently, the steel cage frame of the column pier 3 is erected. The main supporting reinforcement bars 4 are arranged first, with multiple horizontal stirrups 5 fitted and fixed to the outside of the upper main supporting reinforcement bars, and multiple horizontal stirrups 6 fitted and fixed to the outside of the lower main supporting reinforcement bars. Simultaneously, tie bars 7 are fixed to the surface of the middle main supporting reinforcement bars. The overall rigidity of the steel cage is enhanced by tie bars to ensure the relative stability of the main supporting bars and horizontal stirrups. Then, the steel mesh is reinforced. Reinforcing bars 8 are installed in the inner cavity of horizontal stirrup 15, and their front and rear ends are fixedly connected to the wire mesh 10 on both sides. Connecting bars 9 are installed in the inner cavity of horizontal stirrup 26, and their front and rear ends are fixedly connected to the wire mesh 21 on both sides. Then, diagonal bracing bars 12 and 23 are fixed on the front and rear sides of the main supporting bars in the middle, and transverse supporting bars 14 are fixed at the central axis on the opposite sides to improve the deformation resistance of the steel cage.

[0016] In summary, this high-low raft slab column pier construction structure reinforced with steel mesh forms a frame through the combined use of supporting main reinforcement 4, horizontal stirrup 1 5, and horizontal stirrup 2 6. Then, the combined use of wire mesh 10, diagonal bracing 12, and diagonal bracing 2 13 reinforces horizontal stirrup 1 5 and horizontal stirrup 2 6. Finally, the steel reinforcement is placed inside the column pier 3, and concrete is poured, making the column pier 3 more robust and achieving crack resistance, avoiding cracking and uneven settlement problems, even in complex sites and under conditions of large load differences. Furthermore, the steel mesh construction is convenient, requiring no complex procedures, and can balance structural stability and construction efficiency, ensuring the long-term reliability of the foundation project.
