Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and in particular relates to a deformation-resistant reinforcement structure for the connection between the lower column pier and the raft slab. Background Technology

[0002] A raft foundation consists of a base slab, beams, and other integral components. When the building load is large and the foundation bearing capacity is weak, a concrete base slab is often used to support the building load and form a raft foundation. It has good integrity and can effectively resist uneven settlement of the foundation.

[0003] In building construction, the connection between the lower column pier and the raft slab is a crucial node for structural stress. This area may experience stress concentration due to uneven distribution of the upper load and shrinkage deformation after concrete pouring, which can lead to deformation in the connection area. Therefore, it is necessary to design a deformation-resistant reinforcement structure for the connection between the lower column pier and the raft slab. By reinforcing the inner wall of the raft slab, it is possible to prevent the column pier from shifting position when it is connected to the raft slab, enhance the deformation resistance of the connection area, and ensure the structural stability under stress. Utility Model Content

[0004] The purpose of this utility model is to provide a deformation-resistant reinforcement structure for the connection between the lower column pier and the raft slab. It has the advantages of reinforcing the inner wall of the raft slab, preventing the column pier from shifting position when connected to the raft slab, enhancing the deformation resistance of the connection part, and ensuring the structural stress stability, 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 deformation-resistant reinforcement structure for connecting a lower column pier to a raft slab includes raft slab reinforcement fixedly connected to the top of the raft slab, a lower column pier longitudinal reinforcement fixedly connected to the top of the raft slab reinforcement, a lower column pier penetrating through the central axis of the top of the raft slab, multiple vertical reinforcement bars provided at the bottom of the raft slab reinforcement and the lower column pier longitudinal reinforcement bars, all of the multiple vertical reinforcement bars being embedded in the inner cavity of the raft slab, a transverse stirrup fixedly connected to the surface of the four vertical reinforcement bars on the left side, a fixing mesh fixedly connected to the top of the multiple vertical reinforcement bars, the transverse stirrups being located at the bottom of the fixing mesh, two diagonal bracing bars being provided at the bottom of the fixing mesh, both ends of the diagonal bracing bars being fixedly connected to the vertical reinforcement bars, multiple reinforcing bars fixedly connected to the top of the fixing mesh, the multiple reinforcing bars being located around the bottom of the lower column pier, four transverse reinforcing bars fixedly connected to the top of the multiple reinforcing bars, the four transverse reinforcing bars being tightly fitted to the lower column pier.

[0006] Preferably, the surfaces of the four vertical reinforcing bars on the right side are fixedly connected with horizontal stirrups, the horizontal stirrups are symmetrical to each other, and the two diagonal bracing bars are located in the inner cavities of the horizontal stirrups.

[0007] Preferably, tie bars are fixedly connected to the surfaces of the four vertical reinforcing bars in the middle, and the tie bars are located above the first and second transverse stirrups.

[0008] Preferably, the top of the first diagonal brace is fixedly connected to the second diagonal brace, and both ends of the second diagonal brace are fixedly connected to the surface of the vertical reinforcing bar.

[0009] Preferably, a support rib is fixedly connected to the central axis at the top of the first and second diagonal braces, and the tops of the two support ribs are fixedly connected to the fixing net.

[0010] Preferably, the bottom of the plurality of vertical reinforcing bars is fixedly connected with four connecting bars.

[0011] The beneficial effects of this utility model are: 1. This utility model uses vertical steel bars, horizontal stirrups and fixing mesh to reinforce the steel cage inside the raft foundation. Then, by using the reinforcement bars and horizontal reinforcement bars together, a rectangular frame is formed, and the lower pier is fixed in the rectangular frame. The bottom of the lower pier will not shift when the concrete is poured. Finally, the raft foundation steel bars and the longitudinal bars of the lower pier are fixed to the top of the raft foundation. This can achieve the purpose of avoiding the positional shift of the lower pier when it is connected to the raft foundation, enhancing the deformation resistance of the connection part, and ensuring the structural stress stability. 2. By setting up supporting ribs, the two supporting ribs support the top fixing net, ensuring that the fixing net will not sink in the middle when fixed to the top of the vertical steel bar, thus improving the stability of the fixing net supporting the horizontal reinforcing bars.

[0014] In the following description, embodiments of the deformation-resistant reinforcement structure for the connection between the lower column pier and the raft slab of this utility model will be described with reference to the accompanying drawings.

[0015] Figure 1-5 This invention illustrates a deformation-resistant reinforcement structure for the connection between a lower column pier and a raft foundation, according to an embodiment of the present invention. It includes raft foundation reinforcement 2 fixedly connected to the top of the raft foundation 1. A lower column pier longitudinal reinforcement 3 is fixedly connected to the top of the raft foundation reinforcement 2. A lower column 4 is inserted through the central axis of the top of the raft foundation 1. Multiple vertical reinforcement bars 5 are provided at the bottom of the raft foundation reinforcement 2 and the lower column pier longitudinal reinforcement 3, and are embedded in the inner cavity of the raft foundation 1. A transverse stirrup 6 is fixedly connected to the surface of the four vertical reinforcement bars 5 on the left side, and a transverse stirrup 7 is fixedly connected to the surface of the four vertical reinforcement bars 5 on the right side. The transverse stirrups 6 and 7 are symmetrical. Two diagonal bracing bars 10 are located within the inner cavities of the transverse stirrups 6 and 7. Tie bars 8 are fixedly connected to the surface of the four vertical reinforcement bars 5 in the middle, located above the transverse stirrups 6 and 7. A fixing mesh 9 is fixedly connected to the top of the multiple vertical reinforcement bars 5, and the transverse stirrups 6 are located at the bottom of the fixing mesh 9. The bottom of the fixing mesh 9 is provided with… There are two diagonal bracing bars 10, both ends of which are fixedly connected to the vertical reinforcing bars 5. The top of the diagonal bracing bars 10 is fixedly connected to the diagonal bracing bars 21, both ends of which are fixedly connected to the surface of the vertical reinforcing bars 5. The central axis of the top of the diagonal bracing bars 10 and 21 is fixedly connected to the support bars 12. The top of the two support bars 12 is fixedly connected to the fixing net 9. Through the setting of the support bars 12, the two support bars 12 play a supporting role for the top fixing net 9, ensuring that the fixing net 9 is fixed to the top of the vertical reinforcing bars 5 and will not sink in the middle position, thus improving the stability of the fixing net 9 in supporting the transverse reinforcing bars 15. The bottom of the multiple vertical reinforcing bars 5 is fixedly connected to four connecting bars 13. The top of the fixing net 9 is fixedly connected to multiple reinforcing bars 14. The multiple reinforcing bars 14 are located around the bottom of the lower pier column 4. The top of the multiple reinforcing bars 14 is fixedly connected to four transverse reinforcing bars 15. The four transverse reinforcing bars 15 are tightly attached to the lower pier column 4.

[0016] Working principle: When using this utility model, during construction, multiple vertical reinforcing bars 5 are first inserted into the inner cavity of the raft slab 1. Horizontal stirrups 6 are fixed to the surfaces of the four vertical reinforcing bars 5 on the left, and horizontal stirrups 7 are fixed to the surfaces of the four vertical reinforcing bars 5 on the right. Tie bars 8 are fixed to the surfaces of the four vertical reinforcing bars 5 in the middle. Simultaneously, diagonal bracing bars 10 are set at the bottom of the horizontal stirrups 6 and 7, and diagonal bracing bars 11 are set at the top. The diagonal bracing bars 10 and 11 are connected to the top fixed bracing bars 12 via supporting bars 12. The bottom of the fixed mesh 9 and the vertical steel bars 5 are reinforced by the connecting bars 13. Then, multiple reinforcing bars 14 are fixed at the top of the fixed mesh 9, and four transverse reinforcing bars 15 that are closely attached to the lower pier column 4 are fixed at the top of the reinforcing bars 14 to form a limiting structure around the bottom of the lower pier column 4. Then, the raft slab steel bars 2 are fixed to the top of the raft slab 1, and the longitudinal bars 3 of the lower pier are fixedly connected to the top of the raft slab steel bars 2. Finally, concrete is poured to make the position of the lower pier column 4 fixed at the central axis of the inner cavity of the raft slab 1 more stable.

[0017] In summary, the deformation-resistant reinforcement structure connecting the lower column pier to the raft slab reinforces the inner cavity of the raft slab 1 with the combined use of vertical reinforcing bars 5, horizontal stirrups 6, and fixing mesh 9. Then, the combined use of reinforcing bars 14 and horizontal reinforcing bars 15 forms a rectangular frame, fixing the lower column 4 within this frame. This prevents the bottom of the poured concrete lower column pier 4 from shifting. Finally, the raft slab reinforcing bars 2 and the lower column pier longitudinal bars 3 are fixed to the top of the raft slab 1. This achieves the goal of preventing the column pier from shifting position when connected to the raft slab, enhancing the deformation resistance of the connection, and ensuring the structural stability.
