Description

Technical Field

[0001] This utility model belongs to the field of raft construction technology, and in particular relates to a construction connection structure between a basement raft slab and connecting reinforcement bars. Background Technology

[0002] The raft slab and connecting bars are crucial components of the underground parking garage structure. They work together to ensure the stability and load-bearing capacity of the underground parking garage foundation. It is like a huge slab that covers the bottom area of ​​the underground parking garage. The function of the raft slab is to evenly distribute the load from the superstructure of the underground parking garage onto the foundation, avoiding uneven settlement caused by excessive local stress on the foundation.

[0003] Raft foundations are generally constructed using reinforced concrete. Often, a single stirrup is used to connect and support the foundation reinforcement frame and the top reinforcement frame. During concrete pouring, the impact and vibration of the concrete can easily cause the reinforcement frame to shift or deform, resulting in uneven reinforcement distribution and affecting the overall mechanical properties of the raft foundation. Therefore, a construction connection structure between the raft foundation and the connecting reinforcement is needed. Through the rational arrangement of the foundation and top reinforcement frames, a stable support framework is provided for the raft foundation pouring. Simultaneously, the reinforcement components further enhance the support strength of the top reinforcement frame, preventing displacement during pouring. Utility Model Content

[0015] Figure 1-4This invention illustrates a construction connection structure for a basement raft foundation and connecting reinforcement bars according to an embodiment of the present invention. The structure includes a raft foundation 2 cast on top of a building foundation 1; a foundation reinforcement frame 3 located inside the raft foundation 2 is laid on top of the building foundation 1; a top-level reinforcement frame 4 located inside the raft foundation 2 is laid on top of the foundation reinforcement frame 3; multiple support plates 5 are welded between the raft foundation 2 and the foundation reinforcement frame 3; support columns 6 are welded to the top of the support plates 5; and a reinforcement component 7 is provided on the top of the support plates 5. The reinforcement component 7 includes two horizontal bars 71 welded to the top of both sides of the support columns 6. The top of the support plate 5 contacts the top-level steel reinforcement frame 4. Two steel reinforcement sections 72 are welded to the top of the crossbar 71, and these sections 72 engage with the surface of the top-level steel reinforcement frame 4. Both the steel reinforcement sections 72 and the crossbar 71 are welded and fixed to the top-level steel reinforcement frame 4. Inclined steel pipes 73 are welded to both sides of the top of the support plate 5. Y-shaped reinforcing ribs 74 are welded to the inner cavity of the inclined steel pipes 73. The top of the Y-shaped reinforcing ribs 74 is tightly fitted to the bottom of the top-level steel reinforcement frame 4, and the top of the Y-shaped reinforcing ribs 74 is welded and fixed to the top-level steel reinforcement frame 4. The bottom end of the Y-shaped reinforcing ribs 74 is welded to the top of the inclined steel pipes 73. Openings are made on both sides of the bottom of the support plate 5. A slot 75 is provided, which engages with the top of the foundation steel reinforcement frame 3. The edge of the inner wall of the slot 75 is welded and fixed to the surface of the foundation steel reinforcement frame 3. Through the setting of the reinforcement component 7, the crossbar 71 provides horizontal support for the top layer steel reinforcement frame 4, ensuring the stability of the spacing between the foundation steel reinforcement frame 3 and the top layer steel reinforcement frame 4. At the same time, with the cooperation of the steel bar section 72, the top layer steel reinforcement frame 4 is limited and blocked to prevent displacement during the pouring process. With the cooperation of the Y-shaped reinforcing bar 74, the top layer steel reinforcement frame 4 is diagonally reinforced, further improving the top layer steel reinforcement. The support strength of the frame 4, together with the use of the slot 75, allows the support plate 5 to be stably engaged on the surface of the foundation steel frame 3, improving the stability of the support plate 5 and the support column 6 after installation. Multiple U-shaped stirrups 8 are distributed on the four sides of the top layer steel frame 4 and the foundation steel frame 3. Multiple closed stirrups 9 are provided on the surface of the U-shaped stirrups 8. The closed stirrups 9 are welded and fixed to the inside of the raft foundation 2.

[0016] Working Principle: In use, the user lays the foundation steel reinforcement frame 3, tying the steel reinforcement joints with wire. Then, the support plate 5 is moved to the top of the foundation steel reinforcement frame 3, allowing the slot 75 to engage with the surface of the foundation steel reinforcement frame 3. The joints are welded and fixed, and the Y-shaped reinforcing rib 74 is inserted into the inner cavity of the inclined steel pipe 73. Next, the top layer steel reinforcement frame 4 is laid. After the top layer steel reinforcement frame 4 is laid, the Y-shaped reinforcing rib 74 is pulled upwards, causing it to slide within the inner cavity of the inclined steel pipe 73, with its top and bottom... The bottom of the top layer steel reinforcement frame 4 is attached, and then welding is performed at the contact position between the top layer steel reinforcement frame 4 and the Y-shaped reinforcing bar 74. The top of the inclined steel pipe 73 is welded and fixed to the surface of the Y-shaped reinforcing bar 74. Then, the steel bar section 72 is moved to the side of the surface steel reinforcement of the top layer steel reinforcement frame 4 and welded and fixed at the contact position. Then, multiple U-shaped stirrups 8 are distributed around the foundation steel reinforcement frame 3 and the top layer steel reinforcement frame 4 and welded and fixed. Finally, the user seals the edges of the closed stirrups 9 around the surface of the multiple U-shaped stirrups 8, and then the raft foundation 2 is formed by pouring concrete.

[0017] In summary, the construction connection structure between the raft foundation and the connecting reinforcement bars, through the combined use of the foundation reinforcement frame 3 and the top reinforcement frame 4, provides a stable support framework for the raft foundation 2 before pouring. Simultaneously, the combined use of the support plate 5, support columns 6, and U-shaped stirrups 8 provides support between the foundation reinforcement frame 3 and the top reinforcement frame 4, ensuring the stability and uniform distribution of the framework formed by the foundation reinforcement frame 3 and the top reinforcement frame 4, thus achieving the goal of structural support stability and increased load-bearing strength.
