Description

Technical Field

[0001] The utility model relates to the technical field of rigid concrete shear wall construction and is suitable for the construction of inclined ultra-thick rigid concrete shear wall formwork structure. Background Art

[0002] The application of inclined ultra-thick rigid concrete shear wall formwork structure is becoming more and more widespread, but the particularity of this structure determines that its high formwork construction is quite difficult. Before pouring the shear wall concrete, a guide wall should usually be made according to the axis of the shear wall structure, and the large formwork should be fixed on the guide wall and the gap should be sealed with plastic film and other materials to avoid leakage during the concrete pouring process. However, this node is still easy to become a difficult point in the control of the shear wall construction process, and the connection between the guide wall and the newly built shear wall is easy to become a structural weak point. In addition, during the construction of the inclined concrete shear wall, since the large formworks on both sides of the shear wall are in an unbalanced stress state, it is easy for the formwork to shift and collapse due to the unreliable fixation of the formwork.

[0003] Therefore, there is an urgent need for an inclined ultra-thick rigid concrete shear wall formwork structure with reliable formwork fixation. Utility Model Content

[0009] The formwork on the right is supported by a number of struts, which are anchored to the base plate by strut bases, and the formwork on the left is tied by a number of tie rods.

[0010] Furthermore, the lower frame of the frame structure extends to the right side of the guide wall, and the lower frame is pressed onto the base plate through the first base, and the first base is anchored to the base plate through the anchor rod; the lower frame of the frame structure extends to the left side of the guide wall, and the lower frame is pressed onto the base plate through the second base and the third base, and the second base and the third base are anchored to the base plate through the anchor rod.

[0020] 4. The utility model utilizes the pipelines arranged inside the template to carry out cooling water circulation and heat dissipation maintenance, thereby realizing the internal maintenance of the ultra-thick concrete shear wall. BRIEF DESCRIPTION OF THE DRAWINGS

The template bottom frame includes a lower left horizontal rib 16 located at the junction of the left side of the guide wall 2 and the bottom plate 1, and an upper left horizontal rib 17 at the top of the left side of the guide wall 2. The lower left horizontal rib 16 and the upper left horizontal rib 17 are arranged in parallel, and a left vertical rib 18 is arranged between the lower left horizontal rib 16 and the upper left horizontal rib 17. Similarly, on the other side, that is, the right side of the guide wall 2, a lower right horizontal rib 24 located at the junction of the right side of the guide wall 2 and the bottom plate 1 and an upper right horizontal rib 25 at the top of the right side of the guide wall 2 are arranged. The lower right horizontal rib 24 and the upper right horizontal rib 25 are arranged in parallel, and a right vertical rib 23 is arranged between the lower right horizontal rib 24 and the upper right horizontal rib 25. On the periphery of the side plate 13 on the side of the guide wall 2, there are an upper frame 14 connecting the upper left horizontal rib 17 and the upper right horizontal rib 25, and a lower frame 11 connecting the lower left horizontal rib 16 and the lower right horizontal rib 24, and a limit block 12 is provided between the lower frame 11 and the side plate 13.
